title: The impact of potent antiretroviral therapy on the characteristics of hospitalized patients with HIV infection.
abstract: OBJECTIVE
  Despite advances in antiretroviral treatment, a large number of HIV-infected patients still require hospitalization. This study describes the characteristics of HIV patients requiring hospitalization before and after the advent of potent antiretroviral therapies.
  
  
  METHODS
  Information was collected on all HIV-positive patients admitted to the New York Hospital-Cornell Medical Center in New York City. Data was collected from 1 January through 30 June 1995, and during the same 6-month interval in 1997.
  
  
  RESULTS
  In each time period over 1500 outpatients were receiving treatment for HIV infection. There was a significant decrease in the incidence of admission [60.4 per 100 patient-years (PY) in 1995, 28.8 per 100 PY in 1997], and length of stay (10 versus 8 days). The median CD4 cell count of all HIV-infected patients admitted to the hospital doubled: 37 x 10(6)/l in 1995 versus 80 x 10(6)/l in 1997. However, there was no significant change in the median CD4 cell count of patients diagnosed with opportunistic infections. The incidence of the most common diagnosis (bacterial pneumonia, 8.0 per 100 PY in 1995 versus 3.6 per 100 PY in 1997) and the most common opportunistic infection (Pneumocystis carinii pneumonia 7.6 per 100 PY in 1995 versus 2.4 per 100 PY in 1997) decreased significantly.
  
  
  CONCLUSIONS
  Since the introduction of potent antiretroviral therapy, a significant decrease in the incidence of hospital admission and opportunistic infections has occurred. There has been a doubling of the median CD4 cell count of inpatients. There has been no significant change in the median CD4 cell count at which patients present with opportunistic infections.
