Incidence and risk factors for potentially suboptimal serum concentrations of vancomycin during cardiac surgery

Table 4 Risk factors for vancomycin levels under 10 mg/L - multivariate binary logistic model

	OR	95%CI	P-value
Age at surgery (>70 yr vs ≤ 70 yr)	0.69	0.36-1.28	0.245
Gender (Female vs male)	0.54	0.30-0.97	0.039
BMI (> 25 vs ≤ 25)	1.99	1.15-3.45	0.015
CrCl (> 70 mL/min vs ≤ 70 mL/min)	1.92	1.09-3.40	0.024
Vancomycin dosage (>15 mg/kg vs ≤ 15 mg/kg)	0.75	0.36-1.57	0.451

BMI: Body mass index; CrCl: Creatinine clearance.
