OBJECTIVETo establish a clinical database of functional dyspepsia for epidemiological researches and standardizing clinical diagnosis and treatment.

METHODSThe functional dyspepsia database was designed to incorporate the data from in-patients and out-patients with functional dyspepsia treated since July, 2013 and was constructed using Visual Studio. The patient data were collected using a customized case report form designed according to the Roman criteria III and the etiology, symptoms, and treatments of the patients. All the cases deemed ineligible were excluded. The database was displayed on a website and allowed online data entry, case searches and statistical analysis of the clinical parameters.

RESULTS AND CONCLUSIONThe established online database for functional dyspepsia contained data of the general information, clinical symptoms, psychological status, living habits, dietary habits, medical history, examination results, clinical diagnosis, treatment methods and courses, outcomes and data statistics. The database was fully functional and provided complete and standardized data of functional dyspepsia for clinical studies.
