Assessing the impact of a mixed intervention model on the reduction of medication administration errors in an Australian hospital.

BACKGROUND

Medication errors remain one of the most common types of incidents reported in Australian hospitals. Studies have reported that for every 10 medication administrations, a medication administration error is likely to occur and reach the patient, potentially contributing to a preventable patient harm.

OBJECTIVE

To assess the impact of a mixed intervention model on medication administration errors in an Australian hospital.

METHODS

Two types of intervention model (human and system orientated) were implemented through collaboration with key stakeholders (nurses, educators, and policy makers) to reduce medication administration errors across this 650-bed multisite Australian hospital from August 2018 to June 2019. To assess the impact of the mixed intervention model, the total number of reported medication errors and the number of medication administration errors were retrieved from the hospital electronic medication management system for 12 months before (from June 2017 to July 2018) and after (from July 2019 to June 2020) implementation of all interventions.

RESULTS

Implementation of a mixed intervention model through collaboration with stakeholders resulted in significant reduction in the number of medication administration errors, and those with harm (from 68 to 55%, P < 0.0001 and from 12 to 8%, P = 0.0001 respectively). Additionally, the severity of medication administration errors was also reduced (HR 0.562, 95% CI (0.298-1.062)) in the post-intervention phase.

CONCLUSION

Introducing a mixed intervention model reduces medication administration errors across health settings and has the potential to drive excellence in healthcare.
