Detailed Description

This is a prospective randomized control trial. There are two groups, study group and control group. Patients of study group accepted vancomycin strategies decided by a serum trough concentration model, and patients of control group accepted vancomycin dosage decided by attending physician. The primary endpoint is the incidence of reaching the target serum trough concentration, the secondary endpoint are clinical efficiency, antibiotic use and side effects such as acute kidney injury, etc.
