Predicting Colonoscopy Time: A Quality Improvement Initiative

다국어 초록 (Multilingual Abstract)

Background/Aims: There is lack of consensus on the optimal time allotted for colonoscopy, which increases patient wait times. Ouraim was to identify and quantify the individual pre-procedural factors that determine the total procedure time (TPT) of colonoscopy.
Methods: This retrospective study involved 4,494 subjects, undergoing outpatient colonoscopy. Effects of age, sex, body mass index,abdominal surgery history, procedure indication (screening, surveillance, or diagnostic), procedure session (morning or afternoon),and endoscopist’s experience (fellow or attending) on TPT were evaluated using multiple regression analysis. A p<0.05 was consideredsignificant.
Results: A total of 1,239 subjects satisfied the inclusion/exclusion criteria. Women, older individuals, and those with a history ofabdominal surgery were found to have a shorter TPT (p>0.05) as did afternoon session colonoscopies (p=0.004). Less experiencedendoscopists had longer TPTs (p>0.05). Screening (p=0.01) and surveillance (p=0.008) colonoscopies had a longer TPT than diagnosticprocedures. Overall, the F-value of the regression model was 0.0009.
Conclusions: The indication for colonoscopy and the time of day have statistically significant associations with TPT. These results willhelp in streamlining workflow, reduce wait time, and improve patient satisfaction.
