Background and Aims: Demand for endoscopy continues to increase, and it is critical to identify factors limiting practice efficiency.
The aims of our study were twofold: to identify major bottlenecks in our workflow, and to quantify differences between scheduled procedure times (SPT) and actual procedure times (APT) at our high-volume academic tertiary care endoscopy center.
Methods: We categorized and quantified reasons for delay to the start of the first case of the day through our electronic medical record. To compare SPT and APT, we collected data on all endoscopies from May 2019 to February 2020 and determined mean time
discrepancies of our ten most frequently performed procedures.
Results: The mean preoperative time was 67 minutes. A median of 27 minutes were spent with nursing for preoperative documentation. 74% of first cases started late, and approximately 10% of inpatient cases rolled over to the next day. The most common factors were patient and gastroenterologist tardiness, causing mean delays of 35 and 22 minutes respectively. 48% of cases went over their SPT. Inpatient esophagogastroduodenoscopy (EGD), colonoscopy, and endoscopic retrograde cholangiopancreatography (ERCP) went a mean of 21.3 (p<0.01), 19.4 (p<0.01), and 15.8 (p<0.01) minutes over their SPT, respectively. Outpatient colonoscopy and ERCP went a
mean of 5.23 (p<0.01) and 19.7 (p<0.01) minutes over their SPT, respectively.
Conclusion: Potential targets to improve inefficiency include patient and GI physician tardiness and reducing nursing preoperative documentation time. Inpatient procedures including EGD, colonoscopy, and ERCP along with outpatient colonoscopy and ERCP were significantly delayed and would benefit from additional scheduled time.
