Background: Socioeconomic status and distance from hospital have been shown to be associated with poor surgical outcomes related to acute appendicitis. Indigenous populations experience greater socioeconomic disadvantages and poorer healthcare access than their non-Indigenous counterparts. This study aims to determine whether socioeconomic status and road distance from hospital are predictors of perforated appendicitis. It will also compare surgical outcomes of appendicitis between Indigenous and non-Indigenous populations.
Methods: We performed a 5-year retrospective study of all patients who underwent appendicectomy for acute appendicitis at a large rural referral centre. Patients were identified using the hospital database for theatre events coded as appendicectomy. Regression modelling was used to determine if socioeconomic status and road distance from hospital were associated with perforated appendicitis. The outcomes of appendicitis between Indigenous and non-Indigenous populations were compared.
Results: Seven hundred and twenty-two patients were included in this study. The rate of perforated appendicitis was not significantly impacted by socioeconomic status (OR 0.993, 95% CI 0.98-1.006, P = 0.316) or road distance from hospital (OR = 0.911, 95% CI 0.999-1.001, P = 0.911). Indigenous patients did not have a significantly higher rate of perforation compared to non-Indigenous patients (P = 0.849) despite having overall lower socioeconomic status (P = 0.005) and longer road distance from hospital (P = 0.025).
Conclusion: Lower socioeconomic status and longer road distance from hospital were not associated with an increased risk of perforated appendicitis. Indigenous populations have poorer socioeconomic status and longer road distance to hospital but did not have higher rates of perforated appendicitis.
