PURPOSE: To determine the percentage of unintentional prior-to-admission (PTA) medication list discrepancies captured by second-source verification.

METHODS: A prospective, randomized, controlled intervention was conducted on all patients admitted to a large academic medical center with a PTA medication list completed by a pharmacy technician from December 2018 through January 2019. Excluded patients included those admitted as observation status or discharged prior to the time of second-source verification. The following data was collected: patient's medical record number, age, admission date and time, service admitted to, date and time of completed PTA medication list, date and time of second-source verification, type of second-source verification, medication name, dose, route, frequency, formulation, and confidence level of pharmacy technician completing the initial PTA medication list. Second-source verification was conducted on all medications from a patient's PTA medication list after completion by a pharmacy technician.

RESULTS: There were a total of 992 medications from the 200 randomly assigned patients with a completed PTA medication list by a pharmacy technician during the study time frame. Of these medications, 116 (11.7%) contained a discrepancy identified by second-source verification. The most common type of discrepancy was omission (67%) followed by dosing, frequency, and formulation. The median time to complete second-source verification was 9 minutes (interquartile range, 5-17 minutes).

CONCLUSION: Second-source verification at the time of hospital admission helps identify medication discrepancies and may improve medication use safety and prescribing pattern and, accordingly, may contribute to reducing medication errors.
