Background: Patients from low socioeconomic backgrounds have greater rates of morbidity and mortality across disease processes. The Distressed Communities Index identified several socioeconomic components that were used to create a Distressed Communities Index score for every ZIP code, then broken into quintiles from prosperous to distressed. We aimed to explore whether socioeconomic distress as defined by the Distressed Communities Index affects the outcome of complex ventral hernia repair in the elderly population.
Methods: Retrospective analysis was performed using the Abdominal Core Health Collaborative data. Included were adults aged 65+ years undergoing elective complex ventral hernia repair from 2013 to 2021. Primary outcomes were postoperative outcomes and composite hernia recurrence by Distressed Communities Index quintile. The Cox proportional hazards model was used for composite recurrence, and logistic regression was used for postoperative outcomes.
Results: A total of 4,172 patients were included. Patients in distressed communities were more likely to identify as female or racial minority and had greater body mass index and American Society of Anesthesiologists class. Lower Distressed Communities Index quintile was associated with larger hernia (P = .012), open repair (P = .019), and 30-day complication (P = .05). There was no association between time to recurrence and Distressed Communities Index quintile (P = .24). After adjusted analysis, there was no significant difference for readmission, reoperation, recurrence, and complications.
Conclusion: Patients from more distressed communities presented in worse clinical status with larger hernias. This likely contributed to greater rates of open repair and complications. However, when adjusted for these variables, outcomes were similar across Distressed Communities Index quintile. This supports the efficacy of complex hernia repair across socioeconomic classes.
