BACKGROUND Vancomycin is frequently used for the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections; however, determining the optimal dosage for neonates is difficult because of their immature renal function. METHODS Serum creatinine-based dosing was introduced in Kumamoto City Hospital Neonatal Medical Center. Serum trough concentration and therapeutic efficacy of vancomycin were evaluated before and after the introduction of the creatinine-based dosing. RESULTS When the therapeutic range of serum trough concentration of vancomycin at steady state was set to 5-15 µg/mL, 20 trough concentrations (48.8%) were within the therapeutic range and 21 trough concentrations were outside the therapeutic range before the introduction of the serum creatinine-based dosing. After the introduction of serum creatinine-based dosing, 18 trough concentrations (81.8%) were within the therapeutic range and 4 trough concentrations were not, and there was an increase in the number of patients with trough concentrations in the therapeutic range (P= 0.01; Fisher's exact test). CONCLUSIONS The serum creatinine-based dosing of vancomycin is useful in maintaining the appropriate serum level of vancomycin in neonates.
