Abstract

Background and study aims Current guidelines conditionally recommend performing early colonoscopy (EC) (< 24 hours) in patients admitted with acute lower gastrointestinal bleeding (LGIB). It remains unclear whether this practice is implemented widely. Therefore, we used the Nationwide Inpatient Sample to investigate trends for timing of colonoscopy in patients admitted with acute LGIB. We also assessed trend of hospitalization and mortality in patients with LGIB.

Patients and methods Adult patients with LGIB admitted from 2005 to 2014 were examined. ICD-9-CM codes were used to extract LGIB discharges. Trends were assessed using Cochrane-Armitage test. Factors associated with mortality, cost of hospitalization, and length of stay (LOS) were assessed by multivariable mixed-effects and exact-matched logistic, linear regression, and accelerated-failure time models, respectively.

Results A total of 814,647 patients with LGIB were included. The most common etiology of LGIB was diverticular bleeding (49 %) and 45 % of patients underwent EC. Over the study period, there was no change in the trend of colonoscopy timing. Although admission with LGIB increased over the study period, the mortality rate decreased for patients undergoing colonoscopy. Independent predictors of mortality were age, surgery (colostomy/colectomy) during admission, intensive care unit admission, acute kidney injury, and blood transfusion requirement. Timing of colonoscopy was not associated with mortality benefit. However, cost of hospitalization was $ 1,946 lower and LOS was 1.6 days shorter with EC.

Conclusion Trends in colonoscopy timing in management of LGIB have not changed over the years. EC is associated with lower LOS and cost of hospitalization but it does not appear to improve inpatient mortality.
