Multicenter Study Clinical TrialPrognosis with mechanical ventilation: the influence of disease, severity of disease, age, and chronic health status on survival from an acute illness.
This report presents a model for relating readily available clinical and physiologic measurements to prognosis from mechanical ventilation. Using data from 571 acutely ill, ventilated patients admitted to the intensive care units of 12 hospitals, it illustrates the relationship between the disease, the initiating respiratory failure, the acute severity of the disease, and the patient's age and chronic health status and the patient's probability of survival. ⋯ After 3 days of ICU treatment, estimates for hospital mortality increased to 97% (39 patients). We believe that such estimates, when available from a larger number of patients and combined with additional information on the patient's desires, expectations, preillness quality of life, and prognosis for long-term survival, can be helpful in decisions to withhold and withdraw mechanical ventilation.

ReviewIntensive care unit survival of patients with systemic illness.
Many patients with systemic illness are admitted to intensive care units (ICUs) and placed on life support. This occurs in patient populations even when the projected mortality rate might be as high as 80 to 90%. Patients with systemic illness often are life-support-dependent in ICUs as chronically critically ill patients for many weeks. ⋯ Numerous studies have identified that chronologic age is associated with increased mortality rates. However, a better assessment would be biologic age, which would take into account both chronologic age and health status. ICU survival of patients with cancer, hematologic neoplasms, renal failure, liver failure, AIDS, and burns is reviewed.(ABSTRACT TRUNCATED AT 250 WORDS)
