If it ain't broke don't fix it: Lack of review of antimicrobials in 'well' patients - time for a CRP change.

Introduction: The rising prevalence of multi-resistant organisms threatens the efficacy of current antimicrobial treatments. Antibiotic stewardship is a key factor in slowing the development of resistance and must become part of a clinician's regular practice. National guidance unanimously emphasises the importance of a 48-hour review of antimicrobial prescriptions. We assessed the compliance of antibiotic reviews across two sites in Wales.

Method: Two cycles of data were retrospectively collected across two teaching hospitals in Wales prior and following introduction of an antimicrobial alert sticker. A univariate odds ratio for 48-hour referral stratified by C-reactive protein (CRP) was calculated in a logistic regression model for the cycle one data.

Results: One-hundred and thirty-nine patients were included in the cycle 1 data across both sites. We identified that patients with a CRP ≤100 mg/L (a marker of less severe infection) were less likely to have their antibiotic prescription reviewed by 48 hours.

Discussion: Patients with CRP ≤100 mg/L were less likely to receive a 48-hour review of their antimicrobial prescription. Compliance with review improved following introduction of a simple alert measure.
