The Use of Rapid Response Teams to Reduce Failure to Rescue Events: A Systematic Review.

ABSTRACT

OBJECTIVE: The aim of this systematic review was to synthesize the evidence on the impact of rapid response teams (RRTs) on failure to rescue events. METHODS: Systematic searches were conducted using CINAHL, MEDLINE, PsychINFO, and Cochrane, for articles published from 2008 to 2018. English-language, peer-reviewed articles reporting the impact of RRTs on failure to rescue events, including hospital mortality and in-hospital cardiac arrest events, were included. For selected articles, the authors abstracted information, with the study designed to be compliant with Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. RESULTS: Ten articles were identified for inclusion 3 meta-analyses, 3 systematic reviews, and 4 single studies. The systematic reviews and meta-analyses were of moderate-to-high quality, limited by the methodological quality of the included individual studies. The single studies were both observational and investigational in design. Patient outcomes included hospital mortality (8 studies), in-hospital cardiac arrests (9 studies), and intensive care unit (ICU) transfer rates (5 studies). There was variation in the composition of RRTs, and 4 studies conducted subanalyses to examine the effect of physician inclusion on patient outcomes. CONCLUSIONS: There is moderate evidence linking the implementation of RRTs with decreased mortality and non-ICU cardiac arrest rates. Results linking RRT to ICU transfer rates are inconclusive and challenging to interpret. There is some evidence to support the use of physician-led teams, although evaluation of team composition was variable. Lastly, the benefits of RRTs may take a significant period after implementation to be realized, owing to the need for change in safety culture.
