Physician and practice characteristics influencing tumor board attendance: Results from the provider survey of the Los Angeles Women's Health Study
e17501 Background: Coordination of care has grown in importance with the advent of new modalities of treatment requiring specialized expertise. In cancer care, multidisciplinary approaches have shown improvements in quality of care and patient satisfaction. Tumor boards provide a mechanism for improving coordination of care. We evaluated physician and practice characteristics that predict frequency of tumor board attendance. Methods: This cross-sectional study utilizes data obtained by surveying physicians of a population-based sample of women with incident breast cancer. Physicians were queried regarding tumor board attendance, specialty (medical oncologist [MO], radiation oncologist [RO], surgeon indicating that the hospital at which most breast cancer surgeries are performed has an American College of Surgeons accredited program [ACOSSg] and surgeon without such affiliation [non-ACOSSg]), physician characteristics (gender, race, teaching involvement, patient volume, number of offices, ownership interest), and practice setting (practice type, size, reimbursement). Univariate, bivariate, and multivariate analyses were performed for the dependent variable characterizing provider report of frequency of tumor board meeting attendance. Results: Most surveyed physicians (83%) report attending tumor board weekly (58%) or monthly (25%). Weekly participation was reported by 63%, 92%, 47%, and 32% of MOs, ROs, ACOSSgs, and non-ACOSSgs (p < 0.01). Specialty and higher patient volumes are significant predictors of more frequent attendance, after adjustment for practice size and type. In comparison to the most prevalent specialty category (low volume ACOSSgs), high volume MOs attend more (p = 0.01), and low volume non-ACOSSgs attend less frequently (p = 0.00). Conclusions: Tumor board attendance implies increased participation in multidisciplinary care, but specific subsets of providers are less frequent users. This not only has implications for choosing providers, but also for efforts to increase attendance. Tumor board agendas and formalized institution wide policies could be designed to further engage low frequency attendees as a means to promote multidisciplinary care and improve health outcomes.
