The Impact of Primary Care Physicians on the Surgical Presentation and Outcomes of Colorectal Cancer in Vulnerable Populations. Issue 10 (October 2022) - Balan, Naveen
Background: Multiple socioeconomic and clinical factors have been implicated in the health disparities that exist amongst vulnerable populations with colorectal cancer. Efforts have been directed toward addressing these factors to improve outcomes. We evaluate the impact of primary care physicians (PCP) on the surgical presentation and outcomes of colorectal cancer at a safety-net hospital. Methods: A retrospective chart review of 331 patients diagnosed with colorectal adenocarcinoma between 2014 and 2020 at a single-institution urban county medical center. Results: The cohort was predominantly male (59%) and Hispanic (52.1%). Thirty-two percent of patients had a PCP at time of diagnosis. Patients with PCPs compared to those without PCPs had significantly lower rates of acute presentation (perforation or obstruction) (17.0 vs 38.1%, P < .001), higher rates of surgical resection (83.0 vs 70.7%, P = .016), and were less likely to have metastatic disease at presentation (20.4 vs 33.5%, P = .02). Overall, having a PCP also improved probability of survival (HR 1.36, P < .04). Conclusion: Having a PCP at the time of colorectal cancer diagnosis is associated with improved outcomes in a safety-net population, with significant differences in surgical presentation and resection.
