Long-term quality of life outcomes after ECT vary widely, with individuals responding well to initial treatment, being married, and having a less chronic course of illness experiencing the best outcomes. Approximately 40-50% of individuals experienced clinically meaningful improvements after ECT.
Background: Electroconvulsive therapy (ECT) is highly effective for treatment-resistant depression (TRD), and previous studies have demonstrated short-term improvements in quality of life (QoL) after ECT. However, longterm QoL after ECT has not been studied, and the baseline patient characteristics that predict long-term QoL remain unknown. Methods: Seventy-nine subjects with unipolar or bipolar TRD were enrolled in this prospective longitudinal observational study. Physical, psychological, social, and environmental QoL domains were measured with the abbreviated World Health Organization Quality of Life scale (WHOQOL-BREF) at baseline and every 6 months for up to 2 years after ECT. Baseline sociodemographic and clinical features were tested for association with long-term QoL. Results: Long-term follow-up data were available from 49 participants. Relative to baseline, average psychological and physical QoL improved during the follow-up period (Hedges' effect size: 0.27-0.83). About 40-50% of individuals experienced clinically meaningful improvement. Subjects with better initial antidepressant response with ECT reported better QoL over the subsequent two years. Long-term QoL improved most among individuals who were married, those without disability status, and those with psychotic features or shorter depressive episodes at baseline. Limitations: Participants were from a single US academic center and mainly of European ancestry, so findings may not generalize to other settings or ethnicities. The observational design does not allow causal inferences. Conclusions: Long-term psychological and physical QoL outcomes vary widely after ECT. Individuals with the best outcomes are those who respond well to ECT initially, married people, and those with a less chronic course of illness.
