An article in JAMA looks at a decision support system for the treatment of major depressive disorder. The study examined a web-based tool that helps patients choose antidepressants. This tool uses numerical comparisons to help patients make decisions. The results showed that the use of this tool reduces premature discontinuation of antidepressants. The article also highlights the importance of patient preferences in choosing treatment. In addition, JAMA has other articles on perinatal depression, dementia, and other medical topics.
