Research objective: 

Using linked longitudinal population-based provincial health administrative datasets, this project aims to

(1) determine mortality of Super-Seniors (those aged 85 by end 2004 having avoided cancer, cardiovascular disease, major pulmonary disease, dementia and diabetes) and a sex and birth year matched comparison population (controls) of individuals with at least one of the 5 major diseases that the Super-Seniors have avoided; who die or develop at least one of the 5 major diseases of interest by age 85; and (when applicable) their cause of death;

(2) quantitate the Super-Seniors use of health care prior to age 85, including hospitalizations (avoidable and non-avoidable), use of outpatient physician-ordered services (including preventive care), mental health and community care services, and prescription drugs, and compare to usage by controls in BC up to age 85 years of age, to determine which group lived to age 85 with the fewest healthcare interventions

(3) determine later morbidity, including specific major diseases, and related healthcare utilization, compared to controls; and evaluate the timing of morbidity among Super-Seniors and controls living beyond 85 years of age, to determine if Super-Seniors show compression of morbidity (shorted period of morbidity prior to end of life) relative to controls. Results will be adjusted for socio-demographic (ie sex, socioeconomic status) and health system (ie region of care, urban/rural care setting) factors affecting outcomes.


For aim 1:Super-seniors have decreased risk of mortality, compared with a sex- and birth year -matched control group, since they have avoided the five most costly diseases of aging.

For aim 2: Previous health care utilization, including prescription drug use, is also lower for super-seniors, compared with a sex- and birth year -matched control group; use of preventive services is higher.

For aim 3: Later risk of morbidity occurs within a shorter period of time for Super-Seniors relative to controls.
