Abstract

Introduction:

Medication errors and adverse drug events (ADE) are a constant challenge for healthcare providers. The fast pace and unpredictable setting of an emergency department is especially prone to errors, contributing to 3% of all hospital related adverse events. This study evaluates the impact of computerized physician order entry (CPOE) used in conjunction with a decision support system (DSS) on the prevalence and types of interventions by pharmacy staff during the prescription-filling process in an emergency department (ED).

Method:

We conducted a retrospective cohort study comparing 6 months of pharmacy interventions before and after implementation of DSS in an academic tertiary care medical center ED located in Singapore. The primary outcome measure was overall incidence of prescription interventions made by pharmacy staff during the study period. The secondary outcome measure was the difference in the incidence of prescription interventions made by pharmacy staff within each category of intervention type. A Chi-square test was used to compare the difference in the prevalence of prescription interventions performed before and after implementation of DSS.

Results:

Pharmacy staff intervened to avert 1560 medication prescribing errors (836 before and 724 after DSS) for a total of 83912 patient encounters. The use of CPOE with DSS was associated with a statistically significant reduction (p

Conclusions:

Implementation of DSS was effective in reducing the overall number of prescription interventions performed by pharmacy staff and this implies its efficacy in reducing the number of medication errors due to prescribing errors in the ED.
