e15542 Background: In 2020, colorectal cancer was the second leading cause of cancer death in the United States 1 . In March 2020, the COVID pandemic began which led to widespread disparities in health care, such as surveillance colonoscopies 2 . A Veterans Health Administration large data review revealed completion rates of colonoscopy for high risk individuals, including positive fecal immunochemical test (FIT) to be unchanged pre-pandemic and during the pandemic at 27% vs 26.5% 3 . Another study reports a non-VA population completion rate within 360 days pre-COVID compared to COVID was 53.9% vs 44% 4 . This research sought to analyze data through a retrospective chart review from the Memphis VA Medical Center, the timing of screening colonoscopies after a positive FIT and reasons for delay in obtaining these. Thereby, evaluating effectiveness in completing the procedures and change effected by the COVID pandemic. Methods: A retrospective cohort study designed to detect rates of completed colonoscopy during and before the COVID pandemic after a positive FIT. Records were reviewed of all positive FIT from 2 specified time frames at the Memphis VA to evaluate completion of colonoscopy after a positive FIT. The charts of 157 VA patients with positive FIT during the pandemic were compared to the charts of 115 VA patients with positive FIT pre-pandemic for colonoscopy completion, evaluating both completion rates within 180 days and chart identified reasons for lack of completion. Both community (CITC) and VA procedures for veterans were included. One tailed Fisher’s exact test was applied to calculate the completion rate difference. Results: Overall completion rate of colonoscopy was 46% in the pre-COVID and rose to 56% in the COVID period [p-value < .05 (.0665)]. Percentage of timely completion ( < 180 days) was 26% pre-COVID, compared to 47% during COVID. Percentage of delay ( > 180 days) in pre-Covid was 74%, compared to 53% during COVID. [p-value < .05 (.0004)]. Reasons for delay both pre-COVID and during COVID are listed below. Conclusions: It can be concluded that there is a statistically significant increase in timely colonoscopy completion during the studied COVID period when compared to the pre-COVID period. The total completion rate was higher at our institution than in the literature, likely due to our inclusion of community colonoscopies and our aggressive case management system. A common reason for delay in all groups was delay/lack of referral. This cause for delay should be improved with additional steps in our case management policy. [Table: see text]
