Primary care in western Europe is delivered by general practitioners (
GPs) but their role within the overall health system is poorly underst
ood. The aim of this article is to present an overview of the characte
ristics of general practice in the context of health systems and to de
scribe their variability and interrelationships. Data were obtained fr
om two main sources: publications of official organizations and EC res
earch projects. The characteristics of general practice are described
and analysed with regard to three features: mode of payment, gatekeepe
r function and practice organization and workload. Despite their focus
on general practice as the cornerstone of the health system, western
European countries differ considerably in the major characteristics of
primary care. There is variability in the ratio of GPs to population
and in the extent to which patients relate to individual physicians. A
lthough all countries have universal health insurance, the mode of pay
ment of GPs differs. In some countries, the gatekeeper function of gen
eral practice is more highly developed and the use of specialist servi
ces varies accordingly. Practice characteristics such as workload, len
gth of consultation, ordering of tests and reappointments also vary wi
th differences in payment and gatekeeping arrangements. In particular,
fee-for-service was associated with weaker physician-patient relation
ships, reduced attractiveness of general practice, more home visiting
and longer consultations. Strong gatekeeping arrangements are not inco
mpatible with high public satisfaction and are associated with lower v
isit rates. However, strong gatekeeping is not characteristic of fee-f
or-service arrangements. These findings suggest a need for more concer
ted research that could inform policy decisions concerning primary car
e in the USA as well as in Europe.
