Failure-to-Rescue After Acute Myocardial Infarction

Area of Science:

• Cardiology
• Health Services Research
• Quality Improvement

Background:

• Failure-to-Rescue (FTR) is a metric assessing an institution's ability to prevent death in complicated surgical cases.
• Its utility in evaluating care quality for medical conditions like acute myocardial infarction (AMI) is unexplored.

Purpose of the Study:

• To develop and validate a modified Failure-to-Rescue (FTR) metric for analyzing outcomes in acute myocardial infarction (AMI) admissions.
• To assess the metric's ability to reflect hospital quality of care for AMI patients.

Main Methods:

• A split-sample design was used, with 20% of hospitals for definition development, 20% for test characteristic validation, and 60% for out-of-sample validation.
• The study analyzed data from Medicare beneficiaries admitted for AMI between 2009-2011, focusing on 30-day mortality, FTR rates, and in-hospital complications.

Main Results:

• In a 60% out-of-sample validation (234,277 patients, 1142 hospitals), a strong correlation was found between hospital risk-adjusted 30-day mortality and the modified FTR metric (Spearman r=0.89, P<0.0001).
• Hospitals with characteristics like teaching status and advanced cardiac technology showed significantly lower odds of FTR (odds ratio=0.67, P<0.0001).

Conclusions:

• A modified Failure-to-Rescue (FTR) metric can be effectively developed to study the quality of care for acute myocardial infarction (AMI) admissions.
• This metric offers a valuable tool for assessing and improving care quality in cardiovascular medicine.
