Disparities in colostomy reversal after Hartmann's procedure for diverticulitis.

BACKGROUND: Hartmann's procedure for diverticulitis is a common procedure, with highly variable rates and timing of colostomy reversal. The aim of this study was to evaluate the impact of race and insurance coverage on reversal within 2 years of Hartmann's procedure for diverticulitis. METHODS: The Healthcare Cost and Utilization Project (HCUP) State Inpatient Database of five states (2007-2010) was queried for patients who had Hartmann's procedure in the setting of diverticulitis. Patients were grouped by race and insurance status, and multivariable adjustment was performed to evaluate rate and timing of colostomy takedown at 2 years. RESULTS: Among 11,019 patients who had Hartmann's procedure for diverticulitis, 6900 (69%) patients had colostomy reversal by 2 years, with a median time to reversal of 19 weeks. Compared to white patients with private insurance, combinations of black race and non-private insurance significantly reduced likelihood of colostomy reversal at 2 years across all combinations. Black patients without insurance had the lowest likelihood of reversal at 2 years (OR 0.27, 95% CI 0.14-0.51, p < 0.001). For patients who had colostomy reversal within 2 years, black patients without insurance had a significant delay in time to reversal (11 weeks, 95% CI 6-16, p < 0.001) compared to white patients with private insurance, and delays persisted across all other groups. CONCLUSIONS: Black patients and those without private insurance experienced significantly lower rates of, and delayed time to, colostomy reversal compared to white patients with private insurance. These disparities must be considered for allocation of resources in marginalized communities.
