After careful pilot studies and planning, the national screening program for colorectal cancer (CRC), with biennial fecal immunochemical tests (FITs), was initiated in The Netherlands in 2014. A national information system for real-time monitoring was developed to allow for timely evaluation. Data were collected from the first year of this screening program to determine the importance of planning and monitoring for optimal screening program performance. The national information system of the CRC screening program kept track of the number of invitations sent in 2014, FIT kits returned, and colonoscopies performed. Age-adjusted rates of participation, the number of positive test results, and positive predictive values (PPVs) for advanced neoplasia were determined weekly, quarterly, and yearly. In 2014, there were 741,914 persons invited for FIT; of these, 529,056 (71.3%; 95% CI, 71.2%-71.4%) participated. A few months into the program, real-time monitoring showed that rates of participation and positive test results (10.6%; 95% CI, 10.5%-10.8%) were higher than predicted and the PPV was lower (42.1%; 95% CI, 41.3%-42.9%) than predicted based on pilot studies. To reduce the burden of unnecessary colonoscopies and alleviate colonoscopy capacity, the cut-off level for a positive FIT result was increased from 15 to 47 μg Hb/g feces halfway through 2014. This adjustment decreased the percentage of positive test results to 6.7% (95% CI, 6.6%-6.8%) and increased the PPV to 49.1% (95% CI, 48.3%-49.9%). In total, the first year of the Dutch screening program resulted in the detection of 2483 cancers and 12,030 advanced adenomas. Close monitoring of the implementation of the Dutch national CRC screening program allowed for instant adjustment of the FIT cut-off levels to optimize program performance.

This article summarizes results from an evaluation of a federally sponsored criminal history screening (CHS) pilot program to improve screening for workers in long-term care settings. The evaluation addressed eight key issues specified through enabling legislation, including efficiency, costs, and outcomes of screening procedures. Of the 204,339 completed screenings, 3.7% were disqualified due to criminal history, and 18.8% were withdrawn prior to completion for reasons that may include relevant criminal history. Lessons learned from the pilot program experiences may inform a new national background check demonstration program.

How to Improve the Quality of Screening Endoscopy in Korea: National Endoscopy Quality Improvement Program.

PubMed

Cho, Yu Kyung

2016-07-01

In Korea, gastric cancer screening, either esophagogastroduodenoscopy or upper gastrointestinal series (UGIS), is performed biennially for adults aged 40 years or older. Screening endoscopy has been shown to be associated with localized cancer detection and better than UGIS. However, the diagnostic sensitivity of detecting cancer is not satisfactory. The National Endoscopy Quality Improvement (QI) program was initiated in 2009 to enhance the quality of medical institutions and improve the effectiveness of the National Cancer Screening Program (NCSP). The Korean Society of Gastrointestinal Endoscopy developed quality standards through a broad systematic review of other endoscopic quality guidelines and discussions with experts. The standards comprise five domains: qualifications of endoscopists, endoscopic unit facilities and equipment, endoscopic procedure, endoscopy outcomes, and endoscopic reprocessing. After 5 years of the QI program, feedback surveys showed that the perception of QI and endoscopic practice improved substantially in all domains of quality, but the quality standards need to be revised. How to avoid missing cancer in endoscopic procedures in daily practice was reviewed, which can be applied to the mass screening endoscopy. To improve the quality and effectiveness of NCSP, key performance indicators, acceptable quality standards, regular audit, and appropriate reimbursement are necessary.

A comparative examination of tuberculosis immigration medical screening programs from selected countries with high immigration and low tuberculosis incidence rates

PubMed Central

2011-01-01

Background Tuberculosis (TB) in migrants is an ongoing challenge in several low TB incidence countries since a large proportion of TB in these countries occurs in migrants from high incidence countries. To meet these challenges, several countries utilize TB screening programs. The programs attempt to identify and treat those with active and/or infectious stages of the disease. In addition, screening is used to identify and manage those with latent or inactive disease after arrival. Between nations, considerable variation exists in the methods used in migration-associated TB screening. The present study aimed to compare the TB immigration medical examination requirements in selected countries of high immigration and low TB incidence rates. Methods Descriptive study of immigration TB screening programs Results 16 out of 18 eligible countries responded to the written standardized survey and phone interview. Comparisons in specific areas of TB immigration screening programs included authorities responsible for TB screening, the primary objectives of the TB screening program, the yield of detection of active TB disease, screening details and aspects of follow up for inactive pulmonary TB. No two countries had the same approach to TB screening among migrants. Important differences, common practices, common problems, evidence or lack of evidence for program specifics were noted. Conclusions In spite of common goals, there is great diversity in the processes and practices designed to mitigate the impact of migration-associated TB among nations that screen migrants for the disease. The long-term goal in decreasing migration-related introduction of TB from high to low incidence countries remains diminishing the prevalence of the disease in those high incidence locations. In the meantime, existing or planned migration screening programs for TB can be made more efficient and evidenced based. Cooperation among countries doing research in the areas outlined in this study should facilitate the development of improved screening programs. PMID:21205318

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

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.

The rates of participation in the Korean nationwide cervical cancer screening program and the rates of abnormal test results were determined. The database of the National Health Insurance Service (NHIS) was used during the study period (2009-2014). The participation rate increased from 41.10% in 2009 to 51.52% in 2014 (annual percentage change, 4.126%; 95% confidence interval [CI]=2.253-6.034). During the study period, women ≥70 years of age had the lowest rate of participation (range, 21.7%-31.9%) and those 30-39 years of age the second-lowest (27.7%-44.9%). The participation rates of National Health Insurance beneficiaries (range, 48.6%-52.5%) were higher than those of Medical Aid Program (MAP) recipients (29.6%-33.2%). The rates of abnormal results were 0.65% in 2009 and 0.52% in 2014, with a decreasing tendency in all age groups except the youngest (30-39 years). Every year the abnormal result rates tended to decrease with age, from the age groups of 30-39 years to 60-69 years but increased in women ≥70 years of age. The ratio of patients with atypical squamous cells of undetermined significance compared with those with squamous intraepithelial lesions increased from 2.71 in 2009 to 4.91 in 2014. Differences related to age and occurring over time were found in the rates of participation and abnormal results. Further efforts are needed to encourage participation in cervical cancer screening, especially for MAP recipients, elderly women and women 30-39 years of age. Quality control measures for cervical cancer screening programs should be enforced consistently. Copyright © 2017. Asian Society of Gynecologic Oncology, Korean Society of Gynecologic Oncology

Has the National Cancer Screening Program reduced income inequalities in screening attendance in South Korea?

2015-11-01

In 1999, the Korean government introduced the National Cancer Screening Program (NCSP) to increase the cancer-screening rate, particularly among the low-income population. This study investigates how the NCSP has decreased both relative and absolute income inequalities in the uptake of cancer screening in South Korea. A nationally representative cross-sectional repeated data from the Korea National Health and Nutrition Examination Survey 1998-2012, managed by the Ministry of Health and Welfare, was used to assess changes over time and the extent of discontinuity at the NCSP-recommended initiation age in the uptake of screening for breast, colorectal, and gastric cancers across income quartiles. Relative inequalities in the uptake of screening for all cancers decreased significantly over the policy period. Absolute inequalities did not change for most cancers, but marginally increased from 9 to 14% points in the uptake of screening for colorectal cancer among men. At the recommended initiation age, absolute inequalities did not change for breast and colorectal cancers but increased from 5 to 16% points for gastric cancer, for which relative inequality significantly decreased. The NCSP, which reduced out-of-pocket payment, may not decrease absolute gap although it leads to overall increases in the uptake of cancer screening and decreases in relative inequalities. Further investigations are needed to understand barriers that prevent the low-income population from attending cancer screening.

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.

National colonoscopy adherence rates near 65% and New York City (NYC) colonoscopy rates approach 69%. Despite an overall increase in national colorectal cancer (CRC) screening rates, rates of CRC screening among Blacks and Latinos are lower than non-Latino Whites. We developed two group level, culturally targeted educational programs about CRC for Blacks and Latinos. One hour programs included education about screening, peer testimony given by a colonoscopy-adherent person, and pre- and post-knowledge assessment. From 2010 to 2012, we conducted 66 education programs in NYC, reaching 1,065 participants, 62.7% of whom were 50 years of age or older identified as Black or Latino and provided information about colonoscopy history (N = 668). Colonoscopy adherence in the sample was 69.3%. There was a significant increase in mean knowledge score about CRC and CRC screening from pretest to posttest. Sixty-eight percent of attendees without prior colonoscopy reported intent to schedule a colonoscopy as a result of attending the program. Culturally targeted education programs with peer testimony are a valuable way to raise awareness about CRC and colonoscopy and can influence intent to screen among nonadherent persons. Additional research is needed to establish group level education as an effective means of promoting CRC screening.

A pan-Canadian web-based education program to support screening for distress: evaluation of outcomes.

McLeod, Deborah L; Morck, Angela C; Curran, Janet A

2014-02-01

Cancer-related distress has been endorsed as the sixth vital sign by many international cancer organizations, and some countries such as Canada have implemented national screening for distress programs. The completion of a screening tool is an important first step in improving responsiveness to cancer-related distress, but screening must be followed with skilled supportive care to make a difference in patient-reported outcomes. Our objective was to create a web-based education program to support nurses and other frontline staff in providing an initial response to screening results. To address screening and supportive care learning needs, the Canadian Association of Psychosocial Oncology (CAPO), with support from the Canadian Partnership Against Cancer, created a web-based education program as one component of the national screening for distress agenda. The program provides clinically grounded and interactive learning through the use of PowerPoint presentations, video clips of clinical interactions with patients and family members, and test questions. Presentation topics include, for example, strategies for dealing with screening results, managing referrals, and supportive counseling. We employed a matched pairs, pre-post survey design to assess the effect of the education program on confidence in screening and in providing initial supportive care. Our analysis of the first 147 matched pairs to complete the course suggests that satisfaction with the course was high. Statistically significant increases in confidence in relation to screening for distress and assessing distress, and in providing initial supportive care, were evident. Our ongoing experience with CAPO's Interprofessional Psychosocial Oncology Distance Education (IPODE) project (www.ipode.ca) project suggests that healthcare professionals value web-based learning for its accessibility and convenience. Such programs appear to offer excellent opportunities for cost-effective education that supports practice change.

Breast screening programs are increasingly controversial, especially regarding two points: the number of breast cancer deaths they avoid, and the problem of over-diagnosis and over-treatment. The French national breast cancer screening program was extended to cover the whole country in 2004. Ten years later it is time to examine the risk/benefit ratio of this program and to discuss the need for change. Like all forms of cancer management, screening must be regularly updated, taking into account the state of the art, new evidence, and uncertainties. All screening providers should keep themselves informed of the latest findings. In the French program, women aged 50-74 with no major individual or familial risk factors for breast cancer are offered screening mammography and clinical breast examination every two years. Images considered non suspicious of malignancy by a first reader are re-examined by a second reader. The devices and procedures are subjected to quality controls. Participating radiologists (both public and private) are required to read at least 500 mammographies per year. The program's national participation rate was 52.7 % in 2012. When individual screening outside of the national program is taken into account (nearly 15 % of women), coverage appears close to the European recommendation of 65 %. Breast cancer mortality has been falling in France by 0.6 % per year for over 30 years, starting before mass screening was implemented, and by 1.5 % since 2005. This decline can be attributed in part to earlier diagnosis and better treatment, so that the specific impact of screening cannot easily be measured. Over-treatment, defined as the detection and treatment of low-malignancy tumors that would otherwise not have been detected in a person's lifetime, is a major negative effect of screening, but its frequency is not precisely known (reported to range from 1 % to 30 %). In view of these uncertainties, it would be advisable to modify the program in order to increase its efficiency, by targeting populations at a higher risk than the women currently included, and to reduce the number of mammograms done outside the program, as they are not subject to the same quality controls. Risks could be reduced by increasing the sensitivity of mammography and the specificity of the readings. Moreover, it is mandatory to inform women of both the benefits and risks of screening, in compliance with the principle of enabling patients to make a free and informed choice.

Background: This study assesses self-reported tobacco use prevalence (cigarette, water-pipe, and medwakh) among applicants to Abu Dhabi's Premarital Screening program during 2011. Methods: Premarital Screening data reported to the Health Authority – Abu Dhabi from April to December 2011 were utilized to estimate tobacco use prevalence among applicants. Smoking prevalence was examined by nationality, age group and gender. Results: Overall, 24.7% of Premarital Screening Program applicants were current smokers; 11.5% smoked cigarettes, 5.9% smoked medwakh (hand-held pipe), 4.8% smoked water-pipe and 2.5% smoked a combination (more than one type). Men (19.2%) were more likely than women (3.5%) to be current cigarette smokers. Women were much less likely to smoke medwakh (0.1%) than men (11.5%), with male UAE Nationals having the highest medwakh smoking prevalence (16.1%). The overall prevalence of water-pipe smoking was 6.8% among men and 2.8% for women with the highest water-pipe smoking prevalence (10.2%) among Arab expatriate men. Conclusions: Variations in tobacco use prevalence among Premarital Screening Program applicants reflect preferences for different modes of tobacco consumption by nationality, age group and gender. Enforcement of tobacco control laws, including implementation of clean indoor air laws and tobacco tax increases, and targeted health education programs are required to reduce tobacco consumption and concomitant tobacco-related morbidity and mortality.

In addition, the provinces' program guidelines, statistical reports, laws, and program regulations were reviewed and certain key leaders were personally interviewed. data were obtained for 19 of Argentina's 24 provinces. Four of the 19 provinces had no formal program framework. Conventional cytology was the most commonly used screening test. Screening was mainly opportunistic. The recommended interval between normal tests was 3 years in most provinces. The eligible age for screening ranged from 10-70 years of age; however, annual or biannual screening was the usual practice after becoming sexually active. None of the provincial programs had data available regarding Pap-smear coverage. Most of the cytology laboratories did not have a quality control policy. The number of smears read varied greatly by laboratory (650-24 000 per year). A log of events related to screening and treatment did not exist in most provinces. screening in Argentina is mainly opportunistic, characterized by an estimated low coverage, coexisting with over-screening of women with access to health services, and an absence of quality control procedures. Policies for cervical cancer screening in the provinces vary and, most often, deviate from the national recommendation of one Pap smear every 3 years for women 35-64 years of age. Ensuring compliance with national program guidelines is an essential step toward significantly reducing the burden of cervical cancer.

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.

In 2011, statewide newborn screening programs for critical congenital heart defects began in the United States, and subsequently screening has been implemented widely. In this review, we focus on data reports and collection efforts related to both prenatal diagnosis and newborn screening. Defect-specific, maternal, and geographic factors are associated with variations in prenatal detection, so newborn screening provides a population-wide safety net for early diagnosis. A new web-based repository is collecting information on newborn screening program policies, quality indicators related to screening programs, and specific case-level data on infants with these defects. Birth defects surveillance programs also collect data about critical congenital heart defects, particularly related to diagnostic timing, mortality, and services. Individuals from state programs, federal agencies, and national organizations will be interested in these data to further refine algorithms for screening in normal newborn nurseries, neonatal intensive care settings, and other special populations; and ultimately to evaluate the impact of screening on outcomes.

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.

Evaluating the information provision procedure about prenatal screening for Down syndrome, using informed decision-making as a quality-indicator. Questionnaire- and register-based surveys. Midwives associated with 59 midwifery practices completed process data for 6435 pregnancies. Pregnant women (n=510) completed questionnaires on informed decision-making. Midwives offered information to 98.5% of women; 62.6% of them wished to receive information, of these, 81.9% actually received information. Decision-relevant knowledge was adequate in 89.0% of responding women. Knowledge about Down syndrome was less adequate than knowledge about the screening program. Participants in the screening program had higher knowledge scores on Down syndrome and on the screening program than non-participants. Of the women who intended to participate (35.8%), 3.1% had inadequate knowledge. A total of 75.5% of women made an informed decision; 94.3% of women participating in the screening program, and 64.9% of women not participating. This quality assurance study showed high levels of informed decision-making and a relatively low participation rate in the national screening program for Down syndrome in the Netherlands. Knowledge of the Down syndrome condition needs to be improved. This evaluation may serve as a pilot study for quality monitoring studies at a national level. Copyright © 2011 Elsevier Ireland Ltd.

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) was established to provide low-income, uninsured, and underinsured women access to cancer screening and diagnostic services with the goal of increasing the early detection and prevention of breast and cervical cancer. Although this is a valuable resource for women who might not have the means to get screened otherwise, providing services at no cost, by itself, does not guarantee uptake of screening services. Public education and targeted outreach facilitate the critical link between public service programs and the communities they serve. The purpose of public education and outreach in the NBCCEDP is to increase the number of women who use breast and cervical cancer screening services by raising awareness, providing education, addressing barriers, and motivating women to complete screening exams and follow-up. Effective strategies focus on helping to remove structural, physical, interpersonal, financial, and cultural barriers; educate women about the importance of screening and inform women about the services available to them. This article provides an overview of the importance of public education and targeted outreach activities for cancer screening through community-based programs including examples from NBCCEDP grantees that highlight successes, challenges, and solutions, encountered when conducting these types of interventions.

There are conflicting views as to whether testing for biotinidase deficiency (BD) ought to be incorporated into universal newborn screening (NBS) programs. The aim of this study was to evaluate the cost-effectiveness of adding BD to the panel of conditions currently screened under the national NBS program in Spain. We used information from the regional NBS program for BD that has been in place in the Spanish region of Galicia since 1987. These data, along with other sources, were used to develop a cost-effectiveness decision model that compared lifetime costs and health outcomes of a national birth cohort of newborns with and without an early detection program. The analysis took the perspective of the Spanish National Health Service. Effectiveness was measured in terms of quality-adjusted life years (QALYs). We undertook extensive sensitivity analyses around the main model assumptions, including a probabilistic sensitivity analysis. In the base case analysis, NBS for BD led to higher QALYs and higher health care costs, with an estimated incremental cost per QALY gained of $24,677. Lower costs per QALY gained were found when conservative assumptions were relaxed, yielding cost savings in some scenarios. The probability that BD screening was cost-effective was estimated to be >70% in the base case at a standard threshold value. This study indicates that NBS for BD is likely to be a cost-effective use of resources. Copyright © 2015 by the American Academy of Pediatrics.

Screening Program Reduced Melanoma Mortality at the Lawrence Livermore National Laboratory, 1984-1996

Schneider, MD, J S; II, PhD, D; MD, PhD, M

Worldwide incidence of cutaneous malignant melanoma has increased substantially, and no screening program has yet demonstrated reduction in mortality. We evaluated the education, self examination and targeted screening campaign at the Lawrence Livermore National Laboratory (LLNL) from its beginning in July 1984 through 1996. The thickness and crude incidence of melanoma from the years before the campaign were compared to those obtained during the 13 years of screening. Melanoma mortality during the 13-year period was based on a National Death Index search. Expected yearly deaths from melanoma among LLNL employees were calculated by using California mortality data matched by age,more » sex, and race/ethnicity and adjusted to exclude deaths from melanoma diagnosed before the program began or before employment at LLNL. After the program began, crude incidence of melanoma thicker than 0.75 mm decreased from 18 to 4 cases per 100,000 person-years (p = 0.02), while melanoma less than 0.75mm remained stable and in situ melanoma increased substantially. No eligible melanoma deaths occurred among LLNL employees during the screening period compared with a calculated 3.39 expected deaths (p = 0.034). Education, self examination and selective screening for melanoma at LLNL significantly decreased incidence of melanoma thicker than 0.75 mm and reduced the melanoma-related mortality rate to zero. This significant decrease in mortality rate persisted for at least 3 yr after employees retired or otherwise left the laboratory.« less

Economies of scale in federally-funded state-organized public health programs: results from the National Breast and Cervical Cancer Early Detection Programs

This study investigates the existence of economies of scale in the provision of breast and cervical cancer screening and diagnostic services by state National Breast and Cervical Cancer Early Detection Program (NBCCEDP) grantees. A translog cost function is estimated as a system with input factor share equations. The estimated cost function is then used to determine output levels for which average costs are decreasing (i.e., economies of scale exist). Data were collected from all state NBCCEDP programs and District of Columbia for program years 2006–2007, 2008–2009 and 2009–2010 (N =147). Costs included all programmatic and in-kind contributions from federal and non-federal sources, allocated to breast and cervical cancer screening activities. Output was measured by women served, women screened and cancers detected, separately by breast and cervical services for each measure. Inputs included labor, rent and utilities, clinical services, and quasi-fixed factors (e.g., percent of women eligible for screening by the NBCCEDP). 144 out of 147 program-years demonstrated significant economies of scale for women served and women screened; 136 out of 145 program-years displayed significant economies of scale for cancers detected. The cost data were self-reported by the NBCCEDP State programs. Quasi-fixed inputs were allowed to affect costs but not economies of scale or the share equations. The main analysis accounted for clustering of observations within State programs, but it did not make full use of the panel data. The average cost of providing breast and cervical cancer screening services decreases as the number of women screened and served increases. PMID:24326873

Demand for a wide array of colorectal cancer screening strategies continues to outpace supply. One strategy to reduce this deficit is to dramatically increase the number of primary care physicians who are trained and supportive of performing office-based colonoscopies or flexible sigmoidoscopies. This study evaluates the clinical and economic implications of training primary care physicians via family medicine residency programs to offer colorectal cancer screening services as an in-office procedure. Using previously established clinical and economic assumptions from existing literature and budget data from a local grant (2013), incremental cost-effectiveness ratios are calculated that incorporate the costs of a proposed national training program and subsequent improvements in patient compliance. Sensitivity analyses are also conducted. Baseline assumptions suggest that the intervention would produce 2394 newly trained residents who could perform 71,820 additional colonoscopies or 119,700 additional flexible sigmoidoscopies after ten years. Despite high costs associated with the national training program, incremental cost-effectiveness ratios remain well below standard willingness-to-pay thresholds under base case assumptions. Interestingly, the status quo hierarchy of preferred screening strategies is disrupted by the proposed intervention. A national overhaul of family medicine residency programs offering training for colorectal cancer screening yields satisfactory incremental cost-effectiveness ratios. However, the model places high expectations on primary care physicians to improve current compliance levels in the US. Copyright © 2016 Elsevier Inc. All rights reserved.

Retinopathy of prematurity (ROP) is the main cause of avoidable blindness in children in Mexico despite National ROP Guidelines and examination of preterm infants being a legal requirement. Objective. To assess coverage of ROP programs and their compliance with national guidelines. Study Design. Thirty-two neonatal intensive care units (NICUs) in five of the largest states were visited. Staff were interviewed to collect information on their ROP programs which were defined as (1) compliant, if National Guidelines for screening and treatment were followed, (2) noncompliant, if other approaches were used, or (3) no program. Results. Only 10 (31.2%) had fully compliant programs and 11 (34.4%) had no program. In the remaining 11 (34.4%) different screening criteria were used (7 units): screening was undertaken by an ophthalmologist in unsalaried time (4), was not undertaken in the NICU (2), and was undertaken by a neonatologist (1) and/or Avastin was used as first-line treatment (7). Poorer states had poorer programs. Conclusions. Despite legislation mandating eye examination of preterm births, many ROP programs in the largest cities in Mexico require improvement or need to be established. Prevention of blindness due to ROP needs to be prioritized in Mexico to control the epidemic of ROP blindness. PMID:26167494

AIM: To investigate the outcome and effectiveness of two screening programs, National Cancer Screening Program (NCSP) and opportunistic screening (OS), for the detection of gastric cancer. METHODS: A total of 45  654 subjects underwent upper endoscopy as part of the NCSP or OS at the Chung-Ang University Healthcare System in Korea between January 2007 and December 2010. The study population was comprised of subjects over the age of 40 years. More specifically, subjects who took part in the NCSP were Medicaid recipients and beneficiaries of the National Health Insurance Corporation. Still photographs from the endoscopies diagnosed as gastric cancer were reviewed by two experienced endoscopists. RESULTS: The mean age of the screened subjects was 55 years for men and 54 years for women. A total of 126 cases (0.28%) of gastric cancer were detected from both screening programs; 100 cases (0.3%) from NCSP and in 26 cases (0.2%) from OS. The proportion of early gastric cancer (EGC) detected in NCSP was higher than that in OS (74.0% vs 53.8%, P = 0.046). Among the 34  416 screenees in NCSP, 6585 (19.1%) underwent upper endoscopy every other year as scheduled. Among the 11  238 screenees in OS, 3050 (27.1%) underwent upper endoscopy at least once every two years during the study period. The detection rate of gastric cancer was found to be significantly higher during irregular follow-up than during regular follow-up in both screening programs (0.3% vs 0.2%, P = 0.036). A higher incidence of EGC than advanced gastric cancer was observed during regular follow-up compared with irregular follow-up. CONCLUSION: Compliance to the screening program is more important than the type of screening system used. PMID:23430471

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast and cervical cancer screening and diagnostic services to low-income and underserved women through a network of providers and health care organizations. Although the program serves women 40-64 years old for breast cancer screening and 21-64 years old for cervical cancer screening, the priority populations are women 50-64 years old for breast cancer and women who have never or rarely been screened for cervical cancer. From 1991 through 2011, the NBCCEDP provided screening and diagnostic services to more than 4.3 million women, diagnosing 54,276 breast cancers, 2554 cervical cancers, and 123,563 precancerous cervical lesions. A critical component of providing screening services is to ensure that all women with abnormal screening results receive appropriate and timely diagnostic evaluations. Case management is provided to assist women with overcoming barriers that would delay or prevent follow-up care. Women diagnosed with cancer receive treatment through the states' Breast and Cervical Cancer Treatment Programs (a special waiver for Medicaid) if they are eligible. The NBCCEDP has performance measures that serve as benchmarks to monitor the completeness and timeliness of care. More than 90% of the women receive complete diagnostic care and initiate treatment less than 30 days from the time of their diagnosis. Provision of effective screening and diagnostic services depends on effective program management, networks of providers throughout the community, and the use of evidence-based knowledge, procedures, and technologies.

The resolution of policy questions relating to medical genetic screening programs will not be without considerable difficulty. Examples include such issues as the optimal degree of screening program expansion, the relative values of screening for different genetic diseases, the appropriate sources of program funding (public vs. private), and the relative value of funding expanded genetic screening programs vs. research directed toward elimination of genetic traits themselves. Information on the net impact of the relevant alternatives is greatly needed, and this need will increase if the National Genetics Act receives funding approval. We have provided what is hopefully a contribution toward this end. While our analysis pertains to a specific disease and a specific screening program for that disease, the methodology is readily generalizable to other genetic diseases, as well as programs of any size or structure. Hopefully, this will serve to stimulate further research efforts that we believe are needed for the objective consideration of resource allocation alternatives. PMID:418675

Objective The rates of participation in the Korean nationwide cervical cancer screening program and the rates of abnormal test results were determined. Methods The database of the National Health Insurance Service (NHIS) was used during the study period (2009–2014). Results The participation rate increased from 41.10% in 2009 to 51.52% in 2014 (annual percentage change, 4.126%; 95% confidence interval [CI]=2.253–6.034). During the study period, women ≥70 years of age had the lowest rate of participation (range, 21.7%–31.9%) and those 30–39 years of age the second-lowest (27.7%–44.9%). The participation rates of National Health Insurance beneficiaries (range, 48.6%–52.5%) were higher than those of Medical Aid Program (MAP) recipients (29.6%–33.2%). The rates of abnormal results were 0.65% in 2009 and 0.52% in 2014, with a decreasing tendency in all age groups except the youngest (30–39 years). Every year the abnormal result rates tended to decrease with age, from the age groups of 30–39 years to 60–69 years but increased in women ≥70 years of age. The ratio of patients with atypical squamous cells of undetermined significance compared with those with squamous intraepithelial lesions increased from 2.71 in 2009 to 4.91 in 2014. Conclusion Differences related to age and occurring over time were found in the rates of participation and abnormal results. Further efforts are needed to encourage participation in cervical cancer screening, especially for MAP recipients, elderly women and women 30–39 years of age. Quality control measures for cervical cancer screening programs should be enforced consistently. PMID:28657224

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast and cervical cancer screens to low-income, uninsured, and underinsured women. We describe the number and proportion of women eligible for cervical cancer screening services and the proportion of eligible women screened over the period 1997-2012. Low-income, uninsured, and underinsured women aged 18-64 years who have not had a hysterectomy are eligible for cervical cancer screening through the NBCCEDP. We estimated the number of low-income, uninsured women using data from the US Census Bureau. We adjusted our estimates for hysterectomy status using the National Health Interview Survey and the Behavioral Risk Factor Surveillance System. We used data from the NBCCEDP to describe the number of women receiving NBCCEDP-funded screening and calculated the proportion of eligible women who received screening through the NBCCEDP at the national level (by age group, race/ethnicity) and at the state level by age group. We used the Medical Expenditure Panel Survey to estimate the proportion of NBCCEDP-eligible women who were screened outside the NBCCEDP and the proportion that are not screened. We estimate that in 2010-2012, 705,970 women aged 18-64 years, 6.5 % (705,970 of 9.8 million) of the eligible population, received NBCCEDP-funded Pap tests. We estimate that 60.2 % of eligible women aged 18-64 years were screened outside the NBCCEDP and 33.3 % were not screened. The NBCCEDP provided 623,603 screens to women aged 40-64 years, an estimated 16.5 % of the eligible population, and 83,660 screens to women aged 18-39 years, representing an estimated 1.2 % of the eligible population. The estimated proportions of eligible women screened in each state ranged from 1.5 to 32.7 % and 5 % to 73.2 % among the 18-64 and 40-64 years age groups, respectively. Changes in the proportion of eligible women screened over the study period were nonsignificant. Although the program provided cervical screening to over 700,000 women between 2010 and 2012, it served a small percent of those eligible. The proportion of women screened varied substantially across age groups, racial/ethnic groups, and states. Many low-income, uninsured women are not being screened.

Primary HPV testing versus cytology-based cervical screening in women in Australia vaccinated for HPV and unvaccinated: effectiveness and economic assessment for the National Cervical Screening Program.

Australia's National Cervical Screening Program currently recommends cytological screening every 2 years for women aged 18-69 years. Human papillomavirus (HPV) vaccination was implemented in 2007 with high population coverage, and falls in high-grade lesions in young women have been reported extensively. This decline prompted a major review of the National Cervical Screening Program and new clinical management guidelines, for which we undertook this analysis. We did effectiveness modelling and an economic assessment of potential new screening strategies, using a model of HPV transmission, vaccination, natural history, and cervical screening. First, we evaluated 132 screening strategies, including those based on cytology and primary HPV testing. Second, after a recommendation was made to adopt primary HPV screening with partial genotyping and direct referral to colposcopy of women positive for HPV16/18, we evaluated the final effect of HPV screening after incorporating new clinical guidelines for women positive for HPV. Both evaluations considered both unvaccinated and vaccinated cohorts. Strategies entailing HPV testing every 5 years and either partial genotyping for HPV16/18 or cytological co-testing were the most effective. One of the most effective and cost-effective strategies comprised primary HPV screening with referral of women positive for oncogenic HPV16/18 direct to colposcopy, with reflex cytological triage for women with other oncogenic types and direct referral for those in this group with high-grade cytological findings. After incorporating detailed clinical guidelines recommendations, this strategy is predicted to reduce cervical cancer incidence and mortality by 31% and 36%, respectively, in unvaccinated cohorts, and by 24% and 29%, respectively, in cohorts offered vaccination. Furthermore, this strategy is predicted to reduce costs by up to 19% for unvaccinated cohorts and 26% for cohorts offered vaccination, compared with the current programme. Primary HPV screening every 5 years with partial genotyping is predicted to be substantially more effective and potentially cost-saving compared with the current cytology-based screening programme undertaken every 2 years. These findings underpin the decision to transition to primary HPV screening with partial genotyping in the Australian National Cervical Screening Program, which will occur in May, 2017.

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.

The Diabetic Retinopathy Screening Workflow

Complications of diabetes mellitus, namely diabetic retinopathy and diabetic maculopathy, are the leading cause of blindness in working aged people. Sufferers can avoid blindness if identified early via retinal imaging. Systematic screening of the diabetic population has been shown to greatly reduce the prevalence and incidence of blindness within the population. Many national screening programs have digital fundus photography as their basis. In the past 5 years several techniques and adapters have been developed that allow digital fundus photography to be performed using smartphones. We review recent progress in smartphone-based fundus imaging and discuss its potential for integration into national systematic diabetic retinopathy screening programs. Some systems have produced promising initial results with respect to their agreement with reference standards. However further multisite trialling of such systems’ use within implementable screening workflows is required if an evidence base strong enough to affect policy change is to be established. If this were to occur national diabetic retinopathy screening would, for the first time, become possible in low- and middle-income settings where cost and availability of trained eye care personnel are currently key barriers to implementation. As diabetes prevalence and incidence is increasing sharply in these settings, the impact on global blindness could be profound. PMID:26596630

To evaluate established opioid addiction treatment programs that use traditional healing in combination with buprenorphine-naloxone maintenance treatment in 6 First Nations communities in the Sioux Lookout region of northwestern Ontario. Retrospective cohort study. Six First Nations communities in northwestern Ontario. A total of 526 First Nations participants in opioid-dependence treatment programs. Buprenorphine-naloxone substitution therapy and First Nations healing programming. Retention rates and urine drug screening (UDS) results. Treatment retention rates at 6, 12, and 18 months were 84%, 78%, and 72%, respectively. We estimate that the rate at 24 months will also be more than 70%. The UDS programming varied and was implemented in only 1 community. Initially urine testing was voluntary and it then became mandatory. Screening with either method found the proportion of urine samples with negative results for illicit opioids ranged between 84% and 95%. The program's treatment retention rates and negative UDS results were higher than those reported for most methadone and buprenorphine-naloxone programs, despite a patient population where severe posttraumatic stress disorder is endemic, and despite the programs' lack of resources and addiction expertise. Community-based programs like these overcome the initial challenge of cultural competence. First Nations communities in other provinces should establish their own buprenorphinenaloxone programs, using local primary care physicians as prescribers. Sustainable core funding is needed for programming, long-term aftercare, and trauma recovery for such initiatives. Copyright© the College of Family Physicians of Canada.

The author describes the current health state of the Hungarian population in terms of cancer mortality and morbidity. Based on the comparative analysis of national and international, mainly European, data he describes the unfavourable Hungarian indices trying to identify their causes and the possible breaking free from them, as well. The greatest potential lies in the organised, continuous screenings within the frame of "Johan Béla National Programme of the Decade of Health". Since tumour diseases pose severe and alarming problems in national health care the reduction of extremely high mortality in three tumour localisation (cervix uteri, breast and colorectum) by regular screenings is absolutely justified.

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.

Newborn screening policy in the United Kingdom & the United States: two different communities of practice.

PubMed

Patch, Christine

2006-01-01

Newborn screening is a rapidly developing area driven by both technological advances and public pressure. If they are not yet, all nurses working with mothers and children will soon be involved with implementing newborn-screening programs, and it is therefore important that they appreciate both the benefits and potential harms of such programs. In the United Kingdom, policy regarding the implementation of newborn-screening programs is developed at national level, and consideration of the introduction of new tests is subject to a formalized evaluation framework. In the United States, by contrast, each state develops its own screening program. Knowledge of developments in newborn screening in different countries that have diverse types of healthcare systems helps to inform nurses about the totality of healthcare for newborns, and assists them in becoming more knowledgeable about how international standards differ from those in the United States.

The purpose of this study was to determine the national training practices of speech-language pathology graduate programs in outer and middle ear screening. Directors of all American Speech-Language-Hearing Association-accredited speech-language pathology graduate programs (N = 254; Council on Academic Accreditation in Audiology and Speech-Language Pathology, 2013) were surveyed on instructional formats in outer and middle ear screening. The graduate speech-language pathology program survey yielded 84 (33.1%) responses. Results indicated that some programs do not provide any training in the areas of conventional screening otoscopy using a handheld otoscope (15.5%; n = 13) or screening tympanometry (11.9%; n = 10), whereas close to one half (46.4%; n = 39) reported no training in screening video otoscopy. Outcomes revealed that approximately one third or more of speech-language pathology graduate programs do not provide experiential opportunities in screening handheld otoscopy (36.9%) or tympanometry (32.1%), and most (78.6%) do not provide experiential opportunities in video otoscopy. The implication from the graduate speech-language pathology program survey findings is that some speech-language pathologists will graduate from academic programs without the acquired knowledge or experiential learning required to establish skill in 1 or more areas of screening otoscopy and tympanometry. Graduate speech-language pathology programs should consider appropriate training opportunities for students to acquire and demonstrate skill in outer and middle ear screening.

Stigmatization of carrier status: social implications of heterozygote genetic screening programs.

Possible latent psychological and social consequences ensuing from genetic screening programs need to be investigated during the planning phase of national genetic screening programs. The relatively few studies which have been performed to determine psychological, social, and economic consequences resulting from a genetic screening program are reviewed. Stigmatization of carrier-status, having major psychosocial implications in heterozygote genetic screening programs, is discussed and related to Erving Goffman's work in the area of stigmatization. Questions are raised regarding the relationship between such variables as religiosity and sex of the individual and acceptance of the status of newly identified carrier of a mutant gene. Severity of the deleterious gene and visibility of the carrier status are two important factors to consider in an estimation of potential stigma. Specific implications are discussed for four genetic diseases: Tay-Sachs, Sickle-Cell Anemia, Huntington's disease and Hemophilia. PMID:152585

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.

Abstract Objective To evaluate established opioid addiction treatment programs that use traditional healing in combination with buprenorphine-naloxone maintenance treatment in 6 First Nations communities in the Sioux Lookout region of northwestern Ontario. Design Retrospective cohort study. Setting Six First Nations communities in northwestern Ontario. Participants A total of 526 First Nations participants in opioid-dependence treatment programs. Intervention Buprenorphine-naloxone substitution therapy and First Nations healing programming. Main outcome measures Retention rates and urine drug screening (UDS) results. Results Treatment retention rates at 6, 12, and 18 months were 84%, 78%, and 72%, respectively. We estimate that the rate at 24 months will also be more than 70%. The UDS programming varied and was implemented in only 1 community. Initially urine testing was voluntary and it then became mandatory. Screening with either method found the proportion of urine samples with negative results for illicit opioids ranged between 84% and 95%. Conclusion The program’s treatment retention rates and negative UDS results were higher than those reported for most methadone and buprenorphine-naloxone programs, despite a patient population where severe posttraumatic stress disorder is endemic, and despite the programs’ lack of resources and addiction expertise. Community-based programs like these overcome the initial challenge of cultural competence. First Nations communities in other provinces should establish their own buprenorphinenaloxone programs, using local primary care physicians as prescribers. Sustainable core funding is needed for programming, long-term aftercare, and trauma recovery for such initiatives. PMID:28209683

Although national-level organized cancer screening programs have reduced barriers to screening for people of low socioeconomic status, barriers to early screening remain. Our aim was to determine the diffusion pattern and identify the factors associated with early participation in stomach and breast cancer screening programs. The study population was derived from the Korean National Cancer Screening Survey, conducted in 2007. A stratified random sample of people aged 40 years and older from a nationwide population-based database was gathered in Korea (n=1,517) in 2007. Time of participation in early screening was defined as the number of years that had elapsed between the participant's 30th birthday and the age at first screening. Significant differences were observed in the probability of adopting stomach and breast cancer screening in relation to education, household income, and job level. Results from Cox's proportional hazard model indicated that higher household income was significantly associated with an increased probability of adopting stomach cancer screening earlier (p<0.05), and people with high household incomes were more likely to adopt breast cancer screening earlier than were those with incomes under US$1,500 per month (p<0.01). When considered at a significance level of 0.1, we found that the most highly educated women were more likely than the least educated to be screened early. Despite organized governmental screening programs, there are still inequalities in the early adoption of cancer screening. The results of this study also suggest that inequalities in early adoption may affect participation in regular screening. Copyright © 2010 Elsevier Ltd. All rights reserved.

2003-01-01

Various centers around the world have implemented and evaluated universal hearing screening programs as a response to the US National Institute of Health policy statement on early identification of hearing loss. Several well conducted clinical trials have been devised to examine and evaluate various factors relevant to establishing a UNHS program. This paper aims to describe some of these factors and analyze their applications and implications for a UNHS program for a developing country in the Asia-Pacific Region. Specifically, three main issues will be discussed: hospital vs community based programs, choice of technology, and choice of screening protocol.

Cervical cancer remains the most common malignancy in women living in low- and middle-income countries, despite the decline of the disease in countries where cervical cytology screening programs have been implemented. To review the current incidence of cervical cancer in low-resource countries, the availability and types of screening programs, and the treatment options. Literature review through PubMed, Internet search, and personal communication. Although data are incomplete, available figures confirm that the rate of cervical cancer deaths and the availability of cervical cancer screening programs are inversely proportional and vary, in general, by the wealth of the nation. Despite the success of cervical cytology screening, many major health care organizations have abandoned screening by cytology in favor of direct visualization methods with immediate treatment of lesions by cryotherapy provided by trained, nonmedical personnel.

A disease-specific Medicaid expansion for women. The Breast and Cervical Cancer Prevention and Treatment Act of 2000.

Lantz, Paula M; Weisman, Carol S; Itani, Zena

2003-01-01

The Breast and Cervical Cancer Prevention and Treatment Act of 2000 (BCCPTA) allows states the option of extending Medicaid eligibility to women diagnosed with breast or cervical cancer through a large federal screening program that does not include resources for treatment. Using qualitative data from interviews with 22 key informants and other sources, we present an analysis of the history and passage of the BCCPTA as a policy response to a perceived "treatment gap" in a national screening program. The results suggest that organizational policy entrepreneurs-primarily the National Breast Cancer Coalition-constructed an effective problem definition (that the government screening program was "unethical" and "broken") with a viable policy solution (an optional disease-specific Medicaid expansion), and pushed this proposal through a policy window opened by a budget surplus and an election year in which women's health issues had broad bipartisan appeal.

The Diabetic Retinopathy Screening Workflow: Potential for Smartphone Imaging.

Complications of diabetes mellitus, namely diabetic retinopathy and diabetic maculopathy, are the leading cause of blindness in working aged people. Sufferers can avoid blindness if identified early via retinal imaging. Systematic screening of the diabetic population has been shown to greatly reduce the prevalence and incidence of blindness within the population. Many national screening programs have digital fundus photography as their basis. In the past 5 years several techniques and adapters have been developed that allow digital fundus photography to be performed using smartphones. We review recent progress in smartphone-based fundus imaging and discuss its potential for integration into national systematic diabetic retinopathy screening programs. Some systems have produced promising initial results with respect to their agreement with reference standards. However further multisite trialling of such systems' use within implementable screening workflows is required if an evidence base strong enough to affect policy change is to be established. If this were to occur national diabetic retinopathy screening would, for the first time, become possible in low- and middle-income settings where cost and availability of trained eye care personnel are currently key barriers to implementation. As diabetes prevalence and incidence is increasing sharply in these settings, the impact on global blindness could be profound. © 2015 Diabetes Technology Society.

To describe recent trends in the prevalence of cytologic patterns of the vaginal flora (koilocytosis, Trichomonas, dys-bacteriosis, Candida, Gardnerella, Actinomyces, Chlamydia trachomatis) over the last decade. From 1996 to 2005 > 500,000 cervical smears were screened in the context of the Dutch national screening program on a 5-year basis. Data from the first screening period were compared with those of the second screening period. Prevalences differed from 34.8 for dysbacteriosis to 0.2 for C trachomatis. Bacterial imbalance (dysbacteriosis, unequivocal Gardnerella and Trichomonas) showed a decline in all age groups. Cases of human papillomavirus (HPV)-related koilocytosis have dramatically increased among young women (30 and 35 years). Bacterial imbalance of the vaginal flora has significantly decreased during the past decade in all age cohorts. Campaigns on consciousness of vaginal hygiene might have contributed to this amazing effect. We ought to be concerned about the increase in HPV-related koilocytosis.

Purpose The National Cancer Screening Program (NCSP) in Korea supports cancer screening for stomach, liver, colorectal, breast, and cervical cancer. This study was conducted to assess trends in participation rates among Korean men and women invited to undergo screening via the NCSP as part of an effort to guide future implementation of the program in Korea. Materials and Methods Data from the NCSP for 2002 to 2012 were used to calculate annual participation rates with 95% confidence intervals (CI) by sex, insurance status, and age group for stomach, liver, colorectal, breast, and cervical cancer screening. Results In 2012, participation rates for stomach, liver, colorectal, breast, and cervical cancer screening were 47.3%, 25.0%, 39.5%, 51.9%, and 40.9%, respectively. The participation rates increased annually by 4.3% (95% CI, 4.0 to 4.6) for stomach cancer, 3.3% (95% CI, 2.5 to 4.1) for liver cancer, 4.1% (95% CI, 3.2 to 5.0) for colorectal cancer, 4.6% (95% CI, 4.1 to 5.0) for breast cancer, and 0.9% (95% CI, –0.7 to 2.5) for cervical cancer from 2002 to 2012. Conclusion Participant rates for the NCSP for the five above-mentioned cancers increased annually from 2002 to 2012. PMID:27857022

Many of the countries in the Asia Pacific Region, particularly those with depressed and developing economies, are just initiating newborn screening programs for selected metabolic and other congenital disorders. The cultural, geographic, language, and economic differences that exist throughout the region add to the challenges of developing sustainable newborn screening systems. There are currently more developing programs than developed programs within the region. Newborn screening activities in the Asia Pacific Region are particularly important since births there account for approximately half of the world's births. To date, there have been two workshops to facilitate formation of the Asia Pacific Newborn Screening Collaboratives. The 1st Workshop on Consolidating Newborn Screening Efforts in the Asia Pacific Region occurred in Cebu, Philippines, on March 30-April 1, 2008, as a satellite meeting to the 7th Asia Pacific Conference on Human Genetics. The second workshop was held on June 4-5, 2010, in Manila, Philippines. Workshop participants included key policy-makers, service providers, researchers, and consumer advocates from 11 countries with 50% or less newborn screening coverage. Expert lectures included experiences in the United States and the Netherlands, international quality assurance activities and ongoing and potential research activities. Additional meeting support was provided by the U.S. National Institutes of Health, the Centers for Disease Control and Prevention, the U.S. National Newborn Screening and Genetics Resource Center, the International Society for Neonatal Screening, and the March of Dimes. As part of both meeting activities, participants shared individual experiences in program implementation with formal updates of screening information for each country. This report reviews the activities and country reports from two Workshops on Consolidating Newborn Screening Efforts in the Asia Pacific Region with emphasis on the second workshop. It also updates the literature on screening activities and implementation/expansion challenges in the participating countries.

In 2005 through 2009, the Centers for Disease Control and Prevention (CDC) funded 5 sites to implement a colorectal cancer screening program for uninsured, low-income populations. These 5 sites composed a demonstration project intended to explore the feasibility of establishing a national colorectal cancer screening program through various service delivery models. A longitudinal, multiple case study was conducted to understand and document program implementation processes. Using metaphor as a qualitative analytic technique, evaluators identified stages of maturation across the programmatic life cycle. Analysis rendered a working theory of program development during screening implementation. In early stages, program staff built relationships with CDC and local partners around screening readiness, faced real-world challenges putting program policies into practice, revised initial program designs, and developed new professional skills. Midterm implementation was defined by establishing program cohesiveness and expanding programmatic reach. In later stages of implementation, staff focused on sustainability and formal program closeout, which prompted reflection about personal and programmatic accomplishments. Demonstration sites evolved through common developmental stages during screening implementation. Findings elucidate ways to target technical assistance to more efficiently move programs along their maturation trajectory. In practical terms, the time and cost associated with guiding a program to maturity may be potentially shortened to maximize return on investment for both organizations and clients receiving service benefits. © 2013 American Cancer Society.

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides mammograms and diagnostic services for low-income, uninsured women aged 40-64 years. Mammography facilities within the NBCCEDP gradually shifted from plain-film to digital mammography. The purpose of this study is to assess the impact of replacing film with digital mammography on health effects (deaths averted, life-years gained [LYG]); costs (for screening and diagnostics); and number of women reached. NBCCEDP 2010 data and data representative of the program's target population were used in two established microsimulation models. Models simulated observed screening behavior including different screening intervals (annual, biennial, irregular) and starting ages (40, 50 years) for white, black, and Hispanic women. Model runs were performed in 2012. The models predicted 8.0-8.3 LYG per 1,000 film screens for black women, 5.9-7.5 for white women, and 4.0-4.5 for Hispanic women. For all race/ethnicity groups, digital mammography had more LYG than film mammography (2%-4%), but had higher costs (34%-35%). Assuming a fixed budget, 25%-26% fewer women could be served, resulting in 22%-24% fewer LYG if all mammograms were converted to digital. The loss in LYG could be reversed to an 8%-13% increase by only including biennial screening. Digital could result in slightly more LYG than film mammography. However, with a fixed budget, fewer women may be served with fewer LYG. Changes in the program, such as only including biennial screening, will increase LYG/screen and could offset the potential decrease in LYG when shifting to digital mammography.

Screening programs for genetic diseases and characteristics have multiplied in the last 50 years. 'Genetic Screening: Programs, Principles, and Research' is the report of the Committee for the Study of Inborn Errors of Metabolism (SIEM Committee) commissioned by the Division of Medical Sciences of the National Research Council at the National Academy of Sciences in Washington, DC, published in 1975. The report is considered a classic in the field worldwide, therefore it was thought appropriate 30 years later to present the Committee's modus operandi and bring the Committee's recommendations to the attention of those involved in genetics, including organizational, educational, legal, and research aspects of genetic screening. The Committee's report anticipated many of the legal, ethical, economic, social, medical, and policy aspects of genetic screening. The recommendations are current, and future committees should be familiar with them. In 1975 the Committee stated: 'As new screening tests are devised, they should be carefully reviewed. If the experimental rate of discovery of new genetic characteristics means an accelerating rate of appearance of new screening tests, now is the time to develop the medical and social apparatus to accommodate what later on may otherwise turn out to be unmanageable growth.' What a prophetic statement that was. If the Committee's recommendations had been implemented on time, there would be today a federal agency in existence, responsive and responsible to carry out the programs and support research on various aspects of genetic screening, including implementation of a federal law that protects consumers from discrimination by their employers and the insurance industry on the basis of genetic information.

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) is the largest cancer screening program for low-income women in the United States. This study updates previous estimates of the costs of delivering preventive cancer screening services in the NBCCEDP. We developed a standardized web-based cost-assessment tool to collect annual activity-based cost data on screening for breast and cervical cancer in the NBCCEDP. Data were collected from 63 of the 66 programs that received funding from the Centers for Disease Control and Prevention during the 2006/2007 fiscal year. We used these data to calculate costs of delivering preventive public health services in the program. We estimated the total cost of all NBCCEDP services to be $296 (standard deviation [SD], $123) per woman served (including the estimated value of in-kind donations, which constituted approximately 15% of this total estimated cost). The estimated cost of screening and diagnostic services was $145 (SD, $38) per women served, which represented 57.7% of the total cost excluding the value of in-kind donations. Including the value of in-kind donations, the weighted mean cost of screening a woman for breast cancer was $110 with an office visit and $88 without, the weighted mean cost of a diagnostic procedure was $401, and the weighted mean cost per breast cancer detected was $35,480. For cervical cancer, the corresponding cost estimates were $61, $21, $415, and $18,995, respectively. These NBCCEDP cost estimates may help policy makers in planning and implementing future costs for various potential changes to the program. © 2014 American Cancer Society.

Results of the National Program of Breast Cancer Early Detection in Brod-Posavina County during the 2006-2012 period are presented. Response rate in two National Program cycles, cancers detected according to factors such as first and last menstruation, age at cancer detection, deliveries and mammography findings according to the Breast Imaging Reporting and Data System (BI-RADS) before diagnosis verification were analyzed. Data were obtained from the software connecting Public Health Institutes via Ministry of Health server and questionnaires filled out by the women presenting for screening and processed by the method of descriptive statistics. Mammography findings were classified according to the BI-RADS classification. In two National Program cycles during the 2006-2012 period, women aged 50-69 were called for mammography screening. In the first cycle, the response rate in Brod-Posavina County was 53.2%, with 71 cancers detected at a mean age of 61.3 years. In the second cycle, the response rate was 57.0%, with 44 cancers detected at a mean age of 62.5 years. In the first and second cycles, there were 21.1% and 14.3% of mammography findings requiring additional work-up (BI-RADS 0), respectively. Particular risk factors such as early menarche, late menopause, parity, positive family history and presence of benign breast lesions were not demonstrated in women with verified cancer. There was no increase in the incidence of breast cancer per 100,000 inhabitants in the Brod-Posavina County following implementation of the National Program. In conclusion, efforts should be focused on increasing public health awareness, ensuring appropriate professional staff engaged in screening, and improving medical care in order to reduce the time elapsed from establishing suspicion to confirming the diagnosis of breast cancer.

Privately-funded addiction treatment programs were surveyed to increase understanding of assessment and current treatment options for patients with co-occurring substance use and eating disorders. Data were collected from face-to-face interviews with program administrators of a nationally representative sample of 345 private addiction treatment programs. Although the majority of programs reported screening for eating disorders, programs varied in screening instruments used. Sixty-seven percent reported admitting cases of low severity. Twenty-one percent of programs attempt to treat eating disorders. These results highlight the need for education of addiction treatment professionals in assessment, referral and treatment of eating disorders. PMID:21477048

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) of the Centers for Disease Control and Prevention (CDC) is implemented through cooperative agreements with state health departments, US territories, and tribal health organizations (grantees). Grantees typically contract with clinicians and other providers to deliver breast and cervical cancer screening and diagnostic services. As required by the CDC, grantees report biannually a subset of patient and clinical level program data known as the Minimum Data Elements. Rigorous processes are in place to ensure the completeness and quality of program data collection. In this article, the authors describe the NBCCEDP data-collection processes and data management system and discusses how data are used for 1) program monitoring and improvement, 2) evaluation and research, and 3) policy development and analysis. They also provide 2 examples of how grantees use data to improve their performance. PMID:25099900

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.

The US National Cancer Institute's (NCI) Natural Product Repository is one of the world's largest, most diverse collections of natural products containing over 230,000 unique extracts derived from plant, marine, and microbial organisms that have been collected from biodiverse regions throughout the world. Importantly, this national resource is available to the research community for the screening of extracts and the isolation of bioactive natural products. However, despite the success of natural products in drug discovery, compatibility issues that make extracts challenging for liquid handling systems, extended timelines that complicate natural product-based drug discovery efforts and the presence of pan-assay interfering compounds have reduced enthusiasm for the high-throughput screening (HTS) of crude natural product extract libraries in targeted assay systems. To address these limitations, the NCI Program for Natural Product Discovery (NPNPD), a newly launched, national program to advance natural product discovery technologies and facilitate the discovery of structurally defined, validated lead molecules ready for translation will create a prefractionated library from over 125,000 natural product extracts with the aim of producing a publicly-accessible, HTS-amenable library of >1,000,000 fractions. This library, representing perhaps the largest accumulation of natural-product based fractions in the world, will be made available free of charge in 384-well plates for screening against all disease states in an effort to reinvigorate natural product-based drug discovery.

Work-related musculoskeletal pain, commonly referred to more specifically as musculoskeletal disorders or cumulative trauma disorders, has continued to occur despite efforts by employers, employees, health care providers, and the government to eradicate it. The National Institute for Occupational Safety and Health has encouraged employers to establish ergonomic prevention programs; however, many employers are concerned that screening, education, and focused attention on workplace pain will cause an increase in the number of OSHA 200 events and the incidence of workers' compensation claims. This prospective cohort study demonstrated that there was no increase in the number of OSHA 200 events and no increase in the incidence of workers' compensation claims after completion of an individual risk screening program that included education and employee awareness about work-related musculoskeletal pain. Incidence of cumulative trauma disorders has been most effectively reduced by use of individual risk-screening programs. Therefore, employers should be encouraged to develop and implement prevention programs that include individual risk screening.

IMPORTANCE Newborn screening for severe combined immunodeficiency (SCID) using assays to detect T-cell receptor excision circles (TRECs) began in Wisconsin in 2008, and SCID was added to the national recommended uniform panel for newborn screened disorders in 2010. Currently 23 states, the District of Columbia, and the Navajo Nation conduct population-wide newborn screening for SCID. The incidence of SCID is estimated at 1 in 100 000 births. OBJECTIVES To present data from a spectrum of SCID newborn screening programs, establish population-based incidence for SCID and other conditions with T-cell lymphopenia, and document early institution of effective treatments. DESIGN Epidemiological and retrospective observational study. SETTING Representatives in states conducting SCID newborn screening were invited to submit their SCID screening algorithms, test performance data, and deidentified clinical and laboratory information regarding infants screened and cases with nonnormal results. Infants born from the start of each participating program from January 2008 through the most recent evaluable date prior to July 2013 were included. Representatives from 10 states plus the Navajo Area Indian Health Service contributed data from 3 030 083 newborns screened with a TREC test. MAIN OUTCOMES AND MEASURES Infants with SCID and other diagnoses of T-cell lymphopenia were classified. Incidence and, where possible, etiologies were determined. Interventions and survival were tracked. RESULTS Screening detected 52 cases of typical SCID, leaky SCID, and Omenn syndrome, affecting 1 in 58 000 infants (95%CI, 1/46 000-1/80 000). Survival of SCID-affected infants through their diagnosis and immune reconstitution was 87%(45/52), 92%(45/49) for infants who received transplantation, enzyme replacement, and/or gene therapy. Additional interventions for SCID and non-SCID T-cell lymphopenia included immunoglobulin infusions, preventive antibiotics, and avoidance of live vaccines. Variations in definitions and follow-up practices influenced the rates of detection of non-SCID T-cell lymphopenia. CONCLUSIONS AND RELEVANCE Newborn screening in 11 programs in the United States identified SCID in 1 in 58 000 infants, with high survival. The usefulness of detection of non-SCID T-cell lymphopenias by the same screening remains to be determined. PMID:25138334

We used the results from the first three screening rounds of Bahcesehir Mammography Screening Project (BMSP), a 10-year (2009-2019) and the first organized population-based screening program implemented in a county of Istanbul, Turkey, to assess the potential cost-effectiveness of a population-based mammography screening program in Turkey. Two screening strategies were compared: BMSP (includes three biennial screens for women between 40-69) and Turkish National Breast Cancer Registry Program (TNBCRP) which includes no organized population-based screening. Costs were estimated using direct data from the BMSP project and the reimbursement rates of Turkish Social Security Administration. The life-years saved by BMSP were estimated using the stage distribution observed with BMSP and TNBCRP. A total of 67 women (out of 7234 screened women) were diagnosed with breast cancer in BMSP. The stage distribution for AJCC stages O, I, II, III, IV was 19.4%, 50.8%, 20.9%, 7.5%, 1.5% and 4.9%, 26.6%, 44.9%, 20.8%, 2.8% with BMSP and TNBCRP, respectively. The BMSP program is expected to save 279.46 life years over TNBCRP with an additional cost of $677.171, which implies an incremental cost-effectiveness ratio (ICER) of $2.423 per saved life year. Since the ICER is smaller than the Gross Demostic Product (GDP) per capita in Turkey ($10.515 in 2014), BMSP program is highly cost-effective and remains cost-effective in the sensitivity analysis. Mammography screening may change the stage distribution of breast cancer in Turkey. Furthermore, an organized population-based screening program may be cost-effective in Turkey and in other developing countries. More research is needed to better estimate life-years saved with screening and further validate the findings of our study.

Background Breast cancer is the most common cancer in Iranian women as is worldwide. Mammography screening has been introduced as a beneficial method for reducing mortality and morbidity of this disease. Objectives We developed an analytical model to assess the cost effectiveness of an organized mammography screening program in Iran for early detection of the breast cancer. Patients and Methods This study is an economic evaluation of mammography screening program among Iranian woman aged 40 - 70 years. A decision tree and Markov model were applied to estimate total quality adjusted life years (QALY) and lifetime costs. Results The results revealed that the incremental cost effectiveness ratio (ICER) of mammography screening in Iranian women in the first round was Int. $ 37,350 per QALY gained. The model showed that the ICER in the second and third rounds of screening program were Int. $ 141,641 and Int. $ 389,148 respectively. Conclusions Study results identified that mammography screening program was cost-effective in 53% of the cases, but incremental cost per QALY in the second and third rounds of screening are much higher than the accepted payment threshold of Iranian health system. Thus, evaluation of other screening strategies would be useful to identify more cost-effective program. Future studies with new national data can improve the accuracy of our finding and provide better information for health policy makers for decision making. PMID:27366315

Irreversible sequels of some genetic diseases can be prevented by neonatal screening. The aim of this paper was to verify the prevalence of diseases diagnosed by the National Program of Neonatal Screening (PNTN) in Maringá, Paraná, Brazil, between 2001 and 2006. This cross-sectional descriptive study included 20,529 newborn infants screened by that program. Out of those, 859 were re-examined, and 21 had the disease confirmed. Considering all screened newborn infants and the number of diagnostics per disease, the following disease prevalence was determine: phenylketonuria--1:20,529; congenital hypothyrodism--1:2,281; hemoglobinopahies--1:3,421; cystic fibrosis--1:10,264; and biotinidase deficiency--1:6,843. Understanding disease status and prevalence of newborns in a population allows the establishment and the improvement of public policies aimed at the children.

Background In 2009, the Chinese Ministry of Health recommended scale-up of routine neonatal hearing screening - previously performed primarily only in select urban hospitals - throughout the entire country. Methods A decision analytical model for a simulated population of all live births in China was developed to compare the costs and health effects of five mutually exclusive interventions: 1) universal screening using Otoacoustic Emission (OAE) and Automated Auditory Brainstem Response (AABR); 2) universal OAE; 3) targeted OAE and AABR; 4) targeted OAE; and 5) no screening. Disability-Adjusted Life Years (DALYs) were calculated for health effects. Results and Discussion Based on the cost-effectiveness and potential health outcomes, the optimal path for scale-up would be to start with targeted OAE and then expand to universal OAE and universal OAE plus AABR. Accessibility of screening, diagnosis, and intervention services significantly affect decision of the options. Conclusion In conclusion, to achieve cost-effectiveness and best health outcomes of the NHS program, the accessibility of screening, diagnosis, and intervention services should be expanded to reach a larger population. The results are thus expected to be of particular benefit in terms of the ‘rolling out’ of the national plan. PMID:23341887

Cancer is an important cause of premature death in low- and middle-income countries (LMIC). Two preventive tools are available that have the potential together to sharply decrease the impact of cervical cancer in LMIC. The combination of human papillomavirus (HPV) vaccination and cervical cancer screening within existing programs is possible. Although there is a great deal of concern about introducing and strengthening HPV prevention efforts in LMIC, recent projects have demonstrated feasibility. Thus, with appropriate prioritization and resources, HPV prevention can be introduced and scaled up. Comprehensive HPV prevention strategies, mainly those geared at preventing cervical cancer, should include both vaccination and screening. The integration of both screening and vaccination will save the most lives, and such strategies are endorsed by many international organizations. However, some vaccine and screening programs are financed almost entirely by special externally-based programs. These more closely resemble demonstration exercises than sustainable national programs. In order for successful demonstration projects to have a broad impact on prevention, sustainable national funding based on strong commitments is essential. There may be challenges to implementing HPV prevention programs, but none should be considered insurmountable. Many LMIC have successfully adopted an HPV prevention agenda despite prevailing pessimism. Failure to act on this issue can perpetuate inequity in sexually transmitted infection and cancer prevention.

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.

Quality assurance (QA) is a process that includes the systematic evaluation of a service, institution of improvements and ongoing evaluation to ensure that effective changes were made. QA is a fundamental component of any organized colorectal cancer screening program. However, it should play an equally important role in opportunistic screening. Establishing the processes and procedures for a comprehensive QA program can be a daunting proposition for an endoscopy unit. The present article describes the steps taken to establish a QA program at the Forzani & MacPhail Colon Cancer Screening Centre (Calgary, Alberta) - a colorectal cancer screening centre and nonhospital endoscopy unit that is dedicated to providing colorectal cancer screening-related colonoscopies. Lessons drawn from the authors' experience may help others develop their own initiatives. The Global Rating Scale, a quality assessment and improvement tool developed for the gastrointestinal endoscopy services of the United Kingdom's National Health Service, was used as the framework to develop the QA program. QA activities include monitoring the patient experience through surveys, creating endoscopist report cards on colonoscopy performance, tracking and evaluating adverse events and monitoring wait times.

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.

BACKGROUND The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) is the largest cancer screening program for low-income women in the United States. This study updates previous estimates of the costs of delivering preventive cancer screening services in the NBCCEDP. METHODS We developed a standardized web-based cost-assessment tool to collect annual activity-based cost data on screening for breast and cervical cancer in the NBCCEDP. Data were collected from 63 of the 66 programs that received funding from the Centers for Disease Control and Prevention during the 2006/2007 fiscal year. We used these data to calculate costs of delivering preventive public health services in the program. RESULTS We estimated the total cost of all NBCCEDP services to be $296 (standard deviation [SD], $123) per woman served (including the estimated value of in-kind donations, which constituted approximately 15% of this total estimated cost). The estimated cost of screening and diagnostic services was $145 (SD, $38) per women served, which represented 57.7% of the total cost excluding the value of in-kind donations. Including the value of in-kind donations, the weighted mean cost of screening a woman for breast cancer was $110 with an office visit and $88 without, the weighted mean cost of a diagnostic procedure was $401, and the weighted mean cost per breast cancer detected was $35,480. For cervical cancer, the corresponding cost estimates were $61, $21, $415, and $18,995, respectively. CONCLUSIONS These NBCCEDP cost estimates may help policy makers in planning and implementing future costs for various potential changes to the program. PMID:25099904

The objectives of this paper are: (1) to study the feasibility and relative benefits of integrating the prevention of parent-to-child transmission (PPTCT) component of the National AIDS Control Program with the maternal and child health component of the National Rural Health Mission (NRHM) by offering HIV screening at the primary healthcare level; and (2) to estimate the incremental cost-effectiveness ratio to understand whether the costs are commensurate with the benefits. The intervention included advocacy with political, administrative/health heads, and capacity building of health staff in Satara district, Maharashtra, India. The intervention also conducted biannual outreach activities at primary health centers (PHCs)/sub-centers (SCs); initiated facility-based integrated counseling and testing centers (FICTCs) at all round-the-clock PHCs; made the existing FICTCs functional and trained PHC nurses in HIV screening. All "functional" FICTCs were equipped to screen for HIV and trained staff provided counseling and conducted HIV testing as per the national protocol. Data were collected pre- and post- integration on the number of pregnant women screened for HIV, the number of functional FICTCs and intervention costs. Trend analyses on various outcome measures were conducted. Further, the incremental cost-effectiveness ratio per pregnant woman screened was calculated. An additional 27% of HIV-infected women were detected during the intervention period as the annual HIV screening increased from pre- to post-intervention (55% to 79%, p < 0.001) among antenatal care (ANC) attendees under the NRHM. A greater increase in HIV screening was observed in PHCs/SCs. The proportions of functional FICTCs increased from 47% to 97% (p < 0.001). Additionally, 93% of HIV-infected pregnant women were linked to anti-retroviral therapy centers; 92% of mother-baby pairs received Nevirapine; and 89% of exposed babies were enrolled for early infant diagnosis. The incremental cost-effectiveness ratio was estimated at INR 44 (less than 1 US$) per pregnant woman tested. Integrating HIV screening with the broader Rural Health Mission is a promising opportunity to scale up the PPTCT program. However, advocacy, sensitization, capacity building and the judicious utilization of available resources are key to widening the reach of the PPTCT program in India and elsewhere.

To address the implementation of the National Newborn Screening Program (NBS) in Saudi Arabia and stratify the incidence of the screened disorders. A retrospective study conducted between 1 August 2005 and 31 December 2012, total of 775 000 newborns were screened from 139 hospitals distributed among all regions of Saudi Arabia. The NBS Program screens for 16 disorders from a selective list of inborn errors of metabolism (IEM) and endocrine disorders. Heel prick dry blood spot samples were obtained from all newborns for biochemical and immunoassay testing. Recall screening testing was performed for Initial positive results and confirmed by specific biochemical assays. A total of 743 cases were identified giving an overall incidence of 1:1043. Frequently detected disorders nationwide were congenital hypothyroidism and congenital adrenal hyperplasia with an incidence of 1:7175 and 1:7908 correspondingly. The highest incidence among the IEM was propionic acidaemia with an incidence rate of 1:14 000. The article highlights the experience of the NBS Program in Saudi Arabia and providing data on specific regional incidences of all the screened disorders included in the programme; and showed that the incidence of these disorders is one of the highest reported so far world-wide. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

International Perspectives on Radiology in Preventive Screening.

Brus-Ramer, Marcel; Lexa, Frank J; Kassing, Pamela; McGinty, Geraldine

2016-11-01

Several years ago, the International Economics Committee of the ACR began a study of comparisons among nations regarding the practice of radiology. This article is the second in a series. The purpose here is to compare the use across countries of imaging modalities in the screening algorithms of a variety of common diseases. In conjunction with the initial study, this will allow radiologists to understand in greater detail how health system practices differ among a selected set of nations. In this study, a standardized survey was administered to committee members from 10 countries in the developed and developing world. As with the prior study, there were both striking differences and similarities, even among a small cohort of nations that are all (except India) members of the Organisation for Economic Co-operation and Development. For example, breast cancer screening with mammography involves similar radiographic techniques for screening evaluations and has similarly high levels of insurance coverage, but the recommended ages at initial screening and end of screening differ. Other diseases, such as lung cancer and abdominal aortic aneurysm, have variable, but overall lower, levels of estimated participation among surveyed countries and significantly lower insurance coverage. Although this data set relies on survey data from individual practitioners, it provides an important perspective of the role of radiology in screening programs. Given the increasing pressure from domestic and foreign governments to reign in health care costs, the comparative differences in screening programs, and especially their use of (often costly) imaging techniques, may be a harbinger for future health policy decisions in the United States and abroad.

This paper seeks to identify the prevalence of Phenylketonuria (PKU) in Arab countries, Turkey, and Iran. The study reviewed the existence of comprehensive national newborn screening programs and reported consanguinity rates. A computer based literature search was conducted using relevant keywords to retrieve studies conducted on PKU. A total of 34 articles were included. Prevalence was categorized based on the type of screening method used for PKU diagnoses. The prevalence of classical PKU diagnosed through a comprehensive national newborn screening program ranged from 0.005% to 0.0167%. The highest prevalence was reported in Turkey at 0.0167%, whereas the lowest prevalence was reported in the UAE, 0.005%. The findings of this review emphasize the need for the establishment of more efficient reporting systems in these countries that would help measure Disability-Adjusted Life Year (DALY) in order to estimate the overall societal burden of PKU.

Financing for newborn screening is different from virtually all other public health programs. All except 5 screening programs collect fees as the primary source of program funding. A fee-based approach to financing newborn screening has been adopted by most states, to ensure consistent funding for this critical public health activity. Two types of data are reported here, ie, primary data from a survey of 37 state public health agencies and findings from exploratory case studies from 7 states. Most of the programs that participated in this survey (73%) reported that their newborn screening funding increased between 2002 and 2005, typically through increased fees and to a lesser extent through Medicaid, Title V Maternal and Child Health Services Block Grant, and state general revenue funding. All of the responding states that collect fees (n = 31) use such funds to support laboratory expenses, and most (70%) finance short-term follow-up services and program management. Nearly one half (47%) finance longer-term follow-up services, case management, or family support beyond diagnosis. Other states (43%) finance genetic or nutritional counseling and formula foods or treatment. Regardless of the source of funds, the available evidence indicates that states are committed to maintaining their programs and securing the necessary financing for the initial screening through diagnosis. Use of federal funding is currently limited; however, pressure to provide dedicated federal funding would likely increase if national recommendations for a uniform newborn screening panel were issued.

However, colon cancer incidence and mortality is declining over the past decade owing to adoption of effective screening programs. Nevertheless, in some parts of the world, CRC incidence and mortality remain on the rise, likely due to factors including "westernized" diet, lifestyle, and lack of health-care infrastructure and resources. Participation and adherence to different national screening programs remain obstacles limiting the achievement of screening goals. Different modalities are available ranging from stool based tests to radiology and endoscopy with varying sensitivity and specificity. However, the availability of these tests is limited to areas with high economic resources. Recently, FDA approved a blood-based test (Epi procolon ® ) for CRC screening. This blood based test may serve to increase the participation and adherence rates. Hence, leading to increase in colon cancer detection and prevention. This article will discuss various CRC screening tests with a particular focus on the data regarding the new approved blood test. Finally, we will propose an algorithm for a simple cost-effective CRC screening program.

Screening for lung cancer with low-dose CT has evolved rapidly in recent years since the National Lung Screening Trial (NLST) results. Subsequent professional and governmental organization guidelines have shaped policy and reimbursement for the service. Increasingly available guidance describes eligible patients and components necessary for a high-quality lung cancer screening program; however, practical instruction and implementation experience is not widely reported. We launched a lung cancer screening program in the face of reimbursement and guideline uncertainties at a large academic health center. We report our experience with implementation, including challenges and proposed solutions. Initially, we saw less referrals than expected for screening, and many patients referred for screening did not clearly meet eligibility guidelines. We educated primary care providers and implemented system tools to encourage referral of eligible patients. Moreover, in response to the Centers for Medicare & Medicaid Services (CMS) final coverage determination, we report our programmatic adaptation to meet these requirements. In addition to the components common to all quality programs, individual health delivery systems will face unique barriers related to patient population, available resources, and referral patterns.

Colorectal cancer is one of the most common cancers in both men and women worldwide and a good candidate for screening programs. There are two modalities of colorectal cancer screening: (i) population-based screening and (ii) opportunistic screening. The first one is based on organized, well-coordinated, monitored and established programs with a systematic invitation covering the entire target population. In contrast, opportunistic screening tests are offered to people who are being examined for other reasons. Recently, a variety of colorectal cancer screening tests have become available; each country should make a choice, based on national demographics and resources, on the screening method to be used. Fecal occult blood test, especially the fecal immunochemical test, would be the best modality for decreasing colorectal cancer mortality through population-based screening. In contrast, if the aim includes the early detection of colorectal cancer and adenomas, endoscopic methods are more appropriate. © The Author 2015. Published by Oxford University Press.

2016-05-01

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.

2015-01-01

In 1990, Congress passed the Breast and Cervical Cancer Mortality Prevention Act because of increases in the number of low-income and uninsured women being diagnosed with breast cancer. This act authorized the Centers for Disease Control and Prevention (CDC) to establish the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) to provide high-quality and timely breast and cervical cancer screening and diagnostic services to low-income, uninsured women. The program started in 1991, and, in 1993, Congress amended the act to allow the CDC to fund American Indian and Alaska Native tribes and tribal organizations. By 1996, the program was providing cancer screening across the United States. To ensure appropriate delivery and monitoring of services, the program adopted detailed policies on program management, evidence-based guidelines for clinical services, a systematized clinical data system to track service quality, and key partnerships that expand the program’s reach. The NBCCEDP currently funds 67 programs, including all 50 states, the District of Columbia, 5 US territories, and 11 tribes or tribal organizations. PMID:25099896

"Heritage of Science" is a short video that highlights the Stockpile Stewardship program at Los Alamos National Laboratory. Stockpile Stewardship was conceived in the early 1990s as a national science-based program that could assure the safety, security, and effectiveness of the U.S. nuclear deterrent without the need for full-scale underground nuclear testing. This video was produced by Los Alamos National Laboratory for screening at the Lab's Bradbury Science Museum in Los Alamos, NM and is narrated by science correspondent Miles O'Brien.

Sustaining SBIRT in the wild: simulating revenues and costs for Screening, Brief Intervention and Referral to Treatment programs.

2017-02-01

To examine the conditions under which Screening, Brief Intervention and Referral to Treatment (SBIRT) programs can be sustained by health insurance payments. A mathematical model was used to estimate the number of patients needed for revenues to exceed costs. Three medical settings in the United States were examined: in-patient, out-patient and emergency department. Components of SBIRT were delivered by combinations of health-care practitioners (generalists) and behavioral health specialists. Practitioners in seven SBIRT programs who received grants from the US Substance Abuse and Mental Health Services Administration (SAMHSA). Program costs and revenues were measured using data from grantees. Patient flows were measured from administrative data and adjusted with prevalence and screening estimates from the literature. SBIRT can be sustained through health insurance reimbursement in out-patient and emergency department settings in most staffing mixes. To sustain SBIRT in in-patient programs, a patient flow larger than the national average may be needed; if that flow is achieved, the range of screens required to maintain a surplus is narrow. Sensitivity analyses suggest that the results are very sensitive to changes in the proportion of insured patients. Screening, Brief Intervention and Referral to Treatment programs in the United States can be sustained by health insurance payments under a variety of staffing models. Screening, Brief Intervention and Referral to Treatment programs can be sustained only in an in-patient setting with above-average patient flow (more than 2500 screens). Screening, Brief Intervention and Referral to Treatment programs in out-patient and emergency department settings can be sustained with below-average patient flows (fewer than 125 000 out-patient visits and fewer than 27 000 emergency department visits). © 2017 Society for the Study of Addiction.

IntroductionPerinatal mood and anxiety disorders (PMADs) are the most common complication of pregnancy and have been found to have long-term implications for both mother and child. In vulnerable patient populations such as those served at Denver Health, a federally qualified health center the prevalence of PMADs is nearly double the nationally reported rate of 15-20%. Nearly 17% of women will be diagnosed with major depression at some point in their lives and those numbers are twice as high in women who live in poverty. Women also appear to be at higher risk for depression in the child-bearing years. In order to better address these issues, an Integrated Perinatal Mental Health program was created to screen, assess, and treat PMADs in alignment with national recommendations to improve maternal-child health and wellness. This program was built upon a national model of Integrated Behavioral Health already in place at Denver Health. A multidisciplinary team of physicians, behavioral health providers, public health, and administrators was assembled at Denver Health, an integrated hospital and community health care system that serves as the safety net hospital to the city and county of Denver, CO. This team was brought together to create a universal screen-to-treat process for PMAD's in perinatal clinics and to adapt the existing Integrated Behavioral Health (IBH) model into a program better suited to the health system's obstetric population. Universal prenatal and postnatal depression screening was implemented at the obstetric intake visit, a third trimester prenatal care visit, and at the postpartum visit across the clinical system. At the same time, IBH services were implemented across our health system's perinatal care system in a stepwise fashion. This included our women's care clinics as well as the family medicine and pediatric clinics. These efforts occurred in tandem to support all patients and staff enabling a specially trained behavioral health provider (psychologists and L.C.S.W.'s) to respond immediately to any positive screen during or after pregnancy. In August 2014 behavioral health providers were integrated into the women's care clinics. In January 2015 universal screening for PMADs was implemented throughout the perinatal care system. Screening has improved from 0% of women screened at the obstetric care intake visit in August 2014 to >75% of women screened in August 2016. IBH coverage by a licensed psychologist or licensed clinical social worker exists in 100% of perinatal clinics as of January 2016. As well, in order to gain sustainability, the ability to bill same day visits as well as to bill, and be reimbursed for screening and assessment visits, continues to improve and provide for a model that is self-sustaining for the future. Implementation of a universal screening process for PMADs alongside the development of an IBH model in perinatal care has led to the creation of a program that is feasible and has the capacity to serve as a national model for improving perinatal mental health in vulnerable populations.

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.

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

Implications of newborn screening for nurses.

Newborn screening has dramatically decreased the morbidity and mortality associated with a wide range of heritable conditions. Continuing advances in screening technology and improvements in the effectiveness of treatment are driving the rapid expansion of newborn screening programs. In this article, we review issues in newborn screening care and opportunities for nurses and nursing faculty to provide education and conduct research to improve the impact of newborn screening. This article provides (a) an overview of current newborn screening activities, including how conditions are added to newborn screening panels and how implementation occurs at state and national levels; (b) a description of current controversies and ethical considerations; (c) a description of the roles of nurses in the newborn screening process; (d) suggestions for nursing education and research; and (e) a summary of expected future developments in newborn screening, including genome sequencing. Nurses are uniquely well suited to address the educational needs and future research in newborn screening because of the role that nurses play in the provision of direct clinical care and in population-based healthcare delivery. Newborn screening is a public health approach to the identification of rare but treatable conditions in early infancy. In the United States, as in other industrialized countries, newborn screening is rapidly expanding. Nurses, nurse educators, and nurse researchers are positioned to contribute to the field of newborn screening by assuring programs are implemented safely and effectively, by facilitating education of the nursing work force, and by developing and contributing to research programs in newborn screening. © 2013 Sigma Theta Tau International.

Expenditure and resource utilisation for cervical screening in Australia

PubMed Central

2012-01-01

Background The National Cervical Screening Program in Australia currently recommends that women aged 18–69 years are screened with conventional cytology every 2 years. Publicly funded HPV vaccination was introduced in 2007, and partly as a consequence, a renewal of the screening program that includes a review of screening recommendations has recently been announced. This study aimed to provide a baseline for such a review by quantifying screening program resource utilisation and costs in 2010. Methods A detailed model of current cervical screening practice in Australia was constructed and we used data from the Victorian Cervical Cytology Registry to model age-specific compliance with screening and follow-up. We applied model-derived rate estimates to the 2010 Australian female population to calculate costs and numbers of colposcopies, biopsies, treatments for precancer and cervical cancers in that year, assuming that the numbers of these procedures were not yet substantially impacted by vaccination. Results The total cost of the screening program in 2010 (excluding administrative program overheads) was estimated to be A$194.8M. We estimated that a total of 1.7 million primary screening smears costing $96.7M were conducted, a further 188,900 smears costing $10.9M were conducted to follow-up low grade abnormalities, 70,900 colposcopy and 34,100 histological evaluations together costing $21.2M were conducted, and about 18,900 treatments for precancerous lesions were performed (including retreatments), associated with a cost of $45.5M for treatment and post-treatment follow-up. We also estimated that $20.5M was spent on work-up and treatment for approximately 761 women diagnosed with invasive cervical cancer. Overall, an estimated $23 was spent in 2010 for each adult woman in Australia on cervical screening program-related activities. Conclusions Approximately half of the total cost of the screening program is spent on delivery of primary screening tests; but the introduction of HPV vaccination, new technologies, increasing the interval and changing the age range of screening is expected to have a substantial impact on this expenditure, as well as having some impact on follow-up and management costs. These estimates provide a benchmark for future assessment of the impact of changes to screening program recommendations to the costs of cervical screening in Australia. PMID:23216968

[How can the cost of screening for toxoplasmosis during pregnancy be reduced?].

PubMed

Ancelle, T; Yera, H; Talabani, H; Lebuisson, A; Thulliez, P; Dupouy-Camet, J

2009-12-01

A program of systematic serology screening for toxoplasmosis during pregnancy has been running in France since 1978. The program involves monthly follow-ups for all non-immune pregnant women. Due to the steady decline in the seroprevalence of toxoplasmosis, the cost of the program is steadily increasing. Current screening is based on the detection of IgG and IgM isotypes. The aim of this work was to estimate the benefit of replacing combined dosage of two isotypes, by an alternative strategy that detects total anti-Toxoplasma immunoglobulins. The rate of decreasing seroprevalence and the increasing burden on serological examinations was measured in a study population of pregnant women who were checked for toxoplasmosis by the parasitology laboratory of the Cochin Hospital, Paris. The increase in screening costs was estimated for the all-pregnant women and the expected benefits stemming from simply measuring total anti-Toxoplasma immunoglobulins compared to the double IgG-IgM assay were estimated. Between 1987 and 2008, the seroprevalence of toxoplasmosis measured at the Cochin hospital dropped from 70.8% to 48.6% with a 1.77% annual rate of decline. This downward trend is similar to that observed by the national perinatal surveys performed in 1995 and in 2003. As the number of non-immune women to follow-up each month is constantly increasing, the proportion of negative tests issued reached 87.6% in 2008. Extrapolating these results to the whole of France, we estimated that the number of required screening tests perform was increasing by 93,000 units per year with an additional associated cost of one million euros. Various alternative scenarios of antibody detection are proposed that could save between 40.2% and 48.4% of current screening costs. Replacement of combined dosage of IgG and IgM isotypes by determination of just total Ig would significantly reduce costs of toxoplasmosis screening for pregnant women, without effecting either the general strategy, or proven efficiency of the national program.

Sweden has not yet implemented a national screening program for colorectal cancer, but a nationwide study is ongoing; the Screening of Swedish Colons (SCREESCO). Previous research shows that the use of health care services, together with several health-related outcomes, is associated with an individual's level of health literacy. However, the relation between health literacy and participation in colorectal cancer screening has produced varying results reported within the few studies addressing this issue and therefore, further research is warranted. The aim was to explore health literacy and views about being invited to screening, among participants and non-participants in a national colorectal cancer screening program. They were randomly sampled to fecal immunochemical test or colonoscopy and a mixed methods approach was applied, using questionnaires, focus group discussions and interviews. The majority of individuals, whether they were participants or non-participants in the SCREESCO program, had an acceptable level of health literacy and no significant differences in health literacy levels between the groups were found. Participants expressed that it was important and appreciated to be able to choose information sources on an individual basis. Among non-participants, the importance of receiving invitations with a clear message that quickly draws one's attention was highlighted. However, both groups expressed a positive outlook towards the invitation. The mixed methods approach revealed that findings from interviews and focus group discussions corresponded to items in the health literacy scales. A majority of individuals displayed acceptable levels of health literacy, regardless of whether they chose to participate or not. Similarities between the groups were seen in the qualitative findings regarding views of the invitation. Currently, the SCREESCO invitation letter is distributed by regular mail, but in the future a more dynamic approach could be valuable to increase clarity in the message about importance of screening.

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.

Gastroscopy and colonoscopy are widely used for the early diagnosis of stomach and colorectal cancer. The present revision integrates recent data regarding previous quality indicators and novel indicators suggested for gastroscopy and colonoscopy procedures for the National Cancer Screening Program in Korea. The new indicators, developed by the Quality Improvement Committee of the Korean Society for Gastrointestinal Endoscopy, vary in the level of supporting evidence, and most are based solely on expert opinion. Updated indicators validated by clinical research were prioritized, but were chosen by expert consensus when such studies were absent. The resultant quality indicators were graded according to the levels of consensus and recommendations. The updated indicators will provide a relevant guideline for high-quality endoscopy. The future direction of quality indicator development should include relevant outcome measures and an evidence-based approach to support proposed performance targets.

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.

In 2008, a national human papillomavirus (HPV) immunization program using a bivalent vaccine against HPV types 16 and 18 was implemented in Scotland along with a national surveillance program designed to determine the longitudinal effects of vaccination on HPV infection at the population level. Each year during 2009–2013, the surveillance program conducted HPV testing on a proportion of liquid-based cytology samples from women undergoing their first cervical screening test for precancerous cervical disease. By linking vaccination, cervical screening, and HPV testing data, over the study period we found a decline in HPV types 16 and 18, significant decreases in HPV types 31, 33, and 45 (suggesting cross-protection), and a nonsignificant increase in HPV 51. In addition, among nonvaccinated women, HPV types 16 and 18 infections were significantly lower in 2013 than in 2009. Our results preliminarily indicate herd immunity and sustained effectiveness of the bivalent vaccine on virologic outcomes at the population level. PMID:26692336

To study the factors affecting a neurodevelopmental status of children with congenital hypothyroidism, diagnosed on national screening program. The study was performed in the Pediatric Endocrinology Department of Dr. Behcet Uz Children's Hospital between May 2012 and May 2013. Children with congenital hypothyroidism, aged between 24 and 36 months, diagnosed by national screening program were included in the study group. Healthy subjects at the same age group consisted of the control group. For the neurodevelopmental evaluation, Bayley Scale of Infant Development- II (BSID-II) was used. Factors possibly effective on neurodevelopment were evaluated. 42 patients and 40 healthy children (mean (SD) age, 29.4 (3.7) and 29.2 (3.5), respectively were included in the study. The mean MDI score [92.6 (7.07) vs 97.1 (9.69), P=0.14)] and the mean PDI score [97.8 (15.68) vs 99.1 (10.57), P=0.66)] in the study group and control group were not significantly different. Among the patient, 4.6% and 4.7% children were moderately retarded as per the MDI scores and PPI scores, respectively. The sex, socioeconomic status, birth weight, screening levels of TSH, severity of the congenital hypothyroidism, initiation time and the dosage of thyroid hormone replacement, length of the normalization period of TSH, and adherence to treatment were not found to affect the MDI and PDI scores of the patients. Some children with congenital hypothyrodism may have mild to moderate neurodevelopmental retardation, despite the early diagnosis and treatment, and thus need to be under regular follow-up for neurodevelopmental status.

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.

Cancer screening is a behavior that represents investment in future health. Such investment may depend on how much 'future' a person expects. The purpose of this study was to investigate the prospective association between perceived personal life expectancy and participation in fecal occult blood test screening for colorectal cancer (CRC) in a national program. Data were from interviews with 3975 men and women in the English Longitudinal Study of Ageing (ELSA) within the eligible age range for the national screening program (60 to 74 years). Perceived life expectancy was indexed as the individual's estimate of their chance of living another 10-15 years (exact time varied by age), assessed in 2008/2009. Participation in CRC screening from 2010 to 2012/2013 was assessed in 2012/2013. Logistic regression was used to estimate the association between perceived life expectancy and screening participation, adjusted for numeracy and known mortality risk factors. Overall, 71% of respondents (2817/3975) reported completing at least one fecal occult blood test (FOBt) during the follow-up. Screening uptake was 76% (1272/1683) among those who estimated their 10-15-year life expectancy as 75-100%, compared with 52% (126/243) among those who estimated theirs as 0-25% (adjusted OR 1.74, 95% CI 1.29-2.34). A longer perceived life expectancy is associated with greater likelihood of participating in CRC screening in England. However, half of people with a low perceived life expectancy still participated in screening. Given that CRC screening is recommended for adults with a remaining life expectancy of ≥10 years, future research should investigate how to communicate the aims of screening more effectively.

Newborn screening (NBS) programs are population-based public health programs and are uniquely financed footline compared with many other public health programs. Since they began more than 45 years ago, the financing issues have become more complex for NBS programs. Today, almost all programs have a portion of their costs paid by fees. The fee amounts vary from program to program, with little standardization in the way they are formulated, collected, or used. We previously surveyed 37 of the 51 dried blood spot screening programs throughout the United States, and confirmed an increasing dependence on NBS fees. In this study, we have collected responses from all 51 programs (100%), including updated responses from the original 37, and updated our fee listings. Comments from those surveyed indicated that the lack of a national standardized procedural coding system for NBS contributes to billing complexities. We suggest one coding possibility for discussion and debate for such a system. Differences in Medicaid interpretations may also contribute to financing inequities across NBS programs and there may be benefit from certain clarifications at the national level. Completed survey responses accounted for few changes in the conclusions of our original survey. We confirmed that 90 percent of all NBS programs have a fee paid by parents or a third party payer. Sixty-one percent reported receiving some funds from the Maternal and Child Health Services Title V block grant, 33 percent reported some funding from state general revenue/general public health appropriations; and 24 percent reported obtaining direct reimbursement from Medicaid (without passing through a third party). A majority of programs (63%) reported budget increases between 2002 and 2005, with increases primarily from fees (72%) and to a lesser extent from Medicaid, the Title V block grant, and state general revenues.

The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) data at our institution indicated that surgical mortality was significantly higher than expected. This study examines the effect of implementation of a strict, intensive preoperative screening and intervention process on postoperative mortality at our institution, as measured by the NSQIP. Carilion Roanoke Memorial Hospital (CRMH) is a 763-bed tertiary care hospital serving a population of one million people in southwest Virginia. Data were collected for NSQIP at CRMH from July 2007 to December 2012. In January 2010, a new preoperative process was implemented to include risk assessment and intervention for hypertension, cardiac disease, pulmonary disease, diabetes, renal disease, and obstructive sleep apnea. Before initiation of our preoperative program (July 2007 to January 2010), odds ratios (ORs) for 30-day mortality in general and vascular cases were significantly higher than expected (1.40, 1.43, 1.58, and 1.56 in successive reporting periods). Beginning with the first report after implementation of the preoperative screening program, CRMH showed a progressively decreasing OR for overall 30-day mortality (1.26, 1.19, 1.14, 0.86, 0.82, 0.84, 0.89) with similar reductions in both general (0.92) and vascular (0.92) surgery. The implementation of an intensive preoperative screening and intervention process in our institution was accompanied by a significant decrease in the 30-day mortality for general surgery and vascular procedures, as measured by the NSQIP.

Missed opportunities in educating Aboriginal Australians about bowel cancer screening: whose job is it anyway?

PubMed

Christou, Aliki; Thompson, Sandra C

2013-12-01

A culturally relevant educational flipchart targeting Aboriginal people was distributed across Western Australia to support education on bowel cancer screening and encourage participation in the National Bowel Cancer Screening Program. Respondents sampled from the flipchart distribution list were surveyed on the appropriateness, usefulness, and the extent to and manner in which they used the flipchart for educating Aboriginal clients. Despite praising the resource, few respondents used the flipchart as intended for various reasons, including the view that Aboriginal health education was the responsibility of Aboriginal health workers. Greater recognition by all health service providers is needed of their potential role in Aboriginal health education. Promoting a national health program of under-appreciated importance for a marginalised population is challenging. Effective utilisation of an educational tool is predicated on factors beyond its production quality and wide dissemination. Intended users require awareness of the underlying problem, and adequate time for and specific training in implementation of the tool.

Both incidence and mortality rates for prostate cancer are significantly higher in African American men than in white men. This report identifies community sites for the optimal recruitment of African American men into prostate cancer screening. A descriptive study was conducted, providing an educational program to 1369 African American men, 1264 of whom completed a survey on demographic data, prostate cancer knowledge, and prostate cancer screening history. The programs were offered at six different types of community sites, including various work sites, churches, housing projects, National Association for Advancement of Colored Persons (NAACP) sites, barber shops, and a state fairground. Free prostate cancer screening was offered to all participants. The advertised mass screening site (state fairground), the most common method used nationally to recruit African American men for cancer screening, was the least effective site, with only 16 men completing the survey. Of the 1264 men completing the survey at all community sites, 597 men (47%) did so at work sites and 438 (35%) did so at churches. Per site, the largest percentage of men who had never been screened was at work sites (n = 276, 46%) and NAACP sites (n = 22, 33.8%). The highest percentage of men who obtained free screening were at the state fairground (14 of 16), churches (256 of 438), and work sites (336 of 597). The most prostate cancers were detected at the housing projects, where 3 of 38 (7.9%) men who were screened received diagnoses of prostate cancer. To reduce prostate mortality rates in African American men, healthcare providers need to make a concerted effort to increase prostate cancer education and screening in this population. To be effective, recruitment of African American men must move from a provider/health site orientation to a consumer/community orientation. These findings indicate that recruitment strategies are more successful if efforts are based in the community or where a large number of African American men live and/or work. Because a history of screening has been shown to be a predictor for current participation, programs need to target men who have not had previous screening ever or within the last year. In addition, the large percentage of men recruited at work sites who had not been screened previously indicates an opportunity for collaboration with healthcare professionals in employee health programs. Efforts to increase participation in prostate cancer screening will be enhanced significantly by eliciting the active involvement of community leaders.

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.

Can screening and brief intervention lead to population-level reductions in alcohol-related harm?

PubMed Central

2012-01-01

A distinction is made between the clinical and public health justifications for screening and brief intervention (SBI) against hazardous and harmful alcohol consumption. Early claims for a public health benefit of SBI derived from research on general medical practitioners’ (GPs’) advice on smoking cessation, but these claims have not been realized, mainly because GPs have not incorporated SBI into their routine practice. A recent modeling exercise estimated that, if all GPs in England screened every patient at their next consultation, 96% of the general population would be screened over 10 years, with 70-79% of excessive drinkers receiving brief interventions (BI); assuming a 10% success rate, this would probably amount to a population-level effect of SBI. Thus, a public health benefit for SBI presupposes widespread screening; but recent government policy in England favors targeted versus universal screening, and in Scotland screening is based on new registrations and clinical presentation. A recent proposal for a national screening program was rejected by the UK National Health Service’s National Screening Committee because 1) there was no good evidence that SBI led to reductions in mortality or morbidity, and 2) a safe, simple, precise, and validated screening test was not available. Even in countries like Sweden and Finland, where expensive national programs to disseminate SBI have been implemented, only a minority of the population has been asked about drinking during health-care visits, and a minority of excessive drinkers has been advised to cut down. Although there has been research on the relationship between treatment for alcohol problems and population-level effects, there has been no such research for SBI, nor have there been experimental investigations of its relationship with population-level measures of alcohol-related harm. These are strongly recommended. In this article, conditions that would allow a population-level effect of SBI to occur are reviewed, including their political acceptability. It is tentatively concluded that widespread dissemination of SBI, without the implementation of alcohol control measures, might have indirect influences on levels of consumption and harm but would be unlikely on its own to result in public health benefits. However, if and when alcohol control measures were introduced, SBI would still have an important role in the battle against alcohol-related harm. PMID:23186309

Real-Time Monitoring and Evaluation of a Visual-Based Cervical Cancer Screening Program Using a Decision Support Job Aid.

2016-05-16

In many developing nations, cervical cancer screening is done by visual inspection with acetic acid (VIA). Monitoring and evaluation (M&E) of such screening programs is challenging. An enhanced visual assessment (EVA) system was developed to augment VIA procedures in low-resource settings. The EVA System consists of a mobile colposcope built around a smartphone, and an online image portal for storing and annotating images. A smartphone app is used to control the mobile colposcope, and upload pictures to the image portal. In this paper, a new app feature that documents clinical decisions using an integrated job aid was deployed in a cervical cancer screening camp in Kenya. Six organizations conducting VIA used the EVA System to screen 824 patients over the course of a week, and providers recorded their diagnoses and treatments in the application. Real-time aggregated statistics were broadcast on a public website. Screening organizations were able to assess the number of patients screened, alongside treatment rates, and the patients who tested positive and required treatment in real time, which allowed them to make adjustments as needed. The real-time M&E enabled by "smart" diagnostic medical devices holds promise for broader use in screening programs in low-resource settings.

Potential capacity of endoscopic screening for gastric cancer in Japan.

PubMed

Hamashima, Chisato; Goto, Rei

2017-01-01

In 2016, the Japanese government decided to introduce endoscopic screening for gastric cancer as a national program. To provide endoscopic screening nationwide, we estimated the proportion of increase in the number of endoscopic examinations with the introduction of endoscopic screening, based on a national survey. The total number of endoscopic examinations has increased, particularly in clinics. Based on the national survey, the total number of participants in gastric cancer screening was 3 784 967. If 30% of the participants are switched from radiographic screening to endoscopic screening, approximately 1 million additional endoscopic examinations are needed. In Japan, the participation rates in gastric cancer screening and the number of hospitals and clinics offering upper gastrointestinal endoscopy vary among the 47 prefectures. If the participation rates are high and the numbers of hospitals and clinics are small, the proportion of increase becomes larger. Based on the same assumption, 50% of big cities can provide endoscopic screening with a 5% increase in the total number of endoscopic examinations. However, 16.7% of the medical districts are available for endoscopic screening within a 5% increase in the total number of endoscopic examinations. Despite the Japanese government's decision to introduce endoscopic screening for gastric cancer nationwide, its immediate introduction remains difficult because of insufficient medical resources in rural areas. This implies that endoscopic screening will be initially introduced to big cities. To promote endoscopic screening for gastric cancer nationwide, the disparity of medical resources must first be resolved. © 2016 The Authors.

The aim of this paper is to share our experience and observations in running the Universal Neonatal Hearing Screening Program on a national level, present results and indicate some problems that have arisen during these 4 years. Polish Universal Neonatal Hearing Screening Program started back in 2002 in all neonatal units in Poland. Implemented testing methods consisted of test of transient evoked otoacoustic emission (TEOAE) performed in all new born children in their first 2-3 days of life and auditory brainstem response testing (ABR) conducted on children, who did not meet the TEOAE pass criteria. Additional questionnaire registered information on ototoxic drugs and family history of hearing impairment in every newborn. Diagnosed children were further referred for treatment and rehabilitation. After 4 years of running the program (between 2003 and 2006) a total number of 1,392,427 children were screened for hearing impairment, what stands for 96.3% of all delivered babies, registered in Poland. The screening program enabled to identify and refer for further treatment 2485 children with various types of hearing loss, 312 with profound (0.02% of population) and 145 with severe sensorineural hearing loss (0.11% of population). Our results indicate the accuracy of newborn hearing screening which remain an issue. Although improvement is needed in both intervention systems and diagnostic follow-up of hospitals, the Polish Universal Neonatal Hearing Program fully has achieved the main goal, the identification and treatment of hearing impaired children.

In most industrialized countries, screening programs for cervical cancer have shifted from cytology (Pap smear or ThinPrep) alone on clinician-obtained samples to the addition of screening for human papillomavirus (HPV), its main causative agent. For HPV testing, self-sampling instead of clinician-sampling has proven to be equally accurate, in particular for assays that use nucleic acid amplification techniques. In addition, HPV testing of self-collected samples in combination with a follow-up Pap smear in case of a positive result is more effective in detecting precancerous lesions than a Pap smear alone. Self-sampling for HPV testing has already been adopted by some countries, while others have started trials to evaluate its incorporation into national cervical cancer screening programs. Self-sampling may result in more individuals willing to participate in cervical cancer screening, because it removes many of the barriers that prevent women, especially those in low socioeconomic and minority populations, from participating in regular screening programs. Several studies have shown that the majority of women who have been underscreened but who tested HPV-positive in a self-obtained sample will visit a clinic for follow-up diagnosis and management. In addition, a self-collected sample can also be used for vaginal microbiome analysis, which can provide additional information about HPV infection persistence as well as vaginal health in general.

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 assesses consensus review of discordant screening mammography findings in terms of its sensitivity, safety, and effect on overall performance in the first 6 years of operation of the Irish National Breast Screening Program (NBSP). Women who participated in the Irish NBSP gave written informed consent for use of their data for auditing purposes. Local ethics committee approval was obtained. The study population consisted of women who participated in the Irish NBSP and underwent initial screening mammography at one of the two screening centers serving the eastern part of Ireland between 2000 and 2005. Independent double reading of mammograms was performed. When the readers disagreed regarding referral, the case was reviewed by a consensus panel. Of the 128 569 screenings performed, 1335 (1%) were discussed by consensus. Of the 1335 cases discussed by consensus, 606 (45.39%) were recalled for further assessment. This resulted in an overall recall rate of 4.41%. In those recalled to assessment, 71 cases of malignant disease were diagnosed (ductal carcinoma in situ, n = 24; invasive cancer, n = 47). The remaining 729 patients were returned to biennial screening. Of these 729 patients, seven had false-negative findings that were identified in the subsequent screening round. Use of the highest reader recall method, in which a patient is recalled if her findings are deemed abnormal by either reader, could potentially increase the cancer detection rate by 0.6 per 1000 women screened but would increase the recall rate by 12.69% and the number of false-positive findings by 15.37%. The consensus panel identified 71 (7.33%) of 968 cancers diagnosed. Consensus review substantially reduced the number of cases recalled and was associated with a low false-negative rate.

Background We estimated the number of women undergoing cervical cancer screening annually in Italy, the rates of cervical abnormalities detected, and the costs of screening and management of abnormalities. Methods The annual number of screened women was estimated from National Health Interview data. Data from the Italian Group for Cervical Cancer Screening were used to estimate the number of positive, negative and unsatisfactory Pap smears. The incidence of CIN (cervical intra-epithelial neoplasia) was estimated from the Emilia Romagna Cancer Registry. Patterns of follow-up and treatment costs were estimated using a typical disease management approach based on national guidelines and data from the Italian Group for Cervical Cancer Screening. Treatment unit costs were obtained from Italian National Health Service and Hospital Information System of the Lazio Region. Results An estimated 6.4 million women aged 25–69 years undergo screening annually in Italy (1.2 million and 5.2 million through organized and opportunistic screening programs, respectively). Approximately 2.4% of tests have positive findings. There are approximately 21,000 cases of CIN1 and 7,000–17,000 cases of CIN2/3. Estimated costs to the healthcare service amount to €158.5 million for screening and €22.9 million for the management of cervical abnormalities. Conclusion Although some cervical abnormalities might have been underestimated, the total annual cost of cervical cancer prevention in Italy is approximately €181.5 million, of which 87% is attributable to screening.

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.

United Nation's Sustainable Development Goals and the World Health Organization's Global Monitoring Framework support a strong global commitment to reducing the high burden of cervical and breast cancers among low- and middle-income countries. Strategies include vaccination, screening, and early diagnosis. Population-based surveys, such as those conducted by the Demographic and Health Surveys (DHS) Program, can collect the information needed to guide cancer control efforts in a standardized comparable manner. We identified and evaluated the breadth of breast and cervical cancer screening information that was collected by the DHS from 1984 through 2015. Then, we determined if these surveys currently provide the specific and measurable data about both the quantity and quality of cancer screening needed to guide national efforts to reduce the overall effects of cervical and breast cancers. We searched the DHS website to identify surveys conducted between the start of the DHS Program in 1984 and November 2015 that included questions about breast and cervical cancer screening. The relevant questions were extracted from the questionnaire, translated into English, and grouped by themes. Of the 90 countries where DHS surveys have been implemented, cervical cancer screening questions were included in 22 countries (24.4%) and breast cancer screening questions in 18 countries (20.0%). The common themes identified were disease knowledge, screening knowledge, screening practice, and screening outcomes. Most countries with survey questionnaires available for review addressed at least one aspect of screening practice (88.9% of cervical and 87.5% of breast), although few countries queried knowledge and outcomes. Questions that assess varied aspects of breast and cervical cancer screening have been incorporated into relatively few DHS surveys. The themes identified could guide the design of a standard set of questions for use in future population-based surveys and enable evaluation beyond the existence of screening, which would include assessment of the quality and impact of cervical and breast cancer screening.

Background Lung cancer screening programs may provide opportunities to reduce smoking rates among participants. This study evaluates the impact of lung cancer screening results on smoking cessation. Methods Data from Lung Screening Study participants in the National Lung Screening Trial (NLST; 2002–2009) were used to prepare multivariable longitudinal regression models predicting annual smoking cessation in those who were current smokers at study entry (n = 15489, excluding those developing lung cancer in follow-up). The associations of lung cancer screening results on smoking cessation over the trial period were analyzed. All hypothesis testing used two sided P values. Results In adjusted analyses, smoking cessation was strongly associated with the amount of abnormality observed in the previous year’s screening (P < .0001). Compared with those with a normal screen, individuals were less likely to be smokers if their previous year’s screen had a major abnormality that was not suspicious for lung cancer (odds ratio [OR] = 0.811; 95% confidence interval [CI] = 0.722 to 0.912; P < .001), was suspicious for lung cancer but stable from previous screens (OR = 0.785; 95% CI = 0.706 to 0.872; P < .001), or was suspicious for lung cancer and was new or changed from the previous screen (OR = 0.663; 95% CI = 0.607 to 0.724; P < .001). Differences in smoking prevalence were present up to 5 years after the last screen. Conclusions Smoking cessation is statistically significantly associated with screen-detected abnormality. Integration of effective smoking cessation programs within screening programs should lead to further reduction in smoking-related morbidity and mortality. PMID:24872540

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.

Why screening rates vary between Korea and Japan--differences between two national healthcare systems.

PubMed

Goto, Rei; Hamashima, Chisato; Mun, Sunghyun; Lee, Won-Chul

Both Japan and Korea provide population-based screening programs. However, screening rates are much higher in Korea than in Japan. To clarify the possible factors explaining the differences between these two countries, we analyzed the current status of the cancer screening and background healthcare systems. Population- based cancer screening in Korea is coordinated well with social health insurance under a unified insurer system. In Japan, there are over 3,000 insurers and coordinating a comprehensive strategy for cancer screening promotion has been very difficult. The public healthcare system also has influence over cancer screening. In Korea, public healthcare does not cover a wide range of services. Almost free cancer screening and subsidization for medical cost for cancers detected in population-screening provides high incentive to participation. In Japan, on the other hand, a larger coverage of medical services, low co-payment, and a lenient medical audit enables people to have cancer screening under public health insurance as well as the broad range of cancer screening. The implementation of evidence-based cancer screening programs may be largely dependent on the background healthcare system. It is important to understand the impacts of each healthcare system as a whole and to match the characteristics of a particular health system when designing an efficient cancer screening system.

Mental health screening and evaluation within prisons.

Current national standards and/or guidelines for correctional mental health care programs emphasize the importance of various levels of mental health screening and evaluation that should be performed by qualified personnel on all inmates as part of the admission process to a prison. The authors describe the results of a study that included data from all 50 state departments of corrections regarding prison mental health screening and evaluation models. The vast majority of states appear to have adopted some variation of the most recognized guidelines and/or standards (e.g., American Psychiatric Association, National Commission on Correctional Health Care, American Public Health Association) concerning correctional health care systems. Results are also provided concerning the use of standardized psychological tests and informed consent issues.

CMHC practices related to tardive dyskinesia screening and informed consent for neuroleptic drugs.

Benjamin, S; Munetz, M R

1994-04-01

The authors conducted a national survey of community mental health centers to determine their policies and practices about screening patients for tardive dyskinesia and obtaining informed consent for use of neuroleptic drugs. Clinical directors of 235 centers in the United States, selected by geographic region and population, were surveyed through a nine-item questionnaire. Although nearly all the 160 respondents reported that they screened patients for tardive dyskinesia, only about two-fifths had formal screening policies, and about two-fifths had screening programs. The Abnormal Involuntary Movement Scale examination was used by almost two-thirds of respondents who screened patients, and about one-fifth relied on unstructured observation. Slightly more than half of respondents specified a frequency for screening examinations, at a modal interval of six months. Seventy percent used nonpsychiatric clinicians for screening. Almost three-quarters of the respondents had informed consent policies for use of neuroleptics. Urban centers tended to be more aware than rural centers of the American Psychiatric Association's tardive dyskinesia screening guidelines. They also used fewer nonmedical practitioners for screening and were more likely to obtain informed consent for neuroleptics. Despite the existence of APA guidelines and state policies and regulations about tardive dyskinesia screening, a national effort to educate clinicians about prevention of tardive dyskinesia is still needed.

In 2001, the National Heart, Lung, and Blood Institute partnered with the National Council of La Raza to conduct a pilot test of its community-based outreach program Salud Para Su Corazón (Health for Your Heart), which aims to reduce the burden of morbidity and mortality associated with cardiovascular disease among Latinos. The effectiveness of promotores de salud (community health workers) in improving heart-healthy behaviors among Latino families participating in the pilot program at seven sites was evaluated. Data on the characteristics of the promotores in the Salud Para Su Corazón program were compiled. Promotores collected data on family risk factors, health habits, referrals and screenings, information sharing, and program satisfaction from 223 participating Latino families (320 individual family members) through questionnaires. Paired t tests and chi-square tests were used to measure pretest-posttest differences among program participants. Results demonstrated the effectiveness of the promotora model in improving heart-healthy behaviors, promoting community referrals and screenings, enhancing information sharing beyond families, and satisfying participants' expectations of the program. The main outcome of interest was the change in heart-healthy behaviors among families. The community outreach model worked well in the seven pilot programs because of the successes of the promotores and the support of the community-based organizations. Successes stemmed in part from the train-the-trainer approach. Promotoria, as implemented in this program, has the potential to be integrated with a medical model of patient care for primary, secondary, and tertiary prevention.

Study objective We describe the availability of preventive health services in US emergency departments (EDs), as well as ED directors’ preferred service and perceptions of barriers to offering preventive services. Methods Using the 2007 National Emergency Department Inventory (NEDI)–USA, we randomly sampled 350 (7%) of 4,874 EDs. We surveyed directors of these EDs to determine the availability of (1) screening and referral programs for alcohol, tobacco, geriatric falls, intimate partner violence, HIV, diabetes, and hypertension; (2) vaccination programs for influenza and pneumococcus; and (3) linkage programs to primary care and health insurance. ED directors were asked to select the service they would most like to implement and to rate 5 potential barriers to offering preventive services. Results Two hundred seventy-seven EDs (80%) responded across 46 states. Availability of services ranged from 66% for intimate partner violence screening to 19% for HIV screening. ED directors wanted to implement primary care linkage most (17%) and HIV screening least (2%). ED directors “agreed/strongly agreed” that the following are barriers to ED preventive care: cost (74%), increased patient length of stay (64%), lack of follow-up (60%), resource shifting leading to worse patient outcomes (53%), and philosophical opposition (27%). Conclusion Most US EDs offer preventive services, but availability and ED director preference for type of service vary greatly. The majority of EDs do not routinely offer Centers for Disease Control and Prevention–recommended HIV screening. Most ED directors are not philosophically opposed to offering preventive services but are concerned with added costs, effects on ED operations, and potential lack of follow-up. PMID:20889237

The Outcomes of an Educational Program Involving Men as Motivators to Encourage Women to Be Screened for Cervical Cancer.

Cervical cancer is a major health problem in South Africa. Despite having a national, population-based screening program, screening coverage is as low as 13%. Based on the role men could play in increasing cervical cancer screening and the low level of knowledge, men living in the study setting had about this health issue, we developed and pilot tested an educational program aimed at empowering men to teach their female partners and family members about cervical cancer and motivate them to be screened. The study setting was Ward 23 in Muldersdrift, a semi-urban, resource poor area situated northeast of Johannesburg. We used an intervention research design to assess the outcomes of our educational program. The primary outcome was screening uptake, with knowledge the secondary outcome. Statistics and face-to-face and telephone interviews, guided by questionnaires, were used to collect the data which were analyzed by means of descriptive statistics and content analysis. A total of 120 men (n = 120) participated in the educational program and 100 (n = 100) completed the post-test questionnaire. Only 30 women (n = 30) reported for screening. The men's knowledge improved after the education program but did not guarantee that they would educate women about cervical cancer as only 55% (n = 66) indicated they taught a female family member or their partner. Cultural restrictions were the most common reason presented for not teaching women about this health issue. Ways of supporting men to overcome cultural barriers prohibiting them from discussing matters related to sexuality should be explored, before refining and replicating the intervention.

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.

To develop recommendations for practising physicians on the advisability of screening for human papillomavirus (HPV) infection in asymptomatic women. Visual inspection, Papanicolaou testing, colposcopy or cervicography, use of HPV group-specific antigen, DNA hybridization, dot blot technique, Southern blot technique or polymerase chain reaction followed by physical or chemical therapeutic intervention. Evidence for a link between HPV infection and cervical cancer, sensitivity and specificity of HPV screening techniques, effectiveness of treatments for HPV infection, and the social and economic costs incurred by screening. MEDLINE was searched for articles published between January 1966 to June 1993 with the use of the key words "papillomavirus," "cervix neoplasms," "mass screening," "prospective studies," "prevalence," "sensitivity," "specificity," "human" and "female." Proven cost-effective screening techniques that could lead to decreased morbidity or mortality were given a high value. The evidence-based methods and values of the Canadian Task Force on the Periodic Health Examination were used. Potential benefits are to prevent cervical cancer and eliminate HPV infection. Potential harmful effects include the creation of an unnecessary burden on the health care system and the labelling of otherwise healthy people as patients with a sexually transmitted disease for which therapy is generally ineffective. Potential costs would include expense of testing, increased use of colposcopy and treatment. There is fair evidence to exclude HPV screening (beyond Papanicolaou testing for cervical cancer) in asymptomatic women (grade D recommendation). The report was reviewed by members of the task force and three external reviewers who were selected to represent different areas of expertise. These guidelines were developed and endorsed by the task force, which is funded by Health Canada and the National Health Research and Development Program. The principal author (K.J.) was supported in part by the National Health Research and Development Program through a National Health Fellowship (AIDS).

Population-based programs for increasing colorectal cancer screening in the United States.

Answer questions and earn CME/CNE Screening to detect polyps or cancer at an early stage has been shown to produce better outcomes in colorectal cancer (CRC). Programs with a population-based approach can reach a large majority of the eligible population and can offer cost-effective interventions with the potential benefit of maximizing early cancer detection and prevention using a complete follow-up plan. The purpose of this review was to summarize the key features of population-based programs to increase CRC screening in the United States. A search was conducted in the SCOPUS, OvidSP, and PubMed databases. The authors selected published reports of population-based programs that met at least 5 of the 6 International Agency for Research on Cancer (IARC) criteria for cancer prevention and were known to the National Colorectal Cancer Roundtable. Interventions at the level of individual practices were not included in this review. IARC cancer prevention criteria served as a framework to assess the effective processes and elements of a population-based program. Eight programs were included in this review. Half of the programs met all IARC criteria, and all programs led to improvements in screening rates. The rate of colonoscopy after a positive stool test was heterogeneous among programs. Different population-based strategies were used to promote these screening programs, including system-based, provider-based, patient-based, and media-based strategies. Treatment of identified cancer cases was not included explicitly in 4 programs but was offered through routine medical care. Evidence-based methods for promoting CRC screening at a population level can guide the development of future approaches in health care prevention. The key elements of a successful population-based approach include adherence to the 6 IARC criteria and 4 additional elements (an identified external funding source, a structured policy for positive fecal occult blood test results and confirmed cancer cases, outreach activities for recruitment and patient education, and an established rescreening process). © 2015 American Cancer Society.

[Neurodevelopmental assessment of patients with congenital hypothyroidism].

PubMed

Núñez, Alicia; Bedregal, Paula; Becerra, Carlos; Grob L, Francisca

2017-12-01

Congenital hypothyroidism (CH) is the most common cause of preventable cognitive disability worldwide. Generally, it is produced by an alteration in the embryogenesis of the thyroid gland or by an alteration in the synthesis of thyroid hormones, which determine that affected patients have low or absent thyroid hormone concentrations. The importance of this fact is that brain development during the first three years of life is highly dependent on thyroid hormones. Prior to the implementation of national neonatal screening programs around the world, 8 to 27% of children with CH had an IQ lower than 70. Nowadays, this percentage is close to 0 in countries that have implemented the program. In Chile, CH neonatal screening program achieved national coverage in 1996. Currently, the incidence of the disease in our country is 1: 3163. The degree of disability produced by CH not only depends on the time of detection of the disease and the prompt start of therapy, but also on an adequate monitoring. Despite screening programs, neurocognitive impairment in schoolchildren and teenagers with CH is still observed, reflected in lower scores in cognitive, language and gross motor assessments, receptive communication, expressive communication, fine motor and gross motor skills compared to healthy children. Also, lesser achievements in learning and language disorders are observed. The objective of this review is to update the information available on neurodevelopment of patients with CH.

To assess cancers diagnosed and the stage of cancer at the time of diagnosis among low-income, under-insured, or uninsured women who received services through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). Using the NBCCEDP database, we examined the number and percent of women diagnosed during 2009-2011 with in situ breast cancer, invasive breast cancer, and invasive cervical cancer by demographic and clinical characteristics, including age, race and ethnicity, test indication (screening or diagnostic), symptoms (for breast cancer), and screening history (for cervical cancer). We examined these characteristics by stage at diagnosis, a new variable included in the database obtained by linking with state-based central cancer registries. There were 11,569 women diagnosed with invasive breast cancer, 1,988 with in situ breast cancer, and 583 with invasive cervical cancer through the NBCCEDP. Women who reported breast symptoms or who had diagnostic mammography were more likely to be diagnosed with breast cancer, and at a later stage, than those who did not have symptoms or who had screening mammography. Women who had been rarely or never screened for cervical cancer were more likely to be diagnosed with cervical cancer, and at a later stage, than women who received regular screenings. Women served through the NBCCEDP who have not had prior screening or who have symptoms were more often diagnosed with late-stage disease.

To determine whether diabetic retinal screening services and retinopathy referral centres in New Zealand meet the national guidelines for referral and assessment of screen detected moderate retinal and mild macular diabetic eye disease. Diabetic retinal screening pathways and the data collected at four main centre retinal screening services were described and compared with recommendations in the national diabetes retinal screening guidelines. A retrospective audit of photoscreen detected moderate retinopathy (grade R3), and mild maculopathy (grades M2B and M3) during May to August 2008 was undertaken. Data collected by retinopathy referral centres were used to examine the follow-up of screen detected cases and to make comparisons with the national recommendations. All four screening services used the guidelines for grading, but the recommended dataset was incomplete. Not all recorded data were readily accessible. The retinal photos of 157 (2.4%) patients were graded as R3, M2B, M3 or a combination. The proportion of those screened with these grades varied across the four centres from 1.2% to 3.4%. Follow-up of the 157 screen positive patients did not always comply with guideline recommendations. Seventy five (48%) were referred for review by an ophthalmologist as recommended, 45 (60% of referred) were seen within the recommended six months. Nine patients (15% of the 60 with a documented assessment) were referred for or received laser treatment at 12-months follow-up. Quality diabetic retinal screening data systems and quality assurance programs are required to improve the monitoring and quality of retinal screening in New Zealand. © 2012 The Authors.

Background In 2001 Brazilian citizens aged 40 or older were invited to participate in a nationwide population screening program for diabetes. Capillary glucose screening tests and procedures for diagnostic confirmation were offered through the national healthcare system, diagnostic priority being given according to the severity of screening results. The objective of this study is to evaluate the initial impact of the program. Methods Positive testing was defined by a fasting capillary glucose ≥ 100 mg/dL or casual glucose ≥ 140 mg/dL. All test results were tabulated locally and aggregate data by gender and clinical categories were sent to the Ministry of Health. To analyze individual characteristics of screening tests performed, a stratified random sample of 90,106 tests was drawn. To describe the actions taken for positive screenees, a random sub-sample of 4,906 positive screenees was actively followed up through home interviews. Main outcome measures considered were the number of diabetes cases diagnosed and cost per case detected and incorporated into healthcare. Results Of 22,069,905 screening tests performed, we estimate that 3,417,106 (95% CI 3.1 – 3.7 million) were positive and that 346,168 (290,454 – 401,852) new cases were diagnosed (10.1% of positives), 319,157 (92.2%) of these being incorporated into healthcare. The number of screening tests needed to detect one case of diabetes was 64. As many cases of untreated but previously known diabetes were also linked to healthcare providers during the Campaign, the estimated number needed screen to incorporate one case into the healthcare system was 58. Total screening and diagnostic costs were US$ 26.19 million, the cost per diabetes case diagnosed being US$ 76. Results were especially sensitive to proportion of individuals returning for diagnostic confirmation. Conclusion This nationwide population-based screening program, conducted through primary healthcare services, demonstrates the feasibility, within the context of an organized national healthcare system, of screening campaigns for chronic diseases. Although overall costs were significant, cost per new case diagnosed was lower than previously reported. However, cost-effectiveness analysis based on more clinically significant outcomes needs to be conducted before this screening approach can be recommended in other settings. PMID:18808662

Cervical cancer risk levels in Turkey and compliance to the national cervical cancer screening standard.

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.

Medical screening requires always assessment. On the basis of ongoing studies on occupational health asbestos programs, we suggest some recommendations for asbestos screening after occupational exposure. The proposal for asbestos workers post-exposure surveillance should take into account the medical but also the social aspects of the problem. Post-exposure screening of asbestos workers includes an evaluation of occupational exposure, compulsory basis medical check-up, the characteristics of the radiological investigations and schedule of the medical surveillance. In conclusion, we suggest some general recommendations for asbestos screening after occupational exposure, particularly the necessity to obtain a concerted approach of asbestos screening with regional and national networks, the concern of their assessment and the implementation of specific research studies.

Although Spain is the European country with the highest Chagas disease burden, the country does not have a national control program of the disease. The purpose of this study is to evaluate the efficiency of several strategies for Chagas disease screening among Latin American residents living in Spain. The following screening strategies were evaluated: (1) non-screening; (2) screening of the Latin American pregnant women and their newborns; (3) screening also the relatives of the positive pregnant women; (4) screening also the relatives of the negative pregnant women. A cost-utility analysis was carried out to compare the four strategies from two perspectives, the societal and the Spanish National Health System (SNHS). A decision tree representing the clinical evolution of Chagas disease throughout patient's life was built. The strategies were compared through the incremental cost-utility ratio, using euros as cost measurement and quality-adjusted life years as utility measurement. A sensitivity analysis was performed to test the model parameters and their influence on the results. We found the "Non-screening" as the most expensive and less effective of the evaluated strategies, from both the societal and the SNHS perspectives. Among the screening evaluated strategies the most efficient was, from both perspectives, to extent the antenatal screening of the Latin American pregnant women and their newborns up to the relatives of the positive women. Several parameters influenced significantly on the sensitivity analyses, particularly the chronic treatment efficacy or the prevalence of Chagas disease. In conclusion, for the general Latin American immigrants living in Spain the most efficient would be to screen the Latin American mothers, their newborns and the close relatives of the mothers with a positive serology. However for higher prevalence immigrant population the most efficient intervention would be to extend the program to the close relatives of the negative mothers. Copyright © 2015 Elsevier B.V.

To evaluate the cost-effectiveness for a screening interval longer than 1 year detecting diabetic retinopathy (DR) through the estimation of incremental costs per quality-adjusted life year (QALY) based on the best available clinical data in Japan. A Markov model with a probabilistic cohort analysis was framed to calculate incremental costs per QALY gained by implementing a screening program detecting DR in Japan. A 1-year cycle length and population size of 50,000 with a 50-year time horizon (age 40-90 years) was used. Best available clinical data from publications and national surveillance data was used, and a model was designed including current diagnosis and management of DR with corresponding visual outcomes. One-way and probabilistic sensitivity analyses were performed considering uncertainties in the parameters. In the base-case analysis, the strategy with a screening program resulted in an incremental cost of 5,147 Japanese yen (¥; US$64.6) and incremental effectiveness of 0.0054 QALYs per person screened. The incremental cost-effectiveness ratio was ¥944,981 (US$11,857) per QALY. The simulation suggested that screening would result in a significant reduction in blindness in people aged 40 years or over (-16%). Sensitivity analyses suggested that in order to achieve both reductions in blindness and cost-effectiveness in Japan, the screening program should screen those aged 53-84 years, at intervals of 3 years or less. An eye screening program in Japan would be cost-effective in detecting DR and preventing blindness from DR, even allowing for the uncertainties in estimates of costs, utility, and current management of DR.

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

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.

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.

American Medical Society for Sports Medicine college team physicians. Screening practices survey administered to college team physicians. Cardiovascular preparticipation screening practices including noninvasive cardiac screening (NICS) such as electrocardiogram (ECG) or echocardiogram. Two hundred twenty-four of 613 AMSSM members identifying themselves as college team physicians (36.5%) responded: National Collegiate Athletic Association Division I: 146, Division II: 41, Division III: 27, National Association of Intercollegiate Athletics: 8, and Junior College: 2. The majority (78%) of schools conducted the American Heart Association (AHA) 12-element history and physical examination. Division I institutions were more likely to add an ECG and/or echocardiogram (30%) to their preparticipation examination (PPE) compared with lower divisions (P < 0.0001). Those Division I schools using NICS were more likely to do so for all athletes (P < 0.001) or revenue generating sports (P < 0.001), whereas other institutions did so only for high-risk subgroups (P < 0.01). Lower division schools would consider adding ECG if it cost less (P = 0.01) or if there were more local expertise in athlete-specific interpretation standards (P = 0.04). Many National Collegiate Athletic Association Athletes Division I programs already use NICS to screen athletes, whereas a significant portion of lower division schools add ECG for athletes deemed high risk. Increased use of these modalities suggests limitations of traditional PPE screening methods. This is the first study to assess cardiac screening practices across all collegiate divisions and broadens our understanding of cardiac screening in high-level athletes.

The Korean National Cancer Screening Survey (KNCSS), a nationwide cross-sectional survey, has been conducted annually since 2004. The current study was conducted to report on the trends in screening rates among Korean men and women, and to evaluate policies regarding cancer screening programs implemented to reduce the burden of cancer. The current study used KNCSS data. The eligible study population included men aged 40-74 years and women aged 30-74 years with no cancer history. The lifetime screening rate, screening rate with recommendation, and changes in annual rates were calculated for five major cancers (i.e., stomach, liver, colorectal, breast, and cervix uteri). The screening rates with recommendation increased by 4.2% (95% confidence interval [CI], 3.7% to 4.8%) annually for stomach cancer, 1.2% (95% CI, 0.1% to 2.4%) for liver cancer, 3.0% (95% CI, 1.8% to 4.1%) for colorectal cancer, 3.7% (95% CI, 2.7% to 4.8%) for breast cancer, and 1.3% (95% CI, 0.8% to 1.8%) for cervical cancer. In 2013, the screening rates with recommendation for stomach, liver, colorectal, breast, and cervical cancers were 73.6%, 33.6%, 55.6%, 59.7%, and 67.0%, respectively. Both the lifetime screening rates and screening rates with recommendation for the five above-mentioned cancers increased annually from 2004 to 2013.

There is little research at the national level on access to employee wellness programs and the use of preventive care services. This study examined the use of seven preventive care services among U.S working adults with access to employee wellness programs. The study population comprised 17,699 working adults aged ≥18 years, obtained from the 2015 National Health Interview Survey. Multivariate logistic regression models examined the relationship between access to employee wellness programs and use of seven preventive care services: influenza vaccination, blood pressure check, diabetes check, cholesterol check, Pap smear test, mammogram, and colon cancer screening. Data analysis began in Fall 2016. Overall, 46.6% of working adults reported having access to employee wellness programs in 2015. Working adults with access to employee wellness programs had higher odds of receiving influenza vaccination (OR=1.57, 95% CI=1.43, 1.72, p<0.001), blood pressure check (OR=2.46, 95% CI=2.17, 2.78, p<0.001), diabetes check (OR=1.30, 95% CI=1.12, 1.50, p<0.001), cholesterol check (OR=1.48, 95% CI=1.33, 1.67, p<0.001), and mammogram (OR=1.57, 95% CI=1.24, 1.98, p<0.001). However, there was no significant difference between access to employee wellness programs and the use of Pap smear test and colon cancer screening services. Using a nationally representative sample of individuals, this study found a positive association between access to employee wellness programs and the use of preventive care services. The results support favorable policies to encourage implementing wellness programs in all worksites, especially those with <50 employees. Copyright © 2017 American Journal of Preventive Medicine.

Newborn screening (NBS) identifies infants with rare conditions to prevent death or the onset of irreversible morbidities. Conditions on the Health and Human Services Secretary's Recommended Uniform Screening Panel have been adopted by most state NBS programs, providing a consistent approach for identification of affected newborns across the United States. Screen-positive newborns are identified and referred for confirmatory diagnosis and follow-up. The designation of a clinically significant phenotype precursor to a clinical diagnosis may vary between clinical specialists, resulting in diagnostic variation. Determination of disease burden and birth prevalence of the screened conditions by public health tracking is made challenging by these variations. This report describes the development of a core group of new case definitions, along with implications, plans for their use, and links to the definitions that were developed by panels of clinical experts. These definitions have been developed through an iterative process and are piloted in NBS programs. Consensus public health surveillance case definitions for newborn screened disorders will allow for consistent categorization and tracking of short- and long-term follow-up of identified newborns at the local, regional, and national levels.

Mortality and morbidity rates of cervical, breast, and colorectal cancers (CRC) can be decreased via effective screening strategies. Developing countries are to be expected to establish and implement their own programs. To evaluate regional awareness and status of cervical, breast, and CRC screening, a questionnaire-based study was conducted in 500 volunteers from a Turkish community hospital. Awareness rates were 57.4% for Pap smear, 61.2% for mammography, and 25.4% for CRC. Implementation rates were 19.2%, 23.9%, and 12%, respectively. Positive family history for gynecologic cancer and past cervical ablative procedure parameters were related to higher Pap smear rates. Educational level, breast self-exam, and positive Pap smear history parameters were related to higher mammography rates. Factors related to higher colorectal cancer screening rates were nulliparity and positive Pap smear history. Cancer screening rates for this Turkish city are still below the expected levels despite recently revitalized national screening program. For success, it is essential not only to educate rural populations but also to train negligent healthcare providers regularly.

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

Norway introduced newborn screening for cystic fibrosis (CF) March 1, 2012. We present results from the first three years of the national newborn CF screening program. Positive primary screening of immunoreactive trypsinogen (IRT) was followed by DNA testing of the Cystic fibrosis transmembrane conductance regulator (CFTR) gene. Infants with two CFTR mutations were reported for diagnostic follow-up. Of 181,859 infants tested, 1454 samples (0.80%) were assessed for CFTR mutations. Forty children (1:4546) had two CFTR mutations, of which only 21 (1:8660) were confirmed to have a CF diagnosis. The CFTR mutations differed from previously clinically diagnosed CF patients, and p.R117H outnumbered p.F508del as the most frequent mutation. One child with a negative IRT screening test was later clinically diagnosed with CF. The CF screening program identified fewer children with a conclusive CF diagnosis than expected. Our data suggest a revision of the IRT/DNA protocol. Copyright © 2016 European Cystic Fibrosis Society. Published by Elsevier B.V. All rights reserved.

AIM: To assess the cost-effectiveness of two population-based hepatocellular carcinoma (HCC) screening programs, two-stage biomarker-ultrasound method and mass screening using abdominal ultrasonography (AUS). METHODS: In this study, we applied a Markov decision model with a societal perspective and a lifetime horizon for the general population-based cohorts in an area with high HCC incidence, such as Taiwan. The accuracy of biomarkers and ultrasonography was estimated from published meta-analyses. The costs of surveillance, diagnosis, and treatment were based on a combination of published literature, Medicare payments, and medical expenditure at the National Taiwan University Hospital. The main outcome measure was cost per life-year gained with a 3% annual discount rate. RESULTS: The results show that the mass screening using AUS was associated with an incremental cost-effectiveness ratio of USD39825 per life-year gained, whereas two-stage screening was associated with an incremental cost-effectiveness ratio of USD49733 per life-year gained, as compared with no screening. Screening programs with an initial screening age of 50 years old and biennial screening interval were the most cost-effective. These findings were sensitive to the costs of screening tools and the specificity of biomarker screening. CONCLUSION: Mass screening using AUS is more cost effective than two-stage biomarker-ultrasound screening. The most optimal strategy is an initial screening age at 50 years old with a 2-year inter-screening interval. PMID:27022228

The National Institutes of Health have made substantial investments in genomic studies and technologies to identify DNA sequence variants associated with human disease phenotypes. The National Heart, Lung, and Blood Institute has been at the forefront of these commitments to ascertain genetic variation associated with heart, lung, blood, and sleep diseases and related clinical traits. Genome-wide association studies, exome- and genome-sequencing studies, and exome-genotyping studies of the National Heart, Lung, and Blood Institute-funded epidemiological and clinical case-control studies are identifying large numbers of genetic variants associated with heart, lung, blood, and sleep phenotypes. However, investigators face challenges in identification of genomic variants that are functionally disruptive among the myriad of computationally implicated variants. Studies to define mechanisms of genetic disruption encoded by computationally identified genomic variants require reproducible, adaptable, and inexpensive methods to screen candidate variant and gene function. High-throughput strategies will permit a tiered variant discovery and genetic mechanism approach that begins with rapid functional screening of a large number of computationally implicated variants and genes for discovery of those that merit mechanistic investigation. As such, improved variant-to-gene and gene-to-function screens-and adequate support for such studies-are critical to accelerating the translation of genomic findings. In this White Paper, we outline the variety of novel technologies, assays, and model systems that are making such screens faster, cheaper, and more accurate, referencing published work and ongoing work supported by the National Heart, Lung, and Blood Institute's R21/R33 Functional Assays to Screen Genomic Hits program. We discuss priorities that can accelerate the impressive but incomplete progress represented by big data genomic research. © 2018 American Heart Association, Inc.

Colorectal cancer is a major cause of morbidity and mortality throughout the world. Colorectal cancer screening is an optimal way for reducing of morbidity and mortality and a clinical decision support system (CDSS) plays an important role in predicting success of screening processes. DSS is a computer-based information system that improves the delivery of preventive care services. The aim of this article was to detail engineering of information requirements and work flow design of CDSS for a colorectal cancer screening program. In the first stage a screening minimum data set was determined. Developed and developing countries were analyzed for identifying this data set. Then information deficiencies and gaps were determined by check list. The second stage was a qualitative survey with a semi-structured interview as the study tool. A total of 15 users and stakeholders' perspectives about workflow of CDSS were studied. Finally workflow of DSS of control program was designed by standard clinical practice guidelines and perspectives. Screening minimum data set of national colorectal cancer screening program was defined in five sections, including colonoscopy data set, surgery, pathology, genetics and pedigree data set. Deficiencies and information gaps were analyzed. Then we designed a work process standard of screening. Finally workflow of DSS and entry stage were determined. A CDSS facilitates complex decision making for screening and has key roles in designing optimal interactions between colonoscopy, pathology and laboratory departments. Also workflow analysis is useful to identify data reconciliation strategies to address documentation gaps. Following recommendations of CDSS should improve quality of colorectal cancer screening.

Screening programs to detect visual abnormalities in children vary among countries. The aim of this study is to describe experts' perception of best practice guidelines and competency framework for visual screening in children. A qualitative focus group technique was applied during the Portuguese national orthoptic congress to obtain the perception of an expert panel of 5 orthoptists and 2 ophthalmologists with experience in visual screening for children (mean age 53.43 years, SD ± 9.40). The panel received in advance a script with the description of three tuning competencies dimensions (instrumental, systemic, and interpersonal) for visual screening. The session was recorded in video and audio. Qualitative data were analyzed using a categorical technique. According to experts' views, six tests (35.29%) have to be included in a visual screening: distance visual acuity test, cover test, bi-prism or 4/6(Δ) prism, fusion, ocular movements, and refraction. Screening should be performed according to the child age before and after 3 years of age (17.65%). The expert panel highlighted the influence of the professional experience in the application of a screening protocol (23.53%). They also showed concern about the false negatives control (23.53%). Instrumental competencies were the most cited (54.09%), followed by interpersonal (29.51%) and systemic (16.4%). Orthoptists should have professional experience before starting to apply a screening protocol. False negative results are a concern that has to be more thoroughly investigated. The proposed framework focuses on core competencies highlighted by the expert panel. Competencies programs could be important do develop better screening programs.

The Breast Health Surveys, conducted by the National Breast Cancer Centre (NBCC) in 1996 and 2003, are designed to gain insight into the knowledge, attitudes and behaviours of a nationally representative sample of Australian women on issues relevant to breast cancer. In this article, we focus on major aspects of the design and present results on respondents' knowledge about mammographic screening. The 2003 BHS surveyed English-speaking Australian women aged 30-69 without a history of breast cancer using computer-assisted telephone interviewing. Questions covered the following themes: knowledge and perceptions about incidence, mortality and risk; knowledge and behaviour regarding early detection, symptoms and diagnosis; mammographic screening; treatment; and accessibility and availability of information and services. Respondents were selected using a complex sample design involving stratification. Sample weights against Australian population benchmarks were used in all statistical analyses. Means and proportions for the entire population and by age group and area of residence were calculated. Statistical tests were conducted using a level of significance of 0.01. Of the 3,144 respondents who consented to being interviewed, 138 (4.4%) had a previous diagnosis of breast cancer and were excluded leaving 3,006 completed interviews eligible for analysis. A majority of respondents (61.1%) reported ever having had a mammogram and 29.1% identified mammography as being the best way of finding breast cancer. A majority of women (85.9%) had heard of the BreastScreen Australia (BSA) program, the national mammographic screening program providing free biennial screening mammograms, with 94.5% believing that BSA attendance was available regardless of the presence or absence of symptoms. There have been substantial gains in women's knowledge about mammographic screening over the seven years between the two surveys. The NBCC Breast Health Surveys provide a valuable picture of the knowledge of Australian women about a range of issues. The present analysis shows significant gains in knowledge and behaviours relating to mammographic screening, while identifying additional areas for targeted improvement, as in the need to better communicate with women about screening and diagnostic services. Further analysis of additional core topic areas (eg., incidence, mortality, risk and treatment) will provide equally noteworthy insight.

[The strategy for establishment of comprehensive cervical cancer prevention and control in the world].

Cervical cancer is one of the most common malignancies among women. Screening programs for cervical cancer have been implemented in many developed countries. Comprehensive systems for cervical cancer prevention and control have improved over the past 30 years, which has led to a significant decline in the morbidity and mortality of cervical cancer. Since 2009, the Chinese government has conducted the Cervical Cancer and Breast Cancer Screening Program for Rural Women on a national scale, which has substantially improved cervical cancer prevention and control. However, a comprehensive system for cervical cancer prevention has been not established in China. It is essential to investigate suitable strategies for cervical cancer prevention system in the country by referring to the experiences of developed nations in comparison with the situation in China, with respect to system operations, compatibility with the existing health care system, choice of suitable technologies, and information and evaluation platforms.

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.

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.

Estimating the costs of cervical cancer screening in high-burden Sub-Saharan African countries.

To estimate the capital investment and recurrent costs of national cervical cancer screening and precancer treatment programs in 23 high-incidence countries in Sub-Saharan Africa in order to provide estimates of the investment required to tackle the burden of cervical cancer in this region. These 23 countries account for 64% of the annual cervical cancer deaths in this region. Secondary data were used to estimate the financial costs of equipment purchases and economic costs of screening and treating eligible women over a 10-year period. Screening would be by visual inspection with acetic acid and treatment by cryotherapy or loop electrosurgical excision procedure. Approximately US $59 million would be required to purchase treatment equipment if cryotherapy were placed at every screening facility. Approximately 20 million women would be screened over 10 years. Cost per woman screened in a screen-and-treat program was either US $3.33 or US $7.31, and cost per woman treated was either US $38 or US $71 depending on the location of cryotherapy equipment. It would take less than US $10 per woman screened to significantly decrease the cervical cancer deaths that will occur in Sub-Saharan Africa over the next 10 years.

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.

Objective. To assess willingness to participate and diagnostic accuracy of visual inspection for early detection of cervical neoplasia among women in a health insurance company. Patients and Method. Cervical cancer screening was systematically proposed to 800 women after consecutive information and awareness sessions. The screening method was visual inspection with acetic acid (VIA) or Lugol's iodine (VILI). Results. Among the 800 identified women, 640 (82%) have accepted the screening, their mean age was 39 years, and 12.0% of them were involved in a polygamist couple. 28.2% of women had prior cervical screening. VIA has been detected positive in 5.9% of women versus 8.6% for VILI. The sensitivity was 72.9% and specificity was 95.2% for VIA versus 71.2% and 97.3% for VILI respectively. The histological examination highlighted a nonspecific chronic cervicitis in 4.6%, CIN1 lesions in 5.91%, and CIN2/3 in 1.2% of the cases. Conclusion. Cervical cancer screening by visual inspection showed appropriate diagnostic accuracy when used to detect early cervical lesions. It is a simple and easy to perform method that could be introduced progressively in the health insurance policy while waiting for a national screening program.

The screening program guidelines specify that the call back rate of women for additional imaging (positive mammogram) should not exceed 7% at initial screening, and 5% at subsequent screening. Materials and methods. Results in the Isere region (12%) have prompted a review of the correlation between the call back rate and indicators of quality (detection rate, sensitivity, specificity, positive predictive value) for the radiologists providing interpretations during that time period. Three groups of radiologists were identified: the group with call back rate of 10% achieved the best results (sensitivity: 92%, detection rate: 0.53%, specificity: 90%). The group with lowest call back rate (7.7%) showed insufficient sensitivity (58%). The last group with call back rate of 18.3%, showed no improvement in sensitivity (82%) and detection rate (0.53%), but showed reduced specificity (82%). The protocol update in 2001 does not resolve this problematic situation and national results continue to demonstrate a high percentage of positive screening mammograms. A significant increase in the number of positive screening examinations compared to recommended guidelines is not advantageous and leads to an overall decrease in the quality of the screening.

Background New Zealand (NZ) is considering transitioning from 3-yearly cervical cytology screening in women 20–69 years (current practice) to primary HPV screening. We evaluated HPV-based screening in both HPV-unvaccinated women and cohorts offered HPV vaccination in New Zealand (vaccination coverage ~50%). Methods A complex model of HPV transmission, vaccination, cervical screening, and invasive cervical cancer was extensively validated against national population-based datasets. Sixteen potential strategies for HPV screening were considered. Results Most primary HPV strategies were more effective than current practice, for both unvaccinated women and cohorts offered vaccination. The optimal strategy for both groups was 5-yearly HPV screening in women aged 25–69 years with partial genotyping for HPV 16/18 and referral to colposcopy, and cytological triage of other oncogenic types. This is predicted to reduce cervical cancer incidence and mortality by a further 12–16% and to save 4–13% annually in program costs (excluding overheads). The findings are sensitive to assumptions about future adherence to initiating screening at 25 years. Conclusion Primary HPV screening with partial genotyping would be more effective and less costly than the current cytology-based screening program, in both unvaccinated women and cohorts offered vaccination. These findings have been considered in a review of cervical screening in NZ. PMID:27187495

To assess the national inequality of school readiness and autism among 6-year-old Iranian children before school entry using a national health assessment survey. In a cross-sectional nationwide survey, all Iranian children entering public and private elementary schools were asked to participate in a mandatory national screening program in Iran in 2009 in two levels of screening and diagnostic levels. The study population consisted of 955388 children (48.5% girls and 76.1% urban residents). Of the whole children, 3.1% of the 6-year-old children had impaired vision. In addition, 1.2, 1.8, 1.4, 7.6, 0.08, 10, 10.9, 56.7, 0.7, 0.8 and 0.6 percent had color blindness, hearing impaired, speech disorder, school readiness, autism, height to age retardation, body mass index extremes, decayed teeth, disease with special needs, spinal disorders, and hypertension, respectively. The distribution of these disorders was unequally distributed across provinces. Our results confirmed that there is an inequality in distribution of school readiness and autism in 6-year-old children across Iranian provinces. The observed burden of these distributions among young children needs a comprehensive national policy with evidence-based province programs to identify the reason for different inequality among provinces.

March is national colorectal cancer awareness month. It is estimated that as many as 60% of colorectal cancer deaths could be prevented if all men and women aged 50 years or older were screened routinely. In 2000, Katie Couric's televised colonoscopy led to a 20% increase in screening colonoscopies across America, a stunning rise called the "Katie Couric Effect". This event demonstrated how celebrity endorsement affects health behavior. Currently, discussion is ongoing about the optimal strategy for CRC screening, particularly the costs of screening colonoscopy. The current CRC screening guidelines are summarized in Table 2. Debates over the optimum CRC screening test continue in the face of evidence that 22 million Americans aged 50 to 75 years are not screened for CRC by any modality and 25,000 of those lives may have been saved if they had been screened for CRC. It is clear that improving screening rates and reducing disparities in underscreened communities and population subgroups could further reduce colorectal cancer morbidity and mortality. National Institutes of Health consensus identified the following priority areas to enhance the use and quality of colorectal cancer screening: Eliminate financial barriers to colorectal cancer screening and appropriate follow-up of positive results of colorectal cancer screening. Develop systems to ensure the high quality of colorectal cancer screening programs. Conduct studies to determine the comparative effectiveness of the various colorectal cancer screening methods in usual practice settings. Encouraging population adherence to screening tests and allowing patients to select the tests they prefer may do more good (as long as they choose something) than whatever procedure is chosen by the medical profession as the preferred test.

To determine whether the addition of hepatitis B virus (HBV) vaccine to national immunization programs improved vaccination rates among refugee children, a marginalized population with limited access to care. The sample included 2291 refugees younger than 19 years who completed HBV screening after arrival in the United States. Children were categorized by having been born before or after the addition of the 3-dose HBV vaccine to their birth country's national immunization program. The outcome was serological evidence of immunization. The odds of serological evidence of HBV immunization were higher for children born after the addition of HBV vaccine to their birth country's national immunization program (adjusted odds ratio = 2.54; 95% confidence interval = 2.04, 3.15). National HBV vaccination programs have contributed to the increase in HBV vaccination coverage observed among US-bound refugee children. Ongoing public health surveillance is needed to ensure that vaccine rates are sustained among diverse, conflict-affected, displaced populations.

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

EPA Pesticide Factsheets

The National Research Council of the United States National Academies of Science has recently released a document outlining a long-range vision and strategy for transforming toxicity testing from largely whole animal-based testing to one based on in vitro assays. “Toxicity Testing in the 21st Century: A Vision and a Strategy” advises a focus on relevant human toxicity pathway assays. Toxicity pathways are defined in the document as “Cellular response pathways that, when sufficiently perturbed, are expected to result in adverse health effects”. Results of such pathway screens would serve as a filter to drive selection of more specific, targeted testing that will complement and validate the pathway assays. In response to this report, the US EPA has partnered with two NIH organizations, the National Toxicology Program and the NIH Chemical Genomics Center (NCGC), in a program named Tox21. A major goal of this collaboration is to screen chemical libraries consisting of known toxicants, chemicals of environmental and occupational exposure concern, and human pharmaceuticals in cell-based pathway assays. Currently, approximately 3000 compounds (increasing to 9000 by the end of 2009) are being validated and screened in quantitative high-throughput (qHTS) format at the NCGC producing extensive concentration-response data for a diverse set of potential toxicity pathways. The Tox21 collaboration is extremely interested in accessing additional toxicity pathway assa

Computational toxicology is the application of mathematical and computer models to help assess chemical hazards and risks to human health and the environment. Supported by advances in informatics, high-throughput screening (HTS) technologies, and systems biology, the U.S. Environmental Protection Agency EPA is developing robust and flexible computational tools that can be applied to the thousands of chemicals in commerce, and contaminant mixtures found in air, water, and hazardous-waste sites. The Office of Research and Development (ORD) Computational Toxicology Research Program (CTRP) is composed of three main elements. The largest component is the National Center for Computational Toxicology (NCCT), which was established in 2005 to coordinate research on chemical screening and prioritization, informatics, and systems modeling. The second element consists of related activities in the National Health and Environmental Effects Research Laboratory (NHEERL) and the National Exposure Research Laboratory (NERL). The third and final component consists of academic centers working on various aspects of computational toxicology and funded by the U.S. EPA Science to Achieve Results (STAR) program. Together these elements form the key components in the implementation of both the initial strategy, A Framework for a Computational Toxicology Research Program (U.S. EPA, 2003), and the newly released The U.S. Environmental Protection Agency's Strategic Plan for Evaluating the T

Despite the long history of cancer screening in Japan, the participation rates in gastric and colorectal cancer screenings have not increased. Strategies for improving the participation rates have been proposed, but differences in their effects among different age groups remain unclear. The Japanese government conducted a national survey in all municipalities in Japan in 2010 to investigate whether the implementation of promotion strategies increased participation in cancer screening. We investigated the association between age factors and strategies for promoting participation in cancer screening based on this national survey. Multiple regression analysis with generalized linear model was performed using the participation rates in gastric and colorectal cancer screenings as dependent variables, and the following strategies for promoting participation as independent variables: 1) personal invitation letters, 2) household invitation letters, 3) home visits by community nurses, 4) screenings in medical offices, and 5) free cancer screening programs. One thousand six hundred thirty nine municipalities for gastric cancer screening and 1666 municipalities for colorectal cancer screening were selected for the analysis. In gastric and colorectal cancer screenings, the participation rates of individuals aged 60-69 years was higher than those of other age groups. Personal and household invitation letters were effective promotion strategies for all age groups, which encouraged even older people to participate in gastric and colorectal cancer screenings. Screening in medical offices and free screenings were not effective in all age groups. Home visits were effective, but their adoption was limited to small municipalities. To clarify whether promotion strategies can increase the participation rate in cancer screening among different age groups, 5 strategies were assessed on the basis of a national survey. Although personal and household invitation letters were effective strategies for promoting participation in cancer screening for all age groups, these strategies equally encouraged older people to participate in gastric and colorectal cancer screenings. If resource for sending invitation letters are limited, priority should be given to individuals who are in their 50s and 60s for gastric and colorectal cancer screening.

Athletic Trainers' Attitudes Toward Drug Screening of Intercollegiate Athletes

Since the inception of NCAA-mandated drug screening in 1986, college athletic trainers have found themselves involved at various levels in institutional drug-screening programs. Several legal, moral, and ethical questions have been raised regarding the drug screening of college athletes, and studies have been conducted to rate athletes' attitudes toward this practice. We examined the responses of certified athletic trainers employed in college settings to ascertain their attitudes toward the drug screening of athletes in general, and, specifically, how they view their role in this process. Surveys were distributed to 500 college athletic trainers randomly selected from the membership database maintained by the National Athletic Trainers' Association, Inc (Dallas, TX). The results of this survey indicate that the majority of athletic trainers feel that their association with the drug-screening process places them in the dual role of police and counselor, but that this relationship does not negatively affect their rapport with their athletes. Opinions regarding the drug-screening process and the importance of education in deterring drug use are somewhat dependent upon the athletic trainer's involvement in the drug-screening process. Athletic trainers possess a stronger desire to serve as resource persons who organize substance abuse education programs rather than serving as administrators of the sampling process. PMID:16558274

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.

Maintaining quality in the UK breast screening program

2010-02-01

Breast screening in the UK has been implemented for over 20 years and annually nearly two million women are now screened with an estimated 1,400 lives saved. Nationally, some 700 individuals interpret screening mammograms in almost 110 screening centres. Currently, women aged 50 to 70 are invited for screening every three years and by 2012 this age range will increase to 47 - 73 years. There is a rapid ongoing transition from using film mammograms to full field digital mammography such that in 2010 every screening centre will be partly digital. An early, and long running, concern has been how to ensure the highest quality of imaging interpretation across the UK, an issue enhanced by the use of a three year screening interval. To partly address this question a self assessment scheme was developed in 1988 and subsequently implemented nationally in the UK as a virtually mandatory activity. The scheme is detailed from its beginnings, through its various developments to current incarnation and future plans. This encompasses both radiological (single view screening, two view screening, mammographic film and full field digital mammography) as well as design changes (cases reported by means of: form filling; PDA; tablet PC; iPhone, and the internet). The scheme provides a rich data source which is regularly studied to examine different aspects of radiological performance. Overall it aids screening radiologists by giving them regular access to a range of difficult exemplar cases together with feedback on their performance as compared to their peers.

2008-06-01

To demonstrate the need for standardized data definitions and reporting for early hearing detection and intervention (EHDI) programs collecting information on newborn hearing screening and follow-up, and types of information best collected in a standardized manner. A hypothetical birth cohort was used to show the potential effects of nonstandardized definitions and data classifications on rates of hearing screening, audiologic follow-up, and hearing loss. The true screening rate in this cohort was 92.4%. The calculated rate was between 90.0% and 96.5%, depending on the measure used. Among children documented as screened and referred for follow-up, 61.0% received this testing. Only 49.0% were documented to have been tested. Despite a true prevalence of 3.7 per 1,000 births, only 1.5 per 1,000 children were documented with a hearing loss. Ensuring that children receive recommended follow-up is challenging. Without complete reporting by audiologists to EHDI programs, accurate calculation of performance measures is impossible. Lack of documentation can lead to the overstatement of "loss to follow-up." Also, standardization of measures is essential for programs to evaluate how many children receive recommended services and assess progress toward national goals. A new survey has been implemented to collect more detailed and standardized information about recommended services.

National organizations recommend pediatricians screen for food insecurity (FI). Although there has been growing research in urban practices, little research has addressed FI screening in suburban practices. We evaluated the feasibility, acceptability, and impact of screening in suburban practices. We conducted a mixed methods study that implemented FI screening in 6 suburban pediatric primary care practices. We included all children presenting for either a 2-, 15-, or 36-month well-child visit ( N = 5645). Families who screened positive were eligible to be referred to our community partner that worked to connect families to the Supplemental Nutrition Assistance Program. We conducted focus groups with clinicians to determine their perceptions of screening and suggestions for improvement. Of the 5645 children eligible, 4371 (77.4%) were screened, of which 122 (2.8%) screened positive for FI (range: 0.9%-5.9% across practices). Of the 122 food-insecure families, only 1 received new Supplemental Nutrition Assistance Program benefits. In focus groups, 3 themes emerged: (1) Time and workflow were not barriers to screening, but concerns about embarrassing families and being unable to provide adequate resources were; (2) Clinicians reported that parents felt the screening showed caring, which reinforced clinicians' continued screening; (3) Clinicians suggested implementing screening before the visit. We found it is feasible and acceptable for clinicians to screen for FI in suburban practices, but the referral method used in this study was ineffective in assisting families in obtaining benefits. Better approaches to connect families to local resources may be needed to maximize the effectiveness of screening in suburban settings. Copyright © 2017 by the American Academy of Pediatrics.

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.

To evaluate the Turkey's nationwide HPV DNA screening program on the basis of first 1 million screened women. Women over age 30 were invited for population based screening via HPV DNA and conventional cytology. Samples were collected by family physicians and the evaluations and reports had been performed in the National Central HPV laboratories. The acceptance rate for HPV based cervical cancer screening after first invitation was nearly 36.5%. Since HPV DNA tests have been implemented, cervical cancer screening rates have shown 4-5-fold increase in primary level. Through the evaluation of all, HPV positivity was seen in 3.5%. The commonest HPV genotypes were 16, followed by 51, 31, 52 and 18. Among the 37.515 HPV positive cases, cytological abnormality rate was 19.1%. Among HPV positive cases, 16.962 cases had HPV 16 or 18 or other oncogenic HPV types with abnormal cytology (>ASC-US). These patients were referred to colposcopy. The colposcopy referral rate was 1.6%. Among these, final clinico-pathological data of 3.499 patients were normal in 1.985 patients, CIN1 in 708, CIN2 in 285, CIN3 in 436 and cancer in 85 patients and only pap-smear program could miss 45.9% of ≥CIN3 cases. The results of 1 million women including the evaluation of 13 HPV genotypes with respect to prevalence, geographic distribution and abnormal cytology results shows that HPV DNA can be used in primary level settings to have a high coverage rated screening program and is very effective compared to conventional pap-smear. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

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.

In Korea, the nationwide gastric cancer screening program recommends biennial screening for individuals aged 40 years or older by way of either an upper gastrointestinal series or endoscopy. The national endoscopic quality assessment (QA) program began recommending endoscopy in medical institutions in 2009. We aimed to assess the effect, burden, and cost of the QA program from the viewpoint of medical institutions. We surveyed the staff of institutional endoscopic units via e-mail. Staff members from 67 institutions replied. Most doctors were endoscopic specialists. They responded as to whether the QA program raised awareness for endoscopic quality (93%) or improved endoscopic practice (40%). The percentages of responders who reported improvements in the diagnosis of gastric cancer, the qualifications of endoscopists, the quality of facilities and equipment, endoscopic procedure, and endoscopic reprocessing were 69%, 60%, 66%, 82%, and 75%, respectively. Regarding reprocessing, many staff members reported that they had bought new automated endoscopic preprocessors (3%), used more disinfectants (34%), washed endoscopes longer (28%), reduced the number of endoscopies performed to adhere to reprocessing guidelines (9%), and created their own quality education programs (59%). Many responders said they felt that QA was associated with some degree of burden (48%), especially financial burden caused by purchasing new equipment. Reasonable quality standards (45%) and incentives (38%) were considered important to the success of the QA program. Endoscopic quality has improved after 5 years of the mandatory endoscopic QA program.

Gastric cancer (GC) is still an important global healthcare problem, and in absolute figures it is going to remain at the present level in foreseeable future. In general, survival of patients with GC is poor mainly due to advanced-stage diagnosis. Early-stage GC can be cured by endoscopic resection or less invasive surgical treatment. Unfortunately, there is no appropriate screening strategy available for global application. This article provides a description of established national and regional GC screening programs and the screening modalities used. This review also summarizes current approaches to develop cancer-screening biomarkers. Although candidates with initial promising results have been suggested, moving discovery into clinical practice is still a major challenge. Well-designed biomarker studies, with systematic validation steps, are needed to decrease the burden of this fatal disease. PMID:25439074

Background: States vary widely in their use of newborn screening tests, with some mandating screening for as few as three conditions and others mandating as many as 43 conditions, including varying numbers of the 40+ conditions that can be detected by tandem mass spectrometry (MS/MS). There has been no national guidance on the best candidate conditions for newborn screening since the National Academy of Sciences report of 19751 and the United States Congress Office of Technology Assessment report of 1988,2 despite rapid developments since then in genetics, in screening technologies, and in some treatments. Objectives: In 2002, the Maternal and Child Health Bureau (MCHB) of the Health Resources and Services Administration (HRSA) of the United States Department of Health and Human Services (DHHS) commissioned the American College of Medical Genetics (ACMG) to: Conduct an analysis of the scientific literature on the effectiveness of newborn screening.Gather expert opinion to delineate the best evidence for screening for specified conditions and develop recommendations focused on newborn screening, including but not limited to the development of a uniform condition panel.Consider other components of the newborn screening system that are critical to achieving the expected outcomes in those screened. Methods: A group of experts in various areas of subspecialty medicine and primary care, health policy, law, public health, and consumers worked with a steering committee and several expert work groups, using a two-tiered approach to assess and rank conditions. A first step was developing a set of principles to guide the analysis. This was followed by developing criteria by which conditions could be evaluated, and then identifying the conditions to be evaluated. A large and broadly representative group of experts was asked to provide their opinions on the extent to which particular conditions met the selected criteria, relying on supporting evidence and references from the scientific literature. The criteria were distributed among three main categories for each condition: The availability and characteristics of the screening test;The availability and complexity of diagnostic services; andThe availability and efficacy of treatments related to the conditions. A survey process utilizing a data collection instrument was used to gather expert opinion on the conditions in the first tier of the assessment. The data collection format and survey provided the opportunity to quantify expert opinion and to obtain the views of a diverse set of interest groups (necessary due to the subjective nature of some of the criteria). Statistical analysis of data produced a score for each condition, which determined its ranking and initial placement in one of three categories (high scoring, moderately scoring, or low scoring/absence of a newborn screening test). In the second tier of these analyses, the evidence base related to each condition was assessed in depth (e.g., via systematic reviews of reference lists including MedLine, PubMed and others; books; Internet searches; professional guidelines; clinical evidence; and cost/economic evidence and modeling). The fact sheets reflecting these analyses were evaluated by at least two acknowledged experts for each condition. These experts assessed the data and the associated references related to each criterion and provided corrections where appropriate, assigned a value to the level of evidence and the quality of the studies that established the evidence base, and determined whether there were significant variances from the survey data. Survey results were subsequently realigned with the evidence obtained from the scientific literature during the second-tier analysis for all objective criteria, based on input from at least three acknowledged experts in each condition. The information from these two tiers of assessment was then considered with regard to the overriding principles and other technology or condition-specific recommendations. On the basis of this information, conditions were assigned to one of three categories as described above:Core Panel;Secondary Targets (conditions that are part of the differential diagnosis of a core panel condition.); andNot Appropriate for Newborn Screening (either no newborn screening test is available or there is poor performance with regard to multiple other evaluation criteria). ACMG also considered features of optimal newborn screening programs beyond the tests themselves by assessing the degree to which programs met certain goals (e.g., availability of educational programs, proportions of newborns screened and followed up). Assessments were based on the input of experts serving in various capacities in newborn screening programs and on 2002 data provided by the programs of the National Newborn Screening and Genetics Resource Center (NNSGRC). In addition, a brief cost-effectiveness assessment of newborn screening was conducted. Results: Uniform panel A total of 292 individuals determined to be generally representative of the regional distribution of the United States population and of areas of expertise or involvement in newborn screening provided a total of 3,949 evaluations of 84 conditions. For each condition, the responses of at least three experts in that condition were compared with those of all respondents for that condition and found to be consistent. A score of 1,200 on the data collection instrument provided a logical separation point between high scoring conditions (1,200–1,799 of a possible 2,100) and low scoring (<1,000) conditions. A group of conditions with intermediate scores (1,000–1,199) was identified, all of which were part of the differential diagnosis of a high scoring condition or apparent in the result of the multiplex assay. Some are identified by screening laboratories and others by diagnostic laboratories. This group was designated as a “secondary target” category for which the program must report the diagnostic result. Using the validated evidence base and expert opinion, each condition that had previously been assigned to a category based on scores gathered through the data collection instrument was reconsidered. Again, the factors taken into consideration were: 1) available scientific evidence; 2) availability of a screening test; 3) presence of an efficacious treatment; 4) adequate understanding of the natural history of the condition; and 5) whether the condition was either part of the differential diagnosis of another condition or whether the screening test results related to a clinically significant condition. The conditions were then assigned to one of three categories as previously described (core panel, secondary targets, or not appropriate for Newborn Screening). Among the 29 conditions assigned to the core panel are three hemoglobinopathies associated with a Hb/S allele, six amino acidurias, five disorders of fatty oxidation, nine organic acidurias, and six unrelated conditions (congenital hypothyroidism (CH), biotinidase deficiency (BIOT), congenital adrenal hyperplasia (CAH), classical galactosemia (GALT), hearing loss (HEAR) and cystic fibrosis (CF)). Twenty-three of the 29 conditions in the core panel are identified with multiplex technologies such as tandem mass spectrometry (MS/MS) or high pressure liquid chromatography (HPLC). On the basis of the evidence, six of the 35 conditions initially placed in the core panel were moved into the secondary target category, which expanded to 25 conditions. Test results not associated with potential disease in the infant (e.g., carriers) were also placed in the secondary target category. When newborn screening laboratory results definitively establish carrier status, the result should be made available to the health care professional community and families. Twenty-seven conditions were determined to be inappropriate for newborn screening at this time. Conditions with limited evidence reported in the scientific literature were more difficult to evaluate, quantify and place in one of the three categories. In addition, many conditions were found to occur in multiple forms distinguished by age-of-onset, severity, or other features. Further, unless a condition was already included in newborn screening programs, there was a potential for bias in the information related to some criteria. In such circumstances, the quality of the studies underlying the data such as expert opinion that considered case reports and reasoning from first principles determined the placement of the conditions into particular categories. Newborn screening program optimization – Assessment of the activities of newborn screening programs, based on program reports, was done for the six program components: education; screening; follow-up; diagnostic confirmation; management; and program evaluation. Considerable variation was found between programs with regard to whether particular aspects (e.g., prenatal education program availability, tracking of specimen collection and delivery) were included and the degree to which they are provided. Newborn screening program evaluation systems also were assessed in order to determine their adequacy and uniformity with the goal being to improve interprogram evaluation and comparison to ensure that the expected outcomes from having been identified in screening are realized. Conclusions: The state of the published evidence in the fast-moving worlds of newborn screening and medical genetics has not kept up with the implementation of new technologies, thus requiring the considerable use of expert opinion to develop recommendations about a core panel of conditions for newborn screening. Twenty-nine conditions were identified as primary targets for screening from which all components of the newborn screening system should be maximized. An additional 25 conditions were listed that could be identified in the course of screening for core panel conditions. Programs are obligated to establish a diagnosis and communicate the result to the health care provider and family. It is recognized that screening may not have been maximized for the detection of these secondary conditions but that some proportion of such cases may be found among those screened for core panel conditions. With additional screening, greater training of primary care health care professionals and subspecialists will be needed, as will the development of an infrastructure for appropriate follow-up and management throughout the lives of children who have been identified as having one of these rare conditions. Recommended actions to overcome barriers to an optimal newborn screening system include: The establishment of a national role in the scientific evaluation of conditions and the technologies by which they are screened;Standardization of case definitions and reporting procedures;Enhanced oversight of hospital-based screening activities;Long-term data collection and surveillance; andConsideration of the financial needs of programs to allow them to deliver the appropriate services to the screened population.

Introduction On the basis of results from the National Lung Screening Trial (NLST), national guidelines now recommend using low-dose computed tomography (LDCT) to screen high-risk smokers for lung cancer. Our study objective was to characterize the knowledge, attitudes, and beliefs of primary care providers about implementing LDCT screening. Methods We conducted semistructured interviews with primary care providers practicing in New Mexico clinics for underserved minority populations. The interviews, conducted from February through September 2014, focused on providers’ tobacco cessation efforts, lung cancer screening practices, perceptions of NLST and screening guidelines, and attitudes about informed decision making for cancer screening. Investigators iteratively reviewed transcripts to create a coding structure. Results We reached thematic saturation after interviewing 10 providers practicing in 6 urban and 4 rural settings; 8 practiced at federally qualified health centers. All 10 providers promoted smoking cessation, some screened with chest x-rays, and none screened with LDCT. Not all were aware of NLST results or current guideline recommendations. Providers viewed study results skeptically, particularly the 95% false-positive rate, the need to screen 320 patients to prevent 1 lung cancer death, and the small proportion of minority participants. Providers were uncertain whether New Mexico had the necessary infrastructure to support high-quality screening, and worried about access barriers and financial burdens for rural, underinsured populations. Providers noted the complexity of discussing benefits and harms of screening and surveillance with their patient population. Conclusion Providers have several concerns about the feasibility and appropriateness of implementing LDCT screening. Effective lung cancer screening programs will need to educate providers and patients to support informed decision making and to ensure that high-quality screening can be efficiently delivered in community practice.

Inspired by the Hygienist Movement, which associates good health with regular, moderate exercise, the National Health and Nutrition Program identifies a lack of physical activity as a risk factor for many chronic diseases. As such, the Program encourages people to take care of their bodies by inciting a moral obligation to develop a physically active lifestyle and follow a healthy diet. With the overall goal of improving the health of the population by acting on nutrition, the Program focuses on primary prevention, screening and early treatment of conditions like heart disease, cancer, obesity, osteoporosis and diabetes. As an incentive program developed in keeping with the biopolitical views of the 1970s that saw education as an alternative means to hospitals for achieving good health, the Program is also a good public action tool for controlling costs.

On the basis of the National Lung Screening Trial data released in 2011, the U.S. Preventive Services Task Force made lung cancer screening (LCS) with low-dose computed tomography (CT) a public health recommendation in 2013. The Centers for Medicare and Medicaid Services (CMS) currently reimburse LCS for asymptomatic individuals aged 55-77 years who have a tobacco smoking history of at least 30 pack-years and who are either currently smoking or had quit less than 15 years earlier. Commercial insurers reimburse the cost of LCS for individuals aged 55-80 years with the same smoking history. Effective care for the millions of Americans who qualify for LCS requires an organized step-wise approach. The 10-pillar model reflects the elements required to support a successful LCS program: eligibility, education, examination ordering, image acquisition, image review, communication, referral network, quality improvement, reimbursement, and research frontiers. Examination ordering can be coupled with decision support to ensure that only eligible individuals undergo LCS. Communication of results revolves around the Lung Imaging Reporting and Data System (Lung-RADS) from the American College of Radiology. Lung-RADS is a structured decision-oriented reporting system designed to minimize the rate of false-positive screening examination results. With nodule size and morphology as discriminators, Lung-RADS links nodule management pathways to the variety of nodules present on LCS CT studies. Tracking of patient outcomes is facilitated by a CMS-approved national registry maintained by the American College of Radiology. Online supplemental material is available for this article.

The dairy industry is faced with increasing governmental and public concern about the safety of the nation's milk supply. New regulations under the Grade A Pasteurized Milk Ordinance require that prescription drugs be properly labeled and that all tanker loads of milk be tested for beta-lactam antimicrobial residues. Concern over the use of animal drugs in an extralabel manner has prompted the National Milk Producers Federation and the American Veterinary Medical Association to develop a quality assurance program for on-farm residue prevention known as the Dairy Quality Assurance 10-Point Milk and Dairy Beef Residue Prevention Protocol. The program promotes the concept of Hazard Analysis Critical Control Points, applied to a pre-harvest farm environment. Screening limitations at point of milk receipt necessitates widespread adoption of the Dairy Quality Assurance protocol to address controlled use of all animal medications under a valid relationship among veterinarian, client, and animals, thus minimizing the potential for violative residues in the milk and meat supply.

Cervical cancer is the third most common gynecological malignancy in Saudi women with an estimated incidence rate of 1.9 cases per 100 000 women-years. More than 40% of cervical cancer cases are diagnosed at advanced stages due to lack of a routine screening program in Saudi Arabia. Thus, national guidelines for routine screening and treatment of precancerous cervical lesions are needed. The Saudi Centre for Evidence-Based Healthcare invited a panel of local experts and partnered them with a team from McMaster University in Canada for methodological support, to develop national clinical practice guidelines on the screening and treatment of precancerous lesions for cervical cancer. After the panel identified key clinical questions, the McMaster University working group updated existing systematic reviews that had been used for the 2013 WHO Guidelines for screening and treatment of precancerous lesions for cervical cancer prevention. Recommendations were based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. Those recommendations took into account the available evidence, patient values and preferences, and resource use in the Saudi context. The panel provided recommendations on two major issues: screening for precancerous lesions (cervical intraepithelial neoplasia 2 & 3) and treatment of those lesions to prevent cervical cancer in women who tested positive after screening. The Saudi expert panel recommends using the HPV DNA test followed by colposcopy or cytology (Pap test) followed by colposcopy to screen for CIN2+ in women at risk of cervical cancer. The panel recommends cryotherapy or loop excision electrosurgery procedure (LEEP) over cold knife cone biopsy to treat women at risk of cervical cancer that tests positive for CIN2+. Universal screening for precancerous cervical dysplasia in women in Saudi Arabia is recommended using HPV testing and or cytology. Either cryotherapy or LEEP are preferred for treatment. National studies on cervical cancer screening modalities and treatment of precancerous cervical lesions, including HPV prevalence and its association with cervical cancer, are scarce.

Objective To review evidence on the workplace prevalence and correlates of major depressive episodes, with a particular focus on the National Comorbidity Survey Replication, the most recent national survey to focus on these issues. Method Nationally representative survey of Diagnostic and Statistical Manual, 4th Revision Mental Disorders. Results A total of 6.4% of employed National Comorbidity Survey Replication respondents had 12-month major depressive disorder. An additional 1.1% had major depressive episodes due to bipolar disorder or mania– hypomania. Only about half of depressed workers received treatment. Fewer than half of treated workers received care consistent with published treatment guidelines. Conclusions Depression disease management programs can have a positive return-on-investment from the employer perspective, but only when they are based on best practices. Given the generally low depression treatment quality documented here, treatment quality guarantees are needed before expanding workplace depression screening, outreach, and treatment programs.

Spinal muscular atrophy is the most common fatal hereditary disease among newborns and infants. There is as yet no effective treatment. Although a carrier test is available, currently there is disagreement among professional medical societies who proffer standards of care as to whether or not carrier screening for spinal muscular atrophy should be offered as part of routine reproductive care. This leaves health care providers without clear guidance. In fall 2009, a meeting was held by National Institutes of Health to examine the scientific basis for spinal muscular atrophy carrier screening and to consider the issues that accompany such screening. In this article, the meeting participants summarize the discussions and conclude that pan-ethnic carrier screening for spinal muscular atrophy is technically feasible and that the specific study of implementing a spinal muscular atrophy carrier screening program raises broader issues about determining the scope and specifics of carrier screening in general.

Objectives. To determine whether the addition of hepatitis B virus (HBV) vaccine to national immunization programs improved vaccination rates among refugee children, a marginalized population with limited access to care. Methods. The sample included 2291 refugees younger than 19 years who completed HBV screening after arrival in the United States. Children were categorized by having been born before or after the addition of the 3-dose HBV vaccine to their birth country’s national immunization program. The outcome was serological evidence of immunization. Results. The odds of serological evidence of HBV immunization were higher for children born after the addition of HBV vaccine to their birth country’s national immunization program (adjusted odds ratio = 2.54; 95% confidence interval = 2.04, 3.15). Conclusions. National HBV vaccination programs have contributed to the increase in HBV vaccination coverage observed among US-bound refugee children. Public Health Implications. Ongoing public health surveillance is needed to ensure that vaccine rates are sustained among diverse, conflict-affected, displaced populations. PMID:27310356

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

PubMed

Bergeret, A; Terrasson De Fougères, G

1999-12-01

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.

Some experts have promoted preparticipative cardiovascular screening programs for young athletes and have claimed that such programs were cost-effective without performing a critical analysis of studies supporting this statement. In this systematic review, a critical assessment of economic evaluations on these programs is performed to determine if they really provide value for money. A systematic review of economic evaluations was performed on December 24, 2014. Web sites of health technology assessment agencies, the Cochrane database of systematic review, the National Health Service Economic Evaluation Database of the Cochrane Library, EMBASE, Medline, Psychinfo, and EconLit were searched to retrieve (reviews of) economic evaluations. No language or time restrictions were imposed and predefined selection criteria were used. Selected studies were critically assessed applying a structured data extraction sheet. Five relevant economic evaluations were critically assessed. Results of these studies were mixed. However, those in favor of screening made (methodological) incorrect choices, of which the most important one was not taking into account a no-screening alternative as comparator. Compared with no screening, other strategies (history and physical examination or history and physical examination plus electrocardiogram) were not considered cost-effective. Results of primary economic evaluations should not be blindly copied without critical assessment. Economic evaluations in this field lack the support of robust evidence. Negative consequences of screening (false positive findings, overtreatment) should also be taken into account and may cause more harm than good. A mass screening of young athletes for cardiovascular diseases does not provide value for money and should be discouraged.

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).

Sickle cell disease (SCD) is associated with high mortality for children under 5 years of age in sub-Saharan Africa. Newborn sickle screening program and enhanced capacity for SCD treatment are under development to reduce disease burden in Uganda and elsewhere in the region. Based on an international stakeholder meeting and a family-directed conference on SCD in Kampala in 2015, and interviews with parents, multinational experts, and other key informants, we describe health care, community, and family perspectives in support of these initiatives. Key stakeholder meetings, discussions, and interviews were held to understand perspectives of public health and multinational leadership, patients and families, as well as national progress, resource needs, medical and social barriers to program success, and resources leveraged from HIV/AIDS. Partnering with program leadership, professionals, patients and families, multinational stakeholders, and leveraging resources from existing programs are needed for building successful programs in Uganda and elsewhere in sub-Saharan Africa.

Indigenous Canadians have high rates of risk factors for chronic kidney disease (CKD), in particular diabetes. Furthermore, they have increased rates of complications associated with CKD, such as kidney failure and vascular disease. Our objective was to describe the prevalence of CKD in this population. Cross-sectional cohort. Indigenous (First Nations) Canadians 18 years or older screened as part of the First Nations Community Based Screening to Improve Kidney Health and Prevent Dialysis (FINISHED) project, an initiative completed in 2015 that accomplished community-wide screening in 11 rural communities in Manitoba, Canada. Indigenous ethnicity and geographic location (communities accessible by road compared with those accessible only by air). Prevalence of CKD, presumed based on a single ascertainment of urine albumin-creatinine ratio (UACR) ≥ 30mg/g and/or estimated glomerular filtration rate (eGFR)<60mL/min/1.73m(2). Kidney function measured by eGFR (CKD-EPI creatinine equation) and UACR. 1,346 adults were screened; 25.5% had CKD, defined as UACR≥30mg/g or eGFR<60mL/min/1.73m(2). Communities accessible by road had a lower prevalence of CKD (17.6%) than more remote communities accessible only by air (34.4%). Of those screened, 3.3% had reduced kidney function (defined as eGFR<60mL/min/1.73m(2)). Severely increased albuminuria was present in 5.0% of those screened. Presumption of chronicity based on a single ascertainment. There is a possibility of sampling bias, the net direction of which is uncertain. We found a 2-fold higher prevalence of CKD in indigenous Canadians in comparison to the general population and a prevalence of severely increased albuminuria that was 5-fold higher. This is comparable to patients with diabetes and/or hypertension. Public health strategies to screen, triage, and treat all Canadian indigenous peoples with CKD should be considered.

The Colorectal Cancer Mortality-to-Incidence Ratio as an Indicator of Global Cancer Screening and Care

PubMed Central

Sunkara, Vasu; Hébert, James R.

2015-01-01

BACKGROUND Disparities in cancer screening, incidence, treatment, and survival are worsening globally. The mortality-to-incidence ratio (MIR) has been used previously to evaluate such disparities. METHODS The MIR for colorectal cancer is calculated for all Organisation for Economic Cooperation and Development (OECD) countries using the 2012 GLOBOCAN incidence and mortality statistics. Health system rankings were obtained from the World Health Organization. Two linear regression models were fit with the MIR as the dependent variable and health system ranking as the independent variable; one included all countries and one model had the “divergents” removed. RESULTS The regression model for all countries explained 24% of the total variance in the MIR. Nine countries were found to have regression-calculated MIRs that differed from the actual MIR by >20%. Countries with lower-than-expected MIRs were found to have strong national health systems characterized by formal colorectal cancer screening programs. Conversely, countries with higher-than-expected MIRs lack screening programs. When these divergent points were removed from the data set, the recalculated regression model explained 60% of the total variance in the MIR. CONCLUSIONS The MIR proved useful for identifying disparities in cancer screening and treatment internationally. It has potential as an indicator of the long-term success of cancer surveillance programs and may be extended to other cancer types for these purposes. PMID:25572676

Population carrier screening (PCS) has been available in Israel since 1999 and universally subsidized since 2008. We sought to evaluate its impact. A retrospective review of governmental databanks, the national CF registry and CF centers. CF rate per 100,000 live births has decreased from 14.5 in 1990 to 6 in 2011. From 2004-2011 there were 95 CF births: 22 utilized PCS; 68 (72%) had 2 known CFTR mutations; 37% were pancreatic sufficient. At diagnosis, age was 6 (0-98) months; 53/95 had respiratory symptoms, 41/95 failure to thrive and 19/95 pseudomonas. Thirty-four (36%) were Arabs and 19 (20%) orthodox Jews, compared to 20% and 8% respectively, in the general population. PCS markedly reduced CF birth rates with a shift towards milder mutations, but was often avoided for cultural reasons. As children regularly have significant disease at diagnosis, we suggest a balanced approach, utilizing both PCS and newborn screening. Copyright © 2015 European Cystic Fibrosis Society.

EPA RE-Powering Screening Shapefile

EPA Pesticide Factsheets

The U.S. Environmental Protection Agency (EPA) Office of Land and Emergency Management (OLEM) Center for Program Analysis (CPA) initiated the RE-Powering America??s Land Initiative to demonstrate the enormous potential that contaminated lands, landfills, and mine sites provide for developing renewable energy in the United States. EPA developed national level site screening criteria in partnership with the U.S. Department of Energy (DOE) National Renewable Energy Laboratory (NREL) for wind, solar, biomass, and geothermal facilities. While the screening criteria demonstrate the potential to reuse contaminated land for renewable energy facilities, the criteria and data are neither designed to identify the best sites for developing renewable energy nor all-inclusive. Therefore, more detailed, site-specific analysis is necessary to identify or prioritize the best sites for developing renewable energy facilities based on the technical and economic potential. Please note that these sites were only pre-screened for renewable energy potential. The sites were not evaluated for land use constraints or current on the ground conditions. Additional research and site-specific analysis are needed to verify viability for renewable energy potential at a given site.

Engaging Overweight Adolescents in a Health and Fitness Program Using Wearable Activity Trackers.

Wilson, Marian; Ramsay, Samantha; Young, Kimberly J

Our objectives were to (a) examine feasibility and receptivity of overweight adolescents joining a community-based group fitness program and (b) test preliminary efficacy of a 12-week pilot intervention designed to promote health, fitness, and self-efficacy for the identified teens. The 12-week fitness program for overweight adolescents was developed and included planned physical activities, nutrition classes, and goal-setting sessions. A one-group pre-/posttest study design evaluated 20 participants from grades 10 through 12 who enrolled in the program pilot study. Participants were given a wearable activity tracker that captured data using an Internet-based platform. Outcome measures included body mass index, screen time, fitness, and cardiovascular measures. A community fitness program for overweight adolescents was successfully implemented. High school students were receptive to the intervention and reported high program satisfaction. Positive effects included measurements of strength, systolic blood pressure, weight, and screen time behaviors. This study provides evidence to support the feasibility, acceptance, and preliminary effects of the pilot program with overweight adolescents.

Quality Assurance Through Quality Improvement and Professional Development in the National Breast and Cervical Cancer Early Detection Program

PubMed Central

Siegl, Elvira J.; Miller, Jacqueline W.; Khan, Kris; Harris, Susan E.

2015-01-01

Quality assurance (QA) is the process of providing evidence that the outcome meets the established standards. Quality improvement (QI), by contrast, is the act of methodically developing ways to meet acceptable quality standards and evaluating current processes to improve overall performance. In the case of the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), the desired outcome is the delivery of quality health care services to program clients. The NBCCEDP provides professional development to ensure that participating providers have current knowledge of evidence-based clinical standards regarding breast and cervical cancer screening and diagnosis and are monitoring women with abnormal screening results for timely follow-up. To assess the quality of clinical care provided to NBCCEDP clients, performance data are collected by NBCCEDP grantees and compared against predetermined Centers for Disease Control and Prevention (CDC) benchmarks known as Data Quality Indicator Guides. In this article, the authors describe 1) the development and use of indicators for QI in the NBCCEDP and 2) the professional development activities implemented to improve clinical outcomes. QA identifies problems, whereas QI systematically corrects them. The quality of service delivery and improved patient outcomes among NBCCEDP grantees has enhanced significantly because of continuous monitoring of performance and professional development. By using QA, NBCCEDP grantees can maximize the quality of patient screening, diagnostic services, and follow-up. Examples of grantee activities to maintain quality of care are also described in this report. PMID:25099901

Evidence-based practices in the workplace can increase levels of healthy eating, cancer screening, physical activity, and tobacco cessation but are underused, even in large workplaces. This report summarizes an evaluation of the first year of The CEOs Challenge, a program developed by the American Cancer Society to promote implementation and maintenance of health-promoting, evidence-based workplace practices by large companies. Use of 17 evidence-based practices by 17 companies in the Washington State Chapter of the American Cancer Society's CEOs Against Cancer network was assessed via survey and scored from 0 to 100. Companies received a written report of their baseline performance, followed by at least quarterly consultations with American Cancer Society staff members trained to assist in implementation of these practices. Follow-up performance was measured at 1 year. At baseline, implementation scores were 54.8 for cancer screening, 46.5 for healthy eating, 59.8 for physical activity, and 68.2 for tobacco cessation. At follow-up, scores increased by 19.6 for cancer screening, 19.4 for healthy eating, 16.0 for physical activity, and 9.4 points for tobacco cessation. The CEOs Challenge is a promising approach to chronic disease prevention via the workplace. It brings together one of the nation's largest health-promoting voluntary agencies with the nation's largest employers to promote evidence-based practices targeted at the most common causes of disease and death. The program increased the adoption of these practices and was well-accepted.

National G6PD neonatal screening program in Gaza Strip of Palestine: rationale, challenges and recommendations.

Congenital genetic disorders affecting neonates or young children can have serious clinical consequences if undiagnosed and left untreated. Early detection and an accurate diagnosis are, therefore, of major importance for preventing negative patient outcomes. Even though the occurrence of each specific metabolic disorder may be rare, their collective impact of preventable complications may be of considerable importance to the public health. Our previous studies showed that glucose-6-phosphate dehydrogenase (G6PD) deficiency is a problem of public health importance that has been shown to be a predominant cause of acute hemolytic anemia requiring hospitalization in Palestinian young children in Gaza Strip. Intriguingly, the majority of these children had one of the three variants, Mediterranean(c.) (563T) , African G6PD A-(c.) (202A) (/c.) (376G) and heretofore unrecognized as a common G6PD-deficient variant G6PD Cairo(c.) (404C) . The high prevalence of G6PD deficiency, as well as dietary factors in the region that precipitate anemia, argues for a need to protect the Palestinian children from a treatable and manageable genetic and metabolic disorder. This work reviews and discusses rationales and challenges of G6PD screening program in Gaza Strip. We advocate adopting a national neonatal G6PD screening program in Gaza Strip to identify children at risk and promote wellness and health for Palestine. © 2016 John Wiley & Sons A/S.

Congenital hypothyroidism (CH) is a common cause of mental retardation; it has a worldwide incidence ranging from 1:3000 to 1:4500 live births. Predictably, an increase in the reported incidence of primary CH occurs when the cut-off levels of thyroid-stimulating hormone are lowered. We aimed to evaluate the results of a congenital hypothyroidism screening program and current status in this study. Analysis results of 1300 infants who were referred to the endocrinology polyclinic because of suspected CH within the scope of the Ministry of Health National Neonatal Screening Program were retrospectively evaluated. The diagnosis of CH and initiation of treatment were both done in 223 (18.5%) and 10 (0.8%) infants as a result of the initial evaluation and follow-up, respectively. The mean capillary and venous thyroid-stimulating hormone (TSH) levels of 223 patients were 40.78 (5.5-100) μIU/mL and 67.26 (10.7-100) μIU/mL, respectively. These patients' mean heel prick time was 8.65 (0-30, median: 7) days. The mean age of the 223 infants whose treatment was initiated as a result of the initial evaluation was 19.87 (4-51, median: 20) days, and the mean age of the infants whose treatment was started at follow-up was 43.71 (29-65) days. The duration between heel prick time and venous TSH time was 11.10 (2-28, median: 11) days and was longer than planned (3-5 days). Although the duration for the diagnosis and initiation of CH treatment were markedly reduced with the implementation of the screening program in Turkey compared to those before the implementation of the screening program, we have not yet achieved the ideal time (≤14 days).

Biliary atresia (BA) is a significant liver disease in children. Since 2004, Taiwan has implemented a national screening program that uses an infant stool color card (SCC) for the early detection of BA. The purpose of this study was to examine the outcomes of BA cases before and after the launch of this screening program. The objectives of this study were to evaluate the rates of hospitalization, liver transplantation (LT), and mortality of BA cases before and after the program, and to examine the association between the hospitalization rate and survival outcomes.This was a population-based cohort study. BA cases born during 1997 to 2010 were identified from the Taiwan National Health Insurance Research Database. Sex, birth date, hospitalization date, LT, and death data were collected and analyzed. The hospitalization rate by 2 years of age (Hosp/2yr) was calculated to evaluate its association with the outcomes of LT or death.Among 513 total BA cases, 457 (89%) underwent the Kasai procedure. Of these, the Hosp/2yr was significantly reduced from 6.0 to 6.9/case in the earlier cohort (1997-2004) to 4.9 to 5.3/case in the later cohort (2005-2010). This hospitalization rate reduction was followed by a reduction in mortality from 26.2% to 15.9% after 2006. The Cox proportional hazards model showed a significant increase in the risk for both LT (hazard ratio [HR] = 1.14, 95% confidence interval [CI] = 1.10-1.18) and death (HR = 1.05, 95% CI = 1.01-1.08) for each additional hospitalization. A multivariate logistic regression model found that cases with a Hosp/2yr >6 times had a significantly higher risk for both LT (adjusted odds ratio [aOR] = 4.35, 95% CI = 2.82-6.73) and death (aOR = 1.75, 95% CI = 1.17-2.62).The hospitalization and mortality rates of BA cases in Taiwan were significantly and coincidentally reduced after the launch of the SCC screening program. There was a significant association between the hospitalization rate and final outcomes of LT or death. The SCC screening program can help reduce the hospitalization rate and mortality of BA cases and bring great financial benefit.

EJSCREEN Version 1, Primary EJ Index

EPA Pesticide Factsheets

The primary EJ index measures how much a particular place contributes to overall nationwide differences in environmental indicator values between demographic groups. This EJ index is a combination of a block group environmental factor, the population of the block group, and the demographic composition of the block group. In this index, the demographic composition of the block group is the difference between the block group??s composition and the national average, as measured by the primary demographic index. EJSCREEN is an environmental justice screening tool that provides EPA with a nationally consistent approach to screening for potential areas of EJ concern that may warrant further investigation. The EJ indexes are block group level results that combine multiple demographic factors with a single environmental variable (such as proximity to traffic) that can be used to help identify communities living with the greatest potential for negative environmental and health effects. The EJSCREEN tool is currently for internal EPA use only. It is anticipated that as users become accustomed to this new tool, individual programs within the Agency will develop program use guidelines and a community of practice will develop around them within the EPA Geoplatform. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas, such as Census block group

Introduction. The incidence of genetic blood disease in Bahrain has declined gradually since 1984 when the Ministry of Health (MOH) instituted a prevention campaign. The national NBS program for hemoglobinopathies was started in May 2007, financed by the national budget. Setting. Genetics department, Salmaniya Medical Complex, MOH, Bahrain. Methodology. The genetics, nursing, pathology, and pediatric departments were involved in the study. This service was offered to all infants. Cord blood samples were collected at birth and were then sent to the laboratory. Results. During 3.5 years after the program was implemented, we screened 38,940 newborns (NBs), of which 17,375 were screened in 2008, 10,248 in 2009, and 11,317 in 2010. The number of affected NBs was 128 in both 2007 and 2008, 58 in 2009, and 47 in 2010, as the average number of affected NBs in 2010 was 4 per month. The incidence of affected NBs was found to be 0.7% in 2008, 0.6% in 2009, and 0.4% in 2010. Conclusion. NBS is an essential step for the early diagnosis and treatment of affected NBs, future recurrence of the disease in the same family. In Bahrain, the number of affected NBs has declined by 75% during the last 20. PMID:22550494

EJSCREEN Version 1, Environmental Data

This map service displays raw environmental data for the 12 environmental indicators used in EJSCREEN. The map service displays percentiles for each of the environmental indicators to provide perspective on how a selected location compares to the entire nation. EJSCREEN is an environmental justice screening tool that provides EPA with a nationally consistent approach to screening for potential areas of EJ concern that may warrant further investigation. The EJ indexes are block group level results that combine multiple demographic factors with a single environmental variable (such as proximity to traffic) that can be used to help identify communities living with the greatest potential for negative environmental and health effects. The EJSCREEN tool is currently for internal EPA use only. It is anticipated that as users become accustomed to this new tool, individual programs within the Agency will develop program use guidelines and a community of practice will develop around them within the EPA Geoplatform. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas, such as Census block groups. Data on the full range of environmental impacts and demographic factors in any given location are almost certainly not available directly through this tool, and its initial results should be supplemented with additional information and local knowledge

The aim of this study is to evaluate the cost-effectiveness of a patient-direct mailed advance notification letter on participants of a National Bowel Cancer Screening Program (NBCSP) in Australia, which was launched in August 2006 and offers free fecal occult blood testing to all Australians turning 50, 55, or 65 years of age in any given year. This study followed a hypothetical cohort of 50-year-old, 55-year-old, and 65-year-old patients undergoing fecal occult blood test (FOBT) screening through a decision analytic Markov model. The intervention compared two strategies: (i) advance letter, NBCSP, and FOBT compared with (ii) NBCSP and FOBT. The main outcome measures were life-years gained (LYG), quality-adjusted life-years (QALYs) gained and incremental cost-effectiveness ratio. An advance notification screening letter would yield an additional 54 per 100,000 colorectal cancer deaths avoided compared with no letter. The estimated cost-effectiveness was $3,976 per LYG and $6,976 per QALY gained. An advance notification letter in the NBCSP may have a significant impact on LYG and cancer deaths avoided. It is cost-effective and offers a feasible strategy that could be rolled out across other screening program at an acceptable cost.

Inspired by the Hygienist Movement, which associates good health with regular, moderate exercise, the National Health and Nutrition Program identifies a lack of physical activity as a risk factor for many chronic diseases. As such, the Program encourages people to take care of their bodies by inciting a moral obligation to develop a physically active lifestyle and follow a healthy diet. With the overall goal of improving the health of the population by acting on nutrition, the Program focuses on primary prevention, screening and early treatment of conditions like heart disease, cancer, obesity, osteoporosis and diabetes. As an incentive program developed in keeping with the biopolitical views of the 1970s that saw education as an alternative means to hospitals for achieving good health, the Program is also a good public action tool for controlling costs.

To estimate cervical cytology coverage for the period 2008-2011 by age groups and health regions from data recorded in the medical records of women attending centers within the Catalan national health system. The data used to estimate coverage were obtained from the primary care information system. This information was anonymous and included age, center, date, and the results of cytological smears for a total of 2,292,564 women aged 15 years or more. A total of 758,690 smears were performed in 595,868 women. Among women aged 25-65 years, the estimated coverage was 32.4% of the assigned population and was 40.8% in the population attended. Geographical variation was observed, with higher coverage among health regions closer to Barcelona. Abnormal Pap smears increased slightly from 2008 to 2011 (from 3% to 3.5%, respectively, p <0.001). In women with a negative first smear, the mean interval until the second smear was 2.4 years, but only 50% of women with a negative first smear in 2008 attended a second round during the study period. Cervical screening coverage in the National Health Service of Catalonia includes one in three women. Second round participation was poor. Existing computer systems in primary care centers can ensure monitoring of population-based screening programs for cervical cancer. These systems could be used to plan an organized screening program to ensure wider coverage and better follow-up. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

The main objective of the project was the evaluation of the organizational and financial aspects of midwives in primary health care (PHC), functioning under The Population Program for the Early Detection of Cervical Cancer two years after the implementation of new law regulations, which enable this occupational group to collect cytological material for screening. Under this project, the data of the Program's Coordinating Centre, affecting midwives' postgraduate education in the field of pap smear tests, was taken into analysis. Furthermore, The National Health Fund (NFZ) reports on contracts entered in the field of the discussed topics, taking into consideration the value of health services performed within the Program in respect of ambulatory care and primary care units. NFZ concluded contracts for the provision of PHC service with 6124 service providers in 2016, including the contracts in the field of providing health services under the cervical cancer prevention program by PHC midwifes, which were entered into by 358 institutions (5.85%). The value of the basic services under the Program, carried out under NFZ contracts in 2014, amounted to approx. PLN 12.3 million, while the value of services performed by PHC midwives represented only 0.38% of this sum. The introduction of legislative changes, allowing PHC midwives to collect cytological material for screening, did not cause, in the period of the observation on a national scale, the expected growth of availability of basic stage services within the cervical cancer prevention program.

Globally, almost 40% of tuberculosis (TB) patients remain undiagnosed, and those that are diagnosed often experience prolonged delays before initiating correct treatment, leading to ongoing transmission. While there is a push for active case finding (ACF) to improve early detection and treatment of TB, there is extremely limited evidence about the relative cost-effectiveness of different ACF implementation models. Cambodia presents a unique opportunity for addressing this gap in evidence as ACF has been implemented using different models, but no comparisons have been conducted. The objective of our study is to contribute to knowledge and methodology on comparing cost-effectiveness of alternative ACF implementation models from the health service perspective, using programmatic data, in order to inform national policy and practice. We retrospectively compared three distinct ACF implementation models - door to door symptom screening in urban slums, checking contacts of TB patients, and door to door symptom screening focusing on rural populations aged above 55 - in terms of the number of new bacteriologically-positive pulmonary TB cases diagnosed and the cost of implementation assuming activities are conducted by the national TB program of Cambodia. We calculated the cost per additional case detected using the alternative ACF models. Our analysis, which is the first of its kind for TB, revealed that the ACF model based on door to door screening in poor urban areas of Phnom Penh was the most cost-effective (249 USD per case detected, 737 cases diagnosed), followed by the model based on testing contacts of TB patients (308 USD per case detected, 807 cases diagnosed), and symptomatic screening of older rural populations (316 USD per case detected, 397 cases diagnosed). Our study provides new evidence on the relative effectiveness and economics of three implementation models for enhanced TB case finding, in line with calls for data from 'routine conditions' to be included in disease control program strategic planning. Such cost-effectiveness comparisons are essential to inform resource allocation decisions of national policy makers in resource constraint settings. We applied a novel, pragmatic methodological approach, which was designed to provide results that are directly relevant to policy makers, costing the interventions from Cambodia's national TB program's perspective and using case finding data from implementation activities, rather than experimental settings.

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

Introduction. Cervical cancer is one of the most commonly diagnosed cancers among women in China. The World Health Organization (WHO) recommends routine screening for cervical cancer, and the WHO Global Monitoring Framework suggests that every nation monitors cervical cancer screening. However, little information is available on cervical cancer screening behavior among women in China. Methods. We used data from the 2010 China Chronic Disease and Risk Factor Surveillance System that included 51,989 women aged 18 years and older. We report the proportion of women who reported ever having had a Papanicolaou (Pap) test, stratified by sociodemographic characteristics and geographic region. Multivariable logistic regression modeling was performed to adjust for potential confounders. Results. Overall, 21% of 51,989 women reported having ever had a Pap test. The highest proportion was reported among women aged 30–39 years (30.1%, 95% confidence interval, 26.8%–33.4%). In all geographic regions, women in rural areas were consistently less likely than women in urban areas to report having had a Pap test. Among women who reported ever having a Pap test, 82% reported having the most recent test in the past 3 years. Factors associated with reporting ever having a test were being aged 30–49 years, higher education, being married, and having urban health insurance. Conclusion. Our results indicate that screening programs need to be strengthened along with a more intense focus on specific demographic groups. National cervical cancer screening guidelines and comprehensive implementation strategies are needed to make screening services available and accessible to all women. Implications for Practice: This study is the largest nationwide and population-based assessment of self-reported history of Pap test for cervical cancer screening in China. This article describes cervical cancer screening behavior among women and examines key demographic and geographic factors. Only one fifth of Chinese women reported having ever had a Pap test for cervical cancer screening. The results highlight the urgent need to develop national cervical cancer screening guidelines and strategies that make screening services widely available, accessible, and acceptable to all women, especially to those who reside in rural areas and those with no health insurance.

Recognition of the need to decrease cervical cancer rates in Indigenous populations has been ongoing-yet few successful interventions have been reported. In addition, literature addressing the challenges and barriers associated with designing screening programs aimed to specifically reach Indigenous women is limited. Here, we report findings from a mixed methods cervical cancer research project conducted in partnership with 10 First Nations communities in northwest Ontario, Canada. Individual interviews with community health professionals (the majority of whom identified as First Nations) stressed that awareness of cervical screening benefits is lacking. In contrast, focus group participants (women with no formal health education) emphasized the desire to learn more about the science of human papillomavirus (HPV), and that a positive HPV or abnormal Papanicolaou test need not mean a woman will undoubtedly develop cervical cancer. Both the health professionals and the focus group participants highlighted that sexual health education must start early, in schools, preferably before girls are sexually active and that it has to continue throughout life to create a screening culture with a focus on women's wellbeing. Both interview and focus group participants highlighted that sexual health education must start early, in schools, preferably before girls are sexually active and that it has to continue throughout life to create a screening culture with a focus on women's wellbeing. Health professionals elaborated mainly on special events for community women whereas focus group participants also recognized the need to include community men in health education particularly for de-stigmatizing the sexually-transmitted HPV infection.

One of the objectives of the National Institutes of Allergy and Infectious Diseases (NIAID) Biodefense Program is to identify or develop broad-spectrum antimicrobials for use against bioterrorism pathogens and emerging infectious agents. As a part of that program, our institution has screened the 10 000-compound MyriaScreen Diversity Collection of high-purity druglike compounds against three NIAID category A and one category B priority pathogens in an effort to identify potential compound classes for further drug development. The effective use of a Clinical and Laboratory Standards Institute-based high-throughput screening (HTS) 96-well-based format allowed for the identification of 49 compounds that had in vitro activity against all four pathogens with minimum inhibitory concentration values of ≤16 µg/mL. Adaptation of the HTS process was necessary to conduct the work in higher-level containment, in this case, biosafety level 3. Examination of chemical scaffolds shared by some of the 49 compounds and assessment of available chemical databases indicates that several may represent broad-spectrum antimicrobials whose activity is based on novel mechanisms of action.

To evaluate the impact and cost-effectiveness of introducing universal human papillomavirus (HPV) vaccination into the National Immunization Program (NIP) in Brazil. The Excel-based CERVIVAC decision support model was used to compare two strategies: (1) status quo (with current screening program) and (2) vaccination of a cohort of 11-year-old girls. National parameters for the epidemiology and costs of cervical cancer were estimated in depth. The estimates were based on data from the health information systems of the public health system, the PNAD 2008 national household survey, and relevant scientific literature on Brazil. Costs are expressed in 2008 United States dollars (US$), and a 5% discount rate is applied to both future costs and future health benefits. Introducing the HPV vaccine would reduce the burden of disease. The model estimated there would be 229 deaths avoided and 6677 disability-adjusted life years (DALYs) averted in the vaccinated cohort. The incremental cost-effectiveness ratios (ICERs) per DALY averted from the perspectives of the government (US$ 7663), health system (US$ 7412), and society (US$ 7298) would be considered cost-effective, according to the parameters adopted by the World Health Organization. In the sensitivity analysis, the ICERs were most sensitive to variations in discount rate, disease burden, vaccine efficacy, and proportion of cervical cancer caused by types 16 and 18. However, universal HPV vaccination remained a cost-effective strategy in most variations of the key estimates. Vaccine introduction could contribute additional benefits in controlling cervical cancer, but it requires large investments by the NIP. Among the essential conditions for attaining the expected favorable results are immunization program sustainability, equity in a population perspective, improvement of the screening program, and development of a surveillance system.

Background: Screening programs consistently underserve indigenous populations despite a higher overall burden of cancer. In this study, we explore the likely health gains and cost-effectiveness of a national colorectal cancer screening program for the indigenous Māori population of New Zealand (NZ). Methods: A Markov model estimated: health benefits (quality-adjusted life-year; QALY), costs, and cost-effectiveness of biennial immunochemical fecal occult blood testing (FOBTi) of 50- to 74-year-olds from 2011. Input parameters came from literature reviews, the NZ Bowel Screening Programme Pilot, and NZ linked health datasets. Equity analyses substituted non-Māori values for Māori values of background (noncolorectal cancer) morbidity and mortality, colorectal cancer survival and incidence, screening coverage, and stage-specific survival. We measured the change in "quality-adjusted life expectancy" (QALE) as a result of the intervention. Results: Based upon a threshold of GDP per capita (NZ$45,000), colorectal cancer screening in NZ using FOBTi is cost-effective: NZ$2,930 (US$1,970) per QALY gained [95% uncertainty interval: cost saving to $6,850 (US$4,610)]. Modeled health gains per capita for Māori were less than for non-Māori: half for 50- to 54-year-olds (0.031 QALYs per person for Māori vs. 0.058 for non-Māori), and a fifth (0.003 c.f. 0.016) for 70- to 74-year-olds and ethnic inequalities in QALE increased with colorectal cancer screening. Conclusions: Colorectal cancer screening in NZ using FOBTi is likely to be cost-effective but risks increasing inequalities in health for Māori. Impact: To avoid or mitigate the generation of further health inequalities, attention should be given to underserved population groups when planning and implementing screening programs.

The Biomolecular Screening Facility (BSF) is a multidisciplinary laboratory created in 2006 at the Ecole Polytechnique Federale de Lausanne (EPFL) to perform medium and high throughput screening in life sciences-related projects. The BSF was conceived and developed to meet the needs of a wide range of researchers, without privileging a particular biological discipline or therapeutic area. The facility has the necessary infrastructure, multidisciplinary expertise and flexibility to perform large screening programs using small interfering RNAs (siRNAs) and chemical collections in the areas of chemical biology, systems biology and drug discovery. In the framework of the National Centres of Competence in Research (NCCR) Chemical Biology, the BSF is hosting 'ACCESS', the Academic Chemical Screening Platform of Switzerland that provides the scientific community with chemical diversity, screening facilities and know-how in chemical genetics. In addition, the BSF started its own applied research axes that are driven by innovation in thematic areas related to preclinical drug discovery and discovery of bioactive probes.

Background and Objectives Nearly all babies in the United States are tested at birth for rare, serious, and treatable disorders through mandatory state newborn screening (NBS). Recently, there have been calls for an expanded, voluntary model to facilitate early diagnosis and treatment of a wider range of disorders. We applied the reasoned action framework to examine parental intentions to participate in voluntary expanded screening. Methods We recruited a national cohort of recent and expectant parents living in the U.S. who completed a self-administered online survey (N = 1,001). Using a mixed-level fractional factorial experiment, we studied parental participation intentions and preferences for timing of consent, cost, consent format, and testing options. Results We conducted a hierarchical regression analysis assessing parental intentions to participate in voluntary expanded NBS. Attitudes, perceived normative influence, and perceived behavioral control explained substantial variance in intention, with perceived normative influence emerging as the strongest predictor. We found no evidence that the manipulated program features altered mean levels of intention, but timing of parental permission, cost, and permission format moderated the relative importance of reasoned action constructs on intention. Conclusion Program design features may impact the psychological mechanisms underlying parental decision making for voluntary expanded screening. These results have important implications for parent education, outreach, and informed parental permission procedures. PMID:27526258

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.

Background: Historically, substance misuse has been a serious problem faced by worldwide military personnel. Some research showed that military personnel have higher rates of unhealthy substance use than their age peers in the general population. These problems have serious consequences and may lead to significant military difficulties in the field of readiness, discipline, and mental or physical health. In this review, we gathered various methods for prevention, diagnosis, and treatment of substance use disorders and suggested a comprehensive plan for Iran Armed Forces to improve existing services. Materials and Methods: This article is a narrative review study, which was carried out on 2016. A careful literature review was performed between January 1970 and April 2016 on several national and international databases. Articles were screened according to the following inclusion criteria: (1) review articles about prevention and treatment protocols, (2) executive guidance, (3) cohort articles about risk factors of addiction, and (4) randomized controlled trials about prevention or treatment of substance use disorders in army service members. After screening by title and abstract, 130 articles selected of 832 founded articles, and after quality assessment, finally, 63 articles included in the review. Results: There is a necessity to manage substance use disorder through prevention, screening, and then referral to proper services for diagnosis and treatment. Urinalysis programs for screening are cost-effective and should be considered as a main method. Effective treatment includes both behavioral and pharmacological methods. Conclusions: The ideal prevention program will include multiple and mutually reinforcing evidence-based universal, selective, and indicated attempts at both the individual and environmental levels. The implementation of screening and treatment strategies needs strict rules and national guideline for the comprehensive management of substance use disorders in army. PMID:28989915

OBJECTIVE TO BE ADDRESSED: The purpose of this study was to investigate the structural and organizational factors that contribute to the availability and increased capacity for substance abuse treatment programs in correctional settings. We used classification and regression tree statistical procedures to identify how multi-level data can explain the variability in availability and capacity of substance abuse treatment programs in jails and probation/parole offices. The data for this study combined the National Criminal Justice Treatment Practices (NCJTP) Survey and the 2000 Census. The NCJTP survey was a nationally representative sample of correctional administrators for jails and probation/parole agencies. The sample size included 295 substance abuse treatment programs that were classified according to the intensity of their services: high, medium, and low. The independent variables included jurisdictional-level structural variables, attributes of the correctional administrators, and program and service delivery characteristics of the correctional agency. The two most important variables in predicting the availability of all three types of services were stronger working relationships with other organizations and the adoption of a standardized substance abuse screening tool by correctional agencies. For high and medium intensive programs, the capacity increased when an organizational learning strategy was used by administrators and the organization used a substance abuse screening tool. Implications on advancing treatment practices in correctional settings are discussed, including further work to test theories on how to better understand access to intensive treatment services. This study presents the first phase of understanding capacity-related issues regarding treatment programs offered in correctional settings.

Technical problems of design and flight qualification of the proposed classes of surface insulation materials and leading edge materials were reviewed. A screening test plan, a preliminary design data test plan and a design data test plan were outlined. This program defined the apparent critical differences between the surface insulators and the leading edge materials, structuring specialized screening test plans for each of these two classes of materials. Unique testing techniques were shown to be important in evaluating the structural interaction aspects of the surface insulators and a separate task was defined to validate the test plan. In addition, a compilation was made of available information on proposed material (including metallic TPS), previous shuttle programs, pertinent test procedures, and other national programs of merit. This material was collected and summarized in an informally structured workbook.

REopt Screenings Catalyze Development of Hundreds of Megawatts of Renewable Energy for Federal Agencies

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

The U.S. Department of Energy's (DOE's) Federal Energy Management Program (FEMP) offers project assistance to federal agencies, which often begins with a desktop screening to develop a prioritized portfolio of renewable energy project opportunities. FEMP uses the National Renewable Energy Laboratory's (NREL) REopt energy planning platform to quickly and efficiently screen potential renewable energy opportunities at a single site or across a range of sites. REopt helps organizations prioritize the most economically and technically viable projects for further study, and identifies the size and mix of technologies that meet the organization's goals at minimum cost, along with the optimal operatingmore » strategies.« less

Screen for Life: National Colorectal Cancer Action Campaign (SFL) is a federally funded campaign to promote understanding of colorectal cancer and the importance of regular screening for adults aged 50 years and older. SFL uses a variety of communication strategies, including television public service announcements (PSAs). SFL materials are developed using the Health Communication Process endorsed by the U.S. Department of Health and Human Services, which has four stages: (a) planning and strategy development; (b) developing and pretesting concepts, messages, and materials; (c) implementing the program; and (d) assessing effectiveness and making refinements. This article describes SFL's application of this process to develop television PSAs in English and Spanish.

Oncology patient navigators help individuals overcome barriers to increase access to cancer screening, diagnosis, and timely treatment. This study, part of a randomized intervention trial investigating the efficacy of patient navigation in increasing colonoscopy completion, examined navigators' activities to ameliorate barriers to colonoscopy screening in a medically disadvantaged population. This study was conducted from 2012 through 2014 at Boston Medical Center. We analyzed navigator service delivery and survey data collected on 420 participants who were navigated for colonoscopy screening after randomization to this intervention. Key variables under investigation included barriers to colonoscopy, activities navigators undertook to reduce barriers, time navigators spent on each activity and per contact, and patient satisfaction with navigation services. Descriptive analysis assessed how navigators spent their time and examined what aspects of patient navigation were most valued by patients. Navigators spent the most time assessing patient barriers/needs; facilitating appointment scheduling; reminding patients of appointments; educating patients about colorectal cancer, the importance of screening, and the colonoscopy preparation and procedures; and arranging transportation. Navigators spent an average of 44 minutes per patient. Patients valued the navigators, especially for providing emotional/peer support and explaining screening procedures and bowel preparation clearly. Our findings help clarify the role of the navigator in colonoscopy screening within a medically disadvantaged community. These findings may help further refine the navigator role in cancer screening and treatment programs as facilities strive to effectively and efficiently integrate navigation into their services.

Objective: To estimate the cervical and breast cancer screening coverage and related factors among women aged 35-69 years who were in the National Cervical and Breast Screening Program, to provide evidence for improving cervical and breast cancer control and prevention strategy. Methods: Data used in this study were abstracted from the 2013 Chinese Chronic Diseases and Risk Factors Surveillance Program. A total of 66 130 women aged 35-64 years and 72 511 women aged 35-69 years were included for this study. Weighted prevalence, (with 95% confidence interval, CI ) was calculated for complex sampling design. Rao-Scott χ (2) method was used to compare the screening coverage among subgroups. A random intercept equation which involved the logit-link function, was fitted under the following five levels: provincial, county, township, village and individual. Fix effects of all explanatory variables were converted into OR with 95% CI . Results: In 2013, 26.7% (95% CI : 24.6%-28.9%) of the 35-64 year-old women reported that they ever had been screened for cervical cancer and 22.5% (95% CI : 20.4%-24.6%) of the 35-69 year-olds had ever undergone breast cancer screening. Lower coverage was observed among women residing in rural and central or western China than those in urban or eastern China ( P <0.000 1). The coverage among women aged 50 years or older was substantially lower than those aged 35-49 years. Those who were with low education level, unemployed, low household income and not covered by insurance, appeared fewer number on this cervical or breast cancer screening program ( P <0.000 1). Women living in rural and western China were having less chance of receiving the breast cancer screening ( P <0.05), but the difference was not statistically significant. Conclusion: It is essential to strengthen the community-based cervical and breast cancer screening programs, in order to increase the coverage. More attention should be paid to women aged 50 years or older, especially those socioeconomically disadvantaged ones.

Surface plasmons occur when the conduction electrons at a metal/dielectric interface resonantly interact with external electromagnetic fields. While surface plasmons in vicinity of a polaron in the dielectric material, a strong screening effect on polaron characteristics is introduced. In this work, we observed the reduction of polarons in multiferroic LuFe2O4, which is mainly contributed by surface plasmons.

Assessment of the efficacy of a hearing screening program for college students.

Taylor, Emily J; Emanuel, Diana C

2013-01-01

The Towson University (TU) Speech-Language-Hearing Center (SLHC) conducts annual hearing screenings for college students entering education or health-care professions. Hearing is screened in therapy rooms, and students who fail the screening are rescreened in a sound-treated booth. Students who fail the rescreening are referred for a comprehensive audiological assessment, which is offered at no cost to students at the SLHC. The purpose of this study was to examine the efficacy of the hearing screening program, to report trends in hearing screening statistics for the college student population, and to make recommendations regarding ways universities can optimize hearing screening programs. The study included retrospective and prospective portions. Hearing screening records were reviewed from 1999 to 2011. The prospective study involved recruiting students to participate in diagnostic testing following the hearing screening and measuring background noise levels in the therapy rooms. Hearing screening records from 1999 to 2011 were reviewed. In addition, during the three-day fall 2011 hearing screenings, 80 students were selected to participate in diagnostic testing. Data from the retrospective review were used to determine positive predictive value (PPV) between screening and rescreening. Return rates were also examined. For the prospective study, pure tone threshold results were compared to screening results to determine sensitivity, specificity, and PPV. The retrospective file review indicated that the hearing screening in the therapy room had poor PPV compared with the rescreening in the sound booth. Specifically, if a student failed the screening, they had only a 49% chance of failing the rescreening. This may have been due to background noise, as the prospective study found noise levels were higher than allowed by American National Standards Institute (ANSI) standard. Only a third of students referred for diagnostic testing from 1999 to 2010 returned for recommended diagnostic testing. For the prospective study, specificity and sensitivity were good when considering hearing loss present at the same frequencies as those screened (1000, 2000, 4000 Hz) but poor in comparison to hearing loss overall. The screening missed many students with a high frequency notch, which was most prevalent at 6000 Hz. The prevalence of a high frequency notch was 21 and 51%, using two different criteria for establishing the presence of a notch. If college hearing screenings are conducted in rooms that are not sound treated, poor PPV should be expected; thus, an immediate second stage rescreening for failures should be conducted in a sound booth. Hearing screenings limited to 1000, 2000, and 4000 Hz will miss many cases of hearing loss in the college-age population. College hearing screening program directors should carefully consider the purpose of the screening and adjust screening protocol, such as adding 6000 Hz and a question about noise exposure, in order to identify early signs of noise-induced hearing loss in college students. Programs should focus on ways to promote high return for follow-up rates. Estimates of prevalence of a high-frequency audiometric notch are highly dependent on the criteria used to define a notch.

Depression places a large economic burden on the US health care system. Routine screening has been recognized as a fundamental step in the effective treatment of depression, but should be undertaken only when support systems are available to ensure proper diagnosis, treatment, and follow-up. To estimate differences in prescribing new antidepressants and referral to stress management, psychotherapy, and other mental health (OMH) counseling at physician visits when documented depression screening was and was not performed. Cross-sectional physician visit data for adults from the 2005-2007 National Ambulatory Medical Care Survey were used. The final analytical sample included 55,143 visits, representing a national population estimate of 1,741,080,686 physician visits. Four dependent variables were considered: (1) order for new antidepressant(s), and referral to (2) stress management, (3) psycho therapy, or (4) OMH counseling. Bivariable and multivariable associations between depression screening and each measure of depression follow-up care were evaluated using the design-based F statistic and multivariable logistic regression models. New antidepressant prescribing increased significantly (2.12% of visits without depression screening vs 10.61% with depression screening resulted in a new prescription of an antidepressant). Referral to stress management was the behavioral treatment with the greatest absolute change (3.31% of visits without depression screening vs 33.10% of visits with depression screening resulted in a referral to stress management). After controlling for background sociodemographic characteristics, the adjusted odds ratio of a new antidepressant order remained significantly higher at visits involving depression screening (AOR 5.36; 99.9% CI 2.92-9.82), as did referrals for all behavioral health care services (ie, stress management, psychotherapy, and OMH counseling). At the national level, depression screening was associated with increased new antidepressant prescribing and referral for behavioral health care. It is critical for policy planners to recognize changes in follow-up depression care when implementing screening programs to ensure adequate capacity. Pharmacists are poised to assume a role in collaborative depression care, particularly with antidepressant medication therapy management.

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.

Similar to the healthcare systems in other industrialized countries, the Japanese healthcare system is facing the problem of increasing medical expenditure. In Japan, this situation may be primarily attributed to advanced technological developments, an aging population, and increasing patient demand. Japan also faces the problem of a declining youth population due to a low birth rate. Taken together, these problems present the healthcare system with a very difficult financial situation. Several reforms have been undertaken to contain medical expenditure, such as increasing employee copayment for health insurance from 10% to 20% in 1997 and from 20% to 30% in 2003 in order to curb unnecessary visits to medical institutions. Since the aging of the Japanese population is inevitable, a suitable method to contain medical expenditure may be to screen individuals who are likely to develop lifestyle-related diseases and conduct early intervention programs for them to prevent the development of diseases such as myocardial infarction or stroke that are costly to treat. If this goal is attained, it may contribute to the containment of medical expenditure as well as to improving the quality of life of the elderly. Therefore, the Japanese Ministry of Health, Labor and Welfare has decided to introduce a nationwide health screening and intervention program specifically targeting the metabolic syndrome commencing April 2008. Here, we discuss (1) the background of the Japanese healthcare system and the problems facing it, (2) the underlying objective and details of the new screening program, and (3) the expected impact of the program.

Abstract Introduction: Arginine is an essential amino acid that plays an important role in various body functions including cell division, wound healing, removal of ammonia, immune function, and release of hormones. Hyperargininemia, an autosomal recessive genetic disorder, is considered one of the least common urea cycle disorders. It rarely presents in the neonatal period but rather appears in children at the age between 2 and 4 years. Case Presentation: Herein, we demonstrate a case of a 14-year-old female who presented to the neurology clinic with several neurological complications, which were found to be a consequence of high levels of arginine discovered after performing a metabolic screening test. The hyperargininemia was because of a point mutation of A1 gene on 6q23 resulting in deficiency in arginase enzyme. The complications of this lately diagnosed case of hyperargininemia would have been avoided if a newborn screen were done as a part of a national program. Conclusion: This study presented certain neurological complications in a 14-year-old female who was lately diagnosed with hyperargininemia. Out case report strongly emphasizes the importance of establishing a national neonatal screening policy to ensure early detection of inherited metabolic disorders, in particular those which can be easily treated, in the Kingdom of Bahrain.

The accumulation of national epidemiological data since the late 1990s has led to the adoption of evidence-based guidelines for breast cancer screening in Lebanon (2006). Almost 50% of breast cancer patients in Lebanon are below the age of 50 years and the age-adjusted incidence rate is estimated at 69 new cases per 100,000 per year (2004). This official notification calls for breast self-examination (BSE) every month starting age 20, and a clinical breast examination (CBE) performed by a physician every three years between the ages of 20 and 40 years. Starting age 40, and for as long as a woman is in good health, an annual CBE and mammography are recommended. Women with known genetic family history of breast cancer should start screening 10 years earlier than the first young patient in the family, or earlier depending on medical advice. The Breast Cancer National Task Force (BCNTF) recommends certification of mammography centers and continued training of personnel to assure high quality mammograms, and to minimize unnecessary investigations and surgeries.It recommends that a national program should record call-backs of women for annual screening and follow-up data on abnormal mammograms. BCNTF encourages the adoption of these guidelines and monitoring of their results, as well as follow-up of breast cancer epidemiology and registry in Lebanon, and scientific progress in early breast cancer detection to determine needs for modifications in the future.

Interpreting screening mammography accurately is challenging and requires ongoing education to maintain and improve interpretative skills. Recognizing this, many countries with organized breast screening programs have developed audit and feedback systems using national performance data to help radiologists assess and improve their skills. We developed and tested an interactive Website to provide screening and diagnostic mammography audit feedback with comparisons to national and regional benchmarks. Radiologists who participate in three Breast Cancer Surveillance Consortium registries in the United States were invited during 2009 and 2010 to use a Website that provides tabular and graphical displays of mammography audit reports with comparisons to national and regional performance measures. We collected data about the use and perceptions of the Website. Thirty-five of 111 invited radiologists used the Website from one to five times in a year. The most popular measure was sensitivity for both screening and diagnostic mammography, whereas a table with all measures was the most visited page. Of the 13 radiologists who completed the postuse survey, all found the Website easy to use and navigate, 11 found the benchmarks useful, and nine reported that they intended to improve a specific outcome measure that year. An interactive Website to provide customized mammography audit feedback reports to radiologists has the potential to be a powerful tool in improving interpretive performance. The conceptual framework of customized audit feedback reports can also be generalized to other imaging tests.

Background The integration of mental and neurologic services in healthcare is a global priority. The universal Social Security of Costa Rica aspires to develop national screening of neurodegenerative disorders among the elderly, as part of the non-communicable disease agenda. Objective This study assessed the feasibility of routine screening for Parkinson's disease (PD) and Alzheimer's disease (AD) within the public healthcare system of Costa Rica. Design The population (aged ≥65) in the catchment areas of two primary healthcare clinics was targeted for motor and cognitive screening during routine annual health check-ups. The screening followed a tiered three-step approach, with increasing specificity. Step 1 involved a two-symptom questionnaire (tremor-at-rest; balance) and a spiral drawing test for motor assessment, as well as a three-word recall and animal category fluency test for cognitive assessment. Step 2 (for those failing Step 1) was a 10-item version of the Unified Parkinson Disease Rating Scale and the Mini-Mental State Examination. Step 3 (for those failing Step 2) was a comprehensive neurologic exam with definitive diagnosis of PD, AD, mild cognitive impairment (MCI), other disorders, or subjects who were healthy. Screening parameters and disease prevalence were calculated. Results Of the 401 screened subjects (80% of target population), 370 (92%), 163 (45%), and 81 (56%) failed in Step 1, Step 2, and Step 3, respectively. Thirty-three, 20, and 35 patients were diagnosed with PD, AD, and MCI, respectively (7 were PD with MCI/AD); 90% were new cases. Step 1 sensitivities of motor and cognitive assessments regarding Step 2 were both 93%, and Step 2 sensitivities regarding definitive diagnosis 100 and 96%, respectively. Specificities for Step 1 motor and cognitive tests were low (23% and 29%, respectively) and for Step 2 tests acceptable (76%, 94%). Based on international data, PD prevalence was 3.7 times higher than expected; AD prevalence was as expected. Conclusion Proposed protocol adjustments will increase test specificity and reduce administration time. A routine screening program is feasible within the public healthcare system of Costa Rica.

CASPer, an online pre-interview screen for personal/professional characteristics: prediction of national licensure scores.

Typically, only a minority of applicants to health professional training are invited to interview. However, pre-interview measures of cognitive skills predict for national licensure scores (Gauer et al. in Med Educ Online 21 2016) and subsequently licensure scores predict for performance in practice (Tamblyn et al. in JAMA 288(23): 3019-3026, 2002; Tamblyn et al. in JAMA 298(9):993-1001, 2007). Assessment of personal and professional characteristics, with the same psychometric rigour of measures of cognitive abilities, are needed upstream in the selection to health profession training programs. To fill that need, Computer-based Assessment for Sampling Personal characteristics (CASPer)-an on-line, video-based screening test-was created. In this paper, we examine the correlation between CASPer and Canadian national licensure examination outcomes in 109 doctors who took CASPer at the time of selection to medical school. Specifically, CASPer scores were correlated against performance on cognitive and 'non-cognitive' subsections of both the Medical Council of Canada Qualifying Examination (MCCQE) Parts I (end of medical school) and Part II (18 months into specialty training). Unlike most national licensure exams, MCCQE has specific subcomponents examining personal/professional qualities, providing a unique opportunity for comparison. The results demonstrated moderate predictive validity of CASPer to national licensure outcomes of personal/professional characteristics three to six years after admission to medical school. These types of disattenuated correlations (r = 0.3-0.5) are not otherwise predicted by traditional screening measures. These data support the ability of a computer-based strategy to screen applicants in a feasible, reliable test, which has now demonstrated predictive validity, lending evidence of its validation for medical school applicant selection.

Lung cancer risk prediction models have the potential to make programs more affordable; however, the economic evidence is limited. Participants in the National Lung Cancer Screening Trial (NLST) were retrospectively identified with the risk prediction tool developed from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. The high-risk subgroup was assessed for lung cancer incidence and demographic characteristics compared with those in the low-risk subgroup and the Pan-Canadian Early Detection of Lung Cancer Study (PanCan), which is an observational study that was high-risk-selected in Canada. A comparison of high-risk screening versus standard care was made with a decision-analytic model using data from the NLST with Canadian cost data from screening and treatment in the PanCan study. Probabilistic and deterministic sensitivity analyses were undertaken to assess uncertainty and identify drivers of program efficiency. Use of the risk prediction tool developed from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial with a threshold set at 2% over 6 years would have reduced the number of individuals who needed to be screened in the NLST by 81%. High-risk screening participants in the NLST had more adverse demographic characteristics than their counterparts in the PanCan study. High-risk screening would cost $20,724 (in 2015 Canadian dollars) per quality-adjusted life-year gained and would be considered cost-effective at a willingness-to-pay threshold of $100,000 in Canadian dollars per quality-adjusted life-year gained with a probability of 0.62. Cost-effectiveness was driven primarily by non-lung cancer outcomes. Higher noncurative drug costs or current costs for immunotherapy and targeted therapies in the United States would render lung cancer screening a cost-saving intervention. Non-lung cancer outcomes drive screening efficiency in diverse, tobacco-exposed populations. Use of risk selection can reduce the budget impact, and screening may even offer cost savings if noncurative treatment costs continue to rise. Crown Copyright © 2017. Published by Elsevier Inc.

Since 2006, the Peruvian National TB program (NTP) recommends voluntary counseling and testing (VCT) for all tuberculosis (TB) patients. Responding to the differential burden of both diseases in Peru, TB is managed in peripheral health facilities while HIV is managed in referral centers. This study aims to determine the coverage of HIV screening among TB patients and the characteristics of persons not screened. From March 2010 to December 2011 we enrolled new smear-positive pulmonary TB adults in 34 health facilities in a district in Lima. NTP staff offered VCT to all TB patients. Patients with an HIV positive result were referred for confirmation tests and management. We interviewed patients to collect their demographic and clinical characteristics and registered if patients opted in or out of the screening. Of the 1295 enrolled TB patients, nine had a known HIV diagnosis. Of the remaining, 76.1% (979) were screened for HIV. Among the 23.9% (307) not screened, 38.4% (118) opted out of the screening. TB patients at one of the health care facilities of the higher areas of the district (OR = 3.38, CI 95% 2.17-5.28 for the highest area and OR = 2.82, CI 95% 1.78-4.49 for the high area) as well as those reporting illegal drug consumption (OR = 1.65, CI 95% 1.15-2.37) were more likely not to be screened. Twenty-four were HIV positive (1.9% of all patients 1295, or 2.4% of those screened). Of 15 patients diagnosed with HIV during the TB episode, ten were enrolled in an HIV program. The median time between the result of the HIV screening and the first consultation at the HIV program was 82 days (IQR, 32-414). The median time between the result of the HIV screening and antiretroviral initiation was 148.5 days (IQR 32-500). An acceptable proportion of TB patients were screened for HIV in Lima. Referral systems of HIV positive patients should be strengthened for timely ART initiation.

Breast and cervical cancer screening rates remain low among immigrant women and those of low socioeconomic status. The Cancer Awareness: Ready for Education and Screening (CARES) project ran a peer-led multi-lingual educational program between 2012 and 2014 to reach under and never-screened women in Central Toronto, where breast and cervical cancer screening rates remain low. The objective of this qualitative study was to better understand how Chinese and South Asian immigrants - the largest and most under-screened immigrant groups according to national and provincial statistics - conceive of breast and cervical cancer screening. We explored their experiences with screening to date. We explicitly inquired about their perceptions of the health care system, their screening experiences with family physicians and strategies that would support screening in their communities. We conducted 22 individual interviews and two focus groups in Bengali and Mandarin with participants who had attended CARES educational sessions. Transcripts were coded through an iterative constant comparative and interpretative approach. Themes fell into five major, overlapping domains: risk perception and concepts of preventative health and screening; health system engagement and the embedded experience with screening; fear of cancer and procedural pain; self-efficacy, obligation, and willingness to be screened; newcomer barriers and competing priorities. These domains all overlap, and contribute to screening behaviours. Immigrant women experienced a number of barriers to screening related to 'navigating newness', including transportation, language barriers, arrangements for time off work and childcare. Fear of screening and fear of cancer took many forms; painful or traumatic encounters with screening were described. Female gender of the provider was paramount for both groups. Newly screened South Asian women were reassured by their first encounter with screening. Some Chinese women preferred the anonymous screening options available in China. Women generally endorsed a willingness to be screened, and even offered to organize women in their community hubs to access screening. The experience of South Asian and Chinese immigrant women suggests that under and never-screened newcomers may be effectively integrated into screening programs through existing primary care networks, cultural-group specific outreach, and expanding access to convenient community -based screening.

One of 5 nationally funded Centers for Disease Control and Prevention Colorectal Cancer (CRC) Screening Demonstration Programs, Project SCOPE, was conducted at an academic medical center and provided colonoscopy screening at no cost to underserved minority patients from local community health centers. Established barriers to CRC screening (eg, financial, language, transportation) among the target population were addressed through clinical coordination of care by key project staff. The use of a clinician with a patient navigator allowed for the performance of precolonoscopy "telephone visits" instead of office visits to the gastroenterologist in virtually all patients. The clinician elicited information relevant to making screening decisions (eg, past medical and surgical history, focused review of systems, medication/supplement use, CRC screening history). The patient navigator reduced barriers, including, but not limited to, scheduling, transportation, and physical navigation of the medical center on the day of colonoscopy. Preprogram preparation was vital in laying groundwork for the project, yet enhancements to the program were ongoing throughout the screening period. Detailed referral forms from primary care physicians, coupled with information obtained during telephone interviews, facilitated high colonoscopy completion rates and excellent patient satisfaction. Similarly valuable was the employment of a bilingual patient navigator, who provided practical and emotional patient support. Academic medical centers can be efficient models for providing CRC screening to disadvantaged populations. Coordination of care by a preventive medicine department, directing the recruitment, scheduling, prescreening education, and the evaluation and preparation of target populations had an overall positive effect on CRC screening with colonoscopy among patients from a community health center. © 2013 American Cancer Society.

Price, Sarah Kye; Coles, D Crystal; Wingold, Tracey

2017-11-01

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.

Unsupervised self-testing as part public health screening for HIV in resource-poor environments: some ethical considerations.

PubMed

Scott, P Anne

2014-07-01

The use of unsupervised self-testing as part of a national screening program for HIV infection in resource-poor environments with high HIV prevalence may have a number of attractive aspects, such as increasing access to services for hard to reach and isolated populations. However, the presence of such technologies is at a relatively early stage in terms of use and impact in the field. In this paper, a principle-based approach, that recognizes the fundamentally utilitarian nature of public health combined with a focus on autonomy, is used as a lens to explore some of the ethical issues raised by HIV self-testing. The conclusion reached in this review is that at this point in time, on the basis of the principles of utility and respect for autonomy, it is not ethically appropriate to incorporate unsupervised HIV self-testing as part of a public health screening program in resource-poor environments.

Objective To provide background information for strengthening cervical cancer prevention in the Pacific by mapping current human papillomavirus (HPV) vaccination and cervical cancer screening practices, as well as intent and barriers to the introduction and maintenance of national HPV vaccination programmes in the region. Materials and Methods A cross-sectional questionnaire-based survey among ministry of health officials from 21 Pacific Island countries and territories (n=21). Results Cervical cancer prevention was rated as highly important, but implementation of prevention programs were insufficient, with only two of 21 countries and territories having achieved coverage of cervical cancer screening above 40%. Ten of 21 countries and territories had included HPV vaccination in their immunization schedule, but only two countries reported coverage of HPV vaccination above 60% among the targeted population. Key barriers to the introduction and continuation of HPV vaccination were reported to be: (i) Lack of sustainable financing for HPV vaccine programs; (ii) Lack of visible government endorsement; (iii) Critical public perception of the value and safety of the HPV vaccine; and (iv) Lack of clear guidelines and policies for HPV vaccination. Conclusion Current practices to prevent cervical cancer in the Pacific Region do not match the high burden of disease from cervical cancer. A regional approach, including reducing vaccine prices by bulk purchase of vaccine, technical support for implementation of prevention programs, operational research and advocacy could strengthen political momentum for cervical cancer prevention and avoid risking the lives of many women in the Pacific.

The Community Preventive Services Task Force recommends combined diet and physical activity promotion programs for people at increased risk of type 2 diabetes, as evidence continues to show that intensive lifestyle interventions are effective for overweight individuals with prediabetes. To illustrate the potential clinical and economic benefits of treating prediabetes with lifestyle intervention to prevent or delay onset of type 2 diabetes and sequelae. This 2014 analysis used a Markov model to simulate disease onset, medical expenditures, economic outcomes, mortality, and quality of life for a nationally representative sample with prediabetes from the 2003-2010 National Health and Nutrition Examination Survey. Modeled scenarios used 10-year follow-up results from the lifestyle arm of the Diabetes Prevention Program and Outcomes Study versus simulated natural history of disease. Over 10 years, estimated average cumulative gross economic benefits of treating patients who met diabetes screening criteria recommended by the ADA ($26,800) or USPSTF ($24,700) exceeded average benefits from treating the entire prediabetes population ($17,800). Estimated cumulative, gross medical savings for these three populations averaged $10,400, $11,200, and $6,300, respectively. Published estimates suggest that opportunistic screening for prediabetes is inexpensive, and lifestyle intervention similar to the Diabetes Prevention Program can be achieved for ≤$2,300 over 10 years. Lifestyle intervention among people with prediabetes produces long-term societal benefits that exceed anticipated intervention costs, especially among prediabetes patients that meet the ADA and USPSTF screening guidelines.

Computational Toxicology at the US EPA | Science Inventory ...

EPA Pesticide Factsheets

Computational toxicology is the application of mathematical and computer models to help assess chemical hazards and risks to human health and the environment. Supported by advances in informatics, high-throughput screening (HTS) technologies, and systems biology, EPA is developing robust and flexible computational tools that can be applied to the thousands of chemicals in commerce, and contaminant mixtures found in America’s air, water, and hazardous-waste sites. The ORD Computational Toxicology Research Program (CTRP) is composed of three main elements. The largest component is the National Center for Computational Toxicology (NCCT), which was established in 2005 to coordinate research on chemical screening and prioritization, informatics, and systems modeling. The second element consists of related activities in the National Health and Environmental Effects Research Laboratory (NHEERL) and the National Exposure Research Laboratory (NERL). The third and final component consists of academic centers working on various aspects of computational toxicology and funded by the EPA Science to Achieve Results (STAR) program. Key intramural projects of the CTRP include digitizing legacy toxicity testing information toxicity reference database (ToxRefDB), predicting toxicity (ToxCast™) and exposure (ExpoCast™), and creating virtual liver (v-Liver™) and virtual embryo (v-Embryo™) systems models. The models and underlying data are being made publicly available t

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.

This study was to evaluate the effect of additional brief counseling by a primary care physician on lifestyle modification of examinees after a periodic health examination. 1,000 participants of the 2007 Korean national health screening program were asked to note any variation in their health behavior after participating in the screening program. The degree of comprehensive motivation for lifestyle modification was assessed in terms of stages of health behavior change. We calculated odds ratio of positive change (enhanced stage of change) with multiple logistic regression analysis and age-adjusted proportion of positive changers. Of 989 respondents, 486 and 503 received the basic and additional programs, respectively. Additional group were more likely to be positive changer than basic group (adjusted OR 1.78; 95% CI 1.19-2.65), and this was more prominent in older age group (adjusted OR 2.38, 95% CI 1.23-4.58). The age-adjusted proportions of positive changers were 22.7% (95% CI, 17.9-28.3) and 36.2% (95% CI, 30.4-42.4) in the basic and additional groups, respectively (P < 0.001). The additional consultation led to improvements in the stage of health behavior change after the health examination. Thus, such a consultation should be considered when designing a health-screening program.

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.

In the Netherlands, a non-selective opt-out instead of a selective opt-in antenatal HIV screening strategy was implemented in 2004. In case of infection, screening was followed by prevention of mother-to-child-transmission (PMTCT). We compared the performance of the two strategies in terms of detection of new cases of HIV and vertical transmission. HIV-infected pregnant women were identified retrospectively from the Dutch HIV cohort ATHENA January 2000 to January 2008. Apart from demographic, virological and immunological data, the date of HIV infection in relation to the index pregnancy was established. Separately, all infants diagnosed with HIV born following implementation of the screening program were identified by a questionnaire via the paediatric HIV centres. 162/481 (33.7%) HIV-positive pregnant women were diagnosed with HIV before 2004 and 172/214 (80.3%) after January 2004. Multivariate analysis showed an 8-fold (95% confidence interval 5.47-11.87) increase in the odds of HIV detection during pregnancy after the national introduction of the opt-out strategy. Still, three children born during a 5-year period after July 2004 were infected due to de novo infection in pregnancy. Implementation of a nation-wide screening strategy based upon non-selective opt-out screening followed by effective PMTCT appeared to detect more HIV-infected women for the first time in pregnancy and to reduce vertical transmission of HIV substantially. Nonetheless, still few children are infected because of maternal infection after the first trimester. We propose the introduction of partner screening on HIV as part of the antenatal screening strategy.

To determine the cost-effectiveness of implementing a point-of-care (POC) Lactate Program in the emergency department (ED) for patients with suspected sepsis to identify patients who can benefit from early resuscitation. We constructed a cost-effectiveness model to examine an ED with 30 000 patients annually. We evaluated a POC lactate program screening patients with suspected sepsis for an elevated lactate ≥4 mmol/L. Those with elevated lactate levels are resuscitated and their lactate clearance is evaluated by serial POC lactate measurements. The POC Lactate Program was compared with a Usual Care Strategy in which all patients with sepsis and an elevated lactate are admitted to the intensive care unit. Costs were estimated from the 2014 Medicare Inpatient and National Physician Fee schedules, and hospital and industry estimates. In the base-case, the POC Lactate Program cost $39.53/patient whereas the Usual Care Strategy cost $33.20/patient. The screened patients in the POC arm resulted in 1.07 quality-adjusted life years for an incremental cost-effectiveness ratio of $31 590 per quality-adjusted life year gained, well below accepted willingness-to-pay-thresholds. Implementing a POC Lactate Program for screening ED patients with suspected sepsis is a cost-effective intervention to identify patients responsive to early resuscitation.

To evaluate the feasibility of a mobile screening service model for abdominal aortic aneurysm (AAA) in a remote population centre in Australia. Screening test evaluation. A remote regional centre (population: 20 000) in far western NSW. Men aged 65-74 years, identified from the Australian Electoral roll. A mobile screening service using directed ultrasonography, a basic health check and post-screening consultation. Attendance at the screening program, occurrence of AAA in the target population and effectiveness of screening processes. A total of 516 men without a previous diagnosis of AAA were screened, an estimated response rate of 60%. Of these, 463 (89.7%) had a normal aortic diameter, 28 (5.4%) ectatic and 25 (4.9%) a small, moderate or significant aneurysm. Two men with AAA were recommended for surgery. Feedback from participants indicated that the use of a personalised letter of invitation helped with recruitment, that the screening process was acceptable and the service valued. It is feasible to organise and operate a mobile AAA screening service from moderate sized rural and remote population centres. This model could be scaled up to provide national coverage for rural and remote residents.

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides cancer screening to low-income, un-, and underinsured women through more than 11 000 primary care clinics. The program is well-positioned to work with health systems to implement evidence-based interventions (EBIs) to increase screening among all women. To collect baseline data on EBI use, evaluation of EBIs, and related training needs among NBCCEDP grantees. The Centers for Disease Control and Prevention conducted a Web-based survey in late 2013 among NBCCEDP grantees for the period July 2012 to June 2013. This was the first systematic assessment of EBIs among NBCCEDP grantees. The Centers for Disease Control and Prevention's NBCCEDP. Primarily program directors/coordinators for all 67 NBCCEDP grantees. Data captured were used to assess implementation of 5 EBIs, their evaluation, and related training needs. Frequencies and proportions were determined. Cluster analysis identified grantees with similar patterns of EBI use for NBCCEDP clients and providers. On average, 4.1 of 5 EBIs were implemented per grantee for NBCCEDP clients and providers. Four clusters were identified including "high overall EBI users," "high provider EBI users," "high EBI users with no provider assessment and feedback," and "high client EBI users." Only 1.8 EBIs were implemented, on average, with non-NBCCEDP clients and providers. Fewer than half (n = 32, 47.8%) of grantees conducted process or outcome evaluation of 1 or more EBIs. Overall, 47.6% of grantees reported high or medium training needs for client-oriented EBIs and 54.3% for provider-oriented EBIs. The NBCCEDP grantees are implementing EBIs extensively with clients and providers. Increased EBI use among non-NBCCEDP clients/providers is needed to extend the NBCCEDP's reach and impact. Grantee training and technical assistance is necessary across EBIs. In addition, grantees' use of process and outcome evaluation of EBI implementation must be increased to inform effective program implementation.

Newborn screening by tandem mass spectrometry: ethical and social issues.

Emerging technologies like Tandem Mass Spectrometry (TMS) enable multiple tests on a single blood sample and allow the expansion of Newborn Screening (NBS) to include various metabolic diseases. Introducing TMS for NBS raises important social and ethical questions: what are the criteria for adding disorders to screening panels? What evidence justifies expansion of screening? How can equity in NBS access and standards be ensured? How can policy standards be set, given the multiplicity of stakeholders? To address emerging issues, policy-makers, patient advocates, clinicians and researchers had a workshop during the 2005 Garrod Symposium. The participants received a summary of the discussion and understood the workshop's goal was to provide a basis for further discussion. This article contributes to this ongoing discussion. Several proposed recommendations assert the centrality of including social and ethical issues in the assessment of whether or not to introduce TMS. The article outlines five key recommendations for advancing the NBS agenda: national public health leadership; transparency; increased national consistency in NBS strategy, including minimum standards; collaboration between the federal and provincial/territorial governments and diverse stakeholders; and supporting research and/or programs based on effectiveness, which integrate ethical and social issues into assessment.

Controversies regarding the benefits of breast cancer screening programs have led to the promotion of new strategies taking into account individual preferences, such as decision aid. The aim of this study was to assess the impact of a decision aid leaflet on the participation of women invited to participate in a national breast cancer screening program. This Randomized, multicentre, controlled trial. Women aged 50 to 74 years, were randomly assigned to receive either a decision aid or the usual invitation letter. Primary outcome was the participation rate 12 months after the invitation. 16 000 women were randomized and 15 844 included in the modified intention-to-treat analysis. The participation rate in the intervention group was 40.25% (3174/7885 women) compared with 42.13% (3353/7959) in the control group (p = 0.02). Previous attendance for screening (RR = 6.24; [95%IC: 5.75-6.77]; p < 0.0001) and medium household income (RR = 1.05; [95%IC: 1.01-1.09]; p = 0.0074) were independently associated with attendance for screening. This large-scale study demonstrates that the decision aid reduced the participation rate. The decision aid activate the decision making process of women toward non-attendance to screening. These results show the importance of promoting informed patient choices, especially when those choices cannot be anticipated. PMID:26883201

Recently, a national breast cancer screening program has been introduced in Iran.The aim of this study was to examine the determinants of breast cancer screening uptake among Kurdish women, in order to identify those characteristics that may be potentially associated with the screening uptake. Through a cross sectional study, in 2014, a random sample of 561 women aged 40 years and older without the history of breast cancer and identified with Kurdish background in Baneh county, Iran, were recruited and interviewed by two trained interviewers. Data were collected using a valid and reliable researcher made questionnaire. Univariate and multivariate logistic regression models with self-reported screening history as the dependent variable were used to estimate the odds ratios (ORs) with 95% of CI. The mean age of women was 43.64 (SD = 5.17). The participation rate in the mammography program was 16.8% (95% CI: 13.7-19.8%). The lowest level of participation was found among women aged 60 and older (OR = 0.30, 95% CI: 0.14-0.69), illiterate (OR = 0.63,95% CI: 0.40-0.99) and post-menopausal (OR = 0.56, 95% CI: 0.35-0.91) women. It was found that the level of breast screening uptake was low among Kurdish women compared to those reported in the previous studies. Designing participation enhancing interventions with a specific focus on older, illiterate and post-menopausal women are recommended.

The objective was to determine whether obesity screening and weight management program participation and outcomes are equitable for individuals with serious mental illness (SMI) and depressive disorder (DD) compared to those without SMI/DD in Veterans Health Administration (VHA), the largest integrated US health system, which requires obesity screening and offers weight management to all in need. We used chart-reviewed, clinical and administrative VHA data from fiscal years 2010-2012 to estimate obesity screening and participation in the VHA's weight management program (MOVE!) across groups. Six- and 12-month weight changes in MOVE! participants were estimated using linear mixed models adjusted for confounders. Compared to individuals without SMI/DD, individuals with SMI or DD were less frequently screened for obesity (94%-94.7% vs. 95.7%) but had greater participation in MOVE! (10.1%-10.4% vs. 7.4%). MOVE! participants with SMI or DD lost approximately 1 lb less at 6 months. At 12 months, average weight loss for individuals with SMI or neither SMI/DD was comparable (-3.5 and -3.3 lb, respectively), but individuals with DD lost less weight (mean=-2.7 lb). Disparities in obesity screening and treatment outcomes across mental health diagnosis groups were modest. However, participation in MOVE! was low for every group, which limits population impact.

To identify the overlapping and unique health and safety needs and concerns identified by early care and education (ECE) directors, health records, and observed compliance with national health and safety (NHS) standards. Cross-sectional study. 127 ECE programs from 5 California counties participated in the study, including 118 directors and 2,498 children's health records. Qualitative data were collected using standardized ECE directors' interviews to identify their health and safety concerns; and objective, quantitative data were collected using child health record reviews to assess regular health care, immunizations, health insurance, special health care needs, and screening tests and an observation Checklist of 66 key NHS standards collected by research assistants. The overlapping health and safety needs and concerns identified by the directors and through observations were hygiene and handwashing, sanitation and disinfection, supervision, and the safety of indoor and outdoor equipment. Some of the health and safety needs identified by only one assessment method were health and safety staff training, medical plans for children with special health care needs and follow-up on positive screening tests. Comprehensive, multimethod assessments are useful to identify health and safety needs and develop public health nursing interventions for ECE programs.

California has several health insurance programs for children. However, the system for enrolling into these programs is complex and difficult to manage for many families. Express Lane Eligibility is designed to streamline the Medicaid (called Medi-Cal in California) enrollment process by linking it to the National School Lunch Program. If a child is eligible for free lunch and the parents consent, the program provides two months of presumptive eligibility for Medi-Cal and a simplified application process for continuation in Medi-Cal. For those who are ineligible, it provides a referral to other programs. An evaluation of Express Lane shows that while many children were presumptively enrolled, nearly half of the applicants were already enrolled in Medi-Cal. Many Express Enrolled children failed to complete the full Medi-Cal enrollment process. Few were referred to the State Children's Health Insurance Program or county programs. Express Lane is less useful as a broad screening strategy, but can be one of many tools that communities use to enroll children in health insurance.

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.

In 2014, a national colorectal cancer (CRC) screening program was launched in the Netherlands. It is difficult to assess for the individual CRC patient whether the oncological benefits of surgery will outweigh the morbidity of the procedure, especially in early lesions. This study compares patient and tumour characteristics between screen-detected and non-screen-detected patients. Secondly, we present an overview of treatment options and clinical dilemmas when treating patients with early stage colorectal disease. Between January 2014 and December 2016, all patients with non-malignant polyps or CRC who were referred to the Department of Surgery of the Leiden University Medical Centre in the Netherlands were included. Baseline characteristics, type of treatment and short-term outcomes of patients with screen-detected and non-screen-detected colorectal tumours were compared. A total of 426 patients were included, of whom 240 (56.3%) were identified by screening. Non-screen-detected patients more often had comorbidity (p=0.03), the primary tumour was more often located in the rectum (p=0.001) and there was a higher rate of metastatic disease (p<0.001). Among 354 surgically treated patients, postoperative adverse events did not significantly differ between the two groups (p=0.38). Of 46 patients with T1 CRC in the endoscopic resection specimen, 23 underwent surgical resection of which only 30.4% had residual invasive disease at colectomy. Despite differences in comorbidity and stage, surgical outcome of patients with screen-detected tumours compared to non-screen-detected tumours was not significantly different. Considering its limited oncological benefits as well as the rate of adverse events, surgery for non-malignant polyps and T1 CRC should be considered carefully. This article is protected by copyright.

To determine the incremental cost-effectiveness of a new telemedicine technician-based assessment relative to an existing model of family physician (FP)-based assessment of diabetic retinopathy (DR) in Singapore from the health system and societal perspectives. Model-based, cost-effectiveness analysis of the Singapore Integrated Diabetic Retinopathy Program (SiDRP). A hypothetical cohort of patients aged 55 years with type 2 diabetes previously not screened for DR. The SiDRP is a new telemedicine-based DR screening program using trained technicians to assess retinal photographs. We compared the cost-effectiveness of SiDRP with the existing model in which FPs assess photographs. We developed a hybrid decision tree/Markov model to simulate the costs, effectiveness, and incremental cost-effectiveness ratio (ICER) of SiDRP relative to FP-based DR screening over a lifetime horizon. We estimated the costs from the health system and societal perspectives. Effectiveness was measured in terms of quality-adjusted life-years (QALYs). Result robustness was calculated using deterministic and probabilistic sensitivity analyses. The ICER. From the societal perspective that takes into account all costs and effects, the telemedicine-based DR screening model had significantly lower costs (total cost savings of S$173 per person) while generating similar QALYs compared with the physician-based model (i.e., 13.1 QALYs). From the health system perspective that includes only direct medical costs, the cost savings are S$144 per person. By extrapolating these data to approximately 170 000 patients with diabetes currently being screened yearly for DR in Singapore's primary care polyclinics, the present value of future cost savings associated with the telemedicine-based model is estimated to be S$29.4 million over a lifetime horizon. While generating similar health outcomes, the telemedicine-based DR screening using technicians in the primary care setting saves costs for Singapore compared with the FP model. Our data provide a strong economic rationale to expand the telemedicine-based DR screening program in Singapore and elsewhere. Copyright © 2016 American Academy of Ophthalmology.

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 test the efficacy of a culturally targeted breast cancer screening educational program in increasing mammogram completion in Chinese-American immigrant women. Randomized controlled study. Chinese communities, Portland, Oregon. From April 2010 to September 2011, 300 women were randomized to receive a theory-based, culturally targeted breast cancer screening educational intervention (n = 147) or a mammography screening brochure published by the National Cancer Institute (n = 153). The two-part intervention consisted of group teaching with targeted, theory-based messages followed by individual counseling sessions. Mammography completion, perceived susceptibility, perceived benefits, perceived barriers, perceived cultural barriers, and demographic variables. A 2 × 3 mixed logistic model was applied to determine odds ratio of mammogram completion. Behavior changed in both groups, with a total of 170 participants (56.7%) reporting a mammogram at 12 months. The logistic model indicated increased odds of mammogram completion in the intervention compared to the control group at 3, 6, and 12 months. When controlling for marital status, age, and age moved to the United States, the intervention group was nine times more likely to complete mammograms than the control group. The culturally targeted educational program significantly increased mammogram use among Chinese immigrant women. Further testing of effectiveness in larger community settings is needed. The intervention may also serve as a foundation from which to develop education to increase cancer screening among other minority subgroups.

African American women are at high risk for morbidity and mortality from breast cancer. African American women ages 50 and older have been a difficult group to reach through conventional breast cancer intervention programs. Cultural and health beliefs that differ from mainstream society are reported to be factors contributing to the low rates of breast screening among this group. In addition to these attitudinal factors, older African American women are disproportionately represented among uninsured and under-insured Americans. As a result, cost becomes a barrier to mammography screening for many of these women. This project proposes to increase breast cancer screening awareness and provide a referral or free breast screening, or both, for African American women ages 50 and older. This information will be offered in the culturally familiar setting of local beauty salons. The culturally sensitive educational pamphlets developed by the National Cancer Institute (NCI) and video developed by the NCI-funded project, Cancer Prevention Research Unit, will be used to promote mammography, clinical breast examinations, and breast self-examination. Providers staffing a mobile mammography van provided by Dr. Anitha Mitchell of the Association of Black Women Physicians through a grant from the Breast and Cervical Cancer Control Program, funded by the Centers for Disease Control and Prevention, will perform mammograms for women on site during scheduled intervals. A followup telephone survey will be conducted. PMID:7630996

Analysis of digitized cervical images to detect cervical neoplasia

Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

China has a high prevalence of human papillomavirus (HPV) and a consequently high burden of disease with respect to cervical cancer. The HPV vaccine has proved to be effective in preventing cervical cancer and is now a part of routine immunization programs worldwide. It has also proved to be cost effective. This study aimed to assess the cost-effectiveness of 2-, 4-, and 9-valent HPV vaccines (hereafter, HPV2, 4 or 9) combined with current screening strategies in China. A Markov model was developed for a cohort of 100,000 HPV-free girls to simulate the natural history to HPV infection. Three recommended screening methods (1. liquid-based cytology test + HPV DNA test; 2. pap smear cytology test + HPV DNA test; 3. visual inspection with acetic acid) and three types of HPV vaccination program (HPV2/4/9) were incorporated into 15 intervention options, and the incremental cost-effectiveness ratio (ICER) was calculated to determine the dominant strategies. Costs, transition probabilities and utilities were obtained from a review of the literature and national databases. One-way sensitivity analyses and threshold analyses were performed for key variables in different vaccination scenarios. HPV9 combined with screening showed the highest health impact in terms of reducing HPV-related diseases and increasing the number of quality-adjusted life years (QALYs). Under the current thresholds of willingness to pay (WTP, 3 times the per capita GDP or USD$ 23,880), HPV4/9 proved highly cost effective, while HPV2 combined with screening cost more and was less cost effective. Only when screening coverage increased to 60% ~ 70% did the HPV2 and screening combination strategy become economically feasible. The combination of the HPV4/9 vaccine with current screening strategies for adolescent girls was highly cost-effective and had a significant impact on reducing the HPV infection-related disease burden in Mainland China.

The Taiwanese government has proposed a population-based colorectal tumor detection program for the average-risk population. This study's objectives were to understand the outcomes of these screening policies and to evaluate the effectiveness of the program. We compared two databases compiled in one medical center. The "policy-promoted cancer screening" (PPS) database was built on the basis of the policy of the Taiwan Bureau of National Health Insurance for cancer screening. The "health promotion service" (HPS) database was built to provide health check-ups for self-paid volunteers. Both the PPS and HPS databases employ the immunochemical fecal occult blood test (iFOBT) and colonoscopy for colorectal tumor screening using different strategies. A comparison of outcomes between the PPS and HPS included: (1) quality indicators-compliance rate, cecum reaching rate, and tumor detection rate; and (2) validity indicators-sensitivity, specificity, positive, and negative predictive values for detecting colorectal neoplasms. A total of 10,563 and 1481 individuals were enrolled in PPS and HPS, respectively. Among quality indicators, there was no statistically significant difference in the cecum reaching rate between PPS and HPS. The compliance rates were 56.1% for PPS and 91.8% for HPS (p < 0.001). The advanced adenoma detection rates of PPS and HPS were 1.0% and 3.6%, respectively (p < 0.01). The carcinoma detection rates were 0.3% and 0.4%, respectively (p = 0.59). For validity indicators, PPS provides only a positive predictive value for colorectal tumor detection. HPS provides additional validity indicators, including sensitivity, specificity, positive predictive value, and negative predictive value, for colorectal tumor screening. In comparison with the outcomes of the HPS database, the screening efficacy of the PPS database is even for detecting colorectal carcinoma but is limited in detecting advanced adenoma. HPS may provide comprehensive validity indicators and will be helpful in adjusting current policies for improving screening performance. Copyright © 2013. Published by Elsevier B.V.

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.

The importance of quality assurance in cancer screening has recently gained increasing attention in Japan. To evaluate and improve quality, checklists and process indicators have been developed. To explore effective methods of enhancing quality in cancer screening, we started a randomized control study of the methods of evaluation and feedback for cancer control from 2009 to 2014. We randomly assigned 1270 municipal governments, equivalent to 71% of all Japanese municipal governments that performed screening programs, into three groups. The high-intensity intervention groups (n = 425) were individually evaluated using both checklist performance and process indicator values, while the low-intensity intervention groups (n= 421) were individually evaluated on the basis of only checklist performance. The control group (n = 424) received only a basic report that included the national average of checklist performance scores. We repeated the survey for each municipality's quality assurance activity performance using checklists and process indicators. In this paper, we report our study design and the result of the baseline survey. The checklist adherence rates were especially low in the checklist elements related to invitation of individuals, detailed monitoring of process indicators such as cancer detection rates according to screening histories and appropriate selection of screening facilities. Screening rate and percentage of examinees who underwent detailed examination tended to be lower for large cities when compared with smaller cities for all cancer sites. The performance of the Japanese cancer screening program in 2009 was identified for the first time.

To evaluate, from a gynecology perspective, the transition from cytology-based HPV screening to primary HPV screening. Studies examining switching from cytology-based screening to primary HPV-DNA testing with triaging of patients with positive test results were retrieved and reviewed, with a particular focus on screening in an Italian setting. The increased complexity of patient-management decisions when implementing HPV-based screening was a critical issue discussed in the literature. The change in strategy represents a paradigm shift in moving from a medical perspective of identifying the disease in individual patients, to a public-healthcare perspective of excluding HPV from the healthy population and identifying a small sub-group of individuals at increased risk of HPV. With knowledge about HPV screening evolving rapidly, new programs and related algorithms need to be sufficiently flexible to be adjusted according to ongoing research and the validation of new assays. The establishment of a national working group (including epidemiologists, gynecologists, pathologists, and healthcare providers) will be necessary to properly implement and govern this important technical and cultural transition. © 2016 International Federation of Gynecology and Obstetrics.

The prevalence of cervical cancer is high among some groups of immigrants. Although there is evidence of low participation in cervical cancer screening programs among immigrants, studies have been subject to selection bias and accounted for few immigrant groups. The aim of this study was to compare the proportion of several groups of immigrants versus nonimmigrants attending the cervical cancer-screening program in Norway. In addition, we aimed to study predictors for attendance to the screening program. Register-based study using merged data from four national registries. All Norwegian-born women (1 168 832) and immigrant women (152 800) of screening age for cervical cancer (25-69 years) registered in Norway in 2008 were included. We grouped the immigrants by world's geographic region and carried out descriptive analyses and constructed several logistic regression models. The main outcome variable was whether the woman was registered with a Pap smear in 2008 or not. Immigrants had lower rates of participation compared with Norwegian-born women; Western Europe [adjusted odds ratio (OR), 95% confidence interval (CI): 0.84, 0.81-0.88], Eastern Europe (OR 0.64, 95% CI: 0.60-0.67), Asia (OR 0.74, 95% CI: 0.71-0.77), Africa (OR 0.61, 95% CI: 0.56-0.67) and South America (OR 0.87, 95% CI: 0.79-0.96). Younger age, higher income, residence in rural areas, and having a female general practitioner (GP) were associated with Pap smear. Longer residential time in Norway and having a nonimmigrant GP were associated with screening for some immigrant groups. Appropriate interventions targeting both immigrants and GPs need to be developed and evaluated.

Surgical management is a critical component of computed tomography (CT) screening for lung cancer. We report the results for US sites in a large ongoing screening program, the International Early Lung Cancer Action Program (I-ELCAP). We identified all patients who underwent surgical resection. We compared the results before (1993-2005) and after (2006-2011) termination of the National Lung Screening Trial to identify emerging trends. Among 31,646 baseline and 37,861 annual repeat CT screenings, 492 patients underwent surgical resection; 437 (89%) were diagnosed with lung cancer; 396 (91%) had clinical stage I disease. In the 54 (11%) patients with nonmalignant disease, resection was sublobar in 48 and lobectomy in 6. The estimated cure rate based on the 15-year Kaplan-Meier survival for all 428 patients (excluding 9 typical carcinoids) with lung cancer was 84% (95% confidence interval [CI], 80%-88%) and 88% (95% CI, 83%-92%) for clinical stage I disease resected within 1 month of diagnosis. Video-assisted thoracoscopic surgery and sublobar resection increased significantly, from 10% to 34% (P < .0001) and 22% to 34% (P = .01) respectively; there were no significant differences in the percentage of malignant diagnoses (90% vs 87%, P = .36), clinical stage I (92% vs 89%, P = .33), pathologic stage I (85% vs 82%, P = .44), tumor size (P = .61), or cell type (P = .81). The frequency and extent of surgery for nonmalignant disease can be minimized in a CT screening program and provide a high cure rate for those diagnosed with lung cancer and undergoing surgical resection.

Although there is evidence of low participation in cervical cancer screening programs among immigrants, studies have been subject to selection bias and accounted for few immigrant groups. The aim of this study was to compare the proportion of several groups of immigrants versus nonimmigrants attending the cervical cancer-screening program in Norway. In addition, we aimed to study predictors for attendance to the screening program. Register-based study using merged data from four national registries. All Norwegian-born women (1 168 832) and immigrant women (152 800) of screening age for cervical cancer (25–69 years) registered in Norway in 2008 were included. We grouped the immigrants by world’s geographic region and carried out descriptive analyses and constructed several logistic regression models. The main outcome variable was whether the woman was registered with a Pap smear in 2008 or not. Immigrants had lower rates of participation compared with Norwegian-born women; Western Europe [adjusted odds ratio (OR), 95% confidence interval (CI): 0.84, 0.81–0.88], Eastern Europe (OR 0.64, 95% CI: 0.60–0.67), Asia (OR 0.74, 95% CI: 0.71–0.77), Africa (OR 0.61, 95% CI: 0.56–0.67) and South America (OR 0.87, 95% CI: 0.79–0.96). Younger age, higher income, residence in rural areas, and having a female general practitioner (GP) were associated with Pap smear. Longer residential time in Norway and having a nonimmigrant GP were associated with screening for some immigrant groups. Appropriate interventions targeting both immigrants and GPs need to be developed and evaluated. PMID:27749381

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.

Background The assessment of neurodevelopmental effects in children associated with prenatal methylmercury exposure, from contaminated fish and seafood in the maternal diet, has recently been strengthened by adjustment for the negative confounding resulting from co-exposure to beneficial polyunsaturated fatty acids (PUFAs). Objectives We aimed to determine the cost-effectiveness of a periconceptional screening program of blood mercury concentration for women planning to become pregnant in Ontario, Canada. Fish intake recommendations would be provided for those found to have blood mercury levels above the intervention threshold. Methods Analysis was conducted using a combined decision tree/Markov model to compare the proposed screening intervention with standard care from a societal perspective over a lifetime horizon. We used the national blood mercury distributions of women 20–49 years of age reported in the Canadian Health Measures Survey from 2009 through 2011 to determine the cognitive deficits associated with prenatal methylmercury exposure for successful planned pregnancies. Outcomes modeled included the loss in quality of life and the remedial education costs. Value of information analysis was conducted to assess the underlying uncertainty around the model results and to identify which parameters contribute most to this uncertainty. Results The incremental cost per quality-adjusted life year (QALY) gained for the proposed screening intervention was estimated to be Can$18,051, and the expected value for a willingness to pay of Can$50,000/QALY to be Can$0.61. Conclusions Our findings suggest that the proposed periconceptional blood mercury screening program for women planning a pregnancy would be highly cost-effective from a societal perspective. The results of a value of information analysis confirm the robustness of the study’s conclusions. Citation Gaskin J, Rennie C, Coyle D. 2015.

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.

Background Untreated syphilis in pregnancy is associated with adverse clinical outcomes to the infant. In low- and middle-income countries in Asia and Latin America, 20%-30% of women are not tested for syphilis during pregnancy. We evaluated the cost-effectiveness of increasing the coverage for antenatal syphilis screening in 11 Asian and 20 Latin American countries, using a point-of-care immunochromatographic strip (ICS) test. Methods The decision analytical cost-effectiveness models reported incremental costs per disability-adjusted life years (DALYs) averted from the perspectives of the national health care payer. Clinical outcomes were stillbirths, neonatal deaths, and congenital syphilis. DALYs were computed using WHO disability weights. Costs included the ICS test, three injections of benzathine penicillin, and nurse wages. Country-specific inputs included the antenatal prevalence of syphilis and the proportion of women in the antenatal care setting that are screened for syphilis infection as reported in the 2014 WHO baseline report on global sexually transmitted infection surveillance. Country-specific data on the annual number of live births, proportion of women with at least one antenatal care visit, and per capita gross national income were also included in the model. Results The incremental cost/DALY averted of syphilis screening is US$53 (range: US$10-US$332; Prob<1*per capita GDP=99.71%) in Asia and US$60 (range: US$5-US$225; Prob<1*per capita GDP=99.77%) in Latin America. Universal screening may reduce the annual number of stillbirths by 20,344 and 4,270, neonatal deaths by 8,201 and 1,721, cases of congenital syphilis by 10,952 and 2,298, and avert 925,039 and 197,454 DALYs in the aggregate Asian and Latin American panel, respectively. Conclusion Antenatal syphilis screening is highly cost-effective in all the 11 Asian and 20 Latin American countries assessed. Our findings support the decision to expand syphilis screening in countries with currently low screening rates or continue national syphilis screening programs in countries with high rates.

Midlands Province started implementing the Isoniazid (INH) preventive therapy (IPT) program in January 2013. Shurugwi and Gokwe North were the piloting district hospitals. In May 2014, four more districts hospitals (Gokwe South, Gweru, Kwekwe and Zvishavane) started implementing IPT. Shurugwi District decentralized the program to its rural health facilities in January 2014. A review of the Shurugwi IPT program, 2013 data, indicated that the majority of eligible clients were not started on IPT. None out of the 400 eligible clients were started on IPT in November against the 100% target according to the World Health Organization and the National Tuberculosis (TB) Program. We conducted a study to evaluate the IPT program in Shurugwi District from January 2013 to August 2014. The logical framework approach was used to evaluate inputs, processes, outputs and outcomes of the IPT program. An interviewer administered questionnaire was used to collect data from key informants. Checklists were used to collect data from IPT program records. Sixteen health facilities were implementing IPT in Shurugwi District. All the facilities had TB screening tools and three did not have TB screening algorithms. The district experienced medicine stock outs in 2013. One formal training at district level and on job trainings in implementing health facilities were done. From January 2013 to August 2014, Shurugwi District screened 6794 antiretroviral (ART) clients for TB. Out of those screened, 5255 were eligible for IPT and 2831 (54%) were started on IPT. A total of 700 clients had completed the IPT 6 month's course by August 2014. The dropout rate due to INH toxicity and TB was 0.6% (n = 18) and 0.3% (n = 8) respectively. Fifty-three advocacy and community sensitization meetings were done. The program had no Information Education and Communication (IEC) materials. The IPT program in Shurugwi District achieved half its target. This could be due to inadequate formally trained staff, lack of IEC materials, inadequate advocacy and community sensitization, non-availability of the INH 300 mg single dose and inadequate INH 100 mg dose tablets in 2013. To improve the IPT program, there is need for routine advocacy, communication and social mobilization.

Biliary atresia is a major cause of extrahepatic obstructive jaundice in neonates. Early Kasai operation is the gold standard of treatment. In this study, we evaluated the effectiveness of stool color card screening by using claims data from the National Health Insurance Research Database. This was a retrospective cohort study. Data from medical charts of all inpatients who were diagnosed with biliary atresia from 1996 to 2008 were collected from Taiwan's National Health Insurance Research Database. Patients who received a Kasai operation or liver transplant were identified by the Operation code. The patients' gender, age at admission, and type of operation were collected and analyzed. From 1996 to 2008, the overall incidence of biliary atresia was 1.48 per 10,000 live births. The median age at first admission for patients with suspected biliary atresia decreased after the implementation of stool color card screening (47 vs 43 days). The proportion of very late referral decreased from 9.5% to 4.9%. The median age of Kasai operation advanced from 51 to 48 days. The proportions of Kasai operation within 60 days of age were 68.9% before and 73.6% after screening program. Stool color card screening seemed to increase parents' and physicians' awareness of biliary atresia. It also was associated with a decline in the proportion of late referral. Thus, screening might be especially effective in areas with high a proportion of late referral. Improvements in the speed of workup and the operation room should be the focus of education and training in the future.

To survey person centered survival rate in population based screening program by an intelligent clinical decision support system. Colorectal cancer is the most common malignancy and major cause of morbidity and mortality throughout the world. Colorectal cancer is the sixth leading cause of cancer death in Iran. In this survey, we used cosine similarity as data mining technique and intelligent system for estimating survival of at risk groups in the screening plan. In the first step, we determined minimum data set (MDS). MDS was approved by experts and reviewing literatures. In the second step, MDS were coded by python language and matched with cosine similarity formula. Finally, survival rate by percent was illustrated in the user interface of national intelligent system. The national intelligent system was designed in PyCharm environment. Main data elements of intelligent system consist demographic information, age, referral type, risk group, recommendation and survival rate. Minimum data set related to survival comprise of clinical status, past medical history and socio-demographic information. Information of the covered population as a comprehensive database was connected to intelligent system and survival rate estimated for each patient. Mean range of survival of HNPCC patients and FAP patients were respectively 77.7% and 75.1%. Also, the mean range of the survival rate and other calculations have changed with the entry of new patients in the CRC registry by real-time. National intelligent system monitors the entire of risk group and reports survival rates by electronic guidelines and data mining technique and also operates according to the clinical process. This web base software has a critical role in the estimation survival rate in order to health care planning.

Burden of colorectal cancer in Central and South America.

The colorectal cancer (CRC) burden is increasing in Central and South American due to an ongoing transition towards higher levels of human development. We describe the burden of CRC in the region and review the current status of disease control. We obtained regional- and national-level incidence data from 48 population-based cancer registries in 13 countries, as well as cancer deaths from the WHO mortality database for 18 countries. We estimated world population age-standardized incidence (ASR) and mortality (ASMR) rates per 100,000 person-years for 2003-2007 and the estimated annual percentage change for 1997-2008. The CRC rate in males was 1-2 times higher than that in females. In 2003-2007, the highest ASRs were seen in Uruguayan, Brazilian and Argentinean males (25.2-34.2) and Uruguayan and Brazilian females (21.5-24.7), while El Salvador had the lowest ASR in both sexes (males: 1.5, females: 1.3). ASMRs were<10 for both sexes, except in Uruguay, Cuba and Argentina (10.0-17.7 and 11.3-12.0). CRC incidence is increasing in Chilean males. Most countries have national screening guidelines. Uruguay and Argentina have implemented national screening programs. Geographic variation in CRC and sex gaps may be explained by differences in the prevalence of obesity, physical inactivity, diet, smoking and alcohol consumption, early detection, and cancer registration practices. Establishing optimal CRC screening programs is challenging due to lack of healthcare access and coverage, funding, regional differences and inadequate infrastructure, and may not be feasible. Given the current status of CRC in the region, data generated by population-based cancer registries is crucial for cancer control planning.

1987-01-01

Serious questions have been raised by Congress about the usefulness of water-quality data for addressing issues of regional and national scope and, especially, for characterizing the current quality of the Nation's streams and ground water. In response, the U.S. Geological Survey has undertaken a pilot study in Colorado and Ohio to (1) determine the characteristics of current (1984) water-quality data-collection activities of Federal, regional, State, and local agencies, and academic institutions; and (2) determine how well the data from these activities, collected for various purposes and using different procedures, can be used to improve our ability to answer major broad-scope questions, such as:A. What are (or were) natural or near-natural water-quality conditions?B. What are existing water-quality conditions?C. How has water quality changed, and how do the changes relate to human activities?Colorado and Ohio were chosen for the pilot study largely because they represent regions with different types of waterquality concerns and programs. The study has been divided into three phases, the objectives of which are: Phase I--Inventory water-quality data-collection programs, including costs, and identify those programs that met a set of broad criteria for producing data that are potentially appropriate for water-quality assessments of regional and national scope. Phase II--Evaluate the quality assurance of field and laboratory procedures used in producing the data from programs that met the broad criteria of Phase I. Phase III--Compile the qualifying data and evaluate the adequacy of this data base for addressing selected water-quality questions of regional and national scope.Water-quality data are collected by a large number of organizations for diverse purposes ranging from meeting statutory requirements to research on water chemistry. Combining these individual data bases is an appealing and potentially cost-effective way to attempt to develop a data base adequate for regional or national water-quality assessments. However, to combine data from diverse sources, field and laboratory procedures used to produce the data need to be equivalent and need to meet specific qualityassurance standards. It is these factors that are the focus of Phase II, which is described in this report. In the first phase of this study, an inventory was made of all public organizations and academic institutions that undertook water-quality data-collection activities in Colorado and Ohio in 1984. Water-quality programs identified in Phase I were tested against a set of broad screening criteria. A total of 44 waterquality programs in Colorado and 29 programs in Ohio passed the Phase-I screen and were examined in Phase II. These programs accounted for an estimated 165,000 analyses in Colorado and 76,300 analyses in Ohio for 20 selected constituents and properties. Although qualifying programs included both surface- and ground-water sampling, they emphasized surface waters and produced few groundwater analyses (3,660 for Colorado and 470 for Ohio). For Phase II, information about field and laboratory qualityassurance practices was provided by each organization and its supporting laboratories through questionnaires. This information was evaluated against a set of specific criteria for field and laboratory practices. The criteria were developed from guidelines published by public agencies and professional organizations such as the American Public Health Association, the U.Sc, Environmental Protection Agency, and the U.S. Geological Survey. Each of the eight criteria that comprise the Phase-II screen fall into one of two major categories--field practices or laboratory practices.

Projected national impact of colorectal cancer screening on clinical and economic outcomes and health services demand.

PubMed

Ladabaum, Uri; Song, Kenneth

2005-10-01

Colorectal cancer (CRC) screening is effective and cost-effective, but the potential national impact of widespread screening is uncertain. It is controversial whether screening colonoscopy can be offered widely and how emerging tests may impact health services demand. Our aim was to produce integrated, comprehensive estimates of the impact of widespread screening on national clinical and economic outcomes and health services demand. We used a Markov model and census data to estimate the national consequences of screening 75% of the US population with conventional and emerging strategies. Screening decreased CRC incidence by 17%-54% to as few as 66,000 cases per year and CRC mortality by 28%-60% to as few as 23,000 deaths per year. With no screening, total annual national CRC-related expenditures were 8.4 US billion dollars. With screening, expenditures for CRC care decreased by 1.5-4.4 US billion dollars but total expenditures increased to 9.2-15.4 US billion dollars. Screening colonoscopy every 10 years required 8.1 million colonoscopies per year including surveillance, with other strategies requiring 17%-58% as many colonoscopies. With improved screening uptake, total colonoscopy demand increased in general, even assuming substantial use of virtual colonoscopy. Despite savings in CRC care, widespread screening is unlikely to be cost saving and may increase national expenditures by 0.8-2.8 US billion dollars per year with conventional tests. The current national endoscopic capacity, as recently estimated, may be adequate to support widespread use of screening colonoscopy in the steady state. The impact of emerging tests on colonoscopy demand will depend on the extent to which they replace screening colonoscopy or increase screening uptake in the population.

By comparing the Universal Neonatal Hearing Screening (UNHS) program as implemented in Shanghai and other regions in China and countries around the world, this study makes an assessment of the Shanghai model and summarizes the experiences implementing the UNHS program, so as to provide a valuable reference for other countries or regions to carry out UNHS more effectively. Since Shanghai is one of the most developed regions in China, we also examined the relationship between economic development and the UNHS starting year and coverage rate. The study conducted a systematic review of published studies in Chinese and English on the program status of neonatal hearing screening to compare and analyze the implementation of the UNHS program in 20 cities or provinces in China and 24 regions or countries around the world. The literature search in Chinese was conducted in the three most authoritative publication databases, CNKI (China National Knowledge Infrastructure), WANFANGDATA, and CQVIP (http://www.cqvip.com/). We searched all publications in those databases with the keywords "neonatal hearing screening" (in Chinese) between 2005 and 2014. English literature was searched using the same keywords (in English). The publication database included Medline and Web of Science, and the search time period was 2000-2014. Shanghai was one of the first regions in China to implement UNHS, and its coverage rate was among the top regions by international comparison. The starting time of the UNHS program had no relationship with the Gross Domestic Product (GDP) per capita in the same year. Economic level serves as a threshold for carrying out UNHS but is not a linear contributor to the exact starting time of such a program. The screening coverage rate generally showed a rising trend with the increasing GDP per capita in China, but it had no relationship with the area's GDP per capita in selected regions and countries around the world. The system design of UNHS is the key factor influencing screening coverage. Policy makers, program administrators, and cost-sharing structures are important factors that influence the coverage rates of UNHS. When to carry out a UNHS program is determined by the willingness and preference of the local government, which is influenced by the area's social, political and cultural conditions. Mandatory hearing screening and minimal-cost to no-cost intervention are two pillars for a good coverage rate of UNHS. In terms of system design, decision-making, implementation, funding and the concrete implementation plan are all important factors affecting the implementation of the UNHS.

A cohort of women enrolled in the Mama breast self-examination-(BSE) containing breast screening program in Finland from 1973 through 1975 (with BSE used for screening and mammography for diagnosis) was studied. Twenty-eight thousand seven hundred eighty-five women who returned calendars recording their practice of BSE over a 2-year period have been followed by linkage with the records of the Finnish Cancer Registry through 1986. The incidence of and mortality from breast cancer was compared with that expected in the Finnish population based on a model incorporating Finnish national data for breast cancer incidence and case fatality. Breast cancer incidence was higher than expected (a rate ratio of 1.19 over all ages). The stage distribution of cases was not different from that expected from Finnish cancer registry data for 1980, but the breast cancer mortality was lower than expected (a rate ratio of 0.75). The latter difference occurred mainly in Years 3-6 of the follow-up period. The effect seemed similar in women under and over the age of 50 years. The cohort was of higher educational status than the Finnish population, and the mortality from all causes was lower than the general Finnish population, an effect seen in previous studies of compliers with breast screening. The reduction in mortality from breast cancer in the study cohort is consistent with an effect of the BSE-containing Mama program, though selection bias, inherent in any observational study of screening, provided an alternative explanation for the findings.

Type 2 diabetes (T2D) and its precursor, impaired glucose tolerance (IGT), are now reaching epidemic proportions among Aboriginal Canadians. Of particular concern is the appearance and increasing prevalence of T2D and IGT among Aboriginal youth. At the request of three communities in the Tsimshian nation on the northern coast of British Columbia (with which the Department of Pediatrics, University of British Columbia, had a pre-existing partnership) a screening program was undertaken to determine the prevalence of T2D and IGT among the children. The long-term goal was the collaborative development of intervention programs for each community. The challenges of meeting this request included the sociological and ethical issues associated with research in First Nations communities, as well as the pragmatic issues of conducting complex research in remote communities. Three separate visits were undertaken to respect the cultural dynamics and capacity of the community to accommodate a project of this magnitude. The process began with dialogue, listening and presentations to the community. Only then began the planning of logistics and application for funding. Next, the team visited the communities to ensure understanding of exactly what was involved for the community, each child and family, and to be certain that consent was fully informed. For the diabetes screening visit, special arrangements including chartering a Beaver float plane were needed for the transport of the five-member team with all the necessary equipment, including a -20(o)C freezer to safeguard the integrity of blood samples. The 100% consent rate, successful conduct of study, and retention of community support achieved by the process, indicate that population-based clinical research is possible in remote First Nations communities. This is best achieved with appropriate dialogue, care, respect and planning to overcome the sociological, ethical and practical challenges.

Computerized reminders for five preventive screening tests: generation of patient-specific letters incorporating physician preferences.

2000-01-01

Compliance with preventive screening tests is inadequate in the United States. We describe a computer based system for generating reminder letters to patients who may have missed their indicated screening tests because they do not visit a provider regularly or missed their tests despite the fact that they do visit a provider. We started with national recommendations and generated a local consensus for test indications. We then used this set of indications and our electronic record to determine test deficiencies in our pilot pool of 3073 patients. The computer generated customized reminder letters targeting several tests. Physicians chose any patients who should not receive letters. The response rate for fecal occult blood (FOB) testing was 33% compared with an 18% historical compliance rate within the same community. FOB reminders generated improved test compliance. Test execution must be considered when commencing a program of screening test reminders. PMID:11079954

2009-01-01

The purpose of this study was to explore the rationale provided by program directors and general managers of health/fitness facilities for low adherence to nationally accepted standards related to pre-activity cardiovascular screening procedures (PACSPs) for members and clients of personal trainers. Qualitative interviews were conducted with the directors/managers in a Midwest region representing 76 facilities who indicated they did not conduct PACSPs for members and clients of personal trainers. Analysis of the rationale provided revealed 6 major clusters: (1) Purpose or need for screening; (2) time and staffing; (3) barrier to participation; (4) personal responsibility for health and actions; (5) legal issues; and (6) company or franchise policy that categorized the reasons for low adherence to PACSPs. These findings highlight the need to increase awareness of the relevance of PACSPs among health/fitness managers, staff members, and current exercise science students as well as engage those in risk management for informed dialogue for consistent application of the standard of care.

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.

Few studies have evaluated the epidemiology of cervical cancer in low risk Muslim countries, where the prognosis of cervical cancer is poor and which lack an organized cervical screening program. We studied incidence and mortality rates of cervical cancer and the prevalence of high risk human papilloma virus (HPV) infection in the Islamic Republic (I.R.) of Iran. We analyzed national cancer and mortality registration data and estimated age-standardized incidence (ASR) and mortality (ASMR) rates and age-specific patterns of cervical cancer. Furthermore, based on a systematic review we estimated prevalence of HPV infection in Iran. The mean cervical cancer ASR was 2.5 per 100,000 in pathology-based cancer registries. However, ASRs were almost double in the population-based cancer registry and reached 6 per 100,000. The mean cervical cancer ASMR for Iran was 1.04 per 100,000. The mortality to incidence ratio was 42%. The cervical cancer incidence rate increased after age 30 and peaked between ages 55 and 65. The prevalence of HPV infection was 76% in cervical cancer patients and 7% among healthy Iranian women. Of the HPV types isolated, HPV 16 (54%), 18 (14%), and 31 (6%) were the most commonly detected in Iranian cervical cancer patients. An organized prevention program is needed to fight against cervical cancer in Iran and other low incidence countries. We suggest a screening program starting after age 30 and with at least three screenings tests over each woman's lifetime. With a reservation on cost-effectiveness issue, available HPV vaccine will prevent HPV infection and cervical cancer in Iran. Copyright © 2012 Elsevier Inc. All rights reserved.

Equity in human papilloma virus vaccination uptake?: sexual behaviour, knowledge and demographics in a cross-sectional study in (un)vaccinated girls in the Netherlands

PubMed Central

2014-01-01

Background In the Netherlands, human papillomavirus (HPV) vaccination is part of a national program equally accessible for all girls invited for vaccination. To assess possible inequalities in vaccine uptake, we investigated differences between vaccinated and unvaccinated girls with regard to various characteristics, including education and ethnicity, (both associated with non-attendance to the national cervical screening program), sexual behaviour and knowledge of HPV. Methods In 2010, 19,939 nationwide randomly-selected 16–17 year-old girls (2009 vaccination campaign) were invited to fill out an online questionnaire. A knowledge scale score and multivariable analyses identified variables associated with vaccination status. Results 2989 (15%) of the selected girls participated (65% vaccinated, 35% unvaccinated). The participants were comparable with regard to education, ethnicity, most sexual risk behaviour and had similar knowledge scores on HPV transmission and vaccination. However, unvaccinated girls lived in more urbanised areas and were more likely to have a religious background. Irrespective of vaccination status, 81% of the girls were aware of the causal relationship between HPV and cervical cancer, but the awareness of the necessity of cervical screening despite being vaccinated was limited. Conclusions HPV vaccine uptake was not associated with knowledge of HPV and with factors that are known to be associated with non-attendance to the cervical cancer screening program in the Netherlands. Furthermore, most sexual behaviour was not related to vaccination status meaning that teenage unvaccinated girls were not at a disproportionally higher risk of being exposed to HPV. Routine HPV vaccination may reduce the social inequity of prevention of cervical cancer. PMID:24679163

Screening for Wilms tumor and hepatoblastoma in children with Beckwith-Wiedemann syndromes: a cost-effective model.

We undertook a cost-benefit analysis of screening for Wilms tumor and hepatoblastoma in children with Beckwith-Wiedemann syndrome (BWS), a known cancer predisposition syndrome. The purpose of this analysis was twofold: first, to assess whether screening in children with BWS has the potential to be cost-effective; second, if screening appears to be cost-effective, to determine which parameters would be most important to assess if a screening trial were initiated. We used data from the BWS registry at the National Cancer Institute, the National Wilms Tumor Study (NWTS), and large published series to model events for two hypothetical cohorts of 1,000 infants born with BWS. One hypothetical cohort was screened for cancer until a predetermined age, representing the base case. The other cohort was unscreened. For our base case, we assumed: (a) sonography examinations three times yearly (triannually) from birth until 7 years of age; (b) screening would result in one stage shift downward at diagnosis for Wilms tumor and hepatoblastoma; (c) 100% sensitivity and 95% specificity for detecting clinical stage I Wilms tumor and hepatoblastoma; (d) a 3% discount rate; (e) a false positive result cost of $402. We estimated mortality rates based on published Wilms tumor and hepatoblastoma stage specific survival. Using the base case, screening a child with BWS from birth until 4 years of age results in a cost per life year saved of $9,642 while continuing until 7 years of age results in a cost per life-year saved of $14,740. When variables such as cost of screening examination, discount rate, and effectiveness of screening were varied based on high and low estimates, the incremental cost per life-year saved for screening up until age four remained comparable to acceptable population based cancer screening ranges (< $50,000 per life year saved). Under our model's assumptions, abdominal sonography examinations in children with BWS represent a reasonable strategy for a cancer screening program. A cancer screening trial is warranted to determine if, when, and how often children with BWS should be screened and to determine cost-effectiveness in clinical practice.

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.

Estimation of the tumor size at cure threshold among aggressive non-small cell lung cancers (NSCLCs): evidence from the surveillance, epidemiology, and end results (SEER) program and the national lung screening trial (NLST).

The National Lung Screening Trial (NLST) demonstrated that non-small cell lung cancer (NSCLC) mortality can be reduced by a program of annual CT screening in high-risk individuals. However, CT screening regimens and adherence vary, potentially impacting the lung cancer mortality benefit. We defined the NSCLC cure threshold as the maximum tumor size at which a given NSCLC would be curable due to early detection. We obtained data from 518,234 NSCLCs documented in the U.S. SEER cancer registry between 1988 and 2012 and 1769 NSCLCs detected in the NLST. We demonstrated mathematically that the distribution function governing the cure threshold for the most aggressive NSCLCs, G(x|Φ = 1), was embedded in the probability function governing detection of SEER-documented NSCLCs. We determined the resulting probability functions governing detection over a range of G(x|Φ = 1) scenarios and compared them with their expected functional forms. We constructed a simulation framework to determine the cure threshold models most consistent with tumor sizes and outcomes documented in SEER and the NLST. Whereas the median tumor size for lethal NSCLCs documented in SEER is 43 mm (males) and 40 mm (females), a simulation model in which the median cure threshold for the most aggressive NSCLCs is 10 mm (males) and 15 mm (females) best fit the SEER and NLST data. The majority of NSCLCs in the NLST were treated at sizes greater than our median cure threshold estimates. New technology is needed to better distinguish and treat the most aggressive NSCLCs when they are small (i.e., 5-15 mm). © 2016 UICC.

Patient navigation is emerging as a standard in breast cancer care delivery, yet multi-site data on the impact of navigation at reducing delays along the continuum of care are lacking. The purpose of this study was to determine the effect of navigation on reaching diagnostic resolution at specific time points after an abnormal breast cancer screening test among a national sample. A prospective meta-analysis estimated the adjusted odds of achieving timely diagnostic resolution at 60, 180, and 365 days. Exploratory analyses were conducted on the pooled sample to identify which groups had the most benefit from navigation. Clinics from six medical centers serving vulnerable populations participated in the Patient Navigation Research Program. Women with an abnormal breast cancer screening test between 2007 and 2009 were included and received the patient navigation intervention or usual care. Patient navigators worked with patients and their care providers to address patient-specific barriers to care to prevent delays in diagnosis. A total of 4675 participants included predominantly racial/ethnic minorities (74 %) with public insurance (40 %) or no insurance (31 %). At 60 days and 180 days, there was no statistically significant effect of navigation on achieving timely diagnostic care, but a benefit of navigation was seen at 365 days (aOR 2.12, CI 1.36–3.29). We found an equal benefit of navigation across all groups, regardless of race/ethnicity, language, insurance status, and type of screening abnormality. Patient navigation resulted in more timely diagnostic resolution at 365 days among a diverse group of minority, low-income women with breast cancer screening abnormalities. PMID:27432417

A mandatory National Premarital Thalassemia Screening Program was implemented in Jordan in 2004. This cross-sectional study aimed to assess the knowledge and attitudes of university students in North Jordan toward this program. Data was collected from 542 students from four universities (two public and two private universities) located in North Jordan, using a structured questionnaire. Results of t-test and analysis of variance (ANOVA) showed that while respondents had adequate knowledge of and positive attitudes toward the premarital screening program, there was still a lack of knowledge about the disease itself. Nearly half the respondents were under the impression that β-thalassemia (β-thal) is a disease that can be treated simply. One-third of the respondents believed that if both partners were carriers of β-thal they should proceed with marriage. Negative attitude was revealed when many respondents believed that diagnosing a family member as a carrier affects other family members' future marriage opportunities. Significant associations were detected between the knowledge scores and gender, urban/rural residence, and the university where the students were enrolled. Students in private universities showed significantly lower attitude scores. Consideration of prenatal diagnostic services as part of a β-thal prevention program is necessary. It would also be helpful to include information about β-thal as a preventable inherited illness with a severe debilitating impact on the family in the high school curriculum. There is also a need for social marketing of the program.

In Mexico, more of 36% of malignant tumors in the women are cervical cancer, representing an important public health problem. Although cytologic screening for cervical cancer was introduced in 1974, the mortality rate for this disease has been increasing. The state of Durango represents the second national place in mortality by CaCu (3.4/100,000). Since there are few the studies of DOC program evaluation in Mexico were considered important to evaluated the cervical screening program (coverage, assiduity, diagnoses and pursuit) in the state of Durango. Of 40,000 active sexually women attended in the IMSS; we received 11,185 slides during May of 1999 to April of 2000 for cytologic screening. The coverage in this population was 27.96% (11,185/40,000), 8,187 women (73.2%) had cytologic control at least previous two years, 652 (5.83%) had more of four years without control and 2,346 (21%) assisted for first time. The cytological diagnostic showed 189 abnormal Pap (1.68%), and only 40 of them (21.16%) had cytohistopatholgic pursuit and clinic treatment. According to these results we concluded that DOC program in Gomez Palacio, Durango has a deficiency of coverage (72.04%) and pursuit (78.84%). These results indicated the need for development institutional activities of prevention for increase efficiency of preventive services.

This study, funded by the National Cancer Institute, assessed cancer awareness and service needs in the Republic of the Marshall Islands (RMI). Findings suggest that cancer is the second-leading cause of death in the RMI and is, in part, a consequence of 12 years of nuclear testing in this region of the Pacific. However, cancer-related services are lacking. Assistance is needed to establish a national cancer registry, to increase public awareness about cancer and related risk factors, and to develop and implement a cancer prevention and screening program.

Background: Recently, a national breast cancer screening program has been introduced in Iran.The aim of this study was to examine the determinants of breast cancer screening uptake among Kurdish women, in order to identify those characteristics that may be potentially associated with the screening uptake. Methods: Through a cross sectional study, in 2014, a random sample of 561 women aged 40 years and older without the history of breast cancer and identified with Kurdish background in Baneh county, Iran, were recruited and interviewed by two trained interviewers. Data were collected using a valid and reliable researcher made questionnaire. Univariate and multivariate logistic regression models with self-reported screening history as the dependent variable were used to estimate the odds ratios (ORs) with 95% of CI. Results: The mean age of women was 43.64 (SD = 5.17). The participation rate in the mammography program was 16.8% (95% CI: 13.7-19.8%). The lowest level of participation was found among women aged 60 and older (OR = 0.30, 95% CI: 0.14-0.69), illiterate (OR = 0.63,95% CI: 0.40-0.99) and post-menopausal (OR = 0.56, 95% CI: 0.35-0.91) women. Conclusion: It was found that the level of breast screening uptake was low among Kurdish women compared to those reported in the previous studies. Designing participation enhancing interventions with a specific focus on older, illiterate and post-menopausal women are recommended. PMID:27123436

To investigate the effectiveness of a screening tool to enhance clinical trial participation at a community radiation oncology center involved in a National Cancer Institute-funded disparities program but lacking on-site clinical trials personnel. The screening form was pasted to the front of the charts and filled out for all new patients over the 9-month period of the study, during which time five external beam radiation therapy (EBRT) trials and a patient perception study were open for accrual. Patient consent was obtained by assorted personnel at several different sites. Patients potentially eligible for a trial were identified and approached by one of the clinic staff. Patients who were under- or uninsured, age > 80 years, members of an racial/ethnic minority, or recipients of medical assistance were identified as at risk for health care disparities and were offered patient navigator services. Of 196 patients consulted during the study, 144 were treated with EBRT. Of the 24 patients eligible for EBRT trials, 23 were approached (one had an incomplete screening form), and 15 accepted. Of 77 patients eligible for a patient perception trial, 72 were approached (five had incomplete forms), and 45 accepted. The eligibility and acceptance rates for EBRT trials were similar for disparities and nondisparities patients. Screening was completed for 96 patients (67%). When completed, the screening tool ensured clinical trial accrual. The major factor limiting overall accrual was a shortage of available trials.

2016-01-01

Background Diabetic Retinopathy (DR) is a leading cause of blindness worldwide even though successful treatments exist. Improving screening and treatment could avoid many cases of vision loss. However, due to an increasing prevalence of diabetes, traditional in-person screening for DR for every diabetic patient is not feasible. Telemedicine is one viable solution to provide high-quality and efficient screening to large number of diabetic patients. Purpose To provide a narrative review of large DR telemedicine screening programs. Methods Articles were identified through a comprehensive search of the English-language literature published between 2000 and 2014. Telemedicine screening programs were included for review if they had published data on at least 150 patients and had available validation studies supporting their model. Screening programs were then categorized according to their American Telemedicine Association Validation Level. Results Seven programs from the US and abroad were identified and included in the review. Three programs were Category 1 programs (Ophdiat, EyePacs, and Digiscope), two were Category 2 programs (Eye Check, NHS Diabetic Eye Screening Program), and two were Category 3 programs (Joslin Vision Network, Alberta Screening Program). No program was identified that claimed category 4 status. Programs ranged from community or city level programs to large nationwide programs including millions of individuals. The programs demonstrated a high level of clinical accuracy in screening for DR. There was no consensus amongst the programs regarding the need for dilation, need for stereoscopic images, or the level of training for approved image graders. Conclusion Telemedicine programs have been clinically validated and successfully implemented across the globe. They can provide a high-level of clinical accuracy for screening for DR while improving patient access in a cost-effective and scalable manner. PMID:27430019

Should low-income countries invest in breast cancer screening?

2016-11-01

With the increase in incidence and mortality of breast cancer in low-income countries (LICs), the question of whether LICs should promote breast cancer screening for early detection has gained tremendous importance. Because LICs have limited financial resources, the value of screening must be carefully considered before integrating screening programs into national healthcare system. Mammography-the most commonly used screening tool in developed countries-reduces breast cancer-specific mortality among women of age group 50-69, but the evidence is not so clear for younger women. Further, it does not reduce the overall mortality. Because the women in LICs tend to get breast cancer at younger age and are faced with various competing causes of mortality, LICs need to seriously evaluate whether mammographic screening presents a good value for the investment. Instead, we suggest a special module of clinical breast examination that could provide similar benefits at a very low cost. Nevertheless, we believe that LICs would obtain a much greater value for their investment if they promote primary prevention by tobacco cessation, healthier food and healthier lifestyle campaigns instead.

By December 1968, the Anaheim Family Life and Sex Education (FLSE) program, celebrated since its formal introduction in 1965 as one of the most progressive in the nation, was being smeared as communistic and perverse. Local activists in this Orange County city had been congregating in hotel rooms and homes, screening cautionary films for the…

Introduction The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides access to breast and cervical cancer screening for low-income, uninsured, and underinsured women in all states and US territories. In Idaho, a rural state with very low breast and cervical cancer screening rates, this program is called Women’s Health Check (WHC). The program has been operating continuously since 1997 and served 4,719 enrollees in 2013. The objective of this study was to assess whether disparities existed in cause-specific survival (a net survival measure representing survival of a specified cause of death in the absence of other causes of death) between women screened by WHC and outside WHC and to determine how type of surgery or survival varies with stage at diagnosis. Methods WHC data were linked to Idaho’s central cancer registry to compare stage distribution, type of surgery, and cause-specific survival between women with WHC-linked breast cancer and a comparison group of women whose records did not link to the WHC database (nonlinked breast cancer). Results WHC-linked breast cancer was significantly more likely to be diagnosed at a later stage of disease than nonlinked breast cancer. Because of differences in stage distribution between WHC-linked and nonlinked breast cancers, overall age-standardized, cause-specific breast cancer survival proportions diverged over time, with a 5.1 percentage-point deficit in survival among WHC-linked cases at 5 years of follow-up (83.9% vs 89.0%). Differences in type of surgery and cause-specific survival were attenuated when controlling for stage. Conclusion This study suggests that disparities may exist for Idaho WHC enrollees in the timely diagnosis of breast cancer. To our knowledge, this is the first study to publish comparisons of cause-specific breast cancer survival between NBCCEDP-linked and nonlinked cases. PMID:25789497

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.

The inclusion of severe combined immunodeficiency (SCID) in a Europe-wide screening program is currently debated. In making a case for inclusion in the French newborn screening program, we explored the costs incurred and potentially saved by early management of SCID. For test costs, a microcosting study documented the resources used in a laboratory piloting a newborn screening test on Guthrie cards using the T-cell receptor excision circle quantification method. For treatment costs, patients with SCID admitted to the national reference center for primary immunodeficiency in France between 2006 and 2010 were included. Costs of admission were estimated from actual national production costs. We estimated the costs for patients who underwent early versus delayed hematopoietic stem cell transplantation (HSCT; age, ≤3 vs. >3 months, respectively). The unit cost of the test varied between €4.69 and €6.79 for 33,800 samples per year, depending on equipment use and saturation. Of the 30 patients included, 27 underwent HSCT after age 3 months. At 1 year after HSCT, 10 of these had died, and all 3 patients undergoing early transplantation survived. The medical costs for HSCT after 3 months were €195,776 (interquartile range, €165,884-€257,160) versus €86,179 (range, €59,014-€272,577) when performed before 3 months of age. In patients undergoing late transplantation, active infection contributed to high cost and poor outcome. Early detection of SCID could reduce the cost of treatment by €50,000-100,000 per case. Assuming a €5 unit cost per test, the incidence required to break even is 1:20,000; however, if the survival advantage of HSCT before 3 months is confirmed, universal screening is likely to be cost-effective.

New High Throughput Methods to Estimate Chemical ...

EPA Pesticide Factsheets

EPA has made many recent advances in high throughput bioactivity testing. However, concurrent advances in rapid, quantitative prediction of human and ecological exposures have been lacking, despite the clear importance of both measures for a risk-based approach to prioritizing and screening chemicals. A recent report by the National Research Council of the National Academies, Exposure Science in the 21st Century: A Vision and a Strategy (NRC 2012) laid out a number of applications in chemical evaluation of both toxicity and risk in critical need of quantitative exposure predictions, including screening and prioritization of chemicals for targeted toxicity testing, focused exposure assessments or monitoring studies, and quantification of population vulnerability. Despite these significant needs, for the majority of chemicals (e.g. non-pesticide environmental compounds) there are no or limited estimates of exposure. For example, exposure estimates exist for only 7% of the ToxCast Phase II chemical list. In addition, the data required for generating exposure estimates for large numbers of chemicals is severely lacking (Egeghy et al. 2012). This SAP reviewed the use of EPA's ExpoCast model to rapidly estimate potential chemical exposures for prioritization and screening purposes. The focus was on bounded chemical exposure values for people and the environment for the Endocrine Disruptor Screening Program (EDSP) Universe of Chemicals. In addition to exposure, the SAP

The aim of the study was to test whether a screening navigation program leads to more favorable health beliefs and decreases social inequalities in them. The selected 261 noncompliant participants in a screening navigation versus a usual screening program arm had to respond to health belief measures inspired by the Protection Motivation Theory. Regression analyses showed that social inequalities in perceived efficacy of screening, favorable attitude, and perceived facility were reduced in the screening navigation compared to the usual screening program. These results highlight the importance of health beliefs to understand the mechanism of screening navigation programs in reducing social inequalities. © The Author(s) 2014.

Hybrid organic-inorganic halide perovskites with the prototype material of CH3NH3PbI3 have recently attracted much interest as low-cost and high-performance photovoltaic absorbers but one would like to improve their stability and get rid of toxic Pb. We used photovoltaic-functionality-directed materials screening approach to rationally design via first-principles DFT calculations Pb-free halide perovskites. Screening criteria involve thermodynamic and crystallographic stability, as well as solar band gaps, light carrier effective masses, exciton binding, etc. We considered both single atomic substitutions in AMX3 normal perovskites (altering chemical constituents of A, M and X individually) as well as double substitution of 2M into B+C in A2BCX6 double-perovskites. Chemical trends in phase stabilities and optoelectronic properties are discussed with some promising cases exhibiting solar cell efficiencies comparable to that of CH3NH3PbI3.

Both human papillomavirus (HPV) vaccination and screening/treatment are relatively simple and inexpensive to implement at all resource levels, and cervical cancer screening has been acknowledged as a "best buy" by the WHO. However, coverage with these interventions is low where they are needed most. Failure to launch or expand cervical cancer prevention programs is by and large due to the absence of dedicated funding, along with a lack of recognition of the urgent need to update policies that can hinder access to services. Clear and sustained communication, robust advocacy, and strategic partnerships are needed to inspire national governments and international bodies to action, including identifying and allocating sustainable program resources. There is significant momentum for expanding coverage of HPV vaccination and screening/preventive treatment in low-resource settings as evidenced by new global partnerships espousing this goal, and the participation of groups that previously had not focused on this critical health issue. © 2017 The Authors.

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

Making rational decisions about screening requires information about its harms, but high-quality evidence is often either not available or not used. One reason may be that we lack a coherent framework, a taxonomy, for conceptualizing and studying these harms. To create a taxonomy, we categorized harms from several sources: systematic reviews of screening, other published literature, and informal discussions with clinicians and patients. We used this information to develop an initial taxonomy and vetted it with local and national experts, making revisions as needed. We propose a taxonomy with 4 domains of harm from screening: physical effects, psychological effects, financial strain, and opportunity costs. Harms can occur at any step of the screening cascade. We provide definitions for each harm domain and illustrate the taxonomy using the example of screening for lung cancer. The taxonomy provides a systematic way to conceptualize harms as experienced by patients. As shown in the lung cancer screening example, the taxonomy also makes clear where (which domains of harms and which parts of the screening cascade) we have useful information and where there are gaps in our knowledge. The taxonomy needs further testing and validation across a broad range of screening programs. We hope that further development of this taxonomy can improve our thinking about the harms of screening, thus informing our research, policy making, and decision making with patients about the wisdom of screening.

Screening over many years is required to optimize reductions in colorectal cancer (CRC) mortality. However, no prior trials have compared strategies for obtaining long-term adherence. Systems of Support to Increase Colorectal Cancer Screening and Follow-Up was implemented in an integrated health care organization in Washington State. Between 2008 and 2009, 4675 individuals aged 50 to 74 years were randomized to receive the usual care (UC), which included clinic-based strategies to increase CRC screening (arm 1), or, in years 1 and 2, mailings with a call-in number for colonoscopy and mailed fecal tests (arm 2), mailings plus brief telephone assistance (arm 3), or mailings and assistance plus nurse navigation (arm 4). Active-intervention subjects (those in arms 2, 3, and 4 combined) who were still eligible for CRC screening were randomized to mailings being stopped or continued in years 3 and 5. The time in compliance with CRC screening over 5 years was compared for persons assigned to any intervention and persons assigned to UC. Screening tests contributed time on the basis of national guidelines for screening intervals (fecal tests annually, sigmoidoscopy every 5 years, and colonoscopy every 10 years). All participants contributed data, but they were censored at disenrollment, death, the age of 76 years, or a diagnosis of CRC. Compared with UC participants, intervention participants had 31% more adjusted covered time over 5 years (incidence rate ratio, 1.31; 95% confidence interval, 1.25-1.37; covered time, 47.5% vs 62.1%). Fecal testing accounted for almost all additional covered time. In a health care organization with clinic-based activities to increase CRC screening, a centralized program led to increased CRC screening adherence over 5 years. Longer term data on screening adherence and its impact on CRC outcomes are needed. Cancer 2017;123:4472-80. © 2017 American Cancer Society. © 2017 American Cancer Society.

The incidence of skin cancer is increasing worldwide. For decades, opportunistic melanoma screening has been carried out to respond to this burden. However, despite potential positive effects such as reduced morbidity and mortality, there is still a lack of evidence for feasibility and effectiveness of organized skin cancer screening. The main aim of the project was to evaluate the feasibility of systematic skin cancer screening. In 2003, the Association of Dermatological Prevention was contracted to implement the population-based SCREEN project (Skin Cancer Research to Provide Evidence for Effectiveness of Screening in Northern Germany) in the German state of Schleswig-Holstein. A two-step program addressing malignant melanoma and nonmelanocytic skin cancer was implemented. Citizens (aged ≥ 20 years) with statutory health insurance were eligible for a standardized whole-body examination during the 12-month study period. Cancer registry and mortality data were used to assess first effects. Of 1.88 million eligible citizens, 360,288 participated in SCREEN. The overall population-based participation rate was 19%. A total of 3103 malignant skin tumors were found. On the population level, invasive melanoma incidence increased by 34% during SCREEN. Five years after SCREEN a substantial decrease in melanoma mortality was seen (men: observed 0.79/100,000 and expected 2.00/100,000; women: observed 0.66/100,000 and expected 1.30/100,000). Because of political reasons (resistance as well as lack of support from major German health care stakeholders), it was not possible to conduct a randomized controlled trial. The project showed that large-scale systematic skin cancer screening is feasible and has the potential to reduce skin cancer burden, including mortality. Based on the results of SCREEN, a national statutory skin cancer early detection program was implemented in Germany in 2008. Copyright © 2010 American Academy of Dermatology, Inc.

In 1992 a national breast cancer screening programme was launched in Luxembourg with following characteristics; invitation at 2-yearly interval, 2 views, double reading for women aged between 50 and 64 and since 2001, those aged 65-69 are as well included. From the beginning on, one of the main concern was to respect a rigorous methodology, in accordance with the recommendations of the European Commission. This paper presents the early performance indicators of the years 1999-2002 of the "Programme Mammographie". Almost all histopathological results were obtained, because only one national pathology laboratory exists in Luxembourg, where also the national tumor's register is located. In ten years, a total of 91.432 mammograms were performed. The results of the early performance indicators are in agreement with the European Recommendations. A 36% detection rate of small size cancers, < or = 10 mm, and since 2000, more then 70% of node negative cancers are observed among women aged 50-64 attending the Programme. The cancer rate with a good prognostic factor for the patients is high. Despite good results, the rate of interval cancers is still too high, and two conclusions can be drown: the women's participation at screening has to be steady in time without trespassing a two years intervals, and after the detection of small cancer a high quality assessment should be followed by an adequate treatment, leading to a reduction of mortality and also to a decrease of morbidity by treatment.

The high prevalence of childhood obesity underscores the importance of monitoring population trends in children's activity and screen time, and describing associations with child age, gender, race/ethnicity, and weight status. Our objective was to estimate the proportion of young children in the US who have low levels of active play or high levels of screen time, or who have both these behaviors, and to describe associations with age, gender, race/ethnicity, and weight status. We analyzed data collected during the National Health and Nutrition Examination Surveys 2001-2004, a US nationally representative cross-sectional study. We studied 2964 children aged 4.00 to 11.99 years. Our main outcomes were reported weekly times that the child played or exercised hard enough to sweat or breathe hard (active play), daily hours the child watched television/videos, used computers, or played computer games (screen time), and the combination of low active play and high screen time. Low active play was defined as active play 6 times or less per week. High screen time was defined as more than 2 hours per day. We accounted for the complex survey design in analyses and report proportions and 95% confidence intervals. We used Wald Chi-square to test for differences between proportions. To identify factors associated with low active play and high screen time, we used multivariate logistic regression. Of US children aged 4 to 11 years, 37.3% (95% confidence interval, 34.1% to 40.4%) had low levels of active play, 65.0% (95% CI, 61.4% to 68.5%) had high screen time, and 26.3% (95% CI, 23.8% to 28.9%) had both these behaviors. Characteristics associated with a higher probability of simultaneously having low active play and high screen time were older age, female gender, non-Hispanic black race/ethnicity, and having a BMI-for-age > or =95th percentile of the CDC growth reference. Many young children in the US are reported to have physical activity and screen time behaviors that are inconsistent with recommendations for healthy pediatric development. Children who are overweight, approaching adolescence, girls, and non-Hispanic blacks may benefit most from public health policies and programs aimed at these behaviors.

Objective: To explore the sustainability of cancer screening strategy from potential demander's perspective in Chinese country, we conducted a study on the use of cancer screening services and willingness-to-pay among the urban community residents. All the participants of this study had not been on the Cancer Screening Program in Urban China (CanSPUC) or any other national level cancer screening projects. Methods: Target communities and populations were selected from the 16 project provinces in China which were on the program between 2014 and 2015, by using the multi-center cross-sectional convenience sampling method. Chi-square was used to compare the rates on the utilization of service and willingness-to-pay across the different subgroups. Logistic progression was conducted to examine factors that associated with the service utilization and willingness-to-pay. Results: A total of 16 394 participants were included in this study. Among them, 12.1% (1 984/16 394) had ever been on a cancer screening program. Populations with following characteristics as: being elderly (60-69 years, OR =1.27, 95% CI : 1.13-1.43), female (male, OR = 0.56, 95% CI : 0.50-0.62), having had higher education (high school/specialized secondary school, OR = 1.51, 95% CI : 1.35-1.70; college or over, OR =2.10, 95% CI : 1.36-3.25), working for public ( OR =2.85, 95% CI : 2.26-3.59), enterprises or self-employed agencies ( OR =1.32, 95% CI : 1.06-1.64), having higher income (60 000-150 000 Chinese Yuan, OR =1.55, 95% CI : 1.39-1.73; ≥150 000 Chinese Yuan, OR =2.57, 95% CI : 2.09-3.15), under basic medical insurance programs for urban employees/for government servants'( OR =1.15, 95% CI : 1.01-1.32), on basic medical insurance set for urban residents'/on commercial medical insurance programs etc . ( OR =1.01, 95% CI : 0.84-1.22), were in favor of the services. When neglecting the fee for charge, 65.8% (10 795/16 394) of the participants said that they could accept the cancer screening program, particularly in those who had already been on the screening program ( P <0.05). 61.2% (10 038/16 392) of all the participants showed the willingness-topay for a long-term packaging screening services, particularly in those who were relatively younger (60-69 years, OR =0.80, 95% CI : 0.74-0.87), working for public ( OR =1.76, 95% CI : 1.56-1.98) or enterprise sectors or self-employed households ( OR =1.32, 95% CI : 1.18-1.47), having higher income (60 000-150 000 Chinese Yuan, OR =1.51, 95% CI : 1.40-1.63; ≥150 000 Chinese Yuan, OR = 1.95, 95% CI : 1.60-2.38), utilized screening services ( OR =2.18, 95% CI : 1.94-2.46). Conclusions: The rate of using the cancer screening services should be improved. Factors including age, gender, education, occupation, income and insurance appeared as major factors related to the use of cancer screening services. Willingness-to-pay seemed relatively high, but the amount of payment they could afford was limited. Factors including age, occupation, income and insurance appeared as major factors to the willingness-to-pay.

To evaluate the results of the Pervasive Developmental Disorders (PDD) screening program currently ongoing in the public health services in the health area of Salamanca and Zamora, Spain, in terms of feasibility, reliability and costs, with the purpose of extending the program at regional and national levels. A total of 54 paediatric teams (nurses and paediatricians) from the provinces of Salamanca and Zamora participated in the training sessions for the PDD Screening Programme in September 2005, and agreed to administer the questionnaire M-CHAT(1) to all parents attending their clinics in any of these two visits: 18 months and/or 24 months within the Well-baby Check-up Program. A total of 9,524 children have participated up to December 2012. Additionally, we evaluated the participation and opinions of the paediatric teams using questionnaires, and costs per positive case have estimated. Out of a total of 852 (8.9%) children determined as PDD high-risk with the M-CHAT questionnaire results, 61 (7.1%) were confirmed as positive with the M-CHAT follow-up interview. Of these, 22 were diagnosed with a PDD and 31 other disorders of childhood onset according to DSM-IV-TR(2). Almost three-quarters (74%) of respondents felt the program was totally feasible, and 22% viable, but with reservations (n=54). This study has been able to show for the first time in Spain, the feasibility of a population-based PDD screening program within the public health system. Training in social and communicative development, and dissemination of the early signs of PDD among paediatricians, as well as the use of the M-CHAT, is essential for progress in the early detection of these disorders.

China has a high burden of cervical cancer (CC) and wide disparities in CC burden exist among different socio-economic regions. In order to reduce these disparities, China's government launched the National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in 2009. Understanding the factors associated with underutilization of CC screening among target populations is important to improve the screening participation rate, and a high participation rate is key to achieving the goals of a screening program. However, data on the knowledge of CC among target populations in program areas is lacking in China. This study will investigate the knowledge of CC prevention and control among women in specific project counties to develop a better understanding of factors that might influence CC screening participation in order to improve the implementation of the NCCSPRA. A cross-sectional survey was conducted and face-to-face interview questionnaires were completed by 308 women who received CC screening services in 6 project counties of NCCSPRA across different socio-economic regions of China. ANOVA and Chi-square tests were used to compare the knowledge rates and scores across the different subgroups. Logistic regression was conducted to examine factors associated with knowledge level. The overall CC knowledge rate of the target population was only 19.5%. Regional socio-economic level, advice from doctors, age, and educational status were strong predictors of knowledge level of CC screening. Significantly lower knowledge rates and scores were identified in older women (55-64 years old), less educated women (with primary school or illiterate), women in less developed regions and women who did not receive any advice about screening results from doctors. The knowledge of CC screening among women in the project counties of NCCSPRA was found to be very poor. Given the importance of knowledge in encouraging women to participate in screening is key to reducing CC burden in rural women in China, it is urgent that a targeted health promotion intervention is developed and implemented in project counties, especially targeting older women, women with less education and women in less developed regions, and focus on improving their CC knowledge and encouraging them to communicate with health care providers. The health promotion intervention targeting health care providers is also important to improve their knowledge of CC and provide best advice to women.

A retrospective clinical audit was performed to assess if the British HIV Association 2011 guidelines on routine screening for tuberculosis in HIV are being implemented in a large UK urban clinic, and if a tuberculosis-screening prompt on the electronic patient record for new attendees was effective. Of 4658 patients attending during the inclusion period, 385 were newly diagnosed first-time attendees and routine tuberculosis screening was recommended in 165. Of these, only 6.1% of patients had a completed tuberculosis screening prompt, and 12.1% underwent routine tuberculosis screening. This audit represents the first published UK data on routine screening rates for tuberculosis in HIV and demonstrates low rates of tuberculosis screening despite an electronic screening prompt designed to simplify adherence to the national guideline. Reasons why tuberculosis screening rates were low, and the prompt ineffective, are unclear. A national audit is ongoing, and we await the results to see if our data reflect a lack of routine tuberculosis screening in HIV-infected patients at a national level. © The Author(s) 2016.

Cardiovascular burden and percutaneous interventions in Russian Federation: systematic epidemiological update

2017-01-01

The situation with cardiovascular (CV) burden in Russian population is alerting, and becomes of interest due to high CV mortality, and shorter lifespan if compare with the Western society amid the absence of the established monitoring or screening system for major CV risk factors. The purpose of this systematic epidemiological update was to explore CV burden in Russia. The study represents pooled results with a systematic epidemiological review of the national mass screening, selected randomized clinical trials and statistical datasets of the national public health CV institutions exploring the trends of the CV burden in all 83 regions of Russia. We overviewed data from a number of the available Russian-speaking national data sources of 2001–2014, and NANOM-FIM trial (NCT01270139) as the only available real-world population study. The CV diseases in Russia accounted for 54.9% of all deaths in 2011–2014. The death rate was 13.3 per 1,000 citizens with CV mortality of 653.9 per 100,000. The life expectancy achieves 64.3 years for male and 76.1 years for female. The mean age of pts in trial was 51.6 years (77.2% males). A total of 175 Russian PCI centers implemented 205,902 angio a year, and 75,378 PCI achieving 531 PCI per 1,000,000 with placement of 101,451 stents (1.37 stents per PCI; 48,057 DES). The smoking (17.3% of screened with a 2,786 cigarettes a year; 70.6% in trial), excessive alcohol consumption (1.8% of screened with a 11.6 L per year; 50.6% in trial), unhealthy Russian diet (abundance of carbohydrates/sugar, saturated and trans fats in 24.3% of screened), psychosocial factors (20%) and physical inactivity (19.6% of screened) remain the major modifiable risk factors. They, in turn, affect such risk factors as dyslipidemia (86.7% in trial), obesity (16.7% of screened; BMI in trial was 28.4), and hypertension (40.8% suffered; 86.1% in trial). CV mortality was not directly associated with a level of poverty (r=0.26, P=0.02) or socio-economic development (P>0.05) in regions. The documented 27% 10-year decline of CV mortality was interpreted as a success of the national policy. Mortality statistics show the stark reality of a high CV burden in Russia. New national program and aggressive emerging efforts are required to tackle CV diseases in Russia. PMID:28164014

Lung cancer is the largest contributor to mortality from cancer. The National Lung Screening Trial (NLST) showed that screening with low-dose helical computed tomography (CT) rather than with chest radiography reduced mortality from lung cancer. We describe the screening, diagnosis, and limited treatment results from the initial round of screening in the NLST to inform and improve lung-cancer-screening programs. At 33 U.S. centers, from August 2002 through April 2004, we enrolled asymptomatic participants, 55 to 74 years of age, with a history of at least 30 pack-years of smoking. The participants were randomly assigned to undergo annual screening, with the use of either low-dose CT or chest radiography, for 3 years. Nodules or other suspicious findings were classified as positive results. This article reports findings from the initial screening examination. A total of 53,439 eligible participants were randomly assigned to a study group (26,715 to low-dose CT and 26,724 to chest radiography); 26,309 participants (98.5%) and 26,035 (97.4%), respectively, underwent screening. A total of 7191 participants (27.3%) in the low-dose CT group and 2387 (9.2%) in the radiography group had a positive screening result; in the respective groups, 6369 participants (90.4%) and 2176 (92.7%) had at least one follow-up diagnostic procedure, including imaging in 5717 (81.1%) and 2010 (85.6%) and surgery in 297 (4.2%) and 121 (5.2%). Lung cancer was diagnosed in 292 participants (1.1%) in the low-dose CT group versus 190 (0.7%) in the radiography group (stage 1 in 158 vs. 70 participants and stage IIB to IV in 120 vs. 112). Sensitivity and specificity were 93.8% and 73.4% for low-dose CT and 73.5% and 91.3% for chest radiography, respectively. The NLST initial screening results are consistent with the existing literature on screening by means of low-dose CT and chest radiography, suggesting that a reduction in mortality from lung cancer is achievable at U.S. screening centers that have staff experienced in chest CT.

Objective There is an increase in the incidence of cancer, and consequently in mortality rates, both in the world and in Turkey. The increase in the incidence and mortality rate of cancer are more prominent in our country as well as in other developing countries. The aim of this workshop was to determine the current status on prevention, screening, early diagnosis and treatment of cancer in our country, to identify related shortcomings, specify solutions and to share these with health system operators, and to aid in implementation of these systems. Developments on palliative care were also evaluated. Materials and Methods The current situation in the practice of clinical oncology, related drawbacks, problems encountered during multidisciplinary approach and their solutions were discussed under several sub-headings during a 3-day meeting organized by the Turkish Ministry of Health (Türkiye Cumhuriyeti Sağlık Bakanlığı-TCSB) with participation of 16 scientists from Turkey and 6 from abroad, and the conclusions were reported. Results It is expected that the newly established Turkish Health Institutes Association (Türkiye Sağlık Enstitüleri Başkanlığı-TÜSEB) and the National Cancer Institute (Ulusal Kanser Enstitüsü) will provide a new framework in the field of oncology. The current positive findings include the increase in the number of scientists who carry out successful trials in oncology both in Turkey and abroad, the implementation of the national cancer registry program by the Cancer Control Department and the breast cancer registry program by the Turkish Federation of Breast Diseases Societies (Türkiye Meme Hastalıkları Dernekleri Federasyonu-TMHDF), and introduction of Cancer Early Diagnosis, Screening, and Training Centers (Kanser Erken Tanı, Tarama ve Eğitim Merkezi-KETEM) for the application of community-based cancer screening programs. In addition to these, obvious shortcomings related to education, implementation, management and research issues were also determined, and policy and project proposals to address these issues were presented. Collaboration with relevant organizations in the implementation of these studies was supported. Conclusion Both the incidence and mortality rates of cancer are increasing in Turkey. The widespread deficiencies in population-based screening and in effective treatment lead to an increase in delay in diagnosis and mortality. Despite improvements in data recording, screening and treatment over the last 10 years, extensive, organized, population-based screening programs and fully equipped early diagnosis and treatment centers are required. Enhancement of basic cancer epidemiologic, translational, genetic and molecular research studies is essential in our country. Improvements on pain treatment and palliative care of patients with chronic and terminal cancer are also required. PMID:28331725

To describe national and regional indicators of process and outcome of breast cancer screening programs in Spain. Overall results and broken down by regions are studied for the period 2007-2008. Outcome indicators (participation, cancer detection rate and characteristics of tumors detected) and process indicators (and intermediate mammograms), classified by types of women screened (initial and consequent regular and irregular) and age groups, are analyzed. Results are compared with reference values established in the European Guidelines. Breast cancer screening coverage is 100% in the country. The overall participation was 69.68% with an adherence of 91.35%. Further assessments of any procedure were performed in 4.93% and invasive further assessments in 0.66%. Intermediate mammograms were indicated in 3.56%. The detection rate was 3.49‰ (5.35‰ age-adjusted); 14.29% of the tumors were intraductal. The 29.49% of the invasive tumors were≤1cm in diameter with 62.22% showing no axillary lymph node involvement. Despite the variability evident in the data provided by the different autonomous communities and the need to improve the homogeneity of information systems as a whole, the assessed indicators meet the standards specified in the European guidelines.

The Cervical and Breast Cancer Prevention (CECAP) Project sought to develop a national model for cervical cancer prevention in Indonesia based on visual inspection with acetic acid (VIA) to detect abnormal changes in the cervix. The purpose of this study was to evaluate a pilot project introducing VIA and cryotherapy in Indonesia and to identify lessons learned that could be applied to the national scale-up of cervical cancer prevention services. Fifty-four months (July 2007 to December 2011) of service records at 17 health centers were abstracted and analyzed. The data were used to calculate the proportion of all women aged 30-50 who received VIA screening, the VIA-positive rate, the treatment rate, and the interval between screening and treatment. The 45 050 women screened during the project included 24.4% of the total female population in the target age group in the catchment area. Throughout the 5-year project, 83.1% of VIA-positive women sought cryotherapy. During the last 18 months of the project, after data collection tools were revised to more accurately reflect when cryotherapy was received, 13% of women were treated on the same day that they were screened. Among the 74% of women treated within 1 month of screening, the mean interval between screening and treatment was 7.2 days. As cervical cancer prevention services are scaled up throughout Indonesia, changes in the service delivery model and program management are needed to increase screening coverage, promote a single-visit approach, and ensure the quality of services. © 2013 The Authors.

An innovative public education tool, called Women's Health Lotería (WHL), was created to promote cervical cancer awareness among Hispanic females. The tool covers the risk factors for cervical cancer, the American Cancer Society (ACS) cervical cancer screening guidelines, and the invasive cervical cancer incidence rate in the Hispanic population. Professional journals and books; ACS and National Cancer Institute literature. Scientific evidence strongly suggests that cervical cancer mortality descreases with regular Pap test screening for sexually active women or those who have reached age 18. Many Hispanic women, however, do not know about the importance of Pap testing. WHL was developed to meet this learning need. After attending the educational program, 87% of the respondents achieved the learning objectives. This educational program can be used to educate Hispanic women about cervical cancer. The content and principles also can be applied to other groups of women.

Electromagnetic Navigational Bronchoscopy

Port, Jeffrey; Harrison, Sebron

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.

Ethical issues evolving from patients’ perspectives on compulsory screening for syphilis and voluntary screening for cervical cancer in Kenya

PubMed Central

2014-01-01

Background Public health aims to provide universal safety and progressive opportunities to populations to realise their highest level of health through prevention of disease, its progression or transmission. Screening asymptomatic individuals to detect early unapparent conditions is an important public health intervention strategy. It may be designed to be compulsory or voluntary depending on the epidemiological characteristics of the disease. Integrated screening, including for both syphilis and cancer of the cervix, is a core component of the national reproductive health program in Kenya. Screening for syphilis is compulsory while it is voluntary for cervical cancer. Participants’ perspectives of either form of screening approach provide the necessary contextual information that clarifies mundane community concerns. Methods Focus group discussions with female clients screened for syphilis and cancer of the cervix were conducted to elicit their perspectives of compulsory and voluntary screening. The discussions were audiotaped, transcribed and thematic content analysis performed manually to explore emerging ethics issues. Results The results indicate that real ethical challenges exist in either of the approaches. Also, participants were more concerned about the benefits of the procedure and whether their dignity is respected than the compulsoriness of screening per se. The implication is for the policy makers to clarify in the guidelines how to manage ethical challenges, while at the operational level, providers need to be judicious to minimize potential harms participants and families when screening for disease in women. Conclusions The context for mounting screening as a public health intervention and attendant ethical issues may be more complex than hitherto perceived. Interpreting emerging ethics issues in screening requires more nuanced considerations of individuals’ contextual experiences since these may be contradictory to the policy position. In considering mounting screening for Syphilis and cervical cancer as a public heal intervention, the community interests and perspectives should be inculcated into the program. Population lack of information on procedures may influence adversely the demand for screening services by the individuals at risk or the community as a collective agent. PMID:24678613

Over 300,000 infants are born annually with sickle cell anemia (SCA) in sub-Saharan Africa, and >50% die young from infection or anemia, usually without diagnosis of SCA. Early identification by newborn screening (NBS), followed by simple interventions dramatically reduced the mortality of SCA in the United States, but this strategy is not yet established in Africa. We designed and implemented a proof-of-principle NBS and treatment program for SCA in Angola, with focus on capacity building and local ownership. Dried bloodspots from newborns were collected from five birthing centers. Hemoglobin identification was performed using isoelectric focusing; samples with abnormal hemoglobin patterns were analyzed by capillary electrophoresis. Infants with abnormal FS or FSC patterns were enrolled in a newborn clinic to initiate penicillin prophylaxis and receive education, pneumococcal immunization, and insecticide-treated bed nets. A total of 36,453 infants were screened with 77.31% FA, 21.03% FAS, 1.51% FS, and 0.019% FSC. A majority (54.3%) of affected infants were successfully contacted and brought to clinical care. Compliance in the newborn clinic was excellent (96.6%). Calculated first-year mortality rate for babies with SCA compares favorably to the national infant mortality rate (6.8 vs. 9.8%). The SCA burden is extremely high in Angola, but NBS is feasible. Capacity building and training provide local healthcare workers with skills needed for a functional screening program and clinic. Contact and retrieval of all affected SCA infants remains a challenge, but families are compliant with clinic appointments and treatment. Early mortality data suggest screening and early preventive care saves lives. Copyright © 2013 Wiley Periodicals, Inc.

Research in the community setting is essential for the translation of advances in cancer research into practice and improving cancer care for all populations. The National Cancer Institute is proposing a new community-based program, NCI Community Oncology Research Program (NCORP), which is the alignment of two existing programs, the Community Clinical Oncology Program, Minority-Based Community Clinical Oncology Program, and their Research Bases, and the National Cancer Institute's Community Cancer Centers Program. NCROP will support cancer control, prevention, treatment, and screening clinical trials and expand its research scope to include cancer care delivery research. Cancer disparities research will be integrated into studies across the continuum of NCORP research. Input from current NCI-funded community investigators provides critical insight into the challenges faced by oncology practices within various organizational structures. Furthermore, these investigators identify the resources, both administrative and clinical, that will be required in the community setting to support cancer care delivery research and to meet the requirements for a new generation of clinical research. The American Society for Clinical Oncology (ASCO) has initiated a forum to focus on the conduct of clinical research in the community setting. Resources are being developed to help practices in managing cancer care in community settings.

Risk-Based Immunization Policies and Tuberculosis Screening Practices for Animal Care and Research Workers in the United States: Survey Results and Recommendations

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.

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.

Australian immunisation registers: established foundations and opportunities for improvement.

The National Immunisation Program Schedule in Australia is formulated and funded nationally under the population-wide Medicare system. The policy is implemented by the eight state and territory jurisdictions. The national immunisation registers consist of the Australian Childhood Immunisation Register (ACIR), and, more recently, the National Human Papillomavirus (HPV) Vaccination Program Register. Moreover, a variety of jurisdiction-based registers and primary care practice software systems exist, which interact with the national registers. General practitioners can obtain reports listing patients under seven years attending their practice and recorded as 'not fully immunised', and immunisation coverage rates for their practice linked to government incentives through Medicare. A 2011 report documents national coverage of 91.8% fully immunised at 12 months, and 92.6% at 24 months. The HPV register provides information on vaccination coverage with the potential to link with a register of cervical cancer screening results. Limitations of current national register include inability to easily access immunisation histories beyond seven years of age, and issues of underreporting and timeliness, which impact significantly the immunisation coverage estimates. The linkage of these registers with healthcare outcome data will further enhance public health outcomes by enabling rapid, population-level vaccine safety and effectiveness investigations in a nation with a track record as an 'early adopter' of new childhood vaccines.

This study aims to compare breast cancer screening (BCS) and cervical cancer screening (CCS) practices of French women born to French parents with those of immigrants and nationals born to immigrants, taking their socioeconomic status into account. The study is based on data collected in 2010 in the Paris metropolitan area among a representative sample of 3000 French-speaking adults. For women with no history of breast or cervical cancer, multivariate logistic regressions and structural equation models were used to investigate the factors associated with never having undergone BCS or CCS. We confirmed the existence of a strong gradient, with respect to migration origin, for delaying or never having undergone BCS or CCS. Thus, being a foreign immigrant or being French of immigrant parentage were risk factors for delayed and no lifetime screening. Interestingly, we found that this gradient persisted (at least partially) after adjusting for the women's socioeconomic characteristics. Only the level of income seemed to play a mediating role, but only partially. We observed differences between BCS and CCS which suggest that organized CCS could be effective in reducing socioeconomic and/or ethnic inequities. Socioeconomic status partially explained the screening nonparticipation on the part of French women of immigrant origin and foreign immigrants. This was more so the case with CCS than with BCS, which suggests that organized prevention programs might reduce social inequalities.

The Italian national health system provides screening to detect breast, colorecatal and cervical cancers, however, population adherence is not as high as expected. Smartphones and their applications (apps) could be used as a tool to communicate with the population and to help improve adherence. The aim of this study was to analyze the features and functions of smartphone applications aimed at secondary prevention of oncological diseases. In February 2016, we reviewed online app stores, using specific key-words, to search for available apps for cancer screening. We identified 32 apps meeting our inclusion criteria. The most frequent types of app are breast cancer (13/32) and cervical cancer (4/32) screening apps. We also found apps addressing secondary prevention of cancers for which screening is not provided to the Italian population (melanoma, prostate cancer and hepatocellular carcinoma). The most common features are: information providers (22/32), risk calculators (10/32), reminders for appointments and tests (7/32). Only one app has been validated for diagnostic accuracy or utility using established international certification (CE Marking). The results show a large potential for development and utilization of applications in secondary prevention. Despite their potential usefulness, there are also disadvantages such as language barriers (only 2 of 32 apps are in Italian), and the digital divide. Future efforts should focus on improving education regarding approaches to technologies, strengthen national and international regulations and monitoring inequalities in access to services.

Implementation of a generalized screening program for neonatal diseases obeys precise guidelines. The disease must be severe, recognizable at an early stage, accessible to an effective treatment, detected with a non expansive and widely applicable test and it must represent an important health problem. In case of positive results, treatment or prevention shall be offered immediately and any screening program has to be regularly evaluated. There is in France since 1978 a national screening program that depends on a private association ("Association française pour le dépistage et la prévention des handicaps de l'enfant") and is supervised by the "Caisse nationale d'assurance maladie" and the "Direction Générale de la Sante". Presently, five diseases are included in the screening program: phenylketonuria, hypothyroidism, congenital adrenal hyperplasia, cystic fibrosis and sickle cell disease, the latter only in at risk newborns. Toxoplasmosis represents a particular problem because screening takes place only in children of mothers that have not been controlled during their pregnancy or in case of seroconversion. Neonatal screening of phenylketonuria and hypothyrodism is unanimously recommended. That of congenital adrenal hyperplasia is approved in most countries. The cases of sickle cell disease and cystic fibrosis are more complex because: 1) all the children that carry the mutations are not affected with a severe disease; 2) there is no curative treatment; 3) parents given information are made anxious, sometimes wrongly if the disease is mild or asymptomatic. The supporters of the screening insist on the interest of an early diagnosis which makes longer the life time of these children, the possibility for the parents to utilize prenatal screening in case of a future pregnancy, and the information given to the heterozygous carriers following a familial screening. The question is raised of the extension of neonatal screening to other diseases. This is now possible due to technical progresses such as the tandem mass spectrometry that can detect about 50 diseases in an only testing. In addition of its cost and of the difficulty to ensure an efficient organization, increasing the number of the screened diseases will raise ethical problems including how the parents will be informed of an incurable disease or a late-onset disease or an entirely asymptomatic disease. It is unanimously admitted that only mendelian diseases should be detected excluding genetic polymorphisms. Analysis of the present situation suggests the following developments: 1) to actualize the guidelines for deciding of a new neonatal screening; 2) to experiment on a local scale any new screening before its extension to the whole country; 3) to create an evaluation committee including paediatricians and epidemiologists and to evaluate on the long term the future of the children; 4) to precisely define the conditions in which the heterozygous carriers will be informed following a familial investigation; 5) to store in a resource biological centre the blood samples in order to utilize this bank for epidemiology studies.

Iron deficiency anaemia is a common problem in pregnancy despite national recommendations and guidelines for treatment. The aim of this study was to appraise the evidence against the UK National Screening Committee (UKNSC) criteria as to whether a national screening programme could reduce the prevalence of iron deficiency anaemia and/or iron deficiency in pregnancy and improve maternal and fetal outcomes. Search strategies were developed for the Cochrane library, Medline and Embase to identify evidence relevant to UK National Screening Committee (UKNSC) appraisal criteria which cover the natural history of iron deficiency and iron deficiency anaemia, the tests for screening, clinical management and evidence of cost effectiveness. Many studies evaluated haematological outcomes of anaemia, but few analysed clinical consequences. Haemoglobin and ferritin appeared the most suitable screening tests, although future options may follow recent advances in understanding iron homeostasis. The clinical consequences of iron deficiency without anaemia are unknown. Oral and intravenous iron are effective in improving haemoglobin and iron parameters. There have been no trials or economic evaluations of a national screening programme for iron deficiency anaemia in pregnancy. Iron deficiency in pregnancy remains an important problem although effective tests and treatment exist. A national screening programme could be of value for early detection and intervention. However, high quality studies are required to confirm whether this would reduce maternal and infant morbidity and be cost effective.

Objective Declines in cervical cancer incidence and mortality in Canada and in the United States have been widely attributed to the introduction of the Papanicolaou (Pap) test. This article reviews changes in screening and introduction of HPV vaccination. Method Sentinel events in cervical cancer screening and primary prevention through HPV vaccination in the US and Canada are described. Results Despite commonalities, cervical cancer screening and prevention differ between the two countries. Canada has a combination of opportunistic and organized programs at the provincial and territorial level, while the US has opportunistic screening and vaccination systems. In the US, the HPV test along with the Pap test (co-testing) is part of national recommendations for routine cervical cancer screening for women age 30 and older. Co-testing is not being considered anywhere in Canada, but primary HPV testing is currently recommended (but not implemented) in one province in Canada. Conclusion Many prevention strategies are available for cervical cancer. Continued public health efforts should focus on increasing vaccine coverage in the target age groups and cervical cancer screening for women at appropriate intervals. Ongoing evaluation will be needed to ensure appropriate use of health resources, as vaccinated women become eligible for screening. PMID:23402963

Children with sickle cell disease (SCD) benefit from newborn screening, because life-threatening complications can be prevented by pre-symptomatic diagnosis. In Germany, the immigration of people from endemic countries is steadily growing. Comprehensive data about the epidemiology and prevalence of SCD in Germany are however lacking, and SCD is not included in the national newborn screening program. We provide data on the prevalence of SCD in a population from both urban and rural areas in Southwest Germany. Anonymized dried blood spots from 37,838 unselected newborns were analyzed by allele-specific PCR for the HbS mutation. Samples tested positive were subjected to Sanger sequencing of the entire β-globin coding sequence firstly to validate the screening and secondly to identify compound heterozygous SCD patients with other mutations of the β-globin gene. We identified 83 carriers of the sickle cell trait, three compound heterozygous SCD patients (two with sickle cell-β-thalassemia, one with sickle cell-Hb Tianshui) but no homozygous SCD patients. The novel molecular method and strategy for newborn screening for SCD presented here compares favorably in terms of sensitivity (1.0 for homozygous HbS, 0.996 for heterozygous HbS), specificity (0.996), practicability, and costs with conventional biochemical screening. Our results demonstrate a significant prevalence of SCD of approximately 1:12,000 in an unselected urban and rural population in Southwest Germany. Together with previously published even higher results from exclusively urban populations in Berlin and Hamburg, our data provide the basis for the decision on a newborn screening program for SCD in Germany.

Introduction The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides mammograms and diagnostic services for low-income, uninsured women aged 40–64 years. Mammography facilities within the NBCCEDP gradually shifted from plain-film to digital mammography. The purpose of this study is to assess the impact of replacing film with digital mammography on health effects (deaths averted, life-years gained [LYG]), costs (for screening and diagnostics), and number of women reached. Methods NBCCEDP 2010 data and data representative of the program’s target population were used in two established microsimulation models. Models simulated observed screening behavior including different screening intervals (annual, biennial, irregular) and starting ages (40, 50 years) for white, black, and Hispanic women. Model runs were performed in 2012. Results The models predicted 8.0–8.3 LYG per 1,000 film screens for black women, 5.9–7.5 for white women, and 4.0–4.5 for Hispanic women. For all race/ethnicity groups, digital mammography had more LYG than film mammography (2%–4%), but had higher costs (34%–35%). Assuming a fixed budget, 25%–26% fewer women could be served, resulting in 22%–24% fewer LYG if all mammograms were converted to digital. The loss in LYG could be reversed to an 8%–13% increase by only including biennial screening. Conclusions Digital could result in slightly more LYG than film mammography. However, with a fixed budget, fewer women may be served with fewer LYG. Changes in the program, such as only including biennial screening, will increase LYG/screen and could offset the potential decrease in LYG when shifting to digital mammography. PMID:25891052

The current Australian National Cervical Screening Program (NCSP) involves biennial, cytology-based screening of women from the age of 18 years. From December, 2017 this will change to a five-yearly human papilloma virus-based screening commencing at age 25. There is some concern that the new program may delay the opportunistic detection of cervical cancers in women under 25 years. (1) To review all cases of invasive cervical cancer in Queensland women under the age of 25 over the last 28 years. (2) To determine symptoms and screening history prior to diagnosis. A retrospective cohort study was undertaken at the Queensland Centre for Gynaecological Cancer (QCGC) and the Queensland Cancer Registry (QCR) of all women aged between 13 and 25 years diagnosed with cervical cancer in Queensland between 1984 and 2012. Demographic data and symptoms prior to diagnosis were extracted from the QCGC and QCR databases. A total of 56 women aged 13-25, were diagnosed with cervical cancer and treated at the QCGC between 1984 and 2012. The commonest reason for the diagnosis of cancer was investigation of abnormal symptoms (n = 22, 39%) rather than routine Pap smear abnormalities (n = 15, 26%). Consistent with the world literature, there is a very low incidence of cervical cancer in women under 25 years of age, irrespective of the age of commencement of screening, or the screening interval. Our study lends some support to the proposed commencement age of 25 years in the new NCSP. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Anticipating implementation of colorectal cancer screening in The Netherlands: a nation wide survey on endoscopic supply and demand

PubMed Central

2012-01-01

Background Colorectal cancer (CRC) screening requires sufficient endoscopic resources. The present study aims to determine the Dutch endoscopic production and manpower for 2009, evaluate trends since 2004, determine additional workload which would be caused by implementation of a CRC screening program, and inventory colonoscopy rates performed in other European countries. Methods All Dutch endoscopy units (N = 101) were surveyed for manpower and the numbers of endoscopy procedures performed in 2009. Based on calculations in the report issued by the Dutch Health Council, future additional workload caused by faecal immunochemical test (FIT) screening was estimated. The number of colonoscopies performed in Europe was evaluated by a literature search and an email-inquiry. Results Compared to 2004, there was a 24% increase in total endoscopies (N = 505,226 in 2009), and a 64% increase in colonoscopies (N = 191,339 in 2009) in The Netherlands. The number of endoscopists had increased by 4.6% (N = 583 in 2009). Five years after stepwise implementation of FIT-based CRC screening, endoscopic capacity needs to be increased an additional 15%. A lack of published data on the number of endoscopies performed in Europe was found. Based on our email-inquiry, the number of colonoscopies per 100,000 inhabitants ranged from 126 to 3,031 in 15 European countries. Conclusions Over the last years, endoscopic procedures increased markedly in The Netherlands without a corresponding increase in manpower. A FIT-based CRC screening program requires an estimated additional 15% increase in endoscopic procedures. It is very likely that current colonoscopy density varies widely across European countries.

Cancer screening programs have been successful in reducing the incidence and mortality due to cervical cancer. For more than a decade, the human papillomavirus test has been recommended as part of these programs, however, Pap tests is not currently recommended for women 65 years of age who participated adequately in screening programs, continuing with these screening programs is not needed. Screening programs will be different in special populations at greatest risk where tests are frequently needed or use of alternative methods.

Stave, G M; Mignogna, J J; Powell, G S; Hunt, C M

1999-05-01

Hemochromatosis is a common inherited disorder of iron metabolism with significant health consequences for the employed population. Although screening for hemochromatosis has been recommended, workplace screening programs remain uncommon. In the first year of a newly initiated corporate screening program, 1968 employees were tested. The screening algorithm included measurement of serum iron and transferrin and subsequent ferritin levels in those employees with elevated iron/transferrin ratios. Thirteen percent of men and 21% of women had elevated iron/transferrin ratios. Of these, 14 men and 2 women had elevated ferritin levels. Of these 16, three had liver biopsies and all three have hemochromatosis. The cost of the screening program was $27,850. The cost per diagnosis was $9283 and the cost per year of life saved was $928. These costs compare very favorably with other common workplace screening programs. Several barriers to obtaining definitive diagnoses on all patients with a positive screening result were identified; strategies to overcome these barriers would further enhance the cost effectiveness of the program. We conclude that workplace hemochromatosis screening is highly cost effective and should be incorporated into health promotion/disease prevention programs.

Colorectal cancer (CRC) is the second most common newly diagnosed cancer and the second most common cause of death in the European Union (EU). CRC is an enormous health and economic burden. Early detection and prevention have the possibility of reducing this burden significantly. Many cancer-associated deaths can be avoided through early detection by high-quality colorectal screening programs followed by appropriate treatment. Under the auspices of the United European Gastroenterology Federation (UEGF), the European Association for Gastroenterology and Endoscopy, the Hungarian Society of Gastroenterology and the Hungarian College of Gastroenterology, the 'Budapest Declaration' (2011) was an accepted official scientific program during the Hungarian Presidency of the Council of the European Union. The Budapest Declaration follows the Munich Declaration (2001), the Brussels Declaration (2007), the Transatlantic Declaration (2009), the Barcelona Declaration (2010), the written declaration of CRC screening, a joint initiative with European Parliamentarians coordinated by the UEGF, and finally, the 'European Guidelines for Quality Assurance in Colorectal Cancer Screening and Diagnosis'. The 'Budapest Declaration' together with previous declarations aims to urge the national and supranational healthcare decision makers to launch new Europe-wide initiatives to establish high-quality CRC programs to achieve optimal efficiency in CRC screening. In case of implementation of the proposals, actions and conditions recommended, we can achieve that one of the basic principles of the EU - the chance of equal access - be realized in member states with respect to the prevention of CRC and reduction of cancer-related mortality. To better achieve this goal, we propose to establish an UEGF joint committee, with one participant representing each EU member state to coordinate and supervise the implementation of CRC screening.

Although colorectal cancer (CRC) is the second leading cause of cancer death among adults in the US and colonoscopy is efficacious in reducing morbidity and mortality from CRC, screening rates are sub-optimal. Understanding the socioeconomic, cultural, and health care context within which decisions about colonoscopy are made allows physicians to address patients' most salient beliefs and values and other constraints when making screening recommendations. To evaluate the direct and interactive effects of socioeconomics, health care variables, psychological characteristics, and cultural values on colonoscopy use. National survey completed between January-August 2009 in a random sample of African American, white, and Hispanic adults ages 50-75 without cancer (n = 582). Self-reported colonoscopy use. Only 59% of respondents reported having a colonoscopy. The likelihood of colonoscopy increased with having health insurance (OR = 2.82, 95% CI = 1.24, 6.43, p = 0.004), and increasing age (OR = 1.40, 95% CI = 1.11, 1.77, p = 0.001). In addition, respondents with greater self-efficacy were more likely to have a colonoscopy (OR = 2.41, 95% CI = 1.35, 4.29, p = 0.003). Programs that help patients to overcome access and psychological barriers to screening are needed.

Communicating the harms and benefits of thyroid screening is necessary to help individuals decide on whether or not to undergo thyroid cancer screening. This study was conducted to assess changes in thyroid cancer screening intention in response to receiving information about overdiagnosis and to determine factors with the greatest influence thereon. Data were acquired from subjects included in the 2013 Korean National Cancer Screening Survey (KNCSS), a nationwide, population-based, cross-sectional survey. Of the 4,100 respondents in the 2013 KNCSS, women were randomly subsampled and an additional face-to-face interview was conducted. Finally, a total of 586 female subjects were included in this study. Intention to undergo thyroid cancer screening was assessed before and after receiving information on overdiagnosis. Prior awareness of overdiagnosis in thyroid cancer screening was 27.8%. The majority of subjects intended to undergo thyroid cancer screening before and after receiving information on overdiagnosis (87% and 74%, respectively). Only a small number of subjects changed their intention to undergo thyroid cancer screening from positive to negative after receiving information on overdiagnosis. Women of higher education level and Medical Aid Program recipients reported being significantly more likely to change their intention to undergo thyroid cancer screening afterreceiving information on overdiagnosis,whilewomen with stronger beliefs on the efficacy of cancer screening were less likely to change their intention. Women in Korea appeared to be less concerned about overdiagnosis when deciding whether or not to undergo thyroid cancer screening.

Mammogram screening in Chile: Using mixed methods to implement health policy planning at the primary care level

Summary Breast cancer has the highest incidence of all cancers among women in Chile. In 2005, a national health program progressively introduced free mammography screening for women aged 50 and older; however, three years later the rates of compliance with mammographic screening was only 12% in Santiago, the capital city of Chile. This implementation article combines the findings of two previous studies that applied qualitative and quantitative methods to improve mammography screening in an area of Santiago. Socio-cultural and accessibility factors were identified as barriers and facilitators during the qualitative phase of the study and then applied to the design of a quantitative randomized clinical trial. After six months of intervention, 6% of women in the standard care group, 51.8% in the low intensity intervention group, and 70.1% in the high intensity intervention group had undergone a screening mammogram. This review discusses how the utilization of mixed methods research can contribute to the improvement of the implementation of health policies in local communities. PMID:21334897

Assessing long-term success and efficiency is an essential part of evaluating cancer control programs. The mortality-to-incidence ratio (MIR) can serve as an insightful indicator of cancer management outcomes for individual nations. By calculating MIRs for the top five cancers in Organization for Economic Cooperation and Development (OECD) countries, the current study attempted to characterize the outcomes of national cancer management policies according to the health system ranking of each country. The MIRs for the five most burdensome cancers globally (lung, colorectal, prostate, stomach, and breast) were calculated for all 34 OECD countries using 2012 GLOBOCAN incidence and mortality statistics. Health system rankings reported by the World Health Organization in 2000 were updated with relevant information when possible. A linear regression model was created, using MIRs as the dependent variable and health system rankings as the independent variable. The linear relationships between MIRs and health system rankings for the five cancers were significant, with coefficients of determination ranging from 49 to 75% when outliers were excluded. A clear outlier, Korea reported lower-than-predicted MIRs for stomach and colorectal cancer, reflecting its strong national cancer control policies, especially cancer screening. The MIR was found to be a practical measure for evaluating the long-term success of cancer surveillance and the efficacy of cancer control programs, especially cancer screening. Extending the use of MIRs to evaluate other cancers may also prove useful.

Dengue has not reached an endemic status in Taiwan; nevertheless, we have implemented a fever screening program at airports for the early detection of febrile passengers with a dengue infection. This study is intended to assess the performance of the airport screening procedures for dengue infection. We analyzed data from the national surveillance system of the Taiwan Centers for Disease Control. We included the imported dengue cases reported by sentinel airports and clinics as well as the domestic cases from 2007-2010. Approximately 44.9% (95%CI: 35.73-54.13%) of the confirmed imported dengue cases with an apparent symptom (febrile) in the viremic stage were detected via the airport fever screening program, with an estimated positive predictive value of 2.36% (95% CI: 0.96- 3.75%) and a negative predictive value > 99.99%. Fluctuations in the number of the symptomatic imported dengue cases identified in the airports (X) were associated with the total number of imported dengue cases (Y) based on a regression analysis of a biweekly surveillance (i.e., n = 104, R(2)(X:Y) = 0.61, P < 0.005). Additionally, the fluctuating patterns in the cumulative numbers of the imported dengue cases (X) with a 1-2 month lead time (t) was in parallel with that of the domestic dengue cases (Y) based on a consecutive 4-year surveillance (i.e., n = 48, R(2)(X(t-1):Y) = 0.22, R(2)(X(t-2):Y) = 0.31, P < 0.001) from 2007-2010. A moderate sensitivity of detecting dengue at the airports examined in this study indicated some limitations of the fever screening program for the prevention of importation. The screening program could assist in the rapid triage for self-quarantine of some symptomatic dengue cases that were in the viremic stage at the borders and contribute to active sentinel surveillance; however, the blocking of viral transmission to susceptible populations (neighbors or family) from all of the viremic travelers, including those with or without symptoms, is critical to prevent dengue epidemics. Therefore, the reinforcement of mosquito bite prevention and household vector control in dengue-endemic or dengue-competent hotspots during an epidemic season is essential and highly recommended.

Latin America and the Caribbean (LAC) have a significant burden of cervical cancer. Prophylactic human papillomavirus (HPV) vaccines are an opportunity for primary prevention and new screening methods, such as new HPV DNA testing, are promising alternatives to cytology screening that should be analyzed in the context of regional preventive programs. Cytology-based screening programs have not fulfilled their expectations and coverage does not sufficiently explain the lack of impact on screening in LAC. While improved evaluation of screening programs is necessary to increase the impact of screening on the reduction of incidence and mortality, other programmatic aspects will need to be addressed such as follow-up of positive tests and quality control. The implementation of new technologies might enhance screening performance and reduce mortality in the region. The characteristics, performance and impact of cervical cancer screening programs in LAC are reviewed in this article.

To describe phase 1 of an organized cytology screening project initiated in Thailand by the Ministry of Public Health and the National Health Security Office. Women aged 35-60 years were encouraged to undergo cervical screening in primary care units and hospitals through awareness programs. Papanicolaou smears were processed and reported at district or provincial cytology laboratories. Women with normal test results were advised to undergo repeat screening after 5 years, while those with precancerous and cancerous lesions were referred for colposcopy, biopsy, and treatment. Information on screening, referral, investigations, and therapy were logged in a computer database. Between 2005 and 2009, 69.2% of the 4030833 targeted women were screened. In all, 20991 women had inadequate smears; 27253 had low-grade squamous intraepithelial lesions; 15706 had high-grade squamous intraepithelial lesions; and 2920 had invasive cancers. Information on the management of precancerous lesions was available for only 17.4% of women referred for colposcopy. Although follow-up data on women with positive test results were inadequately documented, the present findings indicate that provision of cytology services through the existing healthcare system is feasible.

In Malaysia, the current cervical cancer screening program, introduced in the 1960s, has been found to be unsuccessful in terms of Pap smear coverage. The aim of this study is to determine providers perceptives on the program and the feasibility of practicing an organized cervical screening program in Malaysia. 11 key informant interviews were conducted with policy makers and health care providers from the Ministry of Health in Malaysia from October 2009 to May 2010. Interviewees' perceptions were explored on current and organized cervical screening program based on their expertise and experience. The results highlighted that the existing cervical screening program in Malaysia faced flaws at all levels that failed to reduce cervical cancer morbidity and mortality. The identified weaknesses were poor acceptance by women, lack of commitment by health care providers, nature of the program, an improper follow-up system, limited resources and other competing needs. Complementarily, all interviewees perceived an organized cervical screening program as an alternative approach both feasible and acceptable by women and government to practice in Malaysia. Better screening coverage depends on an effective screening program that incorporates a behaviour-based strategy. A new program should be focused in the policy-making context to improve screening coverage and to effectively combat cervical cancer.

Colorectal cancer (CRC) has the second highest cancer mortality rate in Australia. The Australian National Bowel Cancer Screening Program (NBCSP) aims to increase early detection of CRC by offering free Faecal Occult Blood Testing (FOBT), although uptake is low for culturally and linguistically diverse (CALD) groups. To present data on trust and mistrust in the NBCSP by population groups with low uptake and thus to highlight areas in need of policy change. A qualitative study was undertaken in South Australia, involving interviews with 94 people from four CALD groups: Greek, Iranian, Anglo-Australian, and Indigenous peoples. Our study highlights the complexities of institutional trust, which involves considerations of trust at interpersonal, local and national levels. In addition, trust and mistrust was found in more abstract systems such as the medical knowledge of doctors to diagnose or treat cancer or the scientific procedures in laboratories to test the FOBTs. The object of institutional (mis)trust differed between cultural groups - Anglo-Australian and Iranian groups indicated a high level of trust in the government, whereas Indigenous participants were much less trusting. The level and nature of trust in the screening process varied between the CALD groups. Addressing program misconceptions, clarifying the FOBT capabilities and involving medical services in collecting and transporting the samples may increase trust in the NBCSP. However, broader and more enduring mistrust in services and institutions may need to be dealt with in order to increase trust and participation. © 2014 John Wiley & Sons Ltd.

Using data from an eating disorders screening initiative conducted in high schools across the United States, we examined the relationship between vomiting frequency and irregular menses in a nonclinical sample of adolescent females. A self-report questionnaire was administered to students from U.S. high schools participating in the National Eating Disorders Screening Program in 2000. The questionnaire included items on frequency of vomiting for weight control in the past 3 months, other eating disorder symptoms, frequency of menses, height, and weight. Multivariable regression analyses were conducted using data from 2791 girls to estimate the risk of irregular menses (defined as menses less often than monthly) associated with vomiting frequency, adjusting for other eating disorder symptoms, weight status, age, race/ethnicity, and school clusters. Girls who vomited to control their weight one to three times per month were one and a half times more likely (risk ratio [RR] = 1.6; 95% confidence interval [CI] = 1.2-2.2), and girls who vomited once per week or more often were more than three times more likely (RR = 3.2; 95% CI = 2.3-4.4), to experience irregular menses than were girls who did not report vomiting for weight control. Vomiting for weight control remained a strong predictor of irregular menses even when overweight and underweight participants were excluded. Our study adds to the evidence that vomiting may have a direct effect on hormonal function in adolescent girls, and that vomiting for weight control may be a particularly deleterious component of eating disorders.

In the past 5 years, new screening protocols have been developed that provide improved cancer screening options for individuals with Li-Fraumeni syndrome (LFS). Very little has been published on the psychosocial impact of these screening protocols. The goals of this study were to determine how participation in screening impacts individuals psychosocially, to examine the benefits and drawbacks of screening, and to evaluate possible barriers to continued screening. We performed a qualitative study consisting of semistructured phone interviews conducted from December 2015 to February 2016 with 20 individuals attending the LFS screening program at MD Anderson Cancer Center. Data analysis showed that benefits of screening include early detection, peace of mind, centralized screening, knowledge providing power, and screening making LFS seem more livable. Perceived drawbacks included logistical issues, difficulty navigating the system, screening being draining, and significant negative emotional reactions such as anxiety, fear, and skepticism. Regardless of the emotions that were present, 100% of participants planned on continuing screening in the program. Our data indicate that the perceived benefits of screening outweigh the drawbacks of screening. Individuals in this screening program appeared to have improved psychosocial well-being because of their access to the screening program.Genet Med advance online publication 16 March 2017.

A goal of the Tox21 program is to transit toxicity testing from traditional in vivo models to in vitro assays that assess how chemicals affect cellular responses and toxicity pathways. A critical contribution of the NIH Chemical Genomics center (NCGC) to the Tox21 program is the implementation of a quantitative high throughput screening (qHTS) approach, using cell- and biochemical-based assays to generate toxicological profiles for thousands of environmental compounds. Here, we evaluated the effect of chemical compounds on mitochondrial membrane potential in HepG2 cells by screening a library of 1,408 compounds provided by the National Toxicology Program (NTP) in a qHTS platform. Compounds were screened over 14 concentrations, and results showed that 91 and 88 compounds disrupted mitochondrial membrane potential after treatment for one or five h, respectively. Seventy-six compounds active at both time points were clustered by structural similarity, producing 11 clusters and 23 singletons. Thirty-eight compounds covering most of the active chemical space were more extensively evaluated. Thirty-six of the 38 compounds were confirmed to disrupt mitochondrial membrane potential using a fluorescence plate reader and 35 were confirmed using a high content imaging approach. Among the 38 compounds, 4 and 6 induced LDH release, a measure of cytotoxicity, at 1 or 5 h, respectively. Compounds were further assessed for mechanism of action (MOA) by measuring changes in oxygen consumption rate, which enabled identification of 20 compounds as uncouplers. This comprehensive approach allows for evaluation of thousands of environmental chemicals for mitochondrial toxicity and identification of possible MOAs. PMID:23895456

Current status of liver diseases in Korea: hepatocellular carcinoma.

Song, Il Han; Kim, Kyung Sik

2009-12-01

Primary liver cancer, most of which is hepatocellular carcinoma (HCC), is the third common leading cancer in Korea. During the last two decades, the incidence rate of primary liver cancer has shown a modest decrease, but its mortality rate has slightly increased. The incidence of HCC, according to age, peaks in the late sixth decade in men and in the early seventh decade in women. Hepatitis B virus (HBV) is the most important risk factor, which represents approximately 70% of all HCC, and hepatitis C virus (HCV) and alcohol are the next in order of major risk factors for the development of HCC in Korea. HBV-associated HCC occurs 10 years earlier than HCV-associated HCC due to a more prolonged exposure to HBV, which is vertically transmitted almost from HBsAg-positive mother in HBV-endemic area. National Cancer Control Institute, which was reorganized in 2005, is now working for several national projects such as National Cancer Registration Program, National R&D Program for Cancer Control and National Cancer Screening Program. International collaboration for the clinico-epidemiologic research would be needed to provide the specific measures for managing HCC in diverse etiologic situations. Finally, the mechanisms of hepatitis virus-associated hepatocellular carcinogenesis might be clarified to provide insights into the advanced therapeutic and preventive approaches for HCC in Korea, where the majority of HCC originate from chronic HBV and HCV infections.

The Office of Technology Development (OTD) of the National Cancer Institute (NCI) is responsible for negotiating Cooperative Research and Development Agreements (CRADAs), whereby the knowledge resulting from NCI investigators' government-sponsored research is developed in collaboration with universities and/or industry into new products of importance for the diagnosis and treatment of cancer and acquired immunodeficiency syndrome (AIDS). The NCI has recently executed a unique 'clinical trials' CRADA and is developing a model agreement based upon it for the development and commercialization of products for the diagnosis and treatment of cancer and AIDS. NCI drug screening, preclinical testing, clinical trials, and AIDS program capabilities form the basis for this new technology development/technology transfer vehicle. NCI's extensive drug screening program and 'designer foods' program serve as potential sources of investigational new drugs (INDs) and cancer preventatives. Collaborations between NCI and pharmaceutical companies having the facilities, experience, and expertise necessary to develop INDs into approved drugs available to the public are being encouraged where the companies have proprietary rights to INDs, or where NCI has proprietary rights to INDs and invites companies to respond to a collaborator announcement published in the Federal Register. The joint efforts of the NCI and the chosen collaborator are designed to generate the data necessary to obtain pharmaceutic regulatory approval from the Food and Drug Administration (FDA) to market the drugs developed, and thereby make them available to health care providers for the diagnosis and treatment of cancer and AIDS.

The Centers for Disease Control and Prevention’s Screen for Life: National Colorectal Cancer Action Campaign (SFL) is one of the longest running national multimedia campaigns to promote colorectal cancer screening. Since its inception in 1999, no study has quantified the benefits and costs of SFL. We modeled the impact of SFL campaign on screening rates, assuming that the effect size would range from 0.5% to 10% of the unscreened population exposed to the campaign in the last 14 years. Given the estimated benefits of the campaign and costs, we calculated the cost per person screened (2012 dollars). We hypothesize that if 0.5% of the population exposed to campaign messages were screened for colorectal cancer, an additional 251,000 previously unscreened individuals would be screened. The average cost of SFL per person screened would be $2.44. On the other hand, if 10% of the population exposed to campaign messages were screened, an additional 5.01 million individuals would be screened. The average cost per person screened would be $0.12. Results indicate that SFL improves screening rates at a relatively low cost per person screened. The findings in this study provide an important starting point and benchmark for future research efforts to determine the benefits and costs of health communication campaigns to promote cancer prevention.

This case report describes the development and implementation of the Train-the-Trainer: Maternal Depression Screening Program (TTT), a novel approach to disseminating perinatal depression screening. We trained screeners according to a standard pyramid scheme of train-the-trainer programs: three experts trained representatives from health care agencies (the TTT trainers), who in turn trained their staff and implemented depression screening at their home agencies. The TTT trainers had little or no prior mental health experience so "enhanced" components were added to ensure thorough instruction. Although TTT was implemented primarily as a services project, we evaluated both the statewide dissemination and the screening rates achieved by TTT programs. Thirty-two social service or health agencies implemented maternal depression screening in 20 counties throughout Iowa; this reached 58.2% of the Iowa population. For the 16 agencies that provided screening data, the average screening rate (number of women screened/number eligible to be screened) for the first 3 months of screening was 73.2%, 80.5% and 79.0%. We compared screening rates of our TTT programs with those of Healthy Start, a program in which screening was established via an intensive consultation model. We found the screening rates in 62.5% of TTT agencies were comparable to those in Healthy Start. Our "enhanced" train-the-trainer method is a promising approach for broadly implementing depression-screening programs in agencies serving pregnant and postpartum women.

We seek to identify and analyze, from a group of participants experienced with HIV screening, the perceived challenges and solutions to the ethical, financial, and legal considerations of emergency department (ED)-based HIV screening. We performed a qualitative analysis of the focus group discussions from the ethical, financial, and legal considerations portion of the inaugural National Emergency Department HIV Testing Consortium conference. Four groups composed of 20 to 25 consortium participants engaged in semistructured, facilitated focus group discussions. The focus group discussions were audiotaped and transcribed. A primary reader identified major themes and subthemes and representative quotes from the transcripts and summarized the discussions. Secondary and tertiary readers reviewed the themes, subthemes, and summaries for accuracy. The focus group discussions centered on the following themes. Ethical considerations included appropriateness of HIV screening in the ED and ethics of key elements of the 2006 Centers for Disease Control and Prevention HIV testing recommendations. Financial considerations included models of payment and support, role of health care insurance, financial ethics and downstream financial burdens, and advocacy approaches. Legal considerations included the adequacy of obtaining consent, partner notification, disclosure of HIV results, difficulties in addressing special populations, failure of not performing universal screening, failure to notify a person of being tested, failure to notify someone of their test results, liability of inaccurate tests, and failure to link to care. This qualitative analysis provides a broadly useful foundation to the ethical, financial, and legal considerations of implementing HIV screening programs in EDs throughout the United States.

2017-01-01

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

1994-12-01

The Forsyth County Cervical Cancer Prevention Project was a 5 year National Cancer Institute-funded community-based public health education program implemented to address the problem of excess mortality from cervical cancer among black women in Forsyth County, North Carolina. The intervention was a community-based public health education program that included mass media, direct education workshops, and provision of education on cervical cancer and screening to health care providers. The intervention was implemented from November 1988 to September 1991. Evaluation of the community intervention used a quasi-experimental design, with Forsyth County, North Carolina, receiving the program and Durham County, North Carolina, serving as the control. Comparison of pre- and post-intervention telephone survey data revealed that, overall, awareness of cervical cancer and the Pap smear increased. Knowledge, attitudes and behaviors showed little change, considering those interviewed in aggregate. Among women defined as high-risk (elderly, low socioeconomic status, public health clinic patients and/or those who do not receive regular care), a significant trend toward greater participation in screening was detected for the 6 month period following the intervention. These results suggest that awareness of cervical cancer can be increased by public health education, but that the additional attention coming to patients through the actions of health care providers and health care delivery systems may supply the additional input needed to produce behavior change.

Prostate cancer is the commonest cancer in men and a major health issue worldwide. Screening for early disease has been available for many years, but there is still no national screening programme established in the United Kingdom. To assess the latest evidence regarding prostate cancer screening and whether it meets the necessary requirements to be established as a national programme for all men. Electronic databases and library catalogues were searched electronically and manual retrieval was performed. Only primary research results were used for the analysis. In recent years, several important randomised controlled trials have produced varied outcomes. In Europe the largest study thus far concluded that screening reduced prostate cancer mortality by 20%. On the contrary, a large American trial found no reduction in mortality after 7-10 years follow-up. Most studies comment on the adverse effects of screening - principally those of overdiagnosis and subsequent overtreatment. Further information about the natural history of prostate cancer and accuracy of screening is needed before a screening programme can be truly justified. In the interim, doctors and patients should discuss the risks, benefits and sequelae of taking part in voluntary screening for prostate cancer.

This study aimed to assess the socioeconomic inequality and determinants of screen time (ST) frequency in Iranian children and adolescents. This nationwide study was conducted as part of a national school-based surveillance program among 36,486 students consisting of 50.79% boys and 74.23% urban inhabitants, aged 6-18 years, living in urban and rural areas of 30 provinces of Iran. Socioeconomic inequality in ST, including the time spent for ST, watching TV and leisure-time working with computer, was assessed across quintiles of SES using concentration index (C) and slope index of inequality (SII). Overall, 36,486 students completed the study (response rate 91.25%). Their mean (SD) age was 12.14 (3.36) years. The national estimation of frequency of ST was 31.66% (95% CI 31.16-32.17) with ascending change from 20.80% (95% CI 19.81-21.82) to 36.66% (95% CI 35.47-37.87) from the first to the last quintal of SES. Estimated C value at national level was positive (0.08), which indicate inequality was in favor of low SES groups. Considering the SII values, at national level [- 0.16 (- 0.39, 0.06)], the absolute difference in ST frequency between the bottom and top of the socioeconomic groups had descending trends. In multivariate logistic regression model, family history of obesity, generalized obesity and age were the main significant determinants of prolonged ST, watching TV, and computer working (P < 0.001). Socioeconomic inequality in ST frequency was in favor of low SES groups. These findings are useful for health policies, better programming and future complementary analyses.

After Pearl Harbor 1941 and the Japanese conquest of the Netherlands East Indies the U.S. were confronted with both a war in the malaria-ridden South Pacific and the loss of the sources of quinine. This situation gave birth to a Cooperative Wartime Program with the participation of national scientific and medical organizations, universities, hospitals, industries, and the Armed Forces. It worked as a flexible system of coordinated and cooperative units subsidized by the U.S. Government. In the course of WWII malaria casualties dropped beyond expectation due to an improved usage of quinacrine (Atebrine) which was based on new knowledge in pharmacokinetics. Furthermore, basic knowledge in malariology was improved, and a mass-screening resulted in new antimalarial drugs, such as chloroquine. The experiences of the Malaria Program were used by one of its chief architects, James A. Shannon, to transform the National Institutes of Health (NIH) into the model medical research institution whose budget for extramural programs also allowed for the nationwide post-war boom of medical research.

An estimated 2 million inhabitants are infected with Chagas disease in Mexico, with highest prevalence coinciding with highest demographic density in the southern half of the country. After vector-borne transmission, Trypanosoma cruzi is principally transmitted to humans via blood transfusion. Despite initiation of serological screening of blood donations or donors for T. cruzi since 1990 in most Latin American countries, Mexico only finally included mandatory serological screening nationwide in official Norms in 2012. Most recent regulatory changes and segmented blood services in Mexico may affect compliance of mandatory screening guidelines. The objective of this study was to calculate the incremental cost-effectiveness ratio for total compliance of current guidelines from both Mexican primary healthcare and regular salaried worker health service institutions: the Secretary of Health and the Mexican Institute for Social Security. We developed a bi-modular model to analyze compliance using a decision tree for the most common screening algorithms for each health institution, and a Markov transition model for the natural history of illness and care. The incremental cost effectiveness ratio based on life-years gained is US$ 383 for the Secretary of Health, while the cost for an additional life-year gained is US$ 463 for the Social Security Institute. The results of the present study suggest that due to incomplete compliance of Mexico's national legislation during 2013 and 2014, the MoH has failed to confirm 15,162 T. cruzi infections, has not prevented 2,347 avoidable infections, and has lost 333,483 life-years. Although there is a vast difference in T. cruzi prevalence between Bolivia and Mexico, Bolivia established mandatory blood screening for T.cruzi in 1996 and until 2002 detected and discarded 11,489 T. cruzi -infected blood units and prevented 2,879 potential infections with their transfusion blood screening program. In the first two years of Mexico's mandated program, the two primary institutions failed to prevent due to incomplete compliance more potential infections than those gained from the first five years of Bolivia's program. Full regulatory compliance should be clearly understood as mandatory for the sake of blood security, and its monitoring and analysis in Mexico should be part of the health authority's responsibility.

Trade-off between benefit and harm is crucial in health screening recommendations. Part II: evidence summaries.

2011-03-01

Evidence on the effectiveness of health screening strategies may be direct (i.e., studies on screening vs. no screening) or indirect (i.e., studies that separately evaluate the screening test[s], the confirmatory test, or the treatment). Critical trade-offs in the balance between harm and benefit for many screening strategies mandate that advocates of health screening adhere to the ethical precepts of nonmaleficence, autonomy, confidentiality, and equity. In our first article, we pointed out five prerequisites to justifying a health screening program: (1) the burden of illness should be high, (2) the screening and confirmatory tests should be accurate, (3) early treatment (or prevention) must be more effective than late treatment, (4) the tests and the treatment(s) must be safe, and (5) the cost of the screening strategy must be commensurate with the potential benefit. As can be gleaned from these criteria, recommendations on screening must be tailored to specific populations. Recommendations in one country, no matter how authoritative, cannot be generalized to apply to all other countries. Although accuracy, effectiveness, and safety data may be global (criteria 2-4), burden of illness and efficiency (criteria 1 and 5) will always vary from country to country. Rather than review various national guidelines, in this last article of our two-part series, we present evidence summaries to illustrate health screening. Our examples were selected to address special issues related to four situations-screening for cancer, risk factors for disease, genetic disorders, and infectious diseases.

General frameworks of the cancer screening process are available, but none directly compare the process in detail across different organ sites. This limits the ability of medical and public health professionals to develop and evaluate coordinated screening programs that apply resources and population management strategies available for one cancer site to other sites. We present a trans-organ conceptual model that incorporates a single screening episode for breast, cervical, and colorectal cancers into a unified framework based on clinical guidelines and protocols; the model concepts could be expanded to other organ sites. The model covers four types of care in the screening process: risk assessment, detection, diagnosis, and treatment. Interfaces between different provider teams (eg, primary care and specialty care), including communication and transfer of responsibility, may occur when transitioning between types of care. Our model highlights across each organ site similarities and differences in steps, interfaces, and transitions in the screening process and documents the conclusion of a screening episode. This model was developed within the National Cancer Institute–funded consortium Population-based Research Optimizing Screening through Personalized Regimens (PROSPR). PROSPR aims to optimize the screening process for breast, cervical, and colorectal cancer and includes seven research centers and a statistical coordinating center. Given current health care reform initiatives in the United States, this conceptual model can facilitate the development of comprehensive quality metrics for cancer screening and promote trans-organ comparative cancer screening research. PROSPR findings will support the design of interventions that improve screening outcomes across multiple cancer sites. PMID:25957378

Background and Objective China has a high burden of cervical cancer (CC) and wide disparities in CC burden exist among different socio-economic regions. In order to reduce these disparities, China’s government launched the National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in 2009. Understanding the factors associated with underutilization of CC screening among target populations is important to improve the screening participation rate, and a high participation rate is key to achieving the goals of a screening program. However, data on the knowledge of CC among target populations in program areas is lacking in China. This study will investigate the knowledge of CC prevention and control among women in specific project counties to develop a better understanding of factors that might influence CC screening participation in order to improve the implementation of the NCCSPRA. Materials and Methods A cross-sectional survey was conducted and face-to-face interview questionnaires were completed by 308 women who received CC screening services in 6 project counties of NCCSPRA across different socio-economic regions of China. ANOVA and Chi-square tests were used to compare the knowledge rates and scores across the different subgroups. Logistic regression was conducted to examine factors associated with knowledge level. Results The overall CC knowledge rate of the target population was only 19.5%. Regional socio-economic level, advice from doctors, age, and educational status were strong predictors of knowledge level of CC screening. Significantly lower knowledge rates and scores were identified in older women (55–64 years old), less educated women (with primary school or illiterate), women in less developed regions and women who did not receive any advice about screening results from doctors. Conclusion The knowledge of CC screening among women in the project counties of NCCSPRA was found to be very poor. Given the importance of knowledge in encouraging women to participate in screening is key to reducing CC burden in rural women in China, it is urgent that a targeted health promotion intervention is developed and implemented in project counties, especially targeting older women, women with less education and women in less developed regions, and focus on improving their CC knowledge and encouraging them to communicate with health care providers. The health promotion intervention targeting health care providers is also important to improve their knowledge of CC and provide best advice to women. PMID:26657110

Purpose The study uses qualitative research to gain a better understanding of what occurs after low-income women receive an abnormal breast screening and the factors that influence their decisions and behavior. A heuristic model is presented for understanding this complexity. Design Qualitative research methods used to elicited social and cultural themes related to breast cancer screening follow-up. Setting Individual telephone interviews were conducted with 16 women with confirmed breast anomaly. Participants Low-income women screened through a national breast cancer early detection program. Method Grounded theory using selective coding was employed to elicit factors that influenced the understanding and follow-up of an abnormal breast screening result. Interviews were digitally recorded, transcribed, and uploaded into NVivo 8, a qualitative management and analysis software package. Results For women (16, or 72% of case management referrals) below 250% of the poverty level, the impact of social and economic inequities creates a psychosocial context underlined by structural and cultural barriers to treatment that forecasts the mechanism that generates differences in health outcomes. The absence of insurance due to underemployment and unemployment and inadequate public infrastructure intensified emotional stress impacting participants’ health decisions. Conclusion The findings that emerged offer explanations of how consistent patterns of social injustice impact treatment decisions in a high-risk vulnerable population that have implications for health promotion research and systems-level program improvement and development.

Dockres: a computer program that analyzes the output of virtual screening of small molecules

PubMed Central

2010-01-01

Background This paper describes a computer program named Dockres that is designed to analyze and summarize results of virtual screening of small molecules. The program is supplemented with utilities that support the screening process. Foremost among these utilities are scripts that run the virtual screening of a chemical library on a large number of processors in parallel. Methods Dockres and some of its supporting utilities are written Fortran-77; other utilities are written as C-shell scripts. They support the parallel execution of the screening. The current implementation of the program handles virtual screening with Autodock-3 and Autodock-4, but can be extended to work with the output of other programs. Results Analysis of virtual screening by Dockres led to both active and selective lead compounds. Conclusions Analysis of virtual screening was facilitated and enhanced by Dockres in both the authors' laboratories as well as laboratories elsewhere. PMID:20205801

Evidence-based information on mammography screening in Austria--reality or more pie in the sky?

Health literacy is gaining increasing importance in prevention and health care. This is the case for patients and for health-care professionals. Information and risk communication should comply with defined criteria and strengthen health literacy as they are a prerequisite for informed decision making. In this study, we analyse the content of the printed information material (brochures and pamphlets) on mammography screening for consumers that were distributed in Austria in 2011. The evaluation of the 11 brochures shows that the content does not comply with the prerequisites for informed decision making. Since the last study - published in 2004 - the situation has only slightly improved. The authors reemphasise the need for a targeted multimodal information campaign. This is particularly important as a systematic national mammography screening program in compliance with the guidelines of the European Commission will be introduced in Austria in 2013. © Georg Thieme Verlag KG Stuttgart · New York.

2002-01-01

Newborn screening programs collectively administer the largest genetic testing initiative in the United States. The redress of grievances is an important mechanism for consumers to provide input into clinical and public health programs. In this study, we evaluated mechanisms for addressing consumer grievances in newborn screening programs. To do this, we surveyed all 50 state plus the District of Columbia newborn screening programs by questionnaire regarding protocols for receipt and redress of problems reported by parents of newborns and ascertained the existence and nature of complaints and how complaints were documented and addressed. Pertinent state and federal legislation and regulation were also reviewed. Six of 49 newborn screening programs reported having formal policies for handling consumer grievances. Four states reported having pertinent legislation or regulation. Thirty-eight of 49 states reported having received complaints from 1993 to 1995. Thirteen of 49 newborn screening programs reported that they actively seek feedback from consumers. Consumer grievances ranged from minor complaints to potentially life-threatening concerns. In general, complaints are managed on an ad hoc basis; formal policies are typically lacking. As newborn screening programs affect a vast number of Americans, a proactive and comprehensive approach, including solicitation of consumer feedback, could benefit both newborn screening programs and the public served by them.

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.

There were significant recruitment challenges specific to the PLCO Cancer Screening Trial. Large numbers of participants were to be randomized from ten catchment areas nationwide within time and budgetary constraints. The eligible population was elderly and had to meet health and behavioral thresholds. Informed consent was required to participate and be randomized to screening for three cancers at periodic clinic visits or to a usual care arm that included no clinical visits. Consenting required special efforts to fully explain the trial and its potential scientific benefit to future patients with potentially no benefits but possible harms to PLCO participants. Participation would include continued follow-up for at least 13 years after randomization. Strong collaborative investments were required by the NCI and screening centers (SCs) to assure timely recruitment and appropriate racial participation. A trial-wide pilot phase tested recruitment and protocol follow through at SCs and produced a vanguard population of 11,406 participants. NCI announced the trial nationally in advance of the pilot and followed with an even more intense collaborative role with SCs for the main phase to facilitate trial-wide efficient and timely recruitment. Special efforts to enhance recruitment in the main phase included centralized and local monitoring of progress, cross-linking SCs to share experiences in problem solving, centralized training, substantial additional funding dedicated to recruitment and retention, including specialized programs for minority recruitment, obtaining national endorsement by the American Cancer Society, launching satellite recruitment and screening centers, including minority focused satellites, and adding a new SC dedicated to minority recruitment.

Screening for breast cancer can result in early detection of malignancies and lives saved. Many employers now offer periodic screening as an employee health benefit, and some have established screening programs in the workplace. This study was performed to identify the employer costs of breast cancer screening in the workplace, referrals for suspicious findings, and initial treatment of malignant disease. Additionally, the costs for these same services, had they been obtained outside of a workplace screening program, were estimated. Data on program components and associated costs for an established employer based breast cancer screening program were obtained. These costs were compared to those among a hypothetical cohort of women not enrolled in the workplace screening program. From 1989 through 1995, 1,416 women participated in the program. Nearly 2,500 screening mammograms and approximately 2,773 clinical breast examinations were performed, resulting in 292 referrals to physicians outside of the program for additional diagnostic procedures and treatment as needed. These referrals resulted in the detection of 12 malignancies: 8 Stage I; 3 Stage II; and 1 Stage III. Mammographic and clinical breast examination screening cost $249,041; referrals resulting in benign disease or no detectable disease cost $185,002; and referrals resulting in malignant disease, followed by initial treatment, cost $148,530. Therefore, the total cost was $582,573. Approximately 47% of the cost of referrals and initial treatment were due to employee lost productivity. Total cost in the hypothetical cohort was $1,067,948 under the assumptions that all women received screening outside of the workplace, and that the same number of malignancies were detected at the same stage as in the workplace program. These findings indicate referrals resulting in detection of benign disease or no disease accounted for a substantial proportion of the total cost of the program. In addition, employee lost productivity accounted for almost 50% of the cost of all referrals and initial treatment. Workplace screening is a relatively efficient approach for early detection of breast cancer when compared to off site screening or no screening. The efficiency could be improved with a reduction in the number and cost of unnecessary referrals.

Objective Thousands of chemicals are in common use, but only a portion of them have undergone significant toxicologic evaluation, leading to the need to prioritize the remainder for targeted testing. To address this issue, the U.S. Environmental Protection Agency (EPA) and other organizations are developing chemical screening and prioritization programs. As part of these efforts, it is important to catalog, from widely dispersed sources, the toxicology information that is available. The main objective of this analysis is to define a list of environmental chemicals that are candidates for the U.S. EPA screening and prioritization process, and to catalog the available toxicology information. Data sources We are developing ACToR (Aggregated Computational Toxicology Resource), which combines information for hundreds of thousands of chemicals from > 200 public sources, including the U.S. EPA, National Institutes of Health, Food and Drug Administration, corresponding agencies in Canada, Europe, and Japan, and academic sources. Data extraction ACToR contains chemical structure information; physical–chemical properties; in vitro assay data; tabular in vivo data; summary toxicology calls (e.g., a statement that a chemical is considered to be a human carcinogen); and links to online toxicology summaries. Here, we use data from ACToR to assess the toxicity data landscape for environmental chemicals. Data synthesis We show results for a set of 9,912 environmental chemicals being considered for analysis as part of the U.S. EPA ToxCast screening and prioritization program. These include high-and medium-production-volume chemicals, pesticide active and inert ingredients, and drinking water contaminants. Conclusions Approximately two-thirds of these chemicals have at least limited toxicity summaries available. About one-quarter have been assessed in at least one highly curated toxicology evaluation database such as the U.S. EPA Toxicology Reference Database, U.S. EPA Integrated Risk Information System, and the National Toxicology Program.

Black smokers have demonstrated greater lung cancer disease burden and poorer smoking cessation outcomes compared with whites. Lung cancer screening represents a unique opportunity to promote cessation among smokers; however, little is known about the differential impact of screening on smoking behaviors among black and white smokers. Using data from the National Lung Screening Trial (NLST), we examined the racial differences in smoking behaviors after screening. We examined racial differences in smoking behavior and cessation activity among 6,316 white and 497 black (median age, 60 and 59 years, respectively) NLST participants who were current smokers at screening using a follow-up survey on 24-hour and 7-day quit attempts, 6-month continuous abstinence, and the use of smoking cessation programs and aids at 12 months after screening. Using multiple regression analyses, we examined the predictors of 24-hour and 7-day quit attempts and 6-month continuous abstinence. At 12 months after screening, blacks were more likely to report a 24-hour (52.7% vs. 41.2%, p < .0001) or 7-day (33.6% vs. 27.2%, p = .002) quit attempt. However, no significant racial differences were found in 6-month continuous abstinence (5.6% blacks vs. 7.2% whites). In multiple regression, black race was predictive of a higher likelihood of a 24-hour (odds ratio [OR], 1.6, 95% confidence interval [CI], 1.2-2.0) and 7-day (OR, 1.5, 95% CI, 1.1-1.8) quit attempt; however, race was not associated with 6-month continuous abstinence. Only a positive screening result for lung cancer was significantly predictive of successful 6-month continuous abstinence (OR, 2.3, 95% CI, 1.8-2.9). Although blacks were more likely than whites to have 24-hour and 7-day quit attempts, the rates of 6-month continuous abstinence did not differ. Targeted interventions are needed at the time of lung cancer screening to promote abstinence among all smokers. Among smokers undergoing screening for lung cancer, blacks were more likely than whites to have 24-hour and 7-day quit attempts; however, these attempts did not translate to increased rates of 6-month continuous abstinence among black smokers. Targeted interventions are needed at the time of lung cancer screening to convert quit attempts to sustained smoking cessation among all smokers. ©AlphaMed Press.

Despite antiretroviral therapy (ART), incident human immunodeficiency virus (HIV) continues to rise, and sexually transmitted infections (STI) are well known for their part in HIV transmission. National guidelines recommend routine STI screening in HIV-positive individuals, but despite this, reported uptake remains low. We implemented a nurse-led self-screening program for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) in asymptomatic HIV patients. Self-collected samples were tested for CT and GC using the GenProbe Aptima Combo 2 assay. Clinical records were reviewed for ART history, CD4 T-cell count, and plasma viral load. A screening service evaluation questionnaire was handed out. During an 8-month period, 976 screens were performed. In all, 143 infections were detected which would have been missed without the screening program. Overall prevalence of infection among men who have sex with men was 17.4%: rectal CT and GC, 9.8% (56/571) and 4.2% (24/571), respectively; urethal CT and GC, 2.6% (16/605) and 1.3% (8/605), respectively; and pharyngeal CT and GC, 1.7% (10/589) and 3.9% (23/589), respectively. Among heterosexual men and women, the rates of CT were 2.1% (3/141) and 1.5% (3/201), and there was no GC. Transient viremia was observed at the time of STI diagnosis in 6 patients on ART. All men who have sex with men and most women found self-swabbing acceptable, and most patients indicated that they would like to be offered testing in future. These findings highlight the need for the introduction of similar screening approaches in HIV clinics. Self-collected specimens using sensitive and specific GC and CT nucleic acid amplification tests are a convenient and acceptable way of testing, and it may address some of the barriers to screening in this population.

The Royal College of Physicians and Surgeons of Canada requires that residents demonstrate competence in health advocacy (HA). We sought to develop and implement a national educational module for obstetrics and gynaecology residents to address the role of HA. This pilot program was centred on cervical cancer prevention, which lends itself to applying the principles of advocacy. An educational module was developed and disseminated to all obstetrics and gynaecology residency programs in Canada. The module describes options for HA involving cervical dysplasia screening, such as an outreach clinic or a forum for public/student education, which were to be implemented during Cervical Cancer Awareness Week. The measures of success were the number of programs implementing the curriculum, number of residents who participated, diversity of projects implemented, individuals (patients or learners) reached by the program, and the overall experience of the trainees. Three programs implemented the curriculum in 2011, one in 2012, and seven in 2013. After three years, the module has involved seven of 16 medical schools, over 100 residents, and thousands of women either directly or indirectly. Additionally, attributes of HA experienced by the residents were identified: teamwork, leadership, increased systems knowledge, increased social capital within the community, creativity, innovation, and adaptability. We have demonstrated that an educational module can be implemented nationally, helping our residents fulfill their HA requirements. Other specialties could use this module in building HA into their own programs.

The International Organization for Migration (IOM) developed and implemented a three-month project entitled Priority Medical Screening of Kosovar Refugees in Macedonia, within the Humanitarian Evacuation Program (HEP) for Kosovar refugees from FR Yugoslavia, which was adopted in May 1999. The project was based on an agreement with the office of United Nations High Commission for Refugees (UNHCR) and comprised the entry of registration data of refugees with medical condition (Priority Medical Database), and classification (Priority Medical Screening) and medical evacuation of refugees (Priority Medical Evacuation) in Macedonia. To realize the Priority Medical Screening project plan, IOM developed and set up a Medical Database linked to IOM/UNHCR HEP database, recruited and trained a four-member data entry team, worked out and set up a referral system for medical cases from the refugee camps, and established and staffed medical contact office for refugees in Skopje and Tetovo. Furthermore, it organized and staffed a mobile medical screening team, developed and implemented the system and criteria for the classification of referred medical cases, continuously registered and classified the incoming medical reports, contacted regularly the national delegates and referred to them the medically prioritized cases asking for acceptance and evacuation, and co-operated and continuously exchanged the information with UNHCR Medical Co-ordination and HEP team. Within the timeframe of the project, 1,032 medical cases were successfully evacuated for medical treatment to 25 host countries throughout the world. IOM found that those refugees suffering from health problems, who at the time of the termination of the program were still in Macedonia and had not been assisted by the project, were not likely to have been priority one cases, whose health problems could be solved only in a third country. The majority of these vulnerable people needed social rather than medical care and assistance a challenge that international aid agencies needed to address in Macedonia and will need to address elsewhere.

Volatile organic compounds in samples from domestic and public wells, 1985-2002

The U.S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program recently completed a national study of volatile organic compounds (VOCs) in the Nation's ground water (Zogorski and others, 2006). Part of this assessment emphasizes the occurrence of 55 VOCs in samples from 2,401 domestic wells and 1,096 public wells during 1985-2002. Samples were collected prior to any treatment or blending of water. Domestic wells are privately owned, self-supplied sources used for drinking water and household use (Moran and others, 2002). Public wells are privately or publicly owned and supply water to public water systems (PWSs). Samples from public wells in this assessment characterize the quality of water captured by wells that supply drinking water to PWSs. These systems supply drinking water to at least 15 service connections or regularly serve at least 25 individuals daily at least 60 days a year (U.S. Environmental Protection Agency, 2005). For a screening-level assessment, VOC concentrations were compared to human-health benchmarks. Concentrations greater than the U.S. Environmental Protection Agency's (USEPA) Maximum Contamination Levels (MCLs) (U.S. Environmental Protection Agency, 2004) or the USGS's Health-Based Screening Levels (HBSLs) (Zogorski and others, 2006) were considered of potential human-health concern. The findings from the well samples provide an important perspective on the quality of the Nation's ground water used for drinking-water supplies. More information about this national assessment of VOCs is available (http://water.usgs.gov/nawqa/vocs/national_assessment).

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.

Breast cancer is the most common cancer in Malaysian females. The National Cancer Registry in 2003 and 2006 reported that the age standardized incidence of breast cancer was 46.2 and 39.3 per 100,000 populations, respectively. With the cumulative risk at 5.0; a woman in Malaysia had a 1 in 20 chance of developing breast cancer in her lifetime. The incidence of cancer in general, and for breast cancer specifically was highest in the Chinese, followed by Indians and Malays. Most of the patients with breast cancers presented at late stages (stage I: 15.45%, stage II: 46.9%, stage III: 22.2% and stage IV: 15.5%). The Healthy Lifestyles Campaign which started in the early nineties had created awareness on breast cancer and after a decade the effort was enhanced with the Breast Health Awareness program to promote breast self examination (BSE) to all women, to perform annual clinical breast examination (CBE) on women above 40 and mammogram on women above 50. The National Health Morbidity Survey in 2006 showed that the prevalence rate of 70.35% by any of three methods of breast screening; 57.1% by BSE, 51.8% by CBE and 7.6% by mammogram. The current screening policy for breast cancer focuses on CBE whereby all women at the age of 20 years and above must undergo breast examination by trained health care providers every 3 years for age between 20-39 years, and annually for age 40 and above. Several breast cancer preventive programs had been developed by various ministries in Malaysia; among which are the RM50 subsidy for mammogram by the Ministry of Women, Family and Community Development and the SIPPS program (a call-recall system for women to do PAP smear and CBE) by the Ministry of Health. Measures to increase uptake of breast cancer screening and factors as to why women with breast cancer present late should be studied to assist in more development of policy on the prevention of breast cancer in Malaysia.

To investigate the awareness of breast cancer (BCa) and BCa screening amongst women at midlife in Bangladesh. A nationally representative cross-sectional survey of women aged 30-59 years was conducted in 7 districts of the 7 divisions in Bangladesh, using a multistage cluster sampling technique. The factors associated with the awareness of BCa and breast assessment of asymptomatic women were investigated separately, using multivariable logistic regression. Of the 1590 participants, mean age 42.3 (±8.0) years, 81.9% had ever heard of BCa and 64.2% of any methods of BCa screening, respectively. Awareness of BCa was associated with being aged 40-49 years (adjusted OR 2.04, 95% CI 1.46-2.84), aged 49-59 years (1.96, 1.32-2.91), being overweight (1.46, 1.07-2.01) and obesity (1.62, 1.01-2.62), while inversely associated with rural dwelling (0.37, 0.22-0.61), primary education (0.44, 0.27-0.70), having no education (0.23, 0.14-0.36) and parity (0.62, 0.44-0.87). Of the 750 women who were aware of clinical breast examination (CBE) or mammography, reasons provided for not undergoing screening included that they had no symptoms (92%) and that they did not know screening was needed (40%). 8% of women reported CBE. Women with no education were less likely to have undergone CBE (0.38, 0.141.04; p=0.059). Lack of understanding of the assessment of asymptomatic women is the key obstacle to BCa screening uptake in Bangladesh. Health education programs, especially BCa awareness programs, have the potential to increase BCa awareness and down-staging of the disease. Copyright © 2015 Elsevier Ireland Ltd.

Lung cancer screening with a low-dose chest CT scan can result in more benefit than harm when performed in settings committed to developing and maintaining high-quality programs. This project aimed to identify the components of screening that should be a part of all lung cancer screening programs. To do so, committees with expertise in lung cancer screening were assembled by the Thoracic Oncology Network of the American College of Chest Physicians (CHEST) and the Thoracic Oncology Assembly of the American Thoracic Society (ATS). Lung cancer program components were derived from evidence-based reviews of lung cancer screening and supplemented by expert opinion. This statement was developed and modified based on iterative feedback of the committees. Nine essential components of a lung cancer screening program were identified. Within these components 21 Policy Statements were developed and translated into criteria that could be used to assess the qualification of a program as a screening facility. Two additional Policy Statements related to the need for multisociety governance of lung cancer screening were developed. High-quality lung cancer screening programs can be developed within the presented framework of nine essential program components outlined by our committees. The statement was developed, reviewed, and formally approved by the leadership of CHEST and the ATS. It was subsequently endorsed by the American Association of Throacic Surgery, American Cancer Society, and the American Society of Preventive Oncology. PMID:25356819

The end of the article features the development of HIV/AIDS diagnosis and its implementation in the Czech Republic. The establishment of the National Reference Laboratory for AIDS (NRL AIDS) at the National Institute of Public Health late in 1985 is mentioned and its responsibilities as the methodology centre in the areas of HIV/AIDS laboratory diagnosis and epidemiology are specified. In cooperation with the respective experts, a pilot HIV/AIDS prevalence study was conducted in the Czech Republic. The general criteria for HIV/AIDS laboratory diagnosis were set for both blood transfusion service and microbiology laboratories. Early in 1987, mass screening of blood donors was introduced in blood transfusion centres and in the second half of the same year, the HIV screening program was extended to selected microbiology laboratories. The NRL AIDS established a unified data reporting system, analyzed the results at the national level, and since 1989, has been reporting the outcomes to the international AIDS, and later HIV/AIDS, reporting system. The NRL AIDS also participated in a number of international projects in the areas of the research and development of laboratory techniques and epidemiological surveillance.

Training research staff to implement clinical trials occurring in community-based addiction treatment programs presents unique challenges. Standardized patient walkthroughs of study procedures may enhance training and protocol implementation. Examine and discuss cross-site and cross-study challenges of participant screening and data collection procedures identified during standardized patient walkthroughs of multi-site clinical trials. Actors portrayed clients and "walked through" study procedures with protocol research staff. The study completed 57 walkthroughs during implementation of 4 clinical trials. Observers and walkthrough participants identified three areas of concern (consent procedures, screening and assessment processes, and protocol implementation) and made suggestions for resolving the concerns. Standardized patient walkthroughs capture issues with study procedures previously unidentified with didactic training or unscripted rehearsals. Clinical trials within the National Drug Abuse Treatment Clinical Trials Network are conducted in addiction treatment centers that vary on multiple dimensions. Based on walkthrough observations, the national protocol team and local site leadership modify standardized operating procedures and resolve cross-site problems prior to recruiting study participants. The standardized patient walkthrough improves consistency across study sites and reduces potential site variation in study outcomes.

As is the case in many developing nations, previous studies of breast cancer screening behavior in Malaysia have used relatively small samples that are not nationally representative, thereby limiting the generalizability of results. Therefore, this study uses nationally representative data from the Malaysia Non-Communicable Disease Surveillance-1 to investigate the role of socio-economic status on breast cancer screening behavior in Malaysia, particularly differences in screening behaviour between ethnic groups. The decisions of 816 women above age 40 in Malaysia to screen for breast cancer using mammography, clinical breast exams (CBE), and breast self-exams (BSE) are modeled using logistic regression. Results indicate that after adjusting for differences in age, education, household income, marital status, and residential location, Malay women are less likely than Chinese and Indian women to utilize mammography, but more likely to perform BSE. Education level and urban residence are positively associated with utilization of each method, but these relationships vary across ethnicity. Higher education levels are strongly related to using each screening method among Chinese women, but have no statistically significant relationship to screening among Malays. © 2011 Wiley Periodicals, Inc.

Worldwide, colorectal cancer is the fourth leading cause of death from cancer and the incidence is projected to increase. Many countries are exploring the introduction of organized screening programs, but there is limited information on the resources required and guidance for cost-effective implementation. To facilitate the generating of the economics evidence base for program implementation, we collected and analyzed detailed program cost data from 5 European members of the International Colorectal Cancer Screening Network. The cost per person screened estimates, often used to compare across programs as an overall measure, varied significantly across the programs. In addition, there were substantial differences in the programmatic and clinical cost incurred, even when the same type of screening test was used. Based on these findings, several recommendations are provided to enhance the underlying methodology and validity of the comparative economic assessments. The recommendations include the need for detailed activity-based cost information, the use of a comprehensive set of effectiveness measures to adequately capture differences between programs, and the incorporation of data from multiple programs in cost-effectiveness models to increase generalizability. Economic evaluation of real-world colorectal cancer-screening programs is essential to derive valuable insights to improve program operations and ensure optimal use of available resources.

Participation of Iranian women with a family history of breast cancer in breast cancer screening programs is low. This study evaluates the compliance of women having a family history of breast cancer with clinical breast exam (CBE) according to the stage of transtheoretical model (TTM) and health belief model (HBM). In this cross-sectional study, we used Persian version of champion's HBM scale to collect factors associated with TTM stages applied to screening from women over 20 years and older. The obtained data were analyzed by SPSS, using descriptive statistics, Chi-square test, independent t -test, and analysis of covariance. Final sample size was 162 women. Thirty-three percent were in action/maintenance stage. Older women, family history of breast cancer in first-degree relatives, personal history of breast disease, insurance coverage, and a history of breast self-examination were associated with action/maintenance stage. Furthermore, women in action/maintenance stages had significantly fewer perceived barriers in terms of CBE in comparison to women in other stages ( P < 0.05). There was no significant difference in other HBM subscales scores between various stages of CBE screening behavior ( P > 0.05). The finding indicates that the rate of women in action/maintenance stage of CBE is low. Moreover, results show a strong association between perceived barriers and having a regular CBE. These clarify the necessity of promoting national target programs for breast cancer screening, which should be considered as the first preference for reducing CBE barriers.

Colorectal cancer screening program using fecal immunochemical test had been conducted on an isolated island named Nii-jima. However, the participation rate of the program had been approximately 12%, which was lower than average level of Japan. This study aimed to evaluate the participation rate, safety and efficacy of a colorectal cancer screening program using colonoscopy on the island. Educational campaigns were actively conducted every month using information bulletins and special propaganda pamphlets. The primary recommended modality was colonoscopy, followed by fecal immunochemical test. The participants of this program were 1671 individuals aged 40–79 years (men, 819; women, 852). A total of 789 (47.2%) individuals provided consent for this screening program, and 89.2% (704/789) of participants chose colonoscopy as the primary screening procedure. The completion rate of total colonoscopy was 99.7%, and there was no complication during this program. Detection rates of invasive cancer, intramucosal cancer, advanced neoplasia and any adenoma were 0.9% (n = 6), 2.4% (n = 17), 11.8% (n = 83) and 50.0% (n = 352), respectively. The adenoma detection rate and incidence of advanced neoplasia were significantly higher in men than in women in all age groups. The colorectal cancer screening program using colonoscopy that was conducted on an island achieved considerably higher participation rate than the conventional screening program using fecal immunochemical test. Completion rate and safety of screening colonoscopy were excellent during this program.

The Botswana workplace wellness program (WWP) for health care workers (HCWs) was initiated in 2007. WWP implementation was assessed using a sequential, explanatory, mixed methods design including a national implementation assessment (27 health districts) and in-depth interviews (n = 38). Level of implementation varied across districts with health screening, therapeutic recreation, and health promotion implemented more frequently than occupational health activities and psychosocial services. Facilitators to WWP implementation included establishment of a dedicated, diverse WWP committee; provision of administrative support, and integration of activities into organizational culture. Barriers included competing priorities related to delivery of health services to clients, limited technical ability to deliver occupation health activities and psychosocial support, receipt of health services from colleagues, and limited appreciation for personal wellness by some HCWs. Ensuring the well-being of HCWs is critical in reaching international health goals. PMID:28742763
