Informing best practice for conducting morbidity and mortality reviews: A literature review

Objective. Preventable hospital mortality is a critical public health issue, particularly when mortalities are associated with events that are preventable. Mortality and morbidity reviews (MMRs) provide a rigorous, systematic, open, collaborative and transparent review process for clinicians to examine areas of improvement. The aim of the present review was to explore the evidence for best practice when conducting MMRs. Methods. Searches of published and grey literature from 2009 to February 2016 were conducted. This period was selected to update a previous review. Inclusion and exclusion criteria was established a priori and based on the Population-Intervention-Comparison-Outcome (PICO) framework. Specific search terms were generated and used to identify relevant articles, with reference lists and citing articles also screened for inclusions. Titles and abstracts were screened and duplicates removed. Study details regarding setting, study design, reported outcomes, tool type, clinicians present and the timing of MMRs were extracted and summarised. Results. After screening, 31 documents were included in the present review: 20 peer-reviewed articles and 11 items from the grey literature. Specific outcomes reported included mortality rates, satisfaction, education, cost and quality of care. The most common features of MMRs included timing, leadership, attendees, case presentation format, terms of reference, agenda and governance. Conclusions. MMRs decrease gross mortality rates and are effective in identifying and engaging clinicians in system improvements. MMRs should not focus on the actions of individuals, rather on education and/or quality improvement. MMRsshould consist of a multidisciplinary team following a structured presentation format with an analysis of error process including actions to be followed-up. Further, it is possible for a single standardisedMMRto be implemented hospital wide.
