Relationship between risk assessment and payment models in Swedish Public Dental Service: a prospective study
2017
Abstract Background To a) compare risk categories in patients selecting a capitation payment (CP) model with those in fee-for-service (FFS), b) determine the 3-year caries increment in the two groups, and c) compare the amount of delivered preventive care in the two groups. Methods A comprehensive risk assessment was carried out in 1295 young adults attending eight Public Dental Clinics in the Scania region and 75% could be re-examined after 3 years; 615 had selected the CP model and 310 the traditional FFS. Caries was scored according to WHO and data concerning preventive care was extracted from the dental records. Results More patients in the low risk category preferred the CP model (74% vs. 26%) while >80% with high risk selected FFS. The baseline caries level was significantly higher in the FFS group as well as the 3-year caries increment (1.6 vs. 0.8 DFS: p Conclusions Young adults in public dental care with low risk preferred the prepaid model while those in the higher risk categories selected fee-for-service. As more additional preventive care was delivered to patients in the subscribed care, oral health planners and decision makers should be aware of the fact that capitation payment models may enhance inequalities in dental health over time.
