BACKGROUND: Transplant patients receiving immunosuppressant treatment suffer gastrointestinal symptoms (GIS) limiting their health-related quality of life (HRQOL) and causing dose redíuctions and discontinuations. METHODS: This observational, multicenter, cross-sectional study aims to develop and validate a questionnaire for detecting and quantifying the impact of GIS on the HRQOL of patients with functioning organ transplants. We developed a pilot version of the questionnaire SIGIT-QOL (Impact of Gastrointestinal Symptoms on Quality Of Life) and then evaluated the feasibility, validity, and reliability. We consecutively recruited 274 solid organ transplant patients from 20 hospitals. Sociodemographic and clinical data were collected. Patients completed the SIGIT-QOL and Gastrointestinal Quality of Life Index-GIQLI- questionnaires. RESULTS: Mean age was 52.7 (SD, 7.59) and 181 were male; 43.4% showed an episode of GIS since transplantation (3-12 months before). Of all patients, 95.3% completed the SIGIT-QOL. Mean time of completion was 6.49 minutes. Exploratory factorial analysis identified a 1-dimensional structure (42% of total variance). Internal consistency was high (Cronbach's alpha, 0.889). A significant association was found between the SGITI-QOL and the presence of GIS (P < .01). Finally, correlation coefficients between SIGIT-QOL and GIQLI were moderate-high except for Social Function. CONCLUSION: The brief SIGIT-QOL questionnaire can detect and quantify the GIS and their impact on the HRQOL of solid organ transplant patients.
