Admission of AIDS patients to a medical intensive care unit: causes and outcome.

As the number of cases of AIDS increases, it is important to determine whether ICUs can be productively and safely used for this patient population. From July 1981 to March 1987, 216 patients were admitted to the medical ICU: 166 (77%) were admitted for procedures and 50 (23%) were admitted for life-sustaining support. Most of the patients were admitted for respiratory failure (36 of 50), primarily as a result of Pneumocystis carinii pneumonia. Other patients were admitted for cardiovascular instability (six of 50 patients), CNS dysfunction (four patients), or other reasons (four patients). Of 50 patients admitted to the ICU, 13 (26%) were alive 3 months after hospital discharge. Despite 25 needle-stick injuries and 56 mucosal splashes involving human immunodeficiency virus (HIV)-infected patients and staff, no staff member converted HIV serology. These results suggest that AIDS patients may benefit from ICU admission. These patients appear to pose a low risk to the hospital staff in terms of occupationally acquired HIV infection, but strong emphasis needs to be placed on minimizing accidental exposures to potentially infected body fluids and to adhering to universal precautions.
