Emergency department medication and drug interaction evaluation.
The emergency department evaluation had two primary objectives: 1) to determine the accuracy of the oral medication history given at arrival at the emergency department and 2) to determine how often the emergency department physician may prescribe medications which when taken with current medications, may cause a potential drug interaction. Data were collected from 228 emergency department visits of clinic patients 65 years old and older. The average number of medications reported by the patients' medication history was 3.0 +/- 2.3 (range 0-13). The number of medications the patient "forgot" was 1.3 +/- 1.8 (range 0-9). A complete medication history was given by 50.4% of patients. There was an upward trend that correlated with an increased chance for an incomplete medication history as the total number of current medications increased. The rate of a potentially significant drug interaction between a newly prescribed medication in the emergency department and current medications was 3.4% for patients receiving a new medication.
