Background: The treatment of ventilator-associated pneumonia (VAP) secondary to methicillin-resistant Staphylococcus aureus (MRSA) remains controversial.
Methods: We performed a review of all blunt trauma patients diagnosed with MRSA VAP from June 2005 to June 2011. VAP for the first 3 years was diagnosed by sputum aspiration and treated with vancomycin. For the last 3 years of the study period, VAP was diagnosed with bronchoalveolar lavage and treated with linezolid.
Results: MRSA VAP patients treated with vancomycin had an average hospital length of stay (LOS) of 49 days (range 9-99 days), an average intensive care unit (ICU) LOS of 43 days (range 6-98 days), and average ventilator days of 34.4 (range 3-76 days). Seventeen MRSA VAP patients treated with linezolid had an average hospital LOS of 27 days (range 11-61), an average ICU LOS of 22 days (range 10-42) days, and average ventilator days of 16.6 (range 2-42).
Conclusions: Trauma patients who develop MRSA VAP appear to have fewer ventilator days and shorter ICU and hospital LOS when treated with linezolid.
