Structures and quality assurance of preventive care and health promotion in Germany

In order to identify requirements of quality assurance in this field, a general description of prevention, health promotion and education is outlined, based upon healthcare supply analyses and 158 interviews with experts. Prominent features are, among others, a distinctive heterogeneity and complexity of settings, suppliers, and interventions; supply of coverage is below public health criteria (needs); weak outcome evaluation; competition among suppliers, providers, and political agencies and decision makers; need for intra- and intersectoral coordination; the lack of evidence-based healthcare planning; and hurdles for quality assurance. A structural taxonomy of quality assurance systems is then developed, consisting of three dimensions: validity (quality of information), regularity, and degree of commitment and obligation. In terms of these dimensions, important systems of quality assurance in prevention, health promotion and education in Germany are analyzed. A number of different systems and approaches can be found. However, most of them share questionable validity, regularity, and degree of obligation. Increased commitment on behalf of providers, suppliers, and political institutions and decision makers for the quality of preventive interventions is inevitable in order to raise the performance of prevention and health promotion in Germany to their potential effectiveness.
