Beyond the Shock: Navigating the Road to Recovery After Acute Electroconvulsive Therapy
Optimal Treatment Strategy for Electroconvulsive Therapy (ECT) Revealed
Research results have been published on the optimal treatment strategy for electroconvulsive therapy (ECT), which is used for depression and bipolar disorder. The study highlights the importance of continuing ECT treatment to prevent relapse.
In the case of depression, the relapse rate is as high as 80% even after successful ECT treatment. However, the latest research results show that continuing ECT is more effective in preventing relapse. The clinical results of treatment maintenance after acute ECT application conducted by Anders Jorgensen and his research team at the Copenhagen Psychiatry Center in Denmark were published in the international academic journal JAMA Psychiatry.
ECT is a treatment used in psychiatry that treats certain mental illnesses by inducing seizures through brief, controlled electrical stimulation of the brain. It is mainly used in urgent cases such as those that do not respond to drug treatment or are at high risk of suicide.
The research team undertook a cohort analysis comparing the prognosis of maintenance ECT with other treatment strategies after acute ECT. They examined the association between ECT continuation and the risk of hospitalization or suicidal behavior at 6–12 months using Cox proportional hazards regression and propensity score matching for all patients from the Danish National Patient Register who started ECT treatment between 2003 and 2022.
Of the 19,944 patients who received ECT treatment, 1,533 (7.7%) continued ECT after treatment. Compared with patients receiving short-term ECT, those receiving long-term ECT had a halving of the odds of experiencing unipolar depression and a more than two-fold increased risk of schizophrenia and schizoaffective disorder.
The treatment continuation group had a lower hospitalization rate than the short-term ECT group, with a 6-month adjusted hazard ratio of 0.68, and a Cox regression 6-month incidence rate ratio of only 0.51. There were no significant differences in the risk of suicidal behavior, and continuation of ECT was associated with a significant reduction in total treatment costs compared with the period prior to cessation of acute ECT.
The researchers concluded that continuing ECT after acute ECT decreased the risk of readmission and also reduced treatment costs. They added that maintaining ECT after successful ECT should be considered to prevent relapse in patients who do not respond sufficiently to other interventions.
This study provides valuable insights into the optimal treatment strategy for ECT, highlighting the importance of continuing treatment to prevent relapse and reduce treatment costs.
