The Association of Race, Ethnicity, and Insurance Status With Outcomes in Hospitalized Patients With Ulcerative Colitis.

Background and Aims

The impact of sociodemographic factors on outcomes in patients with ulcerative colitis (UC) is not well studied. We characterized the association of race/ethnicity and insurance status with procedures, length of stay (LOS), mortality, and cost of care in a cohort of hospitalized patients with UC.

Methods

Data from the National Inpatient Sample from 2016 to 2018 were used. Outcomes were analyzed using generalized estimating equations. All models included age, sex, income quartile, hospital diagnosis, hospital characteristics, and Elixhauser Comorbidity Index as well as the primary predictors.

Results

A total of 34,814 patients were included. Black (adjusted odds ratio [aOR] 0.46, 95% confidence interval [0.39-0.55]) or Hispanic (aOR 0.74, [0.64-0.86]) patients had lower odds of colectomy than White patients. Patients with Medicare (aOR 0.54, [0.48-0.62), Medicaid (aOR 0.51, [0.45-0.58]), or no insurance (aOR 0.42, [0.35-0.50]) had lower odds of colectomy than privately insured patients. Black patients had higher mortality than White patients (aOR 1.38, [1.07-1.78]). Patients with Medicare or Medicaid had 5% ([1.01-1.09]) and 9% longer LOS ([1.05-1.13]), respectively, than privately insured patients, while uninsured patients had a 6% shorter LOS ([0.90-0.97]). Hispanic or Asian/Native American patients had 11% ([1.06-1.15]) and 13% ([1.07-1.20]) higher costs, respectively, than White patients. Uninsured patients had 11% lower hospitalization costs than privately insured patients ([0.85-0.94]).

Conclusion

Hospitalized patients with UC differed significantly in rates of colectomy, mortality, LOS, and costs based on race/ethnicity and insurance status. Further research is needed to understand the cause of these differences and develop targeted solutions to reduce these inequities.
