BACKGROUND: General Surgeon Workforce Density (WFD) is used to approximate surgical access. Treatment-incidence ratios (TIR) provide a novel measure of care access. TIR's association with General Surgeon WFD has not been evaluated. STUDY DESIGN: Retrospective cohort study of North Carolina inpatient discharges (2016-2019). The association between county and Hospital Service Area (HSA) TIRs for general surgical diseases was analyzed using adjusted linear and logistic regression. RESULTS: When adjusting for pertinent covariates, county General Surgeon WFD and TIR (-0.0009, 95 % CI -0.028,0.026
p 0.95) and HSA General Surgeon WFD and TIR (0.008, 95 % CI -0.021,0.037
p 0.58) were not statistically significantly associated. The odds of a county 0.91 (95 % CI 0.42,1.97
p 0.82) or HSA (OR 0.93, 95 % CI 0.43,2.04
p 0.86) having a high TIR was not associated with WFD. CONCLUSION: General Surgeon WFD is not associated with disease-specific procedural rates of common surgical conditions at the county or HSA level.
