Abstract

Background: The risk compensation scheme (RCS) in the Statutory Health Insurance (SHI) was implemented in 1994 to discourage risk selection between sickness funds. However, several expertise papers have concluded since then that the sociodemographic risk adjusters in place could not adequately curb risk selection. To minimise incentives for risk selection in the Statutory Health Insurance (SHI) further, the RCS was refined in 2009 by adding 80 diseases as additional risk adjusters. In spite of the better compensation of differences in morbidity, however, incentives for risk selection may still persist. In this study, we investigated the association of indicators such as region (number of inhabitants in the city), income, level of education and family status (children in the household) with health care costs to determine if risk selection is still attractive for sickness funds under the refined RCS. Method: The analysis is based on a 2002 cross-section survey comprising 75 122 individuals. Health expenditures were estimated using self-documented utilisation data and were standardised for age, sex and diagnoses covered by the risk adjustment scheme. We included costs for inpatient care, outpatient care, pharmaceuticals, rehabilitation, and medical devices. To assess the effects of the above-mentioned individual characteristics on health-care expenditure, regression analyses and analyses of variances were performed. Results: Full documentation was available for 52 484 individuals (69.86%). From these the variables family status (children in the household), higher educational level, and higher income were associated with lower costs for individuals without chronic conditions. For individuals with chronic conditions, results were mixed. Family status, education and income showed no clear association with lower or higher costs and were not statistically significant. The variable region was neither significantly associated with chronically ill nor for healthy individuals. Discussion: With respect to age, sex, and morbidity, individuals with high income and education and without chronic diseases apparently cause lower costs. Thus, health status, income and education remain as possible selection criteria for sickness funds in Germany. However, the refined RCS compensates for the largest proportion of cost differences between insured with and without chronic disease. Possible causes of the small but remaining differences and whether improving preventive programmes or providing awareness campaigns may be appropriate strategies to tackle this issue should be investigated in future research.
