The emergency department assessment of chest pain score-accelerated diagnostic protocol (EDACS-ADP) are commonly used for risk stratification in undifferentiated patients with acute chest pain. This systematic review aimed to investigate EDACS-ADP for risk stratification of emergency department (ED) patients with chest pain. The PubMed, Web of Science, Medline, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases were searched for related studies without restrictions on the publication year. The Quality Assessment of Diagnostic Accuracy Studies 2 tool was used to assess the risk of bias, and Stata 16.0 was used to determine the combined sensitivity, specificity, positive diagnostic likelihood ratio (DLR), and negative DLR. Twelve studies comprising 14 290 patients were identified. Of these, 7537 (52.74%) patients were considered low risk, and 67 (0.89%) had major adverse cardiovascular events (MACE), including myocardial infarction, stroke, and cardiovascular death within 30 days of the patients' ED presentation. EDACS-ADP showed a combined sensitivity of 0.97 (95% confidence interval [CI]: 0.95-0.99); specificity, 0.58 (0.53-0.63); positive DLR, 2.34 (2.08-2.63); negative DLR, 0.04 (0.02-0.09); diagnostic odds ratio, 53.11 (26.45-106.63); and summary receiver operating characteristic area under the curve, 0.83 (0.79-0.86). Despite the large statistical heterogeneity of the results, EDACS-ADP identified a considerable number of low-risk patients for early discharge, with a specificity >50% and an incidence of MACE within 30-days of patients' ED presentation <1%. Thus, it is a useful tool with a potential for clinical application.
