Key result
After Medicare Part D implementation, older adults had lower 180-day antidepressant nonpersistence compared to younger adults (HR 0.76; 95% CI 0.66-0.88), reversing the pre-2006 trend.
Why the study?
Do antidepressant treatment patterns and 180-day nonpersistence differ between older and younger adults with depression?
Cohort
Yes
Do antidepressant treatment patterns and 180-day nonpersistence differ between older and younger adults with depression?
Hazard Ratio: 0.76 (95% CI 0.66–0.88)
Implementation of Medicare Part D was associated with substantial changes in antidepressant treatment patterns and improved persistence among older adults with depression.

Medicare Part D was associated with improved antidepressant persistence in older adults; leaves open causal policy effects on adherence.
Sanglier et al. (2011) conducted a cohort in Depression. Older age (≥65 years) vs. Younger adults (25-64 years) was evaluated on 180-day nonpersistence (after 2006) (HR 0.76, 95% CI 0.66-0.88). After Medicare Part D implementation, older adults had lower 180-day antidepressant nonpersistence compared to younger adults (HR 0.76; 95% CI 0.66-0.88), reversing the pre-2006 trend.
