Key result
Hospital accreditation linked to ~15% lower 30-day AMI mortality compared to nonaccredited centers.
Why the study?
Hospital accreditation programs improve hospital structure, but research results on improving patient clinical outcomes have been mixed.
Does inpatient care at an accredited hospital reduce 30-day mortality, 30-day readmission, and length of stay in patients with acute myocardial infarction compared to nonaccredited hospitals?
Observational (n=80,262)
Yes

Hospital accreditation is associated with lower 30-day mortality for acute myocardial infarction patients, though it does not appear to improve 30-day readmission rates or reduce length of stay.
Accredited hospitals were associated with lower AMI 30-day mortality; leaves open effects on readmissions, length of stay, and need for prospective trials.
Hospital accreditation programs are used worldwide to improve the quality of care and improve patient safety. It is of great help in improving the structure of hospitals, but there are mixed research results on improving the clinical outcome of patients. The purpose of this study was to compare the levels of core clinical outcome indicators after receiving inpatient services from accredited and nonaccredited hospitals in patients with acute myocardial infarction (AMI). For all patients with AMI admitted to general hospitals in Korea from 2010 to 2017, their 30-day mortality and readmissions and length of stay were compared according to accreditation status. In addition, through a multivariate model that controls various patients' and hospitals' factors, the differences in those indicators were analyzed more accurately. The 30-day mortality of patients admitted to accredited hospitals was statistically significantly lower than that of patients admitted to nonaccredited hospitals. However, for 30-day readmission and length of stay, accreditation did not appear to yield more desirable results. This study shows that when evaluating the clinical impact of hospital accreditation programs, not only the mortality but also various clinical indicators need to be included, and a more comprehensive review is needed.

Lee et al. (2021) conducted an observational in Acute myocardial infarction (AMI) (n=80,262). Admission to an accredited hospital vs. Admission to a nonaccredited hospital was evaluated on 30-day mortality (OR 0.845). Admission to an accredited hospital was associated with a significantly lower 30-day mortality rate for acute myocardial infarction patients compared to nonaccredited hospitals (1.51% vs. 3.29%, adjusted OR 0.845).
