Background: Length of stay (LOS) in patients with ST-segment elevation myocardial infarction (STEMI) is directly associated with financial pressure and medical efficiency. This study aimed to determine impact of LOS on short-term outcomes and associated factors of LOS in patients with ST-segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI).
Methods: A total of 3615 patients with STEMI after PPCI in the China Acute Myocardial Infarction registry were included in the analysis. Predictors of prolonged LOS were analyzed by multivariate logistic regression model with generalized estimating equation. The impact of LOS on 30-day clinical outcomes was assessed.
Results: The median LOS was 9 (7, 12) days. Patients with a longer LOS (> 7 days) were older, more often in lower-level hospitals, had more periprocedural complications and hospitalization expense. Fourteen variables, such as weekend admission and lower-level hospitals, were identified as independent associated factors of prolonged LOS. There were no significant difference in 30-day major adverse cardiac and cerebrovascular events (MACCE), readmission, and functional status between patients with LOS≤ 7d and LOS> 7d after multivariate adjustment and propensity score matching. However, patients who discharged over one week had better medication adherence (adjusted odds ratio: 0.817, 95% confidence interval: 0.687– 0.971, P=0.022). Significant interaction was observed in medication use between gender and LOS (Pinteraction=0.038).
Conclusion: Patients with STEMI undergoing PPCI experienced a relatively long LOS in China, which resulted in more medical expenses but no improvement on 30-day MACCE, readmission, and functional recovery. Poor 30-day medication adherence with short LOS reflects unsatisfying transition of management from hospital to community. More efforts are needed to reduce LOS safely and improve the efficiency of medical care.
