RESUMO
Objective Infections from methicillin-resistant Staphylococcus aureus are increasingly treated in longterm care facilities, but long-term care pharmacies face high costs in the provision of sterile vancomycin for intravenous administration. This study compares pharmaceutical costs of outsourced, compounded, and room temperature premixed vancomycin formulations in a long-term care pharmacy. Design This retrospective observational study reviewed 124 orders of vancomycin. Means for total pharmacy preparation time, pharmacist labor time, and extrapolated time over complete course of treatment were compared for three vancomycin preparations: outsourced, compounded by pharmacy, and room temperature premixed vancomycin formulations. Cost calculations were generated using ingredient costs as reported by the pharmacy and median pharmacist labor costs as published from national sources. Results Mean total preparation times and pharmacist preparation times were shortest for premixed vancomycin. Over full courses of treatment, mean pharmacy preparation time for compounded was 5 hours 3 minutes (mean of 28 treatments) and 2 hours 8 minutes for premixed (mean of 54 treatments). Data on pharmacist time in outsourced orders were not available. Total pharmacy costs were $993.94 for compounded vancomycin, $2220.34 for outsourced, and $809.36 for room temperature premixed vancomycin. Conclusion There were reduced preparation times for room temperature premixed vancomycin compared with compounded and outsourced formulations for skilled nursing facilities. As multiple drug-resistant organism infections are increasingly treated in long-term care, finding cost-effective approaches to medication provision from pharmacies is critical.
