Oncologist and primary care provider attitudes towards shared care in patients with cancer with chronic medical comorbidities.

Abstract

35 Background: Medical comorbidities pose challenges to the delivery of quality cancer care. Underserved cancer patients have the highest burden of chronic comorbidities, with increased risk for worse outcomes. Their health outcomes and care transitions might be improved by enhancing collaboration between oncologists and primary care providers (PCPs). Methods: This is a cross-sectional study of oncologists and PCPs in a large public safety-net hospital system in Houston, TX. Providers completed electronic surveys assessing demographics, attitudes, and satisfaction regarding the shared care of cancer patients with chronic comorbidities. Results: Eighteen oncologists (39% minority, 72% female) and 25 PCPs (23% minority, 77% female) completed the surveys. Independent samples t-tests revealed both oncologists and PCPs reported moderate levels of interprofessional collaboration, felt that existing processes to facilitate coordination of care were inadequate, and expressed moderate levels of dissatisfaction with the management of cancer patients with comorbidities within HHS (all p-values = n.s.). However, their attitudes toward care coordination differed significantly depending on the nature and timing of the care being provided. With regard to side effect management during cancer-directed therapy, 81% of PCPs preferred to co-manage side effects with oncologists, but 100% of oncologists preferred to be responsible for this activity (χ2= 23.08, p <.001). With regard to management of late-effects of cancer treatment, 40% of oncologists were either interested in co-managing late effects with PCPs or having PCPs be solely responsible for this activity. Conversely, 86% of PCPs preferred to co-manage late effects with oncologists (χ2= 26.74, p <.001). For cancer surveillance, oncologists and PCPs expressed interest in sharing responsibility depending on the patient’s risk for recurrence (χ2= 1.62, p =.30). Conclusions: Oncologists and PCPs were similarly dissatisfied with comorbidity management in cancer patients, but differed in their attitudes towards care coordination. Oncologists were more resistant to sharing responsibilities of toxicities during and after treatment. They were more accepting of PCPs assuming follow-up care for lower-risk patients. Further investigation is needed to determine specific areas of care coordination, barriers to provider collaboration, and knowledge and processes for effective shared care.
