Evaluation of Patients With Methicillin-Resistant Staphylococcus Aureus Hospital-Acquired Pneumonia Treated With Linezolid or Vancomycin

Multicenter, Retrospective, Observational Study to Evaluate Clinical and Economic Outcomes of Patients With MRSA Hospital-Acquired Pneumonia Treated With Linezolid Or Vancomycin

The objective of this study is to review the local management of patients with methicillin-resistant Staphylococcus aureus hospital-acquired pneumonia treated with vancomycin or linezolid with the goal to define if any difference exists among these antimicrobials in regard to clinical and economic outcomes.

Non-randomized, retrospective, observational study

Inclusion Criteria:

Patients will be enrolled in the study if they fulfill the following three inclusion criteria:

1. Protocol criteria for HAP/VAP: Criteria for making a correct diagnosis of HAP will be met if the patient develops a new or progressive pulmonary infiltrate associated with at least two of the following: new or increased respiratory symptomatology (cough, sputum or tracheal secretions, shortness of breath), fever or hypothermia, leukocytosis, left shift, or leukopenia, or deterioration of pulmonary function.
2. Isolation of MRSA from a respiratory sample or blood culture within 48 hours of the diagnosis of HAP/VAP
3. Treatment of MRSA HAP/VAP with either vancomycin or linezolid with incorporation of 100 patients in the vancomycin arm and 100 patients in the linezolid arm

Exclusion Criteria:
