Evaluating the Impact of Patient Social Deprivation on the Level of Symptom Severity at Carpal Tunnel Syndrome Presentation.

Background: There is a paucity of research examining the impact of social deprivation on the level of symptom severity at presentation, including in common hand conditions like carpal tunnel syndrome. We aimed to determine whether patient deprivation is associated with worse Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE), Physical Function (PF), Pain Interference (PI), and Depression scores. Methods: Patients presenting to an academic hand clinic from December 2016 to December 2018 for a new patient visit for carpal tunnel syndrome completed PROMIS UE, PF, PI, and Depression Computer Adaptive Tests. Bivariate analyses were done to compare patient variables between the least and most deprived thirds, as measured by Area Deprivation Index (ADI), at the state (New York) and national levels. Multivariable linear regression was used to determine whether there was an association between social deprivation and PROMIS UE, PF, PI, and Depression scores. Results: All PROMIS domain scores were significantly worse in the most deprived cohort at the national level (P < .05) but not at the state level (P > .05). In multivariable regression at the national level, ADI values were associated with PROMIS UE (ß = -0.06, P < .01) and PROMIS PI (ß = .05, P < .01) but not PROMIS PF or PROMIS Depression. In multivariable regression at the state level, ADI values were associated with PROMIS UE (ß = -0.79, P = .03) and PROMIS PI (ß = 0.58, P < .05) but not PROMIS PF or PROMIS Depression. Conclusions: Higher levels of social deprivation are associated with worse PROMIS UE and PROMIS PI scores on both the state and national levels when initially seeking care for carpal tunnel syndrome.
