Overview

Higher-volume hospitals had lower PTCA adverse events; confirms inverse volume-outcome relationship but leaves causality and current thresholds open.

Structured PICO

How did the practice, patient characteristics, and outcomes of PTCA change in California between 1989 and 1995, and how does hospital volume affect outcomes?

P
Population
Patients undergoing percutaneous transluminal coronary angioplasty (PTCA) or stent placement in California hospitals in 1995 (n=37,118 PTCAs, 3,087 stent placements) compared to 1989 (n=24,883 PTCAs).
I
Intervention
PTCA or stent placement in 1995
C
Comparator
PTCA in 1989; also comparison between high-volume and low-volume hospitals
O
Outcome
In-hospital mortality and incidence of death or emergency bypass surgeryhard clinical

The study demonstrates an increase in PTCA volume, patient complexity, and in-hospital mortality between 1989 and 1995, while confirming an inverse relationship between hospital procedure volume and adverse outcomes.
