Multicenter Study
Interinstitutional variation in management decisions for treatment of 4 common types of cancer: A multi-institutional cohort study.
When clinical practice is governed by evidence-based guidelines and there is consensus about their validity, practice variation should be minimal. For areas in which evidence gaps exist, greater variation is expected. ⋯ National Cancer Institute and National Comprehensive Cancer Network.
