[Evaluation of cost effectiveness in primary health care]

Evaluation of Cost-Effectiveness in Health Care considers the background, methodology and potential political influence of economic evaluation (EE) in health care, the following conclusions can be drawn: EE is not just about cost cutting--it considers both costs and outcomes. EE needs to be integrated with decision-making procedures at different levels, namely the macro (policy) level, the meso (management) level, and the micro (clinical) level. EE needs to be seen as a part of a broader effort in health technology assessment and in relation to parallel efforts, e.g. guidelines development, quality assurance, evidence-based medicine. EE needs to be methodologically sound, but is not always possible to undertake the perfect study due to constraints of resources, time, information availability. Ways of setting priorities for EE need to be developed; this means selecting relevant topics and researchable questions. EE needs to be locally relevant; this means taking into account the variations of setting--within and between countries--and differences between trials (efficacy) and regular practice (community effectiveness). Factors that either encourage or inhibit the adoption of study results, i.e. adequate dissemination, professional support, financial incentives or political will, have to be considered.
