Compared to non-intervention group, patients in the intervention group had a significantly higher proportion of vancomycin monitoring (94.6% vs 75.8%, p < 0.001), higher proportion of patients with at least one vancomycin trough level in the therapeutic range of 10 - 20 mcg / mL (80.5% vs 53.0%, p < 0.001), higher proportion of patients with at least one vancomycin trough level in the therapeutic range based on types of infection (63.2% vs 27.0%; p < 0.001) and lower proportion of patients with trough concentration below targeted levels (27.6% vs 46.0%; p < 0.001).
