Effect of decision aid in selecting antidepressant

September 28, 2015

Use of a decision aid helped primary care clinicians and patients with moderate to severe depression select antidepressants together but had no discernible effect on depression control and medication use and adherence, according to an article published online by JAMA Internal Medicine.

Depression is a common, debilitating, and costly chronic mental illness affecting an estimated 17 percent of Americans. Pharmacotherapy is a primary treatment, but the efficacy of antidepressants is reduced by low patient adherence rates and premature discontinuation. Annie LeBlanc, Ph.D., of the Mayo Clinic, Rochester, Minn., and colleagues studied the effect of the Depression Medication Choice (DMC) encounter decision aid on quality of the decision-making process and depression outcomes. This aid was designed to help patients and clinicians consider available antidepressants and the extent to which they improved depression and other issues important to patients.

Primary care practices in 10 rural, suburban, and urban primary care practices across Minnesota and Wisconsin were randomly allocated to treatment of depression with or without use of the DMC decision aid, which consisted of a series of cards, each highlighting the effect of the available options on an issue of importance to patients for use during face-to-face consultations.

The study included 117 clinicians and 301 patients with moderate to severe depression considering treatment with an antidepressant. Compared with usual care, use of DMC significantly improved patients' decisional comfort, knowledge, satisfaction, and involvement. It also improved clinicians' decisional comfort and satisfaction. There were no differences in encounter duration, medication adherence, or improvement of depression control between groups.

"Further work in this area is necessary. The ideal decision support should include nonpharmacological options. A larger and longer trial to study the effect of the decision aid on adherence to therapy in patients selected because of nonadherence may be more informative. Larger studies are needed to identify subgroups (i.e., socioeconomic status) that may benefit more from using the decision aid. Identifying the amount and type of support needed to effectively embed the use of this decision aid in the routines of primary care practices to support its longitudinal use also remains to be determined," the authors write.

Commentary: The Role of Decision Aids in Depression Care

"While better clinical outcomes are typically the bottom line for most interventions, certain patient-centered outcomes may have an independent intrinsic value," writes Kurt Kroenke, M.D., of the Regenstrief Institute Inc., Indianapolis, in a commentary.

"For example, 79 percent of the patients in the trial expressed a preference for either being the principal decision maker or sharing medical decisions with their clinician. One wonders how often in a busy clinical setting, when there is a choice among medications to treat a disease, the clinician actually discusses the pros and cons of different options. It may be less important for short-term use of drugs to treat acute conditions. However, for medications prescribed for chronic use, informed patient input may be especially desirable. Decision aids could either be used routinely or targeted toward certain patients based on their decision-making preference, sociodemographic characteristics, and history of medication intolerance or prior treatment failures."

#535 Superior
Apologies for the delay getting this week's episode out! A technical glitch slowed us down, but all is once again well. This week, we look at the often troubling intertwining of science and race: its long history, its ability to persist even during periods of disrepute, and the current forms it takes as it resurfaces, leveraging the internet and nationalism to buoy itself. We speak with Angela Saini, independent journalist and author of the new book "Superior: The Return of Race Science", about where race science went and how it's coming back.
