For example, in Stockholm county council about 40% of the payment is based on capitation, 55% on variable fee-for-service, and 3% is performance-related. In other county councils, between 80-98% of the payment is based on capitation. The risk-adjusted formulas used for determining capitation payments also vary between counties, from simple formulas based on age and gender to more complex formulas incorporating health status, prior use of services and socio-economic need. Such schemes include government or locally funded incentives for attaining specified priorities.
