Abstract
PURPOSE: The purpose of this study was to establish the impact of area deprivation index (ADI) on treatment timelines of patients with cubital tunnel syndrome (CuTS). We hypothesize that increased social deprivation will correlate with increased time between care milestones from presentation to surgery. METHODS: This is a retrospective study of patients diagnosed with CuTS who underwent surgical intervention at a single academic institution. Variables including age, sex, body mass index, ADI, electrodiagnostic (EDX) severity classification, and time elapsed between treatment milestones were obtained. Treatment milestones included time elapsed between initial presentation to hand surgery and EDX studies, and surgery. Analysis included univariate χ(2) tests and analysis of variance, as well as multivariate linear and logistic regressions. RESULTS: Six hundred and fifty-three patients were divided by ADI national percentiles from the least to most deprived tertiles. Univariate analysis found no differences in care timelines across ADI tertiles. Multivariate analysis revealed a nonsignificant trend toward higher ADI predicting longer time from presentation to surgery. Moderate EDX rating correlated with increased time from presentation to surgery. Mild EDX ratings correlate with increased time from EDX studies to surgery. Age was a significant predictor of decreased time between initial presentation and surgery and between EDX and surgery. Completion of EDX studies prior to presentation significantly decreased time to surgery. CONCLUSIONS: Social deprivation does not significantly correlate with delays in the treatment timeline for CuTS. Increased age was significantly correlated with shorter treatment timelines, which may reflect differences in physicians' approaches to patients of different ages. Electrodiagnostic testing obtained prior to initial presentation expedited care following presentation to hand clinic. However, this could reflect either an overall delay in care (if EDX were obtained because of a delay from referral to presentation) or truly expedited care. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.
