Why the study?

Regional variations in in-hospital ACS mortality had been reported, but the reasons for these variations were not clearly defined.

Population

79 585 ACS patients across 150 tertiary hospitals in 30 provinces in China

Comparison

Observed vs expected in-hospital mortality across different provinces

Design

National registry and quality improvement project analysis

Implication

Regional ACS mortality variation persists after patient adjustment; leaves open unmeasured care or system factors for targeted investigation.

Structured PICO

P
Population
79,585 acute coronary syndrome (ACS) patients enrolled from 2014 to 2018 in 150 tertiary hospitals from 30 provinces across China

Outcome
In-hospital mortality (observed, expected, and risk-adjusted ratio)hard clinical

Regional variations in in-hospital ACS mortality in China are substantial and only partially explained by differences in patient characteristics, suggesting other factors like quality of care play a significant role.
