At the Niigata Pharmacy, there were 3, 402 inquiries about prescriptions during the period from April 2001 to March 2002, and 1, 055 of these inquiries were safety-related, equivalent to 31.0% of all inquiries and 1.60% of all prescriptions. Among these safety-related inquiries, there were 566 adverse effect-related cases (16.6% of all inquiries) and 489 were symptom aggravation-related cases (14.4% of all inquiries). The breakdown of the safety-related inquiries was 30.7% for prescription errors, 46.0% for prescription omissions and 23.3% for pharmacological problems. The frequency of pharmacological problems was significantly higher for adverse effect-related cases as compared with symptom aggravation-related cases (p< 0.0001, X
2-test). On the other hand, symptom aggravation-related cases had a significantly higher frequency of prescription omissions (p< 0.0001, X
2-test) as compared with the adverse effect-related cases. As for the source of the inquiries, 37.7% stemmed from reviews of the patient's drug history, 46.1 % from patient complaints and 16.2% from examination of prescriptions. Among the safety-related cases, the rate for changing prescription content was 81.4%, for which rates were 75.6% for adverse effect-related cases and 88.1% for symptom aggravation-related cases when further broken down. When analyzed, the rate for the symptom aggravation-related cases was significantly higher than that for adverse effect-related cases (p< 0.0001, X
2-test).
Our findings indicate that pharmacists must practice proper risk management to prevent symptom aggravation and adverse effects in patients. Also, to ensure the safety of the patient, pharmacists must examine prescriptions for errors, review the drug history of the patient, and listen to patient complaints.
