Abstrakt: Introduction: Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States (US), however racial disparities in outcomes persist. We sought to assess the correlation of availability of primary care physicians (PCPs) and racial disparities in CRC-related mortality.
Methods: We studied the correlation between age-adjusted incidence and mortality rates of CRC among all 50 states and the District of Columbia (D.C.) from the Center for Disease Control (CDC) Wide-Ranging Online Data for Epidemiologic Research (WONDER) with the number of actively practicing PCPs in all 50 states and D.C. from the Association of American Medical Colleges (AAMC) State Physician Workforce Data Report. Pearson's coefficient was used to study correlations and the two-sample t test was used for comparing state-level PCP/CRC ratios between the two groups. Statistical analysis was performed using VassarStats.
Results: The mean AAMR per 100,000 population for CRC was significantly higher among AA versus White populations (t = 5.79, p < 0.001). Higher state-wide PCP per CRC case ratio correlated with lower state-wide CRCrelated mortality (r = -0.36, p = 0.011). The mean PCP per CRC case ratio was significantly lower among AA compared to White populations (t = -15.95, p < 0.0001). Higher PCP per CRC case ratio correlated with lower CRC-related mortality among both White (r = -0.64, p < 0.0001) and AA (r = -0.57, p = 0.0002) populations.
Conclusions: These findings suggest that racial disparities in CRC-related mortality may at least in part be related to lower availability of PCPs. Efforts focused on the development of strategies focused on improving access to primary care may help bridge racial disparities in CRC-related outcomes.
