Harms of First-Line Depression Treatment in Older Adults

Key Questions Draft

Draft Key Questions

Key Question 1: For older adults (>65 years) with major depressive disorder (MDD), what are the harms and comparative harms of different first-line treatment options?

Key Question 2: For different subgroups of older adults with major depressive disorder, what are the harms of different first-line treatment options?

Draft Contextual Question

For older adults (>65 years) with major depressive disorder, what is the effectiveness and comparative effectiveness of first-line antidepressant medications? Are there any differences in effectiveness for certain subgroups of patients?

Note: Contextual questions are not systematically reviewed, and use a “best evidence” approach. Information about the contextual question may be included as part of the introduction or discussion sections, and related as appropriate to the systematic review.

Draft Analytic Framework

Figure 1 depicts the key questions (KQs) within the context of the populations, interventions, comparators, outcomes, timings, and settings (PICOTS) considered in this review. The figure illustrates how older adults (>65 years) with Major Depressive Disorder may be treated for depression, and how these treatment options are associated with a range of potential adverse effects and outcomes. KQ address the harms of the first line pharmacologic treatments (KQ 1) for depression and the risk of adverse events associated certain patient subpopulations (KQ 2). The patient population of interest for KQ1 is older adults who have Major Depressive Disorder. The patient population of interest for KQ2 is subgroups of older adults such as patients with high risk of falls, history of fracture, taking other medications with central nerve system activity, nursing home residents, patient with dementia and multiple co-morbidities.  The first line pharmacologic treatments are Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin and Norepinephrine Reuptake Inhibitor (SNRIs), Bupropion and Mirtazapine. Outcomes of interest for KQ1 and KQ2 are measures of adverse clinical outcomes such as falls, fractures, hyponatremia, bleeding and mortality.

Background

Depression is a common psychiatric disease in older adults. Approximately 15–20 percent of adults older than age 65 in the United States have experienced depression1.

Multiple systematic reviews have shown that antidepressant medications are better than placebo for treating depression in older patients2. However, effects are modest and side effects are common. Depression treatment in older patients may be complicated by their other comorbid conditions, age-related physiologic changes, and potential interactions with other medications. As a result, certain treatment options may be contraindicated, inadequately dosed, or poorly tolerated. In addition clinicians must consider the balance of the risks and benefits of antidepressant medications, especially in comparison to other treatment options. While the effectiveness of interventions for treatment of depression in the elderly has been previously reviewed2 the harms of commonly used treatments of depression have not been well quantified specifically in older adults.

The American Geriatric Society (AGS) regularly compiles a list of medications that should be used with caution in older individuals called the Beers Criteria. Medications on the list are best avoided, avoided by those with specific conditions, or used with caution, at lower doses, or with careful monitoring. In 2015, this list recommended that clinicians avoid prescribing selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) in older adults with a history of falls or fractures3. However they noted that there may be situations when use of these medications may be appropriate and clinicians and patients must carefully weigh both benefits and potential harms4.

This review seeks to systematically review the harms and comparative harms of first-line depression treatment in adults over 65 years old, and will focus on those commonly prescribed in the US. This will assist clinicians and patients balance the benefits and harms of treatment and more fully inform decision-making about treatment options.
