Aims and methodWe conducted a retrospective audit of 100 discharge summaries to evaluate the accuracy of medication recording and the recording of as required (PRN) prescribing, and to see whether or not general practitioners were advised on how long to continue the latter. After a formal guideline was introduced we conducted a re-audit.ResultsThere was an improvement in summaries recording medication correctly (from 64 to 83%). The number of summaries with one or more missing medications halved and PRN sedative prescribing reduced from 18 to 3%, but provision of advice on the latter did not improve.Clinical implicationsAccurate recording of medication in the discharge summary is an important element of the transfer of patient care to the general practitioner. Medication errors may pose serious health risks and undermine patient confidence in the service. The clinical audit and interventions implemented helped to reduce errors in medication recording in discharge summaries.
