Factors That Impact Treatment Decisions: Results From an Online Survey of Individuals With Bipolar and Unipolar...

To identify patient-reported factors that influence medication treatment decisions among individuals with bipolar and unipolar depression.

The Depression and Bipolar Support Alliance (DBSA) conducted an online survey February 2016 to April 2016 asking participants about factors that influence treatment decisions (eg, starting and stopping specific medications).

In total, 896 participants completed the survey (49.9% unipolar depression [n = 447] and 50.1% bipolar depression [n = 449]). The majority of respondents reported several previous medication trials. The most frequently reported factors impacting treatment decisions were side effects, doctor recommendations, cost, and how quickly the treatment will begin to work. The most common reason for changing treatments was ineffectiveness in the unipolar depression group and side effects in the bipolar depression group. Weight gain was the side effect that most commonly led respondents to discontinue a medication. When respondents currently using medications versus respondents not using medications were compared, doctor recommendations were more likely to be influential for those taking medications (P < .0001). Conversely, cost (P = .008) and impact on pregnancy/lactation (P = .045) were more likely to impact treatment decisions in participants not currently taking medications. Current medication use was associated with increased rates of perceived treatment effectiveness (P < .0001).

Side effects, doctor recommendations, cost, and rapidity of antidepressant effects were determined to be particularly important factors in making treatment decisions, with doctor recommendations being more influential for medication users and cost being more influential for participants not using medications. These findings highlight the importance of patient-centered factors in adjudicating treatment decisions.
