The practice of infectious diseases in the 1990s: the Canadian experience.

Abstract

A survey of the members of the Canadian Infectious Disease Society was carried out to determine the content of an infectious diseases consultative practice in the 1990s. Respondents were asked to identify all new inpatient, outpatient, and telephone consultations during a 1-week period in 1990. Consultations were categorized by the infectious disease syndrome of the patient and by the microorganism that was identified. Bacterial infections were the most common cause of inpatient consultations, while viral infections were more common in outpatients. Consultations for parasitic infections were primarily for Pneumocystis carinii pneumonia related to infection with the human immunodeficiency virus (HIV). "Newer" infectious disease syndromes such as chronic fatigue syndrome, toxic shock syndrome, and Lyme disease were all represented in the responses for the 1-week study period. The significant impact of HIV infection on the overall consultative load suggests that there will be a continuing need for newly trained infectious disease consultants into the 21st century.
