Background: the new antidepressants are generally effective and safe for older people, but may have serious side-effects. The use has been rapidly increasing, but focus on upper age groups has been limited. The pattern of antidepressant use as death approaches has never been analysed.
Objective: to analyse the use of antidepressants among individuals aged 65 years and above with respect to time trends, age and proximity to death.
Design: population-based prescription study.
Setting: the County of Funen, Denmark, 1992–2004 (
470.000 inhabitants).
Results: the 1-year prevalence of antidepressants increases steadily over time in all age groups. Among the 65+ year-olds it also increases with age and differs substantially between the youngest and the oldest. Very high prevalences are observed: 26.8% among females 85–89 years old and 17.5% among males 85 years and above in 2004. In all age groups the use of antidepressants increases substantially with proximity to death in the last 3 years of life. In the last phase of life the use is independent of whether the patient dies at age 65 or 90 about 33% of females and 25% of males receive antidepressants in the last 6 months.
Conclusions: the use of antidepressants among 65+ year-olds increases with age and proximity to death to very high levels. Future studies may clarify the problems and diagnoses giving rise to the use of antidepressants for such a large proportion of older people, and especially the problems giving rise to treatment as death approaches.
