Background and objective Multiple comorbidities may contribute to high readmission rates post-transplant procedures. In this study, we aimed to assess the rates and factors associated with hospital readmissions for dyspeptic symptoms among transplant patients. Methods This was a retrospective analysis of adult patients who underwent solid organ transplants at our institution. Pregnant patients or those patients with preexisting gastroparesis were excluded from the study. Readmissions associated with the International Classification of Diseases (ICD) codes for nausea/vomiting, weight loss, failure to thrive, abdominal pain, and/or bloating were included. Factors associated with 30-day and frequent readmissions (two or more) were explored. Results A total of 931 patients with solid organ transplants were included; 54% had undergone kidney transplants while 34% were liver transplants. Of note, 30% were readmitted within the first 30 days after discharge following transplant while 32.3% had frequent readmissions. A post-transplant upper endoscopy (EGD) was performed in 34% with food residue discovered in 19% suggesting gastroparesis. However, since only 22% of these patients had a gastric emptying study, only 6% were formally diagnosed with gastroparesis, which was independently associated with both 30-day [odds ratios (OR): 2.58, 95% confidence intervals (CI): 1.42-4.69] and frequent readmissions (OR: 6.71, 95% CI: 3.45-13.10). The presence of pre-transplant diabetes (35%) was significantly associated with a diagnosis of gastroparesis following transplant (OR: 5.17, 95% CI: 2.79-9.57). The use of belatacept (OR: 0.63, 95% CI: 0.42-0.94, p=0.023) was associated with a decrease in the odds of 30-day readmissions. Conclusion A significant number of patients were readmitted due to dyspeptic symptoms after solid organ transplants. Diabetes and gastroparesis were significantly associated with higher odds of readmissions while the use of belatacept appeared to be a protective factor.
