Vulnerable populations and the emergency ventral hernia: A retrospective cohort study

Ventral hernias can be repaired electively; however, many circumstances require emergency repair. The association between sociodemographic status and rate of emergency repair are unclear and the Social Vulnerability Index may be a useful tool to better understanding this association. The purpose of this study was to investigate the association between Social Vulnerability Index and emergency ventral hernia repair.

This was a retrospective cohort study using the National Surgical Quality Improvement Program (2012-2018) data for patients at a level 1 trauma center. We included patients who had an open ventral hernia repair. Social Vulnerability Index was based on residential address at the time of surgery. We conducted univariate and bivariate statistics, including χ² and Mann-Whitney U tests to compare high and low social vulnerability.

Our sample had 1,017 patients. Patients who underwent emergency operations were older (P = .025) and had higher Social Vulnerability Index (P = .029). Patients in the high Social Vulnerability Index group were 1.5 times more likely to receive emergency surgery (P = .047). Emergency repair was also associated with increased frequency of nonhome discharge (9% vs 2%, P = .001) and higher mean work relative value unit (15.4 vs 11.9, P < .001).

Patients requiring emergency ventral hernia repair have significantly higher Social Vulnerability Index than those undergoing elective repair. This vulnerable population also has increased cost associated with the repair and higher rates of nonhome discharge. This work provides a foundation for efforts to reach patients in high Social Vulnerability Index environments at an earlier stage to achieve earlier elective repair.
