Analysis on Awareness of Functional Dyspepsia and Rome Criteria Among Japanese Internists by the Self-administered Questionnaires

Background/Aims Functional dyspepsia (FD) is one of the commonest diseases in the field of Internal Medicine. The Japanese Society of Gastroenterology (JSGE) has been enlightening the term and concept of FD. Aim of this survey was to elucidate the understanding status of FD and Rome criteria and attitude toward FD among Japanese internists. Methods Data were collected at the time of lifelong education course for certified members of Japanese Society of Internal Medicine. Self-administered questionnaires were delivered to the medical doctors prior to the lectures. Results Analysis subjects were 1,623 (24-90 years old) internists among 1,660 medical doctors out of 4,264 attendees. The terms related to FD were known in 62.0-68.9% of internists, whereas 95.5% understood chronic gastritis. Internists who had been taking care of FD patients informed them as chronic gastritis (50.0%), FD in Japanese Kanji character (50.8%) and FD in Kanji and Katakana (18.6%). Logistic linear regression analysis revealed that positive factors for the understanding of FD and intensive care for FD patients were practitioner, caring many patients and certified physician by JSGE. Existence of Rome criteria was known in 39.9% of internists, and 31.8% out of them put it to practical use. The certified physician by JSGE was a positive factor for awareness, but not for utilization. Conclusions The results suggest the needs of enlightening the medical term FD in Japan and revision of Rome criteria for routine clinical practice. Precise recognition of FD may enhance efficient patient-based clinical practice.
