Quality of antimicrobial prescribing improved by the introduction of ePrescribing at Auckland City Hospital.

Improving antimicrobial prescribing is a difficult process often requiring labour-intensive, multi-modal interventions. Many hospitals have introduced ePrescribing systems but the effect on antimicrobial prescribing, without treatment choice decision support systems, has not been well described. We sought to determine whether the introduction of ePrescribing improved prescribing quality. Patient records for inpatients on four rehabilitation wards, two using ePrescribing and two using the National Medication Chart, during February 2017, were retrospectively reviewed to identify all antimicrobial prescriptions, which were then reviewed for quality. Documentation of indication was significantly better on ePrescribing wards (45/46, 98%) compared to National Medication Chart wards (47/59, 80%). Adherence to guidelines (32/46, 70% vs 33/59, 56%), appropriateness of therapy (42/46, 91% vs 50/59, 85%) and documentation of duration, stop or review dates (35/46, 76% vs 38/59, 64%) did not significantly differ. ePrescribing can improve the quality of antimicrobial prescribing when Antimicrobial Stewardship principles are used in system customisation but cannot address all factors impacting on prescribing quality.
