Introduction: Incidence rates of acute diverticulitis (AD) have been increasing rapidly in recent decades. AD has been associated with an increased risk of colorectal cancer (CRC). The majority of guidelines recommend screening with colonoscopy after an episode. Our aim was to identify the compliance rate of colonoscopy for CRC screening, in patients presenting with an episode of AD in the East Orange Veterans Affairs Hospital (EOVA) from 10/01/2015 to 6/30/2019. Methods: We randomly selected 149 patients who were admitted to the EOVA for AD from 10/01/2015 to 6/30/2018 using ICD-10 codes. Patient’s charts were reviewed to look for computed tomography (CT) scan confirmed diverticulitis, complications (abscess, perforation, fistula, obstruction) and post-discharge follow up. Primary outcomes were the compliance rates of post-discharge follow up and colonoscopy. Secondary outcomes were the time interval between discharge and outpatient follow up, and documentation if incomplete. Results: In this study, 91% of the patients were male with a mean age of 62.8 years and BMI of 29.1kg/m2. Sixty-three percent of patients had CT scan confirmed diverticulitis, with 94% occurring in the left colon, and 85.6% occurring without complications. Of those with CT confirmed disease, 69.2% received outpatient follow up and 36.3% had colonoscopy follow up after the acute event. 33% had colonoscopy within 48 months. The mean follow-up interval was 7.4 months. For patients who did not receive colonoscopy, 18% of patients had documentation on why it was not performed, most commonly due to the patient declining. Discussion: Nearly 70% of patients who were admitted to the EOVA for CT confirmed AD had post-discharge follow up within 8 months. However, the colonoscopy compliance rate within 2 years was lower than the national average rate. The reason for non-compliance was not well documented. Further prospective studies will be needed to identify the reason for non-compliance.
