Abstract
OBJECTIVES: To quantify medication-related errors, in particular prescribing errors, identified by pharmacists and assess their potential impact on inpatients in community hospitals. METHODS: Pharmacists recorded all interventions to optimise medication for community hospital inpatients over 14 days in November 2013. Interventions were subsequently classified by type (prescribing error; omitted or delayed drug administration; or attributable to other issues) and rated for potential clinical impact. RESULTS: 15 organisations participated in the study reporting on 4077 medication charts. In total, 52 033 medication orders were screened by pharmacists. A medication-related intervention was made on 1 in 3 charts for one or more medications. A total of 2782 interventions were recorded. The majority were categorised as a prescriber error (67%, 1872/2782). The remainder (33%, 910/2782) were not directly attributable to prescriber error; of these omitted and delayed medicine administration accounted for 11% (298/2782). Of the 1872 interventions classed as prescriber error, a third, if left undetected, might have caused moderate or severe patient harm. The prescribing error rate was 3.6 errors per 100 medication orders. CONCLUSIONS: Pharmacists reported intervening to improve the care provided to over a third of patients in this study. Two-thirds of interventions were in response to prescribing errors, a third of which, if left undetected, could have led to harm. The results suggest that inpatients in community hospitals are subject to prescribing errors at a rate comparable to those seen in acute and mental health hospitals. A clinical pharmacy service is vital to ensure patient safety in community hospitals.
