Care Pathway Effect on In-Hospital Care for ST-Elevation Myocardial Infarction

Abstract

Objectives: To study the care pathway effect on the percentage of patients with ST-elevation myocardial infarction -(STEMI) receiving timely coronary reperfusion and the percentage of STEMI patients receiving optimal secondary prevention.

Methods: A care pathway was implemented by the Collaborative Model for Achieving Breakthrough Improvement. One pre-intervention and 2 post-intervention audits included all adult STEMI patients admitted within 24 h after onset and eligible for reperfusion. Adjusted (hospital random intercepts and controls for transfer and out-of-office admission) differences in composite outcomes were analyzed by a multilevel logistic regression.

Results: Significant improvements in intervals between the first medical contact (FMC) to percutaneous coronary intervention (PCI) and between the door to PCI were shown between post-intervention audit II and post-intervention audit I. Secondary prevention significantly deteriorated at post-intervention audit I but improved significantly between both post-intervention audits. Six out of nine outcomes were significantly poorer in the case of transfer. The interval from FMC to PCI was significantly poorer for patients admitted during out-of-office hours.

Conclusions: After care pathway implementation, composite outcomes improved for in-hospital STEMI care. Collaborative efforts exploited heterogeneity in performance between hospitals. Iterative and incremental care pathway implementation maximized performance improvement.
