In‐hospital mortality in gastroparesis population and its predictors: A United States‐based population study

Abstract

Abstract Background and Aim To determine the United States‐based in‐hospital gastroparesis mortality rate and independent predictors associated with it. Methods A retrospective study was conducted using the deidentified National Inpatient Sample and Healthcare Cost and Utilization Project database between the years 2012 and 2014. The in‐hospital gastroparesis mortality rate was calculated. Patients' demographics, including age, gender, race, comorbid conditions, and hospital characteristics, were examined as potential predictors of mortality. Results The gastroparesis mortality rate was 3.19 per 1000 gastroparesis patients for the years 2012–2014. Caucasians had the highest mortality rate, with odds ratio (OR) = 2.27; 95% confidence interval (CI) 1.52–3.38, and P = 0.0001. Rural hospitals had higher mortality, with OR = 1.51, 95% CI 1.10–2.10, and P = 0.01, whereas urban nonteaching and teaching hospitals showed no statistically significant mortality difference, with OR = 0.83, 95% CI 0.6–1.15, and P = 0.27 and OR = 0.82, 95% CI 0.59–1.15, and P = 0.25, respectively. In hospitals in the south region, mortality was the highest at 65.6%, with OR = 2.05, 95% CI 1.48–2.84, and P < 0.0001. Patients with diabetes mellitus had 39% lower probability in the mortality group. Conclusion Being of advanced age; being White; and being in a rural, southern U.S. hospital were predictors of in‐hospital mortality in gastroparesis patients.
