Private health care provision in developing countries: a preliminary analysis of levels and composition.
(25/4815)
While the importance of the private sector in providing health services in developing countries is now widely acknowledged, the paucity of data on numbers and types of providers has prevented systematic cross-country comparisons. Using available published and unpublished sources, we have assembled data on the number of public and private health care providers for approximately 40 countries. This paper presents some results of the analysis of this database, looking particularly at the determinants of the size and structure of the private health sector. We consider two different types of dependent variable: the absolute number of private providers (measured here as physicians and hospital beds), and the public-private composition of provision. We examine the relationship between these variables and income and other socioeconomic characteristics, at the national level. We find that while income level is related to the absolute size of the private sector, the public-private mix does not seem to be related to income. After controlling for income, certain socioeconomic characteristics, such as education, population density, and health status are associated with the size of the private sector, though no causal relationship is posited. Further analysis will require more complete data about the size of the private sector, including the extent of dual practice by government-employed physicians. A richer story of the determinants of private sector growth would incorporate more information about the institutional structure of health systems, including provider payment mechanisms, the level and quality of public services, the regulatory structure, and labour and capital market characteristics. Finally, a normative analysis of the size and growth of the private sector will require a better understanding of its impact on key social welfare outcomes. (+info)
Sustainability of health care: a framework for analysis.
(26/4815)
This paper introduces a conceptual framework which can be used to study the sustainability of health services in developing countries. A health service is considered sustainable when operated by an organizational system with the long-term ability to mobilize and allocate sufficient resources for activities that meet individual or public health needs. The framework includes three clusters: (1) contextual factors, which outline the task and general environment of the services; (2) an activity profile, which describes the services delivered and the activities carried out to deliver them; and (3) organizational capacity, which shows the carrying ability (capability) of the organization in broad terms. In this framework, health care provision is seen as an open system model where five main factors determine how inputs are converted to outputs, linking them through feedback loops. These factors are aims, technology, structure, culture and process. The framework has proven useful in analyzing factors critical to sustainability, and in describing structures and processes both in basic public services and in private not-for-profit services. It should also be tested on more complex systems, such as national health care. (+info)
The ability to search bibliographic databases effectively is now an essential skill for anyone undertaking research in health. This article discusses the way in which databases are constructed and some of the important steps in planning and carrying out a search. Consideration is given to some of the advantages and limitations of searching using both thesaurus and natural language (textword) terms. A selected list of databases in health and medicine is included. (+info)
Glycemic control in patients with diabetes in Finland.
(28/4815)
OBJECTIVE: To evaluate the quality of diabetes care at a national level in Finland, using level of glycemia as a determinant of success in treatment. RESEARCH DESIGN AND METHODS: Physicians and diabetes nurses in 76 randomly selected clinics (59 primary care units and 17 hospitals) evenly covering the whole of Finland were asked to fill in a questionnaire asking for data based on the 1993 medical records of a random sample of 50 diabetic patients from each center (total n = 3,800). HbAlc was used as an index of glycemic control. RESULTS: Information on 3,195 (84%) diabetic patients was received. HbAlc was measured in 67% of the patients in 1993. The mean HbAlc in the whole population was 8.6 +/- 1.9% (normal range 4-6%). Some 25% of patients had HbAlc < or = 7.3%, while 25% had HbAlc > or = 9.7%. The mean HbAlc was 8.8 +/- 1.9% in type 1 and 8.5 +/- 1.9% in type 2 diabetic patients. There was no sex difference in the HbAlc level in type 1 diabetic patients. However, male type 2 diabetic patients had better glycemic control than female patients (8.3 +/- 1.9 vs. 8.8 +/- 1.9%, P < 0.0001). The sex difference was independent of the type of therapy. The mean level of glycemic control was lowest among individuals with the shortest duration of diabetes. After 7-9 years after the diagnosis, there was no change in the mean level of glycemia. CONCLUSIONS: Average glycemic control is poor in a majority of the diabetic patients in Finland. Better treatment strategies and methods should be used to improve glycemic control and to reduce long-term complications. (+info)
Beyond "compliance" is "adherence". Improving the prospect of diabetes care.
(29/4815)
The purpose of this study is to evaluate existing research in the area of patient "compliance," to endorse reconceptualizing "compliance" in terms of "adherence," and to discuss the benefits of such a change for medical practitioners. This study critically reviews existing medical, nursing, and social scientific research in the area of patient "compliance." We assert that the literature reviewed is flawed in its focus on patient behavior as the source of "noncompliance," and neglects the roles that practitioners, the American medical system, and patient-practitioner interaction play in medical definitions of "compliance." The term "compliance" suggests a restricted medical-centered model of behavior, while the alternative "adherence" implies that patients have more autonomy in defining and following their medical treatments. We suggest that while the change in terminology is minor, it reflects an important paradigmatic shift for thinking about the delivery of health care. By enabling practitioners to more accurately identify patients' social and economic constraints and to provide them with more efficient educational and financial resources, this type of change will improve patient care. In general, by moving to a more social paradigm for understanding patient behavior, practitioners can expand the types of explanations, and therefore the types of solutions, they have for therapeutic adherence.

Noncommunicable disease management in resource-poor settings: a primary care model from rural South Africa.
(30/4815)
Noncommunicable diseases (NCDs) such as hypertension, asthma, diabetes and epilepsy are placing an increasing burden on clinical services in developing countries and innovative strategies are therefore needed to optimize existing services. This article describes the design and implementation of a nurse-led NCD service based on clinical protocols in a resource-poor area of South Africa. Diagnostic and treatment protocols were designed and introduced at all primary care clinics in the district, using only essential drugs and appropriate technology; the convenience of management for the patient was highlighted. The protocols enabled the nurses to control the clinical condition of 68% of patients with hypertension, 82% of those with non-insulin-dependent diabetes, and 84% of those with asthma. The management of NCDs of 79% of patients who came from areas served by village or mobile clinics was transferred from the district hospital to such clinics. Patient-reported adherence to treatment increased from 79% to 87% (P = 0.03) over the 2 years that the service was operating. The use of simple protocols and treatment strategies that were responsive to the local situation enabled the majority of patients to receive convenient and appropriate management of their NCD at their local primary care facility.

The changing US health care system: challenges for responsible public policy.
(31/4815)
The "managed care backlash" arguably topped the list of media and policy concerns in 1998. Yet, against the background of the highly charged environment in which the future of our health care system continues to be debated, there is a dearth of concrete, "objective" facts on the nature of the changes, the reasons for them, and their meaning. An analysis of five important themes that emerged from a review of the recent literature on health system change concludes that an inherent tension exists between the interest in rapidly driving down health care costs through organizational change and the long time frames that are required to make fundamental changes in structure, process, and orientation. Unfortunately, in an environment in which purchasers are driven to seek cost savings and the political will supports a pluralistic and mixed public/private system, the health system may chart an alternative course, with the result that purchasers may rely increasingly on individual cost sharing and continue to cut back the amount of coverage they are willing to offer. The real challenge for public policy makers is to confront the issues directly, avoiding political incentives to adopt easy and fast solutions for these complex matters. (+info)
Developing a model to reduce blindness in India: The International Centre for Advancement of Rural Eye Care.
(32/4815)
With the continuing high magnitude of blindness in India, fresh approaches are needed to effectively deal with this burden on society. The International Centre for Advancement of Rural Eye Care (ICARE) has been established at the L.V. Prasad Eye Institute in Hyderabad to develop such an approach. This paper describes how ICARE functions to meet its objective. The three major functions of ICARE are design and implementation of rural eye-care centres, human resource development for eye care, and community eye-health planning. ICARE works with existing eye-care centres, as well as those being planned, in underserved areas of India and other parts of the developing world. The approach being developed by ICARE, along with its partners, to reduce blindness is that of comprehensive eye care with due emphasis on preventive, curative and rehabilitative aspects. This approach involves the community in which blindness is sought to be reduced by understanding how the people perceive eye health and the barriers to eye care, thereby enabling development of strategies to prevent blindness. Emphasis is placed on providing good-quality eye care with attention to reasonable infrastructure and equipment, developing a resource of adequately trained eye-care professionals of all cadres, developing a professional environment satisfactory for patients as well as eye-care providers, and the concept of good management and financial self-sustainability. Community-based rehabilitation of those with incurable blindness is also part of this approach. ICARE plans to work intensively with its partners and develop these concepts further, thereby effectively bringing into practice the concept of comprehensive eye care for the community in underserved parts of India, and later in other parts of the developing world. In addition, ICARE is involved in assessing the current situation regarding the various aspects of blindness through well-designed epidemiologic studies, and projecting the eye-care needs for the future with the help of reliable information. With balanced attention to infrastructure, manpower, financial self-sustenance, and future planning, ICARE intends to develop a practical model to effectively reduce blindness in India on a long-term basis.
