Medication errors and adverse drug events are common in outpatient settings. A review of 29 studies found an incidence of about 15 adverse drug events per 100 outpatients each year. Of these reported adverse drug events, 20% were judged as being preventable.
One source of outpatient medication error is discrepancies between what physicians prescribe and believe patients are taking, as recorded in patients' medication lists, and what patients actually take.
For those patients who have been recently discharged from a hospital with new medications, this service reconciles the patient’s previous medications along with the new medications that were prescribed at the hospital. The patient’s primary care provider is also alerted of the new medications added to their patient’s profile.
