This article reviewed the influence of a pharmacist-driven antimicrobial stewardship/ optimization service in a non-trauma emergency department of a hospital. The impact of a nurse-driven chart review was compared with a pharmacist-driven chart review. Impact was based on the number of clinical interventions made, along with resistance patterns identified from wound and urine cultures. The nurses assessed 499 patients with positive cultures, and intervened on 50% of the cultures which indicated the need for an intervention. The pharmacists assess 473 patients with positive cultures, and intervened on 80% of those that needed intervention. Interventions were based on inappropriate therapy. Also, E. coli, the most frequently isolated urinary organism, displayed a fluoroquinolone resistance rate of 38%.
This antimicrobial stewardship program showed 30% more pharmacist interventions compared to nurse interventions for “bug-drug” mismatches. Proper prescribing of antibiotics is an essential part of offsetting antibiotic resistance. This program shows that pharmacists are a key part of modifying antimicrobial therapies when needed. The high fluoroquinolone resistance rate suggests that alternative therapies may be better for some urinary tract infections, such as nitrofurantoin.
I thought this was an interesting article, because of the increase in antibiotic resistance and various efforts to offset this increase. It seems that the pharmacists are in a better position to assess and address proper prescribing of antibiotics than the nurses, because ultimately they are the medication experts. With this in mind, do you think it is beneficial for pharmacists to be able to prescribe antibiotics to patients?
