title: Delays in tuberculosis isolation and suspicion among persons hospitalized with HIV-related pneumonia.
abstract: BACKGROUND
  Despite awareness of HIV-related tuberculosis (TB), nosocomial outbreaks of multidrug-resistant TB among HIV-infected individuals occur.
  
  
  OBJECTIVE
  To investigate delays in TB isolation and suspicion among HIV-infected inpatients discharged with TB or Pneumocystis carinii pneumonia (PCP), common HIV-related pneumonias.
  
  
  METHODS
  Cohort study during 1995 to 1997.
  
  
  METHODS
  For PCP, 1,227 persons who received care at 44 New York City, Chicago, and Los Angeles hospitals. For TB, 89 patients who received care at five Chicago hospitals.
  
  
  METHODS
  Two-day rates of TB isolation/suspicion.
  
  
  RESULTS
  For HIV-related PCP, Los Angeles hospitals had the lowest 2-day rates of isolation/suspicion of TB (24.3%/26.6% vs 65.5%/66.4% for New York City and 62.8%/58.3% for Chicago, respectively; p < 0.001 for overall comparison by chi(2) test for each outcome measure). Within cities, hospital isolation/suspicion rates varied from < 35 to > 70% (p < 0.001 for interhospital comparisons in each city). The Chicago hospital with a nosocomial outbreak of multidrug-resistant TB from 1994 to 1995 isolated 60% of HIV-infected individuals who were discharged with a diagnosis of HIV-related TB and 52% discharged with HIV-related PCP, rates that were among the lowest of all Chicago hospitals in both data sets.
  
  
  CONCLUSIONS
  Low 2-day rates of TB isolation/suspicion among HIV-related PCP patients were frequent. One Chicago hospital with low 2-day rates of TB isolation/suspicion among persons with HIV-related PCP also had low 2-day rates of isolation/suspicion among confirmed TB patients. That hospital experienced a nosocomial multidrug-resistant TB outbreak. Educational efforts on the benefits of early TB suspicion/isolation among HIV-infected pneumonia patients are needed.
