title: Family practitioners' remuneration and patterns of care--does social class matter?
abstract: The objective of the study is to examine whether medical care patterns and/or outcomes for patients under a prepaid system differ from those under fee-for-service according to social class. An effect of this kind was suggested by the investigators reporting on the RAND Health Insurance Experiment (RAND HIE). We performed a cross-sectional study in family practice in Germany (fee-for-service) and the UK (predominantly capitation i.e. prospective payment). 778 attending patients aged 18 and above were included. Indicators of care, relating mainly to cardiovascular prevention, were collected by patient interview and questionnaire, doctor's questionnaire, analysis of records, and blood pressure (BP) measurement. Multiple linear and logistic regression models with these indicators as dependent variables were calculated to examine possible interactions between social class and system of payment. Social class as a main effect was related to diastolic BP, BP measurement frequency, and the number of non-pharmacological interventions to lower BP. The data on the process and the outcome of primary care from British and German family practice do not show any significant interaction between system of family practitioners' remuneration and patients' social class. We were unable to reproduce the effect postulated by the RAND HIE investigators.
