Impact of a quality assurance program on gastrointestinal endoscopy

Abstract

The impact of a quality assurance committee on documentation and use of gastrointestinal endoscopy was assessed. The committee, fulfilling Joint Commission on Accreditation of Healthcare Organizations criteria, performed retrospective (1984-1985) and prospective (1986-1988) reviews of all endoscopies. Criteria were developed from American College of Physicians and American Society for Gastrointestinal Endoscopy guidelines. All reviews of procedures that were questioned were returned to physicians for clarification. After reconsideration of the response, procedures were judged either justified or unjustified. There has been significant improvement in the quality of endoscopy reporting and documentation. The rate of questioned procedures decreased from 21.6% (95% confidence interval (CI), 20.1-23.1) in 1984-1985 to 9.2% (95% CI, 7.9-10.4) (P less than 0.01) in 1988. Improvement in use was reflected in the significant decrease in the rate of unjustified procedures from 8.2% (95% CI, 7.2-9.2) in 1984-1985 to 1.5% (95% CI, 1.0-2.0) (P less than 0.01) in 1988. Most importantly, this process curtailed the previously noted 10% annual increase in the number of endoscopic procedures (P less than 0.01).
