BACKGROUND

Several studies have demonstrated favorable outcomes for laparoscopic surgery over open surgery for the treatment of diverticular disease. This study was designed to analyze the relationship between race, socioeconomic status and the use of laparoscopy to address diverticulitis.

METHODS

A retrospective analysis of 53,054 diverticulitis admissions was performed using data from the 2009-2013 National Inpatient Sample (NIS). The primary outcome was the use of laparoscopic versus open colectomy. Bivariate analysis and multivariable logistic regression were used to determine the raw and adjusted odds by race, insurance status, and median household income.

RESULTS

Overall, 41.6% of colectomies involved the use of laparoscopy. Black patients were 19% less likely than White patients to undergo laparoscopic surgery. Hispanic patients were no more or less likely to undergo laparoscopic colectomy. Lacking private insurance was a strong predictor of undergoing open surgery. Lower income patients were 33% less likely to receive minimally invasive colectomies.

CONCLUSIONS

These results demonstrate disparities in surgical treatment. Further research is warranted to understand and ameliorate treatment differences which can contribute to outcome disparities.
