Multicenter Study
Use of critical pathways to improve the care of patients with acute myocardial infarction.
While critical pathways have become a popular strategy to improve the quality of care, their effectiveness is not well defined. The objective of this study was to investigate the effect of a critical pathway on processes of care and outcomes for Medicare patients admitted with acute myocardial infarction. ⋯ Hospitals that instituted critical pathways did not have increased use of proven medical therapies, shorter lengths of stay, or reductions in mortality compared with other hospitals that commonly used alternative approaches to quality improvement among Medicare patients with myocardial infarction.
