Abstract
Context
Currently most automated methods to identify patient safety occurrences rely on administrative data codes; however, free-text searches of electronic medical records could represent an additional surveillance approach.
Objective
To evaluate a natural language processing search–approach to identify postoperative surgical complications within a comprehensive electronic medical record.
Design, Setting, and Patients
Cross-sectional study involving 2974 patients undergoing inpatient surgical procedures at 6 Veterans Health Administration (VHA) medical centers from 1999 to 2006.
