Pharmacy services and medication errors in hospital: a narrative review by point in the pathway

Description

A medicine given on a ward has passed through several pairs of hands. A doctor prescribes it, a pharmacy checks and supplies it, a nurse gives it, and at every handover something can go wrong: the wrong dose, the wrong strength, a drug the person stopped taking months ago, a dose that was never given at all. Hospital pharmacies run services to catch these: pharmacists on ward rounds, medicines reconciliation at admission and discharge, checks built into dispensing. How much any of it reduces errors is less settled than it looks. Studies count errors in different ways, and some count the interventions pharmacists made, which is a count of catches rather than of errors. Reported rates differ many times over between hospitals doing similar work, which may say more about the counting than the care. And an error is not the same thing as harm; most are intercepted or come to nothing. This review reads the evidence by the point in that pathway where the service acts. Before any of it can be compared, the team has to agree what counts as an error.
