Implementation of vancomycin dosing nomogram in an electronic prescribing system: an innovative tool in antibiotic stewardship

Abstract: Vancomycin (VAN) is the gold standard therapy for Methicillin-resistant Staphylococcus aureus (MRSA) infections such as bacteremia and endocarditis. However, VAN suboptimal dosing for serious infections caused by S. aureus isolates that have elevated minimum inhibitory concentration (MIC), could be associated with poor outcome. Better understanding of VAN pharmacokinetics and pharmacodynamics (PK/PD) has led to the creation of new recommendations with optimized dosing regimens for the treatment of MRSA infecti… Show more

“…21 For patients >130% of their ideal body weight (IBW), an adjusted body weight (ABW) equal to IBW + 0.4 (actual body weight − IBW) was used. 21,22 Actual body weight was used for patients less than their IBW, and IBW was used for normal-weight patients. Estimated CrCl (eCrCl) was capped at a clearance of 120 mL/min, as there are data supporting the capping of CrCl, and an inflated eCrCl would significantly impact the calculated AUC, resulting in an underestimation.…”

“…Estimated CrCl (eCrCl) was capped at a clearance of 120 mL/min, as there are data supporting the capping of CrCl, and an inflated eCrCl would significantly impact the calculated AUC, resulting in an underestimation. [22][23][24][25] The calculated AUC was related to the MIC of the patient-specific MRSA isolate. Vancomycin MIC was determined by VITEK-2, the standard at our institution.…”

“…(4) O conhecimento da farmacocinética (PK) e farmacodinâmica (PD) da vancomicina é fundamental para a otimização da terapia antimicrobiana. (5,6) Evidências científicas sustentam a importância da relação entre a Área sob a Curva (AUC24h) entre 400 e 600 e Concentração Inibitória Mínima (CIM) ≤ 1 mg /L, estando associada a eficácia, segurança e melhor desfecho clínico para pacientes. (5,6) Com base nesses dados, uma recente diretriz de prática clínica elaborada por várias sociedades americanas da área atualizou a dose de tratamento com vancomicina para 15-20 mg/kg a cada 8-12 horas, visando uma concentração sérica mínima de 15 a 20 mg/L para o tratamento de infecções graves em pacientes adultos.…”

Em paralelo, o modelo pediátrico é semelhante, com recomendação de dose de tratamento em crianças a partir dos 3 meses de 60 a 80 mg/kg/dia em doses divididas a cada 6-8 horas e 10 a 20mg/kg a cada 8-48h para neonatos e crianças até os 3 meses.…”
