Kampo Risk Management Based on a Survey on Incident and Accident Cases at Specialized Kampo Medicine Facilities / 日本東洋医学雑誌

ABSTRACT

The Medical Safety Committee has conducted various activities for patient safety in Japanese traditional Kampo medicines. In this study, we conducted a questionnaire survey to promote the prevention of medical accidents and their recurrence. We received responses from 15 of 19 facilities specializing in Kampo medicine and collected a total of 247 incident and accident cases in the field of Kampo medicine. Cases of side effects included interstitial pneumonia caused by Kampo prescriptions containing Scutellariae Radix, aconite poisoning, and licorice-induced pseudoaldosteronism. Furthermore, we also collected decoction-specific cases, which are unique to facilities specializing in Kampo medicine, for the first time. From the results, we included the following seven points for risk management in the field of Kampo medicine 1) insufficient recognition to the side effects of Kampo medicines, 2) misunderstanding of the dosages of Kampo products, 3) errors due to similarities in Kampo formulas and crude drug names, 4) preconception of frequently used Kampo prescriptions, 5) contamination in the decoctions, 6) errors related to crude drug items and their dosages that are frequently added or subtracted, 7) errors in hospital wards.
