Gastroparesis can be associated with severe symptoms. Health care utilization for gastroparesis has increased in part due to an increase in hospital admissions. To characterize patients admitted for gastroparesis-related symptoms and determine risk factors associated with 30-day readmissions. The Nationwide Readmission Database (NRD) for the year 2014 was used to identify patients admitted to hospitals using the International Classification of Diseases (ICD)-9 code for gastroparesis as primary diagnosis or as the secondary diagnosis with first diagnosis code of a gastroparesisrelated symptom. Logistic regression was used to determine risk factors associated with 30-day readmission. There were 5268 gastroparesis patients admitted with the average length of stay (LOS) of 5.4±6.6 days. Age averaged 48.9±18.1 years, 73.8% were female individuals, and 31% had diabetes. Inpatient mortality was 0.4%. The overall 30-day readmission rate was 6.2%. Longer LOS [odds ratio (OR)=1.4; 95% confidence interval (CI), 1.0-1.9], younger age, drug abuse (OR=1.6; 95% CI, 1.2-2.2), and marijuana use (OR=1.7; 95% CI, 1.0-2.7) were associated with increased risk of 30-day readmission. Female gender (P=0.083), opioid use (P=0.057), and admission to larger hospital (P=0.070) showed a trend toward higher readmission rates. Older patients, and patients with hypertension and diabetes showed lower rates of readmission. Use of the Nationwide Readmission Database (NRD) allows better understanding of gastroparesis admissions and readmissions. Average hospital stay was 5.4 days with 0.4% mortality rate. Overall 30-day readmission rate was 6.2%. Higher LOS, drug abuse, and marijuana use increased the 30-day readmission rate. Diabetes, hypertension, and older age were associated with lower readmissions.
