Objectives : The purpose of this study was to develop, implement, and assess an estimation procedure for preventing adverse drug reaction by subjective symptoms(complaints)of patients. This time, we focused and studied on drug-induced gastrointestinal system disorders. Methods : We have built a database for CARPIS (Case Reports of Adverse Drug Reaction and Poisoning Information System) since 1987. We studied 224 cases of drug-induced Gastrointestinal System Disorders (stomach or colon disorders : 148,esophagus disorders : 31,pancreas disorders : 45) cumulated in the CARPIS database. The evaluation scores were created based on the subjective symptoms and backgrounds of the patients. We estimated 224 cases using these evaluation scores. Results : We could estimate 137 cases (92.6%) in 148 cases to be stomach or colon disorders by the use of these evaluation scores. The validity of this evaluation scores was estimated to be as follows; Sensitivity=92.6%, Specificity=95.0% and Predictive Value of Positive Test (PVP)=96.5%. The positive likelihood ratio (LR) was 18.5 and negative likelihood ratio was 0.08. On the other hand, in the case of esophagus disorders, PVP was 84.8% and LR was 18.1. In the case of pancreas disorders, PVP was 90.7% and LR was 21.7. Conclusions : In this study, PVP and LR values were good. We thought that these evaluation scores could pick up the drug-induced gastrointestinal system disorders efficiently. We reported previously the evaluation scores about drug-induced liver disorders, extra-pyramidal symptoms, leukopenia and eruption before. In order to apply these evaluation scores onto the clinical practice, we prepared an evaluation form for subjective symptoms and backgrounds of the patients with adverse drug reactions. As a result, the adverse reactions symptoms of each one defined more.
