%X  To conduct a systematic review and meta-analysis evaluating whether CPR guided by real-time feedback or post-event (debriefing-based) feedback improves CPR quality metrics or patient outcomes compared with standard unguided CPR in adult out-of-hospital cardiac arrest (OHCA). In August 2020, we searched PubMed, Embase, CINAHL, and the Cochrane Library for studies published studies after 2010 involving adult OHCA. Key CPR quality outcomes were chest compression depth, rate, and fraction. Critical patient outcomes were any return of spontaneous circulation (ROSC), survival to hospital admission, and survival to hospital discharge. From 9,464 identified records, 61 underwent full-text review, and 8 studies were ultimately included in the meta-analysis (5 examining real-time feedback devices, 3 examining post-event feedback/debriefing). Meta-analysis showed that: Real-time feedback significantly improved compression depth and rate. Post-event feedback significantly improved compression depth and chest compression fraction. No statistically significant improvement in patient outcomes (ROSC, survival to admission, or survival to discharge) was found for either type of feedback. However, absolute differences in survival rates suggested a potentially meaningful clinical benefit. Heterogeneity across studies ranged from low (“might not be important”) to considerable. Both real-time and post-event feedback improve specific aspects of CPR quality. Optimal CPR performance is likely achieved by combining the two approaches. Although neither feedback strategy demonstrated statistically significant improvements in patient survival, a clinically relevant effect appears plausible. These findings are based on a small number of studies with overall low to very low certainty of evidence.
