Do hospitals experience safety tipping points as utilization increases and, if so, what are the implications for hospital operations management? We argue that safety tipping points occur when managerial escalation policies are exhausted and workload variability buffers are depleted. Front-line clinical staff is forced to ration resources and, at the same(More)
Financial soundness will become more and more difficult in the future for all types of hospitals. This is particularly relevant for gynaecology and obstetrics departments: while some disciplines can expect higher demand due to demographic changes and progress in medicine and medical technology, the inpatient sector for gynaecology and obstetrics is likely(More)
The correct definition of the product market and of the geographic market is a prerequisite for assessing market structures in antitrust cases. For hospital markets, both dimensions are controversially discussed in the literature. Using data for the German hospital market we aim at elaborating the need for differentiating the product market and at(More)
PURPOSE Hospital managers are confronted with decisions that have to account for multiple objectives, which may be in conflict with regard to efficiency and quality of care. In empirical studies occupancy and staffing ratios as well as in-hospital mortality are frequently used measures for efficiency and quality-of-care, respectively. Efficiency and quality(More)
For decades, there is an ongoing discussion about the quality of hospital care leading i.a. to the introduction of minimum volume standards in various countries. In this paper, we analyze the volume-outcome relationship for patients with intact abdominal aortic aneurysm and hip fracture. We define hypothetical minimum volume standards in both conditions and(More)

A number of recent empirical studies document signifi cant eff ects of in-patient care quality indicators on the choice of hospital. These studies use either objective quality indicators based on quantitative fi gures, or if subjective reputation scores are used, scores based on the opinion of hospital market insiders. We contribute to the current debate by(More)
OBJECTIVE To examine the causal effect of a hospital's experience with treating hip fractures (volume) on patient treatment outcomes. DATA SOURCES We use a full sample of administrative data from German hospitals for 2007. The data provide detailed information on patients and hospitals. We also reference the hospitals' addresses and the zip codes of(More)
Remuneration rates of German nursing homes are prospectively negotiated between long-term care insurance (LTCI) and social assistance on the one side and nursing homes on the other. They differ considerably across regions while there is no evidence for substantial differences in care provision. This article explains the differences in the remuneration rates(More)
This paper examines the eff ects 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(More)
