Abstract
Summary Computer-assisted diagnostic systems may accelerate transmission of microbiological reports and facilitate evaluation of the epidemiological situation and thus improve the collaboration between microbiologists and clinicians. This possible benefit is demonstrated by four examples. It became evident that incidences of pathogens in urinary tract and respiratory tract infections varied within a great range, depending on patient groups and clinical departments involved. Even within a department, different incidences of penicillin G and oxacillin-resistant coagulase-negative staphylococci were demonstrated. An apparent homogeneity of distribution of pathogenic bacteria in a hospital tends to be the result of a nondiscriminating overall evaluation, thus necessarily misleading the clinician especially in empirical chemotherapy. In the last example the evaluation of susceptibility testing revealed changing patterns of some pathogens during the observation period. By rapid exchange of data between the laboratories and the clinical departments supplying the clinicians with information relevant for actual therapeutical decisions, an empiric therapy may change into a so-called calculated therapy based upon data directly related to the site of infection, department and susceptibility patterns.
