Survival Prognosis in Very Old Adults - American Geriatric Society

Objectives

To determine whether simple functional indicators are predictors of survival prognosis in very old adults.

Design

In-person survey conducted over a 3-month period in 1998; assessment of survival over a 15-year follow-up period.

Setting

Denmark.

Participants

All 3,600 Danes born in 1905 and living in Denmark in 1998, were invited to participate regardless of residence and health; 2,262 (63%) participated in the survey: 1,814 (80.2%) in person and 448 (19.8%) through a proxy.

Measurements

Socioeconomic factors, medications and diseases, activities of daily living, physical performance, cognition, depression symptomatology, self-rated health, and all-cause mortality, evaluated as average remaining lifespan and chance of surviving to 100 years.

Results

Men aged 92 to 93 had an overall 6.0% chance of surviving to 100 years, whereas the chance for women was 11.4%. Being able to rise without use of hands increased the chance for men to 11.2% (95% confidence interval (CI) = 7.7–14.7) and for women to 22.0% (95% CI = 18.9–25.1). When combining this with a Mini-Mental State Examination (MMSE) scores from 28 to 30, the chances were 21.7% (95% CI = 11.5–31.9) for men and 34.2% (95% CI = 24.8–43.5) for women.

Conclusion

Chair stand score combined with MMSE score is a quick and easy way to estimate overall chance of survival in very old adults, which is particularly relevant when treatment with potential side effects for nonacute diseases is considered.
