Does transport time of out-of-hospital cardiac arrest patients matter? A systematic review and meta-analysis.

Background: Despite increasing evidence for specialized cardiac arrest centers, the impact of transport time on out-of-hospital cardiac arrest (OHCA) patients' outcome remains unclear. We systematically reviewed the prognostic impact of transport time in OHCA patients.

Methods: We searched PubMed, Embase, the Cochrane Library, and Web of Science from inception to May 2016 for studies that had reported the relationship between transport time and outcome in OHCA patients.
