To investigate whether incorporating the measurement of ADAM12 in the risk calculation program LifeCycle, can improve Down screening in the first trimester. In a retrospective case control study, maternal serum ADAM12 concentrations were measured and compared in Down syndrome cases (n = 53) and in controls (n = 226) obtained from first trimester (9-12 weeks) screening samples in Oulu and Kuopio University Hospitals. Median concentration ( microg/l), observed and regressed (weight corrected) MoMs of ADAM12 were calculated. There was a significant difference in ADAM12 levels between Downs and controls during the pregnancy weeks 9 + 0 to 10 + 6, but not thereafter. By adding ADAM12 to the marker set used in the risk calculation program, one screening false negative Down syndrome case occurred in the affected population, which did not alter false positive rate. Adding ADAM12 as a parameter in Down screening did not cause radical changes in the risk value. The test might be useful at 9 and 10 weeks in which it might have the potential to improve the performance of the risk assessment especially for women receiving a result close to the high-risk cut-off. The real influence of ADAM12 remains to be elucidated in larger studies incorporating ADAM12 to the risk calculation program.

Patients with asymptomatic left ventricular systolic dysfunction (ALVSD) have an increased risk of heart failure (HF) and a worse life expectancy. Since valuable therapies may prevent such dismal evolution, screening programs for ALVSD have recently been advocated to detect as early as possible such ominous condition. Echocardiography represents the gold standard for the assessment of ALVSD but its indiscriminate use in screening programs is impractical. Clinical multivariate risk assessment associated with ECG and serum brain natriuretic peptide (BNP) may be a feasible strategy to screen ALVSD. We prospectively sought to investigate the feasibility and effectiveness of a screening program for ALVSD based on ECG and BNP used in a hierarchical sequence in patients at high risk for HF. Patients > or =55 years old with > or =2 risk factors for HF or > or =70 years old with > or =1 risk factor for HF entered the study performing sequentially ECG, BNP and echocardiographic evaluation. ALVSD was defined as a left ventricular ejection fraction < or =50%. Thirty-three of 122 enrolled patients (27%) had ALVSD. They were older, presented more frequently a history of chemotherapy exposure, had often bundle branch block and higher BNP levels. No patient without any major abnormalities (atrial fibrillation, left ventricular hypertrophy, STT alterations of ischemic/strain origin, pathologic Q wave, bundle branch block) on ECG (n=31, 24.4%) had ALVSD. Among the 91 patients with abnormal ECG, ALVSD was observed in 33 (36%). The area under the receiver operating characteristic curve to detect ALVSD by BNP was 0.86 (confidence interval 0.79-0.94, p<0.0001) and BNP values of > or =43 pg/ml showed a sensitivity and a specificity of 94% and 57%, respectively. The proposed screening program was able to identify 95% (31/33) of patients with ALVSD saving 53% of echocardiographic examinations with a substantial reduction of the costs to diagnose ALVSD. Our prospective investigation confirms that ECG and BNP may be useful in detecting ALVSD in high-risk patients. A cost-effective screening program based on such simple and low-cost diagnostic tests might be employed for the prevention of HF in primary and secondary prevention programs in high-risk patients.

When does mass screening for open neural tube defects in low-risk pregnancies result in cost savings?

1987-01-01

Using a decision analysis model, we estimated the savings that might be derived from a mass prenatal screening program aimed at detecting open neural tube defects (NTDs) in low-risk pregnancies. Our baseline analysis showed that screening v. no screening could be expected to save approximately $8 per pregnancy given a cost of $7.50 for the maternal serum alpha-feto-protein (MSAFP) test and a cost of $42,507 for hospital and rehabilitation services for the first 10 years of life for a child with spina bifida. When a more liberal estimate of the costs of caring for such a child was used, the savings with the screening program were more substantial. We performed extensive sensitivity analyses, which showed that the savings were somewhat sensitive to the cost of the MSAFP test and highly sensitive to the specificity (but not the sensitivity) of the test. A screening program for NTDs in low-risk pregnancies may result in substantial savings in direct health care costs if the screening protocol is followed rigorously and efficiently. PMID:2433011

To estimate the prevalence and referral rates in well born and high risk babies using two step hearing screening protocol with Distortion Product Otoacoustic Emissions (DPOAE) and Automated Auditory Brainstem Response (AABR). A prospective study was carried out on 1405 neonates (983 well born babies and 422 high risk babies) who were screened during May 2013 to January 2015 at Institute of Obstetrics and Gynecology, Madras Medical College, Chennai. All neonates were screened using two step screening protocol. They were initially tested with DPOAE. Referred babies in DPOAE were screened with AABR subsequently. Among 1405 (100%) neonates 983 (69.96%) were well born babies and 422 (30.03%) were high risk babies. Total referral rate in DPOAE was found to be 311 (22.13%) among which 195 (13.87%) were well born babies and 116 (8.25%) were high risk babies. Out of 311 babies 31 (2.20%) babies were referred in AABR screening. In 31 babies referred in AABR 11(0.78%) were from well born group and 20 (1.42%) were from the high risk group. Further diagnostic evaluation of these babies, 2 (0.14%) were confirmed to have hearing loss. This study reveals, the prevalence of congenital hearing loss in our population is 1.42 per 1000 babies. Using two step protocol especially AABR along with DPOAE at the initial level of testing significantly reduces referral rates in new born screening programs. Also AABR decreases the false positive responses hence increasing the efficiency of screening program. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Comparison of Cardiovascular Risk Screening Methods and Mortality Data among Hungarian Primary Care Population: Preliminary Results of the First Government-Financed Managed Care Program.

Besides participation in the primary prevention, screening as secondary prevention is an important requirement for primary care services. The effect of this work is influenced by the characteristics of individual primary care practices and doctors' screening habits, as well as by the regulation of screening processes and available financial resources. Between 1999 and 2009, a managed care program was introduced and carried out in Hungary, financed by the government. This financial support and motivation gave the opportunity to increase the number of screenings. 4,462 patients of 40 primary care practices were screened on the basis of SCORE risk assessment. The results of the screening were compared on the basis of two groups of patients, namely: those who had been pre-screened (pre-screening method) for known risk factors in their medical history (smoking, BMI, age, family cardiovascular history), and those randomly screened. The authors also compared the mortality data of participating primary care practices with the regional and national data. The average score was significantly higher in the pre-screened group of patients, regardless of whether the risk factors were considered one by one or in combination. Mortality was significantly lower in the participating primary practices than had been expected on the basis of the national mortality data. This government-financed program was a big step forward to establish a proper screening method within Hungarian primary care. Performing cardiovascular screening of a selected target group is presumably more appropriate than screening within a randomly selected population. Both methods resulted in a visible improvement in regional mortality data, though it is very likely that with pre-screening a more cost-effective selection for screening may be obtained.

To test a multimedia patient education program on colorectal cancer (CRC) screening that was designed specifically for the Hispanic/Latino community, and developed with input from community members. A total of 270 Hispanic/Latino adults, age 50-80 years, participated in Spanish for all phases of this pretest-posttest design. Patients were randomly assigned to a version of the multimedia program that opened with either a positive or negative introductory appeal. Structured interviews assessed screening relevant knowledge (anatomy and key terms, screening options, and risk information), past screening behavior, willingness to consider screening options, intention to discuss CRC screening with the doctor, and reactions to the multimedia patient education program. The multimedia program significantly increased knowledge of anatomy and key terms (e.g., polyp), primary screening options (FOBT, flexible sigmoidoscopy, colonoscopy), and risk information as well as willingness to consider screening (p<.001 for all). No significant differences emerged between positive and negative introductory appeals on these measures, intention to discuss CRC screening with their doctor, or rating the multimedia program. Multimedia tools developed with community input that are designed to present important health messages using graphics and audio can reach Hispanic/Latino adults across literacy levels and ethnic backgrounds. Additional research is needed to determine effects on actual screening behavior. Despite promising results for engaging a difficult-to-reach audience, the multimedia program should not be considered a stand-alone intervention or a substitute for communication with physicians. Rather, it is a priming mechanism intended to prepare patients for productive discussions of CRC screening.

Thalassemia screening program has been implemented for years in Southeast Asia, but no external quality assessment program has been established. We have developed and initiated the proficiency testing (PT) program for the first time in Thailand with the aim to assess the screening performance of laboratory staff and their competency in interpretation of the screening results. Three PT cycles per year were organized. From the first to the third cycle of the PT scheme, a total number of participant laboratories increased from 59 to 67. In each cycle, 2 PT items (assigned as blood samples of the couple) were provided. Performance evaluation was based on the accuracy of screening results, i.e . mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and the dichlorophenolindophenol (DCIP) test for haemoglobin E, including the competency in interpretation of screening results and assessment of foetal risk. Performance was assessed by comparing the participants' result against the assigned value. Of all 3 cycles, most laboratories reported acceptable MCV and MCH values. From the first to the third cycle, incorrect DCIP test and misinterpretation rates were decreased while incorrect risk assessment varied by cycle to cycle. Combining the accuracy of thalassemia screening and the competency in interpretation and risk assessment, approximately half of participants showed excellent performance. Improved performance observed in many laboratories reflects the achievement and benefit of the PT program which should be regularly provided.

The authors report on a method to calculate radiological risks, applicable to breast screening programs and other controlled medical exposures to ionizing radiation. In particular, it has been applied to make a risk assessment in the Valencian Breast Cancer Early Detection Program (VBCEDP) in Spain. This method is based on a parametric approach, through Markov processes, of hazard functions for radio-induced breast cancer incidence and mortality, with mean glandular breast dose, attained age and age-at-exposure as covariates. Excess relative risk functions of breast cancer mortality have been obtained from two different case-control studies exposed to ionizing radiation, with different follow-up time: the Canadian Fluoroscopy Cohort Study (1950-1987) and the Life Span Study (1950-1985 and 1950-1990), whereas relative risk functions for incidence have been obtained from the Life Span Study (1958-1993), the Massachusetts tuberculosis cohorts (1926-1985 and 1970-1985), the New York post-partum mastitis patients (1930-1981) and the Swedish benign breast disease cohort (1958-1987). Relative risks from these cohorts have been transported to the target population undergoing screening in the Valencian Community, a region in Spain with about four and a half million inhabitants. The SCREENRISK software has been developed to estimate radiological detriments in breast screening. Some hypotheses corresponding to different screening conditions have been considered in order to estimate the total risk associated with a woman who takes part in all screening rounds. In the case of the VBCEDP, the total radio-induced risk probability for fatal breast cancer is in a range between [5 × 10-6, 6 × 10-4] versus the natural rate of dying from breast cancer in the Valencian Community which is 9.2 × 10-3. The results show that these indicators could be included in quality control tests and could be adequate for making comparisons between several screening programs.

The aim of this study was to determine if handgrip strength (HGS) is a predictor of nutritional risk in community-dwelling older adults. A cross-sectional study was carried out to determine the relationship between HGS and nutritional risk using SCREEN 1. The setting was Congregate Nutrition program meal sites (n = 10) in North Central Florida and included community-dwelling older adults participating in the Congregate Nutrition program. Older adults (n = 136; 77.1 ± 8.9 y; 45 M, 91 F) participated in the study. Nutritional risk was identified in 68% of participants, with 10% exhibiting clinically relevant weakness (men, HGS < 26 kg; women, HGS < 16 kg), suggesting a vulnerable population. HGS was weakly associated with nutritional risk as assessed by SCREEN 1 (AUC = 0.59), but alternate cutpoints, 33 kg for men (mean of both hands) and 22 kg for women (highest of either hand), provided the best comparison to nutritional risk. In community-dwelling older adults, HGS was weakly associated with nutritional risk assessed using traditional screening. However, as existing research supports the inclusion of HGS in malnutrition screening in acute care, further research into the usefulness of HGS and possibly other measures of functional status in nutrition risk screening of community-dwelling older adults may be warranted.

Widespread lung cancer screening with low-dose computed tomography is urgently needed in Europe to identify lung cancers early and reduce lung cancer deaths. The most effective method of identifying high-risk individuals and recruiting them for screening has not been determined. In the present pilot study we investigated direct telephoning to families as a way of identifying high risk individuals and recruiting them to a screening/smoking cessation program, that avoided the selection bias of voluntary screening. Families in the province of Milan, Italy, were contacted by telephone at their homes and asked about family members over 50 years who were heavy smokers (30 or more pack-years). Persons meeting these criteria were contacted and asked to participate in the program. Those who agreed were given an appointment to undergo screening and receive smoking cessation counseling. Among the 1000 contacted families, involving 2300 persons, 44 (1.9%) were eligible for LDCT screening, and 12 (27%) of these participated in the program. The cost of this recruitment strategy pilot study was around 150 euro per screened subject. We obtained useful information on the proportion of the general population eligible for lung cancer screening and the proportion of those who responded. However the cost of home telephone calling is probably too high to be practicable as a method of recruiting high risk persons for screening. Alternative recruitment methods, possibly involving family physicians practitioners, need to be investigated. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Background Screening by fecal occult blood test and lower endoscopy have lowered colorectal cancer (CRC) mortality, but compliance gaps persist. Of concern are possible disparities in uptake of CRC screening between White and African American (AA) men. Our goal was to assess for disparities in uptake of CRC screening among men participating in a high-risk prostate cancer clinic. If present, such disparities could support hypotheses for further research examining racial differences in awareness and patient preferences in undergoing CRC screening. Methods Baseline data on a racially diverse cohort of men age 50–69 at increased risk of prostate cancer collected via the prostate cancer risk assessment program (PRAP) at Fox Chase Cancer Center were analyzed. Predictors of uptake of CRC screening were assessed using multivariable logistic regression. Results Compared to Whites, AA men had statistically significantly lower uptake of fecal occult blood testing (AA 49.0% vs White 60.7%, p=0.035), lower endoscopy (AA 44.1% vs White 58.5%, p=0.011), and any CRC screening (AA 66.2% vs White 76.3%, p=0.053). Predictors of uptake of lower endoscopy among AA men included older age (OR 3.61, 95% CI 1.87–6.97), family history of CRC (OR 3.47, 95% CI 1.30–9.25), and insurance status (OR 1.90, 95% CI 1.04–3.46). Conclusion Despite awareness of cancer risk and motivation to seek prostate cancer screening through a specialized prostate cancer risk assessment program, evidence supporting compliance gaps with CRC screening among men was found. Tailored messages to younger AA men with and without a family history of CRC are needed. PMID:21751189

Radiation risks in lung cancer screening programs: a comparison with nuclear industry workers and atomic bomb survivors.

PubMed

McCunney, Robert J; Li, Jessica

2014-03-01

The National Lung Cancer Screening Trial (NLST) demonstrated that screening with low-dose CT (LDCT) scan reduced lung cancer and overall mortality by 20% and 7%, respectively. The LDCT scanning involves an approximate 2-mSv dose, whereas full-chest CT scanning, the major diagnostic study used to follow up nodules, may involve a dose of 8 mSv. Radiation associated with CT scanning and other diagnostic studies to follow up nodules may present an independent risk of lung cancer. On the basis of the NLST, we estimated the incidence and prevalence of nodules detected in screening programs. We followed the Fleischner guidelines for follow-up of nodules to assess cumulative radiation exposure over 20- and 30-year periods. We then evaluated nuclear worker cohort studies and atomic bomb survivor studies to assess the risk of lung cancer from radiation associated with long-term lung cancer screening programs. The findings indicate that a 55-year-old lung screening participant may experience a cumulative radiation exposure of up to 280 mSv over a 20-year period and 420 mSv over 30 years. These exposures exceed those of nuclear workers and atomic bomb survivors. This assessment suggests that long-term (20-30 years) LDCT screening programs are associated with nontrivial cumulative radiation doses. Current lung cancer screening protocols, if conducted over 20- to 30-year periods, can independently increase the risk of lung cancer beyond cigarette smoking as a result of cumulative radiation exposure. Radiation exposures from LDCT screening and follow-up diagnostic procedures exceed lifetime radiation exposures among nuclear power workers and atomic bomb survivors.

British Columbia undertook a colorectal cancer screening pilot program in 3 communities. Our objective was to assess the performance of 2-specimen fecal immunochemical testing in the detection of colorectal neoplasms in this population-based screening program. A prospective cohort of asymptomatic, average-risk people aged 50 to 74 years completed 2 quantitative fecal immunochemical tests every 2 years, with follow-up colonoscopy if the result of either test was positive. Participant demographics, fecal immunochemical test results, colonoscopy quality indicators and pathology results were recorded. Non-screen-detected colorectal cancer that developed in program participants was identified through review of data from the BC Cancer Registry. A total of 16 234 people completed a first round of fecal immunochemical testing, with a positivity rate of 8.6%; 5378 (86.0% of eligible participants) completed a second round before the end of the pilot program, with a positivity rate of 6.7%. Of the 1756 who had a positive test result, 1555 (88.6%) underwent colonoscopy. The detection rate of colorectal cancer was 3.5 per 1000 participants. The positive predictive value of the fecal immunochemical test was 4.9% (95% confidence interval [CI] 3.8%-6.0%) for colorectal cancer, 35.0% (95% CI 32.5%-37.2%) for high-risk polyps and 62.0% (95% CI 59.6%-64.4%) for all neoplasms. The number needed to screen was 283 to detect 1 cancer, 40 to detect 1 high-risk polyp and 22 to detect any neoplasm. Screening every 2 years with a 2-specimen fecal immunochemical test surpassed the current benchmark for colorectal cancer detection in population-based screening. This study has implications for other jurisdictions planning colorectal cancer screening programs.

Kindler, H

2010-10-01

Selective primary prevention programs for child abuse and neglect depend on risk screening instruments that have the goal of systematically identifying families who can profit most from early help. Based on a systematic review of longitudinal studies, a set of established risk factors for early child abuse and neglect is presented. Nearly half of the items included in screening instruments can be seen as validated. Available studies indicate a high sensitivity of risk screening instruments. Positive predictive values, however, are low. Overall, the use of risk screening instruments in the area of primary prevention for families at risk represents a feasible method, as long as stigmatizing effects can be avoided and participating families also benefit beyond preventing endangerment.

Creation of a National, At-home Model for Ashkenazi Jewish Carrier Screening.

2015-06-01

Ethnicity-based carrier screening for the Ashkenazi Jewish population has been available and encouraged by advocacy and community groups since the early 1970's. Both the American College of Medical Genetics and the American Congress of Obstetricians and Gynecologists recommend carrier screening for this population (Obstetrics and Gynecology, 114(4), 950-953, 2009; Genetics in Medicine, 10(1), 55-56, 2008). While many physicians inquire about ethnic background and offer appropriate carrier screening, studies show that a gap remains in implementing recommendations (Genetic testing and molecular biomarkers, 2011). In addition, education and outreach efforts targeting Jewish communities have had limited success in reaching this at-risk population. Despite efforts by the medical and Jewish communities, many Jews of reproductive age are not aware of screening, and remain at risk for having children with preventable diseases. Reaching this population, preferably pre-conception, and facilitating access to screening is critically important. To address this need, genetic counselors at Emory University developed JScreen, a national Jewish genetic disease screening program. The program includes a national marketing and PR campaign, online education, at-home saliva-based screening, post-test genetic counseling via telephone or secure video conferencing, and referrals for face-to-face genetic counseling as needed. Our goals are to create a successful education and screening program for this population and to develop a model that could potentially be used for other at-risk populations.

To explore the performance of a protocol combining fecal immunochemical test (FIT) and a high-risk factor questionnaire (HRFQ) for selecting patients requiring colonoscopy as part of a population-based colorectal cancer (CRC) screening program in China. From 2015 to 2016, we conducted a CRC screening program for all residents aged 45 years or older in Tianhe District, Guangzhou City, China. Participants underwent an FIT and received an HRFQ as part of primary screening. Those with positive FIT and/or HRFQ results were considered to be at high risk and were recommended to undergo colonoscopy. A total of 10 074 subjects were recruited and enrolled in the screening program. In the enrolled population, 17.5% had positive FIT results and 19.4% had positive HRFQ results. Of those recommended to undergo diagnostic colonoscopy, 773 did so. The screening method's overall positive predictive value (PPV) was 4.9% for non-adenomatous polyps, 11.4% for low-risk adenomas (LRAs), 15.9% for high-risk adenomas (HRAs) and 1.6% for CRC. The PPVs of positive FIT results for non-adenomatous polyps, LRAs, HRAs and CRC were 5.2%, 15.9%, 22.5% and 2.5%, respectively. The PPVs of positive HRFQ results for non-adenomatous polyps, LRA, HRA and CRC were 4.1%, 10.2%, 14.3% and 1.4%, respectively. The PPVs associated with combined positive FIT and HRFQ results for non-adenomatous polyps, LRAs, HRAs and CRC were 4.5%, 16.4%, 23.7% and 2.8%, respectively. Our results suggest that this two-step CRC screening strategy, involving a combination of FIT and HRFQ followed by colonoscopy, is useful to identify early-stage CRC. The high detection rates and PPVs for CRC and adenomas encourage this strategy's use in ongoing screening programs.

Electronic health-records (EHR) are increasingly used by epidemiologists studying disease following surveillance testing to provide evidence for screening intervals and referral guidelines. Although cost-effective, undiagnosed prevalent disease and interval censoring (in which asymptomatic disease is only observed at the time of testing) raise substantial analytic issues when estimating risk that cannot be addressed using Kaplan-Meier methods. Based on our experience analysing EHR from cervical cancer screening, we previously proposed the logistic-Weibull model to address these issues. Here we demonstrate how the choice of statistical method can impact risk estimates. We use observed data on 41,067 women in the cervical cancer screening program at Kaiser Permanente Northern California, 2003-2013, as well as simulations to evaluate the ability of different methods (Kaplan-Meier, Turnbull, Weibull and logistic-Weibull) to accurately estimate risk within a screening program. Cumulative risk estimates from the statistical methods varied considerably, with the largest differences occurring for prevalent disease risk when baseline disease ascertainment was random but incomplete. Kaplan-Meier underestimated risk at earlier times and overestimated risk at later times in the presence of interval censoring or undiagnosed prevalent disease. Turnbull performed well, though was inefficient and not smooth. The logistic-Weibull model performed well, except when event times didn't follow a Weibull distribution. We have demonstrated that methods for right-censored data, such as Kaplan-Meier, result in biased estimates of disease risks when applied to interval-censored data, such as screening programs using EHR data. The logistic-Weibull model is attractive, but the model fit must be checked against Turnbull non-parametric risk estimates. Copyright © 2017 The Authors. Published by Elsevier Inc.

In recent years, risk stratification has sparked interest as an innovative approach to disease screening and prevention. The approach effectively personalizes individual risk, opening the way to screening and prevention interventions that are adapted to subpopulations. The international perspective project, which is developing risk stratification for breast cancer, aims to support the integration of its screening approach into clinical practice through comprehensive tool-building. Policies and guidelines for risk stratification—unlike those for population screening programs, which are currently well regulated—are still under development. Indeed, the development of guidelines for risk stratification reflects the translational aspects of perspective. Here, we describe the risk stratification process that was devised in the context of perspective, and we then explain the consensus-based method used to develop recommendations for breast cancer screening and prevention in a risk-stratification approach. Lastly, we discuss how the recommendations might affect current screening policies. PMID:28050152

Mobile applications (apps) are promising tools to support chronic disease screening and linkage to health services. They have the potential to increase healthcare access for vulnerable populations. The HealthNavigator app was developed to provide chronic disease risk assessments, linkage to local general practitioners (GPs) and lifestyle programs, and a personalised health report for discussion with a GP. Assessments were either self-administered or facilitated by community health workers through a Primary Health Network (PHN) initiative targeting ethnically diverse communities. In total, 1492 assessments (80.4% self-administered, 19.6% facilitated) were conducted over a 12-month period in Queensland, Australia. Of these, 26% of people screened came from postcodes representing the lowest quartile of socioeconomic disadvantage. When compared against self-administered assessments, subjects screened by the facilitated program were more likely to be born outside Australia (80.5 v. 33.2%, P<0.001), and to fall within a high risk category based on cardiovascular risk scores (19.8 v. 13.7%, P<0.01) and type 2 diabetes mellitus risk scores (58.0 v. 40.1%, P<0.001). Mobile apps embedded into PHN programs may be a useful adjunct for the implementation of community screening programs. Further research is needed to determine their effect on health service access and health outcomes.

The objective of this study was to acquire process information, clinician and client feedback during implementation of a routine suicide risk screening program for outpatients with serious mental disorders. We studied implementation of a suicide-screening tool in a large public mental health outpatient facility in New York City. Most clinical staff who provided an opinion indicated screening was useful, feasible and helpful; most clients did not mind screening. Facilitators to program implementation included administrative support and ease of use. Barriers included consent, misperceptions, and concerns regarding potential liability. It is feasible to implement a suicide-screening tool in a public outpatient clinic. However, even experienced clinicians harbor unfounded myths. Effective large scale use will require vigorous training and oversight. PMID:19363752

Objective To define the risk factors for hearing loss in infants (aged 3 months) under universal hearing screening program. Materials and methods A total of 3,120 infants (aged 3 months) who underwent hearing screening using a universal hearing screening program using automated otoacoustic emission test between November 1, 2010 and May 31, 2012 in Uttaradit Hospital, Buddhachinaraj Hospital, and Sawanpracharuk Hospital (tertiary hospitals) located in Northern Thailand were included in this prospective cohort study. Results Of the 3,120 infants, 135 (4.3%) were confirmed to have hearing loss with the conventional otoacoustic emission test. Five of these 135 infants (3.7%) with hearing loss showed test results consistent with auditory brainstem responses. From the univariable analysis, there were eleven potential risk factors associated with hearing deterioration. On multivariable analysis, the risk factors independently associated with hearing loss at 3 months were birth weight 1,500–2,500 g (risk ratio [RR] 1.6, 95% confidence interval [CI] 1.1–2.6), APGAR score <6 at 5 minutes (RR 2.2, 95% CI 1.1–4.4), craniofacial anomalies (RR 2.5, 95% CI 1.6–4.2), sepsis (RR 1.8, 95% CI 1.0–3.2), and ototoxic exposure (RR 4.1, 95% CI 1.9–8.6). Conclusion This study concluded that low birth weight, APGAR score <6 at 5 minutes, craniofacial anomalies, sepsis, and ototoxic exposure are the risk factors for bilateral hearing loss in infants (aged 3 months) and proper tests should be performed to identify these risk factors. As an outcome, under the present circumstances, it is suggested that infirmary/physicians/general practitioners/health action centers/polyclinics should carry out universal hearing screening in all infants before 36 weeks. The public health policy of Thailand regarding a universal hearing screening program is important for the prevention of disability and to enhance people’s quality of life. PMID:26766912

A program for the prevention of major hemoglobinopathies was initiated in 2008 in the Kurdistan region of Iraq. This study reports on the achievements and challenges of the program. A total of 102,554 individuals (51,277 couples) visiting a premarital center between 2008 and 2012 were screened for carrier status of hemoglobinopathies, and at-risk couples were counseled. A total of 223 (4.3/1,000) couples were identified and counseled as high-risk couples. Available data on 198 high-risk couples indicated that 90.4% proceeded with their marriage plans, and 15% of these married couples decided to have prenatal diagnosis (PND) in subsequent pregnancies with the identification of 8 affected fetuses; all were terminated as chosen by the parents. Thirty affected births were recorded among the high-risk couples. The premarital program managed to reduce the affected birth rate of major hemoglobinopathies by 21.1%. Of the 136 affected babies born during the study period, 77.9% were born to couples married prior to the start of the program, while 22.1% were born to couples identified as having a high risk. The main reason for not taking the option of PND was unaffordable costs. Financial support would have increased opting for PND by high-risk couples. Further reduction in affected birth rates could be achieved by including parallel antenatal screening programs to cover those married before the initiation of the premarital program and improving the public health education and counseling programs. © 2015 S.

Breast magnetic resonance imaging (MRI) screening of women under 50 years old at high familial risk of breast cancer was given interim funding by Medicare in 2009 on the basis that a review would be undertaken. An updated literature review has been undertaken by the Medical Services Advisory Committee but there has been no assessment of the quality of the screening or other screening outcomes. This review examines the evidence basis of breast MRI screening and how this fits within an Australian context with the purpose of informing future modifications to the provision of Medicare-funded breast MRI screening in Australia.more » Issues discussed will include selection of high-risk women, the options for MRI screening frequency and measuring the outcomes of screening.« less

The Risk-stratified Osteoporosis Strategy Evaluation (ROSE) study investigated the effectiveness of a two-step screening program for osteoporosis in women. We found no overall reduction in fractures from systematic screening compared to the current case-finding strategy. The group of moderate- to high-risk women, who accepted the invitation to DXA, seemed to benefit from the program. The purpose of the ROSE study was to investigate the effectiveness of a two-step population-based osteoporosis screening program using the Fracture Risk Assessment Tool (FRAX) derived from a self-administered questionnaire to select women for DXA scan. After the scanning, standard osteoporosis management according to Danish national guidelines was followed. Participants were randomized to either screening or control group, and randomization was stratified according to age and area of residence. Inclusion took place from February 2010 to November 2011. Participants received a self-administered questionnaire, and women in the screening group with a FRAX score ≥ 15% (major osteoporotic fractures) were invited to a DXA scan. Primary outcome was incident clinical fractures. Intention-to-treat analysis and two per-protocol analyses were performed. A total of 3416 fractures were observed during a median follow-up of 5 years. No significant differences were found in the intention-to-treat analyses with 34,229 women included aged 65-80 years. The per-protocol analyses showed a risk reduction in the group that underwent DXA scanning compared to women in the control group with a FRAX ≥ 15%, in regard to major osteoporotic fractures, hip fractures, and all fractures. The risk reduction was most pronounced for hip fractures (adjusted SHR 0.741, p = 0.007). Compared to an office-based case-finding strategy, the two-step systematic screening strategy had no overall effect on fracture incidence. The two-step strategy seemed, however, to be beneficial in the group of women who were identified by FRAX as moderate- or high-risk patients and complied with DXA.

To study the cost-effectiveness of high-resolution microendoscopy (HRME) in an esophageal squamous cell carcinoma (ESCC) screening program in China. A decision analytic Markov model of ESCC was developed. Separate model analyses were conducted for cohorts consisting of an average-risk population or a high-risk population in China. Hypothetical 50-year-old individuals were followed until age 80 or death. We compared three different strategies for both cohorts: (1) no screening; (2) standard endoscopic screening with Lugol's iodine staining; and (3) endoscopic screening with Lugol's iodine staining and an HRME. Model parameters were estimated from the literature as well as from GLOBOCAN, the Cancer Incidence and Mortality Worldwide cancer database. Health states in the model included non-neoplasia, mild dysplasia, moderate dysplasia, high-grade dysplasia, intramucosal carcinoma, operable cancer, inoperable cancer, and death. Separate ESCC incidence transition rates were generated for the average-risk and high-risk populations. Costs in Chinese currency were converted to international dollars (I$) and were adjusted to 2012 dollars using the Consumer Price Index. The main outcome measurements for this study were quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER). For the average-risk population, the HRME screening strategy produced 0.043 more QALYs than the no screening strategy at an additional cost of I$646, resulting in an ICER of I$11808 per QALY gained. Standard endoscopic screening was weakly dominated. Among the high-risk population, when the HRME screening strategy was compared with the standard screening strategy, the ICER was I$8173 per QALY. For both the high-risk and average-risk screening populations, the HRME screening strategy appeared to be the most cost-effective strategy, producing ICERs below the willingness-to-pay threshold, I$23500 per QALY. One-way sensitivity analysis showed that, for the average-risk population, higher specificity of Lugol's iodine (> 40%) and lower specificity of HRME (< 70%) could make Lugol's iodine screening cost-effective. For the high-risk population, the results of the model were not substantially affected by varying the follow-up rate after Lugol's iodine screening, Lugol's iodine test characteristics (sensitivity and specificity), or HRME specificity. The incorporation of HRME into an ESCC screening program could be cost-effective in China. Larger studies of HRME performance are needed to confirm these findings.

Community-Based Multidisciplinary Computed Tomography Screening Program Improves Lung Cancer Survival.

2016-05-01

Lung cancer is the most common cause of cancer deaths in the United States. Overall survival is less than 20%, with the majority of patients presenting with advanced disease. The National Lung Screening Trial, performed mainly in academic medical centers, showed that cancer mortality can be reduced with computed tomography (CT) screening compared with chest radiography in high-risk patients. To determine whether this survival advantage can be duplicated in a community-based multidisciplinary thoracic oncology program, we initiated a CT scan screening program for lung cancer within an established health care system. In 2008, we launched a lung cancer CT screening program within the WellStar Health System (WHS) consisting of five hospitals, three health parks, 140 outpatient medical offices, and 12 imaging centers that provide care in a five-county area of approximately 1.4 million people in Metro-Atlanta. Screening criteria incorporated were the International Early Lung Cancer Action Program (2008 to 2010) and National Comprehensive Cancer Network guidelines (2011 to 2013) for moderate- and high-risk patients. A total of 1,267 persons underwent CT lung cancer screening in WHS from 2008 through 2013; 53% were men, 87% were 50 years of age or older, and 83% were current or former smokers. Noncalcified indeterminate pulmonary nodules were found in 518 patients (41%). Thirty-six patients (2.8%) underwent a diagnostic procedure for positive findings on their CT scan; 30 proved to have cancer, 28 (2.2%) primary lung cancer and 2 metastatic cancer, and 6 had benign disease. Fourteen patients (50%) had their lung cancer discovered on their initial CT scan, 11 on subsequent scans associated with indeterminate pulmonary nodules growth and 3 patients who had a new indeterminate pulmonary nodules. Only 15 (54%) of these 28 patients would have qualified as a National Lung Screening Trial high-risk patient; 75% had stage I or II disease. Overall 5-year survival was 64% and 5-year cancer specific survival was 71% in the screened patients, whereas nonscreened lung cancer patients during that time in WHS had an overall survival of only 19% (p < 0.001). A community-based multidisciplinary lung cancer screening program can improve survival of patients with lung cancer outside of a large multicenter study. This survival advantage was caused by a significant stage shift to earlier disease. Lung cancer CT screening may also benefit patients not meeting the National Lung Screening Trial criteria who are at moderate or high risk for lung cancer.

2007-07-31

OBJECTIVES The Northeast Regional Cancer Institute is conducting a program of ongoing epidemiologic research to address cancer disparities in northeast Pennsylvania. Of particular concern are disparities in the incidence of, stage at diagnosis, and mortality from colorectal cancer. In northeast Pennsylvania, age-adjusted incidence and mortality rates for colorectal cancer are higher, and a significantly smaller proportion of new colorectal cancer cases are diagnosed with local stage disease than is observed in comparable national data. Further, estimates of the prevalence of colorectal cancer screening in northeast Pennsylvania are lower than the US average. The Northeast Regional Cancer Institute’s research program supportsmore » surveillance of common cancers, investigations of cancer risk factors and screening behaviors, and the development of resources to further cancer research in this community. This project has the following specific objectives: I. To conduct cancer surveillance in northeast Pennsylvania. a. To monitor incidence and mortality for all common cancers, and colorectal cancer, in particular, and b. To document changes in the stage at diagnosis of colorectal cancer in this high-risk, underserved community. II. To conduct a population-based study of cancer risk factors and screening behavior in a six county region of northeast Pennsylvania. a. To monitor and document changes in colorectal cancer screening rates, and b. To document the prevalence of cancer risk factors (especially factors that increase the risk of colorectal cancer) and to identify those risk factors that are unusually common in this community. APPROACH Cancer surveillance was conducted using data from the Northeast Regional Cancer Institute’s population-based Regional Cancer Registry, the Pennsylvania Cancer Registry, and NCI’s SEER program. For common cancers, incidence and mortality were examined by county within the region and compared to data for similar populations in the US. For colorectal cancer, the stage at diagnosis of cases diagnosed in northeast Pennsylvania was compared to data from prior years. A population-based interview study of healthy adults was conducted to document the status of cancer screening and to estimate the prevalence of established cancer risk factors in this community. This study is similar in design to that used by the Centers for Disease Control and Prevention’s (CDC) Behavioral Risk Factor Surveillance System (BRFSS). EXPERIMENTAL METHODS AND PROCEDURES: This program includes two distinct but related projects. The first project uses existing data to conduct cancer surveillance in northeast Pennsylvania, and the second is a population-based study of cancer risk factors and cancer screening behaviors in this same population. HUMAN SUBJECTS CONSIDERATIONS This program includes two projects: cancer surveillance and a population-based study of cancer risk factors and screening behavior. The cancer surveillance project involves only the use of existing aggregate data or de-identified data. As such, the surveillance project is exempt from human subjects considerations. The study of cancer risk factors and screening behaviors includes data from a random sample of adult residents of northeast Pennsylvania who are 18 or more years of age. All races, ethnicities and both sexes are included in proportion to their representation in the population. Subjects are interviewed anonymously by telephone; those who are unable to complete an interview in English are ineligible. This project has been reviewed and approved by the Scranton-Temple Residency Program IRB (IRB00001355), which is the IRB for the Northeast Regional Cancer Institute.« less

A Cost-Utility Analysis of Lung Cancer Screening and the Additional Benefits of Incorporating Smoking Cessation Interventions

PubMed Central

Villanti, Andrea C.; Jiang, Yiding; Abrams, David B.; Pyenson, Bruce S.

2013-01-01

Background A 2011 report from the National Lung Screening Trial indicates that three annual low-dose computed tomography (LDCT) screenings for lung cancer reduced lung cancer mortality by 20% compared to chest X-ray among older individuals at high risk for lung cancer. Discussion has shifted from clinical proof to financial feasibility. The goal of this study was to determine whether LDCT screening for lung cancer in a commercially-insured population (aged 50–64) at high risk for lung cancer is cost-effective and to quantify the additional benefits of incorporating smoking cessation interventions in a lung cancer screening program. Methods and Findings The current study builds upon a previous simulation model to estimate the cost-utility of annual, repeated LDCT screenings over 15 years in a high risk hypothetical cohort of 18 million adults between age 50 and 64 with 30+ pack-years of smoking history. In the base case, the lung cancer screening intervention cost $27.8 billion over 15 years and yielded 985,284 quality-adjusted life years (QALYs) gained for a cost-utility ratio of $28,240 per QALY gained. Adding smoking cessation to these annual screenings resulted in increases in both the costs and QALYs saved, reflected in cost-utility ratios ranging from $16,198 per QALY gained to $23,185 per QALY gained. Annual LDCT lung cancer screening in this high risk population remained cost-effective across all sensitivity analyses. Conclusions The findings of this study indicate that repeat annual lung cancer screening in a high risk cohort of adults aged 50–64 is highly cost-effective. Offering smoking cessation interventions with the annual screening program improved the cost-effectiveness of lung cancer screening between 20% and 45%. The cost-utility ratios estimated in this study were in line with other accepted cancer screening interventions and support inclusion of annual LDCT screening for lung cancer in a high risk population in clinical recommendations.

To assess the prostate cancer screening practices in Rhode Island, we designed a questionnaire which was sent to 150 primary care physicians. A population-based survey was distributed to 194 men over 40 asking about screening history and risk factors. Eighty-five percent of primary care physicians reported performing annual prostate-specific antigen tests (PSAs) and digital rectal exams, 63% recognized family history as a risk factor, and 14% identified African Americans as a high-risk population. The survey found that 48% of men recognized family history as a risk factor and 6% understood that African Americans were at high risk. Each year, 200 men, primarily SED, are invited to a PawSox baseball game where physicians provide information on prostate cancer risk, treatment options, and outcomes. Free PSAs are provided. The questionnaire and survey demonstrate a need for more public education regarding prostate cancer in high-risk populations. Tailored community-based interventions, such as the Pawsox & Prostate program, can be effective professional and public education strategies to increase screening in high-risk populations.

In Tunisia, cervical cancer is considered the second leading cancer in women and causes high morbidity and mortality. This study aimed to investigate women's knowledge, attitudes, and practices of cervical cancer screening in the region of Monastir (Tunisia). We conducted a cross-sectional study exploring the cervical cancer screening knowledge, attitudes, and practices of women in the region of Monastir. The study was conducted in health centers in this region from 1st March to 30th June 2009. Data were collected using a structured questionnaire containing 15 items on demographic status, knowledge of risk factors and screening methods, and attitudes toward the relevance and effectiveness of cervical cancer screening. A total of 900 women agreed to take part in the study. Their mean age was 41.6±12.4 years and 64% did not exceed the primary level of education. According to the constructed scores, 22.8% of the participants had good knowledge of cervical cancer risk factors and 38.2% had good knowledge of screening methods. Multiple logistic regression analysis showed that women aged 45 and older, married, with good knowledge of risk factors and screening methods were more likely to undergo cervical cancer screening (P-value<0.01). This study provides useful information that could be utilized by both researchers and those involved in public health programs. The results show the need for educational programs to enhance women's adherence to cervical cancer screening programs in Tunisia. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Although public health practitioners commonly use community education and outreach events to promote cancer screening, the effectiveness of this strategy remains unclear. This study evaluated 23 outreach events, conducted as part of the Georgia Colorectal Cancer Control Program. Of the estimated 1778 individuals who attended these events, those ages 50-75 were eligible to participate in a telephone survey 3 months after attending an event. Surveys measured colorectal cancer (CRC) risk status, CRC screening history at the time of the event, seeking or obtaining CRC screening at 3-month follow-up, and participants' knowledge of their CRC screening status. Of the 335 individuals contacted for this evaluation, 185 completed the survey. Eighty participants (43.2 %) were at elevated risk for CRC and 99 participants (53.5 %) were at average risk. Of the 99 average-risk participants, the majority (n = 69) were not due for CRC screening at the time they attended an event because they had previously received screening within the recommended time intervals. Thirty average-risk participants were due for CRC screening, either because they had never been screened before (n = 19) or because they were due for rescreening (n = 11). Approximately half of these 30 participants who were due for screening either sought (n = 6, 20.0 %) or obtained screening (n = 8, 26.7 %) 3 months following the event. Community education and outreach events may play an important role in motivating participants to seek or obtain CRC screening, but unless priority audiences are identified and recruited, events may attract people who are already compliant with CRC screening.

Cervical cancer is a highly preventable disease that disproportionately affects women in developing countries and women with HIV. As integrated HIV and cervical cancer screening programs in Sub-Saharan Africa mature, we have an opportunity to measure the impact of outreach and education efforts and identify areas for future improvement. We conducted a cross-sectional survey of 106 women enrolled in care at an integrated HIV clinic in the Nyanza Province of Kenya 5 years after the start of a cervical cancer screening program. Female clinic attendees who met clinic criteria for cervical cancer screening were asked to complete an oral questionnaire assessing their cervical cancer knowledge, attitudes, and screening history. Ninety-nine percent of women had heard of screening, 70 % felt at risk, and 84 % had been screened. Increased duration of HIV diagnosis was associated with feeling at risk and with a screening history. Nearly half (48 %) of women said they would not get screened if they had to pay for it.

Lung cancer screening with annual chest computed tomography (CT) is recommended for current and former smokers with a ≥30-pack-year smoking history. Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of developing lung cancer and may benefit from screening at lower pack-year thresholds. We used a previously validated simulation model to compare the health benefits of lung cancer screening in current and former smokers ages 55-80 with ≥30 pack-years with hypothetical programs using lower pack-year thresholds for individuals with COPD (≥20, ≥10, and ≥1 pack-years). Calibration targets for COPD prevalence and associated lung cancer risk were derived using the Framingham Offspring Study limited data set. We performed sensitivity analyses to evaluate the stability of results across different rates of adherence to screening, increased competing mortality risk from COPD, and increased surgical ineligibility in individuals with COPD. The primary outcome was projected life expectancy. Programs using lower pack-year thresholds for individuals with COPD yielded the highest life expectancy gains for a given number of screens. Highest life expectancy was achieved when lowering the pack-year threshold to ≥1 pack-year for individuals with COPD, which dominated all other screening strategies. These results were stable across different adherence rates to screening and increases in competing mortality risk for COPD and surgical ineligibility. Current and former smokers with COPD may disproportionately benefit from lung cancer screening. A lower pack-year threshold for screening eligibility may benefit this high-risk patient population. © 2015 American Cancer Society.

The literature on diabetes mellitus in the South Asian population clearly states the high-risk status of this group, yet there is a lack of effective models of culturally relevant, community-based screening and education programs for such a group. The South Asian Diabetes Prevention Program (SADPP) was developed to enhance equitable access to diabetes prevention resources for the South Asian communities in Toronto by offering language-specific and culturally relevant services. The SADPP model works through 3 participant education sessions plus an additional attachment and enrolment component. The screening tool that SADPP uses to provide participants with their individual risk score at the first education session is derived from the multiculturally validated Canadian Diabetes Risk Assessment Questionnaire (CANRISK), which has been modified to reflect the distinctive characteristics of the South Asian population. After analyzing the risk scores, 32% of participants were at increased risk, 40% were at high risk, 21% were at very high risk and only 7% were found to be at low risk of diabetes development. Evaluations of the program conducted in 2010 and 2013 revealed that the program is achieving its objectives and that participants increase their knowledge and self-efficacy related to diabetes prevention after program participation. Participants reported that the presentation from the nurse and dietitian, the question-and-answer time, the healthy eating demonstration, the multiple languages of delivery and the convenient location were especially beneficial. Those working in the field are encouraged to adapt this model and to contribute to the development of culturally relevant, community-driven diabetes prevention programs.

With the aim of developing more efficient gastric cancer screening programs for use in Japan, we studied a new screening program that combines serum pepsinogen (PG) testing and barium digital radiography (DR). A total of 17 647 middle-aged male subjects underwent workplace screening over a 7-year period using a combination of PG testing and DR. This program's effectiveness, as well as other characteristics of the program, was analyzed. Forty-nine cases of gastric cancer were detected (comprising 88% early cancer cases). The detection rate was 0.28%, and the positive predictive value was 0.85%. The PG test detected 63.3% of cases, DR detected 69.4% of cases, and both tests were positive in 32.7% of cancer cases. The two methods were almost equally effective, and were considerably more effective than conventional screening using photofluorography. Each screening method detected a distinct gastric cancer subgroup; the PG test efficiently detected asymptomatic small early cancer with intestinal type histology, while DR was efficient at detecting cancers with depressed or ulcerated morphology and diffuse type histology. The cost for the detection of a single cancer was much less than that for conventional screening. In fact, it is possible to further reduce the cost of detecting a single cancer to a cost comparable to that of surgically resecting a single gastric cancer. Thus, it is probable that a highly efficient gastric cancer screening system can be implemented by combining the two screening methods. Such a screening program would be beneficial in a population at high risk for gastric cancer.

Our need to create a program for individuals at high risk for breast cancer development led us to research the available data on such programs. In this paper, we summarize our findings and our thinking process as we developed our own program. Breast cancer incidence is increasing worldwide. Even though there are known risk factors for breast cancer development, approximately 60% of patients with breast cancer have no known risk factor, although this situation will probably change with further research, especially in genetics. For patients with risk factors based on personal or family history, different models are available for assessing and quantifying risk. Assignment of risk levels permits tailored screening and risk reduction strategies. Potential benefits of specialized programs for women with high breast cancer risk include more cost -effective interventions as a result of patient stratification on the basis of risk; generation of valuable data to advance science; and differentiation of breast programs from other breast cancer units, which can result in increased revenue that can be directed to further improvements in patient care. Guidelines for care of patients at high risk for breast cancer are available from various groups. However, running a high-risk breast program involves much more than applying a guideline. Each high-risk program needs to be designed by its institution with consideration of local resources and country legislation, especially related to genetic issues. Development of a successful high-risk program includes identifying strengths, weaknesses, opportunities, and threats; developing a promotion plan; choosing a risk assessment tool; defining “high risk”; and planning screening and risk reduction strategies for the specific population served by the program. The information in this article may be useful for other institutions considering creation of programs for patients with high breast cancer risk. PMID:23833688

Healthcare settings screen broadly for HIV. Public health settings use social network and partner testing ("Transmission Network Targeting (TNT)") to select high-risk individuals based on their contacts. HIV screening and TNT systems are not integrated, and healthcare settings have not implemented TNT. The study aimed to evaluate pilot implementation of multi-component, multi-venue TNT in conjunction with HIV screening by a healthcare setting. Our urban, academic health center implemented a TNT program in collaboration with the local health department for five months during 2011. High-risk or HIV positive patients of the infectious diseases clinic and emergency department HIV screening program were recruited to access social and partner networks via compensated peer-referral, testing of companions present with them, and partner notification services. Contacts became the next-generation index cases in a snowball recruitment strategy. The pilot TNT program yielded 485 HIV tests for 482 individuals through eight generations of recruitment with five (1.0%; 95% CI = 0.4%, 2.3%) new diagnoses. Of these, 246 (51.0%; 95% CI = 46.6%, 55.5%) reported that they had not been tested for HIV within the last 12 months and 383 (79.5%; 95% CI = 75.7%, 82.9%) had not been tested by the existing ED screening program within the last five years. TNT complements population screening by more directly targeting high-risk individuals and by expanding the population receiving testing. Information from existing healthcare services could be used to seed TNT programs, or TNT could be implemented within healthcare settings. Research evaluating multi-component, multi-venue HIV detection is necessary to maximize complementary approaches while minimizing redundancy.

To evaluate the effectiveness of a community-based liver cancer prevention program on hepatitis B virus (HBV) screening among low-income, underserved Vietnamese Americans at high risk. We conducted a cluster randomized trial involving 36 Vietnamese community-based organizations and 2337 participants in Pennsylvania, New Jersey, and New York City between 2009 and 2014. We randomly assigned 18 community-based organizations to a community-based multilevel HBV screening intervention (n = 1131). We randomly assigned the remaining 18 community-based organizations to a general cancer education program (n = 1206), which included information about HBV-related liver cancer prevention. We assessed HBV screening rates at 6-month follow-up. Intervention participants were significantly more likely to have undergone HBV screening (88.1%) than were control group participants (4.6%). In a Cochran-Mantel-Haenszel analysis, the intervention effect on screening outcomes remained statistically significant after adjustment for demographic and health care access variables, including income, having health insurance, having a regular health provider, and English proficiency. A community-based, culturally appropriate, multilevel HBV screening intervention effectively increases screening rates in a high-risk, hard-to-reach Vietnamese American population.

Esophageal, gastric, and colorectal cancers are deadly diseases that continue to plague our world today. The value of screening endoscopy in evaluating these types of cancers is a critical area of discussion due to a potential reduction in morbidity and mortality. This article describes how to identify a good screening test and explains what are important criteria in the field of screening endoscopy. Furthermore, the current status and progress of screening endoscopy for esophageal, gastric, and colorectal cancer will be evaluated and discussed. Mass screening programs have not been implemented for esophageal and gastric carcinomas in those with average or low risk populations. However, studies of high-risk populations have found value and a cost-benefit in conducting screening endoscopy. Colorectal cancer, on the other hand, has had mass screening programs in place for many years due to the clear evidence of improved outcomes. As the role of endoscopy as a screening tool has continued to develop, newer technology and techniques have emerged to improve its utility. Many new image enhancement techniques and computer processing programs have shown promise and may have a significant role in the future of endoscopic screening. These developments are paving the way for improving the diagnostic and therapeutic capability of endoscopy in the field of gastroenterology. PMID:26361416

Few population-based data are available indicating the breast cancer risk following detection of atypia within a breast screening program. Prospectively collected data from the South Australian screening program were linked with the state cancer registry. Absolute and relative breast cancer risk estimates were calculated for ADH and ALH separately, and by age at diagnosis and time since diagnosis. Post-hoc analysis was undertaken of the effect of family history on breast cancer risk. Women with ADH and ALH had an increase in relative risk for malignancy (ADH HR 2.81 [95% CI 1.72, 4.59] and (ALH HR 4.14 [95% CI 1.97, 8.69], respectively. Differences in risk profile according to time since diagnosis and age at diagnosis were not statistically significant. Estimates of the relative risk of breast cancer are necessary to inform decisions regarding clinical management and/or treatment of women with ADH and ALH. Copyright © 2015 Elsevier Ltd.

There is considerable evidence regarding the efficacy and effectiveness of BRCA genetic testing programs, but whether they represent good use of financial resources is not clear. Therefore, we aimed to identify the main health-care programs for BRCA testing and to evaluate their cost-effectiveness. We performed a systematic review of full economic evaluations of health-care programs involving BRCA testing. Nine economic evaluations were included, and four main categories of BRCA testing programs were identified: (i) population-based genetic screening of individuals without cancer, either comprehensive or targeted based on ancestry; (ii) family history (FH)-based genetic screening, i.e., testing individuals without cancer but with FH suggestive of BRCA mutation; (iii) familial mutation (FM)-based genetic screening, i.e., testing individuals without cancer but with known familial BRCA mutation; and (iv) cancer-based genetic screening, i.e., testing individuals with BRCA-related cancers. Currently BRCA1/2 population-based screening represents good value for the money among Ashkenazi Jews only. FH-based screening is potentially very cost-effective, although further studies that include costs of identifying high-risk women are needed. There is no evidence of cost-effectiveness for BRCA screening of all newly diagnosed cases of breast/ovarian cancers followed by cascade testing of relatives, but programs that include tools for identifying affected women at higher risk for inherited forms are promising. Cost-effectiveness is highly sensitive to the cost of BRCA1/2 testing.Genet Med 18 12, 1171-1180.

To evaluate the cost-effectiveness of various melanoma screening strategies proposed in the United States. We developed a computer simulation Markov model to evaluate alternative melanoma screening strategies. Hypothetical cohort of the general population and siblings of patients with melanoma. Intervention We considered the following 4 strategies: background screening only, and screening 1 time, every 2 years, and annually, all beginning at age 50 years. Prevalence, incidence, and mortality data were taken from the Surveillance, Epidemiology, and End Results Program. Sibling risk, recurrence rates, and treatment costs were taken from the literature. Outcomes included life expectancy, quality-adjusted life expectancy, and lifetime costs. Cost-effectiveness ratios were in dollars per quality-adjusted life year (US dollars/QALY) gained. In the general population, screening 1 time, every 2 years, and annually saved 1.6, 4.4, and 5.2 QALYs per 1000 persons screened, with incremental cost-effectiveness ratios of US dollars 10,100/QALY, US dollars 80,700/QALY, and US dollars 586,800/QALY, respectively. In siblings of patients with melanoma (relative risk, 2.24 compared with the general population), 1-time, every-2-years, and annual screenings saved 3.6, 9.8, and 11.4 QALYs per 1000 persons screened, with incremental cost-effectiveness ratios of US dollars 4000/QALY, US dollars 35,500/QALY, and US dollars 257,800/QALY, respectively. In higher risk siblings of patients with melanoma (relative risk, 5.56), screening was more cost-effective. Results were most sensitive to screening cost, melanoma progression rate, and specificity of visual screening. One-time melanoma screening of the general population older than 50 years is very cost-effective compared with other cancer screening programs in the United States. Screening every 2 years in siblings of patients with melanoma is also cost-effective.

Colorectal cancer (CRC) is a leading cause of cancer death in the United States. Early detection through recommended screening has been shown to have favorable treatment outcomes, yet screening rates among the medically underserved and uninsured are low, particularly for rural and minority populations. This study evaluated the effectiveness of a patient navigation program that addresses individual and systemic barriers to CRC screening for patients at rural, federally qualified community health centers. This quasi-experimental evaluation compared low-income patients at average risk for CRC (n = 809) from 4 intervention clinics and 9 comparison clinics. We abstracted medical chart data on patient demographics, CRC history and risk factors, and CRC screening referrals and examinations. Outcomes of interest were colonoscopy referral and examination during the study period and being compliant with recommended screening guidelines at the end of the study period. We conducted multilevel logistic analyses to evaluate the program's effectiveness. Patients at intervention clinics were significantly more likely than patients at comparison clinics to undergo colonoscopy screening (35% versus 7%, odds ratio = 7.9, P < .01) and be guideline-compliant on at least one CRC screening test (43% versus 11%, odds ratio = 5.9, P < .001). Patient navigation, delivered through the Community Cancer Screening Program, can be an effective approach to ensure that lifesaving, preventive health screenings are provided to low-income adults in a rural setting.

Objectives. We sought to determine cardiovascular risk factor prevalence rates among adults in Abu Dhabi, United Arab Emirates. Methods. We used self-reported indicators, anthropometric measures, and blood tests to screen 50 138 adults aged 18 years or older taking part in a population-wide cardiovascular screening program. Results. Participants’ mean age was 36.82 years (SD = 14.3); 43% were men. Risk factor prevalence rates were as follows: obesity, 35%; overweight, 32%; central obesity, 55%; diabetes, 18%; prediabetes, 27%; dyslipidemia, 44%; and hypertension, 23.1%. In addition, 26% of men were smokers, compared with 0.8% of women. Age-standardized diabetes and prediabetes rates were 25% and 30%, respectively, and age-standardized rates of obesity and overweight were 41% and 34%. Conclusions. This population-wide cardiovascular screening program demonstrated a high cardiovascular burden for our small sample in Abu Dhabi. The data form a baseline against which interventions can be implemented and progress monitored as part of the population-wide Abu Dhabi Cardiovascular Disease Program. PMID:21940918

Universal screening for Lynch syndrome (LS) among all cases of colorectal cancer (CRC) could increase the diagnosis of LS and reduce morbidity and mortality of LS-associated cancers. Given universal screening includes all patients, irrespective of high risk factors such early age at onset or family history of CRC, it is important to understand perspectives of all patients and not just those at high risk. As part of a study to assess the feasibility and implementation of universal screening, 189 patients newly diagnosed with CRC were surveyed about their interest in screening for LS and communication of results with at-risk family members. Overall, participants responded positively regarding screening for LS, with most wanting to know their genetic risks in general (86%) and risk of hereditary CRC (93%). Prior to receiving screening results, most participants stated they intended to share their screening results with parents (89%), siblings (96%), and children (96%). Of the 28 participants who received a positive LS screening result, 26 (93%) reported sharing their result with at least one first-degree family member. Interest in screening for LS and communication of screening results with family members was not associated with high risk factors. This study indicates that patients are interested in being screened for LS and that sharing information on the risk of LS with at-risk family members is not a significant barrier. These findings provide novel insight into patient perspectives about screening for LS and can guide successful implementation of universal screening programs. PMID:28176204

The fecal immunochemical test (FIT) has been widely used in preliminary screening for colorectal cancer (CRC). The high-risk factor questionnaire (HRFQ) and quantitative risk-assessment method (QRAM) are recommended for estimating the risk of CRC qualitatively and quantitatively in China. We aimed to prospectively compare the diagnostic values of CRC preliminary screening methods to identify which method is preferable as a screening strategy. Individuals aged 40-74 years old were enrolled in a mass CRC screening program from January 1, 2007 to December 31, 2014, in Jiashan County, Zhejiang Province, China. FIT of two stool specimens at 1-week intervals was performed by laboratory personnel and face-to-face interviews were conducted by trained investigators. Screening data in the program were linked to a CRC surveillance and registry system, and CRC cases reported in the system were regarded as true patients. A total of 96,043 subjects were included. The sensitivity and specificity of FIT for detecting CRC cases were 75.49% (95% CI 69.84-80.39) and 90.36% (95% CI 90.17-90.54), respectively. QRAM was more sensitive (p < 0.001) and less specific (p < 0.001) than HRFQ. The sensitivity and specificity of FIT along with HRFQ were 86.56% (95% CI 81.81-90.22) and 81.37% (95% CI 81.12-81.62), and those of FIT along with QRAM were 88.93% (95% CI 84.47-92.23) and 73.95% (95% CI 73.67-74.23). Our findings suggest that CRC preliminary screening with FIT and QRAM in parallel has high sensitivity and satisfactory specificity, and is a useful strategy in mass screening programs.

Breast cancer (BC) continues to be a major cause of morbidity and mortality among women throughout the world and in Iran. Lack of awareness and early detection program in developing country is a main reason for escalating the mortality. The present research was conducted to assess the Iranian women's level of knowledge about breast cancer risk factors, early warning signs, and therapeutic and screening approaches, and their correlated determinants. In a cross-sectional study, 2250 women before participating at a community based screening and public educational program in an institute of cancer research in Isfahan, Iran, in 2012 were investigated using a self-administered questionnaire about risk factors, early warning signs, and therapeutic and screening approaches of BC. Latent class regression as a comprehensive statistical method was used for evaluating the level of knowledge and its correlated determinants. Only 33.2%, 31.9%, 26.7%, and 35.8% of study participants had high awareness levels about screening approaches, risk factors, early warning signs and therapeutic modalities of breast cancer, respectively, and majority had poor to moderate knowledge levels. Most effective predictors of high level of awareness were higher educational qualifications, attending in screening and public educational programs, personal problem, and family history of BC, respectively. Results of current study indicated that the levels of awareness among study population about key elements of BC are low. These findings reenforce the continuing need for more BC education through conducting public and professional programs that are intended to raise awareness among younger, single women and those with low educational attainments and without family history.

Skin cancer screening programs may attract the "worried well," while those at greatest risk for skin cancer are less likely to attend. Our purpose was to compare the results of skin cancer screening examinations between persons participating in the 1992 American Academy of Dermatology-sponsored free skin cancer screening and surfers participating in a free beachfront skin cancer screening held in conjunction with a regional surfing competition. The hypothesis was that screening an at-risk population (ie, surfers) would be more productive in terms of incidence of clinically diagnosed malignant skin lesions. Surfers were significantly younger and predominantly male. The incidence of basal cell carcinoma was significantly greater in the surfing population than in the self-selected population with similar ages. This study indicates that directed skin cancer screening of an at-risk population was more productive in finding skin cancer than screening of a self-selected population. Future efforts to identify individuals with skin cancer should be broadened to include high-risk populations such as daytime outdoor athletes and high-risk occupational groups, since they may not be reached by current screening efforts.

To profile and compare the content and presentation of written communications related to informed decision-making about mammography. Materials from 16 screening programs organized at the national or regional level were analyzed according to five major information domains suggested by the international literature. A majority of countries provided information on the program (interval, cost and quality). There was considerable variability in comprehensiveness of elements in the domains, e.g., test characteristics (false positive/negative) and pros and cons of screening. The majority noted the likelihood of recall for further tests, few commented on the risks of additional tests or finding unimportant tumors. The audit also found variation in presentation (words and pictures). Presentation of comprehensive, but balanced information on screening benefits and risks is complex and daunting. Issues such as framing effects, coupled with debate about screening efficacy are challenging to the design of effective information tools. The objective of increasing screening prevalence at the population level must be balanced with objectively presenting complete and clear information. Additional research is needed on how information (and mode of presentation) impact screening decisions. Public health officials need to articulate their objectives and review written communication according to important decision-making domains.

2013-05-01

Incidence-based evaluations of cervical cancer screening programs have suggested age-specific impacts and there is uncertainty regarding the effectiveness of screening outside the ages of 30-60 years. We audited the screening histories of cervical cancer deaths and conducted a case-control evaluation of the effectiveness of organized screening in different ages with mortality as outcome. We included all 506 cervical cancer deaths in Finland in 2000-2009 due to cancers diagnosed in 1990 or later, and 3,036 controls matched by age at diagnosis to the cases. Squamous cell carcinoma constituted 59% of the cases, adenocarcinomas 29%, and the remaining 12% were other specified and unspecified cervical malignancies. Most deaths (54%) were due to cancers diagnosed more than 5 years after last screening invitation, 24% were diagnosed among nonattenders and only 14% of deaths occurred among women who had attended invitational screening. The risk reduction associated with attending a single program screen at an age below 40 was nonsignificant (OR 0.70; 95% CI 0.33-1.48), while clear risk reductions were observed after screening at the age of 40-54 (OR 0.33; CI 0.20-0.56) and 55-69 (OR 0.29; CI 0.16-0.54). This study also provides some indication of a long-lasting additional effect of screening at the age of 65. Possible avenues for improving the effectiveness of the Finnish screening program include efforts to increase attendance and an extension of the target ages to include 65-to 69-year-old women. The potential benefit of increasing the sensitivity of the screening test or shortening the screening interval is smaller. Copyright © 2012 UICC.

The balance sheet of benefits and harms of breast cancer population-based screening in Europe: outcome research, practice and future challenges.

Breast cancer screening programs are still object of harsh debate. In 2012, the Independent UK Panel reviewed the benefits and harms of mammography screening based on randomized trials and the EUROSCREEN Working Group reviewed European observational outcome studies. The conclusion was that screening programs should continue, while acknowledging that harms, such as the occurrence of false-positive results and overdiagnosis, can have a negative impact on a woman's life. Information on the balance sheet of the benefits and harms of breast cancer screening should help women and their physicians to make an informed choice. The future challenge for breast screening programs is to assess the feasibility, acceptability, effectiveness and impact of risk-based screening in order to maximize benefit-to-harm ratios.

Prostate-Specific Antigen (PSA)–Based Population Screening for Prostate Cancer: An Evidence-Based Analysis

Pron, G

2015-01-01

Background Prostate cancer (PC) is the most commonly diagnosed non-cutaneous cancer in men and their second or third leading cause of cancer death. Prostate-specific antigen (PSA) testing for PC has been in common practice for more than 20 years. Objectives A systematic review of the scientific literature was conducted to determine the effectiveness of PSA-based population screening programs for PC to inform policy decisions in a publicly funded health care system. Data Sources A systematic review of bibliographic databases was performed for systematic reviews or randomized controlled trials (RCT) of PSA-based population screening programs for PC. Review Methods A broad search strategy was employed to identify studies reporting on key outcomes of PC mortality and all-cause mortality. Results The search identified 5 systematic reviews and 6 RCTs. None of the systematic reviews found a statistically significant reduction in relative risk (RR) of PC mortality or overall mortality with PSA-based screening. PC mortality reductions were found to vary by country, by screening program, and by age of men at study entry. The European Randomized Study of Screening for Prostate Cancer found a statistically significant reduction in RR in PC mortality at 11-year follow-up (0.79; 95% CI, 0.67–0.92), although the absolute risk reduction was small (1.0/10,000 person-years). However, the primary treatment for PCs differed significantly between countries and between trial arms. The American Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) found a statistically non-significant increase in RR for PC mortality with 13-year follow-up (1.09; 95% CI, 0.87–1.36). The degree of opportunistic screening in the control arm of the PLCO trial, however, was high. None of the RCTs found a reduction in all-cause mortality and all found a statistically significant increase in the detection of mainly low-risk, organ-confined PCs in the screening arm. Conclusions There was no evidence of a PC mortality reduction in the American PLCO trial, which investigated a screening program in a setting where opportunistic screening was already common practice. Given that opportunistic PSA screening practices in Canada are similar, it is unlikely that the introduction of a formal PSA screening program would reduce PC mortality. PMID:26366236

None of the RCTs found a reduction in all-cause mortality and all found a statistically significant increase in the detection of mainly low-risk, organ-confined PCs in the screening arm. There was no evidence of a PC mortality reduction in the American PLCO trial, which investigated a screening program in a setting where opportunistic screening was already common practice. Given that opportunistic PSA screening practices in Canada are similar, it is unlikely that the introduction of a formal PSA screening program would reduce PC mortality.

Trypanosoma cruzi is a parasitic infection endemic in Central and Southern America, but is spreading into nonendemic countries with migration of infected individuals from endemic countries. The parasite is transmitted by transfusion or transplantation and donation screening is performed routinely in endemic countries to prevent transmission. In situations where migrants from endemic countries have settled in nonendemic countries and present as donors (blood or other cellular products), intervention is required to prevent transfusion or transplantation transmission. A screening program for T. cruzi was developed and has been used successfully for over 10 years that includes donor selection and donation screening. Donor selection criteria to identify specific risk of T. cruzi infection were developed together with laboratory screening of donations for T. cruzi antibodies and the subsequent confirmation of screen reactivity. Since the introduction of T. cruzi screening in England in 1998, a total of 38,585 donors and donations have been screened for T. cruzi antibodies, of which 223 were repeat reactive on screening and referred for confirmation: 206 confirmed negative, 14 inconclusive, and three positive. Since the move in 2005 from donor qualification to donation release testing, 15,536 donations were collected and screened, of which 15,499 (99.8%) were T. cruzi antibody negative and released to inventory. An effective program to minimize risk of the transmission of T. cruzi infection via donations has been developed and implemented. Not only does the program minimize risk of transmission, it also minimizes the cumulative, and needless, loss of donors and donations that would ensue if permanent donor deferral alone was adopted. © 2012 American Association of Blood Banks.

Benign breast disease increases the risk of breast cancer. This association has scarcely been evaluated in the context of breast cancer screening programs although it is a prevalent finding in mammography screening. We assessed the association of distinct categories of benign breast disease and subsequent risk of breast cancer, as well as the influence of a family history of breast cancer. A retrospective cohort study was conducted in 545,171 women aged 50-69 years biennially screened for breast cancer in Spain. The median of follow-up was 6.1 years. The age-adjusted rate ratio (RR) of breast cancer for women with benign breast disease, histologically classified into nonproliferative and proliferative disease with and without atypia, compared with women without benign breast disease was estimated by Poisson regression analysis. A stratified analysis by family history of breast cancer was performed in a subsample. All tests were two-sided. The age-adjusted RR of breast cancer after diagnosis of benign breast disease was 2.51 (95 % CI: 2.14-2.93) compared with women without benign breast disease. The risk was higher in women with proliferative disease with atypia (RR = 4.56, 95 % CI: 2.06-10.07) followed by those with proliferative disease without atypia (RR = 3.58; 95 % CI = 2.61-4.91). Women with nonproliferative disease and without a family history of breast cancer remained also at increased risk of cancer (OR = 2.23, 95 % CI: 1.86-2.68). An increased risk of breast cancer was observed among screening participants with proliferative or nonproliferative benign breast disease, regardless of a family history of breast cancer. This information may be useful to explore risk-based screening strategies.

To map prenatal screening and diagnostic testing pathways in Victorian pregnant women during 2003 to 2004; measure the impact of prenatal diagnostic testing uptake on the effectiveness of prenatal screening for Down syndrome; and assess factors influencing uptake of diagnostic testing following screening. State-wide data collections of prenatal screening and diagnostic tests were linked to all Victorian births and pregnancy terminations for birth defects. Overall, 52% of women had a prenatal test (65 692/126 305); screening (44.9%), diagnostic testing (3.9%), or both (3.2%). Uptake of diagnostic testing was 71.4% (2390/3349) after an increased risk screen result, and 2.5% (1381/54 286) after a low risk result. Variation in uptake of diagnostic testing reduced the effectiveness of the screening program by 11.2%: from 87.4% (sensitivity - 125/143) to 76.2% (prenatal diagnoses of Down syndrome - 109/143). In both the increased and low risk groups, uptake was influenced by absolute numerical risk, as well as by the change in numerical risk from a priori risk. This comprehensive follow-up demonstrates clearly that numerical risk is being used to aid in decision making about confirmatory diagnostic testing. Collectively, these fundamental individual decisions will impact on the overall effectiveness of screening programmes for Down syndrome.

To establish the feasibility and acceptability of home-based HPV self-sampling among women who did not attend screening appointments in rural El Salvador. In a cross-sectional study, data were collected from May 2015 to January 2016 among 60 women aged 30-59 years who were not pregnant, provided informed consent, had not been screened in 2 years, had no history of pre-cancer treatment, and did not attend a scheduled HPV screening. Participants completed questionnaires and received educational information before being given an opportunity to self-sample with the Hybrid Capture 2 High Risk HPV DNA Test. Self-sampling was accepted by 41 (68%) participants. Almost all women chose to self-sample because the process was easy (40/41, 98%), could be performed at home (40/41, 98%), and saved time (38/41, 93%), and because they felt less embarrassed (33/41, 80%). The most common reason for declining the test was not wanting to be screened (8/19, 42%). The prevalence of high-risk HPV types among women who accepted self-sampling was 17% (7/41). For most women, community-based self-sampling was an acceptable way to participate in a cervical cancer screening program. In low-resource countries, incorporating community-based self-sampling into screening programs might improve coverage of high-risk women. © 2017 International Federation of Gynecology and Obstetrics.

The U.S. Preventive Services Task Force (USPSTF) recently updated their national lung screening guidelines and recommended low-dose computed tomography (LDCT) for lung cancer (LC) screening through age 80. However, the risk of overdiagnosis among older populations is a concern. Using four comparative models from the Cancer Intervention and Surveillance Modeling Network, we evaluate the overdiagnosis of the screening program recommended by USPSTF in the U.S. 1950 birth cohort. We estimate the number of LC deaths averted by screening (D) per overdiagnosed case (O), yielding the ratio D/O, to quantify the trade-off between the harms and benefits of LDCT. We analyze 576 hypothetical screening strategies that vary by age, smoking, and screening frequency and evaluate efficient screening strategies that maximize the D/O ratio and other metrics including D and life-years gained (LYG) per overdiagnosed case. The estimated D/O ratio for the USPSTF screening program is 2.85 (model range: 1.5-4.5) in the 1950 birth cohort, implying LDCT can prevent ∼3 LC deaths per overdiagnosed case. This D/O ratio increases by 22% when the program stops screening at an earlier age 75 instead of 80. Efficiency frontier analysis shows that while the most efficient screening strategies that maximize the mortality reduction (D) irrespective of overdiagnosis screen through age 80, screening strategies that stop at age 75 versus 80 produce greater efficiency in increasing life-years gained per overdiagnosed case. Given the risk of overdiagnosis with LC screening, the stopping age of screening merits further consideration when balancing benefits and harms. © 2017 UICC.

To evaluate the feasibility, performance, and cost of a breast cancer screening program aimed at 40-49-year-old women and tailored to their risk profile with supplemental ultrasonography (US) and magnetic resonance (MR) imaging. The institutional review board approved this study, and informed written consent was obtained. A total of 3017 40-49-year-old women were invited to participate. The screening program was tailored to lifetime risk (Gail test) and mammographic density (according to Breast Imaging Reporting and Data Systems [BI-RADS] criteria) with supplemental US or MR imaging and bilateral two-view microdose mammography. The indicators suggested by European guidelines, US incremental cancer detection rate (CDR), and estimated costs were evaluated. A total of 1666 women (67.5% participation rate) were recruited. The average lifetime risk of breast cancer was 11.6%, and nine women had a high risk of breast cancer; 917 women (55.0%) had a high density score (BI-RADS density category 3 or 4). The average glandular dose for screening examinations was 1.49 mGy. Screening US was performed in 835 study participants (50.1%), mostly due to high breast density (800 of 1666 women [48.0%]). Screening MR imaging was performed in nine women (0.5%) at high risk for breast cancer. Breast cancer was diagnosed in 14 women (8.4 cases per 1000 women). Twelve diagnoses were made with microdose mammography, and two were made with supplemental US in dense breasts (2.4 cases per 1000 women). All patients were submitted for surgery, and 10 underwent breast-conserving surgery. The sentinel lymph node was evaluated in 11 patients, resulting in negative findings in six. Pathologic analysis resulted in the diagnosis of four ductal carcinomas in situ and 10 invasive carcinomas (five at stage I). A tailored breast cancer screening program in 40-49-year-old women yielded a greater-than-expected number of cancers, most of which were low-stage disease.

Breast cancer is the most common type of cancer in women throughout the world. However, in comparison with Western women, it presents relatively early in women of Asian ethnicity. Early menarche, late menopause, use of OCP's, family history of benign or malignant breast disease, exposure to radiation and BMI in the under-weight range are well known risk factors for the development of breast cancer in premenopausal women. Early detection with the use of breast self-examination (BSE) and breast cancer screening programs can lead to a reduction in the mortality rates due to breast cancer. The aim of our study was to assess the risk factors for breast cancer among young women and to emphasize the importance of early screening among them. We conducted a cross-sectional study among women aged 18 to 25 using a self- administered questionnaire. Data was collected over a period of 6 months from June to December, 2014. A total of 300 young women selected randomly from Dow Medical College and various departments of Karachi University successfully completed the survey. Respondents were 18-25 years of age (mean age=21.5). Out of the 300 young females, 90 (30%) had at least one risk factor, 90 (30%) had two, 40 (13%) had three, 8 (2.7%) had four, 2 (0.7%) had five while one female was found to have six positive risk factors for breast cancer. Some 66 women (22%) experienced symptoms of breast cancer such as non-cyclical pain and lumps. While 222 women (74%) had never performed breast self-examination, 22 (7.3%) had had a breast examination done by a health professional while 32 (10.7%) had participated in breast screening programs. A total of 223 (74.3%) women considered breast cancer screening important for young women. The percentage of young women with risk factors for breast cancer was found to be alarmingly high. Therefore, screening for breast cancer should start at an early age especially in high risk groups. Awareness about breast self-examination should be emphasized. Moreover, screening programs should be started to ensure early detection and reduction of mortality rates caused by breast cancer also in young Pakistani females.

Effectively promoting women's health during and around the time of pregnancy requires early, nonstigmatizing identification and assessment of behavioral health risks (such as depression, substance use, smoking, and interpersonal violence) combined with timely linkage to community support and specialized interventions. This article describes an integrated approach to behavioral health risk screening woven into a point of first contact with the health care delivery system: centralized intake for maternal and child health home visiting programs. Behavioral Health Integrated Centralized Intake is a social work-informed, community-designed approach to screening, brief intervention, and service linkage targeting communities at high risk for fetal and infant mortality. Women enrolled in this study were receptive to holistic risk screening as well as guided referral for both home visiting support and specialized mental health interventions. Results from this multi-community study form the foundation for strengths-based, social work-informed enhancements to community health promotion programs. © 2017 National Association of Social Workers.

LIFECHECK, a voluntary, in-plant cardiovascular risk identification and modification program, was developed to complement Coors Wellness Center-based programs. LIFECHECK was offered to the 1,320 employees located at the Coors Engineering Center and Can Manufacturing Complex at the Coors Brewing Company. The initial 30-minute screening included height, weight, blood pressure, cholesterol, smoking history, weekly Kcal expenditure, self-rating of health, and health effects of stress. Participants concluded the screening session with a wellness counselor who reviewed results and referred them to the appropriate intervention activities. The eight-week intervention was provided at the worksite and was available to all shifts. The intervention included an activity competition and activity classes; nutrition, hypertension, smoking, and lipid classes; a smoke-out day; one-on-one counseling; exercise equipment at four worksites; posters; traymats; table tents; and electronic messages. A total of 692 employees, 52% of those eligible, participated in the initial screening. Of these, 91% had one or more risk factors, and 33% had three to five cardiovascular disease risk factors. A total of 499 employees, 72% of those eligible, completed the follow-up screening. Thirty-two percent of the employees who participated in LIFECHECK had not used the Wellness Center in the eight years it had been open. There were significant changes in employees who completed the eight-week program for systolic blood pressure, total cholesterol, weight, physical activity, and risk of ischemic heart disease within eight years as measured by the Framingham score (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

A protocol for bladder cancer screening and medical surveillance among high-risk groups: The Drake Health Registry experience

Marsh, G.M.; Callahan, C.; Pavlock, D.

In 1986, the Drake Health Registry Study initiated bladder cancer screening for 366 persons at high risk because of occupational exposure to beta-naphthylamine. The Drake Health Registry Study screening protocol consists of urinalysis, Papanicolaou cytology, and quantitative fluorescence image analysis. A positive screening test qualifies participants for a full diagnostic evaluation. The screening protocol has been modified during the first 3 years of the program's existence to address unexpected patterns of test results and to incorporate advances in screening technology. The current protocol, which has a two-tiered screening schedule, has been utilized successfully for 15 months. Of the 26 positivemore » results to date most have been based on abnormal Papanicolaou cytology and/or quantitative fluorescence image analysis. Bladder abnormalities were cited among most of the 18 study members who underwent diagnostic evaluation, including chronic cystitis, inflammation, hyperplasia, and dysplasia. We conclude that the screening program is detecting very early changes in a relatively young cohort and that these persons must be monitored over a number of years to ensure adequate medical surveillance.« less

The National Oral Health Screening Program (NOHSP) is a general population-based program in Korea. The objective of this study was to assess the association between participation in the NOHSP and dental visit for periapical abscess (PA) and advanced periodontal disease (APD) among Korean adults. Data were obtained for subjects from the National Health Insurance database. The authors conducted a retrospective cohort study of 9358 randomly selected subjects who were between 40 and 64 years old in 2002. The outcomes of dental visit for PA or APD from the years 2003 to 2007 were compared between the screening and nonscreening groups. The nonscreening group had 19% higher risk of PA and 15% higher risk of APD. This study suggests that the NOHSP may decrease the risk of dental visit because of PA and APD by preventing the progress of lesion to the advanced stage among Korean adults.

Outdoor recreation can lead to substantial sun exposure. Employees of outdoor recreation establishments with extended time outdoors have amplified cumulative exposure to ultraviolet (UV) radiation and an increased risk of skin cancer. The "Sun Safe on the Slopes" program was created by Huntsman Cancer Institute at the University of Utah and the Utah Cancer Action Network to address increased UV exposure and skin cancer risk with free skin cancer screenings, outreach, and prevention education to local ski resorts. Herein, we describe the processes and barriers to implementation of a ski resort skin screening and education program and our 5-year report of the experience and screening data. Nine free skin cancer screenings were held at Utah ski resorts between 2011 and 2016, resulting in the presumptive diagnosis of 38 skin cancers (9.6%) in 394 participants. Behavioral data collected from participants indicates suboptimal sun safety practices, including underuse of sunscreen and protective clothing. Ski resort employees who experience sun exposure during peak hours at high altitudes and UV reflection from the snow are at an increased risk of skin cancer. These data indicate a need for emphasis on sun safety education and screening and can serve as a model for future endeavors.

Individual risk prediction and stratification based on polygenic profiling may be useful in disease prevention. Risk-stratified population screening based on multiple factors including a polygenic risk profile has the potential to be more efficient than age-stratified screening. In this article, we summarize the implications of personalized screening for breast and prostate cancers. We report the opinions of multidisciplinary international experts who have explored the scientific, ethical, and logistical aspects of stratified screening. We have identified (i) the need to recognize the benefits and harms of personalized screening as compared with existing screening methods, (ii) that the use of genetic data highlights complex ethical issues including discrimination against high-risk individuals by insurers and employers and patient autonomy in relation to genetic testing of minors, (iii) the need for transparency and clear communication about risk scores, about harms and benefits, and about reasons for inclusion and exclusion from the risk-based screening process, and (iv) the need to develop new professional competences and to assess cost-effectiveness and acceptability of stratified screening programs before implementation. We conclude that health professionals and stakeholders need to consider the implications of incorporating genetic information in intervention strategies for health-care planning in the future.

The integration of community health workers (CHWs) into primary and secondary prevention functions in health programs and services delivery in Mexico and South Africa has been demonstrated to be effective. Task-sharing related to adherence and treatment, from nurses to CHWs, has also been effectively demonstrated in these areas. HIV/AIDS and TB programs in South Africa have seen similar successes in task-sharing with CHWs in the areas of screening for risk and adherence to treatment. In the area of non-communicable diseases (NCDs), there is a policy commitment to integrating CHWs into primary health care programs at public health facilities in both Mexico and South Africa in the areas of reproductive health and infant health. Yet current programs utilizing CHWs are not integrated into existing primary health care services in a comprehensive manner for primary and secondary prevention of NCDs. In a recently completed study, CHWs were trained to perform the basic diagnostic function of primary screening to assess the risk of suffering a CVD-related event in the community using a non-laboratory risk assessment tool and referring persons at moderate to high risk to local government clinics, for further assessment and management by a nurse or physician. In this paper we compare the experience with this CVD screening study to successful programs in vaccination, reproductive health, HIV/AIDS, and TB specifically to identify the barriers we identified as limitations to replicating these programs in the area of CVD diagnosis and management. We review barriers impacting the effective translation of policy into practice, including scale up issues; training and certification issues; integrating CHW to existing primary care teams and health system; funding and resource gaps. Finally, we suggest policy recommendations to replicate the demonstrated success of programs utilizing task-sharing with CHWs in infectious diseases and reproductive health, to integrated programs in NCD.

Assess patient adherence to radiologist recommendations in a clinical CT lung cancer screening program. Patients undergoing CT lung cancer screening between January 12, 2012, and June 12, 2013, were included in this institutional review board-approved retrospective review. Patients referred from outside our institution were excluded. All patients met National Comprehensive Cancer Network Guidelines Lung Cancer Screening high-risk criteria. Full-time program navigators used a CT lung screening program management system to schedule patient appointments, generate patient result notification letters detailing the radiologist follow-up recommendation, and track patient and referring physician notification of missed appointments at 30, 60, and 90 days. To be considered adherent, patients could be no more than 90 days past due for their next recommended examination as of September 12, 2014. Patients who died, were diagnosed with cancer, or otherwise became ineligible for screening were considered adherent. Adherence rates were assessed across multiple variables. During the study interval, 1,162 high-risk patients were screened, and 261 of 1,162 (22.5%) outside referrals were excluded. Of the remaining 901 patients, 503 (55.8%) were male, 414 (45.9%) were active smokers, 377 (41.8%) were aged 65 to 73, and >95% were white. Of the 901 patients, 772 (85.7%) were adherent. Most common reasons for nonadherence were patient refusal of follow-up exam (66.7%), inability to successfully contact the patient (20.9%), and inability to obtain the follow-up order from the referring provider (7.8%); 23 of 901 (2.6%) were discharged for other reasons. High rates of adherence to radiologist recommendations are achievable for in-network patients enrolled in a clinical CT lung screening program. Copyright © 2017 American College of Radiology.

In the Ashkenazi Jewish (AJ) population of Israel, 11% of breast cancer and 40% of ovarian cancer are due to three inherited founder mutations in the cancer predisposition genes BRCA1 and BRCA2. For carriers of these mutations, risk-reducing salpingo-oophorectomy significantly reduces morbidity and mortality. Population screening for these mutations among AJ women may be justifiable if accurate estimates of cancer risk for mutation carriers can be obtained. We therefore undertook to determine risks of breast and ovarian cancer for BRCA1 and BRCA2 mutation carriers ascertained irrespective of personal or family history of cancer. Families harboring mutations in BRCA1 or BRCA2 were ascertained by identifying mutation carriers among healthy AJ males recruited from health screening centers and outpatient clinics. Female relatives of the carriers were then enrolled and genotyped. Among the female relatives with BRCA1 or BRCA2 mutations, cumulative risk of developing either breast or ovarian cancer by age 60 and 80, respectively, were 0.60 (± 0.07) and 0.83 (± 0.07) for BRCA1 carriers and 0.33 (± 0.09) and 0.76 (± 0.13) for BRCA2 carriers. Risks were higher in recent vs. earlier birth cohorts (P = 0.006). High cancer risks in BRCA1 or BRCA2 mutation carriers identified through healthy males provide an evidence base for initiating a general screening program in the AJ population. General screening would identify many carriers who are not evaluated by genetic testing based on family history criteria. Such a program could serve as a model to investigate implementation and outcomes of population screening for genetic predisposition to cancer in other populations. PMID:25192939

Since 1998, after we started the support group for neonatal hearing screening, many other hearing screening programs were held in Brazil. In Alagoas, the first program started in 2003, but none of its results were published. Hearing is paramount for human communication; therefore, childhood hearing loss can impair speech acquisition, emotional, educational and social development. to present the results achieved in a neonatal hearing screening program in Maceió. a retrospective analytical study was carried out in order to study the results from tests carried out from September 2003 to December 2006 in a private hospital of Maceió. from a total of 2002 newborns, 1,626 fitted the inclusion criteria, 835 (51.4%) males. The hearing screening was considered appropriate in 1416 cases (87.1%), and the most frequently found age was between 16 and 30 days. Finally, 163 (10.0%) children presented risk indicators for hearing loss, and hyperbilirubinemia was the most common indicator. statistical results obtained from this hearing screening program show the importance of holding such programs. This study is important because it contributes to further regional or multinational studies.

Background Persons with a family history (FH) of colorectal cancer (CRC) or adenomas that are not due to known hereditary syndromes have increased risk for CRC. Understanding these risks, screening recommendations and screening behaviors can inform strategies to reduce CRC burden in these families. Methods A comprehensive review of literature published within the past 10 years was conducted to assess what is known about cancer risk, screening guidelines, adherence and barriers to screening and effective interventions in persons with FH of CRC, and to identify FH tools used to identify these individuals and inform care. Results Existing data show that having one affected first-degree relative (FDR) increases CRC risk by 2-fold, and risk increases with multiple affected FDRs and younger age at diagnosis. There was variability in screening recommendations across consensus guidelines. Screening adherence was <50% and lower in persons under age 50. Having a provider’s recommendation, multiple affected relatives and family encouragement facilitated screening; insufficient collection of FH, low knowledge of guidelines, and poor family communication were important barriers. Effective interventions incorporated strategies for overcoming barriers but these have not been tested broadly in clinical settings. Conclusions Four strategies for reducing CRC in persons with familial risk are suggested: 1) improve how we collect and utilize cancer FH, 2) establish consensus for screening guidelines by FH, 3) enhance provider-patient knowledge of guidelines and communication about CRC risk, 4) encourage survivors to promote screening within their families, and partner with existing screening programs to expand reach to high-risk groups.

The National Cholesterol Education Program (NCEP) has endorsed physician case finding as the primary method to detect individuals with elevated cholesterol levels. Despite this recommendation, promotional and for-profit public screening programs have flourished. We surveyed participants of a mall-based cholesterol screening program 1 year after their screening. Sixty-four percent of those screened had not previously known their cholesterol levels. Those who were newly screened were less likely to benefit from this testing than the general public, since they were older (mean age, 55.3 years), more likely to be female (67.4%), and nonsmokers (88%). Screenees had excellent recall of their cholesterol level (mean absolute reporting error, 0.24 mmol/L [9 mg/dL]) and a good understanding of cholesterol as a coronary heart disease risk. Those with elevated cholesterol levels reported high distress from screening but no reduction in overall psychosocial well-being and an actual decrease in absenteeism. Only 53.7% of all who were advised to seek follow-up because of an elevated screening value had done so within the year following the screening program. However, of those with values greater than 6.2 mmol/L (240 mg/dL), 68% had sought follow-up. Many of those who participate in public screening programs have been previously tested, fall into low-benefit groups, or fail to comply with recommended follow-up. We therefore conclude that cholesterol screening programs of the type now commonly offered are unlikely to contribute greatly to the national efforts to further reduce coronary heart disease.

Parent-child relational problems (PCRP) have been increasingly recognized as a risk factor in the development and/or progression of childhood mental illnesses. Despite many young individuals being at risk, health care providers do not specifically screen for PCRP in children diagnosed with mental illnesses. The objective of the current project was to implement a PCRP screening program in a metropolitan children's hospital and refer those with PCRP for treatment. Adolescents ages 10 to 17 presenting for admission in an inpatient pediatric psychiatric unit were screened with the PCRP semi-structured questionnaire and diagnostic criteria developed by the American Psychiatric Association's Relational Processes Workgroup. Eleven (73%) of 15 patients screened were found to have PCRP. Patients may be screened with a PCRP screening tool during biopsychosocial assessment without undue time burden on the provider. It is recommended that PCRP be added to electronic health records so providers can select PCRP in problem lists as well as formulate PCRP-sensitive care plans.

The Society of Behavioral Medicine (SBM) supports the United States Preventive Services Task Force (USPSTF) recommendation of low-dose computed tomography (LDCT) screening of the chest for eligible populations to reduce lung cancer mortality. Consistent with efforts to translate research findings into real-world settings, SBM encourages health-care providers and health-care systems to (1) integrate evidence-based tobacco treatment as an essential component of LDCT-based lung cancer screening, (2) examine the structural barriers that may impact screening uptake, and (3) incorporate shared decision-making as a clinical platform to facilitate consultations and engagement with individuals at high risk for lung cancer about the potential benefits and harms associated with participation in a lung cancer screening program. We advise policy makers and legislators to support screening in high-risk populations by continuing to (1) expand access to high quality LDCT-based screening among underserved high-risk populations, (2) enhance cost-effectiveness by integrating evidence-based tobacco treatments into screening in high-risk populations, and (3) increase funding for research that explores implementation science and increased public awareness and access of diverse populations to participate in clinical and translational research.

No consensus exists on screening to detect the estimated 2 million Americans unaware of their chronic hepatitis C infections. Advisory groups differ, recommending birth-cohort screening for baby boomers, screening only high-risk individuals, or no screening. We assessed one-time risk assessment and screening to identify previously undiagnosed 40-74 year-olds given newly available hepatitis C treatments. A Markov model evaluated alternative risk-factor guided and birth-cohort screening and treatment strategies. Risk factors included drug use history, blood transfusion before 1992, and multiple sexual partners. Analyses of the National Health and Nutrition Examination Survey provided sex-, race-, age-, and risk-factor-specific hepatitis C prevalence and mortality rates. Nine strategies combined screening (no screening, risk-factor guided screening, or birth-cohort screening) and treatment (standard therapy-peginterferon alfa and ribavirin, Interleukin-28B-guided (IL28B) triple-therapy-standard therapy plus a protease inhibitor, or universal triple therapy). Response-guided treatment depended on HCV genotype. Outcomes include discounted lifetime costs (2010 dollars) and quality adjusted life-years (QALYs). Compared to no screening, risk-factor guided and birth-cohort screening for 50 year-olds gained 0.7 to 3.5 quality adjusted life-days and cost $168 to $568 per person. Birth-cohort screening provided more benefit per dollar than risk-factor guided screening and cost $65,749 per QALY if followed by universal triple therapy compared to screening followed by IL28B-guided triple therapy. If only 10% of screen-detected, eligible patients initiate treatment at each opportunity, birth-cohort screening with universal triple therapy costs $241,100 per QALY. Assuming treatment with triple therapy, screening all individuals aged 40-64 years costs less than $100,000 per QALY. The cost-effectiveness of one-time birth-cohort hepatitis C screening for 40-64 year olds is comparable to other screening programs, provided that the healthcare system has sufficient capacity to deliver prompt treatment and appropriate follow-on care to many newly screen-detected individuals.

Early detection is considered to improve the prognosis of cutaneous melanoma. The value of population-based screening for melanoma, however, is still controversial. The aim of this study was to evaluate the predictive power of established risk factors in the setting of a population-based screening and to provide empirical evidence for potential risk stratifications. We reanalyzed data (including age, sex, risk factors, and screening results) of 354 635 participants in the Skin Cancer Research to provide Evidence for Effectiveness of Screening in Northern Germany project conducted in the German state of Schleswig-Holstein (2003-2004). In multivariable analysis, atypical nevi [odds ratio (OR): 17.4; 95% confidence interval (CI): 14.4-20.1], personal history of melanoma (OR: 5.3; 95% CI: 3.6-7.6), and multiple (≥40) common nevi (OR: 1.3; 95% CI: 1.1-1.6) were associated with an increased risk of melanoma detection. Family history and congenital nevi were not significantly associated with melanoma detection in the Skin Cancer Research to provide Evidence for Effectiveness of Screening in Northern Germany population. The effects of several risk-adapted screening strategies were evaluated. Hypothesizing a screening of individuals aged more than or equal to 35 years, irrespective of risk factors (age approach), the number needed to screen is 559 (95% CI: 514-612), whereas a screening of adults (aged ≥20) with at least one risk factor (risk approach) leads to an number needed to screen of 178 (95% CI: 163-196). Converted into one screen-detected melanoma, the number of missed melanomas is 0.15 (95% CI: 0.12-0.18) with the age approach and 0.22 (95% CI: 0.19-0.26) with the risk approach. The results indicate that focusing on individuals at high risk for melanoma may improve the cost-effectiveness and the benefit-to-harm balance of melanoma screening programs.

Background Interval cancers are primary breast cancers diagnosed in women after a negative screening test and before the next screening invitation. Our aim was to evaluate risk factors for interval cancer and their subtypes and to compare the risk factors identified with those associated with incident screen-detected cancers. Methods We analyzed data from 645,764 women participating in the Spanish breast cancer screening program from 2000–2006 and followed-up until 2009. A total of 5,309 screen-detected and 1,653 interval cancers were diagnosed. Among the latter, 1,012 could be classified on the basis of findings in screening and diagnostic mammograms, consisting of 489 true interval cancers (48.2%), 235 false-negatives (23.2%), 172 minimal-signs (17.2%) and 114 occult tumors (11.3%). Information on the screening protocol and women's characteristics were obtained from the screening program registry. Cause-specific Cox regression models were used to estimate the hazard ratios (HR) of risks factors for interval cancer and incident screen-detected cancer. A multinomial regression model, using screen-detected tumors as a reference group, was used to assess the effect of breast density and other factors on the occurrence of interval cancer subtypes. Results A previous false-positive was the main risk factor for interval cancer (HR = 2.71, 95%CI: 2.28–3.23); this risk was higher for false-negatives (HR = 8.79, 95%CI: 6.24–12.40) than for true interval cancer (HR = 2.26, 95%CI: 1.59–3.21). A family history of breast cancer was associated with true intervals (HR = 2.11, 95%CI: 1.60–2.78), previous benign biopsy with a false-negatives (HR = 1.83, 95%CI: 1.23–2.71). High breast density was mainly associated with occult tumors (RRR = 4.92, 95%CI: 2.58–9.38), followed by true intervals (RRR = 1.67, 95%CI: 1.18–2.36) and false-negatives (RRR = 1.58, 95%CI: 1.00–2.49). Conclusion The role of women's characteristics differs among interval cancer subtypes. This information could be useful to improve effectiveness of breast cancer screening programmes and to better classify subgroups of women with different risks of developing cancer. PMID:25333936

For an effective colorectal cancer (CRC) screening program, high participation rate is essential. However, non-participation in CRC screening program has increased in Finland. The study was based on a population-based nationwide cohort of persons invited for CRC screening in 2004-2011. Information on the first round of the CRC screening participation and related background factors was obtained from the Finnish Cancer Registry, and information about health behavior factors from the Health Behavior Survey (HBS) in 1978-1999. Non-participation in CRC screening was analyzed with Poisson regression as incidence rate ratios (IRR) with 95% confidence intervals (95% CI). Of all persons invited for CRC screening (79 871 men and 80 891 women) 35% of men and 21% of women refused. Of those invited for screening, 2456 men (3.1%) and 2507 women (3.1%) were also invited to the HBS. Persons, who declined HBS, were also more likely to refuse CRC screening (men IRR 1.40, 95% CI 1.26-1.56, women 1.75, 1.52-2.02) compared to HBS participants. Never married persons had about a 75% higher risk for refusing than married ones. The youngest age group (60 years) was more likely to refuse screening than the older age groups (62 or >64 years). Smoking was associated with non-participation in screening (current smokers, men: IRR 1.32, 95% CI 1.05-1.67, women: 2.10, 1.61-2.73). Participation in CRC screening was affected by gender, age, and marital status. Persons, who refused the HBS, were also more likely to refuse CRC screening. Smoking was a risk factor for non-participation in CRC screening.

Objectives. To determine whether persons at high risk of lung cancer would participate in lung cancer screening test if available in Australia and to elicit general attitudes towards cancer screening and factors that might affect participation in a screening program. Methods. We developed a 20-item written questionnaire, based on two published telephone interview scripts, addressing attitudes towards cancer screening, perceived risk of lung cancer, and willingness to be screened for lung cancer and to undertake surgery if lung cancer were detected. The questionnaire was given to 102 current and former smokers attending the respiratory clinic and pulmonary rehabilitation programmes. Results. We gained 90 eligible responses (M:F, 69:21). Mean [SD] age was 63 [11] and smoking history was 32 [21] pack years. 95% of subjects would participate in a lung cancer screening test, and 91% of these would consider surgery if lung cancer was detected. 44% of subjects considered that they were at risk of lung cancer. This was lower in ex-smokers than in current smokers. Conclusions. There is high willingness for lung cancer screening and surgical treatment. There is underrecognition of risk among ex-smokers. This misperception could be a barrier to a successful screening or case-finding programme in Australia. PMID:26316943

Screening and treating Chlamydia trachomatis genital infection to prevent pelvic inflammatory disease: interpretation of findings from randomized controlled trials.

Gottlieb, Sami L; Xu, Fujie; Brunham, Robert C

2013-02-01

We critically reviewed randomized controlled trials evaluating chlamydia screening to prevent pelvic inflammatory disease (PID) and explored factors affecting interpretation and translation of trial data into public health prevention. Taken together, data from these trials offer evidence that chlamydia screening and treatment is an important and useful intervention to reduce the risk of PID among young women. However, the magnitude of benefit to be expected from screening may have been overestimated based on the earliest trials. It is likely that chlamydia screening programs have contributed to declines in PID incidence through shortening prevalent infections, although the magnitude of their contribution remains unclear. Program factors such as screening coverage as well as natural history factors such as risk of PID after repeat chlamydia infection can be important in determining the impact of chlamydia screening on PID incidence in a population. Uptake of chlamydia screening is currently suboptimal, and expansion of screening among young, sexually active women remains a priority. To reduce transmission and repeat infections, implementation of efficient strategies to treat partners of infected women is also essential. Results of ongoing randomized evaluations of the effect of screening on community-wide chlamydia prevalence and PID will also be valuable.

Unfortunately, African American men have a higher incidence of and a higher mortality rate for prostate cancer than White men but are less likely to participate in prostate cancer screening. This correlational survey research identifies predictors for participation in a free prostate cancer screening in 179 men, 64% of whom are African American. Each man was invited to see his personal physician for a free prostate cancer screening following a prostate cancer educational program given at his worksite. Forty-seven percent of the African American men went to their personal physician following the educational program and received a digital rectal examination (DRE) and a prostate specific antigen (PSA) screening. In the original cohort of educational program attendees, only 16% of the African Americans had obtained a DRE in the previous 12 months. However, 44% subsequently did participate in free DRE screening. Similarly, only 6% of the African American men had received a PSA screening in the previous 12 months, yet 42% obtained a PSA screening after the educational program, a sevenfold increase. Implications for allocating limited resources for education and screening to the high-risk group of African American men are discussed. This study's model of a prostate cancer educational program at worksites followed by attendees visiting their personal physician for screening could be replicated throughout the United States to increase African American men's participation in prostate cancer screening.

Riata and Riata ST defibrillator leads (St. Jude Medical, Sylmar, California) were recalled in 2011 due to increased risk of insulation failure leading to externalized cables. Fluoroscopic screening can identify insulation failure, although the relation between mechanical failure and electrical failure is unclear. At the time of the recall, the University of Virginia developed a screening program, including fluoroscopic evaluation, education sessions, device interrogation, and remote monitoring for patients with this defibrillator lead. The aim of this study was to review the outcomes of the screening program, including costs, which were absorbed by our institution. Costs were calculated using Medicare reimbursement estimates. Forty-eight patients participated in the screening program. At initial screening, 31% were found to have evidence of insulation failure but electrical function was normal in all leads. The cost of this program was $35,358.72. The cost per diagnosis of mechanical lead failure was $2,357.25. During 2 years of follow-up, 1 patient experienced Riata lead electrical failure without fluoroscopic evidence of insulation failure. Patients were more likely to have a lead revision if there was evidence of insulation failure. Lead revisions occurred at the time of generator change in 88% of patients with insulation failure but in only 14% of patients with a fluoroscopically normal lead (p = 0.04). The cost of recall-related defibrillator lead revisions was $81,704.55. In conclusion, our Riata screening program added expense without clear benefit to patients. In fact, patients may have been put at more risk by undergoing defibrillator lead revisions based solely on the results of the fluoroscopic screening. Copyright © 2015 Elsevier Inc.

Persons with a family history (FH) of colorectal cancer (CRC) or adenomas that are not due to known hereditary syndromes have an increased risk for CRC. An understanding of these risks, screening recommendations, and screening behaviors can inform strategies for reducing the CRC burden in these families. A comprehensive review of the literature published within the past 10 years has been performed to assess what is known about cancer risk, screening guidelines, adherence and barriers to screening, and effective interventions in persons with an FH of CRC and to identify FH tools used to identify these individuals and inform care. Existing data show that having 1 affected first-degree relative (FDR) increases the CRC risk 2-fold, and the risk increases with multiple affected FDRs and a younger age at diagnosis. There is variability in screening recommendations across consensus guidelines. Screening adherence is <50% and is lower in persons under the age of 50 years. A provider's recommendation, multiple affected relatives, and family encouragement facilitate screening; insufficient collection of FH, low knowledge of guidelines, and poor family communication are important barriers. Effective interventions incorporate strategies for overcoming barriers, but these have not been broadly tested in clinical settings. Four strategies for reducing CRC in persons with familial risk are suggested: 1) improving the collection and utilization of the FH of cancer, 2) establishing a consensus for screening guidelines by FH, 3) enhancing provider-patient knowledge of guidelines and communication about CRC risk, and 4) encouraging survivors to promote screening within their families and partnering with existing screening programs to expand their reach to high-risk groups.

Breast cancer remains a worldwide public health problem. In Tunisia, it is considered to be the primary women's cancer and causes high morbidity and mortality. This study aimed to investigate female knowledge, attitudes and practice of breast cancer screening in the region of Monastir (Tunisia). We conducted a descriptive cross-sectional design exploring knowledge, attitudes and practices of women in the region of Monastir on breast cancer screening. The study was conducted in health centres of this region from 1 March 2009 to 30 June 2009. Data were collected via a structured questionnaire containing 15 items on demographic status, knowledge of risk factors and screening methods and attitudes towards the relevance and effectiveness of breast cancer screening. A scoring scheme was used to score women's responses. A total of 900 women agreed to take part in the study. Their mean age was 41.6±12.4 years and 64% did not exceed the primary level of education. According to the constructed scores, 92% of participants had poor knowledge of the specific risk factors for breast cancer and 63.2% had poor knowledge of the screening methods. Proper practice of breast cancer screening was observed in 14.3% of cases. Multiple logistic regression analysis showed that good knowledge of risk factors and screening methods, higher level of education and positive family history of breast cancer were independently correlated with breast cancer screening practice. This study revealed poor knowledge of breast cancer and the screening methods as well as low levels of practice of breast cancer screening among women in the region of Monastir. Results justify educational programs to raise women's adherence to breast cancer screening programs in Tunisia.

The purpose was to evaluate alternative cytological screening methods in population-based screening for cervical cancer up to cancer incidence and mortality outcome. Automation-assisted screening was compared to conventional cytological screening in a randomized design. The study was based on follow-up of 503,391 women invited in the Finnish cervical cancer screening program during 1999-2003. The endpoints were incident cervical cancer, severe intraepithelial neoplasia and deaths from cervical cancer. One third of the women had been randomly allocated to automation-assisted screening and two thirds to conventional cytology. Information on cervical cancer and severe neoplasia were obtained through 1999-2007 from a linkage between screening and cancer registry files. There were altogether 3.2 million woman-years at risk, and the average follow-up time was 6.3 years. There was no difference in the risk of cervical cancer between the automation-assisted and conventional screening methods; the relative risk (RR) of cervical cancer between the study and control arm was 1.00 (95% confidence interval [CI] = 0.76-1.29) among all invited and 1.08 (95% CI = 0.76-1.51) among women who were test negative at entry. Comparing women who were test negative with nonscreened, RR of cervical cancer incidence was 0.26, 95% CI = 0.19-0.36 and of mortality 0.24 (0.13-0.43). Both methods were valid for screening. Because cervical cancer is rare in our country, we cannot rule out small differences between methods. Evidence on alternative methods for cervical cancer screening is increasing and it is thus feasible to evaluate new methods in large-scale population-based screening programs up to cancer outcome.

HABITS for Life was a 3-year initiative to broadly deliver a statewide biometric and retinal screening program via a mobile unit throughout New Mexico at no charge to participants. The program goal-to identify health risk and improve population health status-was tested over a 3-year period. Value to participants and impact to the healthcare system were measured to quantify impact and value of investing in prevention at the community level. We used the Mobile Health Map Return-on-Investment Calculator, a mobile screening unit, biometric screening, retinography, and community coordination. Our systems included satellite, DSL, and 3G connectivity, a Tanita® (Arlington Heights, IL) automated body mass index-measuring scale, the Cholestec® (Alere™, Waltham, MA) system for biomarkers and glycosylated hemoglobin, a Canon (Melville, NY) CR-1 Mark II camera, and the Picture Archiving Communication System. In this report for the fiscal year 2011 time frame, 6,426 individuals received biometric screening, and 5,219 received retinal screening. A 15:1 return on investment was calculated; this excluded retinal screening for the under-65 year olds, estimated at $10 million in quality-adjusted life years saved. Statistically significant improvement in health status evidenced by sequential screening included a decrease in total cholesterol level (p=0.002) (n=308) and an increase in high-density lipoprotein level after the first and second screening (p=0.02 and p=0.01, respectively), but a decrease in mean random glucose level was not statistically significant (p=0.62). Retinal results indicate 28.4% (n=1,482) with a positive/abnormal finding, of which 1.79% (n=93) required immediate referral for sight-threatening retinopathy and 27% (n=1,389) required follow-up of from 3 months to 1 year. Screening programs are cost-effective and provide value in preventive health efforts. Broad use of screening programs should be considered in healthcare redesign efforts. Community-based screening is an effective strategy to identify health risk, improve access, provide motivation to change health habits, and improve physical status while returning significant value.

Objective: Ageing population and noticeable changes in lifestyle in developing countries like Iran caused an increase in cancer incidence. This requires organized cancer prevention and screening programs in population level, but most importantly community should be aware of these programs and willing to use them. This study explored existing evidence on public awareness and practice, as well as, adherence to cancer screening in Iranian population. Methods: Major English databases including Web of Science, PubMed, Scopus, and domestic Persian databases i.e., SID, Magiran, and Barakat search engines were searched. All publications with focus on Iranian public awareness about cancer prevention, screening, and early detection programs which were published until August 2015, were explored in this systematic review. For this purpose, we used sensitive Persian phrases/key terms and English keywords which were extracted from medical subject headings (MeSH). Taking PRISMA guidelines into considerations eligible documents, were evaluated and abstracted by two separate reviewers. Results: We found 72 articles relevant to this topic. Screening tests were known to, or being utilized by only a limited number of Iranians. Most Iranian women relied on physical examination particularly self-examination, instead of taking mammogram, as the most standard test to find breast tumors. Less than half of the average-risk adult populations were familiar with colorectal cancer risk factors and its screening tests, and only very limited number of studies reported taking at least one time colonoscopy or FOBT, at most 5.0% and 15.0%, respectively. Around half of women were familiar with cervical cancer and Pap-smear test with less than 45% having completed at least one lifetime test. The lack of health insurance coverage was a barrier to participate in screening tests. Furthermore some people would not select to be screened only because they do not know how or where they can receive these services. Conclusion: Low awareness and suboptimal use of screening tests in Iran calls for effective programs to enhance intention and compliance to screening, improving the patient-physician communication, identifying barriers for screening and providing tailored public awareness and screening programs.

Appel, Susan J; Cleiment, Rosemary J

2015-12-01

Approximately 5-10% of breast cancer cases appear in families at a higher rate and at an earlier onset than in the average population. Two known gene defects, BRCA1 and BRCA2, account for the majority of these hereditary related breast cancers. Additionally, BRCA1 and BRCA2 are related to the Hereditary Breast and Ovarian Cancer syndrome (HBOC), where risk for other related cancers are increased. Various health-care professional organizations provide guidelines that speak to the need for conducting risk assessments, but little research has been conducted focusing on the initial screening for this syndrome. This quality improvement project attempts to determine if Nurse Navigators can effectively perform the initial education and screening for HBOC syndrome within a mammography and women's breast imaging setting using a simplified patient history tool. E. M. Rodgers' Diffusion of Innovation model, a map of how new ideas and programs have become adopted and accepted, guided this project's development and implementation. Over the course of 8 weeks, 1,420 women seeking service at 3 mammography and imaging sites were given a new risk assessment tool for HBOC. Additionally, the use of Nurse Navigation to identify women who may be at risk for HBOC was implemented. Two populations seeking service at the study sites were evaluated: (1) women obtaining breast screening/imaging services and (2) women receiving breast biopsy results. Patients identified as "at-risk" were defined by evidence-based practice guidelines from the National Comprehensive Cancer Network and were referred for further genetic evaluation by a genetic professional. During this initial implementation of the HBOC risk assessment program, low participation of screening/imaging patients requesting HBOC education and evaluation occurred (129 screening patients or 9%). High rates of positive biopsy patients (5 patients or 34.7%) werefound to be at risk for HBOC compared to similar studies. Identifying HBOC risk at the time of breast biopsy results gave the opportunity to impact the timing and kind of surgical management of patients at risk for this syndrome.The Commission on Cancer (CoC), an arm of the American College of Surgeons, provides practice guideline standards and accreditation for cancer programs. Patients will become more familiar with being assessed for HBOC and other hereditary cancers during their annual health-care visits and more identification of patients at riskfor HBOC should occur as new CoC 2012 standards requiring hereditary cancer risk assessments for a cancer program's certification are enacted.

The increased risk of genetic cancer mutations for Ashkenazi Jews is well known. However, little is known about the cancer-related health behaviors of a subset of Ashkenazi Jews, Orthodox Jews, who are a very religious and insular group. This study partnered with Rabbinical leadership and community members in an Orthodox Jewish community to investigate barriers to cancer screening in this community. Orthodox Jewish women were recruited to participate in focus groups designed to elicit their perspectives on barriers to cancer screening. A total of five focus groups were conducted, consisting of 3-5 members per group, stratified by age and family history of cancer. Focus groups were audio recorded and transcribed. Transcripts were coded using conventional content analysis. The resulting themes identified as barriers to cancer screening were: preservation of hidden miracles, fate, cost, competing priorities, lack of culturally relevant programming, lack of information, and fear. These results provide a unique perspective on barriers to cancer screening in a high risk but understudied population. Findings from this study may serve to inform culturally appropriate cancer education programs to overcome barriers to screening in this and other similar communities.

Is screening and surveillance for early detection of gastric cancer needed in Korean Americans?

PubMed Central

Kim, Gwang Ha; Bang, Sung Jo; Ende, Alexander R.; Hwang, Joo Ha

2015-01-01

The incidence rate of gastric cancer in Korean Americans is over five times higher than that in non-Hispanic whites, and is similar to the incidence of colorectal cancer in the overall United States population. In Korea, the National Cancer Screening Program recommends endoscopy or upper gastrointestinal series for people aged 40 years and older every 2 years. However, the benefit of gastric cancer screening in Korean Americans has not been evaluated. Based on epidemiologic studies, Korean Americans appear to have more similar gastric cancer risk factors to Koreans as opposed to Americans of European descent, though the risk of gastric cancer appears to decrease for subsequent generations. Therefore, in accordance with recent recommendations regarding screening for gastric cancer in Korea, endoscopic screening for gastric cancer in Korean Americans should be considered, especially in those with known atrophic gastritis/intestinal metaplasia or a family history of gastric cancer. In the future, additional studies will needed to assess whether a screening program for gastric cancer in Korean Americans will result in a survival benefit. PMID:26552450

Several countries are implementing a transition to HPV testing for cervical screening in response to the introduction of HPV vaccination and evidence indicating that HPV screening is more effective than cytology. In Australia, a 2017 transition from 2-yearly conventional cytology in 18-20 to 69 years to 5-yearly primary HPV screening in 25 to 74 years will involve partial genotyping for HPV 16/18 with direct referral to colposcopy for this higher risk group. The objective of this study was to determine the optimal management of women positive for other high-risk HPV types (not 16/18) ('OHR HPV'). We used a dynamic model of HPV transmission, vaccination, natural history and cervical screening to determine the optimal management of women positive for OHR HPV. We assumed cytology triage testing was used to inform management in this group and that those with high-grade cytology would be referred to colposcopy and those with negative cytology would receive 12-month surveillance. For those with OHR HPV and low-grade cytology (considered to be a single low-grade category in Australia incorporating ASC-US and LSIL), we evaluated (1) the 20-year risk of invasive cervical cancer assuming this group are referred for 12-month follow-up vs. colposcopy, and compared this to the risk in women with low-grade cytology under the current program (i.e. an accepted benchmark risk for 12-month follow-up in Australia); (2) the population-level impact of the whole program, assuming this group are referred to 12-month surveillance vs. colposcopy; and (3) the cost-effectiveness of immediate colposcopy compared to 12-month follow-up. Evaluation was performed both for HPV-unvaccinated cohorts and cohorts offered vaccination (coverage ~72%). The estimated 20-year risk of cervical cancer is ≤1.0% at all ages if this group are referred to colposcopy vs. ≤1.2% if followed-up in 12 months, both of which are lower than the ≤2.6% benchmark risk in women with low-grade cytology in the current program (who are returned for 12-month follow-up). At the population level, immediate colposcopy referral provides an incremental 1-3% reduction in cervical cancer incidence and mortality compared with 12-month follow-up, but this is in the context of a predicted 24-36% reduction associated with the new HPV screening program compared to the current cytology-based program. Furthermore, immediate colposcopy substantially increases the predicted number of colposcopies, with >650 additional colposcopies required to avert each additional case of cervical cancer compared to 12-month follow-up. Compared to 12-month follow-up, immediate colposcopy has an incremental cost-effectiveness ratio (ICER) of A$104,600/LYS (95%CrI:A$100,100-109,100) in unvaccinated women and A$117,100/LYS (95%CrI:A$112,300-122,000) in cohorts offered vaccination [Indicative willingness-to-pay threshold: A$50,000/LYS]. In primary HPV screening programs, partial genotyping for HPV16/18 or high-grade triage cytology in OHR HPV positive women can be used to refer the highest risk group to colposcopy, but 12-month follow-up for women with OHR HPV and low-grade cytology is associated with a low risk of developing cervical cancer. Direct referral to colposcopy for this group would be associated with a substantial increase in colposcopy referrals and the associated harms, and is also cost-ineffective; thus, 12-month surveillance for women with OHR HPV and low-grade cytology provides the best balance between benefits, harms and cost-effectiveness.

Falls are a major cause of injury and death annually for millions of individuals 65 and older. Older adults are at risk for falls for a variety of reasons regardless of where they live. Falls are defined as any sudden drop from one surface to a lower surface. The purpose of this fall prevention evidence-based practice guideline is to describe strategies that can identify individuals at risk for falls. A 10-step protocol including screening for falls, comprehensive fall assessment, gait and balance screening when necessary, and an individualized fall intervention program addressing specific fall risks is presented. Reassessing fall risk and fall prevention programs will ensure a proactive approach to reducing falls in the aging population. [Journal of Gerontological Nursing, 43(11), 15-21.].

Korean American women have among the lowest rates of cervical cancer screening in the United States. The authors evaluated a multicomponent intervention combining community education with navigation services to reduce access barriers and increase screening rates in this underserved population. It was hypothesized that cervical cancer screening rates would be higher among women who received the intervention program compared with those in the control program. Korean American women (N = 705) were recruited from 22 churches. In this matched-pair, group-randomized design, 347 women received the intervention, which consisted of a culturally relevant cancer education program combined with provision of navigation services. The control group (N = 358) received general health education, including information about cervical cancer risk and screening and where to obtain low-cost or no-cost screening. Screening behavior was assessed 12 months after the program. Screening behavior data were obtained from 588 women 12 months after the program. In both site-level and participant-level analyses, the intervention program contributed to significantly higher screening rates compared with the control program (odds ratio [OR], 25.9; 95% confidence interval [CI], 10.1-66.1; P < .001). In sensitivity analysis, the treatment effect remained highly significant (OR, 16.7; 95% CI, 8.1-34.4; P < .001). A multicomponent intervention combining community cancer education with navigation services yielded significant increases in cervical cancer screening rates among underscreened Korean American women. Community-accessible programs that incorporate cancer education with the delivery of key navigation services can be highly effective in increasing cervical cancer screening rates in this underserved population.

Using an ounce of prevention: does it reduce health care expenditures and reap pounds of profits? A study of the financial impact of wellness and health risk screening programs.

PubMed

Phillips, Janet F

2009-01-01

As we are all well aware, health care expenditures in the United States are out of control and growing at epic proportions. Since private industry shoulders a significant burden of paying these rising health care costs, the huge and ever increasing sum paid by these corporations continues to impact the US economy translating into higher prices of services and manufactured goods and reduced job opportunities when companies outsource jobs or locate manufacturing facilities to avoid paying health care benefits for workers. As a result, health care expenditures have become a centerpiece of an enormous public policy debate as Congress is currently working on several versions of a bill to completely revise health care from the ground up. This research project was accomplished to examine the effectiveness of one approach to control rising health care costs and contain corporate financial responsibility--the establishment of wellness and health risk screening programs to improve the health of employees. Total health care cost per insured individual was gathered through an online survey directly from health care benefit administrators. The survey also asked information about wellness and health risk screening programs and the related responses were used to determine if there were a relationship between health care costs and health prevention programs. While statistical analysis was hampered in the current study because of the small sample size, some valid conclusions were reached. The study was successful in identifying a benchmark of Average Total Health Care Cost per Individual from $5,100 to $5,800 for 2005 through 2007. This is especially interesting in light of the fact that an average of $7,026 was spent on health care per person in 2006 in the United States. The study was also able to contribute an estimate of the increase realized in these expenditures of 6 percent in 2007 over 2006, and 4 percent in 2006 over 2005, which were in fact similar to the national average. The final contribution of the study is to suggest an explanation for the costs which appear to be holding their own in terms of the national average. While this cannot be statistically verified, it does seem that the active participation of these companies in wellness programs could be a factor. Wellness programs were very popular in this sample of companies as 82 percent of the respondents answered "YES" when asked if the company funds their own employee wellness program. This is an impressive number of companies that have recognized wellness programs as a potential means to reduce employee health care costs. In regards to specific programs, at least 50 percent of respondents answered that they have smoking cessation, employee fitness, counseling, health risk screening, and bio-metric screening programs. The existence of health screening variables show an impressive 73 percent of respondents do practice some sort of health care screening, 50 percent offer biometric screening while 18 percent have onsite clinics and 23 percent run annual employee fairs.

As primary HPV screening programs are rolled out, methods are needed for routine quality assurance of HPV laboratory analyzes. To explore the use of similar design for audit as currently used in cytology-based screening, to estimate the clinical sensitivity to identify women at risk for CIN 3 or worse (CIN3+). Population-based cohort study conducted within the cervical screening program in Stockholm, Sweden, in 2011-2012. All women with histopathologically confirmed CIN3+ in the following two years were identified by registry analysis. Primary HPV and cytology screening results were collected. For women who had not been HPV tested, biobanked cytology samples were HPV-tested. If the original HPV result had been negative, the sample and subsequent biopsies were analyzed with broad HPV typing (general primer PCR and Luminex). 154 women had a biobanked prediagnostic cytology sample taken up to 2 years before a histopathologically confirmed CIN3+. The high-risk HPV-positivity was 97% (148/154 women), whereas 143/154 (94%) women had had a cytological abnormality. Among the six HPV-negative samples, one sample was HPV 33 positive in repeat testing whereas the other five cases were HPV-negative also on repeat testing, but HPV-positive in the subsequent tumor tissue. A sensitivity of the HPV test that is higher than the sensitivity of cytology suggests adequate quality of the testing. Regular audits of clinical sensitivity, similar to those of cytology-based screening, should be used also in HPV-based screening programs, in order to continuously monitor the performance of the analyzes.

To identify the incremental costs and consequences of stratified national breast screening programs (stratified NBSPs) and drivers of relative cost-effectiveness. A decision-analytic model (discrete event simulation) was conceptualized to represent four stratified NBSPs (risk 1, risk 2, masking [supplemental screening for women with higher breast density], and masking and risk 1) compared with the current UK NBSP and no screening. The model assumed a lifetime horizon, the health service perspective to identify costs (£, 2015), and measured consequences in quality-adjusted life-years (QALYs). Multiple data sources were used: systematic reviews of effectiveness and utility, published studies reporting costs, and cohort studies embedded in existing NBSPs. Model parameter uncertainty was assessed using probabilistic sensitivity analysis and one-way sensitivity analysis. The base-case analysis, supported by probabilistic sensitivity analysis, suggested that the risk stratified NBSPs (risk 1 and risk-2) were relatively cost-effective when compared with the current UK NBSP, with incremental cost-effectiveness ratios of £16,689 per QALY and £23,924 per QALY, respectively. Stratified NBSP including masking approaches (supplemental screening for women with higher breast density) was not a cost-effective alternative, with incremental cost-effectiveness ratios of £212,947 per QALY (masking) and £75,254 per QALY (risk 1 and masking). When compared with no screening, all stratified NBSPs could be considered cost-effective. Key drivers of cost-effectiveness were discount rate, natural history model parameters, mammographic sensitivity, and biopsy rates for recalled cases. A key assumption was that the risk model used in the stratification process was perfectly calibrated to the population. This early model-based cost-effectiveness analysis provides indicative evidence for decision makers to understand the key drivers of costs and QALYs for exemplar stratified NBSP.

Cervical cancer is the third most common form of cancer that strikes Malaysian women. The National Cancer Registry in 2006 and 2007 reported that the age standardized incidence (ASR) of cervical cancer was 12.2 and 7.8 per 100,000 women, respectively. The cumulative risk of developing cervical cancer for a Malaysian woman is 0.9 for 74 years. Among all ethnic groups, the Chinese experienced the highest incidence rate in 2006, followed by Indians and Malays. The percentage cervical cancer detected at stage I and II was 55% (stage I: 21.0%, stage II: 34.0%, stage III: 26.0% and stage IV: 19.0%). Data from Ministry of Health Malaysia (2006) showed a 58.9% estimated coverage of pap smear screening conducted among those aged 30-49 years. Only a small percentage of women aged 50-59 and 50-65 years old were screened, 14% and 13.8% coverage, respectively. Incidence of cervical cancer was highest (71.6%) among those in the 60-65 age group (MOH, 2003). Currently, there is no organized population-based screening program available for the whole of Malaysia. A pilot project was initiated in 2006, to move from opportunistic cervical screening of women who attend antenatal and postnatal visits to a population based approach to be able to monitor the women through the screening pathway and encourage women at highest risk to be screened. The project was modelled on the screening program in Australia with some modifications to suit the Malaysian setting. Substantial challenges have been identified, particularly in relation to information systems for call and recall of women, as well as laboratory reporting and quality assurance. A cost-effective locally-specific approach to organized screening, that will provide the infrastructure for increasing participation in the cervical cancer screening program, is urgently required.

The Next Step Trial was a randomized trial of worksite colorectal cancer screening promotion and nutrition interventions for automobile industry employees at increased risk of colorectal cancer. Interventions were tested at 28 worksites with 5,042 employees. This report describes results of the screening promotion intervention. Worksites randomized to the control group received a standard program including rectal examination, fecal occult blood testing, and flexible sigmoidoscopy. Intervention worksites received an enhanced program (i.e., standard program plus an educational booklet/telephone call). Compliance (i.e., completion of all recommended screening examinations) and coverage (i.e., completion of at least one screening examination), the primary and secondary outcomes, were measured over 2 years. In the 2 years prior to baseline, 61% of employees had been screened. After random assignment, baseline differences in several employee characteristics and worksite screening procedures were detected, including more past history of screening in control worksites. After adjusting for differences, we found modest, but higher, compliance and coverage in intervention compared with control worksites (odds ratio [95% confidence limits] = 1.46 [1.1-2.0] and 1.33 [1.1, 1.6], respectively). Adding a personally tailored behavioral intervention to a standard colorectal cancer screening program can promote continued employee participation in screening as measured by compliance. Further research is needed to assess intervention effects in other populations. Copyright 1999 American Health Foundation and Academic Press.

Background High blood pressure is a leading risk factor for death and disability in sub-Saharan Africa (SSA). We evaluated the costs and cost-effectiveness of hypertension care provided within the Kwara State Health Insurance (KSHI) program in rural Nigeria. Methods A Markov model was developed to assess the costs and cost-effectiveness of population-level hypertension screening and subsequent antihypertensive treatment for the population at-risk of cardiovascular disease (CVD) within the KSHI program. The primary outcome was the incremental cost per disability-adjusted life year (DALY) averted in the KSHI scenario compared to no access to hypertension care. We used setting-specific and empirically-collected data to inform the model. We defined two strategies to assess eligibility for antihypertensive treatment based on 1) presence of hypertension grade 1 and 10-year CVD risk of >20%, or grade 2 hypertension irrespective of 10-year CVD risk (hypertension and risk based strategy) and 2) presence of hypertension in combination with a CVD risk of >20% (risk based strategy). We generated 95% confidence intervals around the primary outcome through probabilistic sensitivity analysis. We conducted one-way sensitivity analyses across key model parameters and assessed the sensitivity of our results to the performance of the reference scenario. Results Screening and treatment for hypertension was potentially cost-effective but the results were sensitive to changes in underlying assumptions with a wide range of uncertainty. The incremental cost-effectiveness ratio for the first and second strategy respectively ranged from US$ 1,406 to US$ 7,815 and US$ 732 to US$ 2,959 per DALY averted, depending on the assumptions on risk reduction after treatment and compared to no access to antihypertensive treatment. Conclusions Hypertension care within a subsidized private health insurance program may be cost-effective in rural Nigeria and public-private partnerships such as the KSHI program may provide opportunities to finance CVD prevention care in SSA.

There are significant racial disparities in stroke incidence and mortality. Health fairs and outreach programs can be used to increase stroke literacy, but they often fail to reach those at highest risk, including African American males. We conducted a stroke outreach and screening program at an inner city market in order to attract a high-risk group for a stroke education intervention. A modified Framingham risk tool was used to estimate stroke risk and a 10-item quiz was developed to assess stroke literacy among 80 participants. We report results of the demographic and stroke risk analyses and stroke knowledge assessment. The program attracted a majority male (70%) and African American (95%) group of participants. Self-reported hypertension (57.5%), tobacco use (40%), and diabetes (23.8%) were prevalent. Knowledge of stroke warning signs, risk factors, and appropriate action to take for stroke symptoms was not poor when compared to the literature. Stroke outreach and screening in an inner city public market may be an effective way to target a high-risk population for stroke prevention interventions. Stroke risk among participants was high despite adequate stroke knowledge.

Burden of colorectal cancer is rising in China. More attention and financial input have been paid to it by central government that colorectal cancer screening program has been carried out recently in many areas in China. Diversity of screening strategies and limited health resources render selecting the best strategy in a population-wide program a challenging task that economy was also required to be considered except safety and efficacy. To provide a reference for the subsequent further economic evaluation, here we reviewed the evidence available on the economic evaluation of colorectal cancer screening in China. Meanwhile, information related to screening strategies, participation and mid-term efficacy of screening, information and results on economic evaluation were extracted and summarized. Three of the four studies finally included evaluated strategies combining immunochemical fecel occult blood test (iFOBT) with high-risk factor questionnaire as initial screening, colonoscopy as diagnostic screening. There was a consensus regarding the efficacy and effectiveness of screening compared to no screening. Whereas the lack and poor comparability between studies, multi-perspective and multi-phase economic evaluation of colorectal cancer screening is needed, relying on current population-based screening program to conduct a comprehensive cost accounting.

Purpose: To conduct and evaluate a two-phased community-based approach to recruit lower socioeconomic status, minority, or Spanish-speaking adults at risk of developing diabetes to a randomized trial of a lifestyle intervention program delivered by a public health department. Design: Within geographic areas comprising our target population, 4 community organizations provided local space for conducting the study and program. Phase I—outreach in venues surrounding these organizations—included diabetes education, a short diabetes risk appraisal (DRA), and diabetes risk screening based on a fasting fingerstick glucose test. Phase II—trial recruitment—began concurrently for those found to be at risk of developing diabetes in Phase I by explaining the study, lifestyle program, and research process. Those interested and eligible enrolled in the 1-year study. Results: Over 2 years, approximately 5,110 individuals received diabetes education, 1,917 completed a DRA, and 1,164 were screened of which 641 (55%) had an elevated fingerstick result of ≥106 mg/dl. Of the study sampling frame—persons over age 25 at risk of developing diabetes (N = 544)—238 (43%) enrolled in the trial; of those who were study eligible (n = 427), 56% enrolled. In the final sample, mean age was 56 years (SD = 17), 78% were ethnic minorities, 32% were Spanish-speaking, and 15% had a high school education or less. Implications: Providing diabetes health education and screening prior to study recruitment may help overcome barriers to research participation in underserved communities, thus helping address difficulties recruiting minority and older populations into research, particularly research pertaining to chronic disease risk factors.

2015-01-01

The current study identified psychosocial variables associated with AUDIT-C hazardous drinking risk status for male and female college students. Logistic regression analysis revealed that AUDIT-C risk status was associated with alcohol-related negative consequences, injunctive norms, and descriptive norms for both male and female participants. Sociability and self-perception outcome expectancies predicted risk status for females. Cognitive and behavioral impairment expectancies predicted risk status for men in the sample. Implications for screening and brief intervention programming efforts are discussed. © The Author(s) 2015.

Given the uncertain cost of delivering community-based cancer screening programs, we developed a Markov simulation model to project the budget impact of implementing a comprehensive colorectal cancer (CRC) prevention program compared with the status quo. The study modeled the impacts on the costs of clinical services, materials, and staff expenditures for recruitment, education, fecal immunochemical testing (FIT), colonoscopy, follow-up, navigation, and initial treatment. We used data from the Against Colorectal Cancer In Our Neighborhoods comprehensive CRC prevention program implemented in El Paso, Texas, since 2012. We projected the 3-year financial consequences of the presence and absence of the CRC prevention program for a hypothetical population cohort of 10,000 Hispanic medically underserved individuals. The intervention cohort experienced a 23.4% higher test completion rate for CRC prevention, 8 additional CRC diagnoses, and 84 adenomas. The incremental 3-year cost was $1.74 million compared with the status quo. The program cost per person was $261 compared with $86 for the status quo. The costs were sensitive to the proportion of high-risk participants and the frequency of colonoscopy screening and diagnostic procedures. The budget impact mainly derived from colonoscopy-related costs incurred for the high-risk group. The effectiveness of FIT to detect CRC was critically dependent on follow-up after positive FIT. Community cancer prevention programs need reliable estimates of the cost of CRC screening promotion and the added budget impact of screening with colonoscopy.

Due to early detection of mental ill-health being an important suicide preventive strategy, the multi-centre EU funded "Saving and Empowering Young Lives in Europe" (SEYLE) study compared three school-based mental health promotion programs to a control group. In France, 1007 students with a mean age of 15.2 years were recruited from 20 randomly assigned schools. This paper explores the French results of the SEYLE's two-stage screening program (ProfScreen) and of the cross-program suicidal emergency procedure. Two-hundred-thirty-five ProfScreen students were screened using 13 psychopathological and risk behaviour scales. Students considered at risk because of a positive finding on one or more scales were offered a clinical interview and, if necessary, referred for treatment. A procedure for suicidal students (emergency cases) was set up to detect emergencies in the whole cohort (n = 1007). Emergency cases were offered the same clinical interview as the ProfScreen students. The interviewers documented their reasons for referrals in a short report. 16,2% of the ProfScreen students (38/235) were referred to treatment and 2,7% of the emergency cases (27/1007) were also referred to treatment due to high suicidal risk. Frequent symptoms in those students referred for evaluation were depression, alcohol misuse, non-suicidal self-injuries (NSSI), and suicidal behaviours. According to the multivariate regression analysis of ProfScreen, the results show that the best predictors for treatment referral were NSSI (OR 2.85), alcohol misuse (OR 2.80), and depressive symptoms (OR 1.13). Analysis of the proportion for each scale of students referred to treatment showed that poor social relationships (60%), anxiety (50%), and suicidal behaviours (50%) generated the highest rate of referrals. Qualitative analysis of clinician's motivations to refer a student to mental health services revealed that depressive symptoms (51%), anxiety (38%), suicidal behaviours (40%), and negative life events (35%) were the main reasons for referrals. Thus, not only the classical psychopathological symptoms, such as depression, anxiety, and suicidal behaviours, but also negative life events and poor social relationships (especially isolation) motivate referrals for treatment.

This paper describes FitKids360, a stage 2 pediatric weight management program. FitKids360 is a physician-referred, multicomponent, low-cost healthy lifestyle program for overweight and obese youth 5-16 years of age and their families. FitKids360 provides an evidence-based approach to the treatment of pediatric overweight by targeting patients' physical activity, screen time, and dietary behaviors using a family-centered approach. The intervention begins with a two-hour orientation and assessment period followed by six weekly sessions. Assessments include lifestyle behaviors, anthropometry, and the Family Nutrition and Physical Activity (FNPA) survey, which screens for obesogenic risk factors in the home environment. Outcomes are presented from 258 patients who completed one of 33 FitKids360 classes. After completing FitKids360, patients increased moderate to vigorous physical activity by 14 minutes (P = 0.019), reduced screen time by 44 minutes (P < 0.001), and improved key dietary behaviors. Overall, FNPA scores increased by 9% (P < 0.001) and 69% of patients with "high risk" FNPA scores at baseline dropped below the "high risk" range by followup. Patients also lowered BMIs (P = 0.011) and age- and sex-adjusted BMI z-scores (P < 0.001) after completing the 7-week program. We hope this report will be useful to medical and public health professionals seeking to develop stage 2 pediatric obesity programs.

Lung cancer screening may provide a "teachable moment" for promoting smoking cessation. This study assessed smoking cessation and relapse rates among individuals undergoing follow-up low-dose chest computed tomography (CT) in a clinical CT lung screening program and assessed the influence of initial screening results on smoking behavior. Self-reported smoking status for individuals enrolled in a clinical CT lung screening program undergoing a follow-up CT lung screening exam between 1st February, 2014 and 31st March, 2015 was retrospectively reviewed and compared to self-reported smoking status using a standardized questionnaire at program entry. Point prevalence smoking cessation and relapse rates were calculated across the entire population and compared with exam results. All individuals undergoing screening fulfilled the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology: Lung Cancer Screening v1.2012(®) high-risk criteria and had an order for CT lung screening. A total of 1,483 individuals underwent a follow-up CT lung screening exam during the study interval. Smoking status at time of follow-up exam was available for 1,461/1,483 (98.5%). A total of 46% (678/1,461) were active smokers at program entry. The overall point prevalence smoking cessation and relapse rates were 20.8% and 9.3%, respectively. Prior positive screening exam results were not predictive of smoking cessation (OR 1.092; 95% CI, 0.715-1.693) but were predictive of reduced relapse among former smokers who had stopped smoking for 2 years or less (OR 0.330; 95% CI, 0.143-0.710). Duration of program enrollment was predictive of smoking cessation (OR 0.647; 95% CI, 0.477-0.877). Smoking cessation and relapse rates in a clinical CT lung screening program rates are more favorable than those observed in the general population. Duration of participation in the screening program correlated with increased smoking cessation rates. A positive exam result correlated with reduced relapse rates among smokers recently quit smoking.

It is estimated that millions of North Americans would qualify for lung cancer screening and that billions of dollars of national health expenditures would be required to support population-based computed tomography lung cancer screening programs. The decision to implement such programs should be informed by data on resource utilization and costs. Resource utilization data were collected prospectively from 2059 participants in the Pan-Canadian Early Detection of Lung Cancer Study using low-dose computed tomography (LDCT). Participants who had 2% or greater lung cancer risk over 3 years using a risk prediction tool were recruited from seven major cities across Canada. A cost analysis was conducted from the Canadian public payer's perspective for resources that were used for the screening and treatment of lung cancer in the initial years of the study. The average per-person cost for screening individuals with LDCT was $453 (95% confidence interval [CI], $400-$505) for the initial 18-months of screening following a baseline scan. The screening costs were highly dependent on the detected lung nodule size, presence of cancer, screening intervention, and the screening center. The mean per-person cost of treating lung cancer with curative surgery was $33,344 (95% CI, $31,553-$34,935) over 2 years. This was lower than the cost of treating advanced-stage lung cancer with chemotherapy, radiotherapy, or supportive care alone, ($47,792; 95% CI, $43,254-$52,200; p = 0.061). In the Pan-Canadian study, the average cost to screen individuals with a high risk for developing lung cancer using LDCT and the average initial cost of curative intent treatment were lower than the average per-person cost of treating advanced stage lung cancer which infrequently results in a cure.

We present the preliminary results of the implementation of RADAR: a community suicide prevention program in adolescents implemented in two high schools in a south region of Chile. In a pilot study, during 2016, we implemented RADAR in two high schools of Puerto Aysen, in in the Region of Aysen of Chile. A total of 409 actors were trained (among students, school teachers, caregivers and health professionals) for the screening and referral of high suicide risk adolescents. Out of a total of 144 students who passed the RADAR screening systems, 29 cases were detected as suicide risk (20%) and 27 of them were opportunely referred to the Emergency Service of the Hospital of Puerto Aysen. In the second RADAR screening campaign, 3 months later, 90% of the cases no longer presented suicide risk. These results show the high proportion of ado lescents at risk of suicide who are not visible by the health system and the feasibility of implementing RADAR in the community as an effective suicide prevention intervention.

Modeling Precheck Parallel Screening Process in the Face of Strategic Applicants with Incomplete Information and Screening Errors.

In security check systems, tighter screening processes increase the security level, but also cause more congestion, which could cause longer wait times. Having to deal with more congestion in lines could also cause issues for the screeners. The Transportation Security Administration (TSA) Precheck Program was introduced to create fast lanes in airports with the goal of expediting passengers who the TSA does not deem to be threats. In this lane, the TSA allows passengers to enjoy fewer restrictions in order to speed up the screening time. Motivated by the TSA Precheck Program, we study parallel queueing imperfect screening systems, where the potential normal and adversary participants/applicants decide whether to apply to the Precheck Program or not. The approved participants would be assigned to a faster screening channel based on a screening policy determined by an approver, who balances the concerns of safety of the passengers and congestion of the lines. There exist three types of optimal normal applicant's application strategy, which depend on whether the marginal payoff is negative or positive, or whether the marginal benefit equals the marginal cost. An adversary applicant would not apply when the screening policy is sufficiently large or the number of utilized benefits is sufficiently small. The basic model is extended by considering (1) applicants' parameters to follow different distributions and (2) applicants to have risk levels, where the approver determines the threshold value needed to qualify for Precheck. This article integrates game theory and queueing theory to study the optimal screening policy and provides some insights to imperfect parallel queueing screening systems. © 2017 Society for Risk Analysis.

Predictive features of breast cancer on Mexican screening mammography patients

Breast cancer is the most common type of cancer worldwide. In response, breast cancer screening programs are becoming common around the world and public programs now serve millions of women worldwide. These programs are expensive, requiring many specialized radiologists to examine all images. Nevertheless, there is a lack of trained radiologists in many countries as in Mexico, which is a barrier towards decreasing breast cancer mortality, pointing at the need of a triaging system that prioritizes high risk cases for prompt interpretation. Therefore we explored in an image database of Mexican patients whether high risk cases can be distinguished using image features. We collected a set of 200 digital screening mammography cases from a hospital in Mexico, and assigned low or high risk labels according to its BIRADS score. Breast tissue segmentation was performed using an automatic procedure. Image features were obtained considering only the segmented region on each view and comparing the bilateral di erences of the obtained features. Predictive combinations of features were chosen using a genetic algorithms based feature selection procedure. The best model found was able to classify low-risk and high-risk cases with an area under the ROC curve of 0.88 on a 150-fold cross-validation test. The features selected were associated to the differences of signal distribution and tissue shape on bilateral views. The model found can be used to automatically identify high risk cases and trigger the necessary measures to provide prompt treatment.

Outcomes of an International Workshop on Preconception Expanded Carrier Screening: Some Considerations for Governments.

Consideration of expanded carrier screening has become an emerging issue for governments. However, traditional criteria for decision-making regarding screening programs do not incorporate all the issues relevant to expanded carrier screening. Further, there is a lack of consistent guidance in the literature regarding the development of appropriate criteria for government assessment of expanded carrier screening. Given this, a workshop was held to identify key public policy issues related to preconception expanded carrier screening, which governments should consider when deciding whether to publicly fund such programs. In June 2015, a satellite workshop was held at the European Society of Human Genetics Conference. It was structured around two design features: (1) the provision of information from a range of perspectives and (2) small group deliberations on the key issues that governments need to consider and the benefits, risks, and challenges of implementing publicly funded whole-population preconception carrier screening. Forty-one international experts attended the workshop. The deliberations centered primarily on the conditions to be tested and the elements of the screening program itself. Participants expected only severe conditions to be screened but were concerned about the lack of a consensus definition of "severe." Issues raised regarding the screening program included the purpose, benefits, harms, target population, program acceptability, components of a program, and economic evaluation. Participants also made arguments for consideration of the accuracy of screening tests. A wide range of issues require careful consideration by governments that want to assess expanded carrier screening. Traditional criteria for government decision-making regarding screening programs are not a "best fit" for expanded carrier screening and new models of decision-making with appropriate criteria are required. There is a need to define what a "severe" condition is, to build evidence regarding the reliability and accuracy of screening tests, to consider the equitable availability and downstream effects on and costs of follow-up interventions for those identified as carriers, and to explore the ways in which the components of a screening program would be impacted by unique features of expanded carrier screening.

Introduction. The objectives of this systematic review were to evaluate the evidence for different CRC screening tests and to determine the most appropriate ages of initiation and cessation for CRC screening and the most appropriate screening intervals for selected CRC screening tests in people at average risk for CRC. Methods. Electronic databases were searched for studies that addressed the research objectives. Meta-analyses were conducted with clinically homogenous trials. A working group reviewed the evidence to develop conclusions. Results. Thirty RCTs and 29 observational studies were included. Flexible sigmoidoscopy (FS) prevented CRC and led to the largest reduction in CRC mortality with a smaller but significant reduction in CRC mortality with the use of guaiac fecal occult blood tests (gFOBTs). There was insufficient or low quality evidence to support the use of other screening tests, including colonoscopy, as well as changing the ages of initiation and cessation for CRC screening with gFOBTs in Ontario. Either annual or biennial screening using gFOBT reduces CRC-related mortality. Conclusion. The evidentiary base supports the use of FS or FOBT (either annual or biennial) to screen patients at average risk for CRC. This work will guide the development of the provincial CRC screening program.

Routine screening for breast and cervical cancers lowers mortality from these diseases, but the benefit has not permeated to Native American women, for whom the five-year survival rate is the lowest of any population group in the United States. To help address this problem, an educational/training program was designed to enhance the skills of nurses and other health service providers and develop clinic support systems to better recruit, screen, and follow clients for breast and cervical cancer screening services. A total of 131 nurses participated in the training program at 33 different sites between 1995 and 2000. Prior to and following training, each participant was given a questionnaire to determine knowledge of breast and cervical cancer screening techniques and recommendations, cancer survival and risk factors, and situational scenarios. The average score for the pretest was 54% correct. The posttest average was 89% correct. The percent correct increased 35% from pre- to posttest (p < 0.001). The knowledge to implement a successful screening program can be acquired through the current curriculum.

To present the largest cohort of preschool children screened by the MTI PhotoScreener over a 9-year period from a single, statewide vision screening effort. Cross-sectional study. We included 147,809 children screened between May 1, 2000, and April 30, 2009 by a photoscreening program. Retrospective review of results from the Iowa photoscreening program using the MTI PhotoScreener. The photographs were taken by volunteers from local Lions clubs and sent to the University of Iowa for interpretation. Children who failed the photoscreening were referred to local eye care professionals, who preformed a comprehensive eye evaluation and forwarded the results to the Iowa KidSight program. Number of screenings, referral rate, positive predictive value (PPV), follow-up rate, and associated costs per year are described. Over the 9 years of the continuously operating program, 147,809 children underwent photoscreens to detect amblyopic risk factors at 9746 sites. Because of abnormal photoscreen results, 6247 children (4.2%) were referred. Of the children, 24.3% were evaluated by local ophthalmologists and 76.7% were seen by local optometrists. Between 2000 and 2009, the follow-up rate ranged from a low of 36.1% to a high of 89.5%, with an overall program follow-up rate after the addition of the follow-up coordinator of 81.3%. The overall PPV of the MTI PhotoScreener was 94.2%. Taking into account overall operating budget including salaries and associated costs, the cost of screening 1 child has been reduced to $US9 per child. The addition of a part-time follow-up coordinator to the photoscreening program produced 89.5% follow-up rate when screening 147,809 children for amblyopia risk factors over a 9-year period.

Women with false-positive results are commonly referred back to routine screening. Questions remain regarding their long-term outcome of breast cancer. We assessed the risk of screen-detected breast cancer in women with false-positive results. We conducted a joint analysis using individual level data from the population-based screening programs in Copenhagen and Funen in Denmark, Norway, and Spain. Overall, 150,383 screened women from Denmark (1991-2008), 612,138 from Norway (1996-2010), and 1,172,572 from Spain (1990-2006) were included. Poisson regression was used to estimate the relative risk (RR) of screen-detected cancer for women with false-positive versus negative results. We analyzed information from 1,935,093 women 50-69 years who underwent 6,094,515 screening exams. During an average 5.8 years of follow-up, 230,609 (11.9%) women received a false-positive result and 27,849 (1.4%) were diagnosed with screen-detected cancer. The adjusted RR of screen-detected cancer after a false-positive result was 2.01 (95% CI: 1.93-2.09). Women who tested false-positive at first screen had a RR of 1.86 (95% CI: 1.77-1.96), whereas those who tested false-positive at third screening had a RR of 2.42 (95% CI: 2.21-2.64). The RR of breast cancer at the screening test after the false-positive result was 3.95 (95% CI: 3.71-4.21), whereas it decreased to 1.25 (95% CI: 1.17-1.34) three or more screens after the false-positive result. Women with false-positive results had a twofold risk of screen-detected breast cancer compared to women with negative tests. The risk remained significantly higher three or more screens after the false-positive result. The increased risk should be considered when discussing stratified screening strategies. © 2016 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Incidences of UV-induced skin cancer are continuously increasing. For this reason, early diagnosis is becoming more important. In this study, 783 employees of a technical company participated in an employee skin cancer screening program, which consisted of a physical examination for benign and malignant skin lesions and premalignant conditions. To ensure the quality of the examinations, screening was only performed by 5 trained dermatologists. Participants also were asked to complete a standardized questionnaire prior to examination. A total of 661 skin lesions were diagnosed among 48% of participants; 12.8% of participants exhibited 50 or more melanocytic nevi and the risk for developing skin cancer was categorized as at least moderate for 64.9%. Additionally, 84.4% of participants with at least 1 skin lesion were advised to have a checkup within 1 year. The high rate of suspicious nevi detected in this study suggested that employee skin cancer screening programs are effective and also should be recommended at companies where employees are not at increased risk for developing skin cancer due to the nature of their work (eg, those who work outdoors). Despite the comparatively selective and young study population, these examinations provide evidence of the importance of skin cancer screening for the wider population.

Most trauma surgeons are unfamiliar with screening, brief intervention, and referral (SBIR) programs for substance use disorders, and few trauma centers provide them. This report describes how an urban private-teaching hospital adapted a protocol from an existing emergency department-based program to include patients treated by the trauma service. We recorded the rates of SBIR completion and reasons for failure during each phase of the implementation, interviewed trauma service staff and health educators to assess attitudes toward the program, and evaluated patient satisfaction surveys. By adding SBIR staff to the trauma outpatient clinic and to trauma morning rounds, the capture rate increased from 12 to 71%. Most screened patients (59%) were found at risk for problems or probably dependent on alcohol or drugs. Trauma service staff and health educators reported high satisfaction with the program. Patients reported higher satisfaction with SBIR. SBIR services can be effectively integrated into all components of a busy, urban trauma service by adding specially trained health educators to the trauma service staff. This collaboration provides effective SBIR services to both trauma and emergency service patients without interfering with patient flow or medical procedures. The relatively high percentage of patients at risk for alcohol or drug problems supports the inclusion of routine alcohol and drug screening for all eligible trauma patients.

Service Use by At-Risk Youth after School-Based Suicide Screening

2009-01-01

Objective We sought to examine follow-up service use by students identified at risk for suicidal behavior in a school-based screening program, and assess barriers to seeking services as perceived by youth and parents. Method We conducted a longitudinal study of 317 at-risk youth identified by a school-based suicide screening in six high schools in New York State. The at-risk teenagers and their parents were interviewed approximately two years after the initial screen to assess service use during the intervening period and identify barriers that may have interfered with seeking treatment. Results At the time of the screen, 72% of the at-risk students were not receiving any type of mental health service. Of these students, 51% were deemed in need of services and subsequently referred by us to a mental health professional. Nearly 70% followed through with the screening’s referral recommendations. Youth and their parents reported perceptions about mental health problems, specifically relating to the need for treatment, as the primary reasons for not seeking service. Conclusions Screening appears to be effective in enhancing the likelihood that students at risk for suicidal behavior will get into treatment. Well developed and systematic planning is needed to ensure that screening and referral services are coordinated so as to facilitate access for youth into timely treatment. PMID:19858758

We examined the long-term effects of two interventions designed to reduce sexual risk behavior among African American adolescents. African American adolescents (N = 1383, ages 14-17) were recruited from community-based organizations over a period of 16 months in two northeastern and two southeastern mid-sized U.S. cities with high rates of sexually transmitted infection (STI). Participants were screened for three STIs (gonorrhea, chlamydia, and trichomoniasis) and completed an audio computer-assisted attitude, intention, and behavior self-interview. Youth who tested positive for an STI (8.3%) received treatment and risk reduction counseling. In addition, television and radio HIV-prevention messages were delivered during the recruitment period and 18 months of follow-up in one randomly selected city in each region. Analyses determined effects of the media program for those receiving a positive versus negative STI test result on number of sexual partners and occurrence of unprotected sex. Adolescents who tested STI-positive reduced their number of vaginal sex partners and the probability of unprotected sex over the first 6 months. However, in the absence of the mass media program, adolescents returned to their previously high levels of sexual risk behavior after 6 months. Adolescents who tested STI-positive and received the mass media program showed more stable reductions in unprotected sex. Community-based STI treatment and counseling can achieve significant, but short-lived reductions in sexual risk behavior among STI-positive youth. A culturally sensitive mass media program has the potential to achieve more stable reductions in sexual risk behavior and can help to optimize the effects of community-based STI screening.

Prevention. How much harm? How much benefit? 3. Physical, psychological and social harm.

PubMed Central

Marshall, K G

1996-01-01

Harm caused by preventive programs may be physical, psychological, social or, if informed consent has not been obtained, ethical. Adverse effects of preventive screening programs may occur at any of the three levels of the "screening cascade", the screening procedure itself, the investigation of abnormal results of screening tests or the treatment of detected abnormalities or diseases. The greatest harm occurs at the second and third levels. Examples of procedures that may cause physical harm are venipuncture, mammography, colonoscopy, breast biopsy, transrectal ultrasonography, prostate biopsy, weight-reducing and cholesterol-lowering diets and radical prostatectomy. The psychological and social harm of preventive programs involves anticipated discomfort or perception of adverse effects of preventive interventions; unpleasant interactions with health care workers, time required for preventive programs, excessive overall awareness of health, anxiety over the results of a screening test implications of a positive screening test, consequences of being labelled as "sick" or "at risk," psychopathologic effects induced directly by preventive programs and, in the case of a false-negative test result, false assurance of disease-free status. Since the positive predictive value of screening tests in the general population is always low, most abnormal test results are "false-positive," these engender a great deal of psychological discuss among patients.

Methicillin-resistant Staphylococcus aureus (MRSA) poses an increasingly large disease and economic burden worldwide. The effectiveness of screening programs in the tropics is poorly understood. The aims of this study are: (i) to analyze the factors affecting MRSA colonization at admission and acquisition during hospitalization and (ii) to evaluate the cost-effectiveness of a screening program which aims to control MRSA incidence during hospitalization. We conducted a retrospective case-control study of patients admitted to the Communicable Disease Centre (CDC) in Singapore between Jan 2009 and Dec 2010 when there was an ongoing selective screening and isolation program. Risk factors contributing to MRSA colonization on admission and acquisition during hospital stay were evaluated using a logistic regression model. In addition, a cost-effectiveness analysis was conducted to determine the cost per disability-adjusted life year (DALY) averted due to implementing the screening and isolation program. The average prevalence rate of screened patients at admission and the average acquisition rate at discharge during the study period were 12.1 and 4.8 % respectively. Logistic regression models showed that older age (adjusted odds ratio (OR) 1.03, 95 % CI 1.02-1.04, p < 0.001) and dermatological conditions (adjusted OR 1.49, 95 % CI 1.11-1.20, p = 0.008) were independently associated with an increased risk of MRSA colonization at admission. Age (adjusted OR 1.02, 95 % CI 1.01-1.03, p = 0.002) and length of stay in hospital (adjusted OR 1.04, 95 % CI 1.03-1.06, p < 0.001) were independent factors associated with MRSA acquisition during hospitalization. The screening and isolation program reduced the acquisition rate by 1.6 % and was found to be cost saving. For the whole study period, the program cost US$129,916, while it offset hospitalization costs of US$103,869 and loss of productivity costs of US$50,453 with -400 $/DALY averted. This study is the first to our knowledge that evaluates the cost-effectiveness of screening and isolation of MRSA patients in a tropical country. Another unique feature of the analysis is the evaluation of acquisition rates among specific types of patients (dermatological, HIV and infectious disease patients)and the comparison of the cost-effectiveness of screening and isolation between them. Overall our results indicate high MRSA prevalence that can be cost effectively reduced by selective screening and isolation programs in Singapore.

This paper investigates the impact of a 'free drug program' on the market equilibrium of drugs. We introduce a screening model of the hard drug market in which dealers use payment and punishment options to screen between high and low risk users. We show that, if a free drug program selects sufficiently many high-risk drug users, the pure-strategy separating market equilibrium ceases to exist and a symmetric mixed-strategy equilibrium results, in which drug users derive a higher expected utility. This encourages new drug users to enter the market. The novelty of the paper is the transmission mechanism for this effect, which is via the influence on market price.

To develop, pilot and determine the feasibility of a sleep-specific screening and awareness program in community pharmacies. The screening was piloted in five Australian community pharmacies. The Pharmacy Tool for Assessment of Sleep Health was constructed by drawing on known relationships between sleep disorders, and lifestyle factors, medical conditions and medications. Four validated instruments were used in the screening tool: the Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), Multivariable Apnea Prediction Index (MAPI) and International Restless Legs Syndrome Study Group Screening Criteria (IRLS). These instruments were used to predict the participant's risk of a sleep disorder and the results were compared with reported lifestyle, medical and medication factors. On-site training of consenting pharmacists was provided, followed by an eight week client recruiting and screening period. Feedback was elicited from participating pharmacists and clients. The feasibility of, and trends found from, the developed screening tool and protocol. Of 167 clients who requested or were invited to participate by pharmacists, 84 (50.3%) were screened. Analysis of collected data indicated that 33.3%, 21.4% and 27.4% of participants were at risk of having or developing insomnia, obstructive sleep apnea (OSA) and restless legs syndrome (RLS) respectively, while 38.1% were not at risk of any of the screened disorders. OSA odds increased 12.8 times (95% CI: 3.2-50.4) with diabetes and 4.9 times (1.2-20.9) with opioid use, while shift workers were 8.4 times (1.6-43.2) more likely to have insomnia. Participants and pharmacists reported the screening protocol and instrument was user friendly and feasible. The development and pilot of this screening tool was successful. The prevalence of sleep disorders in the sampled population was high but generally consistent with previous studies on the general population. Furthermore, associations found may form a foundation for a clinical algorithm to identify those at a higher risk of having or developing a sleep disorder. Further work is required to validate this screening tool in the community pharmacy context.

Whereas high risk groups such as asylum seekers are systematically screened for active tuberculosis (TB) upon entry in Switzerland, this strategy does not apply to homeless persons despite a reported high risk. Geneva health and social authorities implemented an intersectoral project to screen for active TB in homeless persons. We aimed to assess acceptability of this program and prevalence of active TB in this group. This prospective study targeted all homeless adults registering for shelter accommodation in Geneva during winter 2015. Applicants were proposed a questionnaire-based screening ( www.tb-screen.ch ) exploring epidemiological and clinical risk factors for active TB. Participants with a positive score underwent diagnostic procedures at Geneva University Hospital. Enhanced TB surveillance targeting homeless persons in the community was continued 3 months after the study termination. Overall, 726/832 (87.3%) homeless persons accepted the screening procedure. Most were young male migrants without access to care in Switzerland. Male gender (adjusted OR: 2.14; 95% confidence interval: 1.27-3.62), age below 25 years (aOR: 4.16; 95% CI: 1.27-13.64) and short duration of homelessness (aOR: 1.75; 95% CI: 1.06-2.87) were predictors of acceptance. Thirty (4.1%) had positive screening scores but none of the 24 who underwent further testing had active TB. Post-study surveillance did not identify any incident case in Geneva. Active TB screening targeting highly mobile homeless persons in shelters was well accepted and feasible. The participants' sociodemographic profile highlighted the heterogeneity of homeless groups in Europe and the null TB prevalence the variability of their active TB risks. These findings underline the feasibility of health programs targeting this hard to reach group and the need for close monitoring of this social group considering the rapid changes in international mobility patterns to tailor preventive and screening strategies to the local context.

To investigate hepatocellular carcinoma screening utilisation and factors associated with utilisation among patients prescribed hepatitis B virus anti-viral therapy and at risk of hepatocellular carcinoma. The incidence of hepatocellular carcinoma has increased in Australia over the past three decades with chronic hepatitis B virus infection a major contributor. hepatocellular carcinoma surveillance programs aim to detect cancers early enabling curative treatment options, longer survival and longer times to recurrence. Multi-site cross-sectional survey. An online study questionnaire was administered to eligible participants attending three Sydney tertiary hospitals. Data were grouped into six mutually exclusive hepatocellular carcinoma risk factor categories as per American Association for the Study of Liver Diseases guidelines. All analyses were undertaken in STATA. Logistic regression was used to assess the associations between covariates and screening utilisation. Multivariate models described were assessed using the Hosmer-Lemeshow goodness of fit. Of the 177 participants, 137 (77.4%) self-reported that US had been performed in the last six months. Awareness that screening should be performed and knowing the correct frequency of US screening were independently associated with screening utilisation. Participants who knew that screening should be undertaken were three times more likely to have had pretreatment education or were prescribed hepatitis B virus anti-viral treatment for >4 years. Participants reporting a family history of hepatocellular carcinoma were less likely to know that screening should be undertaken every 6 months. While utilisation of hepatocellular carcinoma surveillance programs was higher in this study than in previous reports, strategies to further improve surveillance remain necessary. Findings from this research form the basis for proposing strategies to improve utilisation of hepatocellular carcinoma screening, inform hepatitis B virus-related clinical practice and for the delivery of care and nursing education to people receiving hepatitis B virus anti-viral therapy and at risk of developing hepatocellular carcinoma. © 2018 John Wiley & Sons Ltd.

Objective To determine which combination of risk factors from Community Care of North Carolina’s (CCNC) Pregnancy Medical Home (PMH) risk screening form was most predictive of preterm birth (PTB) by parity and race/ethnicity. Methods This retrospective cohort included pregnant Medicaid patients screened by the PMH program before 24 weeks gestation who delivered a live birth in North Carolina between September 2011-September 2012 (N=15,428). Data came from CCNC’s Case Management Information System, Medicaid claims, and birth certificates. Logistic regression with backward stepwise elimination was used to arrive at the final models. To internally validate the predictive model, we used bootstrapping techniques. Results The prevalence of PTB was 11%. Multifetal gestation, a previous PTB, cervical insufficiency, diabetes, renal disease, and hypertension were the strongest risk factors with odds ratios ranging from 2.34 to 10.78. Non-Hispanic black race, underweight, smoking during pregnancy, asthma, other chronic conditions, nulliparity, and a history of a low birth weight infant or fetal death/second trimester loss were additional predictors in the final predictive model. About half of the risk factors prioritized by the PMH program remained in our final model (ROC=0.66). The odds of PTB associated with food insecurity and obesity differed by parity. The influence of unsafe or unstable housing and short interpregnancy interval on PTB differed by race/ethnicity. Conclusions Evaluation of the PMH risk screen provides insight to ensure women at highest risk are prioritized for care management. Using multiple data sources, salient risk factors for PTB were identified, allowing for better-targeted approaches for PTB prevention. PMID:26112751

The Effect of Personal Characteristics, Perceived Threat, Efficacy and Breast Cancer Anxiety on Breast Cancer Screening Activation

In order to activate women to participate in breast cancer screening programs, a good understanding is needed of the personal characteristics that influence how women can be activated to search for more information, consult friends and doctors, and participate in breast cancer screening programs. In the current study, we investigate the effect of six personal characteristics that have in previous research been identified as important triggers of health behavior on breast cancer screening activation: Health awareness, Need for Cognition, Affect Intensity, Breast cancer knowledge, Topic involvement, and the Perceived breast cancer risk. We test the effect of these factors on four activation variables: intention of future information seeking, forwarding the message to a friend, talking to a doctor, and actual breast cancer screening attendance. Additionally, we try to unravel the process by means of which the antecedents (the six personal characteristics) lead to activation. To that end, we test the mediating role of perceived breast cancer threat, perceived efficacy of screening, and the evoked breast cancer anxiety as mediators in this process. The data were collected by means of a cross-sectional survey in a sample of 700 Flemish (Belgium) women who were invited to the free-of-charge breast cancer population screening. Screening attendance of this sample was provided by the government agency in charge of the organisation of the screening. Health awareness, affects intensity, topic involvement, and perceived risk have the strongest influence on activation. Breast cancer anxiety and perceived breast cancer threat have a substantial mediation effect on these effects. Efficacy perceptions are less important in the activation process. Increased health awareness and a higher level of perceived risk lead to less participation in the free of charge population based breast screening program. Implications for theory and practice are offered. The limitation of the study is that only a standard invitation message was used. In future research, other types of awareness and activation messages should be tested. Additionally, the analysis could be refined by investigating the potentially different activation process in different subgroups of women. PMID:28953261

To use health economics methodology to assess the screening program on gastric cancer in Zhuanghe, China, so as to provide the basis for health decision on expanding the program of early detection and treatment. The expense of an early detection and treatment program for gastric cancer in patients found by screening, and also costs of traditional treatment in a hospital of Zhuanghe were assessed. Three major techniques of medical economics, namely cost-effective analysis (CEA), cost-benefit analysis (CBA) and cost-utility analysis (CUA), were used to assess the screening program. RESULTS from CEA showed that investing every 25, 235 Yuan on screening program in Zhuanghe area, one gastric cancer patient could be saved. Data from CUA showed that it was cost 1, 370 Yuan per QALY saved. RESULTS from CBA showed that: the total cost was 1,945,206 Yuan with a benefit as 8,669,709 Yuan and an CBR of 4.46. The early detection and treatment program of gastric cancer appears economic and society-beneficial. We suggest that it should be carry out in more high risk areas for gastric cancer.

The effectiveness of breast cancer screening programs in reducing mortality is well established in the scientific literature. The National Breast Cancer Screening Program in Israel provides biennial mammograms for women of average risk aged 50-74 and annual mammograms for women aged 40-49 at higher risk. Compliance is high, but differential. This study explores different factors associated with breast cancer screening attendance among women aged 40-74 years. Two main outcomes were studied: ever been screened and been screened in the 2 years preceding the study, using the cross-sectional Knowledge, Attitudes and Practices (KAP) Survey conducted in 2010-2012 among 2575 Israeli women aged 21+ years. The independent variables were sociodemographic characteristics, perceived health status, lifestyle habits, and healthcare fund membership. Bivariate and multivariable logistic regressions were conducted. Of the 943 participants aged 50-74, 87% had ever been screened and 74.8% had attended screening for breast cancer in the last 2 years. In multivariable models, Jewish compared to Arab women (adjusted prevalence ratio [APR] = 2.09, 95% confidence interval [CI]: 1.02-4.32), and unmarried compared to married women (APR = 2.9, 95% CI: 1.2-7.2), were more likely to have ever been screened. The only factor associated with breast cancer screening in the 2 years preceding the study was healthcare fund membership. In women aged 40-49 years, ethnicity was the only contributing factor associated with breast cancer screening, with higher screening rates in the 2 years preceding the study in Jewish versus Arab women (APR = 3.7, 95% CI: 1.52-9.3). Breast cancer screening attendance in Israel is high. However, significant differences are observed by membership of healthcare fund and by ethnicity, calling for better targeted outreach programs at this level.

There is limited information relating to routine depression screening and psychosocial assessment programs in private maternity settings in Australia. To describe the psychosocial profile of a sample of private maternity patients who participated in a depression screening and psychosocial risk assessment program as part of routine antenatal care, and to explore women's experience of receiving this component of pregnancy care. We conducted a retrospective medical records audit of 455 consecutive women having a routine psychosocial assessment and referral. Assessment was undertaken using the Edinburgh Postnatal Depression Scale (EPDS) and the Antenatal Risk Questionnaire (ANRQ) for psychosocial risk; 101 women completed a feedback survey about their experience of receiving routine psychosocial care. Of the 87.7% of women who completed both EPDS and ANRQ, 4.3% scored 13 or more on the EPDS. On the ANRQ, 25.3% of women endorsed one risk factor, 11.6% two risk factors and 10.5% three or more risk factors. Elevated EPDS scores were associated with major stresses in the last 12 months, high trait anxiety and significant past mental health issue/s. Acceptability of depression screening and psychosocial risk assessment was high. This study highlights the need for, and acceptability of, depression and psychosocial assessment in the private maternity sector. These findings are particularly timely given the provision of new Medicare Benefits Scheme items for obstetricians to undertake psychosocial assessment (both antenatally and postnally) in line with recommended clinical best practice. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

PURPOSE Multiple cancer screening tests have been advocated for the general population; however, clinicians and patients are not always well-informed of screening burdens. We sought to determine the cumulative risk of a false-positive screening result and the resulting risk of a diagnostic procedure for an individual participating in a multimodal cancer screening program. METHODS Data were analyzed from the intervention arm of the ongoing Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial, a randomized controlled trial to determine the effects of prostate, lung, colorectal, and ovarian cancer screening on disease-specific mortality. The 68,436 participants, aged 55 to 74 years, were randomized to screening or usual care. Women received serial serum tests to detect cancer antigen 125 (CA-125), transvaginal sonograms, posteroanterior-view chest radiographs, and flexible sigmoidoscopies. Men received serial chest radiographs, flexible sigmoidoscopies, digital rectal examinations, and serum prostate-specific antigen tests. Fourteen screening examinations for each sex were possible during the 3-year screening period. RESULTS After 14 tests, the cumulative risk of having at least 1 false-positive screening test is 60.4% (95% CI, 59.8%–61.0%) for men, and 48.8% (95% CI, 48.1%–49.4%) for women. The cumulative risk after 14 tests of undergoing an invasive diagnostic procedure prompted by a false-positive test is 28.5% (CI, 27.8%–29.3%) for men and 22.1% (95% CI, 21.4%–22.7%) for women. CONCLUSIONS For an individual in a multimodal cancer screening trial, the risk of a false-positive finding is about 50% or greater by the 14th test. Physicians should educate patients about the likelihood of false positives and resulting diagnostic interventions when counseling about cancer screening. PMID:19433838

In genomics, the return of negative screening results for rare, medically actionable conditions in large unselected populations with low prior risk of disease is novel and may involve important and nuanced concerns for communicating their meaning. Recruitment may result in self-selection because of participants' personal or family history, changing the characteristics of the screened population and interpretation of both positive and negative findings; prior motivations may also affect responses to results. Using data from GeneScreen, an exploratory adult screening project that targets 17 genes related to 11 medically actionable conditions, we address four questions: (1) Do participants self-select based on actual or perceived risk for one of the conditions? (2) Do participants understand negative results? (3) What are their psychosocial responses? (4) Are negative results related to changes in reported health-related behaviors? We found disproportionate enrollment of individuals at elevated prior risk for conditions being screened, and a need to improve communication about the nature of screening and meaning of negative screening results. Participants expressed no decision regret and did not report intention to change health-related behaviors. This study illuminates critical challenges to overcome if genomic screening is to benefit the general population.

Mass screening with abdominal ultrasonography (AUS) has been suggested as a tool to control adult hepatocellular carcinoma (HCC) in individuals, but its efficacy in reducing HCC mortality has never been demonstrated. This study aimed to assess the effectiveness of reducing HCC mortality by mass AUS screening for HCC based on a program designed and implemented in the Changhua Community-based Integrated Screening (CHCIS) program with an efficient invitation scheme guided by the risk score. We invited 11,114 (27.0%) of 41,219 eligible Taiwanese subjects between 45 and 69 years of age who resided in an HCC high-incidence area to attend a risk score-guided mass AUS screening between 2008 and 2010. The efficacy of reducing HCC mortality was estimated. Of the 8,962 AUS screening attendees (with an 80.6% attendance rate), a total of 16 confirmed HCC cases were identified through community-based ultrasonography screening. Among the 16 screen-detected HCC cases, only two died from HCC, indicating a favorable survival. The cumulative mortality due to HCC (per 100,000) was considerably lower in the invited AUS group (17.26) compared with the uninvited AUS group (42.87) and the historical control group (47.51), yielding age- and gender-adjusted relative mortality rates of 0.69 (95% confidence interval [CI]: 0.56-0.84) and 0.63 (95% CI: 0.52-0.77), respectively. Conclusion: The residents invited to community-based AUS screening for HCC, compared with those who were not invited, showed a reduction in HCC mortality by ∼31% among subjects aged 45-69 years who had not been included in the nationwide vaccination program against hepatitis B virus infection.

Purpose To analyze the cost and detection rate of a screening program for detecting glaucoma with imaging devices. Materials and methods In this cross-sectional study, a glaucoma screening program was applied in a population-based sample randomly selected from a population of 23,527. Screening targeted the population at risk of glaucoma. Examinations included optic disk tomography (Heidelberg retina tomograph [HRT]), nerve fiber analysis, and tonometry. Subjects who met at least 2 of 3 endpoints (HRT outside normal limits, nerve fiber index ≥30, or tonometry ≥21 mmHg) were referred for glaucoma consultation. The currently established (“conventional”) detection method was evaluated by recording data from primary care and ophthalmic consultations in the same population. The direct costs of screening and conventional detection were calculated by adding the unit costs generated during the diagnostic process. The detection rate of new glaucoma cases was assessed. Results The screening program evaluated 414 subjects; 32 cases were referred for glaucoma consultation, 7 had glaucoma, and 10 had probable glaucoma. The current detection method assessed 677 glaucoma suspects in the population, of whom 29 were diagnosed with glaucoma or probable glaucoma. Glaucoma screening and the conventional detection method had detection rates of 4.1% and 3.1%, respectively, and the cost per case detected was 1,410 and 1,435€, respectively. The cost of screening 1 million inhabitants would be 5.1 million euros and would allow the detection of 4,715 new cases. Conclusion The proposed screening method directed at population at risk allows a detection rate of 4.1% and a cost of 1,410 per case detected. PMID:28243057

2013-10-01

Employer wellness programs have grown rapidly in recent years with the interest in making an impact on employees' health. Successful programs are delivered through comprehensive solutions that are linked to an organization's business strategy and championed by senior leadership. Successful employee health management programs vary in the services, yet typically include the core components of health risk identification tools, behavior modification programs, educational programs, as well as changes to the workplace environment and culture. This article focuses on biometric screenings and was intended to provide employers and other stakeholders with information and guidance to help implement a successful screening program as part of an overall employee health management approach. The article is organized into four sections: goals and key success factors; methods and oversight; operations and delivery; and engagement and evaluation.

Given shared risk and maintaining factors between eating disorders and obesity, it may be important to include both eating disorder intervention and healthy weight management within a universal eating disorder care delivery program. This study evaluated differential eating disorder screening responses by initial weight status among university students, to assess eating disorder risk and pathology among individuals with overweight/obesity versus normal weight or underweight. 1529 individuals were screened and analyzed. Screening was conducted via pilot implementation of the Internet-based Healthy Body Image program on two university campuses. Fifteen percent of the sample had overweight/obesity. Over half (58%) of individuals with overweight/obesity screened as high risk for an eating disorder or warranting clinical referral, and 58% of individuals with overweight/obesity endorsed a ≥10-pound weight change over the past year. Compared to individuals with normal weight or underweight, individuals with overweight/obesity were more likely to identify as Black, endorse objective binge eating and fasting, endorse that eating disorder-related concerns impaired their relationships/social life and made them feel badly, and endorse higher weight/shape concerns. Results suggest rates of eating disorder pathology and clinical impairment are highest among students with overweight/obesity, and targeted intervention across weight categories and diverse races/ethnicities is warranted within universal eating disorder intervention efforts. Integrating eating disorder intervention and healthy weight management into universal prevention programs could reduce the incidence and prevalence of eating disorders, unhealthy weight control practices, and obesity among university students.

Prospective research studies often advance clinical practice in the emergency department (ED), but they can be costly and difficult to perform. In this report, we describe the implementation of a volunteer university student research assistant program that provides students exposure to medicine and clinical research while simultaneously increasing the capacity of an ED's research program. This type of program provides 15 hours per day of research assistant coverage for patient screening and enrolment for minimal risk research studies, and screening for higher risk studies. The latter is true without the added burden or costs of co-administering university course credit or pay for service, which are common features of most of these types of programs currently in operation. We have shown that our volunteer-based program is effective for an ED's research success as well as for its student participants. For other EDs interested in adopting similar programs, we provide the details on how to get such a program started and highlight the structure and non-monetary incentives that facilitate a program's ongoing success.

What is overdiagnosis and why should we take it seriously in cancer screening?

PubMed

Carter, Stacy M; Barratt, Alexandra

2017-07-26

Overdiagnosis occurs in a population when conditions are diagnosed correctly but the diagnosis produces an unfavourable balance between benefits and harms. In cancer screening, overdiagnosed cancers are those that did not need to be found because they would not have produced symptoms or led to premature death. These overdiagnosed cancers can be distinguished from false positives, which occur when an initial screening test suggests that a person is at high risk but follow-up testing shows them to be at normal risk. The cancers most likely to be overdiagnosed through screening are those of the prostate, thyroid, breast and lung. Overdiagnosis in cancer screening arises largely from the paradoxical problem that screening is most likely to find the slow-growing or dormant cancers that are least likely to harm us, and less likely to find the aggressive, fast-growing cancers that cause cancer mortality. This central paradox has become clearer over recent decades. The more overdiagnosis is produced by a screening program, the less likely the program is to serve its ultimate goal of reducing illness and premature death from cancer. Thus, it is vital that health professionals and researchers continue an open, scientific inquiry into the extent and consequences of overdiagnosis, and devise appropriate responses to it.

The spread of acquired immune deficiency syndrome (AIDS) demands a comprehensive and effective public health response. Because no treatment or vaccine is currently available, traditional infection control measures are being considered. Proposals include compulsory testing and screening of selected high risk populations. The fairness and accuracy of compulsory screening programs depend upon the reliability of medical technology and the balancing of public health and individual confidentiality interests. This Article proposes criteria for evaluating compulsory testing and screening programs. It concludes that voluntary identification, education, and counselling of infected persons is the most effective means of encouraging the behavioral changes that are necessary to halt the spread of AIDS.

This study aimed to evaluate the impact of seasonal variations in climate on the performance of the fecal immunochemical test (FIT) in screening for colorectal cancer in the National Cancer Screening Program in Korea. Data were extracted from the National Cancer Screening Program databases for participants who underwent FIT between 2009 and 2010. We compared positivity rates, cancer detection rates, interval cancer rates, positive predictive value, sensitivity, and specificity for FIT during the spring, summer, fall, and winter seasons in Korea. In total, 4,788,104 FIT results were analyzed. FIT positivity rate was lowest during the summer months. In the summer, the positive predictive value of FIT was about 1.1 times (adjusted odds ratio (aOR) 1.08, 95% confidence interval (CI) 1.00-1.16) higher in the overall FIT group and about 1.3 times (aOR 1.29, 95% CI 1.10-1.50) higher in the quantitative FIT group, compared to those in the other seasons. Cancer detection rates, however, were similar regardless of season. Interval cancer risk was significantly higher in the summer for both the overall FIT group (aOR 1.16, 95% CI 1.07-1.27) and the quantitative FIT group (aOR 1.31, 95% CI 1.12-1.52). In addition, interval cancers in the rectum and distal colon were more frequently detected in the summer and autumn than in the winter. The positivity rate of FIT was lower in the summer, and the performance of the FIT screening program was influenced by seasonal variations in Korea. These results suggest that more efforts to reduce interval cancer during the summer are needed in population-based screening programs using FIT, particularly in countries with high ambient temperatures.

Nutrition risk screening: the interrelationship of food insecurity, food intake, and unintentional weight change among homebound elders.

PubMed

Sharkey, Joseph R

2004-01-01

Nutrition risk screening is a key component of the homedelivered meals program. To examine direct and indirect relationships among individual components of nutrition risk, path analysis was conducted on routinely collected data from 908 homebound elders who received home-delivered meals. The good fit of the model revealed that specific nutrition risk factors and indicators of nutritional risk were directly and indirectly associated with meal frequency and unintended weight change. With the heightened vulnerability for poor nutritional health among homebound elders who report food insecurity, policymakers and service providers should strengthen efforts to target individual components of nutrition risk rather than aggregate scores or categorical measures.

The effectiveness of a CNS-led community-based COPD screening and intervention program.

PubMed

DeJong, Sandra R; Veltman, Rebecca H

2004-01-01

The purpose of this study was to evaluate the effectiveness of a screening program in identifying undiagnosed individuals with chronic obstructive pulmonary disease (COPD). THEORETICAL RATIONALE: Underdiagnosis of COPD is common. Symptoms do not usually become apparent until the disease is advanced. Consequently, by the time a diagnosis of COPD is made, based on symptoms, the individual has often lost up to 50% or more of their original lung capacity. Early diagnosis and intervention has been demonstrated to have an impact in slowing the progression of the disease. The study was based on the premise that when individuals become self-aware of their risk factors related to disease, they are more likely to change their behaviors. The Transtheoretical Model describes how individuals move through various stages of change and how they can be helped in transitioning from one stage to another. Subjects (n = 243) were recruited via letter, newspaper, and physician referral. The screening program consisted of (1) pulmonary function testing using a handheld spirometry device, (2) education about the test results and COPD, and (3) smoking cessation counseling. Current smokers and those found to have obstruction were contacted at 8 to 12 weeks after screening. Results indicated that 209 (86%) of participants were at risk for developing COPD as evidenced by current or past smoking status. Mild to moderate stage obstructive disease was found in 55 subjects (23%). Of 61 subjects contacted after the screening, 29 smokers (47%) indicated they had stopped smoking, were in the process of quitting, or were seriously considering quitting. Results support the use of a community-screening program to identify and help modify risk factors for COPD. IMPLICATIONS FOR NURSING PRACTICES: This project provides an example of how a clinical nurse specialist (CNS) can exercise all the spheres of CNS influence: the patient/client sphere, the nursing personnel sphere, and the organization sphere. In addition, the COPD screening project demonstrated how a CNS can successfully lead and direct a community initiative and influence others in changing behavior to enhance their state of health.

False-positives are a major concern in breast cancer screening. However, false-positives have been little evaluated as a prognostic factor for cancer detection. Our aim was to evaluate the association of false-positive results with the cancer detection risk in subsequent screening participations over a 17-year period. This is a retrospective cohort study of 762,506 women aged 45-69 years, with at least two screening participations, who underwent 2,594,146 screening mammograms from 1990 to 2006. Multilevel discrete-time hazard models were used to estimate the adjusted odds ratios (OR) of breast cancer detection in subsequent screening participations in women with false-positive results. False-positives involving a fine-needle aspiration cytology or a biopsy had a higher cancer detection risk than those involving additional imaging procedures alone (OR = 2.69; 95%CI: 2.28-3.16 and OR = 1.81; 95%CI: 1.70-1.94, respectively). The risk of cancer detection increased substantially if women with cytology or biopsy had a familial history of breast cancer (OR = 4.64; 95%CI: 3.23-6.66). Other factors associated with an increased cancer detection risk were age 65-69 years (OR = 1.84; 95%CI: 1.67-2.03), non-attendance at the previous screening invitation (OR = 1.26; 95%CI: 1.11-1.43), and having undergone a previous benign biopsy outside the screening program (OR = 1.24; 95%CI: 1.13-1.35). Women with a false-positive test have an increased risk of cancer detection in subsequent screening participations, especially those with a false-positive result involving cytology or biopsy. Understanding the factors behind this association could provide valuable information to increase the effectiveness of breast cancer screening. Copyright © 2012 Elsevier Ltd. All rights reserved.

Screening for skin cancer.

Malignant melanoma is often lethal, and its incidence in the United States has increased rapidly over the past 2 decades. Nonmelanoma skin cancer is seldom lethal, but, if advanced, can cause severe disfigurement and morbidity. Early detection and treatment of melanoma might reduce mortality, while early detection and treatment of nonmelanoma skin cancer might prevent major disfigurement and to a lesser extent prevent mortality. Current recommendations from professional societies regarding screening for skin cancer vary. To examine published data on the effectiveness of routine screening for skin cancer by a primary care provider, as part of an assessment for the U.S. Preventive Services Task Force. We searched the MEDLINE database for papers published between 1994 and June 1999, using search terms for screening, physical examination, morbidity, and skin neoplasms. For information on accuracy of screening tests, we used the search terms sensitivity and specificity. We identified the most important studies from before 1994 from the Guide to Clinical Preventive Services, second edition, and from high-quality reviews. We used reference lists and expert recommendations to locate additional articles. Two reviewers independently reviewed a subset of 500 abstracts. Once consistency was established, the remainder were reviewed by one reviewer. We included studies if they contained data on yield of screening, screening tests, risk factors, risk assessment, effectiveness of early detection, or cost effectiveness. We abstracted the following descriptive information from full-text published studies of screening and recorded it in an electronic database: type of screening study, study design, setting, population, patient recruitment, screening test description, examiner, advertising targeted at high-risk groups or not targeted, reported risk factors of participants, and procedure for referrals. We also abstracted the yield of screening data including probabilities and numbers of referrals, types of suspected skin cancers, biopsies, confirmed skin cancers, and stages and thickness of skin cancers. For studies that reported test performance, we recorded the definition of a suspicious lesion, the "gold-standard" determination of disease, and the number of true positive, false positive, true negative, and false negative test results. When possible, positive predictive values, likelihood ratios, sensitivity, and specificity were recorded. No randomized or case-control studies have been done that demonstrate that routine screening for melanoma by primary care providers reduces morbidity or mortality. Basal cell carcinoma and squamous cell carcinoma are very common, but detection and treatment in the absence of formal screening are almost always curative. No controlled studies have shown that formal screening programs will improve this already high cure rate. While the efficacy of screening has not been established, the screening procedures themselves are noninvasive, and the follow-up test, skin biopsy, has low morbidity. Five studies from mass screening programs reported the accuracy of skin examination as a screening test. One of these, a prospective study, tracked patients with negative results to determine the number of patients with false-negative results. In this study, the sensitivity of screening for skin cancer was 94% and specificity was 98%. Several recent case-control studies confirm earlier evidence that risk of melanoma rises with the presence of atypical moles and/or many common moles. One well-done prospective study demonstrated that risk assessment by limited physical exam identified a relatively small (<10%) group of primary care patients for more thorough evaluation. The quality of the evidence addressing the accuracy of routine screening by primary care providers for early detection of melanoma or nonmelanoma skin cancer ranged from poor to fair. We found no studies that assessed the effectiveness of periodic skin examination by a clinician in reducing melanoma mortality. Both self-assessment of risk factors or clinician examination can classify a small proportion of patients as at highest risk for melanoma. Skin cancer screening, perhaps using a risk-assessment technique to identify high-risk patients who are seeing a physician for other reasons, merits additional study as a strategy to address the excess burden of disease in older adults.

Issue addressed: Screening for cancer of the cervix, breast and bowel can reduce morbidity and mortality. Low participation rates in cancer screening have been identified among migrant communities internationally. Attempting to improve low rates of cancer screening, the Ethnic Communities Council of Queensland developed a pilot Cancer Screening Education Program for breast, bowel and cervical cancer. This study determines the impact of education sessions on knowledge, attitudes and intentions to participate in screening for culturally and linguistically diverse (CALD) communities living in Brisbane, Queensland. Methods: Seven CALD groups (Arabic-speaking, Bosnian, South Asian (including Indian and Bhutanese), Samoan and Pacific Island, Spanish-speaking, Sudanese and Vietnamese) participated in a culturally-tailored cancer screening education pilot program that was developed using the Health Belief Model. A pre- and post-education evaluation session measured changes in knowledge, attitudes and intention related to breast, bowel and cervical cancer and screening. The evaluation focussed on perceived susceptibility, perceived seriousness and the target population's beliefs about reducing risk by cancer screening. Results: There were 159 participants in the three cancer screening education sessions. Overall participants' knowledge increased, some attitudes toward participation in cancer screening became more positive and intent to participate in future screening increased (n=146). Conclusion: These results indicate the importance of developing screening approaches that address the barriers to participation among CALD communities and that a culturally-tailored education program is effective in improving knowledge, attitudes about and intentions to participate in cancer screening. So what?: It is important that culturally-tailored programs are developed in conjunction with communities to improve health outcomes.

Using lessons from breast, cervical, and colorectal cancer screening to inform the development of lung cancer screening programs.

Multiple advisory groups now recommend that high-risk smokers be screened for lung cancer by low-dose computed tomography. Given that the development of lung cancer screening programs will face many of the same issues that have challenged other cancer screening programs, the National Cancer Institute-funded Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium was used to identify lessons learned from the implementation of breast, cervical, and colorectal cancer screening that should inform the introduction of lung cancer screening. These lessons include the importance of developing systems for identifying and recruiting eligible individuals in primary care, ensuring that screening centers are qualified and performance is monitored, creating clear communication standards for reporting screening results to referring physicians and patients, ensuring follow-up is available for individuals with abnormal test results, avoiding overscreening, remembering primary prevention, and leveraging advances in cancer genetics and immunology. Overall, this experience emphasizes that effective cancer screening is a multistep activity that requires robust strategies to initiate, report, follow up, and track each step as well as a dynamic and ongoing oversight process to revise current screening practices as new evidence regarding screening is created, new screening technologies are developed, new biological markers are identified, and new approaches to health care delivery are disseminated.

Homeless children are known to be at risk for mental health and behavioral disorders due to housing instability and family and environmental risk factors, such as domestic violence. However, homeless children seldom receive screening for mental health and behavioral disorders with validated instruments. Moreover, few examples exist of programs that integrate outreach, screening, referral to appropriate diagnostic and therapeutic services, and care coordination. We describe early results of the Medical Home for Homeless Children Project, whose nurse care coordinators work with homeless families to conduct standardized nursing assessments that include evidence-based screening for child mental health and behavioral disorders with referral and case management for mental and behavioral health services. Screening identified a group of children with mental health issues that warranted referral, and many of those referrals were successfully completed.

Mammographic density and risk of breast cancer according to tumor characteristics and mode of detection: a Spanish population-based case-control study

PubMed Central

2013-01-01

Introduction It is not clear whether high mammographic density (MD) is equally associated with all subtypes of breast cancer (BC). We investigated the association between MD and subsequent BC, considering invasiveness, means of detection, pathologic subtype, and the time elapsed since mammographic exploration and BC diagnosis. Methods BC cases occurring in the population of women who attended screening from 1997 through 2004 in Navarre, a Spanish region with a fully consolidated screening program, were identified via record linkage with the Navarre Cancer Registry (n = 1,172). Information was extracted from the records of their first attendance at screening in that period. For each case, we randomly selected four controls, matched by screening round, year of birth, and place of residence. Cases were classified according to invasiveness (ductal carcinoma in situ (DCIS) versus invasive tumors), pathologic subtype (considering hormonal receptors and HER2), and type of diagnosis (screen-detected versus interval cases). MD was evaluated by a single, experienced radiologist by using a semiquantitative scale. Data on BC risk factors were obtained by the screening program in the corresponding round. The association between MD and tumor subtype was assessed by using conditional logistic regression. Results MD was clearly associated with subsequent BC. The odds ratio (OR) for the highest MD category (MD >75%) compared with the reference category (MD <10%) was similar for DCIS (OR = 3.47; 95% CI = 1.46 to 8.27) and invasive tumors (OR = 2.95; 95% CI = 2.01 to 4.35). The excess risk was particularly high for interval cases (OR = 7.72; 95% CI = 4.02 to 14.81) in comparison with screened detected tumors (OR = 2.17; 95% CI = 1.40 to 3.36). Sensitivity analyses excluding interval cases diagnosed in the first year after MD assessment or immediately after an early recall to screening yielded similar results. No differences were seen regarding pathologic subtypes. The excess risk associated with MD persisted for at least 7 to 8 years after mammographic exploration. Conclusions Our results confirm that MD is an important risk factor for all types of breast cancer. High breast density strongly increases the risk of developing an interval tumor, and this excess risk is not completely explained by a possible masking effect. PMID:23360535

Estimated Cost of Crashes in Commercial Drivers Supports Screening and Treatment of Obstructive Sleep Apnea

2009-01-01

Sleep apnea among commercial drivers may increase the risk of fall-asleep crashes, which incur large expenses. Drivers of passenger cars whose apnea is treated experience lower crash risk. Among community-based holders of commercial driver’s licenses, we considered three methods for identifying sleep apnea syndrome: 1) in-lab polysomnography; 2) selective in-lab polysomnography for high-risk drivers, where high risk is first identified by body mass index, age and gender, followed by oximetry in a subset of drivers; and 3) not screening. The costs for each of these three programs equaled the sum of the costs of testing, treatment of identified cases, and crashes. Assuming that treatment prevents apnea-related crashes, polysomnography is not cost-effective, because it was more expensive than the cost of crashes when no screening is done. Screening with BMI, age and gender, however, with confirmatory in-lab polysomnography only on high-risk drivers was cost-effective, as long as a high proportion (73.8%) of screened drivers accepts treatment. These findings indicate that strategies that reduce reliance on in-laboratory polysomnography may be more cost-effective than not screening, and that treatment acceptance may need to be a condition of employment for affected drivers.

Bacterial vaginosis (BV) is an important risk factor for preterm birth. BV is detected in 10-30% of pregnant women and is often asymptomatic. Treatment of BV during pregnancy seems to reduce the risk of preterm delivery among high-risk women. We performed a cost-effectiveness analysis of screening and treatment for BV in early pregnancy among asymptomatic women at low risk for preterm delivery. A decision tree was built with two arms. For the screening (and treatment) arm the probabilities were derived from our earlier randomized trial on screening and treatment for BV, consisting of BV-positive women treated with intravaginal clindamycin cream or placebo and also of BV-negative pregnant women. The probabilities of outcomes among these women were collected from antenatal clinic records and hospital records, and for the no-screening arm mainly from the Finnish Perinatal Statistics. The outcomes considered were preterm delivery, mode of delivery, peripartum infections and postpartum complications. The unit costs associated with these outcomes were mainly based on disease-related groups (DRGs). No-screening was compared with two screening programs (one with clindamycin, the other with metronidazole treatment) and subjected to sensitivity analyses. There was no significant difference between screening and no-screening strategies in the costs and in the rate of preterm deliveries but the screening strategy produced significantly fewer peripartum infections and postpartum complications. Sensitivity analyses suggested that the screening strategy may become cost-saving if the rate of preterm deliveries exceeds 3%. Screening and treatment for BV in early pregnancy may not reduce costs compared to no-screening in a population at low risk for preterm birth but would produce, at the same cost, more health benefits in terms of fewer peripartum infections and postpartum complications. However, it may be cost-saving if the rate of preterm deliveries is higher than 3%.

2016-01-01

Background Pancreatic cancer is the 4th leading cause of cancer death in the U.S. A screening protocol is needed to catch early stage, resectable disease. This study suggests a protocol for high-risk individuals and assesses the cost in the context of the Affordable Care Act. Methods Medicare and national average pricing were used for cost analysis of a protocol using MRI/MRCP biannually in high-risk groups. Results: ‘ Costs per year of life added’ based on Medicare and national average costs, respectively, are: $638.62 and $2542.37 for Peutz-Jehgers Syndrome, $945.33 and $3763.44 for Hereditary Pancreatitis, $1141.77 and $4545.45 for Familial Pancreatic Cancer and p16-Leiden mutations, and $356.42 and $1418.92 for new-onset diabetes over age 50 with weight loss or smoking. Conclusion A screening program using MRI/MRCP is affordable in high-risk populations. The U.S. Preventive Services Task Force must reevaluate its pancreatic cancer screening guidelines to make screening more cost-effective for the individual. PMID:26003200

Summary This study was carried out to investigate the prevalence and correlates of sexual risk behaviour among psychiatric inpatients in India. Consecutive inpatients (n = 618) were assessed using a structured interview and standardized measures. Women were more likely to be sexually active (50%) than men (36%), but equally likely (6% v. 5%) to engage in risky behaviour. Common risk behaviours included having a risky partner, having multiple partners, and exchanging money for sex. Being sexually active was associated with younger age, being married, being diagnosed with a disorder other than schizophrenia, and a history of drug use problems. Engaging in risky sexual behaviour was associated with being male, using tobacco products, and screening positive for either drug use or alcohol problems. Screening psychiatric patients for HIV risk behaviour can identify those who may benefit from risk reduction programs. PMID:12935383

Breast cancer is the first cancer among females in the Kingdom of Saudi Arabia, accounting for 27.4% of all newly diagnosed female cancers in 2010. There are several risk factors affecting the incidence of breast cancer where some factors influence the risk more than the others. We aimed to identify the different risk factors related to breast cancer among females participating in the breast-screening program in Riyadh, KSA. Based on data from phase-I of the breast-screening program, a case-control study was conducted on women living in Riyadh, KSA. A sample of 349 women (58 cases and 290 controls) was recruited to examine the different breast cancer correlates. Multivariate regression model was built to investigate the most important risk factors. The mean age of cases was 48.5±7.1 years. Age at marriage, number of pregnancy, age at menopause, oral contraceptive pills, breast feeding and family history of breast cancer in first-degree relative were identified as the most important correlates among the studied cohort. The findings of the current work suggested that age at marriage, age at menopause ⩾50 years and 1st degree family history of breast cancer were risk factors for breast cancer, while, age at menopause <50 years, number of pregnancies and practicing breast feeding were protective factors against breast cancer. There was no effect of body mass index or physical inactivity. Further studies are needed to explore the hereditary, familial and genetic background risk factors in Saudi population.

Human Papillomavirus Laboratory Testing: the Changing Paradigm

PubMed Central

2016-01-01

SUMMARY High-risk human papillomaviruses (HPVs) cause essentially all cervical cancers, most anal and oropharyngeal cancers, and some vaginal, vulvar, and penile cancers. Improved understanding of the pathogenesis of infection and the availability of newer tests are changing the approach to screening and diagnosis. Molecular tests to detect DNA from the most common high-risk HPVs are FDA approved for use in conjunction with cytology in cervical cancer screening programs. More-specific tests that detect RNA from high-risk HPV types are now also available. The use of molecular tests as the primary screening tests is being adopted in some areas. Genotyping to identify HPV16 and -18 has a recommended role in triaging patients for colposcopy who are high-risk HPV positive but have normal cytology. There are currently no recommended screening methods for anal, vulvar, vaginal, penile, or oropharyngeal HPV infections. HPV testing has limited utility in patients at high risk for anal cancer, but p16 immunohistochemistry is recommended to clarify lesions in tissue biopsy specimens that show moderate dysplasia or precancer mimics. HPV testing is recommended for oropharyngeal squamous cell tumors as a prognostic indicator. Ongoing research will help to improve the content of future guidelines for screening and diagnostic testing. PMID:26912568

Background: No previous studies had addressed the perceived risk of cervical cancer (CC) and its influence on screening practices and perceived barriers in Saudi Arabia. Methods: This cross-sectional study was conducted on 506 randomly selected Saudi female secondary school teachers in Al Hassa, Saudi Arabia to assess their level of knowledge about risk factors and signs of CC in relation to perceived risk and to characterize CC screening compliance using a self-administered questionnaire. Results: Of the included female Saudi teachers, 65.4% and 63.4% were considered less-knowledgeable about CC risk factors and early signs and symptoms respectively. Only 17.2% reported being previously examined for CC. The majority of participants perceived themselves to be at an average or below average risk of CC. Residing in urban areas was the strongest predictor of CC screening (Odds ratio ‘OR’= 3.39; 95% confidence intervals ‘CI= 1.76-6.46; P=0.001). Awareness of risk factors was significantly associated with higher awareness of signs of CC (OR 2.5; 95% CI=, P=0.001). Exploratory factor analysis showed that personal fears (of screening being embarrassing) was the major factor that hindered CC screening with a high loading eigenvalue of 4.392, explaining 30.8% of the barriers toward utilization, followed by health care related factors. Conclusion: Secondary school teachers in Al Hassa, Saudi Arabia showed low perceived risk, poor awareness about risk factors, signs and symptoms of CC and limited uptake of screening practices. This underlines the need for education programs on CC targeting this group. PMID:28545195

Cervical-cancer screening strategies that involve the use of conventional cytology and require multiple visits have been impractical in developing countries. We used computer-based models to assess the cost-effectiveness of a variety of cervical-cancer screening strategies in India, Kenya, Peru, South Africa, and Thailand. Primary data were combined with data from the literature to estimate age-specific incidence and mortality rates for cancer and the effectiveness of screening for and treatment of precancerous lesions. We assessed the direct medical, time, and program-related costs of strategies that differed according to screening test, targeted age and frequency, and number of clinic visits required. Single-visit strategies involved the assumption that screening and treatment could be provided in the same day. Outcomes included the lifetime risk of cancer, years of life saved, lifetime costs, and cost-effectiveness ratios (cost per year of life saved). The most cost-effective strategies were those that required the fewest visits, resulting in improved follow-up testing and treatment. Screening women once in their lifetime, at the age of 35 years, with a one-visit or two-visit screening strategy involving visual inspection of the cervix with acetic acid or DNA testing for human papillomavirus (HPV) in cervical cell samples, reduced the lifetime risk of cancer by approximately 25 to 36 percent, and cost less than 500 dollars per year of life saved. Relative cancer risk declined by an additional 40 percent with two screenings (at 35 and 40 years of age), resulting in a cost per year of life saved that was less than each country's per capita gross domestic product--a very cost-effective result, according to the Commission on Macroeconomics and Health. Cervical-cancer screening strategies incorporating visual inspection of the cervix with acetic acid or DNA testing for HPV in one or two clinical visits are cost-effective alternatives to conventional three-visit cytology-based screening programs in resource-poor settings.

Background Black men are at increased risk for prostate cancer (PCA), particularly with a family history (FH) of the disease. Previous reports have raised concern for suboptimal screening of Black men with a FH of PCA. We report on the extent of FH of PCA from a prospective, longitudinal PCA screening program for high-risk men. Methods Black men ages 35-69 are eligible for PCA screening through the Prostate Cancer Risk Assessment Program (PRAP) regardless of FH. Rates of self-reported FH of PCA, breast, and colon cancer at baseline were compared with an age-matched sample of Black men from the 2005 National Health Interview Survey (NHIS) using standard statistical methods. Results As of January 2007, 332 Black men with pedigree information were enrolled in PRAP and FH of PCA was compared to 838 Black men from the 2005 NHIS. Black men in PRAP reported significantly more first-degree relatives with PCA compared to Black men in the 2005 NHIS (34.3%, 95% CI 29.2-39.7 vs. 5.7%, 95% CI 3.9-7.4). Black men in PRAP also had more FH of breast cancer compared to the 2005 NHIS (11.5%, 95% CI 8.2-15.4 vs 6.3%, 95% CI 4.6-8.0). Conclusions FH of PCA appears to be a motivating factor for Black men seeking PCA screening. Targeted recruitment and education among Black families should improve PCA screening rates. Efforts to recruit Black men without a FH of PCA are also needed. Condensed Abstract Black men seeking prostate cancer screening have a substantial burden of family history of prostate cancer. Targeted education and enhancing discussion in Black families should increase prostate cancer screening and adherence. PMID:18816608

The objective was to determine if a free, voluntary diabetes screening program as a part of the blood donation process might be cost-effective. During the first 6 months of the program, 26,415 donors were screened using a single random plasma glucose (RPG) level. All donors were asked to eat before donation. Low-, moderate-, and high-risk groups were formed based on RPG levels (<140, 140-200, and >200 mg/dL). Contact with a telephone questionnaire was made with 139 of 178 (78%) of the persons in the high-risk group with 33 new cases of diabetes diagnosed by the donor's physician and 26 donors indicating that they were not diagnosed with diabetes. Sex- and age-matched donors in the low- and moderate-risk groups were contacted and administered the same questionnaire. The three risk groups were similar, except for body mass index (28.1 ± 5.4 kg/m2 vs. 29.9 ± 5.5 kg/m2 vs. 32.7 ± 5.6 kg/m2 , p < 0.001). The discriminative effectiveness of screening was evaluated by the area under the receiver operating characteristics (AROC) curve. The AROC curve was 0.950 (95% confidence interval, 0.920-0.979) for the identification of diabetes. Using a RPG cutoff of 200 mg/dL, sensitivity was 100%, specificity was 82%, and positive predictive value was 56%. Cost analyses showed that the mean cost to screen, per donor, was less than $1. Cost per case identified was estimated to be less than $500 for a RPG cutoff of 200 mg/dL. Screening during the blood donation process appears to be accurate, convenient, and inexpensive. © 2013 American Association of Blood Banks.

Adolescent suicidal behavior is a public health concern in South Africa. The purpose of this article is to report on the development of a screening tool for teachers to identify South African students who are most at risk for suicidal behavior. This need is addressed within the context of the limited number of mental health professionals available to provide screening and care services in South Africa. Grade 8 students participated by completing sociodemographic questionnaires and self-report psychometric instruments. A screening tool for suicidal behavior was developed using a 4-phase approach. Twelve factors for high-risk suicidal behavior were identified and included in the screening tool. While further research is needed to validate the screening tool, the findings provide a useful preliminary starting point for teachers to refer students at high risk for suicidal behavior to mental health services for treatment. This screening tool is based on factors that were identified as being associated with suicidal behavior from local research on South African adolescents. The tool contributes to research on adolescent mental health, particularly suicidal behavior, in developing low and middle income countries like South Africa, with the aim of creating African prevention and intervention programs.

Background Lung cancer screening may provide a “teachable moment” for promoting smoking cessation. This study assessed smoking cessation and relapse rates among individuals undergoing follow-up low-dose chest computed tomography (CT) in a clinical CT lung screening program and assessed the influence of initial screening results on smoking behavior. Methods Self-reported smoking status for individuals enrolled in a clinical CT lung screening program undergoing a follow-up CT lung screening exam between 1st February, 2014 and 31st March, 2015 was retrospectively reviewed and compared to self-reported smoking status using a standardized questionnaire at program entry. Point prevalence smoking cessation and relapse rates were calculated across the entire population and compared with exam results. All individuals undergoing screening fulfilled the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology: Lung Cancer Screening v1.2012® high-risk criteria and had an order for CT lung screening. Results A total of 1,483 individuals underwent a follow-up CT lung screening exam during the study interval. Smoking status at time of follow-up exam was available for 1,461/1,483 (98.5%). A total of 46% (678/1,461) were active smokers at program entry. The overall point prevalence smoking cessation and relapse rates were 20.8% and 9.3%, respectively. Prior positive screening exam results were not predictive of smoking cessation (OR 1.092; 95% CI, 0.715–1.693) but were predictive of reduced relapse among former smokers who had stopped smoking for 2 years or less (OR 0.330; 95% CI, 0.143–0.710). Duration of program enrollment was predictive of smoking cessation (OR 0.647; 95% CI, 0.477–0.877). Conclusions Smoking cessation and relapse rates in a clinical CT lung screening program rates are more favorable than those observed in the general population. Duration of participation in the screening program correlated with increased smoking cessation rates. A positive exam result correlated with reduced relapse rates among smokers recently quit smoking.

There is a lack of Canadian data concerning the effectiveness of diabetes interventions in the workplace. The objective of this study was to evaluate the effectiveness of Motivaction, a diabetes screening and education pilot program, in the workplace. The Motivaction program involves a voluntary web-based diabetes health-risk assessment, the Canadian Diabetes Risk Questionnaire (CANRISK), combined with an opportunity for those eligible (i.e. having diabetes or having a CANRISK score ≥21) to attend 2 on-site biometric screening meetings with a registered nurse and 4 educational sessions by telephone with a certified diabetes educator. Biometric data, as well as information about self-efficacy, lifestyle changes, productivity, well-being, mental health and program satisfaction, were collected at baseline and at 6 months. Attendance at the initial and 6-month clinical visits included 293 people. At baseline, 21% were identified as having prediabetes (13%) or having diabetes (8%). Statistically significant reductions in glycated hemoglobin levels from baseline to the study's end were observed in those with prediabetes or diabetes. No statistically significant changes in glycated hemoglobin levels were observed in individuals with normal levels or in those at risk for diabetes at baseline. No statistical differences were observed in terms of productivity or mental health for the full population or across diabetes-risk categories. More than 90% of employees would recommend the Motivaction program to other employers. This study provides a framework for future diabetes interventions in the workplace and demonstrates that workplace interventions may reduce employees' diabetes risk levels and are valued by employees.

In the last 35 yr, 17 commercial aviation accidents and incidents, with 576 fatalities, could likely have been attributed to mental disease of a pilot. Screening tools for mental health risks in airline pilots are needed. There is growing interest in pilot peer-support programs and how to incorporate them in a just culture, meaning that pilots can report mental health complaints without a risk of job or income loss. We combined findings from aviation accidents and incidents with a search of scientific literature to provide data-based recommendations for screening, peer-support, and a just culture approach to mental health problems. Commercial aviation accidents and incidents in which a mental disorder of a pilot was thought to play a role were reviewed. Subsequently, PubMed and PsychInfo literature searches were performed on peer-support programs, just culture human resource management, and the risk of negative life events on developing suicidal ideation and behavior in comparable professional groups. Lethal accidents were mostly related to impaired coping with negative life events. Negative life events are clearly related to suicidal thoughts, attempts, and completed suicide. A protective effect of peer-support programs on mental health problems has not been established, although peer-support programs are generally appreciated by those involved. We did not find relevant literature on just culture. Negative life events are likely a useful screening tool for mental health risks. There is still a lack of evidence on how peer-support groups should be designed and how management of mental health risks can be implemented in a just culture.Mulder S, de Rooy D.

This study aimed to: (1) Estimate cumulative risk of recall from breast screening where no cancer is detected (a harm) in Australia; (2) Compare women screened annually versus biennially, commencing age 40 versus 50; and (3) Compare with international findings. At the no-cost metropolitan program studied, women attended biennial screening, but were offered annual screening if regarded at elevated risk for breast cancer. The cumulative risk of at least one recall was estimated using discrete-time survival analysis. Cancer detection statistics were computed. In total, 801,636 mammograms were undertaken in 231,824 women. Over 10 years, cumulative risk of recall was 13.3 % (95 % CI 12.7-13.8) for those screened biennially, and 19.9 % (CI 16.6-23.2) for those screened annually from age 50-51. Cumulative risk of complex false positive involving a biopsy was 3.1 % (CI 2.9-3.4) and 5.0 % (CI 3.4-6.6), respectively. From age 40-41, the risk of recall was 15.1 % (CI 14.3-16.0) and 22.5 % (CI 17.9-27.1) for biennial and annual screening, respectively. Corresponding rates of complex false positive were 3.3 % (CI 2.9-3.8) and 6.3 % (CI 3.4-9.1). Over 10 mammograms, invasive cancer was detected in 3.4 % (CI 3.3-3.5) and ductal carcinoma in situ in 0.7 % (CI 0.6-0.7) of women, with a non-significant trend toward a larger proportion of Tis and T1N0 cancers in women screened annually (74.5 %) versus biennially (70.1 %), χ (2) = 2.77, p = 0.10. Cancer detection was comparable to international findings. Recall risk was equal to European estimates for women screening from 50 and lower for screening from 40. Recall risk was half of United States' rates across start age and rescreening interval categories. Future benefit/harm balance sheets may be useful for communicating these findings to women.

To explore the accessibility of standardized printed information materials of the national Dutch colorectal cancer screening program among low health literate screening invitees and to assess the effect of the information on their knowledge about colorectal cancer and the screening program. Linguistic tools were used to analyze the text and design characteristics. The accessibility, comprehensibility and relevance of the information materials were explored in interviews and in observations (n=25). The effect of the information on knowledge was assessed in an online survey (n=127). The materials employed a simple text and design. However, respondents expressed problems with the amount of information, and the difference between screening and diagnostic follow-up. Knowledge significantly increased in 10 out of 16 items after reading the information but remained low for colorectal cancer risk, sensitivity of testing, and the voluntariness of colorectal cancer screening. Despite intelligible linguistic and design characteristics, screening invitees with low health literacy had problems in accessing, comprehending and applying standard information materials on colorectal cancer screening, and lacked essential knowledge for informed decision-making about participation. To enable equal access to informed decision-making, information strategies need to be adjusted to the skills of low health literate screening invitees. Copyright © 2016 Elsevier Ireland Ltd.

The Centers for Disease Control and Prevention recommend that local public health agencies use local data to identify children at risk for lead exposure to ensure that they receive preventive services. The objective of this study was to demonstrate the usefulness of a geographic information system (GIS) in identifying children at risk for lead exposure. We conducted a descriptive study, using GIS technology, of the blood lead (BPb) levels and residential location of at-risk children screened for lead exposure. "At-risk children" were defined as those children living in housing built before 1950 or in an area with a high proportion of older housing. The study was conducted in Jefferson County, Kentucky, USA. Participants were the cohort of children born in 1995 and screened from 1996 through 1997, and children younger than age 7 years who were screened from 1994 through 1998. Outcome measures were the BPb level and residential location (address or target zone) of at-risk children screened from 1996 through 1997, and the number and location of homes where more than one child had been poisoned by lead from 1994 through 1998. The proportion of children screened who live within zones targeted for universal screening varied from 48% to 53%, while only 50% of the at-risk children in the entire county were screened. Between 1994 and 1998, 79 homes housed 35% of the 524 children with lead poisoning. These housing units were prioritized for lead-hazard remediation. Significant numbers of at-risk children throughout the county were not being tested for lead exposure, even in prioritized areas. GIS can be very useful to health departments in planning lead exposure screening strategies and measuring program performance. PMID:11171530

To explore the long-term impact of a universal screening intervention for depression on suicide rates among older community-dwelling adults, with gender as an effect modifier. Controlled cohort study reporting long-term follow-up of previous research. Two sets of three municipalities in Japan were assigned as intervention and control regions and compared with the surrounding zone and prefecture. Intervention area residents aged 60 years and older (14,291) were invited to participate in a 2-year intervention (2005-2006). Four population-based dynamic cohorts of residents aged 65 years and older (1999-2010) were included as subjects, 6 years before and after the intervention started. At-risk residents within the intervention region (4,918) were invited for a two-step screening program; 2,552 participated in the program linked with care/support services for 2 years. An education program open to the public was held. Changes in suicide from a 6-year baseline to the 2-year intervention and a 4-year follow-up in the intervention region (11,700 adults ≥65 years) were compared with a matched control and two comparison areas using mixed-effects negative binomial regression models. Suicide rates among older adults exposed to screening were compared with those of the control region. Suicide rates in the intervention region decreased by 48%, which was significantly greater than in the three comparison areas. The program's benefits lasted longer for women than men. Screening exposure may be associated with decreased suicide risk over the 4-year follow-up. Universal screening may decrease suicide rates among older adults, with potential gender differences in treatment response. Copyright © 2016 American Association for Geriatric Psychiatry.

Abstract Background: Emergency department (ED) human immunodeficiency virus (HIV) screening programs are challenged by the unsustainable cost of exogenous staff and the relatively low penetration rates. Kiosk systems have increased registration efficiency in various clinical settings and have shown promising results for advancing various public health initiatives. This study evaluated the usability of kiosks within the existing HIV testing program and assessed patients' perceived acceptability of kiosk-based screening in the ED. Subjects and Methods: ED patients (n=88) were asked to complete both a Registration Module (intended to integrate into the ED's pending kiosk registration system) and a Risk Assessment Module using a pen-based touchscreen tablet platform. Participants provided feedback upon program completion. All comments, questions, and errors were documented. Kiosk programs tracked time spent on each screen. Quantitative (chi-squared test or t test) and qualitative data analyses were performed. Results: Consented subjects (n=62) were 60% female, 69% were black, the mean±standard deviation age was 37.8±11.4 years, 52% had a high school degree or less, and 50% reported no prior kiosk experience. Mean time spent on the Registration and Risk Assessment Modules was 2:35±1:24 min and 5:09±1:58 min, respectively. The leading technical challenge identified was login: 84% of patients required assistance. Removal of the login screen reduced times to 1:05±0:36 min and 4:10±1:38 min. Ninety-five percent of subjects reported length of use as “just right,” and over 75% of patients found the software easy to use, answered questions without help, and preferred screening on the kiosk to in-person interviews. Favorite aspects of the program included ease of use (52%), privacy (48%), and speed (30%). Sixty-six percent of patients reported there was nothing they disliked or would change. Conclusions: ED patient response to the kiosk system was favorable. Subjects easily and quickly navigated the program, with the exception of a login screen, which could be eliminated via automated login using ID bracelet scanners. PMID:24205808

Favorite aspects of the program included ease of use (52%), privacy (48%), and speed (30%). Sixty-six percent of patients reported there was nothing they disliked or would change. ED patient response to the kiosk system was favorable. Subjects easily and quickly navigated the program, with the exception of a login screen, which could be eliminated via automated login using ID bracelet scanners.

The DuPage Patient Navigation Collaborative evaluated the Patient Navigation Research Program (PNRP) model for uninsured women receiving free breast or cervical cancer screening through the Illinois Breast and Cervical Cancer Program in DuPage County, Illinois. We used medical records review and patient surveys of 477 women to compare median follow-up times with external Illinois Breast and Cervical Cancer Program and Chicago PNRP benchmarks of performance. We examined the extent to which we mitigated community-defined timeliness risk factors for delayed follow-up, with a focus on Spanish-speaking participants. Median follow-up time (29.0 days for breast and 56.5 days for cervical screening abnormalities) compared favorably to external benchmarks. Spanish-speaking patients had lower health literacy, lower patient activation, and more health care system distrust than did English-speaking patients, but despite the prevalence of timeliness risk factors, we observed no differences in likelihood of delayed (> 60 days) follow-up by language. Our successful replication and scaling of the PNRP navigation model to DuPage County illustrates a promising approach for future navigator research.

Lung cancer is the leading cause of cancer-related death in China. The results from a randomized controlled trial using annual low-dose computed tomography (LDCT) in specific high-risk groups demonstrated a 20% reduction in lung cancer mortality. The aim of tihs study is to establish the China National lung cancer screening guidelines for clinical practice. The China lung cancer early detection and treatment expert group (CLCEDTEG) established the China National Lung Cancer Screening Guideline with multidisciplinary representation including 4 thoracic surgeons, 4 thoracic radiologists, 2 medical oncologists, 2 pulmonologists, 2 pathologist, and 2 epidemiologist. Members have engaged in interdisciplinary collaborations regarding lung cancer screening and clinical care of patients with at risk for lung cancer. The expert group reviewed the literature, including screening trials in the United States and Europe and China, and discussed local best clinical practices in the China. A consensus-based guidelines, China National Lung Cancer Screening Guideline (CNLCSG), was recommended by CLCEDTEG appointed by the National Health and Family Planning Commission, based on results of the National Lung Screening Trial, systematic review of evidence related to LDCT screening, and protocol of lung cancer screening program conducted in rural China. Annual lung cancer screening with LDCT is recommended for high risk individuals aged 50-74 years who have at least a 20 pack-year smoking history and who currently smoke or have quit within the past five years. Individualized decision making should be conducted before LDCT screening. LDCT screening also represents an opportunity to educate patients as to the health risks of smoking; thus, education should be integrated into the screening process in order to assist smoking cessation. A lung cancer screening guideline is recommended for the high-risk population in China. Additional research , including LDCT combined with biomarkers, is needed to optimize the approach to low-dose CT screening in the future.

To compare breast cancer cumulative incidence, time evolution and stage at diagnosis between participants and non-participant women in a population-based screening program. Cohort study of breast cancer incidence in relation to participation in a population screening program. The study population included women from the target population of the screening program. The source of information for diagnostics and stages was the population-based cancer registry. The analysis period was 1999-2010. The Relative Risk for invasive, in situ, and total cancers diagnosed in participant women compared with non-participants were respectively 1.16 (0.94-1.43), 2.98 (1.16-7.62) and 1.22 (0.99-1.49). The Relative Risk for participants versus non-participants was 2.47 (1.55-3.96) for diagnosis at stagei, 2.58 (1.67-3.99) for T1 and 2.11 (1.38-3.23) for negative lymph node involvement. The cumulative incidence trend had two joint points in both arms, with an Annual Percent of Change of 92.3 (81.6-103.5) between 1999-2001, 18.2 (16.1-20.3) between 2001-2005 and 5.9 (4.0-7.8) for the last period in participants arm, and 72.6 (58.5-87.9) between 1999-2001, 12.6 (7.9-17.4) between 2001-2005, and 8.6 (6.5-10.6) in the last period in the non-participant arm. Participating in the breast cancer screening program analyzed increased the in situ cumulative cancer incidence, but not the invasive and total incidence. Diagnoses were earlier in the participant arm. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Effectiveness of traveller screening for emerging pathogens is shaped by epidemiology and natural history of infection

During outbreaks of high-consequence pathogens, airport screening programs have been deployed to curtail geographic spread of infection. The effectiveness of screening depends on several factors, including pathogen natural history and epidemiology, human behavior, and characteristics of the source epidemic. We developed a mathematical model to understand how these factors combine to influence screening outcomes. We analyzed screening programs for six emerging pathogens in the early and late stages of an epidemic. We show that the effectiveness of different screening tools depends strongly on pathogen natural history and epidemiological features, as well as human factors in implementation and compliance. For pathogens with longer incubation periods, exposure risk detection dominates in growing epidemics, while fever becomes a better target in stable or declining epidemics. For pathogens with short incubation, fever screening drives detection in any epidemic stage. However, even in the most optimistic scenario arrival screening will miss the majority of cases.

Background Screening for serum cryptococcal antigen (CrAg) may identify those at risk for disseminated cryptococcal disease (DCD), and pre-emptive fluconazole treatment may prevent progression to DCD. In August 2012, the Western Cape Province (WC), South Africa, adopted provider-initiated CrAg screening. We evaluated the implementation and effectiveness of this large-scale public-sector program during its first year, September 1, 2012—August 31, 2013. Methods We used data from the South African National Health Laboratory Service, WC provincial HIV program, and nationwide surveillance data for DCD. We assessed the proportion of eligible patients screened for CrAg (CrAg test done within 30 days of CD4 date) and the prevalence of CrAg positivity. Incidence of DCD among those screened was compared with those not screened. Results Of 4,395 eligible patients, 26.6% (n=1170) were screened. The proportion of patients screened increased from 15.9% in September 2012 to 36.6% in August 2013. The prevalence of positive serum CrAg was 2.1%. Treatment data were available for 13 of 24 CrAg-positive patients; nine of 13 were treated with fluconazole. Nine (0.8%) incident cases of DCD occurred among the 1170 patients who were screened for CrAg vs. 49 (1.5%) incident cases among the 3225 patients not screened (p=0.07). Conclusions Relatively few eligible patients were screened under the WC provider-initiated CrAg screening program. Unscreened patients were nearly twice as likely to develop DCD. CrAg screening can reduce the burden of DCD, but needs to be implemented well. To improve screening rates, countries should consider laboratory-based reflexive screening when possible. PMID:26926942

Currently, breast cancer is the most prevalent tumor among Mexican women. Screening methods such as mammography could potentially reduce the health and economic burden of breast cancer; however, its risk-benefit balance is still unclear. To estimate the cost-effectiveness of different breast cancer screening programs using mammography in Mexico and to contribute to the decision-making process on this preventive measure. A simulation study was performed using population data and incidence rates. Several screening programs were assessed using the cost-effectiveness methodology recommended by the World Health Organization. The feasible recommended screening program has an examination schedule periodicity of every three years, with a population coverage of 0, 15, 18, 20, 25, 20, 18, and 0% for the age groups of 25-40, 40-45, 45-50, 50-55, 55-60, 60-65, 65-70, and 70-75 years, respectively. Given the present coverage in Mexico, it is necessary to optimize our resource allocation to improve the country's breast cancer prevention policy.

Since the Pap test was introduced in the 1940s, there has been an approximately 70% reduction in the incidence of squamous cell cervical cancers in many developed countries by the application of organized and opportunistic screening programs. The efficacy of the Pap test, however, is hampered by high interobserver variability and high false-negative and false-positive rates. The use of biomarkers has demonstrated the ability to overcome these issues, leading to improved positive predictive value of cervical screening results. In addition, the introduction of HPV primary screening programs will necessitate the use of a follow-up test with high specificity to triage the high number of HPV-positive tests. This paper will focus on protein biomarkers currently available for use in cervical cancer screening, which appear to improve the detection of women at greatest risk for developing cervical cancer, including Ki-67, p16INK4a, BD ProEx C, and Cytoactiv HPV L1.

Background Identification of risk factors for lower extremity (LE) injury in sport and military/first-responder occupations is required to inform injury prevention strategies. Objective To determine if poor movement quality is associated with LE injury in sport and military/first-responder occupations. Material and methods Five electronic databases were systematically searched. Studies selected included: original data; analytic design; movement quality outcome (qualitative rating of functional compensation, asymmetry, impairment or efficiency of movement control); LE injury sustained with sport or military/first-responder occupation. The PRISMA guidelines were followed. Two independent authors assessed the quality [Downs and Black (DB) criteria] and level of evidence (Oxford Centre of Evidence-Based Medicine model). Results Of 4361 potential studies, 17 were included. The majority were low quality cohort studies (level 4 evidence). Median DB score was 11/33 (range 3–15). Heterogeneity in methodology and injury definition precluded meta-analyses. The Functional Movement Screen was the most common outcome investigated (15/17 studies). Four studies considered interrelationships between risk factors, seven reported diagnostic accuracy and none tested an intervention program targeting individuals identified as high-risk. There is inconsistent evidence that poor movement quality is associated with increased risk of LE injury in sport and military/first-responder occupations. Conclusions Future research should focus on high quality cohort studies to identify the most relevant movement quality outcomes for predicting injury risk followed by developing and evaluating pre-participation screening and LE injury prevention programs through high quality randomized controlled trials targeting individuals at greater risk of injury based upon screening tests with validated test properties.

Lung cancer screening guidelines recommend using individualized risk models to refer ever-smokers for screening. However, different models select different screening populations. The performance of each model in selecting ever-smokers for screening is unknown. To compare the U.S. screening populations selected by 9 lung cancer risk models (the Bach model; the Spitz model; the Liverpool Lung Project [LLP] model; the LLP Incidence Risk Model [LLPi]; the Hoggart model; the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial Model 2012 [PLCOM2012]; the Pittsburgh Predictor; the Lung Cancer Risk Assessment Tool [LCRAT]; and the Lung Cancer Death Risk Assessment Tool [LCDRAT]) and to examine their predictive performance in 2 cohorts. Population-based prospective studies. United States. Models selected U.S. screening populations by using data from the National Health Interview Survey from 2010 to 2012. Model performance was evaluated using data from 337 388 ever-smokers in the National Institutes of Health-AARP Diet and Health Study and 72 338 ever-smokers in the CPS-II (Cancer Prevention Study II) Nutrition Survey cohort. Model calibration (ratio of model-predicted to observed cases [expected-observed ratio]) and discrimination (area under the curve [AUC]). At a 5-year risk threshold of 2.0%, the models chose U.S. screening populations ranging from 7.6 million to 26 million ever-smokers. These disagreements occurred because, in both validation cohorts, 4 models (the Bach model, PLCOM2012, LCRAT, and LCDRAT) were well-calibrated (expected-observed ratio range, 0.92 to 1.12) and had higher AUCs (range, 0.75 to 0.79) than 5 models that generally overestimated risk (expected-observed ratio range, 0.83 to 3.69) and had lower AUCs (range, 0.62 to 0.75). The 4 best-performing models also had the highest sensitivity at a fixed specificity (and vice versa) and similar discrimination at a fixed risk threshold. These models showed better agreement on size of the screening population (7.6 million to 10.9 million) and achieved consensus on 73% of persons chosen. No consensus on risk thresholds for screening. The 9 lung cancer risk models chose widely differing U.S. screening populations. However, 4 models (the Bach model, PLCOM2012, LCRAT, and LCDRAT) most accurately predicted risk and performed best in selecting ever-smokers for screening.

Noncommunicable disease (NCDs), psychological, substance use disorders, and stress-related issues have been less understood in Indian industrial settings. Systems for screening and early identification of the above have not been integrated in workplaces, nor there is a strong regulatory backing for the same. To explore the feasibility of integrating mental health and select NCD risk factor screening with the periodical medical examination of employees. To identify proportion of employees with select NCD risk factors and symptoms suggestive of mental health problems. Around 10% of employees from a leading motor industry in Bangalore, (706) participated in this cross-sectional voluntary screening program. This screening was conducted as a part of their annual medical examination. A mixed method of self-report and interview administered technique was adopted for the same. Descriptive statistical methods (proportions, median, mean, and standard deviation (SD)) and Chi-square test of significance. Screening revealed the following; tobacco use (18%), alcohol use (57%), perceived work stress (10%), and obesity (3%). Nearly 23% screened positive for psychological distress. Time consumed for this assessment was 1-5 min. Initial attempts point out that it is feasible to integrate screening for mental health, substance use, and NCD risk factors in periodic medical examination using a combination of self-report and interview-administered method, though further detailed assessments for confirmation is necessary.

BACKGROUND The Centers for Disease Control and Prevention initiated the Colorectal Cancer Screening Demonstration Program (CRCSDP) to explore the feasibility of establishing a large-scale colorectal cancer (CRC) screening program for underserved populations in the United States. The authors of this report assessed the clinical costs incurred at each of the 5 participating sites during the demonstration period. METHODS By using data on payments to providers by each of the 5 CRCSDP sites, the authors estimated costs for specific clinical services and overall clinical costs for each of the 2 CRC screening methods used by the sites: colonoscopy and fecal occult blood test (FOBT). RESULTS Among CRCSDP clients who were at average risk for CRC and for whom complete cost data were available, 2131 were screened by FOBT, and 1888 were screened by colonoscopy. The total average clinical cost per individual screened by FOBT (including costs for screening, diagnosis, initial surveillance, office visits, and associated clinical services averaged across all individuals who received screening FOBT) ranged from $48 in Nebraska to $149 in Greater Seattle. This compared with an average clinical cost per individual for all services related to the colonoscopy screening ranging from $654 in St. Louis to $1600 in Baltimore City. CONCLUSIONS Variations in how sites contracted with providers and in the services provided through CRCSDP affected the cost of clinical services and the complexity of collecting cost data. Health officials may find these data useful in program planning and budgeting. PMID:23868481

A patient-level Markov decision model was used to simulate a virtual cohort of 500,000 women 40 years old and over, in relation to osteoporosis-related hip, clinical vertebral, and wrist bone fractures events. Sixteen different screening options of three main scenario groups were compared: (1) the status quo (no specific national prevention program); (2) a universal primary prevention program; and (3) a universal screening and treatment program based on the 10-year absolute risk of fracture. The outcomes measured were total directs costs from the perspective of the public health care system, number of fractures, and quality-adjusted life-years (QALYs). Results show that an option consisting of a program promoting physical activity and treatment if a fracture occurs is the most cost-effective (CE) (cost/fracture averted) alternative and also the only cost saving one, especially for women 40 to 64 years old. In women who are 65 years and over, bone mineral density (BMD)-based screening and treatment based on the 10-year absolute fracture risk calculated using a Canadian Association of Radiologists and Osteoporosis Canada (CAROC) tool is the best next alternative. In terms of cost-utility (CU), results were similar. For women less than 65 years old, a program promoting physical activity emerged as cost-saving but BMD-based screening with pharmacological treatment also emerged as an interesting alternative. In conclusion, a program promoting physical activity is the most CE and CU option for women 40 to 64 years old. BMD screening and pharmacological treatment might be considered a reasonable alternative for women 65 years old and over because at a healthcare capacity of $50,000 Canadian dollars ($CAD) for each additional fracture averted or for one QALY gained its probabilities of cost-effectiveness compared to the program promoting physical activity are 63% and 75%, respectively, which could be considered socially acceptable. Consideration of the indirect costs could change these findings. PMID:22991210

Molecular tests potentially improving HPV screening and genotyping for cervical cancer prevention

Gradíssimo, Ana

2018-01-01

INTRODUCTION Human papillomavirus (HPV)-related cancers can be averted by type-specific vaccination (primary prevention) and/or through detection and ablation of precancerous cervical lesions (secondary prevention). This review presents current challenges to cervical cancer screening programs, focusing on recent molecular advances in HPV testing and potential improvements on risk stratification. AREAS COVERED High-risk (HR)-HPV DNA detection has been progressively incorporated into cervix cancer prevention programs based on its increased sensitivity. Advances in next-generation sequencing (NGS) are being rapidly applied to HPV typing. However, current HPV DNA tests lack specificity for identification of cervical precancer (CIN3). HPV typing methods were reviewed based on published literature, with a focus on these applications for screening and risk stratification in the emerging complex clinical scenario post-vaccine introduction. In addition, the potential for NGS technologies to increase specificity is discussed in regards to reflex testing of specimens for emerging biomarkers for cervix precancer/cancer. EXPERT COMMENTARY Integrative multi-disciplinary molecular tests accurately triaging exfoliated cervical specimens will improve cervical cancer prevention programs while simplifying healthcare procedures in HPV-infected women. Hence, the concept of a “liquid-biopsy” (i.e., “molecular” Pap test) highly specific for early identification of cervical precancerous lesions is of critical importance in the years to come.

Purpose The purpose of this study was to investigate the effects of breast density on breast cancer risk among women screened via a nationwide mammographic screening program. Patients and methods We conducted a nested case–control study for a randomly selected population of 1,561 breast cancer patients and 6,002 matched controls from the National Cancer Screening Program. Breast density was measured and recorded by two independent radiologists using the Breast Imaging Reporting and Data System (BI-RADS). Associations between BI-RADS density and breast cancer risk were evaluated according to screening results, time elapsed since receiving non-recall results, age, and menopausal status after adjusting for possible covariates. Results Breast cancer risk for women with extremely dense breasts was five times higher (adjusted odds ratio [aOR] =5.0; 95% confidence interval [CI]) =3.7–6.7) than that for women with an almost entirely fatty breast, although the risk differed between recalled women (aOR =3.3, 95% CI =2.3–3.6) and women with non-recalled results (aOR =12.1, 95% CI =6.3–23.3, P-heterogeneity =0.001). aORs for BI-RADS categories of breast density were similar when subjects who developed cancer after showing non-recall findings during initial screening were grouped according to time until cancer diagnosis thereafter (<1 and ≥1 year). The prevalence of dense breasts was higher in younger women, and the association between a denser breast and breast cancer was stronger in younger women (heterogeneously dense breast: aOR =7.0, 95% CI =2.4–20.3, women in their 40s) than older women (aOR =2.5, 95% CI =1.1–6.0, women in their 70s or more). In addition, while the positive association remained, irrespective of menopausal status, the effect of a dense breast on breast cancer risk was stronger in premenopausal women. Conclusion This study confirmed an increased risk of breast cancer with greater breast density in Korean women which was consistent regardless of BI-RADS assessment category, time interval after initially non-recall results, and menopausal status.

A Low-Cost Method for Multiple Disease Prediction.

PubMed

Bayati, Mohsen; Bhaskar, Sonia; Montanari, Andrea

Recently, in response to the rising costs of healthcare services, employers that are financially responsible for the healthcare costs of their workforce have been investing in health improvement programs for their employees. A main objective of these so called "wellness programs" is to reduce the incidence of chronic illnesses such as cardiovascular disease, cancer, diabetes, and obesity, with the goal of reducing future medical costs. The majority of these wellness programs include an annual screening to detect individuals with the highest risk of developing chronic disease. Once these individuals are identified, the company can invest in interventions to reduce the risk of those individuals. However, capturing many biomarkers per employee creates a costly screening procedure. We propose a statistical data-driven method to address this challenge by minimizing the number of biomarkers in the screening procedure while maximizing the predictive power over a broad spectrum of diseases. Our solution uses multi-task learning and group dimensionality reduction from machine learning and statistics. We provide empirical validation of the proposed solution using data from two different electronic medical records systems, with comparisons to a statistical benchmark.

Background: It is estimated that millions of North Americans would qualify for lung cancer screening and that billions of dollars of national health expenditures would be required to support population-based computed tomography lung cancer screening programs. The decision to implement such programs should be informed by data on resource utilization and costs. Methods: Resource utilization data were collected prospectively from 2059 participants in the Pan-Canadian Early Detection of Lung Cancer Study using low-dose computed tomography (LDCT). Participants who had 2% or greater lung cancer risk over 3 years using a risk prediction tool were recruited from seven major cities across Canada. A cost analysis was conducted from the Canadian public payer’s perspective for resources that were used for the screening and treatment of lung cancer in the initial years of the study. Results: The average per-person cost for screening individuals with LDCT was $453 (95% confidence interval [CI], $400–$505) for the initial 18-months of screening following a baseline scan. The screening costs were highly dependent on the detected lung nodule size, presence of cancer, screening intervention, and the screening center. The mean per-person cost of treating lung cancer with curative surgery was $33,344 (95% CI, $31,553–$34,935) over 2 years. This was lower than the cost of treating advanced-stage lung cancer with chemotherapy, radiotherapy, or supportive care alone, ($47,792; 95% CI, $43,254–$52,200; p = 0.061). Conclusion: In the Pan-Canadian study, the average cost to screen individuals with a high risk for developing lung cancer using LDCT and the average initial cost of curative intent treatment were lower than the average per-person cost of treating advanced stage lung cancer which infrequently results in a cure.

A national survey was conducted to assess immunization practices and tuberculosis screening methods for animal care and research workers in biomedical settings throughout the United States. Veterinarians (n = 953) were surveyed via a web-based mechanism; completed surveys (n = 308) were analyzed. Results showed that occupational health and safety programs were well-developed, enrolling veterinary, husbandry, and research staff at rates exceeding 90% and involving multiple modalities of health assessments and risk communication for vaccine-preventable diseases. Most (72.7%) institutions did not store serum samples from animal research personnel. More than half of the institutions housed nonhuman primates and maintained tuberculosis screening programs, although screening methods varied. Immunization protocols included various recommended or required vaccines that differed depending on job duties, type of institution, and nature of scientific programs. A single case of an identified vaccine–preventable illness in a laboratory worker was noted. Tetanus toxoid was the predominant vaccine administered (91.7%) to animal care and research workers, followed by hepatitis B (54.8%), influenza (39.9%), and rabies (38.3%). For some immunization protocols, an inconsistent rationale for administration was evident. Indications that animal care and research workers are unprotected from work-related etiologic agents did not emerge from this survey; rather, existing guidelines from the Advisory Committee on Immunization Practices and available biologics seem sufficient to address most needs of the laboratory animal research community. Institutions should commit to performance-based standards in parallel with context-specific risk assessment methods to maintain occupational health and safety programs and practices appropriate to their needs.

Cervical screening programs are highly protective for cervical cancer, but only for women attending screening procedure. Identify socio-economic and demographic determinants for non-attendance in cervical screening. Design: Population-based case-control study. Setting: Sweden. Population: Source population was all women eligible for screening. Based on complete screening records, two groups of women aged 30-60 were compared. The case group, non-attending women, (N = 314,302) had no smear registered for 6-8 years. The control group (N = 266,706) attended within 90 days of invitation. Main outcome measures: Risk of non-attendance by 9 groups of socioeconomic and demographic variables. Analysis: Unadjusted odds ratios (OR) and OR after adjustment for all variables in logistic regression models were calculated. Women with low disposable family income (adjOR 2.06; 95% confidence interval (CI) 2.01-2.11), with low education (adjOR 1.77; CI 1.73-1.81) and not cohabiting (adjOR 1.47; CI 1.45-1.50) were more likely to not attend cervical screening. Other important factors for non-attendance were being outside the labour force and receiving welfare benefits. Swedish counties are responsible for running screening programs; adjusted OR for non-participation in counties ranged from OR 4.21 (CI 4.06-4.35) to OR 0.54 (CI 0.52-0.57), compared to the reference county. Being born outside Sweden was a risk factor for non-attendance in the unadjusted analysis but this disappeared in certain large groups after adjustment for socioeconomic factors. County of residence and socio-economic factors were strongly associated with lower attendance in cervical screening, while being born in another country was of less importance. This indicates considerable potential for improvement of cervical screening attendance in several areas if best practice of routines is adopted.

Objectives Interval colorectal cancer (CRC) after colonoscopy may affect effectiveness and cost-effectiveness of screening programmes. We aimed to investigate whether and how faecal haemoglobin concentration (FHbC) of faecal immunochemical testing (FIT) affected the risk prediction of interval cancer (IC) caused by inadequate colonoscopy quality in a FIT-based population screening programme. Design From 2004 to 2009, 29 969 subjects underwent complete colonoscopy after positive FIT in the Taiwanese Nationwide CRC Screening Program. The IC rate was traced until the end of 2012. The incidence of IC was calculated in relation to patient characteristics, endoscopy-related factors (such adenoma detection rate (ADR)) and FHbC. Poisson regression analysis was performed to assess the potential risk factors for colonoscopy IC. Results One hundred and sixty-two ICs developed after an index colonoscopy and the estimated incidence was 1.14 per 1000 person-years of observation for the entire cohort. Increased risk of IC was most remarkable in the uptake of colonoscopy in settings with ADR lower than 15% (adjusted relative risk (aRR)=3.09, 95% CI 1.55 to 6.18) and then higher FHbC (μg Hb/g faeces) (100–149: aRR=2.55, 95% CI 1.52 to 4.29, ≥150: aRR=2.74, 95% CI 1.84 to 4.09) with adjustment for older age and colorectal neoplasm detected at baseline colonoscopy. Similar findings were observed for subjects with negative index colonoscopy. Conclusions Colonoscopy ICs arising from FIT-based population screening programmes were mainly influenced by inadequate colonoscopy quality and independently predicted by FHbC that is associated with a priori chance of advanced neoplasm. This finding is helpful for future modification of screening logistics based on FHbC. PMID:26515543

Motor vehicle crashes, homicide, suicide, and drug abuse are among the leading causes of pregnancy-associated deaths. To prevent such deaths, identifying women for intervention is required. The universally offered Florida Healthy Start Prenatal Risk Screen was evaluated to identify women at increased risk for traumatic pregnancy-associated death. Florida's Enhanced Maternal Mortality Reporting Database for 1999 through 2005 was linked with Florida's Healthy Start Prenatal Risk Screen to identify traumatic pregnancy-associated death as the outcome. Distribution of Healthy Start risk scores among women who died were compared with the screened population. Traumatic death estimates per 100,000 births were drawn for each risk score, along with estimates of the relative risk (RR) of traumatic death for each score. The RR of women with scores greater than or equal to 4 were compared with the risk of women scoring 0 to 3. Almost 20% of the 620,959 women who did not die of traumatic death had a risk score of 0, compared with only 3% of the 144 women who did die of traumatic death. As risk scores increased, the chance of traumatic deaths sharply increased. A woman with a score of 4 had 11.78 times (confidence interval [CI], 4.63-29.69) the risk of traumatic death compared with a woman with a risk score of 0. The implementation of prenatal risk screening to identify women at increased risk for traumatic pregnancy-associated death would help to ensure that policies to reduce infant risk factors also address maternal risk factors.

The breast cancer screening (BCS) chart is suggested as a basic and preliminary tool to improve efficiency of screening mammography. We conducted this case-control study in 2016 and enrolled 1422 women aged 30-75 years, including 506 women with breast cancer (cases) and 916 women without breast cancer (controls). We developed the BCS chart using a multiple logistic regression analysis. We combined the risks of breast cancer to predict the individual risk of breast cancer. Then, we stratified and colored the predicted risk probabilities as follows: <05% (green), 05-09% (yellow), 10-14% (orange), 15-19% (red), 20-24% (brown) and ≥25% (black). The BCS chart provides the risk probability of breast cancer, based on age, body mass index, late menopause, having a benign breast disease and a positive family history of breast cancer among the first-degree or the second/third-degree relatives. According to this chart, an individual can be classified in a category of low risk (green), medium risk (yellow and orange), high risk (red and brown) and very high risk (black) for breast cancer. This chart is a flexible and easy to use tool that can detect high-risk subjects and make the screening program more efficient and productive. © The Author 2017.

2012-01-01

Background: Reducing the false-positive risk in breast cancer screening is important. We examined how the screening-protocol and women's characteristics affect the cumulative false-positive risk. Methods: This is a retrospective cohort study of 1 565 364 women aged 45–69 years who underwent 4 739 498 screening mammograms from 1990 to 2006. Multilevel discrete hazard models were used to estimate the cumulative false-positive risk over 10 sequential mammograms under different risk scenarios. Results: The factors affecting the false-positive risk for any procedure and for invasive procedures were double mammogram reading [odds ratio (OR) = 2.06 and 4.44, respectively], two mammographic views (OR = 0.77 and 1.56, respectively), digital mammography (OR = 0.83 for invasive procedures), premenopausal status (OR = 1.31 and 1.22, respectively), use of hormone replacement therapy (OR = 1.03 and 0.84, respectively), previous invasive procedures (OR = 1.52 and 2.00, respectively), and a familial history of breast cancer (OR = 1.18 and 1.21, respectively). The cumulative false-positive risk for women who started screening at age 50–51 was 20.39% [95% confidence interval (CI) 20.02–20.76], ranging from 51.43% to 7.47% in the highest and lowest risk profiles, respectively. The cumulative risk for invasive procedures was 1.76% (95% CI 1.66–1.87), ranging from 12.02% to 1.58%. Conclusions: The cumulative false-positive risk varied widely depending on the factors studied. These findings are relevant to provide women with accurate information and to improve the effectiveness of screening programs. PMID:21430183

Many pediatric providers struggle to screen families for the majority of age-appropriate injury risks and educate them when appropriate. Standardized tools have helped physicians provide effective, more purposeful counseling. In this study, pediatricians utilized a standardized, injury prevention screening tool to increase targeted discussions and families were re-screened at subsequent visits to determine changes in their behavior. Pediatric practices, recruited from the Ohio Chapter, American Academy of Pediatrics database, self-selected to participate in a quality improvement program. Two screening tools, for children birth-4 month and 6-12 month, with corresponding talking points, were to be implemented into every well child visit. During the 7-month collaborative, screening results and pediatrician counseling for reported unsafe behaviors were calculated. Patients who completed a screening tool at subsequent visits were followed up at a later visit to determine self-reported behavior changes. We examined statistically significant differences in frequencies using the X 2 test. Providers received maintenance of certification IV credit for participation. Seven practices (39 providers) participated. By the second month, participating providers discussed 75% of all inappropriate responses for birth-4 month screenings and 87% for 6-12 months. Of the 386 families who received specific counseling and had a follow-up visit, 65% (n = 94/144) of birth-4 month and 65% (n = 59/91) of 6-12 month families made at least one behavior change. The X 2 test showed that families who received counseling versus those that did not were significantly more likely to change inappropriate behaviors (p < 0.05). Overall, of all the risks identified, 45% (136) of birth-4 month and 42% (91) of 6-12 month behaviors reportedly changed after a practitioner addressed the topic area. Participation in a quality improvement program within pediatric offices can increase screening for injury risks and encourage tailored injury prevention discussions during an office encounter. As a result, significantly more families reported to practice safer behaviors at later visits.

France is a low-incidence country for tuberculosis (TB). Consequently screening is focused on high-risk populations, in particular migrants. The aim of this study was to evaluate the epidemiology of TB among international exchange students in the Department of Isère and the screening programs used. We carried out an organizational audit based on interviews with physicians involved in the management of TB in Isère. We conducted a retrospective descriptive study based on a case series of foreign students treated for TB from 2003 to 2013 inclusively. Forty-six international exchange students were treated for active TB during this time, representing an average incidence of 284/100,000. Two thirds of our studied population were Africans, 72% were asymptomatic at the time of screening. A quarter of our cohort developed TB after the initial screening. Thirty-one cases were confirmed bacteriologically, mainly through bronchoscopy. Outcome (radiological and clinical) on quadruple therapy was satisfactory in all patients. Two patients relapsed, one of them with multi-drug resistant TB. Our work confirms that international exchange students are a population at high risk of TB and that screening of this population is essential. The significant number of active TB cases diagnosed after the initial screening stresses the importance of diagnosis and follow up of patients with latent TB infection. Copyright © 2017 SPLF.

Greene, Denise; Dell, Richard M

2010-06-01

To detail the outcomes of an osteoporosis disease-management program where nurse practitioners (NPs) have taken a leadership role in screening, diagnosing, and treating patients at risk for osteoporosis. An electronic medical record (EMR) was used to collect demographic, pharmacy, dual x-ray absorptiometry (DXA) scan, and fracture data from a population of over 625,000 patients with one or more risk factors for osteoporosis. Monthly reports were generated and distributed to the NPs to assist them in identifying patients that required screening or treatment. Over a 6-year period there was a 263% increase in the number of screening DXA scans done each year, a 153% increase in the number of patients on anti-osteoporosis medications each year, and a 38.1% decrease in the expected hip fracture rate. NPs play an important leadership role in managing osteoporosis within a large health maintenance organization. The screening and interventions used can be applied by any NP in any practice setting on an individual basis to reduce hip fracture rates in the United States.

Should the Centers for Disease Control and Prevention's childhood lead poisoning intervention level be lowered?

PubMed

Bernard, Susan M

2003-08-01

The US Centers for Disease Control and Prevention (CDC) in 1991 chose 10 micro g/dL as an initial screening level for lead in children's blood. Current data on health risks and intervention options do not support generally lowering that level, but federal lead poisoning prevention efforts can be improved by revising the follow-up testing schedule for infants aged 1 year or less with blood lead levels of 5 micro g/dL or higher; universal education about lead exposure risks; universal administration of improved, locally validated risk-screening questionnaires; enhanced compliance with targeted screening recommendations and federal health program requirements; and development by regulatory agencies of primary prevention criteria that do not use the CDC's intervention level as a target "safe" lead exposure.

Despite evidence of a decline in both incidence and prevalence of colorectal cancer nationwide, it remains the second most commonly diagnosed cancer and the third highest cause of mortality among Asian Americans, including Korean Americans. This community-based and theoretically guided study evaluated a culturally appropriate intervention program that included a bilingual cancer educational program among Korean Americans including information on CRC risks, counseling to address psychosocial and access barriers, and patient navigation assistance. A two-group quasi-experimental design with baseline and post-intervention assessment and a 12-month follow-up on screening was used in the study. Korean Americans (N=167) were enrolled from six Korean churches. The intervention group received culturally appropriate intervention program addressing accessibility and psychosocial barriers, and navigation assistance for screening. The control group received general health education that included cancer-related health issues and screening. There was a significant difference (p<0.05) between the post-intervention and control groups in awareness of CRC risk factors. There was also a significant improvement in the pre-post across HBM measures in the intervention group for perceived susceptibility (p<0.05) and benefits and barriers to screening (p<0.001). At baseline, 13% of participants in the intervention group and 10% in control group reported having had a CRC cancer screening test in the previous year. At the 12-month post-intervention follow-up, 77.4% of participants in the intervention group had obtained screening compared to 10.8% in the control group. While health disparities result from numerous factors, a culturally appropriate and church-based intervention can be highly effective in increasing knowledge of and access to, and in reducing barriers to CRC screening among underserved Koreans.

Physicians in emergency departments (EDs) treat more patients with alcohol-related disorders than do those in primary care settings. To implement an effective screening, brief intervention, and referral (SBIR) program for use in EDs. Further, to evaluate the impact of the program on alcohol-consumption levels. A prospective cohort pilot study was conducted at a suburban community teaching hospital using a convenience sample of ED patients and an original seven-question screening tool based on well-known guidelines. Subjects screening positive for possible alcohol abuse were given treatment referrals. Follow-up telephone interviews were conducted 6 months later. Of the 1556 enrolled subjects, 251 (16%) were classified as at-risk drinkers. Seventy-nine at-risk subjects (32% [95% CI, 26%-37%]) screened positive on CAGE-based questions (Cut down, Annoyed, Guilty, Eye opener). At follow-up, 20 (25% [95% CI, 16%-35%]) were successfully contacted. Of these 20 subjects, 5 (25%) refused to participate in follow-up screening. For the remaining 15 individuals, follow-up screening indicated that the mean (SD) number of drinks consumed per week decreased from 28 (14) on study enrollment to 10 (10) at 6-month follow-up (P<.001). Maximum number of drinks per occasion decreased from 12 (8) at enrollment to 6 (7) on follow-up (P=.008). Subject scores on the CAGE-based questions decreased from pre- to postintervention, though not significantly, with an average of 2.1 (1) affirmative answers on enrollment and 1.5 (1.4) at follow-up (P=.108). Implementation of an effective SBIR program for alcohol-related disorders can be accomplished in the ED.

Implementation of lung cancer screening programs is occurring across the United States. Programs vary in approaches to patient identification and shared decision-making. The eligibility of persons referred to screening programs, the outcomes of eligibility determination during shared decision-making, and the potential for the electronic medical record (EMR) to identify eligible individuals have not been well described. Our objectives were to assess the eligibility of individuals referred for lung cancer screening and compare information extracted from the EMR to information derived from a shared decision-making conversation for the determination of eligibility for lung cancer screening. We performed a retrospective analysis of individuals referred to a centralized lung cancer screening program serving a five-hospital health services system in Seattle, Washington between October 2014 and January 2016. Demographics, referral, and outcomes data were collected. A pack-year smoking history derived from the EMR was compared with the pack-year history obtained during a shared decision-making conversation performed by a licensed nurse professional representing the lung cancer screening program. A total of 423 individuals were referred to the program, of whom 59.6% (252 of 423) were eligible. Of those, 88.9% (224 of 252) elected screening. There was 96.2% (230 of 239) discordance in pack-year smoking history between the EMR and the shared decision-making conversation. The EMR underreported pack-years of smoking for 85.2% (196 of 230) of the participants, with a median difference of 29.2 pack-years. If identification of eligible individuals relied solely on the accuracy of the pack-year smoking history recorded in the EMR, 53.6% (128 of 239) would have failed to meet the 30-pack-year threshold for screening. Many individuals referred for lung cancer screening may be ineligible. Overreliance on the EMR for identification of individuals at risk may lead to missed opportunities for appropriate lung cancer screening.

Factors Influencing Running-Related Musculoskeletal Injury Risk Among U.S. Military Recruits.

PubMed

Molloy, Joseph M

2016-06-01

Running-related musculoskeletal injuries among U.S. military recruits negatively impact military readiness. Low aerobic fitness, prior injury, and weekly running distance are known risk factors. Physical fitness screening and remedial physical training (or discharging the most poorly fit recruits) before entry-level military training have tended to reduce injury rates while decreasing attrition, training, and medical costs. Incorporating anaerobic running sessions into training programs can offset decreased weekly running distance and decrease injury risk. Varying lower extremity loading patterns, stride length or cadence manipulation, and hip stability/strengthening programming may further decrease injury risk. No footstrike pattern is ideal for all runners; transitioning to forefoot striking may reduce risk for hip, knee, or tibial injuries, but increase risk for calf, Achilles, foot or ankle injuries. Minimal evidence associates running surfaces with injury risk. Footwear interventions should focus on proper fit and comfort; the evidence does not support running shoe prescription per foot type to reduce injury risk among recruits. Primary injury mitigation efforts should focus on physical fitness screening, remedial physical training (or discharge for unfit recruits), and continued inclusion of anaerobic running sessions to offset decreased weekly running distance.

2015-06-15

In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancermore » Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical physicist in implementing Lung Cancer Screening protocols for CT, including utilizing resources such as the AAPM Protocols and the ACR Designated Lung Screening Center program.

Higher background parenchymal enhancement (BPE) could be used for stratification of MRI screening programs since it might be related to a higher breast cancer risk. Therefore, the purpose of this study is to correlate BPE to patient and tumor characteristics in women with unilateral MRI-screen detected breast cancer who participated in an intermediate and high risk screening program. As BPE in the affected breast may be difficult to discern from enhancing cancer, we assumed that BPE in the contralateral breast is a representative measure for BPE in women with unilateral breast cancer. This retrospective study was approved by our local institutional board and a waiver for consent was granted. MR-examinations of women with unilateral breast cancers screen-detected on breast MRI were evaluated by two readers. BPE in the contralateral breast was rated according to BI-RADS. Univariate analyses were performed to study associations. Observer variability was computed. Analysis included 77 breast cancers in 76 patients (age: 48±9.8 years), including 62 invasive and 15 pure ductal carcinoma in-situ cases. A negative association between BPE and tumor grade (p≤0.016) and a positive association with progesterone status (p≤0.021) was found. The correlation was stronger when only considering invasive disease. Inter-reader agreement was substantial. Lower BPE in the contralateral breast in women with unilateral breast cancer might be associated to higher tumor grade and progesterone receptor negativity. Great care should be taken using BPE for stratification of patients to tailored screening programs.

How will transitioning from cytology to HPV testing change the balance between the benefits and harms of cervical cancer screening? Estimates of the impact on cervical cancer, treatment rates and adverse obstetric outcomes in Australia, a high vaccination coverage country.

Primary HPV screening enables earlier diagnosis of cervical lesions compared to cytology, however, its effect on the risk of treatment and adverse obstetric outcomes has not been extensively investigated. We estimated the cumulative lifetime risk (CLR) of cervical cancer and excisional treatment, and change in adverse obstetric outcomes in HPV unvaccinated women and cohorts offered vaccination (>70% coverage in 12-13 years) for the Australian cervical screening program. Two-yearly cytology screening (ages 18-69 years) was compared to 5-yearly primary HPV screening with partial genotyping for HPV16/18 (ages 25-74 years). A dynamic model of HPV transmission, vaccination, cervical screening and treatment for precancerous lesions was coupled with an individual-based simulation of obstetric complications. For cytology screening, the CLR of cervical cancer diagnosis, death and treatment was estimated to be 0.649%, 0.198% and 13.4% without vaccination and 0.182%, 0.056% and 6.8%, in vaccinated women, respectively. For HPV screening, relative reductions of 33% and 22% in cancer risk for unvaccinated and vaccinated women are predicted, respectively, compared to cytology. Without the implementation of vaccination, a 4% increase in treatment risk for HPV versus cytology screening would have been expected, implying a possible increase in pre-term delivery (PTD) and low birth weight (LBW) events of 19 to 35 and 14 to 37, respectively, per 100,000 unvaccinated women. However, in vaccinated women, treatment risk will decrease by 13%, potentially leading to 4 to 41 fewer PTD events and from 2 more to 52 fewer LBW events per 100,000 vaccinated women. In unvaccinated women in cohorts offered vaccination as 12-13 year olds, no change to lifetime treatment risk is expected with HPV screening. In unvaccinated women in cohorts offered vaccination as 12-13 year olds, no change to lifetime treatment risk is expected with HPV screening. HPV screening starting at age 25 in populations with high vaccination coverage, is therefore expected to both improve the benefits (further decrease risk of cervical cancer) and reduce the harms (reduce treatments and possible obstetric complications) associated with cervical cancer screening. © 2017 UICC.

To compare the efficacy and cost-effectiveness of two methods of screening for undiagnosed type 2 diabetes in Australian community pharmacy. A random sample of 30 pharmacies were allocated into two groups: (i) tick test only (TTO); or (ii) sequential screening (SS) method. Both methods used the same initial risk assessment for type 2 diabetes. Subjects with one or more risk factors in the TTO group were offered a referral to their general practitioner (GP). Under the SS method, patients with risk factors were offered a capillary blood glucose test and those identified as being at risk referred to a GP. The effectiveness and cost-effectiveness of these approaches was assessed. A total of 1286 people were screened over a period of 3 months. The rate of diagnosis of diabetes was significantly higher for SS compared with the TTO method (1.7% versus 0.2%; p=0.008). The SS method resulted in fewer referrals to the GP and a higher uptake of referrals than the TTO method and so was the more cost-effective screening method. SS is the superior method from a cost and efficacy perspective. It should be considered as the preferred option for screening by community based pharmacists in Australia.

It is unclear whether a woman's age influences her risk of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) upon detection of HPV. A large change in risk as women age would influence vaccination and screening policies. Among 972,029 women age 30-64 undergoing screening with Pap and HPV testing (Hybrid Capture 2, Qiagen, Germantown, MD) at Kaiser Permanente Northern California (KPNC), we calculated age-specific 5-year CIN3+ risks among women with HPV infections detected at enrollment, and among women with "newly detected" HPV infections at their second screening visit. Women (57,899, 6.0%) had an enrollment HPV infection. Among the women testing HPV negative at enrollment with a second screening visit, 16,724 (3.3%) had a newly detected HPV infection at their second visit. Both enrollment and newly detected HPV rates declined with age (p < 0.001). Women with enrollment versus newly detected HPV infection had higher 5-year CIN3+ risks: 8.5% versus 3.9%, (p < 0.0001). Risks did not increase with age but declined slightly from 30-34 years to 60-64 years: 9.4% versus 7.4% (p = 0.017) for enrollment HPV and 5.1% versus 3.5% (p = 0.014) for newly detected HPV. Among women age 30-64 in an established screening program, women with newly detected HPV infections were at lower risk than women with enrollment infections, suggesting reduced benefit vaccinating women at older ages. Although the rates of HPV infection declined dramatically with age, the subsequent CIN3+ risks associated with HPV infection declined only slightly. The CIN3+ risks among older women are sufficiently elevated to warrant continued screening through age 65. © 2014 UICC.

As Newfoundland has the highest rate of familial colorectal cancer (CRC) in the world, we started a population-based clinic to provide colonoscopic and Lynch syndrome (LS) screening recommendations to families of CRC patients based on family risk. Of 1091 incident patients 51% provided a family history. Seventy-two percent of families were at low or intermediate-low risk of CRC and colonoscopic screening recommendations were provided by letter. Twenty-eight percent were at high and intermediate-high risk and were referred to the genetic counsellor, but only 30% (N = 48) were interviewed by study end. Colonoscopy was recommended more frequently than every 5 years in 35% of families. Lower family risk was associated with older age of proband but the frequency of screening colonoscopy recommendations varied across all age groups, driven by variability in family history. Twenty-four percent had a high MMR predict score for a Lynch syndrome mutation, and 23% fulfilled the Provincial Program criteria for LS screening. A population-based approach in the provision of colonoscopic screening recommendations to families at risk of CRC was limited by the relatively low response rate. A family history first approach to the identification of LS families was inefficient. © 2016 The Authors. Clinical Genetics published by John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The population in northeast Thailand continues to present with hepatobiliary abnormalities, particularly periductal fibrosis (PDF) which is the result of chronic infection with liver fluke (Opisthorchis viverini; OV) and may lead to the development of cholangiocarcinoma (CCA). Although the prevalence of OV infection has been decreased due to a liver fluke control program over decades, the prevalence of PDF remains high. This study aimed to investigate demographic factors associated with PDF risk based on ultrasonography (US) screening. This cross-sectional study is part of the Cholangiocarcinoma Screening and Care Program (CASCAP), a prospective cohort study. Multiple logistic regression was used for data analysis. In 55,246 subjects, the overall prevalence of PDF was 33.0% (95%CI: 32.6 - 33.4). Males (33.9 %) were at higher risk for developing PDF than females (32.2 %) (ORcrude = 0.93; 95%CI: 0.89 - 0.96; p-value < 0.001). Factors associated with an increased PDF risk, in addition to OV infection, included old age (≥ 70 years) (ORadj =1.28, 95% CI: 1.14 - 1.44, <0.001) and hepatitis B infection (ORadj = 1.31, 95% CI: 1.11 - 1.55, p = 0.001). In contrast, number of praziquantel treatments (> 2 times) (ORadj = 0.54, 95% CI: 0.47 - 0.63, <0.001) and diabetes mellitus (ORadj =0.57, 95% CI: 0.49 - 0.65, <0.001) were significantly associated with a decreased PDF risk. Future US screening should closely examine older people and hepatitis B subjects for the purpose of PDF surveillance among high risk groups for CCA. However, the results of inverse associations require further investigation in order to confirm our findings.

In 2005, a program named "Early Detection and Early Treatment of Esophageal and Cardiac Cancer" (EDETEC) was initiated in China. A total of 8279 residents aged 40-69 years old were recruited into the EDETEC program in Linzhou of Henan Province between 2005 and 2008. Howerer, the cost-benefit of the EDETEC program is not very clear yet. We conducted herein a cost-benefit analysis of screening for esophageal and cardiac cancer. The assessed costs of the EDETEC program included screening costs for each subject, as well as direct and indirect treatment costs for esophageal and cardiac severe dysplasia and cancer detected by screening. The assessed benefits of this program included the saved treatment costs, both direct and indirect, on esophageal and cardiac cancer, as well as the value of prolonged life due to screening, as determined by the human capital approach. The results showed the screening cost of finding esophageal and cardiac severe dysplasia or cancer ranged from RMB 2707 to RMB 4512, and the total cost on screening and treatment was RMB 13 115-14 920. The cost benefit was RMB 58 944-155 110 (the saved treatment cost, RMB 17 730, plus the value of prolonged life, RMB 41 214-137 380). The ratio of benefit-to-cost (BCR) was 3.95-11.83. Our results suggest that EDETEC has a high benefit-to-cost ratio in China and could be instituted into high risk areas of China.

Early diagnosis of hearing loss minimizes its impact on child development. We studied factors that influence the effectiveness of screening programs. To investigate the relationship between gender, weight at birth, gestational age, risk factors for hearing loss, venue for newborn hearing screening and "pass" and "fail" results in the retest. Prospective cohort study was carried out in a tertiary referral hospital. The screening was performed in 565 newborns through transient evoked otoacoustic emissions in three admission units before hospital discharge and retest in the outpatient clinic. Gender, weight at birth, gestational age, presence of risk indicators for hearing loss and venue for newborn hearing screening were considered. Full-term infants comprised 86% of the cases, preterm 14%, and risk factors for hearing loss were identified in 11%. Considering the 165 newborns retested, only the venue for screening, Intermediate Care Unit, was related to "fail" result in the retest. Gender, weight at birth, gestational age and presence of risk factors for hearing loss were not related to "pass" and/or "fail" results in the retest. The screening performed in intermediate care units increases the chance of continued "fail" result in the Transient Otoacoustic Evoked Emissions test.

Cervical cancer is one of the most common malignancies among women in India. There is a high mortality as patients usually present at an advanced stage because of lack of awareness and nonexistent screening programs. This study was planned to find out awareness about cervical cancer among women and their willingness to utilize screening services in an urban resettlement colony of Delhi, India. A community-based, cross-sectional study was carried out in a resettlement colony of North-West Delhi. Semi-structured interview schedule was used to collect information regarding different aspects of cervical cancer. Analysis was done using SPSS package (SPSS version 16 (UCMS and GTBH, Delhi, India)). A total of 373 women were included in the study. Mean age of study participants was 39.14 years. Two-third of the study population were illiterate. Half of the study population was aware of cervical cancer, and only one-fourth of population were willing to participate in a screening test. Willingness was higher among educated, ever user of family planning method and having knowledge about at least one risk factor, signs or symptoms, or possibility of early diagnosis of cancer cervix. The country's national program advocates for opportunistic and targeted screening of women. An understanding of the factors that influences womens' willingness to participate in screening program is essential for the success of such programs. Hence, this study emphasizes the need for dissemination of knowledge about various aspects of cancer cervix which is critical for uptake of any screening program in a developing country.

Many cardiac rehabilitation (CR) guidelines and position statements recommend screening for psychosocial risk factors, although there is wide variation in the recommended factors and recommended screening tools. Little is known about screening in CR in Australia. Cardiac rehabilitation coordinators at the 314 CR programs operating across Australia, drawn from the 2014 Australian Directory of Cardiac Rehabilitation Services were invited to participate in an online survey. Of 165 complete responses, 157 (95%) CR coordinators indicated that they screened at entry with 132 (80%) screening on exit. At CR entry, programs screened for - depression (83%), anxiety (75%), stress (75%), and sleep disturbance (57%). The use of standardised instruments by those screening at entry varied from 89% for depression to only 9% for sleep disturbance. Organisational, resource and personal barriers inhibited the routine screening for many psychosocial factors. Surveys such as this are useful for monitoring the rate of adoption of guideline recommendations and identifying barriers to implementation. Findings can also inform discussions about what should be included in minimum data sets for CR programs, and the identification of brief screening tools that have been validated not just in the general population but in cardiac patients.

The Value of Lung Cancer CT Screening: It Is All about Implementation.

PubMed

Goulart, Bernardo H L

2015-01-01

Hospitals have been gradually implementing new lung cancer CT screening programs following the release of the U.S. Preventive Services Task Force grade B recommendation to screen individuals at high risk for lung cancer. Policy makers have legitimately questioned whether adoption of CT screening in the community will reproduce the mortality benefits seen in the National Lung Screening Trial (NLST) and whether the benefits of screening will justify the potentially high costs. Although three annual CT screening exams proved cost-effective for the patient population enrolled in the NLST, uncertainty still exists about whether CT screening will be cost-effective in practice. The value of CT screening will depend largely on the strategies used to implement it. This manuscript reviews the current reimbursement policies for CT screening and explains the relationship between implementation strategies and screening value on the basis of the NLST cost-effectiveness analysis and other published data. A subsequent discussion ensues about the potential implementation inefficiencies that can negatively affect the value of CT screening (e.g., selection of low-risk individuals for screening, inappropriate follow-up visits for screening-detected lung nodules, failure to offer smoking cessation interventions, and overuse of medical resources for clinically irrelevant incidental findings) and the actions that can be taken to mitigate these inefficiencies and increase the value of screening.

The US National Lung Screening Trial supports screening for lung cancer among smokers using low-dose computed tomographic (LDCT) scans. The cost-effectiveness of screening in a publically funded health care system remains a concern. To assess the cost-effectiveness of LDCT scan screening for lung cancer within the Canadian health care system. The Cancer Risk Management Model (CRMM) simulated individual lives within the Canadian population from 2014 to 2034, incorporating cancer risk, disease management, outcome, and cost data. Smokers and former smokers eligible for lung cancer screening (30 pack-year smoking history, ages 55-74 years, for the reference scenario) were modeled, and performance parameters were calibrated to the National Lung Screening Trial (NLST). The reference screening scenario assumes annual scans to age 75 years, 60% participation by 10 years, 70% adherence to screening, and unchanged smoking rates. The CRMM outputs are aggregated, and costs (2008 Canadian dollars) and life-years are discounted 3% annually. The incremental cost-effectiveness ratio. Compared with no screening, the reference scenario saved 51,000 quality-adjusted life-years (QALY) and had an incremental cost-effectiveness ratio of CaD $52,000/QALY. If smoking history is modeled for 20 or 40 pack-years, incremental cost-effectiveness ratios of CaD $62,000 and CaD $43,000/QALY, respectively, were generated. Changes in participation rates altered life years saved but not the incremental cost-effectiveness ratio, while the incremental cost-effectiveness ratio is sensitive to changes in adherence. An adjunct smoking cessation program improving the quit rate by 22.5% improves the incremental cost-effectiveness ratio to CaD $24,000/QALY. Lung cancer screening with LDCT appears cost-effective in the publicly funded Canadian health care system. An adjunct smoking cessation program has the potential to improve outcomes.

In screening programs, overdiagnosis is defined as the detection of a disease that would have gone undetected without screening when that disease would not have resulted in morbimortality and was treated unnecessarily. Overdiagnosis is a bias inherent in screening and an undesired effect of secondary prevention and improved sensitivity of diagnostic techniques. It is difficult to discriminate a priori between clinically relevant diagnoses and those in which treatment is unnecessary. To minimize the effects of overdiagnosis, screening should be done in patients at risk. Copyright © 2014 SERAM. Published by Elsevier España, S.L.U. All rights reserved.

Evidence Does Not Support Clinical Screening of Literacy

Wolf, Michael S.

2007-01-01

Limited health literacy is a significant risk factor for adverse health outcomes. Despite controversy, many health care professionals have called for routine clinical screening of patients’ literacy skills. Whereas brief literacy screening tools exist that with further evaluation could potentially be used to detect limited literacy in clinical settings, no screening program for limited literacy has been shown to be effective. Yet there is a noted potential for harm, in the form of shame and alienation, which might be induced through clinical screening. There is fair evidence to suggest that possible harm outweighs any current benefits; therefore, clinical screening for literacy should not be recommended at this time. PMID:17992564

Background Workplaces are one setting for cancer control planners to reach adults at risk for cancer and other chronic diseases. However, the extent to which Centers for Disease Control and Prevention-funded National Comprehensive Cancer Control Programs (NCCCP) implement interventions in the workplace setting is not well characterized. Methods We conducted a qualitative content analysis of program action plans submitted by NCCCP grantees from 2013–2015 to identify and describe cancer prevention objectives and interventions in the workplace setting. Results Nearly half of NCCCP action reports contained at least one cancer prevention objective or intervention in the workplace setting. Common interventions included education about secondhand smoke exposure in the workplace, and the importance of obtaining colorectal cancer screening. Conclusion Workplace interventions were relatively common among NCCCP action plans, and serve as one way to address low percentages of CRC screening, and reduce risk for obesity- and tobacco-related cancers.

Background: This review assessed the performance of patients in NCCN high-risk group 2 in a clinical CT lung screening (CTLS) program. Methods: We retrospectively reviewed screening results for all patients from our institution undergoing clinical CTLS from January 2012 through December 2016, with follow-up through June 2017. To qualify for screening, patients had to meet the NCCN Guidelines high-risk criteria for CTLS, have a physician order for screening, be asymptomatic, be lung cancer-free for 5 years, and have no known metastatic disease. We compared demographics and screening performance of NCCN high-risk groups 1 and 2 across >4 rounds of screening. Screening metrics assessed included rates of positive and suspicious examinations, significant incidental and infectious/inflammatory findings, false negatives, and cancer detection. We also compared cancer stage and histology detected in each NCCN high-risk group. Results: A total of 2,927 individuals underwent baseline screening, of which 698 (24%) were in NCCN group 2. On average, group 2 patients were younger (60.6 vs 63.1 years), smoked less (38.8 vs 50.8 pack-years), had quit longer (18.1 vs 6.3 years), and were more often former smokers (61.4% vs 44.2%). Positive and suspicious examination rates, false negatives, and rates of infectious/inflammatory findings were equivalent in groups 1 and 2 across all rounds of screening. An increased rate of cancer detection was observed in group 2 during the second annual (T2) screening round (2.7% vs 0.5%; P =.005), with no difference in the other screening rounds: baseline (T0; 2% vs 2.3%; P =.61), first annual (T1; 1.2% vs 1.7%; P =.41), and third annual and beyond (≥T3; 1.2% vs 1.1%; P =1.00). Conclusions: CTLS appears to be equally effective in both NCCN high-risk groups. Copyright © 2018 by the National Comprehensive Cancer Network.

At an HIV clinic in the Limpopo province of South Africa, chart reviews revealed long delays in addressing abnormal Pap smears, difficulty in referrals, poor quality and lost results, and increasing cases of cervical cancer. To address these barriers, a "see and treat" approach to screening was proposed. The objective was to integrate this method into current HIV care offered by local providers and to obtain demographic and risk factor data for use in future educational and intervention programs in the region. A cross sectional study of HIV farm workers and at-risk sex workers attending an HIV clinic was performed with visual inspection with acetic acid (VIA). Those with positive screens were offered cryotherapy. Clinic charts were reviewed retrospectively for Pap smear results for the previous year at the time of program initiation and at 12 and 18 months post-program. A total of 403 participants consented and underwent screening with VIA (306 Farm workers and 97 sex workers participated). 83.9% of participants (32.9% sex workers and 100% farm workers) were HIV +. VIA was positive in 30.5% of participants, necessitating cryotherapy. There was no significant difference in VIA positivity between HIV + farm workers and sex workers. There was a positive correlation between Pap smears and VIAs results. We demonstrate successful integration of cervical cancer screening using VIA for HIV + farm workers and sex workers into an existing HIV treatment and prevention clinic in rural South Africa, addressing and treating abnormal results promptly.

Ecological risk assessment for Mather Air Force Base, California: Phase 1, screening assessment

Mather Air Force Base (AFB) is among the numerous facilities scheduled for closure under the US Air Force (USAF) Installation Restoration Program (IRP). A component of the Mather AFB IRP is to prepare risk assessments for each of the chemically contaminated sites. Because no previous ecological risk related studies have been conducted on Mather AFB, the authors proposed a phased approach to assessing ecological risks at the base. Phase 1 consisted of baseline ecological surveys that collected data over a 12-month period. In addition, benchmark screening criteria were used in conjunction with modeling results that utilized measured concentrations of chemicalmore » analytes in abiotic samples. Phase 2 may consist of the collection of more site-specific data and toxicity testing, if warranted by the Phase 1 screening analysis. This approach was in agreement with the USAF`s ecological risk assessment guidance and met the approval of the Air Force and USEPA Region 9. The authors found the use of established and derived screening values to effectively aid in the focusing of the ecological risk assessment on those chemicals most likely to be hazardous to ecological receptors at the base. Disadvantages in the use of screening values include the uncertainties associated with the conservative assumptions inherent in the derivation of benchmark values and the difficulty in extrapolating from laboratory determined benchmark values to impacts in the field.« less

We evaluated long-term survival in attendees and nonattendees of a 1-time screening for prostate cancer. A total of 2,400 men 55 to 70 years old in 1988 were randomly selected and invited to a screening for prostate cancer. Of the invited men 1,782 (74%) attended. Screening attendees were examined with digital rectal examination, transrectal ultrasound and prostate specific antigen analysis. When cancer was suspected, prostate biopsies were taken. A total of 65 men with prostate cancer were detected by this procedure. The entire source population comprising 27,204 men, including 618 nonattendees (26%), was followed for prostate cancer diagnosis and survival for 15 years. Incidence rate ratios were calculated using Poisson regression models. We found no effect of this screening procedure on the risk of death from prostate cancer and other causes of death (incidence rate ratio 1.10, 95% CI 0.83-1.46 and 0.98, 95% CI 0.92-1.05, respectively) when comparing all invited men with the source population. However, attending the screening program was associated with a significantly decreased risk of death from causes other than prostate cancer (vs source population incidence rate ratio 0.82, 95% CI 0.76-0.90). In contrast, the corresponding incidence rate ratio in nonattendees was 1.53 (95% CI 1.37-1.71). We found no evidence of a beneficial effect of this specific screening procedure but strong evidence of a difference in overall survival in screening attendees and nonattendees. These findings should be considered when interpreting previous and upcoming studies of the effect of screening programs.

Selective screening for pancreatic cancer (PC) has been proposed. We describe the establishment of a comprehensive multidisciplinary screening program using 3.0 T MRI. Criteria for screening included the presence of PC in: ≥ 2 first degree relatives (FDR), 1 FDR and 1 s degree relative (SDR), ≥ 3 any degree relatives (ADR), or any known hereditary cancer syndrome with increased PC risk. Imaging with 3.0 T MRI was performed routinely and endoscopic ultrasound was used selectively. Screening was completed in 75 patients (pts). Hereditary cancer syndromes were present in 42 (56%) of the 75 pts: BRCA2 (18), ATM (8), BRCA1 (6), CDKN2A (4), PALB2 (3), Lynch (2), and Peutz-Jeghers (1). A family history of PC was present in ≥ 2 FDR in 12 (16%) pts, 1 FDR and 1 SDR in 5 (7) pts, and ≥ 3 ADR in 16 (21%) pts. Of the 65 pts who received screening MRI, 28 (43%) pts had pancreatic cystic lesions identified, including 1 (1%) patient in whom a cholangiocarcinoma was diagnosed as well. No patient underwent surgical resection. Using a 3.0 T MRI to screen patients at high risk for developing PC identified radiographic abnormalities in 43% of patients, which were stable on subsequent surveillance. Specific guidelines for the frequency of surveillance and indications for surgery remain areas of active investigation as the global experience with high risk screening continues to mature.

Background: Noncommunicable disease (NCDs), psychological, substance use disorders, and stress-related issues have been less understood in Indian industrial settings. Systems for screening and early identification of the above have not been integrated in workplaces, nor there is a strong regulatory backing for the same. Aim: To explore the feasibility of integrating mental health and select NCD risk factor screening with the periodical medical examination of employees. To identify proportion of employees with select NCD risk factors and symptoms suggestive of mental health problems. Settings and Design: Around 10% of employees from a leading motor industry in Bangalore, (706) participated in this cross-sectional voluntary screening program. Materials and Methods: This screening was conducted as a part of their annual medical examination. A mixed method of self-report and interview administered technique was adopted for the same. Statistical Analysis: Descriptive statistical methods (proportions, median, mean, and standard deviation (SD)) and Chi-square test of significance. Results and Conclusions: Screening revealed the following; tobacco use (18%), alcohol use (57%), perceived work stress (10%), and obesity (3%). Nearly 23% screened positive for psychological distress. Time consumed for this assessment was 1–5 min. Initial attempts point out that it is feasible to integrate screening for mental health, substance use, and NCD risk factors in periodic medical examination using a combination of self-report and interview-administered method, though further detailed assessments for confirmation is necessary.

The current pilot study examined the preliminary efficacy of a brief intervention (BI) for at-risk drinking in an employee assistance program. Clients (N = 107) entering the employee assistance program (EAP) for mental health services were screened and met criteria for at-risk drinking. EAP therapists were randomly assigned to deliver either the BI plus EAP services as usual (SAU) or SAU only. Participants in the final analyses consisted of 44 BI + SAU (30 women, 14 men) and 30 SAU (21 women, 9 men) EAP clients who completed a 3-month follow-up. Results suggested that participants in the BI + SAU group had significant reductions in peak blood alcohol concentration, peak quantity, and alcohol-related consequences compared with the SAU group. Men in the BI + SAU group had greater reductions in alcohol-related problems compared with men in the SAU group. Groups did not differ by number of total EAP sessions attended or rates of presenting problem resolution. Results provide preliminary evidence to support the integration of alcohol screening and BI as a low-cost method of intervening with clients with at-risk drinking in the context of co-occurring presenting problems.

Although the number of Arab Americans is growing in the United States, there is very little data available on this population's cancer incidence and screening practices. Moreover, there are few interventions addressing their unique needs. This study aims to determine effective strategies for increasing breast cancer screening in at-risk underserved Arab American women. AMBER utilizes a community based participatory approach to conduct formative research and program interventions, including culturally appropriate Arabic language breast cancer education, screening coordination, and cultural competency training for healthcare professionals in New York City. In 2 years, 597 women were educated, 189 underserved women were identified as being in need of assistance, 68 were screened, one new case of breast cancer was detected, and four active cases in need of follow-up reconnected with care. The AMBER model is an important intervention for breast cancer screening and care in the underserved Arab American community.

The overall prognosis of lung cancer is poor: Only every 8 patient survives 5 years after diagnosis. This outcome is partly attributable to late diagnosis. To implement a screening program for early diagnosis, selection of high-risk individuals is essential. Our aim was to construct a personalized lung cancer risk assessment tool using geographic localization to lead the high-risk individuals to the local health care provider. A smartphone application was created for Android and iOS mobile platforms using a risk assessment questionnaire. The software provides immediate classification into low, moderate and high-risk groups. The high-risk group is directed to the nearest screening centre based on GPS location. The complete test data set is recorded on a collection server database for further analysis. The application was downloaded 13 890 times and completed by 89 500 persons over a period of 20 months. The mean age of the tested users was 36.91 years (9-93 years); the majority were men living in an urban area (62.3%). The test was completed by 38 850 active smokers and 26 710 persons who reported having already quit smoking, resulting in 30 072 moderate and 10 740 high-risk users. This free application is an active communication tool for most smartphone owners. It helps those who might need further medical attention. The affected users can be easily connected and localized via the smartphone, which helps recruit individuals into screening programs. © The Author 2017.

Introduction The TMPRSS2-ERG gene fusion occurs in >50% of prostate tumors and has been associated with poor outcomes. The T-allele (Valine) of the Met160Val (rs12329760) in TMPRSS2 has been associated with this fusion. We evaluated this polymorphism with respect to self-identified race or ethnicity (SIRE), time to prostate cancer (PCA) diagnosis, and screening parameters in the Prostate Cancer Risk Assessment Program, a prospective screening program for high-risk men. Patients and Methods 631 men ages 35-69 years were studied. “High-risk” was defined as ≥ one first degree or two second degree relatives with PCA, any African American (AA) man regardless of familial PCA, and men with BRCA1/2 mutations. Men with elevated PSA or other indications for PCA underwent biopsy. Men were followed from time of study entry to PCA diagnosis. Cox models were used to evaluate time to PCA diagnosis by genotype. Results Genotype distribution differed significantly by SIRE (CT/TT vs. CC, p<0.0001). Among 183 Caucasian men with at least one follow-up visit, PCA was more than doubled in men carrying CT/TT vs CC genotypes (HR= 2.55, 95% CI=1.14-5.70) after controlling for age and PSA. No association was seen among AA men by TMPRSS2 genotype. Conclusions The T-allele of the Met160Val variant in TMPRSS2, which has been associated with the TMPRSS2-ERG fusion, may be informative of time to PCA diagnosis for a subset of high-risk Caucasian men who are undergoing regular PCA screening. This variant along with other genetic markers warrant further study for personalizing PCA screening. PMID:20735386

Objectives The incidence of sensorineural hearing loss is between 1 and 3 per 1000 in healthy neonates and 2–4 per 100 in high-risk infants. The national universal neonatal hearing screening carried out in Poland since 2002 enables selection of infants with suspicion and/or risk factors of hearing loss. In this study, we assessed the incidence and risk factors of hearing impairment in infants ≤33 weeks’ gestational age (wga). Methods We analyzed the database of the Polish Universal Newborns Hearing Screening Program from 2010 to 2013. The study group involved 11438 infants born before 33 wga, the control group—1487730 infants. Screening was performed by means of transient evoked otoacoustic emissions. The risk factors of hearing loss were recorded. Infants who failed the screening test and/or had risk factors were referred for further audiological evaluation. Results Hearing deficit was diagnosed in 11% of infants ≤25 wga, 5% at 26–27 wga, 3.46% at 28 wga and 2–3% at 29–32 wga. In the control group the incidence of hearing deficit was 0.2% (2.87% with risk factors). The most important risk factors were craniofacial malformations, very low birth weight, low Apgar score and mechanical ventilation. Hearing screening was positive in 22.42% newborns ≤28 wga and 10% at 29–32 wga and in the control group. Conclusions Hearing impairment is a severe consequence of prematurity. Its prevalence is inversely related to the maturity of the baby. Premature infants have many concomitant risk factors which influence the occurrence of hearing deficit. PMID:28910311

Background: Lung cancer is by far the major cause of cancer deaths largely because in the majority of patients it is at an advanced stage at the time it is discovered, when curative treatment is no longer feasible. This article examines the data regarding the ability of screening to decrease the number of lung cancer deaths. Methods: A systematic review was conducted of controlled studies that address the effectiveness of methods of screening for lung cancer. Results: Several large randomized controlled trials (RCTs), including a recent one, have demonstrated that screening for lung cancer using a chest radiograph does not reduce the number of deaths from lung cancer. One large RCT involving low-dose CT (LDCT) screening demonstrated a significant reduction in lung cancer deaths, with few harms to individuals at elevated risk when done in the context of a structured program of selection, screening, evaluation, and management of the relatively high number of benign abnormalities. Whether other RCTs involving LDCT screening are consistent is unclear because data are limited or not yet mature. Conclusions: Screening is a complex interplay of selection (a population with sufficient risk and few serious comorbidities), the value of the screening test, the interval between screening tests, the availability of effective treatment, the risk of complications or harms as a result of screening, and the degree with which the screened individuals comply with screening and treatment recommendations. Screening with LDCT of appropriate individuals in the context of a structured process is associated with a significant reduction in the number of lung cancer deaths in the screened population. Given the complex interplay of factors inherent in screening, many questions remain on how to effectively implement screening on a broader scale. PMID:23649455

Current U.S. cervical cancer screening and management guidelines do not consider previous screening history, because data on multiple-round human papillomavirus (HPV) and cytology "co-testing" have been unavailable. To measure cervical cancer risk in routine practice after successive negative screening co-tests at 3-year intervals. Observational cohort study. Integrated health care system (Kaiser Permanente Northern California, Oakland, California). 990 013 women who had 1 or more co-tests from 2003 to 2014. 3- and 5-year cumulative detection of (risk for) cervical intraepithelial neoplasia grade 3, adenocarcinoma in situ, and cervical cancer (≥CIN3) in women with different numbers of negative co-tests, overall and within subgroups defined by previous co-test results or baseline age. Five-year ≥CIN3 risks decreased after each successive negative co-test screening round (0.098%, 0.052%, and 0.035%). Five-year ≥CIN3 risks for an HPV-negative co-test, regardless of the cytology result, nearly matched the performance (reassurance) of a negative co-test for each successive round of screening (0.114%, 0.061%, and 0.041%). By comparison, ≥CIN3 risks for the cytology-negative co-test, regardless of the HPV result, also decreased with each successive round, but 3-year risks were as high as 5-year risks after an HPV-negative co-test (0.199%, 0.065%, and 0.043%). No interval cervical cancer cases were diagnosed after the second negative co-test. Independently, ≥CIN3 risks decreased with age. Length of previous screening interval did not influence future ≥CIN3 risks. Interval-censored observational data. After 1 or more negative cervical co-tests (or HPV tests), longer screening intervals (every 5 years or more) might be feasible and safe. National Cancer Institute Intramural Research Program.

At this time, there is limited scientific knowledge about women who exclude themselves from screening programs for postnatal depression. In this retrospective descriptive study, we have sought to investigate the socio-demographic and psycho-social factors of women who withdraw from PND screening of their own accord. Study participants were 525 women attending antenatal classes who later took part in institutional routine screening for PND at the Consultorio Familiare Service of the National Health Service, Italy. The PND screening program consisted of the completion of the postpartum depression predictors inventory-revised and psychological well-being (PWB) questionnaires within eight to nine months of pregnancy, and Edinburgh Postnatal Depression Scale, GHQ-12 and PWB within six to eight weeks after childbirth. The Responders group was made up of 346 subjects - 65.9% of the total sample - who completed the entire program of screening for PND. The Non-Responders group, on the other hand, consisted of 179 subjects - 34.1% of the total sample - who, after childbirth, withdrew from the screening program. Compared to the Responders group, the Non-Responders group showed a greater number of subjects with marital dissatisfaction, and with unemployment as a stressful event. Health professionals who detect marital dissatisfaction and/or unemployment as a stressful event in pregnant women should bear in mind that these individuals, besides being at high risk for depression after delivery, will also tend to exclude themselves from screening for PND.

Women with a genetic predisposition to breast cancer tend to develop the disease at a younger age with denser breasts making mammography screening less effective. The introduction of magnetic resonance imaging (MRI) for familial breast cancer screening programs in recent years was intended to improve outcomes in these women. We aimed to assess whether introduction of MRI surveillance improves 5- and 10-year survival of high-risk women and determine the accuracy of MRI breast cancer detection compared with mammography-only or no enhanced surveillance and compare size and pathology of cancers detected in women screened with MRI + mammography and mammography only. We used data from two prospective studies where asymptomatic women with a very high breast cancer risk were screened by either mammography alone or with MRI also compared with BRCA1/2 carriers with no intensive surveillance. 63 cancers were detected in women receiving MRI + mammography and 76 in women receiving mammography only. Sensitivity of MRI + mammography was 93 % with 63 % specificity. Fewer cancers detected on MRI were lymph node positive compared to mammography/no additional screening. There were no differences in 10-year survival between the MRI + mammography and mammography-only groups, but survival was significantly higher in the MRI-screened group (95.3 %) compared to no intensive screening (73.7 %; p = 0.002). There were no deaths among the 21 BRCA2 carriers receiving MRI. There appears to be benefit from screening with MRI, particularly in BRCA2 carriers. Extended follow-up of larger numbers of high-risk women is required to assess long-term survival.

Youth with learning and behavioral problems are at elevated risk for substance use during adolescence. Although evidence-based substance use prevention and screening practices are described in the literature, the extent with which these are provided to these youth is unclear. Mental health professionals in schools and community mental health centers are in an ideal position to conduct substance use screening and prevention practices since they have frequent contact with this high risk group. In order to determine whether these mental health professionals were using evidence based substance use screening and prevention programs with these youth, we analyzed 345 completed surveys from mental health professionals in schools and community clinics throughout a mid-Atlantic state. Results indicated that a large portion of the respondents were unfamiliar with evidence based practices and they were infrequently used. Implications for the division of labor at schools and community mental health centers are discussed in relation to time allotment and priority for these procedures.

Studies done in the mid-1970s documented increased risk for respiratory cancer and leukemia among employees in a chemical company manufacturing plant where chloromethyl ethers were used in production from 1948 to 1971. In the late 1980s, the company informed current and former employees about the results of follow-up studies which showed a moderation of risk of respiratory cancer and leukemia. New data showing elevated rates of mortality from colorectal, prostate, bladder, and pancreatic cancer in the population were also reported. Via mailed correspondence, the company made a no-cost program of colorectal and prostate cancer screening available to employees upon request; and information about bladder and pancreatic cancer was made available. Thirteen percent of employees in the population indicated interest in colorectal and prostate cancer screening (response). Thirty-one percent of these responders were screened (adherence). Multivariate analyses showed that education and length of employment in the plant were positively associated with response. Being white was positively associated with response for younger workers; while among older workers being male was positively associated with response. In terms of adherence, we found that older, more highly educated workers were more likely to have a screening examination. Findings indicate that employee participation in workplace-sponsored colorectal and prostate cancer screening can vary according to worker sociodemographic factors and length of employment in areas of potential exposure.

Should the Centers for Disease Control and Prevention’s Childhood Lead Poisoning Intervention Level Be Lowered?

The US Centers for Disease Control and Prevention (CDC) in 1991 chose 10 μg/dL as an initial screening level for lead in children’s blood. Current data on health risks and intervention options do not support generally lowering that level, but federal lead poisoning prevention efforts can be improved by revising the follow-up testing schedule for infants aged 1 year or less with blood lead levels of 5 μg/dL or higher; universal education about lead exposure risks; universal administration of improved, locally validated risk-screening questionnaires; enhanced compliance with targeted screening recommendations and federal health program requirements; and development by regulatory agencies of primary prevention criteria that do not use the CDC’s intervention level as a target “safe” lead exposure.

Expanded newborn screening: social and ethical issues.

PubMed

Dhondt, Jean-Louis

2010-10-01

Newborn screening and genetic testing have expanded rapidly in the last decade with the advent of multiplex (e.g., tandem mass spectrometry) and/or DNA technologies. However, screening panels include a large number of disorders, which may not meet all of the traditional screening criteria, established in late 1960s, and used for years to justify screening programs. After a period of expansion driven by technological advances, many reports have reconsidered the justification of expanded programs. Many factors have contributed to test-panel discrepancies between countries. The test-panel review methodology, the way health benefits are weighed against harms, and the socioeconomic-political environment all play a role. Expansion of screening also requires reconsideration of the infrastructure (ideally, in the context of national plans for rare diseases) to support testing, counselling, education, treatment, and follow-up. Consequently, economic aspects cannot be ignored and can be a limitation for expansion. New ethical questions have emerged: risks of discrimination or stigmatization, respect of the autonomy of persons to make decisions, parental anxiety resulting from a false positive test (especially when reporting to parents screening results for untreatable conditions identified as by-products of screening), etc. For disorders where there is not yet confirmation of benefit, it may be prudent to recommend pilot screening and to have a mechanism that can be used to adapt or even to stop a program.

Anal intraepithelial neoplasia: A review of diagnosis and management

PubMed Central

Roberts, Joseph R; Siekas, Lacey L; Kaz, Andrew M

2017-01-01

Anal intraepithelial neoplasia (AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus (HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior. A history of HPV-mediated genital cancer, which suggests infection with an oncogenic HPV strain, is another risk factor for AIN/anal cancer. Because progression of AIN to anal cancer is known to occur in some individuals over several years, screening for AIN and early anal cancer, as well as treatment of advanced AIN lesions, is reasonable in certain high-risk populations. Although randomized controlled trials evaluating screening and treatment outcomes are lacking, experts support routine screening for AIN in high risk populations. Screening is performed using anal cytological exams, similar to those performed in cervical cancer screening programs, along with direct tissue evaluation and biopsy via high resolution anoscopy. AIN can be treated using topical therapies such as imiquimod, 5-flurouracil, and trichloroacetic acid, as well as ablative therapies such as electrocautery and laser therapy. Reductions in AIN and anal cancer rates have been shown in studies where high-risk populations were vaccinated against the oncogenic strains of HPV. Currently, the CDC recommends both high-risk and average-risk populations be vaccinated against HPV infection using the quadrivalent or nonavalent vaccines. It is important for clinicians to be familiar with AIN and the role of HPV vaccination, particularly in high risk populations. PMID:28255426

Objective To calculate the yield and cost per diagnosed tuberculosis (TB) case for three World Health Organization screening algorithms and one using the Chinese National TB program (NTP) TB suspect definitions, using data from a TB prevalence survey of people aged 65 years and over in China, 2013. Methods This was an analytic study using data from the above survey. Risk groups were defined and the prevalence of new TB cases in each group calculated. Costs of each screening component were used to give indicative costs per case detected. Yield, number needed to screen (NNS) and cost per case were used to assess the algorithms. Findings The prevalence survey identified 172 new TB cases in 34,250 participants. Prevalence varied greatly in different groups, from 131/100,000 to 4651/ 100,000. Two groups were chosen to compare the algorithms. The medium-risk group (living in a rural area: men, or previous TB case, or close contact or a BMI <18.5, or tobacco user) had appreciably higher cost per case (USD 221, 298 and 963) in the three algorithms than the high-risk group (all previous TB cases, all close contacts). (USD 72, 108 and 309) but detected two to four times more TB cases in the population. Using a Chest x-ray as the initial screening tool in the medium risk group cost the most (USD 963), and detected 67% of all the new cases. Using the NTP definition of TB suspects made little difference. Conclusions To “End TB”, many more TB cases have to be identified. Screening only the highest risk groups identified under 14% of the undetected cases,. To “End TB”, medium risk groups will need to be screened. Using a CXR for initial screening results in a much higher yield, at what should be an acceptable cost. PMID:28594824

The increasing incidence of testicular germ cell tumour (TGCT) combined with its strong heritable basis suggests that stratified screening for the early detection of TGCT may be clinically useful. We modelled the efficiency of such a personalised screening approach, based on genetic risk profiling in combination with other diagnostic tools. We compared the number of cases potentially detectable in the population under a number of screening models. The polygenic risk scoring (PRS) model was assumed to have a log-normal relative risk distribution across the 19 currently known TGCT susceptibility variants. The diagnostic performance of testicular biopsy and non-invasive semen analysis was also assessed, within a simulated combined screening programme. The area under the curve for the TGCT PRS model was 0.72 with individuals in the top 1% of the PRS having a nine-fold increased TGCT risk compared with the population median. Results from population-screening simulations only achieved a maximal positive predictive value (PPV) of 60%, highlighting broader clinical factors that challenge such strategies, not least the rare nature of TGCT. In terms of future improvements, heritability estimates suggest that a significant number of additional genetic risk factors for TGCT remain to be discovered, identification of which would potentially yield improvement of the PPV to 80-90%. While personalised screening models may offer enhanced TGCT risk discrimination, presently the case for population-level testing is not compelling. However, future advances, such as more routine generation of whole genome data is likely to alter the landscape. More targeted screening programs may plausibly then offer clinical benefit, particularly given the significant survivorship issues associated with the successful treatment of TGCT.

Newborn hearing screening update for midwifery practice.

PubMed

Narrigan, D

2000-01-01

Neonatal identification of congenital hearing impairment allows interventions during the first 3 years, the critical period for language and speech development. Two recently developed biophysical testing methods offer simple, accurate, and relatively inexpensive means to identify the one to three in 1,000 healthy newborns with hearing loss. Universal screening for auditory system integrity is advocated, because almost half of all newborns with hearing impairment have no risk factors associated with this impairment. Critics of universal screening cite the high rate of false positive tests (up to 7%), which increases program costs from follow-up and re-testing large numbers of infants to ensure identifying the few affected infants. As of early 2000, 24 states had introduced some type of auditory screening program, and the U.S. Congress had passed legislation with appropriations mandating state-based auditory screening for all newborns. Midwives practicing in states already mandating biophysical screening need to comply with their local requirements; those in other states may voluntarily incorporate new auditory test methods into practice.

We used administrative and screening data from 2009 to 2010 to determine if Healthy Start (HS), an enhanced prenatal services program, is reaching the most vulnerable African American women in Kent County, Michigan. Women in HS are at higher risk of key predictors of birth outcomes compared with other women. To advance toward evidence-based HS program evaluations in the absence of randomized controlled trials, future studies using comparison groups need to appropriately establish baseline equivalence on a variety of risk factors related to birth outcomes.

Updating ACSM's Recommendations for Exercise Preparticipation Health Screening.

The purpose of the American College of Sports Medicine's (ACSM) exercise preparticipation health screening process is to identify individuals who may be at elevated risk for exercise-related sudden cardiac death and/or acute myocardial infarction. Recent studies have suggested that using the current ACSM exercise preparticipation health screening guidelines can result in excessive physician referrals, possibly creating a barrier to exercise participation. In addition, there is considerable evidence that exercise is safe for most people and has many associated health and fitness benefits; exercise-related cardiovascular events are often preceded by warning signs/symptoms; and the cardiovascular risks associated with exercise lessen as individuals become more physically active/fit. Consequently, a scientific roundtable was convened by the ACSM in June 2014 to evaluate the current exercise preparticipation health screening recommendations. The roundtable proposed a new evidence-informed model for exercise preparticipation health screening on the basis of three factors: 1) the individual's current level of physical activity, 2) presence of signs or symptoms and/or known cardiovascular, metabolic, or renal disease, and 3) desired exercise intensity, as these variables have been identified as risk modulators of exercise-related cardiovascular events. Identifying cardiovascular disease risk factors remains an important objective of overall disease prevention and management, but risk factor profiling is no longer included in the exercise preparticipation health screening process. The new ACSM exercise preparticipation health screening recommendations reduce possible unnecessary barriers to adopting and maintaining a regular exercise program, a lifestyle of habitual physical activity, or both, and thereby emphasize the important public health message that regular physical activity is important for all individuals.

In the United States, the lifetime risk of being diagnosed with prostate cancer is approximately 13%, and the lifetime risk of dying of prostate cancer is 2.5%. The median age of death from prostate cancer is 80 years. Many men with prostate cancer never experience symptoms and, without screening, would never know they have the disease. African American men and men with a family history of prostate cancer have an increased risk of prostate cancer compared with other men. To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on prostate-specific antigen (PSA)-based screening for prostate cancer. The USPSTF reviewed the evidence on the benefits and harms of PSA-based screening for prostate cancer and subsequent treatment of screen-detected prostate cancer. The USPSTF also commissioned a review of existing decision analysis models and the overdiagnosis rate of PSA-based screening. The reviews also examined the benefits and harms of PSA-based screening in patient subpopulations at higher risk of prostate cancer, including older men, African American men, and men with a family history of prostate cancer. Adequate evidence from randomized clinical trials shows that PSA-based screening programs in men aged 55 to 69 years may prevent approximately 1.3 deaths from prostate cancer over approximately 13 years per 1000 men screened. Screening programs may also prevent approximately 3 cases of metastatic prostate cancer per 1000 men screened. Potential harms of screening include frequent false-positive results and psychological harms. Harms of prostate cancer treatment include erectile dysfunction, urinary incontinence, and bowel symptoms. About 1 in 5 men who undergo radical prostatectomy develop long-term urinary incontinence, and 2 in 3 men will experience long-term erectile dysfunction. Adequate evidence shows that the harms of screening in men older than 70 years are at least moderate and greater than in younger men because of increased risk of false-positive results, diagnostic harms from biopsies, and harms from treatment. The USPSTF concludes with moderate certainty that the net benefit of PSA-based screening for prostate cancer in men aged 55 to 69 years is small for some men. How each man weighs specific benefits and harms will determine whether the overall net benefit is small. The USPSTF concludes with moderate certainty that the potential benefits of PSA-based screening for prostate cancer in men 70 years and older do not outweigh the expected harms. For men aged 55 to 69 years, the decision to undergo periodic PSA-based screening for prostate cancer should be an individual one and should include discussion of the potential benefits and harms of screening with their clinician. Screening offers a small potential benefit of reducing the chance of death from prostate cancer in some men. However, many men will experience potential harms of screening, including false-positive results that require additional testing and possible prostate biopsy; overdiagnosis and overtreatment; and treatment complications, such as incontinence and erectile dysfunction. In determining whether this service is appropriate in individual cases, patients and clinicians should consider the balance of benefits and harms on the basis of family history, race/ethnicity, comorbid medical conditions, patient values about the benefits and harms of screening and treatment-specific outcomes, and other health needs.

In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancermore » Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical physicist in implementing Lung Cancer Screening protocols for CT, including utilizing resources such as the AAPM Protocols and the ACR Designated Lung Screening Center program. UCLA Department of Radiology has an Institutional research agreement with Siemens Healthcare; Dr. McNitt-Gray has been a recipient of Research Support from Siemens Healthcare in the past.

Evaluation improves efficiency and effectiveness. Current U.S. tuberculosis (TB) control policies emphasize the treatment of latent TB infection (LTBI). However, this policy, if not targeted, may be inefficient. We determined the efficiency of a state-law mandated TB screening program and a non state-law mandated one in terms of cost, morbidity, treatment, and disease averted. We evaluated two publicly funded metropolitan TB prevention and control programs through retrospective analyses and modeling. Main outcomes measured were TB incidence and prevalence, TB cases averted, and cost. A non state-law mandated TB program for homeless persons in Tarrant County screened 4.5 persons to identify one with LTBI and 82 persons to identify one with TB. A state-law mandated TB program for jail inmates screened 109 persons to identify one with LTBI and 3274 persons to identify one with TB. The number of patients with LTBI treated to prevent one TB case was 12.1 and 15.3 for the homeless and jail inmate TB programs, respectively. Treatment of LTBI by the homeless and jail inmate TB screening programs will avert 11.9 and 7.9 TB cases at a cost of 14,350 US dollars and 34,761 US dollars per TB case, respectively. Mandated TB screening programs should be risk-based, not population-based. Non mandated targeted testing for TB in congregate settings for the homeless was more efficient than state-law mandated targeted testing for TB among jailed inmates.

Women with a strong family history of breast cancer (BC) and without a known gene mutation have an increased risk of developing BC. We aimed to investigate the accuracy of screening using annual mammography with or without magnetic resonance imaging (MRI) for these women outside the general population screening program. An individual patient data (IPD) meta-analysis was conducted using IPD from six prospective screening trials that had included women at increased risk for BC: only women with a strong familial risk for BC and without a known gene mutation were included in this analysis. A generalised linear mixed model was applied to estimate and compare screening accuracy (sensitivity, specificity and predictive values) for annual mammography with or without MRI. There were 2226 women (median age: 41 years, interquartile range 35-47) with 7478 woman-years of follow-up, with a BC rate of 12 (95% confidence interval 9.3-14) in 1000 woman-years. Mammography screening had a sensitivity of 55% (standard error of mean [SE] 7.0) and a specificity of 94% (SE 1.3). Screening with MRI alone had a sensitivity of 89% (SE 4.6) and a specificity of 83% (SE 2.8). Adding MRI to mammography increased sensitivity to 98% (SE 1.8, P < 0.01 compared to mammography alone) but lowered specificity to 79% (SE 2.7, P < 0.01 compared with mammography alone). In this population of women with strong familial BC risk but without a known gene mutation, in whom BC incidence was high both before and after age 50, adding MRI to mammography substantially increased screening sensitivity but also decreased its specificity.

Objectives To enhance students' learning and confidence in their abilities to provide wellness screenings and disease counseling. Design An experiential rotation was implemented in January 2004 within the Center for Pharmacy Care, a pharmacist-coordinated, University-based wellness center that offers preventive health screenings, risk assessments, patient education, medication and lifestyle counseling, educational seminars, and referral for common health conditions, such as hypertension, diabetes and osteoporosis. Assessment A brief survey instrument consisting of both open-ended questions and ratings of perceived abilities and confidence to provide screening and counseling was administered to students prior to and upon completion of the experience. Results of the survey indicate that the experience significantly enhanced students' preparedness and confidence to conduct community-based wellness screenings. Conclusion Students gained confidence in implementing and conducting wellness programs and became motivated to incorporate such programs into their future practice. This experience can serve as a teaching model for other programs to achieve student conpetencies in helath promotion and disease prevention. PMID:17619649

To evaluate the performance of an automated computer-aided detection (CAD) system to detect breast cancers that were overlooked or misinterpreted in a breast MRI screening program for women at increased risk. We identified 40 patients that were diagnosed with breast cancer in MRI and had a prior MRI examination reported as negative available. In these prior examinations, 24 lesions could retrospectively be identified by two breast radiologists in consensus: 11 were scored as visible and 13 as minimally visible. Additionally, 120 normal scans were collected from 120 women without history of breast cancer or breast surgery participating in the same MRI screening program. A fully automated CAD system was applied to this dataset to detect malignant lesions. At 4 false-positives per normal case, the sensitivity for the detection of cancer lesions that were visible or minimally visible in retrospect in prior-negative examinations was 0.71 (95% CI=0.38-1.00) and 0.31 (0.07-0.59), respectively. A substantial proportion of cancers that were misinterpreted or overlooked in an MRI screening program was detected by a CAD system in prior-negative examinations. It has to be clarified with further studies if such a CAD system has an influence on the number of misinterpreted and overlooked cancers in clinical practice when results are given to a radiologist.

Sickle cell anemia is a hemolytic anemia caused by a single mutation in position 6 of the beta globin molecule. About 80 patients with SCA in northern Israel are currently receiving treatment. To assess a screening program in northern Israel aimed at detecting couples at risk for having offspring with SCA. Since 1987, screening for beta thalassemia in pregnant women in northern Israel has been conducted, and from 1999 all the samples were also tested for hemoglobin S, Hgb C, Hgb D, Hgb O Arab and others. During the 20 year period 1987-2006 a total of 69,340 women were screened; 114 couples who carried Hgb S were detected and 187 prenatal diagnoses were performed in couples at risk for having an offspring with Hgb S. The mean gestational age was 13 +/- 4 weeks. Fifty-four of those diagnoses revealed affected fetuses and in 4 cases the couple declined to perform therapeutic abortion. The economic burden to the health services for treating SCA patients is about U.S.$ 7000 per year, and the institution of prevention programs has proven cost-effective in populations with a high frequency of carriers. Since our program is aimed to also detect beta thalassemia, a disease that is more frequent in this area (> 2.5%), the added cost for the prevention of SCA is less significant despite the low incidence of the S gene in our population, namely < 1%.

To estimate the benefits, cost-effectiveness (i.e., value for money), and required financial costs (e.g., affordability) of adding human papillomavirus (HPV) vaccination to Peru's cervical cancer screening program. Evidence (e.g., coverage, delivery costs) from an HPV vaccination demonstration project conducted in Peru was combined with epidemiological data in an empirically calibrated mathematical model to assess screening (HPV DNA testing three to five times per lifetime) and HPV vaccination under different cost, coverage, and efficacy assumptions. Model outcomes included lifetime risk of cancer reduction, cancer cases averted, lives saved, average life expectancy gains, short-term financial costs, and discounted long-term economic costs. Status quo low levels of screening (e.g., cytologic screening at 10.0% coverage) reduced lifetime risk of cervical cancer by 11.9%, compared to not screening. Adding vaccination of preadolescent girls at a coverage achieved in the demonstration program (82.0%) produced an additional 46.1% reduction, and would cost less than US$ 500 per year of life saved (YLS) at ~US$ 7/dose or ~US$ 1 300 at ~US$ 20/dose. One year of vaccination was estimated to cost ~US$ 5 million at ~US$ 5/dose or ~US$ 16 million at ~US$ 20/dose, including programmatic costs. Enhanced screening in adult women combined with preadolescent vaccination had incremental cost-effectiveness ratios lower than Peru's 2005 per capita gross domestic product (GDP; US$ 2 852, in 2009 US$), and would be considered cost-effective. Preadolescent HPV vaccination, followed by enhanced HPV DNA screening in adult women, could prevent two out of three cervical cancer deaths. Several strategies would be considered "good value" for resources invested, provided vaccine prices are low. While financial costs imply substantial immediate investments, the high-value payoff should motivate creative mechanisms for financing and scale-up of delivery programs.

Seniors represent the fasting growing population in the U.S., accounting for 20.3 million visits to emergency departments (EDs) annually. The ED visit can provide an opportunity for identifying seniors at high risk of falls. We sought to incorporate the Timed Up & Go Test (TUGT), a commonly used falls screening tool, into the ED encounter to identify seniors at high fall risk and prompt interventions through a geriatric nurse liaison (GNL) model. Patients aged 65 and older presenting to an urban ED were evaluated by a team of ED nurses trained in care coordination and geriatric assessment skills. They performed fall risk screening with the TUGT. Patients with abnormal TUGT results could then be referred to physical therapy (PT), social work or home health as determined by the GNL. Gait assessment with the TUGT was performed on 443 elderly patients between 4/1/13 and 5/31/14. A prior fall was reported in 37% of patients in the previous six months. Of those screened with the TUGT, 368 patients experienced a positive result. Interventions for positive results included ED-based PT (n=63, 17.1%), outpatient PT referrals (n=56, 12.2%) and social work consultation (n=162, 44%). The ED visit may provide an opportunity for older adults to be screened for fall risk. Our results show ED nurses can conduct the TUGT, a validated and time efficient screen, and place appropriate referrals based on assessment results. Identifying and intervening on high fall risk patients who visit the ED has the potential to improve the trajectory of functional decline in our elderly population.

A small number of studies have investigated breast cancer (BC) risk among women with a history of false-positive recall (FPR) in BC screening, but none of them has used time-to-event analysis while at the same time quantifying the effect of false-negative diagnostic assessment (FNDA). FNDA occurs when screening detects BC, but this BC is missed on diagnostic assessment (DA). As a result of FNDA, screenings that detected cancer are incorrectly classified as FPR. Our study linked data recorded in the Flemish BC screening program (women aged 50-69 years) to data from the national cancer registry. We used Cox proportional hazards models on a retrospective cohort of 298 738 women to assess the association between FPR and subsequent BC, while adjusting for potential confounders. The mean follow-up was 6.9 years. Compared with women without recall, women with a history of FPR were at an increased risk of developing BC [hazard ratio=2.10 (95% confidence interval: 1.92-2.31)]. However, 22% of BC after FPR was due to FNDA. The hazard ratio dropped to 1.69 (95% confidence interval: 1.52-1.87) when FNDA was excluded. Women with FPR have a subsequently increased BC risk compared with women without recall. The risk is higher for women who have a FPR BI-RADS 4 or 5 compared with FPR BI-RADS 3. There is room for improvement of diagnostic assessment: 41% of the excess risk is explained by FNDA after baseline screening.

Purpose. To evaluate the ability of various screening tests, both individually and in combination, to detect glaucoma in the general Latino population and high-risk subgroups. Methods. The Los Angeles Latino Eye Study is a population-based study of eye disease in Latinos 40 years of age and older. Participants (n = 6082) underwent Humphrey visual field testing (HVF), frequency doubling technology (FDT) perimetry, measurement of intraocular pressure (IOP) and central corneal thickness (CCT), and independent assessment of optic nerve vertical cup disc (C/D) ratio. Screening parameters were evaluated for three definitions of glaucoma based on optic disc, visual field, and a combination of both. Analyses were also conducted for high-risk subgroups (family history of glaucoma, diabetes mellitus, and age ≥65 years). Sensitivity, specificity, and receiver operating characteristic curves were calculated for those continuous parameters independently associated with glaucoma. Classification and regression tree (CART) analysis was used to develop a multivariate algorithm for glaucoma screening. Results. Preset cutoffs for screening parameters yielded a generally poor balance of sensitivity and specificity (sensitivity/specificity for IOP ≥21 mm Hg and C/D ≥0.8 was 0.24/0.97 and 0.60/0.98, respectively). Assessment of high-risk subgroups did not improve the sensitivity/specificity of individual screening parameters. A CART analysis using multiple screening parameters—C/D, HVF, and IOP—substantially improved the balance of sensitivity and specificity (sensitivity/specificity 0.92/0.92). Conclusions. No single screening parameter is useful for glaucoma screening. However, a combination of vertical C/D ratio, HVF, and IOP provides the best balance of sensitivity/specificity and is likely to provide the highest yield in glaucoma screening programs.

Introduction The Centers for Disease Control and Prevention is considering implementation of overseas medical screening of student-visa applicants to reduce the numbers of active tuberculosis cases entering the United States. Objective To evaluate the costs, cases averted, and cost-effectiveness of screening for, and treating, tuberculosis in United States-bound students from countries with varying tuberculosis prevalence. Methods Costs and benefits were evaluated from two perspectives, combined and United States only. The combined perspective totaled overseas and United States costs and benefits from a societal perspective. The United States only perspective was a domestic measure of costs and benefits. A decision tree was developed to determine the cost-effectiveness of tuberculosis screening and treatment from the combined perspective. Results From the United States only perspective, overseas screening programs of Chinese and Indian students would prevent the importation of 157 tuberculosis cases annually, and result in $2.7 million in savings. From the combined perspective, screening programs for Chinese students would cost more than $2.8 million annually and screening programs for Indian students nearly $440,000 annually. From the combined perspective, the incremental cost for each tuberculosis case averted by screening Chinese and Indian students was $22,187 and $15,063, respectively. Implementing screening programs for German students would prevent no cases in most years, and would result in increased costs both overseas and in the United States. The domestic costs would occur because public health departments would need to follow up on students identified overseas as having an elevated risk of tuberculosis. Conclusions Tuberculosis screening and treatment programs for students seeking long term visas to attend United States schools would reduce the number of tuberculosis cases imported. Implementing screening in high-incidence countries could save the United States millions of dollars annually; however there would be increased costs incurred overseas for students and their families.

This was a preliminary study on the prevalence of the HbS gene, associated with sickle cell disease, other hemoglobinopathies and G6PD deficiency of immigrant and non-immigrant population of Catalonia. A total of 3,189 blood samples from the Catalan Neonatal Screening Program for Metabolic Diseases (CNSPMD) including 1,620 from immigrant population were screened for haemoglobinopathies and G6PD deficiency. For screening of hemoglobinopathies the high performance liquid chromatography (HPLC) method was used and for the screening of G6PD deficiency, we used the fluorescent spot test as described by ICSH. 1. Hemoglobinopathies: in 47 samples from immigrant population 2 cases of sickle cell anemia (phenotypes FS and FSC) were detected as well as 45 cases of heterozygote carriers of different pathological hemoglobins (HbS, HbC, HbD and HbE). 2. G6PD deficiency: in 29 samples, 3 cases of G6PD deficiency belonging to local (non-immigrant) population of G6PD were detected. The incidence of sickle cell disease in the risk population of Catalonia is 1 case out of 810 samples. This value is significantly higher than that reported for any of the metabolic diseases included in the CNSPMD. Despite it is a preliminary study, the results obtained give further support to the convenience of incorporating a neonatal screening of hemoglobinopathies, at least in the risk population, to the official programs of newborn screening. Due to its feasibility and low cost, a similar criterion might be adopted for the neonatal screening of G6PD deficiency.

To estimate the incidence of prostate cancer among African-American men and Caribbean immigrants to the United States, to assess the applicability of large-scale prostate screening trials to a community screening program, and to recruit unscreened men. African-American and Caribbean-American men were targeted with a community-based prostate cancer screening program in Jamaica, New York. Serum prostate-specific antigen determination and digital rectal examination were used to determine abnormal findings. The incidence of an abnormal screening examination was used to project the incidence of prostate cancer, which was compared with that in other reported trials. The projected incidence of prostate cancer among African-Americans and Caribbean-Americans older than 50 years was 8% and 7%, respectively, similar to that reported in other trials of African-American men. The projected incidence of prostate cancer in Caribbean-American men aged 40 to 49 years was 1%, the same as the high rate reported among Caribbean men. As in other trials, a family history of prostate cancer and age were strong predictors of abnormal findings. Of the recruited men older than 50 years, 58% had never been screened compared with 42% nationally. Large population-based screening trials have identified ethnic groups at high risk of prostate cancer. This trial detected high rates of abnormal screening findings by targeting ethnicity. The incidence of an abnormal examination was high in Caribbean-American men younger than 50 years old. Finally, this trial successfully recruited underscreened men.

Sickle cell disease is an inherited disorder of the blood, and characterized by vasoocclusive crises (VOC), risks for pneumococcal infections and organ toxicities, is associated with morbidity and premature mortality. India, with a population of 1.2 billion individuals, is estimated to be home to over 50.0% of the world's patients with sickle cell disease. The β(S) gene [β6(A3)Glu→Val; HBB: c.20A>T] has the highest prevalence in three socio-economically disadvantaged ethnic categories: the Scheduled Castes (SC), the Scheduled Tribes (ST), and Other Backward Class (OBC) groups in India. The tradition of endogamy practiced by the ethnic groups in India provides the rationale for the screening of individual populations to better understand the distribution of the β(S) gene, guide counseling and awareness programs and aid development of public policy. We undertook a study to describe the prevalence of the β(S) gene in these ethnic groups in the district of Nagpur, Maharashtra in Central India. Through community screening and subsequent targeted screening of high risk individuals, 35,636 individuals were screened, of whom 5466 were found to have sickle cell trait and 1010 were identified with sickle cell disease. Community screening revealed a sickle cell trait prevalence of 13.0% in the SC, 12.0% in the ST and 3.4% in the OBC population. This study describes the prevalence of the β(S) gene within these groups in Central India determined by large scale community screening. This program has uncovered previously undiagnosed cases, provided detailed information to guide population-based disease counseling, prevention and comprehensive care programs.

Background Refugees are at an increased risk of chronic Hepatitis B Virus (HBV) infection because many of their countries of origin, as well as host countries, have intermediate-to-high prevalence rates. Refugees arriving to the US are also at risk of serious sequelae from chronic HBV infection because they are not routinely screened for the virus overseas or in domestic post-arrival exams, and may live in the US for years without awareness of their infection status. Methods A cohort of 26,548 refugees who arrived in Minnesota and Georgia during 2005–2010 was evaluated to determine the prevalence of chronic HBV infection. This prevalence information was then used in a cost-benefit analysis comparing two variations of a proposed overseas program to prevent or ameliorate the effects of HBV infection, titled ‘Screen, then vaccinate or initiate management’ (SVIM) and ‘Vaccinate only’ (VO). The analyses were performed in 2013. All values were converted to US 2012 dollars. Results The estimated six year period-prevalence of chronic HBV infection was 6.8% in the overall refugee population arriving to Minnesota and Georgia and 7.1% in those ≥ 6 years of age. The SVIM program variation was more cost beneficial than VO. While the up-front costs of SVIM were higher than VO ($154,084 vs. $73,758; n=58,538 refugees), the SVIM proposal displayed a positive net benefit, ranging from $24 million to $130 million after only 5 years since program initiation, depending on domestic post-arrival screening rates in the VO proposal. Conclusions Chronic HBV infection remains an important health problem in refugees resettling to the United States. An overseas screening policy for chronic HBV infection is more cost-beneficial than a ‘Vaccination only’ policy. The major benefit drivers for the screening policy are earlier medical management of chronic HBV infection and averted lost societal contributions from premature death. PMID:25595868

To explore prenatal practices related to aneuploidy screening, risk modification, and invasive diagnostic procedures across Canadian centres. We conducted a survey of members of the Canadian Association of Genetic Counsellors, the Canadian College of Medical Genetics, and the Canadian Society of Maternal Fetal Medicine, who provide direct counselling or management of prenatal patients in Canada. Eighty-two of 157 respondents indicated that their centre's definition of advanced maternal age was ≥ 35 years, with 33/157 respondents reporting an advanced maternal age definition of ≥ 40 years. The majority of respondents reported that prenatal serum screening for aneuploidy is provincially funded in their province or territory (121/147). The majority of respondents who reported that prenatal screening is not provincially funded (17/147) were from Quebec (14/17). Thirty-nine of 123 respondents reported that their centre defines increased nuchal translucency as ≥ 3.0 mm, whereas 49/123 reported a definition of ≥ 3.5 mm. Sixty-four of 150 respondents reported that the aneuploidy risk provided by serum screening is modified by a soft marker likelihood ratio, whereas 46/150 respondents reported that both age-related and serum screening risks are modified. Fifty-nine of 124 respondents reported that their centre will modify aneuploidy risk after a normal ultrasound; the most commonly cited negative likelihood ratio was 0.5. The most commonly reported procedure-related risk for chorionic villus sampling was 1/100 (123/147) and for amniocentesis was 1/200 (73/142). This study demonstrates inconsistencies in prenatal practices and access to screening programs across Canada. The information gained from this study will inform policy advisors developing prenatal practice guidelines at both the provincial and national levels.

Background The incidence of melanoma is increasing worldwide. Guidelines for clinical skin exam for improving early diagnosis of melanoma remain inconsistent, and current data on factors associated with regular skin screening on a population basis are limited. Methods We used self-reported data from 50,044 members of the California Twin Program, a population-based cohort of twins born in California between 1908 and 1982, to identify prevalence and determinants of recent clinical screening for skin cancer. Results Prevalence of skin examination was higher than national estimates, with 32% of respondents of all ages reporting ever having skin examination. Socio-demographic and constitutional risk factors including white race, educational attainment, marital status, and number of large moles were strongly associated with recent screening, as were individual and family history of skin cancer. Lower socioeconomic status, racial/ethnic minority status, and paradoxically, frequent UV-related risk behaviors in adulthood were associated with a lower likelihood of recent screening. Conclusions As the evidence concerning the efficacy of skin examination continues to evolve, attention should be paid to motivators and barriers of screening, particularly in high-risk subgroups where lack of screening may contribute to disparate rates of thicker melanomas and lower survival. Impact Our results demonstrate the need for prevention strategies targeted to specific at-risk groups to increase earlier detection leading to improved outcomes. PMID:25994738

In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancermore » Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical physicist in implementing Lung Cancer Screening protocols for CT, including utilizing resources such as the AAPM Protocols and the ACR Designated Lung Screening Center program.

Screening for colorectal cancer (CRC) is suboptimal, particularly for vulnerable populations. Effective intervention programs are needed to increase screening rates. We used a discrete choice experiment (DCE) to learn about how vulnerable individuals in North Carolina value different aspects of CRC screening programs. We enrolled English-speaking adults ages 50-75 at average risk of CRC from rural North Carolina communities with low rates of CRC screening, targeting those with public or no insurance and low incomes. Participants received basic information about CRC screening and potential program features, then completed a 16 task DCE and survey questions that examined preferences for four attributes of screening programs: testing options available; travel time required; money paid for screening or rewards for completing screening; and the portion of the cost of follow-up care paid out of pocket. We used Hierarchical Bayesian methods to calculate individual-level utilities for the 4 attributes' levels and individual-level attribute importance scores. For each individual, the attribute with the highest importance score was considered the most important attribute. Individual utilities were then aggregated to produce mean utilities for each attribute. We also compared DCE-based results with those from direct questions in a post-DCE survey. We enrolled 150 adults. Mean age was 57.8 (range 50-74); 55% were women; 76% White and 19% African-American; 87% annual household income under $30,000; and 51% were uninsured. Individuals preferred shorter travel; rewards or small copayments compared with large copayments; programs that included stool testing as an option; and greater coverage of follow-up costs. Follow-up cost coverage was most frequently found to be the most important attribute from the DCE (47%); followed by test reward/copayment (33%). From the survey, proportion of follow-up costs paid was most frequently cited as most important (42% of participants), followed by testing options (32%). There was moderate agreement (45%) in attribute importance between the DCE and the single question in the post-DCE survey. Screening test copayments and follow-up care coverage costs are important program characteristics in this vulnerable, rural population.

To validate a school-based amblyopia screening program model by comparing its outcomes to those of a state-of-the-art conventional ophthalmic clinic examination in a kindergarten population of children between the ages of 4 and 5 years. An amblyopia screening protocol, which consisted of visual acuity measurement using Lea charts, ocular alignment test, ocular motility assessment, and stereoacuity with TNO random-dot test, was performed at school in a pediatric 4- to 5-year-old population by qualified healthcare professionals. The outcomes were validated in a selected group by a conventional ophthalmologic examination performed in a fully equipped ophthalmologic center. The ophthalmologic evaluation was used to confirm whether or not children were correctly classified by the screening protocol. The sensitivity and specificity of the test model to detect amblyopia were established. A total of 18,587 4- to 5-year-old children were subjected to the amblyopia screening program during the 2010-2011 school year. A population of 100 children were selected for the ophthalmologic validation screening. A sensitivity of 89.3%, specificity of 93.1%, positive predictive value of 83.3%, negative predictive value of 95.7%, positive likelihood ratio of 12.86, and negative likelihood ratio of 0.12 was obtained for the amblyopia screening validation model. The amblyopia screening protocol model tested in this investigation shows high sensitivity and specificity in detecting high-risk cases of amblyopia compared to the standard ophthalmologic examination. This screening program may be highly relevant for amblyopia screening at schools.

A patient-level Markov decision model was used to simulate a virtual cohort of 500,000 women 40 years old and over, in relation to osteoporosis-related hip, clinical vertebral, and wrist bone fractures events. Sixteen different screening options of three main scenario groups were compared: (1) the status quo (no specific national prevention program); (2) a universal primary prevention program; and (3) a universal screening and treatment program based on the 10-year absolute risk of fracture. The outcomes measured were total directs costs from the perspective of the public health care system, number of fractures, and quality-adjusted life-years (QALYs). Results show that an option consisting of a program promoting physical activity and treatment if a fracture occurs is the most cost-effective (CE) (cost/fracture averted) alternative and also the only cost saving one, especially for women 40 to 64 years old. In women who are 65 years and over, bone mineral density (BMD)-based screening and treatment based on the 10-year absolute fracture risk calculated using a Canadian Association of Radiologists and Osteoporosis Canada (CAROC) tool is the best next alternative. In terms of cost-utility (CU), results were similar. For women less than 65 years old, a program promoting physical activity emerged as cost-saving but BMD-based screening with pharmacological treatment also emerged as an interesting alternative. In conclusion, a program promoting physical activity is the most CE and CU option for women 40 to 64 years old. BMD screening and pharmacological treatment might be considered a reasonable alternative for women 65 years old and over because at a healthcare capacity of $50,000 Canadian dollars ($CAD) for each additional fracture averted or for one QALY gained its probabilities of cost-effectiveness compared to the program promoting physical activity are 63% and 75%, respectively, which could be considered socially acceptable. Consideration of the indirect costs could change these findings. Copyright © 2013 American Society for Bone and Mineral Research.

Posttraumatic stress disorder (PTSD) is a psychiatric disorder that affects 7-8% of the general U.S. population at some point during their lifetime; however, the prevalence is much higher among certain subgroups, including active duty military personnel and veterans. In this article, we review the empirical literature on the epidemiology and screening of PTSD in military and veteran populations, including the availability of sensitive and reliable screening tools. Although estimates vary across studies, evidence suggests that the prevalence of PTSD in deployed U.S. military personnel may be as high as 14-16%. Prior studies have identified trauma characteristics and pre- and posttrauma factors that increase risk of PTSD among veterans and military personnel. This information may help to inform prevention and screening efforts, as screening programs could be targeted to high-risk populations. Large-scale screening efforts have recently been implemented by the U.S. Departments of Defense and Veterans Affairs. Given the prevalence and potential consequences of PTSD among veterans and active duty military personnel, development and continued evaluation of effective screening methods is an important public health need.

Targeted donor screening for strongyloidiasis performed at the time of organ procurement can prevent this life-threatening donor-derived infection. The Association of Organ Procurement Organizations surveyed members to determine the number of US organ procurement organizations (OPOs) performing donor screening for Strongyloides infection and their screening practices. All 58 OPOs responded to the survey. Only 6 (10%) currently screen donors for strongyloidiasis; most OPOs started 6-36 months before the survey and one started 6 years prior. All used risk-based criteria to determine which donors to screen, though the criteria varied among OPOs. A median of 56 donors have been screened at each OPO since initiating their screening programs, with a median of 2 infected donors (range 0-13) identified. Overall, 53 organs have been transplanted from 22 infected donors, including hearts, lungs, kidneys, and livers. Of 52 OPOs not currently screening, 20 had considered screening and one plans to start screening in the near future. Of those considering risk-based screening, most had not decided on the criteria. Uncertainty about the benefits of and guidelines for screening and misconceptions about the interpretation of test results were concerns shared by non-screening OPOs. Continued education and advocacy on the importance of targeted donor screening are needed. Published 2018. This article is a U.S. Government work and is in the public domain in the USA.

Background Men with a family history of prostate cancer and African American men are at high risk for prostate cancer and in need of personalized risk estimates to inform screening decisions. This study evaluated genetic variants in genes encoding microRNA (miRNA) binding sites for informing of time to prostate cancer diagnosis among ethnically-diverse, high-risk men undergoing prostate cancer screening. Methods The Prostate Cancer Risk Assessment Program (PRAP) is a longitudinal screening program for high-risk men. Eligibility includes men ages 35-69 with a family history of prostate cancer or African descent. Participants with ≥ 1 follow-up visit were included in the analyses (n=477). Genetic variants in regions encoding miRNA binding sites in four target genes (ALOX15, IL-16, IL-18, and RAF1) previously implicated in prostate cancer development were evaluated. Genotyping methods included Taqman® SNP Genotyping Assay (Applied Biosystems) or pyrosequencing. Cox models were used to assess time to prostate cancer diagnosis by risk genotype. Results Among 256 African Americans with ≥ one follow-up visit, the TT genotype at rs1131445 in IL-16 was significantly associated with earlier time to prostate cancer diagnosis vs. the CC/CT genotypes (p=0.013), with a suggestive association after correction for false-discovery (p=0.065). Hazard ratio after controlling for age and PSA for TT vs. CC/CT among African Americans was 3.0 (95% CI 1.26-7.12). No association to time to diagnosis was detected among Caucasians by IL-16 genotype. No association to time to prostate cancer diagnosis was found for the other miRNA target genotypes. Conclusions Genetic variation in IL-16 encoding miRNA target site may be informative of time to prostate cancer diagnosis among African American men enrolled in prostate cancer risk assessment, which may inform individualized prostate cancer screening strategies in the future.

We analysed all female breast cancer (BC) cases in Tyrol/Austria regarding the shift in cancer characteristics, especially the shift in advanced BC, for the group exposed to screening as compared to the group unexposed to screening. The analysis was based on all BC cases diagnosed in women aged 40-69 years, resident in Tyrol, and diagnosed between 2009 and 2013. The data were linked to the Tyrolean mammography screening programme database to classify BC cases as "exposed to screening" or "unexposed to screening". Age-adjusted relative risks (RR) were estimated by relating the exposed to the unexposed group. In a total of about 145,000 women aged 40-69 years living in Tyrol during the study period, 1475 invasive BC cases were registered. We estimated an age-adjusted relative risk (RR) for tumour size ≥ 21 mm of 0.72 (95% confidence interval (CI) 0.60 to 0.86), for metastatic BC of 0.27 (95% CI 0.17 to 0.46) and for advanced BC of 0.83 (95% CI 0.71 to 0.96), each comparing those exposed to those unexposed to screening, respectively. In our population-based registry analysis we observed that participation in the mammography screening programme in Tyrol is associated with a 28% decrease in risk for BC cases with tumour size ≥ 21 mm and a 17% decrease in risk for advanced BC. We therefore expect the Tyrolean mammography programme to show a reduction in BC mortality. Copyright © 2017 Elsevier Ltd. All rights reserved.

Patients with chronic obstructive pulmonary disease (COPD) are at risk for lung cancer; the diseases have common etiologies, including cigarette smoking. We aimed to clarify the effectiveness of COPD detection using a regional mass-screening program for lung cancer. A total of 7,067 residents of Togane, Chiba, Japan received lung cancer screening between May and July, 2011. We defined four groups of possible COPD candidates: group A (n=358), positive smoking history, positive chronic respiratory symptoms; group B (n=766), positive smoking history, positive lifestyle-related disease; group C (n=75), passive smoking history, positive chronic respiratory symptoms; and group D (n=301), passive smoking history, positive lifestyle-related disease. Candidates underwent on-site pulmonary function testing (PFT). The criteria for COPD candidates were fulfilled in 1,686 of 7,067 individuals (23.9%); 1,500 participants underwent PFT (89%), and 171 (11.4%) were diagnosed with COPD. The overall COPD detection rate was 2.4%. The frequency of COPD was significantly higher in groups A and B than in groups C and D (P=0.048); however, the distribution of COPD grades was similar among the groups (P=0.372). Multiple logistic regression analysis identified male sex, age 60 years or greater, and positive smoking history as risk factors for COPD. COPD screening using a community-based lung cancer-screening program may be effective for disease detection. Individuals who are 60 years of age or older with a positive smoking history should undergo PFT to detect COPD.

Newborn screening (NBS) programs aim to identify affected infants before the onset of treatable disorders. Historically, benefits to the family and society were considered secondary to this clinical benefit; yet, recent discourse defending expanded NBS has argued that screening can in part be justified by secondary benefits, such as learning reproductive risk information to support family planning (‘reproductive benefit'). Despite increased attention to these secondary benefits of NBS, stakeholders' values remain unknown. We report a mixed methods study that included an examination of providers' views toward the pursuit of reproductive risk information through NBS, using sickle cell disorder carrier status as an example. We surveyed a stratified random sample of 1615 providers in Ontario, and interviewed 42 providers across 7 disciplines. A majority endorsed the identification of reproductive risks as a goal of NBS (74–77%). Providers' dominant rationale was that knowledge of carrier status is an important and inherent benefit of NBS as it allows people to make reproductive choices, which is consistent with the goals of disease prevention. However, some challenged its appropriateness, questioning its logic, timing and impact on disease prevention. Others were sensitive to intruding on individuals' choices or children's independent rights. While the dominant view is consistent with discourse defending expanded NBS, it deviates from the traditional screening principles that underpin most public health interventions. Broader discussion of the balance between benefits to screened individuals and those to families and societies, in the context of public health programs, is needed. PMID:22071888

Families at risk of poor parenting: a model for service delivery, assessment, and intervention.

The At Risk Parent Child Program is a multidisciplinary network agency designed for the secondary prevention of poor parenting and the extremes of child abuse and neglect. This model system of service delivery emphasizes (1) the coordination of existing community resources to access a target population of families at risk of parenting problems, (2) the provision of multiple special services in a neutral location (ambulatory pediatric clinic), and (3) the importance of intensive individual contact with a clinical professional who serves as primary therapist, social advocate and service coordinator for client families. Identification and assessment of families is best done during prenatal and perinatal periods. Both formal and informal procedures for screening for risk factors are described, and a simple set of at risk criteria for use by hospital nursing staff is provided. Preventive intervention strategies include special medical, psychological, social and developmental services, offered in an inpatient; outpatient, or in-home setting. Matching family needs to modality and setting of treatment is a major program concern. All direct services to at risk families are supplied by professionals employed within existing local agencies (hospital, public health department, state guidance center, and medical school pediatric clinic). Multiple agency involvement allows a broad-based screening capacity which allows thousands of families routine access to program services. The administrative center of the network stands as an independent, community-funded core which coordinates and monitors direct clinical services, and provides local political advocacy for families at risk of parenting problems.

On December 1, 2015, the Japanese government launched the Stress Check Program, a new occupational health policy to screen employees for high psychosocial stress in the workplace. As only weak evidence exists for the effectiveness of the program, we sought to estimate the risk of stress-associated long-term sickness absence as defined in the program manual. Participants were 7356 male and 7362 female employees in a financial service company who completed the Brief Job Stress Questionnaire (BJSQ). We followed them for 1 year and used company records to identify employees with sickness absence of 1 month or longer. We defined high-risk employees using the BJSQ and criteria recommended by the program manual. We used the Cox proportional regression model to evaluate the prospective association between stress and long-term sickness absence. During the follow-up period, we identified 34 male and 35 female employees who took long-term sickness absence. After adjustment for age, length of service, job type, position, and post-examination interview, hazard ratios (95% confidence intervals) for incident long-term sickness absence in high-stress employees were 6.59 (3.04-14.25) for men and 2.77 (1.32-5.83) for women. The corresponding population attributable risks for high stress were 23.8% (10.3-42.6) for men and 21.0% (4.6-42.1) for women. During the 1-year follow-up, employees identified as high stress (as defined by the Stress Check Program manual) had significantly elevated risks for long-term sickness absence.

A tailored intervention to promote uptake of retinal screening among young adults with type 2 diabetes - an intervention mapping approach.

Young adults (18-39 years) with type 2 diabetes are at risk of early development and rapid progression of diabetic retinopathy, a leading cause of vision loss and blindness in working-age adults. Retinal screening is key to the early detection of diabetic retinopathy, with risk of vision loss significantly reduced by timely treatment thereafter. Despite this, retinal screening rates are low among this at-risk group. The objective of this study was to develop a theoretically-grounded, evidence-based retinal screening promotion leaflet, tailored to young adults with type 2 diabetes. Utilising the six steps of Intervention Mapping, our multidisciplinary planning team conducted a mixed-methods needs assessment (Step 1); identified modifiable behavioural determinants of screening behaviour and constructed a matrix of change objectives (Step 2); designed, reviewed and debriefed leaflet content with stakeholders (Steps 3 and 4); and developed program implementation and evaluation plans (Steps 5 and 6). Step 1 included in-depth qualitative interviews (N = 10) and an online survey that recruited a nationally-representative sample (N = 227), both informed by literature review. The needs assessment highlighted the crucial roles of knowledge (about diabetic retinopathy and screening), perception of personal risk, awareness of the approval of significant others and engagement with healthcare team, on retinal screening intentions and uptake. In Step 2, we selected five modifiable behavioural determinants to be targeted: knowledge, attitudes, normative beliefs, intention, and behavioural skills. In Steps 3 and 4, the "Who is looking after your eyes?" leaflet was developed, containing persuasive messages targeting each determinant and utilising engaging, cohort-appropriate imagery. In Steps 5 and 6, we planned Statewide implementation and designed a randomised controlled trial to evaluate the leaflet. This research provides an example of a systematic, evidence-based approach to the development of a simple health intervention designed to promote uptake of screening in accordance with national guidelines. The methods and findings illustrate how Intervention Mapping can be employed to develop tailored retinal screening promotion materials for specific priority populations. This paper has implications for future program planners and is intended to assist those wishing to use Intervention Mapping to create similar theoretically-driven, tailored resources.

Polycystic ovary syndrome: a major unrecognized cardiovascular risk factor in women.

PubMed

Alexander, Carolyn J; Tangchitnob, Edward P; Lepor, Norman E

2009-01-01

The prevalence of polycystic ovary syndrome (PCOS) is estimated to be nearly 10% among reproductive-age women. PCOS may represent the largest underappreciated segment of the female population at risk of cardiovascular disease. Clinicians providing care to women of childbearing age must recognize the presenting clues, including irregular menses, hirsutism, alopecia, hyperandrogenemia, and obesity. The pathophysiology of PCOS is complex, involving the hypothalamus-pituitary-ovarian axis, ovarian theca cell hyperplasia, hyperinsulinemia, and a multitude of other cytokine- and adipocyte-driven factors. Cardiac risk factors associated with PCOS have public health implications and should drive early screening and intervention measures. There are no consensus guidelines regarding screening for cardiovascular disease in patients with PCOS. Fasting lipid profiles and glucose examinations should be performed regularly. Carotid intimal medial thickness examinations should begin at age 30 years, and coronary calcium screening should begin at age 45 years. Treatment of the associated cardiovascular risk factors, including insulin resistance, hypertension, and dyslipidemia, should be incorporated into the routine PCOS patient wellness care program.

Employee wellness programs (EWPs) have been used to implement worksite-based cancer prevention and control interventions. However, little is known about whether these programs result in improved adherence to cancer screening guidelines or how participants' characteristics affect subsequent screening. This study was conducted to describe cancer screening behaviors among participants in a state EWP and identify factors associated with screening adherence among those who were initially nonadherent. We identified employees and their dependents who completed health risk assessments (HRAs) as part of the Kansas state EWP in both 2008 and 2009. We examined baseline rates of adherence to cancer screening guidelines in 2008 and factors associated with adherence in 2009 among participants who were initially nonadherent. Of 53,095 eligible participants, 13,222 (25%) participated in the EWP in 2008 and 6,205 (12%) participated in both years. Among the multiyear participants, adherence was high at baseline to screening for breast (92.5%), cervical (91.8%), and colorectal cancer (72.7%). Of participants who were initially nonadherent in 2008, 52.4%, 41.3%, and 33.5%, respectively, became adherent in the following year to breast, cervical, and colorectal cancer screening. Suburban/urban residence and more frequent doctor visits predicted adherence to breast and colorectal cancer screening guidelines. The effectiveness of EWPs for increasing cancer screening is limited by low HRA participation rates, high rates of adherence to screening at baseline, and failure of nonadherent participants to get screening. Improving overall adherence to cancer screening guidelines among employees will require efforts to increase HRA participation, stronger interventions for nonadherent participants, and better access to screening for rural employees.

Results Of 53,095 eligible participants, 13,222 (25%) participated in the EWP in 2008 and 6,205 (12%) participated in both years. Among the multiyear participants, adherence was high at baseline to screening for breast (92.5%), cervical (91.8%), and colorectal cancer (72.7%). Of participants who were initially nonadherent in 2008, 52.4%, 41.3%, and 33.5%, respectively, became adherent in the following year to breast, cervical, and colorectal cancer screening. Suburban/urban residence and more frequent doctor visits predicted adherence to breast and colorectal cancer screening guidelines. Conclusion The effectiveness of EWPs for increasing cancer screening is limited by low HRA participation rates, high rates of adherence to screening at baseline, and failure of nonadherent participants to get screening. Improving overall adherence to cancer screening guidelines among employees will require efforts to increase HRA participation, stronger interventions for nonadherent participants, and better access to screening for rural employees.

Despite the significance of cervical cancer screening, motivating more women to participate remains a challenge in resource-limited settings. In this study, we tested the protection motivation theory (PMT) in predicting screening intentions. Participants were women from Wufeng, a typical rural county in China. Participants (n = 3000) with no cervical cancer history were recruited from 10 randomly selected villages. As mediating variables, 6 PMT constructs (Perceived Risk, Fear Arousal, Perceived Severity, Response Efficacy, Response Cost, and Self-Efficacy) were measured using the standardized questionnaire. Structural equation modeling (SEM) method was employed to test PMT-based prediction models. Of the total sample, 57.77% believed that regular screening may reduce cervical cancer risk, and 45.26% agreed that women should be screened regularly. Our data fit the PMT model well (GFI = 0.95, AGFI = 0.93, CFI = 0.90, RMSEA = 0.06, SRMR = 0.04, Chi-square/df = 2.47). Knowledge of screening was directly and positively associated with screening intention. Age, annual income, and awareness of and prior experience with screening were significantly associated with screening intention by enhancing cervical cancer risk perception and by reducing response cost (P<0.05 for both). PMT can be used as guidance to investigate cervical cancer screening intentions among rural women in China with focus on cancer knowledge, some demographic factors, and awareness of and previous experience with screening. These findings, if verified with longitudinal data, can be used for intervention program development. Copyright © 2017 John Wiley & Sons, Ltd.

Our trauma division implemented a screening, brief intervention, and referral to treatment (SBIRT) program in 2009 and has maintained more than 92% screening rate for all inpatient admissions since inception. Brief interventions are proven to be more likely to effect and reinforce change if a follow-up contact is made with patients. This led to discussion regarding whether identified patients were more likely to follow up with our SBIRT wellness specialist using motivational interviewing or with our partners, exercise physiology, who use traditional interviewing techniques. We retrospectively reviewed more than 3,000 inpatient admissions in which screening for at-risk alcohol use were positive. Fifty-one percent of identified patients were referred for wellness specialist consultation with a follow-up rate of 52% compared with a follow-up rate of only 21% in the exercise physiology group. Motivational interviewing is more effective in encouraging at-risk alcohol users to participate in follow-up care.

Obstructive sleep apnea among commercial motor vehicle drivers: using evidence-based practice to identify risk factors.

Olszewski, Kimberly; Wolf, Debra

2013-11-01

Commercial motor vehicle driving is a hazardous occupation, having the third highest fatality rate among common U.S. jobs. Among the estimated 14 million U.S. commercial motor vehicle drivers, the prevalence of obstructive sleep apnea is reported to be 17% to 28%. Despite the identified increased prevalence of obstructive sleep apnea among commercial motor vehicle drivers, federal law does not require that they be screened for obstructive sleep apnea. This article presents an evidence-based practice change project; the authors developed, implemented, and evaluated a screening program to identify commercial motor vehicle drivers' risk for obstructive sleep apnea during commercial driver medical examinations. The results of this practice change indicated screening for obstructive sleep apnea during the commercial driver medical examination led to improved identification of obstructive sleep apnea risk among commercial motor vehicle drivers and should be a clinical standard in occupational health clinics.

To reduce mortality, women with a family history of breast cancer are often screened with mammography before age 50 years. Additional magnetic resonance imaging (MRI) improves sensitivity and is cost-effective for BRCA1/2 mutation carriers. However, for women with a family history without a proven mutation, cost-effectiveness is unclear. We evaluated data of the largest prospective MRI screening study (MRISC). Between 1999 and 2007, 1597 women (8370 woman-years at risk) aged 25 to 70 years with an estimated cumulative lifetime risk of 15% to 50% for breast cancer were screened with clinical breast examination every 6 months and with annual mammography and MRI. We calculated the cost per detected and treated breast cancer. After incorporating MRISC data into a microsimulation screening analysis model (MISCAN), different schemes were evaluated, and cost per life-year gained (LYG) was estimated in comparison with the Dutch nationwide breast cancer screening program (biennial mammography from age 50 to 75 years). All statistical tests were two-sided. Forty-seven breast cancers (9 ductal carcinoma in situ) were detected. Screening with additional MRI costs $123 672 (€93 639) per detected breast cancer. In increasing age-cohorts, costs per detected and treated breast cancer decreased, but, unexpectedly, the percentage of MRI-only detected cancers increased. Screening under the MRISC-scheme from age 35 to 50 years was estimated to reduce breast cancer mortality by 25% at $134 932 (€102 164) per LYG (3.5% discounting) compared with 17% mortality reduction at $54 665 (€41 390) per LYG with mammography only. Screening with MRI may improve survival for women with familial risk for breast cancer but is expensive, especially in the youngest age categories.

To examine women's preferences for characteristics of chlamydia screening. Chlamydia trachomatis is the most common curable sexually transmitted disease. To design effective screening programs, it is important to fully capture the benefits of screening to patients. Thus, the value of experience factors must be considered alongside health outcomes. A self-complete discrete choice experiment questionnaire was administered to women attending a family planning clinic. Chlamydia screening was described by five characteristics: location of screening; type of screening test; cost of screening test; risk of developing pelvic inflammatory disease if chlamydia is untreated; and support provided when receiving results. One hundred twenty-six women completed the questionnaire. Respondents valued characteristics of the care experience. Screening was valued at 15 pound; less invasive screening tests increase willingness to pay by 7 pound, and more invasive tests reduce willingness to pay by 3.50 pound. The most preferred screening location was the family planning clinic, valued at 5 pound. The support of a trained health-care professional when receiving results was valued at 4 pound. Respondents under 25 years and those in a casual relationship were less likely to be screened. Women valued experience factors in the provision of chlamydia screening. To correctly value these screening programs and to predict uptake, cost-effectiveness studies should take such values into account. Failure to do this may result in incorrect policy recommendations.

A screening program for lung cancer requires more empirical evidence. Based on the experience of the National Lung Screening Trial (NLST), we developed a method to adjust lead-time bias and quality-of-life changes for estimating the cost-effectiveness of implementing computed tomography (CT) screening in Taiwan. The target population was high-risk (≥30 pack-years) smokers between 55 and 75 years of age. From a nation-wide, 13-year follow-up cohort, we estimated quality-adjusted life expectancy (QALE), loss-of-QALE, and lifetime healthcare expenditures per case of lung cancer stratified by pathology and stage. Cumulative stage distributions for CT-screening and no-screening were assumed equal to those for CT-screening and radiography-screening in the NLST to estimate the savings of loss-of-QALE and additional costs of lifetime healthcare expenditures after CT screening. Costs attributable to screen-negative subjects, false-positive cases and radiation-induced lung cancer were included to obtain the incremental cost-effectiveness ratio from the public payer's perspective. The incremental costs were US$22,755 per person. After dividing this by savings of loss-of-QALE (1.16 quality-adjusted life year (QALY)), the incremental cost-effectiveness ratio was US$19,683 per QALY. This ratio would fall to US$10,947 per QALY if the stage distribution for CT-screening was the same as that of screen-detected cancers in the NELSON trial. Low-dose CT screening for lung cancer among high-risk smokers would be cost-effective in Taiwan. As only about 5% of our women are smokers, future research is necessary to identify the high-risk groups among non-smokers and increase the coverage. Copyright © 2017 The Author(s).

Recent research has identified high hepatitis C virus (HCV) prevalence among older U.S. residents who contracted HCV decades ago and may no longer be recognized as high risk. We assessed the cost-effectiveness of screening 100% of U.S. residents born 1946-1970 over 5 years (birth-cohort screening), compared with current risk-based screening, by projecting costs and outcomes of screening over the remaining lifetime of this birth cohort. A Markov model of the natural history of HCV was developed using data synthesized from surveillance data, published literature, expert opinion, and other secondary sources. We assumed eligible patients were treated with pegylated interferon plus ribavirin, with genotype 1 patients receiving a direct-acting antiviral in combination. The target population is U.S. residents born 1946-1970 with no previous HCV diagnosis. Among the estimated 102 million (1.6 million chronically HCV infected) eligible for screening, birth-cohort screening leads to 84,000 fewer cases of decompensated cirrhosis, 46,000 fewer cases of hepatocellular carcinoma, 10,000 fewer liver transplants, and 78,000 fewer HCV-related deaths. Birth-cohort screening leads to higher overall costs than risk-based screening ($80.4 billion versus $53.7 billion), but yields lower costs related to advanced liver disease ($31.2 billion versus $39.8 billion); birth-cohort screening produces an incremental cost-effectiveness ratio (ICER) of $37,700 per quality-adjusted life year gained versus risk-based screening. Sensitivity analyses showed that reducing the time horizon during which health and economic consequences are evaluated increases the ICER; similarly, decreasing the treatment rates and efficacy increases the ICER. Model results were relatively insensitive to other inputs. Birth-cohort screening for HCV is likely to provide important health benefits by reducing lifetime cases of advanced liver disease and HCV-related deaths and is cost-effective at conventional willingness-to-pay thresholds.

HPV vaccination programs have not been shown to be cost-effective in countries with comprehensive Pap screening and surgery.

PubMed

Wilyman, Judy

2013-06-12

Pap screening combined with loop electrosurgical excision procedures (LEEP) is almost 100% effective in preventing cervical cancer mortality yet many countries with these procedures have now implemented broad HPV vaccination programs. HPV vaccines have not been demonstrated to be more effective or safer than Pap screening in the prevention of cervical cancer and Pap screening will still be required even in vaccinated women. The HPV vaccine costs Au$450 per person and it does not protect against ~30% of cancer. This investigation analyses the cost-effectiveness of using the HPV vaccine in countries where Pap screening and surgical procedures have already reduced cervical cancer mortality to very low rates. Cost-effectiveness of vaccination programs is being determined by mathematical models which are founded on many assumptions. It is necessary to examine the rigor of these assumptions to be certain of the health benefits that are predicted. In 2002 scientists concluded that HPV 16 and 18 were the central and independent cause of most cervical cancer. This conclusion was based on molecular technology. If HPV 16 and 18 infections are the central and independent cause of most cervical cancer then the incidence of HPV 16 and 18 should vary with the incidence and mortality of cervical cancer worldwide. This correlation does not exist. It is also observed that the majority of HPV 16/18 infections do not lead to cervical cancer. This indicates that other etiological or 'risk' factors are necessary for persistent HPV infection to progress to cancer. The benefits of HPV vaccines have been determined by using pre-cancerous lesions in young women as a surrogate for cervical cancer. This surrogate is found to be inadequate as an end-point for cervical cancer. Clinical trials have only provided speculative benefits for the efficacy of HPV vaccines against cancer and the long-term risks of the vaccine have not been established. Pap screening will still be required in vaccinated women hence HPV vaccination programs are not cost-effective, and may do more harm than good, in countries where regular Pap screening and surgery has already reduced the burden of this disease.

The literature reports great variation in the knowledge levels and application of the recent changes of cervical cancer screening guidelines into clinical practice. Evidence-based screening guidelines for the prevention and early detection of cervical cancer offers healthcare providers the opportunity to improve practice patterns among female adolescents by decreasing psychological distress as well as reducing healthcare costs and morbidities associated with over-screening. The purpose of this pilot intervention study was to determine the effects of a Web-based continuing education unit (CEU) program on advanced practice nurses' (APNs) knowledge of current cervical cancer screening evidence-based recommendations and their application in practice. This paper presents a process improvement project as an example of a way to disseminate updated evidence-based practice guidelines among busy healthcare providers. This Web-based CEU program was developed, piloted, and evaluated specifically for APNs. The program addressed their knowledge level of cervical cancer and its relationship with high-risk human papillomavirus. It also addressed the new cervical cancer screening guidelines and the application of those guidelines into clinical practice. Results of the study indicated that knowledge gaps exist among APNs about cervical cancer screening in adolescents. However, when provided with a CEU educational intervention, APNs' knowledge levels increased and their self-reported clinical practice behaviors changed in accordance with the new cervical cancer screening guidelines. Providing convenient and readily accessible up-to-date electronic content that provides CEU enhances the adoption of clinical practice guidelines, thereby decreasing the potential of the morbidities associated with over-screening for cervical cancer in adolescents and young women. © 2014 Sigma Theta Tau International.

Adults on probation are at greater risk of both using substances and having a mental disorder compared to the general population. Several theories explain the relationship between substance use and poor mental health. However, the interaction between substance use, mental health, and substance-related consequences is not well understood. A better understanding of this relationship may help treatment programs become more responsive to people with serious mental illness (SMI). The current study used interview data from 313 adults on probation who reported recent substance use. We examined associations between SMI risk, substance use, and substance use consequences. A substantial proportion of the sample (37.5%) screened at risk of having a SMI. Adjusting for type and amount of substance use, those who screened at risk of having a SMI reported more negative substance use consequences. Significant interaction effects were observed between use of alcohol or opiates and SMI risk. Alcohol use was associated with more negative substance use consequences among those at risk of SMI, while opiate use was associated with more consequences among those not at risk. Programs are sorely needed to identify and treat adults with comorbid substance use and mental health symptoms, particularly for adults in the justice system. Clinicians should carefully consider how mental health may interact with substance use to exacerbate consequences.

Choosing the optimal method in programmatic colorectal cancer screening: current evidence and controversies

PubMed Central

2015-01-01

Colorectal cancer (CRC) is an important health problem all over the world, being the third most common cancer and the second leading cause of cancer-related death in Western countries. The most important strategy for CRC prevention is screening (i.e. secondary prevention). Since it is widely accepted that adenomas and serrated polyps are the precursors of the vast majority of CRC, early detection and removal of these lesions is associated with a reduction of CRC incidence and, consequently, mortality. Moreover, cancers detected by screening are usually diagnosed at early stages and, therefore, curable by endoscopic or surgical procedures. This review will be address CRC screening strategies in average-risk population, which is defined by those individuals, men and women, 50 years of age or older, without any additional personal or familial predisposing risk factor. In order to maximize the impact of screening and ensure high coverage and equity of access, only organized screening programs (i.e. programmatic screening) should be implemented, as opposed to case-finding or opportunistic screening. For that reason and considering that the optimal approach for colorectal screening may differ depending on the scenario, this review will be focused on the advantages and limitations of each screening strategy in an organized setting.

SUMMARY In the wake of new recommendations to offer HIV screening to everyone aged 13–64 years and to start all people living with HIV/AIDS on highly active antiretroviral therapy (HAART) regardless of CD4 count, the need to generate widespread, scalable HIV screening programs is greater than ever. Nearly 50,000 new HIV infections occur in the United States each year, and the Centers for Disease Control and Prevention estimates that approximately half of these new infections are transmitted by individuals who are unaware of their HIV serostatus. Numerous barriers to screening exist, including the lack of primary care for many at-risk patients, expense of screening in traditional settings, and need for repeat testing in high-risk populations. With their relative accessibility and affordability, community pharmacies and retail clinics within those pharmacies are practical and appealing venues for expanded HIV screening. For widespread pharmacy-based testing to become a reality, policymakers and corporate pharmacy leadership would need to develop innovative solutions to the existing time pressures of pharmacists’ behind-the-counter functions and absence of reimbursement for direct patient care services. Pharmacists nationwide should also receive training to assist with risk reduction counseling and linkage to care for customers purchasing the new over-the-counter HIV test. PMID:24684638

To evaluate the impact of a tuberculosis (TB) educational intervention (EI) on change in adolescent student knowledge and participation in a TB prevention program. From 2/2013-5/2015, students from 2 high schools in Houston, TX participated. The 25-min EI discussed TB bacteriology, epidemiology, symptoms, and indications for TB testing/treatment. Students completed pre- and post-quizzes. Immediately after the EI, students were invited to participate in voluntary TB risk-factor screening, testing and treatment. At 6 months, focus groups were conducted. 895 students attended the EI. 827 students (92%) completed the EI quizzes. Knowledge improved by 12% (pre: 70%; post: 82%, p<0.001); 78% shared their TB knowledge. Following the EI, 671/827 (81%) enrolled in a TB prevention program. Focus groups indicated that the EI stimulated student learning about TB and increased their willingness to participate. A brief, one-time, TB EI is an effective method to encourage adolescents to learn about TB and motivate their uptake of TB risk-factor screening, testing and treatment. Similar EIs should accompany TB prevention programs targeting adolescents. The study's procedures could be considered for incorporation into school-based TB prevention programs to improve the identification, testing and treatment of adolescents at risk for TB.

Serum alpha-fetoprotein (AFP) measurement is commonly included in a health check-up program in Korea. However, its benefits remain uncertain. We analyzed whether AFP measurement should be included in a general health check-up program to screen for hepatocellular carcinoma (HCC). A total of 36,552 adults aged 18 years or older-who participated in a routine health examination including AFP determination between January 2009 and December 2009 at the Health Promotion Center, Samsung Medical Center, South Korea-were analyzed. High risk of HCC was defined as positivity for hepatitis B surface antigen, anti-hepatitis C virus antibody or having liver cirrhosis. AFP level >10 ng/mL was observed in 27 participants (0.1%) and primary liver cancer was diagnosed in 9 patients (6 HCC and 3 cholangiocarcinoma). Among 1,619 participants with high risk factors of HCC, AFP level >10 ng/mL was observed in 16 participants, of which, 4 diagnoses were made. Sensitivity, specificity, positive predictive value, and negative predictive value of AFP for HCC was 0.66, 0.99, 0.25 and 0.99, respectively, for high risk participants. Among 34,933 participants without risk factors for HCC, 11 patients (<0.1%) showed elevated AFP levels above 10 ng/mL, and no case was diagnosed with primary liver cancer during a median follow-up period of 36 months (range: 0-48 months). AFP elevation was rare in participants without risk factors for HCC, and was unable to screen for HCC in this population. We discourage routine AFP measurements for asymptomatic adults without risk factors of HCC.

Cervical carcinoma in the European Union: an update on disease burden, screening program state of activation, and coverage as of March 2014.

Cervical cancer (CC) is defined as a disease of disparity. This is due to marked differences in CC incidence and mortality between developed and developing countries. As a continent, Europe is no exception. This study examines the state of activation of CC screening in the European Union as of March 2014, reviews CC incidence and mortality data, and highlights the initiatives adopted to extend program coverage to nonresponders. The present study is based on the most recent data available from PubMed-indexed journals, the Web sites of the health ministries of each member state, and the Web sites of national cancer observatories; failing these sources, information was sought in scientific journals published in the local language. In 2003, the European Council recommended that priority be given to organized screening program activation. Nonetheless, a number of European Union member states still lack population-based organized screening programs, and few have implemented programs directed at disadvantaged populations. Several investigations have demonstrated that the women at higher CC risk are unscreened and underscreened ones. Since then, several member states have made significant efforts to set up effective prevention programs by adopting international quality standards and centralizing screening organization and result evaluation. Several developed countries and some new central-eastern European member states have poorly organized prevention programs that result in poor women's health. Diagnosis of CC is emotionally traumatic, but it is highly preventable. When CC is found early, it is highly treatable and associated with long survival and good quality of life.

Background & Aims The risk of serious complications after colonoscopy has important implications for the overall benefits of colorectal cancer screening programs. We evaluated the incidence of serious complications within 30 days after screening or surveillance colonoscopies in diverse clinical settings and to identify potential risk factors for complications. Methods Patients age 40 and over undergoing colonoscopy for screening, surveillance, or evaluation based an abnormal result from another screening test were enrolled through the National Endoscopic Database (CORI). Patients completed a standardized telephone interview approximately 7 and 30 days after their colonoscopy. We estimated the incidence of serious complications within 30 days of colonoscopy and identified risk factors associated with complications using logistic regression analyses. Results 21,375 patients were enrolled. Gastrointestinal bleeding requiring hospitalization occurred in 34 patients (incidence 1.59/1000 exams; 95% confidence interval [CI] 1.10–2.22). Perforations occurred in 4 patients (0.19/1000 exams; 95% CI 0.05–0.48), diverticulitis requiring hospitalization in 5 patients (0.23/1000 exams; 95% CI 0.08–0.54), and post-polypectomy syndrome in 2 patients (0.09/1000 exams; 95%CI 0.02–0.30). The overall incidence of complications directly related to colonoscopy was 2.01 per 1000 exams (95%CI 1.46–2.71). Two of the four perforations occurred without biopsy or polypectomy. The risk of complications increased with pre-procedure warfarin use and performance of polypectomy with cautery. Conclusions Complications after screening or surveillance colonoscopy are uncommon. Risk factors for complications include warfarin use and polypectomy with cautery. PMID:19850154

We used administrative and screening data from 2009 to 2010 to determine if Healthy Start (HS), an enhanced prenatal services program, is reaching the most vulnerable African American women in Kent County, Michigan. Women in HS are at higher risk of key predictors of birth outcomes compared with other women. To advance toward evidence-based HS program evaluations in the absence of randomized controlled trials, future studies using comparison groups need to appropriately establish baseline equivalence on a variety of risk factors related to birth outcomes.

A growing body of literature documents high rates of burnout, depression, and suicidal ideation among physicians and medical students. Barriers to seeking mental health treatment in this group include concerns about time, stigma, confidentiality, and potential career impact. The authors describe a 4-year trial of the Healer Education Assessment and Referral (HEAR) program, designed to increase mental health services utilization (MHSU) and decrease suicide risk (SR) as assessed by an Interactive Screening Program (ISP)at one US medical school. Over a 4-year period, medical students were engaged in face-to-face, campus-wide, educational group programs and were invited to complete an individual, online, and anonymous survey. This survey contained the 9-item Patient Health Questionnaire (PHQ-9) scale to assess depression and items to identify suicidal thoughts and behaviors, substance use, distressing emotional states, and the use of mental health treatment. Students who engaged in this ISP by corresponding electronically with a counselor after completing the survey were assessed and when indicated, referred to further treatment. The HEAR program was delivered to 1,008 medical students. Thirty-four percent (343/1,008) completed the online screening portion. Almost 8 % of respondents met the criteria for high/significant SR upon analysis of the completed screens. Ten out of 13 of the students with SR who dialogued with a counselor were not already receiving mental health treatment, indicating that this anonymous ISP identified a high proportion of an untreated, at risk, and potentially suicidal population. MHSU among medical students who completed the survey was 11.5 % in year 1 and 15.0 % by year 4. SR among medical students was 8.8 % in year 1 and 6.2 % in year 4 as assessed by the ISP. This novel interventional program identified at risk, potentially suicidal medical students at one institution. Based on this single-site experience, we suggest that future multisite studies incorporate a comparison group, acquire baseline (prematriculation) data regarding MHSU and SR, and use an individualized yet anonymous identification system to measure changes in individual participants' mental health status over time.

Early identification and intervention are critical for reducing the adverse effects of depression on academic and occupational performance. Cost-effective approaches are needed for identifying adolescents at high depression risk. This study evaluated the utility of school record review versus universal school-based depression screening for determining eligibility for an indicated depression intervention program implemented in the middle school setting. Algorithms derived from grades, attendance, suspensions, and basic demographic information were evaluated with regard to their ability to predict students' depression screening scores. The school information-based algorithms proved poor proxies for individual students' depression screening results. However, school records showed promise for identifying low, medium, and high-yield subgroups on the basis of which efficient screening targeting decisions could be made. Study results will help to guide school nurses who coordinate indicated depression intervention programs in school settings as they evaluate options of approaches for determining which students are eligible for participation. © 2012 Wiley Periodicals, Inc.

To determine prevalence of prenatal alcohol use in Brazzaville, Congo and to evaluate a prenatal screening tool for use in this population. A prospective population screening program of 3099 women at 10 prenatal care clinics in Brazzaville, Congo using the 1-Question screen. To validate the 1-Question screen in this population we screened 764 of these women again using the T-ACE as a gold standard for comparison study. The study outcomes were as follows: prevalence of self-reported prenatal alcohol use in Brazzaville using the 1-Question screen, estimation of number of drinking days, drinks per drinking day, most drinks on any one occasion. We also estimated the epidemiologic performance criteria for the 1-Question screen. The 3099 women screened were classified as follows: no risk 77% (n=2,384); at risk 3.7% (n=115); and as high risk 19.3% (n=600). Of the women reporting drinking during pregnancy, 87.4% reported drinking 4 or more drinks on any occasion. The agreement for detection of alcohol use during pregnancy by the 1-Question Screen and a positive T-ACE score was 94.7%. 23.3% of women attending prenatal care in Brazzaville reported alcohol use during pregnancy and 83% of them continued to drink after recognition of pregnancy. Prenatal alcohol exposure should be the focus of efforts to improve identification of alcohol use prior to and during pregnancy to improve maternal and child health.

Maternal well-being and its association to risk of developmental problems in children at school entry

PubMed Central

2010-01-01

Background Children at highest risk of developmental problems benefit from early identification and intervention. Investigating factors affecting child development at the time of transition to school may reveal opportunities to tailor early intervention programs for the greatest effectiveness, social benefit and economic gain. The primary objective of this study was to identify child and maternal factors associated with children who screened at risk of developmental problems at school entry. Methods An existing cohort of 791 mothers who had been followed since early pregnancy was mailed a questionnaire when the children were aged four to six years. The questionnaire included a screening tool for developmental problems, an assessment of the child's social competence, health care utilization and referrals, and maternal factors, including physical health, mental health, social support, parenting morale and sense of competence, and parenting support/resources. Results Of the 491 mothers (62%) who responded, 15% had children who were screened at high risk of developmental problems. Based on a logistic regression model, independent predictors of screening at high risk for developmental problems at age 5 were male gender (OR: 2.3; 95% CI: 1.3, 4.1), maternal history of abuse at pregnancy (OR: 2.4; 95% CI: 1.3, 4.4), and poor parenting morale when the child was 3 years old (OR: 3.9; 95% CI: 2.1, 7.3). A child with all of these risk factors had a 35% predicted probability of screening at high risk of developmental problems, which was reduced to 13% if maternal factors were favourable. Conclusions Risk factors for developmental problems at school entry are related to maternal well being and history of abuse, which can be identified in the prenatal period or when children are preschool age.

First-trimester screening for chromosomal abnormalities: advantages of an instant results approach.

PubMed

Norton, Mary E

2010-09-01

Protocols that include first trimester screening for fetal chromosome abnormalities have become standard of care throughout the United States. Earlier screening allows for first trimester diagnostic testing in cases found to be at increased risk. However, first trimester screening requires coordination of the nuchal translucency ultrasound screening (NT) and biochemical screening, during early, specific, narrow, but slightly different gestational age ranges. Instant results can often be provided at the time of the NT ultrasound if preceded by the programs that perform the biochemical analyses; this optimizes the benefits of the first trimester approach while improving efficiency and communication with the patient. This article discusses the benefits and logistics of such an approach. Copyright 2010 Elsevier Inc. All rights reserved.

The cystic fibrosis gene: Medical and social implications for heterozygote detection

The primary goal of mass screening programs for cystic fibrosis carriers should be to allow people to make more informed reproductive decisions. However, previous experience with genetic screening programs, including those for phenylketonuria and sickle cell disease, have revealed complex problems including error, confusion, and stigmatization. These problems could be greater with cystic fibrosis, since more than 8 million Americans may be carriers and entrepreneurial interests can be expected to promote screening in what could become a billion-dollar industry. The present frequency of the detectable mutation ({Delta}F{sub 508}), 75%, will complicate the counseling process. The sensitivity of the test tomore » detect at-risk couples would be 56%. The cost of screening could be as much as $2.2 million for each cystic fibrosis birth avoided. Regardless of improvements in the detection rate, implementation of population screening should be delayed until pilot studies that demonstrate its safety and effectiveness are completed. While studies are in progress, preconception testing should be offered to adult relatives of cystic fibrosis patients as part of a comprehensive program following institutional review board approval for compassionate use.« less

To assess the coverage of the newborn screening (NBS) program in Victoria, Australia, and identify potential predictors of not being screened. Victoria, Australia, 2003. The Victorian NBS program screens for phenylketonuria (PKU), cystic fibrosis, congenital hypothyroidism and more than 20 metabolic conditions, such as medium chain acyl-coenzyme A dehydrogenase (MCAD) deficiency. Victorian birth records (n = 63,018) were linked to Victorian NBS records (n = 62,876) using probabilistic record linkage. Binary logistic regression was used to identify potential predictors of not being screened. Uptake of NBS was 99.4% (62,643/63,018), resulting in 0.6% (375) of livebirths not matched to a NBS test. Neonatal death was the most significant factor associated with not being screened (relative risk (RR) = 407, 95%Cl = 314 to 526). After adjustment, surviving livebirths had an increased likelihood of not being matched to a NBS record if they: were transferred between hospitals (odds ratio (OR) = 2.4, 95% confidence interval (Cl) 1.5 to 3.9); were born at home (OR = 12.1, 95%Cl 6.3 to 23.3); resided in rural Victoria (OR = 2.6, 95%Cl 1.5 to 4.3); stayed in hospital for one day or less (OR = 4.6, 95%Cl 2.8 to 7.6); or whose mothers were primiparous (OR = 1.5, 95%Cl 1.1 to 2.1). NBS uptake is extremely high in Victoria with over 99% of livebirths screened. Particular risk factors for not having NBS have now been identified, which could lead to changes around monitoring neonates who are not born in a hospital, or leave/transfer hospital, before the NBS period (48-72 hours). Future studies could determine whether those not screened had opted-out or were not offered NBS.

Transgenerational effects of paternal Areca catechu nut chewing on offspring metabolic syndrome (MetS) risk in humans, on obesity and diabetes mellitus experimentally, and of paternal smoking on offspring obesity, are reported, likely attributable to genetic and epigenetic effects previously reported in betel-associated disease. We aimed to determine the effects of paternal smoking, and betel chewing, on the risks of early MetS in human offspring. The 13 179 parent-child trios identified from 238 364 Taiwanese aged ≥20 years screened at 2 community-based integrated screening sessions were tested for the effects of paternal smoking, areca nut chewing, and their duration prefatherhood on age of detecting offspring MetS at screen by using a Cox proportional hazards regression model. Offspring MetS risks increased with prefatherhood paternal areca nutusage (adjusted hazard ratio, 1.77; 95% confidence interval [CI], 1.23-2.53) versus nonchewing fathers (adjusted hazard ratio, 3.28; 95% CI, 1.67-6.43) with >10 years paternal betel chewing, 1.62 (95% CI, 0.88-2.96) for 5 to 9 years, and 1.42 (95% CI, 0.80-2.54) for <5 years betel usage prefatherhood (Ptrend=0.0002), with increased risk (adjusted hazard ratio, 1.95; 95% CI, 1.26-3.04) for paternal areca nut usage from 20 to 29 years of age, versus from >30 years of age (adjusted hazard ratio,1.61; 95% CI, 0.22-11.69). MetS offspring risk for paternal smoking increased dosewise (Ptrend<0.0001) with earlier age of onset (Ptrend=0.0009), independently. Longer duration of paternal betel quid chewing and smoking, prefatherhood, independently predicted early occurrence of incident MetS in offspring, corroborating previously reported transgenerational effects of these habits, and supporting the need for habit-cessation program provision. © 2016 American Heart Association, Inc.

We identified to what extent the Department of Defense postdeployment health surveillance program identifies at-risk drinking, alone or in conjunction with psychological comorbidities, and refers service members who screen positive for additional assessment or care. We completed a cross-sectional analysis of 333 803 US Army active duty members returning from Iraq or Afghanistan deployments in fiscal years 2008 to 2011 with a postdeployment health assessment. Alcohol measures included 2 based on self-report quantity-frequency items-at-risk drinking (positive Alcohol Use Disorders Identification Test alcohol consumption questions [AUDIT-C] screen) and severe alcohol problems (AUDIT-C score of 8 or higher)-and another based on the interviewing provider's assessment. Nearly 29% of US Army active duty members screened positive for at-risk drinking, and 5.6% had an AUDIT-C score of 8 or higher. Interviewing providers identified potential alcohol problems among only 61.8% of those screening positive for at-risk drinking and only 74.9% of those with AUDIT-C scores of 8 or higher. They referred for a follow-up visit to primary care or another setting only 29.2% of at-risk drinkers and only 35.9% of those with AUDIT-C scores of 8 or higher. This study identified missed opportunities for early intervention for at-risk drinking. Future research should evaluate the effect of early intervention on long-term outcomes.

To evaluate the impact of an intervention in primary care professionals on their current knowledge about colorectal cancer screening, subsequent surveillance recommendations and referral strategies. Cluster randomized controlled trial. Primary Care Centers in L'Hospitalet de Llobregat (Barcelona). Primary Care Professionals (doctors and nurses). Training session in six of the 12 centers (randomly selected) about the colorrectal cancer screening program, and three emails with key messages. Professionals and centers characteristics and two contextual variables; involvement of professionals in the screening program; information about colorectal cancer knowledge, risk factors, screening procedures, surveillance recommendations and referral strategies. The total score mean on the first questionnaire was 8.07 (1.38) and the second 8.31 (1.39). No statistically significant differences between the intervention and control groups were found, however, in 9 out of 11 questions the percentage of correct responses was increased in the intervention group, mostly related to the surveillance after the diagnostic examination. The intervention improves the percentage of correct answers, especially in those in which worst score obtained in the first questionnaire. This study shows that professionals are familiar with colorectal cancer screening, but there's a need to maintain frequent communication in order to keep up to date the information related to the colorectal cancer screening.

Background In 2007, the Cameroon Baptist Convention Health Services (CBCHS) implemented a screen-and-treat cervical cancer prevention program using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC). Methods We retrospectively analyzed 46,048 medical records of women who received care through the CBCHS Women’s Health Program from 2007 through 2014 to determine the prevalence and predictors of positive VIA-DC, rates of same day treatment, and cohort prevalence of invasive cervical cancer (ICC). Results Of the 44,979 women who were screened for cervical cancer, 9.0% were VIA-DC-positive, 66.8% were VIA-DC-negative, 22.0% were VIA-DC-inadequate (normal ectocervix, but portions of the transformation zone were obscured), and 2.2% were VIA-DC-uncertain (cervical abnormalities confounding VIA-DC interpretation). Risk factors significantly associated with VIA-DC-positive screen were HIV-positivity, young age at sexual debut, higher lifetime number of sexual partners, low education status and higher gravidity. In 2014, 31.1% of women eligible for cryotherapy underwent same day treatment. Among the 32,788 women screened from 2007 through 2013, 201 cases of ICC were identified corresponding to a cohort prevalence of 613 per 100,000. Conclusions High rate of VIA-DC-positive screens suggests a significant burden of potential cervical cancer cases and highlights the need for expansion of cervical cancer screening and prevention throughout the 10 regions of Cameroon. VIA-DC-inadequate rates were also high, especially in older women, and additional screening methods are needed to confirm whether these results are truly negative. In comparison to similar screening programs in sub-Saharan Africa there was low utilization of same day cryotherapy treatment. Further studies are required to characterize possible program specific barriers to treatment, for example cultural demands, health system challenges and cost of procedure. The prevalence of ICC among women who presented for screening was high and requires further investigation. PMID:27280882

Asymptomatic bacteriuria: when to screen and when to treat.

PubMed

Nicolle, Lindsay E

2003-06-01

Asymptomatic bacteriuria is common. Populations with structural or functional abnormalities of the genitourinary tract may have an exceedingly high prevalence of bacteriuria, but even healthy individuals frequently have positive urine cultures. Asymptomatic bacteriuria is seldom associated with adverse outcomes. Pregnant women and individuals who are to undergo traumatic genitourinary interventions are at risk for complications of bacteriuria and benefit from screening and treatment programs. Although screening is recommended for renal transplant recipients, the benefits for these patients are less clear. For other populations, including most bacteriuric individuals, negative outcomes attributable to asymptomatic bacteriuria have not been described. Treatment of asymptomatic bacteriuria in these patients is not beneficial and, in fact, may be associated with harmful outcomes, such as increased short-term frequency of symptomatic infection, adverse drug effects, and reinfection with organisms of increased antimicrobial resistance. Screening for asymptomatic bacteriuria and treatment is recommended for only selected groups where benefit has been shown. Many research questions still need to be addressed. Different populations have unique risk factors, and the benefits and risks of different management approaches for asymptomatic bacteriuria must continue to be addressed systematically in appropriate clinical trials.

Nuchal translucency and first trimester risk assessment: a systematic review.

2007-06-01

First-trimester risk assessment for fetal aneuploidy using nuchal translucency (NT) measurement is rapidly gaining popularity in the United States. In combination with maternal serum markers in the first trimester, the screening performance is exceptionally good, with detection rates of more than 80% at a screen positive rate of 5%. Recently, the method has been validated for screening for Down syndrome and other aneuploidies in multicenter trials in the United States and elsewhere. Compliance with established criteria for measurement of the NT is essential to achieve uniform reliability and high screening test sensitivity. There is an international consensus about the importance of specific training in the NT examination, conformity to standards of NT measurement, and regular audit for quality assurance. In the United States, the Nuchal Translucency Quality Review program has been developed to administer credentialing and quality review for registered practitioners. The Nuchal Translucency Quality Review credentials signify the proficiency of the sonographer or sonologist in NT measurement and participation in a regular quality assurance audit. We encourage accreditation of clinical sites offering first-trimester risk assessment to ensure the highest quality care.

Major US employers have great influence on the health care system because of the large number of employees for whom they provide health benefits and the billions of dollars they spend on health care. These companies must find ways to promote and improve health and health care, including by addressing racial and ethnic disparities. The communications company Verizon 38 percent of whose workforce is made up of racial and ethnic minorities, does so through a variety of initiatives to educate employees and to partner with health plans to increase screenings, care management, and other interventions. These initiatives include on-site mammography screening for employees; mailings that describe heightened breast cancer risks for minority populations; and data analysis to determine whether special programs should be put in place to target cardiovascular and other disease risks for racial and ethnic minorities. Between 200 and 300 female employees each year for the past three years have been screened at Verizon for breast cancer as a result, and the company is carrying out additional analyses to determine the impact on morbidity, mortality, and spending for that and other programs.

Bae, Jong-Myon; Shin, Sang Yop; Kim, Eun Hee

2015-01-01

Purpose This retrospective cohort study was conducted to estimate the optimal interval for gastric cancer screening in Korean adults with initial negative screening results. Materials and Methods This study consisted of voluntary Korean screenees aged 40 to 69 years who underwent subsequent screening gastroscopies after testing negative in the baseline screening performed between January 2007 and December 2011. A new case was defined as the presence of gastric cancer cells in biopsy specimens obtained upon gastroscopy. The follow-up periods were calculated during the months between the date of baseline screening gastroscopy and positive findings upon subsequent screenings, stratified by sex and age group. The mean sojourn time (MST) for determining the screening interval was estimated using the prevalence/incidence ratio. Results Of the 293,520 voluntary screenees for the gastric cancer screening program, 91,850 (31.29%) underwent subsequent screening gastroscopies between January 2007 and December 2011. The MSTs in men and women were 21.67 months (95% confidence intervals [CI], 17.64 to 26.88 months) and 15.14 months (95% CI, 9.44 to 25.85 months), respectively. Conclusion These findings suggest that the optimal interval for subsequent gastric screening in both men and women is 24 months, supporting the 2-year interval recommended by the nationwide gastric cancer screening program.

Hix-Small, Hollie; Alkherainej, Khaled

In the State of Kuwait, family physicians and pediatricians are responsible for identifying and referring children at risk of disability. The aims of this study were to better understand physician (1) use of developmental screening instruments, (2) referral practices for children at risk of developmental disability, (3) interpretation of screening results, and (4) anticipatory guidance topics prioritized over child screening. A nonprobability volunteer, self-selection sample of family physicians, general practitioners, and pediatricians (n = 398) completed a 60-item paper questionnaire. Items assessed included: (1) practitioner familiarity with, belief in, and use of screening instruments; (2) familiarity with early childhood intervention services; (3) perceived barriers to screening implementation; and (4) anticipatory topics prioritized over screening. Logistic regression was used to test a priori hypotheses. In general, family doctors and pediatricians practicing in public hospitals and primary health care centers in the State of Kuwait do not use or know how to use a developmental screening instrument, while over half prioritized immunization counseling over child screening. Screening confidence and training on using screening instruments increased the likelihood of tool use. Staff shortages, time constraints, and a perceived lack of Arabic screening instruments were barriers to tool use. Raising health care providers' awareness of standardized developmental screening instruments and establishment of an early identification system in the State of Kuwait are needed. Standardization and adaptation of technically sound Arabic-language screening tools for use in the State of Kuwait and physician training programs on screening are recommended.

In Malaysia, colorectal cancer is the most common cancer in males and the third most common in females. Mortality due to colorectal cancer can be effectively reduced with early diagnosis. This study was designed to look into colorectal cancer screening participation and its barriers among average risk individuals in Malaysia. A cross sectional study was conducted from August 2009 till April 2010 involving average risk individuals from 44 primary care clinics in West Malaysia. Each individual was asked whether they have performed any of the colorectal cancer screening methods in the past five years. The barrier questions had three domains: patient factors, test factors and health care provider factors. Descriptive analysis was achieved using Statistical Program for Social Sciences (SPSS) version 12.0. A total of 1,905 average risk individuals responded making a response rate of 93.8%. Only 13 (0.7%) respondents had undergone any of the colorectal cancer screening methods in the past five years. The main patient and test factors for not participating were embarrassment (35.2%) and feeling uncomfortable (30.0%), respectively. There were 11.2% of respondents who never received any advice to do screening. The main reason for them to undergo screening was being advised by health care providers (84.6%). The study showed that participation in colorectal cancer screening in Malaysia is extremely low and multiple factors contribute to this situation. Given the importance of the disease, efforts should be made to increase colorectal cancer screening activities in Malaysia.

Internet-based health information will enable us to interact with many people despite distance and time constraints. Informational media by computer is expected to become an important factor that affects health behavior. This study was done to develop an accessible multimedia program about breast self-examination on the Internet. This study was designed by using the two steps of need assessment and program development. For the need assessment step, a survey was carried out. The sample consisted of the 82 women of Yonsei University selected by convenient random sampling. At the program development step, screen design took into account perspectives of computer engineering. A storyboard for every screen was made via screen design and then ported to computer using the Netscape Navigator program. A breast self-examination program was developed using Netscape 4.0 on the Windows 98 platform. The multimedia program, including text, graphics, animation, and sound, was constructed with HTML language using Memo Sheet in Netscape Navigator. The contents of health information posted on the Internet included general information about breast cancer, the importance of breast self-examination, self-risk appraisal of breast cancer, the diverse methods about breast self-examination, the monthly check list graph, and social network for consultation. It is possible to interact with clients through the Question and Answer function on screen. This Internet-based health information program provides enough information, which can be accessed using search systems on the Internet.

To demonstrate the performance of Hb Bart's Disease prevention in Guangxi Zhuang Autonomous Region, China. A prenatal control program for Hb Bart's disease was conducted from January 2006 to December 2012. A total of 17,555 pregnant women were screened for α-thalassemia in our prenatal screening program. Pregnancy at-risk for Hb Bart's disease was offered the choice of direct invasive testing or the non-invasive approach with serial ultrasonography. A total of 1425 at-risk couples attended the prenatal diagnosis. Three hundred ninety couples were screened at our own hospital, and the remaining 1035 couples were referred from other hospitals. Two hundred and three pregnant women chose non-invasive approach, and 1122 chose invasive testing. A total of 365 fetuses were diagnosed with Hb Bart's disease. All cases were finally confirmed by fetal DNA analysis. Eighty-two cases (22.4%) were diagnosed by chorionic villous sampling and 194 (53.2%) by amniocentesis samples. The other 89 (24.4%) cases were performed by cordocentesis. All of the affected pregnancies were terminated. Implementation of a prevention and control program accompanying with a referral system for prenatal diagnosis is technically feasible in Guangxi Zhuang Autonomous Region, China.

Background Breast cancer (BC) detection in women with a genetic susceptibility or strong family history is considered mandatory compared with BC screening in the general population. However, screening modalities depend on the level of risk. Here we present an update of our screening programs based on risk classification. Methods We defined different risk categories and surveillance strategies to identify early BC in 1325 healthy women recruited by the Modena Study Group for familial breast and ovarian cancer. Four BC risk categories included BRCA1/2 carriers, increased, intermediate, and slightly increased risk. Women who developed BC from January 1, 1994, through December 31, 2005 (N = 44) were compared with the number of expected cases matched for age and period. BRCA1/2 carriers were identified by mutational analysis. Other risk groups were defined by different levels of family history for breast or ovarian cancer (OC). The standardized incidence ratio (SIR) was used to evaluate the observed and expected ratio among groups. All statistical tests were two-sided. Results After a median follow-up of 55 months, there was a statistically significant difference between observed and expected incidence [SIR = 4.9; 95% confidence interval (CI) = 1.6 to 7.6; p < 0.001]. The incidence observed among BRCA carriers (SIR = 20.3; 95% CI = 3.1 to 83.9; P < 0.001), women at increased (SIR = 4.5; 95% CI = 1.5 to 8.3; P < 0.001) or intermediate risk (SIR = 7.0, 95% CI = 2.0 to 17.1; P = 0.0018) was higher than expected, while the difference between observed and expected among women at slightly increased risk was not statistically significant (SIR = 2.4, 95% CI = 0.9 to 8.3; P = .74). Conclusion The rate of cancers detected in women at high risk according to BRCA status or strong family history, as defined according to our operational criteria, was significantly higher than expected in an age-matched general population. However, we failed to identify a greater incidence of BC in the slightly increased risk group. These results support the effectiveness of the proposed program to identify and monitor individuals at high risk, whereas prospective trials are needed for women belonging to families with sporadic BC or OC.

Osteoporosis affects approximately 26% of women and 4% of men after the age of 65 years. However, the diffusion of knowledge about osteoporosis risk factors, prevention and treatment remains low. The purpose of this longitudinal study was to investigate the value of adding initial and refresher osteoporosis education classes to a bone health screening program. A convenience sample of 376 men (n = 62) and women (n = 314) over the age of 62 years was assigned randomly to the Screening plus Education (n =193) or Screening only (n = 183) groups. Participants in both study groups demonstrated an increase in knowledge about osteoporosis, regardless of group assignment and other factors, over the two years of the study. Self-reported calcium use increased for all women and for men in the education group from baseline to year one, with a decline thereafter. There was no effect on exercise behaviors. This study points out the critical need for a more comprehensive and personalized bone health program that includes more than classroom-based education. Copyright © 2010 Mosby, Inc.

Cervical cancer screening with Pap smear test is a cost-effective method. The Ministry of Health in Turkey recommends that it be performed once every five years after age 35. The purpose of this study was to determine the cervical cancer risk levels of women between 35 and 69, and the intervals they have the Pap smear test, and to investigate the relation between the two. This study was performed on 227 women aged between 35 and 69 living in Balçova District of İzmir province. Using the cervical cancer risk index program of Harvard School of Public Health, the cervical cancer risk level of 70% of the women was found below average, 22.1% average, and 7.9% above average. Only 52% of the women have had Pap smear test at least once in their lives. The percentage screening regularly in conformity with the national screening standard was 39.2%. Women in the 40-49 age group, were married, conformed significantly more (p<0.05) to the national screening standard. Compliance also increased with the level of education and decreased with the cervical cancer risk level (p<0.05). A logistic regression model was constructed including age, education level, menstruation state of the women and the economic level of the family. Not having the Pap smear test in conformity with the national cervical cancer screening standard in 35-39 age group was 2.52 times more than 40-49 age group, while it was 3.26 times more in 60-69 age group (p< 0.05). Not having Pap smear test in 35-39 age group more than other groups might result from lack of information on the cervical cancer national screening standard and the necessity of having Pap smear test. As for 60-69 age group, the low education level might cause not having Pap smear test. Under these circumstances, the cervical cancer risk levels should be determined and the individuals should be informed. Providing Pap smear test screening service to individuals in the target group of national screening standard, as a public service may resolve the inequalities due to age and educational differences.

Despite a high prevalence of liver disease in Viet Nam, there has been no nationwide approach to the disease and no systematic screening of at-risk individuals. Risk factors include chronic hepatitis B (estimated prevalence of 12%), chronic hepatitis C (at least 2% prevalence), and heavy consumption of alcohol among men. This combination of factors has resulted in liver cancer being the most common cause of cancer death in Viet Nam. There is a general lack of understanding by both the general public and health-care providers about the major risk to health that liver disease represents. We report here the initial steps taken as part of a comprehensive approach to liver disease that will ultimately include nationwide education for health-care providers, health educators, and the public; expansion of nationwide screening for hepatitis B and C followed by hepatitis B virus vaccination or treatment of chronic hepatitis B and/or hepatitis C; education about alcoholic liver disease; long-term surveillance for liver cancer; reduction of infection transmission related to medical, commercial, and personal re-use of contaminated needles, syringes, sharp instruments, razors, and inadequately sterilized medical equipment; and ongoing collection and analysis of data about the prevalence of all forms of liver disease and the results of the expanded screening, vaccination, and treatment programs. We report the beginning results of our pilot hepatitis B screening program. We believe that this comprehensive nationwide approach could substantially reduce the morbidity and mortality from liver disease and greatly lessen the burden in terms of both lives lost and health-care costs. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

The shift towards earlier stages of disease advancement at diagnosis when introducing mammography screening is expected to affect the treatment costs of breast cancer. We collected data on hospital resource use in Norway following a breast cancer diagnosis for the period 1 January, 2008 through 31 December, 2009 for women aged 50-69 years, diagnosed with breast cancer during the period 1 January, 1999 through 31 December, 2009. We estimated treatment costs using a function that included the probability of being at risk for receiving treatment, estimated by means of the Cox proportional hazard model. In total, 16,045 patients were included for the analyses among which 10.5 % died during the study period. The mean 10-year per-person treatment cost was €31,940 (95 % CI €31,030-32,880), and lower for cancers detected within the public screening program (€30,730) than for those detected elsewhere (€36,230). For ductal carcinoma in situ (DCIS) and cancers in stages I thru IV, treatment costs were €15,740, €23,570, €46,550, €55,230 and €60,430, respectively. Interval cancers occurring within the screening program were generally more resource demanding than both cancers detected at screening or elsewhere. Ten-year treatment costs increased by increasing stage at diagnosis. Patients whose cancer was detected within the public screening program had lower treatment costs than those detected elsewhere. Interval cancers had higher costs than others.

Infection from Hepatitis B primarily results from peri-partum vertical transmission and the risk increases in the presence of hepatitis B e antigen. We aimed to evaluate a new screening program for hepatitis B in pregnant women as a component of antenatal services in a marginalized population. Counseling and screening for hepatitis B screening was offered to all women at the first visit, at Shoklo Malaria Research Unit (SMRU) antenatal clinics on the Thai-Myanmar border.  Point-of-care rapid diagnostic tests (RDT) were used throughout the period of evaluation. A certified Thai Public Health laboratory at Mae Sot Hospital verified RDT positive cases using enzyme-linked immunosorbent assay (ELISA) for HBsAb and HBeAg. Risk factors for hepatitis B were identified by data linkage to antenatal care records. There were 523 (8.5%) RDT positive for HBsAg among 6158 women tested (Aug-2012 to April-2014). Of these 373 (96.9%) of 385 sent for confirmation were positive by ELISA i.e. RDT false positive rate of 3.1% (95% CI 1.7- 5.4). The overall confirmed HbsAg prevalence was 8.3% (511/6158) (95% CI 7.6-9.0). HBeAg prevalence was 32.7% (114/350) (95% CI 27.9-37.7) of cases tested. Risk factors for HBsAg positivity included age >25 years (OR 1.24, CI 1.03-1.49, p 0.021) and Karen heritage (OR 1.73, CI 1.39-2.15, p < 0.01). High hepatitis B seroprevalence amongst migrants and refugees accessing SMRU antenatal services likely reflects that of Kayin State, Myanmar, and perinatal prevention programs are required. False positive cases with HBsAg RDT complicate what is theoretically a straightforward screening.

The province of Ferrara has one of the highest incidences of colorectal cancer (CRC) in Italy. In January 2000, we set up a colonoscopy screening program focussing on first-degree relatives of CRC patients. We now report the results 5 years after the beginning of the project. SCREENEES AND METHODS: In October 1999, we started a campaign stressing the usefulness of colonoscopy for the first-degree relatives of CRC patients. Subjects included in the screening program were aged between 45 and 75 years with at least one first-degree relative affected by CRC. They were invited to an interview where a physician suggested colonoscopy as a screening option. In 5 years, 776 subjects were interviewed and 733 (94.4%) agreed to an endoscopic examination (M/F:375/401; mean age 55 years): 562 colonoscopies were performed. Adenomas and cancers were found in 122 (21.7%) and 12 (2.1%) subjects, respectively. Histological examination in 181 persons with lesions (32.8%) showed (most serious lesion quoted) 47 hyperplastic polyps (26% of all lesions), 2 serrated adenomas (1.1%), 68 tubular adenomas (48%), 24 tubulovillous adenomas (13.3%), 9 adenomas with high grade dysplasia (5%) and 12 adenocarcinomas (6.6%). The majority of the cancers were at an early stage (8 Dukes A and 3 Dukes B). Sedation was used in only 42 colonoscopies (7.5%). A colonoscopy-based screening in this selected high-risk population is feasible. Even without sedation subjects readily agreed to the endoscopic procedure. We identified a significant number of advanced neoplasms and cancers at an early stage suggesting that this could be a useful tool in early identification of CRC.

Bronchiectasis is one of the common chronic respiratory diseases and associated with respiratory morbidity and mortality. However, neither its prevalence nor its etiology is well-defined. We aimed to estimate the prevalence and risk factors of bronchiectasis in adults. In a retrospective study, we analyzed radiologic findings on chest computed tomography (CT) images performed as part of a health-screening program. From January to December 2008, 1,409 (24.6%) of 5,727 participants in the screening program of a health promotion center at a university hospital underwent chest CT scans based on the subject's decision. Bronchiectasis was diagnosed, if there was abnormal bronchial dilatation in any area of both lungs on chest CT. Respiratory symptoms, smoking status, and past medical history were also analyzed to define clinical characteristics and risk factors of bronchiectasis. Of 1,409 patients (aged 23-86 years), who were screened for respiratory diseases using chest CT for one year in a health promotion center, 129 patients (9.1%) were diagnosed with bronchiectasis. The prevalence of bronchiectasis was higher in females than in males (11.5% vs. 7.9%, p = 0.022) and increased with age. Respiratory symptoms were reported in 53.7% of subjects. Previous history of tuberculosis (TB) (OR 4.61, 95% CI 2.39-8.88, p = 0.001) and age (OR 2.49, 95% CI 1.56-3.98, p = 0.001) were significantly associated with bronchiectasis. This retrospective analysis of chest CT findings in health screening examinees revealed a very high prevalence of bronchiectasis in adults. Previous TB infection is one of the major causes of bronchiectasis.

Survival of childhood, adolescent and young adult (CAYA) cancers has increased with progress in the management of the treatments and has reached more than 80% at 5 years. Nevertheless, these survivors are at great risk of second cancers and non-malignant co-morbidities in later life. DeNaCaPST is a non-interventional study whose aim is to organize a national screening for thyroid cancer and breast cancer in survivors of CAYA cancers. It will study the compliance with international recommendations, with the aim, regarding a breast screening programme, of offering for every woman living in France, at equal risk, an equal screening. DeNaCaPST trial is coordinated by the INSERM 1018 unit in cooperation with the LEA (French Childhood Cancer Survivor Study for Leukaemia) study's coordinators, the long term follow up committee and the paediatric radiation committee of the SFCE (French Society of Childhood Cancers). A total of 35 centres spread across metropolitan France and la Reunion will participate. FCCSS (French Childhood Cancer Survivor Study), LEA and central registry will be interrogated to identify eligible patients. To participate, centers agreed to perform a complete "long-term follow-up consultations" according to good clinical practice and the guidelines of the SFCE (French Society of Children Cancers). As survival has greatly improved in childhood cancers, detection of therapy-related malignancies has become a priority even if new radiation techniques will lead to better protection for organs at risk. International guidelines have been put in place because of the evidence for increased lifetime risk of breast and thyroid cancer. DeNaCaPST is based on these international recommendations but it is important to recognize that they are based on expert consensus opinion and are supported by neither nonrandomized observational studies nor prospective randomized trials in this specific population. Over-diagnosis is a phenomenon inherent in any screening program and therefore such programs must be evaluated.

A prospective study was undertaken to develop an evidence-based outreach chlamydia screening program and to assess the viability and efficiency of this complementary approach to chlamydia testing within the routine operations of a primary healthcare service. A primary healthcare service based in Townsville, Queensland, Australia, identified high-prevalence groups for chlamydia in the community. Subsequently, a series of outreach clinics were established and conducted between August 2004 and November 2005 at a defence force unit, a university, high school leavers' festivities, a high school catering for Indigenous students, youth service programs, and backpacker accommodations. All target groups were easily accessible and yielded high participation. Chlamydia prevalence ranged between 5 and 15% for five of the six groups; high school leavers had no chlamydia. All participants were notified of their results and all positive cases were treated (median treatment interval 7 days). Five of the six assessed groups were identified as viable for screening and form the basis for the ongoing outreach chlamydia screening program. The present study developed an evidence-based outreach chlamydia screening program and demonstrated its viability as a complementary approach to chlamydia testing within the routine operations of the primary healthcare service, i.e. without the need for additional funding. It contributes to the evidence base necessary for a viable and efficient chlamydia management program. Although the presented particulars may not be directly transferable to other communities or health systems, the general two-step approach of identifying local high-risk populations and then collaborating with community groups to access these populations is.

Alcohol use patterns that are hazardous for one's health is prevalent among DWI (driving while intoxicated) offenders and is a key predictor of recidivism. The aim of this program evaluation was to determine the feasibility and usability of implementing a computer-assisted screening, brief intervention and referral to treatment (SBIRT) program for DWI offenders to enable the identification of those in need of treatment services soon after arrest. Our treatment program consisted of a web-based, self-guided screening tool for assessing alcohol use patterns and generating a personalized feedback report that is then used to deliver a brief motivational intervention and if needed, a referral to treatment. Between August and November 2014, all DWI offenders attending orientation for pre-trial supervision were assessed for eligibility. Of the 129 eligible offenders, 53.5 percent enrolled and the first 50 were asked to complete a usability and satisfaction questionnaire. The results demonstrated that the majority of those screened reported at-risk alcohol use patterns requiring referral to treatment. Clients reported high ratings of usability and satisfaction with the screening tool and personalized feedback report, which did not significantly differ depending on alcohol use patterns. There were relatively few technical difficulties, and the majority of clients reported high levels of satisfaction with the overall SBIRT program. Results of this program evaluation suggest that computer-assisted SBIRT may be successfully implemented within the criminal justice system to DWI offenders soon after arrest; however, further research is required to examine its effects on treatment utilization and recidivism.

Although colorectal cancer is a leading cause of death in Canada, it is curable if detected in the early stages. Flexible sigmoidoscopy has been shown to reduce the incidence and mortality of colorectal cancer in patients who are at average risk for this disease and, therefore, is an appropriate screening intervention. Moreover, it may be performed by nonphysicians. A program to enable registered nurses to perform flexible sigmoidoscopy to increase colorectal cancer screening capacity in Ontario was developed. This program incorporated practical elements learned from other jurisdictions as well as specific regional considerations to fit within the health care system of Ontario. The nurses received structured didactic and simulation training before performing sigmoidoscopies on patients under physician supervision. After training, nurses were evaluated by two assessors for their ability to perform complete sigmoidoscopies safely and independently. To date, 17 nurses have achieved independence in performing flexible sigmoidoscopy at 14 sites. In total, nurses have screened >7000 Ontarians, with a cancer detection rate of 5.1 per 1000 screened, which is comparable with rates in other jurisdictions and with sigmoidoscopy performed by gastroenterologists, surgeons and other trained nonphysicians. We have shown, therefore, that with proper training and program structure, registered nurses are able to perform flexible sigmoidoscopy in a safe and thorough manner resulting in a significant increase in access to colorectal cancer screening.

Qualitative comparative analysis (QCA) was developed over 25 years ago to bridge the qualitative and quantitative research gap. Upon searching PubMed and the Journal of Mixed Methods Research , this review identified 30 original research studies that utilized QCA. Perceptions that QCA is complex and provides few relative advantages over other methods may be limiting QCA adoption. Thus, to overcome these perceptions, this article demonstrates how to perform QCA using data from fifteen institutions that implemented universal tumor screening (UTS) programs to identify patients at high risk for hereditary colorectal cancer. In this example, QCA revealed a combination of conditions unique to effective UTS programs. Results informed additional research and provided a model for improving patient follow-through after a positive screen.

To identify possible early predictors (symptoms and biomarkers) of celiac disease, compare symptoms before and after screening, and evaluate the diagnostic efficacy of serologic screening for celiac disease in an adult Danish population. This cross-sectional population-based study was based on the 5-year follow-up of the Health2006 cohort, where 2297 individuals were screened for celiac disease; 56 were antibody positive and thus invited to clinical evaluation. Eight were diagnosed with biopsy-verified celiac disease. A follow-up questionnaire was sent to antibody-positive individuals 19 months after the clinical evaluation to obtain information on their symptoms and their experience with participation in the screening. Before screening, participants subsequently diagnosed with celiac disease did not differ from the rest of the population with respect to symptoms, but had significantly lower total cholesterol. Tissue transglutaminase IgA antibodies with a cut-off of 10 U/ml had a positive predictive value of 88%. The majority of participants were satisfied with their participation in the screening program. Individuals with celiac disease were generally satisfied with having been diagnosed and 71% felt better on a gluten-free diet. There were no differences in the prevalence of symptoms between participants with and without screening-detected celiac disease, confirming that risk stratification in a general population by symptoms is difficult. The majority of participants diagnosed with celiac disease felt better on a gluten-free diet despite not reporting abdominal symptoms before diagnosis and participants in the clinical evaluation were generally satisfied with participation in the screening program.

Electromagnetic Navigational Bronchoscopy

Port, Jeffrey; Harrison, Sebron

2013-01-01

Despite advances in technology and treatment options, lung cancer remains a deadly disease. National screening programs are being instituted in an attempt to discover lung cancer in high-risk individuals at an earlier stage. Such screening programs invariably discover small peripheral nodules that previously would not have been clinically apparent; the management of such lesions can be challenging. Current diagnostic options such as percutaneous biopsy are effective; however, they are hindered by their risk of morbidity such as pneumothorax. Electromagnetic bronchoscopy (ENB) is an emerging technology that allows the practitioner the ability to both sample and treat small peripheral pulmonary lesions. In experienced centers, ENB provides high rates of diagnostic yield for small lesions and a complication rate significantly lower than that of more conventional diagnostic modalities. Although there are current barriers to its widespread utilization (cost, specialized imaging, technical training), these obstacles will handled similarly to any other emerging technology and will likely not be long-term impediments to its use.

Background Although cervical cancer is largely preventable through screening, detection and treatment of precancerous abnormalities, it remains one of the top causes of cancer-related morbidity and mortality globally. Objectives The objective of this systematic review is to understand the evidence of the effect of cervical cancer education compared to control conditions on cervical cancer screening rates in eligible women population at risk of cervical cancer. We also sought to understand the effect of provider recommendations for screening to eligible women on cervical cancer screening (CCS) rates compared to control conditions in eligible women population at risk of cervical cancer. Methods We used the PICO (Problem or Population, Interventions, Comparison and Outcome) framework as described in the Cochrane Collaboration Handbook to develop our search strategy. The details of our search strategy has been described in our systematic review protocol published in the International Prospective Register of systematic reviews (PROSPERO). The protocol registration number is CRD42016045605 available at: http://www.crd.york.ac.uk/prospero/display_record.asp?src=trip&ID=CRD42016045605. The search string was used in Pubmed, Embase, Cochrane Systematic Reviews and Cochrane CENTRAL register of controlled trials to retrieve study reports that were screened for inclusion in this review. Our data synthesis and reporting was guided by the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). We did a qualitative synthesis of evidence and, where appropriate, individual study effects were pooled in meta-analyses using RevMan 5.3 Review Manager. The Higgins I2 was used to assess for heterogeneity in studies pooled together for overall summary effects. We did assessment of risk of bias of individual studies included and assessed risk of publication bias across studies pooled together in meta-analysis by Funnel plot. Results Out of 3072 study reports screened, 28 articles were found to be eligible for inclusion in qualitative synthesis (5 of which were included in meta-analysis of educational interventions and 8 combined in meta-analysis of HPV self-sampling interventions), while 45 were excluded for various reasons. The use of theory-based educational interventions significantly increased CCS rates by more than double (OR, 2.46, 95% CI: 1.88, 3.21). Additionally, offering women the option of self-sampling for Human Papillomavirus (HPV) testing increased CCS rates by nearly 2-fold (OR = 1.71, 95% CI: 1.32, 2.22). We also found that invitation letters alone (or with a follow up phone contact), making an appointment, and sending reminders to patients who are due or overdue for screening had a significant effect on improving participation and CCS rates in populations at risk. Conclusion Our findings supports the implementation of theory-based cervical cancer educational interventions to increase women’s participation in cervical cancer screening programs, particularly when targeting communities with low literacy levels. Additionally, cervical cancer screening programs should consider the option of offering women the opportunity for self-sample collection particularly when such women have not responded to previous screening invitation or reminder letters for Pap smear collection as a method of screening.

Although some health care entities are addressing food insecurity among patients because of associations with disease risk and management, little is known about the components of these initiatives. Methods The Systematic Screening and Assessment Method was used to conduct a landscape assessment of US health care entity–based programs that screen patients for food insecurity and connect them with food resources. A network of food insecurity researchers, experts, and practitioners identified 57 programs, 22 of which met the inclusion criteria of being health care entities that 1) screen patients for food insecurity, 2) link patients to food resources, and 3) target patients including adults aged 50 years or older (a focus of this assessment). Data on key features of each program were abstracted from documentation and telephone interviews. Results Most programs (n = 13) focus on patients with chronic disease, and most (n = 12) partner with food banks. Common interventions include referrals to or a list of food resources (n = 19), case managers who navigate patients to resources (n = 15), assistance with federal benefit applications (n = 14), patient education and skill building (n = 13), and distribution of fruit and vegetable vouchers redeemable at farmers markets (n = 8). Most programs (n = 14) routinely screen all patients. Conclusion The programs reviewed use various strategies to screen patients, including older adults, for food insecurity and to connect them to food resources. Research is needed on program effectiveness in improving patient outcomes. Such evidence can be used to inform the investments of potential stakeholders, including health care entities, community organizations, and insurers. PMID:29144894

Purpose To assess the risk of breast cancer in women with false-positive screening results according to radiologic classification of mammographic features. Materials and Methods Review board approval was obtained, with waiver of informed consent. This retrospective cohort study included 521 200 women aged 50-69 years who underwent screening as part of the Spanish Breast Cancer Screening Program between 1994 and 2010 and who were observed until December 2012. Cox proportional hazards regression analysis was used to estimate the age-adjusted hazard ratio (HR) of breast cancer and the 95% confidence interval (CI) in women with false-positive mammograms as compared with women with negative mammograms. Separate models were adjusted for screen-detected and interval cancers and for screen-film and digital mammography. Time without a breast cancer diagnosis was plotted by using Kaplan-Meier curves. Results When compared with women with negative mammograms, the age-adjusted HR of cancer in women with false-positive results was 1.84 (95% CI: 1.73, 1.95; P < .001). The risk was higher in women who had calcifications, whether they were (HR, 2.73; 95% CI: 2.28, 3.28; P < .001) or were not (HR, 2.24; 95% CI: 2.02, 2.48; P < .001) associated with masses. Women in whom mammographic features showed changes in subsequent false-positive results were those who had the highest risk (HR, 9.13; 95% CI: 8.28, 10.07; P < .001). Conclusion Women with false-positive results had an increased risk of breast cancer, particularly women who had calcifications at mammography. Women who had more than one examination with false-positive findings and in whom the mammographic features changed over time had a highly increased risk of breast cancer. Previous mammographic features might yield useful information for further risk-prediction models and personalized follow-up screening protocols.

Medical rehabilitation seems suitable for implementing multimodal interventions for the treatment of type 2 diabetes. Rehabilitation in Germany on principle requires that insurees file an application. Proactive screening for rehabilitation need has only been explored in pilot projects so far. It seems a promising attempt to assess rehab need by questionnaire especially in patients with type 2 diabetes. We do not know though how patients who have been screened positive for rehab need differ from other patients with type 2 diabetes as to their health and risk profiles. This could provide an indication of the validity of the proactive approach. Members of an Allgemeine Ortskrankenkasse (AOK) Disease Management Program (DMP) for type 2 diabetes were screened for rehab need by questionnaire. 13 diabetes-specific problem areas were assessed. Problems were assigned to 10 specific treatments (problem-treatment-pairs). Rehab need was presumed if patients needed 3 or more treatments. Patients were then compared to regular rehab patients as well as patients with type 2 diabetes from primary care medical offices. From 5500 DMP-patients 829 returned the questionnaire (return rate: 15.5%). From these 94% met the criteria for rehab need; of these 55% needed 6 or more treatments (complex problems). Patients who screened positive for rehab suffered from more health problems and had worse risk profiles as compared to patients from medical offices, and disease burden was comparable or worse as compared to regular rehab patients. This indicates that proactive screening for rehab need in patients with type 2 diabetes leads to reasonable (valid) results. The very low return rate suggests that the sample may be considerably biased, though. Possibly, mainly patients with greater impairment to health responded to the screening. © Georg Thieme Verlag KG Stuttgart · New York.

Recent evidence questioning the effectiveness of prostate-specific antigen testing leave community-based prostate cancer (CaP) outreach programs with a dilemma between promoting screening and highlighting screening risks. CaP survivors are uniquely positioned to address this problem by drawing upon real-life experiences to share nuanced information and perspectives. While CaP survivors have historically been incorporated into outreach programs, little is known about their impact on psychosocial outcomes and their effectiveness compared to professional health educators. This study addressed these gaps through a quasi-experimental design where African American men attended a CaP screening session conducted by a health educator (HE) or survivor educator (SV). The presentation included prostate cancer statistics, CaP information, and descriptions of CaP screening tests. SV were encouraged to bolster their presentations with personal stories whereas HE maintained fidelity to the curriculum content. All participants completed pre- and post-test questionnaires. Our sample comprised a total of 63 participants (HE group = 32; SV group = 31) with an age range of 40-70 years. Decision self-efficacy increased significantly in the SV group (p = 0.01) whereas perceived screening risks reduced significantly in the HE group (p < 0.001). No significant changes were found in knowledge, subjective norms, outcome expectancies, and screening benefits. Survivor educators were found to have significantly greater appeal (p = 0.03), identification with audience (p = 0.01), and liking (p = 0.03). Training CaP survivors as health educators might be a viable strategy for community-based cancer communication efforts confronted by the CaP screening controversy. We discuss conceptual and programmatic implications of our findings and present directions for future research.

In Yemen, the prevalence of sickle cell trait and β-thalassemia trait are high. The aim of this premarital program is to identify sickle cell and thalassemia carrier couples in Yemen before completing marriages proposal, in order to prevent affected birth. This can be achieved by applying a low-cost premarital screening program using simple blood tests compatible with the limited health resources of the country. If microcytosis or positive sickle cell is found in both or one partner has microcytosis and the other has positive sickle cell, so their children at high risk of having sickle cell or/and thalassemia diseases. Carrier couples will be referred to genetic counseling. The outcomes of this preventive program are predicted to decrease the incidence of affected birth and reduce the health burden of these disorders. The success of this program also requires governmental, educational and religious supports. PMID:25003062

Ecological Screening Values for Surface Water, Sediment, and Soil: 2005 Update

DOE Office of Scientific and Technical Information (OSTI.GOV)

Friday, G. P.

2005-07-18

One of the principal components of the environmental remediation program at the Savannah River Site (SRS) is the assessment of ecological risk. Used to support CERCLA, RCRA, and DOE orders, the ecological risk assessment (ERA) can identify environmental hazards and evaluate remedial action alternatives. Ecological risk assessment is also an essential means for achieving DOE's risk based end state vision for the disposition of nuclear material and waste hazards, the decommissioning of facilities, and the remediation of inactive waste units at SRS. The complexity of an ERA ranges from a screening level ERA (SLERA) to a full baseline ERA. Amore » screening level ecological risk assessments, although abbreviated from a baseline risk assessment, is nonetheless considered a complete risk assessment (EPA, 2001a). One of the initial tasks of any ERA is to identify constituents that potentially or adversely affect the environment. Typically, this is accomplished by comparing a constituent's maximum concentration in surface water, sediment, or soil with an ecological screening value (ESV). The screening process can eliminate many constituents from further consideration in the risk assessment, but it also identifies those that require additional evaluation. This document is an update of a previous compilation (Friday, 1998) and provides a comprehensive listing of ecological screening values for surface water, sediment, and soil. It describes how the screening values were derived and recommends benchmarks that can be used for ecological risk assessment. The sources of these updated benchmarks include the U.S. Environmental Protection Agency (EPA), U.S. Fish and Wildlife Service (USFWS), U.S. Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), Oak Ridge National Laboratory (ORNL), the State of Florida, the Canadian Council of Ministers of the Environment (CCME), the Dutch Ministry of the Environment (RIVM), and the scientific literature. It should be noted that ESV's are continuously revised by the various issuing agencies. The references in this report provide the citations of each source and, where applicable, the internet address where they can be accessed. Although radiological screening values are not included herein due to space limitations, these have been recently derived by a technical working committee sponsored by the U.S. Department of Energy (DOE 2002, 2004). The recommended ecological screening values represent the most conservative concentrations of the cited sources, and are to be used for screening purposes only. They do not represent remedial action cleanup levels. Their use at locations other than SRS should take into account environmental variables such as water quality, soil chemistry, flora and fauna, and other ecological attributes specific to the ecosystem potentially at risk.« less

Risk for Maternal Harsh Parenting in High-Risk Families From Birth to Age Three: Does Ethnicity Matter?

PubMed Central

Fisher, Philip A.; Kim, Hyoun K.

2017-01-01

Child maltreatment prevention programs typically identify at-risk families by screening for risk with limited consideration of how risk might vary by ethnicity. In this study, longitudinal data from mothers who participated in a randomized clinical trial of a home-visitation, child maltreatment prevention program (N=262) were examined to determine whether risk for harsh parenting differed among mothers who identified themselves as Spanish-speaking Latinas (n=64), English-speaking Latinas (n=102), or non-Latina Caucasians (n=96). The majority of the participants were first-time mothers (58.4%), and the average age of all participants was 23.55 years (SD=6.04). At the time of their infants’ births, the Spanish-speaking Latina mothers demonstrated higher SES risk, whereas the English-speaking Latina and non-Latina Caucasian mothers demonstrated higher psychosocial risk. Three years later, the English-speaking Latina and non-Latina Caucasian mothers reported harsher parenting behaviors than the Spanish-speaking Latina mothers. The need for prevention programs to consider how risk and protective factors differ by ethnic group membership when identifying at-risk mothers is discussed. PMID:21935658

2018-05-01

To examine risk factors for injury in pre-professional modern dancers. With prospectively designed screening and injury surveillance, we evaluated four risk factors as categorical predictors of injury: i) hypermobility; ii) dance technique motor-control; iii) muscle tightness; iv) previous injury. Screening and injury data of 180 students enrolled in a university modern dance program were reviewed over 4-yrs of training. Dancers were divided into 3-groups based on predictor scores. Dance exposure was based on hours of technique classes/wk. Negative binomial log-linear analyses were conducted with the four predictors, p < 0.05. Dancers with low and high Beighton scores were 1.43 and 1.22 times more likely to sustain injury than dancers with mid-range scores (p ≤ 0.03). Dancers with better technique (low or medium scores) were 0.86 and 0.63 times less likely to sustain injury (p = 0.013 and p < 0.001) compared to those with poor technique. Dancers with one or 2-4 tight muscles were 2.7 and 4.0 times more likely to sustain injury (p ≤ 0.046). Dancers who sustained 2-4 injuries in the previous year were 1.38 times more likely to sustain subsequent injury (p < 0.001). This contributes new information on the value of preseason screening. Dancers with these risk factors may benefit from prevention programs. Copyright © 2018 Elsevier Ltd. All rights reserved.

Are workplace health promotion programs effective at improving presenteeism in workers? A systematic review and best evidence synthesis of the literature.

Presenteeism is highly prevalent and costly to employers. It is defined as being present at work, but limited in some aspect of job performance by a health problem.Workplace health promotion (WHP) is a common strategy used to enhance on-the-job productivity. The primary objective is to determine if WHP programs are effective in improving presenteeism. The secondary objectives are to identify characteristics of successful programs and potential risk factors for presenteeism. The Cochrane Library, Medline, and other electronic databases were searched from 1990 to 2010. Reference lists were examined, key journals were hand-searched and experts were contacted. Included studies were original research that contained data on at least 20 participants (≥ 18 years of age), and examined the impacts of WHP programs implemented at the workplace. The Effective Public Health Practice Project Tool for Quantitative Studies was used to rate studies. 'Strong' and 'moderate' studies were abstracted into evidence tables, and a best evidence synthesis was performed. Interventions were deemed successful if they improved the outcome of interest. Their program components were identified, as were possible risk factors contributing to presenteeism. After 2,032 titles and abstracts were screened, 47 articles were reviewed, and 14 were accepted (4 strong and 10 moderate studies). These studies contained preliminary evidence for a positive effect of some WHP programs. Successful programs offered organizational leadership, health risk screening, individually tailored programs, and a supportive workplace culture. Potential risk factors contributing to presenteeism included being overweight, a poor diet, a lack of exercise, high stress, and poor relations with co-workers and management. This review is limited to English publications. A large number of reviewed studies (70%) were inadmissible due to issues of bias, thus limiting the amount of primary evidence. The uncertainties surrounding presenteeism measurement is of significant concern as a source of bias. The presenteeism literature is young and heterogeneous. There is preliminary evidence that some WHP programs can positively affect presenteeism and that certain risk factors are of importance. Future research would benefit from standard presenteeism metrics and studies conducted across a broad range of workplace settings.

It has been shown that organized screening decreases prostate cancer (PC) mortality, but the effect of opportunistic screening is largely unknown. To compare the ability to reduce PC mortality and the risk of overdiagnosis between organized and opportunistic screening. The Göteborg screening study invited 10 000 randomly selected men for prostate-specific antigen (PSA) testing every 2 yr since 1995, with a prostate biopsy recommended for men with PSA ≥2.5 ng/ml. The control group of 10 000 men not invited has been exposed to a previously reported increased rate of opportunistic PSA testing. Both groups were followed until December 31, 2012. Observed cumulative PC incidence and mortality rates in both groups were calculated using the actuarial method. Using historical data from 1990-1994 (pre-PSA era), we calculated expected PC incidence and mortality rates in the absence of any PSA testing. The number needed to invite (NNI) and the number needed to diagnose (NND) were calculated by comparing the expected versus observed incidence and mortality rates. At 18 yr, 1396 men were diagnosed with PC and 79 men died of PC in the screening group, compared to 962 and 122, respectively, in the control group. In the screening group, the observed cumulative PC incidence/mortality was 16%/0.98% compared to expected values of 6.8%/1.7%. The corresponding values for the control group were 11%/1.5% and 6.9%/1.7%. Organized screening was associated with an absolute PC-specific mortality reduction of 0.72% (95% confidence interval [CI] 0.50-0.94%) and relative risk reduction of 42% (95% CI 28-54%). There was an absolute reduction in PC deaths of 0.20% (95% CI -0.06% to 0.47%) and a relative risk reduction of 12% (95% CI -5 to 26%) associated with opportunistic PSA testing. NNI and NND were 139 (95% CI 107-200) and 13 for organized biennial screening and 493 (95% CI 213- -1563) and 23 for opportunistic screening. The extent of opportunistic screening could not be measured; incidence trends were used as a proxy. Organized screening reduces PC mortality but is associated with overdiagnosis. Opportunistic PSA testing had little if any effect on PC mortality and resulted in more overdiagnosis, with almost twice the number of men needed to be diagnosed to save one man from dying from PC compared to men offered an organized biennial screening program. Prostate-specific antigen (PSA) screening within the framework of an organized program seems more effective than unorganized screening. Copyright © 2014 European Association of Urology.

The authors present their analysis of screening methods used for early diagnostics of cancer of various localization and for detection of high-risk individuals. They offer a program of step-by-step screening that makes it possible to cover more population with prophylactic examination and to reduce the need for special examination methods. TG-test is a universal and the most informative blastomatous process indicator at any stage, including the preclinical one. The practical screening results double the revealing rate of oncopathology and allow for three-fold reduction in the diagnostic costs compared with standard methods of cancer diagnostics. The medical efficiency of the oncological screening is high; in one third of the examined patients a tumor is diagnosed at the preclinical stage.

Recruitment into diabetes prevention programs: what is the impact of errors in self-reported measures of obesity?

Error in self-reported measures of obesity has been frequently described, but the effect of self-reported error on recruitment into diabetes prevention programs is not well established. The aim of this study was to examine the effect of using self-reported obesity data from the Finnish diabetes risk score (FINDRISC) on recruitment into the Greater Green Triangle Diabetes Prevention Project (GGT DPP). The GGT DPP was a structured group-based lifestyle modification program delivered in primary health care settings in South-Eastern Australia. Between 2004-05, 850 FINDRISC forms were collected during recruitment for the GGT DPP. Eligible individuals, at moderate to high risk of developing diabetes, were invited to undertake baseline tests, including anthropometric measurements performed by specially trained nurses. In addition to errors in calculating total risk scores, accuracy of self-reported data (height, weight, waist circumference (WC) and Body Mass Index (BMI)) from FINDRISCs was compared with baseline data, with impact on participation eligibility presented. Overall, calculation errors impacted on eligibility in 18 cases (2.1%). Of n = 279 GGT DPP participants with measured data, errors (total score calculation, BMI or WC) in self-report were found in n = 90 (32.3%). These errors were equally likely to result in under- or over-reported risk. Under-reporting was more common in those reporting lower risk scores (Spearman-rho = -0.226, p-value < 0.001). However, underestimation resulted in only 6% of individuals at high risk of diabetes being incorrectly categorised as moderate or low risk of diabetes. Overall FINDRISC was found to be an effective tool to screen and recruit participants at moderate to high risk of diabetes, accurately categorising levels of overweight and obesity using self-report data. The results could be generalisable to other diabetes prevention programs using screening tools which include self-reported levels of obesity.

Cervical screening in HPV-vaccinated populations.

PubMed

Canfell, K

2018-06-01

Cervical screening with cytology has been the basis for substantial reductions in cervical cancer incidence and mortality in most high-income countries over the last few decades. More recently, there have been two key, parallel developments which have prompted a major re-consideration of cervical screening. The first is the emergence of evidence on the improved sensitivity of human papillomavirus (HPV) DNA testing compared to cytology, and the second is the large-scale deployment of prophylactic vaccination against HPV. A key challenge to be overcome before HPV screening could be introduced into national cervical screening programs was the specificity of an infection, for detection of precancerous lesions. This has been done in three ways: (1) by considering the appropriate age for starting HPV screening (30 years in unvaccinated populations and 25 years in populations with mature vaccination programs and high vaccine uptake) and the appropriate screening interval; (2) via development of clinical HPV tests, which are (by design) not as sensitive to low viral loads; and (3) by introducing effective triaging for HPV-positive women, which further risk-stratifies women before referral for diagnostic evaluation. This review discusses these major developments and describes how the benefits of HPV screening are being optimized in both unvaccinated and vaccinated populations.

Breast cancer is one of the most common cause of cancer mortality. Early detection through mammography screening could significantly reduce mortality from breast cancer. However, most of screening methods may consume large amount of resources. We propose a computational model, which is solely based on personal health information, for breast cancer risk assessment. Our model can be served as a pre-screening program in the low-cost setting. In our study, the data set, consisting of 3976 records, is collected from Taipei City Hospital starting from 2008.1.1 to 2008.12.31. Based on the dataset, we first apply the sampling techniques and dimension reduction method to preprocess the testing data. Then, we construct various kinds of classifiers (including basic classifiers, ensemble methods, and cost-sensitive methods) to predict the risk. The cost-sensitive method with random forest classifier is able to achieve recall (or sensitivity) as 100 %. At the recall of 100 %, the precision (positive predictive value, PPV), and specificity of cost-sensitive method with random forest classifier was 2.9 % and 14.87 %, respectively. In our study, we build a breast cancer risk assessment model by using the data mining techniques. Our model has the potential to be served as an assisting tool in the breast cancer screening.

To describe the cultural, social and gender features that determine attitudes to colorectal cancer screening in a target group of patients aged 50 to 69 years old in the primary health care setting. We performed a qualitative ethnographic study from a gender perspective. Participants consisted of men and women aged 50 to 69 years old in the Balearic Islands and Barcelona. Group discussion and a field diary were used. The key element was diagnosis at an early stage. Until recently, cancer was considered an incurable disease but is currently perceived as a serious health problem that can be cured if diagnosed promptly. The participants requested more information on cancer and felt they were at risk, mainly because of their age. Men tended to pay attention to symptoms while women tended to ignore them. Attitudes to colorectal cancer screening were generally positive, even to colonoscopy. Some barriers to screening were identified in women, such as a fear of having cancer. The opportunity for early diagnosis is the key element in promoting participation in a colorectal cancer screening program. Perceptions-and hence willingness to participate in screening-differ between men and women. Factors to be taken into account in the design of population-based colorectal cancer programs are health concerns in men and fear of a cancer diagnosis in women. Copyright © 2012 SESPAS.

Congenital hypothyroidism and phenylketonuria (PKU) are the most common cause for preventable mental retardation in infants worldwide. Timely diagnosis and treatment of these disorders can have lasting effects on the mental development of newborns. However, there are several problems at different stages of screening programs that along with imposing heavy costs can reduce the precision of the screening, increasing the chance of undiagnosed cases which in turn can have damaging consequences for the society. Therefore, given these problems and the importance of information systems in facilitating the management and improving the quality of health care the aim of this study was to improve the screening process of hypothyroidism and PKU in infants with the help of electronic resources. The current study is a qualitative, action research designed to improve the quality of screening, services, performance, implementation effectiveness, and management of hypothyroidism and PKU screening program in Isfahan province. To this end, web-based software was designed. Programming was carried out using Delphi.net software and used SQL Server 2008 for database management. Given the weaknesses, problems, and limitations of hypothyroidism and PKU screening program, and the importance of these diseases in a national scale, this study resulted in design of hypothyroidism and PKU screening software for infants in Isfahan province. The inputs and outputs of the software were designed in three levels including Health Care Centers in charge of the screening program, provincial reference lab, and health and treatment network of Isfahan province. Immediate registration of sample data at the time and location of sampling, providing the provincial reference Laboratory and Health Centers of different eparchies with the ability to instantly observe, monitor, and follow-up on the samples at any moment, online verification of samples by reference lab, creating a daily schedule for reference lab, and receiving of the results from analysis equipment; and entering the results into the database without the need for user input are among the features of this software. The implementation of hypothyroidism screening software led to an increase in the quality and efficiency of the screening program; minimized the risk of human error in the process and solved many of the previous limitations of the screening program which were the main goals for implementation of this software. The implementation of this software also resulted in improvement in precision and quality of services provided for these two diseases and better accuracy and precision for data inputs by providing the possibility of entering the sample data at the place and time of sampling which then resulted in the possibility of management based on precise data and also helped develop a comprehensive database and improved the satisfaction of service recipients.

Implementation of a generalized screening program for neonatal diseases must obey precise rules. The disease must be severe, recognizable at an early stage, amenable to an effective treatment, detectable with a non expensive and widely applicable test; it must also be a significant public health problem. Subjects with positive results must be offered immediate treatment or prevention. All screening programs must be regularly evaluated. In France, since 1978, a national screening program has been organized by a private association ("Association française pour le dépistage et la prévention des handicaps de l'enfant") and supervised by the "Caisse nationale d'assurance maladie" and "Direction Générale de la Sante". Five diseases are now included in the screening program: phenylketonuria, hypothyroidism, congenital adrenal hyperplasia, cystic fibrosis and sickle cell disease (the latter only in at-risk newborns). Toxoplasmosis is a particular problem because only the children of mothers who were not tested during the pregnancy or who seroconverted are screened. Neonatal screening for phenylketonuria and hypothyrodism is unanimously recommended. Screening for congenital adrenal hyperplasia is approved in most countries. Cases of sickle cell disease and cystic fibrosis are more complex because--not all children who carry the mutations develop severe forms;--there is no curative treatment;--parents may become anxious, even though the phenotype is sometimes mild or even asymptomatic. Supporters of screening stress the benefits of early diagnosis (which extends the life expectancy of these children, particularly in the case of sickle cell disease), the fact that it opens up the possibility of prenatal screening of future pregnancies, and the utility of informing heterozygous carriers identified by familial screening. Neonatal screening for other diseases is under discussion. Indeed, technical advances such as tandem mass spectrometry make it possible to detect about 50 diseases in a single run. In addition to issues of cost and organization, any increase in the number of screened diseases will raise ethical problems, such as how to inform parents of an incurable disease, a late-onset disease, or an entirely asymptomatic disorder. It is unanimously agreed that only Mendelian diseases should be screened for (excluding genetic polymorphisms). Analysis of the present situation suggests the following changes:--guidelines for choosing new diseases for neonatal screening should be updated;--all new screening programs should be tested locally before nationwide implementation;--an evaluation committee of paediatricians and epidemiologists should be created, and the children's long-term outcome should be studied;--the conditions in which heterozygous carriers are informed after familial investigations need to be precisely defined;--blood samples should be banked for epidemiological studies.

Objectives. We identified to what extent the Department of Defense postdeployment health surveillance program identifies at-risk drinking, alone or in conjunction with psychological comorbidities, and refers service members who screen positive for additional assessment or care. Methods. We completed a cross-sectional analysis of 333 803 US Army active duty members returning from Iraq or Afghanistan deployments in fiscal years 2008 to 2011 with a postdeployment health assessment. Alcohol measures included 2 based on self-report quantity-frequency items—at-risk drinking (positive Alcohol Use Disorders Identification Test alcohol consumption questions [AUDIT-C] screen) and severe alcohol problems (AUDIT-C score of 8 or higher)—and another based on the interviewing provider’s assessment. Results. Nearly 29% of US Army active duty members screened positive for at-risk drinking, and 5.6% had an AUDIT-C score of 8 or higher. Interviewing providers identified potential alcohol problems among only 61.8% of those screening positive for at-risk drinking and only 74.9% of those with AUDIT-C scores of 8 or higher. They referred for a follow-up visit to primary care or another setting only 29.2% of at-risk drinkers and only 35.9% of those with AUDIT-C scores of 8 or higher. Conclusions. This study identified missed opportunities for early intervention for at-risk drinking. Future research should evaluate the effect of early intervention on long-term outcomes. PMID:24922163

The risk-stratified osteoporosis strategy evaluation study (ROSE) is a randomized prospective population-based study investigating the effectiveness of a two-step screening program for osteoporosis in women. This paper reports the study design and baseline characteristics of the study population. 35,000 women aged 65-80 years were selected at random from the population in the Region of Southern Denmark and-before inclusion-randomized to either a screening group or a control group. As first step, a self-administered questionnaire regarding risk factors for osteoporosis based on FRAX(®) was issued to both groups. As second step, subjects in the screening group with a 10-year probability of major osteoporotic fractures ≥15% were offered a DXA scan. Patients diagnosed with osteoporosis from the DXA scan were advised to see their GP and discuss pharmaceutical treatment according to Danish National guidelines. The primary outcome is incident clinical fractures as evaluated through annual follow-up using the Danish National Patient Registry. The secondary outcomes are cost-effectiveness, participation rate, and patient preferences. 20,904 (60%) women participated and included in the baseline analyses (10,411 in screening and 10,949 in control group). The mean age was 71 years. As expected by randomization, the screening and control groups had similar baseline characteristics. Screening for osteoporosis is at present not evidence based according to the WHO screening criteria. The ROSE study is expected to provide knowledge of the effectiveness of a screening strategy that may be implemented in health care systems to prevent fractures.

Aim To investigate urban-rural differences in the distribution of risk factors for breast cancer. Methods We analyzed the data from the first round of the “Mamma” population based-screening program conducted in Croatia between 2007 and 2009 and self-reported questionnaire results for 924 patients with histologically verified breast cancer. Reproductive and anthropometric characteristics, family history of breast cancer, history of breast disease, and prior breast screening history were compared between participants from the city of Zagreb (n = 270) and participants from 13 counties with more than 50% of rural inhabitants (n = 654). Results The screen-detected breast cancer rate was 4.5 per 1000 mammographies in rural counties and 4.6 in the city of Zagreb, while the participation rate was 61% in rural counties and 59% in Zagreb. Women from Zagreb had significantly more characteristics associated with an increased risk of breast cancer (P < 0.001 in all cases): no pregnancies (15% vs 7%), late age of first pregnancy (≥30 years) (10% vs 4%), and the most recent mammogram conducted 2-3 years ago (32% vs 14%). Women from rural counties were more often obese (41% vs 28%) and had early age of first live birth (<20 years) (20% vs 7%, P < 0.001 for both). Conclusion Identification of rural-urban differences in mammography use and their causes at the population level can be useful in designing and implementing interventions targeted at the reduction of inequalities and modifiable risk factors.

Reduction of cancer-related disparities requires strategies that link medically underserved communities to preventive care. In this community-based participatory research project, a public library system brought together stakeholders to plan and undertake programs to address cancer screening and risk behavior. This study was implemented over 48 months in 20 large urban neighborhoods, selected to reach diverse communities disconnected from care. In each neighborhood, Cancer Action Councils were organized to conduct a comprehensive dynamic trial, an iterative process of program planning, implementation and evaluation. This process was phased into neighborhoods in random, stepped-wedge sequence. Population-level outcomes included self-reported screening adherence and smoking cessation, based on street intercept interviews. Event-history regressions (n = 9374) demonstrated that adherence outcomes were associated with program implementation, as were mediators such as awareness of screening programs and cancer information seeking. Findings varied by ethnicity, and were strongest among respondents born outside the U.S. or least engaged in care. This intervention impacted health behavior in diverse, underserved and vulnerable neighborhoods. It has been sustained as a routine library system program for several years after conclusion of grant support. In sum, participatory research with the public library system offers a flexible, scalable approach to reduce cancer health disparities. © Society for Community Research and Action 2017.

2013-01-01

Background and Aims Surveillance is an integral part of the colorectal cancer (CRC) screening process. We aimed to investigate inter-physician variation in follow-up procedures after screening colonoscopy in an opportunistic CRC screening program. Methods A historical cohort study in the German statutory health insurance system was conducted. 55,301 individuals who underwent screening colonoscopy in 2006 in Bavaria, Germany, and who were not diagnosed with CRC were included. Utilization of follow-up colonoscopies performed by the same physician (328 physicians overall) within 3 years was ascertained. Mixed effects logistic regression modelling was used to assess the effect of physicians and other potential predictors (screening result, age group, and sex) on re-utilization of colonoscopy. Physicians were grouped into quintiles according to individual effects estimated in a preliminary model. Predicted probabilities of follow-up colonoscopy by screening result and physician group were calculated. Results The observed rate of follow-up colonoscopy was 6.2% (95% confidence interval: 5.9-6.4%), 18.6% (17.8-19.4%), and 37.0% (35.5-38.4%) after negative colonoscopy, low-risk adenoma and high-risk adenoma detection, respectively. All considered predictors were statistically significantly associated with follow-up colonoscopy. The predicted probabilities of follow-up colonoscopy ranged from 1.7% (1.4-2.0%) to 11.0% (10.2-11.7%), from 7.3% (6.2-8.5%) to 35.1% (32.6-37.7%), and from 17.9% (15.5-20.6%) to 56.9% (53.5-60.3%) in the 1st quintile (lowest rates of follow-up) and 5th quintile (highest rates of follow-up) of physicians after negative colonoscopy, low-risk adenoma and high-risk adenoma detection, respectively. Conclusions This study suggests substantial inter-physician variation in follow-up habits after screening colonoscopy. Interventions, including organizational changes in CRC screening should be considered to reduce this variation. PMID:23874941

The United States (US) Army implemented a comprehensive HIV characterization program in 2012 following repeal of the Don't Ask, Don't Tell policy banning openly homosexual individuals from serving in the US military. Program staff administered a standardized case report form to soldiers newly diagnosed with HIV from 2012 to 2014 in compliance with new program requirements. The case report form documented sociodemographic, sexual, and other risk behavior information elicited from US Army regulation-mandated epidemiologic interviews at initial HIV notification. A majority of HIV-infected soldiers were male and of black/African American racial origin. In the HIV risk period, male soldiers commonly reported male-male sexual contact, civilian partners, online partner-seeking, unprotected anal sex, and expressed surprise at having a positive HIV result. Don't Ask, Don't Tell repeal allows for risk screening and reduction interventions targeting a newly identifiable risk category in the US Army. At-risk populations need to be identified and assessed for possible unmet health needs.

Despite rapid advances in medicine and beneficial lifestyle changes, the incidence and mortality rate of gynecologic carcinoma remains high worldwide. This paper presents the econometric model findings of the major drivers of breast cancer mortality among US women. The results have implications for public health policy formulation on disease incidence and the drivers of mortality risks. The research methodology is a fixed-effects GLS regression model of breast cancer mortality in US females age 25 and above, using 1990-1997 time-series data pooled across 50 US states and DC. The covariates are age, years schooled, family income, 'screening' mammography, insurance coverage types, race, and US census region. The regressions have strong explanatory powers. Finding education and income to be significantly and positively correlated with mortality supports the 'life in the fast lanes' hypothesis of Phelps. The policy of raising a woman's education at a given income appears more beneficial than raising her income at a given education level. The relatively higher mortality rate for Blacks suggests implementing culturally appropriate set of disease prevention and health promotion programs and policies. Mortality differs across insurance types with Medicaid the worst suggesting need for program reform. Mortality is greater for women ages 25-44 years, females 40-49 years who have had screening mammography, smokers, and residents of some US states. These findings suggest imposing more effective tobacco use control policies (e.g., imposing a special tobacco tax on adult smokers), creating a more tractable screening mammography surveillance system, and designing region-specific programs to cut breast cancer mortality risks.

Population-based breast cancer screening programs based on mammography must maintain a high level of quality, so the results must be constantly monitored. Although most authors consider that these programs have decreased the mortality due to breast cancer by about 30%, others claim that the mortality has decreased by only about 12% due to errors in the randomization of patients, because the rate of advanced tumors has hardly decreased and because adjuvant treatment also improves survival. Other criticisms focus on overdiagnosis and overtreatment. We believe that despite the unquestionable value of mammographic screening, we should be open to certain changes such as the stratification of patients by their level of risk and the introduction of complementary techniques like tomosynthesis, ultrasonography, and magnetic resonance imaging in selected cases.

2017-07-01

Background: This study examined the extent to which cancer programs demonstrated adherence to their own prescribed screening protocol, and whether adherence to that protocol was associated with medical service utilization. The hypothesis is that higher rates of service utilization are associated with lower rates of adherence to screening protocols. Methods: Oncology social workers at Commission on Cancer-accredited cancer programs reviewed electronic health records (EHRs) in their respective cancer programs during a 2-month period in 2014. Rates of overall adherence to a prescribed distress screening protocol were calculated based on documentation in the EHR that screening adherence and an appropriate clinical response had occurred. We examined documentation of emergency department (ED) use and hospitalization within 2 months after the screening visit. Results: Review of 8,409 EHRs across 55 cancer centers indicated that the overall adherence rate to screening protocols was 62.7%. The highest rates of adherence were observed in Community Cancer Programs (76.3%) and the lowest rates were in NCI-designated Cancer Centers (43.3%). Rates of medical service utilization were significantly higher than expected when overall protocol adherence was lacking. After controlling for patient and institutional characteristics, risk ratios for ED use (0.82) and hospitalization (0.81) suggest that when overall protocol adherence was documented, 18% to 19% fewer patients used these medical services. Conclusions: The observed associations between a mandated psychosocial care protocol and medical service utilization suggest opportunities for operational efficiencies and costs savings. Further investigations of protocol integrity, as well as the clinical care models by which psychosocial care is delivered, are warranted.

Abstract Background Depression is a prevalent, yet underdiagnosed, psychiatric disorder among patients with end-stage renal disease. Active case identification through routine screening is suggested; however, patient-related barriers may reduce the effectiveness of screening for, and treating, depression. This study aimed to explore the perceived barriers that limit patients from participating in screening and treatment programs for depression. Methods In a cross-sectional study of chronic maintenance hemodialysis patients, the Perceived Barriers to Psychological Treatment questionnaire, adapted to include screening, was used to measure perceived barriers. The two-item Patient Health Questionnaire was used to identify patients with depressive symptoms. Results Of 160 participants, 73.1% reported at least one barrier preventing them from participation [95% confidence interval (95% CI) 66.2–80.0%]. Patients with depressive symptoms were more likely to perceive at least one barrier to a screening program for depression compared with those without depressive symptoms (96% versus 68.9%, respectively; odds ratio = 10.8; 95% CI 1.4–82.8; P = 0.005). The association of the barrier scores with depressive symptoms remained significant after adjustment for patient’s characteristics. The most common barriers that patients expressed were concerns about the side effects of any antidepressant medications that may be prescribed (40%), concerns about having more medications (32%), feeling that the problem is not severe enough (23%) and perceiving no risk of depression (23%). Conclusions Negative perceptions about depression and its treatment among hemodialysis patients constitute an important barrier to identifying this condition and first need to be addressed before implementing a screening program in this population.

Invasive cervical cancer is today the fourth most common cancer of women in western civilization. Screening programs have led to a continuously decrease. Nevertheless, both screening and a positive test result are known to be associated with a negative psychological impact. Screening programs in European countries differ and thus psychological impact might as well. The aim of this study was to evaluate the psychological impact of women with an abnormal Pap smear in a German cohort. Between July 2013 and May 2014, a self-assessment questionnaire was distributed to 595 patients that were referred to a special clinic for cervical dysplasia for further evaluation of an abnormal Pap smear. Patients were recruited in five different centers. Most patients (45.9 %) were informed about the test result via phone call by their doctor. 68.8 % of the patients felt anxious and 26.3 % even felt panic. After having talked to their physician, 51.4 % of our cohort still felt worried and only 24.4 % felt reassured. Concerning disease management, 48.4 % underwent a control Pap smear in 6 months. The preferred information source was the physician (63.9 %). Compared to the results in other European countries, our study cohort showed differences concerning age distribution, patients living in a partnership, number of children and especially disease management. Cancer screening itself and abnormal test results have an impact on patient's feelings. To reduce the psychological impact, patients need to be better informed about the risks and benefits of cancer screening programs and in case of cervical cancer screening about the meaning of an abnormal test result. Our results underline the importance of a trustful physician-patient relationship in that matter.

This article discusses the prevailing Chinese belief systems that have bearings on the perception and practices of promoting resilience among children and youth in a major city in China. It briefly describes a huge social intervention program entitled "Understanding the Adolescent Project" to combat the problems among grade 7 students identified as adolescents at risk from 2001 to 2004 in Hong Kong Special Administrative Region. A critical review of the problems encountered by social workers in the delivery of the program is presented to support the move to provide the preventive program for grade 4 students with clinical symptoms on a screening tool for identification of at-risk status. Starting in 2005, a large-scale positive youth development program was being developed for all secondary one to three (grades 7 to 9) students. Encouraging results of the evaluation studies demonstrated the effectiveness of this new preventive program, entitled Positive Adolescent Training through Holistic Social Programs.

Cancer prevention: state of the art and future prospects.

Cancer imposes a heavy societal burden worldwide, in terms of both epidemiology and costs. The introduction of more sophisticated imaging and diagnostic techniques and advanced drugs that specifically target tumor cells is leading to increasingly expensive treatments, which may be affordable only for few patients. Prevention, and particularly primary prevention, is an effective way of addressing the challenging issue of cancer, since between a third and a half of cancers could be prevented on the basis of our current knowledge of risk factors. Moreover, prevention is cost-effective, its effects are not limited to high-risk subjects but extend to the entire population, and it is not dependent on socioeconomic status. Regulatory measures can have a broad impact, even on future generations; by empowering and educating subjects, promoting healthy behaviours and teaching self-care, they can trigger a virtuous cycle. In recent decades, oncology has shifted from being merely reactive to being proactive; this shift has led to the development of so-called "P4 medicine", where the 4 Ps stand for "preventive", "predictive", "personalized" and "participatory". Prevention programs are an important part of the effort to control cancer, as they are able to reduce both the incidence of cancer and mortality. For instance, screening for colorectal, breast and cervical cancer is reducing the burden of these common tumors. Anti-cancer vaccines, both prophylactic and therapeutic, constitute another important preventive tool. Although progress has been made in these areas, much remains to be done. With regard to screening programs, coverage could be increased by introducing new, more acceptable, less invasive tests, stratifying screening through correlation with anamnestic, clinical, radiological and genomic data (so-called "populationbased personalized cancer screening"), and exploiting new information and communication technologies, such as smartphone applications or personalized text messages (so-called "screening 2.0"). Advocacy and recommendations by physicians can also play a role, in that eligible subjects need to be able to discuss their doubts and their perceived psycho-social barriers. However, new screening initiatives should be implemented only after a careful health technology assessment has been performed within the framework of evidence-based medicine, organized screening programs have been strengthened and opportunistic or spontaneous programs have been limited. © Copyright by Pacini Editore SpA, Pisa, Italy.

Knowledge, Attitude, and Experience of Cervical Cancer and Screening among Sub-saharan African Female Students in a UK University

Ogbonna, Faith Sopuruchukwu

2017-01-01

Background: Cervical cancer is one of the major diseases that affect women of child bearing age. Its main cause is the human papilloma virus; although, other associated factors have been evidenced to increase its risk. Pap-smear screening and vaccination which has been shown to be successful in reducing the incidence and prevalence of the disease in developed countries, has been neglected in developing countries due to lack of knowledge, misconceptions, and cultural beliefs. Materials and Methods: A cross-sectional study involving only female Sub-Saharan Africa (SSA) students in a UK university setting. Results: One hundred and eighty-six (42%) African female students were recruited from the 442 SSA students attending one of the major Universities in the UK. Seventy-one (38.2%) of the students were aware of cervical screening, but only 20 (10.8%) reported having knowledge of cervical cancer. A small percentage of about 26.9% (50 Students) were already part of this screening program; although, 81 (43.5%) showed willingness to participate in future screening programs. More so, it was evident that student's perception was dependent on their experience of the disease (P = 000) just as their participation in screening program was dependent on their awareness level (P ≤ 0.01). Conclusion: Female African students from the SSA region have poor knowledge of the disease which influenced their attitude toward screening. More needs to be carried out to increase awareness and uptake of screening within the school environment as university setting provides a viable platform to promote healthy behavior. PMID:28300047

The trend of increasing numbers of patients with type 2 diabetes emphasizes the need for active screening of high-risk individuals and intensive lifestyle modification (LSM). The community-based Korean Diabetes Prevention Study (C-KDPS) is a randomized controlled clinical trial to prevent type 2 diabetes by intensive LSM using a web-based program. The two public healthcare centers in Korea are involved, and 420 subjects are being recruited for 6 months and will be followed up for 22 months. The participants are allocated randomly to intensive LSM (18 individual sessions for 24 weeks) and usual care (control group). The major goals of the C-KDPS lifestyle intervention program are: 1) a minimum of 5-7% loss of initial body weight in 6 months and maintenance of this weight loss, 2) increased physical activity (≥ 150 min/week of moderate intensity activity), 3) balanced healthy eating, and 4) quitting smoking and alcohol with stress management. The web-based program includes education contents, video files, visit schedules, and inter-communicable keeping track sites. Primary outcomes are the diagnoses of newly developed diabetes. A 75-g oral glucose tolerance test with hemoglobin A1c level determination and cardiovascular risk factor assessment is scheduled at 6, 12, 18, and 22 months. Active screening of high-risk individuals and an effective LSM program are an essential prerequisite for successful diabetes prevention. We hope that our C-KDPS program can reduce the incidence of newly developed type 2 diabetes and be implemented throughout the country, merging community-based public healthcare resources and a web-based system.

We determined the feasibility of abdominal aortic aneurysm (AAA) screening program led by family physicians in public primary healthcare setting using hand-held ultrasound device. The potential study population was 11,214 men aged ≥ 60 years attended by three urban, public primary healthcare centers. Participants were recruited by randomly-selected telephone calls. Ultrasound examinations were performed by four trained family physicians with a hand-held ultrasound device (Vscan®). AAA observed were verified by confirmatory imaging using standard ultrasound or computed tomography. Cardiovascular risk factors were determined. The prevalence of AAA was computed as the sum of previously-known aneurysms, aneurysms detected by the screening program and model-based estimated undiagnosed aneurysms. We screened 1,010 men, with mean age of 71.3 (SD 6.9) years; 995 (98.5%) men had normal aortas and 15 (1.5%) had AAA on Vscan®. Eleven out of 14 AAA-cases (78.6%) had AAA on confirmatory imaging (one patient died). The total prevalence of AAA was 2.49% (95%CI 2.20 to 2.78). The median aortic diameter at diagnosis was 3.5 cm in screened patients and 4.7 cm (p<0.001) in patients in whom AAA was diagnosed incidentally. Multivariate logistic regression analysis identified coronary heart disease (OR = 4.6, 95%CI 1.3 to 15.9) as the independent factor with the highest odds ratio. A screening program led by trained family physicians using hand-held ultrasound was a feasible, safe and reliable tool for the early detection of AAA. PMID:28453577

Background: Cardiovascular disease is a major health concern around the world. Objective: To assess the outcomes and feasibility of a pharmacy-based cardiovascular screening in an urban referral community pharmacy in Iran. Methods: A cross sectional study was conducted in a referral community pharmacy. Subjects aged between 30-75 years without previous diagnose of cardiovascular disease or diabetes were screened. Measurement of all major cardiovascular risk factors, exercise habits, medical conditions, medications, and family history were investigated. Framingham risk score was calculated and high risk individuals were given a clinical summary sheet signed by a clinical pharmacist and were encouraged to follow up with their physician. Subjects were contacted one month after the recruitment period and their adherence to the follow up recommendation was recorded. Results: Data from 287 participants were analyzed and 146 were referred due to at least one abnormal laboratory test. The results showed 26 patients with cardiovascular disease risk greater than 20%, 32 high systolic blood pressure, 22 high diastolic blood pressures, 50 high total cholesterol levels, 108 low HDL-C levels, and 22 abnormal blood glucose levels. Approximately half of the individuals who received a follow up recommendation had made an appointment with their physician. Overall, 15.9% of the individuals received medications and 15.9% received appropriate advice for risk factor modification. Moreover, 7.5% were under evaluation by a physician. Conclusion: A screening program in a community pharmacy has the potential to identify patients with elevated cardiovascular risk factor. A plan for increased patient adherence to follow up recommendations is required. PMID:28690693

Objectives: To determine the prevalence of uncorrected refractive errors (URE) among children 3-10 years and to affirm the necessity of a national school-based visual screening program for school-aged children. Methods: This retrospective cross-sectional study was conducted in Medina, Saudi Arabia in 2015. Children were selected through a multistage stratified random sampling from 8 kindergarten and 8 primary schools. Those included were screened to diagnose UREs using a visual acuity chart and an auto refractometer according to American guidelines. The prevalence and types of UREs were estimated. Results: Of the 2121 children enumerated, 1893 were examined, yielding a response rate of 89.3%. The prevalence of UREs was 34.9% (95% CI = 32.8%-37.1%), with significant differences in different age groups. The prevalence of astigmatism (25.3%) was higher compared to that of anisometropia (7.4%), hypermetropia (1.5%), and myopia (0.7%). Risk of uncorrected refractive error was positively associated with age, and this was noted in astigmatism, myopia, and anisometropia. In addition, the risk of hypermetropia was associated with boys and that of myopia was associated with girls. Conclusions: The prevalence of UREs, particularly astigmatism, was high among children aged 3-10 years in Medina, with significant age differences. Vision screening programs targeting kindergarten and primary schoolchildren are crucial to lessen the risk of preventable visual impairment due to UREs. PMID:28762432

In addition, the risk of hypermetropia was associated with boys and that of myopia was associated with girls. Conclusions: The prevalence of UREs, particularly astigmatism, was high among children aged 3-10 years in Medina, with significant age differences. Vision screening programs targeting kindergarten and primary schoolchildren are crucial to lessen the risk of preventable visual impairment due to UREs.

A goal when designing the Physical Therapy Program at Lebanon Valley College (LVC) was to maximize vertical and horizontal integration of course content related to (a) medical Spanish, (b) geriatrics, and (c) health promotion through a service learning engagement. Seventeen Doctor of Physical Therapy students from LVC participated in a fall risk screening at a local senior center in a Spanish-speaking neighborhood. The screen included the single leg stance, timed-up-and-go (TUG), and functional reach tests. The students screened 30 participants over a 3-hour time period. Following the screening event, students were asked to reflect on their experience. Reflections revealed that the activity supported integration of concurrent didactic course material and Core Values, reinforced cultural issues presented the previous year, and convinced students that physical therapists have a distinct and important role in primary and secondary prevention in meeting the needs of the Spanish-speaking elderly community.

From 2003 to 2012, the Philadelphia High School STD Screening Program screened 126,053 students, identifying 8089 Chlamydia trachomatis (CT)/Neisseria gonorrhoeae (GC) infections. We examined sociodemographic and behavioral factors associated with CT/GC diagnoses among a sample of this high-risk population. Standardized interviews were given to infected students receiving in-school CT/GC treatment (2009-2012) and to uninfected students calling for results (2011-2012). Sex-stratified multivariable logistic models were created to examine factors independently associated with a CT/GC diagnosis. A simple risk index was developed using variables significant on multivariable analysis. A total of 1489 positive and 318 negative students were interviewed. Independent factors associated with a GC/CT diagnosis among females were black race (adjusted odds ratio [AOR], 2.27; confidence interval, 1.12-4.58), history of arrest (AOR, 2.26; 1.22-4.21), higher partner number (AOR, 1.75; 1.05-2.91), meeting partners in own neighborhood (AOR, 1.92; 1.29-2.86), and meeting partners in venues other than own school, neighborhood, or through friends ("all other"; AOR, 9.44; 3.70-24.09). For males, factors included early sexual debut (AOR, 1.99; 1.21-3.26) and meeting partners at "all other" venues (AOR, 2.76; 1.2-6.4); meeting through friends was protective (AOR, 0.63; 0.41-0.96). Meeting partners at own school was protective for both sexes (males: AOR, 0.33; 0.20-0.55; females: AOR, 0.65; 0.44-0.96). Although factors associated with a GC/CT infection differed between males and females in our sample, partner meeting place was associated with infection for both sexes. School-based screening programs could use this information to target high-risk students for effective interventions.

Purpose Men with a family history (FH) of prostate cancer (PCA) and African American (AA) men are at higher risk for PCA. Recruitment and retention of these high-risk men into early detection programs has been challenging. We report a comprehensive analysis on recruitment methods, show rates, and participant factors from the Prostate Cancer Risk Assessment Program (PRAP), which is a prospective, longitudinal PCA screening study. Materials and Methods Men 35–69 years are eligible if they have a FH of PCA, are AA, or have a BRCA1/2 mutation. Recruitment methods were analyzed with respect to participant demographics and show to the first PRAP appointment using standard statistical methods Results Out of 707 men recruited, 64.9% showed to the initial PRAP appointment. More individuals were recruited via radio than from referral or other methods (χ2 = 298.13, p < .0001). Men recruited via radio were more likely to be AA (p<0.001), less educated (p=0.003), not married or partnered (p=0.007), and have no FH of PCA (p<0.001). Men recruited via referrals had higher incomes (p=0.007). Men recruited via referral were more likely to attend their initial PRAP visit than those recruited by radio or other methods (χ2 = 27.08, p < .0001). Conclusions This comprehensive analysis finds that radio leads to higher recruitment of AA men with lower socioeconomic status. However, these are the high-risk men that have lower show rates for PCA screening. Targeted motivational measures need to be studied to improve show rates for PCA risk assessment for these high-risk men. PMID:19758657

Counterpoint: implementing population genetic screening for Lynch Syndrome among newly diagnosed colorectal cancer patients--will the ends justify the means?

PubMed

Hall, Michael J

2010-05-01

Inherited mutations in 1 of 4 known mismatch repair genes (MLH1, MSH2, MSH6, PMS2) are associated with various cancer risks collectively referred to as Lynch syndrome. Roughly 3 of every 100 new colorectal cancers (CRCs) have an underlying Lynch mutation. Tumor-based screening for Lynch among all patients with newly diagnosed CRC could theoretically improve the ability to identify Lynch and prevent cancer among at-risk family members, but the patient-level and social implications of this approach must be carefully considered before adopting this strategy. Poorly addressed issues include the role/timing of informed consent for testing, access and cost barriers associated with genetic counseling and DNA testing, psychosocial burdens to the thousands of middle-aged and elderly patients with CRC coping with surgical and chemotherapy treatments and poor prognosis, the need for providers to warn third-party relatives of risk for Lynch syndrome, limited effectiveness of screening, and the cost burden to society when poor DNA testing uptake, test limitations, and modest screening compliance are considered. Diverse barriers to the success of a population-based Lynch screening program in the United States remain (e.g., clinical resource needs, financial limitations, clinical expertise gaps, educational deficits). Data supporting clinical efficacy (feasibility) and effectiveness (real-life performance) are critical before important policy changes are adopted, especially where issues of hereditary cancer risk and genetic privacy are involved.

2014-01-01

We summarized and appraised evidence regarding HIV prevention interventions for adults with criminal justice involvement. We included randomized and quasi-randomized controlled trials that evaluated an HIV prevention intervention, enrolled participants with histories of criminal justice involvement, and reported biological or behavioral outcomes. We used Cochrane methods to screen 32 271 citations from 16 databases and gray literature. We included 37 trials enrolling n = 12 629 participants. Interventions were 27 psychosocial, 7 opioid substitution therapy, and 3 HIV-testing programs. Eleven programs significantly reduced sexual risk taking, 4 reduced injection drug risks, and 4 increased testing. Numerous interventions may reduce HIV-related risks among adults with criminal justice involvement. Future research should consider process evaluations, programs involving partners or families, and interventions integrating biomedical, psychosocial, and structural approaches. PMID:25211725

Before enacting health insurance reform in 2006, Massachusetts provided free breast, cervical cancer, and cardiovascular risk screening for low-income uninsured women through a federally subsidized program called the Women's Health Network (WHN). This article examines whether, as women transitioned to insurance to pay for screening tests after health reform legislation was passed, cancer and cardiovascular disease screening changed among WHN participants between 2004 and 2010. We examined claims data from the Massachusetts health insurance exchange and chart review data to measure utilization of mammography, Pap smear, and blood pressure screening among WHN participants in five community health centers in greater Boston. We conducted a longitudinal analysis, by insurance type, using generalized estimating equations to examine the likelihood of screening at recommended intervals in the postreform period compared to the prereform period. Pre- and postreform, we found a high prevalence of recommended mammography (86% vs. 88%), Pap smear (88% vs. 89%), and blood pressure screening (87% vs. 91%) that was similar or improved for most women postreform. Screening use differed by insurance type. Recommended mammography screening was statistically significantly increased among women with state-subsidized private insurance (odds ratio [OR] 1.58, p<0.05). Women with unsubsidized private insurance or Medicare had decreased Pap smear use postreform. Although screening prevalence was high, 31% of women required state safety-net funds to pay for screening tests. Our results suggest a continued need for safety-net programs to support preventive screening among low-income women after implementation of healthcare reform.

Qualitative comparative analysis (QCA) was developed over 25 years ago to bridge the qualitative and quantitative research gap. Upon searching PubMed and the Journal of Mixed Methods Research, this review identified 30 original research studies that utilized QCA. Perceptions that QCA is complex and provides few relative advantages over other methods may be limiting QCA adoption. Thus, to overcome these perceptions, this article demonstrates how to perform QCA using data from fifteen institutions that implemented universal tumor screening (UTS) programs to identify patients at high risk for hereditary colorectal cancer. In this example, QCA revealed a combination of conditions unique to effective UTS programs. Results informed additional research and provided a model for improving patient follow-through after a positive screen. PMID:27429602

Vancor, Emily; Shapiro, Eugene D; Loyal, Jaspreet

2018-01-24

Congenital cytomegalovirus (CMV) infection is a major cause of sensorineural hearing loss. By law, newborns in Connecticut who fail newborn hearing screening are tested for infection with CMV. This targeted screening is controversial, because most children with congenital CMV infection are asymptomatic, and CMV-related hearing loss can have a delayed onset. Our hospital uses a saliva polymerase chain reaction (PCR) assay (confirmed by a urine PCR assay) to detect CMV. Here, we report the results of the first year of our screening program. We reviewed the medical records of newborns in the Yale New Haven Health System who failed the newborn hearing screening test between January 1 and December 31, 2016. Of 10964 newborns, 171 failed newborn hearing screening, and 3 of these newborns had positive saliva CMV PCR test results. Of these 3 newborns, 2 had positive results on the confirmatory test (for 1 of them the confirmatory test was not performed until the infant was 10 weeks old), and 1 had a negative result on the confirmatory test. Three additional newborns with congenital CMV infection were tested because of clinical indications (1 for ventriculomegaly on prenatal ultrasound and 2 for CMV infection of the mother). Results of audiology follow-up were available for 149 (87.1%) of the 171 newborns who failed newborn hearing screening; 127 (85.2%) had normal results. Our targeted screening program for congenital CMV infection had a low yield. Consideration should be given to other strategies for identifying children at risk of hearing loss as a result of congenital CMV infection. © The Author(s) 2018.

Approximately 16% of the estimated 1.1 million persons living with human immunodeficiency virus (HIV) in the United States are unaware of their infection and thus unable to benefit from effective treatment that improves health and reduces transmission risk. Since 2006, CDC has recommended that health-care providers screen for HIV all patients aged 13-64 years unless prevalence of undiagnosed HIV infection in their patients has been documented to be <0.1%. This report describes novel HIV screening programs at the Urban Health Plan (UHP), Inc. in New York City and the Interim Louisiana Hospital (ILH) in New Orleans. Data were provided by the two programs. UHP screened a monthly average of 986 patients for HIV during January 2011-September 2013. Of the 32,534 patients screened, 148 (0.45%) tested HIV-positive, of whom 147 (99%) received their test result and 43 (29%) were newly diagnosed. None of the 148 patients with HIV infection were previously receiving medical care, and 120 (81%) were linked to HIV medical care. The ILH emergency department (ED) and the urgent-care center (UCC) screened a monthly average of 1,323 patients from mid-March to December 2013. Of the 12,568 patients screened, 102 (0.81%) tested HIV-positive, of whom 100 (98%) received their test result, 77 (75%) were newly diagnosed, and five (5%) had acute HIV infection. Linkage to HIV medical care was successful for 67 (74%) of 91 patients not already in care. Routine HIV screening identified patients with new and previously diagnosed HIV infection and facilitated their linkage to medical care. The two HIV screening programs highlighted in this report can serve as models that could be adapted by other health-care settings.

The practicable and effective methods for residual risk assessment on transfusion-transmitted disease was to establish the mathematic models. Based on the characteristics of the repeat donors which donated their blood on a regular base, a model of sero-conversion during the interval of donations was established to assess the incidence of the repeat donors. Based on the characteristics of the prevalence in the population, a model of 'prevalence increased with the age of the donor' was established to assess the incidence of those first-time donors. And based on the impact of the windows period through blood screening program, a model of residual risk associated with the incidence and the length of the windows period was established to assess the residual risk of blood transfusion. In this paper, above said 3 kinds of mathematic models were jointly applied to assess the residual risk of hepatitis C virus (HCV) which was transmitted through blood transfusion in Shanghai, based on data from the routine blood collection and screening program. All the anti-HCV unqualified blood donations were confirmed before assessment. Results showed that the residual risk of HCV transmitted through blood transfusion during Jan. 1(st), 2007 to Dec. 31(st), 2008 in Shanghai was 1:101 000. Data showed that the results of residual risk assessment with mathematic models was valuable. The residual risk of transfusion-transmitted HCV in Shanghai was at a safe level, according to the results in this paper.

Background Childhood obesity has emerged as a public health concern in Canada. It has been suggested that excessive screen viewing (i.e., television, computer, video) is a major factor contributing to the increased risk of obesity in children. Exploring young children’s experiences with this modifiable behavior may be beneficial to the creation of a multifaceted program aimed at the primary prevention of obesity. Objectives To seek parents’ perceptions and insights pertaining to their preschoolers’ screen-viewing behaviors. Methods This qualitative study targeted a heterogeneous sample of parents with children aged 2.5 to 5 years. Two experienced moderators using a semistructured interview guide conducted the ten focus groups between September and November 2003. All focus groups were audio-recorded and transcribed verbatim. In fall 2003 to spring 2004, inductive content analysis was conducted independently by a minimum of two qualitative researchers. Results Many parents were not concerned with the amount of screen viewing their children engaged in, although the content of what was on the screen was of particular interest to them. Very few parents seemed to appreciate the linkage between preschoolers’ screen-viewing habits and their potential risk for obesity. Conclusions Public health interventions are needed to increase parents’ awareness with respect to the harmful effects of excessive screen viewing in preschoolers. PMID:16005808

Screening, Brief Intervention and Referral to Treatment (SBIRT) is a comprehensive, integrated, public health approach to the delivery of services to those at risk for the adverse consequences of alcohol and other drug use, and for those with probable substance use disorders. Research on successful SBIRT implementation has lagged behind studies of efficacy and effectiveness. This paper (1) outlines a conceptual framework, the SBIRT Program Matrix, to guide implementation research and program evaluation and (2) specifies potential implementation outcomes. Overview and narrative description of the SBIRT Program Matrix. The SBIRT Program Matrix has five components, each of which includes multiple elements: SBIRT services; performance sites; provider attributes; patient/client populations; and management structure and activities. Implementation outcomes include program adoption, acceptability, appropriateness, feasibility, fidelity, costs, penetration, sustainability, service provision and grant compliance. The Screening, Brief Intervention and Referral to Treatment Program Matrix provides a template for identifying, classifying and organizing the naturally occurring commonalities and variations within and across SBIRT programs, and for investigating which variables are associated with implementation success and, ultimately, with treatment outcomes and other impacts. © 2017 Society for the Study of Addiction.

Prostate cancer disproportionately affects Black men, who may also encounter barriers to participation in prostate cancer risk assessment. The Prostate Risk, Education and Assessment in the Community with Help (REACH) project was a community-based extension of a comprehensive prostate cancer risk assessment program at a comprehensive cancer center. The goals of the REACH project were the following: (1) establish a community prostate cancer risk assessment clinic, (2) conduct targeted recruitment, and (3) provide navigation services including follow-up for uninsured men. Key implementation steps included the following: (1) choosing a clinic site, (2) establishing patient access procedures, (3) establishing navigator services, (4) developing subsidy fund use guidelines, and (5) designing recruitment and promotion. Through community-based promotion, 64 men inquired about the program and 26 (41 %) participated. Of those screened, 46 % had abnormal results, and 2 men were diagnosed with prostate cancer. Here, we describe a unique demonstration project to implement a comprehensive prostate cancer risk assessment program in an underserved Black community and describe successes and challenges to inform future efforts to promote access to underserved men.

[Chances and risks of prevention in elderly people for the three major cancers: breast-, prostate- and colorectal cancers].

PubMed

Kolb, G F

2006-06-01

The big three, breast cancer (BC), prostate cancer (PC) and colorectal carcinoma are the most frequent malignancies world wide and also typical tumors of advanced age. Therefore the question to screen and how to screen for these tumors in the elderly is the main question for reduction of the total cancer burden and mortality in all western countries. BREAST CANCER (BC): The age related risk of BC increases from 1 : 2,500 at age 30+ to > 1 : 10 at age 80. Nevertheless, most of the national BC-Screening-Programs stop at age 60 or earlier. Therefore the majority of all advanced i. e. T (4) stages of BC are found in women age > 60. Frequently it is suggested that age related comorbidity should eliminate the benefit of treatment. Recently two longitudinal studies have clearly shown that correct standard treatment is as effective in elderly as in younger individuals. Mammography (MG) has been shown to reduce mortality of BC significantly with best results for specificity and sensitivity at age 70+. PROSTATE CANCER (PC): The screening situation of PC is quite different to BC, because risk profiles are poorly defined and the benefit of radical prostatectomy is not clearly demonstrated in the early non symptomatic stages of PC. At the other side watchful waiting leads to an elevated frequency of incontinence and enuresis as well. Two studies are now under progress and may possibly change the situation; but the final results are expected 2005-2008 at the earliest. Therefore an assisted individual decision making is the only recommendation at this time. COLORECTAL CANCER (CC): Risk groups are clearly defined. Risk of the elderly (> 60) is the average risk. The incidence increases from < 50/10 (5) to more than 500 at age 75+(male) and 500 (female). When to start and when to stop screening? Experts give the advice to begin at age 50 and to end at age 80; but this is not really evidence based. There are several unanswered questions and open problems: we are not exactly informed about complication rates of colonoscopy during the screening programs. There is a lack of data according accuracy of barium enema, virtual colonoscopy and genetic stool test in comparison to colonoscopy in combination with fecal occult blood test (FOBT). And adherence to screening is not well documented among informed patients. However, effectiveness of CC-screening (FOBT alone or in combination with colonoscopy) has been documented in three high randomised trials which have shown a disease specific mortality reduction of 15-33 % over a period of 8-13 years. But it must be clear that the economic resources must be mobilised individually or by insurance: offering the testing of only FOBT for ten years to one thousand persons can save one life.

The Mobile Geriatric Team (MGT) is part of the Geriatric Care Program and aims to provide interdisciplinary geriatric expertise to other professionals for old patients hospitalized outside geriatric department. Our hospital has a MGT since 2008. Our objective is to retrospectively describe the population of patients of 75 years and older hospitalized outside the geriatric ward and screened for the risk of functional decline by the MGT between 1 October 2009 and 30 September 2011. We recorded the risk of functional decline, as indicated by the Identification of Senior At Risk score (ISAR) performed within 48 h after admission, place of living, discharge destination, Mini Mental State Examination (MMSE) and Geriatric Depression Scale (GDS) scores. In two years, 1.568 patients > or = 75 Y were screened with the ISAR score (mean age 82.5 Y, 60.7% of women). We identified 833 patients with a high-risk of functional decline (ISAR > or = 3). The majority of high-risk subjects (78%) were living at home before hospitalization and 58.7% returned home after discharge. Depression and cognitive impairment were identified among respectively 41% and 59% of high-risk subjects. Only 128 patients were admitted for fall. Most of the faller patients were living at home prior hospitalization and had an ISAR score > or = 3. The MGT allowed identifying many patients > or = 75 Y living at home and presenting with high-risk of functional decline and geriatric syndromes, confirming that good screening procedures are necessary to optimize management of hospitalized olders. Most of faller patients have an ISAR score > or = 3 and should benefit a comprehensive geriatric assessment.

To evaluate improvement of medical student knowledge of head and neck cancer (HNC) through participation in HNC screening fairs run by medical students. Prospective cohort study of surveys assessing medical students' knowledge of HNC before and after volunteering at screening fairs. Four screening fairs held at the University of Miami Miller School of Medicine during Oral, Head and Neck Cancer Awareness Week. Medical student screening fair volunteers. Four HNC screening fairs were organized by medical student volunteers. All students completed a preevent survey assessing baseline knowledge and participated in an otolaryngologist-led training session about HNC and the screening examination. During the screening events, students educated guests about HNC and performed physician-guided history and physical examinations. Finally, students completed identical surveys 1 week and 3 months after the event. Thirty-four (n = 34) students completed the preevent surveys. At baseline, 59%, 44%, and 24% named tobacco, alcohol, and human papilloma virus as risk factors, compared with 84%, 81%, and 69% on 3 month follow-up, respectively. Out of 6 analyzed questions, the median total number of correctly answered questions improved from 2 on pretest to 5 at 3 months (P < .0001). Volunteer participation in a HNC screening program improves medical students' knowledge of HNC risk factors and symptoms. This innovative approach to students' education via participation and organization of screening events is a useful method of improving their HNC knowledge. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Annual chest computed tomography (CT) can decrease lung cancer mortality in high-risk individuals. Patient navigation improves cancer screening rates in underserved populations. Randomized controlled trial was conducted from February 2016 to January 2017 to evaluate the impact of a patient navigation program on lung cancer screening (LCS) among current smokers in five community health centers (CHCs) affiliated with an academic primary care network. We randomized 1200 smokers aged 55-77 years to intervention (n = 400) or usual care (n = 800). Navigators contacted patients to determine LCS eligibility, introduce shared decision making about screening, schedule appointments with primary care physicians (PCPs), and help overcome barriers to obtaining screening and follow-up. Control patients received usual care. The main outcome was the proportion of patients who had any chest CT. Secondary outcomes were the proportion of patients contacted, proportion receiving LCS CTs, screening results and number of lung cancers diagnosed. Of the 400 intervention patients, 335 were contacted and 76 refused participation. Of the 259 participants, 124 (48%) were ineligible for screening; 119 had smoked <30 pack-years, and five had competing comorbidities. Among the 135 eligible participants in the intervention group, 124 (92%) had any chest CT performed. In intention-to-treat analyses, 124 intervention patients (31%) had any chest CT versus 138 control patients (17.3%, P < 0.001). LCS CTs were performed in 94 intervention patients (23.5%) versus 69 controls (8.6%, P < 0.001). A total of 20% of screened patients required follow-up. Lung cancer was diagnosed in eight intervention (2%) and four control (0.5%) patients. A patient navigation program implemented in CHCs significantly increased LCS among high-risk current smokers. © 2018 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

This study reports the kin relationship and risk characteristics of family members who chose to participate in the Kin KeeperSM cancer prevention intervention, delivered by community health workers (CHWs) via existing community programs. African American, Latina, and Arab family members reported risk factors for inadequate screening, including comorbid health conditions and inadequate breast or cervical cancer literacy. CHW programs can be leveraged to reach underserved families with cancer preventive interventions. PMID:27634780

To survey the acceptance and willingness-to-pay for colorectal cancer colonoscopy screening among high risk populations in urban China. From 2012 to 2013, a Cancer Screening Program in Urban China (CanSPUC) was initiated in 9 provinces, the current survey was conducted among those participants who were evaluated as "high risk for colorectal cancer" by a risk-factor-evaluation-model (community-based) and then went through a colonoscopy screening procedure (hospital-based). All the data were obtained through a questionnaire-based interview (face-to-face or self-completed), mainly focusing on the acceptance and willingness-to-pay of the participants for colorectal colonoscopy screening. The current analysis included a total of 1 624 participants, with an median age of 55.0 years (P25 = 49.0, P75 = 61.0 years) and an annual income per capita of 17 thousand (range: 10-25 thousand) Chinese Yuan (CNY), 42.8% (695/1 624) of whom were males. Of all the participants, 87.0% (1 414/1 624) could totally or substantially accept the colonoscopy screening, particularly in those at higher education level (junior high school: OR = 0.34, 95% CI: 0.22-0.52; high school OR = 0.41, 95% CI: 0.26-0.66; college or over OR = 0.35, 95% CI: 0.20-0.59). Of all the participants, 13.0% (210/1 624) could not or hardly accept it, particularly in those with older age (60-69 years) (OR = 1.48, 95% CI: 1.06-2.07), not in marriage (OR = 2.15, 95% CI: 1.25-3.70) or with family member(s) to raise (OR = 1.60, 95% CI: 1.17-2.20). 1 388 (85.5%) of all the participants had willingness-to-pay for a long-term colonoscopy screening service, particularly in those working in public (OR = 0.61, 95% CI: 0.44-0.84) or enterprise sectors (OR = 0.60, 95% CI: 0.38-0.94), but 82.3% (1 141/1 386) of whom would only pay less than 100 CNY; 14.5% (236/1 624) of total had no willingness-to-pay, particularly in those living in areas with moderate (OR = 4.08, 95% CI: 2.75-6.33) or high GDP per capita (OR = 3.26, 95% CI: 2.11-4.92), or with an absence of willingness-to-pay for colonoscopy screening (OR = 3.98, 95% CI: 2.81-5.65). Although a larger community-based colorectal cancer screening program was warranted to examine the extrapolation of these findings, it suggested that the acceptance for colorectal cancer colonoscopy screening among the selected high-risk populations was considerable. The willing-to-pay was relatively high but the amount of payment was limited, the indicated subgroups with potentially less acceptance or willingness need to be more focused in the future to reach a higher participation rate. The data will also be informative in integrating the screening service into the local health insurance system.

Financial Incentives, Workplace Wellness Program Participation, and Utilization of Health Care Services and Spending.

This paper analyzes data from a large employer that enhanced financial incentives to encourage participation in its workplace wellness programs. It examines, first, the effect of financial incentives on wellness program participation, and second, it estimates the impact of wellness program participation on utilization of health care services and spending. The Patient Protection and Affordable Care Act of 2010 (PPACA) allows employers to provide financial incentives of as much as 30 percent of the total cost of coverage when tied to participation in a wellness program. Participation in health risk assessments (HRAs) increased by 50 percentage points among members of unions that bargained in the incentive, and increased 22 percentage points among non-union employees. Participation in the biometric screening program increased 55 percentage points when financial incentives were provided. Biometric screenings led to an average increase of 0.31 annual prescription drug fills, with related spending higher by $56 per member per year. Otherwise, no significant effects of participation in HRAs or biometric screenings on utilization of health care services and spending were found. The largest increase in medication utilization as a result of biometric screening was for statins, which are widely used to treat high cholesterol. This therapeutic class accounted for one-sixth of the overall increase in prescription drug utilization. Second were antidepressants, followed by ACE inhibitors (for hypertension), and thyroid hormones (for hypothyroidism). Biometric screening also led to significantly higher utilization of biologic response modifiers and immunosuppressants. These specialty medications are used to treat autoimmune diseases, such as rheumatoid arthritis and multiple sclerosis, and are relatively expensive compared with non-specialty medications. The added spending associated with the combined increase in fills of 0.02 was $27 per member per year--about one-half of the overall increase in prescription drug spending from those who participated in biometric screenings.

Currently, noninvasive prenatal testing (NIPT) is only recommended in high-risk women following conventional Down syndrome (DS) screening, and it has not yet been included in the Australian DS screening program. To evaluate the cost-effectiveness of different strategies of NIPT for DS screening in comparison with current practice. A decision-analytic approach modelled a theoretical cohort of 300,000 singleton pregnancies. The strategies compared were the following: current practice, NIPT as a second-tier investigation, NIPT only in women >35 years, NIPT only in women >40 years and NIPT for all women. The direct costs (low and high estimates) were derived using both health system costs and patient out-of-pocket expenses. The number of DS cases detected and procedure-related losses (PRL) were compared between strategies. The incremental cost per case detected was the primary measure of cost-effectiveness. Universal NIPT costs an additional $134,636,832 compared with current practice, but detects 123 more DS cases (at an incremental cost of $1,094,608 per case) and avoids 90 PRL. NIPT for women >40 years was the most cost-effective strategy, costing an incremental $81,199 per additional DS case detected and avoiding 95 PRL. The cost of NIPT needs to decrease significantly if it is to replace current practice on a purely cost-effectiveness basis. However, it may be beneficial to use NIPT as first-line screening in selected high-risk patients. Further evaluation is needed to consider the longer-term costs and benefits of screening. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Mitigating Thermal Runaway Risk in Lithium Ion Batteries

NASA Technical Reports Server (NTRS)

Darcy, Eric; Jeevarajan, Judy; Russell, Samuel

2014-01-01

The JSC/NESC team has successfully demonstrated Thermal Runaway (TR) risk reduction in a lithium ion battery for human space flight by developing and implementing verifiable design features which interrupt energy transfer between adjacent electrochemical cells. Conventional lithium ion (li-Ion) batteries can fail catastrophically as a result of a single cell going into thermal runaway. Thermal runaway results when an internal component fails to separate electrode materials leading to localized heating and complete combustion of the lithium ion cell. Previously, the greatest control to minimize the probability of cell failure was individual cell screening. Combining thermal runaway propagation mitigation design features with a comprehensive screening program reduces both the probability, and the severity, of a single cell failure.

Sudden cardiac death and preparticipation screening: the debate continues-in support of electrocardiogram-inclusive preparticipation screening.

PubMed

Asif, Irfan M; Drezner, Jonathan A

2012-01-01

Sudden cardiac death (SCD) is the leading cause of death in young athletes during exercise, and there is international agreement among major medical and sporting bodies that young athletes should undergo preparticipation cardiovascular screening. However, there is currently no universally accepted screening protocol, and substantial debate exists about what constitutes the ideal approach to preparticipation screening. The primary objective of preparticipation screening is the detection of intrinsic structural or electrical cardiovascular disorders that predispose an athlete to SCD. Considerable evidence exists suggesting that screening athletes with only a history and physical examination leaves most athletes with a serious underlying cardiovascular disease undetected and, thus, cannot adequately achieve the primary objective of screening. Preparticipating cardiovascular screening inclusive of an electrocardiogram (ECG) greatly enhances the ability to identify athletes at risk and is the only model shown to be cost-effective and may reduce the rate of SCD. The major obstacle to ECG screening in the United States is the lack of a physician workforce skilled in interpretation of an athlete's ECG. However, recent studies have demonstrated a capacity to distinguish physiologic ECG alterations in athletes from findings suggestive of underlying pathology that is both feasible and has a low false-positive rate. Efforts are underway to increase physician education in ECG interpretation. After 2 decades debating the proper screening strategy to identify athletes at risk, the weight of scientific evidence suggests that a screening program inclusive of ECG is the only strategy that merits promotion.

Oral cancer and precancer appear to fulfil many of the criteria for a disease suitable for mass screening. Several commercial organisations in the UK have introduced screening for their employees. One program has been formally evaluated over the course of 1 yr. Of 553 company headquarters staff aged > or = 40 yr, 292 (53%) responded to the well-publicised screening invitation and received a simple clinical examination of the oral mucosa from one of two company dentists. In addition, 17 staff were screened from a separate company work-site. After screening, subjects were examined independently by an oral medicine specialist with access to the relevant diagnostic aids. The dentists' screening decisions were validated against the specialist's definitive diagnoses (the 'gold standard'). The true prevalence of subjects with lesions diagnosed as positive (white patch, red patch or ulcer of greater than 2 weeks' duration) was 17 (5.5%). Overall, sensitivity was 0.71 and specificity, 0.99. The compliance rate to screening among headquarters subjects in seven occupational categories did not differ significantly from the occupational profile for all headquarters personnel. Estimates of relative risk of a positive diagnosis were calculated by logistic regression for five independent variables; gender, age, moderate smoking, heavy smoking, and smoking combined with greater than low risk alcohol consumption. Only heavy smoking (> or = 20 cigarettes per day) produced a significant odds ratio (3.43, P < 0.05).

Korean American women's perceptions about physical examinations and cancer screening services offered in Korea: the influences of medical tourism on Korean Americans.

Cancer is the leading cause of death for Korean-Americans (KAs), while cancer screening rates among KAs have been consistently low. Seven semi-structured focus group interviews with 34 KA women aged 40 or older in the Washington, DC metropolitan area were conducted to explore the perceptions of KA women about seeking physical examinations and cancer screening services in Korea. Data were analyzed using a framework approach. Informants positively perceived the use of health screening services in Korea in comparison to seeking such services in the US. Decision-making factors included cost benefits, high quality services, and more convenient screening procedures in Korea. These benefits outweighed the risks of delaying health care and travelling a vast distance with incurring additional travel costs. Motivations to seek these services in Korea included opportunities to visit their homeland and to enjoy comfortable communication with their native language. The increase of available information about Korean medical services due to the industry's aggressive marketing/PR was identified as a facilitator. Most informants did not recognize possible negative health outcomes of obtaining services in Korea such as inappropriate follow up care if having abnormal findings. Educational programs are needed to educate KAs about the benefits and risks of getting the services in Korea and proper follow up care in the US. Health care providers need to know the different cancer risks and screening needs for this population.

Lohmann, R. A.; Riecke, G. T.

1977-01-01

An analytical screening study was conducted to identify duct burner concepts capable of providing low emissions and high performance in advanced supersonic engines. Duct burner configurations ranging from current augmenter technology to advanced concepts such as premix-prevaporized burners were defined. Aerothermal and mechanical design studies provided the basis for screening these configurations using the criteria of emissions, performance, engine compatibility, cost, weight and relative risk. Technology levels derived from recently defined experimental low emissions main burners are required to achieve both low emissions and high performance goals. A configuration based on the Vorbix (Vortex burning and mixing) combustor concept was analytically determined to meet the performance goals and is consistent with the fan duct envelope of a variable cycle engine. The duct burner configuration has a moderate risk level compatible with the schedule of anticipated experimental programs.

Cancer in the Transplant Recipient

Malignancy has become one of the three major causes of death after transplantation in the past decade and is thus increasingly important in all organ transplant programs. Death from cardiovascular disease and infection are both decreasing in frequency from a combination of screening, prophylaxis, aggressive risk factor management, and interventional therapies. Cancer, on the other hand, is poorly and expensively screened for; risk factors are mostly elusive and/or hard to impact on except for the use of immunosuppression itself; and finally therapeutic approaches to the transplant recipient with cancer are often nihilistic. This article provides a review of each of the issues as they come to affect transplantation: cancer before wait-listing, cancer transmission from the donor, cancer after transplantation, outcomes of transplant recipients after a diagnosis of cancer, and the role of screening and therapy in reducing the impact of cancer in transplant recipients.

Cost-Effectiveness of Enhanced Syphilis Screening among HIV-Positive Men Who Have Sex with Men: A Microsimulation Model

Tuite, Ashleigh R.; Burchell, Ann N.; Fisman, David N.

2014-01-01

Background Syphilis co-infection risk has increased substantially among HIV-infected men who have sex with men (MSM). Frequent screening for syphilis and treatment of men who test positive might be a practical means of controlling the risk of infection and disease sequelae in this population. Purpose We evaluated the cost-effectiveness of strategies that increased the frequency and population coverage of syphilis screening in HIV-infected MSM receiving HIV care, relative to current standard of care. Methods We developed a state-transition microsimulation model of syphilis natural history and medical care in HIV-infected MSM receiving care for HIV. We performed Monte Carlo simulations using input data derived from a large observational cohort in Ontario, Canada, and from published biomedical literature. Simulations compared usual care (57% of the population screened annually) to different combinations of more frequent (3- or 6-monthly) screening and higher coverage (100% screened). We estimated expected disease-specific outcomes, quality-adjusted survival, costs, and cost-effectiveness associated with each strategy from the perspective of a public health care payer. Results Usual care was more costly and less effective than strategies with more frequent or higher coverage screening. Higher coverage strategies (with screening frequency of 3 or 6 months) were expected to be cost-effective based on usually cited willingness-to-pay thresholds. These findings were robust in the face of probabilistic sensitivity analyses, alternate cost-effectiveness thresholds, and alternate assumptions about duration of risk, program characteristics, and management of underlying HIV. Conclusions We project that higher coverage and more frequent syphilis screening of HIV-infected MSM would be a highly cost-effective health intervention, with many potentially viable screening strategies projected to both save costs and improve health when compared to usual care. The baseline requirement for regular blood testing in this group (i.e., for viral load monitoring) makes intensification of syphilis screening appear readily practicable. PMID:24983455

Innovative approaches to cervical cancer screening for sex trade workers: an international scoping review.

PubMed

Thulien, Naomi S

2014-03-01

Female sex trade workers are among those at highest risk for developing and dying of cervical cancer, and yet many-particularly the most marginalized-are less likely than other women to be screened. This review summarizes global findings on innovative approaches to cervical cancer screening for female sex trade workers, highlights current gaps in the delivery of cervical cancer screening for female sex trade workers globally, and suggests areas for future research and policy development. A scoping review of peer-reviewed publications and grey literature was conducted. Medline (OVID), PubMed, EMBASE, and SCOPUS were searched for relevant studies written in English. There were no limitations placed on dates. Grey literature was identified by hand searching and through discussion with health care providers and community outreach workers currently working with sex trade workers. Twenty-five articles were deemed suitable for review. Articles detailing innovative ways for female sex trade workers to access cervical cancer screening were included. Articles about screening for sexually transmitted infections were also included if the findings could be generalized to screening for cervical cancer. Articles limited to exploring risk factors, knowledge, awareness, education, prevalence, and incidence of cervical cancer among sex trade workers were excluded from the review. Successful screening initiatives identified in the studies reviewed had unconventional hours of operation, understood the difference between street-based and venue-based sex trade workers, and/or used peers for outreach. Two significant gaps in health care service delivery were highlighted in this review: the limited use of unorthodox hours and the nearly exclusive practice of providing sexually transmitted infection screening for female sex trade workers without cervical cancer screening. In addition, although street-based (as opposed to venue-based) sex trade workers are likely at higher risk for developing cervical cancer, they are much less likely than other eligible women to participate in screening programs, meaning traditional outreach methods are unlikely to be successful.

To estimate the cost-effectiveness of targeted and universal screening for vasa praevia at 18-20 weeks of gestation in singleton and twin pregnancies. Cost-utility analysis based on a decision-analytic model comparing relevant strategies and life-long outcomes for mother and infant(s). Ontario, Canada. A cohort of pregnant women in 1 year. We constructed a decision-analytic model to estimate the lifetime incremental costs and benefits of screening for vasa praevia. Inputs were estimated from the literature. Costs were collected from the London Health Sciences Centre, the Ontario Health Insurance Program, and other sources. We used one-way, scenario and probabilistic sensitivity analysis to determine the robustness of the results. Incremental costs, life expectancy, quality-adjusted life-years (QALY) and incremental cost-effectiveness ratio (ICER). Universal transvaginal ultrasound screening of twin pregnancies has an ICER of $5488 per QALY-gained. Screening all singleton pregnancies with the risk factors low-lying placentas, in vitro fertilisation (IVF) conception, accessory placental lobes, or velamentous cord insertion has an ICER of $15,764 per QALY-gained even though identifying some of these risk factors requires routine use of colour Doppler during transabdominal examinations. Screening women with a marginal cord insertion costs an additional $27,603 per QALY-gained. Universal transvaginal screening for vasa praevia in singleton pregnancies costs $579,164 per QALY compared with targeted screening. Compared with current practice, screening all twin pregnancies for vasa praevia with transvaginal ultrasound is cost-effective. Among the alternatives considered, the use of colour Doppler at all transabdominal ultrasound examinations of singleton pregnancies and targeted use of transvaginal ultrasound for IVF pregnancies or when the placenta has been found to be associated with one or more risk factors is cost-effective. Universal screening of singleton pregnancies is not cost-effective compared with targeted screening.

Annual diabetic eye screening has been implemented in England since 2008. This study aimed to estimate changes in the detection of retinopathy in the first 4 years of the program. Participants included 32,340 patients with type 2 diabetes resident in three London boroughs with one or more screening records between 2008 and 2011. Data for 87,570 digital images from 2008 to 2011 were analyzed. Frequency of sight-threatening diabetic retinopathy (STDR) was estimated by year of screen for first screens and for subsequent screens according to retinopathy status at first screen. Among 16,621 first-ever screens, the frequency of STDR was 7.1% in 2008, declining to 6.4% in 2011 (P = 0.087). The proportion with a duration of diabetes of <1 year at first screen increased from 18.7% in 2008 to 48.6% in 2011. Second or later screens were received by 26,308 participants. In participants with mild nonproliferative retinopathy at first screen, the proportion with STDR at second or later screen declined from 21.6% in 2008 to 8.4% in 2011 (annual change -2.2% [95% CI -3.3 to -1.0], P < 0.001). In participants with no retinopathy at first screen, STDR declined from 9.2% in 2008 to 3.2% in 2011 (annual change -1.8% [-2.0 to -1.7], P < 0.001). Declining trends were similar in sociodemographic subgroups. After the inception of population-based diabetic eye screening, patients at lower risk of STDR contribute an increasing proportion to the eligible population, and the proportion detected with STDR at second or subsequent screening rounds declines rapidly.

A Multidisciplinary Sepsis Program Enabled by a Two-Stage Clinical Decision Support System: Factors That Influence Patient Outcomes.

2016-11-01

Sepsis is an inflammatory response triggered by infection, with risk of in-hospital mortality fueled by disease progression. Early recognition and intervention by multidisciplinary sepsis programs may reverse the inflammatory response among at-risk patient populations, potentially improving outcomes. This retrospective study of a sepsis program enabled by a 2-stage sepsis Clinical Decision Support (CDS) system sought to evaluate the program's impact, identify early indicators that may influence outcomes, and uncover opportunities for quality improvement. Data encompassed 16 527 adult hospitalizations from 2014 and 2015. Of 2108 non-intensive care unit patients screened-in by sepsis CDS, 97% patients were stratified by 177 providers. Risk of adverse outcome improved 30% from baseline to year end, with gains materializing and stabilizing at month 7 after sepsis program go-live. Early indicators likely to influence outcomes include patient age, recent hospitalization, electrolyte abnormalities, hypovolemic shock, hypoxemia, patient location when sepsis CDS activated, and specific alert patterns. © The Author(s) 2015.

Background. This work examines the occurrence of interval colorectal cancers (CRCs) in the Ontario ColonCancerCheck (CCC) program. We define interval CRC as CRC diagnosed within 2 years following normal guaiac fecal occult blood testing (gFOBT). Methods. Persons aged 50-74 who completed a baseline CCC gFOBT kit in 2008 and 2009, without a prior history of CRC, or recent colonoscopy, flexible sigmoidoscopy, or gFOBT, were identified. Rates of CRC following positive and normal results at baseline and subsequent gFOBT screens were computed and overall survival was compared between those following positive and normal results. Results. Interval CRC was diagnosed within 24 months following the baseline screen among 0.16% of normals and following the subsequent screen among 0.18% of normals. Interval cancers comprised 38.70% of CRC following the baseline screen and 50.86% following the subsequent screen. Adjusting for age and sex, the hazard ratio (HR) for death following interval cancer compared to CRC following positive result was 1.65 (1.32, 2.05) following the first screen and 1.71 (1.00, 2.91) following the second screen. Conclusion. Interval CRCs following gFOBT screening comprise a significant proportion of CRC diagnosed within 2 years after gFOBT testing and are associated with a higher risk of death.

Social representations of human papillomavirus in Bogotá, Colombia.

2012-01-01

Identifying DNA of Human papillomavirus (HPV) has been proposed as a new screening method for cervical cancer control. Conventionally, health education for screening programs is based on scientific information without considering any community cognitive processes. We examine HPV social representations of 124 men and women from diverse educational status living in Bogotá, Colombia. The social representation of HPV involves a series of figurative nuclei derived from meanings linked to scientific information. While women focused on symbols associated to contagion, men focused on its venereal character. Figurative nuclei also included long-term uncertainty, need or urgent treatment, and feelings of imminent death associated with cancer and chronic sexually transmitted infections. The social representation of HPV impeded many participants from clearly understanding written information about HPV transmission, clearance, and cancer risk; they are built into a framework of values, which must be deconstructed to allow women full participation in HPV screening programs.

Although several quality indicators of colonoscopy have been defined, quality assurance activities should be directed at the measurement of quality indicators that are predictive of key screening colonoscopy outcomes. The goal of this study was to examine the association among established quality indicators and the detection of screen-relevant lesions (SRLs), adverse events, and postcolonoscopy cancers. Historical cohort study. Canadian colorectal cancer screening center. A total of 18,456 asymptomatic men and women ages 40 to 74, at either average risk or increased risk for colorectal cancer because of a family history, who underwent a screening colonoscopy from 2008 to 2010. Using univariate and multivariate analyses, we explored the association among procedural quality indicators and 3 colonoscopy outcomes: detection of SRLs, adverse events, and postcolonoscopy cancers. The crude rates of SRLs, adverse events, and postcolonoscopy cancers were 240, 6.44, and .54 per 1000 colonoscopies, respectively. Several indicators, including endoscopist withdrawal time (OR, 1.3; 95% CI, 1.2-1.4) and cecal intubation rate (OR, 13.9; 95% CI, 1.9-96.9), were associated with the detection of SRLs. No quality indicator was associated with the risk of adverse events. Endoscopist average withdrawal time over 6 minutes (OR, .12; 95% CI, .002-.85) and SRL detection rate over 20% (OR, .17; 95% CI, .03-.74) were associated with a reduced risk of postcolonoscopy cancers. Single-center study. Quality assurance programs should prioritize the measurement of endoscopist average withdrawal time and adenoma (SRL) detection rate.

To assess the cost-effectiveness of screening for latent tuberculosis infection (LTBI) using a commercially available detection test and treating individuals at high risk for human immunodeficiency virus (HIV) infection in a middle-income country. We developed a Markov model to evaluate the cost per LTBI case detected, TB case averted and quality-adjusted life year (QALY) gained for a cohort of 1000 individuals at high risk for HIV infection over 20 years. Baseline model inputs for LTBI prevalence were obtained from published literature and cross-sectional data from tuberculosis (TB) screening using QuantiFERON-TB Gold In-Tube (QFT-GIT) testing among sex workers and illicit drug users at high risk for HIV recruited through street outreach in Tijuana, Mexico. Costs are reported in 2007 US dollars. Future costs and QALYs were discounted at 3% per year. Sensitivity analyses were performed to evaluate model robustness. Over 20 years, we estimate the program would prevent 78 cases of active TB and 55 TB-related deaths. The incremental cost per case of LTBI detected was US$730, cost per active TB averted was US$529 and cost per QALY gained was US$108. In settings of endemic TB and escalating HIV incidence, targeting LTBI screening and treatment among high-risk groups may be highly cost-effective.

Objectives We estimated the percentage of women infected with human papillomavirus (HPV+) who cannot be immediately treated with cryotherapy. Materials and Methods In a 10,000-woman Costa Rican cohort, we analyzed the 559 HPV+ women aged 25-55, and estimated the proportion for whom immediate cryotherapy was not indicated (i.e., invasive cancer, large precancerous lesions, or benign abnormalities that risk failure such as large ectopy, squamocolumnar junction not visualized, polyps, ulcers, or distorted or atrophied cervix). To determine whether cryotherapy at time of baseline HPV screening would effectively treat HPV+ women, two expert gynecologists independently judged entire clinical histories (5-7 years of cytology, histology, and HPV tests) and a full longitudinal series of digitized cervical images.. Results Reviewers judged 144 (25.8%) of 559 HPV+ women as not treatable by immediate cryotherapy. Among 72 women with cervical intraepithelial neoplasia grade 3 (CIN3) who would benefit most from a screening program, 35 (48.6%) were not treatable. In particular, 29 women (40.3%) were determined not treatable for reasons most likely associated with cryotherapy's inadequacy (lesion was large, suspected cancerous or in the endocervical canal or fornix). Conclusions “Screen-and-treat” programs in low-resource settings will soon use a rapid HPV test to screen older women once or twice in their lifetime, identifying women at higher risk for precancer. Our findings suggest cryotherapy might not effectively treat many precancers and other safe, low-technology treatment options could be required, in a scenario where all HPV+ women in this targeted group would receive cryotherapy at the same visit.

Background. Because recently infected individuals disproportionately contribute to the spread of human immunodeficiency virus (HIV), we evaluated the impact of a primary HIV screening program (the Early Test) implemented in San Diego. Methods. The Early Test program used combined nucleic acid and serology testing to screen for primary infection targeting local high-risk individuals. Epidemiologic, HIV sequence, and geographic data were obtained from the San Diego County Department of Public Health and the Early Test program. Poisson regression analysis was performed to determine whether the Early Test program was temporally and geographically associated with changes in incident HIV diagnoses. Transmission chains were inferred by phylogenetic analysis of sequence data. Results. Over time, a decrease in incident HIV diagnoses was observed proportional to the number primary HIV infections diagnosed in each San Diego region (P < .001). Molecular network analyses also showed that transmission chains were more likely to terminate in regions where the program was marketed (P = .002). Although, individuals in these zip codes had infection diagnosed earlier (P = .08), they were not treated earlier (P = .83). Conclusions. These findings suggests that early HIV diagnoses by this primary infection screening program probably contributed to the observed decrease in new HIV diagnoses in San Diego, and they support the expansion and evaluation of similar programs.

Coronary heart disease (CHD) is the number one cause of death in the U.S. It is a likely cause of death and disability in the lives of employees at Kennedy Space Center (KSC) as well. The KSC Biomedical Office used a multifactorial formula developed by the Framingham Heart Study to calculate CHD risk probabilities for individuals in a segment of the KSC population who require medical evaluation for job certification. Those individuals assessed to have a high risk probability will be targeted for intervention.

In the United States, the cardiovascular health of women is affected by the disparate impact of cardiovascular diseases (CVDs) on many minority ethnic and racial groups. Women with low income also endure a disproportionate impact of the burden of CVD. The Centers for Disease Control and Prevention's (CDC's) Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) Program was authorized by Congress in 1993 to extend the preventive health services offered to participants of the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). These are low-income, uninsured, and underinsured women. The intent was to expand services of an existing federal program to address cardiovascular health concerns in this vulnerable, high-risk population. CDC funds 19 state health departments and 2 tribal organizations (both in Alaska) to implement WISEWOMAN. In the first 2 years of the current 5-year funding cycle, which began in June 2008, the WISEWOMAN grantees succeeded in providing almost 78,000 screenings, of which 46% were to women of minority racial and ethnic groups. The individual successes are important, and the WISEWOMAN Program also has achieved success in the broader arenas of healthcare and the communities in which WISEWOMAN is implemented. WISEWOMAN impacts clinical systems of care, provider education, physician extenders, and the broader community and will continue to play an important role in connecting low-income, uninsured, and underinsured women with clinical systems of care and other community resources that will result in the prevention, treatment, and management of their CVD risk.

This study examined the prevalence of metabolic syndrome and the risk level of cardiovascular disease (CVD) in a vulnerable population of 407 subjects in Korea. This descriptive study was a part of the Tailed Health Visiting Service Program, using baseline data from public health centres in Suwon, Korea. The definition of metabolic syndrome was based on the National Cholesterol Education Program criteria, and risk of CVD was estimated according to the Framingham study equation. This study demonstrated that the prevalence of metabolic syndrome was 40.8% higher and the risk of CVD was significantly 3.1 times higher among those with metabolic syndrome than among those without it. Of those with metabolic syndrome, 50.6% overall and 81.1% of men had a high risk for CVD. These findings suggest a need to screen and prevent the risk of CVD in vulnerable populations with metabolic syndrome. © 2014 Wiley Publishing Asia Pty Ltd.

Effect of Neurocognition and Concussion on Musculoskeletal Injury Risk

Herman, Daniel C.; Zaremski, Jason L.; Vincent, Heather K.; Vincent, Kevin R.

2015-01-01

Research regarding musculoskeletal injury risk has focused primarily on anatomical, neuromuscular, hormonal, and environmental risk factors; however, subsequent injury risk screening and intervention programs have been largely limited to neuromuscular factors and have faced challenges in both implementation and efficacy. Recent studies indicate that poor neurocognitive performance, either at baseline or in the aftermath of a concussion, is associated with elevated risk of musculoskeletal injury. Despite the relatively limited current understanding regarding the nature of the relationship between different aspects of neurocognitive performance and musculoskeletal injury risk, this is a promising area of research that may yield significant advances in musculoskeletal injury risk stratification, rehabilitation, and prevention.

The scientific and public debate concerning organized mammography screening is unprecedentedly strong. With research evidence concerning its efficacy being ambiguous, the recommendations pertaining to the age-thresholds for program inclusion vary between - and even within - countries. Data shows that young women who are not yet eligible for systematic screening, have opportunistic mammograms relatively often and, moreover, want to be included in organized programs. Yet, to date, little is known about the precise motivations underlying young women's desire and intentions to go for, not medically indicated, mammographic screening. A cross-sectional online survey was carried out among women aged 30-49 years (n = 918) from Switzerland. The findings show that high fear (β = .08, p ≤ .05), perceived susceptibility (β = .10, p ≤ .05), and ego-involvement (β = .34, p ≤ .001) are the main predictors of screening intentions among women who are not yet eligible for the systematic program. Also, geographical location (Swiss-French group: β = .15, p ≤ .001; Swiss-Italian group: β = .26, p ≤ .001) and age (β = .11, p ≤ .001) play a role. In turn, breast cancer knowledge, risk perceptions, and educational status do not have a significant impact. Young women seem to differ inherently from those who are already eligible for systematic screening in terms of the factors underlying their intentions to engage in mammographic screening. Thus, when striving to promote adherence to systematic screening guidelines - whether based on unequivocal scientific evidence or policy decisions - and to allow women to make evidence-based, informed decisions about mammography, differential strategies are needed to reach different age-groups.

β-thalassemia is an autosomal recessive blood disorder caused by gene mutations that affect all aspects of β-globin production. In majority of Asian countries including India, the frequency of β-thalassemia is closely intertwined with social, cultural, and religious issues of the respective country. Several national level screening programs imparted education regarding β-thalassemia, but follow-up evaluation revealed that education was not effective. It has been hypothesized that the beliefs and attitudes, carrier screening, and education among "high risk communities" will have far-reaching implications towards β-thalassemia prevention in the country. The present study is aimed to investigate attitudes, intention, and behavior of β-thalassemia high- and low-risk ethnic groups towards carrier screening and education. A structured questionnaire on knowledge, attitude, and practice regarding β-thalassemia was administered on 926 individuals belong to Arora, a high-risk ethnic group for β-thalassemia (347 rural (AR) and 202 urban (AU)) and 377 cosmopolitan commoners (CC) aged above 18 years of both sexes. To understand the relationship between various questions, Pearson's correlation test and factor analysis was performed. The responses were further categorized into the theory of planned behavior (TPB) constructs with the measures of the main constructs reported as a mean. Various dimensions of knowledge, attitude, and practice reveal that the urban groups (AU and CC) are better aware of the disease "β-thalassemia" than the rural group (AR) who witness suffering at close quarters. The AR group is more positive for preventive measures than the urban groups. Significant correlations and factor analysis show "intentions" for premarital and prenatal screening highly loaded as outcome behaviors. The Ajzen's "Theory of planned behavior" support that the "intention" and "perceived behavior control" are better predictors of "outcome behavior" compared to "attitude" and "subjective norm." As this study is cross-sectional and descriptive in nature, the constructs of the theory should be considered as perceptions. However, we believe the patterns observed are indicative of "predicting behavior" that has far-reaching implications on health planners and administrators in designing β-thalassemia screening and prevention program.

NASA Human System Risk Assessment Process

NASA utilizes an evidence based system to perform risk assessments for the human system for spaceflight missions. The center of this process is the multi-disciplinary Human System Risk Board (HSRB). The HSRB is chartered from the Chief Health and Medical Officer (OCHMO) at NASA Headquarters. The HSRB reviews all human system risks via an established comprehensive risk and configuration management plan based on a project management approach. The HSRB facilitates the integration of human research (terrestrial and spaceflight), medical operations, occupational surveillance, systems engineering and many other disciplines in a comprehensive review of human system risks. The HSRB considers all factors that influence human risk. These factors include pre-mission considerations such as screening criteria, training, age, sex, and physiological condition. In mission factors such as available countermeasures, mission duration and location and post mission factors such as time to return to baseline (reconditioning), post mission health screening, and available treatments. All of the factors influence the total risk assessment for each human risk. The HSRB performed a comprehensive review of all potential inflight medical conditions and events and over the course of several reviews consolidated the number of human system risks to 30, where the greatest emphasis is placed for investing program dollars for risk mitigation. The HSRB considers all available evidence from human research and, medical operations and occupational surveillance in assessing the risks for appropriate mitigation and future work. All applicable DRMs (low earth orbit for 6 and 12 months, deep space for 30 days and 1 year, a lunar mission for 1 year, and a planetary mission for 3 years) are considered as human system risks are modified by the hazards associated with space flight such as microgravity, exposure to radiation, distance from the earth, isolation and a closed environment. Each risk has a summary two-page assessment representing the state of knowledge/evidence of that risk, available risk mitigations, traceability to the Space Flight Human System Standards (SFHSS) and program requirements, and future work required. These data then can drive coordinated budgets across the Human Research Program, the International Space Station, Crew Health and Safety and Advanced Exploration System budgets to provide the most economical and timely mitigations. The risk assessments were completed for the 6 DRMs and serve as the baseline for which subsequent research and technology development and crew health care portfolios can be assessed. The HSRB reviews each risk at least annually or when new evidence/information is available that adds to the body of evidence. The current status of each risk can be reported to program management for operations, budget reviews and general oversight of the human system risk management program.

[Social impact of screening and of medical surveillance on people exposed to asbestos].

A medical screening program has collective and individual impact. The collective benefit of medical screening for people exposed to asbestos would be financial (better compensation of occupational diseases related to asbestos). The cost of compensation would be attributed to the special assurance fund for occupational diseases. A medical screening of asbestos diseases would set an example for other Public health problems. It would be important for admission of social damage for the French nation. For individuals, social benefits would be better (compensation during work stop and annuities). But screening can have a negative psychological impact for asymptomatic persons. Persons exposed to asbestos and patients with asbestos diseases are able to quit their job for anticipated retirement. Is it a benefit for patients with mesothelioma or lung cancer? It is a very important benefit for asbestosis. The risk is to change the objective of medical screening into a social screening. The financial and medical benefits of screening for hyaline plaques is very poor. Awarding social damage is important for individuals.

Background Cryptococcal meningitis is a leading cause of death in AIDS patients and contributes substantially to the high early mortality in antiretroviral treatment (ART) programs in low-resource settings. Screening for cryptococcal antigen (CRAG) in patients enrolling in ART programs may identify those at risk of cryptococcal meningitis and permit targeted use of pre-emptive therapy. Methods In this retrospective study, CRAG was measured in stored plasma samples obtained from patients as they enrolled in a well characterised ART cohort in South Africa. The predictive value of screening for CRAG prior to ART for development of microbiologically confirmed cryptococcal meningitis or death during the first year of follow-up was determined. Results Of 707 participants with a baseline median CD4 count of 97 (IQR 46-157) cells/μL, 46 (7%) had a positive CRAG. Antigenaemia was 100% sensitive for predicting development of cryptococcal meningitis during the first year of ART and in multivariate analysis was an independent predictor of mortality (AHR 3.2, 95%CI 1.5-6.6). Most (92%) cases of cryptococcal meningitis developed in patients with a CD4 count ≤100 cells/μL. In this sub-set of patients, a CRAG titre ≥1 in 8 was 100% sensitive and 96% specific for predicting incident cryptococcal meningitis during the first year of ART in those with no previous history of the disease. Conclusions CRAG screening prior to commencing ART in patients with a CD4 count ≤100 cells/μL is highly effective at identifying those at risk of cryptococcal meningitis and death and might permit implementation of a targeted pre-emptive treatment strategy.

Kidney transplant recipients are at higher risk of cancer at most sites, and cancer after transplantation causes considerable morbidity and mortality. To optimize long-term patient outcomes, clinicians balance the prospect of graft failure and dialysis, with competing risks of diabetes, cardiovascular and cerebrovascular disease and the risk of malignancy. In this paper we critically examine the assumptions underpinning primary prevention, immunization, chemoprevention and screening programs, and highlight considerations when applying evidence to the kidney transplant population, and suggest a clinical research agenda that aims to define a rational approach to managing posttransplant cancer risk.

Carrier screening for hemoglobinopathies (HbPs; sickle cell disease and thalassemia) aims to facilitate autonomous reproductive decision-making. In the absence of a Dutch national HbP carrier screening program, some primary care midwives offer screening on an ad hoc basis. This qualitative descriptive study explores how pregnant women perceive an offer of HbP carrier screening by their midwife. Semi-structured interviews (n = 26) were conducted with pregnant women at risk of being a HbP carrier, and whom were offered screening at their booking appointment in one of two midwifery practices in Amsterdam. The results showed that half of the respondents were familiar with HbPs. Generally, women perceived the offer of HbP carrier screening as positive, and most women (n = 19) accepted screening. Seven declined, of whom two already knew their carrier status. Important reasons to accept screening were to obtain knowledge about their own carrier status and health of their unborn child, and the ease of the procedure. A multistep process of decision-making was observed, as many women did not give follow-up testing (e.g. partner, invasive diagnostics) much consideration while deciding on accepting or declining HbP screening. Women experienced information overload, and preferred receiving the information at a different moment (e.g. before the intake by a leaflet, or preconceptionally). In conclusion, while prenatal HbP carrier screening is perceived as positive, informed decision-making seems to be suboptimal, and both the content and timing of the information provided needs improvement.

Screening for Food Insecurity in Pediatric Clinical Settings: Opportunities and Barriers.

Food insecurity is a serious health concern among children in the United States with 15.3 million children living in food insecure households. The American Academy of Pediatrics recommends that pediatricians screen for food insecurity at health maintenance visits as identifying children at risk is a crucial step in the amelioration of food insecurity. Two surveys were administered in a Midwest pediatric clinic. A cross-sectional survey was electronically distributed to pediatric providers to assess perceptions of food insecurity among patients, provider readiness to conduct food security screenings, and barriers to conducting those screenings. A cross-sectional caregiver survey was administered to assess demographics, household food security status, participation in nutrition assistance programs, and barriers to getting enough food to eat. Descriptive statistics and odds ratios were calculated. Eighty-eight percent of physicians believe that food insecurity is a challenge for some of their patients. Only 15 % of providers reported screening for food insecurity, while 80 % were willing to screen. Physicians were most concerned with knowing how to handle a positive screen. Among caregivers, 57 % screened positive for food insecurity. Those experiencing food insecurity were more likely to be non-white, participate in SNAP and to feel discomfort towards the idea of talking to a doctor or nurse about food needs. Caregivers reporting food insecurity were significantly less likely to have a personal vehicle. Effective food insecurity screening requires addressing caregiver and health provider barriers in order to increase the likelihood of identifying households most at risk.

Towards improving cervical cancer screening in Nigeria: a review of the basics of cervical neoplasm and cytology.

Cervical cancer screening is the key to reducing the incidence and mortality of cervical cancer in developing countries. In the absence of a national screening program, healthcare givers in Nigeria are encouraged to routinely inform and screen eligible women. This review aims at equipping health workers for this task by re-educating them on the basics of the disease and its screening by cytology. Relevant texts and online databases including Pubmed, African Journal Online, and Google Scholar, were searched for relevant literature on the subject area. Persistent infection by a high-risk human papilloma virus, especially types 16 and 18, is necessary for the development of cervical cancer. The exfoliation of cells from the metaplastic squamous cells of transformation zone of the cervix is the basis of cervical cytology. Organized Pap screening reduces the incidence and mortality of cervical cancer, but screening protocols vary. Nevertheless, annual screening is not recommended except for high-risk women such as HIV-positive women. Abnormal Pap smear results are currently reported using either the Bethesda System or the British Society for Clinical Cytology classification, and colposcopy with or without biopsy are necessary when indicated. In conclusion, the use of cervical cytology to detect pre-cancerous lesions followed by an appropriate treatment when necessary is the key to reducing invasive cervical cancer. The task of provider-initiated counseling and testing for cervical cancer by health practitioners requires update on the current etio-pathology of cervical cancer, and its screening as reviewed.

Human papillomavirus DNA testing as an adjunct to cytology in cervical screening programs.

2003-08-01

Our objective was to review current large studies of human papillomavirus (HPV) DNA testing as an adjunct to the Papanicolaou test for cervical cancer screening programs. We analyzed 10 large screening studies that used the Hybrid Capture 2 test and 3 studies that used the polymerase chain reaction test in a manner that enabled reliable estimates of accuracy for detecting or predicting high-grade cervical intraepithelial neoplasia (CIN). Most studies allowed comparison of HPV DNA and Papanicolaou testing and estimates of the performance of Papanicolaou and HPV DNA as combined tests. The studies were selected on the basis of a sufficient number of cases of high-grade CIN and cancer to provide meaningful statistical values. Investigators had to demonstrate the ability to generate reasonably reliable Hybrid Capture 2 or polymerase chain reaction data that were either minimally biased by nature of study design or that permitted analytical techniques for addressing issues of study bias to be applied. Studies had to provide data for the calculation of test sensitivity, specificity, predictive values, odds ratios, relative risks, confidence intervals, and other relevant measures. Final data were abstracted directly from published articles or estimated from descriptive statistics presented in the articles. In some studies, new analyses were performed from raw data supplied by the principal investigators. We concluded that HPV DNA testing was a more sensitive indicator for prevalent high-grade CIN than either conventional or liquid cytology. A combination of HPV DNA and Papanicolaou testing had almost 100% sensitivity and negative predictive value. The specificity of the combined tests was slightly lower than the specificity of the Papanicolaou test alone, but this decrease could potentially be offset by greater protection from neoplastic progression and cost savings available from extended screening intervals. One "double-negative" HPV DNA and Papanicolaou test indicated better prognostic assurance against risk of future CIN 3 than 3 subsequent negative conventional Papanicolaou tests and may safely allow 3-year screening intervals for such low-risk women.

We evaluated the significance of focal prostate cancer found in sextant biopsies in men participating in a biennial prostate specific antigen (PSA) based screening program. In 1995, 10000 men 50 to 65 years old were randomized to biennial screening with PSA testing. Sextant biopsies were recommended when total PSA was 3 ng/ml or greater at screening rounds 1 and 2, and 2.54 ng/ml or greater at subsequent screening rounds. Focal cancer was defined as total a core cancer length of less than 3 mm in the biopsy specimen. Low volume cancer was defined as a total tumor volume of less than 0.5 cm in the radical retropubic prostatectomy specimen. The number of men who underwent biopsy and the number of cancers detected in the 5 possible sets of biopsies were 1725 and 402, 706 and 124, 307 and 36, 103 and 9, and 13 and 0, respectively. The risk of detecting focal cancer was 7.9%, 10.2%, 7.5%, 5.8% and 0%, respectively, but the relative ratio (focal-to-all cancers) increased 34%, 58%, 64%, 67% and, not applicable, respectively. In men with a total core cancer length of less than 10 mm there was no correlation between core cancer length and total tumor volume, as measured in the prostatectomy specimen. Two-thirds of men with a total core cancer length of less than 3 mm had a tumor volume of greater than 0.5 cm, while the risk of low volume cancer was less than 5% only in men with a total core cancer length of greater than 10 mm. In a repeat PSA based screening program sextant biopsies are of little or no value for predicting tumor volume.

Abdominal aortic aneurysm screening program in Poland.

PubMed

Jawien, A; Formankiewicz, B; Derezinski, T; Migdalski, A; Brazis, P; Woda, L

Screening for abdominal aortic aneurysms (AAA) is currently recommended by several vascular societies. In countries where it has been introduced the prevalence of AAAs differed greatly and was mainly related to cigarette smoking. The screening program also had an enormous impact on the decrease of AAA ruptures and reduced mortality rate. These facts have led to the introduction of the first screening program for AAAs in Poland. The aim of the study was to determine the prevalence of AAAs among men aged 60 years and older undergoing ultrasound examination of the abdominal aorta. A single ultrasonography of the abdomen was performed to assess the aorta from the renal arteries to the bifurcation and the diameter of the aorta was measured at its widest point. The cut-off value for determining an aortic aneurysm was set at a diameter of ≥ 30 mm. All ultrasonography measurements were performed by physicians in outpatient departments throughout the Kuyavian-Pomeranian Province. Additionally, each subject had to fill out a questionnaire with demographic data, smoking habits, existing comorbidities and familial occurrence of AAAs. The study was conducted from October 2009 to November 2011. The abdominal aorta ultrasound examinations were carried out in 1556 men aged 60 years and older. The prevalence of AAA in the study population was 6.0 % (94 out of 1556). The average age of the men was 69 years (SD 6 years, range 60-92 years). In the study population 55 % of the men smoked or had smoked and 3 % were aware of the presence of AAAs in family members. There were three risk factors significantly associated with the presence of AAAs: age (p < 0.05), smoking (72.3 % vs 53.9 %, p = 0.004) and family history of AAAs (9.6 % vs 2.7 %, p = 0.017). The prevalence of AAAs among men in Poland is higher than in other European countries and the USA. The screening program for AAAs is an easy and reliable method for detecting early stages of the disease and risk factors which are the driving forces for the development of AAAs.

A project in a Texas border community setting, Prevention Organized against Diabetes and Dialysis with Education and Resources (POD 2 ER), offered diabetes prevention information, screening, and medical referrals. The setting was a large, longstanding flea market that functions as a shopping mall for low-income people. The priority population included medically underserved urban and rural Mexican Americans. Components of the program addressed those with diabetes, prediabetes, and accompanying relatives and friends. People living in the Lower Rio Grande Valley (LRGV) face challenges of high rates of type 2 diabetes, lack of knowledge about prevention, and inadequate access to medical care. Recent statistics from actual community-wide screenings indicate a high diabetes prevalence, 30.7% among adults in the LRGV compared with 12.3% nationwide. A diverse team composed of public health faculty, students, a physician, a community health worker, and community volunteers conceived and developed the project with a focus on cultural and economic congruence and a user-friendly atmosphere. The program provided screening for prediabetes and diabetes with a hemoglobin A1c test. Screening was offered to those who were at least 25 years of age and not pregnant. When results indicated diabetes, a test for kidney damage was offered (urinary albumin-to-creatinine ratio). A medical appointment at a community clinic within a week was provided to those who tested positive for diabetes and lacked a medical home. Health education modules addressed all family members. The project was successful in recruiting 2,332 high-risk people in 26 months in a community setting, providing clinic referrals to those without a doctor, introducing them to treatment, and providing diabetes prevention information to all project participants. Implications for research and practice are highlighted. This study shows that a regular access point in a place frequented by large numbers of medically marginalized people in a program designed to eliminate cultural and economic barriers can succeed in providing a hard-to-reach community with diabetes prevention services. Aspects of this program can serve as a model for other service provision for similar populations and settings.
