摘要

Background

Diagnosis-related grouping (DRG) payment has been widely introduced into the management of patients with acute coronary syndrome (ACS) in chest pain centers, but its impact on hospital costs, hospital days, and medical quality in ACS patients, especially with the construction of chest pain centers, has not been fully studied.

Methods

In this study, 12,760 consecutive patients were diagnosed with ACS in the chest pain center of our hospital from 1 January 2015 to 31 June 2023. Through multivariate logistic regression and tendency score matching analysis, we explored the before and after differences in hospitalization costs, hospital days, and quality of ACS during the three key time periods (before the standard construction and implementation of DRG payment, after the construction of the CPC specification and before the implementation of DRG payment, after the standard construction and implementation of DRG payment).

Results

After the implementation of DRG payment, the proportion of hospitalization costs (β = −7950.28, 95% CI −8861.51, −7039.06, p < 0.001), hospitalization days (β = −1.57,95% CI −1.77, −1.36, p < 0.001), and readmission for heart failure ( HF) (OR = 0.53,95% CI 0.43,0.65, p < 0.001) of ACS patients all decreased. At the same time, we also found that the implementation of DRG payment and the standardized construction of CPC played a synergistic effect in the management of ACS patients, which significantly reduced hospitalization costs, hospitalization days and the proportion of readmission for HF in ACS patients (p < 0.001).

Conclusion

DRG payment can reduce hospitalization costs, hospitalization days, and the proportion of HF readmissions in patients with ACS. At the same time, the implementation of DRG payment and the standard construction of CPC have a synergistic effect on the improvement of medical quality of ACS patients. Hospitalization costs, hospitalization days, and the proportion of readmissions for HF were significantly reduced.
