[Prevalence of infectious diseases at the Vaud University Hospital Center].
The prevalence of infectious diseases at our hospital (Centre hospitalier universitaire vaudois, Lausanne [CHUV], 900 beds) was studied retrospectively over a two years period (1980-1981). The medical diagnosis of 30203 patients recorded in the computerized medical archives, representing 93% of the patients admitted during the period of observation, was reviewed. To assess the reliability of the computerized data, quality control was carried out through detailed analysis of all the histologically proven appendicitis recorded during 1981. 88% of the histologically proven appendicitis were registered in the computer and the diagnosis was specific in 87% of cases. An infectious disease was the primary reason for admission in 12.8% of the patients (3873) during the study period. Altogether, 20.2% of patients presented with an infection during their hospital stay. Because of the retrospective nature of the study it was not possible to determine whether these additional infections were nosocomially acquired. The organ systems most frequently infected were the respiratory tract (28.5% of all infections), the digestive tract (20.5%), the skin and osteoarticular system (16%) and the urogenital tract (11.6%). An infection was the primary reason for admission of 40.2% of the patients hospitalized in the dermatology service, of 19.7% of patients admitted in internal medicine, of 15-17% of the patients admitted in pediatrics, ENT and general surgery, and of 1-2% of the patients admitted in neurosurgery and radiotherapy. These observations highlight the continuing importance of infectious diseases in a modern hospital, in spite of high socio-economic levels, stringent hygiene and epidemiologic measures, and modern antibiotic availability.
