The objective of this study was to assess the nature and extent of AEs among cancer patients across inpatient and outpatient settings.<h4>Methods</h4>This was a retrospective cohort study of 400 adult patients selected by stratified random sampling who had breast (n = 128), colorectal (n = 136), or lung cancer (n = 136) treated at a comprehensive cancer center in 2012. Candidate AEs, or injuries due to medical care, were identified by trained nurse reviewers over the course of 1 year from medical records and safety-reporting databases.
