A Comprehensive Set of Coded Chief Complaints for the Emergency Department

Abstract

Objective: To develop a generally applicable set of coded chief complaints for the computerized patient records of emergency departments (EDs). Methods: At an urban teaching ED the chief complaints of more than 50,000 patients were analyzed retrospectively during a 29‐month period (June 1995—October 1997). Applying continuous quality improvement methods, a multidisciplinary team examined the current process documenting the patient's chief complaint. During two prospective periods (November 1997—December 1998; January 1999—June 1999), more than 34,000 chief complaints were analyzed. To reduce free‐text charting practices, a variety of interventions on individual and team level were applied. Quantitative analysis was performed with statistical process control charts, and a qualitative evaluation was performed with a questionnaire. Results: The charting of chief complaint in free‐text format decreased from 23% to 1%. The range among individual ED staff members narrowed from 45% to 9%. During the refinement of the set of coded chief complaints, six infrequently charted items were removed. Five new chief complaints identified by analysis of free‐text entries during the second study period were added. The current set of chief complaints consists of 54 codable and the three original free‐text items. The ED staff members perceived all the interventions beneficial. A poster displaying all available terms as a visual aid, however, had the largest impact on charting the patient's chief complaint in coded format. Conclusions: Applying continuous quality improvement methods, the authors created a clinically developed and applicable set of codable chief complaints that can be easily integrated into a computerized patient record of an ED.
