چکیده

Importance There is significant concern regarding increasing long-term antidepressant treatment for depression, beyond an evidence-based duration. Objective ۲ To determine whether adding Internet and telephone support, to family practitioner review to consider discontinuing long-term antidepressant treatment, is safe and more effective than practitioner review alone. Design Cluster-randomized controlled trial, between ۲۰۱۹ and ۲۰۲۳, with remote computerized allocation and ۱۲ months follow-up. Participants and researchers were aware of allocation, but analysis was blind.Setting ۱۳۱ UK family practices. Participants Adults receiving antidepressants for > ۱ year for a first episode of depression, or > ۲ years for recurrent depression, currently well enough to consider discontinuation, and at low risk of relapse. Of ۶,۷۲۵ patients mailed invitations, ۳۳۰ (۴.۹%) were eligible and consented. Interventions Internet and telephone self-management support, co-designed and co-produced with patients and practitioners. Outcomes Primary (safety) outcome: depression at six months (pre-specified complete cases analysis), testing for non-inferiority of the intervention within ۲ points on the PHQ-۹. Secondary outcomes (testing for superiority): antidepressant discontinuation, anxiety, quality of life, antidepressant withdrawal symptoms, mental wellbeing, enablement, satisfaction, use of services, and adverse events. Results Of ۳۳۰ participants recruited (۲۲۳ (۶۸.۶%) women; mean age ۵۴.۴ years; ۱۷۹ in intervention practices and ۱۵۱ in controls), ۲۷۶ (۸۳.۶%) were followed-up at ۶ months, and ۲۴۰ (۷۲.۷%) at ۱۲ months. The intervention proved non-inferior; in fact mean PHQ-۹ scores were slightly lower in the intervention arm at ۶ months in the complete cases analysis (۴∙۰ versus ۵∙۰; adjusted difference ۱∙۰۸; ۹۵%CI -۲∙۰۶, -۰∙۰۹; p=۰∙۰۳), but not significantly different in an ITT multiple imputation sensitivity analysis (adjusted difference -۰∙۸۹ (۹۵% CI -۱∙۹۰, ۰∙۱۱), p=۰∙۰۸). By six months antidepressants had been discontinued by ۶۶/۱۴۵ intervention arm participants ۳ (۴۵.۵%) and ۵۴/۱۲۹ controls (۴۱.۹%) (adjusted odds ratio ۱∙۰۲; ۹۵% CI ۰∙۵۲, ۱∙۹۹; p=۰∙۹۶). Antidepressant withdrawal symptoms and mental wellbeing were better in the intervention arm, but again differences were small. There were no significant differences in the other outcomes; ۱۵% of participants in each arm experienced adverse events. Conclusions In this randomized controlled trial of adding Internet and telephone support to practitioner review for possible antidepressant discontinuation, depression was slightly better with support, but it did not significantly increase discontinuation. Improvements in antidepressant withdrawal symptoms and mental wellbeing were also small. There were no significant harms. Family practitioner review for possible discontinuation is safe and effective for more than ۴۰% of patients willing to discontinue.
