OBJECTIVES This study examines the extent to which Integrated Care Programs lead to an improvement in the quality of patient care. The aim of the study is to carry out a quantitative analysis of differences in quality between patients participating in Disease Management Programs (DMPs) and patients receiving regular care, regardless of health insurance status, program, or region. METHODS The study used data from the representative IMS Disease Analyzer database. It included patients with a confirmed diagnosis of hypertension who started antihypertensive therapy in the period between January 2010 and December 2012. The primary dependent variable of the study was the change in blood pressure after at least six months of antihypertensive treatment. To assess this variable, we determined the proportion of patients with a blood pressure of below 140/90 in the period between day 183 and day 365 after initiation of treatment (index date). In order to eliminate confounding factors, we performed one-to-one matching based on a propensity score. RESULTS CONCLUSIONS It is evident that DMP participants have a significantly better chance of achieving the therapy goal. Thus, it can be established that integrated health care programs have a positive effect on quality.
