Guideline-concordant surveillance and follow-up care among low-income patients with breast cancer: The role of primary care medical homes.

Abstract

171 Background: Community Care of North Carolina (CCNC) initiated an innovative medical home (MH) program in the 1990s to improve primary care in Medicaid-insured populations. CCNC has been successful in improving asthma, diabetes, and cardiovascular outcomes, but has not been evaluated in the context of cancer care. We sought to determine whether MH enrollment was associated with guideline-concordant surveillance and follow-up care among breast cancer survivors. Methods: Using state cancer registry records matched to Medicaid claims, we identified women ages 18-64 diagnosed with stage 0, I, or II breast cancer from 2003-2007 and tracked their CCNC enrollment. Using published American Society for Clinical Oncology breast cancer survivorship guidelines to define our outcomes, we employed multivariate logistic regressions to examine correlates of receipt of surveillance mammogram and at least two physical exams within 15 months post-diagnosis. Results: In total, 840 women were included in our sample. Approximately half were enrolled in a CCNC MH during the study period, 38% were enrolled for more than 7 months post-diagnosis. Enrollment in a MH for at least 7 months post-diagnosis was strongly associated with receiving guideline-recommended surveillance mammogram (p<0.01) and at least 2 physical exams (p<0.01) within 15 months post-diagnosis. Conclusions: Results suggest that MH enrollment is associated with higher quality breast cancer survivorship care among women insured by Medicaid. Given the growing population of cancer survivors and increased emphasis on primary care MH, more research is needed to explore how medical homes can enhance and ensure the provision of guideline-recommended care during cancer survivorship.
