Objective:
The transition to area under the curve (AUC) vancomycin monitoring requires substantial updates in pharmacy policies and procedures. The study facility was tasked with transitioning from a consult-based collaborative agreement to an automatic pharmacist management policy on all intravenous (IV) vancomycin orders. The purpose of this quality assessment (QA) study was to evaluate the effectiveness of this transition.
Methods:
The primary outcome was the proportion of patients with pharmacist assessment of pharmacokinetics and dosing with documentation in IV vancomycin treated patients from January-June 2020. Secondary outcomes included the proportion of AUC24 levels within therapeutic range, the incidence of acute kidney injury (AKI) and treatment failures in patients treated ≥72 hours compared to a historical, trough-based cohort.
Results:
There were 88 patients in the QA analysis with 100% having a pharmacist assessment with documentation. There were 34 patients treated ≥72 hours in the AUC group, 36 in the trough-based group. AUC24 fell within desired range in 45% of monitored patients. Rates of AKI (9% vs 11%, p = 0.75) and treatment failures were similar (3% vs 0%, p = 0.3).
Conclusion:
The transition from consult-based to an automatic pharmacy management agreement was successful with similar safety and efficacy compared to a historical trough-based cohort.

Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
