Improving Mortality Through a Multihospital, Collaborative Quality Improvement Project.

Abstract

Improving hospital mortality is a key focus of quality and safety efforts at both the local and national level. Structured interventions can assist organizations in determining whether interventional efforts have led to sustained improvement. The PARiHS framework (Promoting Action on Research Implementation in Health Services) can assist organizations in implementing research into practice. This study investigates the use of the PARiHS framework in implementing a multihospital quality improvement project aimed at improving observed-to-expected mortality as measured by Vizient's Clinical Data Base (CDB). Structured interventions during the study period included mortality reviews, clinical documentation improvement opportunities, educational webinars, training and support in the use of CDB to explore ongoing opportunities for mortality improvement and quarterly reports to each participating hospital's leadership team on their performance. Data were gathered from an improvement collaborative in the Upper Midwest, which comprised 34 hospitals, of which 17 participated in the intervention. Measurement occurred from Quarter 4 2016 through Quarter 3 2020 and consisted of a preintervention, intervention, and postintervention period. Although both participating and nonparticipating hospitals achieved a significant reduction in their mortality observed-to-expected ratio from the preintervention period through the postintervention period, the participating hospitals achieved a greater reduction in their observed-to-expected mortality ratio ( P < 0.0004). In addition, the participating hospitals achieved a relative 21% improvement in the mortality domain rank of the Vizient Quality & Accountability Study.
