Abstract
BACKGROUND AND AIMS: Patient-reported experience measures (PREMs) assessing the tolerability of endoscopic procedures are scarce. In this study, we designed and validated a PREM to assess tolerability of endoscopy using conscious sedation. METHODS: The patient-reported scale for tolerability of endoscopic procedures (PRO-STEP) consists of questions within 2 domains and is administered to outpatients at discharge from the endoscopy unit. Domain 1 (intraprocedural) consists of 2 questions regarding discomfort/pain and awareness, whereas domain 2 (postprocedural) consists of 4 questions on pain, nausea, distention, and either throat or anal pain. All questions are scored on a Likert scale from 0 to 10. Cronbach's alpha was used to measure internal consistency of the questions. Multivariable logistic regression was performed to assess predictors of higher scores, reported using adjusted odds ratios and confidence intervals. RESULTS: Two hundred fifty-five patients (91 colonoscopy, 73 gastroscopy, and 91 ERCP) were included. Colonoscopy was the least tolerable procedure by recall, with mean intraprocedural awareness and discomfort scores of 5.1 ± 3.8, and 2.6 ± 2.7, respectively. Consistency between intraprocedural awareness and discomfort/pain yielded an acceptable Cronbach's alpha of .71 (95% confidence interval, .62-.78). Higher use of midazolam during colonoscopy was inversely associated with an intraprocedural awareness score of 7 or higher (per additional mg: adjusted odds ratio, .23; 95% confidence interval, .09-.54). CONCLUSIONS: PRO-STEP is a simple PREM that can be administered after multiple endoscopic procedures using conscious sedation. Future work should focus on its performance characteristics in adverse event prediction.
