| Résumé : | [BDSP. Notice produite par INIST ZyRCdR0x. Diffusion soumise à autorisation]. Context While hospitalization rates have declined overall, hospitalizations for acute lower respiratory tract infections have increased steadily since 1980. Development of new approaches for prevention of acute resplratory tract conditions requires studies of the etiologies of infections and quantification of the risk of hospitalization for vulnerable patients. Objective To determine the frequency of specific virus infections associated with acute respiratory tract conditions leading to hospitalization of chronically ill patients. Design Analysis of viral etiology of patients hospitalized with acute respiratory tract conditions between July 1991 and June 1995. Setting Four large clinics and related hospitals serving diverse populations representative of Harris County, Texas. Patients A total of 1029 patients who were hospitalized for pneumonia, tracheo-bronchitis ; bronchiolitis, croup, exacerbations of asthma or chronic obstructive pulmonary disease, and/or congestive heart failure. Main Outcome Measure Virus infection, defined by culture, antigen detection, and significant rise in serum antibodies, by underlying condition ; hospitalization rates by low-vs middle-income status. Results Ninety-three percent of patients older than 5 years had a chronic underlying condition ; a chronic pulmonary condition was most common. Patients with chronic pulmonary disease from low-income populations were hospitalized at a rate of 398. (...) |
