Evaluation of medication reconciliation in an ambulatory setting before and after pharmacist intervention.

Author information

  • 1Regional Medical Center, Memphis, TN, USA.



To determine the accuracy of medication reconciliation in an internal medicine clinic and to evaluate pharmacist interventions targeted at improving the accuracy of medication reconciliation.


Prospective case series.


Memphis, TN, from October 2007 to March 2008.


180 adults attending an internal medicine appointment.


On patient arrival, a nurse completed the medication reconciliation form. In Phase 1 of the study, a pharmacist randomly selected and reviewed a patient's medication reconciliation form, interviewed the patient, and verified information if indicated. A total of 90 forms were reviewed and compared to determine baseline medication reconciliation accuracy. Education interventions were held with the medical and nursing staff, targeting areas for improvement. In Phase 2 of the study, 90 additional medication reconciliation forms were reviewed in the same manner. Phase 1 and Phase 2 results were compared to evaluate differences in accuracy after the pharmacist's education interventions.


Accuracy of medication reconciliation forms and number of potentially significant errors at baseline and after pharmacist interventions.


In Phase 1, 14.4% of medication reconciliation forms were correct. The remaining forms contained 190 potentially significant errors. After the education interventions, 18.9% of medication reconciliation forms were correct and the others contained 139 potentially significant errors.


Medication reconciliation accuracy is poor. Although education interventions showed a trend toward improvement, continued education training for staff and patients is needed in addition to other interventions to optimize this process and prevent medication errors.
