PurposeTo compare the medication history error rate of the emergency department (ED) pharmacy technician with that of nursing staff and to describe the workflow environment.MethodsFifty medication histories performed by an ED nurse followed by the pharmacy technician were evaluated for discrepancies (RN-PT group). A separate 50 medication histories performed by the pharmacy technician and observed with necessary intervention by the ED pharmacist were evaluated for discrepancies (PT-RPh group). Discrepancies were totaled and categorized by type of error and therapeutic category of the medication. The workflow description was obtained by observation and staff interview.ResultsA total of 474 medications in the RN-PT group and 521 in the PT-RPh group were evaluated. Nurses made at least one error in all 50 medication histories (100%), compared to 18 medication histories for the pharmacy technician (36%). In the RN-PT group, 408 medications had at least one error, corresponding to an accuracy rate of 14% for nurses. In the PT-RPh group, 30 medications had an error, corresponding to an accuracy rate of 94.4% for the pharmacy technician (P < 0.0001). The most common error made by nurses was a missing medication (n = 109), while the most common error for the pharmacy technician was a wrong medication frequency (n = 19). The most common drug class with documented errors for ED nurses was cardiovascular medications (n = 100), while the pharmacy technician made the most errors in gastrointestinal medications (n = 11).ConclusionMedication histories obtained by the pharmacy technician were significantly more accurate than those obtained by nurses in the emergency department.
