Predicting future functional status for seriously ill hospitalized adults : the SUPPORT prognostic model.
To develop a model estimating the probability of an adult patient having severe functional limitations 2 months after being hospitalized with one of nine serious illnesses.
Prospective cohort study.
Five teaching hospitals in the United States.
1746 patients (model development) who survived 2 months and completed an interview, selected from 4301 patients in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) ; independent validation sample of 2478 patients.
Measurements and Main Outcomes
Patient function 2 months after admission categorized as absence or presence of severe functional limitations (defined as Sickness Impact Profile scores =30 or as activities of daily living scores =4 [levels that require near-constant personal assistance]). A logistic regression model was constructed to predict severe functional limitation.
One third (n=590) of patients who were interviewed at 2 months had severe functional limitations.
Changes in functional status were common : Of those with no baseline dependencies (not dependent on personal assistance), 21% were severely limited at 2 months ; of those with 4 or more baseline limitations, 30% had improved.
The patient's ability to do activities of daily living was the most important predictor of functional status.
