Speed and Accuracy of Recording Medication History by Pharmacists in Secondary Emergency Rooms

In Japan, only few hospitals have pharmacists in their secondary emergency rooms to record medication history and provide drug information in real time. In this study, we investigated the benefits of pharmacist intervention in secondary emergency rooms by comparing the time taken by the pharmacists and non-pharmacists in the emergency room to record the medication history in the electronic medical record and the accuracy of its content. The study period was from September 1 to September 30, 2022, and included patients who were transported to our hospital for emergency care between 9:00 and 16:30. We compared the time taken between the patient's arrival until the recording of their medication history and the accuracy of the record by the emergency room pharmacists and non-pharmacists (paramedics or medical clerks). The study included 58 patients whose medication histories were collected by pharmacists, and 11 patients whose histories were collected by non-pharmacists. For pharmacists, the median time to record medication history in the electronic medical record was 12 min, whereas for non-pharmacists, it was 19 min, which was significantly different (p=0.015). The pharmacists accurately recorded the medication history of 98.3% (57/58) of patients, whereas non-pharmacists accurately recorded it for only 54.5% (6/11) of patients, with a significant difference (p<0.01). We observed that in secondary emergency rooms, when pharmacists were responsible for recording the patients' medication histories, it resulted in rapid and accurate sharing of medication history.
