A real-world analysis of antidepressant medications in US veterans aged 60 years and older: a comparative analysis
Publication: Journal of Comparative Effectiveness Research
Abstract
Aim: To compare the safety and efficacy of antidepressants (AD) among older adults with major depressive disorder (MDD) by assessing treatment change, augmentation and hospitalization rates. Methods: This retrospective study analyzed data from the Veterans Affairs (VA) database, including 142,138 patients aged ≥60 years diagnosed with MDD. Patients prescribed bupropion, citalopram, duloxetine, escitalopram, fluoxetine, mirtazapine, paroxetine, sertraline, or venlafaxine were included. Outcomes were treatment change, augmentation and hospitalization rates. Hazard ratios (aHRs) were calculated using sertraline as the reference. Results: Of the patients, 39.6% required augmentation, 18.1% changed antidepressant treatment and 13.3% were hospitalized. The corresponding incidence rate was 544, 124 and 122 events per 1000 person-years. Compared with sertraline, mirtazapine users had the highest AD change risk (aHR 1.34, 95% CI: 1.29–1.40), while duloxetine users had the lowest (aHR 0.87, 95% CI: 0.83–0.92). Duloxetine also had the lowest augmentation risk (aHR 0.89, 95% CI: 0.86–0.92). Mirtazapine users also had the highest risks of augmentation (aHR 1.15, 95% CI: 1.12–1.18) and hospitalization (aHR 1.14, 95% CI: 1.07–1.23). Bupropion had the lowest hospitalization risk (aHR 0.77, 95% CI: 0.71–0.84). Conclusion: Antidepressant choice significantly influences treatment outcomes in older adults with MDD. Duloxetine demonstrated the best profile with the lowest risks of AD change and augmentation, while mirtazapine posed the highest risks of all three outcomes. Personalized treatment strategies are crucial to improving outcomes in this population.
Plain language summary
What is this article about?
This article looks at how different antidepressants work for people aged 60 years or older who have major depressive disorder (MDD), a common and serious mental health condition. Older adults often experience unique challenges with depression, including side effects from medications and a higher likelihood of needing to change treatments. The study analyzed real-world data from the US Department of Veterans Affairs to better understand three key outcomes for older adults taking antidepressants:
1.
How often they change antidepressant.
2.
How often they need additional medications (augmentation).
3.
How often they are hospitalized.
What were the results?
The study found that:
•
Changing antidepressant: About 18% of patients changed their antidepressant. Duloxetine was the least likely to be changed, while mirtazapine and citalopram had the highest risks of being changed.
•
Adding medications (augmentation): Nearly 40% of patients needed an additional medication. Duloxetine and bupropion were the least likely to need augmentation, while mirtazapine had the highest risk.
•
Hospitalization: Only 13.3% of patients were hospitalized. Mirtazapine was associated with the highest risk of hospitalization, while bupropion had the lowest.
What do the results of the study mean?
The study highlights that not all antidepressants work the same for older adults. Some medications are more likely to require changes or additional treatments, and some are linked to higher risks of hospitalization. This information can help doctors make better decisions when prescribing antidepressants to older patients, balancing the potential benefits with the risks of side effects or complications. Importantly, the study does not recommend one antidepressant over another but aims to provide a clearer understanding to guide treatment choices. This summary is intended to make the study more accessible to patients, caregivers and advocates who want to understand how depression treatments work in older adults.
