The Relationship between Quality and Hospital Case Volume – An Empirical Examination with German Data

This paper examines the effects of hospital case volume on quality of care on the example of intact abdominal aortic aneurysm (AAA) and hip fracture (HIP). We conduct the analysis on patient level with multiple logistic regression analysis. Quality is measured with a binary variable which indicates whether the patient has died in hospital. The results show that patients who are treated in hospitals with a higher case volume have on average a significantly lower probability of death.
