Survival in a population-based cohort of dementia patients : Predictors and causes of mortality.
To examine predictors of survival time and causes of mortality in a population-based cohort of demented subjects.
Longitudinal naturalistic follow-up study.
A rural area in The Netherlands.
The study population consisted of 102 demented subjects derived from a population-based, two-stage prevalence study of dementia among subjects aged 65 and over.
Measurements and analysis
Survival analysis was performed using the Realized Probability of Dying as a measure of survival time.
Adjustment for duration and severity at study entry was employed in all analyses.
A substantial excess mortality was present among demented subjects as compared with their non-demented birth cohort.
Disorders related to dementia, such as cachexia, dehydration and pneumonia, were major causes of death.
Variables related to severity of functional impairment, aphasia and a shorter duration at study entry predicted a shorter survival in the study population.
