[High utilization of health insurance services by the elderly--analysis of hospital and drug utilization data].
The present contribution discusses the utilization of the healthcare system by elderly patients in Germany. First, the paper focuses on the detailed characterization of a group of people aged 60 years or more (N = 73,454). Second, the objective is to analyze the data for high utilization of healthcare services by older men and women. The analysis is based on data regularly recorded by a German health insurance agency for the year 2000. High utilization is operationalized by a 10% cutoff for users with the highest number of treatments, highest costs and/or other criteria depending on the respective health service sector. The insured group investigated received approximately 1.4 million prescriptions, producing costs of 42 million E. High utilizers account for 32% of all prescriptions and 44% of the costs, respectively. At the same time, the age groups with the highest prescription rates do not cause the highest costs: So the relationship between age and prescription drug expenses as well as between age and prescription rates does not display an arithmetically increasing pattern. Within the timeframe investigated 26,000 hospital treatments were accounted for by 21.75% of the elderly under research. In total, they caused expenses of 88 million E. High utilization in the hospital sector was operationalized by four criteria. Sex- and age-specific analysis of high utilization of hospital treatment revealed that the four different criteria apply to different insured groups. In summary, the high utilization of healthcare services appears to be a multidimensional phenomenon.
