S516 Virtual Visits for Initial Evaluation of Constipation Are Associated With Reduced Outpatient Order Compliance

Introduction: In gastroenterology, telemedicine has emerged as a means for improving patient access to medical care while limiting viral transmission during the pandemic. The purpose of this study was to assess patient order compliance in the virtual vs. in-person setting during the COVID-19 pandemic for the initial evaluation of constipation. Methods: Using natural language processing, we identified outpatient gastroenterology visits (virtual and in-person) for constipation from March 2020 through December 2021. We assessed the number of orders placed for patients during these encounters and determined compliance based on order completion. A generalized linear mixed effects model with fixed effects for visit type and random intercepts for intra-patient correlation was used. A multivariable model was built controlling for age, socioeconomic status, BMI, dementia, stroke, and congestive heart failure. Results: Among 4,930 patients who presented for initial constipation evaluation since the start of the pandemic, 3,515 patients were evaluated in-person and 1,415 patients were evaluated virtually. Comparing order compliance in patients seen during the pandemic, patients seen virtually were 66% less likely to complete orders in comparison to patients seen in-person (p < .001). Patients seen in a pandemic virtual setting were 43% less likely to complete imaging orders (p < 0.001), 78% less likely to complete procedure orders (p < 0.001), and 90% less likely to complete lab orders (p < 0.001) (Table). Increased lab compliance was associated with the highest socioeconomic status ($75,000-$200,000) with patients eight times more likely to complete lab orders (p=0.049) and three times more likely to complete orders overall (p=0.021). Conclusion: Compared with in-person visits, patients seen virtually for their first presentation of constipation were less likely to complete labs, imaging and procedure evaluation ordered. In-person visits were more successful in leading to patient order completion during the pandemic. These findings suggest that virtual visits for constipation, despite convenience, may compromise care delivery; such visits may thus require additional care coordination to achieve compliance with medical recommendations.
