The Mayo Clinic Hospital Mortality Reduction Project: Description and Results.

Quality improvement, regulatory, and payer organizations use various definitions of hospital mortality as clinical outcome measures. In this prospective study, the authors evaluated a multicomponent intervention aimed at reducing inpatient mortality in a multistate healthcare delivery system. The project was initiated because of a statistically nonsignificant upward trend in mortality suggested by a six-quarter rise in the observed/expected mortality ratio generated by the Vizient Clinical Data Base and Resource Manager.

Concordance Between Registry and Administrative Data in the Determination of Comorbidity: A Multi-institutional Study.

Objective: To characterize agreement between administrative and registry data in the determination of patient-level comorbidities.

Background: Previous research finds poor agreement between these 2 types of data in the determination of outcomes. We hypothesized that concordance between administrative and registry data would also be poor.

Venous Thromboembolism after Inpatient Surgery in Administrative Data vs NSQIP: A Multi-Institutional Study.

Background: Previous studies have documented significant differences between administrative data and registry data in the determination of postoperative venous thromboembolism (VTE). The goal of this study was to characterize the discordance between administrative and registry data in the determination of postoperative VTE.

Study Design: This study was performed using data from the American College of Surgeons NSQIP merged with administrative data from 8 different hospitals (5 different medical centers) between 2013 and 2015.

Postoperative Myocardial Infarction in Administrative Data vs Clinical Registry: A Multi-Institutional Study.

Background: Previous studies have documented significant differences between administrative data and registry data in the determination of postoperative MI. The goal of this study was to characterize discordance between administrative and registry data in the determination of postoperative myocardial infarction (MI).

Study Design: This study was performed using data from the American College of Surgeons NSQIP merged with administrative data from 8 different hospitals, between 2013 and 2015.

Infectious Surgical Complications are Not Dichotomous: Characterizing Discordance Between Administrative Data and Registry Data.

Objective: To characterize reasons for discordance between administrative data and registry data in the determination of postoperative infectious complications.

Background: Data regarding the occurrence of postoperative surgical complications are identified through either administrative or registry data. Rates of complications vary significantly between these two types of data; the reasons for this are not well-understood.
