Background Large-scale real-world data to evaluate the impact of chest pain centre (CPC) accreditation on acute coronary syndrome (ACS) emergency care in heavy-burden developing countries like China are rare.
Methods This study is a retrospective study based on data from the Hospital Quality Monitoring System (HQMS) database. This study included emergency patients admitted with ACS to hospitals that uploaded clinical data continuously to the database from 2013 to 2016. Propensity score matching was used to compare hospitals with and without CPC accreditation during this period. A longitudinal self-contrast comparison design with mixed-effects models was used to compare management of ACS before and after accreditation.
Results A total of 798 008 patients with ACS from 746 hospitals were included in the analysis. After matching admission date, hospital levels and types and adjusting for possible covariates, patients with ACS admitted to accredited CPCs had lower in-hospital mortality (OR=0.70, 95% CI 0.53 to 0.93), shorter length of stay (LOS; adjusted multiplicative effect=0.89, 95% CI 0.84 to 0.94) and more percutaneous coronary intervention (PCI) procedures (OR=3.53, 95% CI 2.20 to 5.66) than patients admitted in hospitals without applying for CPC accreditation. Furthermore, when compared with the ‘before accreditation’ group only in accredited CPCs, the in-hospital mortality and LOS decreased and the usage of PCI were increased in both ‘accreditation’ (for in-hospital mortality: OR=0.86, 95% CI 0.79 to 0.93; for LOS: 0.94, 95% CI 0.93 to 0.95; for PCI: OR=1.22, 95% CI 1.18 to 1.26) and ‘after accreditation’ groups (for in-hospital mortality: OR=0.90, 95% CI 0.84 to 0.97; for LOS: 0.89, 95% CI 0.89 to 0.90; for PCI: OR=1.36, 95% CI 1.33 to 1.39). The significant benefits of decreased in-hospital mortality, reduced LOS and increased PCI usage were also observed for patients with acute myocardial infarction.
Conclusions CPC accreditation is associated with better management and in-hospital clinical outcomes of patients with ACS. CPC establishment and accreditation should be promoted and implemented in countries with high levels of ACS.
