Article Abstract

Introduction: The socioeconomic status has impact on trauma, but, how area deprivation index (ADI) or distressed communities index (DCI), relates to mechanisms of injury (MOI) is unknown.

Methods: All trauma cases in 2021 with 9 or 5-zip codes of living location were included. MOI patterns based on ADI or DCI score was examined. Binary logistic regression was performed to assess the relationship between MOI and neighborhoods with socioeconomic disadvantage.

Result: Overall, 3933 patients for ADI and 4497 patients for DCI metric were included. Greater disadvantage areas determined by ADI or DCI were strongly associated with increased penetrating injuries (both p ​< ​0.001). Assault/abuse mechanisms and vehicular injurie were associated with DCI (both p ​< ​0.001) but not ADI. Direct comparison of ADI versus DCI categorizations showed a weak correlation (R ​= ​0.35, p ​< ​0.001).

Conclusion: There was only a weak correlation between DCI and ADI, with DCI demonstrating greater ability to differentiate injury mechanism patterns and incidence.

Article Synopsis
  • A retrospective cohort study aimed to compare three socioeconomic status (SES) indexes and their association with outcomes after anterior cervical discectomy and fusion (ACDF) or lumbar fusion.
  • The study involved identifying adult patients who underwent these surgeries at a medical center from 2014 to 2020, analyzing their preoperative conditions and outcomes based on SES classifications derived from community-level indexes.
  • Results indicated that while patients from lower SES communities had worse preoperative outcomes, the community-wide SES indexes were ineffective in predicting surgical outcomes post-surgery.

Background: The impact of socioeconomic distress on readmission rates following cardiac surgery has not been studied. We hypothesized that patients living in distressed communities would have a higher 30-day readmission rate after cardiac surgery compared to those living in less distressed communities.

Methods: Patients undergoing isolated coronary artery bypass grafting (CABG) between 2016 and 2023 within a regional collaborative were identified.

Background: Socioeconomic disadvantage has been associated with negative outcomes following total hip arthroplasty (THA) and total knee arthroplasty (TKA). The area deprivation index (ADI) and distressed communities index (DCI) are composite rankings that score socioeconomic status (SES) using patients' home addresses. The purpose of this study was to examine the association of ADI and DCI with outcomes following THA and TKA while controlling for potential confounding covariates.
