BACKGROUND: Admission medication history (AMH) errors frequently cause medication order errors and patient harm. OBJECTIVE: To quantify AMH error reduction achieved when pharmacy staff obtain AMHs before admission medication orders (AMO) are placed. METHODS: This was a three-arm randomised controlled trial of 306 inpatients. In one intervention arm, pharmacists, and in the second intervention arm, pharmacy technicians, obtained initial AMHs prior to admission. They obtained and reconciled medication information from multiple sources. All arms, including the control arm, received usual AMH care, which included variation in several common processes. The primary outcome was severity-weighted mean AMH error score. To detect AMH errors, all patients received reference standard AMHs, which were compared with intervention and control group AMHs. AMH errors and resultant AMO errors were independently identified and rated by ���2 investigators as significant, serious or life threatening. Each error was assigned 1, 4 or 9 points, respectively, to calculate severity-weighted AMH and AMO error scores for each patient. RESULTS: Patient characteristics were similar across arms (mean��SD���age 72��16 years, number of medications 15��7). Analysis was limited to 278 patients (91%) with reference standard AMHs. Mean��SD AMH errors per patient in the usual care, pharmacist and technician arms were 8.0��5.6, 1.4��1.9���and 1.5��2.1, respectively (p<0.0001). Mean��SD���severity-weighted AMH error scores were 23.0��16.1, 4.1��6.8���and 4.1��7.0 per patient, respectively (p<0.0001). These AMH errors led to a mean��SD of 3.2��2.9, 0.6��1.1���and 0.6��1.1 AMO errors per patient, and mean severity-weighted AMO error scores of 6.9��7.2, 1.5��2.9���and 1.2��2.5 per patient, respectively (both p<0.0001). CONCLUSIONS: Pharmacists and technicians reduced AMH errors and resultant AMO errors by over 80%. Future research should examine other sites and patient-centred outcomes.
