[Criteria for the hygienic appraisal of intensive care units (author's transl)].

7 intensiv-care-units (I.U.C.) were compared by analysing the charts of 100 patients from each station. They showed remarkable differences concerning the diagnosis of admittance, age and other factors related to the risk of infection. Consequently, kind and number of intensive care related medical procedures, the use of antibiotics, the duration of the patients stay on the station and the death rate differed widely. Some criteria concerning the layout, personnel, organisation and therapy on I.C.U. are named, which are mainly related to the patients condition and to the thereby given risk of infection.
