Background Echocardiography in the setting of resuscitation can provide information as to the cause of the cardiac arrest, as well as indicators of futility. This systematic review and meta-analysis were performed to determine the value of point-of-care ultrasonography (PoCUS) in the assessment of survival for adult patients with cardiac arrest. Methods This meta-analysis was performed in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, EMBASE, Web of Science, Cochrane have been searched from databases inception until March 2 nd 2021. The search was limited to adult patients with cardiac arrest and without publication dates or country restrictions. Papers were chosen if they met the required criteria relating to the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of this diagnostic technique concerning resuscitation outcomes. Results This systematic review identified 20 studies. Overall, for survival to hospital discharge, PoCUS was 6.2% sensitivity (95% confidence interval [CI] 4.7–8.0%) and 2.1% specific (95% CI 0.8–4.2%). PoCUS sensitivity and specificity for return of spontaneous circulation were 23.8% (95% CI 21.4–26.4%) and 50.7% (95% CI 45.8–55.7%) respectively, and for survival to admission 13.8% (95% CI 12.2–15.5%) and 20.1% (95% CI 16.2–24.3%), respectively. Conclusions The results do not allow unambiguous recommendation of PoCUS as a predictor of resuscitation outcomes and further studies based on a large number of patients with full standardization of operators, their training and procedures performed were necessary.
