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.
DESIGN: Cohort study during 1995 to 1997.
SETTING: 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.
MEASUREMENTS: 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.
CONCLUSION: 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.
