Abstract
AimsTo evaluate clinical outcomes and allocation of hospital costs associated with empirical use of vancomycin or linezolid for hospital-acquired pneumonia (HAP) in the People’s Republic of China.MethodsHospital episodes including HAP treated by vancomycin or linezolid between 2008 and 2012 in a Chinese tertiary care hospital were retrospectively identified from hospital administrative databases. Propensity score methods created best-matched pairs for the antibiotics. The matched pairs were used for adjusted comparisons on clinical response and allocation of hospital costs. Multiple regression analyses adjusting residual imbalance after matching were performed to confirm adjusted comparisons.ResultsSixty matched pairs were created. Adjusted comparisons between vancomycin and linezolid showed similar clinical response rates (clinical cure: 30.0% versus 31.7%, respectively; P=0.847; treatment failure: 55.0% versus 45.0%, respectively; P=0.289) but a significantly lower in-hospital mortality rate for vancomycin (3.3% versus 18.3%, respectively; P=0.013). After further adjusting for the imbalanced variables between matched treatment groups, the risks of treatment failure associated with the two antibiotics were comparable (odds ratio: 1.139; P=0.308) and there was a nonsignificant trend of lower risk of in-hospital mortality associated with vancomycin (odds ratio: 0.186; P=0.055). The total hospital costs associated with vancomycin had a nonsignificant trend of being lower, likely because of its significantly lower acquisition costs (median: RMB 2,880 versus RMB 8,194; P<0.001; 1 RMB =0.16 USD).ConclusionIn tertiary care hospitals in the People’s Republic of China, empirical treatment of patients with HAP with vancomycin had a comparable treatment failure rate but likely had a lower in-hospital mortality rate when compared with linezolid. Vancomycin also costs significantly less for drug acquisition than linezolid when treating HAP empirically.
