In species that require parental care, each parent can either care for their offspring or leave them in the care of the other parent. For each parent this creates three possible parental care strategies: biparental care, uniparental (male or female) care, and uniparental desertion by either the male or female. The burying beetle, Nicrophorus orbicollis, typically exhibits biparental care of offspring, and thus provides a unique system that allows us to compare the fitness benefits of these parental care strategies in an unconfounded way. In this study, we assess the lifetime fitness of biparental care, uniparental care, and uniparental desertion strategies in both male and female N. orbicollis. Specifically, we tested for increased fitness of the biparental care strategy compared to uniparental care strategies. Second, we test for equality of fitness between uniparental care and uniparental desertion strategies. Surprisingly, biparental care yields lower lifetime fitness for both parents compared to the other two strategies. Also, uniparental care and uniparental desertion strategies yielded equal fitness. The evolution of biparental care in this system is not consistent with the expectation of a mutual fitness benefit. We discuss other potential explanations for the evolution of biparental care in this system.

Laboratory testing in primary care is a fundamental process that supports patient management and care. Any breakdown in the process may alter clinical information gathering and decision-making activities and can lead to medical errors and potential adverse outcomes for patients. Various information technologies are being used in primary care with the goal to support the process, maximize patient benefits and reduce medical errors. However, the overall impact of health information technologies on laboratory testing processes has not been evaluated. To synthesize the positive and negative impacts resulting from the use of health information technology in each phase of the laboratory 'total testing process' in primary care. We conducted a systematic review. Databases including Medline, PubMed, CINAHL, Web of Science and Google Scholar were searched. Studies eligible for inclusion reported empirical data on: 1) the use of a specific IT system, 2) the impacts of the systems to support the laboratory testing process, and were conducted in 3) primary care settings (including ambulatory care and primary care offices). Our final sample consisted of 22 empirical studies which were mapped to a framework that outlines the phases of the laboratory total testing process, focusing on phases where medical errors may occur. Health information technology systems support several phases of the laboratory testing process, from ordering the test to following-up with patients. This is a growing field of research with most studies focusing on the use of information technology during the final phases of the laboratory total testing process. The findings were largely positive. Positive impacts included easier access to test results by primary care providers, reduced turnaround times, and increased prescribed tests based on best practice guidelines. Negative impacts were reported in several studies: paper-based processes employed in parallel to the electronic process increased the potential for medical errors due to clinicians' cognitive overload; systems deemed not reliable or user-friendly hampered clinicians' performance; and organizational issues arose when results tracking relied on the prescribers' memory. The potential of health information technology lies not only in the exchange of health information, but also in knowledge sharing among clinicians. This review has underscored the important role played by cognitive factors, which are critical in the clinician's decision-making, the selection of the most appropriate tests, correct interpretation of the results and efficient interventions. By providing the right information, at the right time to the right clinician, many IT solutions adequately support the laboratory testing process and help primary care clinicians make better decisions. However, several technological and organizational barriers require more attention to fully support the highly fragmented and error-prone process of laboratory testing. Copyright © 2018 Elsevier B.V.

Briefly trained physicians assistants using protocols (clinical algorithms) for diabetes, hypertension, and related chronic arteriosclerotic and hypertensive heart disease abstrated information from the medical record and obtained history and physical examination data on every patient-visit to a city hospital chronic disease clinic over a 18-month period. The care rendered by the protocol system was compared with care rendered by a "traditional" system in the same clinic in which physicians delegated few clinical tasks. Increased thoroughness in collecting clinical data in the protocol system led to an increase in the recognition of new pathology. Outcome criteria reflected equivalent quality of care in both groups. Efficiency time-motion studies demonstrated a 20 per cent saving in physician time with the protocol system. Coct estimates, based on the time spent with patients by various providers and on the laboratory-test-ordering patterns, demonstrated equivalent costs of the two systems, given optimal staffing patterns. Laboratory tests were a major element of the cost of patient care,and the clinical yield per unit cost of different tests varied widely.

Testing a diagnosis-related group index for skilled nursing facilities

1986-01-01

Interest in case-mix measures for use in nursing home payment systems has been stimulated by the Medicare prospective payment system (PPS) for short-term acute-care hospitals. Appropriately matching payment with care needs is important to equitably compensate providers and to encourage them to admit patients who are most in need of nursing home care. The skilled nursing facility (SNF) Medicare benefit covers skilled convalescent or rehabilitative care following a hospital stay. Therefore, it might appear that diagnosis-related groups (DRG's), the basis for patient classification in PPS, could also be used for the Medicare SNF program. In this study, a DRG-based case-mix index (CMI) was developed and tested to determine how well it explains cost differences among SNF's. The results suggest that a DRG-based SNF payment system would be highly problematic. Incentives of this system would appear to discourage placement of patients who require relatively expensive care.

The first part of this manuscript is an introduction to systems engineering and how it may be applied to health care and point of care testing (POCT). Systems engineering is an interdisciplinary field that seeks to better understand and manage changes in complex systems and projects as whole. Systems are sets of interconnected elements which interact with each other, are dynamic, change over time and are subject to complex behaviors. The second part of this paper reports on the results of the National Institute of Biomedical Imaging and Bioengineering (NIBIB) workshop exploring the future of point of care testing and technologies and the recognition that these new technologies do not exist in isolation. That they exist within ecosystems of other technologies and systems; and these systems influence their likelihood of success or failure and their effectiveness. In this workshop, a diverse group of individuals from around the country, from disciplines ranging from clinical care, engineering, regulatory affairs and many others to members of the three major National Institutes of Health (NIH) funded efforts in the areas the Centers for POCT for sexually transmitted disease, POCT for the future of Cancer Care, POCT primary care research network, gathered together for a modified deep dive workshop exploring the current state of the art, mapping probable future directions and developing longer term goals. The invitees were broken up into 4 thematic groups: Home, Outpatient, Public/shared space and Rural/global. Each group proceeded to explore the problem and solution space for point of care tests and technology within their theme. While each thematic area had specific challenges, many commonalities also emerged. This effort thus helped create a conceptual framework for POCT as well as identifying many of the challenges for POCT going forward. Four main dimensions were identified as defining the functional space for both point of care testing and treatment, these are: Time, Location, Interpretation and Tempo. A framework is presented in this paper. There were several current and future challenges identified through the workshop. These broadly fall into the categories of technology development and implementation. More specifically these are in the areas of: 1) Design, 2) Patient driven demand and technology, 3) Information Characteristics and Presentation, 4) Health Information Systems, 5) Connectivity, 6) Workflow and implementation, 7) Maintenance/Cost, and 8) Quality Control.

Practical considerations to guide development of access controls and decision support for genetic information in electronic medical records.

PubMed

Darcy, Diana C; Lewis, Eleanor T; Ormond, Kelly E; Clark, David J; Trafton, Jodie A

2011-11-02

Genetic testing is increasingly used as a tool throughout the health care system. In 2011 the number of clinically available genetic tests is approaching 2,000, and wide variation exists between these tests in their sensitivity, specificity, and clinical implications, as well as the potential for discrimination based on the results. As health care systems increasingly implement electronic medical record systems (EMRs) they must carefully consider how to use information from this wide spectrum of genetic tests, with whom to share information, and how to provide decision support for clinicians to properly interpret the information. Although some characteristics of genetic tests overlap with other medical test results, there are reasons to make genetic test results widely available to health care providers and counterbalancing reasons to restrict access to these test results to honor patient preferences, and avoid distracting or confusing clinicians with irrelevant but complex information. Electronic medical records can facilitate and provide reasonable restrictions on access to genetic test results and deliver education and decision support tools to guide appropriate interpretation and use. This paper will serve to review some of the key characteristics of genetic tests as they relate to design of access control and decision support of genetic test information in the EMR, emphasizing the clear need for health information technology (HIT) to be part of optimal implementation of genetic medicine, and the importance of understanding key characteristics of genetic tests when designing HIT applications.

The systems-based management of laboratory test ordering and results handling is a known source of error in primary care settings worldwide. The consequences are wide-ranging for patients (e.g. avoidable harm or poor care experience), general practitioners (e.g. delayed clinical decision making and potential medico-legal implications) and the primary care organization (e.g. increased allocation of resources to problem-solve and dealing with complaints). Guidance is required to assist care teams to minimize associated risks and improve patient safety. To identify, develop and build expert consensus on 'good practice' guidance statements to inform the implementation of safe systems for ordering laboratory tests and managing results in European primary care settings. Mixed methods studies were undertaken in the UK and Ireland, and the findings were triangulated to develop 'good practice' statements. Expert consensus was then sought on the findings at the wider European level via a Delphi group meeting during 2013. We based consensus on 10 safety domains and developed 77 related 'good practice' statements (≥ 80% agreement levels) judged to be essential to creating safety and minimizing risks in laboratory test ordering and subsequent results handling systems in international primary care. Guidance was developed for improving patient safety in this important area of primary care practice. We need to consider how this guidance can be made accessible to frontline care teams, utilized by clinical educators and improvement advisers, implemented by decision makers and evaluated to determine acceptability, feasibility and impacts on patient safety.

The demand for new healthcare services is growing rapidly. Improving accessibility of the African population to diabetes care seems to be a big challenge in most countries where the number of care centers and medical staff is reduced. Information and communication technologies (ICT) have great potential to address some of these challenges faced by several countries in providing accessible, cost-effective, and high-quality health care services. This paper presents the Mobil Diab system which is a telemedical approach proposed for the management of long-term diseases. The system applies modern mobile and web technologies which overcome geographical barriers, and increase access to health care services. The idea of the system is to involve patients in the therapy process and motivate them for an active participation. For validation of the system in African context, a trial was conducted in the Democratic Republic of Congo. 40 Subjects with diabetes divided randomly into control and intervention groups were included in the test. Results show that Mobil Diab is suitable for African countries and presents a number of benefits for the population and public health care system. It improves clinical management and delivery of diabetes care services by enhancing access, quality, motivation, reassurance, efficiency, and cost-effectiveness.

Implementation science: the laboratory as a command centre.

2017-03-01

Recent advances in point-of-care technologies to ensure universal access to affordable quality-assured diagnostics have the potential to transform patient management, surveillance programmes, and control of infectious diseases. Decentralization of testing can put tremendous stresses on fragile health systems if the laboratory is not involved in the planning, introduction, and scale-up strategies. The impact of investments in novel technologies can only be realized if these tests are evaluated, adopted, and scaled up within the healthcare system with appropriate planning and understanding of the local contexts in which these technologies will be used. In this digital age, the laboratory needs to take on the role of the Command Centre for technology introduction and implementation. Implementation science is needed to understand the political, cultural, economic, and behavioural context for technology introduction. The new paradigm should include: building a comprehensive system of laboratories and point-of-care testing sites to provide quality-assured diagnostic services with good laboratory-clinic interface to build trust in test results and linkage to care; building and coordinating a comprehensive national surveillance and communication system for disease control and global health emergencies; conducting research to monitor the impact of new tools and interventions on improving patient care.

Interpret perceptions of Colombian health professionals concerning factors that obstruct and facilitate the introduction of rapid syphilis and HIV testing in prenatal care services. A qualitative study based on semi-structured interviews was carried out. A convenience sample was selected with 37 participants, who included health professionals involved in prenatal care services, programs for pregnant women, clinical laboratories, and directors of health care units or centers, as well as representatives from regional departments and the Ministry of Health. Colombia does not do widespread screening with rapid syphilis and HIV tests in prenatal care. The professionals interviewed stated they did not have prior experience in the use of rapid tests-except for laboratory staff-or in the course of action in response to a positive result. The insurance system hinders access to timely diagnosis and treatment. Health authorities perceive a need to review existing standards, strengthen the first level of care, and promote comprehensive prenatal care starting with contracts between insurers and health service institutional providers. Participants recommended staff training and integration between health-policymaking and academic entities for updating training programs. The market approach and the characteristics of the Colombian health system constitute the main barriers to implementation of rapid testing as a strategy for elimination of mother-to-child transmission of syphilis and HIV. Measures identified include making changes in contracts between insurers and health service institutional providers, adapting the timing and duration of prenatal care procedures, and training physicians and nurses involved in prenatal care.

RFID offers great opportunities to health care. Nevertheless, prior experiences also show that RFID systems have not been designed and tested in response to the particular needs of health care settings and might introduce new risks. The aim of this study is to present a framework that can be used to assess the performance of RFID systems particularly in health care settings. We developed a framework describing a systematic approach that can be used for assessing the feasibility of using an RFID technology in a particular healthcare setting; more specific for testing the impact of environmental factors on the quality of RFID generated data and vice versa. This framework is based on our own experiences with an RFID pilot implementation in an academic hospital in The Netherlands and a literature review concerning RFID test methods and current insights of RFID implementations in healthcare. The implementation of an RFID system within the blood transfusion chain inside a hospital setting was used as a show case to explain the different phases of the framework. The framework consists of nine phases, including an implementation development plan, RFID and medical equipment interference tests, data accuracy- and data completeness tests to be run in laboratory, simulated field and real field settings. The potential risks that RFID technologies may bring to the healthcare setting should be thoroughly evaluated before they are introduced into a vital environment. The RFID performance assessment framework that we present can act as a reference model to start an RFID development, engineering, implementation and testing plan and more specific, to assess the potential risks of interference and to test the quality of the RFID generated data potentially influenced by physical objects in specific health care environments.

Anderson, Diana C; Jackson, Ashley A; Halpern, Neil A

Advanced informatics systems can help improve health care delivery and the environment of care for critically ill patients. However, identifying, testing, and deploying advanced informatics systems can be quite challenging. These processes often require involvement from a collaborative group of health care professionals of varied disciplines with knowledge of the complexities related to designing the modern and "smart" intensive care unit (ICU). In this article, we explore the connectivity environment within the ICU, middleware technologies to address a host of patient care initiatives, and the core informatics concepts necessary for both the design and implementation of advanced informatics systems.

To estimate the proportion of guideline nonadherent Pap tests in women aged younger than 21 years and older than 65 years and posthysterectomy in a single large health system. Secondary objectives were to describe temporal trends and patient and health care provider characteristics associated with screening in these groups. A retrospective cross-sectional chart review was performed at Fairview Health Services and University of Minnesota Physicians. Reasons for testing and patient and health care provider information were collected. Tests were designated as indicated or nonindicated per the 2012 cervical cancer screening guidelines. Point estimates and descriptive statistics were calculated. Patient and health care provider characteristics were compared between indicated and nonindicated groups using χ and Wilcoxon rank-sum tests. A total of 3,920 Pap tests were performed between September 9, 2012, and August 31, 2014. A total of 257 (51%; 95% confidence interval [CI] 46.1-54.9%) of tests in the younger than 21 years group, 536 (40%; 95% CI 37.7-43.1%) in the older than 65 years group, and 605 (29%; 95% CI 27.1-31.0%) in the posthysterectomy group were not indicated. White race in the older than 65 years group was the only patient characteristic associated with receipt of a nonindicated Pap test (P=.007). Health care provider characteristics associated with nonindicated Pap tests varied by screening group. Temporal trends showed a decrease in the proportion of nonindicated tests in the younger than 21 years group but an increase in the posthysterectomy group. For women aged younger than 21 years and older than 65 years and posthysterectomy, 35% of Pap tests performed in our health system were not guideline-adherent. There were no patient or health care provider characteristics associated with guideline nonadherent screening across all groups.

High-Value, Cost-Conscious Care: Iterative Systems-Based Interventions to Reduce Unnecessary Laboratory Testing.

Inappropriate testing contributes to soaring healthcare costs within the United States, and teaching hospitals are vulnerable to providing care largely for academic development. Via its "Choosing Wisely" campaign, the American Board of Internal Medicine recommends avoiding repetitive testing for stable inpatients. We designed systems-based interventions to reduce laboratory orders for patients admitted to the wards at an academic facility. We identified the computer-based order entry system as an appropriate target for sustainable intervention. The admission order set had allowed multiple routine tests to be ordered repetitively each day. Our iterative study included interventions on the automated order set and cost displays at order entry. The primary outcome was number of routine tests controlled for inpatient days compared with the preceding year. Secondary outcomes included cost savings, delays in care, and adverse events. Data were collected over a 2-month period following interventions in sequential years and compared with the year prior. The first intervention led to 0.97 fewer laboratory tests per inpatient day (19.4%). The second intervention led to sustained reduction, although by less of a margin than order set modifications alone (15.3%). When extrapolating the results utilizing fees from the Centers for Medicare and Medicaid Services, there was a cost savings of $290,000 over 2 years. Qualitative survey data did not suggest an increase in care delays or near-miss events. This series of interventions targeting unnecessary testing demonstrated a sustained reduction in the number of routine tests ordered, without adverse effects on clinical care.

New and affordable point-of-care testing (POCT) solutions are hoped to guide antibiotic prescription and to help limit antimicrobial resistance (AMR)-especially in low- and middle-income countries where resource constraints often prevent extensive diagnostic testing. Anthropological and sociological research has illuminated the role and impact of rapid point-of-care malaria testing. This paper expands our knowledge about the social implications of non-malarial POCT, using the case study of a C-reactive-protein point-of-care testing (CRP POCT) clinical trial with febrile patients at primary-care-level health centres in Chiang Rai province, northern Thailand. We investigate the social role of CRP POCT through its interactions with (a) the healthcare workers who use it, (b) the patients whose routine care is affected by the test, and (c) the existing patient-health system linkages that might resonate or interfere with CRP POCT. We conduct a thematic analysis of data from 58 purposively sampled pre- and post-intervention patients and healthcare workers in August 2016 and May 2017. We find widespread positive attitudes towards the test among patients and healthcare workers. Patients' views are influenced by an understanding of CRP POCT as a comprehensive blood test that provides specific diagnosis and that corresponds to notions of good care. Healthcare workers use the test to support their negotiations with patients but also to legitimise ethical decisions in an increasingly restrictive antibiotic policy environment. We hypothesise that CRP POCT could entail greater patient adherence to recommended antibiotic treatment, but it could also encourage riskier health behaviour and entail potentially adverse equity implications for patients across generations and socioeconomic strata. Our empirical findings inform the clinical literature on increasingly propagated point-of-care biomarker tests to guide antibiotic prescriptions, and we contribute to the anthropological and sociological literature through a novel conceptualisation of the patient-health system interface as an activity space into which biomarker testing is introduced.

To implement an electronic laboratory utilization management system (laboratory expert system [LES]) to provide safe and effective reductions in unnecessary clinical laboratory testing. The LES is a set of frequency filter subroutines within the Veterans Affairs hospital and laboratory information system that was formulated by an interdisciplinary medical team. Since implementing the LES, total test volume has decreased by a mean of 11.18% per year compared with our pre-LES test volume. This change was not attributable to fluctuations in outpatient visits or inpatient days of care. Laboratory cost savings were estimated at $151,184 and $163,751 for 2012 and 2013, respectively. A significant portion of these cost savings was attributable to reductions in high-volume, large panel testing. No adverse effects on patient care were reported, and mean length of stay for patients remained unchanged. Electronic laboratory utilization systems can effectively reduce unnecessary laboratory testing without compromising patient care.

Bruns, Eric J.; Hyde, Kelly L.; Sather, April; Hook, Alyssa; Lyon, Aaron R.

2015-01-01

Health information technology (HIT) and care coordination for individuals with complex needs are high priorities for quality improvement in health care. However, there is little empirical guidance about how best to design electronic health record systems and related technologies to facilitate implementation of care coordination models in behavioral health, or how best to apply user input to the design and testing process. In this paper, we describe an iterative development process that incorporated user/stakeholder perspectives at multiple points and resulted in an electronic behavioral health information system (EBHIS) specific to the wraparound care coordination model for youth with serious emotional and behavioral disorders. First, we review foundational HIT research on how EBHIS can enhance efficiency and outcomes of wraparound that was used to inform development. After describing the rationale for and functions of a prototype EBHIS for wraparound, we describe methods and results for a series of six small studies that informed system development across four phases of effort – predevelopment, development, initial user testing, and commercialization – and discuss how these results informed system design and refinement. Finally, we present next steps, challenges to dissemination, and guidance for others aiming to develop specialized behavioral health HIT. The research team's experiences reinforce the opportunity presented by EBHIS to improve care coordination for populations with complex needs, while also pointing to a litany of barriers and challenges to be overcome to implement such technologies.

Integration of HIV/AIDS services into African primary health care: lessons learned for health system strengthening in Mozambique - a case study

PubMed Central

2010-01-01

Introduction In 2004, Mozambique, supported by large increases in international disease-specific funding, initiated a national rapid scale-up of antiretroviral treatment (ART) and HIV care through a vertical "Day Hospital" approach. Though this model showed substantial increases in people receiving treatment, it diverted scarce resources away from the primary health care (PHC) system. In 2005, the Ministry of Health (MOH) began an effort to use HIV/AIDS treatment and care resources as a means to strengthen their PHC system. The MOH worked closely with a number of NGOs to integrate HIV programs more effectively into existing public-sector PHC services. Case Description In 2005, the Ministry of Health and Health Alliance International initiated an effort in two provinces to integrate ART into the existing primary health care system through health units distributed across 23 districts. Integration included: a) placing ART services in existing units; b) retraining existing workers; c) strengthening laboratories, testing, and referral linkages; e) expanding testing in TB wards; f) integrating HIV and antenatal services; and g) improving district-level management. Discussion: By 2008, treatment was available in nearly 67 health facilities in 23 districts. Nearly 30,000 adults were on ART. Over 80,000 enrolled in the HIV/AIDS program. Loss to follow-up from antenatal and TB testing to ART services has declined from 70% to less than 10% in many integrated sites. Average time from HIV testing to ART initiation is significantly faster and adherence to ART is better in smaller peripheral clinics than in vertical day hospitals. Integration has also improved other non-HIV aspects of primary health care. Conclusion The integration approach enables the public sector PHC system to test more patients for HIV, place more patients on ART more quickly and efficiently, reduce loss-to-follow-up, and achieve greater geographic HIV care coverage compared to the vertical model. Through the integration process, HIV resources have been used to rehabilitate PHC infrastructure (including laboratories and pharmacies), strengthen supervision, fill workforce gaps, and improve patient flow between services and facilities in ways that can benefit all programs. Using aid resources to integrate and better link HIV care with existing services can strengthen wider PHC systems. PMID:20180975

Nagykaldi, Zsolt; Mold, James W

2003-01-01

It has been demonstrated that electronic patient registries combined with a clinical decision support system have a significant positive impact on the documentation and delivery of services provided by health care professionals. While implementation of available commercial systems has not always been proven effective in a number of primary care practices, development and implementation of such a system in a practice-based research network might enhance successful implementation. Physicians in our practice-based research network (Oklahoma Physicians Resource/Research Network) initiated a project that aimed at designing, testing, and implementing a personal digital assistant-based diabetes management system. We utilized the "best practice" approach to determine the principles on which the application must operate. System development and beta testing were also accomplished based on the direct feedback of user clinicians. Practice Enhancement Assistants (PEAs) were available in the practices for assistance with implementation. Implementation of the Diabetes Patient Tracker (DPT) resulted in a significant improvement (p<0.05) in nine of 10 diabetic quality of care measures compared with pre-intervention levels in 20 primary care practices. Regular PEA visits similarly increased the number of foot exams and retinal exams performed in the last year (p=0.03 and 0.02, respectively). DPT is a low-cost, feasible, easily implementable, and very effective paper-less tool that significantly improves patient care and documentation in primary care practices.

Including safety-net providers in integrated delivery systems: issues and options for policymakers.

Witgert, Katherine; Hess, Catherine

2012-08-01

Health care reform legislation has spurred efforts to develop integrated health care delivery systems that seek to coordinate the continuum of health services. These systems may be of particular benefit to patients who face barriers to accessing care or have multiple health conditions. But it remains to be seen how safety-net providers, including community health centers and public hospitals--which have long experience in caring for these vulnerable populations--will be included in integrated delivery systems. This issue brief explores key considerations for incorporating safety-net providers into integrated delivery systems and discusses the roles of state and federal agencies in sup­porting and testing models of integrated care delivery. The authors conclude that the most important principles in creating integrated delivery systems for vulnerable populations are: (1) an emphasis on primary care; (2) coordination of all care, including behavioral, social, and public health services; and (3) accountability for population health outcomes.

Economic evaluations of point of care testing strategies for active tuberculosis.

PubMed

Zwerling, Alice; Dowdy, David

2013-06-01

Point of care (POC) diagnostics are often hailed as having the potential to transform tuberculosis (TB) control efforts. However, POC testing is better conceptualized as a system of diagnosis and treatment, not simply a test that can provide rapid, deployable results. Economic evaluations may help decision makers allocate scarce resources for TB control, but evaluations of POC testing face unique challenges that include evaluating the full diagnostic system, incorporating implementation costs, translating diagnostic results into health and accounting for downstream treatment costs. For economic evaluations to reach their full potential as decision-making tools for POC testing in TB, these challenges must be understood and addressed.

Health care delivery is increasingly influenced by the emerging concepts of precision health and the learning health care system. Although not synonymous with precision health, genomics is a key enabler of individualized care. Delivering patient-centered, genomics-informed care based on individual-level data in the current national landscape of health care delivery is a daunting challenge. Problems to overcome include data generation, analysis, storage, and transfer; knowledge management and representation for patients and providers at the point of care; process management; and outcomes definition, collection, and analysis. Development, testing, and implementation of a genomics-informed program requires multidisciplinary collaboration and building the concepts of precision health into a multilevel implementation framework. Using the principles of a learning health care system provides a promising solution. This article describes the implementation of population-based genomic medicine in an integrated learning health care system-a working example of a precision health program.

With the rising number of patients who rely on medical care, it is necessary to use evolving health care technology appropriately, to control health care costs, and to enhance the well-being of patients in the home care setting. Point of care testing (POCT)is instrumental system for such demands for home care; however, this term remains relatively unknown in Japan. For this research, I conducted a qualitative analysis of factors based on stories obtained through group interviews of 11 experienced home visiting nurses who work at three home-visit nursing stations for the purpose of clarifying issues in the introduction of POCT. The results of the research identified five categories and 16 subcategories for issues in the introduction of POCT. The identified categories are expected to be useful for the spread of POCT in the future. Key words: Point of care testing, Home care nursing.

Preventive quality measures for the foster care population are largely untested. The objective of the study is to identify healthcare quality measures for young children and adolescents in foster care and to test whether the data required to calculate these measures can be feasibly extracted and interpreted within an electronic health records or within the Statewide Automated Child Welfare Information System. The AAP Recommendations for Preventive Pediatric Health Care served as the guideline for determining quality measures. Quality measures related to well child visits, developmental screenings, immunizations, trauma-related care, BMI measurements, sexually transmitted infections and depression were defined. Retrospective chart reviews were performed on a cohort of children in foster care from a single large pediatric institution and related county. Data available in the Ohio Statewide Automated Child Welfare Information System was compared to the same population studied in the electronic health record review. Quality measures were calculated as observed (received) to expected (recommended) ratios (O/E ratios) to describe the actual quantity of recommended health care that was received by individual children. Electronic health records and the Statewide Automated Child Welfare Information System data frequently lacked important information on foster care youth essential for calculating the measures. Although electronic health records were rich in encounter specific clinical data, they often lacked custodial information such as the dates of entry into and exit from foster care. In contrast, Statewide Automated Child Welfare Information System included robust data on custodial arrangements, but lacked detailed medical information. Despite these limitations, several quality measures were devised that attempted to accommodate these limitations. In this feasibility testing, neither the electronic health records at a single institution nor the county level Statewide Automated Child Welfare Information System was able to independently serve as a reliable source of data for health care quality measures for foster care youth. However, the ability to leverage both sources by matching them at an individual level may provide the complement of data necessary to assess the quality of healthcare.

Background Patients with complex health care needs require the expertise of many health care providers. Communication, collaboration, and patient-centered care positively impact care quality and patient outcomes. Few technologies exist that facilitate collaboration between providers across settings of care and also engage the patient. We developed a Web-based clinical collaboration system, Loop, to address this gap. The likelihood of a technological system’s uptake is associated with its perceived ease of use and perceived usefulness. We engaged stakeholders in the conceptualization and development of Loop in an effort to maximize its intuitiveness and utility. Objective This study aimed to report end users’ perceptions about the ease of use and usefulness of Loop captured during usability tests of Loop. Methods Participants represented three user types (patients, caregivers, and health care providers) recruited from three populations (adults with cancer, adolescents and young adults with cancer, and children with medical complexity). We conducted usability testing over three iterative cycles of testing and development in both laboratory-based and off-site environments. We performed a content analysis of usability testing transcripts to summarize and describe participant perceptions about the ease of use and usefulness of Loop. Results Participants enjoyed testing Loop and were able to use the core functions—composing, posting, and reading messages—with little difficulty. They had difficulty interpreting certain visual cues and design elements or the purpose of some features. This difficulty negatively impacted perceived ease of use but was primarily limited to auxiliary features. Participants predicted that Loop could improve the efficiency and effectiveness of communication between care team members; however, this perceived usefulness could be compromised by disruptions to personal workflow such as additional time or task requirements. Conclusions Loop was perceived to have value as a collaboration system; however, usability testing findings indicate that some design and functional elements need to be addressed to improve ease of use. Additionally, participant concerns highlight the need to consider how a system can be implemented so as to minimize impact on workflow and optimize usefulness. PMID:29317386

Genetic Testing between Private and Public Interests: Some Legal and Ethical Reflections

PubMed Central

Sándor, Judit

2018-01-01

In Europe, there is a wide variety of genetic tests that various private companies offer to patients or to consumers. More and more people have become curious about their genetic predisposition and susceptibility. Most public health-care systems, however, are not adequately prepared for responding to these new demands and to the results of these genetic tests as, quite often, there is no available therapy for the identified genetic condition. This discrepancy between the newly emerging expectations and the insufficient responses contributes to a further rift between the public and private sectors of health care. Individual genetic test results may also trigger the need for personalized medicine and may open up a competition between the two fields in offering further genetic tests and medical exams. Pro-active patients may need a different kind of information on genetic tests and their implications. In this context, how should the public health system deal with the challenges of private testing? Will private genetic testing transform health care from a solidarity-based system to an individualistic one? In this paper, I would like to explore the emerging legal and ethical issues related to genetic testing and the relevant legal framework that has developed so far. In the conclusion, I will examine the possibilities of further legal development. PMID:29445722

2015-05-01

Health care infrastructure constitutes a major component of the structural quality of a health system. Infrastructural deficiencies of health services are reported in literature and research. A number of instruments exist for the assessment of infrastructure. However, no easy-to-use instruments to assess health facility infrastructure in developing countries are available. Present tools are not applicable for a rapid assessment by health facility staff. Therefore, health information systems lack data on facility infrastructure. A rapid assessment tool for the infrastructure of primary health care facilities was developed by the authors and pilot-tested in Tanzania. The tool measures the quality of all infrastructural components comprehensively and with high standardization. Ratings use a 2-1-0 scheme which is frequently used in Tanzanian health care services. Infrastructural indicators and indices are obtained from the assessment and serve for reporting and tracing of interventions. The tool was pilot-tested in Tanga Region (Tanzania). The pilot test covered seven primary care facilities in the range between dispensary and district hospital. The assessment encompassed the facilities as entities as well as 42 facility buildings and 80 pieces of technical medical equipment. A full assessment of facility infrastructure was undertaken by health care professionals while the rapid assessment was performed by facility staff. Serious infrastructural deficiencies were revealed. The rapid assessment tool proved a reliable instrument of routine data collection by health facility staff. The authors recommend integrating the rapid assessment tool in the health information systems of developing countries. Health authorities in a decentralized health system are thus enabled to detect infrastructural deficiencies and trace the effects of interventions. The tool can lay the data foundation for district facility infrastructure management.

As the symptoms and signs of heart diseases that cause sudden cardiac death, cardiac arrhythmia has attracted great attention. Due to limitations in time and space, traditional approaches to cardiac arrhythmias detection fail to provide a real-time continuous monitoring and testing service applicable in different environmental conditions. Integrated with the latest technologies in ECG (electrocardiograph) analysis and medical care, the pervasive computing technology makes possible the ubiquitous cardiac care services, and thus brings about new technical challenges, especially in the formation of cardiac care architecture and realization of the real-time automatic ECG detection algorithm dedicated to care devices. In this paper, a ubiquitous cardiac care prototype system is presented with its architecture framework well elaborated. This prototype system has been tested and evaluated in all the clinical-/home-/outdoor-care modes with a satisfactory performance in providing real-time continuous cardiac arrhythmias monitoring service unlimitedly adaptable in time and space.

Sustaining ongoing relationships with patients is a strategic, clinically relevant goal of health care systems. This study develops and tests a conceptual model that aims to account for the influence of organization design, perceptions of quality of patient care, and other patient-level factors on the extent to which patients sustain reliance on a health care system. We use a longitudinal survey design and structural equation modeling to predict increases or decreases in patient reliance on the Department of Veterans Affairs health care system across a 4-year period for Veterans with Parkinson's Disease. Our findings show that specialized and integrated clinical practices have a positive association with the quality of patient care. Health care systems may be able to foster long-term relations with patients and improve service quality by allocating resources to form integrated, specialized, disease-specific centers of care designed for patients with chronic illnesses. © The Author(s) 2016.

to determine if a combination of Minimum Data Set/Resident Assessment Instrument (MDS/RAI) assessment variables and the Resource Utilisation Groups version III (RUG-III) case-mix system could be used as a method of identifying and reimbursing registered nursing care needs in long-term care. the sample included 193 nursing home residents from four nursing homes from three different locations and care providers in England. The study included assessments of residents' care needs using either the MDS/RAI assessments or RUG stand-alone questionnaires and a time study that recorded the amount of nursing time received by residents over a 24-h period. Validity of RUG-III for explaining the distribution of care time between residents in different RUG-III groups was tested. The difference in direct and indirect care provided by registered general nurses (RGN) and care assistants (CA) to residents in RUG-III clinical groups was compared. the RUG-III system explained 56% of the variance in care time (Eta2, P=0.0001). Residents in RUG-III groups associated with particular medical and nursing needs (enhanced RGN care) received more than twice as much indirect RGN care time (t-test, P<0.001) and 1.4 times as much direct RGN and direct CA time (t-test, P<0.01) than residents with primarily cognitive impairment or physical problems only (standard RGN care). Residents with enhanced RGN care received an average of 48.1 min of RGN care in 24 h (95% CI 4.1-55.2) compared with an average of 31.1 min (95% CI 26.8-35.5) for residents in the standard RGN care group. A third low RGN care group was created following publication of the Department of Health guidance on NHS Funded Nursing Care. With three levels, the enhanced care group receives about 38% more than the standard group, and the low group receives about 50% of the standard group. the RUG-III system effectively differentiated between nursing home residents who are receiving 'low', 'standard' and 'enhanced' RGN care time. The findings could provide the basis of a reimbursement system for registered nursing time in long-term care facilities in the UK.

Background Clinical decision support systems (CDSS) have the potential to improve adherence to guidelines, but only if they are designed to work in the complex environment of ambulatory clinics as otherwise physicians may not use them. Objective To gain input from primary care physicians in designing a CDSS for smoking cessation to ensure that the design is appropriate to a clinical environment before attempts to test this CDSS in a clinical trial. This approach is of general interest to those designing similar systems. Design and Approach We employed an iterative ethnographic process that used multiple evaluation methods to understand physician preferences and workflow integration. Using results from our prior survey of physicians and clinic managers, we developed a prototype CDSS, validated content and design with an expert panel, and then subjected it to usability testing by physicians, followed by iterative design changes based on their feedback. We then performed clinical testing with individual patients, and conducted field tests of the CDSS in two primary care clinics during which four physicians used it for routine patient visits. Results The CDSS prototype was substantially modified through these cycles of usability and clinical testing, including removing a potentially fatal design flaw. During field tests in primary care clinics, physicians incorporated the final CDSS prototype into their workflow, and used it to assist in smoking cessation interventions up to eight times daily. Conclusions A multi-method evaluation process utilizing primary care physicians proved useful for developing a CDSS that was acceptable to physicians and patients, and feasible to use in their clinical environment.

This study summarizes the development and piloting of the Transitions from Foster Care Key Leader Survey (TFC-KLS), an instrument designed to measure change in systems serving young people transitioning from foster care to adulthood. The Jim Casey Youth Opportunity Initiative's logic model was used as a basis for instrument development. The instrument was piloted with 119 key leaders in six communities. Seven of eight latent scales performed well in psychometric testing. The relationships among the 24 measures of system change were explored. A CFA testing overall model fit was satisfactory following slight modifications. Finally, a test of inter-rater reliability between two raters did not find reliable reporting of service availability in a supplemental portion of the survey. The findings were generally positive and supported the validity and utility of the instrument for measuring system change, following some adaptations. Implications for the field are discussed.

Fecal occult blood testing (FOBT) is an important option for colorectal cancer screening that should be available in order to achieve high population screening coverage. However, results from a national survey of clinical practice in 1999-2000 indicated that many primary care physicians used inadequate methods to implement FOBT screening and follow-up. To determine whether methods to screen for fecal occult blood have improved, including the use of newer more sensitive stool tests. Cross-sectional national survey of primary care physicians. Participants consisted of 1,134 primary care physicians who reported ordering or performing FOBT in the 2006-2007 National Survey of Primary Care Physicians' Recommendations and Practices for Cancer Screening. Self-reported data on details of FOBT implementation and follow-up of positive results. Most physicians report using standard guaiac tests; higher sensitivity guaiac tests and immunochemical tests were reported by only 22.0% and 8.9%, respectively. In-office testing, that is, testing of a single specimen collected during a digital rectal examination in the office, is still widely used although inappropriate for screening: 24.9% of physicians report using only in-office tests and another 52.9% report using both in-office and home tests. Recommendations improved for follow-up after a positive test: fewer physicians recommend repeating the FOBT (17.8%) or using tests other than colonoscopy for the diagnostic work-up (6.6%). Only 44.3% of physicians who use home tests have reminder systems to ensure test completion and return. Many physicians continue to use inappropriate methods to screen for fecal occult blood. Intensified efforts to inform physicians of recommended technique and promote the use of tracking systems are needed.

Introduction: Significant event analysis (SEA) is well established in many primary care settings but can be poorly implemented. Reasons include the emotional impact on clinicians and limited knowledge of systems thinking in establishing why events happen and formulating improvements. To enhance SEA effectiveness, we developed and tested “guiding tools” based on human factors principles. Methods: Mixed-methods development of guiding tools (Personal Booklet—to help with emotional demands and apply a human factors analysis at the individual level; Desk Pad—to guide a team-based systems analysis; and a written Report Format) by a multiprofessional “expert” group and testing with Scottish primary care practitioners who submitted completed enhanced SEA reports. Evaluation data were collected through questionnaire, telephone interviews, and thematic analysis of SEA reports. Results: Overall, 149/240 care practitioners tested the guiding tools and submitted completed SEA reports (62.1%). Reported understanding of how to undertake SEA improved postintervention (P < .001), while most agreed that the Personal Booklet was practical (88/123, 71.5%) and relevant to dealing with related emotions (93/123, 75.6%). The Desk Pad tool helped focus the SEA on systems issues (85/123, 69.1%), while most found the Report Format clear (94/123, 76.4%) and would recommend it (88/123, 71.5%). Most SEA reports adopted a systems approach to analyses (125/149, 83.9%), care improvement (74/149, 49.7), or planned actions (42/149, 28.2%). Discussion: Applying human factors principles to SEA potentially enables care teams to gain a systems-based understanding of why things go wrong, which may help with related emotional demands and with more effective learning and improvement.

Mixed-methods development of guiding tools (Personal Booklet-to help with emotional demands and apply a human factors analysis at the individual level; Desk Pad-to guide a team-based systems analysis; and a written Report Format) by a multiprofessional "expert" group and testing with Scottish primary care practitioners who submitted completed enhanced SEA reports. Evaluation data were collected through questionnaire, telephone interviews, and thematic analysis of SEA reports. Overall, 149/240 care practitioners tested the guiding tools and submitted completed SEA reports (62.1%). Reported understanding of how to undertake SEA improved postintervention (P < .001), while most agreed that the Personal Booklet was practical (88/123, 71.5%) and relevant to dealing with related emotions (93/123, 75.6%). The Desk Pad tool helped focus the SEA on systems issues (85/123, 69.1%), while most found the Report Format clear (94/123, 76.4%) and would recommend it (88/123, 71.5%). Most SEA reports adopted a systems approach to analyses (125/149, 83.9%), care improvement (74/149, 49.7), or planned actions (42/149, 28.2%). Applying human factors principles to SEA potentially enables care teams to gain a systems-based understanding of why things go wrong, which may help with related emotional demands and with more effective learning and improvement.

Chocol, C. J.

1978-01-01

End-to-end tests of a 16 element indium antimonide sensor array and 10 channels of associated electronic signal processing were completed. Quantitative data were gathered on system responsivity, frequency response, noise, stray capacitance effects, and sensor paralleling. These tests verify that the temperature accuracies, predicted in the Task 1 study, can be obtained with a very carefully designed electro-optical flight system. Pre-flight and inflight calibration of a high quality are mandatory to obtain these accuracies. Also, optical crosstalk in the array-dewar assembly must be carefully eliminated by its design. Tests of the scaled up tracking system reticle also demonstrate that the predicted tracking system accuracies can be met in the flight system. In addition, improvements in the reticle pattern and electronics are possible, which will reduce the complexity of the flight system and increase tracking accuracy.

Analytical interferences in point-of-care testing glucometers by icodextrin and its metabolites: an overview.

PubMed

Floré, Katelijne M J; Delanghe, Joris R

2009-01-01

Current point-of-care testing (POCT) glucometers are based on various test principles. Two major method groups dominate the market: glucose oxidase-based systems and glucose dehydrogenase-based systems using pyrroloquinoline quinone (GDH-PQQ) as a cofactor. The GDH-PQQ-based glucometers are replacing the older glucose oxidase-based systems because of their lower sensitivity for oxygen. On the other hand, the GDH-PQQ test method results in falsely elevated blood glucose levels in peritoneal dialysis patients receiving solutions containing icodextrin (e.g., Extraneal; Baxter, Brussels, Belgium). Icodextrin is metabolized in the systemic circulation into different glucose polymers, but mainly maltose, which interferes with the GDH-PQQ-based method. Clinicians should be aware of this analytical interference. The POCT glucometers based on the GDH-PQQ method should preferably not be used in this high-risk population and POCT glucose results inconsistent with clinical suspicion of hypoglycemic coma should be retested with another testing system.

Point-of-care technologies (POC or POCT) are enabling innovative cardiovascular diagnostics that promise to improve patient care across diverse clinical settings. The National Heart, Lung, and Blood Institute convened a working group to discuss POCT in cardiovascular medicine. The multidisciplinary working group, which included clinicians, scientists, engineers, device manufacturers, regulatory officials, and program staff, reviewed the state of the POCT field; discussed opportunities for POCT to improve cardiovascular care, realize the promise of precision medicine, and advance the clinical research enterprise; and identified barriers facing translation and integration of POCT with existing clinical systems. A POCT development roadmap emerged to guide multidisciplinary teams of biomarker scientists, technologists, health care providers, and clinical trialists as they: 1) formulate needs assessments; 2) define device design specifications; 3) develop component technologies and integrated systems; 4) perform iterative pilot testing; and 5) conduct rigorous prospective clinical testing to ensure that POCT solutions have substantial effects on cardiovascular care.

Implementation of user-friendly, real-time, electronic medical records for patient management may lead to improved adherence to clinical guidelines and improved quality of patient care. We detail the systematic, iterative process that implementation partners, Lighthouse clinic and Baobab Health Trust, employed to develop and implement a point-of-care electronic medical records system in an integrated, public clinic in Malawi that serves HIV-infected and tuberculosis (TB) patients. Baobab Health Trust, the system developers, conducted a series of technical and clinical meetings with Lighthouse and Ministry of Health to determine specifications. Multiple pre-testing sessions assessed patient flow, question clarity, information sequencing, and verified compliance to national guidelines. Final components of the TB/HIV electronic medical records system include: patient demographics; anthropometric measurements; laboratory samples and results; HIV testing; WHO clinical staging; TB diagnosis; family planning; clinical review; and drug dispensing. Our experience suggests that an electronic medical records system can improve patient management, enhance integration of TB/HIV services, and improve provider decision-making. However, despite sufficient funding and motivation, several challenges delayed system launch including: expansion of system components to include of HIV testing and counseling services; changes in the national antiretroviral treatment guidelines that required system revision; and low confidence to use the system among new healthcare workers. To ensure a more robust and agile system that met all stakeholder and user needs, our electronic medical records launch was delayed more than a year. Open communication with stakeholders, careful consideration of ongoing provider input, and a well-functioning, backup, paper-based TB registry helped ensure successful implementation and sustainability of the system. Additional, on-site, technical support provided reassurance and swift problem-solving during the extended launch period. Even when system users are closely involved in the design and development of an electronic medical record system, it is critical to allow sufficient time for software development, solicitation of detailed feedback from both users and stakeholders, and iterative system revisions to successfully transition from paper to point-of-care electronic medical records. For those in low-resource settings, electronic medical records for integrated care is a possible and positive innovation.

Screening decreases colorectal cancer (CRC) morbidity and mortality, yet remains underutilized. Screening breakdowns arise from lack of uptake and failure to follow-up after a positive screening test. Systems of support to increase colorectal cancer screening and follow-up (SOS) is a randomized trial designed to increase: (1) CRC screening and (2) follow-up of positive screening tests. The Chronic Care Model and the Preventive Health Model inform study design. The setting is a large nonprofit healthcare organization. In part-1 study, patients age 50-75 due for CRC screening are randomized to one of 4 study conditions. Arm 1 receives usual care. Arm 2 receives automated support (mailed information about screening choices and fecal occult blood tests (FOBT)). Arm 3 receives automated and assisted support (a medical assistant telephone call). Arm 4 receives automated, assisted, and care management support (a registered nurse provides behavioral activation and coordination of care). In part-2, study patients with a positive FOBT or adenomas on flexible sigmoidoscopy are randomized to receive either usual care or nurse care management. Primary outcomes are: 1) the proportion with CRC screening, 2) the proportion with a complete diagnostic evaluation after a positive screening test. We sent recruitment letters to 15,414 patients and 4675 were randomized. Randomly assigned treatment groups were similar in age, sex, race, education, self-reported health, and CRC screening history. We will determine the effectiveness and cost effectiveness of stepped increases in systems of support to increase CRC screening and follow-up after a positive screening test over 2years.

ISO/TC 212 covering clinical laboratory testing and in vitro diagnostic test systems will issue the international standard for medical laboratory quality and competence requirements, ISO 15189. This standard is based on the ISO/IEC 17025, general requirements for competence of testing and calibration laboratories and ISO 9001, quality management systems-requirements. Clinical laboratory services are essential to patient care and therefore should be available to meet the needs of all patients and clinical personnel responsible for human health care. If a laboratory seeks accreditation, it should select an accreditation body that operates according to this international standard and in a manner which takes into account the particular requirements of clinical laboratories. Proficiency testing should be available to evaluate the calibration laboratories and reference measurement laboratories in clinical medicine. Reference measurement procedures should be of precise and the analytical principle of measurement applied should ensure reliability. We should be prepared to establish a quality management system and proficiency testing in clinical laboratories.

Those in practice find that the fee-for-service system does not adequately value the contributions made by primary care. The Center for Medicare and Medicaid Innovation (Innovation Center) was created by the Affordable Care Act to test new models of health care delivery to improve the quality of care while lowering costs. All programs coming out of the Innovation Center are tests of new payment and service delivery models. By changing both payment and delivery models and moving to a payment model that rewards physicians for quality of care instead of volume of care, we may be able to achieve the kind of health care patients want to receive and primary care physicians want to provide.

Twelve engineering type tests were performed on several subsystems and experiment(s) of the OAO 3 spacecraft near its end of mission. The systems tested include: Princeton experiment package (PEP), fine error system guidance, inertial reference unit, star trackers, heat pipes, thermal control coatings, command and data handling, solar array; batteries, and onboard processor/power boost regulator. Generally, the systems performed well for the 8 1/2 years life of OAO 3, although some degradation was noted in the sensitivity of PEP and in the absorptivity of the skin coatings. Battery life was prolonged during the life of the mission in large part by carefully monitoring the charge-discharge cycle with careful attention not to overcharge.

Discussing goals of care and advance care planning is beneficial, yet how to best integrate goals of care communication into clinical care remains unclear. To develop and determine the feasibility of a structured goals of care communication guide for nurses and social workers. Developmental study with providers in an academic and Veterans Affairs (VA) health system (n = 42) and subsequent pilot testing with patients with chronic obstructive pulmonary disease or heart failure (n = 15) and informal caregivers (n = 4) in a VA health system. During pilot testing, the communication guide was administered, followed by semistructured, open-ended questions about the content and process of communication. Changes to the guide were made iteratively, and subsequent piloting occurred until no additional changes emerged. Provider and patient feedback to the communication guide. Iterative input resulted in the goals of care communication guide. The guide included questions to elicit patient understanding of and attitudes toward the future of illness, clarify values and goals, identify end-of-life preferences, and agree on a follow-up plan. Revisions to guide content and phrasing continued during development and pilot testing. In pilot testing, patients validated the importance of the topic; none said the goals of care discussion should not be conducted. Patients and informal caregivers liked the final guide length (∼30 minutes), felt it flowed well, and was clear. In this developmental and pilot study, a structured goals of care communication guide was iteratively designed, implemented by nurses and social workers, and was feasible based on administration time and acceptability by patients and providers.

Forecasting client transitions in British Columbia's Long-Term Care Program.

Lane, D; Uyeno, D; Stark, A; Gutman, G; McCashin, B

1987-01-01

This article presents a model for the annual transitions of clients through various home and facility placements in a long-term care program. The model, an application of Markov chain analysis, is developed, tested, and applied to over 9,000 clients (N = 9,483) in British Columbia's Long Term Care Program (LTC) over the period 1978-1983. Results show that the model gives accurate forecasts of the progress of groups of clients from state to state in the long-term care system from time of admission until eventual death. Statistical methods are used to test the modeling hypothesis that clients' year-over-year transitions occur in constant proportions from state to state within the long-term care system. Tests are carried out by examining actual year-over-year transitions of each year's new admission cohort (1978-1983). Various subsets of the available data are analyzed and, after accounting for clear differences among annual cohorts, the most acceptable model of the actual client transition data occurred when clients were separated into male and female groups, i.e., the transition behavior of each group is describable by a different Markov model. To validate the model, we develop model estimates for the numbers of existing clients in each state of the long-term care system for the period (1981-1983) for which actual data are available. When these estimates are compared with the actual data, total weighted absolute deviations do not exceed 10 percent of actuals. Finally, we use the properties of the Markov chain probability transition matrix and simulation methods to develop three-year forecasts with prediction intervals for the distribution of the existing total clients into each state of the system. The tests, forecasts, and Markov model supplemental information are contained in a mechanized procedure suitable for a microcomputer. The procedure provides a powerful, efficient tool for decision makers planning facilities and services in response to the needs of long-term care clients. PMID:3121537

In the USA, 21% of the estimated 1.1 million people living with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) are unaware they are HIV-infected. In 2011, Veterans Health Administration (VHA)'s Office of Public Health in conjunction with VHA's Health Care for Homeless Veterans Program funded grants to support rapid HIV testing at homeless outreach events because homeless populations are more likely to obtain emergent rather than preventive care and have a higher HIV seroprevalence as compared to the general population. Because of a Veterans Affairs North Texas Health Care System (VANTHCS)'s laboratory testing requirement, VANTHCS partnered with community agencies to offer rapid HIV testing for the first time at VANTHCS' 2011 Homeless Stand Downs in Dallas, Fort Worth, and Texoma, Texas. Homeless Stand Downs are outreach events that connect Veterans with services. Veterans who declined testing were asked their reasons for declining. Comparisons by Homeless Stand Down site used Pearson χ², substituting Fisher's Exact tests for expected cell sizes <5. Of the 910 Veterans attending the Homeless Stand Downs, 261 Veterans reported reasons for declining HIV testing, and 133 Veterans were tested, where 92% of the tested Veterans obtained their test results at the events - all tested negative. Veterans' reported reasons for declining HIV testing included previous negative result (n=168), no time to test (n=49), no risk factors (n=36), testing is not a priority (n=11), uninterested in knowing serostatus (n=6), and HIV-infected (n=3). Only "no time to test" differed significantly by Homeless Stand Down site. Nonresponse rate was 54%. Offering rapid HIV testing at Homeless Stand Downs is a promising testing venue since 15% of Veterans attending VANTHCS' Homeless Stand Downs were tested for HIV, and majority obtained their HIV test results at point-of-care while further research is needed to determine how to improve these rates.

Management of uncontrolled symptoms is an important component of quality cancer care. Clinical guidelines are available for optimal symptom management, but are not often integrated into the front lines of care. The use of clinical decision support (CDS) at the point-of-care is an innovative way to incorporate guideline-based symptom management into routine cancer care. The objective of this study was to develop and evaluate a rule-based CDS system to enable management of multiple symptoms in lung cancer patients at the point-of-care. This study was conducted in three phases involving a formative evaluation, a system evaluation, and a contextual evaluation of clinical use. In Phase 1, we conducted iterative usability testing of user interface prototypes with patients and health care providers (HCPs) in two thoracic oncology clinics. In Phase 2, we programmed complex algorithms derived from clinical practice guidelines into a rules engine that used Web services to communicate with the end-user application. Unit testing of algorithms was conducted using a stack-traversal tree-spanning methodology to identify all possible permutations of pathways through each algorithm, to validate accuracy. In Phase 3, we evaluated clinical use of the system among patients and HCPs in the two clinics via observations, structured interviews, and questionnaires. In Phase 1, 13 patients and 5 HCPs engaged in two rounds of formative testing, and suggested improvements leading to revisions until overall usability scores met a priori benchmarks. In Phase 2, symptom management algorithms contained between 29 and 1425 decision nodes, resulting in 19 to 3194 unique pathways per algorithm. Unit testing required 240 person-hours, and integration testing required 40 person-hours. In Phase 3, both patients and HCPs found the system usable and acceptable, and offered suggestions for improvements. A rule-based CDS system for complex symptom management was systematically developed and tested. The complexity of the algorithms required extensive development and innovative testing. The Web service-based approach allowed remote access to CDS knowledge, and could enable scaling and sharing of this knowledge to accelerate availability, and reduce duplication of effort. Patients and HCPs found the system to be usable and useful. ©David F Lobach, Ellis B Johns, Barbara Halpenny, Toni-Ann Saunders, Jane Brzozowski, Guilherme Del Fiol, Donna L Berry, Ilana M Braun, Kathleen Finn, Joanne Wolfe, Janet L Abrahm, Mary E Cooley.

We evaluated the effect of a disease management (DM) program on adherence with recommended laboratory tests, health outcomes, and health care expenditures for patients with type 2 diabetes. The study was a natural experiment in a primary care setting in which the intervention was available to 1 group and then compared to the experience of a matched control group. Univariate analysis and difference in differences analysis were used to test for any significant differences between the 2 groups following a 12-month intervention period. A payer perspective was used to estimate the health care cost consequences based on hospital and physician utilization weighted by Medicare prices. The results were nonsignificant at the .10 level, except for compliance with recommended tests, which showed significant results in the univariate analysis. The intervention increased compliance with testing for HbA1c, microalbuminuria, and lipids, and decreased HbA1c value and the percent of patients with HbA1c >or=9.5%. The point estimates showed small reductions in health care cost; only reductions in costs for office visits were significant at the .10 level. We concluded that while there were signs of improvement in adherence to testing, the low effectiveness may be attributed to existing diabetes management activities in this primary care setting, high compliance rates for testing at the beginning of the study, and a steep learning curve for this complex, information-technology-based DM system. The study raises questions about the incremental gains from complex systems approaches to DM and illustrates a rigorous method to assess DM programs under "real-world" conditions, with control for possible selection bias.

One in seven of the 1.1 million people living in the United States infected with HIV are not aware of their HIV status. At the same time, many clinical settings have not adopted routine HIV screening, which promotes linkage to specialist medical care. We sought to improve HIV screening in a large community health center network by using a data-driven, collaborative learning approach and system-wide modifications, where counselor-based HIV screening and testing were replaced by health-care providers and medical assistants. Urban Health Plan, Inc., a network of federally qualified health centers in the boroughs of the Bronx and Queens in New York City, provided HIV screening training for its health-care providers. In January 2011, it modified its electronic medical record system to incorporate HIV test offering. This study compared the 2010 baseline year with the three-year implementation follow-up period (January 2011 through December 2013) to determine the number of eligible individuals for HIV testing, HIV tests offered and performed, HIV-positive individuals, and HIV cases linked to specialty care. A total of 26,853 individuals at baseline and 100,369 individuals in the implementation period were eligible for HIV testing. HIV testing was performed on 2,079 (8%) of 26,853 eligible individuals in 2010 and 49,646 (50%) of 100,369 eligible individuals from 2011 through 2013. HIV-positive status was determined in 19 (0.9%) of 2,079 tested individuals in 2010 and 166 (0.3%) of 49,646 tested individuals from 2011 through 2013. Linkage to care was observed in all 19 eligible individuals and 127 (77%) of 166 eligible individuals who tested HIV positive in 2010 and 2011-2013, respectively. This study enabled routine HIV implementation testing at a community health center network, which resulted in enhanced HIV testing, an increased number of HIV-positive cases identified, and a rise in the number of patients linked to HIV specialist care.

Disorders of the coagulation system can seriously impact the clinical course and outcome of neurosurgical patients. Due to the anatomical location of the central nervous system within the closed skull, bleeding complications can lead to devastating consequences such as an increase in intracranial pressure or enlargement of intracranial hematoma. Point-of-care (POC) devices for the testing of haemostatic parameters have been implemented in various fields of medicine. Major advantages of these devices are that results are available quickly and that analysis can be performed at the bedside, directly affecting patient management. POC devices allow identification of increased bleeding tendencies and therefore may enable an assessment of hemorrhagic risks in neurosurgical patients. Although data regarding the use of POC testing in neurosurgical patients are limited, they suggest that coagulation testing and hemostatic therapy using POC devices might have beneficial effects in this patient population. This article provides an overview of the application of point-of-care coagulation testing in clinical practice in neurosurgical patients. Georg Thieme Verlag KG Stuttgart · New York.

Centralized testing demands costly laboratories, which are inefficient and may provide poor services. Recent advances make it feasible to move clinical testing nearer to patients and the requesting physicians, thus reducing the time to treatment. Internet technologies can be used to create a virtual laboratory information system in a distributed health-care environment. This allows clinical testing to be transferred to a cooperative scheme of several point-of-care testing (POCT) nodes. Two pilot virtual laboratories were established, one in Italy (AUSL Modena) and one in Greece (Athens Medical Centre). They were constructed on a three-layer model to allow both technical and clinical verification. Different POCT devices were connected. The pilot sites produced good preliminary results in relation to user acceptance, efficiency, convenience and costs. Decentralized laboratories can be expected to become cost-effective.

To improve the oral health of low-income children, innovations in dental delivery systems are needed, including community-based care, the use of expanded duty auxiliary dental personnel, capitation payments, and global budgets. This paper describes the protocol for PREDICT (Population-centered Risk- and Evidence-based Dental Interprofessional Care Team), an evaluation project to test the effectiveness of new delivery and payment systems for improving dental care and oral health. This is a parallel-group cluster randomized controlled trial. Fourteen rural Oregon counties with a publicly insured (Medicaid) population of 82,000 children (0 to 21 years old) and pregnant women served by a managed dental care organization are randomized into test and control counties. In the test intervention (PREDICT), allied dental personnel provide screening and preventive services in community settings and case managers serve as patient navigators to arrange referrals of children who need dentist services. The delivery system intervention is paired with a compensation system for high performance (pay-for-performance) with efficient performance monitoring. PREDICT focuses on the following: 1) identifying eligible children and gaining caregiver consent for services in community settings (for example, schools); 2) providing risk-based preventive and caries stabilization services efficiently at these settings; 3) providing curative care in dental clinics; and 4) incentivizing local delivery teams to meet performance benchmarks. In the control intervention, care is delivered in dental offices without performance incentives. The primary outcome is the prevalence of untreated dental caries. Other outcomes are related to process, structure and cost. Data are collected through patient and staff surveys, clinical examinations, and the review of health and administrative records. If effective, PREDICT is expected to substantially reduce disparities in dental care and oral health. PREDICT can be disseminated to other care organizations as publicly insured clients are increasingly served by large practice organizations. ClinicalTrials.gov NCT02312921 6 December 2014.

2014-01-01

Background Although clinical applications such as emergency medicine and prehospital care could benefit from a fast-mounting electroencephalography (EEG) recording system, the lack of specifically designed equipment restricts the use of EEG in these environments. Methods This paper describes the design and testing of a six-channel emergency EEG (emEEG) system with a rapid preparation time intended for use in emergency medicine and prehospital care. The novel system comprises a quick-application cap, a device for recording and transmitting the EEG wirelessly to a computer, and custom software for displaying and streaming the data in real-time to a hospital. Bench testing was conducted, as well as healthy volunteer and patient measurements in three different environments: a hospital EEG laboratory, an intensive care unit, and an ambulance. The EEG data was evaluated by two experienced clinical neurophysiologists and compared with recordings from a commercial system. Results The bench tests demonstrated that the emEEG system's performance is comparable to that of a commercial system while the healthy volunteer and patient measurements confirmed that the system can be applied quickly and that it records quality EEG data in a variety of environments. Furthermore, the recorded data was judged to be of diagnostic quality by two experienced clinical neurophysiologists. Conclusions In the future, the emEEG system may be used to record high-quality EEG data in emergency medicine and during ambulance transportation. Its use could lead to a faster diagnostic, a more accurate treatment, and a shorter recovery time for patients with neurological brain disorders. PMID:24886096

To investigate educational disparities in the care process and health outcomes among patients with diabetes in the context of South Korea's universal health insurance system. Bivariate and multiple regression analyses of data from a cross-sectional health survey. A nationally representative and population-based survey, the 2005 Korea National Health and Nutrition Examination Survey. Respondents aged 40 or older who self-reported prior diagnosis with diabetes (n= 1418). Seven measures of the care process and health outcomes, namely (i) receiving medical treatment for diabetes, (ii) ever received diabetes education, (iii) received dilated eye examination in the past year, (iv) received microalbuminuria test in the past year, (v) having activity limitation due to diabetes, (vi) poor self-rated health and (vii) self-rated health on a visual analog scale. Except for receiving medical care for diabetes, overall process quality was low, with only 25% having ever received diabetes education, 39% having received a dilated eye examination in the past year and 51% having received a microalbuminuria test in the past year. Lower education level was associated with both poorer care processes and poorer health outcomes, whereas lower income level was only associated with poorer health outcomes. While South Korea's universal health insurance system may have succeeded in substantially reducing financial barriers related to diabetes care, the quality of diabetes care is low overall and varies by education level. System-level quality improvement efforts are required to address the weaknesses of the health system, thereby mitigating educational disparities in diabetes care quality.

Managing test results is an important issue in hospitals because of the increasing use of point-of-care testing (POCT). Here, we propose a smartphone-based system for automatically managing POCT test results. We developed the system to provide convenience to the medical staffs. The system recognizes the patient identification or prescription number of the test by reading barcodes and provides a countdown to indicate when the results will be ready. When the countdown in finished, a picture of the test result is transferred to the electronic medical record server using the Health Level 7 protocol. Human immunodeficiency virus (HIV) kits were selected in this research because HIV is a life-threatening infectious virus, especially for the medical staff who treat undiagnosed patients. The performance of the system was verified from a survey of the users. The performance of the system was tested at the emergency room (ER) for 10 months using commercially available POCT kits for detecting HIV. The survey showed that, in total, 80% and 0% of users reported positive or negative feedback, respectively. The staff also reported that the system reduced total processing time by approximately 32 min, in addition to reducing workload. The developed automated management system was successfully tested at an ER for 10 months. The survey results show that the system is effective and that medical staff members who used the system are satisfied with using the system at the ER.

To obtain indications of the influence of electronic health records (EHR) in managing risks and meeting information system accreditation standard in Australian residential aged care (RAC) homes. The hypothesis to be tested is that the RAC homes using EHR have better performance in meeting information system standards in aged care accreditation than their counterparts only using paper records for information management. Content analysis of aged care accreditation reports from the Aged Care Standards and Accreditation Agency produced between April 2011 and December 2013. Items identified included types of information systems, compliance with accreditation standards, and indicators of failure to meet an expected outcome for information systems. The Chi-square test was used to identify difference between the RAC homes that used EHR systems and those that used paper records in not meeting aged care accreditation standards. 1,031 (37.4%) of 2,754 RAC homes had adopted EHR systems. Although the proportion of homes that met all accreditation standards was significantly higher for those with EHR than for homes with paper records, only 13 RAC homes did not meet one or more expected outcomes. 12 used paper records and nine of these failed the expected outcome for information systems. The overall contribution of EHR to meeting aged care accreditation standard in Australia was very small. Risk indicators for not meeting information system standard were no access to accurate and appropriate information, failure in monitoring mechanisms, not reporting clinical incidents, insufficient recording of residents' clinical changes, not providing accurate care plans, and communication processes failure. The study has provided indications that use of EHR provides small, yet significant advantages for RAC homes in Australia in managing risks for information management and in meeting accreditation requirements. The implication of the study for introducing technology innovation in RAC in Australia is discussed.

Patient satisfaction is the ultimate goal of healthcare system which can be achieved from good patient-healthcare professional relationship and quality of healthcare services provided. Study was conducted to determine the baseline satisfaction level of newly diagnosed diabetics and to explore the impact of pharmaceutical care intervention on patients' satisfaction during their follow-ups in a tertiary care teaching hospital in Nepal. An interventional, pre-post non-clinical randomised controlled study was designed among randomly distributed 162 [control group (n = 54), test 1 group (n = 54) and test 2 group (n = 54)] newly diagnosed diabetes mellitus patients by consecutive sampling method for 18 months. Diabetes Patient Satisfaction Questionnaire was used to evaluate patient's satisfaction scores at baseline, three, six, nine and, twelve months' follow-ups. Test groups patients were provided pharmaceutical care whereas control group patients only received their usual care from physician/nurses. The responses were entered in SPSS version 16. Data distribution was not normal on Kolmogorov-Smirnov test. Non-parametric tests i.e. Friedman test, Mann-Whitney U test and Wilcoxon signed rank test were used to find the differences among the groups before and after the intervention (p ≤0.05). There were significant (p < 0.001) improvements in patients' satisfaction scores in the test groups on Friedman test. Mann-Whitney U test identified the significant differences in satisfaction scores between test 1 and test 2 groups, control and test 1 groups and, control and test 2 groups at 3-months (p = 0.008), (p < 0.001) and (p < 0.001), 6-months (p = 0.010), (p < 0.001) and (p < 0.001), 9-months (p < 0.001), (p < 0.001) and (p < 0.001) and, 12-months (p < 0.001), (p < 0.001) and (p < 0.001) follow-ups respectively. Pharmaceutical care intervention significantly improved the satisfaction level of diabetics in the test groups compare to the control group. Diabetic kit demonstration strengthened the satisfaction level among the test 2 group patients. Therefore, pharmacist can act as a counsellor through pharmaceutical care program and assist the patients in managing their disease. This will not only modify the patients' related outcomes and their level of satisfaction but also improve the healthcare system.

Adoption of evidence-based practices takes place at a glacial place in healthcare. This research will pilot test an innovative implementation strategy - systems consultation -intended to speed the adoption of evidence-based practice in primary care. The strategy is based on tenets of systems engineering and has been extensively tested in addiction treatment. Three innovations have been included in the strategy - translation of a clinical practice guideline into a checklist-based implementation guide, the use of physician peer coaches ('systems consultants') to help clinics implement the guide, and a focus on reducing variation in practices across prescribers and clinics. The implementation strategy will be applied to improving opioid prescribing practices in primary care, which may help ultimately mitigate the increasing prevalence of opioid abuse and addiction. The pilot test will compare four intervention clinics to four control clinics in a matched-pairs design. A leading clinical guideline for opioid prescribing has been translated into a checklist-based implementation guide in a systematic process that involved experts who wrote the guideline in consultation with implementation experts and primary care physicians. Two physicians with expertise in family and addiction medicine are serving as the systems consultants. Each systems consultant will guide two intervention clinics, using two site visits and follow-up communication by phone and email, to implement the translated guideline. Mixed methods will be used to test the feasibility, acceptability, and preliminary effectiveness of the implementation strategy in an evaluation that meets standards for 'fully developed use' of the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance). The clinic will be the primary unit of analysis. The systems consultation implementation strategy is intended to generalize to the adoption of other clinical guidelines. This pilot test is intended to prepare for a large randomized clinical trial that will test the strategy against other implementation strategies, such as audit/feedback and academic detailing, used to close the gap between knowledge and practice. The systems consultation approach has the potential to shorten the famously long time it takes to implement evidence-based practices and clinical guidelines in healthcare.

2000-02-01

Failure to slow the exponential growth of total health care expenditures in the United States through the government policies resulted in a rapid and progressive penetration of managed care organizations(MCOs) in the early 1990s. Diagnostic testing is viewed as a "commodity" rather than a medical service under the managed care environment. Traditional hospital-based laboratories are placed in a downward spiral with the advent of managed care era. A massive reduction of in-house testing resulted from shorter lengths of patients' hospital stay and a marked decrease in admission under the dominance of managed care urges them to develop strategies for restoring tests deprived by the managed care-associated new businesses: consolidation and networking, participation in the outreach-testing market, and point-of-care/satellite laboratory testing in non-traditional, ambulatory settings are major strategies for survival of hospital laboratories. A number of physicians' office laboratories(POLs) have been closed owing to regulatory restrictions imposed by the Clinical Laboratory Improvement Amendments of 1988(CLIA '88), and to the expanded penetration of MCOs which limit reimbursement to a very few in-house procedures. It seems likely that POLs and hospital laboratories continue to reduce test volumes, while commercial reference laboratories(CRLs) gain more tests through contracting with MCOs. In the current stream of managed care dominance in the United States, clinical laboratories are changing their basic operation focus and mission in response to the aggressively changing landscape. Traditional laboratories which are unwilling to adapt themselves to the new environment will not survive in this country.

Utilisation, contents and costs of prenatal care under a rural health insurance (New Co-operative Medical System) in rural China: lessons from implementation

PubMed Central

2010-01-01

Background In China, the New Co-operative Medical System (NCMS), a rural health insurance system, has expanded nationwide since 2003. This study aims to describe prenatal care use, content and costs of care in one county where prenatal care is included in the NCMS and two counties where it is not. It also explores the perceptions of stakeholders of the prenatal care benefit package in order to understand the strengths and weaknesses of the approach in the context of rural China and to draw lessons from early implementation. Methods This study is based on the data from a cross-sectional survey and a qualitative investigation conducted in 2009. A survey recruited women giving birth in 2008, including 544 women in RC County (which covered prenatal care) and 619, and 1071 in other two counties (which did not). The qualitative investigation in RC included focus group discussions with women giving birth before or after 2007, individual interviews with local policy makers and health managers, NCMS managers and obstetric doctors in township hospitals. Results There were no significant differences in prenatal care use between RC County (which covered prenatal care) and other two counties (which did not): over 70% of women started prenatal visits early and over 60% had five or more visits. In the three counties: a small proportion of women received the number of haemoglobin and urine tests recommended by the national guideline; 90% of women received more ultrasound tests than recommended; and the out-of-pocket expenditure for prenatal care consumed a high proportion of women's annual income in the low income group. In RC: only 20% of NCMS members claimed the reimbursement; the qualitative study found that the reimbursement for prenatal care was not well understood by women and had little influence on women's decisions to make prenatal visits; and several women indicated that doctors suggested them taking more expensive tests. Conclusions Whether or not prenatal care was included in the NCMS, prenatal care use was high, but the contents of care were not provided following the national guideline and more expensive tests were recommended by doctors. Costs were substantial for the poor. PMID:21040560

To test how the implementation of new Medicare post-acute payment systems affected the use of inpatient rehabilitation facilities (IRFs), skilled nursing facilities (SNFs), and home health agencies. Medicare acute hospital, IRF, and SNF claims; provider of services file; enrollment file; and Area Resource File data. We used multinomial logit models to measure realized access to post-acute care and to predict how access to alternative sites of care changed in response to prospective payment systems. A file was constructed linking data for elderly Medicare patients discharged from acute care facilities between 1996 and 2003 with a diagnosis of hip fracture, stroke, or lower extremity joint replacement. Although the effects of the payment systems on the use of post-acute care varied, most reduced the use of the site of care they directly affected and boosted the use of alternative sites of care. Payment system changes do not appear to have differentially affected the severely ill. Payment system incentives play a significant role in determining where Medicare beneficiaries receive their post-acute care. Changing these incentives results in shifting of patients between post-acute sites.

Development and reliability of an observation method to assess food intake of young children in child care.

To our knowledge, a direct observation protocol for assessing dietary intake among young children in child care has not been published. This article reviews the development and testing of a diet observation system for child care facilities that occurred during a larger intervention trial. Development of this system was divided into five phases, done in conjunction with a larger intervention study; (a) protocol development, (b) training of field staff, (c) certification of field staff in a laboratory setting, (d) implementation in a child-care setting, and (e) certification of field staff in a child-care setting. During the certification phases, methods were used to assess the accuracy and reliability of all observers at estimating types and amounts of food and beverages commonly served in child care. Tests of agreement show strong agreement among five observers, as well as strong accuracy between the observers and 20 measured portions of foods and beverages with a mean intraclass correlation coefficient value of 0.99. This structured observation system shows promise as a valid and reliable approach for assessing dietary intake of children in child care and makes a valuable contribution to the growing body of literature on the dietary assessment of young children.

Reaching hepatitis C virus elimination targets requires health system interventions to enhance the care cascade.

Modelling suggests that achieving the World Health Organization's elimination targets for hepatitis C virus (HCV) is possible by scaling up use of direct-acting antiviral (DAA) therapy. However, poor linkage to health services and retention in care presents a major barrier, in particular among people who inject drugs (PWID). We identify and assess the cost-effectiveness of additional health system interventions required to achieve HCV elimination targets in Australia, a setting where all people living with HCV have access to DAA therapy. We used a dynamic HCV transmission and liver-disease progression mathematical model among current and former PWID, capturing testing, treatment and other features of the care cascade. Interventions tested were: availability of point-of-care RNA testing; increased testing of PWID; using biomarkers in place of liver stiffness measurement; and scaling up primary care treatment delivery. The projected treatment uptake in Australia reduced the number of people living with HCV from approximately 230,000 in 2015 to approximately 24,000 by 2030 and reduced incidence by 45%. However, the majority (74%) of remaining infections were undiagnosed and among PWID. Scaling up primary care treatment delivery and using biomarkers in place of liver stiffness measurement only reduced incidence by a further 1% but saved AU$32 million by 2030, with no change to health outcomes. Additionally replacing HCV antibody testing with point-of-care RNA testing increased healthcare cost savings to AU$62 million, increased incidence reduction to 64% and gained 11,000 quality-adjusted life years, but critically, additional screening of PWID was required to achieve HCV elimination targets. Even with unlimited and unrestricted access to HCV DAA treatment, interventions to improve the HCV cascade of care and target PWID will be required to achieve elimination targets.

2016-06-01

Healthcare systems are working to move towards more integrated, patient-centered care. This study describes the development and testing of a multidimensional self-report measure of patients' experiences of integrated care. Random-digit-dial telephone survey in 2012 of 317 adults aged 40 years or older in the San Francisco region who had used healthcare at least twice in the past 12 months. One-time cross-sectional survey; psychometric evaluation to confirm dimensions and create multi-item scales. Survey data were analyzed using VARCLUS and confirmatory factor analysis and internal consistency reliability testing. Scales measuring five domains were confirmed: coordination within and between care teams, navigation (arranging appointments and visits), communication between specialist and primary care doctor, and communication between primary care doctor and specialist. Four of these demonstrated excellent internal consistency reliability. Mean scale scores indicated low levels of integration. These scales measuring integrated care capture meaningful domains of patients' experiences of health care. The low levels of care integration reported by patients in the study sample suggest that these types of measures should be considered in ongoing evaluations of health system performance and improvement. Further research should examine whether differences in patient experience of integrated care are associated with differences in the processes and outcomes of care received.

Collaborative Chronic Care Networks (C3Ns) to transform chronic illness care.

Margolis, Peter A; Peterson, Laura E; Seid, Michael

2013-06-01

Despite significant gains by pediatric collaborative improvement networks, the overall US system of chronic illness care does not work well. A new paradigm is needed: a Collaborative Chronic Care Network (C3N). A C3N is a network-based production system that harnesses the collective intelligence of patients, clinicians, and researchers and distributes the production of knowledge, information, and know-how over large groups of people, dramatically accelerating the discovery process. A C3N is a platform of "operating systems" on which interconnected processes and interventions are designed, tested, and implemented. The social operating system is facilitated by community building, engaging all stakeholders and their expertise, and providing multiple ways to participate. Standard progress measures and a robust information technology infrastructure enable the technical operating system to reduce unwanted variation and adopt advances more rapidly. A structured approach to innovation design provides a scientific operating system or "laboratory" for what works and how to make it work. Data support testing and research on multiple levels: comparative effectiveness research for populations, evaluating care delivery processes at the care center level, and N-of-1 trials and other methods to select the best treatment of individual patient circumstances. Methods to reduce transactional costs to participate include a Federated IRB Model in which centers rely on a protocol approved at 1 central institutional review board and a "commons framework" for organizational copyright and intellectual property concerns. A fully realized C3N represents a discontinuous leap to a self-developing learning health system capable of producing a qualitatively different approach to improving health.

Background. Despite the availability of rapid diagnostic tests and inexpensive treatment for pregnant women, maternal-child syphilis transmission remains a leading cause of perinatal morbidity and mortality in developing countries. In Haiti, more than 3000 babies are born with congenital syphilis annually. Methods and Findings. From 2007 to 2011, we used a sequential time series, multi-intervention study design in fourteen clinics throughout Haiti to improve syphilis testing and treatment in pregnancy. The two primary interventions were the introduction of a rapid point-of-care syphilis test and systems strengthening based on quality improvement (QI) methods. Syphilis testing increased from 91.5% prediagnostic test to 95.9% after (P < 0.001) and further increased to 96.8% (P < 0.001) after the QI intervention. Despite high rates of testing across all time periods, syphilis treatment lagged behind and only increased from 70.3% to 74.7% after the introduction of rapid tests (P = 0.27), but it improved significantly from 70.2% to 84.3% (P < 0.001) after the systems strengthening QI intervention. Conclusion. Both point-of-care diagnostic testing and health systems-based quality improvement interventions can improve the delivery of specific evidence-based healthcare interventions to prevent congenital syphilis at scale in Haiti. Improved treatment rates for syphilis were seen only after the use of systems-based quality improvement approaches. PMID:26316955

This article describes the design, development, and testing of the Health Care Safety Hotline, a prototype consumer reporting system for patient safety events. The prototype was designed and developed with ongoing review by a technical expert panel and feedback obtained during a public comment period. Two health care delivery organizations in one metropolitan area collaborated with the researchers to demonstrate and evaluate the system. The prototype was deployed and elicited information from patients, family members, and caregivers through a website or an 800 phone number. The reports were considered useful and had little overlap with information received by the health care organizations through their usual risk management, customer service, and patient safety monitoring systems. However, the frequency of reporting was lower than anticipated, suggesting that further refinements, including efforts to raise awareness by actively soliciting reports from subjects, might be necessary to substantially increase the volume of useful reports. It is possible that a single technology platform could be built to meet a variety of different patient safety objectives, but it may not be possible to achieve several objectives simultaneously through a single consumer reporting system while also establishing trust with patients, caregivers, and providers.

Ensuring the safe, effective management of patients requires efficient processes of care within a smoothly operating system in which highly reliable teams of talented, skilled health care providers are able to use the vast array of high-technology resources and intensive care techniques available. Simulation can play a unique role in exploring and improving the complex perioperative system by proactively identifying latent safety threats and mitigating their damage to ensure that all those who work in this critical health care environment can provide optimal levels of patient care. A panel of five experts from a wide range of institutions was brought together to discuss the added value of simulation-based training for improving systems-based aspects of the perioperative service line. Panelists shared the way in which simulation was demonstrated at their institutions. The themes discussed by each panel member were delineated into four avenues through which simulation-based techniques have been used. Simulation-based techniques are being used in (1) testing new clinical workspaces and facilities before they open to identify potential latent conditions; (2) practicing how to identify the deteriorating patient and escalate care in an effective manner; (3) performing prospective root cause analyses to address system weaknesses leading to sentinel events; and (4) evaluating the efficiency and effectiveness of the electronic health record in the perioperative setting. This focused review of simulation-based interventions to test and improve components of the perioperative microsystem, which includes literature that has emerged since the panel's presentation, highlights the broad-based utility of simulation-based technologies in health care.

The implications in personalized and precision cancer nursing care include interpretation and clinical use of novel and personalized information including genetic testing; patient advocacy and support throughout testing, anticipation of results and treatment; ongoing chronic monitoring; and support for patient decision-making. Attention must also be given to the family and ethical implications of a personalized approach to care. Nurses face increasing challenges and opportunities in communication, support, and advocacy for patients given the availability of advanced testing, care and treatment in personalized and precision medicine. Nursing education and continuing education, clinical decision support, and health systems changes will be necessary to provide personalized multidisciplinary care to patients, in which nurses play a key role.

Point-of-care tests for chlamydia (CT) and gonorrhoea (NG) could increase the uptake and timeliness of testing and treatment, contribute to improved disease control and reduce reproductive morbidity. The GeneXpert (Xpert CT/NG assay), suited to use at the point-of-care, is being used in the TTANGO randomised controlled trial (RCT) in 12 remote Australian health services with a high burden of sexually transmissible infections (STIs). This represents the first ever routine use of a molecular point-of-care diagnostic for STIs in primary care. The purpose of this study was to explore the acceptability of the GeneXpert to primary care staff in remote Australia. In-depth qualitative interviews were conducted with 16 staff (registered or enrolled nurses and Aboriginal Health Workers/Practitioners) trained and experienced with GeneXpert testing. Interviews were digitally-recorded and transcribed verbatim prior to content analysis. Most participants displayed positive attitudes, indicating the test was both easy to use and useful in their clinical context. Participants indicated that point-of-care testing had improved management of STIs, resulting in more timely and targeted treatment, earlier commencement of partner notification, and reduced follow up efforts associated with client recall. Staff expressed confidence in point-of-care test results and treating patients on this basis, and reported greater job satisfaction. While point-of-care testing did not negatively impact on client flow, several found the manual documentation processes time consuming, suggesting that improved electronic connectivity and test result transfer between the GeneXpert and patient management systems could overcome this. Managing positive test results in a shorter time frame was challenging for some but most found it satisfying to complete episodes of care more quickly.

Background Point-of-care tests for chlamydia (CT) and gonorrhoea (NG) could increase the uptake and timeliness of testing and treatment, contribute to improved disease control and reduce reproductive morbidity. The GeneXpert (Xpert CT/NG assay), suited to use at the point-of-care, is being used in the TTANGO randomised controlled trial (RCT) in 12 remote Australian health services with a high burden of sexually transmissible infections (STIs). This represents the first ever routine use of a molecular point-of-care diagnostic for STIs in primary care. The purpose of this study was to explore the acceptability of the GeneXpert to primary care staff in remote Australia. Methods In-depth qualitative interviews were conducted with 16 staff (registered or enrolled nurses and Aboriginal Health Workers/Practitioners) trained and experienced with GeneXpert testing. Interviews were digitally-recorded and transcribed verbatim prior to content analysis. Results Most participants displayed positive attitudes, indicating the test was both easy to use and useful in their clinical context. Participants indicated that point-of-care testing had improved management of STIs, resulting in more timely and targeted treatment, earlier commencement of partner notification, and reduced follow up efforts associated with client recall. Staff expressed confidence in point-of-care test results and treating patients on this basis, and reported greater job satisfaction. While point-of-care testing did not negatively impact on client flow, several found the manual documentation processes time consuming, suggesting that improved electronic connectivity and test result transfer between the GeneXpert and patient management systems could overcome this. Managing positive test results in a shorter time frame was challenging for some but most found it satisfying to complete episodes of care more quickly. Conclusions In the context of a RCT, health professionals working in remote primary care in Australia found the GeneXpert highly acceptable. These findings have implications for use in other primary care settings around the world. PMID:26713441

To understand how the results of laboratory tests are communicated to patients in primary care and perceptions on how the process may be improved. Qualitative study employing staff focus groups. Four UK primary care practices. Staff involved in the communication of test results. Five main themes emerged from the data: (i) the default method for communicating results differed between practices; (ii) clinical impact of results and patient characteristics such as anxiety level or health literacy influenced methods by which patients received their test result; (iii) which staff member had responsibility for the task was frequently unclear; (iv) barriers to communicating results existed, including there being no system or failsafe in place to determine whether results were returned to a practice or patient; (v) staff envisaged problems with a variety of test result communication methods discussed, including use of modern technologies, such as SMS messaging or online access. Communication of test results is a complex yet core primary care activity necessitating flexibility by both patients and staff. Dealing with the results from increasing numbers of tests is resource intensive and pressure on practice staff can be eased by greater utilization of electronic communication. Current systems appear vulnerable with no routine method of tracing delayed or missing results. Instead, practices only become aware of missing results following queries from patients. The creation of a test communication protocol for dissemination among patients and staff would help ensure both groups are aware of their roles and responsibilities. © The Author 2014.

Lynch syndrome is a hereditary cancer with confirmed carriers at high risk for colorectal (CRC) and extracolonic cancers. The purpose of the current study was to develop a greater understanding of the factors influencing decisions about disease management post-genetic testing. The study used a grounded theory approach to data collection and analysis as part of a multiphase project examining the psychosocial and behavioral impact of predictive DNA testing for Lynch syndrome. Individual and small group interviews were conducted with individuals from 10 families with the MSH2 intron 5 splice site mutation or exon 8 deletion. The data from confirmed carriers (n = 23) were subjected to re-analysis to identify key barriers to and/or facilitators of screening and disease management. Thematic analysis identified personal, health care provider and health care system factors as dominant barriers to and/or facilitators of managing Lynch syndrome. Person-centered factors reflect risk perceptions and decision-making, and enduring screening/disease management. The perceived knowledge and clinical management skills of health care providers also influenced participation in recommended protocols. The health care system barriers/facilitators are defined in terms of continuity of care and coordination of services among providers. Individuals with Lynch syndrome often encounter multiple barriers to and facilitators of disease management that go beyond the individual to the provider and health care system levels. The current organization and implementation of health care services are inadequate. A coordinated system of local services capable of providing integrated, efficient health care and follow-up, populated by providers with knowledge of hereditary cancer, is necessary to maintain optimal health.

Integrating care for people with complex needs is challenging. Indeed, evidence of solutions is mixed, and therefore, well-designed, shared evaluation approaches are needed to create cumulative learning. The Toronto-based Building Bridges to Integrate Care (BRIDGES) collaborative provided resources to refine and test nine new models linking primary, hospital and community care. It used mixed methods, a cross-project meta-evaluation and shared outcome measures. Given the range of skills required to develop effective interventions, a novel incubator was used to test and spread opportunities for system integration that included operational expertise and support for evaluation and process improvement.

This paper is an analysis of the social interaction between drug sellers, their clients and local health care workers within a medical trial that introduced rapid diagnostic tests for malaria into private sector drug shops in Mukono District, Uganda. It locates the introduction of a new technology to test blood and a system of referral within the context of local concerns about the choice and evaluation of treatment; and the socially legitimated statuses, roles and hierarchies within the local health care system. Based on the multi-layered interpretation of 21 focus group discussions, we describe three key aspects of the trial central to local interpretation: openly testing blood, supervisory visits to drug shops and a new referral form. Each had the potential to shift drug shop vendors from outsider to insider of the formal health service. The responses of the different groups of participants reflect their situation within the health care system. The clients and patients welcomed the local availability of new diagnostic technology and the apparent involvement of the government in securing good quality health services for them from providers with often uncertain credentials. The drug shop vendors welcomed the authorization to openly test blood, enabling the demonstration of a new skill and newfound legitimacy as a health worker rather than simple drug seller. Formal sector health workers were less enthusiastic about the trial, raising concerns about professional hierarchies and the maintenance of a boundary around the formal health service to ensure the exclusion of those they considered untrained, unprofessional and untrustworthy personnel.

“Reducing unnecessary testing in a CPOE system through implementation of a targeted CDS intervention”

PubMed Central

2013-01-01

Background We describe and evaluate the development and use of a Clinical Decision Support (CDS) intervention; an alert, in response to an identified medical error of overuse of a diagnostic laboratory test in a Computerized Physician Order Entry (CPOE) system. CPOE with embedded CDS has been shown to improve quality of care and reduce medical errors. CPOE can also improve resource utilization through more appropriate use of laboratory tests and diagnostic studies. Observational studies are necessary in order to understand how these technologies can be successfully employed by healthcare providers. Methods The error was identified by the Test Utilization Committee (TUC) in September, 2008 when they noticed critical care patients were being tested daily, and sometimes twice daily, for B-Type Natriuretic Peptide (BNP). Repeat and/or serial BNP testing is inappropriate for guiding the management of heart failure and may be clinically misleading. The CDS intervention consists of an expert rule that searches the system for a BNP lab value on the patient. If there is a value and the value is within the current hospital stay, an advisory is displayed to the ordering clinician. In order to isolate the impact of this intervention on unnecessary BNP testing we applied multiple regression analysis to the sample of 41,306 patient admissions with at least one BNP test at LVHN between January, 2008 and September, 2011. Results Our regression results suggest the CDS intervention reduced BNP orders by 21% relative to the mean. The financial impact of the rule was also significant. Multiplying by the direct supply cost of $28.04 per test, the intervention saved approximately $92,000 per year. Conclusions The use of alerts has great positive potential to improve care, but should be used judiciously and in the appropriate environment. While these savings may not be generalizable to other interventions, the experience at LVHN suggests that appropriately designed and carefully implemented CDS interventions can have a substantial impact on the efficiency of care provision.

2016-01-01

Early infant diagnosis (EID) and prompt linkage to care are critical to minimise the high morbidity and mortality associated with infant HIV infection. Attrition in the "EID cascade" is common; however, point-of-care (POC) EID assays with same-day result could facilitate prompt linkage of HIV-infected infant to treatment. Despite a number of POC EID assays in development, few have been independently evaluated and data on new technologies are urgently needed to inform policy. We compared Alere q 1/2 Detect POC system laboratory test characteristics with the local standard of care (SOC), Roche CAP/CTM HIV-1 qualitative PCR in an independent laboratory-based evaluation in Cape Town, South Africa. Routinely EID samples collected between November 2013 and September 2014 were each tested by both SOC and POC systems. Repeat testing was done to troubleshoot any discrepancy between POC and SOC results. Overall, 1098 children with a median age of 47 days (IQR, 42-117) were included. Birth PCR (age <7 days) comprised of 8% (n = 92) tests while 56% (n = 620) of children tested as part of routine EID (ages 6-14 weeks). In the overall direct comparison, Alere q Detect achieved sensitivity of 95.5% (95% CI, 91.7-97.9%) and a specificity of 99.8% (95% CI, 99.1-100%). Following repeat testing of discordant samples and exclusion of any inconclusive results, the POC assay sensitivity and specificity were 96.9% (95% CI 93.4-98.9%) and 100% (lower 95% CI 98%) respectively. Among birth PCR tests the POC assay had slightly lower sensitivity (93.3% vs 96.5% in routine EID) and higher assay error rate (10% vs 5% in samples of older children, p = 0.04). Our results indicate this POC assay performs well for EID in the laboratory. The high specificity and thus high positive predictive value would suggest a positive POC result may be adequate for immediate infant ART initiation. While POC testing for EID may have particular utility for birth testing at delivery facilities, the lower sensitivity and error rate requires further attention, as does field implementation of POC EID technologies in other clinical care settings.

Many of the target molecules that reside in blood are also present in oral fluids, albeit at lower concentrations. Oral fluids are, however, relatively easy and safe to collect without the need for specialized equipment and training. Thus, oral fluids provide convenient samples for medical diagnostics. Recent advances in lab-on-a-chip technologies have made minute, fully integrated diagnostic systems practical for an assortment of point-of-care tests. Such systems can perform either immunoassays or molecular diagnostics outside centralized laboratories within time periods ranging from minutes to an hour. The article briefly reviews recent advances in devices for point-of-care testing with a focus on work that has been carried out by the authors as part of a NIH program. PMID:21521419

Background Successful point-of-care testing, namely ensuring the completion of the test and treat cycle in the same encounter, has immense potential to reduce diagnostic and treatment delays, and impact patient outcomes. However, having rapid tests is not enough, as many barriers may prevent their successful implementation in point-of-care testing programs. Qualitative research on diagnostic practices may help identify such barriers across different points of care in health systems. Methods In this exploratory qualitative study, we conducted 78 semi-structured interviews and 13 focus group discussions in an urban and rural area of Karnataka, India, with healthcare providers (doctors, nurses, specialists, traditional healers, and informal providers), patients, community health workers, test manufacturers, laboratory technicians, program managers and policy-makers. Participants were purposively sampled to represent settings of hospitals, peripheral labs, clinics, communities and homes, in both the public and private sectors. Results In the Indian context, the onus is on the patient to ensure successful point-of-care testing across homes, clinics, labs and hospitals, amidst uncoordinated providers with divergent and often competing practices, in settings lacking material, money and human resources. We identified three overarching themes affecting point-of-care testing: the main theme is ‘relationships’ among providers and between providers and patients, influenced by the cross-cutting theme of ‘infrastructure’. Challenges with both result in ‘modified practices’ often favouring empirical (symptomatic) treatment over treatment guided by testing. Conclusions Even if tests can be conducted on the spot and infrastructure challenges have been resolved, relationships among providers and between patients and providers are crucial for successful point-of-care testing. Furthermore, these barriers do not act in isolation, but are interlinked and need to be examined as such. Also, a test alone has only limited power to overcome those difficulties. Test developers, policy-makers, healthcare providers and funders need to use these insights in overcoming barriers to point-of-care testing programs. PMID:26275231

Managing abnormal test results in primary care involves coordination across various settings. This study identifies how primary care teams manage test results in a large, computerized healthcare system in order to inform health information technology requirements for test results management and other distributed healthcare services. At five US Veterans Health Administration facilities, we interviewed 37 primary care team members, including 16 primary care providers, 12 registered nurses, and 9 licensed practical nurses. We performed content analysis using a distributed cognition approach, identifying patterns of information transmission across people and artifacts (e.g. electronic health records). Results illustrate challenges (e.g. information overload) as well as strategies used to overcome challenges. Various communication paths were used. Some team members served as intermediaries, processing information before relaying it. Artifacts were used as memory aids. Health information technology should address the risks of distributed work by supporting awareness of team and task status for reliable management of results.

This study tests functionality and acceptability of a new mHealth system in providing antenatal care amongst migrants. The study, carried out between 2014 and 2016, involved 150 pregnant women residing in the largest European migrant reception center in Sicily. A ticket tracking system assessed the system's functionality and a questionnaire assessed women's acceptability. The system facilitated the collection of clinical data, enabling the creation of electronic patient records and identifying 10% of pregnancies as high-risk. The application's digital format increased health providers' adherence to antenatal-care recommendations, while the graphic interface facilitated women's engagement and retention of the health education modules. The study recorded a 91.9% patient satisfaction rate. The system was efficient in providing comprehensive and high-quality antenatal care amongst migrants, facilitating the continuity of care for a population undergoing frequent relocations.

Managing respiratory care services.

Managing in a health care environment is not for the frail of heart or weak of spirit. Health care is a system in crisis that is exacerbated because it got there by doing what once made it successful. From 1900 to 2004, focus of health care has shifted from controlling infectious diseases to episodic care and to present-day chronic and perspective care. The system has moved from issues of mortality, to morbidity, to mobility, to quality of life, to feeling good and, finally, to looking good. Managing the delivery of health care, if you choose to accept it, is not an impossible mission, but it will be a challenging job. Obviously, the focus of managers is how the system can be designed to innovate and improve care. Organizations and professions must change not only structures and processes, but national priorities for improvement with better methods of disseminating and applying knowledge. Managers of respiratory care departments must foster the use of information technology in clinical care, must create payment policies that encourage innovation and tested performance, and must enhance education programs to strengthen and retain the health care work forces.

The National Library of Medicine (NLM) and the Agency for Health Care Policy and Research (AHCPR) are sponsoring a test to determine the extent to which a combination of existing health-related terminologies covers vocabulary needed in health information systems. The test vocabularies are the 30 that are fully or partially represented in the 1996 edition of the Unified Medical Language System (UMLS) Metathesaurus, plus three planned additions: the portions of SNOMED International not in the 1996 Metathesaurus Read Clinical Classification, and the Logical Observations Identifiers, Names, and Codes (LOINC) system. These vocabularies are available to testers through a special interface to the Internet-based UMLS Knowledge Source Server. The test will determine the ability of the test vocabularies to serve as a source of controlled vocabulary for health data systems and applications. It should provide the basis for realistic resource estimates for developing and maintaining a comprehensive "standard" health vocabulary that is based on existing terminologies. PMID:8816351

Variation of Care Time Between Nursing Units in Classification-Based Nurse-to-Resident Ratios: A Multilevel Analysis

2018-01-01

A validity test was conducted to determine how care level–based nurse-to-resident ratios compare with actual daily care times per resident in Germany. Stability across different long-term care facilities was tested. Care level–based nurse-to-resident ratios were compared with the standard minimum nurse-to-resident ratios. Levels of care are determined by classification authorities in long-term care insurance programs and are used to distribute resources. Care levels are a powerful tool for classifying authorities in long-term care insurance. We used observer-based measurement of assignable direct and indirect care time in 68 nursing units for 2028 residents across 2 working days. Organizational data were collected at the end of the quarter in which the observation was made. Data were collected from January to March, 2012. We used a null multilevel model with random intercepts and multilevel models with fixed and random slopes to analyze data at both the organization and resident levels. A total of 14% of the variance in total care time per day was explained by membership in nursing units. The impact of care levels on care time differed significantly between nursing units. Forty percent of residents at the lowest care level received less than the standard minimum registered nursing time per day. For facilities that have been significantly disadvantaged in the current staffing system, a higher minimum standard will function more effectively than a complex classification system without scientific controls.

Objective To test how the implementation of new Medicare post-acute payment systems affected the use of inpatient rehabilitation facilities (IRFs), skilled nursing facilities (SNFs), and home health agencies. Data Sources Medicare acute hospital, IRF, and SNF claims; provider of services file; enrollment file; and Area Resource File data. Study Design We used multinomial logit models to measure realized access to post-acute care and to predict how access to alternative sites of care changed in response to prospective payment systems. Data Extraction Methods A file was constructed linking data for elderly Medicare patients discharged from acute care facilities between 1996 and 2003 with a diagnosis of hip fracture, stroke, or lower extremity joint replacement. Principal Findings Although the effects of the payment systems on the use of post-acute care varied, most reduced the use of the site of care they directly affected and boosted the use of alternative sites of care. Payment system changes do not appear to have differentially affected the severely ill. Conclusions Payment system incentives play a significant role in determining where Medicare beneficiaries receive their post-acute care. Changing these incentives results in shifting of patients between post-acute sites. PMID:19490159

To develop and evaluate a Web-based, electronic pelvic floor symptoms assessment questionnaire (e-PAQ)1 for women. A cross-sectional study in primary and secondary care. Two general practices, two community health clinics and a secondary care urogynaecology clinic. A total of 432 women (204 in primary care and 228 in secondary care) were recruited between June 2003 and January 2004. The e-PAQ was located on a workstation (computer, touchscreen and printer). Women completed the e-PAQ prior to their appointment. Untreated women in primary care were asked to return seven days later to complete the e-PAQ a second time (test-retest). Factor analysis, reliability, validity, patient satisfaction, completion times and system costs. In secondary care, factor analysis identified 14 domains within the four dimensions (urinary, bowel, vaginal and sexual symptoms) with internal consistency (Cronbach's alpha)>or=0.7 in 11 of these. In primary care, alpha values were all>or=0.7 and test-retest analysis found acceptable intraclass correlations of 0.50-0.95 (P<0.001) for all domains. A measure of face validity and utility was gained using a nine-item questionnaire, which yielded strongly positive patient views on relevance and acceptability. The e-PAQ offers a user-friendly clinical tool, which provides valid and reliable data. The system offers comprehensive symptoms and quality of life evaluation and may enhance the clinical episode as well as the quality of care for women with pelvic floor disorders.

An alternative perspective on how laboratory medicine can contribute to solve the health care crisis: a model to save costs by acquiring excellence in diagnostic systems.

PubMed

Mussap, Michele

2014-01-01

The rapid escalation in health care costs has led to the idea to deliver better care at lower costs, reshaping the responsibilities of the health care system to achieve the goal of creating value for the patient. The pressure for fiscal containment and the progressive reduction in available health care resources originated very short term strategies consisting of abrupt reductions in expenditure, specifically in the provision of clinical pathology laboratory medicine services. However, the impact of laboratory test results on diagnostic and therapeutic interventions has increased enormously in the past decade, due to advances in personalized medicine and to the strictly correlated requirement to use new biomarkers with increasing sensitivity and specificity in clinical practice. In order to create savings by delivering better care there is the need to invest financial resources in purchasing high technology and new sophisticated tests and to promote the expertise of clinical pathologists and laboratory medicine professionals. This approach to creating value in patient health care is more productive and sustainable ethically, morally and economically as a long-term strategy. It can be successfully achieved by applying defined rules that make public-private cooperation clearer, skipping incompatible solutions such as transforming clinical laboratories to 'industrially productive premises', outsourcing laboratory medicine services and using central acquisition of diagnostic systems. © 2013.

Systems perspective: understanding care giving of the elderly in India.

2009-12-01

In this article I propose a systems model of elder care giver burden among Indian care givers. The systems model specifies the effects of elder characteristics, family structure, and personal characteristics of the care giver on care giver burden. Sampling was conducted using a multistage probability method to generate a sample of 259 care givers. The care giver burden questionnaire was translated from English to Hindi and then back into English and pilot tested before implementation. The care givers were interviewed via face-to-face interviews. Regression analysis was used to estimate the effects of the hypothesized determinants on care giver burden. The r square explained 46% of the variance in care giver burden. The following variables were significant from three dimensions: personal characteristics, elder characteristics, and family level. Personal characteristics of the care giver included whether they adhered to Asian cultural norms, the age of the care giver, and gender. Elder characteristics included behavioral problems of the elder. Family functional variables included number of care giving tasks provided by the care giver, and level of family income. Social work practice issues are discussed in the context of this study.

Patient-reported outcome (PRO) measures have been used widely to screen for depression, anxiety, and symptoms in cancer patients. Computer-based applications that collect patients' responses and transfer them to the treating health professional in real time have the potential to improve patient well-being and cancer outcomes. This study will test the feasibility and acceptability of a newly developed eHealth system which facilitates PRO data capture from cancer patients, data linkage and retrieval to support clinical decisions and patient self-management, and data retrieval to support ongoing evaluation and innovative research. The eHealth system is being developed in consultation with 3 overarching content-specific expert advisory groups convened for this project: the clinical advisory group, technical advisory group, and evaluation advisory group. The following work has already been completed during this phase of the study: the Patient-Reported Outcome Measures for Personalized Treatment and Care (PROMPT-Care) eHealth system was developed, patient-reported outcomes were selected (distress, symptoms, unmet needs), algorithms to inform intervention thresholds for clinical and self-management were determined, clinician PRO feedback summary and longitudinal reports were designed, and patient self-management resources were collated. PROsaiq, a custom information technology system, will transfer PRO data in real time into the hospital-based oncology information system to support clinical decision making. The PROMPT-Care system feasibility and acceptability will be assessed through patients completing PROMPT-Care assessments, participating in face-to-face cognitive interviews, and completing evaluation surveys and telephone interviews and oncology staff participating in telephone interviews. Over the course of 3 months, the system will be pilot-tested with up to 50 patients receiving treatment or follow-up care and 6 oncology staff at 2 hospitals in New South Wales, Australia. Data will be collected to determine the accuracy and completeness of data transfer procedures, extent of missing data from participants' assessments, acceptability of the eHealth system and usefulness of the self-management resources (via patient evaluation surveys and interviews), and acceptability and perceived usefulness of real-time PRO reporting (via oncology staff interviews) at the completion of the pilot phase. This research investigates implementation of evidence into real world clinical practice through development of an efficient and user-friendly eHealth system. This study of feasibility and acceptability of the newly developed eHealth system will inform the next stage of larger scale testing and future implementation of the system as part of routine care.

Goal ambiguity influences the effectiveness of performance management systems to drive organizations toward enhanced results. The literature analyzes the antecedents of goal ambiguity and shows the influence of goal ambiguity on the performance of U.S. federal agencies. However, no study has analyzed goal ambiguity in other countries or in health care systems. This study has three aims: to test the validity of a measurement instrument for goal ambiguity, to investigate its main antecedents, and to explore the relationship between goal ambiguity and organizational performance in a large, public, Beveridge-type health care system. A nationwide survey of general managers of the Italian national health system was performed. A factor analysis was used to validate the mono-dimensionality of an instrument that measured goal ambiguity. Structural equation modeling was used to test both the antecedents and the influence of goal ambiguity on organizational performance. Data from 135 health care organizations (53% response rate) were available for analysis. The results confirm the mono-dimensionality of the instrument, the existence of two environmental sources of ambiguity (political endorsement and governance commitment), and the negative relationship between goal ambiguity and organizational performance. Goal ambiguity matters because it may hamper organizational performance. Therefore, performance should be fostered by reducing goal ambiguity (e.g., goal-setting model, funding arrangements, and political support). Mutatis mutandis, our results may apply to public health care systems of other countries or other "public interest" sectors, such as social care and education.

Since the publication of the first "Hospital Hygiene Guideline for the implementation and operation of air conditioning systems (HVAC systems) in hospitals" (http://www.krankenhaushygiene.de/informationen/fachinformationen/leitlinien/12) in 2002, it was necessary due to the increase in knowledge, new regulations, improved air-conditioning systems and advanced test methods to revise the guideline. Based on the description of the basic features of ventilation concepts, its hygienic test and the usage-based requirements for ventilation, the DGKH section "Ventilation and air conditioning technology" attempts to provide answers for the major air quality issues in the planning, design and the hygienically safe operation of HVAC systems in rooms of health care.

Background: The need to improve coordination of care at end of life has driven electronic palliative care coordination systems implementation across the United Kingdom and internationally. No approaches for evaluating electronic palliative care coordination systems use in practice have been developed. Aim: This study outlines and applies an evaluation framework for examining how and when electronic documentation of advance care planning is occurring in end of life care services. Design: A pragmatic, formative process evaluation approach was adopted. The evaluation drew on the Project Review and Objective Evaluation methodology to guide the evaluation framework design, focusing on clinical processes. Setting/participants: Data were extracted from electronic palliative care coordination systems for 82 of 108 general practices across a large UK city. All deaths (n = 1229) recorded on electronic palliative care coordination systems between April 2014 and March 2015 were included to determine the proportion of all deaths recorded, median number of days prior to death that key information was recorded and observations about routine data use. Results: The evaluation identified 26.8% of all deaths recorded on electronic palliative care coordination systems. The median number of days to death was calculated for initiation of an electronic palliative care coordination systems record (31 days), recording a patient’s preferred place of death (8 days) and entry of Do Not Attempt Cardiopulmonary Resuscitation decisions (34 days). Where preferred and actual place of death was documented, these were matching for 75% of patients. Anomalies were identified in coding used during data entry on electronic palliative care coordination systems. Conclusion: This study reports the first methodology for evaluating how and when electronic palliative care coordination systems documentation is occurring. It raises questions about what can be drawn from routine data collected through electronic palliative care coordination systems and outlines considerations for future evaluation. Future evaluations should consider work processes of health professionals using electronic palliative care coordination systems. PMID:27507636

Automated evaluation of electronic discharge notes to assess quality of care for cardiovascular diseases using Medical Language Extraction and Encoding System (MedLEE)

PubMed Central

Lin, Jou-Wei; Yang, Chen-Wei

2010-01-01

The objective of this study was to develop and validate an automated acquisition system to assess quality of care (QC) measures for cardiovascular diseases. This system combining searching and retrieval algorithms was designed to extract QC measures from electronic discharge notes and to estimate the attainment rates to the current standards of care. It was developed on the patients with ST-segment elevation myocardial infarction and tested on the patients with unstable angina/non-ST-segment elevation myocardial infarction, both diseases sharing almost the same QC measures. The system was able to reach a reasonable agreement (κ value) with medical experts from 0.65 (early reperfusion rate) to 0.97 (β-blockers and lipid-lowering agents before discharge) for different QC measures in the test set, and then applied to evaluate QC in the patients who underwent coronary artery bypass grafting surgery. The result has validated a new tool to reliably extract QC measures for cardiovascular diseases. PMID:20442141

Evaluation of Hematocrit Influence on Self-Monitoring of Blood Glucose Based on ISO 15197:2013: Comparison of a Novel System With Five Systems With Different Hematocrit Ranges.

2018-03-01

ISO 15197:2013 recommends testing procedures and acceptance criteria for the evaluation of influence quantities such as hematocrit on measurement results with systems for self-monitoring of blood glucose (SMBG). In this study, hematocrit influence was evaluated for a novel SMBG system (system A) and five other systems with different hematocrit ranges based on ISO 15197:2013. Test procedures were performed with one test strip lot for each system. Each system was tested within the hematocrit range indicated in the manufacturer's labeling (system A: 10-65%, B: 15-65%, C: 20-60%, D: 35-60%, E: 30-60%, F: 30-55%). According to ISO 15197:2013, clause 6.4.2, venous blood samples were used for the evaluation of hematocrit influence. The evaluation was performed for three glucose concentration categories (30-50 mg/dL, 96-144 mg/dL, and 280-420 mg/dL). For each glucose concentration category, at least five different hematocrit levels were investigated. The novel system A and systems B, E, and F complied with the tested lot with the defined criteria and showed ≤10 mg/dL and ≤10% difference between the test sample and the respective control sample with a hematocrit value of 42% ± 2% for BG concentrations <100 mg/dL and ≥100 mg/dL, respectively. Two systems showed >10% difference at glucose concentrations ≥100 mg/dL. Remarkable hematocrit influence within the labeled hematocrit range was obtained in two systems with the tested reagent system lot. Adequate SMBG systems should be carefully chosen by patients and their health care professionals, particularly for patients with increased and decreased hematocrit values.

Life- and person-centred help in Mecklenburg-Western Pomerania, Germany (DelpHi): study protocol for a randomised controlled trial

PubMed Central

2012-01-01

Background The provision of appropriate medical and nursing care for people with dementia is a major challenge for the healthcare system in Germany. New models of healthcare provision need to be developed, tested and implemented on the population level. Trials in which collaborative care for dementia in the primary care setting were studied have demonstrated its effectiveness. These studies have been conducted in different healthcare systems, however, so it is unclear whether these results extend to the specific context of the German healthcare system. The objective of this population-based intervention trial in the primary care setting is to test the efficacy and efficiency of implementing a subsidiary support system on a population level for persons with dementia who live at home. Methods and study design The study was designed to assemble a general physician-based epidemiological cohort of people above the age of 70 who live at home (DelpHi cohort). These people are screened for eligibility to participate in a trial of dementia care management (DelpHi trial). The trial is a cluster-randomised, controlled intervention trial with two arms (intervention and control) designed to test the efficacy and efficiency of implementing a subsidiary support system for persons with dementia who live at home. This subsidiary support system is initiated and coordinated by a dementia care manager: a nurse with dementia-specific qualifications who delivers the intervention according to a systematic, detailed protocol. The primary outcome is quality of life and healthcare for patients with dementia and their caregivers. This is a multidimensional outcome with a focus on four dimensions: (1) quality of life, (2) caregiver burden, (3) behavioural and psychological symptoms of dementia and (4) pharmacotherapy with an antidementia drug and prevention or suspension of potentially inappropriate medication. Secondary outcomes include the assessment of dementia syndromes, activities of daily living, social support health status, utilisation of health care resources and medication. Discussion The results will provide evidence for specific needs in ambulatory care for persons with dementia and will show effective ways to meet those needs. Qualification requirements will be evaluated, and the results will help to modify existing guidelines and treatment paths. Trial registration NCT01401582 PMID:22575023

Measuring Patients' Experience of Rehabilitation Services Across the Care Continuum. Part I: A Systematic Review of the Literature.

2016-01-01

To identify empirically tested survey instruments designed to measure patient experience across a rehabilitative care system. A comprehensive search was conducted of the MEDLINE (PubMed), CINAHL (EBSCO), and PsycINFO (APA PsycNET) databases from 2004 to 2014. Further searches were conducted in relevant journals and the reference lists of the final accepted articles. Of 2472 articles identified, 33 were selected for inclusion and analysis. Articles were excluded if they were unrelated to rehabilitative care, were anecdotal or descriptive reports, or had a veterinary, mental health, palliative care, dental, or pediatric focus. Four reviewers performed the screening process. Interrater reliability was confirmed through 2 rounds of title review (30 articles each) and 1 round of abstract review (10 articles), with an average κ score of .69. Data were extracted related to the instrument, study setting, and patient characteristics, including treated disease, type of rehabilitation (eg, occupational or physical therapy), methodology, sample size, and level of evidence. There were 25 discrete measurement instruments identified in the 33 articles evaluated. Seven of the instruments originated outside of the rehabilitative care sector, and only 1 measured service experience across the care continuum. As providers move to integrate rehabilitative care across the continuum from hospital to home, patients experience a system of care. Research is required to develop psychometrically tested instruments that measure patients' experience across a rehabilitative system. Copyright © 2016 American Congress of Rehabilitation Medicine.

Economic Evidence and Point-of-Care Testing

PubMed Central

St John, Andrew; Price, Christopher P

2013-01-01

Health economics has been an established feature of the research, policymaking, practice and management in the delivery of healthcare. However its role is increasing as the cost of healthcare begins to drive changes in most healthcare systems. Thus the output from cost effectiveness studies is now being taken into account when making reimbursement decisions, e.g. in Australia and the United Kingdom. Against this background it is also recognised that the health economic tools employed in healthcare, and particularly the output from the use of these tools however, are not always employed in the routine delivery of services. One of the notable consequences of this situation is the poor record of innovation in healthcare with respect to the adoption of new technologies, and the realisation of their benefits. The evidence base for the effectiveness of diagnostic services is well known to be limited, and one consequence of this has been a very limited literature on cost effectiveness. One reason for this situation is undoubtedly the reimbursement strategies employed in laboratory medicine for many years, simplistically based on the complexity of the test procedure, and the delivery as a cost-per-test service. This has proved a disincentive to generate the required evidence, and little effort to generate an integrated investment and disinvestment business case, associated with care pathway changes. Point-of-care testing creates a particularly challenging scenario because, on the one hand, the unit cost-per-test is larger through the loss of the economy of scale offered by automation, whilst it offers the potential of substantial savings through enabling rapid delivery of results, and reduction of facility costs. This is important when many health systems are planning for complete system redesign. We review the literature on economic assessment of point-of-care testing in the context of these developments.

Health care reform presents academic health centers with an opportunity to test new systems of care, such as accountable care organizations (ACOs), that are intended to improve patients' health and well-being, mitigate the anticipated shortage in primary care providers, and bend the cost curve. In its ongoing efforts to develop an ACO, the Robert Wood Johnson Medical School, an academic health center, has found helpful a rapidly evolving competitive environment and insurers willing to experiment with new models of care. But the center has also encountered six types of barriers: conceptual, financial, cultural, regulatory, organizational, and historical. How this academic health center has faced these barriers offers valuable lessons to other health systems engaged in creating ACOs.

Explaining public satisfaction with health-care systems: findings from a nationwide survey in China.

To identify factors associated with health-care system satisfaction in China. Recent research suggests that socio-demographic characteristics, self-reported health, income and insurance, ideological beliefs, health-care utilization, media use and perceptions of services may affect health-care system satisfaction, but the relative importance of these factors is poorly understood. New data from China offer the opportunity to test theories about the sources of health-care system satisfaction. Stratified nationwide survey sample analysed using multilevel logistic regression. 3680 Chinese adults residing in family dwellings between 1 November 2012 and 17 January 2013. Satisfaction with the way the health-care system in China is run. We find only weak associations between satisfaction and socio-demographic characteristics, self-reported health and income. We do, however, find that satisfaction is strongly associated with having insurance and belief in personal responsibility for meeting health-care costs. We also find it is negatively associated with utilization, social media use, perceptions of access as unequal and perceptions of service providers as unethical. To improve satisfaction, Chinese policymakers - and their counterparts in countries with similar health-care system characteristics - should improve insurance coverage and the quality of health services, and tackle unethical medical practices. © 2015 The Authors.

Iwatani, Yoshinori

The dynamic healthcare environment of Japan, including the rapidly aging population and the requirement of highly sophisticated and diverse medical care, induces strict financial conditions and increases the number of those seeking medical care. Therefore, medical professionals are now required to provide safe and effective medical care with limited medical resources. Recently, Japanese medical institutions have introduced the total quality management system, which was developed for better business management, to promote safe and effective management. However, there are two major drawbacks with the introduction of this system in the sector of medical care in Japan. First, the standardization of medical skills of medical professionals is greatly affected due to the presence of different education systems for the same medical profession except for medical doctors and pharmacologists. The education system for major medical professionals, such as nurses and medical and radiological technologists, must be standardized based on the university norms. Second, the knowledge-creating process among the medical professionals has been associated with many problems. The specialized fields are quite different among medical professionals. Therefore, common specialized fields must be established among major medical professions based on the specialization of medical doctors to promote their communication and better understanding. Considering the roles of medical professionals in medical care, medical doctors and nurses are the most responsible for monitoring, assessing, and guaranteeing the safety of medical care, and medical and radiological technologists are the most responsible for effective medical care. The current medical technologists are not only required to carry out clinical laboratory tests, but also be proactive and positive as well as have marked problem-solving abilities. They are expected to improve the diagnostic test systems in medical institutes for medical doctors and patients, resulting in the highest level of management efficiency. For the development of such medical technologists, university education, specialist capabilities in medical technology and clinical laboratory diagnostics, and a research capability are essential. Thus, it is crucial for clinical laboratory physicians and the Japanese medical care system of the 21st century to urgently develop such an education system.

Abstract This article describes the design, development, and testing of the Health Care Safety Hotline, a prototype consumer reporting system for patient safety events. The prototype was designed and developed with ongoing review by a technical expert panel and feedback obtained during a public comment period. Two health care delivery organizations in one metropolitan area collaborated with the researchers to demonstrate and evaluate the system. The prototype was deployed and elicited information from patients, family members, and caregivers through a website or an 800 phone number. The reports were considered useful and had little overlap with information received by the health care organizations through their usual risk management, customer service, and patient safety monitoring systems. However, the frequency of reporting was lower than anticipated, suggesting that further refinements, including efforts to raise awareness by actively soliciting reports from subjects, might be necessary to substantially increase the volume of useful reports. It is possible that a single technology platform could be built to meet a variety of different patient safety objectives, but it may not be possible to achieve several objectives simultaneously through a single consumer reporting system while also establishing trust with patients, caregivers, and providers.

Pharmacogenomic clinical decision support systems (CDSS) have the potential to help overcome some of the barriers for translating pharmacogenomic knowledge into clinical routine. Before developing a prototype it is crucial for developers to know which pharmacogenomic CDSS features and user-system interactions have yet been developed, implemented and tested in previous pharmacogenomic CDSS efforts and if they have been successfully applied. We address this issue by providing an overview of the designs of user-system interactions of recently developed pharmacogenomic CDSS. We searched PubMed for pharmacogenomic CDSS published between January 1, 2012 and November 15, 2016. Thirty-two out of 118 identified articles were summarized and included in the final analysis. We then compared the designs of user-system interactions of the 20 pharmacogenomic CDSS we had identified. Alerts are the most widespread tools for physician-system interactions, but need to be implemented carefully to prevent alert fatigue and avoid liabilities. Pharmacogenomic test results and override reasons stored in the local EHR might help communicate pharmacogenomic information to other internal care providers. Integrating patients into user-system interactions through patient letters and online portals might be crucial for transferring pharmacogenomic data to external health care providers. Inbox messages inform physicians about new pharmacogenomic test results and enable them to request pharmacogenomic consultations. Search engines enable physicians to compare medical treatment options based on a patient's genotype. Within the last 5 years, several pharmacogenomic CDSS have been developed. However, most of the included articles are solely describing prototypes of pharmacogenomic CDSS rather than evaluating them. To support the development of prototypes further evaluation efforts will be necessary. In the future, pharmacogenomic CDSS will likely include prediction models to identify patients who are suitable for preemptive genotyping.

Chronic non-communicable diseases, predominantly diabetes and cardiovascular disease are a major public health problem globally. The chronicity of these diseases necessitates a restructuring of healthcare to address the multidisciplinary, sustained care including psychosocial support and development of self-management skills. Primary healthcare with elements of the chronic-care model provides the best opportunity for engagement with the health system. In this review, the authors discuss aspects of primary healthcare for management of diabetes and hypertension and innovations such as mobile-phone messaging, web-based registries, computer-based decision support systems and multifaceted health professionals in the care team among others that are being tested to improve the quality of care for these diseases in high, middle and low-income countries. The goal of quality care for diabetes and hypertension demands innovation within the realities of health systems both in high as well as low and middle-income countries.

Centers for medicare and medicaid services: using an episode-based payment model to improve oncology care.

Cancer is a medically complex and expensive disease with costs projected to rise further as new treatment options increase and the United States population ages. Studies showing significant regional variation in oncology quality and costs and model tests demonstrating cost savings without adverse outcomes suggest there are opportunities to create a system of oncology care in the US that delivers higher quality care at lower cost. The Centers for Medicare and Medicaid Services (CMS) have designed an episode-based payment model centered around 6 month periods of chemotherapy treatment. Monthly per-patient care management payments will be made to practices to support practice transformation, including additional patient services and specific infrastructure enhancements. Quarterly reporting of quality metrics will drive continuous quality improvement and the adoption of best practices among participants. Practices achieving cost savings will also be eligible for performance-based payments. Savings are expected through improved care coordination and appropriately aligned payment incentives, resulting in decreased avoidable emergency department visits and hospitalizations and more efficient and evidence-based use of imaging, laboratory tests, and therapeutic agents, as well as improved end of life care. New therapies and better supportive care have significantly improved cancer survival in recent decades. This has come at a high cost, with cancer therapy consuming $124 billion in 2010. CMS has designed an episode-based model of oncology care that incorporates elements from several successful model tests. By providing care management and performance based payments in conjunction with quality metrics and a rapid learning environment, it is hoped that this model will demonstrate how oncology care in the US can transform into a high value, high quality system.

To describe the history and evolution of the collaborative depression care model and new research aimed at enhancing dissemination. Four keynote speakers from the 2009 NIMH Annual Mental Health Services Meeting collaborated in this article in order to describe the history and evolution of collaborative depression care, adaptation of collaborative care to new populations and medical settings, and optimal ways to enhance dissemination of this model. Extensive evidence across 37 randomized trials has shown the effectiveness of collaborative care vs. usual primary care in enhancing quality of depression care and in improving depressive outcomes for up to 2 to 5 years. Collaborative care is currently being disseminated in large health care organizations such as the Veterans Administration and Kaiser Permanente, as well as in fee-for-services systems and federally funded clinic systems of care in multiple states. New adaptations of collaborative care are being tested in pediatric and ob-gyn populations as well as in populations of patients with multiple comorbid medical illnesses. New NIMH-funded research is also testing community-based participatory research approaches to collaborative care to attempt to decrease disparities of care in underserved minority populations. Collaborative depression care has extensive research supporting the effectiveness of this model. New research and demonstration projects have focused on adapting this model to new populations and medical settings and on studying ways to optimally disseminate this approach to care, including developing financial models to incentivize dissemination and partnerships with community populations to enhance sustainability and to decrease disparities in quality of mental health care.

Currently, informal caregivers provide the bulk of care for persons with cognitive impairment who live in the home, often at significant cost in terms of their own physical, mental, and emotional health. This is a report of the development of a home monitoring system, CareWatch, designed for use in homes of persons with cognitive impairment such as Alzheimer’s disease. The purpose of CareWatch is to prevent unattended home exits, particularly during the night, and to improve caregiver sleep. We report on the development of CareWatch and on 2 clinical trials underway to test its effectiveness in the home setting. PMID:20454554

The value of health information technology (IT) ultimately depends on end users accepting and appropriately using it for patient care. This study examined pediatric intensive care unit nurses' perceptions, acceptance, and use of a novel health IT, the Large Customizable Interactive Monitor. An expanded technology acceptance model was tested by applying stepwise linear regression to data from a standardized survey of 167 nurses. Nurses reported low-moderate ratings of the novel IT's ease of use and low to very low ratings of usefulness, social influence, and training. Perceived ease of use, usefulness for patient/family involvement, and usefulness for care delivery were associated with system satisfaction (R 2  = 70%). Perceived usefulness for care delivery and patient/family social influence were associated with intention to use the system (R 2  = 65%). Satisfaction and intention were associated with actual system use (R 2  = 51%). The findings have implications for research, design, implementation, and policies for nursing informatics, particularly novel nursing IT. Several changes are recommended to improve the design and implementation of the studied IT.

Fundamental reform of payment for adult primary care: comprehensive payment for comprehensive care.

Goroll, Allan H; Berenson, Robert A; Schoenbaum, Stephen C; Gardner, Laurence B

2007-03-01

Primary care is essential to the effective and efficient functioning of health care delivery systems, yet there is an impending crisis in the field due in part to a dysfunctional payment system. We present a fundamentally new model of payment for primary care, replacing encounter-based imbursement with comprehensive payment for comprehensive care. Unlike former iterations of primary care capitation (which simply bundled inadequate fee-for-service payments), our comprehensive payment model represents new investment in adult primary care, with substantial increases in payment over current levels. The comprehensive payment is directed to practices to include support for the modern systems and teams essential to the delivery of comprehensive, coordinated care. Income to primary physicians is increased commensurate with the high level of responsibility expected. To ensure optimal allocation of resources and the rewarding of desired outcomes, the comprehensive payment is needs/risk-adjusted and performance-based. Our model establishes a new social contract with the primary care community, substantially increasing payment in return for achieving important societal health system goals, including improved accessibility, quality, safety, and efficiency. Attainment of these goals should help offset and justify the costs of the investment. Field tests of this and other new models of payment for primary care are urgently needed.

Primary care is essential to the effective and efficient functioning of health care delivery systems, yet there is an impending crisis in the field due in part to a dysfunctional payment system. We present a fundamentally new model of payment for primary care, replacing encounter-based imbursement with comprehensive payment for comprehensive care. Unlike former iterations of primary care capitation (which simply bundled inadequate fee-for-service payments), our comprehensive payment model represents new investment in adult primary care, with substantial increases in payment over current levels. The comprehensive payment is directed to practices to include support for the modern systems and teams essential to the delivery of comprehensive, coordinated care. Income to primary physicians is increased commensurate with the high level of responsibility expected. To ensure optimal allocation of resources and the rewarding of desired outcomes, the comprehensive payment is needs/risk-adjusted and performance-based. Our model establishes a new social contract with the primary care community, substantially increasing payment in return for achieving important societal health system goals, including improved accessibility, quality, safety, and efficiency. Attainment of these goals should help offset and justify the costs of the investment. Field tests of this and other new models of payment for primary care are urgently needed. PMID:17356977

It is very important to establish a clinical testing system which is not only prompt, simple and accurate but also safe for the patients and medical staff in the operating room, emergency room and intensive care unit. In our institution an i-STAT portable blood gas analyser has been widely used for point of care testing in all the operating rooms. This clinical testing system has been upgraded by adding an i-STAT communication protocol to our online data management system. The analysed data transmitted by the i-STAT as an infrared signal is transformed to an electronic signal through the IR link and sent to the central data station (CDS) via RS232C. The data received by the CDS is then sent to the upper grade computer system where the data is recorded on the hard disk. One advantage of this system is that it is connected to the hospital computer system. Not only does this new system meet the need for accurate, safe, effective and economical laboratory testing, but also retrospective and multifactorial analysis of intraoperative events can be easily carried out. In the future this system can be applied to telemedicine through the Internet and contribute to the treatment of critically ill patients.

The need for efficient retention in HIV care is more evident than ever because of the expansion of earlier ART initiation and the shift towards 'Test and Treat'. This study assesses factors affecting participation in the HIV care cascade among people living with HIV (PLHIV) in the Asia-Pacific Region. A total of 7843 PLHIV aged 18-50 years were recruited using targeted and venue-based sampling between October 1, 2012, and May 31, 2013, across 59 sites in 7 countries (Bangladesh, Indonesia, Lao People's Democratic Republic (Lao PDR), Nepal, Pakistan, Philippines and Vietnam). Statistically significant associations between demographic and health system determinants, and various steps in the HIV care cascade were computed using a generalized structural equation model. A high proportion of PLHIV (40-51%) presented late for HIV care and delayed linkage to care in all seven countries. However, once PLHIV enrolled in care, retention in the various steps of the care cascade including adherence to antiretroviral treatment (ART) was satisfactory. The proportion still engaged in HIV care at 36 months post HIV diagnosis, varied from 78% in Nepal to >90% in Lao PDR. Similarly, the proportion of ART initiation who also were adherent to ART ranged from 91% in Bangladesh to >95% in Philippines/ Vietnam and from 70% in Lao PDR to 89% in the Philippines respectively. The following factors enhanced the likelihood of ART initiation and high adherence to HIV care and ART: good client-provider communication, high HIV treatment literacy, a referral from a health worker and TB/HIV co-infection. The following barriers were identified: young age, sex work, imprisonment, transgender identity, illiteracy, rural residence, alcohol/ injecting drug use, perceived poor health status, lack of health insurance, fear of confidentiality breach, self-referral for HIV testing, and public hospital as the place of HIV diagnosis. HIV programme planners should ensure easy access to HIV testing and earlier linkage to HIV care among PLHIV. In addition, multiple socio-economic and health systems barriers need to be addressed along the HIV care cascade to reach the UNAIDS 90-90-90 target in the Asia-Pacific region.

Engineering tests were conducted in order to characterize overall system performance and component efficiencies within the system environment. A dynamometer was used in order to minimize the ambient effects and large uncertainties present in track testing. Extensive test requirements were defined and procedures were carefully controlled in order to maintain a high degree of credibility. Limited track testing was performed in order to corroborate the dynamometer results. Test results include an energy flow analysis through the major subsystems and incorporate the aerodynamic and rolling losses under cyclic and various steady speed conditions. The major output from all relevant dynamometer and track tests is also included.

The transgender community experiences health care discrimination and approximately 1 in 4 transgender people were denied equal treatment in health care settings. Discrimination is one of the many factors significantly associated with health care utilization and delayed care. We assessed factors associated with delayed medical care due to discrimination among transgender patients, and evaluated the relationship between perceived provider knowledge and delayed care using Anderson's behavioral model of health services utilization. Multivariable logistic regression analysis was used to test whether predisposing, enabling, and health system factors were associated with delaying needed care for transgender women and transgender men. A sample of 3486 transgender participants who took part in the National Transgender Discrimination Survey in 2008 and 2009. Predisposing, enabling, and health system environment factors, and delayed needed health care. Overall, 30.8% of transgender participants delayed or did not seek needed health care due to discrimination. Respondents who had to teach health care providers about transgender people were 4 times more likely to delay needed health care due to discrimination. Transgender patients who need to teach their providers about transgender people are significantly more likely to postpone or not seek needed care. Systemic changes in provider education and training, along with health care system adaptations to ensure appropriate, safe, and respectful care, are necessary to close the knowledge and treatment gaps and prevent delayed care with its ensuing long-term health implications.

2006-06-01

This study focused on analysing costs per home health care nursing visit based on home health care nursing activities in medical institutes. The data was collected in three stages. First, the cost elements of home health care nursing services were collected and 31 home care nurses participated. Second, the workload and caseload of home care nursing activities were measured by the Easley-Storfjell Instrument(1997). Third, the opinions on improving the home health care nursing reimbursement system were collected by a nation-wide mailing survey from a total of 125 home care agencies. The cost of home health care nursing per visit was calculated as 50,626 won. This was composed of a basic visiting fee of 35,090 won (about 35 $) and travel fee of 15,536 won (about 15 $). The major problems of the home care nursing payment system were the low level of the cost per visit, no distinction between first visit and revisits, and the limitations in health insurance coverage for home health care nursing services. This study's results will contribute as a baseline for establishing policies for improvement of the home health care nursing cost and for applying a community-based visiting nursing service cost.

To evaluate and compare the quality of diabetes care in a large managed care system and fee-for-service payment system in Puerto Rico. This retrospective cross-sectional study assessed the adherence to standards of diabetes care in 1,687,202 subjects--226,210 from a fee-for-service population and 1,460,992 from a managed care group. Patients with diabetes mellitus were identified from insurance claims reports. Type of health-care provider, service location, number of visits, and laboratory utilization were also assessed. From the analysis, we identified 90,616 patients with diabetes (5.4% of the overall study group). Of these, 66,587 (73.5%) were found to have at least one encounter with a physician in a medical visit. Of the 66,586 patients with diabetes who visited a physician, only 4% were treated by an endocrinologist. General laboratory utilization was 34% for the entire population of patients with diabetes studied. In the group of patients with documented laboratory tests, 93% had a documented fasting blood glucose test; in contrast, hemoglobin A lc testing was performed in only 9% of the patients. The fee-for-service group had a higher rate of visits to medical specialists and general laboratory utilization, whereas the managed care group had a higher rate of hospital admissions and emergency department visits. The quality of diabetes management and the subsequent outcomes are related to patient and health-care provider adherence to standards of care. In this analysis, we found that patients and physicians are responsible for low compliance with recognized standards of diabetes care in Puerto Rico. The lack of adequate management will lead to increased mortality, development and severity of chronic complications, and increased emergency department utilization. Therefore, health-care providers and payers should find ways to achieve more effective promotion of adherence to accepted standards of care for patients with diabetes.

Social contract theory and just decision making: lessons from genetic testing for the BRCA mutations.

Decisions about funding health services are crucial to controlling costs in health care insurance plans, yet they encounter serious challenges from intellectual property protection--e.g., patents--of health care services. Using Myriad Genetics' commercial genetic susceptibility test for hereditary breast cancer (BRCA testing) in the context of the Canadian health insurance system as a case study, this paper applies concepts from social contract theory to help develop more just and rational approaches to health care decision making. Specifically, Daniel's and Sabin's "accountability for reasonableness" is compared to broader notions of public consultation, demonstrating that expert assessments in specific decisions must be transparent and accountable and supplemented by public consultation.

Perspectives on Pap Test Follow Up Care Among Rural Appalachian Women

2010-01-01

Approximately one to three quarters of women notified of abnormal Pap test results do not receive appropriate follow up care, dramatically elevating their risk for invasive cervical cancer (ICC). We explored barriers to/facilitators of follow up care for women in two counties in Appalachian Kentucky, where ICC incidence and mortality are significantly higher than the national average. In-depth interviews were conducted among 27 Appalachian women and seven local health department personnel. Those who had been told of an atypical Pap test result tended to have one of three reactions; (1) not alarmed and generally did not obtain follow-up care; (2) alarmed and obtained follow up care; or (3) alarmed, but did not obtain care. Each of these typologies appeared to be shaped by a differing set of three categories of influences: personal factors; procedure/provider/system factors; and ecological/community factors. Recommendations to increase appropriate follow up care included pursuing research on explanations for these typologies and developing tailored interventions specific to women in each of the response types.

Integrating the Healthcare Enterprise-Japan (IHE-J) was established in Japan in 2001 and has been working to standardize health information and make it accessible on the basis of the fundamental Integrating Healthcare Enterprise (IHE) specifications. However, because specialized operations are used in nuclear medicine tests, online sharing of patient information and test order information from the order entry system as shown by the scheduled workflow (SWF) is difficult, making information inconsistent throughout the facility and uniform management of patient information impossible. Therefore, we examined the basic design (subsystem design) for order entry systems, which are considered an important aspect of information management for nuclear medicine tests and needs to be consistent with the system used throughout the rest of the facility. There are many items that are required by the subsystem when setting up an order entry system for nuclear medicine tests. Among these items, those that are the most important in the order entry system are constructed using exclusion settings, because of differences in the conditions for using radiopharmaceuticals and contrast agents and appointment frame settings for differences in the imaging method and test items. To establish uniform management of patient information for nuclear medicine tests throughout the facility, it is necessary to develop an order entry system with exclusion settings and appointment frames as standard features. Thereby, integration of health information with the Radiology Information System (RIS) or Picture Archiving Communication System (PACS) based on Digital Imaging Communications in Medicine (DICOM) standards and real-time health care assistance can be attained, achieving the IHE agenda of improving health care service and efficiently sharing information.

Safe use of electronic health records and health information technology systems: trust but verify.

We will provide a context to health information technology systems (HIT) safety hazards discussions, describe how electronic health record-computer prescriber order entry (EHR-CPOE) simulation has already identified unrecognized hazards in HIT on a national scale, helping make EHR-CPOE systems safer, and we make the case for all stakeholders to leverage proven methods and teams in HIT performance verification. A national poll of safety, quality improvement, and health-care administrative leaders identified health information technology safety as the hazard of greatest concern for 2013. Quality, HIT, and safety leaders are very concerned about technology performance risks as addressed in the Health Information Technology and Patient Safety report of the Institute of Medicine; and these are being addressed by the Office of the National Coordinator of HIT of the U.S. Dept. of Human Services in their proposed plans. We describe the evolution of postdeployment testing of HIT performance, including the results of national deployment of Texas Medical Institute of Technology's electronic health record computer prescriber order entry (TMIT EHR-CPOE) Flight Simulator verification test that is addressed in these 2 reports, and the safety hazards of concern to leaders. A global webinar for health-care leaders addressed the top patient safety hazards in the areas of leadership, practices, and technologies. A poll of 76 of the 221 organizations participating in the webinar revealed that HIT hazards were the participants' greatest concern of all 30 hazards presented. Of those polled, 89% rated HIT patient/data mismatches in EHRs and HIT systems as a 9 or 10 on a scale of 1 to 10 as a hazard of great concern. Review of a key study of postdeployment testing of the safety performance of operational EHR systems with CPOE implemented in 62 hospitals, using the TMIT EHR-CPOE simulation tool, showed that only 53% of the medication orders that could have resulted in fatalities were detected. The study also showed significant variability in the performance of specific EHR vendor systems, with the same vendor product scoring as high as a 75% detection score in one health-care organization, and the same vendor system scoring below 10% in another health-care organization. HIT safety hazards should be taken very seriously, and the need for proven, robust, and regular postdeployment performance verification measurement of EHR system operations in every health-care organization is critical to ensure that these systems are safe for every patient. The TMIT EHR-CPOE flight simulator is a well-tested and scalable tool that can be used to identify performance gaps in EHR and other HIT systems. It is critical that suppliers, providers, and purchasers of health-care partner with HIT stakeholders and leverage the existing body of work, as well as expert teams and collaborative networks to make care safer; and public-private partnerships to accelerate safety in HIT. A global collaborative is already underway incorporating a "trust but verify" philosophy.

Background The testing and result communication process in primary care is complex. Its successful completion relies on the coordinated efforts of a range of staff in primary care and external settings working together with patients. Despite the importance of diagnostic testing in provision of care, this complexity renders the process vulnerable in the face of increasing demand, stretched resources and a lack of supporting guidance. Methods We conducted a series of focus groups with patients and staff across four primary care practices using process-improvement strategies to identify and understand areas where either unnecessary delay is introduced, or the process may fail entirely. We then worked with both patients and staff to arrive at practical strategies to improve the current system. Results A total of six areas across the process were identified where improvements could be introduced. These were: (1) delay in phlebotomy, (2) lack of a fail-safe to ensure blood tests are returned to practices and patients, (3) difficulties in accessing results by telephone, (4) role of non-clinical staff in communicating results, (5) routine communication of normal results and (6) lack of a protocol for result communication. Conclusions A number of potential failures in testing and communicating results to patients were identified, and some specific ideas for improving existing systems emerged. These included same-day phlebotomy sessions, use of modern technology methods to proactively communicate routine results and targeted training for receptionists handling sensitive data. There remains an urgent need for further work to test these and other potential solutions. PMID:26251507

Early diagnosis of human immunodeficiency virus (HIV) infection and initiation of antiretroviral treatment (ART) improves health outcomes and prevents HIV transmission. Before 2010, HIV testing was available to inmates in the California state prison system upon request. In 2010, the California Correctional Health Care Services (CCHCS) integrated HIV opt-out screening into the health assessment for inmates entering California state prisons. Under this system, a medical care provider informs the inmate that an HIV test is routinely done, along with screening for sexually transmitted, communicable, and vaccine-preventable diseases, unless the inmate specifically declines the test. During 2012-2013, CCHCS, the California Department of Public Health, and CDC evaluated HIV screening, rates of new diagnoses, linkage to and retention in care, ART response, and post-release linkage to care among California prison inmates. All prison inmates are processed through one of eight specialized reception center facilities, where they undergo a comprehensive evaluation of their medical needs, mental health, and custody requirements for placement in one of 35 state prisons. Among 17,436 inmates who entered a reception center during April-September 2012, 77% were screened for HIV infection; 135 (1%) tested positive, including 10 (0.1%) with newly diagnosed infections. Among the 135 HIV-positive patient-inmates, 134 (99%) were linked to care within 90 days of diagnosis, including 122 (91%) who initiated ART. Among 83 who initiated ART and remained incarcerated through July 2013, 81 (98%) continued ART; 71 (88%) achieved viral suppression (<200 HIV RNA copies/mL). Thirty-nine patient-inmates were released on ART; 12 of 14 who were linked to care within 30 days of release were virally suppressed at that time. Only one of nine persons with a viral load test conducted between 91 days and 1 year post-release had viral suppression. Although high rates of viral suppression were achieved in prison, continuity of care in the community remains a challenge. An infrastructure for post-release linkage to care is needed to help ensure sustained HIV disease control.

Performance of a fail-safe system to follow up abnormal mammograms in primary care.

Missed and delayed breast cancer diagnoses are major sources of potential harm to patients and medical malpractice liability in the United States. Follow-up of abnormal mammogram results is an essential but challenging component of safe breast care. To explore the value of an inexpensive method to follow up abnormal test results, we examined a paper-based fail-safe system. We examined a fail-safe system used to follow up abnormal mammograms at a primary care practice at an urban teaching hospital. We analyzed all abnormal mammogram reports and clinicians' responses to follow-up reminders. We characterized potential lapses identified in this system and used regression models to identify patient, provider, and test result characteristics associated with such lapses. Clinicians responded to fail-safe reminders for 92% of 948 abnormal mammograms. Clinicians reported that they were unaware of the abnormal result in 8% of cases and that there was no follow-up plan in place for 3% of cases. Clinicians with more years of experience were more likely to be aware of the abnormal result (odds of being unaware per incremental year in practice, 0.92; 95% confidence interval, 0.88-0.97) and were more likely to have a follow-up plan. A paper-based fail-safe system for abnormal mammograms is feasible in a primary care practice. However, special care is warranted to ensure full clinician adherence and address staff transitions and trainee-related issues.

Minimally invasive breast biopsy (MIBB) is the procedure of choice for diagnosing breast lesions indeterminate for malignancy. Multihospital health care systems face challenges achieving systemwide adherence to standardized guidelines among surgeons with varying practice patterns. This study tested whether providing individual feedback about surgeons' use of MIBB to diagnose breast malignancies improved quality metric adherence across a large health care organization. We conducted a prospective matched-pairs study to test differences (or lack of agreement) between periods before and after intervention. All analytical cases of primary breast cancer diagnosed during 2011 (period 1) and from July 2012 to June 2013 (period 2) across a multihospital health care system were reviewed for initial diagnosis by MIBB or open surgical biopsy. Open surgical biopsy was considered appropriate care only if MIBB could not be performed for reasons listed in the American Society of Breast Surgeons' quality measure for preoperative diagnosis of breast cancer. Individual and systemwide results of adherence to the MIBB metric during period 1 were sent to each surgeon in June 2012 and were later compared with period 2 results using McNemar's test of marginal homogeneity for matched binary responses. Forty-six surgeons were evaluated on use of MIBB to diagnose breast cancer. In period 1, metric adherence for 100% of cases was achieved by 37 surgeons, for a systemwide 100% compliance rate of 80.4%. After notification of individual performance, 44 of 46 surgeons used MIBB solely or otherwise appropriate care to diagnose breast cancer, which improved systemwide compliance to 95.7%. Providing individual and systemwide performance results to surgeons can increase self-awareness of practice patterns when diagnosing breast cancer, leading to standardized best-practice care across a large health care organization.

2008-09-01

This guideline provides a framework for the arrangement of point-of-care testing (POCT) services, previously known as near patient testing (patient self-testing not covered). POCT is defined as any analytical test performed outside the laboratory. Primary users are often non-laboratory healthcare workers. The guidance applies to units within hospitals as well as general practioner surgeries, community clinics and pharmacies. The head of the haematology laboratory or a point of care coordinator must take responsibility for all aspects of the POCT service, including quality and training. Depending on the size and nature of the POCT practice, a local POCT manager may also be required. Equipment selected should have received a successful independent performance evaluation. If an independent evaluation has not been performed the purchaser should assess the device according to the protocol in this document. POCT devices should generate results that are comparable to those of the local laboratory. An accredited external quality assessment programme and internal quality control system must be established. Manufacturers promoting POCT devices designed for non-laboratory sites, e.g. pharmacies, should undertake training and annual competency assessment, perhaps using a web-based system. A diagram to illustrate the stages for the implementation of a POCT service is illustrated.

Development and testing of the Multidimensional Trust in Health Care Systems Scale.

Egede, Leonard E; Ellis, Charles

2008-06-01

To describe the development and psychometric testing of the Multidimensional Trust in Health Care Systems Scale (MTHCSS). Scale development occurred in 2 phases. In phase 1, a pilot instrument with 70 items was generated from the review of the trust literature, focus groups, and expert opinion. The 70 items were pilot tested in a sample of 256 students. Exploratory factor analysis was used to derive an orthogonal set of correlated factors. In phase 2, the final scale was administered to 301 primary care patients to assess reliability and validity. Phase 2 participants also completed validated measures of patient-centered care, health locus of control, medication nonadherence, social support, and patient satisfaction. In phase 1, a 17-item scale (MTHCSS) was developed with 10 items measuring trust in health care providers, 4 items measuring trust in health care payers, and 3 items measuring trust in health care institutions. In phase 2, the 17-item MTHCSS had a mean score of 63.0 (SD 8.8); the provider subscale had a mean of 40.0 (SD 6.2); the payers subscale had a mean of 12.8 (SD 3.0); and the institutions subscale had a mean of 10.3 (SD 2.1). Cronbach's alpha for the MTHCSS was 0.89 and 0.92, 0.74, and 0.64 for the 3 subscales. The MTHCSS was significantly correlated with patient-centered care (r = .22 to .62), locus of control-chance (r = .42), medication nonadherence (r = -.22), social support (r = .25), and patient satisfaction (r = .67). The MTHCSS is a valid and reliable instrument for measuring the 3 objects of trust in health care and is correlated with patient-level health outcomes.

Follow-up of gestational diabetes mellitus in an urban safety net hospital: missed opportunities to launch preventive care for women.

Our study assessed the follow-up of gestational diabetes mellitus (GDM) in the postpartum period among a racially and ethnically diverse group of women receiving care in a major urban medical center. We conducted cross-sectional analysis of clinical and administrative data on women aged 18-44 years who gave birth at Boston Medical Center (BMC) between 2003 and 2009, had GDM, and used BMC for regular care. We calculated the rate of glucose testing by 70 days and by 180 days after delivery and used logistic regression to assess the predictors of testing. By 6 months postpartum, only 23.4% of GDM-affected women received any kind of glucose test. Among these, over half had been completed by 10 weeks but only 29% were the recommended oral glucose tolerance test (OGTT). After accounting for sociodemographic and health service factors, women aged ≤ 35 years of age and women with a family practice provider were significantly less likely to be tested than their counterparts (odds ratio [OR] 0.51; 95% confidence interval [CI] 0.32, 0.83 and OR 0.36; 95% CI 0.19, 0.71 respectively). Women who attended a primary care visit within 180 days after birth had three times higher odds of being tested than those without such a visit (OR 3.10; 95% CI 1.97, 4.87). Despite widely disseminated clinical guidelines, postpartum glucose testing rates are exceedingly low, marking a critical missed opportunity to launch preventive care for women at high risk of type 2 DM. Failed follow-up of GDM by providers of prenatal and postpartum care also reflects a broader systems failure: the absence of a well-supported transition from pregnancy care to ongoing primary care for women.

However, several studies have shown that spirometry quality in primary care is not ideal, with risks of misdiagnosis. Our objective was to assess the feasibility and performance of a telemedicine-based training and quality assurance program for forced spirometry in primary care. The two phases included (1) a 9-month pilot study involving 15 centers, in which spirometry tests were assessed by the Basque Office for Health Technology Assessment, and (2) the introduction of the program to all centers in the Public Basque Health Service. Technicians first received 4 h of training, and, subsequently, they sent all tests to the reference laboratory using the program. Quality assessment was performed in accordance with clinical guidelines (A and B, good; C-F, poor). In the first phase, 1,894 spirometry tests were assessed, showing an improvement in quality: acceptable quality tests increased from 57% at the beginning to 78% after 6 months and 83% after 9 months (p<0.001). In the second phase, 7,200 spirometry tests were assessed after the inclusion of 36 additional centers, maintaining the positive trend (61%, 87%, and 84% at the same time points; p<0.001). (1) The quality of spirometry tests improved in all centers. (2) The program provides a tool for transferring data that allows monitoring of its quality and training of technicians who perform the tests. (3) This approach is useful for improving spirometry quality in the routine practice of a public health system.

The availability of new tools able to support patient monitoring and personalized care may substantially improve the quality of chronic disease management. A personalized healthcare pathway (PHP) has been developed for diabetes disease management and integrated into an information and communication technology system to accomplish a shift from organization-centered care to patient-centered care. A small-scale exploratory study was conducted to test the platform. Preliminary results are presented that shed light on how the PHP influences system usage and performance outcomes.

Medical errors from communication failures are enormous during the perioperative period of cardiac surgical patients. As caregivers change shifts or surgical patients change location within the hospital, key information is lost or misconstrued. After a baseline cognitive study of information need and caregiver workflow, we implemented an advanced clinical decision support tool of intelligent agents, medical logic modules, and text generators called the "Inference Engine" to summarize individual patient's raw medical data elements into procedural milestones, illness severity, and care therapies. The system generates two displays: 1) the continuum of care, multimedia abstract generation of intensive care data (MAGIC)-an expert system that would automatically generate a physician briefing of a cardiac patient's operative course in a multimodal format; and 2) the isolated point in time, "Inference Engine"-a system that provides a real-time, high-level, summarized depiction of a patient's clinical status. In our studies, system accuracy and efficacy was judged against clinician performance in the workplace. To test the automated physician briefing, "MAGIC," the patient's intraoperative course, was reviewed in the intensive care unit before patient arrival. It was then judged against the actual physician briefing and that given in a cohort of patients where the system was not used. To test the real-time representation of the patient's clinical status, system inferences were judged against clinician decisions. Changes in workflow and situational awareness were assessed by questionnaires and process evaluation. MAGIC provides 200% more information, twice the accuracy, and enhances situational awareness. This study demonstrates that the automation of clinical processes through AI methodologies yields positive results.

How can a formulator have confidence that a preservative system will perform as expected under adverse conditions? Extreme conditions that can lead to the development of "off odors" in the product can be a serious challenge for companies providing home care products in the global market. Formulation and stability testing occur under controlled parameters that simulate limited environmental conditions and microbial challenges are typically performed with a standard inoculum level. While this is an acceptable and dependable process, it does not necessarily assess how well a preservative system can perform under extreme environmental conditions or against unusually high levels of bacterial challenges. This is especially true when formulations are diluted and stored by the end-user. By modifying microbial challenge testing of a liquid dishwashing product to include unexpected dilution schemes, increased microbial assaults, and elevated temperatures, a pattern of preservative efficacy was established. The resulting approach proved to be a useful tool when developing use directions, recommended dilution levels, the overall surfactant system, preservative type, and storage restrictions.

Are the kids really all right? Direct-to-consumer genetic testing in children: are company policies clashing with professional norms?

The genetic testing of minors within the direct-to-consumer (DTC) genetic testing (GT) context has been given relatively little attention. The issue of testing healthy children for diseases that would only develop in adulthood raises many important ethical, legal and social issues. As genetic testing is now available outside of the traditional health care system, often without even the intermediate of a health care professional, we surveyed 37 DTC GT companies regarding their policies for testing in children. Although the response rate is relatively low (35%, 13/37), our findings reveal that a clear majority of companies do perform genetic testing in minors. As such, companies testing for adult onset diseases are acting in contradiction of established professional guidelines, which state, among others, that, for predictive genetic testing, the availability of therapeutic or preventive measures is necessary for testing to be performed in asymptomatic minors. The community of stakeholders in children's health care and genetic testing should, therefore, decide which standards need to be upheld by DTC GT companies and ensure that these are met.

SFR test fixture for hemispherical and hyperhemispherical camera systems

2017-08-01

Optical testing of camera systems in volume production environments can often require expensive tooling and test fixturing. Wide field (fish-eye, hemispheric and hyperhemispheric) optical systems create unique challenges because of the inherent distortion, and difficulty in controlling reflections from front-lit high resolution test targets over the hemisphere. We present a unique design for a test fixture that uses low-cost manufacturing methods and equipment such as 3D printing and an Arduino processor to control back-lit multi-color (VIS/NIR) targets and sources. Special care with LED drive electronics is required to accommodate both global and rolling shutter sensors.

Space Station Freedom's (SSF's) electric power system (EPS) hardware and software verification is performed at all levels of integration, from components to assembly and system level tests. Careful planning is essential to ensure the EPS is tested properly on the ground prior to launch. The results of the test performed on breadboard model hardware and analyses completed to date have been evaluated and used to plan for design qualification and flight acceptance test phases. These results and plans indicate the verification program for SSF's 75-kW EPS would have been successful and completed in time to support the scheduled first element launch.

Interest in improving quality and effectiveness is the primary driver for health information exchange efforts across a health care system to improve the provision of public health care services. The aim here was to describe and identify the impact of a regional health information exchange (HIE) using quantitative statistics for 2004-2008 in one hospital district in Finland. We conducted a comparative, longitudinal 5-year follow-up study to evaluate the utilization rates of HIE, and the impact on health care delivery outcomes. The selected outcomes were total laboratory tests, radiology examinations, appointments, emergency visits, and referrals. The HIE utilization rates increased annually in all 10 federations of municipalities, and the viewing of reference information increased steadily in each professional group over the 5-year study period. In these federations, a significant connection was found to the number of laboratory tests and radiology examinations, with a statistically significant increase in the number of viewed references and use of HIE. The higher the numbers of emergency visits and appointments, the higher the numbers of emergency referrals to specialized care, viewed references, and HIE usage among the groups of different health care professionals. There is increasing interest in HIE usage through regional health information system among health professionals to improve health care delivery regionally and bring information on the patient directly to care delivery. It will be important to study which changes in working methods in the service system are explained by RHIS. Also, the experiences of the change that has taken place should be studied among the different stakeholders, administrative representatives, and patients.

Oral anticoagulation monitoring has traditionally taken place in secondary care because of the need for a laboratory blood test, the international normalised ratio (INR). The development of reliable near patient testing (NPT) systems for INR estimation has facilitated devolution of testing to primary care. Patient self-management is a logical progression from the primary care model. This study will be the first to randomise non-selected patients in primary care, to either self-management or standard care. The study was a multi-centred randomised controlled trial with patients from 49 general practices recruited. Those suitable for inclusion were aged 18 or over, with a long term indication for oral anticoagulation, who had taken warfarin for at least six months. Patients randomised to the intervention arm attended at least two training sessions which were practice-based, 1 week apart. Each patient was assessed on their capability to undertake self management. If considered capable, they were given a near patient INR testing monitor, test strips and quality control material for home testing. Patients managed their own anticoagulation for a period of 12 months and performed their INR test every 2 weeks. Control patients continued with their pre-study care either attending hospital or practice based anticoagulant clinics. The methodology used in this trial will overcome concerns from previous trials of selection bias and relevance to the UK health service. The study will give a clearer understanding of the benefits of self-management in terms of clinical and cost effectiveness and patient preference.

The US health care system faces an unsustainable trajectory of high costs and inconsistent outcomes. The fee-for-service payment model has contributed to inefficiency, and new payment methods are a promising approach to improving value. Health reforms are needed to increase patient access, reduce costs, and improve health care quality, and the landmark Medicare Access and CHIP Reauthorization Act presents a roadmap for reform. The product of a collaboration between primary care and cardiology clinicians, this review describes a conceptual approach to delivery and payment reforms that aim to better support primary care-cardiology comanagement of chronic cardiovascular disease (CVD). Few existing alternative payment models specifically address long-term management of CVD. Primary care medical homes and accountable care organizations come closest, but both emphasize primary care, and cardiologists have often not been well engaged. A collaborative care framework should articulate distinct roles and responsibilities for primary care and cardiology in CVD comanagement. Finally, a series of payment models aim to better support clinicians in providing accountable, seamless, and patient-centered cardiac care. Clinical leadership is essential during this time of change in the health care system. Patients often struggle to navigate a fragmented and expensive system, whereas clinicians often practice with incomplete information about tests, treatments, and recommendations by their colleagues. The payment models described in this review offer an opportunity to create more satisfying approaches to patient care while improving value. These models have potential to support more effective coordination and to facilitate broader health care system transformation.

Outbreaks in Health Care Settings.

Outbreaks and pseudo-outbreaks in health care settings can be complex and should be evaluated systematically using epidemiologic tools. Laboratory testing is an important part of an outbreak evaluation. Health care personnel, equipment, supplies, water, ventilation systems, and the hospital environment have been associated with health care outbreaks. Settings including the neonatal intensive care unit, endoscopy, oncology, and transplant units are areas that have specific issues which impact the approach to outbreak investigation and control. Certain organisms have a predilection for health care settings because of the illnesses of patients, the procedures performed, and the care provided. Copyright © 2016 Elsevier Inc.

Mobility decrease is reportedly age-dependent in community dwelling elderly, and a major factor of disability in the geriatric population. The purpose of this study is to examine whether mobility decrease, as assessed using a set of tests, is similarly age-dependent in elderly adults who already have disability. One hundred thirty-five community-dwelling elderly (54 men, 81 women) with disability and 1469 independent community dwellers (1009 men, 460 women) were analyzed. Disability was defined having a certified need for care under the long-term care insurance system in Japan. Lower extremity mobility decrease was quantified using the Locomotive Syndrome Risk Test, which comprises the two-step test, stand-up test, and 25-Question Geriatric Locomotive Function Scale (GLFS-25). Multivariable regression analyses indicated no age-related decrease in the three test scores among elderly with disability, whereas these scores all decreased with age among independent community dwellers. All the test scores decreased as care level increased. Mobility decrease among elderly adults with disability is unrelated to age. However, the severity of care level is associated with mobility decrease.

The field of pediatric palliative care is hindered by the lack of a well-defined, reliable, and valid method for measuring the quality of end-of-life care. The study purpose was to develop and test an instrument to measure mothers' perspectives on the quality of care received before, at the time of, and following a child's death. In Phase 1, key components of quality end-of-life care for children were synthesized through a comprehensive review of research literature. These key components were validated in Phase 2 and then extended through focus groups with bereaved parents. In Phase 3, items were developed to assess structures, processes, and outcomes of quality end-of-life care then tested for content and face validity with health professionals. Cognitive testing was conducted through interviews with bereaved parents. In Phase 4, bereaved mothers were recruited through 10 children's hospitals/hospices in Canada to complete the instrument, and psychometric testing was conducted. Following review of 67 manuscripts and 3 focus groups with 10 parents, 141 items were initially developed. The overall content validity index for these items was 0.84 as rated by 7 health professionals. Based on feedback from health professionals and cognitive testing with 6 parents, a 144-item instrument was finalized for further testing. In Phase 4, 128 mothers completed the instrument, 31 of whom completed it twice. Test-retest reliability, internal consistency, and construct validity were demonstrated for six subscales: Connect With Families, Involve Parents, Share Information With Parents, Share Information Among Health Professionals, Support Parents, and Provide Care at Death. Additional items with content validity were grouped in four domains: Support the Child, Support Siblings, Provide Bereavement Follow-up, and Structures of Care. Forty-eight items were deleted through psychometric testing, leaving a 95-item instrument. There is good initial evidence for the reliability and validity of this new quality of end-of-life care instrument as a mechanism for evaluative feedback to health professionals, health systems, and policy makers to improve children's end-of-life care.

The purpose of this study was to examine the association between utilization of home care services under the national long-term care insurance system and family caregiver distress. A secondary data analysis was conducted in this study using data collected in 2011 and 2012 from the Korean version of International Resident Assessment Instrument (interRAI) Home Care assessment system. The study sample included 228 clients receiving community based home care and their family caregivers in Korea. Descriptive statistics, χ² test, t-test, and Heckman selection model analysis were conducted using SAS 9.3. Presence of family caregiver distress was significantly associated with days of nurse visits (β=-.89, p=<.001) and home helper visits (β=-.53, p=.014). Level of caregiver distress was also significantly associated with days of nurse visits (β=-.66, p=.028). Other factors which were significantly associated with caregiver distress were depression, cognitive function, inadequate pain control, social support for older adult, and caregiver relationship to the older adult. The results of this study show that visiting nurse service and appropriate support programs for Older Adults and family caregivers experiencing caregiver distress should be developed and provided to families based on the health care needs of older adults and their family caregivers for effective and sustainable home care.

Mah, Janet Wt; Tsang, Phoebe

A pilot study to test whether a visual schedule system using picture communication symbols can help children with autism have successful routine dental cleaning visits. 14 boys with autism between three- to eight-years-old presented to the dental clinic for four weekly consecutive dental appointments. Patients were randomly assigned to either the control group who received the tell-show-do method (i.e., standard of care), or the test group who received the tell-show-do method plus the visual schedule system. Patients in the test group completed an average of 1.38 more steps, at 35.52 seconds per step faster, and with 18.7% lower levels of behavioral distress than those in the control group. The use of a visual schedule system, along with repeated weekly visits, showed some promise in helping children with autism successfully complete more steps, progress at a quicker rate, and exhibit lower levels of behavioral distress within a dental appointment, compared to a traditional tell-show-do approach.

As the health care system transitions to a precision medicine approach that tailors clinical care to the genetic profile of the individual patient, there is a potential tension between the clinical uptake of new technologies by providers and the legal system's expectation of the standard of care in applying such technologies. We examine this tension by comparing the type of evidence that physicians and courts are likely to rely on in determining a duty to recommend pharmacogenetic testing of patients prescribed the oral anti-coagulant drug warfarin. There is a large body of inconsistent evidence and factors for and against such testing, but physicians and courts are likely to weigh this evidence differently. The potential implications for medical malpractice risk are evaluated and discussed. © 2016 American Society of Law, Medicine & Ethics.

Consequences of Missed Opportunities for HIV Testing during Pregnancy and Delayed Diagnosis for Mexican Women, Children and Male Partners

PubMed Central

Kendall, Tamil

2014-01-01

Introduction HIV testing during pregnancy permits prevention of vertical (mother-to-child) transmission and provides an opportunity for women living with HIV to access treatment for their own health. In 2001, Mexico’s National HIV Action Plan committed to universal offer of HIV testing to pregnant women, but in 2011, only 45.6% of women who attended antenatal care (ANC) were tested for HIV. The study objective was to document the consequences of missed opportunities for HIV testing and counseling during pregnancy and late HIV diagnosis for Mexican women living with HIV and their families. Methods Semi-structured-interviews with 55 women living with HIV who had had a pregnancy since 2001 were completed between 2009 and 2011. Interviews were analyzed thematically using a priori and inductive codes. Results Consistent with national statistics, less than half of the women living with HIV (42%) were offered HIV testing and counseling during ANC. When not diagnosed during ANC, women had multiple contacts with the health-care system due to their own and other family members’ AIDS-related complications before being diagnosed. Missed opportunities for HIV testing and counseling during antenatal care and health-care providers failure to recognize AIDS-related complications resulted in pediatric HIV infections, AIDS-related deaths of children and male partners, and HIV disease progression among women and other family members. In contrast, HIV diagnosis permitted timely access to interventions to prevent vertical HIV transmission and long-term care and treatment for women living with HIV. Conclusions Omissions of the offer of HIV testing and counseling in ANC and health-care providers’ failure to recognize AIDS-related complications had negative health, economic and emotional consequences. Scaling-up provider-initiated HIV testing and counseling within and beyond antenatal care and pre-service and in-service trainings on HIV and AIDS for health-care providers can hasten timely HIV diagnosis and contribute to improved individual and public health in Mexico.

Multi-spectral imaging systems are often expensive and bulky. An innovative multi-spectral imaging system was fitted onto a mobile colposcope, an imaging system built around a smartphone in order to image the uterine cervix from outside the body. The multi-spectral mobile colposcope (MSMC) acquires images at different wavelengths. This paper presents the clinical testing of MSMC imaging (technical validation of the MSMC system is described elsewhere 1 ). Patients who were referred to colposcopy following abnormal screening test (Pap or HPV DNA test) according to the standard of care were enrolled. Multi-spectral image sets of the cervix were acquired, consisting of images from the various wavelengths. Image acquisition took 1-2 sec. Areas suspected for dysplasia under white light imaging were biopsied, according to the standard of care. Biopsied sites were recorded on a clockface map of the cervix. Following the procedure, MSMC data was processed from the sites of biopsied sites. To date, the initial histopathological results are still outstanding. Qualitatively, structures in the cervical images were sharper at lower wavelengths than higher wavelengths. Patients tolerated imaging well. The result suggests MSMC holds promise for cervical imaging.

Brief alcohol counseling is a top US prevention priority but has not been widely implemented. The lack of an easy performance measure for brief alcohol counseling is one important barrier to implementation. The purpose of this report is to outline important issues related to measuring performance of brief alcohol counseling in health care settings. We review the strengths and limitations of several options for measuring performance of brief alcohol counseling and describe three measures of brief alcohol counseling tested in the Veterans Affairs (VA) Health Care System. We conclude that administrative data are not well-suited to measuring performance of brief alcohol counseling. Patient surveys appear to offer the optimal approach currently available for comparing performance of brief alcohol counseling across health care systems, while more options are available for measuring performance within health care systems. Further research is needed in this important area of quality improvement.

The current and future climates in health care require increased accountability of health care organizations for the quality of the care they provide. Never before in the history of health care in America has this focus on quality been so critical. The imperative to measure nursing's impact without fully developed and tested monitoring systems is a critical issue for nurse executives and managers alike. This article describes a project to measure nursing structure, process, and outcomes in the military health system, the Military Nursing Outcomes Database project. Here we review the effectiveness of this project in monitoring changes over time, in satisfying expectations of nurse leaders in participating hospitals, and evaluate the potential budgetary impacts of such a system. We conclude that the Military Nursing Outcomes Database did meet the needs of a monitoring system that is sensitive to changes over time in outcomes, provides interpretable data for nurse leaders, and could result in cost benefits and patient care improvements in organizations.

The performance of a polymerase chain reaction-based point-of-care assay, the cobas Strep A Nucleic Acid Test for use on the cobas Liat System (cobas Liat Strep A assay), for the detection of group A Streptococcus bacteria was evaluated in primary care settings. Throat swab specimens from 427 patients were tested with the cobas Liat Strep A assay and a rapid antigen detection test (RADT) by existing medical staff at 5 primary care clinics, and results were compared with bacterial culture. The cobas Liat Strep A assay demonstrated equivalent sensitivity (97.7%) and specificity (93.3%) to reference culture with a 15-minute turnaround time. In comparison to RADTs, the cobas Liat Strep A assay showed improved sensitivity (97.7% Liat vs 84.5% RADT). The Clinical Laboratory Improvement Amendments-waived cobas Liat Strep A assay demonstrated the ease of use and improved turnaround time of RADTs along with the sensitivity of culture.

Despite considerable international eHealth impetus, there is no guidance on the development of online clinical care pathways. Advances in diagnostics now enable self-testing with home diagnosis, to which comprehensive online clinical care could be linked, facilitating completely self-directed, remote care. We describe a new framework for developing complex online clinical care pathways and its application to clinical management of people with genital chlamydia infection, the commonest sexually transmitted infection (STI) in England. Using the existing evidence-base, guidelines and examples from contemporary clinical practice, we developed the eClinical Care Pathway Framework, a nine-step iterative process. Step 1: define the aims of the online pathway; Step 2: define the functional units; Step 3: draft the clinical consultation; Step 4: expert review; Step 5: cognitive testing; Step 6: user-centred interface testing; Step 7: specification development; Step 8: software testing, usability testing and further comprehension testing; Step 9: piloting. We then applied the Framework to create a chlamydia online clinical care pathway (Online Chlamydia Pathway). Use of the Framework elucidated content and structure of the care pathway and identified the need for significant changes in sequences of care (Traditional: history, diagnosis, information versus Online: diagnosis, information, history) and prescribing safety assessment. The Framework met the needs of complex STI management and enabled development of a multi-faceted, fully-automated consultation. The Framework provides a comprehensive structure on which complex online care pathways such as those needed for STI management, which involve clinical services, public health surveillance functions and third party (sexual partner) management, can be developed to meet national clinical and public health standards. The Online Chlamydia Pathway's standardised method of collecting data on demographics and sexual behaviour, with potential for interoperability with surveillance systems, could be a powerful tool for public health and clinical management.

Computer-assisted telephone interviewing (CATI) systems used by telephone counselors (TCs) may be efficient mechanisms to counsel patients on cancer and recommended preventive screening tests in order to extend a primary care provider's reach to his/her patients. The implementation process of such a system for promoting colorectal (CRC) cancer screening using a computer-assisted telephone interview (CATI) system is reported in this paper. The process evaluation assessed three components of the intervention: message production, program implementation and audience reception. Of 1181 potentially eligible patients, 1025 (87%) patients were reached by the TCs and 725 of those patients (71%) were eligible to receive counseling. Five hundred eighty-two (80%) patients agreed to counseling. It is feasible to design and use CATI systems for prevention counseling of patients in primary care practices. CATI systems have the potential of being used as a referral service by primary care providers and health care organizations for patient education.

Men who have sex with men (MSM) and transgender women are disproportionately affected by HIV in Guatemala, yet little is known about their experiences with diagnosis, linkage to care, and retention. We conducted qualitative interviews with 26 MSM and transgender women living with HIV in Guatemala City. HIV diagnosis experiences changed over time with increasing asymptomatic testing at non-governmental organizations. Fear of the physical and social impacts of HIV delayed testing, acceptance of diagnosis, and linkage to HIV care. These fears were driven by layered stigma and discrimination due to non-normative gender expressions and/or sexual orientation. Retention-specific determinants included HIV clinic dynamics and limited employment opportunities. There is an urgent need to improve support systems for early testing and linkage to care and to expand employment opportunities. Stigma and discrimination must be addressed at the family, clinic and contextual levels to reduce fear of diagnosis and improve access to care. PMID:27818436

CDC Screening Recommendation for Baby Boomers and Hepatitis C Virus Testing in the US Military Health System.

Chronic hepatitis C virus (HCV) is the most common blood-borne infection in the United States, with an estimated 2.7 to 3.9 million cases as of 2014. In August 2012, the Centers for Disease Control and Prevention (CDC) recommended 1-time HCV testing of all baby boomers. The objectives of this study were to (1) determine the proportion of people screened for HCV in the US Department of Defense Military Health System before and after the CDC screening recommendation for baby boomers and (2) assess whether certain patient or system factors were associated with screening for HCV before and after August 2012. We used a dataset containing 5% of beneficiaries randomly selected from the Military Health System Data Repository medical claims database for the period July 2011 through September 2013. Of 108 223 people eligible for HCV screening during the first period (July 2011 through July 2012), 1812 (1.7%) were screened.

Maintained dedication to primary care has fostered a public health delivery system with exceptional outcomes in Costa Rica. For more than a decade, management commitments have been part of Costa Rican health reform. We assessed the effect of the Costa Rican management commitments on access and quality of care and on compliance with their intended objectives. We constructed seven hypotheses on opinions of primary care providers. Through a mixed qualitative and quantitative approach, we tested these hypotheses and interpreted the research findings. Management commitments consume an excessive proportion of consultation time, inflate recordkeeping, reduce comprehensiveness in primary care consultations, and induce a disproportionate consumption of hospital emergency services. Their formulation relies on norms in need of optimization, their control on unreliable sources. They also affect professionalism. In Costa Rica, management commitments negatively affect access and quality of care and pose a threat to the public service delivery system. The failures of this pay-for-performance-like initiative in an otherwise well-performing health system cast doubts on the appropriateness of pay-for-performance for health systems strengthening in less advanced environments.

Point of Care Testing (POCT) provides the capability for rapid laboratory test results in patient care environments where a traditional clinical laboratory is not available. POCTs have shorter turn-around times (TATs), they may be performed by non-laboratory personnel, and the need for transport time is eliminated. The Food and Drug Administration (FDA) recently granted Clinical Laboratory Improvements Amendment (CLIA) waiver status to the cobas ® Influenza A/B & RSV assay, a rapid, accurate point-of-care test for Influenza and respiratory syncytial virus (RSV) performed on the Liat ® System. The performance characteristics of this test were determined though a multi-site study consisting of different point of care testing environments. Prospectively collected Nasopharyngeal (NP) swabs from 1361 patients seen at 8 primary care clinics and 4 emergency departments (EDs) and 295 retrospectively identified specimens were tested for Influenza A/B and RSV on the cobas ® Liat ® platform. Performance characteristics were determined through comparison to ProFlu+, a laboratory-based PCR test for Influenza A/B and RSV (reference test). Discordant specimens were adjudicated following bi-directional sequencing. The cobas ® Influenza A/B and RSV assay showed sensitivities of 99.6%, 99.3%, and 96.8% for Influenza A, Influenza B, and RSV, respectively as determined from percent positive agreement (PPA) following comparison to the reference test. Sequencing confirmed cobas ® Influenza A/B and RSV results in 49.2% of reference test discordant specimens, while crossing threshold data suggest increased sensitivity compared to the reference test. The cobas ® Influenza A/B and RSV assay was found to be a rapid, sensitive POCT for the detection of these viruses, and provides laboratory-quality PCR-based diagnostic results in point of care settings.

Background Patients undertaking long-term and chronic home hemodialysis (HHD) are subject to feelings of isolation and anxiety due to the absence of physical contact with their health care professionals and lack of feedback in regards to their dialysis treatments. Therefore, it is important for these patients to feel the “presence” of the health care professionals remotely while on hemodialysis at home for better compliance with the dialysis regime and to feel connected with health care professionals. Objective This study presents an HHD system design for hemodialysis patients with features to enhance patient’s perceived “copresence” with their health care professionals. Various mechanisms to enhance this perception were designed and implemented, including digital logbooks, emotion sharing, and feedback tools. The mechanism in our HHD system aims to address the limitations associated with existing self-monitoring tools for HHD patients. Methods A field trial involving 3 nurses and 74 patients was conducted to test the pilot implementation of the copresence design in our HHD system. Mixed method research was conducted to evaluate the system, including surveys, interviews, and analysis of system data. Results Patients created 2757 entries of dialysis cases during the period of study. Altogether there were 492 entries submitted with “Very Happy” as the emotional status, 2167 entries with a “Happy” status, 56 entries with a “Neutral” status, 18 entries with an “Unhappy” status, and 24 entries with a “Very unhappy” status. Patients felt assured to share their emotions with health care professionals. Health care professionals were able to prioritize the review of the entries based on the emotional status and also felt assured to see patients’ change in mood. There were 989 entries sent with short notes. Entries with negative emotions had a higher percentage of supplementary notes entered compared to the entries with positive and neutral emotions. The qualitative data further showed that the HHD system was able to improve patients’ feelings of being connected with their health care professionals and thus enhance their self-care on HHD. The health care professionals felt better assured with patients’ status with the use of the system and reported improved productivity and satisfaction with the copresence enhancement mechanism. The survey on the system usability indicated a high level of satisfaction among patients and nurses. Conclusions The copresence enhancement design complements the conventional use of a digitized HHD logbook and will further benefit the design of future telehealth systems. PMID:28851680

Achieving community-level goals to eliminate the HIV epidemic requires coordinated efforts through community consortia with a common purpose to examine and critique their own HIV testing and treatment (T&T) care system and build effective tools to guide their efforts to improve it. Participatory system dynamics (SD) modeling offers conceptual, methodological, and analytical tools to engage diverse stakeholders in systems conceptualization and visual mapping of dynamics that undermine community-level health outcomes and identify those that can be leveraged for systems improvement. We recruited and engaged a 25-member multi-stakeholder Task Force, whose members provide or utilize HIV-related services, to participate in SD modeling to examine and address problems of their local HIV T&T service system. Findings from the iterative model building sessions indicated Task Force members' increasingly complex understanding of the local HIV care system and demonstrated their improved capacity to visualize and critique multiple models of the HIV T&T service system and identify areas of potential leverage. Findings also showed members' enhanced communication and consensus in seeking deeper systems understanding and options for solutions. We discuss implications of using these visual SD models for subsequent simulation modeling of the T&T system and for other community applications to improve system effectiveness. © Society for Community Research and Action 2017.

Understanding patient willingness to recommend and return: a strategy for prioritizing improvement opportunities.

1999-06-01

Beginning in April 1995, an ongoing, comprehensive measurement system has been developed and refined at BJC Health System, a regional integrated delivery and financing system serving the St Louis metropolitan area, mid-Missouri, and Southern Illinois, to assess patient satisfaction with inpatient treatment, outpatient treatment, outpatient surgery, and emergency care. This system has provided the mechanism for identifying opportunities, setting priorities, and monitoring the impact of improvement initiatives. Satisfaction with key components of the care process among 23,361 patients (7,083 inpatients, 8,885 patients undergoing outpatient tests/procedures, 5,356 patients undergoing outpatient surgery, and 2,037 patients receiving emergency care) at 15 BJC Health System facilities was assessed through weekly surveys administered in April 1995 through December 1996. Structural equation models were developed to identify the key predictors of patient advocation-willingness to return for or recommend care. Across all venues of care the compassion provided to patients had the strongest relationship to patient advocation. Within each venue of care, however, a slightly different set of secondary factors emerged. The resulting models provided important information to help prioritize competing improvement opportunities in BJC Health System. In one hospital, a general medicine unit working for several years with little success to improve its patient satisfaction decided to focus on two primary factors predicting patient advocation: nursing care delivery and compassionate care. Root cause analysis was used to determine why two items-staff willingness to help with questions/concerns and clear explanation about tests and procedures-were rated low. On the basis of feedback from phone interviews with discharged patients, the care delivery process was changed to encourage patients to ask questions. Across the next two quarters, this unit experienced significant improvements in both targeted items. The significance of compassionate care and care delivery again speaks not only to the importance of the technical quality of clinical care but also to the customer-focused way in which this care was provided. After the primary predictors of patient advocation were identified, management was able to strategically focus improvement initiatives to maximize their impact. Across the organization, improvement teams scanned their data to find key factors where performance was lacking. Once these key opportunities were identified, the teams developed potential solutions and launched initiatives to improve their performance. Results suggest that some core issues are of extreme importance to patients regardless of whether they are receiving care in an inpatient, outpatient, or emergency setting. The compassion with which care is provided appears to be the most important factor in influencing patient intentions to recommend/return, regardless of the setting in which care is provided.

Achieving linkage to care and viral suppression in human immunodeficiency virus (HIV)-positive patients improves their well-being and prevents new infections. Current gaps in the HIV care continuum substantially limit such benefits. To evaluate the effectiveness of financial incentives on linkage to care and viral suppression in HIV-positive patients. A large community-based clinical trial that randomized 37 HIV test and 39 HIV care sites in the Bronx, New York, and Washington, DC, to financial incentives or standard of care. Participants at financial incentive test sites who had positive test results for HIV received coupons redeemable for $125 cash-equivalent gift cards upon linkage to care. HIV-positive patients receiving antiretroviral therapy at financial incentive care sites received $70 gift cards quarterly, if virally suppressed. Linkage to care: proportion of HIV-positive persons at the test site who linked to care within 3 months, as indicated by CD4+ and/or viral load test results done at a care site. Viral suppression: proportion of established patients at HIV care sites with suppressed viral load (<400 copies/mL), assessed at each calendar quarter. Outcomes assessed through laboratory test results reported to the National HIV Surveillance System. A total of 1061 coupons were dispensed for linkage to care at 18 financial incentive test sites and 39 359 gift cards were dispensed to 9641 HIV-positive patients eligible for gift cards at 17 financial incentive care sites. Financial incentives did not increase linkage to care (adjusted odds ratio, 1.10; 95% CI, 0.73-1.67; P = .65). However, financial incentives significantly increased viral suppression. The overall proportion of patients with viral suppression was 3.8% higher (95% CI, 0.7%-6.8%; P = .01) at financial incentive sites compared with standard of care sites. Among patients not previously consistently virally suppressed, the proportion virally suppressed was 4.9% higher (95% CI, 1.4%-8.5%; P = .007) at financial incentive sites. In addition, continuity in care was 8.7% higher (95% CI, 4.2%-13.2%; P < .001) at financial incentive sites. Financial incentives, as used in this study (HPTN 065), significantly increased viral suppression and regular clinic attendance among HIV-positive patients in care. No effect was noted on linkage to care. Financial incentives offer promise for improving adherence to treatment and viral suppression among HIV-positive patients. clinicaltrials.gov Identifier: NCT01152918.

This paper reports the use and non-use of health care facilities in the Hill villages in central Nepal. The health behaviour model (HBM) is applied to test the significance of socioeconomic variables on the use of the modern health care system. The study finds that all three characteristics of the HBM model, predisposing, enabling and need, are significantly related to use and non-use of the modern health care system. The analysis shows that number of living children, respondent's education, nearness to the road and service centre, value of land, knowledge about health workers and experience of child loss are some of the variables that are positively and significantly related to the use of modern health care. Age of the respondents and household size were found to be negatively associated with health-care use. Contrary to expectation, caste is unimportant. Making use of the qualitative data, this paper argues that the health care system is unnecessarily bureaucratic and patriarchal, which favours the socio-economically well-off.

Cataracts are eye diseases characterized by cloudy or opacity of the lens of the eye by changing the colour of black into grey-white which slowly continues to grow and develop without feeling pain and pain that can cause blindness in human vision. Therefore, researchers make an expert system of cataract eye disease diagnosis by using Fuzzy Mamdani and how to care. The fuzzy method can convert the crisp value to linguistic value by fuzzification and includes in the rule. So this system produces an application program that can help the public in knowing cataract eye disease and how to care based on the symptoms suffered. From the results of the design implementation and testing of expert system applications to diagnose eye disease cataracts, it can be concluded that from a trial of 50 cases of data, obtained test results accuracy between system predictions with expert predictions obtained a value of 78% truth.

Systems modeling and simulation applications for critical care medicine

PubMed Central

2012-01-01

Critical care delivery is a complex, expensive, error prone, medical specialty and remains the focal point of major improvement efforts in healthcare delivery. Various modeling and simulation techniques offer unique opportunities to better understand the interactions between clinical physiology and care delivery. The novel insights gained from the systems perspective can then be used to develop and test new treatment strategies and make critical care delivery more efficient and effective. However, modeling and simulation applications in critical care remain underutilized. This article provides an overview of major computer-based simulation techniques as applied to critical care medicine. We provide three application examples of different simulation techniques, including a) pathophysiological model of acute lung injury, b) process modeling of critical care delivery, and c) an agent-based model to study interaction between pathophysiology and healthcare delivery. Finally, we identify certain challenges to, and opportunities for, future research in the area. PMID:22703718

Care for seniors is complex because patients often have more than one disease, one medication, and one physician. It is a key challenge for primary care physicians to structure the various aspects of each patient's care, to integrate each patient's preferences, and to maintain a long-term overview. This article describes the design for the development and feasibility testing of the clinical decision support system (CDSS) eCare*Seniors© which is electronic health record (EHR)-based allowing for a long-term, comprehensive, evidence-based, and patient preference-oriented management of multimorbid seniors. This mixed-methods study is designed in three steps. First, focus groups and practice observations will be conducted to develop criteria for software design from a physicians' and practice assistants' perspective. Second, based on these criteria, a CDSS prototype will be developed. Third, the prototype's feasibility will be tested by five primary care practices in the care of 30 multimorbid seniors. Primary outcome is the usability of the software measured by the validated system usability scale (SUS) after 3 months. Secondary outcomes are the (a) willingness to routinely use the CDSS, (b) degree of utilization of the CDSS, (c) acceptance of the CDSS, (d) willingness of the physicians to purchase the CDSS, and (e) willingness of the practice assistants to use the CDSS in the long term. These outcomes will be measured using semi-structured interviews and software usage data. If the SUS score reaches ≥70 %, feasibility testing will be judged successful. Otherwise, the CDSS prototype will be refined according to the users' needs and retested by the physicians and practice assistants until it is fully adapted to their requirements and reaches a usability score ≥70 %. The study will support the development of a CDSS which is primary care-defined, user-friendly, easy-to-comprehend, workflow-oriented, and comprehensive. The software will assist physicians and practices in their long-term, individualized care for multimorbid seniors. German Clinical Trials Register, DRKS00008777.

Laboratory information systems (LIS) are critical components of the operation of clinical laboratories. However, the functionalities of LIS have lagged significantly behind the capacities of current hardware and software technologies, while the complexity of the information produced by clinical laboratories has been increasing over time and will soon undergo rapid expansion with the use of new, high-throughput and high-dimensionality laboratory tests. In the broadest sense, LIS are essential to manage the flow of information between health care providers, patients, and laboratories and should be designed to optimize not only laboratory operations but also personalized clinical care. To list suggestions for designing LIS with the goal of optimizing the operation of clinical laboratories while improving clinical care by intelligent management of laboratory information.

2013-01-01

Objective A bundled hospital payment system that encompasses both acute and post-acute care has been proposed as a means of creating financial incentives in the Medicare fee-for-service system to foster care coordination and to improve the current disorganized system of post care. The objective of this study was to evaluate the statistical stability of alternative designs of a hospital payment system that includes post-acute care services to determine the feasibility of using a combined hospital and post-acute care bundle as a unit of payment. Methods The Medicare Severity-Diagnosis Related Groups (MS-DRGs) were subdivided into clinical subclasses that measured a patient's chronic illness burden to test whether a patient's chronic illness burden had a substantial impact on post-acute care expenditures. Using Medicare data the statistical performance of the MS-DRGs with and without the chronic illness subclasses was evaluated across a wide range of post-acute care windows and combinations of post-acute care service bundles using both submitted charges and Medicare payments. Results The statistical performance of the MS-DRGs as measured by R2 was consistently better when the chronic illness subclasses are included indicating that MS-DRGs by themselves are an inadequate unit of payment for post-acute care payment bundles. In general, R2 values increased as the post-acute care window length increased and decreased as more services were added to the post-acute care bundle. Discussion The study results suggest that it is feasible to develop a payment system that incorporates significant post-acute care services into the MS-DRG inpatient payment bundle. This expansion of the basic DRG payment approach can provide a strong financial incentive for providers to better coordinate care potentially leading to improved efficiency and outcome quality.

Integrating Social impacts on Health and Health-Care Systems in Systemic Seismic Vulnerability Analysis

Kunz-Plapp, T.; Khazai, B.; Daniell, J. E.

2012-04-01

This paper presents a new method for modeling health impacts caused by earthquake damage which allows for integrating key social impacts on individual health and health-care systems and for implementing these impacts in quantitative systemic seismic vulnerability analysis. In current earthquake casualty estimation models, demand on health-care systems is estimated by quantifying the number of fatalities and severity of injuries based on empirical data correlating building damage with casualties. The expected number of injured people (sorted by priorities of emergency treatment) is combined together with post-earthquake reduction of functionality of health-care facilities such as hospitals to estimate the impact on healthcare systems. The aim here is to extend these models by developing a combined engineering and social science approach. Although social vulnerability is recognized as a key component for the consequences of disasters, social vulnerability as such, is seldom linked to common formal and quantitative seismic loss estimates of injured people which provide direct impact on emergency health care services. Yet, there is a consensus that factors which affect vulnerability and post-earthquake health of at-risk populations include demographic characteristics such as age, education, occupation and employment and that these factors can aggravate health impacts further. Similarly, there are different social influences on the performance of health care systems after an earthquake both on an individual as well as on an institutional level. To link social impacts of health and health-care services to a systemic seismic vulnerability analysis, a conceptual model of social impacts of earthquakes on health and the health care systems has been developed. We identified and tested appropriate social indicators for individual health impacts and for health care impacts based on literature research, using available European statistical data. The results will be used to develop a socio-physical model of systemic seismic vulnerability that enhances the further understanding of societal seismic risk by taking into account social vulnerability impacts for health and health-care system, shelter, and transportation.

In this paper we present a portable blood analysis system based on a disposable cartridge and hand-held reader. The platform can perform all the sample preparation, detection and waste collection required to complete a clinical test. In order to demonstrate the utility of this approach a CD4 T cell enumeration was carried out. A handheld, point-of-care CD4 T cell system was developed based on this system. In particular we will describe a pneumatic, active pumping method to control the on-chip fluidic actuation. Reagents for the CD4 T cell counting assay were dried on a reagent plug to eliminate the need for cold chain storage when used in the field. A micromixer based on the active fluidic actuation was designed to complete sample staining with fluorescent dyes that was dried on the reagent plugs. A novel image detection and analysis algorithm was developed to detect and track the flight of target particles and cells during each analysis. The handheld, point-of-care CD4 testing system was benchmarked against clinical cytometer. The experimental results demonstrated experimental results were closely matched with the flow cytometry. The same platform can be further expanded into a bead-array detection system where other types of biomolecules such as proteins can be detected using the same detection system.

Patient-Centered Appointment Scheduling Using Agent-Based Simulation

Enhanced access and continuity are key components of patient-centered care. Existing studies show that several interventions such as providing same day appointments, walk-in services, after-hours care, and group appointments, have been used to redesign the healthcare systems for improved access to primary care. However, an intervention focusing on a single component of care delivery (i.e. improving access to acute care) might have a negative impact other components of the system (i.e. reduced continuity of care for chronic patients). Therefore, primary care clinics should consider implementing multiple interventions tailored for their patient population needs. We collected rapid ethnography and observations to better understand clinic workflow and key constraints. We then developed an agent-based simulation model that includes all access modalities (appointments, walk-ins, and after-hours access), incorporate resources and key constraints and determine the best appointment scheduling method that improves access and continuity of care. This paper demonstrates the value of simulation models to test a variety of alternative strategies to improve access to care through scheduling. PMID:25954423

Older adults are at risk for inadequate emergency department (ED) pain care. Unrelieved acute pain is associated with poor outcomes. Clinical decision support systems (CDSS) hold promise to improve patient care, but CDSS quality varies widely, particularly when usability evaluation is not employed. To conduct an iterative usability and redesign process of a novel geriatric abdominal pain care CDSS. We hypothesized this process would result in the creation of more usable and favorable pain care interventions. Thirteen emergency physicians familiar with the Electronic Health Record (EHR) in use at the study site were recruited. Over a 10-week period, 17 1-hour usability test sessions were conducted across 3 rounds of testing. Participants were given 3 patient scenarios and provided simulated clinical care using the EHR, while interacting with the CDSS interventions. Quantitative System Usability Scores (SUS), favorability scores and qualitative narrative feedback were collected for each session. Using a multi-step review process by an interdisciplinary team, positive and negative usability issues in effectiveness, efficiency, and satisfaction were considered, prioritized and incorporated in the iterative redesign process of the CDSS. Video analysis was used to determine the appropriateness of the CDS appearances during simulated clinical care. Over the 3 rounds of usability evaluations and subsequent redesign processes, mean SUS progressively improved from 74.8 to 81.2 to 88.9; mean favorability scores improved from 3.23 to 4.29 (1 worst, 5 best). Video analysis revealed that, in the course of the iterative redesign processes, rates of physicians' acknowledgment of CDS interventions increased, however most rates of desired actions by physicians (such as more frequent pain score updates) decreased. The iterative usability redesign process was instrumental in improving the usability of the CDSS; if implemented in practice, it could improve geriatric pain care. The usability evaluation process led to improved acknowledgement and favorability. Incorporating usability testing when designing CDSS interventions for studies may be effective to enhance clinician use.

Due to the nature of information generation in health care, clinical documents contain duplicate and sometimes conflicting information. Recent implementation of Health Information Exchange (HIE) mechanisms in which clinical summary documents are exchanged among disparate health care organizations can proliferate duplicate and conflicting information. To reduce information overload, a system to automatically consolidate information across multiple clinical summary documents was developed for an HIE network. The system receives any number of Continuity of Care Documents (CCDs) and outputs a single, consolidated record. To test the system, a randomly sampled corpus of 522 CCDs representing 50 unique patients was extracted from a large HIE network. The automated methods were compared to manual consolidation of information for three key sections of the CCD: problems, allergies, and medications. Manual consolidation of 11,631 entries was completed in approximately 150h. The same data were automatically consolidated in 3.3min. The system successfully consolidated 99.1% of problems, 87.0% of allergies, and 91.7% of medications. Almost all of the inaccuracies were caused by issues involving the use of standardized terminologies within the documents to represent individual information entries. This study represents a novel, tested tool for de-duplication and consolidation of CDA documents, which is a major step toward improving information access and the interoperability among information systems. While more work is necessary, automated systems like the one evaluated in this study will be necessary to meet the informatics needs of providers and health systems in the future.

This study examined the usability of six differing electronic nursing record (ENR) systems on the efficiency, proficiency and available functions for documenting nursing care and subsequently compared the results to nurses' perceived satisfaction from a previous study. The six hospitals had different ENR systems, all with narrative nursing notes in use for more than three years. Stratified by type of nursing unit, 54 staff nurses were digitally recorded during on-site usability testing by employing validated patient care scenarios and think-aloud protocols. The time to complete specific tasks was also measured. Qualitative performance data were converted into scores on efficiency (relevancy), proficiency (accuracy), and a competency index using scoring schemes described by McGuire and Babbott. Six nurse managers and the researchers completed assessments of available ENR functions and examined computerized nursing process components including the linkages among them. For the usability test, participants' mean efficiency score was 94.2% (95% CI, 91.4-96.9%). The mean proficiency was 60.6% (95% CI, 54.3-66.8%), and the mean competency index was 59.5% (95% CI, 52.9-66.0). Efficiency scores were significantly different across ENRs as was the time to complete tasks, ranging from 226.3 to 457.2s (χ(2)=12.3, P=0.031; χ(2)=11.2, P=0.048). No significant differences were seen for proficiency scores. The coverage of the various ENRs' nursing process ranged from 67% to 100%, but only two systems had complete integration of nursing components. Two systems with high efficiency and proficiency scores had much lower usability test scores and perceived user satisfaction along with more complex navigation patterns. In terms of system usability and functions, different levels of sophistication of and interaction performance with ENR systems exist in practice. This suggests that ENRs may have variable impacts on clinical outcomes and care quality. Future studies are needed to explore ENR impact on nursing care quality, efficiency, and safety.

The scale-up of effective HIV viral load (VL) testing is an urgent public health priority. Implementation of testing is supported by the availability of accurate, nucleic acid based laboratory and point-of-care (POC) VL technologies and strong WHO guidance recommending routine testing to identify treatment failure. However, test implementation faces challenges related to the developing health systems in many low-resource countries. The purpose of this commentary is to review the challenges and solutions from the large-scale implementation of other diagnostic tests, namely nucleic-acid based early infant HIV diagnosis (EID) and CD4 testing, and identify key lessons to inform the scale-up of VL. Experience with EID and CD4 testing provides many key lessons to inform VL implementation and may enable more effective and rapid scale-up. The primary lessons from earlier implementation efforts are to strengthen linkage to clinical care after testing, and to improve the efficiency of testing. Opportunities to improve linkage include data systems to support the follow-up of patients through the cascade of care and test delivery, rapid sample referral networks, and POC tests. Opportunities to increase testing efficiency include improvements to procurement and supply chain practices, well connected tiered laboratory networks with rational deployment of test capacity across different levels of health services, routine resource mapping and mobilization to ensure adequate resources for testing programs, and improved operational and quality management of testing services. If applied to VL testing programs, these approaches could help improve the impact of VL on ART failure management and patient outcomes, reduce overall costs and help ensure the sustainable access to reduced pricing for test commodities, as well as improve supportive health systems such as efficient, and more rigorous quality assurance. These lessons draw from traditional laboratory practices as well as fields such as logistics, operations management and business. The lessons and innovations from large-scale EID and CD4 programs described here can be adapted to inform more effective scale-up approaches for VL. They demonstrate that an integrated approach to health system strengthening focusing on key levers for test access such as data systems, supply efficiencies and network management. They also highlight the challenges with implementation and the need for more innovative approaches and effective partnerships to achieve equitable and cost-effective test access. © 2017 The Authors.

In the context of public health policies, healthcare network is a strategy that aims to promote people's equitable access to services and to reduce fragmentation. The aim of this study was to evaluate the degree of development of components in a healthcare network for hypertension. This was an ex-ante, cross-sectional evaluative study focused on the implementation of a healthcare network for persons with chronic diseases, applying a questionnaire to 17 health administrators from the municipalities (counties) comprising the largest health district in Mato Grosso do Sul State, Brazil. The questionnaire consisted of 65 questions covering the five components: Primary Health Care; Specialized Care; Support Systems; Logistics Systems; and Governance. The study conducted descriptive statistical tests and the classification of services provided in each component using the Friedman test, followed by the Student-Newman-Keuls post hoc test, with significance set at 5%. The results were distributed in quartiles and presented in boxplot graphs. Correlations were established between the dimensions. According to the findings, the components are in an intermediate degree of implementation, with low development of the items needed for establishing networks. Primary Health Care does not coordinate the care, and the Specialized Care and Governance components showed the worst results. The findings indicate predominance of installed services that still fall short of the necessary practices for establishing healthcare networks, which can compromise their implementation.

To report additional mediation findings from a descriptive cross sectional study to examine if nurses' perceptions of the impact of healthcare information technology on their practice mediates the relationship between electronic nursing care reminder use and missed nursing care. The study used a descriptive design. The sample (N = 165) was composed of registered nurses working on acute care hospital units. The sample was obtained from a large teaching hospital in Southeast Michigan in the fall of 2012. All eligible nursing units (n = 19) were included. The MISSCARE Survey, Nursing Care Reminders Usage Survey, and the Impact of Healthcare Information Technology Scale were used to collect data to test for mediation. Mediation was tested using the method described by Baron and Kenny. Multiple regression equations were used to analyze the data to determine if mediation occurred between the variables. Missed nursing care, the outcome variable, was regressed on the predictor variable, reminder usage, and the mediator variable impact of technology on nursing practice. The impact of healthcare information technology (IHIT) on nursing practice negatively affected missed nursing care (t = -4.12, p < .001), explaining 9.8% of variance in missed nursing care. With IHIT present, the predictor (reminder usage) was no longer significant (t = -.70, p = .48). Thus, the reduced direct association between reminder usage and missed nursing care when IHIT was in the model supported the hypothesis that IHIT was at least one of the mediators in the relationship between reminder usage and missed nursing care. The perceptions of the impact of healthcare information technology mediates the relationship between nursing care reminder use and missed nursing care. The findings are beneficial to the advancement of healthcare technology in that designers of healthcare information technology systems need to keep in mind that perceptions regarding impacts of the technology will influence usage. Many times, information technology systems are not designed to match the workflow of nurses. Systems built with redundant or impertinent reminders may be ignored. System designers must study which reminders nurses find most useful and which reminders result in the best quality outcomes. © 2015 Sigma Theta Tau International.

Rapid diagnostic Tests (RDTs) for malaria enable diagnostic testing at primary care facilities in resource-limited settings, where weak infrastructure limits the use of microscopy. In 2010, Ghana adopted a test-before-treat guideline for malaria, with RDT use promoted to facilitate diagnosis. Yet healthcare practitioners still treat febrile patients without testing, or despite negative malaria test results. Few studies have explored RDT implementation beyond the notions of provider or patient acceptability. The aim of this study was to identify the factors directly influencing malaria RDT implementation at primary care facilities in a Ghanaian district. Qualitative interviews, focus groups and direct observations were conducted with 50 providers at six purposively selected primary care facilities in the Atwima-Nwabiagya district. Data were analysed thematically. RDT implementation was hampered by: (1) healthcare delivery constraints (weak supply chain, limited quality assurance and control, inadequate guideline emphasis, staffing limitations); (2) provider perceptions (entrenched case-management paradigms, limited preparedness for change); (3) social dynamics of care delivery (expected norms of provider-patient interaction, test affordability); and (4) limited provider engagement in policy processes leading to fragmented implementation of health sector reform. Limited health system capacity, socio-economic, political, and historical factors hampered malaria RDT implementation at primary care facilities in the study district. For effective RDT implementation providers must be: (1) adequately enabled through efficient allocation and management of essential healthcare commodities; (2) appropriately empowered with the requisite knowledge and skill through ongoing, effective professional development; and (3) actively engaged in policy dialogue to demystify socio-political misconceptions that hinder health sector reform policies from improving care delivery. Clear, consistent guideline emphasis, with complementary action to address deep-rooted provider concerns will build their confidence in, and promote uptake of recommended policies, practices, and technology for diagnosing malaria.

Computerised Order Entry Systems and Pathology Services - A Synthesis of the Evidence

Georgiou, Andrew; Westbrook, Johanna I

2006-01-01

Computerised Physician Order Entry (CPOE) systems have been promoted in Australia and internationally for their potential to improve the quality of care. The existing research of the effect of CPOE on pathology laboratories has been variable, pointing to the potential to increase efficiency and effectiveness and contribute to enhancing the quality of patient care on the one hand, while leading to significant disruptions in work organisation with a negative impact on departmental relations on the other hand. In this paper we provide an overview of the research evidence about the impact of CPOE on four areas associated with pathology services; a) efficiency of the ordering process, e.g. test turnaround times, b) effectiveness as measured by test ordering volumes and test order appropriateness, c) quality of care, particularly its effects on patient care and d) work organisation patterns, which can be severely disrupted by CPOE. We discuss the possible ramifications of CPOE and offer three broad, but important recommendations for pathology laboratories, based on our own research experience investigating CPOE implementations over three years. Firstly, pathology laboratories need to be active participants in planning the implementation of CPOE. Secondly, the importance of building a firm organisational foundation for the introduction of the new system that includes openness and responsiveness to feedback. And thirdly, the implementation process needs to be underpinned by a strong commitment to a multi-method evaluation at every stage of the process to be able to measure the impact of the system on work practices and outcomes.

The study's objective was to assess the effects of automated telephone outreach with speech recognition (ATO-SR) on diabetes-related testing. We identified 1,200 health plan members who were overdue for diabetes-related testing and randomly allocated 600 to ATO-SR and 600 to usual care (no intervention). The intervention included three interactive calls encouraging recommended testing. The primary outcome was retinopathy testing, since this was the health plan's principal goal. Tests for glycemia, hyperlipidemia, and nephropathy were secondary outcomes. In total, 232 participants (39%) verbally responded to the calls. There was no difference between the intervention and the usual care groups in the primary outcome (adjusted hazard ratio 0.93 [95% CI 0.71-1.22]) and no effect of the intervention on any of the secondary outcomes. Fewer than 40% of the patients randomized to ATO-SR interacted verbally with the system. The intervention had no effect on the study's outcomes.

Traditional and emerging forms of dental practice. Cost, accessibility, and quality factors.

The traditional and predominant manner of delivering dental care is through a fee-for-service, private practice system. A number of alternative dental care delivery systems have emerged and are being tested, and others are just emerging. These systems include department store practices, hospital dental services, health maintenance organizations, the independent practice of dental hygiene, and denturism. Although it is too soon to draw final conclusions about the efficacy and effectiveness of these systems, we examine them for their potential to compete with and change the way dental care is currently delivered. Using the parameters of cost, accessibility, and quality, we compare these systems to traditional dental practice. Some of these emerging forms clearly have the potential to complete favorably with traditional practice. Other seem less likely to alter the existing system substantially. The system which can best control costs, increase accessibility, and enhance quality will gain the competitive edge. PMID:7091453

Medicare no longer reimburses acute care hospitals for the costs of additional care required due to hospital-acquired injuries. Consequently, this study explored the effective computerized systems to inform practice for better interventions to reduce fall risk. It provided a correlation between type of computerized system and hospital-acquired injurious fall rates at acute care hospitals in California, Florida, and New York. It used multiple publicly available data sets, with the hospital as the unit of analysis. Descriptive and Pearson correlation analyses were used. The analysis included 462 hospitals. Significant correlations could be categorized into two groups: (1) meaningful computerized systems that were associated with lower injurious fall rates: the decision support systems for drug allergy alerts, drug-drug interaction alerts, and drug-laboratory interaction alerts; and (2) computerized systems that were associated with higher injurious fall rates: the decision support system for drug-drug interaction alerts and the computerized provider order entry system for radiology tests. Future research may include additional states, multiple years of data, and patient-level data to validate this study's findings. This effort may further inform policy makers and the public about effective clinical computerized systems provided to clinicians to improve their practice decisions and care outcomes.

Principles of Point of Care Culture, the Spatial Care Path™, and Enabling Community and Global Resilience: Enabling Community and Global Resilience.

PubMed

Gerald, J Kost; William, J Ferguson; Laurie, E Kost

2014-09-01

This article a) defines point of care (POC) culture; b) presents seven underlying fundamental principles; c) describes the importance of needs assessment; d) introduces a new innovation, the spatial care path™; and e) illustrates how POC testing that properly fulfills needs and spatial care paths™ enable community and global resilience. Often, POC testing supplants the conventional clinical laboratory, which may be too distant, prohibitively expensive, or simply not available in limited-resource settings. New POC technologies "fit" future medical problem solving. Screening and testing directly in the home or primary care facilitate rapid diagnosis, monitoring, and treatment. In contrast to the past where attention has been placed on emergency departments, hospitals, and referral centers, the spatial care path™ starts with the patient and guides him or her through an efficient strategy of care in small-world networks (SWNs) defined by local geography and topology, long-standing customs, public health jurisdictions, and geographic information systems (GIS). POC testing needs in limited-resource settings are striking. Fulfillment is best guided by thorough understanding of POC culture. Quick feedback and fast decision-making by patients and physicians alike yield significant value that motivates changes in patient lifestyles and physician interactions. Culturally sensitive technology assimilation addresses leadership challenges in nations adapting to increasing populations of young and old, despite scarcity of resources. The spatial care path™ facilitates an essential balance of prevention and intervention in public health and shifts future focus to the patient, empowerment, and primary care within the context of POC culture.

Introduction The need for efficient retention in HIV care is more evident than ever because of the expansion of earlier ART initiation and the shift towards ‘Test and Treat’. This study assesses factors affecting participation in the HIV care cascade among people living with HIV (PLHIV) in the Asia-Pacific Region. Methods A total of 7843 PLHIV aged 18–50 years were recruited using targeted and venue-based sampling between October 1, 2012, and May 31, 2013, across 59 sites in 7 countries (Bangladesh, Indonesia, Lao People's Democratic Republic (Lao PDR), Nepal, Pakistan, Philippines and Vietnam). Statistically significant associations between demographic and health system determinants, and various steps in the HIV care cascade were computed using a generalized structural equation model. Results A high proportion of PLHIV (40–51%) presented late for HIV care and delayed linkage to care in all seven countries. However, once PLHIV enrolled in care, retention in the various steps of the care cascade including adherence to antiretroviral treatment (ART) was satisfactory. The proportion still engaged in HIV care at 36 months post HIV diagnosis, varied from 78% in Nepal to >90% in Lao PDR. Similarly, the proportion of ART initiation who also were adherent to ART ranged from 91% in Bangladesh to >95% in Philippines/ Vietnam and from 70% in Lao PDR to 89% in the Philippines respectively. The following factors enhanced the likelihood of ART initiation and high adherence to HIV care and ART: good client-provider communication, high HIV treatment literacy, a referral from a health worker and TB/HIV co-infection. The following barriers were identified: young age, sex work, imprisonment, transgender identity, illiteracy, rural residence, alcohol/ injecting drug use, perceived poor health status, lack of health insurance, fear of confidentiality breach, self-referral for HIV testing, and public hospital as the place of HIV diagnosis. Conclusions HIV programme planners should ensure easy access to HIV testing and earlier linkage to HIV care among PLHIV. In addition, multiple socio-economic and health systems barriers need to be addressed along the HIV care cascade to reach the UNAIDS 90-90-90 target in the Asia-Pacific region. PMID:28459881

Strong laboratory services and systems are critical for delivering timely and quality health services that are vital to reduce patient attrition in the HIV treatment and prevention cascade. However, challenges exist in ensuring effective laboratory health systems strengthening and linkages. In particular, linkages and referrals between laboratory testing and other services need to be considered in the context of an integrated health system that includes prevention, treatment, and strategic information. Key components of laboratory health systems that are essential for effective linkages include an adequate workforce, appropriate point-of-care (POC) technology, available financing, supply chain management systems, and quality systems improvement, including accreditation. In this review, we highlight weaknesses of and gaps between laboratory testing and other program services. We propose a model for strengthening these systems to ensure effective linkages of laboratory services for improved access and retention in care of HIV/AIDS patients, particularly in low- and middle-income countries.

Testing the usability of two automated home-based patient-management systems.

To explore to what extent observation and semistructured in-depth interviews provide effective tools for usability testing of two automated home-based systems aimed at monitoring patients' health status at home and improving self-care. Telephone-Linked Care for Diet Adherence in Dyslipidemia (TLC-DietAid) used computer telephony to interact with users and Home Asthma Telemonitoring System (HAT System) used a combination of Personal Digital Assistant (palmtops) and the Internet for similar purposes. Both systems were evaluated in two separate pilot studies. Our pilot studies uncovered "medium-specific" and "content-specific" issues that addressed either the process of the interaction or its content. The results demonstrated that patient-users tended to evaluate each system on the basis of how it fit into everyday life and corresponded to personal preferences. The methodology also allowed the system designers to understand users' concerns and the context of adoption in order to introduce necessary changes to the design to address such concerns.

Point-of-Care Hemoglobin A1c Testing: An Evidence-Based Analysis

PubMed Central

2014-01-01

Background The increasing prevalence of diabetes in Ontario means that there will be growing demand for hemoglobin A1c (HbA1c) testing to monitor glycemic control for the management of this chronic disease. Testing HbA1c where patients receive their diabetes care may improve system efficiency if the results from point-of-care HbA1c testing are comparable to those from laboratory HbA1c measurements. Objectives To review the correlation between point-of-care HbA1c testing and laboratory HbA1c measurement in patients with diabetes in clinical settings. Data Sources The literature search included studies published between January 2003 and June 2013. Search terms included glycohemoglobin, hemoglobin A1c, point of care, and diabetes. Review Methods Studies were included if participants had diabetes; if they compared point-of-care HbA1c devices (licensed by Health Canada and available in Canada) with laboratory HbA1c measurement (reference method); if they performed point-of-care HbA1c testing using capillary blood samples (finger pricks) and laboratory HbA1c measurement using venous blood samples within 7 days; and if they reported a correlation coefficient between point-of-care HbA1c and laboratory HbA1c results. Results Three point-of-care HbA1c devices were reviewed in this analysis: Bayer's A1cNow+, Bio-Rad's In2it, and Siemens’ DCA Vantage. Five observational studies met the inclusion criteria. The pooled results showed a positive correlation between point-of-care HbA1c testing and laboratory HbA1c measurement (correlation coefficient, 0.967; 95% confidence interval, 0.960–0.973). Limitations Outcomes were limited to the correlation coefficient, as this was a commonly reported measure of analytical performance in the literature. Results should be interpreted with caution due to risk of bias related to selection of participants, reference standards, and the multiple steps involved in POC HbA1c testing. Conclusions Moderate quality evidence showed a positive correlation between point-of-care HbA1c testing and laboratory HbA1c measurement. Five observational studies compared 3 point-of-care HbA1c devices with laboratory HbA1c assays, and all reported strong correlation between the 2 tests. PMID:26316922

HIV testing and counseling is a critical component of HIV prevention efforts and core element of current “treatment as prevention” strategies. Mobility, low education and income, and limited access to health care put Latino migrants at higher risk for HIV and represent barriers for adequate levels of HIV testing in this population. We examined correlates of, and missed opportunities to increase, HIV testing for circular Mexican migrants in the U.S. We used data from a probability-based survey of returning Mexican migrants (N=1161) conducted in the border city of Tijuana, Mexico. We estimated last 12-months rates of HIV testing and the percentage of migrants who received other health care services or were detained in an immigration center, jail, or prison for 30 or more days in the U.S., but were not tested for HIV. Twenty-two percent of migrants received HIV testing in the last 12 months. In general, utilization of other health care services or detention for 30 or more days in the U.S. was a significant predictor of last 12-months HIV testing. Despite this association, we found evidence of missed opportunities to promote testing in healthcare and/or correctional or immigration detention centers. About 27.6% of migrants received other health care and/or were detained at least 30 days but not tested for HIV. Health care systems, jails and detention centers play an important role in increasing access to HIV testing among circular migrants, but there is room for improvement. Policies to offer opt-out, confidential HIV testing and counseling to Mexican migrants in these settings on a routine and ethical manner need to be designed and pilot tested. These policies could increase knowledge of HIV status, facilitate engagement in HIV treatment among a highly mobile population, and contribute to decrease incidence of HIV in the host and receiving communities.

Point-of-care (POC) diagnostic devices are integral in the health care system and particularly for the diagnosis and monitoring of diseases. POC testing has a variety of advantages including the ability to provide rapid and accurate results, ease of use, low cost, and little need for specialized equipment. One of the goals of POC testing is the development of a chip-based, miniaturized, portable, and self-containing system that allows for the assay of different analytes in complex samples. To achieve these goals, many researchers have focused on paper-based and printed electrode technologies as the material for fabricating POC diagnostic systems. These technologies are affordable, sensitive, user-friendly, rapid, and scalable for manufacturing. Moreover, the combination such devices with nanomaterials provide a path for the development of highly sensitive and selective biosensors for future generation POC tools. This review article discusses present technologies in on-site or at home POC diagnostic assays implemented in paper-based microfluidic and screen printing devices over the past decade as well as in the near future. In addition, recent advances in the application of nanomaterials such as gold nanoparticles, carbon nanotubes (CNTs), magnetic nanoparticles, and graphene in POC devices will be reviewed. The factors that limit POC testing to become real world products and future directions are also identified. Copyright © 2016 Elsevier B.V. All rights reserved.

Wallin, Mats K E B; Wajntraub, Samson

2004-03-01

In today's intensive care and surgery, a great number of cables are attached to patients. These cables can make the care and nursing of the patient difficult. Replacing them with wireless communications technology would facilitate patient care. Bluetooth is a modern radio technology developed specifically to replace cables between different pieces of communications equipment. In this study we sought to determine whether Bluetooth is a suitable replacement for cables in intensive care and during surgery with respect to electromagnetic compatibility. The following questions were addressed: Does Bluetooth interfere with medical equipment? And does the medical equipment decrease the quality of the Bluetooth communication? A Bluetooth link, simulating a patient monitoring system, was constructed with two laptops. The prototype was then used in laboratory and clinical tests according to American standards at the Karolinska Hospital in Stockholm. The tests, which included 44 different pieces of medical equipment, indicated that Bluetooth does not cause any interference. The tests also showed that the hospital environment does not affect the Bluetooth communication negatively. Bluetooth, a new radio technology transmitting at 2.4 GHz, was tested in a clinical setting. The study showed that a single Bluetooth link was robust and electromagnetically compatible with the tested electronic medical devices.

This paper aims to provide an overview of the rationale and basic principles guiding the governance of genomic testing services, to clarify their objectives, and allocate and define responsibilities among stakeholders in a health-care system, with a special focus on the EU countries. Particular attention is paid to issues pertaining to pricing and reimbursement policies, the availability of essential genomic tests which differs between various countries owing to differences in disease prevalence and public health relevance, the prescribing and use of genomic testing services according to existing or new guidelines, budgetary and fiscal control, the balance between price and access to innovative testing, monitoring and evaluation for cost-effectiveness and safety, and the development of research capacity. We conclude that addressing the specific items put forward in this article will help to create a robust policy in relation to pricing and reimbursement in genomic medicine. This will contribute to an effective and sustainable health-care system and will prove beneficial to the economy at large. © 2016 S. Karger AG, Basel.

Workarounds and Test Results Follow-up in Electronic Health Record-Based Primary Care.

2016-01-01

Electronic health records (EHRs) have potential to facilitate reliable communication and follow-up of test results. However, limitations in EHR functionality remain, leading practitioners to use workarounds while managing test results. Workarounds can lead to patient safety concerns and signify indications as to how to build better EHR systems that meet provider needs. To understand why primary care practitioners (PCPs) use workarounds to manage test results by analyzing data from a previously conducted national cross-sectional survey on test result management. We conducted a secondary data analysis of quantitative and qualitative data from a national survey of PCPs practicing in the Department of Veterans Affairs (VA) and explored the use of workarounds in test results management. We used multivariate logistic regression analysis to examine the association between key sociotechnical factors that could affect test results follow-up (e.g., both technology-related and those unrelated to technology, such as organizational support for patient notification) and workaround use. We conducted a qualitative content analysis of free text survey data to examine reasons for use of workarounds. Of 2554 survey respondents, 1104 (43%) reported using workarounds related to test results management. Of these 1028 (93%) described the type of workaround they were using; 719 (70%) reported paper-based methods, while 230 (22%) used a combination of paper- and computer-based workarounds. Primary care practitioners who self-reported limited administrative support to help them notify patients of test results or described an instance where they personally (or a colleague) missed results, were more likely to use workarounds (p=0.02 and p=0.001, respectively). Qualitative analysis identified three main reasons for workaround use: 1) as a memory aid, 2) for improved efficiency and 3) for facilitating internal and external care coordination. Workarounds to manage EHR-based test results are common, and their use results from unmet provider information management needs. Future EHRs and the respective work systems around them need to evolve to meet these needs.

QUALMAT project aimed at improving quality of maternal and newborn care in selected health care facilities in three African countries. An electronic clinical decision support system was implemented to support providers comply with established standards in antenatal and childbirth care. Given that health care resources are limited and interventions differ in their potential impact on health and costs (efficiency), this study aimed at assessing cost-effectiveness of the system in Tanzania. This was a quantitative pre- and post- intervention study involving 6 health centres in rural Tanzania. Cost information was collected from health provider's perspective. Outcome information was collected through observation of the process of maternal care. Incremental cost-effectiveness ratios for antenatal and childbirth care were calculated with testing of four models where the system was compared to the conventional paper-based approach to care. One-way sensitivity analysis was conducted to determine whether changes in process quality score and cost would impact on cost-effectiveness ratios. Economic cost of implementation was 167,318 USD, equivalent to 27,886 USD per health center and 43 USD per contact. The system improved antenatal process quality by 4.5% and childbirth care process quality by 23.3% however these improvements were not statistically significant. Base-case incremental cost-effectiveness ratios of the system were 2469 USD and 338 USD per 1% change in process quality for antenatal and childbirth care respectively. Cost-effectiveness of the system was sensitive to assumptions made on costs and outcomes. Although the system managed to marginally improve individual process quality variables, it did not have significant improvement effect on the overall process quality of care in the short-term. A longer duration of usage of the electronic clinical decision support system and retention of staff are critical to the efficiency of the system and can reduce the invested resources. Realization of gains from the system requires effective implementation and an enabling healthcare system. Registered clinical trial at www.clinicaltrials.gov ( NCT01409824 ). Registered May 2009.

Previous studies have noted a high (41%) prevalence and poor discharge summary communication of pending laboratory (lab) tests at the time of hospital discharge for general medical patients. However, the prevalence and communication of pending labs within a high-risk population, specifically those patients discharged to sub-acute care (i.e., skilled nursing, rehabilitation, long-term care), remains unknown. To determine the prevalence and nature of lab tests pending at hospital discharge and their inclusion within hospital discharge summaries, for common sub-acute care populations. Retrospective cohort study. Stroke, hip fracture, and cancer patients discharged from a single large academic medical center to sub-acute care, 2003-2005 (N = 564) Pending lab tests were abstracted from the laboratory information system (LIS) and from each patient's discharge summary, then grouped into 14 categories and compared. Microbiology tests were sub-divided by culture type and number of days pending prior to discharge. Of sub-acute care patients, 32% (181/564) were discharged with pending lab tests per the LIS; however, only 11% (20/181) of discharge summaries documented these. Patients most often left the hospital with pending microbiology tests (83% [150/181]), particularly blood and urine cultures, and reference lab tests (17% [30/181]). However, 82% (61/74) of patients' pending urine cultures did not have 24-hour preliminary results, and 19% (13/70) of patients' pending blood cultures did not have 48-hour preliminary results available at the time of hospital discharge. Approximately one-third of the sub-acute care patients in this study had labs pending at discharge, but few were documented within hospital discharge summaries. Even after considering the availability of preliminary microbiology results, these omissions remain common. Future studies should focus on improving the communication of pending lab tests at discharge and evaluating the impact that this improved communication has on patient outcomes.

Holistic self-management education and support: a proposed public health model for improving women's health in Zimbabwe.

PubMed

Kanchense, Jane Handina Murigwa

2006-08-01

The primary health care model of public health has been implemented in many countries around the globe since the Declaration of Alma Ata in 1978, without pilot testing the primary health care model. Therefore, many public health researchers have sought methods of improving primary health care by creating evidence-based models. Many of these researchers recognize the role of behavioral models in public health. These offshoots of primary health care include the ecological, care, central human capabilities, and the SPECIES models. Holistic self-management education and support is a capacity-building philosophy that ensures active involvement of consumers of health care in the planning and implementation and evaluation of health care services. It helps consumers of health care to achieve the desired improved quality of health and life in managing and sustaining their health at the grassroots level. The care model addresses disease management ideals of the in the original primary health care model. The SPECIES model addresses those aspects of the primary health care model that include the cultural and social factors, as well as individual health education and support in the original primary health care model. The ecological model offers an improvement of the socioeconomic ideal in the original primary health care model. Improving the health of individuals will prevent illness, thereby reducing health care costs and lessening the current strain on an overburdened health care system in Zimbabwe. Holistic self-management education and support links health care delivery systems with social processes. It is a best practices model that could better serve Zimbabwean girls and women by contributing positively to the national challenges in health care, thereby meeting the Zimbabwean primary health care and safe motherhood goals. It is here recommended that holistic self-management education and support must be pilot tested before being adopted as the most appropriate model for ensuring population health.

The excess risk of diabetic complications in African Americans may be due to poor glycemic control arising from suboptimal use and/or quality of diabetes-related health care. However, little is known about racial differences in these factors, particularly in urban populations. We conducted a cross-sectional study using medical claims and encounter data on 1,106 adults with diabetes aged > or =30 years who were members of an urban managed care organization in capitated health plans. We examined health care and routine hemoglobin A(1c) (HbA(1c)) testing in a biracial cohort for 12 months. We then followed individuals for an additional 12 months, using a retrospective cohort design, to determine how this health care predicted subsequent emergency room visits. On average, compared with their white counterparts, African Americans had fewer primary care visits (85% vs. 91% with four or more visits) and fewer HbA(1c) tests (56% vs. 68% with two or more HbA(1c) tests) (all P < 0.05). Likewise, in the subset who underwent one or more HbA(1c) measurement (n = 855), African Americans displayed poorer glycemic control (HbA(1c) 9.1 +/- 2.9%) than whites (8.5 +/- 2.2%; P = 0.001). In multivariate analyses, racial differences in visit frequency and HbA(1c) testing were attenuated by adjustment for age, sex, and type of capitated plan and did not remain statistically significant. The relationship of health care to subsequent emergency room visits differed by race; in African Americans, fewer primary care visits and HbA(1c) tests predicted greater risk of emergency room visits. Even in a capitated, managed care setting, urban African Americans with diabetes are less likely than their white counterparts to undergo routine primary care visits and laboratory testing and are more likely to have suboptimal glycemic control. Differences in age, sex, and insurance type seemed to explain some of the disparities. Future research should determine the individual contributions of physician, patient, and system factors to the racial disparities in health care.

HIV testing and counseling services in Africa began in the early 1990s, with limited availability and coverage. Fears of stigma and discrimination, complex laboratory systems, and lack of available care and treatment services hampered expansion. Use of rapid point-of-care tests, introduction of services to prevent mother-to-child transmission, and increasing provision of antiretroviral drugs were key events in the late 1990s and early 2000s that facilitated the expansion of HIV testing and counseling services. Innovations in service delivery included providing HIV testing in both clinical and community sites, including mobile and home testing. Promotional campaigns were conducted in many countries, and evolutions in policies and guidance facilitated expansion and uptake. Support from President's Emergency Plan for AIDS Relief and national governments, other donors, and the Global Fund for AIDS, Tuberculosis, and Malaria contributed to significant increases in the numbers of persons tested in many countries. Quality of both testing and counseling, limited number of health care workers, uptake by couples, and effectiveness of linkages and referral systems remain challenges. Expansion of antiretroviral treatment, especially in light of the evidence that treatment contributes to prevention of transmission, will require greater yet strategic coverage of testing services, especially in clinical settings and in combination with other high-impact HIV prevention strategies. Continued support from President's Emergency Plan for AIDS Relief, governments, and other donors is required for the expansion of testing needed to achieve international targets for the scale-up of treatment and universal access to knowledge of HIV status.

To investigate the reliability, validity and feasibility of the RAFAELA workforce planning system (including the Oulu patient classification system - OPCq), before deciding on implementation in Dutch hospitals. The complexity of care, budgetary restraints and demand for high-quality patient care have ignited the need for transparent hospital workforce planning. Nurses from 12 wards of two university hospitals were trained to test the reliability of the OPCq by investigating the absolute agreement of nursing care intensity (NCI) measurements among nurses. Validity was tested by assessing whether optimal NCI/nurse ratio, as calculated by a regression analysis in RAFAELA, was realistic. System feasibility was investigated through a questionnaire among all nurses involved. Almost 67 000 NCI measurements were performed between December 2013 and June 2014. Agreement using the OPCq varied between 38% and 91%. For only 1 in 12 wards was the optimal NCI area calculated judged as valid. Although the majority of respondents was positive about the applicability and user-friendliness, RAFAELA was not accepted as useful workforce planning system. Nurses' performance using the RAFAELA system did not warrant its implementation. Hospital managers should first focus on enlarging the readiness of nurses regarding the implementation of a workforce planning system. © 2015 John Wiley & Sons Ltd.

Physician satisfaction with electronic medical records has often been poor. Usability has frequently been identified as a source for decreased satisfaction. While surveys can identify many issues, and are logistically easier to administer, they may miss issues identified using other methods This study sought to understand the level of physician satisfaction and usability issues associated with a critical care clinical information system (eCritical Alberta) implemented throughout the province of Alberta, Canada. All critical care attending physicians using the system were invited to participate in an online survey. Questions included components of the User Acceptance of Information Technology and Usability Questionnaire as well as free text feedback on system components. Physicians were also invited to participate in a think aloud test using simulated scenarios. The transcribed think aloud text and questionnaire were subjected to textual analysis. 82% of all eligible physicians completed the on-line survey (n = 61). Eight physicians were invited and seven completed the think aloud test. Overall satisfaction with the system was moderate. Usability was identified as a significant factor contributing to satisfaction. The major usability factors identified were system response time and layout. The think aloud component identified additional factors beyond those identified in the on-line survey. This study found a modestly high level of physician satisfaction with a province-wide clinical critical care information system. Usability continues to be a significant factor in physician satisfaction. Using multiple methods of evaluation can capture the benefits of a large sample size and deeper understanding of the issues.

To investigate factors influencing the adoption of kangaroo mother care in different contexts. We searched PubMed, Embase, Scopus, Web of Science and the World Health Organization's regional databases, for studies on "kangaroo mother care" or "kangaroo care" or "skin-to-skin care" from 1 January 1960 to 19 August 2015, without language restrictions. We included programmatic reports and hand-searched references of published reviews and articles. Two independent reviewers screened articles and extracted data on carers, health system characteristics and contextual factors. We developed a conceptual model to analyse the integration of kangaroo mother care in health systems. We screened 2875 studies and included 112 studies that contained qualitative data on implementation. Kangaroo mother care was applied in different ways in different contexts. The studies show that there are several barriers to implementing kangaroo mother care, including the need for time, social support, medical care and family acceptance. Barriers within health systems included organization, financing and service delivery. In the broad context, cultural norms influenced perceptions and the success of adoption. Kangaroo mother care is a complex intervention that is behaviour driven and includes multiple elements. Success of implementation requires high user engagement and stakeholder involvement. Future research includes designing and testing models of specific interventions to improve uptake.

Problem Current models of health care quality improvement do not explicitly describe the role of health professions education. The authors propose the Exemplary Care and Learning Site (ECLS) model as an approach to achieving continual improvement in care and learning in the clinical setting. Approach From 2008–2012, an iterative, interactive process was used to develop the ECLS model and its core elements—patients and families informing process changes; trainees engaging both in care and the improvement of care; leaders knowing, valuing, and practicing improvement; data transforming into useful information; and health professionals competently engaging both in care improvement and teaching about care improvement. In 2012–2013, a three-part feasibility test of the model, including a site self-assessment, an independent review of each site’s ratings, and implementation case stories, was conducted at six clinical teaching sites (in the United States and Sweden). Outcomes Site leaders reported the ECLS model provided a systematic approach toward improving patient (and population) outcomes, system performance, and professional development. Most sites found it challenging to incorporate the patients and families element. The trainee element was strong at four sites. The leadership and data elements were self-assessed as the most fully developed. The health professionals element exhibited the greatest variability across sites. Next Steps The next test of the model should be prospective, linked to clinical and educa tional outcomes, to evaluate whether it helps care delivery teams, educators, and patients and families take action to achieve better patient (and population) outcomes, system performance, and professional development.

Individuals with spina bifida (SB) are vulnerable to chronic skin complications such as wounds on the buttocks and lower extremities. Most of these complications can be prevented with adherence to self-care routines. We have developed a mobile health (mHealth) system for supporting self-care and management of skin problems called SkinCare as part of an mHealth suite called iMHere (interactive Mobile Health and Rehabilitation). The objective of this research is to develop an innovative mHealth system to support self-skincare tasks, skin condition monitoring, adherence to self-care regimens, skincare consultation, and secure two-way communications between patients and clinicians. In order to support self-skincare tasks, the SkinCare app requires three main functions: (1) self-care task schedule and reminders, (2) skin condition monitoring and communications that include imaging, information about the skin problem, and consultation with clinician, and (3) secure two-way messaging between the patient and clinician (wellness coordinator). The SkinCare system we have developed consists of the SkinCare app, a clinician portal, and a two-way communication protocol connecting the two. The SkinCare system is one component of a more comprehensive system to support a wellness program for individuals with SB. The SkinCare app has several features that include reminders to perform daily skin checks as well as the ability to report skin breakdown and injury, which uses a combination of skin images and descriptions. The SkinCare app provides reminders to visually inspect one's skin as a preventative measure, often termed a "skin check." The data is sent to the portal where clinicians can monitor patients' conditions. Using the two-way communication, clinicians can receive pictures of the skin conditions, track progress in healing over time, and provide instructions for how to best care for the wound. The system was capable of supporting self-care and adherence to regimen, monitoring adherence, and supporting clinician engagement with patients, as well as testing its feasibility in a long-term implementation. The study shows the feasibility of a long-term implementation of skincare mHealth systems to support self-care and two-way interactions between patients and clinicians.

Despite robust evidence to guide clinical care, most patients with diabetes do not meet all goals of risk factor control. Improved patient-provider communication during time-limited primary care visits may represent one strategy for improving diabetes care. We designed a controlled, cluster-randomized, multi-site intervention (Pre-Visit Prioritization for Complex Patients with Diabetes) that enables patients with poorly controlled type 2 diabetes to identify their top priorities prior to a scheduled visit and sends these priorities to the primary care physician progress note in the electronic medical record. In this paper, we describe strategies to address challenges to implementing our health IT-based intervention study within a large health care system. This study is being conducted in 30 primary care practices within a large integrated care delivery system in Northern California. Over a 12-week period (3/1/2015-6/6/2015), 146 primary care physicians consented to enroll in the study (90.1%) and approved contact with 2496 of their patients (97.6%). Implementation challenges included: (1) navigating research vs. quality improvement requirements; (2) addressing informed consent considerations; and (3) introducing a new clinical tool into a highly time-constrained workflow. Strategies for successfully initiating this study included engagement with institutional leaders, Institutional Review Board members, and clinical stakeholders at multiple stages both before and after notice of Federal funding; flexibility by the research team in study design; and strong support from institutional leadership for "self-learning health system" research. By paying careful attention to identifying and collaborating with a wide range of key clinical stakeholders, we have shown that researchers embedded within a learning care system can successfully apply rigorous clinical trial methods to test new care innovations.

Although the advantages of introducing point of care testing for syphilis in antenatal care (ANC) are well documented, there is little evidence on how to address structural issues within health systems. A better understanding of how these interventions work in a range of settings and contexts is needed in order to overcome bottlenecks at health system level. To better understand the relationships between implementation and context we developed and implemented an intervention focused on integrating a rapid screening test for syphilis in ANC services in rural primary health care facilities in Burkina Faso. This manuscript describes the intervention and reports on feasibility and acceptability of the intervention, the facilitators and barriers to the implementation of this intervention and the likelihood that point of care test for syphilis will become routinely incorporated in practice. In Kaya Health and Demographic Surveillance System (Kaya HDSS), all 7 primary healthcare facilities were selected for intervention in 2013. A participatory approach was used to design and implement an antenatal syphilis screening intervention. The Normalization Process Model (NPM) proposed by May et al. was adapted in order to identify barriers and facilitators and to explore the likelihood to become routinely incorporated in practice. Registers, Observations (n = 14 ANC 1) of interactions between patients and health workers during ANC and interviews with health workers (n = 14) were our data sources. An intervention that included onsite training, provision of supplies and medicines, quality control and supervision was implemented in 7 health facilities in 2013. Rapid syphilis test and treatment were delivered during ANC within the examination room with no specific additional mechanism regarding staff organization. The perceived barriers were lack of training of all staff, workload, stock-outs of consumables and lack of motivation of staff. Key facilitators included political environment, ease of use of test and acceptability to pregnant women. Onsite testing for antenatal syphilis is a feasible and acceptable intervention in ANC at primary health facility in Burkina Faso. The point-of care test for syphilis is more likely to be acceptable by health workers as routine service and incorporated as a normal practice. The study was retrospectively registered on ClinicalTrials.gov under the Trial Registration Number NCT03156751 .

HIV self-testing allows HIV testing at any place and time and without health workers. HIV self-testing may thus be particularly useful for female sex workers (FSWs), who should test frequently but face stigma and financial and time barriers when accessing healthcare facilities. We conducted a cluster-randomized controlled health systems trial among FSWs in Kampala, Uganda, to measure the effect of 2 HIV self-testing delivery models on HIV testing and linkage to care outcomes. FSW peer educator groups (1 peer educator and 8 participants) were randomized to either (1) direct provision of HIV self-tests, (2) provision of coupons for free collection of HIV self-tests in a healthcare facility, or (3) standard of care HIV testing. We randomized 960 participants in 120 peer educator groups from October 18, 2016, to November 16, 2016. Participants' median age was 28 years (IQR 24-32). Our prespecified primary outcomes were self-report of any HIV testing at 1 month and at 4 months; our prespecified secondary outcomes were self-report of HIV self-test use, seeking HIV-related medical care and ART initiation. In addition, we analyzed 2 secondary outcomes that were not prespecified: self-report of repeat HIV testing-to understand the intervention effects on frequent testing-and self-reported facility-based testing-to quantify substitution effects. Participants in the direct provision arm were significantly more likely to have tested for HIV than those in the standard of care arm, both at 1 month (risk ratio [RR] 1.33, 95% CI 1.17-1.51, p < 0.001) and at 4 months (RR 1.14, 95% CI 1.07-1.22, p < 0.001). Participants in the direct provision arm were also significantly more likely to have tested for HIV than those in the facility collection arm, both at 1 month (RR 1.18, 95% CI 1.07-1.31, p = 0.001) and at 4 months (RR 1.03, 95% CI 1.01-1.05, p = 0.02). At 1 month, fewer participants in the intervention arms had sought medical care for HIV than in the standard of care arm, but these differences were not significant and were reduced in magnitude at 4 months. There were no statistically significant differences in ART initiation across study arms. At 4 months, participants in the direct provision arm were significantly more likely to have tested twice for HIV than those in the standard of care arm (RR 1.51, 95% CI 1.29-1.77, p < 0.001) and those in the facility collection arm (RR 1.22, 95% CI 1.08-1.37, p = 0.001). Participants in the HIV self-testing arms almost completely replaced facility-based testing with self-testing. Two adverse events related to HIV self-testing were reported: interpersonal violence and mental distress. Study limitations included self-reported outcomes and limited generalizability beyond FSWs in similar settings. In this study, HIV self-testing appeared to be safe and increased recent and repeat HIV testing among FSWs. We found that direct provision of HIV self-tests was significantly more effective in increasing HIV testing among FSWs than passively offering HIV self-tests for collection in healthcare facilities. HIV self-testing could play an important role in supporting HIV interventions that require frequent HIV testing, such as HIV treatment as prevention, behavior change for transmission reduction, and pre-exposure prophylaxis.

2017-11-21

In today's health care environment, increasing costs and inadequate medical resources have created a worldwide need for more affordable diagnostic tools that are also portable, fast, and easy to use. To address this issue, numerous research and commercial efforts have focused on developing rapid diagnostic technologies; however, the efficacy of existing systems has been hindered by usability problems or high production costs, making them infeasible for deployment in at-home, point-of-care (POC), or resource-limited settings. The aim of this study was to create a low-cost optical reader system that integrates with any smart device and accepts any type of rapid diagnostic test strip to provide fast and accurate data collection, sample analysis, and diagnostic result reporting. An iterative design methodology was employed by a multidisciplinary research team to engineer three versions of a portable diagnostic testing device that were evaluated for usability and overall user receptivity. Repeated design critiques and usability studies identified a number of system requirements and considerations (eg, software compatibility, biomatter contamination, and physical footprint) that we worked to incrementally incorporate into successive system variants. Our final design phase culminated in the development of Tidbit, a reader that is compatible with any Wi-Fi-enabled device and test strip format. The Tidbit includes various features that support intuitive operation, including a straightforward test strip insertion point, external indicator lights, concealed electronic components, and an asymmetric shape, which inherently signals correct device orientation. Usability testing of the Tidbit indicates high usability for potential user communities. This study presents the design process, specification, and user reception of the Tidbit, an inexpensive, easy-to-use, portable optical reader for fast, accurate quantification of rapid diagnostic test results. Usability testing suggests that the reader is usable among and can benefit a wide group of potential users, including in POC contexts. Generally, the methodology of this study demonstrates the importance of testing these types of systems with potential users and exemplifies how iterative design processes can be employed by multidisciplinary research teams to produce compelling technological solutions. ©Jess Hohenstein, Dakota O'Dell, Elizabeth L Murnane, Zhengda Lu, David Erickson, Geri Gay.

Parental care is a widespread phenomenon observed in many diverse taxa. Neuroendocrine systems have long been thought to play an important role in stimulating the onset of parental behavior. In most birds with altricial young, circulating prolactin (PRL) levels are low during non-breeding times and significantly increase during late incubation and early post-hatch chick care. Because of this pattern, PRL has been suggested to be involved in the initiation of parental care in birds, but rarely has this hypothesis been causally tested. To begin testing the hypothesis, we inhibited the release of endogenous PRL with bromocriptine (BR) on the 3days prior to hatching in incubating parents and the first 2days of post-hatch care, when PRL was found to be highest in zebra finches. Nest temperatures were recorded during all 5days and parental behavior was recorded on days 1-2 post-hatch. In addition to hormonal systems, reproductive experience may also influence parental care; therefore, we tested age-matched inexperienced and experienced pairs in each group. BR either eliminated or drastically reduced chick brooding and feeding behavior, resulting in decreased nest temperatures on days 1 and 2 post-hatch. Experienced control birds fed chicks more than inexperienced birds and control females fed more than males. Chick feeding behavior was positively correlated in control male-female pairs, but not in BR pairs. This is one of the few causal studies to demonstrate that PRL is necessary for post-hatch care in a biparental songbird, and is the first to show this effect in zebra finches.

The mechanisms through which the relationships among public institutions, private providers and families affect care and service provision systems are puzzling. How can we understand the mechanisms in these contexts? Which elements should we explore to capture the complexity of care provision? The aim of our study is to provide a framework that can help read and reframe these puzzling care provision mechanisms in a welfare mix context. First, we develop a theoretical framework for understanding how service provision occurs in care systems that are characterised by a variety of relationships between multiple actors, using an evidence-based approach that looks at both public and private expenditures and the number of users relative to the level of needs coverage and compared with declared values and political rhetoric. Second, we test this framework in two case studies built on data from two prominent Italian regions, Lombardy and Emilia-Romagna. We argue that service provision models depend on the interplay among six conceptual elements: policy values, governance rules, resources, nature of the providers, service standards and eligibility criteria. Our empirical study shows that beneath the relevant differences in values and political rhetoric between the case studies of the two Italian regions, there is a surprising isomorphism in service standards and the levels of covering the population's needs. The suggested framework appears to be effective and feasible; it fosters interdisciplinary approaches and supports policy-making discussions. This study may contribute to deepening knowledge about public care service provision and institutional arrangements, which can be used to promote more effective reforms and may advance future research. Although the framework was tested on the Italian welfare system, it can be used to assess many different systems.

Development of Probabilistic Life Prediction Methodologies and Testing Strategies for MEMS and CMC's

Jadaan, Osama

2003-01-01

This effort is to investigate probabilistic life prediction methodologies for ceramic matrix composites and MicroElectroMechanical Systems (MEMS) and to analyze designs that determine stochastic properties of MEMS. For CMC's this includes a brief literature survey regarding lifing methodologies. Also of interest for MEMS is the design of a proper test for the Weibull size effect in thin film (bulge test) specimens. The Weibull size effect is a consequence of a stochastic strength response predicted from the Weibull distribution. Confirming that MEMS strength is controlled by the Weibull distribution will enable the development of a probabilistic design methodology for MEMS - similar to the GRC developed CARES/Life program for bulk ceramics. A main objective of this effort is to further develop and verify the ability of the Ceramics Analysis and Reliability Evaluation of Structures/Life (CARES/Life) code to predict the time-dependent reliability of MEMS structures subjected to multiple transient loads. A second set of objectives is to determine the applicability/suitability of the CARES/Life methodology for CMC analysis, what changes would be needed to the methodology and software, and if feasible, run a demonstration problem. Also important is an evaluation of CARES/Life coupled to the ANSYS Probabilistic Design System (PDS) and the potential of coupling transient reliability analysis to the ANSYS PDS.

Background To enable primary care medical practitioners to generate a range of possible service delivery models for genetic counselling services and critically assess their suitability. Methods Modified nominal group technique using in primary care professional development workshops. Results 37 general practitioners in Wales, United Kingdom too part in the nominal group process. The practitioners who attended did not believe current systems were sufficient to meet anticipated demand for genetic services. A wide range of different service models was proposed, although no single option emerged as a clear preference. No argument was put forward for genetic assessment and counselling being central to family practice, neither was there a voice for the view that the family doctor should become skilled at advising patients about predictive genetic testing and be able to counsel patients about the wider implications of genetic testing for patients and their family members, even for areas such as common cancers. Nevertheless, all the preferred models put a high priority on providing the service in the community, and often co-located in primary care, by clinicians who had developed expertise. Conclusion There is a need for a wider debate about how healthcare systems address individual concerns about genetic concerns and risk, especially given the increasing commercial marketing of genetic tests.

Use of electronic secure messaging (SM) is rapidly growing in various healthcare settings. However, there is a large number of patients that choose not use SM or use it minimally. Thus, understanding preferences for patient-provider communication modalities is critically important, particularly among military healthcare beneficiaries. The purpose of this study was to assess preferences for patient-provider communication modalities (in person, telephone, SM, or mail) among a sample of patients, providers, and staff located at five Air Force military treatment facilities across the USA. We recruited patients, providers, and staff, from five family health clinics to complete a short survey. We measured participants' preferences for communication modality for various healthcare concerns, such as responses to non-urgent medical questions, test results, and medication renewal information. We also measured satisfaction with MiCare, the Air Force's SM system. We conducted chi-square analyses and Fisher's exact tests to assess differences in communication preferences by patients, providers, and staff and we computed frequencies in satisfaction responses. We found that while providers and staff (N = 70) prefer to communicate with patients about various healthcare concerns online through MiCare, patients (N = 1,260) prefer to communicate in-person or through the telephone. Patients were generally satisfied with MiCare; however, there was a large proportion of patients who were undecided about MiCare's impact on the quality of care they received (40.3%). Additionally, although the majority of providers and staff believed MiCare improved their efficiency (58.0%) and communication with patients (72.3%), 65.7% of providers and staff believed MiCare had increased their workload. MiCare is a promising tool to improve patient-provider communication. However, future studies are needed to better understand why patients within the military healthcare system prefer communication modalities other than MiCare and to identify strategies to decrease provider and staff workloads while using MiCare.

Improving medication safety at the point of care--particularly for high-risk drugs--is a major concern of nursing administrators. The medication errors most likely to cause harm are administration errors related to infusion of high-risk medications. An intravenous medication safety system is designed to prevent high-risk infusion medication errors and to capture continuous quality improvement data for best practice improvement. Initial testing with 50 systems in 2 units at Vanderbilt University Medical Center revealed that, even in the presence of a fully mature computerized prescriber order-entry system, the new safety system averted 99 potential infusion errors in 8 months.

Optimal critical test result communication is a Joint Commission national patient safety goal and requires documentation of closed-loop communication among care providers in the medical record. Electronic alert notification systems can facilitate an auditable process for creating alerts for transmission and acknowledgement of critical test results. We evaluated the impact of a patient safety initiative with an alert notification system on reducing critical results lacking documented communication, and assessed potential overuse of the alerting system for communicating results. We implemented an alert notification system-Alert Notification of Critical Results (ANCR)-in January 2010. We reviewed radiology reports finalised in 2009-2014 which lacked documented communication between the radiologist and another care provider, and assessed the impact of ANCR on the proportion of such reports with critical findings, using trend analysis over 10 semiannual time periods. To evaluate potential overuse of ANCR, we assessed the proportion of reports with non-critical results among provider-communicated reports. The proportion of reports with critical results among reports without documented communication decreased significantly over 4 years (2009-2014) from 0.19 to 0.05 (p<0.0001, Cochran-Armitage trend test). The proportion of provider-communicated reports with non-critical results remained unchanged over time before and after ANCR implementation (0.20 to 0.15, p=0.45, Cochran-Armitage trend test). A patient safety initiative with an alert notification system reduced the proportion of critical results among reports lacking documented communication between care providers. We observed no change in documented communication of non-critical results, suggesting the system did not promote overuse. Future studies are needed to evaluate whether such systems prevent subsequent patient harm. Published by the BMJ Publishing Group Limited.

Objectives The objective of this study is to investigate differences in the diagnosis and management of systemic lupus erythematosus (SLE) by primary care and specialist physicians in a population-based registry. Methods This study includes individuals from the 2009 Indian Health Service lupus registry population with a diagnosis of SLE documented by either a primary care provider or specialist. SLE classification criteria, laboratory testing, and medication use at any time during the course of disease were determined by medical record abstraction. Results Of the 320 individuals with a diagnosis of SLE, 249 had the diagnosis documented by a specialist, with 71 documented by primary care. Individuals with a specialist diagnosis of SLE were more likely to have medical record documentation of meeting criteria for SLE by all criteria sets (American College of Rheumatology, 79% vs 22%; Boston Weighted, 82% vs 32%; and Systemic Lupus International Collaborating Clinics, 83% vs 35%; p < 0.001 for all comparisons). In addition, specialist diagnosis was associated with documentation of ever having been tested for anti-double-stranded DNA antibody and complement 3 and complement 4 ( p < 0.001). Documentation of ever receiving hydroxychloroquine was also more common with specialist diagnosis (86% vs 64%, p < 0.001). Conclusions Within the population studied, specialist diagnosis of SLE was associated with a higher likelihood of having SLE classification criteria documented, being tested for biomarkers of disease, and ever receiving treatment with hydroxychloroquine. These data support efforts both to increase specialist access for patients with suspected SLE and to provide lupus education to primary care providers.

Evidence for Elimination (E4E) is a collaborative project established in 2012 as part of the INSPIRE (INtegrating and Scaling up PMTCT through Implementation REsearch) initiative. E4E is a cluster-randomized trial with 2 arms; Standard of care and "POC Plus" [in which point-of-care (POC) CD4 devices and related counseling support are provided]; aimed at improving retention-in-care of HIV-infected pregnant women and mothers. In November 2013, Zimbabwe adopted Option B+ for HIV-positive pregnant women under which antiretroviral treatment eligibility is no longer based on CD4 count. However, Ministry of Health and Child Care guidelines still require baseline and 6-monthly CD4 testing for treatment monitoring, until viral load testing becomes widely available. Considering the current limited capacity for viral-load testing, the significant investments in CD4 testing already made and the historical reliance on CD4 by health care workers for determining eligibility for antiretroviral treatment, E4E seeks to compare the impact of the provision of POC CD4 technology and early knowledge of CD4 levels on retention-in-care at 12 months, with the current standard of routine, laboratory-based CD4 testing. The study also compares rates of initiation and time-to-initiation between the 2 arms and according to level of maternal CD4 count, the cost of retaining HIV-positive pregnant women in care and the acceptability and feasibility of POC CD4 in the context of Option B+. Outcome measures are derived from routine health systems data. E4E will provide data on POC CD4 testing and retention-in-care associated with Option B+ and serve as an early learning platform to inform implementation of Option B+ in Zimbabwe.

Curricular options for teaching and evaluating surgery residents' outcomes in systems-based practice are limited. A Web-based curriculum, MDContent, developed collaboratively by experts in business and surgery, provides learning experiences in the business of health care. The purpose of this study is to describe surgery residents' experience and learning outcomes associated with the curriculum. Twenty-eight PGY3 to 6 general and plastic surgery residents were enrolled in the Web-based curriculum. Twenty-two residents (79%) completed the pretest, 11 modules, the post-test, and the course evaluation by the end of 1 year. The pretest and the post-test were 30-item multiple-choice exams based on a blueprint of the curricular objectives. Descriptive statistics were calculated on course evaluation and module completion data. Paired t-tests were used to compare pre- and post-test performance. Content analysis was performed on course evaluation written responses. Residents' performance on the multiple choice exam improved significantly (p = 0.0001) from the pre-test (mean 59%, SD 12.1) to the post-test (mean 78%, SD 9.4), with an average gain of 19 percentage points. Participants rated their Web-based learning experience as very positive, with a majority of residents agreeing that the content was well organized, relevant, and an excellent learning experience around content not taught elsewhere in medical school or residency. Participation in a Web-based curriculum on health care business improves surgery residents' knowledge about health care business concepts and principles. Residents with varying levels of interest in health care business provide positive ratings about their learning experience and indications that lessons learned would be applied in their clinical practice. MDContent is a feasible and effective method for teaching and assessing systems-based practice concepts. Copyright © 2010 American College of Surgeons. Published by Elsevier Inc.

Most patients presenting to US Emergency Departments (ED) with chest pain are hospitalized for comprehensive testing. These evaluations cost the US health system >$10 billion annually, but have a diagnostic yield for acute coronary syndrome (ACS) of <10%. The history/ECG/age/risk factors/troponin (HEART) Pathway is an accelerated diagnostic protocol (ADP), designed to improve care for patients with acute chest pain by identifying patients for early ED discharge. Prior efficacy studies demonstrate that the HEART Pathway safely reduces cardiac testing, while maintaining an acceptably low adverse event rate. The purpose of this study is to determine the effectiveness of HEART Pathway ADP implementation within a health system. This controlled before-after study will accrue adult patients with acute chest pain, but without ST-segment elevation myocardial infarction on electrocardiogram for two years and is expected to include approximately 10,000 patients. Outcomes measures include hospitalization rate, objective cardiac testing rates (stress testing and angiography), length of stay, and rates of recurrent cardiac care for participants. In pilot data, the HEART Pathway decreased hospitalizations by 21%, decreased hospital length (median of 12 hour reduction), without increasing adverse events or recurrent care. At the writing of this paper, data has been collected on >5000 patient encounters. The HEART Pathway has been fully integrated into health system electronic medical records, providing real-time decision support to our providers. We hypothesize that the HEART Pathway will safely reduce healthcare utilization. This study could provide a model for delivering high-value care to the 8-10 million US ED patients with acute chest pain each year.

Despite accumulating evidence indicating that collecting patient-reported outcomes (PROs) and transferring results to the treating health professional in real time has the potential to improve patient well-being and cancer outcomes, this practice is not widespread. The aim of this study was to test the feasibility and acceptability of PROMPT-Care (Patient Reported Outcome Measures for Personalized Treatment and Care), a newly developed electronic health (eHealth) system that facilitates PRO data capture from cancer patients, data linkage and retrieval to support clinical decisions and patient self-management, and data retrieval to support ongoing evaluation and innovative research. We developed an eHealth system in consultation with content-specific expert advisory groups and tested it with patients receiving treatment or follow-up care in two hospitals in New South Wales, Australia, over a 3-month period. Participants were recruited in clinic and completed self-report Web-based assessments either just before their upcoming clinical consultation or every 4 weeks if in follow-up care. A mixed methods approach was used to evaluate feasibility and acceptability of PROMPT-Care; data collected throughout the study informed the accuracy and completeness of data transfer procedures, and extent of missing data was determined from participants' assessments. Patients participated in cognitive interviews while completing their first assessment and completed evaluation surveys and interviews at study-end to assess system acceptability and usefulness of patient self-management resources, and oncology staff were interviewed at study-end to determine the acceptability and perceived usefulness of real-time PRO reporting. A total of 42 patients consented to the study; 7 patients were withdrawn before starting the intervention primarily because of changes in eligibility. Overall, 35 patients (13 on treatment and 22 in follow-up) completed 67 assessments during the study period. Mean completeness of patient-reported data was 93%, with 100% accuracy of data transfer. Ten patients completed cognitive interviews, 28 completed evaluation surveys, and 14 completed evaluation interviews at study-end. PROMPT-Care patient acceptability was high-100% (28/28) reported the time to complete the Web-based assessments (average 15 min) as about right, most willing to answer more questions (79%, 22/28 yes), 96% (27/28) found the Web-based assessment easier or same as completing a paper copy, and they valued the self-management resources . Oncology staff (n=5) also reported high acceptability and potential feasibility of the system. Patients and oncology staff found the PROMPT-Care system to be highly acceptable, and the results suggest that it would be feasible to implement it into an oncology setting. Suggested modifications to the patient assessment survey, clinician access to the reports, and system requirements will be made as part of the next stage of large-scale testing and future implementation of the system as part of routine care.

Howell, Doris; Prestwich, Catherine; Laughlin, Emmy; Giga, Nasreen

2004-01-01

Palliative home care is an important component of the care system for patients at the end of life and case management is considered an essential element of the Canadian home care system. Case managers play a critical role in allocating resources, thus influencing the costs and the viability of palliative home care. Case management education programs focused on care coordination with specialty palliative care populations are nonexistent. An education program targeted at improving the knowledge and skills of case managers in allocating resources to palliative care populations was developed and pilot-tested in a metropolitan Canadian city home care program. Core curriculum was based on an initial learning needs assessment and used case-based problem solving to enhance case-management skills. An improvement in knowledge was noted on posttests and case managers described increased comfort and confidence in their role as case managers to this patient population. Home care organizations caring for palliative care populations must ensure case managers are prepared for case management roles with specialty populations if the home is to be rendered an appropriate and viable care setting for patients at the end of life.

The rules of good laboratory practice have always been observed in the laboratories of National Institute of Hygiene (NIH) and the reliability of the results has been carefully cared after when performing tests for clients. In 2003 the laboratories performing analyses related to food safety were designated as the national reference laboratories. This, added to the necessity of compliance with work standards and requirements of EU legislation and to the need of confirmation of competence by an independent organisation, led to a decision to seek accreditation of Polish Centre of Accreditation (PCA). The following stages of building and implementation of management system were presented: training, modifications of Institute's organisational structure, elaboration of management system's documentation, renovation and refurbishment of laboratory facilities, implementation of measuring and test equipment's supervision, internal audits and management review. The importance of earlier experiences and achievements with regard to validation of analytical methods and guarding of the quality of the results through organisation and participation in proficiency tests was highlighted. Current status of accreditation of testing procedures used in NIH laboratories that perform analyses in the field of chemistry, microbiology, radiobiology and medical diagnostic tests was presented.

To test the one year-post effect of an integrated diabetes care program that includes system changes, education, registry (clinical, metabolic and therapeutic indicators) and disease management (DIAPREM), implemented at primary care level, on care outcomes and costs. We randomly selected 15 physicians and 15 nurses from primary care units of La Matanza County to be trained (Intervention-IG) and another 15 physicians/nurses to use as controls (Control-CG). Each physician-nurse team controlled and followed up 10 patients with type 2 diabetes for one year; both groups use structured medical data registry. Patients in IG had quarterly clinical appointments whereas those in CG received traditional care. DIAPREM includes system changes (use of guidelines, programmed quarterly controls and yearly visits to the specialist) and education (physicians' and nurses' training courses). Statistical data analysis included parametric/nonparametric tests according to data distribution profile and Chi-squared test for proportions. Baseline data from both groups showed comparable values and 20-30% of them did not perform HbA1c and lipid profile measurements. Majority were obese, 59% had HbA1C ≥7%, 86% fasting blood glucose ≥100mg/dL, 45%, total cholesterol ≥200mg/dL, and 92% abnormal HDL- and LDL-cholesterol values. Similarly, micro and macroangiopathic complications had not been detected in the previous year. Most patients received oral antidiabetic agents (monotherapy), and one third was on insulin (mostly a single dose of an intermediate/long-acting formulation). Most people with hypertension received specific drug treatment but only half of them reached target values; dyslipidemia treatment showed similar data. Baseline data demonstrated the need of implementing an intervention to improve diabetes care and treatment outcomes. Copyright © 2016 Primary Care Diabetes Europe. Published by Elsevier Ltd.

Hierro, Luis A; Gómez-Álvarez, Rosario; Atienza, Pedro

2014-01-01

In studies on the redistributive, vertical, and horizontal effects of health care financing, the sum of the contributions calculated for each financial instrument does not equal the total effects. As a consequence, the final calculations tend to be overestimated or underestimated. The solution proposed here involves the adaptation of the Shapley value to achieve additive results for all the effects and reveals the relative contributions of different instruments to the change of whole-system equity. An understanding of this change would help policy makers attain equitable health care financing. We test the method with the public finance and private payments of health care systems in Denmark and the Netherlands. Copyright © 2013 John Wiley & Sons, Ltd.

Mutation Testing for Effective Verification of Digital Components of Physical Systems

2015-12-01

Digital components of modern physical systems are often designed applying circuitry solutions based on the field programmable gate array technology (FPGA). Such (embedded) digital components should be carefully tested. In this paper, an approach for the verification of digital physical system components based on mutation testing is proposed. The reference description of the behavior of a digital component in the hardware description language (HDL) is mutated by introducing into it the most probable errors and, unlike mutants in high-level programming languages, the corresponding test case is effectively derived based on a comparison of special scalable representations of the specification and the constructed mutant using various logic synthesis and verification systems.

We describe the development and evaluation of a secure Web-based system for the purpose of collaborative care called Loop. Loop assembles the team of care with the patient as an integral member of the team in a secure space. The objectives of this paper are to present the iterative design of the separate views for health care providers (HCPs) within each patient's secure space and examine patients', caregivers', and HCPs' perspectives on this separate view for HCP-only communication. The overall research program includes cycles of ethnography, prototyping, usability testing, and pilot testing. This paper describes the usability testing phase that directly informed development. A descriptive qualitative approach was used to analyze participant perspectives that emerged during usability testing. During usability testing, we sampled 89 participants from three user groups: 23 patients, 19 caregivers, and 47 HCPs. Almost all perspectives from the three user groups supported the need for an HCP-only communication view. In an earlier prototype, the visual presentation caused confusion among HCPs when reading and composing messages about whether a message was visible to the patient. Usability testing guided us to design a more deliberate distinction between posting in the Patient and Team view and the Health Care Provider Only view at the time of composing a message, which once posted is distinguished by an icon. The team made a decision to incorporate an HCP-only communication view based on findings during earlier phases of work. During usability testing we tested the separate communication views, and all groups supported this partition. We spent considerable effort designing the partition; however, preliminary findings from the next phase of evaluation, pilot testing, show that the Patient and Team communication is predominantly being used. This demonstrates the importance of a subsequent phase of the clinical trial of Loop to validate the concept and design.

Background Patient self-management interventions for smoking cessation are effective but underused. Health care providers do not routinely refer smokers to these interventions. Objective The objective of our study was to uncover barriers and facilitators to the use of an e-referral system that will be evaluated in a community-based randomized trial. The e-referral system will allow providers to refer smokers to an online smoking intervention during routine clinical care. Methods We devised a four-step development and pilot testing process: (1) system conceptualization using Delphi to identify key functionalities that would overcome barriers in provider referrals for smoking cessation, (2) Web system programming using agile software development and best programming practices with usability refinement using think-aloud testing, (3) implementation planning using the nominal group technique for the effective integration of the system into the workflow of practices, and (4) pilot testing to identify practice recruitment and system-use barriers in real-world settings. Results Our Delphi process (step 1) conceptualized three key e-referral functions: (1) Refer Your Smokers, allowing providers to e-refer patients at the point of care by entering their emails directly into the system, (2) practice reports, providing feedback regarding referrals and impact of smoking-cessation counseling, and (3) secure messaging, facilitating provider–patient communication. Usability testing (step 2) suggested the system was easy to use, but implementation planning (step 3) suggested several important approaches to encourage use (eg, proactive email cues to encourage practices to participate). Pilot testing (step 4) in 5 practices had limited success, with only 2 patients referred; we uncovered important recruitment and system-use barriers (eg, lack of study champion, training, and motivation, registration difficulties, and forgetting to refer). Conclusions Implementing a system to be used in a clinical setting is complex, as several issues can affect system use. In our ongoing large randomized trial, preliminary analysis with the first 50 practices using the system for 3 months demonstrated that our rigorous preimplementation evaluation helped us successfully identify and overcome these barriers before the main trial.

Background The global initiative ‘Treatment 2.0’ calls for expanding the evidence base of optimal HIV service delivery models to maximize HIV case detection and retention in care. However limited systematic assessment has been conducted in countries with concentrated HIV epidemic. We aimed to assess HIV service availability and service connectedness in Vietnam. Methods We developed a new analytical framework of the continuum of prevention and care (COPC). Using the framework, we examined HIV service delivery in Vietnam. Specifically, we analyzed HIV service availability including geographical distribution and decentralization and service connectedness across multiple services and dimensions. We then identified system-related strengths and constraints in improving HIV case detection and retention in care. This was accomplished by reviewing related published and unpublished documents including existing service delivery data. Results Identified strengths included: decentralized HIV outpatient clinics that offer comprehensive care at the district level particularly in high HIV burden provinces; functional chronic care management for antiretroviral treatment (ART) with the involvement of people living with HIV and the links to community- and home-based care; HIV testing and counseling integrated into tuberculosis and antenatal care services in districts supported by donor-funded projects, and extensive peer outreach networks that reduce barriers for the most-at-risk populations to access services. Constraints included: fragmented local coordination mechanisms for HIV-related health services; lack of systems to monitor the expansion of HIV outpatient clinics that offer comprehensive care; underdevelopment of pre-ART care; insufficient linkage from HIV testing and counseling to pre-ART care; inadequate access to HIV-related services in districts not supported by donor-funded projects particularly in middle and low burden provinces and in mountainous remote areas; and no systematic monitoring of referral services. Conclusions Our COPC analytical framework was instrumental in identifying system-related strengths and constraints that contribute to HIV case detection and retention in care. The national HIV program plans to strengthen provincial programming by re-defining various service linkages and accelerate the transition from project-based approach to integrated service delivery in line with the ‘Treatment 2.0’ initiative.

Clinical Decision Support Systems (CDSS) are tools that assist healthcare personnel in the decision-making process for patient care. Although CDSSs have been successfully deployed in the clinical setting to assist physicians, few CDSS have been targeted at professional nurses, the largest group of health providers. We present our experience in designing and testing a CDSS interface embedded within a nurse care planning and documentation tool. We developed four prototypes based on different CDSS feature designs, and tested them in simulated end-of-life patient handoff sessions with a group of 40 nurse clinicians. We show how our prototypes directed nurses towards an optimal care decision that was rarely performed in unassisted practice. We also discuss the effect of CDSS layout and interface navigation in a nurse's acceptance of suggested actions. These findings provide insights into effective nursing CDSS design that are generalizable to care scenarios different than end-of-life.

Soaring health care costs and a rapidly aging population, with multiple comorbidities, necessitates the development of innovative strategies to deliver high-quality, value-based care. The goal of this study is to evaluate the impact of a risk assessment system (CareSage) and targeted interventions on health care utilization. This is a two-arm randomized controlled trial recruiting 370 participants from a pool of high-risk patients receiving care at a home health agency. CareSage is a risk assessment system that utilizes both real-time data collected via a Personal Emergency Response Service and historical patient data collected from the electronic medical records. All patients will first be observed for 3 months (observation period) to allow the CareSage algorithm to calibrate based on patient data. During the next 6 months (intervention period), CareSage will use a predictive algorithm to classify patients in the intervention group as "high" or "low" risk for emergency transport every 30 days. All patients flagged as "high risk" by CareSage will receive nurse triage calls to assess their needs and personalized interventions including patient education, home visits, and tele-monitoring. The primary outcome is the number of 180-day emergency department visits. Secondary outcomes include the number of 90-day emergency department visits, total medical expenses, 180-day mortality rates, time to first readmission, total number of readmissions and avoidable readmissions, 30-, 90-, and 180-day readmission rates, as well as cost of intervention per patient. The two study groups will be compared using the Student t test (two-tailed) for normally distributed and Mann Whitney U test for skewed continuous variables, respectively. The chi-square test will be used for categorical variables. Time to event (readmission) and 180-day mortality between the two study groups will be compared by using the Kaplan-Meier survival plots and the log-rank test. Cox proportional hazard regression will be used to compute hazard ratio and compare outcomes between the two groups. We are actively enrolling participants and the study is expected to be completed by end of 2018; results are expected to be published in early 2019. Innovative solutions for identifying high-risk patients and personalizing interventions based on individual risk and needs may help facilitate the delivery of value-based care, improve long-term patient health outcomes and decrease health care costs.

Increasing efficacy of primary care-based counseling for diabetes prevention: rationale and design of the ADAPT (Avoiding Diabetes Thru Action Plan Targeting) trial.

PubMed

Mann, Devin M; Lin, Jenny J

2012-01-23

Studies have shown that lifestyle behavior changes are most effective to prevent onset of diabetes in high-risk patients. Primary care providers are charged with encouraging behavior change among their patients at risk for diabetes, yet the practice environment and training in primary care often do not support effective provider counseling. The goal of this study is to develop an electronic health record-embedded tool to facilitate shared patient-provider goal setting to promote behavioral change and prevent diabetes. The ADAPT (Avoiding Diabetes Thru Action Plan Targeting) trial leverages an innovative system that integrates evidence-based interventions for behavioral change with already-existing technology to enhance primary care providers' effectiveness to counsel about lifestyle behavior changes. Using principles of behavior change theory, the multidisciplinary design team utilized in-depth interviews and in vivo usability testing to produce a prototype diabetes prevention counseling system embedded in the electronic health record. The core element of the tool is a streamlined, shared goal-setting module within the electronic health record system. The team then conducted a series of innovative, "near-live" usability testing simulations to refine the tool and enhance workflow integration. The system also incorporates a pre-encounter survey to elicit patients' behavior-change goals to help tailor patient-provider goal setting during the clinical encounter and to encourage shared decision making. Lastly, the patients interact with a website that collects their longitudinal behavior data and allows them to visualize their progress over time and compare their progress with other study members. The finalized ADAPT system is now being piloted in a small randomized control trial of providers using the system with prediabetes patients over a six-month period. The ADAPT system combines the influential powers of shared goal setting and feedback, tailoring, modeling, contracting, reminders, and social comparisons to integrate evidence-based behavior-change principles into the electronic health record to maximize provider counseling efficacy during routine primary care clinical encounters. If successful, the ADAPT system may represent an adaptable and scalable technology-enabled behavior-change tool for all primary care providers. ClinicalTrials.gov Identifier NCT01473654.

Point-of-care diagnostics: market trends and growth drivers.

There is a significant demand for in vitro diagnostic (IVD) testing to move closer to the patient point-of-care diagnostics [POC]), whether in the hospital, physician's office, rapid clinic or the home, effectively cutting time to results and helping patients make better informed decisions about their health. To analyze the point-of-care market and its trends and growth drivers. In 2007, POC made up 30% of the IVD market and is expected to grow at 9% a year. Although the overall POC market is expected to grow steadily, infectious POC is now the most attractive segment. Availability of rapid random access molecular diagnostic system for critical care infectious diseases such as MRSA and sepsis in the near future is likely to be a significant driver of infectious POC post 2012. Owing to the extraordinary increase in the cost of care, healthcare delivery is moving to increasingly decentralized settings such as rapid clinics and the home, driven by point-of-care diagnostics that provide accurate and directional results. We are evolving from the analog testing world to the digital testing world, where diagnosis is exact and therapy can be administered and be predictably effective.

Developing a Web-Based Nursing Practice and Research Information Management System: A Pilot Study.

Many hospital information systems have been developed and implemented to collect clinical data from the bedside and have used the information to improve patient care. Because of a growing awareness that the use of clinical information improves quality of care and patient outcomes, measuring tools (electronic and paper based) have been developed, but most of them require multiple steps of data collection and analysis. This necessitated the development of a Web-based Nursing Practice and Research Information Management System that processes clinical nursing data to measure nurses' delivery of care and its impact on patient outcomes and provides useful information to clinicians, administrators, researchers, and policy makers at the point of care. This pilot study developed a computer algorithm based on a falls prevention protocol and programmed the prototype Web-based Nursing Practice and Research Information Management System. It successfully measured performance of nursing care delivered and its impact on patient outcomes successfully using clinical nursing data from the study site. Although Nursing Practice and Research Information Management System was tested with small data sets, results of study revealed that it has the potential to measure nurses' delivery of care and its impact on patient outcomes, while pinpointing components of nursing process in need of improvement.

Correlates of genetic monogamy in socially monogamous mammals: insights from Azara's owl monkeys

Understanding the evolution of mating systems, a central topic in evolutionary biology for more than 50 years, requires examining the genetic consequences of mating and the relationships between social systems and mating systems. Among pair-living mammals, where genetic monogamy is extremely rare, the extent of extra-group paternity rates has been associated with male participation in infant care, strength of the pair bond and length of the breeding season. This study evaluated the relationship between two of those factors and the genetic mating system of socially monogamous mammals, testing predictions that male care and strength of pair bond would be negatively correlated with rates of extra-pair paternity (EPP). Autosomal microsatellite analyses provide evidence for genetic monogamy in a pair-living primate with bi-parental care, the Azara's owl monkey (Aotus azarae). A phylogenetically corrected generalized least square analysis was used to relate male care and strength of the pair bond to their genetic mating system (i.e. proportions of EPP) in 15 socially monogamous mammalian species. The intensity of male care was correlated with EPP rates in mammals, while strength of pair bond failed to reach statistical significance. Our analyses show that, once social monogamy has evolved, paternal care, and potentially also close bonds, may facilitate the evolution of genetic monogamy. PMID:24648230

Supporting adolescent patient engagement in care is an important yet underexplored topic in consumer health informatics. Personal Health Records (PHRs) show potential, but designing PHR systems to accommodate both emerging adults and their parents is challenging. We conducted a mixed-methods study with teenage adolescent patients (ages 13-17) with cancer and blood disorders, and their parents, to investigate their experiences with My-Chart, a tethered PHR system. Through analyses of usage logs and independently-conducted surveys and interviews, we found that patients and parents both valued MyChart, but had different views about the role of the PHR for care communication and management, and different attitudes about its impact on the patient’s ability to manage care. Specific motivations for using MyChart included patient–parent coordination of care activities, communication around hospital encounters, and support for transitioning to adult care. Finally, some parents had concerns about certain diagnostic test results being made available to their children. PMID:28269859

Reform, change, and continuity in Finnish health care.

PubMed

Häkkinen, Unto; Lehto, Juhani

2005-01-01

This article describes some essential aspects of the Finnish political and governmental system and the evolution of the basic institutional elements of the health care system. We examine the developments that gave rise to a series of health care reforms and reform proposals in the late 1980s and early 1990s and relate them to changes in health care expenditure, structure, and performance. Finally, we discuss the relationship between policy changes, reforms, and health system changes and the strength of neo-institutional theory in explaining both continuity and change. Much of the change in Finnish health care can be explained by institutional path dependency. The tradition of strong but small local authorities and the lack of legitimate democratic regional authorities as well as the coexistence of a dominant Beveridge-style health system with a marginal Bismarckian element explain the specific path of Finnish health care reform. Public responsibility for health care has been decentralized to smaller local authorities (known as municipalities) more than in any other country. Even an exceptionally deep economic recession in the early 1990s did not lead to systems change; rather, the economic imperative was met by the traditional centralized policy pattern. Some of the developments of the 1990s are, however, difficult to explain by institutional theory. Thus, there is a need for testing alternative theories as well.

Patients undertaking long-term and chronic home hemodialysis (HHD) are subject to feelings of isolation and anxiety due to the absence of physical contact with their health care professionals and lack of feedback in regards to their dialysis treatments. Therefore, it is important for these patients to feel the "presence" of the health care professionals remotely while on hemodialysis at home for better compliance with the dialysis regime and to feel connected with health care professionals. This study presents an HHD system design for hemodialysis patients with features to enhance patient's perceived "copresence" with their health care professionals. Various mechanisms to enhance this perception were designed and implemented, including digital logbooks, emotion sharing, and feedback tools. The mechanism in our HHD system aims to address the limitations associated with existing self-monitoring tools for HHD patients. A field trial involving 3 nurses and 74 patients was conducted to test the pilot implementation of the copresence design in our HHD system. Mixed method research was conducted to evaluate the system, including surveys, interviews, and analysis of system data. Patients created 2757 entries of dialysis cases during the period of study. Altogether there were 492 entries submitted with "Very Happy" as the emotional status, 2167 entries with a "Happy" status, 56 entries with a "Neutral" status, 18 entries with an "Unhappy" status, and 24 entries with a "Very unhappy" status. Patients felt assured to share their emotions with health care professionals. Health care professionals were able to prioritize the review of the entries based on the emotional status and also felt assured to see patients' change in mood. There were 989 entries sent with short notes. Entries with negative emotions had a higher percentage of supplementary notes entered compared to the entries with positive and neutral emotions. The qualitative data further showed that the HHD system was able to improve patients' feelings of being connected with their health care professionals and thus enhance their self-care on HHD. The health care professionals felt better assured with patients' status with the use of the system and reported improved productivity and satisfaction with the copresence enhancement mechanism. The survey on the system usability indicated a high level of satisfaction among patients and nurses. The copresence enhancement design complements the conventional use of a digitized HHD logbook and will further benefit the design of future telehealth systems. ©Na Liu, Jinman Kim, Younhyun Jung, Adani Arisy, Mary Ann Nicdao, Mary Mikaheal, Tanya Baldacchino, Mohamed Khadra, Kamal Sud.

Within the mental health care system, there is an opportunity to improve patient safety and the overall quality of care by integrating clinical practice guidelines with the care planning process through the use of information technology. Electronic assessment tools such as the Resident Assessment Inventory - Mental Health (RAI-MH) are widely used to identify the health care needs and outcomes of clients. In this knowledge translation initiative, an electronic care planning tool was enhanced to include evidence-based clinical interventions from schizophrenia guidelines. This paper describes the development of a mental health decision support prototype, a field test by clinicians, and user experiences with the application.

Limited access to Chagas disease diagnosis and treatment is a major obstacle to reaching the 2020 World Health Organization milestones of delivering care to all infected and ill patients. Colombia has been identified as a health system in transition, reporting one of the highest levels of health insurance coverage in Latin America. We explore if and how this high level of coverage extends to those with Chagas disease, a traditionally marginalised population. Using a mixed methods approach, we calculate coverage for screening, diagnosis and treatment of Chagas. We then identify supply-side constraints both quantitatively and qualitatively. A review of official registries of tests and treatments for Chagas disease delivered between 2008 and 2014 is compared to estimates of infected people. Using the Flagship Framework, we explore barriers limiting access to care. Screening coverage is estimated at 1.2% of the population at risk. Aetiological treatment with either benznidazol or nifurtimox covered 0.3-0.4% of the infected population. Barriers to accessing screening, diagnosis and treatment are identified for each of the Flagship Framework's five dimensions of interest: financing, payment, regulation, organization and persuasion. The main challenges identified were: a lack of clarity in terms of financial responsibilities in a segmented health system, claims of limited resources for undertaking activities particularly in primary care, non-inclusion of confirmatory test(s) in the basic package of diagnosis and care, poor logistics in the distribution and supply chain of medicines, and lack of awareness of medical personnel. Very low screening coverage emerges as a key obstacle hindering access to care for Chagas disease. Findings suggest serious shortcomings in this health system for Chagas disease, despite the success of universal health insurance scale-up in Colombia. Whether these shortcomings exist in relation to other neglected tropical diseases needs investigating. We identify opportunities for improvement that can inform additional planned health reforms.

The-Optimal-Lymph-Flow health IT system (TOLF) is a patient-centered, web-and-mobile-based educational and behavioral health IT system focusing on safe, innovative, and pragmatic self-care strategies for lymphedema symptom management. The purpose of this study was to evaluate usability, feasibility, and acceptability of TOLF among the end-user of breast cancer survivors. Two types of usability testing were completed with 30 breast cancer survivors: heuristic evaluation and end-user testing. Each participant was asked to think aloud while completing a set of specified tasks designed to explicate and freely explore the system features. A heuristic evaluation checklist, the Perceived Ease of Use and Usefulness Questionnaire, and The Post Study System Usability Questionnaire were used to evaluate usability of the system. Open-ended questions were used to gather qualitative data. Quantitative data were analyzed using descriptive statistics and qualitative data were summarized thematically. Breast cancer survivors were very satisfied with the system: 90% (n = 27) rated the system having no usability problems; 10% (n = 3) noted minor cosmetic problems: spelling errors or text font size. The majority of participants 96.6% (n = 29) strongly agreed that the system was easy to use and effective in helping to learn about lymphedema, symptoms and self-care strategies. Themes from the qualitative data included empowerment, high quality information, loving avatar simulation videos, easy accessibility, and user-friendliness. This usability study provided evidence on breast cancer survivor's acceptance and highly positive evaluation of TOLF's usability as well as feasibility of using technologically-driven delivery model to enhance self-care strategies for lymphedema symptom management.

Integrating two distinct and complementary paradigms, science and engineering, may produce more effective outcomes for the implementation of evidence-based practices in health care settings. Science formalizes and tests innovations, whereas engineering customizes and optimizes how the innovation is applied tailoring to accommodate local conditions. Together they may accelerate the creation of an evidence-based healthcare system that works effectively in specific health care settings. We give examples of applying engineering methods for better quality, more efficient, and safer implementation of clinical practices, medical devices, and health services systems. A specific example was applying systems engineering design that orchestrated people, process, data, decision-making, and communication through a technology application to implement evidence-based depression care among low-income patients with diabetes. We recommend that leading journals recognize the fundamental role of engineering in implementation research, to improve understanding of design elements that create a better fit between program elements and local context.

2018-01-01

Background Our health care system fails to deliver necessary results, and incremental system improvements will not deliver needed change. Learning health systems (LHSs) are seen as a means to accelerate outcomes, improve care delivery, and further clinical research; yet, few such systems exist. We describe the process of codesigning, with all relevant stakeholders, an approach for creating a collaborative chronic care network (C3N), a peer-produced networked LHS. Objective The objective of this study was to report the methods used, with a diverse group of stakeholders, to translate the idea of a C3N to a set of actionable next steps. Methods The setting was ImproveCareNow, an improvement network for pediatric inflammatory bowel disease. In collaboration with patients and families, clinicians, researchers, social scientists, technologists, and designers, C3N leaders used a modified idealized design process to develop a design for a C3N. Results Over 100 people participated in the design process that resulted in (1) an overall concept design for the ImproveCareNow C3N, (2) a logic model for bringing about this system, and (3) 13 potential innovations likely to increase awareness and agency, make it easier to collect and share information, and to enhance collaboration that could be tested collectively to bring about the C3N. Conclusions We demonstrate methods that resulted in a design that has the potential to transform the chronic care system into an LHS. PMID:29472173

The transition from a pediatric to adult health care system is challenging for many youths with epilepsy and their families. Recently, the Ministry of Health and Long-Term Care of the Province of Ontario, Canada, created a transition working group (TWG) to develop recommendations for the transition process for patients with epilepsy in the Province of Ontario. Herein we present an executive summary of this work. The TWG was composed of a multidisciplinary group of pediatric and adult epileptologists, psychiatrists, and family doctors from academia and from the community; neurologists from the community; nurses and social workers from pediatric and adult epilepsy programs; adolescent medicine physician specialists; a team of physicians, nurses, and social workers dedicated to patients with complex care needs; a lawyer; an occupational therapist; representatives from community epilepsy agencies; patients with epilepsy; parents of patients with epilepsy and severe intellectual disability; and project managers. Three main areas were addressed: (1) Diagnosis and Management of Seizures; 2) Mental Health and Psychosocial Needs; and 3) Financial, Community, and Legal Supports. Although there are no systematic studies on the outcomes of transition programs, the impressions of the TWG are as follows. Teenagers at risk of poor transition should be identified early. The care coordination between pediatric and adult neurologists and other specialists should begin before the actual transfer. The transition period is the ideal time to rethink the diagnosis and repeat diagnostic testing where indicated (particularly genetic testing, which now can uncover more etiologies than when patients were initially evaluated many years ago). Some screening tests should be repeated after the move to the adult system. The seven steps proposed herein may facilitate transition, thereby promoting uninterrupted and adequate care for youth with epilepsy leaving the pediatric system.

Kumar, Saten

2013-06-01

This paper utilizes the systems generalized method of moments (GMM) [Arellano and Bover (1995) J Econometrics 68:29-51; Blundell and Bond (1998) J Econometrics 87:115-143], and panel Granger causality [Hurlin and Venet (2001) Granger Causality tests in panel data models with fixed coefficients. Mime'o, University Paris IX], to investigate the health care spending and gross domestic product (GDP) relationship for organisation for economic co-operation and development countries over the period 1960-2007. The system GMM estimates confirm that the contribution of real GDP to health spending is significant and positive. The panel Granger causality tests imply that a bi-directional causality exists between health spending and GDP. To this end, policies aimed at raising health spending will eventually improve the well-being of the population in the long run.

The channeling demonstration sought to substitute community care for nursing home care to reduce long-term care costs and improve the quality of life of elderly clients and the family members and friends who care for them. Two interventions were tested, each in five sites; both had comprehensive case management at their core. One model added a small amount of additional funding for direct community services to fill the gaps in the existing system; the other substantially expanded coverage of community services regardless of categorical eligibility under existing programs. The demonstration was evaluated using a randomized experimental design to test the effects of channeling on use of community care, nursing homes, hospitals, and informal caregiving, and on measures of the quality of life of clients and their informal caregivers. Data were obtained from interviews with clients and informal caregivers; service use and cost records came from Medicare, Medicaid, channeling, and providers; and death records for an 18-month follow-up period were examined.

Evaluation of predictive value of liver function tests (LFTs) for the detection of liver-related disease in primary care. A prospective observational study. 11 UK primary care practices. Patients (n=1290) with an abnormal eight-panel LFT (but no previously diagnosed liver disease). Patients were investigated by recording clinical features, and repeating LFTs, specific tests for individual liver diseases, and abdominal ultrasound scan. Patients were characterised as having: hepatocellular disease; biliary disease; tumours of the hepato-biliary system and none of the above. The relationship between LFT results and disease categories was evaluated by stepwise regression and logistic discrimination, with adjustment for demographic and clinical factors. True and False Positives generated by all possible LFT combinations were compared with a view towards optimising the choice of analytes in the routine LFT panel. Regression methods showed that alanine aminotransferase (ALT) was associated with hepatocellular disease (32 patients), while alkaline phosphatase (ALP) was associated with biliary disease (12 patients) and tumours of the hepatobiliary system (9 patients). A restricted panel of ALT and ALP was an efficient choice of analytes, comparing favourably with the complete panel of eight analytes, provided that 48 False Positives can be tolerated to obtain one additional True Positive. Repeating a complete panel in response to an abnormal reading is not the optimal strategy. The LFT panel can be restricted to ALT and ALP when the purpose of testing is to exclude liver disease in primary care.

In 2013, the American Society of Addiction Medicine (ASAM) approved its Standards of Care for the Addiction Specialist Physician. Subsequently, an ASAM Performance Measures Panel identified and prioritized the standards to be operationalized into performance measures. The goal of this study is to describe the process of operationalizing 3 of these standards into quality measures, and to present the initial measure specifications and results of pilot testing these measures in a large health care system. By presenting the process rather than just the end results, we hope to shed light on the measure development process to educate, and also to stimulate debate about the decisions that were made. Each measure was decomposed into major concepts. Then each concept was operationalized using commonly available administrative data sources. Alternative specifications examined and sensitivity analyses were conducted to inform decisions that balanced accuracy, clinical nuance, and simplicity. Using data from the US Veterans Health Administration (VHA), overall performance and variation in performance across 119 VHA facilities were calculated. Three measures were operationalized and pilot tested: pharmacotherapy for alcohol use disorder, pharmacotherapy for opioid use disorder, and timely follow-up after medically managed withdrawal (aka detoxification). Each measure was calculable with available data, and showed ample room for improvement (no ceiling effects) and wide facility-level variability. Next steps include conducting feasibility and pilot testing in other health care systems and other contexts such as standalone addiction treatment programs, and also to study the specification and predictive validity of these measures.

Personal Narratives of Genetic Testing: Expectations, Emotions, and Impact on Self and Family.

PubMed

Anderson, Emily E; Wasson, Katherine

2015-01-01

The stories in this volume shed light on the potential of narrative inquiry to fill gaps in knowledge, particularly given the mixed results of quantitative research on patient views of and experiences with genetic and genomic testing. Published studies investigate predictors of testing (particularly risk perceptions and worry); psychological and behavioral responses to testing; and potential impact on the health care system (e.g., when patients bring DTC genetic test results to their primary care provider). Interestingly, these themes did not dominate the narratives published in this issue. Rather, these narratives included consistent themes of expectations and looking for answers; complex emotions; areas of contradiction and conflict; and family impact. More narrative research on patient experiences with genetic testing may fill gaps in knowledge regarding how patients define the benefits of testing, changes in psychological and emotional reactions to test results over time, and the impact of testing on families.

Indigenous Australians experience disproportionately high prevalence of, and morbidity and mortality from diabetes. There is an urgent need to understand how Indigenous primary care systems are organised to deliver diabetes services to those most in need, to monitor the quality of diabetes care received by Indigenous people, and to improve systems for better diabetes care. The intervention featured two annual cycles of assessment, feedback workshops, action planning, and implementation of system changes in 12 Indigenous community health centres. Assessment included a structured review of health service systems and audit of clinical records. Main process of care measures included adherence to guideline-scheduled services and medication adjustment. Main patient outcome measures were HbA1c, blood pressure and total cholesterol levels. There was good engagement of health centre staff, with significant improvements in system development over the study period. Adherence to guideline-scheduled processes improved, including increases in 6 monthly testing of HbA1c from 41% to 74% (Risk ratio 1.93, 95% CI 1.71-2.10), 3 monthly checking of blood pressure from 63% to 76% (1.27, 1.13-1.37), annual testing of total cholesterol from 56% to 74% (1.36, 1.20-1.49), biennial eye checking by a ophthalmologist from 34% to 54% (1.68, 1.39-1.95), and 3 monthly feet checking from 20% to 58% (3.01, 2.52-3.47). Medication adjustment rates following identification of elevated HbA1c and blood pressure were low, increasing from 10% to 24%, and from 13% to 21% respectively at year 1 audit. However, improvements in medication adjustment were not maintained at the year 2 follow-up. Mean HbA1c value improved from 9.3 to 8.9% (mean difference -0.4%, 95% CI -0.7;-0.1), but there was no improvement in blood pressure or cholesterol control. This quality improvement (QI) intervention has proved to be highly acceptable in the Indigenous Australian primary care setting and has been associated with significant improvements in systems and processes of care and some intermediate outcomes. However, improvements appear to be limited by inadequate attention to abnormal clinical findings and medication management. Greater improvement in intermediate outcomes may be achieved by specifically addressing system barriers to therapy intensification through more effective engagement of medical staff in QI activities and/or greater use of nurse-practitioners.

Mobile work situations within home care of the elderly require immediate and ubiquitous access to patient-oriented data. The ongoing Swedish research project "Technical support for Mobile CloseCare" focuses on the development and evaluation of work-scenario oriented ICT support for enhanced home care of elderly citizens. The aim of the project is to provide a seamless and consistent information flow between different health care providers and to give intuitive access to information services for the elderly and their relatives. For that purpose, different independent software components are connected through a mobile communication platform. Flexible access to prioritized information for different users in different work situations will be given through a virtual health record. In order to obtain both usable and clinically relevant results, a user centered system development approach is followed. Evaluation of the project results will be based on usability tests and quasi-experimental studies on how system implementation influences quality of care and job- and life satisfaction for care providers, patients and relatives.

This study aimed to investigate the quality of life of women suffering from breast cancer undergoing chemotherapy in public and private health care systems. It is an observational, prospective study with 64 women suffering from breast cancer. Data was collected with two instruments: Quality of Life Questionnaire C30 and Breast Cancer Module BR23. By applying Mann Whitney and Friedman's statistical tests, p values < 0.05 were considered statistically significant. The significant results in public health care systems were: physical functions, pain symptom, body image, systemic effects and outlook for the future. In private health care systems, the results were sexual, social functions and body image. Women's quality of life was harmed by chemotherapy in both institutions. The quality of life of women has been harmed as a result of the chemotherapy treatment in both institutions, but in different domains, indicating the type of nursing care that should be provided according to the characteristics of each group.

2001-01-01

Personal Digital Assistants (PDAs) offer clinicians the ability to enter and manage critical information at the point of care. Although PDAs have always been designed to be intuitive and easy to use, recent advances in technology have made them even more accessible. The ability to link data on a PDA (client) to a central database (server) allows for near-unlimited potential in developing point of care applications and systems for patient data management. Although many stand-alone systems exist for PDAs, none are designed to work in an integrated client/server environment. This paper describes the design, software and hardware selection, and preliminary testing of a PDA based patient data and charting system for use in the University of Washington Neonatal Intensive Care Unit (NICU). This system will be the subject of a subsequent study to determine its impact on patient outcomes and clinician efficiency.

Electronic health records: postadoption physician satisfaction and continued use.

Wright, Edward; Marvel, Jon

2012-01-01

One goal of public-policy makers in general and health care managers in particular is the adoption and efficient utilization of electronic health record (EHR) systems throughout the health care industry. Consequently, this investigation focused on the effects of known antecedents of technology adoption on physician satisfaction with EHR technology and the continued use of such systems. The American Academy of Family Physicians provided support in the survey of 453 physicians regarding their satisfaction with their EHR use experience. A conceptual model merging technology adoption and computer user satisfaction models was tested using structural equation modeling. Results indicate that effort expectancy (ease of use) has the most substantive effect on physician satisfaction and the continued use of EHR systems. As such, health care managers should be especially sensitive to the user and computer interface of prospective EHR systems to avoid costly and disruptive system selection mistakes.

To test for an association between quality of care and patient choice to obtain care outside an integrated healthcare delivery system. We used administrative data to define dual-system use (Veterans Health Administration (VHA) and Medicare) in 1999 for VHA users with diabetes over 65 years old. Quality of diabetes care was determined by the last hemoglobin A1c (HA1c) value in 2000. The distance to nearest VHA facility minus the distance to nearest non-federal hospital was the instrumental variable in a two-part regression model which controlled for observed and unobserved factors. In 1999, 57.4% of subjects received care from both VHA and Medicare providers; their mean proportion of visits to Medicare providers was 0.41 (median 0.38). After controlling for observed and unobserved factors, higher proportions of Medicare visits were significantly associated with higher HA1c values; a 40% increase in the proportion of Medicare visits by those who did not use Medicare was associated with a 0.23% point increase in HA1c value. Dual-system use was associated with higher HA1c values, suggesting that veterans who chose to receive care outside the integrated VHA may have worse intermediate clinical outcomes than those who received care exclusively within the system.

Evidence-based pharmacological and behavioral interventions are often underutilized or inaccessible to persons with multiple sclerosis (MS) who have chronic pain and/or depression. Collaborative care is an evidence-based patient-centered, integrated, system-level approach to improving the quality and outcomes of depression care. We describe the development of and randomized controlled trial testing a novel intervention, MS Care, which uses a collaborative care model to improve the care of depression and chronic pain in a MS specialty care setting. We describe a 16-week randomized controlled trial comparing the MS Care collaborative care intervention to usual care in an outpatient MS specialty center. Eligible participants with chronic pain of at least moderate intensity (≥3/10) and/or major depressive disorder are randomly assigned to MS Care or usual care. MS Care utilizes a care manager to implement and coordinate guideline-based medical and behavioral treatments with the patient, clinic providers, and pain/depression treatment experts. We will compare outcomes at post-treatment and 6-month follow up. We hypothesize that participants randomly assigned to MS Care will demonstrate significantly greater control of both pain and depression at post-treatment (primary endpoint) relative to those assigned to usual care. Secondary analyses will examine quality of care, patient satisfaction, adherence to MS care, and quality of life. Study findings will aid patients, clinicians, healthcare system leaders, and policy makers in making decisions about effective care for pain and depression in MS healthcare systems.

Testing plays a vital role in primary care. Failures in the process are common and can be harmful. As the great 19th century microbiologist Louis Pasteur put it "chance favors only the prepared mind." Our objective is to prepare minds in primary care practices to improve safety in the testing process. Various principles from safety science can be applied. A prospective methodology that uses an anonymous practice survey based on concepts from failure modes and effects analysis is proposed. Responses are used to rank perceived hazards in the testing process, leading to prioritization of areas for intervention. Secondary data analysis (using data from a study of medication safety) was used to explore the value of this approach in the context of assessing the testing process. At 3 primary care practice sites, a total of 61 staff members completed 4 survey items examining the testing process. Comparison across practices shows that each has a distinct profile of hazards, which would lead each on a different path toward improvement. The proposed approach treats each practice as a unique complex adaptive system aiming to help it thrive by inculcating trust, mutual respect, and collaboration. Implications for patient safety research and practice are discussed.

(1) To pilot 'we DECide' in terms of influence on advance care planning policy and practice in nursing home dementia care units. (2) To investigate barriers and facilitators for implementing 'we DECide'. This was a pre-test-post-test study in 18 nursing homes. Measurements included: compliance with best practice of advance care planning policy (ACP-audit); advance care planning practice (ACP criteria: degree to which advance care planning was discussed, and OPTION scale: degree of involvement of residents and families in conversations). Advance care planning policy was significantly more compliant with best practice after 'we DECide'; policy in the control group was not. Advance care planning was not discussed more frequently, nor were residents and families involved to a higher degree in conversations after 'we DECide'. Barriers to realizing advance care planning included staff's limited responsibilities; facilitators included support by management staff, and involvement of the whole organization. 'We DECide' had a positive influence on advance care planning policy. Daily practice, however, did not change. Future studies should pay more attention to long-term implementation strategies. Long-term implementation of advance care planning requires involvement of the whole organization and a continuing support system for health care professionals. Copyright © 2016 Elsevier Ireland Ltd.

Background 'Cognitive Behavioral Analysis System of Psychotherapy' (CBASP) is a form of psychotherapy specifically developed for patients with chronic depression. In a study in the U.S., remarkable favorable effects of CBASP have been demonstrated. However, no other studies have as yet replicated these findings and CBASP has not been tested outside the United States. This protocol describes a randomized controlled trial on the effectiveness of CBASP in the Netherlands. Methods/Design The purpose of the present paper is to report the study protocol of a multisite randomized controlled trial testing the effectiveness of 'Cognitive Behavioral Analysis System of Psychotherapy' (CBASP) for chronic depression in the Netherlands. In this study, CBASP in combination with medication, will be tested versus usual secondary care in combination with medication. The aim is to recruit 160 patients from three mental health care organizations. Depressive symptoms will be assessed at baseline, after 8 weeks, 16 weeks, 32 weeks and 52 weeks, using the 28-item Inventory for Depressive Symptomatology (IDS). Effect modification by co morbid anxiety, alcohol consumption, general and social functioning and working alliance will be tested. GEE analyses of covariance, controlling for baseline value and center will be used to estimate the overall treatment effectiveness (difference in IDS score) at post-treatment and follow up. The primary analysis will be by 'intention to treat' using double sided tests. An economic analysis will compare the two groups in terms of mean costs and cost-effectiveness from a societal perspective. Discussion The study will provide an answer to the question whether the favorable effects of CBASP can be replicated outside the US. Trial Registration The Dutch Cochrane Center, NTR1090.

This paper presents the sensor network infrastructure for a home care system that allows long-term monitoring of physiological data and everyday activities. The aim of the proposed system is to allow the elderly to live longer in their home without compromising safety and ensuring the detection of health problems. The system offers the possibility of a virtual visit via a teleoperated robot. During the visit, physiological data and activities occurring during a period of time can be discussed. These data are collected from physiological sensors (e.g., temperature, blood pressure, glucose) and environmental sensors (e.g., motion, bed/chair occupancy, electrical usage). The system can also give alarms if sudden problems occur, like a fall, and warnings based on more long-term trends, such as the deterioration of health being detected. It has been implemented and tested in a test environment and has been deployed in six real homes for a year-long evaluation. The key contribution of the paper is the presentation of an implemented system for ambient assisted living (AAL) tested in a real environment, combining the acquisition of sensor data, a flexible and adaptable middleware compliant with the OSGistandard and a context recognition application. The system has been developed in a European project called GiraffPlus. PMID:24573309

Community-based primary mental health care is recommended in low and middle-income countries. The Brazilian Health System has been restructuring primary care by expanding its Family Health Strategy. Due to mental health problems, psychosocial vulnerability and accessibility, Matrix Support teams are being set up to broaden the professional scope of primary care. This paper aims to analyse the perceptions of health professionals and managers about the integration of primary care and mental health. In this mixed-method study 18 health managers and 24 professionals were interviewed from different primary and mental health care services in Rio de Janeiro. A semi-structured survey was conducted with 185 closed questions ranging from 1 to 5 and one open-ended question, to evaluate: access, gateway, trust, family focus, primary mental health interventions, mental health records, mental health problems, team collaboration, integration with community resources and primary mental health education. Two comparisons were made: health managers and professionals' (Mann-Whitney non-parametric test) and health managers' perceptions (Kruskall-Wallis non parametric-test) in 4 service designs (General Traditional Outpatients, Mental Health Specialised Outpatients, Psychosocial Community Centre and Family Health Strategy)(SPSS version 17.0). Qualitative data were subjected to Framework Analysis. Firstly, health managers and professionals' perceptions converged in all components, except the health record system. Secondly, managers' perceptions in traditional services contrasted with managers' perceptions in community-based services in components such as mental health interventions and team collaboration, and converged in gateway, trust, record system and primary mental health education. Qualitative data revealed an acceptance of mental health and primary care integration, but a lack of communication between institutions. The Mixed Method demonstrated that interviewees consider mental health and primary care integration as a requirement of the system, while their perceptions and the model of work produced by the institutional culture are inextricably linked. There is a gap between health managers' and professionals' understanding of community-based primary mental health care. The integration of different processes of work entails both rethinking workforce actions and institutional support to help make changes.

Do closed-system hospitals shift care under case payment? Early experiences comparing five surgeries in Taiwan.

Recently, Japan, Korea, and Taiwan have adopted prospective payment systems (PPS) for healthcare. Experiences of the United States Medicare show that PPS reduces length of stay but creates incentives to shift care from regulated to un-regulated settings. In this study we investigated whether closed-system hospitals in Taiwan responded to case payment (CP) - one type of PPS, and if so, how this was managed. Data were derived from three Taiwanese hospitals for five different surgical procedures (N = 22,327). The study period covered from October 1996 through August 1999, with CP commencing on October 1, 1997. Important dependent variables included inpatient medical claims, outpatient medical claims, and number of outpatient visits. Outpatient utilization from the period four weeks prior to admission and four weeks following discharge were merged for each patient. Ordinary Least Square (OLS) and Poisson regression were used to test the study's shifting hypotheses, controlling for gender, age, patient diagnoses, and institution attended. Length of hospital stay, amount of inpatient claims, and inpatient x-ray and lab-test claims were significantly reduced after CP. Corresponding OLS coefficients for the second year of implementation were, respectively, -.86, -.06, -.15, and -.04 (p < 0.01). Significant forward shifting of outpatient care, (79%), was found during the second year of CP. Despite the care-shifting effects noted herein, the average per-capita total claims reduced by 12%. Significant institutional effects were associated with the pattern of care-shifting. Our results indicate that CP reduced total claims for the selected surgical procedures, even under evident forward care-shifting.

The availability of pharmacogenomic data of individual patients can significantly improve physicians' prescribing behavior, lead to a reduced incidence of adverse drug events and an improvement of effectiveness of treatment. The Medicine Safety Code (MSC) initiative is an effort to improve the ability of clinicians and patients to share pharmacogenomic data and to use it at the point of care. The MSC is a standardized two-dimensional barcode that captures individual pharmacogenomic data. The system is backed by a web service that allows the decoding and interpretation of anonymous MSCs without requiring the installation of dedicated software. The system is based on a curated, ontology-based knowledge base representing pharmacogenomic definitions and clinical guidelines. The MSC system performed well in preliminary tests. To evaluate the system in realistic health care settings and to translate it into practical applications, the future participation of stakeholders in clinical institutions, researchers, pharmaceutical companies, genetic testing providers, health IT companies and health insurance organizations will be essential.

Unraveling care integration: Assessing its dimensions and antecedents in the Italian Health System.

PubMed

Calciolari, Stefano; Ilinca, Stefania

2016-01-01

In recent decades, consensus has grown on the need to organize health systems around the concept of care integration to better confront the challenges associated with demographic trends and financial sustainability. However, care integration remains an imprecise umbrella term in both the academic and policy arenas. In addition, little substantive knowledge exists on the success factors for integration initiatives. We propose a composite measure of care integration and a conceptual framework suggesting its relationships with three types of antecedents: contextual, cultural, and organizational factors. Our framework was tested using data from the Italian National Health System (NHS). We administered an ad-hoc questionnaire to all Italian local health units (LHUs), with a 60.4% response rate, and used structural equation modeling to assess the relationships between the relevant latent constructs. The results validated our measure of care integration and supported the hypothesized relationships. In particular, integration was found to be fostered by results-oriented institutional settings, a professional culture conducive to inclusiveness and shared goals, and organizational arrangements promoting clear expectations among providers. Thus, integration improves care and mediates the effects of specific operating means on care enhancement. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Medication therapy management and condition care services in a community-based employer setting.

A program in which health-system pharmacists and pharmacy technicians provide medication therapy management (MTM), wellness, and condition care (disease management) services under contract with local businesses is described. The health-system pharmacy department's Center for Medication Management contracts directly with company benefits departments for defined services to participating employees. The services include an initial wellness and MTM session and, for certain patients identified during the initial session, ongoing condition care. The initial appointment includes a medication history, point-of-care testing for serum lipids and glucose, body composition analysis, and completion of a health risk assessment. The pharmacist conducts a structured MTM session, reviews the patient's test results and risk factors, provides health education, discusses opportunities for cost savings, and documents all activities on the patient's medication action plan. Eligibility for the condition care program is based on a diagnosis of diabetes, hypertension, asthma, heart failure, or hyperlipidemia or elevation of lipid or glucose levels. Findings are summarized for employers after the initial wellness screening and at six-month intervals. Patients receiving condition care sign a customized contract, establish goals, attend up to four MTM sessions per year, and track their information on a website; employers may offer incentives for participation. When pharmacists recommend adjustments to therapy or cost-saving changes, it is up to patients to discuss these with their physician. A survey completed by each patient after the initial wellness session has indicated high satisfaction. Direct cost savings related to medication changes have averaged $253 per patient per year. Total cost savings to companies in the first year of the program averaged $1011 per patient. For the health system, the program has been financially sustainable. Key laboratory values indicate positive clinical outcomes. A business model in which health-system pharmacists provide MTM and condition care services for company employees has demonstrated successful outcomes in terms of patient satisfaction, cost savings, and clinical benefits.

To investigate the records of ambulatory medical care from patients predating the diagnosis of systemic lupus erythematosus (SLE) using nationwide, population-based claims data. The frequencies and costs of ambulatory medical care utilization in 337 newly-diagnosed SLE cases between 2004 and 2010, identified from Taiwan's National Health Insurance Research Database, were compared with 1,348 controls who were frequency matched for sex, age, and the catastrophic illness certificate application year of the cases. Patients with SLE had a median frequency of ambulatory medical care utilization compared with controls one year prior to the index date (22 vs. 2, P<0.001). The differences were significant throughout all eight annual periods. Similarly, the inflation-adjusted costs of ambulatory medical care utilization in patients with SLE increased annually over the study period, from a median of US$18 eight years prior to the index date to US$680 one year prior to the index date. Diseases of the respiratory system (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 460-519), digestive system (ICD-9-CM codes 520-579), musculoskeletal system and connective tissue (ICD-9-CM codes 710-739, excluding 710.0), and skin and subcutaneous tissue (ICD-9-CM codes 680-709) were the top four common causes of visits in the 0.5 to 2 year period preceding the index date and percentages of SLE patients suffered from these disorders increased progressively over the study period. Only 56.4% of the patients with SLE had consulted a rheumatologist and most of the serology tests were done within one year predating the index date. Increased frequencies and costs of ambulatory care utilization among Taiwanese patients with SLE occurred several years predating their definitive SLE diagnosis. When multisystemic disorders are presented in young female patients, the possibility of SLE should be considered and screened with tools such as the antinuclear antibody test.

Paternal care and litter size coevolution in mammals.

Biparental care of offspring occurs in diverse mammalian genera and is particularly common among species with socially monogamous mating systems. Despite numerous well-documented examples, however, the evolutionary causes and consequences of paternal care in mammals are not well understood. Here, we investigate the evolution of paternal care in relation to offspring production. Using comparative analyses to test for evidence of evolutionary associations between male care and life-history traits, we explore if biparental care is likely to have evolved because of the importance of male care to offspring survival, or if evolutionary increases in offspring production are likely to result from the evolution of biparental care. Overall, we find no evidence that paternal care has evolved in response to benefits of supporting females to rear particularly costly large offspring or litters. Rather, our findings suggest that increases in offspring production are more likely to follow the evolution of paternal care, specifically where males contribute depreciable investment such as provisioning young. Through coevolution with litter size, we conclude that paternal care in mammals is likely to play an important role in stabilizing monogamous mating systems and could ultimately promote the evolution of complex social behaviours. © 2016 The Authors.

As efforts are accelerated to improve the overall capability and performance of wind electric systems, increased attention to variable speed configurations has developed. A number of potentially viable configurations have emerged. Various attributes of variable speed systems need to be carefully tested to evaluate their performance from the utility points of view. With this purpose, the NASA experimental variable speed constant frequency (VSCF) system has been tested. In order to determine the usefulness of these systems in utility applications, tests are required to resolve issues fundamental to electric utility systems. Legitimate questions exist regarding how variable speed generators will influence the performance of electric utility systems; therefore, tests from a utility perspective, have been performed on the VSCF system and an induction generator at an operating power level of 30 kW on a system rated at 200 kVA and 0.8 power factor.

A Colorimetric Enzyme-Linked Immunosorbent Assay (ELISA) Detection Platform for a Point-of-Care Dengue Detection System on a Lab-on-Compact-Disc.

The enzyme-linked Immunosorbent Assay (ELISA) is the gold standard clinical diagnostic tool for the detection and quantification of protein biomarkers. However, conventional ELISA tests have drawbacks in their requirement of time, expensive equipment and expertise for operation. Hence, for the purpose of rapid, high throughput screening and point-of-care diagnosis, researchers are miniaturizing sandwich ELISA procedures on Lab-on-a-Chip and Lab-on-Compact Disc (LOCD) platforms. This paper presents a novel integrated device to detect and interpret the ELISA test results on a LOCD platform. The system applies absorption spectrophotometry to measure the absorbance (optical density) of the sample using a monochromatic light source and optical sensor. The device performs automated analysis of the results and presents absorbance values and diagnostic test results via a graphical display or via Bluetooth to a smartphone platform which also acts as controller of the device. The efficacy of the device was evaluated by performing dengue antibody IgG ELISA on 64 hospitalized patients suspected of dengue. The results demonstrate high accuracy of the device, with 95% sensitivity and 100% specificity in detection when compared with gold standard commercial ELISA microplate readers. This sensor platform represents a significant step towards establishing ELISA as a rapid, inexpensive and automatic testing method for the purpose of point-of-care-testing (POCT) in resource-limited settings.

Fura, Louise A; Wisser, Kathleen Z

Nurse educators are charged to develop and evaluate curricula on systems thinking to prepare future nurses to provide safe nursing care. The goal of this pilot study was to design and evaluate a four-hour educational strategy that prepares future professional nurses to use systems thinking approaches in the delivery of safe patient care. This study exposed prelicensure baccalaureate nursing students to systems thinking principles, which included didactic and experiential activities. A descriptive design was used to determine the effect of an on-campus educational strategy. A paired samples t-test revealed statistical significance from pretest to posttest.

Screening for cervical, breast and colon cancers, and elevations of cholesterol and glucose, reduces premature cause-specific mortality from these cancers and circulatory diseases. Despite primary care reforms and incentives, and promotion of cancer-screening programs among individuals, participation is suboptimal. We aimed to examine participation as of Dec. 31, 2011, by factors of deprivation, demographics and primary care at the small-area level. From health care administrative databases, we identified people eligible for each screening test, and their participation, in each dissemination area (referred to as small areas, n = 18 950) in Ontario. We calculated rates for each test among small areas (overall and stratified by demographic, socioeconomic and primary care descriptors) and stratified by sex for all tests combined. We loaded all data into a geographic information system. Funnel plots were generated showing the percentage of eligible people who completed screening for all tests by small area, stratified by sex. Overall and stratified screening prevalence ratios were calculated among small areas. Among small areas, the mean and SD for participation in all tests combined was 31.6% (SD 11.0%) for women and 41.2% (SD 12.0%) for men. Screening prevalence among small areas, for each test and for all tests combined, overall and stratified by sex, declined with decreasing percentage with high school completion, decreasing socioeconomic quintile, and decreasing percentage with an identifiable primary care physician. Our results show that the rate of participation in all eligible screening tests among small areas is much lower than the rate of participation in any one particular test. This finding has implications for the design and implementation of strategies to improve rates of screening.

Use of interferon-gamma release assays in a health care worker screening program: experience from a tertiary care centre in the United States.

Interferon-gamma release assays including the QuantiFERON-TB Gold In-Tube test (QFT-GIT [Cellestis Ltd, Australia]) may be used in place of the tuberculin skin test (TST) in surveillance programs for Mycobacterium tuberculosis infection control. However, data on performance and practicality of the QFT-GIT in such programs for health care workers (HCWs) are limited. To assess the performance, practicality and reversion rate of the QFT-GIT among HCWs at a tertiary health care institution in the United States. Retrospective chart review of HCWs at Central Arkansas Veterans Healthcare System (Arkansas, USA) who underwent QFT-GIT testing as a part of their employee screening between November 1, 2008 and October 31, 2009. QFT-GIT was used to screen 3290 HCWs. The initial QFT-GIT was interpreted as positive for 129 (3.9%) HCWs, negative for 3155 (95.9%) and indeterminate for six (0.2%). Testing with QFT-GIT was repeated in 45 HCWs who had positive results on the initial test. The QFT-GIT reverted to negative in 18 (40.0%) HCWs, all of whom had negative TST status and initial interferon-gamma values of 0.35 IU⁄mL to 2.0 IU⁄mL. The QFT-GIT test is feasible in large health care setting as an alternative to TST for M tuberculosis infection screening in HCWs but is not free from challenges. The major concerns are the high number of positive test results and high reversion rates on repeat testing, illustrating poor short-term reproducibility of positive QFT-GIT test results. These results suggest adopting a borderline zone between interferon-gamma values of 0.35 IU⁄mL to 2.0 IU⁄mL, and cautious clinical interpretation of values in this range.

Impact of a fixed price system on the supply of institutional long-term care: a comparative study of Japanese and German metropolitan areas.

The need for institutional long-term care is increasing as the population ages and the pool of informal care givers declines. Care services are often limited when funding is controlled publicly. Fees for Japanese institutional care are publicly fixed and supply is short, particularly in expensive metropolitan areas. Those insured by universal long-term care insurance (LTCI) are faced with geographically inequitable access. The aim of this study was to examine the impact of a fixed price system on the supply of institutional care in terms of equity. The data were derived from official statistics sources in both Japan and Germany, and a self-administered questionnaire was used in Japan in 2011. Cross-sectional multiple regression analyses were used to examine factors affecting bed supply of institutional/residential care in fixed price and free prices systems in Tokyo (Japan), and an individually-bargained price system in North Rhine-Westphalia (Germany). Variables relating to costs and needs were used to test hypotheses of cost-dependency and need-orientation of bed supply in each price system. Analyses were conducted using data both before and after the introduction of LTCI, and the results of each system were qualitatively compared. Total supply of institutional care in Tokyo under fixed pricing was found to be cost-dependent regarding capital costs and scale economies, and negatively related to need. These relationships have however weakened in recent years, possibly caused by political interventions under LTCI. Supply of residential care in Tokyo under free pricing was need-oriented and cost-dependent only regarding scale economies. Supply in North Rhine-Westphalia under individually bargained pricing was cost-independent and not negatively related to need. Findings suggest that publicly funded fixed prices have a negative impact on geographically equitable supply of institutional care. The contrasting results of the non-fixed-price systems for Japanese residential care and German institutional care provide further theoretical supports for this and indicate possible solutions against inequitable supply.

Background In 2005, the World Health Conference called for all nations to move toward universal health coverage, which is defined as “access to adequate health care for all at an affordable price”. Despite this, an estimated 90% of Somalia’s largely impoverished population use private health care. Therefore, considering that the private health care system is the dominant health care system in Mogadishu, Somalia, exploring the accessibility to, as well as people’s trust in, the private sector is essential to help contribute an equitable and affordable health care system in the country. Methods A qualitative study using unstructured interviews was conducted in Mogadishu from August to November of 2016. A purposive sampling approach was used to recruit 23 participants, including seven medical doctors who own private health centers, eight patients, five medical students and three senior officials who work for the Ministry of Health. Data were analyzed using a thematic analysis. Results Our findings show that the private health care system in Mogadishu is not only unregulated but also expensive, with the cost of health care often unaffordable for the majority of the country’s citizens. There is evidence of prescription of inappropriate treatment, tendency to conduct unnecessary laboratory tests, excessive use of higher diagnostic technologies and overcharging – including the widespread practice of further appointments for follow-up – which inflates the costs. The study also found poor patient–provider relationship and widespread distrust of the private health care system. Conclusion The study findings underline the need for the Somali government to develop regulatory mechanisms and guidelines with the potential to guide the private health care sector to provide equitable and affordable health care to people in Mogadishu. The doctor–patient relationship has been – and remains – a keystone of care; thus, there is an urgent need for guidelines for private health care providers to treat their patients with dignity and respect. The education system, particularly the syllabus used by medical faculties, should be reviewed and improved to provide medical students with necessary knowledge, skills and attitudes to maintain patient dignity and rights.

The purpose of this study was to establish the psychometric properties of the new 16-item leadership environment scale. The leadership environment scale was based on complexity science concepts relevant to complex adaptive health care systems. A workforce survey of direct-care nurses was conducted (n = 1,443) in Oregon. Confirmatory factor analysis, exploratory factor analysis, concordant validity test and reliability tests were conducted to establish the structure and internal consistency of the leadership environment scale. Confirmatory factor analysis indices approached acceptable thresholds of fit with a single factor solution. Exploratory factor analysis showed improved fit with a two-factor model solution; the factors were labelled 'influencing relationships' and 'interdependent system supports'. Moderate to strong convergent validity was observed between the leadership environment scale/subscales and both the nursing workforce index and the safety organising scale. Reliability of the leadership environment scale and subscales was strong, with all alphas ≥.85. The leadership environment scale is structurally sound and reliable. Nursing management can employ adaptive complexity leadership attributes, measure their influence on the leadership environment, subsequently modify system supports and relationships and improve the quality of health care systems. The leadership environment scale is an innovative fit to complex adaptive systems and how nurses act as leaders within these systems. © 2017 John Wiley & Sons Ltd.

Infrared imaging-based combat casualty care system

A Small Business Innovative Research (SBIR) contract was recently awarded to a start up company for the development of an infrared (IR) image based combat casualty care system. The company, Medical Thermal Diagnostics, or MTD, is developing a light weight, hands free, energy efficient uncooled IR imaging system based upon a Texas Instruments design which will allow emergency medical treatment of wounded soldiers in complete darkness without any type of light enhancement equipment. The principal investigator for this effort, Dr. Gene Luther, DVM, Ph.D., Professor Emeritus, LSU School of Veterinary Medicine, will conduct the development and testing of this system with support from Thermalscan, Inc., a nondestructive testing company experienced in IR thermography applications. Initial research has been done with surgery on a cat for feasibility of the concept as well as forensic research on pigs as a close representation of human physiology to determine time of death. Further such studies will be done later as well as trauma studies. IR images of trauma injuries will be acquired by imaging emergency room patients to create an archive of emergency medical situations seen with an infrared imaging camera. This archived data will then be used to develop training material for medical personnel using the system. This system has potential beyond military applications. Firefighters and emergency medical technicians could directly benefit from the capability to triage and administer medical care to trauma victims in low or no light conditions.

Diverse stakeholders—clinicians, researchers, business leaders, policy makers, and the public—have good reason to believe that the effective use of electronic health care records (EHRs) is essential to meaningful advances in health care quality and patient safety. However, several reports have documented the potential of EHRs to contribute to health care system flaws and patient harm. As organizations (including small hospitals and physician practices) with limited resources for care-process transformation, human-factors engineering, software safety, and project management begin to use EHRs, the chance of EHR-associated harm may increase. The authors propose a coordinated set of steps to advance the practice and theory of safe EHR design, implementation, and continuous improvement. These include setting EHR implementation in the context of health care process improvement, building safety into the specification and design of EHRs, safety testing and reporting, and rapid communication of EHR-related safety flaws and incidents.

The goal of this paper is to describe some benefits and possible cost consequences of computer based access to specialised health care information. A before-after activity analysis regarding 20 diabetic patients' clinical appointments was performed in a Health Centre in Satakunta region in Finland. Cost data, an interview, time-and-motion studies, and flow charts based on modelling were applied. Access to up-to-date diagnostic information reduced redundant clinical re-appointments, repeated tests, and mail orders for missing data. Timely access to diagnostic information brought about several benefits regarding workflow, patient care, and disease management. These benefits resulted in theoretical net cost savings. The study results indicated that Regional Information Systems may be useful tools to support performance and improve efficiency. However, further studies are required in order to verify how the monetary savings would impact the performance of Health Care Units.

Donabedian felt the 3 major components affecting quality were process, structure, and outcome. Later investigators often substitute the word "structure" for a broader concept called the "work system." One component of the latter is the people involved, and for diagnosis, this often is best done with a diagnostic team. The work system in diagnosis has many obstacles to achieve optimum performance. There are also important problems with how tests are ordered and interpreted and clinical reasoning and biases.

Background/Aims Despite robust evidence to guide clinical care, most patients with diabetes do not meet all goals of risk factor control. Improved patient-provider communication during time-limited primary care visits may represent one strategy for improving diabetes care. Methods We designed a controlled, cluster-randomized, multi-site intervention (Pre-Visit Prioritization for Complex Patients with Diabetes) that enables patients with poorly controlled type 2 diabetes to identify their top priorities prior to a scheduled visit and sends these priorities to the primary care physician progress note in the electronic medical record. In this paper, we describe strategies to address challenges to implementing our health IT-based intervention study within a large health care system. Results This study is being conducted in 30 primary care practices within a large integrated care delivery system in Northern California. Over a 12-week period (3/1/2015 – 6/6/2015), 146 primary care physicians consented to enroll in the study (90.1%) and approved contact with 2496 of their patients (97.6%). Implementation challenges included: (1) Navigating research vs. quality improvement requirements; (2) Addressing informed consent considerations; and (3) Introducing a new clinical tool into a highly time-constrained workflow. Strategies for successfully initiating this study included engagement with institutional leaders, Institutional Review Board members, and clinical stakeholders at multiple stages both before and after notice of Federal funding; flexibility by the research team in study design; and strong support from institutional leadership for “self-learning health system” research. Conclusions By paying careful attention to identifying and collaborating with a wide range of key clinical stakeholders, we have shown that researchers embedded within a learning care system can successfully apply rigorous clinical trial methods to test new care innovations.

Objective To characterize prenatal and delivery care in an urban African setting. Methods The Zambia Electronic Perinatal Record System (ZEPRS) was implemented to record demographic characteristics, past medical and obstetric history, prenatal care, and delivery and newborn care for pregnant women across 25 facilities in the Lusaka public health sector. Results From June 1, 2007, to January 31, 2010, 115 552 pregnant women had prenatal and delivery information recorded in ZEPRS. Median gestation age at first prenatal visit was 23 weeks (interquartile range [IQR] 19–26). Syphilis screening was documented in 95 663 (83%) pregnancies: 2449 (2.6%) women tested positive, of whom 1589 (64.9%) were treated appropriately. 111 108 (96%) women agreed to HIV testing, of whom 22% were diagnosed with HIV. Overall, 112 813 (98%) of recorded pregnancies resulted in a live birth, and 2739 (2%) in a stillbirth. The median gestational age was 38 weeks (IQR 35–40) at delivery; the median birth weight of newborns was 3000 g (IQR 2700–3300 g). Conclusion The results demonstrate the feasibility of using a comprehensive electronic medical record in an urban African setting, and highlight its important role in ongoing efforts to improve clinical care.

Expenditure on health-care is increasing over the last years and the demographic shift leads to more elderly patients in the health-care system. Debates about the financial situation and solution about this topic are common. Direct, as well as hidden, rationing is verified by experts. This article discusses the concept of age-dependent prioritization and rationing of health-care expenditures in a cross-national setting. With a standardised questionnaire geriatric physicians in Germany and Austria were asked about their attitude and experience with health-care expenditures in elderly patients. Dimension of medical staff, organising institution and financial resources were also evaluated. The sample was tested with t-test, Mann-Whitney-U-test and explorative factor analysis. All the data were calculated with PASW 17 Statistics(®). From 419 standardised questionnaires 288 forms (60%, Germany: 123, Austria: 165) were evaluated. Differences were shown in patient-age (Germany: 80.4 y, Austria: 71.8 y), carrying capacity (Germany: 74.8, Austria: 110.8) and in medical staff as physicians (Germany: 6.8, Austria: 12.7) and nursing (Germany: 32.2, Austria: 84.3). In infrastructural basic services and normative focusing there was only marginal discrepancy, the public/ecclesiastical organising institution was 71% in both countries. Related to the different financial systems, there was less cost pressure in taking care of elderly patients in Austria. Age-dependent rationing was approved, but there was also a clear endorsement for making resources available for elderly patients in future. The discussion about rationing of health-care expenditures will still go on and therefore the impact of ageism has to be evaluated in further studies.

A random-digit-dialing telephone survey with a dual-frame sampling design was employed to obtain a probability sample of adult Puerto Ricans with diagnosed diabetes (n = 606). Demographic characteristics, health status, and indicators of diabetes medical care and self-management were collected using the standard Behavioral Risk Factor Surveillance System (BRFSS) questionnaire. A statewide sample of adults with diagnosed diabetes (n = 232) was obtained from the BRFSS for comparison. Compared to New York State adults, Puerto Ricans were significantly less likely to receive annual A1C testing (72.7% vs 84.9%), cholesterol testing (67.5% vs 87.2%), blood-pressure-lowering medication (82.4% vs 91.9%), and pneumococcal vaccination (19.3% vs 28.5%, among those aged 18 to 64 years). Puerto Ricans were also less likely to take aspirin every day or every other day to prevent cardiovascular complications (30.6% vs 40.7%). Puerto Ricans were younger and more likely to have lower educational attainment and lower income than New York State adults, but they were not significantly disadvantaged in access to health care indicated by rates of health insurance coverage, having a particular place for medical care, and frequencies of seeing a provider for diabetes. These findings support the need to introduce culturally sensitive and linguistically appropriate diabetes education programs for Puerto Ricans and continue system-based diabetes care quality improvement efforts in the areas of prevention and control of cardiovascular complications, adult immunization, and A1C testing.

Summary Newborn screening is a public health policy program involving the centralized testing laboratory, infant and their family, primary care provider, and subspecialist for confirmatory testing and follow-up of abnormal results. Cystic fibrosis (CF) newborn screening has now been enacted in all 50 states and the District of Columbia and throughout many countries in the world. Although CF neonatal screening will identify the vast majority of infants with CF, there are many factors in the newborn screening system that can lead to a missed diagnosis of CF. To inform clinicians, this article summarizes the CF newborn screening system and highlights 14 factors that can account for a missed diagnosis of CF. Care providers should maintain a high suspicion for CF if there are compatible symptoms, regardless of the results of the newborn screening test. These factors in newborn screening programs leading to a missed diagnosis of CF present opportunities for quality improvement in specimen collection, laboratory analysis of immunoreactive tryspinogen (IRT) and CF mutation testing, communication, and sweat testing.

To assess the acceptability of opportunistic search for human immunodeficiency virus (HIV). Cross-sectional, observational study. Primary Care Centres (PCC) of the Spanish National Health Care System. patients aged 18 to 65 years who had never been tested for HIV, and were having a blood test for other reasons. RECORDED VARIABLES: age, gender, stable partner, educational level, tobacco/alcohol use, reason for blood testing, acceptability of taking the HIV test, reasons for refusing to take the HIV test, and reasons for not having taken an HIV test previously. A descriptive, bivariate, multivariate (logistic regression) statistical analysis was performed. A total of 208 general practitioners (GPs) from 150 health care centres recruited 3,314 patients. Most (93.1%) of patients agreed to take the HIV test (95%CI: 92.2-93.9). Of these patients, 56.9% reported never having had an HIV test before because they considered not to be at risk of infection, whereas 34.8% reported never having been tested for HIV because their doctor had never offered it to them. Of the 6.9% who refused to take the HIV test, 73.9% considered that they were not at risk. According to the logistic regression analysis, acceptability was positively associated to age (higher among between 26 and 35 year olds, OR=1.79; 95%CI: 1.10-2.91) and non-smokers (OR=1.39; 95%CI: 1.01-1.93). Those living in towns with between 10,000 and 50,000 inhabitants showed less acceptance to the test (OR=0.57; 95%CI: 0.40-0.80). The HIV prevalence detected was 0.24% Acceptability of HIV testing is very high among patients having a blood test in primary care settings in Spain. Opportunistic search is cost-effective.

Rheumatoid factor (RF) testing is used in primary care in the diagnosis of rheumatoid arthritis (RA); however a positive RF may occur without RA. Incorrect use of RF testing may lead to increased costs and delayed diagnoses. The aim was to assess the performance of RF as a test for RA and to estimate the costs associated with its use in a primary care setting. A retrospective cohort study using the Information System for the Development of Research in Primary Care database (contains primary care records and laboratory results of >80% of the Catalonian population, Spain). Participants were patients ≥18 years with ≥1 RF test performed between 01/01/2006 and 31/12/2011, without a pre-existing diagnosis of RA. Outcome measures were an incident diagnosis of RA within 1 year of testing, and the cost of testing per case of RA. 495,434/4,796,498 (10.3%) patients were tested at least once. 107,362 (21.7%) of those tested were sero-positive of which 2768 (2.6%) were diagnosed with RA within 1 year as were 1141/388,072 (0.3%) sero-negative participants. The sensitivity of RF was 70.8% (95% CI 69.4-72.2), specificity 78.7% (78.6-78.8), and positive and negative predictive values 2.6% (2.5-2.7) and 99.7% (99.6-99.7) respectively. Approximately €3,963,472 was spent, with a cost of €1432 per true positive case. Although 10% of patients were tested for RF, most did not have RA. Limiting testing to patients with a higher pre-test probability would significantly reduce the cost of testing.

Decreasing the use of high-cost tests may reduce health care costs. To compare costs of care for patients presenting to the emergency department (ED) with suspected kidney stones randomized to 1 of 3 initial imaging tests. Patients were randomized to point-of-care ultrasound (POC US, least costly), radiology ultrasound (RAD US), or computed tomography (CT, most costly). Subsequent testing and treatment were the choice of the treating physician. A total of 2759 patients at 15 EDs were randomized to POC US (n=908), RAD US, (n=893), or CT (n=958). Mean age was 40.4 years; 51.8% were male. All medical care documented in the trial database in the 7 days following enrollment was abstracted and coded to estimate costs using national average 2012 Medicare reimbursements. Costs for initial ED care and total 7-day costs were compared using nonparametric bootstrap to account for clustering of patients within medical centers. Initial ED visit costs were modestly lower for patients assigned to RAD US: $423 ($411, $434) compared with patients assigned to CT: $448 ($438, $459) (P<0.0001). Total costs were not significantly different between groups: $1014 ($912, $1129) for POC US, $970 ($878, $1078) for RAD US, and $959 ($870, $1044) for CT. Hospital admissions contributed over 50% of total costs, though only 11% of patients were admitted. Mean total costs (and admission rates) varied substantially by site from $749 to $1239. Assignment to a less costly test had no impact on overall health care costs for ED patients. System-level interventions addressing variation in admission rates from the ED might have greater impact on costs.

Simultaneous monitoring of physiological parameters- multi-lead Electrocardiograph (ECG), Heart rate variability, and blood pressure- is imperative to all forms of medical treatments. Using an array of signal recording devices imply that the patient will have to be confined to a bed. Textiles offer durable platform for embedded sensor and communication systems. The smart healthcare textile, presented here, is a mobile system for remote/wireless data recording and conditioning. The wireless textile system has been designed to monitor a patient in a non-obstructive way. It has a potential for facilitating point of care medicine and streamlining ambulatory medicine. The sensor systems were designed and fabricated with textile based components for easy integration on textile platform. An innovative plethysmographic blood pressure monitoring system was designed and tested as an alternative to inflatable blood pressure sphygmomanometer. Flexible dry electrodes technology was implemented for ECG. The sensor systems were tested and conditioned to daily activities of patients, which is not permissible with halter type systems. The signal quality was assessed for it applicability to medical diagnosis. The results were used to corroborate smart textile sensor system's ability to function as a point of care system that can provide quality healthcare.

The influence of managed care on supply of certified nurse-midwives: an evaluation of the physician dominance thesis.

Hartley, H

1999-03-01

A key debate over the nature of professional power centers on the maintenance of physician dominance within the system of professions in health care. The changes in health care delivery and financing brought by managed care present a new context for evaluating the physician dominance thesis. I propose that increases in the supply of certified nurse-midwives, a "contending" health care professional group, are related to the expansion of managed care and may signal a decline in physician dominance. I analyze state-level data compiled from governmental, health professional, and industry sources to determine the influence of managed care market penetration, physician supply, state policy context, and demographic factors on the state-level supply of nurse-midwives. Results indicate that, despite high physician supply, nurse-midwife supply is higher in states with higher managed care penetration, as well as in those with more favorable state policy environments and a more educated demographic base. Outcomes from a series of hypothesis tests support my assertion that the expansion of managed care is altering the jurisdictional boundaries in the system of professions in health care, eroding the dominance of physicians while creating new openings for nurse-midwives.

The interaction between research and practice: a pan-European approach to managing H.pylori infection in primary care.

The transposition of evidence into clinical care presents many challenges. New knowledge may be immediately translatable to the practice setting, with barriers to be overcome before implementation. The early guidelines on Helicobacter pylori management presented an overview but were not able to take into account local factors and health care traditions, such as the non-availability of tests and established primary-secondary care relationships. Primary care is a specific specialty across most of Europe, existing within different health care systems and clinical traditions. The creation of H. pylori management guidelines, aimed at European primary care but adaptable to local national circumstances, presented a challenge in methodology and formulation. The process exposed similarities but also tensions between differing health care systems, as well as variations in the conditions in which GPs practise. Clinical differences, such as varying ulcer prevalence and drug resistance rates, highlighted the importance of guidelines being adaptable. This paper analyses the European Society for Primary Care Gastroenterology process of pan-European primary care agreement towards H.pylori management and how diverse views, traditions and national settings were reconciled through an evidence-based approach.

Individuals with end stage renal disease (ESRD), most of whom are insured by Medicare, are generally prohibited from enrolling in Medicare managed care plans (MCPs). CMS offered ESRD patients the opportunity to participate in an ESRD managed care demonstration mandated by Congress. The demonstration tested whether managed care systems would be of interest to ESRD patients and whether these approaches would be operationally feasible and efficient for treating ESRD patients. This article examines the structure, implementation, and operational outcomes of the three demonstration sites, focusing on: the structure of these managed care programs for ESRD patients, requirements needed to attract and enroll patients, and the challenges of introducing managed care programs in the ESRD arena.

Telehealth cost analysis has become a crucial issue for governments in recent years. In this study, we examined cases of metabolic syndrome in Hualien County, Taiwan. This research adopted the framework proposed by Marchand to establish a study process. In addition, descriptive statistics, a t test, analysis of variance, and regression analysis were employed to analyze 100 questionnaires. The results of the t$ test revealed significant differences in medical health expenditure, number of clinical visits for medical treatment, average amount of time spent commuting to clinics, amount of time spent undergoing medical treatment, and average number of people accompanying patients to medical care facilities or assisting with other tasks in the past one month, indicating that offering telehealth care services can reduce health expenditure. The statistical analysis results revealed that customer satisfaction has a positive effect on reducing health expenditure. Therefore, this study proves that telehealth care systems can effectively reduce health expenditure and directly improve customer satisfaction with medical treatment.

The objective was to investigate sensor measurement uncertainty for intracerebral probes inserted during neurosurgery and remaining in situ during neurocritical care. This describes a prospective observational study of two sensor types and including performance of the complete sensor-bedside monitoring and readout system. Sensors from 16 patients with severe traumatic brain injury (TBI) were obtained at the time of removal from the brain. When tested, 40% of sensors achieved the manufacturer temperature specification of 0.1 °C. Pressure sensors calibration differed from the manufacturers at all test pressures in 8/20 sensors. The largest pressure measurement error was in the intraparenchymal triple sensor. Measurement uncertainty is not influenced by duration in situ. User experiences reveal problems with sensor 'handling', alarms and firmware. Rigorous investigation of the performance of intracerebral sensors in the laboratory and at the bedside has established measurement uncertainty in the 'real world' setting of neurocritical care.

Automated screening method for determining optimum preservative systems for personal and home care products.

Lenczewski, M E; Kananen, L L

A procedure was designed to determine the minimum preservative level (MPL) for personal and home care products. A highly preserved sample and an unpreserved sample were combined at different concentrations within a 96-well microtiter plate by using an autodilutor. A unique tip design made it possible to accurately deliver viscous test materials that cannot be dispensed using vacuum- or fluid-filled systems. After inoculation, the sample was evaluated at a specified time interval for the presence of surviving bacteria, yeast, and mold. The lowest concentration of preservative with no microbial growth is the recommended level of preservative for the product. Because sample turbidity may interfere with determination of the endpoint, a colorimetric endpoint was used to indicate growth of microorganisms and to differentiate product from growth. The predicted levels were tested with a modified Cosmetic, Toiletry, and Fragrance Association method. The method successfully predicted effective preservative levels in many personal and home care products with a broad range of viscosities.

Inappropriate medication use is common in the care of patients with CKD. The feasibility of a simple mobile health tool designed to advise patients on safe medication usage in CKD was examined. Participants with predialysis CKD (defined as eGFR<60 ml/min per 1.73 m(2)) in the Safe Kidney Care Cohort Study were recruited for home usability testing of a novel medication inquiry system between January and September of 2013. Testing was through two mobile platforms: (1) short messaging service text or (2) personal digital assistant (e.g., iPod Touch). Twenty participants (one half assigned to one device and one half assigned to the other device) were enrolled and received an in-center tutorial on device usage before the end of the study visit. Participants were subsequently mailed three sample pill bottles with the name of randomly selected medications and asked to input these medications into the medication inquiry system. The medication inquiry system response options were as follows: (1) safe in CKD, (2) not safe in CKD, (3) use with caution/speak with your health care provider, or (4) error message (for an incorrectly inputted medication). Participants were asked to record the response issued by the medication inquiry system for each medication sent for usability testing. A user satisfaction survey was administered after completion of the protocol. All participants owned a mobile telephone, but few owned a smartphone. Of 60 total medication queries, there were only three recorded errors, two of which occurred in the short messaging service texting group. Overall satisfaction with the application was high, with slightly higher satisfaction noted in the personal digital assistant group compared with the short messaging service group. The mobile health medication inquiry system application had general ease of use and high acceptance across two platforms among individuals representative of the CKD population. Tailored mobile health technology may improve medication safety in CKD. Copyright © 2015 by the American Society of Nephrology.

Policy makers require estimates of comparative effectiveness that apply to the population of interest, but there has been little research on quantitative approaches to assess and extend the generalizability of randomized controlled trial (RCT)-based evaluations. We illustrate an approach using observational data. Our example is the Whole Systems Demonstrator (WSD) trial, in which 3230 adults with chronic conditions were assigned to receive telehealth or usual care. First, we used novel placebo tests to assess whether outcomes were similar between the RCT control group and a matched subset of nonparticipants who received usual care. We matched on 65 baseline variables obtained from the electronic medical record. Second, we conducted sensitivity analysis to consider whether the estimates of treatment effectiveness were robust to alternative assumptions about whether "usual care" is defined by the RCT control group or nonparticipants. Thus, we provided alternative estimates of comparative effectiveness by contrasting the outcomes of the RCT telehealth group and matched nonparticipants. For some endpoints, such as the number of outpatient attendances, the placebo tests passed, and the effectiveness estimates were robust to the choice of comparison group. However, for other endpoints, such as emergency admissions, the placebo tests failed and the estimates of treatment effect differed markedly according to whether telehealth patients were compared with RCT controls or matched nonparticipants. The proposed placebo tests indicate those cases when estimates from RCTs do not generalize to routine clinical practice and motivate complementary estimates of comparative effectiveness that use observational data. Future RCTs are recommended to incorporate these placebo tests and the accompanying sensitivity analyses to enhance their relevance to policy making. © The Author(s) 2015.

Sebern, Margaret D; Woda, Aimee

2012-04-01

Up to half of heart failure (HF) patients are readmitted to hospitals within 6 months of discharge. Many readmissions are linked to inadequate self-care or family support. To improve care, practitioners may need to intervene with both the HF patient and family caregiver. Despite the recognition that family interventions improve patient outcomes, there is a lack of evidence to support dyadic interventions in HF. Thus, the purpose of this study was to test the Shared Care Dyadic Intervention (SCDI) designed to improve self-care in HF. The theoretical base of the SCDI was a construct called Shared Care. Shared Care represents a system of processes used in family care to exchange support. Key findings were as follows: the SCDI was acceptable to both care partners and the data supported improved shared care for both. For the patient, there were improvements in self-care. For the caregivers, there were improvements in relationship quality and health.

This is an analysis of the health and nutritional profile of users of the Unified Health System admitted to a City Academy in Belo Horizonte, Minas Gerais during a triennium. It is a cross-sectional study with users> 20 years and socio-demographic characteristics, health habits, food intake and anthropometrics were gathered. Kolmogorov-Smirnov tests, ANOVA, Kruskal-Wallis test, chi-square and Fisher exact test were applied. There was a high prevalence of hypertensive subjects (41.6%), overweight (70.6%) and metabolic risks associated with obesity (67.6%). About 40% of entrants had 1-3 chronic diseases and over 65% used medication daily. There was an imbalance in daily consumption of fruits and vegetables (75.3%), fatty meat (72.4%) and sweetened drinks (54.2%). They had low education and income, and inadequate eating habits and high prevalence of hypertension, overweight and metabolic risks associated with obesity, which suggests users seeking health care services for treatment of diseases. This illustrates the perceived quest for cure, further demonstrating the lack of healthcare initiatives in the population. This reveals the need to review the actions at different levels of health care, to promote greater comprehensiveness of care provided.

Is there a doctor in the house? : The presence of physicians in the direct-to-consumer genetic testing context.

Howard, Heidi Carmen; Borry, Pascal

2012-04-01

Over the last couple of years, many commercial companies, the majority of which are based in the USA, have been advertising and offering direct-to-consumer (DTC) genetic testing services outside of the established health care system, and often without any involvement from a health care professional. In the last year, however, a number of DTC genetic testing companies have changed their provision model such that consumers must now contact a health care professional before being able to order the genetic testing service. In discussing the advent of this new model of service provision, this article also reviews the ethical and social issues surrounding DTC genetic testing and addresses the potential motivations for change, some barriers to achieving truly appropriate medical supervision and the present reality of DTC genetic testing for some psychiatric and neurological disorders. Since the advent of these commercial activities, critics have pointed a finger at the lack of medical supervision surrounding these services. The discussion herein, however, reveals how difficult it may be, despite the addition of a physician, to actually achieve adequate medical supervision within the present context of DTC genetic testing.

As most genital Chlamydia trachomatis infections are asymptomatic, many patients do not seek health care for testing. Infections remain undiagnosed and untreated. We studied whether screening with information and home sampling resulted in more young people getting tested, diagnosed and treated for chlamydia in the three months following the intervention compared to the current strategy of testing in the health care system. We conducted a population based randomized controlled trial among all persons aged 18-25 years in one Norwegian county (41 519 persons). 10 000 persons (intervention) received an invitation by mail with chlamydia information and a mail-back urine sampling kit. 31 519 persons received no intervention and continued with usual care (control). All samples from both groups were analysed in the same laboratory. Information on treatment was obtained from the Norwegian Prescription Database (NorPD). We estimated risk ratios and risk differences of being tested, diagnosed and treated in the intervention group compared to the control group. In the intervention group 16.5% got tested and in the control group 3.4%, risk ratio 4.9 (95% CI 4.5-5.2). The intervention led to 2.6 (95% CI 2.0-3.4) times as many individuals being diagnosed and 2.5 (95% CI 1.9-3.4) times as many individuals receiving treatment for chlamydia compared to no intervention in the three months following the intervention. In Norway, systematic screening with information and home sampling results in more young people being tested, diagnosed and treated for chlamydia in the three months following the intervention than the current strategy of testing in the health care system. However, the study has not established that the intervention will reduce the chlamydia prevalence or the risk of complications from chlamydia.

The Impact of the Affordable Care Act on Funding for Newborn Screening Services.

PubMed

Costich, Julia F; Durst, Andrea L

2016-01-01

The Affordable Care Act requires most health plans to cover the federal Recommended Uniform Screening Panel of newborn screening (NBS) tests with no cost sharing. However, state NBS programs vary widely in both the number of mandated tests and their funding mechanisms, including a combination of state laboratory fees, third-party billing, and other federal and state funding. We assessed the potential impact of the Affordable Care Act coverage mandate on states' NBS funding. We performed an extensive review of the refereed literature, federal and state agency reports, relevant organizations' websites, and applicable state laws and regulations; interviewed 28 state and federal officials from August to December 2014; and then assessed the interview findings manually. Although a majority of states had well-established systems for including laboratory-based NBS tests in bundled charges for newborn care, billing practices for critical congenital heart disease and newborn hearing tests were less uniform. Most commonly, birthing facilities either prepaid the costs of laboratory-based tests when acquiring the filter paper kits, or the facilities paid for the tests when the kits were submitted. Some states had separate arrangements for billing Medicaid, and smaller facilities sometimes contracted with hearing test vendors that billed families separately. Although the Affordable Care Act coverage mandate may offset some state NBS funding for the screenings themselves, federal support is still required to assure access to the full range of NBS program services. Limiting reimbursement to the costs of screening tests alone would undermine the common practice of using screening charges to fund follow-up services counseling, and medical food or formula, particularly for low-income families.

Prompt entry to care after HIV diagnosis benefits the infected individual and reduces the likelihood of further transmission of the virus. The New York State HIV Testing Law of 2010 requires diagnosing providers to refer persons newly diagnosed with HIV to follow-up medical care. This study used routinely collected HIV-related laboratory data from the New York State HIV surveillance system to assess whether the fraction of newly diagnosed cases entering care within 90 days of diagnosis increased after the implementation of the law. Laboratory data on 23,302 newly diagnosed cases showed that entry to care within 90 days rose steadily from 72.0% in 2007 to 85.4% in 2012. The rise was observed across all race/ethnic groups, ages, transmission risk groups, sexes, and regions of residence. Logistic regression analyses of entry to care pre-law and post-law, controlling for demographic characteristics, transmission risk, and geographic area, indicate that percentage of newly diagnosed cases entering care within 90 days grew more rapidly in the post-law period. This is consistent with a positive effect of the law on entry to care.

In this paper, we describe a miniaturised image-based fluorescence detection system and demonstrate its viability as a highly sensitive tool for point-of-care-analysis of drugs of abuse in human sweat with a focus on monitor individuals for drugs of abuse. Investigations of miniaturised and low power optoelectronic configurations and methodologies for real-time image analysis were successfully carried out. The miniaturised fluorescence detection system was validated against a reference detection system under controlled laboratory conditions by analysing spiked sweat samples in dip stick and then strip with sample pad. As a result of the validation studies, a 1 ng mL-1 limit of detection of cocaine in sweat and full agreement of test results with the reference detection system can be reported. Results of the investigations open the way towards a detection system that integrates a hand-held fluorescence reader and a wearable skinpatch, and which can collect and in situ analyse sweat for the presence of cocaine at any point for up to tenths hours.

This article is a report of a quasi-experimental study of the effectiveness of the Omaha System intervention on the women's health promotion lifestyle profile and the quality of life. The Omaha System is a model for organizing, documenting and evaluating the outcomes of comprehensive, community-based, client-centred care. Therefore, the Omaha System is important for public health nurses whose aim is to protect and promote health. However, few studies addressed the influence of the Omaha System on health promotion activities or quality of life in adult population. The design of the study was one-group pre-test and post-test. The study took place in Turkey in 2007; the sample comprised 76 women from an urban primary healthcare centre. The women completed questionnaires consisting of demographical characteristics, the health promotion lifestyle profile scale developed by Walker and colleagues and the quality of life scale developed by Burckhardt and colleagues. The researcher then visited selected women in their home weekly or biweekly for a 4-month period. At the end of intervention, the scales were applied to the women as the post-test. The mean scores of self-actualization, health responsibility, interpersonal support, stress management subscales of the health promotion lifestyle profile and the total score increased in post-test, except for nutrition subscale. There were statistically significant differences between pre- and post-test scores. This study demonstrated that the Omaha System intervention increases health promotion lifestyle profile of the women. It is recommended as a nursing care to health promotion. © 2011 Blackwell Publishing Ltd.

The implementation of a technology such as health information exchange (HIE) through a Regional Health Information System (RHIS) may improve the mobilization of health care information electronically across organizations. There is a need to coordinate care and bring together regional and local stakeholders. To describe how HIE had influenced health care delivery in one hospital district area in Finland. Trend analysis was used to evaluate the influence of a regional HIE. We conducted a retrospective, longitudinal study for the period 2004-2008 for the eleven federations of municipalities in the study area. We reviewed statistical health data from the time of implementation of an RHIS. The t-test was used to determine statistical significance. The selected outcomes were the data obtained from the regional database on total appointments, emergency department visits, laboratory tests and radiology examinations, and selected laboratory tests and radiology examinations carried out in both primary care and special health care. Access to HIE may have influenced health care delivery in the study area. There are indications that there is a connection between access to regional HIE and the number of laboratory tests and radiology examinations performed in both primary care and specialized health care, as observed in the decreased frequency in outcomes such as radiology examinations, number of appointments, and emergency department visits in the study environment. The decreased frequencies of the latter suggest an increased efficiency of outpatient care, but we were not able to estimate to what extent the readily available comprehensive clinical information contributed to these trends. Outcome assessment of HIE through an RHIS is essential for the success of health information technology (HIT) and as evidence to use in the decision-making process. As health care information becomes more digital, it increases the potential for a strong HIE effect on health care delivery.

To assess the use of the Neonatal Therapeutic Intervention Scoring System (NTISS) as a tool to quantify the use of technology in neonatal intensive care units, in order to detect discrepancies in the care provided to high-risk newborn infants. Prospective, descriptive, observational study about the use of technology in two neonatal intensive care units (one public and one private). The NTISS was calculated on a daily basis up to the discharge or death of preterm newborns with gestational age equal to or less than 32 weeks. We gathered data about prenatal clinical conditions, birth characteristics, and conditions on admission to the intensive care unit, as well as about the morbidities developed during the hospital stay. The risks of preterm newborns were adjusted by means of the Score for Neonatal Acute Physiology, Perinatal Extension, Version II (SNAPPE-II). Student's t test, chi-square test, Fisher's exact test, and the Mann-Whitney/Wilcoxon's test were used for the descriptive analysis. The study was approved by the local Research and Ethics Committee. We assessed 44 newborn infants from the public intensive care unit and 52 from the private one. On admission, the severity score (SNAPPE-II) and the overall NTISS were statistically similar in both care units. The curve for the use of technology showed a gradual and progressive decreasing pattern in both care units up to the 31st day. Thereafter, there was a continuous downward trend in the private care unit, but a significant increase in the overall NTISS in the public care unit. The patients from the public care unit developed more morbidities than those from the private unit. Patients with similar clinical pictures can be treated with different levels of technological resources. This may have a direct impact on morbidities and on healthcare costs. The NTISS allowed monitoring healthcare and proved efficient in detecting discrepancies in practices that could influence clinical outcomes and operating costs.

Prioritizing personalized, proactive, patient-driven health care is among the Veterans Health Administration's (VHA's) transformational initiatives. As one of the largest integrated healthcare systems, the VHA sets standards for performance measures and outcomes achieved in quality of care. Evidence-based practice (EBP) is a hallmark in oncology nursing care. EBP can be linked to positive outcomes and improving quality that can be influenced directly by nursing interventions. VHA oncology nurses had the opportunity to partner with the Oncology Nursing Society (ONS), ONS Foundation, and the Joint Commission in the multiyear development of a comprehensive approach to quality cancer care. Building on a platform of existing measures and refining measurement sets culminated in testing evidence-based, nursing-sensitive quality measures for reliability through the ONS Foundation-supported Breast Cancer Care (BCC) Quality Measures Set. The BCC Measures afforded the VHA to have its many sites collectively assess documentation of the symptoms of patients with breast cancer, the use of colony-stimulating factors, and education about neutropenia precautions provided. Parallel paths of the groups, seeking evidence-based measures, led to the perfect partnership in the VHA's journey in pilot testing the BCC Measures in veterans with breast cancer. This generated further quality assessments and continuous improvement projects for spread and sustainability throughout the VHA.

Management of heart failure is complex, often involving interaction with multiple providers, monitoring of symptoms, and numerous medications. Employing principles of user-centered design, we developed a high- fidelity prototype of a mobile system for heart failure self-management and care coordination. Participants, including both heart failure patients and health care providers, tested the mobile system during a one-hour one-on-one session with a facilitator. The facilitator interviewed participants about the strengths and weaknesses of the prototype, necessary features, and willingness to use the technology. We performed a qualitative content analysis using the transcripts of these interviews. Fourteen distinct themes were identified in the analysis. Of these themes, integration, technology literacy, memory, and organization were the most common. Privacy was the least common theme. Our study suggests that this integration is essential for adoption of a mobile system for chronic disease management and care coordination.

Objective To systematically review the literature on image-based telemedicine for medical expert consultation in acute care of injuries, considering system, user, and clinical aspects. Design Systematic review of peer-reviewed journal articles. Data sources Searches of five databases and in eligible articles, relevant reviews, and specialized peer-reviewed journals. Eligibility criteria Studies were included that covered teleconsultation systems based on image capture and transfer with the objective of seeking medical expertise for the diagnostic and treatment of acute injury care and that presented the evaluation of one or several aspects of the system based on empirical data. Studies of systems not under routine practice or including real-time interactive video conferencing were excluded. Method The procedures used in this review followed the PRISMA Statement. Predefined criteria were used for the assessment of the risk of bias. The DeLone and McLean Information System Success Model was used as a framework to synthesise the results according to system quality, user satisfaction, information quality and net benefits. All data extractions were done by at least two reviewers independently. Results Out of 331 articles, 24 were found eligible. Diagnostic validity and management outcomes were often studied; fewer studies focused on system quality and user satisfaction. Most systems were evaluated at a feasibility stage or during small-scale pilot testing. Although the results of the evaluations were generally positive, biases in the methodology of evaluation were concerning selection, performance and exclusion. Gold standards and statistical tests were not always used when assessing diagnostic validity and patient management. Conclusions Image-based telemedicine systems for injury emergency care tend to support valid diagnosis and influence patient management. The evidence relates to a few clinical fields, and has substantial methodological shortcomings. As in the case of telemedicine in general, user and system quality aspects are poorly documented, both of which affect scale up of such programs. PMID:24887257

Introduction Building integrated services in a primary care setting is considered an essential important strategy for establishing a high-quality and affordable health care system. The theoretical foundations of such integrated service models are described by the Rainbow Model of Integrated Care, which distinguishes six integration dimensions (clinical, professional, organisational, system, functional and normative integration). The aim of the present study is to refine the Rainbow Model of Integrated Care by developing a taxonomy that specifies the underlying key features of the six dimensions. Methods First, a literature review was conducted to identify features for achieving integrated service delivery. Second, a thematic analysis method was used to develop a taxonomy of key features organised into the dimensions of the Rainbow Model of Integrated Care. Finally, the appropriateness of the key features was tested in a Delphi study among Dutch experts. Results The taxonomy consists of 59 key features distributed across the six integration dimensions of the Rainbow Model of Integrated Care. Key features associated with the clinical, professional, organisational and normative dimensions were considered appropriate by the experts. Key features linked to the functional and system dimensions were considered less appropriate. Discussion This study contributes to the ongoing debate of defining the concept and typology of integrated care. This taxonomy provides a development agenda for establishing an accepted scientific framework of integrated care from an end-user, professional, managerial and policy perspective. PMID:25759607

2016-01-01

Summary Background Electronic health records (EHRs) have potential to facilitate reliable communication and follow-up of test results. However, limitations in EHR functionality remain, leading practitioners to use workarounds while managing test results. Workarounds can lead to patient safety concerns and signify indications as to how to build better EHR systems that meet provider needs. Objective To understand why primary care practitioners (PCPs) use workarounds to manage test results by analyzing data from a previously conducted national cross-sectional survey on test result management. Methods We conducted a secondary data analysis of quantitative and qualitative data from a national survey of PCPs practicing in the Department of Veterans Affairs (VA) and explored the use of workarounds in test results management. We used multivariate logistic regression analysis to examine the association between key sociotechnical factors that could affect test results follow-up (e.g., both technology-related and those unrelated to technology, such as organizational support for patient notification) and workaround use. We conducted a qualitative content analysis of free text survey data to examine reasons for use of workarounds. Results Of 2554 survey respondents, 1104 (43%) reported using workarounds related to test results management. Of these 1028 (93%) described the type of workaround they were using; 719 (70%) reported paper-based methods, while 230 (22%) used a combination of paper- and computer-based workarounds. Primary care practitioners who self-reported limited administrative support to help them notify patients of test results or described an instance where they personally (or a colleague) missed results, were more likely to use workarounds (p=0.02 and p=0.001, respectively). Qualitative analysis identified three main reasons for workaround use: 1) as a memory aid, 2) for improved efficiency and 3) for facilitating internal and external care coordination. Conclusion Workarounds to manage EHR-based test results are common, and their use results from unmet provider information management needs. Future EHRs and the respective work systems around them need to evolve to meet these needs. PMID:27437060

To determine the costs of Rapid Syphilis Test (RSTs) as compared with rapid plasma reagin (RPR) when implemented in a Tanzanian setting, and to determine the relative impact of a quality assurance (QA) system on the cost of RST implementation. The incremental costs for RPR and RST screening programmes in existing antenatal care settings in Geita District, Tanzania were collected for 9 months in subsequent years from nine health facilities that varied in size, remoteness and scope of antenatal services. The costs per woman tested and treated were estimated for each facility. A sensitivity analysis was constructed to determine the impact of parameter and model uncertainty. In surveyed facilities, a total of 6362 women were tested with RSTs compared with 224 tested with RPR. The range of unit costs was $1.76-$3.13 per woman screened and $12.88-$32.67 per woman treated. Unit costs for the QA system came to $0.51 per woman tested, of which 50% were attributed to salaries and transport for project personnel. Our results suggest that rapid syphilis diagnostics are very inexpensive in this setting and can overcome some critical barriers to ensuring universal access to syphilis testing and treatment. The additional costs for implementation of a quality system were found to be relatively small, and could be reduced through alterations to the programme design. Given the potential for a quality system to improve quality of diagnosis and care, we recommend that QA activities be incorporated into RST roll-out.

Results of a recent demonstration project evaluating feasibility, acceptability, and cost of a Web-based sexually transmitted infection (STI) testing and e-prescription treatment program (eSTI) suggest that this approach could be a feasible alternative to clinic-based testing and treatment, but the results need to be confirmed by a randomized comparative effectiveness trial. We modeled a decision tree comparing (1) cost of eSTI screening using a home collection kit and an e-prescription for uncomplicated treatment versus (2) hypothetical costs derived from the literature for referral to standard clinic-based STI screening and treatment. Primary outcome was number of STIs detected. Analyses were conducted from the clinical trial perspective and the health care system perspective. The eSTI strategy detected 75 infections, and the clinic referral strategy detected 45 infections. Total cost of eSTI was $94,938 ($1266/STI detected) from the clinical trial perspective and $96,088 ($1281/STI detected) from the health care system perspective. Total cost of clinic referral was $87,367 ($1941/STI detected) from the clinical trial perspective and $71,668 ($1593/STI detected) from the health care system perspective. Results indicate that eSTI will likely be more cost-effective (lower cost/STI detected) than clinic-based STI screening, both in the context of clinical trials and in routine clinical care. Although our results are promising, they are based on a demonstration project and estimates from other small studies. A comparative effectiveness research trial is needed to determine actual cost and impact of the eSTI system on identification and treatment of new infections and prevention of their sequelae.

The channeling demonstration involved provision of comprehensive case management and direct service expansion. This article considers the former. Under both models, comprehensive case management was implemented largely as intended; moreover, channeling substantially increased the receipt of comprehensive care management. However, channeling was not a pure test of the effect of comprehensive case management: roughly 10-20 percent of control group members received comparable case management services. This was particularly the case for the financial control model. Thus, the demonstration was not a test of case management compared to no case management; rather, it compared channeling case management to the existing community care system, which already was providing comprehensive case management to some of the population eligible for channeling.

The proportion of women with previous gestational diabetes mellitus (GDM) receiving postpartum diabetes testing is far less than desired. Even in health care systems with high testing rates, some women remain untested. We explored what helps and what hinders women to obtain recommended testing. In this mixed methods study, we recruited 139 patients with a history of GDM in their most recent pregnancy (6 months to 4.5 years before study enrollment) from a delivery system that had instituted a quality improvement program to increase postpartum diabetes testing rates. We determined whether they had received a postpartum diabetes test according to American Diabetes Association guidelines. Using survey data, we ran logistic regression models to assess correlates of testing status, and we conducted in-depth interviews with 22 women to provide greater context to their survey responses. Of the 139 women, 21 women (15%) did not complete recommended diabetes testing. From the survey data, women who visited a primary care provider had 72% (95% CI, 0.09-0.83) lesser odds of not having been tested. From the qualitative interviews, difficulty fitting testing around work and caregiver demands were the most common reasons for not testing. Untested women interpreted providers' reassurances that diabetes would resolve after delivery and lack of reminders to reschedule missed appointments and to complete diabetes testing as indicators that their physicians were not concerned about their diabetes risk. Among hard-to-reach women, multiple demands on their time were common explanations for not receiving a postpartum diabetes test. Consistent messages regarding long-term diabetes risk during pregnancy, access to postpartum primary care and convenient lab appointments, and systematic reminders to providers and patients are approaches that, in combination, may influence more resistant women to test.

eHealth provides a novel opportunity to exploit the advantages of the Nordic countries in psychiatric genetic research, building on the public health care system, biobanks, and registries.

Andreassen, Ole A

2017-07-07

Nordic countries have played an important role in the recent progress in psychiatric genetics, both with large well-characterized samples and expertise. The Nordic countries have research advantages due to the organization of their societies, including system of personal identifiers, national health registries with information about diseases, treatment and prescriptions, and a public health system with geographical catchment areas. For psychiatric genetic research, the large biobanks and population surveys are a unique added value. Further, the population is motivated to participate in research, and there is a trust in the institutions of the society. These factors have been important for Nordic contributions to biomedical research, and particularly psychiatric genetics. In the era of eHealth, the situation seems even more advantageous for Nordic countries. The system with public health care makes it easy to implement national measures, and most of the Nordic health care sector is already based on electronic information. The potential advantages regarding informed consent, large scale recruitment and follow-up, and longitudinal cohort studies are tremendous. New precision medicine approaches can be tested within the health care system, with an integrated approach, using large hospitals or regions of the country as a test beds. However, data protection and legal framework have to be clarified. In order to succeed, it is important to keep the people's trust, and maintain the high ethical standards and systems for secure data management. Then the full potential of the Nordic countries can be leveraged in the new era of precision medicine including psychiatric genetics. © 2017 Wiley Periodicals, Inc.

Demand management is an area of laboratory activity, which is becoming increasingly important. Within the health-care system, demand management can be defined as the use of health resources to maximise its utility. Tygerberg Hospital has introduced an electronic gate-keeping system. Chemistry tests which generate the highest cost are subjected to this system and may be automatically rejected according to a set of rules. This study aimed: (1) to identify the number of chemistry tests rejected by the eGK; (2) to identify which of these rejected tests were subsequently restored and (3) to assess the impact of rejections on clinical outcome and cost-saving. A retrospective audit was conducted to determine the number of chemistry tests rejected and subsequently restored over a 6-month period. The case-notes of patients for whom requested tests previously rejected had been restored were randomly selected and investigated to assess clinical impact. Any cost-saving was calculated. A total of 68,480 tests were subjected to gate-keeping, and 4605 tests (6.7%) were rejected while 679 (14.7%) of these were restored by the requestor phoning the laboratory after obtaining authorisation. After examining a subset of clinical notes it was found that in most cases (80%), patient care was unaffected. The total cost saved was £ 25,387. The majority of the rejected tests were unnecessary and following rejection, real savings were made. Electronic gate-keeping is a simple, effective and sustainable method of demand management. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Sports medicine has matured as a focused discipline within primary care with the number of primary care sports medicine physicians growing annually. The practices of these physicians range from "part-time" sports medicine as a part of a broader practice in their primary specialty, to functioning as a full-time team physician for a university or college. Managed care organizations are increasingly incorporating primary care sports medicine providers into their organizations. The optimal role of these providers in a managed care system has not been described. A descriptive analysis was made of patient contacts in a referral-based, free-standing primary care sports medicine clinic associated with a large managed care system. This study describes patient information including demographic data, referral source, primary diagnosis, specialized diagnostic testing, and subsequent specialty consultation. A total of 1857 patient contacts were analyzed. New patients were referred from a full range of physicians both primary care (family practice, internal medicine, pediatrics, and emergency physicians) and other specialists, with family practice clinic providers (physicians, physician assistants, and nurse practitioners) accounting for the largest percentage of new referrals. The majority of patient visits were for orthopedic injuries (95.4%); the most frequently involved injury sites were: knee (26.5%), shoulder (18.2%), back (14.3%), and ankle (10%). The most common types of injury were: tendinitis (21.3%), chronic anterior knee pain (10.6%), and ligament sprains (9.9%). Specialized testing was requested for 8% of all patients. The majority of patients were treated at the Ft Belvoir Sports Medicine Clinic by primary care sports medicine physicians without further specialty referral. Primary care sports medicine physicians offer an intermediate level of care for patients while maintaining a practice in their primary care specialty. This dual practice is ideal in the managed care setting. This study demonstrates the complementary nature of primary care sports medicine and orthopedics, with the primary care sports medicine physician reducing the demand on orthopedists for nonsurgical treatment. This study also demonstrates the need for revision in the orthopedic curriculum for primary care physicians.

The diagnosis of heparin-induced thrombocytopenia (HIT) may be challenging in critically ill patients, as heparin exposures are ubiquitous, and thrombocytopenia is common. Unwarranted ordering and incorrect interpretation of heparin antibody tests can expose a patient to adverse drug events and imposes a significant economic burden on our health care system. A prospective, observational study was performed over 4 months on all adult patients located in 5 intensive care units, with a heparin antibody test ordered. A platelet factor 4/heparin enzyme-linked immunosorbent assay (ELISA) test was ordered in 131 patients. In total, 110 patients had a low 4Ts score (0-3), and of these 103 had a negative ELISA result. In patients with a low 4Ts score, 0 (0%) of 110 had an optical density value >1.0. One hundred twenty-nine patients (98%) had another possible cause of thrombocytopenia identified. In critically ill patients, low 4Ts scores indicate a low probability of HIT, and heparin antibody testing in these patients is not useful.

Testing for the presence of antinuclear antibodies (ANAs) is a key step in the diagnosis of systemic lupus erythematosus (SLE) and other systemic autoimmune rheumatic diseases (SARD). The standard slide-based indirect immunofluorescence (IIF) test is widely used, but is limited by a relative lack of specificity for SLE and not all SARD-ANAs are detected. Alternative immunoassays that might offer enhanced diagnostic and prognostic information have evolved, and some of these have entered clinical practice. This review summarizes the current state of ANA testing and multiplex techniques for detecting other autoantibodies, the possibility of point-of-care testing, and approaches for applications in early disease stages.

Development and validation of a short version of the Assessment of Chronic Illness Care (ACIC) in Dutch Disease Management Programs

2011-01-01

Background In the Netherlands the extent to which chronically ill patients receive care congruent with the Chronic Care Model is unknown. The main objectives of this study were to (1) validate the Assessment of Chronic Illness Care (ACIC) in the Netherlands in various Disease Management Programmes (DMPs) and (2) shorten the 34-item ACIC while maintaining adequate validity, reliability, and sensitivity to change. Methods The Dutch version of the ACIC was tested in 22 DMPs with 218 professionals. We tested the instrument by means of structural equation modelling, and examined its validity, reliability and sensitivity to change. Results After eliminating 13 items, the confirmatory factor analyses revealed good indices of fit with the resulting 21-item ACIC (ACIC-S). Internal consistency as represented by Cronbach's alpha ranged from 'acceptable' for the 'clinical information systems' subscale to 'excellent' for the 'organization of the healthcare delivery system' subscale. Correlations between the ACIC and ACIC-S subscales were also good, ranging from .87 to 1.00, indicating acceptable coverage of the core areas of the CCM. The seven subscales were significantly and positively correlated, indicating that the subscales were conceptually related but also distinct. Paired t-tests results show that the ACIC scores of the original instrument all improved significantly over time in regions that were in the process of implementing DMPs (all components at p < 0.0001). Conclusion We conclude that the psychometric properties of the ACIC and the ACIC-S are good and the ACIC-S is a promising alternate instrument to assess chronic illness care. PMID:21726439

Objectives Gestational diabetes mellitus (GDM) greatly increases the risk of developing diabetes in the decade after delivery, but few women receive appropriately timed postpartum glucose testing (PPGT) or a referral to primary care (PC) for continued monitoring. This qualitative study was designed to identify barriers and facilitators to testing and referral from patient and providers' perspectives. Methods We interviewed patients and clinicians in depth about knowledge, values, priorities, challenges, and recommendations for increasing PPGT rates and PC linkage. Interviews were coded with NVIVO data analysis software, and analyzed using an implementation science framework. Results Women reported motivation to address GDM for the health of the fetus. Most women did not anticipate future diabetes for themselves, and focused on delivery outcomes rather than future health risks. Patients sought and received reassurance from clinicians, and were unlikely to discuss early onset following GDM or preventive measures. PPGT barriers described by patients included provider not mentioning the test or setting it up, transportation difficulties, work responsibilities, fatigue, concerns about fasting while breastfeeding, and timing of the test after discharge from obstetrics, and no referral to PC for follow-up. Practitioners described limited communication among multiple care providers during pregnancy and delivery, systems issues, and separation of obstetrics from PC. Conclusions Patients' barriers to PPGT included low motivation for self-care, structural obstacles, and competing priorities. Providers reported the need to balance risk with reassurance, and identified systems failures related to test timing, limitations of electronic medical record systems (EMR), lack of referrals to PC, and inadequate communication between specialties. Prevention of early onset has great potential for medical cost savings and improvements in quality of life. PMID:27347422

Gestational diabetes mellitus (GDM) greatly increases the risk of developing diabetes in the decade after delivery, but few women receive appropriately timed postpartum glucose testing (PPGT) or a referral to primary care (PC) for continued monitoring. This qualitative study was designed to identify barriers and facilitators to testing and referral from patient and providers' perspectives.

The basic criterion for the overall quality system in medical biochemistry laboratories concerning equipment, premises and laboratory staff in primary health care (PHC) (Regulations on quality systems and good laboratory practice of the Croatian Medical Biochemists Chamber, 1995, Regulations on categorization of medical biochemistry laboratories of the Croatian Medical Biochemists Chamber, 1996, EC4: Essential criteria for quality systems in medical laboratories. Eur J Clin Chem Clin Biochem 1997 in medical biochemical laboratories included in the First Croatia health project, Primary health care subproject, has been met by the marketing approach to the project. The equipment ensuring implementation of the complete laboratory program (NN/96), more accurate and precise analytical procedures, and higher reliability of laboratory test results compared with previous equipment, has been purchased by an international tender. Uniform technology and methods of analysis have ensured high standards of good laboratory services, yielding test results than can be transferred from primary to secondary health care level. The new equipment has improved organization between central and detached medical biochemistry laboratory units, while the high quality requirement has led to improvement in the staff structure, e.g., medical biochemists have been employed in laboratories that had previously worked without such a professional. Equipment renewal has been accompanied by proper education for all levels of PHC professionals.

In developing countries, the deployment of medical diagnostic technologies remains a challenge because of infrastructural limitations (e.g. refrigeration, electricity), and paucity of health professionals, distribution centers and transportation systems. Here we demonstrate the technical development and clinical testing of a novel electronics enabled microfluidic paper-based analytical device (EE-μPAD) for quantitative measurement of micronutrient concentrations in decentralized, resource-limited settings. The system performs immune-detection using paper-based microfluidics, instrumented with flexible electronics and optoelectronic sensors in a mechanically robust, ultrathin format comparable in size to a credit card. Autonomous self-calibration, plasma separation, flow monitoring, timing and data storage enable multiple devices to be run simultaneously. Measurements are wirelessly transferred to a mobile phone application that geo-tags the data and transmits it to a remote server for real time tracking of micronutrient deficiencies. Clinical tests of micronutrient levels from whole blood samples (n=95) show comparable sensitivity and specificity to ELISA-based tests. These results demonstrate instantaneous acquisition and global aggregation of diagnostics data using a fully integrated point of care system that will enable rapid and distributed surveillance of disease prevalence and geographical progression.

This is a study on sexual violence against women in the Brazilian State of Santa Catarina notified to the Notifiable Diseases Information System (SINAN) in the period 20082013. It aimed to estimate pregnancy and sexually transmitted infections (STIs) resulting from sexual violence and to test the association between pregnancy, STIs and care provided in health services. In total, 1,230 pregnancy notifications and 1.316 STI notifications were analyzed. Variables were age, schooling, time to receive care, STI prophylaxis, emergency contraception, number of perpetrators and recurrent violence, which were analyzed using proportions and 95% confidence intervals. Associations were tested by adjusted and non-adjusted logistic regression with values expressed in odds ratio. The occurrence of pregnancy was 7.6%. Receiving care within 72 hours and emergency contraception were protective factors. The occurrence of STIs was 3.5%. Care within 72 hours and prophylaxis did not result in lower proportions of STIs. Further studies are required regarding this issue.

Point-of-care International Normalised Ratio (INR) testing is used frequently. We evaluated the microINR ® POC system for accuracy, precision and measurement repeatability, and investigated instrument and test chip variability and error rates. Venous blood INRs of 210 patients on warfarin were obtained with Thromborel ® S on the Sysmex CS-2100i ® analyser and compared with capillary blood microINR ® values. Precision was assessed using control materials. Measurement repeatability was calculated on 51 duplicate finger-prick INRs. Triplicate finger-prick INRs using three different instruments (30 patients) and three different test chip lots (29 patients) were used to evaluate instrument and test chip variability. Linear regression analysis of microINR ® and Sysmex CS2100i ® values showed a correlation coefficient of 0.96 (P < .0001) and a positive proportional bias of 4.4%. Dosage concordance was 93.8% and clinical agreement 95.7%. All acceptance criteria based on ISO standard 17593:2007 system accuracy requirements were met. Control material coefficients of variation (CV) varied from 6.2% to 16.7%. The capillary blood measurement repeatability CV was 7.5%. No significant instrument (P = .93) or test chip (P = .81) variability was found, and the error rate was low (2.8%). The microINR ® instrument is accurate and precise for monitoring warfarin therapy. © 2017 John Wiley & Sons Ltd.

The aim of this, the largest survey of patients performed to date, is to analyse the effects of diagnosis related groups (DRGs) on the doctor-patient relationship in the context of interdisciplinary patient-centered care. In addition, it is intended to investigate the possibility of motivating patients to change their behavioural patterns and lifestyle in the context of holistic therapy. Over a period of five years, a continuous survey was performed of hospitalised patients who were exercising their entitlement to interdisciplinary therapy in an acute, inpatient setting. The therapy was evaluated as good to very good both with and without the conditions of the case tariff fee system. Effects of the diagnosis related groups on the quality of the doctor-patient relationship could not be demonstrated (Mann-Whitney U test, p>0,05). A clear trend was evident in the influence on motivation to change behavioural patterns and lifestyle (Fisher's exact test, p=0,000). Studies of the effects of reimbursement systems in the context of interdisciplinary care are still in their infancy, despite the widespread use of diagnosis related groups. The mandatory character implicit in the case tariff fee system, which requires minimum qualitative standards for structural and procedural parameters in the context of providing interdisciplinary patient-centered care, can influence patients' behavioural patterns and lifestyle.

The personal care industry is focused on developing safe, more efficacious, and increasingly milder products, that are routinely undergoing preclinical and clinical testing before becoming available for consumer use on skin. In vitro systems based on skin reconstructed equivalents are now established for the preclinical assessment of product irritation potential and as alternative testing methods to the classic Draize rabbit skin irritation test. We have used the 3-D EpiDerm™ model system to evaluate tissue viability and primary cytokine interleukin-1α release as a way to evaluate the potential dermal irritation of 224 non-ionic, amphoteric and/or anionic surfactant-containing formulations, or individual raw materials. As part of our testing programme, two representative benchmark materials with known clinical skin irritation potential were qualified through repeated testing, for use as references for the skin irritation evaluation of formulations containing new surfactant ingredients. We have established a correlation between the in vitro screening approach and clinical testing, and are continually expanding our database to enhance this correlation. This testing programme integrates the efforts of global manufacturers of personal care products that focus on the development of increasingly milder formulations to be applied to the skin, without the use of animal testing. 2016 FRAME.

To determine the impact of a health system-wide primary care diabetes management system, which included targeted guidelines for type 2 diabetes (T2DM) and prediabetes (dysglycemia) screening, on detection of previously undiagnosed dysglycemia cases. Intervention included electronic health record (EHR)-based decision support and standardized providers and staff training for using the American Diabetes Association guidelines for dysglycemia screening. Using EHR data, we identified 40,456 adults without T2DM or recent screening with a face-to-face visit (March 2011-December 2013) in five urban clinics. Interrupted time series analyses examined the impact of the intervention on trends in three outcomes: 1 ) monthly proportion of eligible patients receiving dysglycemia testing, 2 ) two negative comparison conditions (dysglycemia testing among ineligible patients and cholesterol screening), and 3 ) yield of undiagnosed dysglycemia among those tested. Baseline monthly proportion of eligible patients receiving testing was 7.4-10.4%. After the intervention, screening doubled (mean increase + 11.0% [95% CI 9.0, 13.0], proportion range 18.6-25.3%). The proportion of ineligible patients tested also increased (+5.0% [95% CI 3.0, 8.0]) with no concurrent change in cholesterol testing (+0% [95% CI -0.02, 0.05]). About 59% of test results in eligible patients showed dysglycemia both before and after the intervention. Implementation of a policy for systematic dysglycemia screening including formal training and EHR templates in urban academic primary care clinics resulted in a doubling of appropriate testing and the number of patients who could be targeted for treatment to prevent or delay T2DM. © 2017 by the American Diabetes Association.

Current guidelines recommend that all sexually active human immunodeficiency virus (HIV)-infected persons be tested at least annually for syphilis, chlamydia, and gonorrhea. We examined temporal trends in syphilis, chlamydia, and gonorrhea testing among sexually active HIV-infected adults receiving medical care in the United States during 2009-2013. Using medical record data from the Medical Monitoring Project, a population-based HIV surveillance system, we assessed the proportion of adults receiving HIV medical care who were tested for syphilis, chlamydia, and gonorrhea in the past 12 months by year and stratified by sex and sexual behavior, age, and race/ethnicity. During 2009-2013, the proportion of sexually active HIV-infected adults receiving medical care who were tested in the past year for all 3 examined sexually transmitted diseases (STDs) increased from 20% to 36% (PTREND < .01). Overall testing for syphilis increased from 55% to 65% (PTREND < .01), and significant increases were noted for the following subgroups: men who have sex with men (58% to 69%), non-Hispanic whites (48% to 64%), and all age groups with the exception of persons aged 18-29 year. Overall testing for chlamydia and gonorrhea increased from 22% to 42% (PTREND < .01), and significant increases were noted for most subgroups. STD testing significantly increased among sexually active HIV-infected adults receiving medical care; however, the majority of persons were not tested for all 3 STDs in 2013. While increased testing indicates progress, testing remained far below recommended guidelines. Our findings suggest enhanced efforts may be warranted to screen all sexually active HIV-infected adults for syphilis, chlamydia, and gonorrhea.

The effect of electronic medical records (EMRs) on quality of care in physicians' offices is uncertain. This study used the 2008-2009 National Ambulatory Medical Care Survey to examine the relationship between EMRs features and quality in physician offices. The relationship between selected EMRs features and 7 quality measures was evaluated by testing 25 associations in multivariate models. Significant relationships include reminders for guideline-based interventions or screening tests associated with lower odds of inappropriate urinalysis and prescription of antibiotics for upper respiratory infection (URI), prescription order entry associated with lower odds of prescription of antibiotics for URI, and patient problem list associated with higher odds of inappropriate prescribing for elderly patients. EMRs system level was associated with lower odds of blood pressure check, inappropriate urinalysis, and prescription of antibiotics for URI compared with no EMRs. The results show both positive and inverse relationships between EMRs features and quality of care.

China is reforming the way it finances health care as it moves towards Universal Health Coverage (UHC) after the failure of market-oriented mechanisms for health care. Improving financing equity is a major policy goal of health care system during the progression towards universal coverage. We used progressivity analysis and dominance test to evaluate the financing channels of general taxation, pubic health insurance, and out-of-pocket (OOP) payments. In 2012 a survey of 8854 individuals in 3008 households recorded the socioeconomic and demographic status, and health care payments of those households. The overall Kakwani index (KI) of China's health care financing system is 0.0444. For general tax KI was -0.0241 (95% confidence interval (CI): -0.0315 to -0.0166). The indices for public health schemes (Urban Employee Basic Medical Insurance, Urban Resident's Basic Medical Insurance, New Rural Cooperative Medical Scheme) were respectively 0.1301 (95% CI: 0.1008 to 0.1594), -0.1737 (95% CI: -0.2166 to -0.1308), and -0.5598 (95% CI: -0.5830 to -0.5365); and for OOP payments KI was 0.0896 (95%CI: 0.0345 to 0.1447). OOP payments are still the dominant part of China's health care finance system. China's health care financing system is not really equitable. Reducing the proportion of indirect taxes would considerably improve health care financing equity. The flat-rate contribution mechanism is not recommended for use in public health insurance schemes, and more attention should be given to optimizing benefit packages during China's progression towards UHC.

Providing quality care for all children living with HIV/AIDS remains a global challenge and requires the development of new healthcare delivery strategies. The care delivery value chain (CDVC) is a framework that maps activities required to provide effective and responsive care for a patient with a particular disease across the continuum of care. By mapping activities along a value chain, the CDVC enables managers to better allocate resources, improve communication, and coordinate activities. We report on the successful application of the CDVC as a strategy to optimize care delivery and inform quality improvement (QI) efforts with the overall aim of improving care for Pediatric HIV patients in Togo, West Africa. Over the course of 12 months, 13 distinct QI activities in Pediatric HIV/AIDS care delivery were monitored, and 11 of those activities met or exceeded established targets. Examples included: increase in infants receiving routine polymerase chain reaction testing at 2 months (39-95%), increase in HIV exposed children receiving confirmatory HIV testing at 18 months (67-100%), and increase in patients receiving initial CD4 testing within 3 months of HIV diagnosis (67-100%). The CDVC was an effective approach for evaluating existing systems and prioritizing gaps in delivery for QI over the full cycle of Pediatric HIV/AIDS care in three specific ways: (1) facilitating the first comprehensive mapping of Pediatric HIV/AIDS services, (2) identifying gaps in available services, and (3) catalyzing the creation of a responsive QI plan. The CDVC provided a framework to drive meaningful, strategic action to improve Pediatric HIV care in Togo.

The Centers for Disease Control and Prevention have endorsed the concept of preconception care (PCC). New tools must be developed to promote PCC. Development and testing of a health information technology system to provide PCC. An urban safety net hospital and an urban university. Community recruitment of 31 women in focus groups and 15 women participating in observed usability testing; 9 students recruited from the Office of Minority Health Preconception Peer Educators program participated in pilot testing for 2 months. Online interactive animated character ("Gabby") designed to identify and modify preconception risks. Qualitative transcripts, preconception risk assessment, server data for system usage, self-administered satisfaction surveys, and follow-up phone calls. Descriptive statistics of subjects' demographics, satisfaction, PCC risks, and system usage. Transcripts coded using NVIVO. Subjects (n = 24) reported an average of 23 preconception risks; in the pilot, 83% of risks added to the "My Health To-Do List" were addressed by the subject. Seventy-three percent of risks identified as contemplative progressed to action or maintenance. Differences were noted in effectiveness of the system based on initial stage of change for each risk. Results suggest that the PCC system could be effective in influencing positive behavior change. Adding stage of change-focused functionality might have added benefits. This system has great potential to assist in the delivery of PCC.

Abstract Objective To investigate factors influencing the adoption of kangaroo mother care in different contexts. Methods We searched PubMed, Embase, Scopus, Web of Science and the World Health Organization’s regional databases, for studies on “kangaroo mother care” or “kangaroo care” or “skin-to-skin care” from 1 January 1960 to 19 August 2015, without language restrictions. We included programmatic reports and hand-searched references of published reviews and articles. Two independent reviewers screened articles and extracted data on carers, health system characteristics and contextual factors. We developed a conceptual model to analyse the integration of kangaroo mother care in health systems. Findings We screened 2875 studies and included 112 studies that contained qualitative data on implementation. Kangaroo mother care was applied in different ways in different contexts. The studies show that there are several barriers to implementing kangaroo mother care, including the need for time, social support, medical care and family acceptance. Barriers within health systems included organization, financing and service delivery. In the broad context, cultural norms influenced perceptions and the success of adoption. Conclusion Kangaroo mother care is a complex intervention that is behaviour driven and includes multiple elements. Success of implementation requires high user engagement and stakeholder involvement. Future research includes designing and testing models of specific interventions to improve uptake. PMID:26908962

Creep tests were conducted by means of a closed loop servo-controlled materials test system. These tests are different from the conventional creep tests in that the strain history prior to creep may be carefully monitored. Tests were performed for aluminum alloy 6061-0 at 150 C and monitored by a PDP 11/04 minicomputer at a preset constant plastic-strain rate prehistory. The results show that the plastic-strain rate prior to creep plays a significant role in creep behavior. The endochronic theory of viscoplasticity was applied to describe the observed creep curves. The concepts of intrinsic time and strain rate sensitivity function are employed and modified according to the present observation.

The Biomedical Sciences Program of the University of South Carolina intends to increase the number of qualified, economically disadvantaged minority students graduating from educational programs that lead to careers in the health field. The objective is to provide students with an overview of the health care delivery system in the United States and to acquaint students with a wide range of health care occupations and opportunities in the health care field. Experience-based learning, through site visits to different health care centers, is used in this program.In 1981, 100 ninth-grade students from rural school districts in South Carolina were recruited to participate in the program from 1981 through 1985. To assist in evaluation of the summer program, each student completed a self-administered questionnaire composed of questions related to background information and a pre-test covering factual material derived from information provided by visits to health care delivery agencies. At the completion of the summer program, the same test (excluding the collection of background material) was administered as a post-test.Of the 113 students who took the pre-test, 89 students also took the post-test. The decrease in students was accounted for by early withdrawal from the summer program or conflicts in scheduled events. Of the post-test group, 75 (84.3 percent) were nonwhite and 14 (15.7 percent) were white. The sex distribution was 60 women (67.4 percent) and 29 men (32.6 percent).Follow-up on academic advancement and career development progress is planned for each student over the next five years.

Objective To highlight the unique challenges of evaluative research on practice behavior change in the “real world” settings of contemporary managed-care organizations, using the experience of the Pediatric Asthma Care PORT (Patient Outcomes Research Team). Study Setting The Pediatric Asthma Care PORT is a five-year initiative funded by the Agency for Healthcare Research and Quality to study strategies for asthma care improvement in three managed-care plans in Chicago, Seattle, and Boston. At its core is a randomized trial of two care improvement strategies compared with usual care: (1) a targeted physician education program using practice based Peer Leaders (PL) as change agents, (2) adding to the PL intervention a “Planned Asthma Care Intervention” incorporating joint “asthma check-ups” by nurse-physician teams. During the trial, each of the participating organizations viewed asthma care improvement as an immediate priority and had their own corporate improvement programs underway. Data Collection Investigators at each health plan described the organizational and implementation challenges in conducting the PAC PORT randomized trial. These experiences were reviewed for common themes and “lessons” that might be useful to investigators planning interventional research in similar care-delivery settings. Conclusions Randomized trials in “real world” settings represent the most robust design available to test care improvement strategies. In complex, rapidly changing managed-care organizations, blinding is not feasible, corporate initiatives may complicate implementation, and the assumption that a “usual care” arm will be static is highly likely to be mistaken. Investigators must be prepared to use innovative strategies to maintain the integrity of the study design, including: continuous improvement within the intervention arms, comanagement by researchers and health plan managers of condition-related quality improvement initiatives, procedures for avoiding respondent burden in health plan enrollees, and anticipation and minimization of risks from experimental arm contamination and major organizational change. With attention to these delivery system issues, as well as the usual design features of randomized trials, we believe managed-care organizations can serve as important laboratories to test care improvement strategies.

The channeling demonstration sought to substitute community care for nursing home care to reduce long-term care costs and improve the quality of life of elderly clients and the family members and friends who care for them. Two interventions were tested, each in five sites; both had comprehensive case management at their core. One model added a small amount of additional funding for direct community services to fill the gaps in the existing system; the other substantially expanded coverage of community services regardless of categorical eligibility under existing programs. The demonstration was evaluated using a randomized experimental design to test the effects of channeling on use of community care, nursing homes, hospitals, and informal caregiving, and on measures of the quality of life of clients and their informal caregivers. Data were obtained from interviews with clients and informal caregivers; service use and cost records came from Medicare, Medicaid, channeling, and providers; and death records for an 18-month follow-up period were examined.

Knowledge translation (KT) is an imperative in order to implement research-based and contextualized practices that can answer the numerous challenges of complex health problems. The Chronic Care Model (CCM) provides a conceptual framework to guide the implementation process in chronic care. Yet, organizations aiming to improve chronic care require an adequate level of organizational readiness (OR) for KT. Available instruments on organizational readiness for change (ORC) have shown limited validity, and are not tailored or adapted to specific phases of the knowledge-to-action (KTA) process. We aim to develop an evidence-based, comprehensive, and valid instrument to measure OR for KT in healthcare. The OR for KT instrument will be based on core concepts retrieved from existing literature and validated by a Delphi study. We will specifically test the instrument in chronic care that is of an increasing importance for the health system. Phase one: We will conduct a systematic review of the theories and instruments assessing ORC in healthcare. The retained theoretical information will be synthesized in a conceptual map. A bibliography and database of ORC instruments will be prepared after appraisal of their psychometric properties according to the standards for educational and psychological testing. An online Delphi study will be carried out among decision makers and knowledge users across Canada to assess the importance of these concepts and measures at different steps in the KTA process in chronic care.Phase two: A final OR for KT instrument will be developed and validated both in French and in English and tested in chronic disease management to measure OR for KT regarding the adoption of comprehensive, patient-centered, and system-based CCMs. This study provides a comprehensive synthesis of current knowledge on explanatory models and instruments assessing OR for KT. Moreover, this project aims to create more consensus on the theoretical underpinnings and the instrumentation of OR for KT in chronic care. The final product--a comprehensive and valid OR for KT instrument--will provide the chronic care settings with an instrument to assess their readiness to implement evidence-based chronic care.

This study proposes and tests a systemic family decision-making framework to understand group long-term care insurance (LTCI) enrollment decisions. A random sample of public employees who were offered group LTCI as a workplace benefit were examined. Findings reveal very good predictive efficacy for the overall conceptual framework with a pseudo R2 value of .687, and reinforced the contributions of factors within the family system. Enrollees were more likely to have discussed the decision with others, used information sources, and had prior experience when compared to non-enrollees. Perceived health status, financial knowledge, attitudes regarding the role of private insurance, risk taking, and coverage features were additional factors related to enrollment decisions. The findings help to inform policymakers about the potential of LTCI as one strategy for financing long-term care.

Approximately three million persons in the United States are infected with hepatitis C virus (HCV), a blood-borne pathogen that is an increasing cause of liver disease and mortality in the United States. Treatments for HCV are curative, of short duration, and have few associated side effects, increasing the importance of identifying HCV-infected persons. Many persons with HCV infection were infected decades ago, before implementation of prevention measures and most are unaware of their infection, regardless of when it occurred. Most newly diagnosed cases are associated with injection drug use. Persons born during 1945-1965 have a fivefold higher risk of HCV infection than other adults and the highest risk for HCV-related morbidity and mortality. CDC recommends testing for this group, for persons who inject drugs, and others at risk for HCV infection. From October 2012 through July 2014, the National Nursing Centers Consortium (NNCC) carried out a project to integrate routine HCV testing and linkage-to-care in five federally qualified health centers in Philadelphia, PA, that primarily serve homeless persons and public housing residents. During the project period, 4,514 patients across the five centers were tested for HCV. Of these, 595 (13.2%) were HCV-antibody positive and 550 (92.4%) had a confirmatory HCV-RNA test performed. Of those who had a confirmatory HCV-RNA test performed, 390 (70.9%) were identified as having current (i.e., chronic) HCV infection (overall prevalence = 8.6%). Of those currently infected with HCV, 90% were informed of their status, 78% were referred to an HCV care specialist, and 62% went to the referred specialist for care. Replicable system modifications that improved HCV testing and care included enhancements to electronic medical records (EMRs), simplification of HCV testing protocols, and addition of a linkage-to-care coordinator. Findings from this project highlight the need for innovative strategies for HCV testing, care, and treatment, as well as the important role of community health centers in expanding access for patient populations disproportionately affected by HCV infection.

Urticarial Reactions: Vascular Erythema, Urticaria, Vasculitis

Vascular erythemas, including urticaria and vasculitis, represent diagnostic and therapeutic challenges. A careful systemic approach to history and physical examination should be followed by appropriate investigations to rule out systemic disease. Chronic urticaria patients should be physically tested to identify cholinergic, dermagraphic, and cold-induced responses. Food diaries and careful drug history may be important to identify exacerbating factors in chronic urticaria. A skin biopsy is necessary to diagnose vasculitis. Therapy of any underlying cause is supplemented with H1 antihistamines in urticaria patients, while vasculitis requires a different anti-inflammatory approach. PMID:21263956

In this report, we describe the evolution and types of genetic information provided directly to consumers, discuss potential advantages and disadvantages of these products, and review research evaluating consumer responses to direct-to-consumer (DTC) genetic testing. The available evidence to date has focused on predictive tests and does not suggest that individuals, health care providers, or health care systems have been harmed by a DTC provision of genetic information. An understanding of consumer responses to susceptibility tests has lagged behind. The Multiplex Initiative is presented as a case study of research to understand consumers' responses to DTC susceptibility tests. Three priority areas are recommended for accelerated research activities to inform public policy regarding DTC genetic information: (a) exploring consumer's long-term responses to DTC genetic testing on a comprehensive set of outcomes, (b) evaluating optimal services to support decision making about genetic testing, and (c) evaluating best practices in promoting genetic competencies among health providers.

The Department of Veterans Affairs (VA) has a system-wide, patient-centric electronic medical record system (EMR) within which the authors developed the Clinical Case Registries (CCR) to support population-centric delivery and evaluation of VA medical care. To date, the authors have applied the CCR to populations with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). Local components use diagnosis codes and laboratory test results to identify patients who may have HIV or HCV and support queries on local care delivery with customizable reports. For each patient in a local registry, key EMR data are transferred via HL7 messaging to a single national registry. From 128 local registry systems, over 60,000 and 320,000 veterans in VA care have been identified as having HIV and HCV, respectively, and entered in the national database. Local and national reports covering demographics, resource usage, quality of care metrics and medication safety issues have been generated. PMID:19717794

Integrating two distinct and complementary paradigms, science and engineering, may produce more effective outcomes for the implementation of evidence-based practices in health care settings. Science formalizes and tests innovations, whereas engineering customizes and optimizes how the innovation is applied tailoring to accommodate local conditions. Together they may accelerate the creation of an evidence-based healthcare system that works effectively in specific health care settings. We give examples of applying engineering methods for better quality, more efficient, and safer implementation of clinical practices, medical devices, and health services systems. A specific example was applying systems engineering design that orchestrated people, process, data, decision-making, and communication through a technology application to implement evidence-based depression care among low-income patients with diabetes. We recommend that leading journals recognize the fundamental role of engineering in implementation research, to improve understanding of design elements that create a better fit between program elements and local context.

Invasive blood pressure monitoring is increasing in anesthesia and intensive care. Compared to noninvasive methods, it has some decisive advantages: (1) blood pressure trends can be assessed beat by beat, which is important especially in situations of cardiac arrhythmia; (2) respiratory changes in blood pressure as one sign of hypovolemia can be detected easily; and (3) pressure changes induced by the autonomic nervous system become apparent. We studied a new, reusable pressure transducer system, the Medex Novatrans-MX800 in routine intra- and postoperative monitoring of patients undergoing cardiac surgery using the following criteria: (1) handling; (2) accuracy of measurement; (3) durability; and (4) costs. The system is easy to use and has a low susceptability to breakdown. In 29 of 31 transducers tested, the error of measurement over a range of 0-150 mmHg was less than 2% as reported by the manufacturer. Two transducers showed errors of measurement over 5% after 60 times of reuse. The mean reusability rate until the transducer became defective was 75.8 +/- 17.3 in the operating room (19 transducers tested) and 59.7 +/- 29 in the intensive care unit (12 transducers tested, 11 still in use). A comparison of costs shows that the Novatrans-MX800 system is the cheapest system for invasive pressure monitoring available at this time.

Maternal care has been shown to affect the development of the brain, behaviour, social skills and emotional systems of the young of many mammalian species including dogs. The aim of the present study was to determine the effects of maternal care on the behavioural responses of family dog puppies towards environmental and social stimuli. In order to do this, maternal care (licking puppy's ano-genital area, licking the puppy, nursing and mother-puppy contact) during the first three weeks after birth was assessed in 12 litters of domestic dog puppies reared in home environments (total = 72 puppies). The behavioural responses of puppies were assessed in an arena and an isolation test, which were performed when the puppies were two-month old. Data were analysed using principal components analysis and projection to latent structures regression. A systematic relationship was found between maternal care and behaviour in both tests. In the arena test, maternal care was found to be positively associated with approach to the stranger, attention oriented to the stranger, time spent near the enclosure, yawning, whining and yelping (R²Y = 0.613, p = 8.2 × 10 -9 ). Amount of maternal care was negatively associated with the number of squares crossed and the time spent individually playing with the rope. In the isolation test, the amount of maternal care was positively associated with standing posture, paw lifting, and howling, and it was negatively associated with yawning, lying down and nose licking (R²Y = 0.507, p = 0.000626). These results suggest that the amount of maternal care received during early life influences the pattern of behavioural responses and coping strategies of puppies at two-months of age. On the basis of these findings it could be speculated that early maternal care contributes to adaption to the environment in which family puppies are developing, with particular regard to social relationships with people.

Coordination across levels of care is becoming increasingly important due to rapid advances in technology, high specialisation and changes in the organization of healthcare services; to date, however, the development of indicators to evaluate coordination has been limited. The aim of this study is to develop and test a set of indicators to comprehensively evaluate clinical coordination across levels of care. A systematic review of literature was conducted to identify indicators of clinical coordination across levels of care. These indicators were analysed to identify attributes of coordination and classified accordingly. They were then discussed within an expert team and adapted or newly developed, and their relevance, scientific soundness and feasibility were examined. The indicators were tested in three healthcare areas of the Catalan health system. 52 indicators were identified addressing 11 attributes of clinical coordination across levels of care. The final set consisted of 21 output indicators. Clinical information transfer is evaluated based on information flow (4) and the adequacy of shared information (3). Clinical management coordination indicators evaluate care coherence through diagnostic testing (2) and medication (1), provision of care at the most appropriate level (2), completion of diagnostic process (1), follow-up after hospital discharge (4) and accessibility across levels of care (4). The application of indicators showed differences in the degree of clinical coordination depending on the attribute and area. A set of rigorous and scientifically sound measures of clinical coordination across levels of care were developed based on a literature review and discussion with experts. This set of indicators comprehensively address the different attributes of clinical coordination in main transitions across levels of care. It could be employed to identify areas in which health services can be improved, as well as to measure the effect of efforts to improve clinical coordination in healthcare organizations.

A Colorimetric Enzyme-Linked Immunosorbent Assay (ELISA) Detection Platform for a Point-of-Care Dengue Detection System on a Lab-on-Compact-Disc

The enzyme-linked Immunosorbent Assay (ELISA) is the gold standard clinical diagnostic tool for the detection and quantification of protein biomarkers. However, conventional ELISA tests have drawbacks in their requirement of time, expensive equipment and expertise for operation. Hence, for the purpose of rapid, high throughput screening and point-of-care diagnosis, researchers are miniaturizing sandwich ELISA procedures on Lab-on-a-Chip and Lab-on-Compact Disc (LOCD) platforms. This paper presents a novel integrated device to detect and interpret the ELISA test results on a LOCD platform. The system applies absorption spectrophotometry to measure the absorbance (optical density) of the sample using a monochromatic light source and optical sensor. The device performs automated analysis of the results and presents absorbance values and diagnostic test results via a graphical display or via Bluetooth to a smartphone platform which also acts as controller of the device. The efficacy of the device was evaluated by performing dengue antibody IgG ELISA on 64 hospitalized patients suspected of dengue. The results demonstrate high accuracy of the device, with 95% sensitivity and 100% specificity in detection when compared with gold standard commercial ELISA microplate readers. This sensor platform represents a significant step towards establishing ELISA as a rapid, inexpensive and automatic testing method for the purpose of point-of-care-testing (POCT) in resource-limited settings.

Introduction Achieving the Joint United Nations Programme on HIV and AIDS 90-90-90 targets requires models of HIV care that expand antiretroviral therapy (ART) coverage without overburdening health systems. Point-of-care (POC) viral load (VL) testing has the potential to efficiently monitor ART treatment, while enrolled nurses may be able to provide safe and cost-effective chronic care for stable patients with HIV. This study aims to demonstrate whether POC VL testing combined with task shifting to enrolled nurses is non-inferior and cost-effective compared with laboratory-based VL monitoring and standard HIV care. Methods and analysis The STREAM (Simplifying HIV TREAtment and Monitoring) study is an open-label, non-inferiority, randomised controlled implementation trial. HIV-positive adults, clinically stable at 6 months after ART initiation, will be recruited in a large urban clinic in South Africa. Approximately 396 participants will be randomised 1:1 to receive POC HIV VL monitoring and potential task shifting to enrolled nurses, versus laboratory VL monitoring and standard South African HIV care. Initial clinic follow-up will be 2-monthly in both arms, with VL testing at enrolment, 6 months and 12 months. At 6 months (1 year after ART initiation), stable participants in both arms will qualify for a differentiated care model involving decentralised ART pickup at community-based pharmacies. The primary outcome is retention in care and virological suppression at 12 months from enrolment. Secondary outcomes include time to appropriate entry into the decentralised ART delivery programme, costs per virologically suppressed patient and cost-effectiveness of the intervention compared with standard care. Findings will inform the scale up of VL testing and differentiated care in HIV-endemic resource-limited settings. Ethics and dissemination Ethical approval has been granted by the University of KwaZulu-Natal Biomedical Research Ethics Committee (BFC296/16) and University of Washington Institutional Review Board (STUDY00001466). Results will be presented at international conferences and published in academic peer-reviewed journals. Trial registration NCT03066128; Pre-results. PMID:28963304

Background Home care patients often use many medications and are prone to drug-related problems (DRPs). For the management of problems related to drug use, home care could add to the multidisciplinary expertise of general practitioners (GPs) and pharmacists. The home care observation of medication-related problems by home care employees (HOME)-instrument is paper-based and assists home care workers in reporting potential DRPs. To facilitate the multiprofessional consultation, a digital report of DRPs from the HOME-instrument and digital monitoring and consulting of DRPs between home care and general practices and pharmacies is desired. Objective The objective of this study was to develop an electronic HOME system (eHOME), a mobile version of the HOME-instrument that includes a monitoring and a consulting system for primary care. Methods The development phase of the Medical Research Council (MRC) framework was followed in which an iterative human-centered design (HCD) approach was applied. The approach involved a Delphi round for the context of use and user requirements analysis of the digital HOME-instrument and the monitoring and consulting system followed by 2 series of pilots for testing the usability and redesign. Results By using an iterative design approach and by involving home care workers, GPs, and pharmacists throughout the process as informants, design partners, and testers, important aspects that were crucial for system realization and user acceptance were revealed. Through the report webpage interface, which includes the adjusted content of the HOME-instrument and added home care practice–based problems, home care workers can digitally report observed DRPs. Furthermore, it was found that the monitoring and consulting webpage interfaces enable digital consultation between home care and general practices and pharmacies. The webpages were considered convenient, clear, easy, and usable. Conclusions By employing an HCD approach, the eHOME-instrument was found to be an easy-to-use system. The systematic approach promises a valuable contribution for the future development of digital mobile systems of paper-based tools. PMID:29514771

Background Screening for fecal occult blood can be effective in reducing colorectal cancer mortality only if positive tests are appropriately followed up with complete diagnostic evaluation (i.e., colonoscopy or flexible sigmoidoscopy with double contrast barium enema) and treatment. Objectives To examine whether rates of complete diagnostic evaluation following a positive fecal occult blood test (FOBT) have improved over time after the implementation of tracking systems and physician guidelines within a large integrated health care organization. Research Design From 1993 to 2005, 8513 positive FOBTs were identified on 8291 enrollees aged 50–79 of a large health care system. Automated records were used to identify repeat FOBTs, colonoscopy, flexible sigmoidoscopy, and double-contrast barium enema within one year after the positive FOBT. National rates of complete diagnostic evaluation were estimated from the 2005 National Health Interview Survey. Results In this integrated health care organization, the percentage of positive FOBTs followed by complete diagnostic evaluation within one year increased from 57%–64% in 1993–1996 to 82%–86% from 2000–2005. Use of repeat FOBT following a positive FOBT decreased from 28–31% in 1993–1996 to 6–11% in 2000–2005. Based on the National Health Interview Survey, only 52% of positive FOBTs from 2000–2005 were followed by complete diagnostic evaluation nationally. Conclusions Adherence to recommendations for complete diagnostic evaluation following a positive FOBT has greatly improved over time in an integrated group medical practice. Through the use of tracking systems and screening guidelines, it may be possible to reach levels of follow-up that are comparable to those observed in randomized trials. PMID:18725839

Understanding of cancer outcomes is limited by data fragmentation. In the current study, the authors analyzed the information yielded by integrating breast cancer data from 3 sources: electronic medical records (EMRs) from 2 health care systems and the state registry. Diagnostic test and treatment data were extracted from the EMRs of all patients with breast cancer treated between 2000 and 2010 in 2 independent California institutions: a community-based practice (Palo Alto Medical Foundation; "Community") and an academic medical center (Stanford University; "University"). The authors incorporated records from the population-based California Cancer Registry and then linked EMR-California Cancer Registry data sets of Community and University patients. The authors initially identified 8210 University patients and 5770 Community patients; linked data sets revealed a 16% patient overlap, yielding 12,109 unique patients. The percentage of all Community patients, but not University patients, treated at both institutions increased with worsening cancer prognostic factors. Before linking the data sets, Community patients appeared to receive less intervention than University patients (mastectomy: 37.6% vs 43.2%; chemotherapy: 35% vs 41.7%; magnetic resonance imaging: 10% vs 29.3%; and genetic testing: 2.5% vs 9.2%). Linked Community and University data sets revealed that patients treated at both institutions received substantially more interventions (mastectomy: 55.8%; chemotherapy: 47.2%; magnetic resonance imaging: 38.9%; and genetic testing: 10.9% [P < .001 for each 3-way institutional comparison]). Data linkage identified 16% of patients who were treated in 2 health care systems and who, despite comparable prognostic factors, received far more intensive treatment than others. By integrating complementary data from EMRs and population-based registries, a more comprehensive understanding of breast cancer care and factors that drive treatment use was obtained. © 2013 American Cancer Society.

Balance in humans is a motor skill based on complex multimodal sensing, processing and control. Ability to maintain balance in activities of daily living (ADL) is compromised due to aging, diseases, injuries and environmental factors. Center for Disease Control and Prevention (CDC) estimate of the costs of falls among older adults was $34 billion in 2013 and is expected to reach $54.9 billion in 2020. In this paper, we present a brief review of balance impairments followed by subjective and objective tools currently used in clinical settings for human balance assessment. We propose a novel computer vision (CV) based approach as a candidate for functional balance test. The test will take less than a minute to administer and expected to be objective, repeatable and highly discriminative in quantifying ability to maintain posture and balance. We present an informal study with preliminary data from 10 healthy volunteers, and compare performance with a balance assessment system called BTrackS Balance Assessment Board. Our results show high degree of correlation with BTrackS. The proposed system promises to be a good candidate for objective functional balance tests and warrants further investigations to assess validity in clinical settings, including acute care, long term care and assisted living care facilities. Our long term goals include non-intrusive approaches to assess balance competence during ADL in independent living environments.

Objective To assess the quality of medical care in childhood-onset systemic lupus erythematosus (cSLE) at tertiary pediatric rheumatology centers as measured by observance cSLE quality indicators (cSLE-QI). Methods International consensus has been achieved for cSLE-QI (Hollander et al. Arthritis Care & Research, 2013) capturing medical care provision in nine domains: diagnostic testing, education of cardiovascular (CV) risk and lifestyles, lupus nephritis (LN), medication management, bone health, ophthalmological surveillance, transition, pregnancy and vaccination. Using medical record information, the level of performance these cSLE-QI was assessed in cSLE populations treated at four tertiary pediatric rheumatology centers in the U.S, two in Brazil, and one center in India. Results A total of 483 cSLE patients were assessed. Care for the 310 U.S. patients differed markedly for cSLE-QI addressing LN, bone health, vaccinations, education on CV risk, and transition planning. Performance of safety blood testing for medications was high at all centers. Despite often similar performance on the cSLE-QI, access to kidney biopsies was lower in Brazil than in the U.S. Irrespective of country of practice, larger centers tended to meet the cSLE-QI more often than smaller centers. Conclusions The cSLE-QI, evidence based minimum standards of medical care, are not consistently met in the U.S. or some other countries outside the U.S. This has the potential to contribute to suboptimal cSLE outcomes.

Background HIV self-testing (HIVST) offers an opportunity to increase HIV testing among people not reached by facility-based services. However, the promotion of HIVST is limited due to insufficient community engagement. We built a Social Entrepreneurship Model (SET) to promote HIVST linkage to care among Chinese MSM in Guangzhou. Method SET model includes a few key steps: Each participant first completed an online survey, and paid a $23 USD (refundable) deposit to get a HIVST kit and a syphilis self-testing (SST) kit. After the testing, the results were sent to the platform by the participants and interpreted by CDC staff. Meanwhile, the deposit was returned to each participant. Finally, the CBO contacted the participants to provide counseling services, confirmation testing and linkage to care. Result During April–June of 2015, a total of 198 MSM completed a preliminary survey and purchased self-testing kits. Among them, the majority were aged under 34 (84.4%) and met partners online (93.1%). In addition, 68.9% of participants ever tested for HIV, and 19.5% had ever performed HIVST. Overall, feedback was received from 192 (97.0%) participants. Among these, 14 people did not use kits, and the HIV and syphilis prevalence among these users were of 4.5% (8/178) and 3.7% (6/178), respectively. All of the screened HIV-positive cases sought further confirmation testing and were linked to care. Conclusion Using an online SET model to promote HIV and syphilis among Chinese MSM is acceptable and feasible, and this model adds a new testing platform to the current testing service system.

Poor continuity of care may contribute to high health care spending and adverse patient outcomes in dementia. To examine the association between medical clinician continuity and health care utilization, testing, and spending in older adults with dementia. This was a study of an observational retrospective cohort from the 2012 national sample in fee-for-service Medicare, conducted from July to December 2015, using inverse probability weighted analysis. A total of 1 416 369 continuously enrolled, community-dwelling, fee-for-service Medicare beneficiaries 65 years or older with a claims-based dementia diagnosis and at least 4 ambulatory visits in 2012 were included. Continuity of care score measured on patient visits across physicians over 12 months. A higher continuity score is assigned to visit patterns in which a larger share of the patient's total visits are with fewer clinicians. Score range from 0 to 1 was examined in low-, medium-, and high-continuity tertiles. Outcomes include all-cause hospitalization, ambulatory care sensitive condition hospitalization, emergency department visit, imaging, and laboratory testing (computed tomographic [CT] scan of the head, chest radiography, urinalysis, and urine culture), and health care spending (overall, hospital and skilled nursing facility, and physician). Beneficiaries with dementia who had lower levels of continuity of care were younger, had a higher income, and had more comorbid medical conditions. Almost 50% of patients had at least 1 hospitalization and emergency department visit during the year. Utilization was lower with increasing level of continuity. Specifically comparing the highest- vs lowest-continuity groups, annual rates per beneficiary of hospitalization (0.83 vs 0.88), emergency department visits (0.84 vs 0.99), CT scan of the head (0.71 vs 0.83), urinalysis (0.72 vs 1.09), and health care spending (total spending, $22 004 vs $24 371) were higher with lower continuity even after accounting for sociodemographic factors and comorbidity burden (P < .001 for all comparisons). The rate of ambulatory care sensitive condition hospitalization was similar across continuity groups. Among older fee-for-service Medicare beneficiaries with a dementia diagnosis, lower continuity of care is associated with higher rates of hospitalization, emergency department visits, testing, and health care spending. Further research into these relationships, including potentially relevant clinical, clinician, and systems factors, can inform whether improving continuity of care in this population may benefit patients and the wider health system.

ISO (the International Organization for Standardization) is a worldwide federation of national standard bodies (ISO member bodies). The work of preparing international standards is normally carried out through ISO technical committees. ISO 15189 was prepared by Technical Committee ISO/TC 212, clinical laboratory testing, and in vitro diagnostic test systems. This third edition replaces the second edition (ISO 15189:2007), which was technically revised. Medical laboratory services are essential for patient care and, therefore, have to be available to meet the needs of all patients and the clinical personnel responsible for the care of those patients.

With accurate molecular tests now available for diagnosis of chlamydia and gonorrhoea (Chlamydia trachomatis (CT)/Neisseria gonorrhoeae (NG)) at the point-of-care (POC), we aimed to explore the public health implications (benefits and barriers) of their integration into remote primary care in Australia. Qualitative interviews were conducted with a purposively selected group of 18 key informants reflecting sexual health, primary care, remote Aboriginal health and laboratory expertise. Participants believed that POC testing may decrease community prevalence of sexually transmitted infections (STIs), and associated morbidity by reducing the time to treatment and infectious period and expediting partner notification. Also, POC testing could improve acceptability of STI testing, increase testing coverage and result in more targeted prescribing, thereby minimising the risk of antibiotic resistance. Conversely, some felt the immediacy of diagnosis could deter certain young people from being tested. Participants also noted that POC testing may reduce the completeness of communicable disease surveillance data given the current dependence on reporting from pathology laboratories. Others expressed concern about the need to maintain and improve the flow of NG antibiotic sensitivity data, already compromised by the shift to nucleic acid-based testing. This is particularly relevant to remote areas where culture viability is problematic. Results indicate a high level of support from clinicians and public health practitioners for wider access to CT/NG POC tests citing potential benefits, including earlier, more accurate treatment decisions and reductions in ongoing transmission. However, the data also highlight the need for new systems to avoid adverse impact on disease surveillance. Australian and New Zealand Clinical Trials Registry: ACTRN12613000808741.

1987-01-01

Because of the considerable cost of an interactive multispectral image processing system, an evaluation of a prospective system should be performed to ascertain if it will be acceptable to the anticipated users. Evaluation of a developmental system indicated that the important system elements include documentation, user friendliness, image processing capabilities, and system services. The criteria and evaluation procedures for these elements are described herein. The following factors contributed to the success of the evaluation of the developmental system: (1) careful review of documentation prior to program development, (2) construction and testing of macromodules representing typical processing scenarios, (3) availability of other image processing systems for referral and verification, and (4) use of testing personnel with an applications perspective and experience with other systems. This evaluation was done in addition to and independently of program testing by the software developers of the system.

Mobile phone screens can facilitate stimulation to various components of the visual system and many mobile apps are accepted as a means of providing clinical assessments for the oculo-visual system. Although many of these apps are intended for use in clinical settings, there is a growing number of apps in eye care developed for self-tests and eye exercises for lay people. These and other features, however, have not yet been well described. Our objective was to identify, describe, and categorize mobile apps related to eye care that are available to users in the Canadian iTunes market. We conducted an extensive search of the Apple iTunes Store for apps related to eye care. We used the terms "eye," "eye care," "vision," and "eye test" and included apps that are targeted at both lay people and medical professionals. We excluded apps whose primary function is not related to eye care. Eligible apps were categorized by primary purpose, based on how they were described by their developers in the iTunes Store. Our search yielded 10,657 apps, of which 427 met our inclusion criteria. After removing duplicates, 355 unique apps were subject to further review. We assigned the eligible apps to three distinct categories: 39/355 apps (11.0%) were intended for use by medical professionals, 236 apps (66.5%, 236/355) were intended for use by lay people, and 80 apps (22.5%, 80/355) were intended for marketing eye care and eye-care products. We identified 9 subcategories of apps based on the descriptions of their primary functions. Apps for medical professionals fell into three subcategories: clinical calculators (n=6), clinical diagnostic tools (n=18), and education and networking apps for professionals (n=15). Apps for lay people fell into four subcategories: self-testing (n=153), eye exercises (n=30), patient tools and low vision aids (n=35), and apps for patient education (n=18). Mixed-use apps (n=80) were placed into two subcategories: marketing of individual practitioners or eye-care products (n=72) and marketing of multiple eye-care products or professional services. The most extensive subcategory pertaining to eye care consisted of apps for use by lay people, especially for conducting self-tests (n=236). This study revealed a previously uncharacterized category of apps intended for use by doctors and patients, of which the primary goal is marketing of eye-care services and products (n=80). ©Alexander Rodin, Aviv Shachak, Aaron Miller, Vladimir Akopyan, Nataliya Semenova.

Evaluation of features to support safety and quality in general practice clinical software

PubMed Central

2011-01-01

Background Electronic prescribing is now the norm in many countries. We wished to find out if clinical software systems used by general practitioners in Australia include features (functional capabilities and other characteristics) that facilitate improved patient safety and care, with a focus on quality use of medicines. Methods Seven clinical software systems used in general practice were evaluated. Fifty software features that were previously rated as likely to have a high impact on safety and/or quality of care in general practice were tested and are reported here. Results The range of results for the implementation of 50 features across the 7 clinical software systems was as follows: 17-31 features (34-62%) were fully implemented, 9-13 (18-26%) partially implemented, and 9-20 (18-40%) not implemented. Key findings included: Access to evidence based drug and therapeutic information was limited. Decision support for prescribing was available but varied markedly between systems. During prescribing there was potential for medicine mis-selection in some systems, and linking a medicine with its indication was optional. The definition of 'current medicines' versus 'past medicines' was not always clear. There were limited resources for patients, and some medicines lists for patients were suboptimal. Results were provided to the software vendors, who were keen to improve their systems. Conclusions The clinical systems tested lack some of the features expected to support patient safety and quality of care. Standards and certification for clinical software would ensure that safety features are present and that there is a minimum level of clinical functionality that clinicians could expect to find in any system.

Background HIV self-testing allows HIV testing at any place and time and without health workers. HIV self-testing may thus be particularly useful for female sex workers (FSWs), who should test frequently but face stigma and financial and time barriers when accessing healthcare facilities. Methods and findings We conducted a cluster-randomized controlled health systems trial among FSWs in Kampala, Uganda, to measure the effect of 2 HIV self-testing delivery models on HIV testing and linkage to care outcomes. FSW peer educator groups (1 peer educator and 8 participants) were randomized to either (1) direct provision of HIV self-tests, (2) provision of coupons for free collection of HIV self-tests in a healthcare facility, or (3) standard of care HIV testing. We randomized 960 participants in 120 peer educator groups from October 18, 2016, to November 16, 2016. Participants’ median age was 28 years (IQR 24–32). Our prespecified primary outcomes were self-report of any HIV testing at 1 month and at 4 months; our prespecified secondary outcomes were self-report of HIV self-test use, seeking HIV-related medical care and ART initiation. In addition, we analyzed 2 secondary outcomes that were not prespecified: self-report of repeat HIV testing—to understand the intervention effects on frequent testing—and self-reported facility-based testing—to quantify substitution effects. Participants in the direct provision arm were significantly more likely to have tested for HIV than those in the standard of care arm, both at 1 month (risk ratio [RR] 1.33, 95% CI 1.17–1.51, p < 0.001) and at 4 months (RR 1.14, 95% CI 1.07–1.22, p < 0.001). Participants in the direct provision arm were also significantly more likely to have tested for HIV than those in the facility collection arm, both at 1 month (RR 1.18, 95% CI 1.07–1.31, p = 0.001) and at 4 months (RR 1.03, 95% CI 1.01–1.05, p = 0.02). At 1 month, fewer participants in the intervention arms had sought medical care for HIV than in the standard of care arm, but these differences were not significant and were reduced in magnitude at 4 months. There were no statistically significant differences in ART initiation across study arms. At 4 months, participants in the direct provision arm were significantly more likely to have tested twice for HIV than those in the standard of care arm (RR 1.51, 95% CI 1.29–1.77, p < 0.001) and those in the facility collection arm (RR 1.22, 95% CI 1.08–1.37, p = 0.001). Participants in the HIV self-testing arms almost completely replaced facility-based testing with self-testing. Two adverse events related to HIV self-testing were reported: interpersonal violence and mental distress. Study limitations included self-reported outcomes and limited generalizability beyond FSWs in similar settings. Conclusions In this study, HIV self-testing appeared to be safe and increased recent and repeat HIV testing among FSWs. We found that direct provision of HIV self-tests was significantly more effective in increasing HIV testing among FSWs than passively offering HIV self-tests for collection in healthcare facilities. HIV self-testing could play an important role in supporting HIV interventions that require frequent HIV testing, such as HIV treatment as prevention, behavior change for transmission reduction, and pre-exposure prophylaxis.

2011-06-01

We successfully created and implemented an effective HIV rapid testing training and certification curriculum using traditional in-person training at multiple sites within the U.S. Department of Veterans Affairs (VA) Healthcare System. Considering the multitude of geographically remote facilities in the nationwide VA system, coupled with the expansion of HIV diagnostics, we developed an alternate training method that is affordable, efficient, and effective. Using materials initially developed for in-person HIV rapid test in-services, we used a distance learning model to offer this training via live audiovisual online technology to educate clinicians at a remote outpatient primary care VA facility. Participants' evaluation metrics showed that this form of remote education is equivalent to in-person training; additionally, HIV testing rates increased considerably in the months following this intervention. Although there is a one-time setup cost associated with this remote training protocol, there is potential cost savings associated with the point-of-care nurse manager's time productivity by using the Internet in-service learning module for teaching HIV rapid testing. If additional in-service training modules are developed into Internet-based format, there is the potential for additional cost savings. Our cost analysis demonstrates that the remote in-service method provides a more affordable and efficient alternative compared with in-person training. The online in-service provided training that was equivalent to in-person sessions based on first-hand supervisor observation, participant satisfaction surveys, and follow-up results. This method saves time and money, requires fewer personnel, and affords access to expert trainers regardless of geographic location. Further, it is generalizable to training beyond HIV rapid testing. Based on these consistent implementation successes, we plan to expand use of online training to include remote VA satellite facilities spanning several states for a variety of diagnostic devices. Ultimately, Internet-based training has the potential to provide "big city" quality of care to patients at remote (rural) clinics.

U.S. military ground forces report high rates of war-related traumatic stressors, posttraumatic stress disorder (PTSD), and depression following deployment in support of recent armed conflicts in Iraq and Afghanistan. Affected service members do not receive needed mental health services in most cases, and they frequently report stigma and significant structural barriers to mental health services. Improvements in primary care may help address these issues, and evidence supports the effectiveness of a systems-level collaborative care approach. To test the feasibility of systems-level collaborative care for PTSD and depression in military primary care. We named our collaborative care model "Re-Engineering Systems of Primary Care for PTSD and Depression in the Military" (RESPECT-Mil). Key elements of RESPECT-Mil care include universal primary care screening for PTSD and depression, brief standardized primary care diagnostic assessment for those who screen positive, and use of a nurse "care facilitator" to ensure continuity of care for those with unmet depression and PTSD treatment needs. The care facilitator assists primary care providers with follow-up, symptom monitoring, and treatment adjustment and enhances the primary care interface with specialty mental health services. We report assessments of feasibility of RESPECT-Mil implementation in a busy primary care clinic supporting Army units undergoing frequent Iraq, Afghanistan, and other deployments. Thirty primary care providers (family physicians, physician assistants, and nurse practitioners) were trained in the model and in the care of depression and PTSD. The clinic screened 4,159 primary care active duty patient visits: 404 screens (9.7%) were positive for depression, PTSD, or both. Sixty-nine patients participated in collaborative care for 6 weeks or longer, and the majority of these patients experienced clinically important improvement in PTSD and depression. Even although RESPECT-Mil participation was voluntary for providers, only one refused participation. No serious adverse events were noted. Collaborative care is an evidence-based approach to improving the quality of primary care treatment of anxiety and depression. Our version of collaborative care for PTSD and depression, RESPECT-Mil, is feasible, safe, and acceptable to military primary care providers and patients, and participating patients frequently showed clinical improvements. Efforts to implement and evaluate collaborative care approaches for mental disorders in populations at high risk for psychiatric complications of military service are warranted.

A nursing record focused on sexual health care for patients with cancer could encourage oncology nurses to provide sexual health care for oncology patients in a simple and effective manner. However, existing electronic information systems focus on professional use and not sexual health care, which could lead to inefficiencies in clinical practice. To examine the effects of a sexual health care nursing record on the attitudes and practice of oncology nurses. Twenty-four full-time registered nurses caring for oncology patients were randomly assigned to the intervention and control groups in Korea. The researchers developed a sexual health care record and applied it to the intervention group for one month. Data were analyzed by Mann-Whitney U test and chi-square test. Content analysis was used to analyze interviews. Oncology nurses using the sexual health care record had significantly higher levels of sexual health care practice at 4 weeks post-intervention as compared to those who provided usual care to patients with cancer. A sexual health care record may have the potential to facilitate oncology nurses' practice of sexual health care. This study highlighted the importance of using SHC records with oncology patients to improve nursing practice related to sexuality issues. A nursing record focused on SHC for patients with cancer could make it easier and more effective for oncology nurses to provide such care to their patients. Copyright © 2016 Elsevier B.V.

Risk-reducing surgeries are a feasible option for mitigating the risk in individuals with inherited susceptibility to cancer, but are the procedures cost-effective in the current health-care system in Germany? This study compared the health-care costs for bilateral risk-reducing mastectomy (BRRM) and risk-reducing (bilateral) salpingo-oophorectomy (RRSO) with cancer treatment costs that could potentially be prevented. The analysis is based on interdisciplinary consultations with individuals with a high familial risk for breast and ovarian cancer at the University Breast Center for Franconia (Germany) between 2009 and 2013 (370 consultations; 44 patients with BRCA1 mutations and 26 with BRCA2 mutations). Health-care costs for risk-reducing surgeries in BRCA mutation carriers were calculated as reimbursements in the German diagnosis-related groups (DRG) hospital pricing system. These costs for the health-care system were compared with the potential cancer treatment costs that could possibly be prevented by risk-reducing surgeries. Long-term health-care costs can be reduced by risk-reducing surgeries after genetic testing in BRCA mutation carriers. The health-care system in Germany would have saved € 136,295 if BRRM had been performed and € 791,653 if RRSO had been performed before the development of cancer in only 50% of the 70 mutation carriers seen in our center. Moreover, in patients with combined RRSO and BRRM (without breast reconstruction), one further life-year for a 40-year-old BRCA mutation carrier would cost € 2,183. Intensive care, including risk-reducing surgeries in BRCA mutation carriers, is cost-effective from the point of view of the health-care system in Germany. Copyright © 2017 Elsevier Ltd.

Pigmented skin lesions or 'moles' are a common presenting problem in general practice consultations: while the majority are benign, a minority are malignant melanomas. The MoleMate system is a novel diagnostic tool which incorporates spectrophotometric intracutaneous analysis (SIAscopy) within a non-invasive scanning technique and utilises a diagnostic algorithm specifically developed for use in primary care. The MoleMate training program is a short, computer-based course developed to train primary care practitioners to operate the MoleMate diagnostic tool. This pre-trial study used mixed methods to assess the effectiveness and acceptability of a computer-based training program CD-ROM, developed to teach primary care practitioners to identify the seven features of suspicious pigmented lesions (SPLs) seen with the MoleMate system. Twenty-five practitioners worked through the MoleMate training program: data on feature recognition and time taken to conduct the assessment of each lesion were collected. Acceptability of the training program and the MoleMate system in general was assessed by questionnaire. The MoleMate training program improved users' feature recognition by 10% (pre-test median 73.8%, p<0.001), and reduced the time taken to complete assessment of 30 SPLs (pre-test median 21 minutes 53 seconds, median improvement 3 minutes 17 seconds, p<0.001). All practitioners' feature recognition improved (21/21), with most also improving their time (18/21). Practitioners rated the training program as effective and easy to use. The MoleMate training program is a potentially effective and acceptable informatics tool to teach practitioners to recognise the features of SPLs identified by the MoleMate system. It will be used as part of the intervention in a randomised controlled trial to compare the diagnostic accuracy and appropriate referral rates of practitioners using the MoleMate system with best practice in primary care.

Interprofessional team-based care is increasingly regarded as an important feature of delivery systems redesigned to provide more efficient and higher quality care, including primary care. Measurement of the functioning of such teams might enable improvement of team effectiveness and could facilitate research on team-based primary care. Our aims were to develop a conceptual framework of high-functioning primary care teams to identify and review instruments that measure the constructs identified in the framework, and to create a searchable, web-based atlas of such instruments (available at: http://primarycaremeasures.ahrq.gov/team-based-care/ ). Our conceptual framework was developed from existing frameworks, the teamwork literature, and expert input. The framework is based on an Input-Mediator-Output model and includes 12 constructs to which we mapped both instruments as a whole, and individual instrument items. Instruments were also reviewed for relevance to measuring team-based care, and characterized. Instruments were identified from peer-reviewed and grey literature, measure databases, and expert input. From nearly 200 instruments initially identified, we found 48 to be relevant to measuring team-based primary care. The majority of instruments were surveys (n = 44), and the remainder (n = 4) were observational checklists. Most instruments had been developed/tested in healthcare settings (n = 30) and addressed multiple constructs, most commonly communication (n = 42), heedful interrelating (n = 42), respectful interactions (n = 40), and shared explicit goals (n = 37). The majority of instruments had some reliability testing (n = 39) and over half included validity testing (n = 29). Currently available instruments offer promise to researchers and practitioners to assess teams' performance, but additional work is needed to adapt these instruments for primary care settings.

Family-centred HIV care models have emerged as an approach to better target children and their caregivers for HIV testing and care, and further provide integrated health services for the family unit's range of care needs. While there is significant international interest in family-centred approaches, there is a dearth of research on operational experiences in implementation and scale-up. Our retrospective case study examined best practices and enabling factors during scale-up of family-centred care in ten health facilities and ten community clinics supported by a non-governmental organization, Mildmay, in Central Uganda. Methods included key informant interviews with programme management and families, and a desk review of hospital management information systems (HMIS) uptake data. In the 84 months following the scale-up of the family-centred approach in HIV care, Mildmay experienced a 50-fold increase of family units registered in HIV care, a 40-fold increase of children enrolled in HIV care, and nearly universal coverage of paediatric cotrimoxazole prophylaxis. The Mildmay experience emphasizes the importance of streamlining care to maximize paediatric capture. This includes integrated service provision, incentivizing care-seeking as a family, creating child-friendly service environments, and minimizing missed paediatric testing opportunities by institutionalizing early infant diagnosis and provider-initiated testing and counselling. Task-shifting towards nurse-led clinics with community outreach support enabled rapid scale-up, as did an active management structure that allowed for real-time review and corrective action. The Mildmay experience suggests that family-centred approaches are operationally feasible, produce strong coverage outcomes, and can be well-managed during rapid scale-up.

[Primary care in France].

PubMed

Sánchez-Sagrado, T

2016-01-01

The poor planning of health care professionals in Spain has led to an exodus of doctors leaving the country. France is one of the chosen countries for Spanish doctors to develop their professional career. The French health care system belongs to the Bismarck model. In this model, health care system is financed jointly by workers and employers through payroll deduction. The right to health care is linked to the job, and provision of services is done by sickness-funds controlled by the Government. Primary care in France is quite different from Spanish primary care. General practitioners are independent workers who have the right to set up a practice anywhere in France. This lack of regulation has generated a great problem of "medical desertification" with problems of health care access and inequalities in health. French doctors do not want to work in rural areas or outside cities because "they are not value for money". Medical salary is linked to professional activity. The role of doctors is to give punctual care. Team work team does not exist, and coordination between primary and secondary care is lacking. Access to diagnostic tests, hospitals and specialists is unlimited. Duplicity of services, adverse events and inefficiencies are the norm. Patients can freely choose their doctor, and they have a co-payment for visits and hospital care settings. Two years training is required to become a general practitioner. After that, continuing medical education is compulsory, but it is not regulated. Although the French medical Health System was named by the WHO in 2000 as the best health care system in the world, is it not that good. While primary care in Spain has room for improvement, there is a long way for France to be like Spain. Copyright © 2015 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

In the Community of Madrid there is 42.7% late HIV diagnosis. Primary care is the gateway to the health system and the frequency of serological tests requested by these professionals is unknown. The objectives were to establish the frequency of requests for HIV serology by medical and nursing primary care professionals in the Community of Madrid and the factors associated with these requests. An 'on-line' survey was conducted, asking professionals who participated in the evaluation study of strategies to promote early diagnosis of HIV in primary care in the Community of Madrid (ESTVIH) about the number of HIV-serology tests requested in the last 12 months. The association between HIV-serology requesting and the sociodemographic and clinical practice characteristics of the professionals was quantified using adjusted odds ratios (aOR) according to logistic regression. 264 surveys (59.5% physicians). Eighty-two point two percent of medical and 18.7% of nursing professionals reported requesting at least one HIV-serology in the last 12 months (median: 15 and 2 HIV-serology request, respectively). The doctors associated the request with: being male (aOR: 2.95; 95% CI: 0.82-10.56), being trained in pre-post HIV test counselling (aOR: 2.42; 95% CI: 0.84-6.93) and the nurses with: age (<50 years; aOR: 2.75; 95% CI: 0.97-7.75), and number of years working in primary care (>13 years; aOR: 3.02; 95% CI: 1.07-8.52). It is necessary to promote HIV testing and training in pre-post HIV test counselling for medical and nursing professionals in primary care centres. Copyright © 2017 Elsevier España, S.L.U.

Epidermal growth factor receptor (egfr) tyrosine kinase inhibitors (tkis) are recommended as first-line systemic therapy for patients with non-small-cell lung cancer (nsclc) having mutations in the EGFR gene. Resistance to tkis eventually occurs in all nsclc patients treated with such drugs. In patients with resistance to tkis caused by the EGFR T790M mutation, the third-generation tki osimertinib is now the standard of care. For optimal patient management, accurate EGFR T790M testing is required. A multidisciplinary working group of pathologists, laboratory medicine specialists, medical oncologists, a respirologist, and a thoracic radiologist from across Canada was convened to discuss best practices for EGFR T790M mutation testing in Canada. The group made recommendations in the areas of the testing algorithm and the pre-analytic, analytic, and post-analytic aspects of clinical testing for both tissue testing and liquid biopsy circulating tumour dna testing. The recommendations aim to improve EGFR T790M testing in Canada and to thereby improve patient care.

Introduction  Toxoplasmosis a parasitic zoonosis of global distribution, responsible for disorders during gestation can cause fetal death or congenital anomalies. Objective  To evaluate the knowledge of toxoplasmosis among pregnant and postpartum women treated at the University Hospital of the city of Rio Grande, Rio Grande do Sul, Brazil. Methods  This was a cross-sectional study of 100 pregnant and postpartum women at the University Hospital. Participants answered a self-administered questionnaire and gave consent for data relating to serological examinations to be abstracted from their medical records. Results  The proportion of women who received information about toxoplasmosis was higher among those who received care in the private health care system (52.9%) than among those cared for in the public health care system (25.0%). Only 55.7% of women reported having some knowledge about toxoplasmosis. Of these, 53.7% received information during the prenatal period. However, most participants were unable to answer questions about preventive measures and modes of infection. Of the 100 patients in the study, only 46 underwent serologic testing for toxoplasmosis, 65.2% of whom tested negative (IgG). Conclusion  Findings from this study are relevant to the training of health professionals regarding toxoplasmosis education and prevention. Improved education for health care providers and patients can lead to earlier diagnoses and reductions in adverse outcomes. Thieme Publicações Ltda Rio de Janeiro, Brazil.

The failure of providers to communicate and follow up clinically significant test results (CSTR) is an important threat to patient safety. The Massachusetts Coalition for the Prevention of Medical Errors has endorsed the creation of systems to ensure that results can be received and acknowledged. In 2008 a task force was convened that represented clinicians, laboratories, radiology, patient safety, risk management, and information systems in a large health care network with the goals of providing recommendations and a road map for improvement in the management of CSTR and of implementing this improvement plan during the sub-force sequent five years. In drafting its charter, the task broadened the scope from "critical" results to "clinically significant" ones; clinically significant was defined as any result that requires further clinical action to avoid morbidity or mortality, regardless of the urgency of that action. The task force recommended four key areas for improvement--(1) standardization of policies and definitions, (2) robust identification of the patient's care team, (3) enhanced results management/tracking systems, and (4) centralized quality reporting and metrics. The task force faced many challenges in implementing these recommendations, including disagreements on definitions of CSTR and on who should have responsibility for CSTR, changes to established work flows, limitations of resources and of existing information systems, and definition of metrics. This large-scale effort to improve the communication and follow-up of CSTR in a health care network continues with ongoing work to address implementation challenges, refine policies, prepare for a new clinical information system platform, and identify new ways to measure the extent of this important safety problem.

Asthma is a common childhood chronic lung disease affecting greater than 10% of children in the United States. School nurses are in a unique position to close gaps in care. Indeed, effective asthma management is more likely to result when providers, family, and schools work together to optimize the patient's treatment plan. Currently, effective communication between schools and healthcare systems through electronic medical record (EMR) systems remains a challenge. The goal of this feasibility pilot was to link the school-based care team with primary care providers in the healthcare system network via electronic communication through the EMR, on behalf of pediatric asthma patients who had been hospitalized for an asthma exacerbation. The implementation process and the potential impact of the communication with providers on the reoccurrence of asthma exacerbations with the linked patients were evaluated. By engaging stakeholders from the school system and the healthcare system, we were able to collaboratively design a communication process and implement a pilot which demonstrated the feasibility of electronic communication between school nurses and primary care providers. Outcomes data was collected from the electronic medical record to examine the frequency of asthma exacerbations among patients with a message from their school nurse. The percent of exacerbations in the 12 months before and after electronic communication was compared using McNemar's test. The pilot system successfully established communication between the school nurse and primary care provider for 33 students who had been hospitalized for asthma and a decrease in hospital admissions was observed with students whose school nurse communicated through the EMR with the primary care provider. Findings suggest a collaborative model of care that is enhanced through electronic communication via the EMR could positively impact the health of children with asthma or other chronic illnesses.

To test a population health program which could, through the application of process redesign, implement multiple evidence-based practices across the continuum of care in a functionally integrated health delivery system and deliver highly reliable and consistent evidence-based surgical care for patients with fragility hip fractures in an acute tertiary general hospital. The ValuedCare (VC) program was developed in three distinct phases as an ongoing collaboration between the Geisinger Health System (GHS), USA, and Changi General Hospital (CGH), Singapore, modelled after the GHS ProvenCare® Fragile Hip Fracture Program. Clinical outcome data on consecutive hip fracture patients seen in 12 months pre-intervention were then compared with the post-intervention group. Both pre- and post-intervention groups were followed up across the continuum of care for a period of 12 months. VC patients showed significant improvement in median time to surgery (97 to 50.5 h), as well as proportion of patients operated within 48 h from hospital admission (48% from 18.8%) as compared to baseline pre-intervention data. These patients also had significant reduction (p value < 0.001) of acute inpatient complications such as delirium, pneumonia, urinary tract infections, and pressure sores. VC program has shown significant reduction in median length of stay for acute hospital (13 to 9 days) as well as median combined length of stay for acute and sub-acute rehabilitation hospital (46 to 39 days), thus reducing the total duration of hospitalization and saving total hospital bed days. Operative and inpatient mortality, together with readmission rates, remained low and comparable to international Geriatric Fracture Centers (GFCs). The implementation of VC methodology has enabled consistent delivery of high-quality, reliable and comprehensive evidence-based care for hip fracture patients at Changi General Hospital. This has also reflected successful change management and interdisciplinary collaboration within the organization through the program. There is potential for testing this methodology as a quality improvement framework replicable to other disease groups in a functionally integrated healthcare system.

Contrasting Medical and Legal Standards of Evidence: A Precision Medicine Case Study

Precis As the health care system transitions to a precision medicine approach that tailors clinical care to the genetic profile of the individual patient, there is a potential tension between the clinical uptake of new technologies by providers and the legal system’s expectation of the standard of care in applying such technologies. We examine this tension by comparing the type of evidence that physicians and courts are likely to rely on in determining a duty to recommend pharmacogenetic testing of patients prescribed the oral anti-coagulant drug warfarin. There is a large body of inconsistent evidence and factors for and against such testing, but physicians and courts are likely to weigh this evidence differently. The potential implications for medical malpractice risk are evaluated and discussed. PMID:27256135

For a technology to be implemented successfully, it must be thoroughly tested by the stakeholders who will use it in practice. This article reports on the user testing of the Nurse Computer Decision Support working prototype. Ten acute care nurses with varying levels of education and experience participated in the testing. The study's protocol consisted of a series of tasks requiring the participants to use the system while solving patient problems. Both quantitative and qualitative data on usability, ease of navigation, and nurse satisfaction were collected. The nurses ranked usability and ease of navigation highly. Nurses were excited about the system's clinical potential and felt that it would be useful to all practitioners regardless of experience. Testing the system in an actual clinical setting is the next step, but it is clear that the system has extraordinary potential to improve clinical decision making and patient outcomes.

Our research group advanced a health insurance theory to explain Canada's cancer care advantages over America. The late Barbara Starfield theorized that Canada's greater primary care-orientation also plays a critically protective role. We tested the resultant Starfield-Gorey theory by examining the effects of poverty, health insurance and physician supplies, primary care and specialists, on colon cancer care in Ontario and California. We analyzed registry data for people with non-metastasized colon cancer from Ontario (n = 2,060) and California (n = 4,574) diagnosed between 1996 and 2000 and followed to 2010. We obtained census tract-based socioeconomic data from population censuses and data on county-level physician supplies from national repositories: primary care physicians, gastroenterologists and other specialists. High poverty neighborhoods were oversampled and the criterion was 10 year survival. Hypotheses were explored with standardized rate ratios (RR) and tested with logistic regression models. Significant inverse associations of poverty (RR = 0.79) and inadequate health insurance (RR = 0.80) with survival were observed in the California, while they were non-significant or non-existent in Ontario. The direct associations of primary care physician (RRs of 1.32 versus 1.11) and gastroenterologist (RRs of 1.56 versus 1.15) supplies with survival were both stronger in Ontario than California. The supply of primary care physicians took precedence. Probably mediated through the initial course of treatment, it largely explained the Canadian advantage. Poverty and health insurance were more predictive in the USA, community physician supplies more so in Canada. Canada's primary care protections were greatest among the most socioeconomically vulnerable. The protective effects of Canadian health care prior to enactment of the Affordable Care Act (ACA) clearly suggested the following. Notwithstanding the importance of insuring all, strengthening America's system of primary care will probably be the best way to ensure that the ACA's full benefits are realized. Finally, Canada's strong primary care system ought to be maintained.

In the United States, Latino men who have sex with men (MSM) are disproportionately affected by HIV. Latino MSM are a diverse group who differ culturally based on their countries or regions of birth and their time in the United States. We assessed differences in HIV prevalence and testing among Latino MSM by location of birth, time since arrival, and other social determinants of health. For the 2008 National HIV Behavioral Surveillance System, a cross-sectional survey conducted in large US cities, MSM were interviewed and tested for HIV infection. We used generalized estimating equations to test associations between various factors and 1) prevalent HIV infection and 2) being tested for HIV infection in the past 12 months. Among 1734 Latino MSM, HIV prevalence was 19%. In multivariable analysis, increasing age, low income, and gay identity were associated with HIV infection. Moreover, men who were U.S.-born or who arrived ≥5 years ago had significantly higher HIV prevalence than recent immigrants. Among men not reporting a previous positive HIV test, 63% had been tested for HIV infection in the past 12 months; recent testing was most strongly associated with having seen a health care provider and disclosing male-male attraction/sexual behavior to a health care provider. We identified several social determinants of health associated with HIV infection and testing among Latino MSM. Lower HIV prevalence among recent immigrants contrasts with higher prevalence among established immigrants and suggests a critical window of opportunity for HIV prevention, which should prioritize those with low income, who are at particular risk for HIV infection. Expanding health care utilization and encouraging communication with health care providers about sexual orientation may increase testing.

Systems-based practice (SBP) is rarely taught or evaluated during medical school, yet is one of the required competencies once students enter residency. We believe Texas A&M College of Medicine students learn about systems issues informally, as they care for patients at a free clinic in Temple, TX. The mandatory free clinic rotation is part of the Internal Medicine clerkship and does not include formal instruction in SBP. During 2008-2009, a sample of students (n = 31) on the IMED clerkship's free clinic rotation participated in a program evaluation/study regarding their experiences. Focus groups (M = 5 students/group) were held at the end of each outpatient rotation. Students were asked: "Are you aware of any system issues which can affect either the delivery of or access to care at the free clinic?" Data saturation was reached after six focus groups, when investigators noted a repetition of responses. Based upon investigator consensus opinion, data collection was discontinued. Based upon a content analysis, six themes were identified: access to specialists, including OB-GYN, was limited; cost containment; lack of resources affects delivery of care; delays in care due to lack of insurance; understanding of larger healthcare system and free clinic role; and delays in tests due to language barriers. Medical students were able to learn about SBP issues during free clinic rotations. Students experienced how SBP issues affected the health care of uninsured individuals. We believe these findings may be transferable to medical schools with mandatory free clinic rotations.

Testing of a variable-stroke Stirling engine at NASA Lewis has been completed. In support of the DOE Stirling Engine Highway Vehicle Systems Program, the engine was tested for about 70 hours total with both He and H2 as working fluids over a range of pressures and strokes. A direct comparison was made of part-load efficiencies obtained with variable-stroke (VS) and variable-pressure operation. Two failures with the variable-angle swash-plate drive system limited testing to low power levels. These failures are not thought to be caused by problems inherent with the VS concept but do emphasize the need for careful design in the area of the crossheads.

Understanding the way health care reforms have succeeded or failed thus far would help policy makers cater continued reform efforts in the future and provides insight into possible levels of improvement in the health care system. This work aims to assess and describe the implications of health care reform on the performance of public hospitals in central Ethiopia. A facility-based, cross-sectional study was carried out in five public hospitals with different operational characteristics that have been implementing health care reform in central Ethiopia. The reform documents were reviewed to assess the nature and targets of the reform for interpretive analysis. Adopting dimensions of health system performance as the theoretical framework, a self-administered questionnaire was developed. Consenting health care professionals who have been involved in the reform from inception to implementation filled the questionnaire. Cronbach's alpha was measured to ensure internal consistency of the instrument. Descriptive statistics, weighted median score, χ 2 , and Mann-Whitney U and Kruskal-Wallis tests were used for data analysis. s Despite implementation of the reform, the health care system in public hospitals was still fragmented as confirmed by 50% of respondents. Limited effects were reported in favour of quality (48%), access (50%), efficiency (51%), sustainability (53%), and equity (61%) of care, while poor effects were reported in patient-provider (41%) and provider-management (32%) interactions. Though there was substantial gain in infrastructure and workspace, stewardship of health care resources was less benefited. The predominant hindrances of the reform were the working environment (adjusted Odds Ratio (aOR) = 2.27, 95% confidence interval (CI): 1.15-4.47), financial resources (aOR = 3.54, 95%CI = 1.97-6.33), management (aOR = 2.27, 95% CI = 1.15-4.47), and information technology system (aOR = 3.15, 95% CI = 1.57-6.32). s The Ethiopian health care reform has laid the groundwork for health system improvement, but progress was slow and the health care delivery system was still fragile. Healthcare reform efforts in such settings are feasible, but with regular mapping of programmatic outcomes and bringing a common understanding of the reform among stakeholders.

Understanding the medical and nonmedical value of diagnostic testing.

Lee, David W; Neumann, Peter J; Rizzo, John A

To develop a framework for defining the potential value of diagnostic testing, and discuss its implications for the health-care delivery system. We reviewed the conceptual and empirical literature related to the valuing of diagnostic tests, and used this information to create a framework for characterizing their value. We then made inferences about the impact of this framework on health insurance coverage, health technology assessment, physician-patient relationships, and public health policy. Three dimensions can effectively classify the potential value created by diagnostic tests: 1) medical value (impact on treatment decisions); 2) planning value (affect on patients' ability to make better life decisions); and 3) psychic value (how test information affects patients' sense of self). This comprehensive framework for valuing diagnostics suggests that existing health technology assessments may systematically under- or overvalue diagnostics, leading to potentially incorrect conclusions about cost-effectiveness. Further, failure to account for all value dimensions may lead to distorted payments under a value-based health-care system. The potential value created by medical diagnostics incorporates medical value as well as value associated with well-being and planning. Consideration of all three dimensions has important implications for technology assessment and value-based payment.

High performance work systems: the gap between policy and practice in health care reform.

Studies of high-performing organisations have consistently reported a positive relationship between high performance work systems (HPWS) and performance outcomes. Although many of these studies have been conducted in manufacturing, similar findings of a positive correlation between aspects of HPWS and improved care delivery and patient outcomes have been reported in international health care studies. The purpose of this paper is to bring together the results from a series of studies conducted within Australian health care organisations. First, the authors seek to demonstrate the link found between high performance work systems and organisational performance, including the perceived quality of patient care. Second, the paper aims to show that the hospitals studied do not have the necessary aspects of HPWS in place and that there has been little consideration of HPWS in health system reform. The paper draws on a series of correlation studies using survey data from hospitals in Australia, supplemented by qualitative data collection and analysis. To demonstrate the link between HPWS and perceived quality of care delivery the authors conducted regression analysis with tests of mediation and moderation to analyse survey responses of 201 nurses in a large regional Australian health service and explored HRM and HPWS in detail in three casestudy organisations. To achieve the second aim, the authors surveyed human resource and other senior managers in all Victorian health sector organisations and reviewed policy documents related to health system reform planned for Australia. The findings suggest that there is a relationship between HPWS and the perceived quality of care that is mediated by human resource management (HRM) outcomes, such as psychological empowerment. It is also found that health care organisations in Australia generally do not have the necessary aspects of HPWS in place, creating a policy and practice gap. Although the chief executive officers of health service organisations reported high levels of strategic HRM, the human resource and other managers reported a distinct lack of HPWS from their perspectives. The authors discuss why health care organisations may have difficulty in achieving HPWS. Leaders in health care organisations should focus on ensuring human resource management systems, structures and processes that support HPWS. Policy makers need to consider HPWS as a necessary component of health system reform. There is a strong need to reorient organisational human resource management policies and procedures in public health care organisations towards high performing work systems.

To present results, 1 year postimplementation at primary care level, of an integrated diabetes care programme including systemic changes, education, registry (clinical, metabolic, and therapeutic indicators), and disease management (DIAPREM). We randomly selected and trained 15 physicians and 15 nurses from primary care units of La Matanza County (intervention-IG) and another 15 physicians/nurses to participate as controls (control-CG). Each physician-nurse team controlled and followed up 10 patients with type 2 diabetes for 1 year; both groups used structured medical records. Patients in IG had quarterly clinical appointments, whereas those in CG received traditional care. Statistical data analysis included parametric/nonparametric tests according to data distribution profile and Chi-squared test for proportions. After 12 months, the dropout rate was significantly lower in IG than in CG. Whereas in IG HbA1c, blood pressure and lipid profile levels significantly decreased, no changes were recorded in CG. Drug prescriptions showed no significant changes in IG except a decrease in oral monotherapy. DIAPREM is an expedient and simple multistrategic model to implement at the primary care level in order to decrease patient dropout and improve control and treatment adherence, and quality of care of people with diabetes.

Supervised Patient Self-Testing of Warfarin Therapy Using an Online System

PubMed Central

2013-01-01

Background Point-of-care international normalized ratio (INR) monitoring devices simplify warfarin management by allowing selected patients to monitor their own therapy in their homes. Patient self-testing (PST) has been shown to improve the clinical outcomes of warfarin therapy compared to usual care. Objective To compare management of warfarin therapy using PST combined with online supervision by physicians via a custom system with usual warfarin management, which involved laboratory testing and physician dosing. Methods Interested patients were recruited via community pharmacies to participate in a warfarin PST training program. Participants were required to have a long-term indication for warfarin, have been taking warfarin for at least 6 months, and have Internet access in their home. The training involved two sessions covering theoretical aspects of warfarin therapy, use of the CoaguChek XS, and the study website. Following training, patients monitored their INR once weekly for up to 3 months. Patients and physicians utilized a secure website to communicate INR values, dosage recommendations, and clinical incidents. Physicians provided a 6-12 month history of INR results for comparison with study results. The percentage of time spent within the therapeutic INR range (TTR) was the primary outcome, with participants acting as their own historical controls. The percentage of INR tests in range and participant satisfaction were secondary outcomes. Results Sixteen patients completed training requirements. The mean age of participants was 69.8 (SD 10.1) years. TTR improved significantly from 66.4% to 78.4% during PST (P=.01), and the number of tests within the target range also improved significantly (from 66.0% at prior to the study to 75.9% during PST; P=.04). Patients and physicians expressed a high degree of satisfaction with the monitoring strategy and online system. Conclusions PST supported by an online system for supervision was associated with improved INR control compared to usual care in a small group of elderly patients. Further research is warranted to investigate the clinical outcomes and cost-effectiveness of online systems to support patients monitoring medications and chronic conditions in the home.

Online evidence retrieval systems are one potential tool in supporting evidence-based practice. We have undertaken a program of research to investigate how hospital-based clinicians (doctors, nurses and allied health professionals) use these systems, factors influencing use and their impact on decision-making and health care delivery. A central component of this work has been the development and testing of a broad range of evaluation techniques. This paper provides an overview of the results obtained from three stages of this evaluation and details the results derived from the final stage which sought to test two methods for assessing the integration of an online evidence system and its impact on decision making and patient care. The critical incident and journey mapping techniques were applied. Semi-structured interviews were conducted with 29 clinicians who were experienced users of the online evidence system. Clinicians were asked to described recent instances in which the information obtained using the online evidence system was especially helpful with their work. A grounded approach to data analysis was taken producing three categories of impact. The journey mapping technique was adapted as a method to describe and quantify clinicians' integration of CIAP into their practice and the impact of this on patient care. The analogy of a journey is used to capture the many stages in this integration process, from introduction to the system to full integration into everyday clinical practice with measurable outcomes. Transcribed interview accounts of system use were mapped against the journey stages and scored. Clinicians generated 85 critical incidents and one quarter of these provided specific examples of system use leading to improvements in patient care. The journey mapping technique proved to be a useful method for providing a quantification of the ways and extent to which clincians had integrated system use into practice, and insights into how information systems can influence organisational culture. Further work is required on this technique to assess its value as an evaluation method. The study demonstrates the strength of a triangulated evidence approach to assessing the use and impact of online clinical evidence systems.

A nursing record system is the record of care that was planned or given to individual patients and clients by qualified nurses or other caregivers under the direction of a qualified nurse. Nursing record systems may be an effective way of influencing nurse practice. To assess the effects of nursing record systems on nursing practice and patient outcomes. For the original version of this review in 2000, and updates in 2003 and 2008, we searched: the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register; MEDLINE, EMBASE, CINAHL, BNI, ISI Web of Knowledge, and ASLIB Index of Theses. We also handsearched: Computers, Informatics, Nursing (Computers in Nursing); Information Technology in Nursing; and the Journal of Nursing Administration. For this update, searches can be considered complete until the end of 2007. We checked reference lists of retrieved articles and other related reviews. Randomised controlled trials (RCTs), controlled before and after studies, and interrupted time series comparing one kind of nursing record system with another in hospital, community or primary care settings. The participants were qualified nurses, students or healthcare assistants working under the direction of a qualified nurse, and patients receiving care recorded or planned using nursing record systems. Two review authors (in two pairs) independently assessed trial quality and extracted data. We included nine trials (eight RCTs, one controlled before and after study) involving 1846 people. The studies that evaluated nursing record systems focusing on relatively discrete and focused problems, for example effective pain management in children, empowering pregnant women and parents, reducing loss of notes, reducing time spent on data entry of test results, reducing transcription errors, and reducing the number of pieces of paper in a record, all demonstrated some degree of success in achieving the desired results. Studies of nursing care planning systems and total nurse records demonstrated uncertain or equivocal results. We found some limited evidence of effects on practice attributable to changes in record systems. It is clear from the literature that it is possible to set up the randomised trials or other quasi-experimental designs needed to produce evidence for practice. Qualitative nursing research to explore the relationship between practice and information use could be used as a precursor to the design and testing of nursing information systems.

The critical care air transport team program is a component of the U.S. Air Force Aeromedical Evacuation system. A critical care air transport team consists of a critical care physician, critical care nurse, and respiratory therapist along with the supplies and equipment to operate a portable intensive care unit within a cargo aircraft. This capability was developed to support rapidly mobile surgical teams with high capability for damage control resuscitation and limited capacity for postresuscitation care. The critical care air transport team permits rapid evacuation of stabilizing casualties to a higher level of care. The aeromedical environment presents important challenges for the delivery of critical care. All equipment must be tested for safety and effectiveness in this environment before use in flight. The team members must integrate the current standards of care with the limitation imposed by stresses of flight on their patient. The critical care air transport team capability has been used successfully in a range of settings from transport within the United States, to disaster response, to support of casualties in combat.

Access to health care in the Scandinavian countries: ethical aspects.

Holm, S; Liss, P E; Norheim, O F

1999-01-01

The health care systems are fairly similar in the Scandinavian countries. The exact details vary, but in all three countries the system is almost exclusively publicly funded through taxation, and most (or all) hospitals are also publicly owned and managed. The countries also have a fairly strong primary care sector (even though it varies between the countries), with family physicians to various degrees acting as gatekeepers to specialist services. In Denmark most of the GP services are free. For the patient in Norway and Sweden there are out-of-pocket co-payments for GP consultations, with upper limits, but consultations for children are free. Hospital treatment is free in Denmark while the other countries use a system with out-of-pocket co-payment. There is a very strong public commitment to access to high quality health care for all. Solidarity and equality form the ideological basis for the Scandinavian welfare state. Means testing, for instance, has been widely rejected in the Scandinavian countries on the grounds that public services should not stigmatise any particular group. Solidarity also means devoting special consideration to the needs of those who have less chance than others of making their voices heard or exercising their rights. Issues of limited access are now, however, challenging the thinking about a health care system based on solidarity.

Electronic information technology standards facilitate high-quality, uniform collection of data for improved delivery and measurement of health care services. Electronic information standards also aid information exchange between secure systems that link health care and public health for better coordination of patient care and better-informed population health improvement activities. We developed international data standards for healthy weight that provide common definitions for electronic information technology. The standards capture healthy weight data on the "ABCDs" of a visit to a health care provider that addresses initial obesity prevention and care: assessment, behaviors, continuity, identify resources, and set goals. The process of creating healthy weight standards consisted of identifying needs and priorities, developing and harmonizing standards, testing the exchange of data messages, and demonstrating use-cases. Healthy weight products include 2 message standards, 5 use-cases, 31 LOINC (Logical Observation Identifiers Names and Codes) question codes, 7 healthy weight value sets, 15 public-private engagements with health information technology implementers, and 2 technical guides. A logic model and action steps outline activities toward better data capture, interoperable systems, and information use. Sharing experiences and leveraging this work in the context of broader priorities can inform the development of electronic information standards for similar core conditions and guide strategic activities in electronic systems.

Electronic information technology standards facilitate high-quality, uniform collection of data for improved delivery and measurement of health care services. Electronic information standards also aid information exchange between secure systems that link health care and public health for better coordination of patient care and better-informed population health improvement activities. We developed international data standards for healthy weight that provide common definitions for electronic information technology. The standards capture healthy weight data on the “ABCDs” of a visit to a health care provider that addresses initial obesity prevention and care: assessment, behaviors, continuity, identify resources, and set goals. The process of creating healthy weight standards consisted of identifying needs and priorities, developing and harmonizing standards, testing the exchange of data messages, and demonstrating use-cases. Healthy weight products include 2 message standards, 5 use-cases, 31 LOINC (Logical Observation Identifiers Names and Codes) question codes, 7 healthy weight value sets, 15 public–private engagements with health information technology implementers, and 2 technical guides. A logic model and action steps outline activities toward better data capture, interoperable systems, and information use. Sharing experiences and leveraging this work in the context of broader priorities can inform the development of electronic information standards for similar core conditions and guide strategic activities in electronic systems.

As reimbursement transitions from a volume-based to a value-based system, innovation in health care delivery will be needed. The process of innovation begins with framing the problem that needs to be solved along with the strategic vision that has to be achieved. Similar to scientific testing, a hypothesis is generated for a new solution to a problem. Innovation requires conducting a disciplined form of experimentation and then learning from the process. This manuscript will discuss the different types of innovation, and the key steps necessary for successful innovation in the health care field.

Migrant Chinese populations in Western countries have a high prevalence of chronic hepatitis B but often experience poor access to health care and late diagnosis. This systematic review aimed to identify obstacles and supports to timely and appropriate health service use among these populations. Systematic searches resulted in 48 relevant studies published between 1996 and 2015. Data extraction and synthesis were informed by models of healthcare access that highlight the interplay of patient, provider and health system factors. There was strong consistent evidence of low levels of knowledge among patients and community members; but interventions that were primarily focused on increasing knowledge had only modest positive effects on testing and/or vaccination. There was strong consistent evidence that Chinese migrants tend to misunderstand the need for health care for hepatitis B and have low satisfaction with services. Stigma was consistently associated with hepatitis B, and there was weak but consistent evidence of stigma acting as a barrier to care. However, available evidence on the effects of providing culturally appropriate services for hepatitis B on increasing uptake is limited. There was strong consistent evidence that health professionals miss opportunities for testing and vaccination. Practitioner education interventions may be important, but evidence of effectiveness is limited. A simple prompt in patient records for primary care physicians improved the uptake of testing, and a dedicated service increased targeted vaccination coverage for newborns. Further development and more rigorous evaluation of more holistic approaches that address patient, provider and system obstacles are needed. © 2017 The Authors.

This study presents an optical inspection system for detecting a commercial point-of-care testing product and a new detection model covering from qualitative to quantitative analysis. Human chorionic gonadotropin (hCG) strips (cut-off value of the hCG commercial product is 25 mIU/mL) were the detection target in our study. We used a complementary metal-oxide semiconductor (CMOS) sensor to detect the colors of the test line and control line in the specific strips and to reduce the observation errors by the naked eye. To achieve better linearity between the grayscale and the concentration, and to decrease the standard deviation (increase the signal to noise ratio, S/N), the Taguchi method was used to find the optimal parameters for the optical inspection system. The pregnancy test used the principles of the lateral flow immunoassay, and the colors of the test and control line were caused by the gold nanoparticles. Because of the sandwich immunoassay model, the color of the gold nanoparticles in the test line was darkened by increasing the hCG concentration. As the results reveal, the S/N increased from 43.48 dB to 53.38 dB, and the hCG concentration detection increased from 6.25 to 50 mIU/mL with a standard deviation of less than 10%. With the optimal parameters to decrease the detection limit and to increase the linearity determined by the Taguchi method, the optical inspection system can be applied to various commercial rapid tests for the detection of ketamine, troponin I, and fatty acid binding protein (FABP).

Although various guidelines and position papers have discussed, in the past, the ethical aspects of genetic testing in asymptomatic minors, the European Society of Human Genetics had not earlier endorsed any set of guidelines exclusively focused on this issue. This paper has served as a background document in preparation of the development of the policy recommendations of the Public and Professional Committee of the European Society of Human Genetics. This background paper first discusses some general considerations with regard to the provision of genetic tests to minors. It discusses the concept of best interests, participation of minors in health-care decisions, parents' responsibilities to share genetic information, the role of clinical genetics and the health-care system in communication within the family. Second, it discusses, respectively, the presymptomatic and predictive genetic testing for adult-onset disorders, childhood-onset disorders and carrier testing. PMID:19277061

Prompt and accurate diagnosis is needed to prevent the untoward effects of anaemia on children. Although haematology analyzers are the gold standard for accurate measurement of haemoglobin or haematocrit for anaemia diagnosis, they are often out of the reach of most health facilities in resource-poor settings thus creating a care gap. We conducted this study to examine the agreement between a point-of-care device and haematology analyzer in determining the haematocrit levels in children and to determine its usefulness in diagnosing anaemia in resource-poor settings. EDTA blood samples collected from participants were processed to estimate their haematocrits using the two devices (Mindray BC-3600 haematology analyzer and Portable Mission Hb/Haemotocrit testing system). A pairwise t-test was used to compare the haematocrit (PCV) results from the automated haematology analyzer and the portable haematocrit meter. The agreement between the two sets of measurements was assessed using the Bland and Altman method where the mean, standard deviation and limit of agreement of paired results were calculated. The intraclass and concordance correlation coefficients were 0.966 and 0.936. Sensitivity and specificity were 97.85% and 94.51% respectively while the positive predictive and negative predictive values were 94.79% and 97.73%. The Bland and Altman`s limit of agreement was -5.5-5.1 with the mean difference being -0.20 and a non-ignificant variability between the two measurements (p = 0.506). Haematocrit determined by the portable testing system is comparable to that determined by the haematology analyzer. We therefore recommend its use as a point-of-care device for determining haematocrit in resource-poor settings where haematology analyzers are not available.

The increase in numbers of patients requiring oral anti-coagulation testing in outpatient clinics has focused attention on alternative flexible systems of anti-coagulation management. One option is pharmacist led patient self-testing (PST) of international normalised ratio (INR) levels. PST has demonstrated improvements in anti-coagulation control, but its cost-effectiveness is inconclusive. This study reports the first cost-effectiveness evaluation of a randomized controlled trial of an automated direct-to-patient expert system, enabling remote and effective management of patients on oral anti-coagulation therapy. We conducted an economic evaluation alongside a randomised controlled trial investigating a pharmacist led PST method. The primary outcome was to determine the cost effectiveness of PST in comparison with usual care (management in a hospital based anti-coagulation clinic). Long term anti-coagulation patients were recruited to a 6 month cross over study between PST and routine care in an anti-coagulation clinic. Economic evaluation was from the healthcare payer perspective. On a per patient basis over a 6 month period, PST resulted in an incremental cost of €59.08 in comparison with routine care. Patients achieved a significantly higher time in therapeutic range (TTR) during the PST arm in comparison with routine care, (72 ± 19.7% vs. 59 ± 13.5%). Overall cost of managing a patient through pharmacist supervised PST for a 6 month period is €226.45. Additional analysis of strategies from a societal perspective indicated that PST was the dominant strategy. Pharmacist led patient self-testing is a viable method of management. It provides significant increases in anti-coagulation control for a minimal increase in cost. © 2014 John Wiley & Sons Ltd.

There exists a broad range of techniques that can be used to classify and count white blood cells in a point-of-care (POC) three-part leukocyte differential test. Improvements in lenses, light sources, and cameras for image-based POC systems have renewed interest in acridine orange (AO) as a contrast agent, whereby subpopulations of leukocytes can be differentiated by colorimetric analysis of AO fluorescence emission. We evaluated the effect on test accuracy using different AO staining and postprocessing methods in the context of an image-based POC colorimetric cell classification scheme. Thirty blood specimens were measured for percent cell counts using our POC system and a conventional hematology analyzer for comparison. Controlling the AO concentration used during whole-blood staining, the incubation time with AO, and the colorimetric ratios among the three population of leukocytes yielded a percent deviation of 0.706%, -1.534%, and -0.645% for the lymphocytes, monocytes, and granulocytes, respectively. Overall, we demonstrated that a redshift in AO fluorescence was observed at elevated AO concentrations, which lead to reproducible inaccuracy of cell counts. This study demonstrates there is a need for a strict control of the AO staining and postprocessing methods to improve test accuracy in these POC systems.

Clinical pathology (CP) laboratories are used for millions of tests each year. These lead to thousands of calls to CP residents. However, although laboratory utilization is a frequent topic of study, clinical utilization--the content of the interactions between clinicians and CP residents--is not. Because it reflects questions about laboratory utilization, clinical utilization could suggest ways to improve both training and care by reducing diagnostic error. To build and implement a secure, scalable Web-based system to allow CP residents at any hospital to track the calls they receive, the interaction's context, and the action taken as a result, with evidence where applicable, and to use this system to report on clinical utilization at a major academic hospital. Entries were analyzed from a nearly year-long period to describe the clinical utilization of CP at a large academic teaching hospital. Sixteen residents logged 847 calls during 10 months, roughly evenly distributed among transfusion medicine, chemistry, microbiology, and hematopathology. Calls covered 94 different analytes in chemistry and 71 different organisms or tests in microbiology. Analysis revealed areas where CP can improve clinical care through educating the clinical services, for example, about ordering Rh immune globulin, testosterone testing, and diagnosis of tick-borne diseases. Documenting calls also highlighted patterns among residents. Clinical utilization is a potentially rich knowledge base for improving patient care and resident training. Our resident call-tracking system is a useful way for measuring clinical utilization and mining it for actionable information.

The objective of this study was to determine the concordance between data extracted from two Clinical Decision Support Systems regarding diabetes testing and monitoring at Aboriginal Community Controlled Health Services in Australia. De-identified PenCAT and Communicare Systems data were extracted from the services allocated to the intervention arm of a diabetes care trial, and intra-class correlations for each extracted item were derived at a service level. Strong to very strong correlations between the two data sources were found regarding the total number of patients with diabetes per service (Intra-class correlation [ICC] = 0.99), as well as the number (ICC = 0.98-0.99) and proportion (ICC = 0.96) of patients with diabetes by gender. The correlation was moderate for the number and proportion of Type 2 diabetes patients per service in the group aged 18-34 years (ICC = 0.65 and 0.8-0.82 respectively). Strong to very strong correlations were found for numbers and proportions of patients being tested for diabetes, and for appropriate monitoring of patients known to have diabetes (ICC = 0.998-1.00). This indicated a generally high degree of concordance between whole-service data extracted by the two Clinical Decision Support Systems. Therefore, the less expensive or less complex option (depending on the individual circumstances of the service) may be appropriate for monitoring diabetes testing and care. However, the extraction of data about subgroups of patients may not be interchangeable.

The ubiquitous computing, or ubicomp, is a promising technology to help chronic diseases patients managing activities, offering support to them anytime, anywhere. Hence, ubicomp can aid community and health organizations to continuously communicate with patients and to offer useful resources for their self-management activities. Communication is prioritized in works of ubiquitous health for noncommunicable diseases care, but the management of resources is not commonly employed. We propose the UDuctor, a model for ubiquitous care of noncommunicable diseases. UDuctor focuses the resources offering, without losing self-management and communication supports. We implemented a system and applied it in two practical experiments. First, ten chronic patients tried the system and filled out a questionnaire based on the technology acceptance model. After this initial evaluation, an alpha test was done. The system was used daily for one month and a half by a chronic patient. The results were encouraging and show potential for implementing UDuctor in real-life situations.

Context: Primary care practice. Objective: To test whether the principles of complex adaptive systems are applicable to implementation of team-based primary care. Design: We used complex adaptive system principles to implement team-based care in a private, five-clinic primary care practice. We compared randomly selected samples of patients with coronary heart disease (CHD) and diabetes before system implementation (March 1, 2009, to February 28, 2010) and after system implementation (December 1, 2011, to March 31, 2013). Main Outcome Measures: Rates of patients meeting the composite goals for CHD (blood pressure < 140/90 mmHg, low-density lipoprotein cholesterol level < 100 mg/dL, tobacco-free, and using aspirin unless contraindicated) and diabetes (CHD goal plus hemoglobin A1c concentration < 8%) before and after the intervention. We also measured provider and patient satisfaction with preventive services. Results: The proportion of patients with CHD who met the composite goal increased from 40.3% to 59.9% (p < 0.0001) because documented aspirin use increased (65.2%–97.5%, p < 0.0001) and attainment of the cholesterol goal increased (77.0%–83.9%, p = 0.0041). The proportion of diabetic patients meeting the composite goal rose from 24.5% to 45.4% (p < 0.0001) because aspirin use increased (58.6%–97.6%, p < 0.0001). Increased percentages of patients meeting the CHD and diabetes composite goals were not significantly different (p = 0.2319). Provider satisfaction with preventive services delivery increased significantly (p = 0.0017). Patient satisfaction improved but not significantly. Conclusion: Principles of complex adaptive systems can be used to implement team-based care systems for patients with CHD and possibly diabetic patients. PMID:26784851
