Rapid diagnostic test and use of antibiotic against methicillin-resistant Staphylococcus aureus in adult intensive care unit.
Ventilator-associated pneumonia (VAP) due to methicillin-resistant Staphylococcus aureus (MRSA) is associated with excess mortality and costs. Molecular biology test allows rapid identification of MRSA in sputum with high negative predictive value. We hypothesized that use of a rapid diagnostic test in patients with suspected VAP was associated with reduced use of antibiotics directed against MRSA. ⋯ The mean cost of anti-MRSA treatment by patients in the first group was 63 ± 223 €, and 13 ± 52 € in the second group (p < 0.001). This study shows that a rapid diagnostic test was associated with reduced use and cost of anti-MRSA antibiotics in patients with suspected VAP. These results should be confirmed by further multicenter prospective studies.
