This study examines the evidence that a particular quality improvement collaborative that focused on Quality, Efficiency, Safety and Transparency (QUEST) was able to improve hospital performance.
The collaborative included a range of improvement vehicles, such as sharing customized comparative reports, conducting online best practices forums, using 90-day rapid-cycle initiatives to test specific interventions, and conducting face-to-face meetings and quarterly one-on-one coaching sessions to elucidate opportunities.
With these kinds of activities in mind, the objective was to test for the presence of an overall "QUEST effect" via statistical analysis of mortality results that spanned 6 years (2006-2011) for more than 600 acute care hospitals from the Premier alliance.
The existence of a QUEST effect was confirmed from complementary approaches that include comparison of matched samples (collaborative participants against controls) and multivariate analysis.
The study concludes with a discussion of those methods that were plausible reasons for the successes.
本研究检验了一项专注于质量、效率、安全与透明度（QUEST）的特定质量改进合作项目能够提升医院绩效的证据。
该合作项目包括一系列改进手段，如分享定制的对比报告、举办在线最佳实践论坛、利用90天快速循环项目测试特定干预措施，以及召开面对面会议和季度一对一辅导会议以明确改进机会。
考虑到这类活动，目标是通过对来自Premier联盟的600多家急性护理医院6年（2006 - 2011年）的死亡率结果进行统计分析，来检验总体“QUEST效应”是否存在。
通过包括匹配样本比较（合作参与者与对照组）和多变量分析在内的互补方法，证实了QUEST效应的存在。
该研究最后讨论了那些可能是成功原因的方法。
