Two outbreaks of nosocomial infections with MRSA, one in a urological unit in connection with transurethral prostatectomy and the other in an orthopaedic clinic with infections after implantation of prosthetic hips, have been analyzed on the basis of typing MRSA by phage-patterns, plasmid profiles and genomic DNA fragment patterns. Main reasons for these outbreaks were obviously mistakes in hospital hygiene and an inappropriate antibiotic prophylaxis (in the first outbreak a quinolone over about 7 days, in the second a third generation cephalosporin). ⋯ As described by the example of an outbreak with MRSA in a municipal hospital, ICUs can play a special role in intrahospital spread of MRSA. The recently observed inter-regional clonal interhospital dissemination of MRSA in Germany is mainly due to a transfer of patients between hospitals; prewarning of the hospital of destination and a number of hygiene measures can prevent further spread.

Infections are a major cause of death in critically ill patients. As gram-positive organisms are more widespread and methicillin-resistant staphylococci (MRSA, MRSE) are easily distributed in overcrowded Intensive Care Units (ICU), extended hygienic procedures for infection control are most important. We hypothesize that strict regulations and educational programs for medical and nursing personnel are able to control the spread of resistant bacteria. ⋯ MRSA and MRSE isolated from surveillance cultures of bronchial secretions were reduced from an annual rate of 60.0% to 37.7% and 36.4% to 6.2% respectively between the years 1991 and 1992. Accordingly, the number of lower respiratory tract infections and the crude mortality could be reduced. We conclude that prompt implementation of control measures and continuous education of medical personnel are able to control an outbreak of infection with resistant staphylococci in an ICU setting.
