Higher overall nosocomial infection rate because of increased attack rate of methicillin-resistantStaphylococcus aureus

摘要: Abstract Background: Methicillin-resistant Staphylococcus aureus has become a frequent cause of hospital-acquired infectious disease. However, the impact methicillin-resistant S. on overall nosocomial infection rate not been clearly defined. Methods: The University Alabama at Birmingham Hospital is tertiary care facility and participant in National Nosocomial Infections Surveillance system. Prospective, hospital-wide surveillance for infections was conducted 8 months per year during 1986 through 1991. Results: total increased from 4.5% 1987 to 5.9% 1990. This temporally associated with rise attack 0% 0.4%. remainder increase caused by other gram-positive microorganisms, including methicillin-sensitive aureus. We identified most commonly surgical intensive unit as lower respiratory tract infections. In contrast, frequently found neurologic etiologic agent wound Conclusions: common pathogen.
