Does a 6-factor prognostic index accurately predict 1-year mortality in medical patients 70 years or older after hospitalization?
A simple 6-factor prognostic index accurately stratifies 1-year mortality risk in hospitalized medical patients aged 70 years or older.
Our prognostic index, which used 6 risk factors known at discharge and a simple additive point system to stratify medical patients 70 years or older according to 1-year mortality after hospitalization, had good discrimination and calibration and generalized well in an independent sample of patients at a different site. These characteristics suggest that our index may be useful for clinical care and risk adjustment.
