The Anatomy of a Hospital System Merger: The Patient Did Not Respond Well to Treatment
研究两家营利性医院连锁的合并案例，发现合并虽统一了电子病历和管理流程，但未能带来可检测的绩效提升，对医疗并购研究有启示。
Abstract Despite the continuing U.S. hospital merger wave, it remains unclear how mergers change, or fail to change, hospital behavior and performance. We open the black box of hospital practices through a megamerger between two for-profit chains. Benchmarking the merger's effects against the acquirer's stated aims, we show they achieved some of their goals, harmonizing electronic medical records and sending managers to target hospitals. Postacquisition managerial processes were similar across the merged chain. However, these interventions failed to drive detectable gains in performance. Our findings demonstrate the importance of organizations for merger research in health care and the economy more generally.
