An overview of health financing patterns and the way forward in the WHO African Region

BACKGROUND

The way a health system is financed affects the performance of its other functions of stewardship, input (or resource) creation and services provision, and ultimately, the achievement of health system goals of health improvement (or maintenance), responsiveness to people's non-medical expectations and fair financial contributions.

OBJECTIVES

To analyse the changes between 1998 and 2002,in health financing from various sources; and to propose ways of improving the performance of health financing function in the WHO African Region.

DESIGN

A retrospective analysis of data obtained from the World Health Report, 2005.

METHODS

The analysis reported in this paper is based on the National Health Accounts (NHA) data for the 46 WHO Member States in the African Region. The data were obtained from the World Health Report 2005. It consisted of information on: levels of per capita expenditure on health; total expenditure on health as a percentage of gross domestic product (GDP); general government expenditure on health as a percentage of total expenditure on health; private expenditure on health as a percentage of total expenditure on health; general government expenditure on health as a percentage of total government expenditure; external expenditure as a percentage of total expenditure on health; social security expenditure on health as a percentage of general government expenditure on health; out-of-pocket expenditure as a percentage of private expenditure on health; and private prepaid plans as a percentage of private expenditure on health. The analysis was done using Lotus SmartSuite software.

RESULTS

The analysis revealed that: fifteen countries spent less than 4.5% of their GDP on health; forty four countries spent less than 15% of their national annual budget on health; sixty three percent of the governments in the Region spent less than US$10 per person per year; fifty per cent of the total expenditure on health in 24 countries came from government sources; prepaid health financing mechanisms cover only a small proportion of populations in the Region; private spending constituted over 40% of the total expenditure on health in 31; direct out-of-pocket expenditures constituted over 50% of the private health expenditure in 38 countries.

CONCLUSION

Every country needs to develop clear pro-poor health financing policy and a comprehensive health financing strategic plan with a clear roadmap of how it plans to transit from the current health financing state dominated by inequitable, catastrophic and impoverishing direct out-of-pocket payments to a visionary scenario of universal coverage. The strategic plan should strengthening of health sector advocacy and health financing capacities, health economics evidence generation and utilisation in decision-making, making better use of available and expected resources, monitoring of equity in financing, strengthening of the exemption mechanisms, managed removal of direct out-of-pocket payments (for countries that choose to), and improving country-led sectoral coordination mechanisms (e.g. Sector Wide Approaches).

Health status during the transition in Central and Eastern Europe: development in reverse?

This paper reports on a study of the cross-national trends in health status during the economic transition and associated health sector reforms in Central and Eastern Europe (CEE). The central premise is that before long-run gains in health status are realized, the transition towards a market economy and adoption of democratic forms of government should lead to short-run deterioration as a result of: (i) reduction in real income and widening income disparities; (ii) stress and stress-related behaviour; (iii) lax regulation of environmental and occupational risks; and (iv) breakdown in basic health services. Analysis focused on three broad indicators of health status: life expectancy at birth, infant mortality rate and the probability of dying between the ages of 15 and 65 years, shown by the notation '50q15'. The study revealed significant new information about health status and the health sector which could not have been obtained without a proper cross-national study. Infant mortality rates in former socialist economies (FSE) follow the global trend, declining as per capita income rises. However, rates are lower than would be predicted given their income levels. Despite declining infant mortality, life expectancy at birth in the former socialist economies decreases as per capita income rises, in marked contrast to global trends. This is because rising income level is associated with greater probability of death between the ages of 15 and 65: the wealthier the society, the less healthy is its population, particularly for its males. Causes of death in the FSE follow global trends: higher death rates due to infectious and parasitic diseases in poorer countries, and higher death rates due to chronic diseases in wealthier countries. However, age-standardized death rates for chronic diseases generally associated with unhealthy lifestyles and environmental risk factors are very high when compared with wealthier established market economies (EME). Policies and procedures which alter the effectiveness of health services have had a demonstrable but mixed impact on health status during the early phase of transition. Effective preventive health strategies must be formulated and implemented to reverse the adverse trends observed in Central and Eastern Europe.

The role of protocols and professional judgement in emergency medical dispatching

The task of evaluating incoming calls to Emergency Medical Services (EMS) systems in order to determine the most appropriate response is performed in many different ways in current EMS systems. At one end of the spectrum, the process is entirely dependent on the judgement of professionals, while at the other end protocols specify the exact questions to be asked and corresponding decisions. This case study describes the experience of the Montreal EMS system, Urgences santé, where professional telephone evaluation performed by nurses since 1981 was replaced by a protocolized system in 1992. During the professional era, there were many attempts to formalize the nurses' decision-making process. These first revealed that professional judgement tended to override decision-support tools that did not allow a flexible processing of the information spontaneously provided by callers. Second, the choice of a single protocol for each call was unnatural for professionals who could spontaneously integrate multiple aspects of a problem in parallel. Third, when protocols were used by professionals, it was a posteriori in order to document their decisions rather than actually support them. Fourth, the use of Artificial Intelligence (AI) methods in order to formalize professional judgement revealed its great complexity, which was confirmed by cognitive analyses of the nurses' decision-making processes. In particular, decisions of not sending EMS resources seemed to be the most difficult. These unsuccessful attempts at formalizing professional judgement led to an evaluation of its performance in terms of results, i.e. to which extent actual decisions minimized errors (both false positives and false negatives) and decision times. A random sample of 1006 calls was collected and the ideal decision was determined by concensus of experts for each call based on the patient's clinical condition. This theoretical decision was considered as a goal standard to which actual decisions were compared. Data analysis revealed that sensitivity of telephone triage (i.e. decision to send EMS resources or not) was almost perfect and specificity was 0.55. The necessary compromise between sensitivity and specificity varied with the types of decisions. Decision times were related to the urgency of the situations, more urgent calls being processed more rapidly. These results were interpreted as representing sophisticated optimization processes in professional judgement. The professional system was replaced by a non-professional protocolized system in 1992. This new system has not yet been formally evaluated in terms of results, but many sources of evidence suggest that it was accompanied by a deterioration of performance. Many contextual factors influence the organization of telephone assessment in EMS systems. This case study suggests that professional judgement may be most useful in contexts where the demand for EMS services often exceeds the availability of resources. On the other hand, protocolized systems may be more appropriate in the absence of such constraints, and where the litigation context prohibits the occurrence of any false negative.
