Abstract

Background/aims An effective workflow at the endoscopy unit is important for optimal production. We conducted a time-and-motion study to identify the amount of time that patients spend during the different steps of a regular endoscopy procedure and compared propofol with midazolam sedation. Methods Data from 376 patients were prospectively collected. Durations of the different procedure steps were measured. Correlations between recovery times, age, and dose of sedative were calculated. Multiple regression analysis was performed to evaluate how various factors affect recovery time. Results The use of midazolam resulted in significantly shorter procedure duration for gastroscopy (5.1 vs 8.3 min), shorter endoscopist delay duration for either types of endoscopy (5.9 vs 8.3 min for gastroscopy and 6.7 vs 11.4 min for colonoscopy), shorter endoscopy room duration for gastroscopy (22.2 vs 30.0 min), shorter recovery time for colonoscopy (23.4 vs 27.4 min) and shorter Endoscopy Unit Duration for either type of endoscopy (77.1 vs 101.4 min for gastroscopy and 99.6 vs 123.2 min for colonoscopy). There was a weak correlation between dose of midazolam and recovery time. Conclusions In contrast to other studies, propofol administration leads to more time spent at different steps in the workflow at our unit. Implementing propofol sedation will not improve efficacy if other steps in the workflow are not taken into account.
