Overview

PCI expansion with radial access and DES was associated with less bleeding but no mortality reduction; leaves open the effect of these changes on survival.

Structured PICO

P
Population
11,241 patients undergoing coronary catheterization and percutaneous coronary intervention (PCI) at 55 urban Chinese hospitals in calendar years 2001, 2006, and 2011.
I
Intervention
Coronary catheterization and percutaneous coronary intervention (PCI) over time (assessed in 2001, 2006, and 2011)
C
Comparator
Temporal comparison (2001 vs. 2006 vs. 2011)
O
Outcome
Patient characteristics, treatment patterns, quality of care, and outcomes associated with coronary catheterization and PCI and changes over time

Despite a massive increase in PCI volume and adoption of modern techniques like radial access and drug-eluting stents in China from 2001 to 2011, significant gaps in quality of care documentation remain.

Limitations

  • Medical records lacked documentation needed to calculate commonly used process metrics including door to balloon times for primary PCI and the prescription of evidence-based medications at discharge
