The Comprehensive Prognostic Tool was developed in 6646 community-dwelling U.S. adults aged ≥70 years who were interviewed in the Health Retirement Survey in 2000 (mean age 78, 59% female, 86% white).
This Tool was internally validated using bootstrapping with the same 6646 participants from the Health and Retirement Study.
Discrimination:
Mortality: This prognostic tool sorts patients who died from patients who lived correctly 72% of the time (c-statistic).
ADL Disability: This prognostic tool sorts patients who developed ADL disability from patients who did not develop ADL disability 63% of the time (c-statistic).
Walking Disability: This prognostic tool sorts patients who developed walking disability from patients who did not develop walking disability 61% of the time (c-statistic).
Calibration:
The mortality model was well calibrated across all risk levels, with less than 7% difference between estimated and actual 10-year mortality rates.
The ADL disability model was well calibrated across all risk levels, with less than 6% difference between estimated and actual 10-year ADL disability rates.
The walking disability model was well calibrated across all risk levels, with less than 5% difference between estimated and actual 10-year walking disability rates.
