BackgroundThe integrated care system Gesundes Kinzigtal (ICSGK), one of the most comprehensive population-based ICS in Germany, started its work nearly 9 years ago. The ICSGK is pursuing the Triple Aim: improving the health of the population, improving the individual's experience of care, and at the same time reducing the per capita costs of care.ObjectivesTo evaluate the impact of the ICSGK on the Triple Aim.Materials And MethodsThe ICSGK is being evaluated externally and internally via a mix of diverse quantitative and qualitative methods. This paper presents selected results for each Triple Aim dimension.Results And ConclusionsRegarding population health, most of the quality indicators examined by the external scientific evaluation show positive development. For example, the prevalence of patients with fractures among all insurants with osteoporosis is presented. In 2011, this prevalence was approximately 26 % in the "Kinzigtal" population (aged ≥ 20 years old) in comparison to 33 % in the control group. As far as patient experience is concerned, to the question "Would you recommend becoming a member of Gesundes Kinzigtal to your friends or relatives?" 92.1 % of those questioned answered "Yes, for sure" or "Yes, probably." Twenty-four percent of those questioned further stated that they would now live "more healthy" than before enrolment in the ICSGK. In the subgroup of questioned insurants who had objective agreements with their doctors 45.4 % answered in this way. On the subject of cost-effectiveness, for both participating socil health insurance schemes, cost savings relative to the costs normally expected for the ICSGK population concerned are observed every year. In the seventh intervention year (2012) the total is 4.56 million Euros for the AOK Baden-Württemberg (BW), which is a contribution margin of 146 Euros per insurant for the 31.156 insurants concerned (LKK BW = 322 Euros per insurant relative to cost savings). The results presented in this paper indicate positive effects in all three Triple Aim dimensions. Further longitudinal studies are recommended to validate those first results together with a detailed analysis to obtain in-depth insights into the specific influence of subcomponents of the total intervention.
