The incidence of purulent staphylococcal infections at a large Swedish university hospital was followed during 3 years and has been described as an expression of the incidence of hospital infections.A marked decrease in the relative number of infections was found. The decrease was most evident among infections with ‘80/81’ strains and other antibiotic resistant hospital strains and was parallel in all the departments investigated. This is taken as an evidence for the assumption that the lowering of the amount of staphylococcal infections was brought about by a factor that was active throughout the hospital, probably some hygienic preventive measure.
A hygienic programme, which has been developed and maintained during several years at a large Swedish university hospital, is presented in detail. The composition and working methods of the Infection Control Committee are described and some economic calculations given. The possible connexion between the hygienic measures and a marked decrease of the incidence of infections is discussed. This decrease did not occur until a satisfactory method for the routine hand disinfection had been introduced, using a commercial antibacterial cleaner containing 3% hexachlorophene.
