摘要 尽管美国医院合并浪潮仍在持续，但合并如何改变（或未能改变）医院行为与绩效，目前仍不清楚。我们通过两家营利性连锁医院之间的一次大型合并，打开了医院实践的“黑箱”。以收购方既定的目标为基准衡量合并的影响，我们发现他们实现了部分目标，包括统一电子病历、并向目标医院派驻管理人员。收购完成后，合并后连锁体系内的管理流程趋于相似。然而，这些干预措施未能带来可检测到的绩效提升。我们的发现表明，组织对于医疗保健领域以及更广泛经济中的合并研究具有重要意义。
Abstract
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.
