Abstract
OBJECTIVE: This study aimed to describe depression treatment patterns, identify unique trajectory groups using a group-based trajectory approach, and explore associated social determinants in older adults undergoing first-time depression treatment during a 3-year follow-up.
METHODS: This Danish register-based cohort study included all adults aged ≥ 65 who initiated depression treatment by redeeming first-time antidepressant prescriptions (no prescriptions in the last 10 years) between 2006 and 2015. The outcome of interest during the 2-year follow-up was depression treatment, assessed as antidepressant prescriptions redemptions and psychiatric hospital contacts for depression. Latent class growth analyses were applied to model treatment trajectories during 3 years. Multinomial logistic regression analyses were used to analyze adjusted associations between social determinates and trajectory group membership.
RESULTS: Among the 66,540 older adults (55.2% females, mean age: 77.3 years), we identified three distinct groups with unique patterns of depression treatment trajectories: 'brief-treatment' where individuals stopped depression treatment within 6 months (33.7%); 'gradual-withdrawal' (26.5%) where treatment was gradually stopped over 2 years; and 'persistent-treatment' where individuals continued depression treatment for the entire 3 years (39.8%). Females, single-person households, and residents of less-urbanized regions were associated with higher odds of membership in the 'persistent-treatment' group, while older age, widowhood or separation, and non-Danish ethnicities were associated with lower odds.
CONCLUSIONS: Three distinct patterns of depression treatment trajectories were identified in older adults, indicating differential clinical courses of depression-potentially influenced by social determinants, including sex, marital status, urban residence, and ethnicity. Early patient stratification and targeted interventions are crucial in depression care for older adults.
