A Global Overview of Acute Coronary Syndrome Registries: A Systematic Review

Abstract

The present study was conducted with the aim of identifying, and summarizing the characteristics of ACS registries at national, multinational and international levels. Literature was searched using keywords in the title and/or abstract without any time limit ending in March, 2021. After excluding duplicates, 2 reviewers independently reviewed the titles and/or abstracts and full text for inclusion. Each reviewer independently extracted the characteristics of the registries from included papers. Finally, the extracted characteristics were confirmed by a second reviewer. Out of the 1309 papers included, 71 ACS registries were identified (including 60 national and 11 multinational and international registries). Most national registries were being used in Europe. Most registries focused on measuring quality. In more than half of the registries, all types of ACS patients were enrolled. The diagnostic and drug classification systems were mentioned in eight and five registries, respectively. The design of 55 registries was hospital-based. The ability of computerized audit checks was made for 34 registries. More than half of the registries had patient consent and had a web-based design. In all the ACS registries, patient characteristics, clinical characteristics and treatment characteristics were recorded and post-discharge follow-up information was recorded in 45 registries. In the current situation and given that a limited number of countries in the world have national ACS registries, reviewing the results of this study and modeling the registries implemented in the leading countries can help countries without a registry to design it.
