    2014-12-01

    Condition-monitoring plays an increasingly important role for technical processes in order to improve reliability, availability, maintenance and lifetime of equipment. With increasing demands for efficiency and product quality, plus progress in the integration of automatic control systems in high-cost mechatronic and critical safety processes, the field of health monitoring is gaining interest. A similar research field is concerned with an estimation of the remaining useful life. A central question in these fields is the modelling of degradation; degradation is a process of a gradual and irreversible accumulation of damage which will finally result in a failure of the system. This paper is based on a current research project and explores various degradation modelling techniques. These results are explained on the basis of an industrial product - a system for the generation of health status information for pump systems. The result of this fuzzy-logic based system is a single number indicating the current health of a pump system.

    Today's public health programs are complex business systems with multiple levels of collaborating federal, state, and local entities. The use of proven systems engineering modeling techniques to analyze, align, and streamline public health operations is in the beginning stages. The authors review the initial business modeling efforts in immunization and cancer registries and present a case to broadly apply business modeling approaches to analyze and improve public health processes.

    Objectives. Awareness of and support for systems thinking and modeling in the public health field are growing, yet there are many practical challenges to implementation. We sought to identify and describe these challenges from the perspectives of practicing public health professionals. Methods. A systems-based methodology, concept mapping, was used in a study of 133 participants from 2 systems-based public health initiatives (the Initiative for the Study and Implementation of Systems and the Syndemics Prevention Network). This method identified 100 key challenges to implementation of systems thinking and modeling in public health work. Results. The project resulted in a map identifying 8 categories of challenges and the dynamic interactions among them. Conclusions. Implementation by public health professionals of the 8 simple rules we derived from the clusters in the map identified here will help to address challenges and improve the organization of systems that protect the public’s health.

    Rigorous methods for design and verification of health IT systems have lagged far behind their proliferation. The inherent technical complexity of healthcare, combined with the added complexity of health information technology makes their resulting behavior unpredictable and introduces serious risk. We propose to mitigate this risk by formalizing the relationship between HIT and the conceptual work that increasingly typifies modern care. We introduce new techniques for modeling clinical workflows and the conceptual products within them that allow established, powerful modeling checking technology to be applied to interactive health IT systems. The new capability can evaluate the workflows of a new HIT system performed by clinicians and computers to improve safety and reliability. We demonstrate the method on a patient contact system to demonstrate model checking is effective for interactive systems and that much of it can be automated. PMID:26958166

  5. Systems Modeling to Implement Integrated System Health Management Capability

    ISHM capability includes: detection of anomalies, diagnosis of causes of anomalies, prediction of future anomalies, and user interfaces that enable integrated awareness (past, present, and future) by users. This is achieved by focused management of data, information and knowledge (DIaK) that will likely be distributed across networks. Management of DIaK implies storage, sharing (timely availability), maintaining, evolving, and processing. Processing of DIaK encapsulates strategies, methodologies, algorithms, etc. focused on achieving high ISHM Functional Capability Level (FCL). High FCL means a high degree of success in detecting anomalies, diagnosing causes, predicting future anomalies, and enabling health integrated awareness by the user. A model that enables ISHM capability, and hence, DIaK management, is denominated the ISHM Model of the System (IMS). We describe aspects of the IMS that focus on processing of DIaK. Strategies, methodologies, and algorithms require proper context. We describe an approach to define and use contexts, implementation in an object-oriented software environment (G2), and validation using actual test data from a methane thruster test program at NASA SSC. Context is linked to existence of relationships among elements of a system. For example, the context to use a strategy to detect leak is to identify closed subsystems (e.g. bounded by closed valves and by tanks) that include pressure sensors, and check if the pressure is changing. We call these subsystems Pressurizable Subsystems. If pressure changes are detected, then all members of the closed subsystem become suspect of leakage. In this case, the context is defined by identifying a subsystem that is suitable for applying a strategy. Contexts are defined in many ways. Often, a context is defined by relationships of function (e.g. liquid flow, maintaining pressure, etc.), form (e.g. part of the same component, connected to other components, etc.), or space (e.g. physically close

    Systems health management (SHM) is an important set of technologies aimed at increasing system safety and reliability by detecting, isolating, and identifying faults; and predicting when the system reaches end of life (EOL), so that appropriate fault mitigation and recovery actions can be taken. Model-based SHM approaches typically make use of global, monolithic system models for online analysis, which results in a loss of scalability and efficiency for large-scale systems. Improvement in scalability and efficiency can be achieved by decomposing the system model into smaller local submodels and operating on these submodels instead. In this paper, the global system model is analyzed offline and structurally decomposed into local submodels. We define a common model decomposition framework for extracting submodels from the global model. This framework is then used to develop algorithms for solving model decomposition problems for the design of three separate SHM technologies, namely, estimation (which is useful for fault detection and identification), fault isolation, and EOL prediction. We solve these model decomposition problems using a three-tank system as a case study.

    There is a widespread need for the use of quantitative microbial risk assessment (QMRA) to determine reclaimed water quality for specific uses, however neither faecal indicator levels nor pathogen concentrations alone are adequate for assessing exposure health risk. The aim of this study was to build a conceptual model representing factors contributing to the microbiological health risks of reusing water treated in maturation ponds. This paper describes the development of an unparameterised model that provides a visual representation of theoretical constructs and variables of interest. Information was collected from the peer-reviewed literature and through consultation with experts from regulatory authorities and academic disciplines. In this paper we explore how, considering microbial risk as a modular system, following the QMRA framework enables incorporation of the many factors influencing human exposure and dose response, to better characterise likely human health impacts. By using and expanding upon the QMRA framework we deliver new insights into this important field of environmental exposures. We present a conceptual model of health risk of microbial exposure which can be used for maturation ponds and, more importantly, as a generic tool to assess health risk in diverse wastewater reuse scenarios.

    Objective To evaluate the complex dynamics involved in implementing electronic health information exchange (HIE) for public health reporting at a state health department, and to identify policy implications to inform similar implementations. Materials and methods Qualitative data were collected over 8 months from seven experts at New York State Department of Health who implemented web services and protocols for querying, receipt, and validation of electronic data supplied by regional health information organizations. Extensive project documentation was also collected. During group meetings experts described the implementation process and created reference modes and causal diagrams that the evaluation team used to build a preliminary model. System dynamics modeling techniques were applied iteratively to build causal loop diagrams representing the implementation. The diagrams were validated iteratively by individual experts followed by group review online, and through confirmatory review of documents and artifacts. Results Three casual loop diagrams captured well-recognized system dynamics: Sliding Goals, Project Rework, and Maturity of Resources. The findings were associated with specific policies that address funding, leadership, ensuring expertise, planning for rework, communication, and timeline management. Discussion This evaluation illustrates the value of a qualitative approach to system dynamics modeling. As a tool for strategic thinking on complicated and intense processes, qualitative models can be produced with fewer resources than a full simulation, yet still provide insights that are timely and relevant. Conclusions System dynamics techniques clarified endogenous and exogenous factors at play in a highly complex technology implementation, which may inform other states engaged in implementing HIE supported by federal Health Information Technology for Economic and Clinical Health (HITECH) legislation.

    PubMed Central

    2013-01-01

    Human lifespan is positively correlated with childhood intelligence, as measured by psychometric (IQ) tests. The strength of this correlation is similar to the negative effect that smoking has on the life course. This result suggests that people who perform well on psychometric tests in childhood may remain healthier and live longer. The correlation, however, is debated: is it caused exclusively by social-environmental factors or could it also have a biological component? Biological traits of systems integrity that might result in correlations between brain function and lifespan have been suggested but are not well-established, and it is questioned what useful knowledge can come from understanding such mechanisms. In a recent study, we found a positive correlation between brain function and longevity in honey bees. Honey bees are highly social, but relevant social-environmental factors that contribute to cognition-survival correlations in humans are largely absent from insect colonies. Our results, therefore, suggest a biological explanation for the correlation in the bee. Here, we argue that individual differences in stress handling (coping) mechanisms, which both affect the bees’ performance in tests of brain function and their survival could be a trait of systems integrity. Individual differences in coping are much studied in vertebrates, and several species provide attractive models. Here, we discuss how pigs are an interesting model for studying behavioural, physiological and molecular mechanisms that are recruited during stress and that can drive correlations between health, cognition and longevity traits. By revealing biological factors that make individuals susceptible to stress, it might be possible to alleviate health and longevity disparities in people. PMID:24472488

    Objectives Intensified competitiveness in the healthcare industry has increased the number of healthcare centers and propelled the introduction of customer relationship management (CRM) systems to meet diverse customer demands. This study aimed to develop the information system success model of the CRM system by investigating previously proposed indicators within the model. Methods The evaluation areas of the CRM system includes three areas: the system characteristics area (system quality, information quality, and service quality), the user area (perceived usefulness and user satisfaction), and the performance area (personal performance and organizational performance). Detailed evaluation criteria of the three areas were developed, and its validity was verified by a survey administered to CRM system users in 13 nationwide health promotion centers. The survey data were analyzed by the structural equation modeling method, and the results confirmed that the model is feasible. Results Information quality and service quality showed a statistically significant relationship with perceived usefulness and user satisfaction. Consequently, the perceived usefulness and user satisfaction had significant influence on individual performance as well as an indirect influence on organizational performance. Conclusions This study extends the research area on information success from general information systems to CRM systems in health promotion centers applying a previous information success model. This lays a foundation for evaluating health promotion center systems and provides a useful guide for successful implementation of hospital CRM systems. PMID:23882416

    Objective To model the impacts of the bicycle sharing system in London on the health of its users. Design Health impact modelling and evaluation, using a stochastic simulation model. Setting Central and inner London, England. Data sources Total population operational registration and usage data for the London cycle hire scheme (collected April 2011-March 2012), surveys of cycle hire users (collected 2011), and London data on travel, physical activity, road traffic collisions, and particulate air pollution (PM2.5, (collected 2005-12). Participants 578 607 users of the London cycle hire scheme, aged 14 years and over, with an estimated 78% of travel time accounted for by users younger than 45 years. Main outcome measures Change in lifelong disability adjusted life years (DALYs) based on one year impacts on incidence of disease and injury, modelled through medium term changes in physical activity, road traffic injuries, and exposure to air pollution. Results Over the year examined the users made 7.4 million cycle hire trips (estimated 71% of cycling time by men). These trips would mostly otherwise have been made on foot (31%) or by public transport (47%). To date there has been a trend towards fewer fatalities and injuries than expected on cycle hire bicycles. Using these observed injury rates, the population benefits from the cycle hire scheme substantially outweighed harms (net change −72 DALYs (95% credible interval −110 to −43) among men using cycle hire per accounting year; −15 (−42 to −6) among women; note that negative DALYs represent a health benefit). When we modelled cycle hire injury rates as being equal to background rates for all cycling in central London, these benefits were smaller and there was no evidence of a benefit among women (change −49 DALYs (−88 to −17) among men; −1 DALY (−27 to 12) among women). This sex difference largely reflected higher road collision fatality rates for female cyclists. At older ages the modelled

    This paper describes Cuba's experience with the Virtual Health University (VHU) as a strategic project of INFOMED, promoting creation of an open teaching-learning environment for health sciences education, through intensive and creative use of Information and Communication Technologies (ICTs) and a network approach to learning. An analysis of the VHU's main antecedents in its different stages of development provides insight into the strategic reasons that led to the establishment of a virtual university in the national health system during Cuba's so-called Special Period of economic crisis. Using the general objectives of creating, sharing, and collaborating which define the VHU's conceptual-operative framework, the three essential components (subsystems) are described: pedagogical, technological, and managerial, as well as the operative stages of educational design, technological implementation, and teaching-administrative management system. Each component of the model is analyzed in the context of global, modern university trends, towards integration of the face-to-face and distance education approaches and the creation of virtual institutions that assume the technological and pedagogical changes demanded by eLearning.

    Maglio, Paul P.; Cefkin, Melissa; Haas, Peter J.; Selinger, Pat

    The health system is a complex system of systems - changes in agriculture, transportation, economics, family life, medical practices, and many other things can have a profound influence on health and health costs. Yet today, policy-level investment decisions are frequently made by modeling individual systems in isolation. We describe two sets of issues that we face in trying to develop a platform, method, and service for integrating expert models from different domains to support health policy and investment decisions. The first set of questions concerns how to develop accurate social and behavioral health models and integrate them with engineering models of transportation, clinic operations, and so forth. The second set of questions concerns the design of an environment that will encourage and facilitate collaboration between the health modelers themselves, who come from a wide variety of disciplines.

    A high-resolution assessment of health impacts from air pollution and related external cost has been conducted for Denmark using the integrated EVA model system. The EVA system has been further developed by implementing an air quality model with a 1 km x 1 km resolution covering the whole of Denmark. New developments of the integrated model system will be presented as well as results for health impacts and related external costs over several decades. Furthermore, the sensitivity of health impacts to model resolution will be studied. We have developed an integrated model system EVA (Economic Valuation of Air pollution), based on the impact-pathway chain, to assess the health impacts and health-related economic externalities of air pollution resulting from specific emission sources or sectors. The system is used to support policymaking with respect to emission control. In Brandt et al. (2013a; 2013b), the EVA system was used to assess the impacts in Europe and Denmark from the past, present and future total air pollution levels as well as the contribution from the major anthropogenic emission sectors. The EVA system was applied using the hemispheric chemistry-transport model, the Danish Eulerian Hemispheric Model (DEHM), with nesting capability for higher resolution over Europe (50 km x 50 km) and Northern Europe (16.7 km x 16.7 km). In this study an Urban Background Model (UBM) has been further developed to cover the whole of Denmark with a 1 km x 1 km resolution and the model has been implemented as a part of the integrated model system, EVA. The EVA system is based on the impact-pathway methodology. The site-specific emissions will result (via atmospheric transport and chemistry) in a concentration distribution, which together with detailed population data, are used to estimate the population-level exposure. Using exposure-response functions and economic valuations, the exposure is transformed into impacts on human health and related external costs. In this study

    A social epidemiologic perspective considers factors at multiple levels of influence (e.g., social networks, neighborhoods, states) that may individually or jointly affect health and health behaviour. This provides a useful lens through which to understand the production of health behaviours in general, and drug use in particular. However, the analytic models that are commonly applied in population health sciences limit the inference we are able to draw about the determination of health behaviour by factors, likely interrelated, across levels of influence. Complex system dynamic modelling techniques may be useful in enabling the adoption of a social epidemiologic approach in health behaviour and drug use research. We provide an example of a model that aims to incorporate factors at multiple levels of influence in understanding drug dependence. We conclude with suggestions about future directions in the field and how such models may serve as virtual laboratories for policy experiments aimed at improving health behaviour. PMID:18930649

    Background: Many experts believe that the “health houses” of Iran have had major effects in increasing health status of Iranian rural community. One of the factors, which was critical to this success is the employment of young women and men from rural communities who serve as multipurpose health workers. They participate in a two-year task-oriented training course. Objectives: The purpose of this article was to describe the model of training behvarzes as the community health workers who deliver health services to the health houses of Iran. This description included the specific method of recruiting these CHWs, strategies and methods of their training which is different from general academic education. Materials and Methods: A descriptive study design was utilized for this analysis in six areas. These areas have been selected according to the expert opinions and experiences of the Center for Health Networks Management. Results: The results showed the specific method of student selection and clear objectives and standards of training related to the health needs of the community. Recruitment of native human resources, the relationship between training and performance are the characteristics, which have been made this system more efficient and responsive to the health system needs. Conclusions: Development of the job and task analysis to ensure providing the right training needs, applying more evidences through different studies for reforms, more decentralized equipped system with decision-making tools have been proposed for development.

    The HiT profiles are country-based reports that provide a detailed description of a health system and of policy initiatives in progress or under development. HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems; describe the institutional framework, process, content and implementation of health and health care policies; and highlight challenges and areas that require more in-depth analysis. The Ukrainian health system has preserved the fundamental features of the Soviet Semashko system against a background of other changes, which are developed on market economic principles. The transition from centralized financing to its extreme decentralization is the main difference in the health system in comparison with the classic Soviet model. Health facilities are now functionally subordinate to the Ministry of Health, but managerially and financially answerable to the regional and local self-government, which has constrained the implementation of health policy and fragmented health financing. Health care expenditure in Ukraine is low by regional standards and has not increased significantly as a proportion of gross domestic product (GDP) since the mid 1990s; expenditure cannot match the constitutional guarantees of access to unlimited care. Although prepaid schemes such as sickness funds are growing in importance, out-of-pocket payments account for 37.4% of total health expenditure. The core challenges for Ukrainian health care therefore remain the ineffective protection of the population from the risk of catastrophic health care costs and the structural inefficiency of the health system, which is caused by the inefficient system of health care financing. Health system weaknesses are highlighted by increasing rates of avoidable mortality. Recent political impasse has complicated health system reforms and policy-makers face significant challenges in overcoming popular distrust and

    The core problem with the US health care system is -- it already costs to much and the rate of its cost growth is cause for further alarm. To deal with these, regulators must introduce incentives for health care providers to reduce costs and introduce incentives that make consumers of health care services concerned about the costs of the services they demand. Achievement of these regulatory goals will create opportunities for the introduction of innovations, including revolutionary new technology, that can lead to major reductions in costs. Modeling of health care system inputs, outputs, transactions, and the relationships between these parameters will expedite the development of an effective regulatory process. This model must include all of those major factors that affect the demand for health care and it must facilitate benchmarking health care subsystems against the most efficient international practices.

    Differences in disease patterns and living circumstances should play no role in the quality of oral health care or in dentists' role in directing this care. Such differences, however, very likely suggest that the delivery model that works in many circumstances may not be best in all. The Alaska Tribal Health System Dental Health Aide Therapist (DHAT) model is one alternative whose potential is being evaluated. These teams are managed by dentists and have several features in common with general practice residency training programs. Alaska dentists supervising DHATs customize their practice protocols based on the skills of the therapists and the needs of the communities served. The emphasis of therapists is on prevention and basic oral health services, leaving the dentists to focus on higher level treatment that better uses the skills for which they have been trained. The characteristics of effective dentist team managers and the economic and social realities of this program are discussed. PMID:22856051

    In the last decade, health providers have implemented information systems to improve accuracy in medical diagnosis and decision-making. This article evaluates the impact of an electronic health record on emergency department physicians' diagnosis and admission decisions. A decision analytic approach using a decision tree was constructed to model the admission decision process to assess the added value of medical information retrieved from the electronic health record. Using a Bayesian statistical model, this method was evaluated on two coronary artery disease scenarios. The results show that the cases of coronary artery disease were better diagnosed when the electronic health record was consulted and led to more informed admission decisions. Furthermore, the value of medical information required for a specific admission decision in emergency departments could be quantified. The findings support the notion that physicians and patient healthcare can benefit from implementing electronic health record systems in emergency departments. PMID:26033468

    Indoor air quality effects on human health are of increasing concern to public health agencies and building owners. The prevention and treatment of 'sick building' syndrome and the spread of air-borne diseases in hospitals, for example, are well known priorities. However, increasing attention is being directed to the vulnerability of our public buildings/places, public security and national defense facilities to terrorist attack or the accidental release of air-borne biological pathogens, harmful chemicals, or radioactive contaminants. The Indoor Air Nuclear, Biological, and Chemical Health Modeling and Assessment System (IA-NBC-HMAS) was developed to serve as a health impact analysis tool for use in addressing these concerns. The overall goal was to develop a user-friendly fully functional prototype Health Modeling and Assessment system, which will operate under the PNNL FRAMES system for ease of use and to maximize its integration with other modeling and assessment capabilities accessible within the FRAMES system (e.g., ambient air fate and transport models, water borne fate and transport models, Physiologically Based Pharmacokinetic models, etc.). The prototype IA-NBC-HMAS is designed to serve as a functional Health Modeling and Assessment system that can be easily tailored to meet specific building analysis needs of a customer. The prototype system was developed and tested using an actual building (i.e., the Churchville Building located at the Aberdeen Proving Ground) and release scenario (i.e., the release and measurement of tracer materials within the building) to ensure realism and practicality in the design and development of the prototype system. A user-friendly "demo" accompanies this report to allow the reader the opportunity for a "hands on" review of the prototype system's capability.

    This analysis of the Ukrainian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. Since the country gained independence from the Soviet Union in 1991, successive governments have sought to overcome funding shortfalls and modernize the health care system to meet the needs of the population's health. However, no fundamental reform of the system has yet been implemented and consequently it has preserved the main features characteristic of the Semashko model; there is a particularly high proportion of total health expenditure paid out of pocket (42.3 % in 2012), and incentives within the system do not focus on quality or outcomes. The most recent health reform programme began in 2010 and sought to strengthen primary and emergency care, rationalize hospitals and change the model of health care financing from one based on inputs to one based on outputs. Fundamental issues that hampered reform efforts in the past re-emerged, but conflict and political instability have proved the greatest barriers to reform implementation and the programme was abandoned in 2014. More recently, the focus has been on more pressing humanitarian concerns arising from the conflict in the east of Ukraine. It is hoped that greater political, social and economic stability in the future will provide a better environment for the introduction of deep reforms to address shortcomings in the Ukrainian health system.

    2015-12-01

    Airborne desert dust is a human health problem in much of the world. While controlling emissions from arid lands is problematic, advances in remote sensing and modeling have matured sufficiently to reduce risks of exposure. Active dust sources are identified and monitored from space-based platforms and from modeled back-trajectories. Satellite-based sensors detect and monitor airborne dust crossing oceans and circling the globe. High-resolution dust forecasts and simulations over the U.S. southwest have been successfully demonstrated. Operational dust forecast systems could warn of intercontinental dust movements and potential dust exposure hazards on spatial scales of a few kilometers and on time scales sufficient for planning and avoiding risks. This paper will show how the World Meteorological Organization's Sand and Dust Storm Warning Advisory and Assessment System could coordinate international collaboration for a worldwide Dust/Health Early Warning System modeled after the decades-long success of the international Famine Early Warning System.

  10. Structured pluralism: towards an innovative model for health system reform in Latin America.

    Health systems throughout the world are searching for better ways of responding to present and future challenges. Latin America is no exception in this innovative process. Health systems in this region have to face a dual challenge: on the one hand, they must deal with a backlog of accumulated problems characteristic of underdeveloped societies; on the other hand, they are already facing a set of emerging problems characteristic of industrialized countries. This paper aims at analyzing the performance of current health systems in Latin America, while proposing an innovative model to promote equity, quality, and efficiency. We first develop a conceptualization of health systems in terms of the relationships between populations and institutions. In order to meet population needs, health systems must perform four basic functions. Two of these-financing and delivery-are conventional functions performed by every health system. The other two have often been carried out only in an implicit way or not at all. These neglected functions are 'modulation' (a broader concept than regulation, which involves setting transparent and fair rules of the game) and 'articulation' (which makes it possible to organize and manage a series of transactions among members of the population, financing agencies, and providers so that resources can flow into the production and consumption of services). Based on this conceptual framework, the paper offers a classification of current health system models in Latin America. The most frequent one, the segmented model, is criticized because it segregates the different social groups into three segments: the ministry of health, the social security institute(s), and the private sector. Each of these is vertically integrated, so that it performs all functions but only for a particular group. As an alternative, we propose a model of 'structured pluralism', which would turn the current system around by organizing it according to functions rather than social

    Italy is the sixth largest country in Europe and has the second highest average life expectancy, reaching 79.4 years for men and 84.5 years for women in 2011. There are marked regional differences for both men and women in most health indicators, reflecting the economic and social imbalance between the north and south of the country. The main diseases affecting the population are circulatory diseases, malignant tumours and respiratory diseases. Italy's health care system is a regionally based national health service that provides universal coverage largely free of charge at the point of delivery. The main source of financing is national and regional taxes, supplemented by copayments for pharmaceuticals and outpatient care. In 2012, total health expenditure accounted for 9.2 percent of GDP (slightly below the EU average of 9.6 percent). Public sources made up 78.2 percent of total health care spending. While the central government provides a stewardship role, setting the fundamental principles and goals of the health system and determining the core benefit package of health services available to all citizens, the regions are responsible for organizing and delivering primary, secondary and tertiary health care services as well as preventive and health promotion services. Faced with the current economic constraints of having to contain or even reduce health expenditure, the largest challenge facing the health system is to achieve budgetary goals without reducing the provision of health services to patients. This is related to the other key challenge of ensuring equity across regions, where gaps in service provision and health system performance persist. Other issues include ensuring the quality of professionals managing facilities, promoting group practice and other integrated care organizational models in primary care, and ensuring that the concentration of organizational control by regions of health-care providers does not stifle innovation.

    Since the successful transition to a freely elected parliament and a market economy after 1989, Poland is now a stable democracy and is well represented within political and economic organizations in Europe and worldwide. The strongly centralized health system based on the Semashko model was replaced with a decentralized system of mandatory health insurance, complemented with financing from state and territorial self-government budgets. There is a clear separation of health care financing and provision: the National Health Fund (NFZ) the sole payer in the system is in charge of health care financing and contracts with public and non-public health care providers. The Ministry of Health is the key policy-maker and regulator in the system and is supported by a number of advisory bodies, some of them recently established. Health insurance contributions, borne entirely by employees, are collected by intermediary institutions and are pooled by the NFZ and distributed between the 16 regional NFZ branches. In 2009, Poland spent 7.4% of its gross domestic product (GDP) on health. Around 70% of health expenditure came from public sources and over 83.5% of this expenditure can be attributed to the (near) universal health insurance. The relatively high share of private expenditure is mostly represented by out-of-pocket (OOP) payments, mainly in the form of co-payments and informal payments. Voluntary health insurance (VHI) does not play an important role and is largely limited to medical subscription packages offered by employers. Compulsory health insurance covers 98% of the population and guarantees access to a broad range of health services. However, the limited financial resources of the NFZ mean that broad entitlements guaranteed on paper are not always available. Health care financing is overall at most proportional: while financing from health care contributions is proportional and budgetary subsidies to system funding are progressive, high OOP expenditures

    Based on the principles of primary health care as outlined by WHO at the Alma Ata Conference in 1978, many voluntary organizations in India have been formulating, organizing and experimenting with the comprehensive rural community health Schemes. The goal is to indentify the felt needs at both individual and community levels and facilitate direct participation in decision making, develop suitable alternative, ecologically Sound indigenous models for socioeconomic well-being. In this context the Indian system of medicine has a useful and complementary role to play in the preventive and curative aspects of primary health care programmes. With the above objectives in mind the investigators undertook a brief survey of a “comprehensive rural health” project. The primary aim of this project is to develop a community health care model using innovative alternative methods using Indian indigenous system of medicine and participatory research techniques to improve rural health services of the surrounding under privileged villages. Many gaps exist in the assessment, however, a birds eye-view is presented here. PMID:22557645

    2015-04-01

    We have developed an integrated health impact assessment system EVA (Economic Valuation of Air pollution; Brandt et al., 2013a; 2013b), based on the impact-pathway chain, to assess the health impacts and health-related economic externalities of air pollution resulting from specific emission sources or sectors. The system is used to support policymaking with respect to emission control. The EVA system has previously been used to assess the health impacts based on results from a regional model DEHM (the Danish Eulerian Hemispheric Model; Brandt et al., 2012). In this study we have used a coupling of two chemistry transport models to calculate the air pollution concentration at different scales; the DEHM model to calculate the air pollution levels with a resolution down to 5.6 km x 5.6 km and the UBM model (Urban Background Model ; Berkowicz, 2000; Brandt et al., 2001) to further calculate the air pollution at 1 km x 1 km resolution for Denmark using results from DEHM as boundary conditions. Both the emission data based on the SPREAD model (Plejdrup and Gyldenkærne, 2011) as well as the population density has been represented in the model system with the same high resolution. The new developments of the integrated model system will be presented as well as results for health impacts and related external costs over the years 2006-2014 for Denmark. Furthermore, a sensitivity study of the health impact using coarse and fine resolutions in the model system has been carried out to evaluate the effect of improved description of the geographical population distribution with respect to location of local emissions.

We have developed the Clinical Adoption Meta-Model (CAMM) to help describe processes and possible challenges with clinical adoption. The CAMM, developed through an action research study to evaluate a provincial HIS, is a temporal model with four dimensions: availability, use, behaviour changes, and outcome changes. Seven CAMM archetypes are described, illustrating classic trajectories of adoption of HISs over time. Each archetype includes an example from the literature. The CAMM and its archetypes can support HIS implementers, evaluators, learners, and researchers. PMID:24884588

    Objectives The prominence given to universal implementation of electronic health record (EHR) systems in U.S. health care reform, underscores the importance of devising reliable measures of factors that predict medical care providers’ use of EHRs. This paper presents an easily administered provider survey instrument that includes measures corresponding to core dimensions of DeLone and McClean’s (D & M) model of information system success. Methods Study data came from self-administered surveys completed by 460 primary care providers, who had recently begun using an EHR. Results Based upon assessment of psychometric properties of survey items, a revised D&M causal model was formulated that included four measures of the determinants of EHR use (system quality, IT support, ease of use, user satisfaction) and five indicators of provider beliefs about the impact on an individual’s clinical practice. A structural equation model was estimated that demonstrated a high level of inter-correlation between the four scales measuring determinants of EHR use. All four variables had positive association with each of the five individual impact measures. Consistent with our revised D&M model, the association of system quality and IT support with the individual impact measures was entirely mediated by ease of use and user satisfaction. Conclusions Survey research provides important insights into provider experiences with EHR. Additional studies are in progress to investigate how the variables constructed for this study are related to direct measures of EHR use. PMID:23874357

    Today's dynamic health care environment is exceedingly complex, and health care facilities across the United States are struggling to respond to changes in technology, health care reimbursement, the Affordable Care Act, and the much-anticipated nursing shortage. Mergers, acquisitions, and integrations are the current health care reality. These are proposed to increase efficiency, efficacy, quality, satisfaction, and safety while effectively reducing cost to the consumer and stabilizing the economy of the health care system. Many of these projects fail to achieve objectives, even years after the formal change in status. Clinical education departments in merged organizations are often operated in the single-facility mindset, or contain an element of the shared services model. They are not truly integrated. Development of skills in complex analysis of current state, identification of desired scope of service and expectations of performance, and articulation of the benefits of the desired future state are all essential to nursing executive practice. This article describes an experience integrating 3 legacy education departments across 21 facilities into a centralized education system. The complexity of integration activities is illustrated and outcome measures of success are discussed. Barriers, facilitators, and risks of the project are identified and evaluated. PMID:27584894

    Hungary has achieved a successful transition from an overly centralized, integrated Semashko-style health care system to a purchaser provider split model with output-based payment methods. Although there have been substantial increases in life expectancy in recent years among both men and women, many health outcomes remain poor, placing Hungary among the countries with the worst health status and highest rate of avoidable mortality in the EU (life expectancy at birth trailed the EU27 average by 5.1 years in 2009). Lifestyle factors especially the traditionally unhealthy Hungarian diet, alcohol consumption and smoking play a very important role in shaping the overall health of the population.In the single-payer system, the recurrent expenditure on health services is funded primarily through compulsory, non-risk-related contributions made by eligible individuals or from the state budget. The central government has almost exclusive power to formulate strategic direction and to issue and enforce regulations regarding health care. In 2009 Hungary spent 7.4% of its gross domestic product (GDP) on health, with public expenditure accounting for 69.7% of total health spending, and with health expenditure per capita ranking slightly above the average for the new EU Member States, but considerably below the average for the EU27 in 2008. Health spending has been unstable over the years, with several waves of increases followed by longer periods of cost-containment and budget cuts. The share of total health expenditure attributable to private sources has been increasing, most of it accounted for by out-of-pocket (OOP) expenses. A substantial share of the latter can be attributed to informal payments, which are a deeply rooted characteristic of the Hungarian health system and a source of inefficiency and inequity. Voluntary health insurance, on the other hand, amounted to only 7.4% of private and 2.7% of total health expenditure in 2009. Revenue sources for health have been

    Health-related quality of life (HRQOL) is a person-centered concept. The analysis of HRQOL is highly relevant in the aged population, which is generally suffering from health decline. Starting from a conceptual dynamic systems model that describes the development of HRQOL in individuals over time, this study aims to develop and test a quantitative dynamic systems model, in order to reveal the possible dynamic trends of HRQOL among older adults. The model is tested in different ways: first, with a calibration procedure to test whether the model produces theoretically plausible results, and second, with a preliminary validation procedure using empirical data of 194 older adults. This first validation tested the prediction that given a particular starting point (first empirical data point), the model will generate dynamic trajectories that lead to the observed endpoint (second empirical data point). The analyses reveal that the quantitative model produces theoretically plausible trajectories, thus providing support for the calibration procedure. Furthermore, the analyses of validation show a good fit between empirical and simulated data. In fact, no differences were found in the comparison between empirical and simulated final data for the same subgroup of participants, whereas the comparison between different subgroups of people resulted in significant differences. These data provide an initial basis of evidence for the dynamic nature of HRQOL during the aging process. Therefore, these data may give new theoretical and applied insights into the study of HRQOL and its development with time in the aging population. PMID:26604722

    Well designed large systems include many instrument taking data. These data are used in a variety of ways. They are used to control the system and its components, to monitor system and component health, and often for historical or financial purposes. This paper discusses a new method of using data from low level instrumentation to monitor system and component health. The method uses the covariance of instrument outputs to calculate a measure of system change. The method involves no complicated modeling since it is not a parameter estimation algorithm. The method is iterative and can be implemented on a computer in real time. Examples are presented for a metal lathe and a high efficiency particulate air (HEPA) filter. It is shown that the proposed method is quite sensitive to system changes such as wear out and failure. The method is useful for low level system diagnostics and fault detection.

    In a mobile health management system, mobile devices act as the application hosting devices for personal health records (PHRs) and the healthcare servers construct to exchange and analyze PHRs. One of the most popular PHR standards is continuity of care record (CCR). The CCR is expressed in XML formats. However, parsing is an expensive operation that can degrade XML processing performance. Hence, the objective of this study was to identify different operational and performance characteristics for those CCR parsing models including the XML DOM parser, the SAX parser, the PULL parser, and the JSON parser with regard to JSON data converted from XML-based CCR. Thus, developers can make sensible choices for their target PHR applications to parse CCRs when using mobile devices or servers with different system resources. Furthermore, the simulation experiments of four case studies are conducted to compare the parsing performance on Android mobile devices and the server with large quantities of CCR data.

    We propose that executive dysfunction is an important component relating the socioeconomic status gradient of select health behaviors. We review and find evidence supporting an SES gradient associated with (1) negative health behaviors (e.g., obesity, excessive use of alcohol, tobacco and other substances), and (2) executive dysfunction. Moreover, the evidence supports that stress and insufficient cognitive resources contribute to executive dysfunction and that executive dysfunction is evident among individuals who smoke cigarettes, are obese, abuse alcohol, and use illicit drugs. Collectively these data supports the dual system model of cognitive control, referred to here as the Competing Neurobehavioral Decision Systems hypothesis. The implications of these relationships for intervention and social justice considerations are discussed. PMID:25008219

    Model-based reasoning techniques hold much promise in providing comprehensive monitoring and diagnostics capabilities for complex systems. We are exploring the use of one of these techniques, which utilizes multi-signal modeling and the TEAMS-RT real-time diagnostic engine, on the UH-60 Rotorcraft Aircrew Systems Concepts Airborne Laboratory (RASCAL) flight research aircraft. We focus on the engine and transmission systems, and acquire sensor data across the 1553 bus as well as by direct analog-to-digital conversion from sensors to the QHuMS (Qualtech health and usage monitoring system) computer. The QHuMS computer uses commercially available components and is rack-mounted in the RASCAL facility. A multi-signal model of the transmission and engine subsystems enables studies of system testability and analysis of the degree of fault isolation available with various instrumentation suites. The model and examples of these analyses will be described and the data architectures enumerated. Flight tests of this system will validate the data architecture and provide real-time flight profiles to be further analyzed in the laboratory.

    Background: Given the rapid pace of changes in community health needs and the mission of healthcare organizations to provide and promote the community’s health, the growing need to increase health system responsiveness to people as a key element of observance and fulfillment of justice is felt more than ever. Objectives: This study was aimed at designing the native model of responsiveness for Iran and to validate the aspects of the proposed model. Materials and Methods: Our study had a cross-sectional design and was a validation study performed in 2014. In order to define and identify responsiveness model aspects, the first phase recorded the views of 200 key informants from 19 provinces of Iran. Snowball sampling was used to select experts (based on WHO guideline). Then, the opinions of 18 comments were received from service recipients in the form of three focus group discussions and were analyzed by the frame framework analysis (interviewed recipients were selected using the purposive sampling method). Finally, in order to confirm the model’s efficacy, a responsiveness questionnaire with 7 aspects (domains) and 52 indicators (items) obtained from the initial proposed model was answered by 600 members of the selected families in the two provinces of Fars and Yazd. A multi-stage cluster sampling approach was used for the household survey. The results were analyzed by the Confirmatory Factor Analysis (CFA) test and through the use of Lisrel software. Results: Confirmatory Factor Analysis, based on the results of the key informant survey and group discussions, showed that according to quantities of GFI = 0.91, CFI = 0.93, NFI = 0.91, RMSEA = 0.074, SRMR = 0.061 and Hoelter (CN) = 178.54 in outpatient services and where GFI = 0.89, CFI = 0.91, NFI = 0.86, RMSEA = 0.064, SRMR = 0.053 and Hoelter (CN) = 158.93 for inpatient services, seven factors (F) (dignity, informed choice, confidentiality, patient training and informing, access to services, quality of basic

    Physician educators have been charged with incorporating systems-based approaches into medical education and residency training to help future physicians understand how their ability to provide high-quality health care depends on other individual and organizational stakeholders with whom and, in some cases, for whom they work. In part, this also requires that physicians accept that they have responsibilities to various system stakeholders. These changes are controversial because some fear they might distract physicians from their primary ethical obligation to their patients. However, systems theories and their applications in organizational management and business ethics support the notions that individuals can maintain primary professional ethical obligations while working within complex systems and that organizational systems can be constructed to support individual professional practice. If physicians are to commit to working within and, ultimately, improving systems of care as part of their ethical practice of medicine, then they will need a new mental model. Leading thinkers have used various models of systems and have highlighted different aspects of systems theories in describing organizations, groups of organizations, and organizational processes. This essay draws from these models some basic concepts and elements and introduces a simple but comprehensive mental model of systems for physicians. If it is used with professionalism and moral imagination, physicians might have a tool that they can use to understand, work with, and, ultimately, improve the systems of care that they rely on in their practice of medicine and that critically affect the welfare of their patients.

    Adolescents are less motivated to seek medical care for various reasons. Within the military health care system, access barriers, although less encountered, can still be a burden not only to the adolescent, but also the school system. This article describes the development of a school-based health center within a school district on a military installation. The school clinic was created by adolescent medicine specialists to maximize access to care. Students of adolescent age utilized the clinic for evaluation of acute and chronic conditions, preventative services, preparticipation evaluation, and other general complaints. After receiving signed consent forms, 30% of students were eligible for health care. There was minimal cost to initiate the service. Development of school-based health center programs at other military installations could potentially improve the status of the military health system during a time of high stress among military dependents.

    Improving health outcomes relies on patients' full engagement in prevention, decision-making, and self-management activities. Health literacy, or people's ability to obtain, process, communicate, and understand basic health information and services, is essential to those actions. Yet relatively few Americans are proficient in understanding and acting on available health information. We propose a Health Literate Care Model that would weave health literacy strategies into the widely adopted Care Model (formerly known as the Chronic Care Model). Our model calls for first approaching all patients with the assumption that they are at risk of not understanding their health conditions or how to deal with them, and then subsequently confirming and ensuring patients' understanding. For health care organizations adopting our model, health literacy would then become an organizational value infused into all aspects of planning and operations, including self-management support, delivery system design, shared decision-making support, clinical information systems to track and plan patient care, and helping patients access community resources. We also propose a measurement framework to track the impact of the new Health Literate Care Model on patient outcomes and quality of care. PMID:23381529

    The Inductive Monitoring System (IMS) software was developed to provide a technique to automatically produce health monitoring knowledge bases for systems that are either difficult to model (simulate) with a computer or which require computer models that are too complex to use for real time monitoring. IMS uses nominal data sets collected either directly from the system or from simulations to build a knowledge base that can be used to detect anomalous behavior in the system. Machine learning and data mining techniques are used to characterize typical system behavior by extracting general classes of nominal data from archived data sets. IMS is able to monitor the system by comparing real time operational data with these classes. We present a description of learning and monitoring method used by IMS and summarize some recent IMS results.

    The Health Systems in Transition (HiT) profiles are country-based reports that provide a detailed description of a health system and of policy initiatives in progress or under development. HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems; describe the institutional framework, process, content and implementation of health and health care policies; and highlight challenges and areas that require more in-depth analysis. The health status of the Greek population has strongly improved over the last few decades and seems to compare relatively favourably with other OECD and European Union (EU) countries. The health system is a mixture of public integrated, public contract and public reimbursement models, comprising elements from both the public and private sectors and incorporating principles of different organizational patterns. Access to services is based on citizenship as well as on occupational status.The system is financed by the state budget, social insurance contributions and private payments.The largest share of health expenditure constitutes private expenditure, mainly in the form of out of pocket payments which is also the element contributing most to the overall increase in health expenditure. The delivery of health care services is based on both public and private providers. The presence of private providers is more obvious in primary care,especially in diagnostic technologies, private physicians' practices and pharmaceuticals. Despite success in improving the health of the population, the Greek health care system faces serious structural problems concerning the organization, financing and delivery of services. It suffers from the absence of cost-containment measures and defined criteria for funding, resulting in sickness funds experiencing economic constraints and budget deficits. The high percentage of private expenditure goes against the principle of fair

  13. The Canadian health care system: a model for American to emulate?

    The American health care system has the world's highest per capita costs and over 30 million citizens uninsured. The neighbouring Canadian system provides coverage for all basic medical and hospital services, at costs per capita that are about US$700 lower. Single-agency public funding allows tighter control of Canadian expenditures, and reduces administrative overheads. Hospitals are run as non-profit private corporations, funded primarily by a fixed annual allocation for operating costs. Most physicians are in private fee-for-service practice, but cannot charge more than the insured tariff negotiated between their provincial government and medical association. This approach, while attractive in its decentralization, tends to separate the funding and management of clinical services. Thus, hospital information systems lag a decade behind the USA, managed care initiatives are few, health maintenance organisations do not exist, and experimentation with alternative funding or delivery systems has been sporadic. Strengths of the system compared to the USA include: higher patient satisfaction, universal coverage, slightly better cost containment, higher hospital occupancy rates, and reduction in income-related rationing with more equitable distribution of services. Weaknesses in common with the United States are: cost escalation consistently outstripping the consumer price index with costs per capita second highest in the world, ever rising consumption of services per capita, inadequate manpower planning and physician maldistribution, poor regional co-ordination of services, inadequate quality assurance and provider frustration. Additional weaknesses include: an emerging funding crisis caused by the massive federal deficit, less innovation in management and delivery of care as compared to the USA, implicit rationing with long waiting lists for some services, and recurrent provider-government conflicts that have reduced goodwill among stakeholders. Thus, while the

    This analysis of the Slovene health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. The health of the population has improved over the last few decades. While life expectancy for both men and women is similar to EU averages, morbidity and mortality data show persistent disparities between regions, and mortality from external causes is particularly high. Satisfaction with health care delivery is high, but recently waiting times for some outpatient specialist services have increased. Greater focus on preventive measures is also needed as well as better care coordination, particularly for those with chronic conditions. Despite having relatively high levels of co-payments for many services covered by the universal compulsory health insurance system, these expenses are counterbalanced by voluntary health insurance, which covers 95% of the population liable for co-payments. However, Slovenia is somewhat unique among social health insurance countries in that it relies almost exclusively on payroll contributions to fund its compulsory health insurance system. This makes health sector revenues very susceptible to economic and labour market fluctuations. A future challenge will be to diversify the resource base for health system funding and thus bolster sustainability in the longer term, while preserving service delivery and quality of care. Given changing demographics and morbidity patterns, further challenges include restructuring the funding and provision of long-term care and enhancing health system efficiency through reform of purchasing and provider-payment systems.

    Abstract Developing zebrafish embryos were used as a model system for high school students to conduct scientific investigations that reveal features of normal development and to test how different environmental toxicants impact the developmental process. The primary goal of the module was to engage students from a wide range of socio-economic backgrounds, with particular focus on underserved inner-city high schools, in inquiry-based learning and hands-on experimentation. In addition, the module served as a platform for both teachers and students to design additional inquiry-based experiments. In this module, students spawned adult zebrafish to generate developing embryos, exposed the embryos to various toxicants, then gathered, and analyzed data obtained from control and experimental embryos. The module provided a flexible, experimental framework for students to test the effects of numerous environmental toxicants, such as ethanol, caffeine, and nicotine, on the development of a model vertebrate organism. Students also observed the effects of dose on experimental outcomes. From observations of the effects of the chemical agents on vertebrate embryos, students drew conclusions on how these chemicals could impact human development and health. Results of pre-tests and post-tests completed by participating students indicate statistically significant changes in awareness of the impact of environmental agents on fish and human beings In addition, the program's evaluator concluded that participation in the module resulted in significant changes in the attitude of students and teachers toward science in general and environmental health in particular.

    Since becoming independent, Kazakhstan has undertaken major efforts in reforming its post-Soviet health system. Two comprehensive reform programmes were developed in the 2000s: the National Programme for Health Care Reform and Development 2005-2010 and the State Health Care Development Programme for 2011-2015 Salamatty Kazakhstan. Changes in health service provision included a reduction of the hospital sector and an increased emphasis on primary health care. However, inpatient facilities continue to consume the bulk of health financing. Partly resulting from changing perspectives on decentralization, levels of pooling kept changing. After a spell of devolving health financing to the rayon level in 2000-2003, beginning in 2004 a new health financing system was set up that included pooling of funds at the oblast level, establishing the oblast health department as the single-payer of health services. Since 2010, resources for hospital services under the State Guaranteed Benefits Package have been pooled at the national level within the framework of implementing the Concept on the Unified National Health Care System. Kazakhstan has also embarked on promoting evidence-based medicine and developing and introducing new clinical practice guidelines, as well as facility-level quality improvements. However, key aspects of health system performance are still in dire need of improvement. One of the key challenges is regional inequities in health financing, health care utilization and health outcomes, although some improvements have been achieved in recent years. Despite recent investments and reforms, however, population health has not yet improved substantially. PMID:22894852

    This analysis of the Latvian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health-system performance. Latvia has been constantly reforming its health system for over two decades. After independence in 1991, Latvia initially moved to create a social health insurance type system. However, problems with decentralized planning and fragmented and inefficient financing led to this being gradually reversed, and ultimately the establishment in 2011 of a National Health Service type system. These constant changes have taken place against a backdrop of relatively poor health and limited funding, with a heavy burden for individuals; Latvia has one of the highest rates of out-of-pocket expenditure on health in the European Union (EU). The lack of financial resources resulting from the financial crisis has posed an enormous challenge to the government, which struggled to ensure the availability of necessary health care services for the population and to prevent deterioration of health status. Yet this also provided momentum for reforms: previous efforts to centralise the system and to shift from hospital to outpatient care were drastically accelerated, while at the same time a social safety net strategy was implemented (with financial support from the World Bank) to protect the poor from the negative consequences of user charges. However, as in any health system, a number of challenges remain. They include: reducing smoking and cardiovascular deaths; increasing coverage of prescription pharmaceuticals; reducing the excessive reliance on out-of-pocket payments for financing the health system; reducing inequities in access and health status; improving efficiency of hospitals through implementation of DRG-based financing; and monitoring and improving quality. In the face of these challenges at a time of financial crisis, one further challenge emerges: ensuring adequate funding for the health

    2000-01-01

    "Consumer choice," "defined contribution health programs," "voucher systems," and "health marts" are variations on a theme: employees buying their own health care. This new approach to health care purchasing, which is designed to minimize the role of employers, is being proposed by an array of economists and by both Republican and Democratic legislators as the best way to address the nation's health care ills. Although enabling national legislation is unlikely to pass soon, the debate will nevertheless change the face of health care in America. The prospect is reminiscent of the debate over "Clinton Care" in 1993--although legislation was never passed, managed care rapidly came to dominate the U.S. health care system. As this reform takes hold, beneficiaries will make their own health plan selections but will have more responsibility and may bear more cost. Providers will have to adapt to new, customer-driven requirements for performance, accountability, and communications but will also find opportunities in a marketplace that they will have a major role in shaping. Physicians, health plans, and insurers should understand how these proposals will transform their role in health care. PMID:10847942

    2011-01-01

    Conceptual models have been developed to address challenges inherent in studying health information technology (HIT). This manuscript introduces an 8-dimensional model specifically designed to address the socio-technical challenges involved in design, development, implementation, use, and evaluation of HIT within complex adaptive healthcare systems. The 8 dimensions are not independent, sequential, or hierarchical, but rather are interdependent and interrelated concepts similar to compositions of other complex adaptive systems. Hardware and software computing infrastructure refers to equipment and software used to power, support, and operate clinical applications and devices. Clinical content refers to textual or numeric data and images that constitute the “language” of clinical applications. The human computer interface includes all aspects of the computer that users can see, touch, or hear as they interact with it. People refers to everyone who interacts in some way with the system, from developer to end-user, including potential patient-users. Workflow and communication are the processes or steps involved in assuring that patient care tasks are carried out effectively. Two additional dimensions of the model are internal organizational features (e.g., policies, procedures, and culture) and external rules and regulations, both of which may facilitate or constrain many aspects of the preceding dimensions. The final dimension is measurement and monitoring, which refers to the process of measuring and evaluating both intended and unintended consequences of HIT implementation and use. We illustrate how our model has been successfully applied in real-world complex adaptive settings to understand and improve HIT applications at various stages of development and implementation.

    This analysis of the German health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. In the German health care system, decision-making powers are traditionally shared between national (federal) and state (Land) levels, with much power delegated to self-governing bodies. It provides universal coverage for a wide range of benefits. Since 2009, health insurance has been mandatory for all citizens and permanent residents, through either statutory or private health insurance. A total of 70 million people or 85% of the population are covered by statutory health insurance in one of 132 sickness funds in early 2014. Another 11% are covered by substitutive private health insurance. Characteristics of the system are free choice of providers and unrestricted access to all care levels. A key feature of the health care delivery system in Germany is the clear institutional separation between public health services, ambulatory care and hospital (inpatient) care. This has increasingly been perceived as a barrier to change and so provisions for integrated care are being introduced with the aim of improving cooperation between ambulatory physicians and hospitals. Germany invests a substantial amount of its resources on health care: 11.4% of gross domestic product in 2012, which is one of the highest levels in the European Union. In international terms, the German health care system has a generous benefit basket, one of the highest levels of capacity as well as relatively low cost-sharing. However, the German health care system still needs improvement in some areas, such as the quality of care. In addition, the division into statutory and private health insurance remains one of the largest challenges for the German health care system, as it leads to inequalities. PMID:25115137

    During the last decades, guided waves have shown great potential for Structural Health Monitoring (SHM) applications. These waves can be excited and sensed by piezoelectric elements that can be permanently attached onto a structure offering online monitoring capability. As the setup of wave based SHM systems may be very difficult and time consuming there is a growing demand for efficient simulation tools providing the opportunity to design wave based SHM systems in a virtual environment. As usually high frequency waves are used, the associated short wavelength leads to the necessity of a very dense mesh, which makes conventional finite elements not well suited for this purpose. Therefore a flat shell spectral element approach is presented in this contribution. By including electromechanical coupling an SHM system can be simulated entirely from actuator voltage to sensor voltage. The focus of this contribution is the analysis of the effect of delaminations on propagating waves. A forward increment Lagrange multiplier method is used to simulate contact within the delaminated area. A model validation is performed using measured data of an anisotropic CFRP-plate.

    This analysis of the Lithuanian health system reviews the developments in organization and governance, health financing, health-care provision, health reforms and health system performance since 2000.The Lithuanian health system is a mixed system, predominantly funded from the National Health Insurance Fund through a compulsory health insurance scheme, supplemented by substantial state contributions on behalf of the economically inactive population amounting to about half of its budget. Public financing of the health sector has gradually increased since 2004 to 5.2 per cent of GDP in 2010.Although the Lithuanian health system was tested by the recent economic crisis, Lithuanias counter-cyclical state health insurance contribution policies (ensuring coverage for the economically inactive population) helped the health system to weather the crisis, and Lithuania successfully used the crisis as a lever to reduce the prices of medicines.Yet the future impact of cuts in public health spending is a cause for concern. In addition, out-of-pocket payments remain high (in particular for pharmaceuticals) and could threaten health access for vulnerable groups.A number of challenges remain. The primary care system needs strengthening so that more patients are treated instead of being referred to a specialist, which will also require a change in attitude by patients. Transparency and accountability need to be increased in resource allocation, including financing of capital investment and in the payer provider relationship. Finally, population health,albeit improving, remains a concern, and major progress can be achieved by reducing the burden of amenable and preventable mortality. PMID:23902994

    This analysis of the Icelandic health system reviews the developments in its organization and governance, health financing, health care provision, health reforms and health system performance. Life expectancy at birth is high and Icelandic men and women enjoy longer life in good health than the average European. However, Icelanders are putting on weight, more than half of adult Icelanders were overweight or obese in 2004, and total consumption of alcohol has increased considerably since 1970. The health care system is a small, state centred, publicly funded system with universal coverage, and an integrated purchaser provider relationship in which the state as payer is also the owner of most organizations providing health care services. The country's centre of clinical excellence is the University Hospital, Landspitali, in the capital Reykjavik, which alone accounts for 70 percent of the total national budget for general hospital services. However, since 1990, the health system has become increasingly characterized by a mixed economy of care and service provision, in which the number and scope of private non profit and private for profit providers has increased. While Iceland's health outcomes are some of the best among OECD countries, the health care system faces challenges involving the financial sustainability of the current system in the context of an ageing population, new public health challenges, such as obesity, and the continued impact of the country's financial collapse in 2008. The most important challenge is to change the pattern of health care utilization to steer it away from the most expensive end of the health services spectrum towards more cost efficient and effective alternatives. To a large degree, this will involve renewed attempts to prioritize primary care as the first port of call for patients, and possibly to introduce a gatekeeping function for GPs in order to moderate the use of specialist services.

HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems; describe the institutional framework, process, content and implementation of health and health care policies; and highlight challenges and areas that require more in-depth analysis. The Belgian population continues to enjoy good health and long life expectancy. This is partly due to good access to health services of high quality. Financing is based mostly on proportional social security contributions and progressive direct taxation. The compulsory health insurance is combined with a mostly private system of health care delivery, based on independent medical practice, free choice of physician and predominantly fee-for-service payment. This Belgian HiT profile (2010) presents the evolution of the health system since 2007, including detailed information on new policies. While no drastic reforms were undertaken during this period, policy-makers have pursued the goals of improving access to good quality of care while making the system sustainable. Reforms to increase the accessibility of the health system include measures to reduce the out-of-pocket payments of more vulnerable populations (low-income families and individuals as well as the chronically ill). Quality of care related reforms have included incentives to better integrate different levels of care and the establishment of information systems, among others. Additionally, several measures on pharmaceutical products have aimed to reduce costs for both the National Institute for Health and Disability Insurance (NIHDI) and patients, while maintaining the quality of care.

    This analysis of the French health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. The French population has a good level of health, with the second highest life expectancy in the world for women. It has a high level of choice of providers, and a high level of satisfaction with the health system. However, unhealthy habits such as smoking and harmful alcohol consumption remain significant causes of avoidable mortality. Combined with the significant burden of chronic diseases, this has underscored the need for prevention and integration of services, although these have not historically been strengths of the French system. Although the French health care system is a social insurance system, it has historically had a stronger role for the state than other Bismarckian social insurance systems. Public financing of health care expenditure is among the highest in Europe and out-of-pocket spending among the lowest. Public insurance is compulsory and covers the resident population; it is financed by employee and employer contributions as well as increasingly through taxation. Complementary insurance plays a significant role in ensuring equity in access. Provision is mixed; providers of outpatient care are largely private, and hospital beds are predominantly public or private non-profit-making. Despite health outcomes being among the best in the European Union, social and geographical health inequities remain. Inequality in the distribution of health care professionals is a considerable barrier to equity. The rising cost of health care and the increasing demand for long-term care are also of concern. Reforms are ongoing to address these issues, while striving for equity in financial access; a long-term care reform including public coverage of long-term care is still pending. PMID:26766545

    This analysis of the Austrian health system reviews recent developments in organization and governance, health financing, health-care provision, health reforms and health-system performance. The Austrian health system provides universal coverage for a wide range of benefits and high-quality care. Free choice of providers and unrestricted access to all care levels (general practitioners, specialist physicians and hospitals) are characteristic features of the system. Unsurprisingly, population satisfaction is well above EU average. Income-related inequality in health has increased since 2005, although it is still relatively low compared to other countries. The health-care system has been shaped by both the federal structure of the state and a tradition of delegating responsibilities to self-governing stakeholders. On the one hand, this enables decentralized planning and governance, adjusted to local norms and preferences. On the other hand, it also leads to fragmentation of responsibilities and frequently results in inadequate coordination. For this reason, efforts have been made for several years to achieve more joint planning, governance and financing of the health-care system at the federal and regional level. As in any health system, a number of challenges remain. The costs of the health-care system are well above the EU15 average, both in absolute terms and as a percentage of GDP. There are important structural imbalances in healthcare provision, with an oversized hospital sector and insufficient resources available for ambulatory care and preventive medicine. This is coupled with stark regional differences in utilization, both in curative services (hospital beds and specialist physicians) and preventative services such as preventive health check-ups, outpatient rehabilitation, psychosocial and psychotherapeutic care and nursing. There are clear social inequalities in the use of medical services, such as preventive health check-ups, immunization or dentistry

    Although comprising around 20 per cent ofAustralia's health care workforce, allied health and its contribution to improving health outcomes remains poorly understood and largely invisible in the Australian health policy and reform environment. There is strong evidence demonstrating the benefits of allied health in improving patient outcomes, minimising risk and harm from illness and improving health system efficiency and capacity to meet increased demand cost effectively. Despite this, the existing health model, funding and culture prevent us from effectively accessing these benefits at a system level. The untapped potential of allied health represents a major underutilised resource to address many of the challenges facing Australia's health system today. A transformational change in the Australian health system in how, where and by whom care is provided is necessary. Australia's health model and culture needs to shift, to genuinely involve the consumer and make fill use of all three pillars of the patient care workforce. PMID:26629583

    Israel is a small country, with just over 8 million citizens and a modern market-based economy with a comparable level of gross domestic product per capita to the average in the European Union. It has had universal health coverage since the introduction of a progressively financed statutory health insurance system in 1995. All citizens can choose from among four competing, non-profit-making health plans, which are charged with providing a broad package of benefits stipulated by the government. Overall, the Israeli health care system is quite efficient. Health status levels are comparable to those of other developed countries, even though Israel spends a relatively low proportion of its gross domestic product on health care (less than 8%) and nearly 40% of that is privately financed. Factors contributing to system efficiency include regulated competition among the health plans, tight regulatory controls on the supply of hospital beds, accessible and professional primary care and a well-developed system of electronic health records. Israeli health care has also demonstrated a remarkable capacity to innovate, improve, establish goals, be tenacious and prioritize. Israel is in the midst of numerous health reform efforts. The health insurance benefits package has been extended to include mental health care and dental care for children. A multipronged effort is underway to reduce health inequalities. National projects have been launched to measure and improve the quality of hospital care and reduce surgical waiting times, along with greater public dissemination of comparative performance data. Major steps are also being taken to address projected shortages of physicians and nurses. One of the major challenges currently facing Israeli health care is the growing reliance on private financing, with potentially deleterious effects for equity and efficiency. Efforts are currently underway to expand public financing, improve the efficiency of the public system and constrain

    Background The Inuit are an indigenous people totalling about 160,000 and living in 4 countries across the Arctic – Canada, Greenland, USA (Alaska) and Russia (Chukotka). In essence, they are one people living in 4 countries. Although there have been significant improvements in Inuit health and survival over the past 50 years, stark differences persist between the key health indicators for Inuit and those of the national populations in the United States, Canada and Russia and between Greenland and Denmark. On average, life expectancy in all 4 countries is lower for Inuit. Infant mortality rates are also markedly different with up to 3 times more infant deaths than the broader national average. Underlying these statistical differences are a range of health, social, economic and environmental factors which have affected Inuit health outcomes. Although the health challenges confronting the Inuit are in many cases similar across the Arctic, the responses to these challenges vary in accordance with the types of health systems in place in each of the 4 countries. Each of the 4 countries has a different health care system with varying degrees of accessibility and affordability for Inuit living in urban, rural and remote areas.

    In the last 20 years, demographic development in Bulgaria has been characterized by population decline, a low crude birth rate, a low fertility rate, a high mortality rate and an ageing population. A stabilizing political situation since the early 2000s and an economic upsurge since the mid-2000s were important factors in the slight increase of the birth and fertility rates and the slight decrease in standardized death rates. In general, Bulgaria lags behind European Union (EU) averages in most mortality and morbidity indicators. Life expectancy at birth reached 73.3 years in 2008 with the main three causes of death being diseases of the circulatory system, malignant neoplasms and diseases of the respiratory system. One of the most important risk factors overall is smoking, and the average standardized death rate for smoking-related causes in 2008 was twice as high as the EU15 average. The Bulgarian health system is characterized by limited statism. The Ministry of Health is responsible for national health policy and the overall organization and functioning of the health system and coordinates with all ministries with relevance to public health. The key players in the insurance system are the insured individuals, the health care providers and the third party payers, comprising the National Health Insurance Fund, the single payer in the social health insurance (SHI) system, and voluntary health insurance companies (VHICs). Health financing consists of a publicprivate mix. Health care is financed from compulsory health insurance contributions, taxes, outofpocket (OOP) payments, voluntary health insurance (VHI) premiums, corporate payments, donations, and external funding. Total health expenditure (THE) as a share of gross domestic product (GDP) increased from 5.3% in 1995 to 7.3% in 2008. At the latter date it consisted of 36.5% OOP payments, 34.8% SHI, 13.6% Ministry of Health expenditure, 9.4% municipality expenditure and 0.3% VHI. Informal payments in the health

    This analysis of the Swiss health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. The Swiss health system is highly complex, combining aspects of managed competition and corporatism (the integration of interest groups in the policy process) in a decentralized regulatory framework shaped by the influences of direct democracy. The health system performs very well with regard to a broad range of indicators. Life expectancy in Switzerland (82.8 years) is the highest in Europe after Iceland, and healthy life expectancy is several years above the European Union (EU) average. Coverage is ensured through mandatory health insurance (MHI), with subsidies for people on low incomes. The system offers a high degree of choice and direct access to all levels of care with virtually no waiting times, though managed care type insurance plans that include gatekeeping restrictions are becoming increasingly important. Public satisfaction with the system is high and quality is generally viewed to be good or very good. Reforms since the year 2000 have improved the MHI system, changed the financing of hospitals, strengthened regulations in the area of pharmaceuticals and the control of epidemics, and harmonized regulation of human resources across the country. In addition, there has been a slow (and not always linear) process towards more centralization of national health policy-making. Nevertheless, a number of challenges remain. The costs of the health care system are well above the EU average, in particular in absolute terms but also as a percentage of gross domestic product (GDP) (11.5%). MHI premiums have increased more quickly than incomes since 2003. By European standards, the share of out-of-pocket payments is exceptionally high at 26% of total health expenditure (compared to the EU average of 16%). Low and middle-income households contribute a greater share of their income to

    This analysis of the Estonian health system reviews recent developments in organization and governance, health financing, health-care provision, health reforms and health system performance. Without doubt, the main issue has been the 2008 financial crisis. Although Estonia has managed the downturn quite successfully and overall satisfaction with the system remains high, it is hard to predict the longer-term effects of the austerity package. The latter included some cuts in benefits and prices, increased cost sharing for certain services, extended waiting times, and a reduction in specialized care. In terms of health outcomes, important progress was made in life expectancy, which is nearing the European Union (EU) average, and infant mortality. Improvements are necessary in smoking and alcohol consumption, which are linked to the majority of avoidable diseases. Although the health behaviour of the population is improving, large disparities between groups exist and obesity rates, particularly among young people, are increasing. In health care, the burden of out-of-pocket payments is still distributed towards vulnerable groups. Furthermore, the number of hospitals, hospital beds and average length of stay has decreased to the EU average level, yet bed occupancy rates are still below EU averages and efficiency advances could be made. Going forwards, a number of pre-crisis challenges remain. These include ensuring sustainability of health care financing, guaranteeing a sufficient level of human resources, prioritizing patient-centred health care, integrating health and social care services, implementing intersectoral action to promote healthy behaviour, safeguarding access to health care for lower socioeconomic groups, and, lastly, improving evaluation and monitoring tools across the health system.

    Abstract In general, there is agreement that robust integrated information systems are the foundation for building successful regional health care delivery systems. Integrated Advanced Information Management System (IAIMS) institutions that, over the years, have developed strategies for creating cohesive institutional information systems and services are finding that IAIMS strategies work well in the even more complex regional environment. The key elements of IAIMS planning are described and lessons learned are discussed in the context of regional health information systems developed. The challenges of aligning the various information agencies and agendas in support of a regional health information system are complex ; however, the potential rewards for health care in quality, efficacy, and cost savings are enormous.

    Background The global burden of disease is increasingly dominated by non-communicable diseases.These diseases are less amenable to curative and preventative interventions than communicable disease. This presents a challenge to medical practice and medical research, both of which are experiencing diminishing returns from increasing investment. Objective Our aim was to (1) review how medical knowledge is generated, and its limitations, (2) assess the potential for emerging technologies and ideas to improve medical research, and (3) suggest solutions and recommendations to increase medical research efficiency on non-communicable diseases. Methods We undertook an unsystematic review of peer-reviewed literature and technology websites. Results Our review generated the following conclusions and recommendations. (1) Medical knowledge continues to be generated in a reductionist paradigm. This oversimplifies our models of disease, rendering them ineffective to sufficiently understand the complex nature of non-communicable diseases. (2) Some of these failings may be overcome by adopting a “Systems Medicine” paradigm, where the human body is modeled as a complex adaptive system. That is, a system with multiple components and levels interacting in complex ways, wherein disease emerges from slow changes to the system set-up. Pursuing systems medicine research will require larger datasets. (3) Increased data sharing between researchers, patients, and clinicians could provide this unmet need for data. The recent emergence of electronic health care records (EHR) could potentially facilitate this in real-time and at a global level. (4) Efforts should continue to aggregate anonymous EHR data into large interoperable data silos and release this to researchers. However, international collaboration, data linkage, and obtaining additional information from patients will remain challenging. (5) Efforts should also continue towards “Medicine 2.0”. Patients should be given access to

    Using a time study method, dental care treatment resources were studied concerning different caries groups of children and adolescents 3-19 years of age. The results were applied to a model for a dental health related patient group system as a tool for presenting the dental care situation. Quality assurance aspects of a dental health related patient group system, adapted for use in general dental care, had led to a suggested model system: "Dental Visiting Groups" (DVG). The DVG system takes into consideration the fact that dental care was performed by three dental care-giving personnel groups--dentists, dental hygienists and dental assistants--giving dental care in three main areas of dental procedures: diagnostic, prevention and intervention. The DVG system implied a model of Swedish dentistry in change, and presented the relationships among the dental health related patient groups, the three main areas of dental procedures, and the tasks of the dental care-givers. Applied over time, the DVG system illustrated the efficiency of the dental care model used. PMID:7676387

    The HiT reviews are country-based reports that provide a detailed description of a health system and of policy initiatives in progress or under development. HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems; describe the institutional framework, process, content and implementation of health and health care policies; and highlight challenges and areas that require more in-depth analysis. At independence from the Soviet Union in 1991, the Russian health system inherited an extensive, centralized Semashko system, but was quick to reform health financing by adopting a mandatory health insurance (MHI) model in 1993. MHI was introduced in order to open up an earmarked stream of funding for health care in the face of severe fiscal constraints. While the health system has evolved and changed significantly since the early 1990 s, the legacy of having been a highly centralized system focused on universal access to basic care remains. High energy prices on world markets have ensured greater macroeconomic stability, a budget surplus and improvements in living standards for most of the Russian population. However, despite an overall reduction in the poverty rate, there is a marked urban rural split and rural populations have worse health and poorer access to health services than urban populations. The increase in budgetary resources available to policy-makers have led to a number of recent federal-level health programmes that have focused on the delivery of services and increasing funding for priority areas including primary care provision in rural areas. Nevertheless, public health spending in the Russian Federation remains relatively low given the resources available. However, it is also clear that, even with the current level of financing, the performance of the health system could be improved.

    2015-01-01

    Most neglected tropical diseases (NTDs) have complex life cycles and are challenging to control. The “2020 goals” of control and elimination as a public health programme for a number of NTDs are the subject of significant international efforts and investments. Beyond 2020 there will be a drive to maintain these gains and to push for true local elimination of transmission. However, these diseases are affected by variations in vectors, human demography, access to water and sanitation, access to interventions and local health systems. We therefore argue that there will be a need to develop local quantitative expertise to support elimination efforts. If available now, quantitative analyses would provide updated estimates of the burden of disease, assist in the design of locally appropriate control programmes, estimate the effectiveness of current interventions and support ‘real-time’ updates to local operations. Such quantitative tools are increasingly available at an international scale for NTDs, but are rarely tailored to local scenarios. Localised expertise not only provides an opportunity for more relevant analyses, but also has a greater chance of developing positive feedback between data collection and analysis by demonstrating the value of data. This is essential as rational program design relies on good quality data collection. It is also likely that if such infrastructure is provided for NTDs there will be an additional impact on the health system more broadly. Locally tailored quantitative analyses can help achieve sustainable and effective control of NTDs, but also underpin the development of local health care systems.

    This analysis of the Romanian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. The Romanian health care system is a social health insurance system that has remained highly centralized despite recent efforts to decentralize some regulatory functions. It provides a comprehensive benefits package to the 85% of the population that is covered, with the remaining population having access to a minimum package of benefits. While every insured person has access to the same health care benefits regardless of their socioeconomic situation, there are inequities in access to health care across many dimensions, such as rural versus urban, and health outcomes also differ across these dimensions. The Romanian population has seen increasing life expectancy and declining mortality rates but both remain among the worst in the European Union. Some unfavourable trends have been observed, including increasing numbers of new HIV/AIDS diagnoses and falling immunization rates. Public sources account for over 80% of total health financing. However, that leaves considerable out-of-pocket payments covering almost a fifth of total expenditure. The share of informal payments also seems to be substantial, but precise figures are unknown. In 2014, Romania had the lowest health expenditure as a share of gross domestic product (GDP) among the EU Member States. In line with the government's objective of strengthening the role of primary care, the total number of hospital beds has been decreasing. However, health care provision remains characterized by underprovision of primary and community care and inappropriate use of inpatient and specialized outpatient care, including care in hospital emergency departments. The numbers of physicians and nurses are relatively low in Romania compared to EU averages. This has mainly been attributed to the high rates of workers emigrating abroad over the

    Denmark has a tradition of a decentralized health system. However, during recent years, reforms and policy initiatives have gradually centralized the health system in different ways. The structural reform of 2007 merged the old counties into fewer bigger regions, and the old municipalities likewise. The hospital structure is undergoing similar reforms, with fewer, bigger and more specialized hospitals. Furthermore, a more centralized approach to planning and regulation has been taking place over recent years. This is evident in the new national planning of medical specialties as well as the establishment of a nationwide accreditation system, the Danish Healthcare Quality Programme, which sets national standards for health system providers in Denmark. Efforts have also been made to ensure coherent patient pathways - at the moment for cancer and heart disease - that are similar nationwide. These efforts also aim at improving intersectoral cooperation. Financially, recent years have seen the introduction of a higher degree of activity-based financing in the public health sector, combined with the traditional global budgeting.A number of challenges remain in the Danish health care system. The consequences of the recent reforms and centralization initiatives are yet to be fully evaluated. Before this happens, a full overview of what future reforms should target is not possible. Denmark continues to lag behind the other Nordic countries in regards to some health indicators, such as life expectancy. A number of risk factors may be the cause of this: alcohol intake and obesity continue to be problems, whereas smoking habits are improving. The level of socioeconomic inequalities in health also continues to be a challenge. The organization of the Danish health care system will have to take a number of challenges into account in the future. These include changes in disease patterns, with an ageing population with chronic and long-term diseases; ensuring sufficient staffing

    Objective Depressive disorders are important causes of disease burden and are associated with substantial economic costs. Therefore, it is important to design a health care system that can effectively manage depression at sustainable costs. This paper computes the benefit-to-costs ratio of the current Dutch health care system for depression, and investigates whether offering more online preventive interventions improves the cost-effectiveness overall. Methods A health economic (Markov) model was used to synthesize clinical and economic evidence and to compute population-level costs and effects of interventions. The model compares a base-case scenario without preventive telemedicine and alternative scenarios with preventive telemedicine. The central outcome is the benefit-to-cost ratio, also known as return-on-investment (ROI). Results In terms of ROI, a health care system with preventive telemedicine for depressive disorders offers better value for money than a health care system without internet-based prevention. Overall, the ROI increases from €1.45 ($1.72) in the base-case scenario to €1.76 ($2.09) in the alternative scenario where preventive telemedicine is offered. In a scenario where the costs of offering preventive telemedicine are balanced by cutting back on the expenditure for curative interventions, ROI increases to €1.77 ($2.10), while keeping the health care budget constant. Conclusion In order for a health care system for depressive disorders to remain economically sustainable, its cost-benefit ratio needs to be improved. Offering preventive telemedicine at a large scale is likely to introduce such an improvement. PMID:23759290

    Modeling, Simulation, and Analysis are special competencies of the Department of Energy (DOE) National Laboratories which have been developed and refined through years of national defense work. Today, many of these skills are being applied to the problem of understanding the performance of medical devices and treatments. At Sandia National Laboratories we are developing models at all three levels of health care delivery: (1) phenomenology models for Observation and Test, (2) model-based outcomes simulations for Diagnosis and Prescription, and (3) model-based design and control simulations for the Administration of Treatment. A sampling of specific applications include non-invasive sensors for blood glucose, ultrasonic scanning for development of prosthetics, automated breast cancer diagnosis, laser burn debridement, surgical staple deformation, minimally invasive control for administration of a photodynamic drug, and human-friendly decision support aids for computer-aided diagnosis. These and other projects are being performed at Sandia with support from the DOE and in cooperation with medical research centers and private companies. Our objective is to leverage government engineering, modeling, and simulation skills with the biotechnical expertise of the health care community to create a more knowledge-rich environment for decision making and treatment.

    This analysis of the Dutch health system reviews recent developments in organization and governance, health financing, healthcare provision, health reforms and health system performance. Without doubt, two major reforms implemented since the mid-2000s are among the main issues today. The newly implemented long-term care reform will have to realize a transition from publicly provided care to more self-reliance on the part of the citizens and a larger role for municipalities in its organization. A particular point of attention is how the new governance arrangements and responsibilities in long-term care will work together. The 2006 reform replaced the division between public and private insurance by one universal social health insurance and introduced managed competition as a driving mechanism in the healthcare system. Although the reform was initiated almost a decade ago, its stepwise implementation continues to bring changes in the healthcare system in general and in the role of actors in particular. In terms of performance, essential healthcare services are within easy reach and waiting times have been decreasing. The basic health insurance package and compensations for lower incomes protect citizens against catastrophic spending. Out-of-pocket payments are low from an international perspective. Moreover, the Dutch rate the quality of the health system and their health as good. International comparisons show that the Netherlands has low antibiotic use, a low number of avoidable hospitalizations and a relatively low avoidable mortality. National studies show that healthcare has made major contributions to the health of the Dutch population as reflected in increasing life expectancy. Furthermore, some indicators such as the prescription of generics and length of stay reveal improvements in efficiency over the past years. Nevertheless, the Netherlands still has one of the highest per capita health expenditures in Europe, although growth has slowed considerably after

    Turkey has accomplished remarkable improvements in terms of health status in the last three decades, particularly after the implementation of the Health Transformation Program (HTP (Saglikta Donus, um Programi)). Average life expectancy reached 71.8 for men and 76.8 for women in 2010. The infant mortality rate (IMR) decreased to 10.1 per 1000 live births in 2010, down from 117.5 in 1980. Despite these achievements, there are still discrepancies in terms of infant mortality between rural and urban areas and different parts of the country, although these have been diminishing over the years. The higher infant mortality rates in rural areas can be attributed to low socioeconomic conditions, low female education levels and the prevalence of infectious diseases. The main causes of death are diseases of the circulatory system followed by malignant neoplasms. Turkeys health care system has been undergoing a far-reaching reform process (HTP) since 2003 and radical changes have occurred both in the provision and the financing of health care services. Health services are now financed through a social security scheme covering the majority of the population, the General Health Insurance Scheme (GHIS (Genel Saglik Sigortasi)), and services are provided both by public and private sector facilities. The Social Security Institution (SSI (Sosyal Guvenlik Kurumu)), financed through payments by employers and employees and government contributions in cases of budget deficit, has become a monopsonic (single buyer) power on the purchasing side of health care services. On the provision side, the Ministry of Health (Saglik Bakenligi) is the main actor and provides primary, secondary and tertiary care through its facilities across the country. Universities are also major providers of tertiary care. The private sector has increased its range over recent years, particularly after arrangements paved the way for private sector provision of services to the SSI. The most important reforms since

    Background The rising burden of disease and weak health systems are being compounded by the persistent economic downturn, re-emerging diseases, and violent conflicts. There is a growing recognition that the global health agenda needs to shift from an emphasis on disease-specific approaches to strengthening of health systems, including dealing with social, environmental, and economic determinants through multisectoral responses. Methods A review and analysis of data on strengthening health sector reform and health systems was conducted. Attention was paid to the goal of health and interactions between health sector reforms and the functions of health systems. Further, we explored how these interactions contribute toward delivery of health services, equity, financial protection, and improved health. Findings Health sector reforms cannot be developed from a single global or regional policy formula. Any reform will depend on the country's history, values and culture, and the population's expectations. Some of the emerging ingredients that need to be explored are infusion of a health systems agenda; development of a comprehensive policy package for health sector reforms; improving alignment of planning and coordination; use of reliable data; engaging ‘street level’ policy implementers; strengthening governance and leadership; and allowing a holistic and developmental approach to reforms. Conclusions The process of reform needs a fundamental rather than merely an incremental and evolutionary change. Without radical structural and systemic changes, existing governance structures and management systems will continue to fail to address the existing health problems. PMID:24560261

    This analysis of the Belarusian health system reviews the developments in organization and governance, health financing, healthcare provision, health reforms and health system performance since 2008. Despite considerable change since independence, Belarus retains a commitment to the principle of universal access to health care, provided free at the point of use through predominantly state-owned facilities, organized hierarchically on a territorial basis. Incremental change, rather than radical reform, has also been the hallmark of health-care policy, although capitation funding has been introduced in some areas and there have been consistent efforts to strengthen the role of primary care. Issues of high costs in the hospital sector and of weaknesses in public health demonstrate the necessity of moving forward with the reform programme. The focus for future reform is on strengthening preventive services and improving the quality and efficiency of specialist services. The key challenges in achieving this involve reducing excess hospital capacity, strengthening health-care management, use of evidence-based treatment and diagnostic procedures, and the development of more efficient financing mechanisms. Involving all stakeholders in the development of further reform planning and achieving consensus among them will be key to its success. PMID:24334702

    Before World War II, Czechoslovakia was among the most developed European countries with an excellent health care system. After the Communist coup d'etat in 1948, the country was forced to adapt its existing health care system to the Soviet model. It was planned and managed by the government, financed by general tax money, operated in a highly centralized, bureaucratic fashion, and provided service at no direct charge at the time of service. In recent years, the health care system had been deteriorating as the health of the people had also been declining. Life expectancy, infant mortality rates, and diseases of the circulatory system are higher than in Western European countries. In 1989, political changes occurred in Czechoslovakia that made health care reform possible. Now health services are being decentralized, and the ownership of hospitals is expected to be transferred to communities, municipalities, churches, charitable groups, or private entities. Almost all health leaders, including hospital directors and hospital department heads, have been replaced. Physicians will be paid according to the type and amount of work performed. Perhaps the most important reform is the establishment of an independent General Health Care Insurance Office financed directly by compulsory contributions from workers, employers, and government that will be able to negotiate with hospitals and physicians to determine payment for services.

    Life expectancy in Sweden is high and the country performs well in comparisons related to disease-oriented indicators of health service outcomes and quality of care. The Swedish health system is committed to ensuring the health of all citizens and abides by the principles of human dignity, need and solidarity, and cost-effectiveness. The state is responsible for overall health policy, while the funding and provision of services lies largely with the county councils and regions. The municipalities are responsible for the care of older and disabled people. The majority of primary care centres and almost all hospitals are owned by the county councils. Health care expenditure is mainly tax funded (80%) and is equivalent to 9.9% of gross domestic product (GDP) (2009). Only about 4% of the population has voluntary health insurance (VHI). User charges fund about 17% of health expenditure and are levied on visits to professionals, hospitalization and medicines. The number of acute care hospital beds is below the European Union (EU) average and Sweden allocates more human resources to the health sector than most OECD countries. In the past, the Achilles heel of Swedish health care included long waiting times for diagnosis and treatment and, more recently, divergence in quality of care between regions and socioeconomic groups. Addressing long waiting times remains a key policy objective along with improving access to providers. Recent principal health reforms over the past decade relate to: concentrating hospital services; regionalizing health care services, including mergers; improving coordinated care; increasing choice, competition and privatization in primary care; privatization and competition in the pharmacy sector; changing co-payments; and increasing attention to public comparison of quality and efficiency indicators, the value of investments in health care and responsiveness to patients needs.

    Computerised identity management is in general encountered as a low-level mechanism that enables users in a particular system or region to securely access resources. In the Electronic Health Record (EHR), the identifying information of both the healthcare professionals who access the EHR and the patients whose EHR is accessed, are subject to change. Demographics services have been developed to manage federated patient and healthcare professional identities and to support challenging healthcare-specific use cases in the presence of diverse and sometimes conflicting demographic identities. Demographics services are not the only use for identities in healthcare. Nevertheless, contemporary EHR specifications limit the types of entities that can be the actor or subject of a record to health professionals and patients, thus limiting the use of two level models in other healthcare information systems. Demographics are ubiquitous in healthcare, so for a general identity model to be usable, it should be capable of managing demographic information. In this paper, we introduce a generalised identity reference model (GIRM) based on key characteristics of five surveyed demographic models. We evaluate the GIRM by using it to express the EN13606 demographics model in an extensible way at the metadata level and show how two-level modelling can support the exchange of instances of demographic identities. This use of the GIRM to express demographics information shows its application for standards-compliant two-level modelling alongside heterogeneous demographics models. We advocate this approach to facilitate the interoperability of identities between two-level model-based EHR systems and show the validity and the extensibility of using GIRM for the expression of other health-related identities.

    Vietnam's health system consists of four levels: national, provincial/special city, prefecture/ward, and basic unit of town or village. Health care is managed by the Health Department at the national level and by the health and welfare section of the People's Committee at all other levels. Actual medical services are provided by the National Central Hospital at the national level, by general hospitals at the provincial/special city level, by general hospitals and multi-purpose health clinics at the prefecture/ward level, and by health stations at the basic unit level. Health services provide not only doctors, nurses, and pharmacists, but also paramedical staff, especially at the basic unit level. Just as with other developing countries, infectious diseases are the most important priorities in health/medical care policies; especially malaria, which is the number one priority followed by diarrhea. Because of well-established health stations at the basic unit level throughout the country and a relatively sufficient supply of medication, the mortality rate due to the above is low. The maternal/infant health care index of 1988 shows the following: low birth weight (14%); maternal mortality (1.4/1000); neonatal mortality (33.5/1000); and perinatal mortality (22.5/1000). Malnutrition of children under 3 years of age in farming areas, insufficient supply of drinking water, and lack of industrial health insurance are some of the problems yet to be solved. It is hoped that medical services can be a significant part of the comprehensive economic development program within the framework of Japan's international cooperation/assistance. PMID:8111100

    Most healthcare services use information and communication technologies to reduce and redistribute the workload associated with follow-up of chronic conditions. However, the lack of normalization of the information handled in and exchanged between such services hinders the scalability and extendibility. The use of medical standards for modelling and exchanging information, especially dual-model based approaches, can enhance the features of screening services. Hence, the approach of this paper is twofold. First, this article presents a generic methodology to model patient-centered clinical processes. Second, a proof of concept of the proposed methodology was conducted within the diabetic retinopathy (DR) screening service of the Health Service of Navarre (Spain) in compliance with a specific dual-model norm (openEHR). As a result, a set of elements required for deploying a model-driven DR screening service has been established, namely: clinical concepts, archetypes, termsets, templates, guideline definition rules, and user interface definitions. This model fosters reusability, because those elements are available to be downloaded and integrated in any healthcare service, and interoperability, since from then on such services can share information seamlessly.

    Summary Background How to finance progress towards universal health coverage in low-income and middle-income countries is a subject of intense debate. We investigated how alternative tax systems affect the breadth, depth, and height of health system coverage. Methods We used cross-national longitudinal fixed effects models to assess the relationships between total and different types of tax revenue, health system coverage, and associated child and maternal health outcomes in 89 low-income and middle-income countries from 1995–2011. Findings Tax revenue was a major statistical determinant of progress towards universal health coverage. Each US$100 per capita per year of additional tax revenues corresponded to a yearly increase in government health spending of $9·86 (95% CI 3·92–15·8), adjusted for GDP per capita. This association was strong for taxes on capital gains, profits, and income ($16·7, 9·16 to 24·3), but not for consumption taxes on goods and services (−$4·37, −12·9 to 4·11). In countries with low tax revenues (<$1000 per capita per year), an additional $100 tax revenue per year substantially increased the proportion of births with a skilled attendant present by 6·74 percentage points (95% CI 0·87–12·6) and the extent of financial coverage by 11·4 percentage points (5·51–17·2). Consumption taxes, a more regressive form of taxation that might reduce the ability of the poor to afford essential goods, were associated with increased rates of post-neonatal mortality, infant mortality, and under-5 mortality rates. We did not detect these adverse associations with taxes on capital gains, profits, and income, which tend to be more progressive. Interpretation Increasing domestic tax revenues is integral to achieving universal health coverage, particularly in countries with low tax bases. Pro-poor taxes on profits and capital gains seem to support expanding health coverage without the adverse associations with health outcomes observed for

    Norways five million inhabitants are spread over nearly four hundred thousand square kilometres, making it one of the most sparsely populated countries in Europe. It has enjoyed several decades of high growth, following the start of oil production in early 1970s, and is now one of the richest countries per head in the world. Overall, Norways population enjoys good health status; life expectancy of 81.53 years is above the EU average of 80.14, and the gap between overall life expectancy and healthy life years is around half the of EU average. The health care system is semi decentralized. The responsibility for specialist care lies with the state (administered by four Regional Health Authorities) and the municipalities are responsible for primary care. Although health care expenditure is only 9.4% of Norways GDP (placing it on the 16th place in the WHO European region), given Norways very high value of GDP per capita, its health expenditure per head is higher than in most countries. Public sources account for over 85% of total health expenditure; the majority of private health financing comes from households out-of-pocket payments.The number of practitioners in most health personnel groups, including physicians and nurses, has been increasing in the last few decades and the number of health care personnel per 100 000 inhabitants is high compared to other EU countries. However, long waiting times for elective care continue to be a problem and are cause of dissatisfaction among the patients. The focus of health care reforms has seen shifts over the past four decades. During the 1970s the focus was on equality and increasing geographical access to health care services; during the 1980s reforms aimed at achieving cost containment and decentralizing health care services; during the 1990s the focus was on efficiency. Since the beginning of the millennium the emphasis has been given to structural changes in the delivery and organization of health care and to policies

    Response time measurement of a web-based system is essential to evaluate its performance. This paper shows a comparison of the response times of a Web-based system for Ophthalmologic Electronic Health Records (EHRs), TeleOftalWeb. It makes use of different database models like Oracle 10 g, dbXML 2.0, Xindice 1.2, and eXist 1.1.1. The system's modelling, which uses Tandem Queue networks, will allow us to estimate the service times of the different components of the system (CPU, network and databases). In order to calculate those times, associated to the different databases, benchmarking techniques are used. The final objective of the comparison is to choose the database system resulting in the lowest response time to TeleOftalWeb and to compare the obtained results using a new benchmarking.

    We have recently developed a prototype SHM system consisting of smart sensors, database and MATALB servers. In preceding efforts, we demonstrated the usefulness of analyzing and publishing the data on the web. However, the effective data management and automatic analysis had not been provided. In this study, the data model for easy and flexible data management and automatic configuration of the smart sensors are proposed and their feasibility is demonstrated. In addition, an automatic analysis tool based on ARX models is introduced for practical application. The prototype SHM system is in operation for more than two months without any troubles. To incorporate many needs from different stakeholders, we formed a consortium called K-SHM last year at Keio University. At present, 16 companies joined the consortium consisting of 11 construction companies, 3 large design firms, a sensor maker and a system integration company as members. The consortium will continue improving this system for real application.

    Uzbekistan is a central Asian country that became independent in 1991 with the break-up of the Soviet Union. Since then, it has embarked on several major health reforms covering health care provision, governance and financing, with the aim of improving efficiency while ensuring equitable access. Primary care in rural areas has been changed to a two-tiered system, while specialized polyclinics in urban areas are being transformed into general polyclinics covering all groups of the urban population. Secondary care is financed on the basis of past expenditure and inputs (and increasingly self-financing through user fees), while financing of primary care is increasingly based on capitation. There are also efforts to improve allocative efficiency, with a slowly increasing share of resources devoted to the reformed primary health care system. Health care provision has largely remained in public ownership but nearly half of total health care expenditure comes from private sources, mostly in the form of out-of-pocket expenditure. There is a basic benefits package, which includes primary care, emergency care and care for certain disease and population categories. Yet secondary care and outpatient pharmaceuticals are not included in the benefits package for most of the population, and the reliance on private health expenditure results in inequities and catastrophic expenditure for households. While the share of public expenditure is slowly increasing, financial protection thus remains an area of concern. Quality of care is another area that is receiving increasing attention.

    The shrinking size and weight of electronic circuitry has given rise to a new generation of smart clothing that enables biological data to be measured and transmitted. As the variation in the number and type of deployable devices and sensors increases, technology must allow their seamless integration so they can be electrically powered, operated, and recharged over a digital pathway. Nyx Illuminated Clothing Company has developed a lightweight health monitoring system that integrates medical sensors, electrodes, electrical connections, circuits, and a power supply into a single wearable assembly. The system is comfortable, bendable in three dimensions, durable, waterproof, and washable. The innovation will allow astronaut health monitoring in a variety of real-time scenarios, with data stored in digital memory for later use in a medical database. Potential commercial uses are numerous, as the technology enables medical personnel to noninvasively monitor patient vital signs in a multitude of health care settings and applications.

    The Multimedia Environmental Pollutant Assessment System (MEPAS) provides physics-based models for human health risk assessment for radioactive and hazardous pollutants. MEPAS analyzes pollutant behavior in various media (air, soil, groundwater and surface water) and estimates transport through and between media and exposure and impacts to the environment, to the maximum individual, and to populations. MEPAS includes 25 exposure pathway models, a database with information on more than 650 contaminants, and a sensitivity module that allows for uncertainty analysis. Four major transport pathways are considered in MEPAS: groundwater, overland, surface water, and atmospheric. This report describes the exposure pathway and health impact assessment component of MEPAS, which provides an estimate of health impacts to selected individuals and populations from exposure to pollutants. The exposure pathway analysis starts with pollutant concentration in a transport medium and estimates the average daily dose to exposed individuals from contact with the transport medium or a secondary medium contaminated by the transport medium. The average daily dose is then used to estimate a measure of health impact appropriate to the type of pollutant considered. Discussions of the exposure pathway models include the assumptions and equations used to convert the transport medium concentrations to exposure medium concentrations. The discussion for a given exposure pathway defines the transport pathways leading to the exposure, the special processes considered in determining the pollutant concentration in the exposure medium, and the exposure model used to estimate the average daily dose. Models for the exposure pathway and health impact assessments require definition of several parameters. A summary of the notation used for these parameters is provided.

    The public health movement is an old discipline being given new life and meaning based on a recognition of continuing health problems associated with social inequalities. The 'new public health' movement has goals which are closely aligned to those of the World Health Organization in their Health for All by 2000 initiative which represent a collective approach to health in contrast to the current political emphasis on individual responsibility for health. Public health nursing is a relatively new concept in Britain but posts are beginning to be established in many areas where nurses are working in partnership with communities in a public health capacity. At a time when this area of nursing is in its relative infancy it is appropriate to develop a clear philosophy and framework and to examine potential strategies. This paper sets out to contribute to the development of this discipline by critically analysing the work of Betty Neuman to determine its utility for public health nursing. PMID:8132923

    The system described in this paper uses the technological advances in information technology in order to influence and improve healthcare practice by enabling the flexible modelling, direct representation and adaptable use of medical knowledge. It aims at resolving a number of difficulties encountered by current information repositories, such as costly customization, reusability, high maintenance and poor information modelling, by employing the architecture of the functional data model (FDM), while maintaining full interoperability with existing systems by means of XML. On the information-modelling front the system supports a variety of modelling techniques that are especially relevant to medical applications, such as complex objects, incomplete or missing information, partially structured data and multimedia content. A prototype implementation of the system has been developed which consists of a multimedia-enhanced version of the functional database language FDL, and a web-based, two-way translator interface between the application's native language and XML. This interface provides full interoperability with other, heterogeneous systems over the web, thus, significantly reducing the complexity of developing distributed healthcare systems and e-health applications.

    A high-resolution assessment of health impacts from air pollution and related external cost has been conducted for Denmark using the integrated EVA model system. The EVA system is based on the impact-pathway methodology, where the site-specific emissions will result, via atmospheric transport and chemistry, in a concentration distribution, which together with detailed population data, is used to estimate the population-level exposure. Using exposure-response functions and economic valuations, the exposure is transformed into impacts on human health and related external costs. In this study we have used a coupling of two chemistry transport models to calculate the air pollution concentration at different domain and scales; the Danish Eulerian Hemispheric Model (DEHM) to calculate the air pollution levels in the Northern Hemisphere with a resolution down to 5.6 km x 5.6 km and the Urban Background Model (UBM) to further calculate the air pollution in Denmark at 1 km x 1 km resolution using results from DEHM as boundary conditions. Both the emission data as well as the population density has been represented in the model system with the same high resolution. Previous health impact assessments related to air pollution have been made on a lower resolution. In this study, the integrated model system, EVA, has been used to estimate the health impacts and related external cost for Denmark at a 1 km x 1 km resolution. New developments of the integrated model system will be presented as well as the development of health impacts and related external costs in Europe and Denmark over a period of 36 years (1979-2014).

Using a set of appropriate air quality models and exposure-effect functions derived from the recent epidemiological literature, a methodological framework for risk assessment has been established and consistently applied across the different energy systems, including the analysis of consequences from a major nuclear accident. A wide range of health impacts resulting from increased air pollution and ionizing radiation is quantified, and the transferability of results derived from specific power plants to a more general context is discussed.

    Canada is a high-income country with a population of 33 million people. Its economic performance has been solid despite the recession that began in 2008. Life expectancy in Canada continues to rise and is high compared with most OECD countries; however, infant and maternal mortality rates tend to be worse than in countries such as Australia, France and Sweden. About 70% of total health expenditure comes from the general tax revenues of the federal, provincial and territorial governments. Most public revenues for health are used to provide universal medicare (medically necessary hospital and physician services that are free at the point of service for residents) and to subsidise the costs of outpatient prescription drugs and long-term care. Health care costs continue to grow at a faster rate than the economy and government revenue, largely driven by spending on prescription drugs. In the last five years, however, growth rates in pharmaceutical spending have been matched by hospital spending and overtaken by physician spending, mainly due to increased provider remuneration. The governance, organization and delivery of health services is highly decentralized, with the provinces and territories responsible for administering medicare and planning health services. In the last ten years there have been no major pan-Canadian health reform initiatives but individual provinces and territories have focused on reorganizing or fine tuning their regional health systems and improving the quality, timeliness and patient experience of primary, acute and chronic care. The medicare system has been effective in providing Canadians with financial protection against hospital and physician costs. However, the narrow scope of services covered under medicare has produced important gaps in coverage and equitable access may be a challenge in these areas. PMID:23628429

    Croatia is a small central European country on the Balkan peninsula, with a population of approximately 4.3 million and a gross domestic product (GDP) of 62% of the European Union (EU) average (expressed in purchasing power parity; PPP) in 2012. On 1 July 2013, Croatia became the 28th Member State of the EU. Life expectancy at birth has been increasing steadily in Croatia (with a small decline in the years following the 1991 to 1995 War of Independence) but is still lower than the EU average. Prevalence of overweight and obesity in the population has increased during recent years and trends in physical inactivity are alarming. The Croatian Health Insurance Fund (CHIF), established in 1993, is the sole insurer in the mandatory health insurance (MHI) system that provides universal health coverage to the whole population. The ownership of secondary health care facilities is distributed between the State and the counties. The financial position of public hospitals is weak and recent reforms were aimed at improving this. The introduction of concessions in 2009 (public private partnerships whereby county governments organize tenders for the provision of specific primary health care services) allowed the counties to play a more active role in the organization, coordination and management of primary health care; most primary care practices have been privatized. The proportion of GDP spent on health by the Croatian government remains relatively low compared to western Europe, as does the per capita health expenditure. Although the share of public expenditure as a proportion of total health expenditure (THE) has been decreasing, at around 82% it is still relatively high, even by European standards. The main source of the CHIFs revenue is compulsory health insurance contributions, accounting for 76% of the total revenues of the CHIF, although only about a third of the population (active workers) is liable to pay full health care contributions.

    Background Planning for the reliable and cost-effective supply of a health service commodity such as medical oxygen requires an understanding of the dynamic need or ‘demand’ for the commodity over time. In developing country health systems, however, collecting longitudinal clinical data for forecasting purposes is very difficult. Furthermore, approaches to estimating demand for supplies based on annual averages can underestimate demand some of the time by missing temporal variability. Methods A discrete event simulation model was developed to estimate variable demand for a health service commodity using the important example of medical oxygen for childhood pneumonia. The model is based on five key factors affecting oxygen demand: annual pneumonia admission rate, hypoxaemia prevalence, degree of seasonality, treatment duration, and oxygen flow rate. These parameters were varied over a wide range of values to generate simulation results for different settings. Total oxygen volume, peak patient load, and hours spent above average-based demand estimates were computed for both low and high seasons. Findings Oxygen demand estimates based on annual average values of demand factors can often severely underestimate actual demand. For scenarios with high hypoxaemia prevalence and degree of seasonality, demand can exceed average levels up to 68% of the time. Even for typical scenarios, demand may exceed three times the average level for several hours per day. Peak patient load is sensitive to hypoxaemia prevalence, whereas time spent at such peak loads is strongly influenced by degree of seasonality. Conclusion A theoretical study is presented whereby a simulation approach to estimating oxygen demand is used to better capture temporal variability compared to standard average-based approaches. This approach provides better grounds for health service planning, including decision-making around technologies for oxygen delivery. Beyond oxygen, this approach is widely

    Silver (Ag) is discharged in wastewater effluents and is also a component in a proposed secondary water disinfectant. A steady-state model was developed to simulate bioaccumulation in aquatic biota and assess ecological and human health risks. Trophic levels included phytoplankton, invertebrates, brown trout, and common carp. Uptake routes included water, food, or sediment. Based on an extensive review of the literature, distributions were derived for most inputs for use in Monte Carlo simulations. Three scenarios represented ranges of dilution and turbidity. Compared with the limited field data available, median estimates of Ag in carp (0.07-2.1 Iμg/g dry weight) were 0.5 to 9 times measured values, and all measurements were within the predicted interquartile range. Median Ag concentrations in biota were ranked invertebrates > phytoplankton > trout > carp. Biotic concentrations were highest for conditions of low dilution and low turbidity. Critical variables included Ag assimilation eficiency, specific feeding rate, and the phytoplankton bioconcentration factor. Bioaccumulation of Ag seems unlikely to result in txicity to aquatic biota and humans consuming fish. Although the highest predicted Ag concentrations in water (>200 ng/L) may pose chronic risks to early survival and development of salmonids and risks of argyria to subsistence fishers, these results occur under highly conservative conditions.

The need to consolidate the theoretical background which supports the advances already achieved in order to understand recent events in the area is stressed. In this regard, the health reform is understood as a question transcending the mere administrative and managerial aspect of the health system, since it necessarily involves a redefinition of the concepts of health, disease and the medical practice adopted by the dominant mechanistic paradigm of medicine. The recent events which delineate the health system in Brazil are analysed and criticised in the light of this concern. PMID:1307428

    The recent history of Costa Rica's health system is reviewed, emphasizing the health-related effects of the economic crisis of the 1980s. This economic crisis has stopped and in some instances reversed the marked health improvements Costa Rica realized during the decade of the 1970s. The effects of the economic crisis emerge in 4 areas: deterioration in health status, as poverty contributed to higher disease rates; reductions in the government's ability to maintain public health and medical services; increased reliance on foreign aid to finance the health system; and growing national debate over the role of the state in health care. The result of the economic crisis was a reduction in health services and a questioning of the Costa Rican health model. This occurred following the implementation of an expensive health infrastructure and at a time when people most needed health services. During the 1941-70 period, domestic initiative can account for much of the expansion of Costa Rica's social security system, but also at this time international agencies such as the US Agency for International Development (USAID) and the Inter-American Development began to assist in the expansion of the health system. In 1971 a plan was initiated to create a nationalized health system. By 1980 the success of the health sector reorganization was evident in the statistics: marked improvements in life expectancy, infant mortality, and infectious disease mortality had surpassed the goals set by the Pan American Health Organization (PAHO) and the Ministry of Health. Costa Rica's success was a vindication of both policy goals and funding priorities, for it has been "proved" that primary health care was capable of improving health indices, particularly where the agencies had the active and conscientious support of the national government. By 1977, foreign contracts for aid had expired, and the Ministry declared that the rural health program would be supported totally by the government. The

    OBJECTIVES: Interorganizational collaboration aimed at community health improvement is an expectation of local public health systems. This study assessed the extent to which such collaboration occurred within one state (Wisconsin), described the characteristics of existing partnerships, and identified factors associated with partnership effectiveness. METHODS: In Stage 1, local health department (LHD) directors in Wisconsin were surveyed (93% response rate). In Stage 2, LHDs completed self-administered mailed surveys for each partnership identified in Stage 1 (85% response rate). Two-level hierarchical logit regression methods were used to model relationships between partnership and LHD variables and partnership outcomes. Data from 924 partnerships associated with 74 LHDs were included in the analysis. RESULTS: Partnerships most frequently addressed tobacco prevention and control, maternal and child health, emergency planning, community assessment and planning, and immunizations. Partnering was most frequent with other government agencies, hospitals, medical practices or clinics, community-based organizations, and schools. Partnership effectiveness was predicted by having a budget, having more partners contributing financially, having a broader array of organizations involved, and having been in existence for a longer period of time. A government mandate to start the partnership was inversely related to successful outcomes. Characteristics of LHDs did not predict partnership effectiveness. CONCLUSIONS: Financial support, having a broader array of partners, and allowing sufficient time for partnerships to succeed contribute to partnership effectiveness. Further study-using objective outcome measures-is needed to examine the effects of organizational and community characteristics on the effectiveness of local public health system partnerships.

  18. Primary health care and public health: foundations of universal health systems.

    PubMed

    White, Franklin

    2015-01-01

    The aim of this review is to advocate for more integrated and universally accessible health systems, built on a foundation of primary health care and public health. The perspective outlined identified health systems as the frame of reference, clarified terminology and examined complementary perspectives on health. It explored the prospects for universal and integrated health systems from a global perspective, the role of healthy public policy in achieving population health and the value of the social-ecological model in guiding how best to align the components of an integrated health service. The importance of an ethical private sector in partnership with the public sector is recognized. Most health systems around the world, still heavily focused on illness, are doing relatively little to optimize health and minimize illness burdens, especially for vulnerable groups. This failure to improve the underlying conditions for health is compounded by insufficient allocation of resources to address priority needs with equity (universality, accessibility and affordability). Finally, public health and primary health care are the cornerstones of sustainable health systems, and this should be reflected in the health policies and professional education systems of all nations wishing to achieve a health system that is effective, equitable, efficient and affordable.

    The United States has set a national goal to eliminate health disparities. This article emphasizes the importance of food systems in generating and exacerbating health disparities in the United States and suggests avenues for reducing them. It presents a conceptual model showing how broad food system conditions interplay with community food environments—and how these relationships are filtered and refracted through prisms of social disparities to generate and exacerbate health disparities. Interactions with demand factors in the social environment are described. The article also highlights the separate food systems pathway to health disparities via environmental and occupational health effects of agriculture. PMID:23173027

    This paper describes and analyses six models of health and disease. These are: religious, biomedical, psychosomatic, humanistic, existential and transpersonal. Of these six models, only one was unequivocally reductionist: the biomedical. The others were all holistic. The religious, humanistic and transpersonal models could be considered as health models, the biomedical, psychosomatic and existential models as disease or illness models. The different models were assumed to depict different, but related, ways of representing health and disease. It is probable that different groups in society, including the different groups in the health service--doctors, nurses and patients--look at health and illness from partly different models. This is considered to have significant implications for the health service. PMID:8217913

    The paper proposes the diagnostic and prognostic modeling and test validation of a Wireless Integrated Strain Monitoring and Simulation System (WISMOS). The effort verifies a hardware and web based software tool that is able to evaluate and optimize sensorized aerospace composite structures for the purpose of Structural Health Monitoring (SHM). The tool is an extension of an existing suite of an SHM system, based on a diagnostic-prognostic system (DPS) methodology. The goal of the extended SHM-DPS is to apply multi-scale nonlinear physics-based Progressive Failure analyses to the "as-is" structural configuration to determine residual strength, remaining service life, and future inspection intervals and maintenance procedures. The DPS solution meets the JTI Green Regional Aircraft (GRA) goals towards low weight, durable and reliable commercial aircraft. It will take advantage of the currently developed methodologies within the European Clean sky JTI project WISMOS, with the capability to transmit, store and process strain data from a network of wireless sensors (e.g. strain gages, FBGA) and utilize a DPS-based methodology, based on multi scale progressive failure analysis (MS-PFA), to determine structural health and to advice with respect to condition based inspection and maintenance. As part of the validation of the Diagnostic and prognostic system, Carbon/Epoxy ASTM coupons were fabricated and tested to extract the mechanical properties. Subsequently two composite stiffened panels were manufactured, instrumented and tested under compressive loading: 1) an undamaged stiffened buckling panel; and 2) a damaged stiffened buckling panel including an initial diamond cut. Next numerical Finite element models of the two panels were developed and analyzed under test conditions using Multi-Scale Progressive Failure Analysis (an extension of FEM) to evaluate the damage/fracture evolution process, as well as the identification of contributing failure modes.

    Complex systems abound in public health. Complex systems are made up of heterogeneous elements that interact with one another, have emergent properties that are not explained by understanding the individual elements of the system, persist over time and adapt to changing circumstances. Public health is starting to use results from systems science studies to shape practice and policy, for example in preparing for global pandemics. However, systems science study designs and analytic methods remain underutilized and are not widely featured in public health curricula or training. In this review we present an argument for the utility of systems science methods in public health, introduce three important systems science methods (system dynamics, network analysis, and agent-based modeling), and provide three case studies where these methods have been used to answer important public health science questions in the areas of infectious disease, tobacco control, and obesity.

    The influence of individual-level factors such as pretraumatic risk and protective factors and the availability of unit-level and enterprise-level factors on psychological health outcomes have been previously considered individually, but have not been considered in tandem across the U.S. Military psychological health system. We use the existing literature on military psychological health to build a conceptual system dynamics model of the U.S. Military psychological health system "service-cycle" from accession and deployment to future psychological health screening and treatment. The model highlights a few key observations, challenges, and opportunities for improvement for the system that relate to several topics including the importance of modeling operational demand combined with the population's psychological health as opposed to only physical health; the role of resilience and post-traumatic growth on the mitigation of stress; the positive and negative effects of pretraumatic risk factors, unit support, and unit leadership on the service-cycle; and the opportunity to improve the system more rapidly by including more feedback mechanisms regarding the usefulness of pre- and post-traumatic innovations to medical leaders, funding authorities, and policy makers.

Part two is devoted to the description of the basic structure of the system: its main institutions, the population coverage, the health benefits of those affiliated to the different heath institutions, its financial sources, the levels of financial protection in health, the availability of physical, material and human resources for health, and the stewardship functions displayed by the Ministry of Health and other actors. This part also discusses the role of citizens in the monitorization and evaluation of the health system, as well as the levels of satisfaction with the rendered health services. In part three the most recent innovations and its impact on the performance of the health system are discussed. Salient among them are the System of Social Protection in Health and the Popular Health Insurance.

    Background Early diagnosis combined with an early intervention program, such as the Early Start Denver Model (ESDM), can positively influence the early natural history of autism spectrum disorders. This study evaluated the effectiveness of an early ESDM-inspired intervention, in a small group of toddlers, delivered at low intensity by the Italian Public Health System. Methods Twenty-one toddlers at risk for autism spectrum disorders, aged 20–36 months, received 3 hours/wk of one-to-one ESDM-inspired intervention by trained therapists, combined with parents’ and teachers’ active engagement in ecological implementation of treatment. The mean duration of treatment was 15 months. Cognitive and communication skills, as well as severity of autism symptoms, were assessed by using standardized measures at pre-intervention (Time 0 [T0]; mean age =27 months) and post-intervention (Time 1 [T1]; mean age =42 months). Results Children made statistically significant improvements in the language and cognitive domains, as demonstrated by a series of nonparametric Wilcoxon tests for paired data. Regarding severity of autism symptoms, younger age at diagnosis was positively associated with greater improvement at post-assessment. Conclusion Our results are consistent with the literature that underlines the importance of early diagnosis and early intervention, since prompt diagnosis can reduce the severity of autism symptoms and improve cognitive and language skills in younger children. Particularly in toddlers, it seems that an intervention model based on the ESDM principles, involving the active engagement of parents and nursery school teachers, may be effective even when the individual treatment is delivered at low intensity. Furthermore, our study supports the adaptation and the positive impact of the ESDM entirely sustained by the Italian Public Health System. PMID:27366069

    Mexico is undergoing profound health reform, extending health insurance to previously uninsured populations and changing the way health care services are delivered. Legislation enacted in 2003 and implemented in 2004 mandated funding and infrastructure that will allow 52% of Mexico's population to access medical care at no cost by 2010. This ambitious social reform has not been without challenges, particularly financial sustainability. Health promotion, because of its potential to prevent or delay chronic diseases and injuries and their associated costs, is a key component of health care reform. In 2006, the Ministry of Health's General Directorate of Health Promotion developed the Health Promotion Operational Model. Based on Ottawa Charter functions, the model integrates health promotion activities within the overall health care system. The main goal of this model is to build strong human capital and to improve organizational capacity for health promotion starting at the local level by training health care personnel to implement health promotion activities. Organizational development workshops started in 2006, and implementation plans in all 32 Mexican states were in place by end of 2008. PMID:19080038

    Public health and healthcare originally started out separately from one another in the past, having later further developed taking different paths in modern times. The major development the health systems underwent in the last half of the 20th century entailed a heightening of the individual standpoint and a division of these two approaches despite the attempts made to bring them together as of the WHO Alma-Ata Conference in 1978. The waning of rationalism and other social phenomena had a hand the collective or population-oriented focus being focused on to a lesser degree in Public Health, but these trends also gave rise to a growing problem of rationality in individual healthcare and sustainability in the public health systems. The debate on the current scene stands to set out the sustainability-related problems mediated by internal and external agents and to revise Public Health's possible contribution to the improvement thereof by advocating yet a further attempt at bringing together and integrating these two diverging standpoints.

    BACKGROUND People who are deaf use health care services differently than the general population; little research has been carried out to understand the reasons. OBJECTIVE To better understand the health care experiences of deaf people who communicate in American Sign Language. DESIGN Qualitative analyses of focus group discussions in 3 U.S. cities. PARTICIPANTS Ninety-one deaf adults who communicate primarily in American Sign Language. MEASUREMENTS We collected information about health care communication and perceptions of clinicians' attitudes. We elicited stories of both positive and negative encounters, as well as recommendations for improving health care. RESULTS Communication difficulties were ubiquitous. Fear, mistrust, and frustration were prominent in participants' descriptions of health care encounters. Positive experiences were characterized by the presence of medically experienced certified interpreters, health care practitioners with sign language skills, and practitioners who made an effort to improve communication. Many participants acknowledged limited knowledge of their legal rights and did not advocate for themselves. Some participants believed that health care practitioners should learn more about sociocultural aspects of deafness. CONCLUSIONS Deaf people report difficulties using health care services. Physicians can facilitate change to improve this. Future research should explore the perspective of clinicians when working with deaf people, ways to improve communication, and the impact of programs that teach deaf people self-advocacy skills and about their legal rights.

    The Integrated Medical Model (IMM) is a decision support tool used by medical system planners and designers as they prepare for exploration planning activities of the Constellation program (CxP). IMM provides an evidence-based approach to help optimize the allocation of in-flight medical resources for a specified level of risk within spacecraft operational constraints. Eighty medical conditions and associated resources are represented in IMM. Nine conditions are due to Space Adaptation Syndrome. The IMM helps answer fundamental medical mission planning questions such as What medical conditions can be expected? What type and quantity of medical resources are most likely to be used?", and "What is the probability of crew death or evacuation due to medical events?" For a specified mission and crew profile, the IMM effectively characterizes the sequence of events that could potentially occur should a medical condition happen. The mathematical relationships among mission and crew attributes, medical conditions and incidence data, in-flight medical resources, potential clinical and crew health end states are established to generate end state probabilities. A Monte Carlo computational method is used to determine the probable outcomes and requires up to 25,000 mission trials to reach convergence. For each mission trial, the pharmaceuticals and supplies required to diagnose and treat prevalent medical conditions are tracked and decremented. The uncertainty of patient response to treatment is bounded via a best-case, worst-case, untreated case algorithm. A Crew Health Index (CHI) metric, developed to account for functional impairment due to a medical condition, provides a quantified measure of risk and enables risk comparisons across mission scenarios. The use of historical in-flight medical data, terrestrial surrogate data as appropriate, and space medicine subject matter expertise has enabled the development of a probabilistic, stochastic decision support tool capable of

    Introduction: Although there are several models of integrated architecture, we still lack models and theories about the integration process of health system responses to HIV/AIDS and NCDs. Objective: The overall purpose of this study is to design an action model, a systematic approach, for the integration of health system responses to HIV/AIDS and NCDs in developing countries. Methods: An iterative and progressive approach of model development using inductive qualitative evidence synthesis techniques was applied. As evidence about integration is spread across different fields, synthesis of evidence from a broad range of disciplines was conducted. Results: An action model of integration having 5 underlying principles, 4 action fields, and a 9-step action cycle is developed. The INTEGRATE model is an acronym of the 9 steps of the integration process: 1) Interrelate the magnitude and distribution of the problems, 2) Navigate the linkage between the problems, 3) Testify individual level co-occurrence of the problems, 4) Examine the similarities and understand the differences between the response functions, 5) Glance over the health system’s environment for integration, 6) Repackage and share evidence in a useable form, 7) Ascertain the plan for integration, 8) Translate the plan in to action, 9) Evaluate and Monitor the integration. Conclusion: Our model provides a basis for integration of health system responses to HIV/AIDS and NCDs in the context of developing countries. We propose that future empirical work is needed to refine the validity and applicability of the model. PMID:24373260

    This analysis of the Czech health system reviews recent developments in organization and governance, health financing, health-care provision, health reforms and health system performance. The Czech health-care system is based on compulsory statutory health insurance providing virtually universal coverage and a broad range of benefits, and doing so at 7.7 % of GDP in 2012 - well below the EU average - of which a comparatively high 85 % was publicly funded. Some important health indicators are better than the EU averages (such as mortality due to respiratory disease) or even among the best in the world (in terms of infant mortality, for example). On the other hand, mortality rates for diseases of the circulatory system and malignant neoplasms are well above the EU average, as are a range of health-care utilization rates, such as outpatient contacts and average length of stay in acute care hospitals. In short, there is substantial potential in the Czech Republic for efficiency gains and to improve health outcomes. Furthermore, the need for reform in order to financially sustain the system became evident again after the global financial crisis, but there is as yet no consensus about how to achieve this.

    Informatization process of the Croatian health care system started relatively early. Computer processing of data of persons not covered by health insurance started in 1968 in Zagreb. Remetinec Health Center served as a model of computer data processing (CDP) in primary health care and Sveti Duh General Hospital in inpatient CDP, whereas hospital administration and health service were first introduced to Zagreb University Hospital Center and Sestre Milosrdnice University Hospital. At Varazdin Medical Center CDP for health care services started in 1970. Several registries of chronic diseases have been established: cancer, psychosis, alcoholism, and hospital registries as well as pilot registries of lung tuberculosis patients and diabetics. Health statistics reports on healthcare services, work accidents and sick-leaves as well as on hospital mortality started to be produced by CDP in 1977. Besides alphanumeric data, the modern information technology (IT) can give digital images and signals. Communication in health care system demands a standardized format of all information, especially for telemedicine. In 2000, Technical Committee for Standardization in Medical Informatics was founded in Croatia, in order to monitor the activities of the International Standardization Organization (ISO) and Comite Européen de Normalisation (CEN), and to implement their international standards in the Croatian standardization procedure. The HL7 Croatia has also been founded to monitor developments in the communication standard HL7. So far, the Republic of Croatia has a number of acts regulating informatization in general and consequently the informatization of the health care system (Act on Personal Data Confidentiality, Act on Digital Signature, Act of Standardization) enacted. The ethical aspect of data security and data protection has been covered by the Code of Ethics for medical informaticians.

    Abstract International collaborative health research is justifiably expected to help reduce global health inequities. Investment in health policy and systems research in developing countries is essential to this process but, currently, funding for international research is mainly channelled towards the development of new medical interventions. This imbalance is largely due to research legislation and policies used in high-income countries. These policies have increasingly led these countries to invest in health research aimed at boosting national economic competitiveness rather than reducing health inequities. In the United States of America and the United Kingdom of Great Britain and Northern Ireland, the regulation of research has encouraged a model that: leads to products that can be commercialized; targets health needs that can be met by profitable, high-technology products; has the licensing of new products as its endpoint; and does not entail significant research capacity strengthening in other countries. Accordingly, investment in international research is directed towards pharmaceutical trials and product development public–private partnerships for neglected diseases. This diverts funding away from research that is needed to implement existing interventions and to strengthen health systems, i.e. health policy and systems research. Governments must restructure their research laws and policies to increase this essential research in developing countries. PMID:22271965

    Background Mortality rates amongst ST segment elevation myocardial infarction (STEMI) patients remain high, especially in developing countries. The aim of this study was to evaluate the factors related with delays in the treatment of STEMI patients to support a strategic plan toward structural and personnel modifications in a primary hospital aligning its process with international guidelines. Methods and Findings The study was conducted in a primary hospital localized in Foz do Iguaçu, Brazil. We utilized a qualitative and quantitative integrated analysis including on-site observations, interviews, medical records analysis, Qualitative Comparative Analysis (QCA) and System Dynamics Modeling (SD). Main cause of delays were categorized into three themes: a) professional, b) equipment and c) transportation logistics. QCA analysis confirmed four main stages of delay to STEMI patient’s care in relation to the ‘Door-in-Door-out’ time at the primary hospital. These stages and their average delays in minutes were: a) First Medical Contact (From Door-In to the first contact with the nurse and/or physician): 7 minutes; b) Electrocardiogram acquisition and review by a physician: 28 minutes; c) ECG transmission and Percutaneous Coronary Intervention Center team feedback time: 76 minutes; and d) Patient’s Transfer Waiting Time: 78 minutes. SD baseline model confirmed the system’s behavior with all occurring delays and the need of improvements. Moreover, after model validation and sensitivity analysis, results suggested that an overall improvement of 40% to 50% in each of these identified stages would reduce the delay. Conclusions This evaluation suggests that investment in health personnel training, diminution of bureaucracy, and management of guidelines might lead to important improvements decreasing the delay of STEMI patients’ care. In addition, this work provides evidence that SD modeling may highlight areas where health system managers can implement and

    The increasing concern and interest in the health delivery system in the United States has placed the health system planners in a difficult position. They are inadequately prepared, in many cases, to deal with the management techniques that have been designed for use with system problems. This situation has been compounded by the failure, until recently, of educational programs to train new health professionals in these techniques. Computer simulation is a technique that allows the planners dynamic feedback on his proposed plans. This same technique provides the planning student with a better understanding of the systems planning process. PMID:1115292

    International health is still highly dominated by equilibrium approaches. The emergence of systems thinking in international health provides a great avenue to develop innovative health interventions adapted to changing contexts. The public health community, nevertheless, has the responsibility to translate concepts related to systems thinking and complexity into concrete research methods and interventions. One possibility is to consider the properties of systems such as resilience and adaptability as entry points to better understand how health systems react to shocks. PMID:25905481

    PubMed

    Guidotti, Tee L

    2013-01-01

    Communication models common in environmental health are not well represented in the literature on health communication. Risk communication is a systematic approach to conveying essential information about a specific environmental issue and a framework for thinking about community risk and the alternatives for dealing with it. Crisis communication is intended to provide essential information to people facing an emergency in order to mitigate its effects and to enable them to make appropriate decisions, and it is primarily used in emergency management. Corporate communication is intended to achieve a change in attitude or perception of an organization, and its role in environmental health is usually public relations or to rehabilitate a damaged reputation. Environmental health education is a more didactic approach to science education with respect to health and the environment. Social marketing uses conventional marketing methods to achieve a socially desirable purpose but is more heavily used in health promotion generally. Communication models and styles in environmental health are specialized to serve the needs of the field in communicating with the community. They are highly structured and executed in different ways but have in common a relative lack of emphasis on changing personal or lifestyle behavior compared with health promotion and public health in general and a tendency to emphasize content on specific environmental issues and decision frameworks for protecting oneself or the community through collective action.

    The Health Systems in Transition (HiT) profiles are country-based reports that provide a detailed description of health systems and of policy initiatives in progress or under development. HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems. They also describe the institutional framework, process, content, and implementation of health and health care policies, highlighting challenges and areas that require more in-depth analysis. Undoubtedly the dominant issue in the Dutch health care system at present is the fundamental reform that came into effect in 2006. With the introduction of a single compulsory health insurance scheme, the dual system of public and private insurance for curative care became history. Managed competition for providers and insurers became a major driver in the health care system. This has meant fundamental changes in the roles of patients, insurers, providers and the government. Insurers now negotiate with providers on price and quality and patients choose the provider they prefer and join a health insurance policy which best fits their situation. To allow patients to make these choices, much effort has been made to make information on price and quality available to the public. The role of the national government has changed from directly steering the system to safeguarding the proper functioning of the health markets. With the introduction of market mechanisms in the health care sector and the privatization of former sickness funds, the Dutch system presents an innovative and unique variant of a social health insurance system. Since the stepwise realization of the blueprint of the system has not yet been completed, the health care system in The Netherlands should be characterized as being in transition. Many measures have been taken to move from the old to the new system as smoothly as possible. Financial measures intended to prevent sudden budgetary

    Abstract Background: This study was performed to evaluate the safety and efficacy of a fully automated artificial pancreas using zone-model predictive control (zone-MPC) with the health monitoring system (HMS) during unannounced meals and overnight and exercise periods. Subjects and Methods: A fully automated closed-loop artificial pancreas was evaluated in 12 subjects (eight women, four men) with type 1 diabetes (mean±SD age, 49.4±10.4 years; diabetes duration, 32.7±16.0 years; glycosylated hemoglobin, 7.3±1.2%). The zone-MPC controller used an a priori model that was initialized using the subject's total daily insulin. The controller was designed to keep glucose levels between 80 and 140 mg/dL. A hypoglycemia prediction algorithm, a module of the HMS, was used in conjunction with the zone controller to alert the user to consume carbohydrates if the glucose level was predicted to fall below 70 mg/dL in the next 15 min. Results: The average time spent in the 70–180 mg/dL range, measured by the YSI glucose and lactate analyzer (Yellow Springs Instruments, Yellow Springs, OH), was 80% for the entire session, 92% overnight from 12 a.m. to 7 a.m., and 69% and 61% for the 5-h period after dinner and breakfast, respectively. The time spent <60 mg/dL for the entire session by YSI was 0%, with no safety events. The HMS sent appropriate warnings to prevent hypoglycemia via short and multimedia message services, at an average of 3.8 treatments per subject. Conclusions: The combination of the zone-MPC controller and the HMS hypoglycemia prevention algorithm was able to safely regulate glucose in a tight range with no adverse events despite the challenges of unannounced meals and moderate exercise.

    Introduction Although the regionalization of public health systems has been well documented in the case of emergency preparedness, there is little literature on the application of regional approaches to other aspects of public health. From 2011 through 2014 the Washington State Department of Health implemented a Community Transformation Grant to support community-level policy and systems changes to decrease chronic disease risk factors and increase access to clinical preventive services. The Department of Health implemented the grant through a regional model, grouping 32 of the state’s 35 local health jurisdictions into 5 regions. Our process evaluation identifies the challenges and facilitators to Community Transformation Grant planning and implementation. Methods We conducted 34 key informant interviews with people directly involved in the implementation of the Community Transformation Grant. We interviewed state and local partners, including representatives from each region, the Department of Health, external consultants, and regional partners. We collected data from October 2013 through July 2014. Results Challenges for planning, building, and implementing a regional model for chronic disease prevention included stakeholder buy-in, regional geography, and communication; facilitators included shared regional history and infrastructure, strong leadership, collaborative relationships, shared vision and goals, sufficient funding, and direct technical assistance and training. Conclusion Lessons learned in Washington State provide a foundation for other states interested in using a regional approach to reduce chronic disease risk. Policy and systems changes require adequate time, funding, and staffing. States and funders should work closely with local leaders to address these challenges and facilitators. PMID:25789498

    In order to construct a function model of community health service (CHS) information for development of CHS information management system, Integration Definition for Function Modeling (IDEF0), an IEEE standard which is extended from Structured Analysis and Design(SADT) and now is a widely used function modeling method, was used to classifying its information from top to bottom. The contents of every level of the model were described and coded. Then function model for CHS information, which includes 4 super-classes, 15 classes and 28 sub-classed of business function, 43 business processes and 168 business activities, was established. This model can facilitate information management system development and workflow refinement.

    This paper describes the Venezuelan health system, including its structure and coverage, financial sources, human and material resources and its stewardship functions. This system comprises a public and a private sector. The public sector includes the Ministry of Popular Power for Health (MS) and several social security institutions, salient among them the Venezuelan Institute for Social Security (IVSS). The MH is financed with federal, state and county contributions. The IVSS is financed with employer, employee and government contributions. These two agencies provide services in their own facilities. The private sector includes providers offering services on an out-of-pocket basis and private insurance companies. The Venezuelan health system is undergoing a process of reform since the adoption of the 1999 Constitution which calls for the establishment of a national public health system. The reform process is now headed by the Barrio Adentro program. PMID:21877092

    The Bremen model recognizes that refugee health care has to go beyond merely checking for the prevalence of contagious diseases. Elementary health care offered in the reception centre and transitory facilities is based on voluntary acceptance by the refugees. At the same time, legal requirements for the medical reception of refugees are observed. In addition, doctors performing the initial medical examination are enabled to cover acute care on the spot. During the preliminary phase of immigration refugees are allowed to see a doctor in their facility repeatedly. After a certain time, they are provided with a health card permitting limited access to regular care outside of their facility. The current rise of refugee numbers affects the situation of Bremen health care for adult as well as juvenile refugees. In spite of the increase, health care standards are maintained by means of the health card. From 2011 to 2014, "Factors influencing health status and contact with health services" averaged 29.6 % in the health check data. Diseases of the respiratory system (18.1 %) and "symptoms, signs and abnormal findings not elsewhere classified" (16.9 %) ranked second and third, respectively. Diseases of the digestive system (6.1 %) of the musculoskeletal system (6 %) and of the skin and subcutaneous tissue (3.6 %) followed. Infectious diseases such as HIV infections, hepatitis or tuberculosis were seldom. PMID:27098974

    Objective To design, build, implement, and evaluate a personal health record (PHR), tethered to the Military Health System, that leverages Microsoft® HealthVault and Google® Health infrastructure based on user preference. Materials and methods A pilot project was conducted in 2008–2009 at Madigan Army Medical Center in Tacoma, Washington. Our PHR was architected to a flexible platform that incorporated standards-based models of Continuity of Document and Continuity of Care Record to map Department of Defense-sourced health data, via a secure Veterans Administration data broker, to Microsoft® HealthVault and Google® Health based on user preference. The project design and implementation were guided by provider and patient advisory panels with formal user evaluation. Results The pilot project included 250 beneficiary users. Approximately 73.2% of users were <65 years of age, and 38.4% were female. Of the users, 169 (67.6%) selected Microsoft® HealthVault, and 81 (32.4%) selected Google® Health as their PHR of preference. Sample evaluation of users reflected 100% (n=60) satisfied with convenience of record access and 91.7% (n=55) satisfied with overall functionality of PHR. Discussion Key lessons learned related to data-transfer decisions (push vs pull), purposeful delays in reporting sensitive information, understanding and mapping PHR use and clinical workflow, and decisions on information patients may choose to share with their provider. Conclusion Currently PHRs are being viewed as empowering tools for patient activation. Design and implementation issues (eg, technical, organizational, information security) are substantial and must be thoughtfully approached. Adopting standards into design can enhance the national goal of portability and interoperability. PMID:21292705

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

    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

    The road towards political freedom has been painful to the Hungarian population. After 1989, the per capita GDP has sharply decreased, and the 1989 level has been reached again only a decade later. During the period, a great number of reforms have been launched in the health field: privatisation, adoption of a Bismarckian-like model, decentralization, performance-search measures... One cannot say however that these reforms have been successful. Low priority for health, vastage of the scarce resources allocated to the health care system, conflicts for power between the groups and institutions ... have seriously weakened the performance of all the system. Simultaneously, the financial burden charged to the patients has increased and the unhealthy lifestyle of the population has not decreased. In its 2000 Report on the world health, WHO has noted that Hungary is ranked 36th for per capita GDP, 59th for per capita health expenditures but 105th for the performance of its health care system.

    Dental hygienists help their clients develop health promoting behaviors, by providing essential information about general health, and oral health in particular. Individual health practices such as oral self-care are based on personal choices. The guiding principles found in health behavior models provide useful methods to the oral health care providers in promoting effective individual client behaviors. Theories provide explanations about observable facts in a systematic manner. Research regarding health behavior has explored the effectiveness and applicability of various health models in oral health behavior modification. The Health Belief Model, Transtheoretical Model and Stages of Change, Theory of Reasoned Action, Self-Efficacy, Locus of Control, and Sense of Coherence are examples of models that focus on individuals assuming responsibility for their own health. Understanding the strengths of each and their applicability to health behaviors is critical for oral health care providers who work with patients to adopt methods and modify behaviors that contribute to good oral health. This paper describes health behavior models that have been applied to oral health education, presents a critical analysis of the effectiveness of each model in oral health education, and provides examples of application to oral health education.

    The implementation of an integrated system health management (ISHM) capability is fundamentally linked to the management of data, information, and knowledge (DIaK) with the purposeful objective of determining the health of a system. It is akin to having a team of experts who are all individually and collectively observing and analyzing a complex system, and communicating effectively with each other in order to arrive at an accurate and reliable assessment of its health. In this paper, concepts, procedures, and approaches are presented as a foundation for implementing an intelligent systems ]relevant ISHM capability. The capability stresses integration of DIaK from all elements of a system. Both ground-based (remote) and on-board ISHM capabilities are compared and contrasted. The information presented is the result of many years of research, development, and maturation of technologies, and of prototype implementations in operational systems.

    Information production and its communication being a key public health activity, developing modern information systems is a precondition for its fulfilling these assignments. A national public health information system (NPHIS) is a set of human resources combined with computing and communication technologies. It enables data linkage and data coverage as well as undertaking information production and dissemination in an effective, standardized and safe way. The Croatian Institute of Public Health LAN/WAN modules are under development. Health Safety System, Health Workers Registry, and Digital Library are among the Institute's developmental priorities. Communication between NPHIS participants would unfold over the Internet by using every relevant data protection method. Web technology-based applications would be run on special servers. Between individual applications, use would be made of the transaction module of communication through an exchange of the HL7 standard-based xml messages. In the conditions of transition, the health system must make an optimal use of the resources, which is not feasible without applying modern information and communication technologies. PMID:16095199

    This paper describes the Chilean health system, including its structure, financing, beneficiaries, and its physical, material and human resources. This system has two sectors, public and private. The public sector comprises all the organisms that constitute the National System of Health Services, which covers 70% of the population, including the rural and urban poor, the low middle-class, the retired, and the self-employed professionals and technicians.The private sector covers 17.5% of the population, mostly the upper middle-class and the high-income population. A small proportion of the population uses private health services and pays for them out-of-pocket. Around l0% of the population is covered by other public agencies, basically the Health Services for the Armed Forces. The system was recently reformed with the establishment of a Universal System of Explicit Entitlements, which operates through a Universal Plan of Explicit Entitlements (AUGE), which guarantees timely access to treatment for 56 health problems, including cancer in children, breast cancer, ischaemic heart disease, HIV/AIDS and diabetes.

    This article recounts the development of a model for social capital building developed over the course of interventions focused on HIV-related stigma and discrimination, safe motherhood and reproductive health. Through further engagement with relevant literature, it explores the nature of social capital and suggests why undertaking such a process can enhance health policy and programmes, advocacy and governance for improved health systems strengthening (HSS) outcomes. The social capital process proposed facilitates the systematic and effective inclusion of community voices in the health policy process-strengthening programme effectiveness as well as health system accountability and governance. Because social capital building facilitates communication and the uptake of new ideas, norms and standards within and between professional communities of practice, it can provide an important mechanism for integration both within and between sectors-a process long considered a 'wicked problem' for health policy-makers. The article argues that the systematic application of social capital building, from bonding through bridging into linking social capital, can greatly enhance the ability of governments and their partners to achieve their HSS goals.

    PubMed

    Labonté, Ronald

    2010-01-01

    This article addresses several issues pertinent to health systems governance for health equity. It argues the importance of health systems using measures of positive health (well-being), discriminating in favour of historically less advantaged groups and weighing the costs of health care against investments in the social determinants of health. It cautions that the concept of governance could weaken the role of government, with disequalizing effects, while emphasizing the importance of two elements of good governance (transparency and participation) in health systems decision-making. It distinguishes between participation as volunteer labour and participation as exercising political rights, and questions the assumption that decentralization in health systems is necessarily empowering. It then identifies five health system roles to address issues of equity (educator/watchdog, resource broker, community developer, partnership developer and advocate/catalyst) and the implications of these roles for practice. Drawing on preliminary findings of a global research project on comprehensive primary health care, it discusses political aspects of progressive health system reform and the implications of equity-focused health system governance on health workers' roles, noting the importance of health workers claiming their identity as citizens. The article concludes with a commentary on the inherently political nature of health reforms based on equity; the necessary confrontation with power relations politics involves; and the health systems governance challenge of managing competing health discourses of efficiency and results-based financing, on the one hand, and equity and citizen empowerment, on the other.

    Analysis of the relationship between public health and the health system requires definition of a conceptual framework and the choice of a particular context. The chosen context of this discussion is the management of public organizations. With this in mind, functions will be associated with organizational macroprocesses. From this point of view, this article identifies the functions-processes that any health system should develop and their goals. The current situation of public health in the health system is analyzed through the study of public health budgets and the place they occupy in the hierarchy of the health departments of the autonomous communities. The "public health" budget program represents an average of 1.34% of health expenditure in the autonomous communities in 2010. Over 20% of public health organizations of the autonomous communities have a rank lower than general directorate. These data indicate the low weight assigned to public health in the health systems of the Spanish state. To change this situation, consensus must be reached on the desired relationship between public health and the health system. Such a consensus would then have to be accepted and work would have to be undertaken to improve results. Three alternatives are proposed: (i) public health would be an organization that would be above or outside the health system; (ii) public health would be synonymous with the public health system; and (iii) public health would form part of the health system with a range of assigned functions. Finally, we provide some recommendations to help define the most effective and efficient relationship between public health and the health system. PMID:20970219

    To estimate additional total cost and average cost of integrating the demand-based reproductive health commodity model into the existing Government and NGO facilities in Bangladesh. Activity based cost analysis was conducted during 2006-2008 in two low performing rural sub-districts (Nabigong and Raipur sub-district) and one urban slum area in Dhaka city, Bangladesh. Activity-based cost data were collected using ingredient approach, which comprised of listing all types of inputs by activity, quantities and prices for each input. Total cost was presented according to capital and recurrent items. The supply side perspective was considered for entire analysis. The total cost of integrating demand-based reproductive health commodity (DBRHC) model into the Government and NGO service delivery system was estimated to BDT 18,667,634 (US$274,524). The proportion of capital cost was 59 % and the recurrent cost was 41 % of the total cost. The average cost per beneficiaries was BDT 230 (US$3.38) only for introducing this model into the existing health system. The built-in interventions of DBRHC model were doable at low-cost at the selected Government and NGO settings at the grass-root level. The model has potential of further cost containment during scaling up-if the intervention costs are adjusted with the existing functionaries of the Government and NGOs. PMID:26722628

    A document discusses the Portable Health Algorithms Test (PHALT) System, which has been designed as a means for evolving the maturity and credibility of algorithms developed to assess the health of aerospace systems. Comprising an integrated hardware-software environment, the PHALT system allows systems health management algorithms to be developed in a graphical programming environment, to be tested and refined using system simulation or test data playback, and to be evaluated in a real-time hardware-in-the-loop mode with a live test article. The integrated hardware and software development environment provides a seamless transition from algorithm development to real-time implementation. The portability of the hardware makes it quick and easy to transport between test facilities. This hard ware/software architecture is flexible enough to support a variety of diagnostic applications and test hardware, and the GUI-based rapid prototyping capability is sufficient to support development execution, and testing of custom diagnostic algorithms. The PHALT operating system supports execution of diagnostic algorithms under real-time constraints. PHALT can perform real-time capture and playback of test rig data with the ability to augment/ modify the data stream (e.g. inject simulated faults). It performs algorithm testing using a variety of data input sources, including real-time data acquisition, test data playback, and system simulations, and also provides system feedback to evaluate closed-loop diagnostic response and mitigation control.

    The increasing focus on the costs of care is forcing health care organizations to critically look at their basic set of processes and activities, to determine what type of value they can deliver. A business model describes the resources, processes, and cost assumptions that an organization makes that will lead to the delivery of a unique value proposition to a customer. As health care organizations are beginning to transform their structure in preparation for a value-based delivery system, understanding business model theory can help in the redesign process.

    Introduction Integrated health systems are considered a solution to the challenge of maintaining the accessibility and integrity of healthcare in numerous jurisdictions worldwide. However, decision makers in a Canadian health region indicated they were challenged to find evidence-based information to assist with the planning and implementation of integrated healthcare systems. Methods A systematic literature review of peer-reviewed literature from health sciences and business databases, and targeted grey literature sources. Results Despite the large number of articles discussing integration, significant gaps in the research literature exist. There was a lack of high quality, empirical studies providing evidence on how health systems can improve service delivery and population health. No universal definition or concept of integration was found and multiple integration models from both the healthcare and business literature were proposed in the literature. The review also revealed a lack of standardized, validated tools that have been systematically used to evaluate integration outcomes. This makes measuring and comparing the impact of integration on system, provider and patient level challenging. Discussion and conclusion Healthcare is likely too complex for a one-size-fits-all integration solution. It is important for decision makers and planners to choose a set of complementary models, structures and processes to create an integrated health system that fits the needs of the population across the continuum of care. However, in order to have evidence available, decision makers and planners should include evaluation for accountability purposes and to ensure a better understanding of the effectiveness and impact of health systems integration.

    Understanding the state of a polar station's power system can be critical to a successful long-term deployment. Knowing how the system is functioning, prior to service, is key to proper logistics, scheduling and the service performed during a visit. A full record of power system performance is key to proper analysis of the health of the power system. The design of a power system with monitoring is a balance of components to gather information while still trying to keep complexity low. To properly incorporate a system to analyze a stations power system a firm understanding of how the power components function in polar environments as well as communication to data acquisition and / or telemetry is needed. For example designers will need to know how a station's power storage system will change in colder environments then manufactures standard design criteria. This would include the reduced available capacity, change in the mean time between failure and possible new failure modes. This understanding coupled with a system that would collect key information on the state of health of the power system will provide crucial insight in to what service is needed to keep the station functioning.

    The US population is at the beginning of a significant demographic shift; the American geriatric population is burgeoning, and average longevity is projected to increase in the coming years. Elder adults are affected by numerous chronic conditions, such as diabetes, hypertension, osteoarthritis, osteoporosis, cardiovascular diseases, and cerebrovascular diseases. These older adults need special dental care and an improved understanding of the complex interactions of oral disease and systemic chronic diseases that can complicate their treatment. Oral diseases have strong associations with systemic diseases, and poor oral health can worsen the impact of systemic diseases. PMID:25201543

    The Professional Health Card Public interest group (Groupement d'Intérêt Public-Carte de professionnel de Santé (GIP-CPS)) was founded in 1993 as a joint initiative by the different parties involved in health care in France: the state, the representatives of the health care professions and the compulsory and complementary health insurance organizations. The CPS system enables safe exchange and electronic sharing of medical data. Via Intranet connections and Extranet hosting of medical files, databases, the CPS system enables health care professionals who access servers to be identified with certainty. For email exhanges, the CPS systems guarantees the sender's identity and capacity. The electronic signature gives legal value to the email. The system also enables confidential email. The health card system (CPS) contributes to making the health service efficient. Shared medical files, health care networks, health warning systems or electronic requests for reimbursement of health insurance expenses all use the CPS system. More than 300,000 health care professionals use it regularly. The freedom of movement of patients throughout Europe has led to the growth of exchanges and information sharing between health professionals in the States of the Union. More and more health professionals will be leaving their own countries to work in foreign countries in the future. It is essential that their freedom of movement is accompanied by the ability to prove their rights to practice. PMID:16385785

    This paper describes the health system of Argentina.This system has three sectors: public, social security and private.The public sector includes the national and provincial ministries as well as the network of public hospitals and primary health care units which provide care to the poor and uninsured population. This sector is financed with taxes and payments made by social security beneficiaries that use public health care facilities. The social security sector or Obras Sociales (OS) covers all workers of the formal economy and their families. Most OS operate through contracts with private providers and are financed with payroll contributions of employers and employees. Finally, the private sector includes all those private providers offering services to individuals, OS beneficiaries and all those with private health insurance.This sector also includes private insurance agencies called Prepaid Medicine Enterprises, financed mostly through premiums paid by families and/or employers.This paper also discusses some of the recent innovations implemented in Argentina, including the program Remediar.

    It is well-documented that energy and energy systems have a central role in social and economic development and human welfare at all scales, from household and community to regional and national (41). Among its various welfare effects, energy is closely linked with people s health. Some of the effects of energy on health and welfare are direct. With abundant energy, more food or more frequent meals can be prepared; food can be refrigerated, increasing the types of food items that are consumed and reducing food contamination; water pumps can provide more water and eliminate the need for water storage leading to contamination or increased exposure to disease vectors such as mosquitoes or snails; water can be disinfected by boiling or using other technologies such as radiation. Other effects of energy on public health are mediated through more proximal determinants of health and disease. Abundant energy can lead to increased irrigation, agricultural productivity, and access to food and nutrition; access to energy can also increase small-scale income generation such as processing of agricultural commodities (e.g., producing refined oil from oil seeds, roasting coffee, drying and preserving fruits and meats) and production of crafts; ability to control lighting and heating allows education or economic activities to be shielded from daily or seasonal environmental constraints such as light, temperature, rainfall, or wind; time and other economic resources spent on collecting and/or transporting fuels can be used for other household needs if access to energy is facilitated; energy availability for transportation increases access to health and education facilities and allow increased economic activity by facilitating the transportation of goods and services to and from markets; energy for telecommunication technology (radio, television, telephone, or internet) provides increased access to information useful for health, education, or economic purposes; provision of energy

    Background: Hospitals are the central entity of each health care system and Health Promoting Hospitals (HPH) was launched by WHO in 1988. However, there has not been any accurate and detailed model for establishing a HPH in Iran up to now. Therefore, this study aimed to determine factors affecting the establishment of a health promoting hospital in Iran using factor analysis method. Methods: This applied, cross-sectional and descriptive-analytical study was conducted in Iran in four steps. Confirmatory Factor Analysis (CFA) was used for determining factors affecting the establishment of a HPH. Results: Society (0.97) and Policy (0.74) had the highest regression weights (effects) and management had the lowest one. Conclusion: Community assessment was the most important dimension of proposed conceptual model for establishing a HPH. PMID:27141499

    Sensor data are the basis for performance and health assessment of most complex systems. Careful selection and implementation of sensors is critical to enable high fidelity system health assessment. A model-based procedure that systematically selects an optimal sensor suite for overall health assessment of a designated host system is described. This procedure, termed the Systematic Sensor Selection Strategy (S4), was developed at NASA John H. Glenn Research Center in order to enhance design phase planning and preparations for in-space propulsion health management systems (HMS). Information and capabilities required to utilize the S4 approach in support of design phase development of robust health diagnostics are outlined. A merit metric that quantifies diagnostic performance and overall risk reduction potential of individual sensor suites is introduced. The conceptual foundation for this merit metric is presented and the algorithmic organization of the S4 optimization process is described. Representative results from S4 analyses of a boost stage rocket engine previously under development as part of NASA's Next Generation Launch Technology (NGLT) program are presented.

    The Risk Level Based Management System (RLBMS) is an occupational risk management (ORM) model that focuses occupational safety, hygeiene, and health (OSHH) resources on the highest risk procedures at work. This article demonstrates the model's simplicity through an implementation within a heavily regulated research institution. The model utilizes control banding strategies with a stratification of four risk levels (RLs) for many commonly performed maintenance and support activities, characterizing risk consistently for comparable tasks. RLBMS creates an auditable tracking of activities, maximizes OSHH professional field time, and standardizes documentation and control commensurate to a given task's RL. Validation of RLs and their exposure control effectiveness is collected in a traditional quantitative collection regime for regulatory auditing. However, qualitative risk assessment methods are also used within this validation process. Participatory approaches are used throughout the RLBMS process. Workers are involved in all phases of building, maintaining, and improving this model. This work participation also improves the implementation of established controls.

  17. INDUCTIVE SYSTEM HEALTH MONITORING WITH STATISTICAL METRICS

    2005-01-01

    Model-based reasoning is a powerful method for performing system monitoring and diagnosis. Building models for model-based reasoning is often a difficult and time consuming process. The Inductive Monitoring System (IMS) software was developed to provide a technique to automatically produce health monitoring knowledge bases for systems that are either difficult to model (simulate) with a computer or which require computer models that are too complex to use for real time monitoring. IMS processes nominal data sets collected either directly from the system or from simulations to build a knowledge base that can be used to detect anomalous behavior in the system. Machine learning and data mining techniques are used to characterize typical system behavior by extracting general classes of nominal data from archived data sets. In particular, a clustering algorithm forms groups of nominal values for sets of related parameters. This establishes constraints on those parameter values that should hold during nominal operation. During monitoring, IMS provides a statistically weighted measure of the deviation of current system behavior from the established normal baseline. If the deviation increases beyond the expected level, an anomaly is suspected, prompting further investigation by an operator or automated system. IMS has shown potential to be an effective, low cost technique to produce system monitoring capability for a variety of applications. We describe the training and system health monitoring techniques of IMS. We also present the application of IMS to a data set from the Space Shuttle Columbia STS-107 flight. IMS was able to detect an anomaly in the launch telemetry shortly after a foam impact damaged Columbia's thermal protection system.

    Within the analysis of the socio-economic context and the data from hospital discharges, the themes of social inequalities, health disparities, determinants of health care are discussed. Regular immigrants versus irregular, wealthy people versus those in poverty, they have access to and receive different health treatments, besides presenting risk conditions significantly different in relation to their social situation. Through the analysis of hospital discharge records as well as data from injuries at work, besides underestimations in foreign people and the greater risk of injuries for immigrants, it is evident how the aspects of inequalities connected to socioeconomic determinants and the different access to health services are pivotal for our health and welfare and that a profound change is required to tackle them properly, focusing on intervention on health care system, according to models which take into account not only evidence based medicine, but also narrative medicine, not only health protection, but also health promotion, so that equity and quality of health care is warranted for everyone.

    Due to the evident interaction between social factors and health, migrants are exposed to specific risk factors and access barriers to health services. Some examples are the lower education level, the low social position and/or the insufficient language skills. This concept is further elaborated in the multi-factorial impacts of health literacy. Female migrants often experience additional discrimination because of their gender. Despite the lack of representative data, consistent studies show that female migrants do not regularly take advantage of health care prevention and present themselves with higher degrees of stress. The current "inadequate health care" manifests itself in a lack of care in the areas of prevention and health education and an abundance in the context of medication and diagnostic procedures. To meet these demands and to further reduce barriers, in particular language barriers, specific strategies for this target group involving both politics and the health care system have to be developed. Besides the employment of interpreters with a native cultural background and the distribution of information booklets, it is an important strategy to reduce structural obstacles such as cultural diversity. To contact these women in their living environment should help to increase their self-determined health promotion. Selected models of good practice in Austria with regard to the themes of FGM (female genital mutilation), violence, heart disease and breast cancer are presented to highlight the specific health situation and risk factors of female migrants as well as successful strategies to confront them.

    Objective As healthcare systems continue to expand and interconnect with each other through patient sharing, administrators, policy makers, infection control specialists, and other decision makers may have to take account of the entire healthcare ‘ecosystem’ in infection control. Materials and methods We developed a software tool, the Regional Healthcare Ecosystem Analyst (RHEA), that can accept user-inputted data to rapidly create a detailed agent-based simulation model (ABM) of the healthcare ecosystem (ie, all healthcare facilities, their adjoining community, and patient flow among the facilities) of any region to better understand the spread and control of infectious diseases. Results To demonstrate RHEA's capabilities, we fed extensive data from Orange County, California, USA, into RHEA to create an ABM of a healthcare ecosystem and simulate the spread and control of methicillin-resistant Staphylococcus aureus. Various experiments explored the effects of changing different parameters (eg, degree of transmission, length of stay, and bed capacity). Discussion Our model emphasizes how individual healthcare facilities are components of integrated and dynamic networks connected via patient movement and how occurrences in one healthcare facility may affect many other healthcare facilities. Conclusions A decision maker can utilize RHEA to generate a detailed ABM of any healthcare system of interest, which in turn can serve as a virtual laboratory to test different policies and interventions.

    2016-01-01

    Background There are several frameworks that attempt to address the challenges of evaluation of health information systems by offering models, methods, and guidelines about what to evaluate, how to evaluate, and how to report the evaluation results. Model-based evaluation frameworks usually suggest universally applicable evaluation aspects but do not consider case-specific aspects. On the other hand, evaluation frameworks that are case specific, by eliciting user requirements, limit their output to the evaluation aspects suggested by the users in the early phases of system development. In addition, these case-specific approaches extract different sets of evaluation aspects from each case, making it challenging to collectively compare, unify, or aggregate the evaluation of a set of heterogeneous health information systems. Objectives The aim of this paper is to find a method capable of suggesting evaluation aspects for a set of one or more health information systems—whether similar or heterogeneous—by organizing, unifying, and aggregating the quality attributes extracted from those systems and from an external evaluation framework. Methods On the basis of the available literature in semantic networks and ontologies, a method (called Unified eValuation using Ontology; UVON) was developed that can organize, unify, and aggregate the quality attributes of several health information systems into a tree-style ontology structure. The method was extended to integrate its generated ontology with the evaluation aspects suggested by model-based evaluation frameworks. An approach was developed to extract evaluation aspects from the ontology that also considers evaluation case practicalities such as the maximum number of evaluation aspects to be measured or their required degree of specificity. The method was applied and tested in Future Internet Social and Technological Alignment Research (FI-STAR), a project of 7 cloud-based eHealth applications that were developed and

    A health monitoring system based on analytical redundancy is developed for satellites on elliptical orbits. First, the dynamics of the satellite including orbital mechanics and attitude dynamics is modelled as a periodic system. Then, periodic fault detection filters are designed to detect and identify the satellite's actuator and sensor faults. In addition, parity equations are constructed using the algebraic redundant relationship among the actuators and sensors. Furthermore, a residual processor is designed to generate the probability of each of the actuator and sensor faults by using a sequential probability test. Finally, the health monitoring system, consisting of periodic fault detection lters, parity equations and residual processor, is evaluated in the simulation in the presence of disturbances and uncertainty.

    2007-01-01

    Scientific Monitoring Inc. was awarded a Phase I Small Business Innovation Research (SBIR) project by NASA's Dryden Flight Research Center to create a new, simplified health-monitoring approach for flight vehicles and flight equipment. The project developed a hybrid physical model concept that provided a structured approach to simplifying complex design models for use in health monitoring, allowing the output or performance of the equipment to be compared to what the design models predicted, so that deterioration or impending failure could be detected before there would be an impact on the equipment's operational capability. Based on the original modeling technology, Scientific Monitoring released I-Trend, a commercial health- and performance-monitoring software product named for its intelligent trending, diagnostics, and prognostics capabilities, as part of the company's complete ICEMS (Intelligent Condition-based Equipment Management System) suite of monitoring and advanced alerting software. I-Trend uses the hybrid physical model to better characterize the nature of health or performance alarms that result in "no fault found" false alarms. Additionally, the use of physical principles helps I-Trend identify problems sooner. I-Trend technology is currently in use in several commercial aviation programs, and the U.S. Air Force recently tapped Scientific Monitoring to develop next-generation engine health-management software for monitoring its fleet of jet engines. Scientific Monitoring has continued the original NASA work, this time under a Phase III SBIR contract with a joint NASA-Pratt & Whitney aviation security program on propulsion-controlled aircraft under missile-damaged aircraft conditions.

  12. Health-weighted Composite Quality Metrics Offer Promise to Improve Health Outcomes in a Learning Health System.

    2013-01-01

    Health system leaders sometimes adopt quality metrics without robust supporting evidence of improvements in quality and/or quantity of life, which may impair rather than facilitate improved health outcomes. In brief, there is now no easy way to measure how much "health" is conferred by a health system. However, we argue that this goal is achievable. Health-weighted composite quality metrics have the potential to measure "health" by synthesizing individual evidence-based quality metrics into a summary measure, utilizing relative weightings that reflect the relative amount of health benefit conferred by each constituent quality metric. Previously, it has been challenging to create health-weighted composite quality metrics because of methodological and data limitations. However, advances in health information technology and mathematical modeling of disease progression promise to help mitigate these challenges by making patient-level data (eg, from the electronic health record and mobile health (mHealth) more accessible and more actionable for use. Accordingly, it may now be possible to use health information technology to calculate and track a health-weighted composite quality metric for each patient that reflects the health benefit conferred to that patient by the health system. These health-weighted composite quality metrics can be employed for a multitude of important aims that improve health outcomes, including quality evaluation, population health maximization, health disparity attenuation, panel management, resource allocation, and personalization of care. We describe the necessary attributes, the possible uses, and the likely limitations and challenges of health-weighted composite quality metrics using patient-level health data. PMID:25848572

    Sexual and reproductive health and rights (SRHR) are centrally important to health. However, there have been significant shortcomings in implementing SRHR to date. In the context of health systems reform and universal health coverage/care (UHC), this paper explores the following questions. What do these changes in health systems thinking mean for SRHR and gender equity in health in the context of renewed calls for increased investments in the health of women and girls? Can SRHR be integrated usefully into the call for UHC, and if so how? Can health systems reforms address the continuing sexual and reproductive ill health and violations of sexual and reproductive rights (SRR)? Conversely, can the attention to individual human rights that is intrinsic to the SRHR agenda and its continuing concerns about equality, quality and accountability provide impetus for strengthening the health system? The paper argues that achieving equity on the UHC path will require a combination of system improvements and services that benefit all, together with special attention to those whose needs are great and who are likely to fall behind in the politics of choice and voice (i.e., progressive universalism paying particular attention to gender inequalities).

    This article proposes a critical but non-systematic review of recent health care system reforms in developing countries. The literature reports mixed results as to whether reforms improve the financial protection of the poor or not. We discuss the reasons for these differences by comparing three representative countries: Mexico, Vietnam, and China. First, the design of the health care system reform, as well as the summary of its evaluation, is briefly described for each country. Then, the discussion is developed along two lines: policy design and evaluation methodology. The review suggests that i) background differences, such as social development, poverty level, and population health should be considered when taking other countries as a model; ii) although demand-side reforms can be improved, more attention should be paid to supply-side reforms; and iii) the findings of empirical evaluation might be biased due to the evaluation design, the choice of outcome, data quality, and evaluation methodology, which should be borne in mind when designing health care system reforms.

    2016-09-01

    As the basic sciences that inform conceptions of human health advance, so must the models that are used to frame additional research, to teach the next generation of providers, and to inform health policy. This article briefly reviews the evolution from a biomedical model to a biopsychosocial (BPS) model and to an ecobiodevelopmental (EBD) model. Like the BPS model, the EBD model reaffirms the biological significance of psychosocial features within the patient's ecology, but it does so at the molecular and cellular levels. More importantly, the EBD model adds the dimension of time, forcing providers to "think developmentally" and to acknowledge the considerable biological and psychological consequences of previous experiences. For the health care system to move from a reactive "sick care" system to a proactive "well care" system, all providers must begin thinking developmentally by acknowledging the dynamic but cumulative dance between nature and nurture that drives development, behavior, and health, not only in childhood, but across the lifespan.

  20. Evidence for integrating eye health into primary health care in Africa: a health systems strengthening approach

    PubMed Central

    2013-01-01

    Background The impact of unmet eye care needs in sub-Saharan Africa is compounded by barriers to accessing eye care, limited engagement with communities, a shortage of appropriately skilled health personnel, and inadequate support from health systems. The renewed focus on primary health care has led to support for greater integration of eye health into national health systems. The aim of this paper is to demonstrate available evidence of integration of eye health into primary health care in sub-Saharan Africa from a health systems strengthening perspective. Methods A scoping review method was used to gather and assess information from published literature, reviews, WHO policy documents and examples of eye and health care interventions in sub-Saharan Africa. Findings were compiled using a health systems strengthening framework. Results Limited information is available about eye health from a health systems strengthening approach. Particular components of the health systems framework lacking evidence are service delivery, equipment and supplies, financing, leadership and governance. There is some information to support interventions to strengthen human resources at all levels, partnerships and community participation; but little evidence showing their successful application to improve quality of care and access to comprehensive eye health services at the primary health level, and referral to other levels for specialist eye care. Conclusion Evidence of integration of eye health into primary health care is currently weak, particularly when applying a health systems framework. A realignment of eye health in the primary health care agenda will require context specific planning and a holistic approach, with careful attention to each of the health system components and to the public health system as a whole. Documentation and evaluation of existing projects are required, as are pilot projects of systematic approaches to interventions and application of best practices

    The purpose of this work is to present the preliminary results of research in progress on the design of an information system model that is capable of supporting prevention and control activities related to sexually transmitted diseases (STD) in a Mexican health jurisdiction. The project is being developed in the following five phases: 1) informetric indicators on the prevention and control of STD; 2) information flow models representing the access and use of information by the actors involved in the activities; 3) system analysis; 4) system design; and 5) implementation. Bibliometric/scientometric techniques have been applied to conduct the first phase of the project. A soft systems approach is to be conducted throughout phases 2-5. Austin and Kendall and Kendall criteria are to be used for system analysis, design, and implementation. Expected products and benefits include: a) a bibliographic database on the prevention and control of STD in Mexico; b) science policy indicators to improve decision making; c) an information system model/prototype; and d) the development of the soft systems methodology, as applied to improving information-problem-situations in a health system.

    The economic and social crises affecting Latin America have had a profound social and political effect on its structures. This paper analyzes this impact from 2 perspectives: 1) the impact on the apparatus of the state, in particular on its health infra-structures; and 2) the direction of the democratic process in the continent and the participatory processes of civil societies. The institutionalization of the Local Health Systems (SILOS) is an effort to analyze the problem from within the health sector and propose solutions. This paper discusses the issues of human resource development in health systems; training in human resource development and human resource development in local health care systems. There are 3 strategies used to change health systems: 1) The judicial-political system: The state's apparatus 2) The political-administrative system: the national health care system; and 3) the political-operative system: local health care systems. To assure implementation of SILOS there are 4 steps to be followed: 1) create political conditions that allow the transformation and development of local health systems; 2) development of high-level institutional and political initiatives to develop health care networks; 3) offer key players institutional space and social action to develop the SILOS process; 4) rapidly develop SILOS in regions to assure its integration with other development efforts. The labor force in the health sector and organized communities play critical roles in proposing and institutionalizing health programs. PMID:2766984

  3. Investing in health systems for universal health coverage in Africa

    Background This study focused on the 47 Member States of the World Health Organization (WHO) African Region. The specific objectives were to prepare a synthesis on the situation of health systems¿ components, to analyse the correlation between the interventions related to the health Millennium Development Goals (MDGs) and some health systems¿ components and to provide overview of four major thrusts for progress towards universal health coverage (UHC). Methods The WHO health systems framework and the health-related MDGs were the frame of reference. The data for selected indicators were obtained from the WHO World Health Statistics 2014 and the Global Health Observatory. Results African Region¿s average densities of physicians, nursing and midwifery personnel, dentistry personnel, pharmaceutical personnel, and psychiatrists of 2.6, 12, 0.5, 0.9 and 0.05 per 10 000 population were about five-fold, two-fold, five-fold, five-fold and six-fold lower than global averages. Fifty-six percent of the reporting countries had fewer than 11 health posts per 100 000 population, 88% had fewer than 11 health centres per 100 000 population, 82% had fewer than one district hospital per 100 000 population, 74% had fewer than 0.2 provincial hospitals per 100 000 population, and 79% had fewer than 0.2 tertiary hospitals per 100 000 population. Some 83% of the countries had less than one MRI per one million people and 95% had fewer than one radiotherapy unit per million population. Forty-six percent of the countries had not adopted the recommendation of the International Taskforce on Innovative Financing to spend at least US$ 44 per person per year on health. Some of these gaps in health system components were found to be correlated to coverage gaps in interventions for maternal health (MDG 5), child health (MDG 4) and HIV/AIDS, TB and malaria (MDG 6). Conclusions Substantial gaps exist in health systems and access to MDG-related health interventions. It is imperative that countries

    This paper explores some detailed mechanistic hypotheses for the possible action of acid particles on the tracheobronchial region of the human respiratory system. Because of the buffering capacity and volume of mucus produced per day it appears doubtful that ordinary ambient exposures to acid particles could markedly change the overall pH of tracheobronchial mucus considered as a whole. However, it is possible that individual acidic particles could contain enough acid to deliver localized irritant signals that could be the triggers for enhanced mucus secretion and cell division in sensitive portions of the bronchial tree, and thereby contribute to the processes involved in chronic bronchitis. Depending on the exact pH depression required for a signal to be perceived by the tracheobronchial epithelium, the acid content of the incoming particles per unit weight, and the effect of neutralization by ammonia in the upper respiratory tract, the minimum size of an acidic particle required to deliver a perceptible signal might range from about 0.4 to 0.7 microns for portions of the epithelium that are frequently swept by 4-micron mucus droplets. Since particle number per unit weight declines dramatically with increasing particle size, the most potent fraction of particles in terms of signals delivered per /sup +/g/m/sup 3/ is likely to be just above the minimum size that is needed to produce an effective signal. The model developed here makes predictions of the relative potency of particles of different size and acid delivery capacity that could be tested in both experimental animal systems and human epidemiological studies.

    Our current health care system is broken and unsustainable. Patients desire the highest quality care, and it needs to cost less. To regain public trust, the health care system must change and adapt to the current needs of patients. The diverse group of stakeholders in the health care system creates challenges for improving the value of care. Health care providers are in the best position to determine effective ways of improving the value of care. To create change, health care providers must learn how to effectively lead patients, those within health care organizations, and other stakeholders. This article presents servant leadership as the best model for health care organizations because it focuses on the strength of the team, developing trust and serving the needs of patients. As servant leaders, health care providers may be best equipped to make changes in the organization and in the provider-patient relationship to improve the value of care for patients. PMID:24486078

    The countries of the Commonwealth of Independent States differ substantially in their post-Soviet economic development but face many of the same challenges to health and health systems. Life expectancies dropped steeply in the 1990s, and several countries have yet to recover the levels noted before the dissolution of the Soviet Union. Cardiovascular disease is a much bigger killer in the Commonwealth of Independent States than in western Europe because of hazardous alcohol consumption and high smoking rates in men, the breakdown of social safety nets, rising social inequality, and inadequate health services. These former Soviet countries have embarked on reforms to their health systems, often aiming to strengthen primary care, scale back hospital capacities, reform mechanisms for paying providers and pooling funds, and address the overall shortage of public funding for health. However, major challenges remain, such as frequent private out-of-pocket payments for health care and underdeveloped systems for improvement of quality of care. PMID:23541055

    Dynamic modeling and simulation are systems science tools that examine behaviors and outcomes resulting from interactions among multiple system components over time. Although there are excellent examples of their application, they have not been adopted as mainstream tools in population health planning and policymaking. Impediments to their use include the legacy and ease of use of statistical approaches that produce estimates with confidence intervals, the difficulty of multidisciplinary collaboration for modeling and simulation, systems scientists’ inability to communicate effectively the added value of the tools, and low funding for population health systems science. Proposed remedies include aggregation of diverse data sets, systems science training for public health and other health professionals, changing research incentives toward collaboration, and increased funding for population health systems science projects.

    The present public health system has continually struggled to combat ongoing and emerging public health threats and emergencies. The main impediment to improving public health readiness is the lack of an effective Public Health Emergency Response System. Although many health systems have been built and large amount of data collected, it is hard to analyze these data in depth and use them efficiently. An effective PHEMS should be able to manage data, produce information and provide services. Based on digital city, such a PHEMS has a most possible chance to be built. Detailed analysis of the architecture of the PHEMS, including (1) the surveillance system for data collection, (2) the consolidated information model based on HL7 Reference Information Model (RIM), (3) and the public health service framework, is focused in this paper. As a test-bed, the implementation of a prototype, which is a part of Digital Beijing Pilot, is illustrated. In the end, some operational and technical difficulties are discussed.

    This report summarizes initial modeling of the local response of the Bigelow Expandable Activity Module (BEAM) to micrometeorite and orbital debris (MMOD) impacts using a structural, non-linear, transient dynamic finite element code. Complementary test results for a local BEAM structure are presented for both hammer and projectile impacts. Review of these data provided guidance for the transient dynamic model development. The local model is intended to support predictions using the global BEAM model, described in a companion report. Two types of local models were developed. One mimics the simplified Soft-Goods (fabric envelop) part of the BEAM NASTRAN model delivered by the project. The second investigates through-the-thickness modeling challenges for MMOD-type impacts. Both the testing and the analysis summaries contain lessons learned and areas for future efforts.

    Health research systems can link knowledge generation with practical concerns to improve health and health equity. Interest in health research, and in how health research systems should best be organised, is moving up the agenda of bodies such as the World Health Organisation. Pioneering health research systems, for example those in Canada and the UK, show that progress is possible. However, radical steps are required to achieve this. Such steps should be based on evidence not anecdotes. Health Research Policy and Systems (HARPS) provides a vehicle for the publication of research, and informed opinion, on a range of topics related to the organisation of health research systems and the enormous benefits that can be achieved. Following the Mexico ministerial summit on health research, WHO has been identifying ways in which it could itself improve the use of research evidence. The results from this activity are soon to be published as a series of articles in HARPS. This editorial provides an account of some of these recent key developments in health research systems but places them in the context of a distinguished tradition of debate about the role of science in society. It also identifies some of the main issues on which 'research on health research' has already been conducted and published, in some cases in HARPS. Finding and retaining adequate financial and human resources to conduct health research is a major problem, especially in low and middle income countries where the need is often greatest. Research ethics and agenda-setting that responds to the demands of the public are issues of growing concern. Innovative and collaborative ways are being found to organise the conduct and utilisation of research so as to inform policy, and improve health and health equity. This is crucial, not least to achieve the health-related Millennium Development Goals. But much more progress is needed. The editorial ends by listing a wide range of topics related to the above

    Clinicians and health systems are facing widespread challenges, including changes in care delivery, escalating health care costs, and the need to keep up with rapid scientific discovery. Reorganizing U.S. health care and changing its practices to render better, more affordable care requires transformation in how health systems generate and apply knowledge. The "rapid-learning health system"-posited as a conceptual strategy to spur such transformation-leverages recent developments in health information technology and a growing health data infrastructure to access and apply evidence in real time, while simultaneously drawing knowledge from real-world care-delivery processes to promote innovation and health system change on the basis of rigorous research. This article describes an evolving learning health system at Group Health Cooperative, the 6 phases characterizing its approach, and examples of organization-wide applications. This practical model promotes bidirectional discovery and an open mind at the system level, resulting in willingness to make changes on the basis of evidence that is both scientifically sound and practice-based. Rapid learning must be valued as a health system property to realize its full potential for knowledge generation and application. PMID:22868839

Transforming health care into a population health system requires methods for innovation and improvement that can work across professions and sectors. It may be possible to replicate improvement successes in healthcare settings within and across the broader systems of social, educational, and other human services that influence health outcomes in communities. Improvement methods could translate the rhetoric of collaboration, integration and alignment into practice across the fragmented health and human service sectors in the U.S. PMID:26699349

    Public health decision-making is critically dependent on the timely availability of sound data. The role of health information systems is to generate, analyse and disseminate such data. In practice, health information systems rarely function systematically. The products of historical, social and economic forces, they are complex, fragmented and unresponsive to needs. International donors in health are largely responsible for the problem, having prioritized urgent needs for data over longer-term country capacity-building. The result is painfully apparent in the inability of most countries to generate the data needed to monitor progress towards the Millennium Development Goals. Solutions to the problem must be comprehensive; money alone is likely to be insufficient unless accompanied by sustained support to country systems development coupled with greater donor accountability and allocation of responsibilities. The Health Metrics Network, a global collaboration in the making, is intended to help bring such solutions to the countries most in need. PMID:16184276

    Perspectives of development of the Tunisian health system are presented, in reference to the conceptual framework recommended by the World Health Organization, while a project of health insurance reform of the social security regimes is submitted to a dialogue with the different concerned parts. Recommended orientations articulate around five axes: 1. The promotion of care provision by improving the accessibility to services, notably in zones under served, by introducing new modes of dispensation, organization and management of care provision in the framework of a continuous quality assurance strategy. 2. The financing of health care, with the implementation of the health insurance reform, has to allow an improvement of the financial accessibility of the population to health care, while supervising the evolution of total health expenditures and by developing the system's management capacities. 3. Proposals relative to the mobilization of resources are advanced in areas of medicine, training of health professionals and research on the health system. 4. Adaptation of the health system governance to the new context is necessary and would have to be developed around evolving standards for the health system, on evaluation of its performances and on information and communication with its users. 5. The health system responsiveness, new motion whose contours are again blurred, would have to be analysed and adapted to the specific context of the country. PMID:11515474

    Human resources education for health workers has been predominantly discipline-oriented and fragmented, influencing research design and, in turn, scientific output. Several authors argue that university education should transition from disciplinarity to transdisciplinarity. To gather the theoretical underpinnings for this subject of international interest, a literature search was conducted in the PubMed, EBSCO, and SciELO databases in 2012, using the terms "transdisciplinary and translational research" in Spanish and English. The majority of authors believe that identifying problems from different perspectives by specialists and community members and leaders will be conducive to more effective intersectoral interventions. They suggest undertaking organizational change to reshape reshaping work styles and self-organizational forms of scientific activity. Finally, a transdisciplinary model for public health research has been proposed that is based on traditional project design tools, but with variations borrowed from a complex systems approach.

    Health Information Systems (HIS) are the core support to decision-making in health organizations. Within HIS, health indicators (HI) reflect, numerically, events measured in the health-illness continuum. The integrated health information system is intended to standardize, integrate and organize all the information available in health information systems through an accessible and secure repository, and to conveniently distribute information for decision-making. To standardize information it is necessary to define standards and semantic information to enable us to identify concepts and relate them uniquely to each other. The definition of a catalog of entities (DEA) with concepts, attributes and domains will enable the configuration of the information system, so there will be a catalog of entities (concepts of information and domains). Based on operational systems, analytical systems enabling management and strategy in the management of organizations will be built. The maximum level of analysis is the Balanced Score Card (BSC), which is established as the strategic tool for managers. It is necessary for the organization an integrated information system to plan, manage, evaluate and therefore provide managers with a decision tool for strategic and tactical decision-making in short and medium term.

At the same time, the economic liberalization policies which are in fashion accentuate social divisions and favor models of health care that are fragmented according to the economic means of the user.

    Background Intersectoral perspectives of health are present in the rhetoric of the sustainable development goals. Yet its descriptions of systematic approaches for an intersectoral monitoring vision, joining determinants of health, and barriers or facilitators to accessing healthcare services are lacking. Objective To explore models of associations between health outcomes and health service coverage, and health determinants and health systems responsiveness, and thereby to contribute to monitoring, analysis, and assessment approaches informed by an intersectoral vision of health. Design The study is designed as a series of ecological, cross-country regression analyses, covering between 23 and 57 countries with dependent health variables concentrated on the years 2002–2003. Countries cover a range of development contexts. Health outcome and health service coverage dependent variables were derived from World Health Organization (WHO) information sources. Predictor variables representing determinants are derived from the WHO and World Bank databases; variables used for health systems’ responsiveness are derived from the WHO World Health Survey. Responsiveness is a measure of acceptability of health services to the population, complementing financial health protection. Results Health determinants’ indicators – access to improved drinking sources, accountability, and average years of schooling – were statistically significant in particular health outcome regressions. Statistically significant coefficients were more common for mortality rate regressions than for coverage rate regressions. Responsiveness was systematically associated with poorer health and health service coverage. With respect to levels of inequality in health, the indicator of responsiveness problems experienced by the unhealthy poor groups in the population was statistically significant for regressions on measles vaccination inequalities between rich and poor.

    Health systems face the challenge of helping to improve health conditions. They occupy a priority place in middle- and lower-income countries, since the absence or fragility of health systems adversely impacts expected health outcomes. Thus, due to the direct relationship between programs and systems, the absence or weakness of either will result in a consequent deficiency in public health and the very execution of the programs. In the same vein, weakened health systems are one of the main bottlenecks to attaining the Millennium Development Goals. Systems thinking is one of the "four revolutions in progress" that are helping to transform health and health care systems. Within that framework, this article identifies conceptual and operational elements of systems applicable to health systems that contribute to overcoming the obstacles and inertia that hinder health activities and outcomes. It discusses relevant concepts characteristic of systems thinking, such as structural variables and dynamic complexity, the relationship between programs and health systems, and the monitoring and evaluation function, together with the role of innovation and systems integration as high-priority elements. This will aid in the development of designs that also stress the context of the components that guide management, identifying processes and outcomes in a health management continuum. PMID:26758004

    All public systems look for the best organizational structure to funnel part of their national income into healthcare services. Appropriate policies may differ widely across country settings. Most healthcare systems fall under one of two broad categories, either Bismark or Beveridge systems. There is no simple ideal model for the organization of health services, but most healthcare systems that follow the Beveridge healthcare model are poor performers. The Libyan Health system is a low responsive, inefficient and underperforming system that lacks goals and/or SMART. (Specific, Measurable, Achievable, Realistic, Time specific) objectives. A look at different organization models in the world would reinforce efforts to reorganize and improve the performance of the Libyan National Healthcare services. The French Health Care System (FHCS) ranked first according to the WHO and the European Health Consumer Powerhouse. The FHCS was described to have a technically efficient, generous healthcare system that provides the best overall health care. This makes the FHCS a practical model of organization having many of the essential aspects of a modern national health service. In this review, we describe the main features of the FHCS, current challenges and future trends with particular attention paid to aspects that could be of importance to the Libyan Healthcare System.

    Health systems in South America still support segmentation, privatization and fragmentation. Health reforms of the structural adjustment programs in the 1980s and 1990s in South America followed different purposes and strategies ranging from privatization, commodification and state intervention for the implementation of a national public health service with universal access as a right of the citizens. Since the 2000s, many countries have expanded social policies, reduced poverty and social inequalities, and improved access to healthcare. This article proposes to discuss the health systems in South America from historical and political backgrounds, and the progress from the reforms in the last three decades. It also presents the three paradigmatic models of reform and their evolution, as well as the contrasts between universal coverage and universal systems. Finally, it presents current strengths and weaknesses of the twelve South American health systems as well as current opportunities and challenges in health for UNASUR. PMID:25597728

    Background: Despite decades of disagreement among mental health practitioners and researchers in the Western world pertaining to the causation, classification and treatment of mental disorders there is an ongoing push to implement western mental health models in developing countries. Little information exists on the adaptability of western mental health models in developing countries. Method: This paper presents a review of the attempt to implement a western-oriented mental health system into a different culture, specifically a developing country such as Uganda. It draws upon an extensive literature review and the author’s work in Uganda to identify the lessons learned as well as the challenges of introducing a western-oriented mental health system in a totally new cultural milieu. Results: There is recognition by the national government that the challenges faced in mental health services poses serious public health and development concerns. Efforts have and are being made to improve services using the Western model to diagnose and treat, frequently with practitioners who are unfamiliar with the language, values and culture. Conclusions and Global Health Implications: Uganda can continue to implement the Western mental health practice model which emanates from a different cultural base, based on the medical model and whose tenets are currently being questioned, or establish a model based on their needs with small baseline in-country surveys that focus on values, beliefs, resiliency, health promotion and recovery. The latter approach will lead to a more efficient mental health system with improved care, better outcomes and overall mental health services to Ugandan individuals and communities.

  11. Gastrointestinal tract modelling in health and disease

    The gastrointestinal (GI) tract is the system of organs within multi-cellular animals that takes in food, digests it to extract energy and nutrients, and expels the remaining waste. The various patterns of GI tract function are generated by the integrated behaviour of multiple tissues and cell types. A thorough study of the GI tract requires understanding of the interactions between cells, tissues and gastrointestinal organs in health and disease. This depends on knowledge, not only of numerous cellular ionic current mechanisms and signal transduction pathways, but also of large scale GI tissue structures and the special distribution of the nervous network. A unique way of coping with this explosion in complexity is mathematical and computational modelling; providing a computational framework for the multilevel modelling and simulation of the human gastrointestinal anatomy and physiology. The aim of this review is to describe the current status of biomechanical modelling work of the GI tract in humans and animals, which can be further used to integrate the physiological, anatomical and medical knowledge of the GI system. Such modelling will aid research and ensure that medical professionals benefit, through the provision of relevant and precise information about the patient’s condition and GI remodelling in animal disease models. It will also improve the accuracy and efficiency of medical procedures, which could result in reduced cost for diagnosis and treatment. PMID:19132766

    In 1975, a group of professionals in Peru who were experts on national health systems began a process that led the country to be the first in South America to initiate a modern organization of the health system. This pioneering development meant that the creation of the National Health Services System [in Peru] in 1978 occurred before the health system reforms in Chile (1980), Brazil (1990), Colombia (1993), and Ecuador (2008). This encouraging start has had permanent reformist fluctuations since then, with negative development because of the lack of a State policy. Current features of the Peruvian system are inefficient performance, discontinuity, and lack of assessment, which creates a major setback in comparison with other health systems in America. In the 21st century, significant technical efforts have been missed to modernize the system and its functions. The future is worrying and the role of new generations will be decisive. PMID:25597729

    There is growing interest in comparing patterns of social and health service development in advanced Asian economies. Most publications concentrate broadly on a range of core social services such as education, housing, social security and health care. In terms of those solely focused on health, most discuss arrangements in specific countries and territories. Some take a comparative approach, but are focused on presentation and discussion of expenditure, resourcing and service utilization data. This article extends the comparative analysis of advanced Asian health systems, considering the cases of Japan, South Korea, Taiwan, Hong Kong and Singapore. The article provides basic background information, and delves into common concerns among the world's health systems today including primary care organization, rationing and cost containment, service quality, and system integration. Conclusions include that problems exist in 'classifying' the five diverse systems; that the systems face common pressures; and that there are considerable opportunities to enhance primary care, service quality and system integration.

    This paper gives four examples of health risk assessments of energy systems: (1) Comparative risk assessment of the health effects of the coal and nuclear fuel cycles. Estimates differ from previous values chiefly by inclusion of ranges of uncertainty, but some coal-cycle numbers were re-estimated. Upper-boundary public disease risks of air pollution from coal-fired plants dominate. Reactors probably account for most of the potential effect of major nuclear accidents. Accidental death rates in electricity generation are low for reactors and higher for coal. (2) Upper boundary air pollution health risks of existing fossil-based energy technologies in the United States. Preliminary mortality estimates were obtained combining potential impacts of three index pollutants - SO/sub 4/, NO/sub 2/, and CO - as independent measures of risk. Four fuel cycle trajectories leading to three end-uses were analyzed. Example results: domestic wood burning has substantial potential impact, with an upper boundary exceeding that of coal; upper-boundary air pollution impacts of gas can exceed those of oil, because of NO/sub 2/. (3) Health risks of acid deposition and other transported air pollutants, carried out as part of an assessment of the US Congress Office of Technology Assessment (OTA) Acid Rain and Transported Air Pollutants - Implications for Public Policy. Three scenarios were examined, leading to estimates of 40,000 to 50,000 annual premature deaths, depending on year (1978 vs 2000) and scenario (holding total emissions constant vs 30% reduction). (4) health effects of uranium mill tailings piles. Mortality risk is estimated to be minuscule (8.7 x 10/sup -9/ average individual lifetime cancer risk from a model mill, compared with 9.5 x 10/sup -4/ for background radiation). Methods that sum risks over the indefinite future are shown to be to be unrealistic. 39 references, 7 figures, 15 tables.

    Background: The emergence and evolution of socioeconomic inequalities in health involves multiple factors interacting with each other at different levels. Simulation models are suitable for studying such complex and dynamic systems and have the ability to test the impact of policy interventions in silico. Objective: To explore how simulation models were used in the field of socioeconomic inequalities in health. Methods: An electronic search of studies assessing socioeconomic inequalities in health using a simulation model was conducted. Characteristics of the simulation models were extracted and distinct simulation approaches were identified. As an illustration, a simple agent-based model of the emergence of socioeconomic differences in alcohol abuse was developed. Results: We found 61 studies published between 1989 and 2013. Ten different simulation approaches were identified. The agent-based model illustration showed that multilevel, reciprocal and indirect effects of social determinants on health can be modeled flexibly. Discussion and Conclusions: Based on the review, we discuss the utility of using simulation models for studying health inequalities, and refer to good modeling practices for developing such models. The review and the simulation model example suggest that the use of simulation models may enhance the understanding and debate about existing and new socioeconomic inequalities of health frameworks.

    The health reform legislation passed in March 2010 will introduce a range of payment and delivery system changes designed to achieve a significant slowing of health care cost growth. Most assessments of the new reform law have focused only on the federal budgetary impact. This updated analysis projects the effect of national reform on total national health expenditures and the insurance premiums that American families would likely pay. We estimate that, on net, the combination of provisions in the new law will reduce health care spending by $590 billion over 2010-2019 and lower premiums by nearly $2,000 per family. Moreover, the annual growth rate in national health expenditures could be slowed from 6.3 percent to 5.7 percent. PMID:20491172

    The Integrated Medical Model (IMM) captures organizational knowledge across the space medicine, training, operations, engineering, and research domains. IMM uses this knowledge in the context of a mission and crew profile to forecast risks to crew health and mission success. The IMM establishes a quantified, statistical relationship among medical conditions, risk factors, available medical resources, and crew health and mission outcomes. These relationships may provide an appropriate foundation for developing an in-flight medical decision support tool that helps optimize the use of medical resources and assists in overall crew health management by an autonomous crew with extremely limited interactions with ground support personnel and no chance of resupply.

  1. Why focus on mental health systems?

    The global situation for people with mental illness – in developing and developed countries – is dire. Legislative and human rights protections are frequently lacking. Mental health budgets are inadequate. There are insufficient numbers of skilled policy makers, managers and clinicians. Communities are poorly informed about mental health and illness and not well organised for purposes of advocacy. In most of the world, mental health services are inaccessible or of poor quality. Most people who would benefit from psychiatric treatment and rehabilitation do not have affordable access to such services. Leadership – at all levels – for mental health system development needs to be greatly strengthened. While mental health research attention and funds are devoted predominantly to neuroscience and clinical research, we believe that the highest global mental health research priority is mental health systems research. There is an urgent need to focus on the development of effective, appropriate, affordable mental health services. The evidence base for such development is currently weak. The International Journal of Mental Health Systems aims to stimulate greater attention to the central importance of building functioning mental health systems. Rapid publication and global reach through open access will make this journal a resource for all those who wish to contribute to such development. PMID:18271974

    The article briefly systematizes health care models, emphasizes the role of population surveys as a management tool and analyzes the specific case of the Brazilian Oral Health Survey (SBBrasil 2010) and its contribution to the consolidation process of health care models consistent with the principles of the Sistema Único de Saúde (SUS, Public Health Care System). While in legal terms SUS corresponds to a health care model, in actual practice the public policy planning and health action, the system gives rise to a care model which is not the result of legal texts or theoretical formulations, but rather the praxis of the personnel involved. Bearing in mind that the management of day-to-day health affairs is a privileged space for the production and consolidation of health care models, it is necessary to stimulate and support the development of technical and operational skills which are different from those required for the management of care related to individual demands.

    Special studies and isolated initiatives over the past several decades in low-, middle- and high-income countries have consistently shown inequalities in health among socioeconomic groups and by gender, race or ethnicity, geographical area and other measures associated with social advantage. Significant health inequalities linked to social (dis)advantage rather than to inherent biological differences are generally considered unfair or inequitable. Such health inequities are the main object of health development efforts, including global targets such as the Millennium Development Goals, which require monitoring to evaluate progress. However, most national health information systems (HIS) lack key information needed to assess and address health inequities, namely, reliable, longitudinal and representative data linking measures of health with measures of social status or advantage at the individual or small-area level. Without empirical documentation and monitoring of such inequities, as well as country-level capacity to use this information for effective planning and monitoring of progress in response to interventions, movement towards equity is unlikely to occur. This paper reviews core information requirements and potential databases and proposes short-term and longer term strategies for strengthening the capabilities of HIS for the analysis of health equity and discusses HIS-related entry points for supporting a culture of equity-oriented decision-making and policy development.

    Most health care management training programmes and textbooks focus on only one or two models or conceptual frameworks, but the increasing complexity of health care organizations and their environments worldwide means that a broader perspective is needed. This paper reviews five management models developed for business organizations and analyses issues related to their application in health care. Three older, more 'traditional' models are first presented. These include the functional areas model, the tasks model and the roles model. Each is shown to provide a valuable perspective, but to have limitations if used in isolation. Two newer, more 'innovative' models are next discussed. These include total quality management (TQM) and reengineering. They have shown potential for enabling dramatic improvements in quality and cost, but have also been found to be more difficult to implement. A series of 'lessons learned' are presented to illustrate key success factors for applying them in health care organizations. In sum, each of the five models is shown to provide a useful perspective for health care management. Health care managers should gain experience and training with a broader set of business management models. PMID:12476639

    The HIV/AIDS, tuberculosis and malaria pandemics pose substantial challenges globally and to health systems in the countries they affect. This demands an institutional approach that can integrate disease control programmes within health and social care systems. Whilst integration is intuitively appealing, evidence of its benefits remains uncertain and evaluation is beset by lack of a common understanding of what it involves. The aim of this paper is to better define integration in health systems relevant to communicable disease control. We conducted a critical review of published literature on concepts, definitions, and analytical and methodological approaches to integration as applied to health system responses to communicable disease. We found that integration is understood and pursued in many ways in different health systems. We identified a variety of typologies that relate to three fundamental questions associated with integration: (1) why is integration a goal (that is, what are the driving forces for integration); (2) what structures and/or functions at different levels of health system are affected by integration (or the lack of); and (3) how does integration influence interactions between health system components or stakeholders. The frameworks identified were evaluated in terms of these questions, as well as the extent to which they took account of health system characteristics, the wider contextual environment in which health systems sit, and the roles of key stakeholders. We did not find any one framework that explicitly addressed all of these three questions and therefore propose an analytical framework to help address these questions, building upon existing frameworks and extending our conceptualization of the 'how' of integration to identify a continuum of interactions that extends from no interactions, to partial integration that includes linkage and coordination, and ultimately to integration. We hope that our framework may provide a basis for

    This report presents the results of work on communications systems modeling and covers three different areas of modeling. The first of these deals with the modeling of signals in communication systems in the frequency domain and the calculation of spectra for various modulations. These techniques are applied in determining the frequency spectra produced by a unified carrier system, the down-link portion of the Command and Communications System (CCS). The second modeling area covers the modeling of portions of a communication system on a block basis. A detailed analysis and modeling effort based on control theory is presented along with its application to modeling of the automatic frequency control system of an FM transmitter. A third topic discussed is a method for approximate modeling of stiff systems using state variable techniques.

    We describe a clinical research visit scheduling system that can potentially coordinate clinical research visits with patient care visits and increase efficiency at clinical sites where clinical and research activities occur simultaneously. Participatory Design methods were applied to support requirements engineering and to create this software called Integrated Model for Patient Care and Clinical Trials (IMPACT). Using a multi-user constraint satisfaction and resource optimization algorithm, IMPACT automatically synthesizes temporal availability of various research resources and recommends the optimal dates and times for pending research visits. We conducted scenario-based evaluations with 10 clinical research coordinators (CRCs) from diverse clinical research settings to assess the usefulness, feasibility, and user acceptance of IMPACT. We obtained qualitative feedback using semi-structured interviews with the CRCs. Most CRCs acknowledged the usefulness of IMPACT features. Support for collaboration within research teams and interoperability with electronic health records and clinical trial management systems were highly requested features. Overall, IMPACT received satisfactory user acceptance and proves to be potentially useful for a variety of clinical research settings. Our future work includes comparing the effectiveness of IMPACT with that of existing scheduling solutions on the market and conducting field tests to formally assess user adoption. PMID:23684593

    Although mental disorders are a major public health problem, the development of mental health services has been a low priority everywhere, particularly in low- and middle-income countries. Recent years have seen a growing understanding of the importance of population mental health and increased attention to the need to develop mental health systems for responding to population mental health service needs. In countries and regions where mental health services are all but nonexistent, and in postconflict and postdisaster settings, there are many impediments to establishing or scaling up mental health services. It is frequently necessary to act simultaneously on multiple fronts: generating local evidence that will inform decision makers; developing a policy framework; securing investment; determining the most appropriate service model for the context; training and supporting mental health workers; establishing or expanding existing services; putting in place systems for monitoring and evaluation; and strengthening leadership and governance capabilities. This article presents the approach of the Centre for International Mental Health in the Melbourne School of Population Health to mental health system development, and illustrates the way in which the elements of the program are integrated by giving a brief case example from Sri Lanka.
