Background: Surgical deserts (SDs) are defined as the geographic maldistribution of general surgeons of six or less per 100,000 population in underserved/rural counties. Disparities have been reported in breast cancer outcomes; however, the effect of SDs remains unknown. We sought to examine the effect of SDs on breast reconstruction (BR) after mastectomy and the differences between patients in both the cohorts.

Methods: Using the Nationwide Inpatient Sample database years 2007-2011, we identified International Classification of Diseases 9th edition codes for breast cancer, mastectomy, and BR in California. SDs were identified using the American College of Surgeons Health Policy Research Institute workforce atlas. Data included patient demographics and socioeconomic status, and the primary outcome was the rates of BR.

Results: A total of 9325 mastectomy patients, with or without BR, were identified. Of this, 12.8% patients were in SDs, whereas 87.2% patients were in nonsurgical deserts (NSDs). Overall, 35.8% of patients received BR, whereas 64.2% did not. Of the patients in SDs, only 14% received BR, whereas in NSDs, 39% received BR. On multivariate analysis, SD patients were significantly less likely to receive BR than NSD patients (odds ratio [95% confidence interval], 0.29 [0.24-0.35]; P < 0.001). SDs had higher rates of low household income, Medicare insurance, and comorbidities. NSDs had higher rates of high household income, Health Maintenance Organization/private insurance, and lower rates of comorbidities.

Conclusions: Patients in SDs are significantly less likely to receive BR. This disparity may be magnified because of differences in demographics and income levels, and decreased access to reconstructive surgeons. Interventions aimed at decreasing disparities caused by SDs are needed. (C) 2017 Elsevier Inc. All rights reserved.
