Pharmacists play an essential role in medication safety through practices such as medication reconciliation and best possible medication history. This observational study found that 20% of patients presenting to surgical units at one French hospital over a two-month period had a medication error. Pharmacists intervened and resolved medication errors related to untreated indications, subtherapeutic dosages, and prescriptions without an indication.

Pharmacists play a crucial role in ensuring patient safety in hospitalized patients. However, prior studies have found inconsistent effects of medication reconciliation performed by pharmacists at preventing medication errors. This systematic review determined that pharmacist-performed medication reviews may reduce readmissions and emergency department visits after discharge, but the overall quality of the literature was not robust enough to definitively reach this conclusion.
