We read with interest the study published by Song et al describing their retrospective analysis of the clinical response and hospital costs associated with the empiric use of vancomycin or linezolid therapy in patients with hospital-acquired pneumonia (HAP) in the People’s Republic of China.1 Results from matched comparisons showed similar clinical response (30.0% vs 31.7%; P=0.847) and treatment failure rates (55.0% vs 45.0%; P=0.289) but a significantly lower in-hospital mortality rate (3.3 vs 18.3%; P=0.013) for vancomycin-treated patients compared to linezolid-treated patients. Treatment failure rates (odds ratio [OR], 1.139; P=0.308) and risk of in-hospital mortality were comparable (OR, 0.186; P=0.055) between vancomycin- and linezolid-treated patients following further adjustment for an imbalance in variables between the matched treatment groups. Reported total hospital costs were not significantly different between vancomycin- (RMB 113,160) and linezolid (RMB 133,825)-treated patients (P=0.076).
