A Quality Improvement Study on Colonoscopy Wait Times in Underinsured Patients Following the COVID-19 Pandemic.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic limited access to colonoscopy. To advance colorectal cancer health equity, we conducted a quality improvement study on colonoscopy wait times in 2019-2023 for underinsured (Medicaid, uninsured) compared to insured patients at an academic medical center providing colonoscopy for surrounding Federally Qualified Health Centers. METHODS: Retrospective chart reviews were performed on adult outpatient colonoscopies in the pre-intervention period (2019-2021). In 2022, an institutional grant funded bilingual patient navigation to reduce colonoscopy wait times. Post-intervention data was collected prospectively from May 2022 to May 2023 in two phases. Multivariable regression analyses were conducted for colonoscopy wait times as a primary outcome. RESULT: Analysis of 3403 screening/surveillance and 1896 diagnostic colonoscopies revealed significantly longer colonoscopy wait times for underinsured compared to insured patients after 2019. For screening/surveillance colonoscopies, wait time differences between underinsured and insured patients in the second post-intervention phase were reduced by 34.21 days (95% CI: 11.07 - 57.35) compared to the post-pandemic period and by 56.36 days (95% CI: 34.16 - 78.55) compared to the first post-intervention phase. For diagnostic colonoscopies, wait time differences in the second post-intervention phase were reduced by 27.57 days (95% CI: 9.96 - 45.19) compared to the post-pandemic period and by 20.40 days (95% CI: 1.02 - 39.77) compared to the first post-intervention phase. CONCLUSION: Colonoscopy wait times were significantly longer for underinsured compared to insured patients following the COVID-19 pandemic. This disparity was partially ameliorated by patient navigation. Monitoring outpatient colonoscopy wait times in underinsured patients is important for advancing health equity.

Predictive Model for Positive Video Capsule Endoscopy in Iron Deficiency Anemia.

BACKGROUND AND AIMS: Bleeding from the gastrointestinal tract can contribute to the development of iron deficiency anemia (IDA) among individuals without another obvious source of bleeding. In order to identify patients most likely to benefit from examination of the small bowel, our aim was to create a risk score for positive video capsule endoscopy (VCE) in IDA utilizing a multicenter collection of studies. METHODS: We performed a retrospective multicenter study utilizing VCE studies performed for an indication of IDA between 1/1/2005 and 7/31/2018. VCE findings were graded based on the P0-P2 grading system. The primary outcome of interest was a positive (P2) VCE. Data were analyzed with Student's t test for continuous variables and the Fisher's exact test for categorical variables. Logistic regression was used to identify independent associations with positive VCE. RESULTS: In total, 765 VCE procedures were included with 355 (46.5%) male subjects and a median age of 63.2 (SD 15.3) years. One hundred ninety studies (24.8%) were positive (P2) for small bowel bleeding. Four variables associated with positive VCE which were incorporated into a point scoring system: (+) 1 for age ≥ 66 years, active smoking and cardiac arrythmia and (-) 1 for preceding hemoglobin level ≥ 8.5. The risk probabilities for positive VCE-assigned scores - 1, 0, 1, and 2 + were 12.3% (95% CI 7.3-17.3%), 20% (14.9-25.1%), 34.8% (28.6-41%), and 39% (30-47.8%). CONCLUSION: In order to improve the diagnostic yield of capsule examinations, risk factors should be applied to clinical decision-making. We created a risk score for positive VCE in IDA, including the risk factors of age, smoking, history of cardiac arrythmia, and preceding hemoglobin level.

Cecal Bascule as a Rare Presentation of Cytomegalovirus Colitis in a Kidney Transplant Recipient.

Cecal bascule is a rare type of volvulus of the colon and requires a mobile cecum and ascending colon, which could be due to congenital or acquired anatomic abnormalities. Inflammatory conditions that cause acute changes in colonic mobility or motility may contribute to development of volvulus, as described in other types of colonic obstruction. Patients with risk factors for a mobile proximal colon presenting with obstructive symptoms should undergo prompt diagnostic evaluation for volvulus to allow for timely intervention. We report an unusual case of invasive cytomegalovirus colitis presenting as cecal bascule in a kidney transplant recipient.
