Your best guess of 10 year mortality risk

Lee Index

  • This index was developed in 11,701 community-dwelling adults from the eastern, western and central United States who were interviewed in the Health Retirement Survey in 1998 (mean age 67, 57% female, 81% white, 12% 4-year mortality)
  • The index was internally validated in 8009 Health Retirement Survey interviewees from the southern United States (mean age 67, 57% female, 71% white, 13% 4-year mortality)
  • Discrimination: This risk calculator sorts patients who died from patients who lived correctly 82% of the time (c-statistic).
  • Calibration: The model was well calibrated across all risk levels with less than 3% difference between estimated and actual mortality rates.

Schonberg Index

  • This index was developed in 16,077 community dwelling older adults who responded to the 1997-2000 National Health Interview (NHIS) (27% >80 years old, 60% female, 85% white, 17% 5-year mortality)
  • The index was internally validated in a random sample of 8038 from respondents from the same data source from 2001-2004(27% >80 years old, 60% female, 85% white, 17% 5-year mortality)
  • Discrimination: This risk calculator sorts patients who died from patients who lived correctly 75% of the time (c-statistic). The discrimination was the same in the independent validation study.
  • Calibration: The model was well calibrated across all risk levels with less than 10% difference between estimated and actual mortality.
