Socioeconomic status does not influence the presentation of patients with inguinal hernia at an urban Canadian teaching hospital

Abstract

Background: Socioeconomic status (SES) has been shown to influence the outcomes of surgical pathologies in areas with unequal access to health care. The purpose of this study was to measure the effect of SES on the urgency for inguinal hernia repair in an area with purported equitable access to health care in the context of a universal health care system. Methods: We included all adult patients who underwent surgical management of an inguinal hernia between 2012 and 2016 at 2 urban academic centres. We measured the SES using the Vancouver Area Neighbourhood Deprivation Index (VANDIX) score. Results: We included 2336 patients: 98 emergency surgery and 294 elective surgery cases. We matched patients without replacement on age, sex and American Society of Anesthesiology score, using optimized propensity score matching at a ratio of 1 case to 3 controls. We found no significant correlation between lower SES and emergency surgical management ( p = 0.122). Secondary analysis assessed the impact of SES on morbidity and length of stay. We found no significant difference in the rate of complications, length of stay and recurrence by SES category. Patients from lower SES brackets had increased odds for readmission (odds ratio 1.979; 95% confidence interval 1.111–4.318). Conclusion: We found no correlation between a low SES and the need for emergency inguinal hernia repair, but found an increased rate of readmission in patients from lower SES brackets. This finding should be further scrutinized through a deeper dive into the barriers to access to nonacute care settings, such as home care.

Evaluation of Regional Geospatial Clusters in Inguinal Hernia Repair

“…This geospatial analysis did not find urbanization and poverty to be significant in comparison between coldspots and hotspots. This is supported by one prior single-institution study that found no relationship between a low socioeconomic status and presentation of an inguinal hernia [26]. In relation to the established risk factors for inguinal hernias, this study finds that age, tobacco, alcohol, and conditions with chronic cough are paradoxically correlated with regions that have reduced inguinal hernia surgeries.…”
