Abstract:
Claims data-based studies provide insight into the delivery of health care services within the statutory health insurance (SHI) system. So far discretionary decisions concerning the definition of service utilization are seldom discussed. Using claims data of 9 147 dementia patients insured with AOK Bavaria SHI fund as an example, this paper compares different definitions of service utilisation and the corresponding costs of care. In total, the different approaches do not always result in different figures. Indeed the observed variation depends on the relative frequency of equivocally interpretable services within the study sample. Based on these results it is possible to provide recommendations for future standards for claims data analyses.
