Objective:
Examine the overall incidence of medically treated depression in Denmark among individuals 15-44 years old, and estimate the 5-year cumulative incidence of psychiatric hospital care among individuals treated first in non-hospital-based care.
Methods:
We followed all individuals born in Denmark between 1969 and 1998 from age 15 or 2006 (whichever came first) until first depression treatment; death; emigration; or December 31, 2013. Incidence rates were estimated using Poisson regression. Cumulative incidence of hospital care following treatment in non-hospital care was estimated using Kaplan-Meier curves.
Results:
In this sample of 2 014 760 individuals, incidence rates of depression in non-hospital and hospital-based care in 2012-2013 were 6.6 (95% Confidence Interval: 6.5-6.7) per 1000 person-years and 1.5 (95% CI: 1.5-1.6) per 1000 person-years, respectively. Overall, 85-90% of first medical treatment for depression took place outside of psychiatric hospitals, but a quarter (26.3%) of individuals treated for depression received hospital care initially or within 5 years. Incidence of hospital care was higher in women and younger individuals.
Conclusions:
Most medical treatment for depression in Denmark takes place in non-hospital settings. Women and younger individuals are more likely to receive hospital care both initially and within 5 years after first antidepressant treatment.
