In the treatment of hospital acquired staphylococcal pneumonia, the incidence of methicillin-resistant staph in the local facility will be very impoant. In most hospitals, methicillin-resistant staph is common enough to require initial therapy with vancomycin.

Antibiotic therapy should be based on the incidence of methicillin-resistant staphylococci in that hospital
