Electroconvulsive treatment improves major depressive disorder when introduced earlier: Study

Japan: The prediction model created by Kazuki Nakajima and colleagues for electroconvulsive treatment (ECT) remission suggests that introducing ECT earlier in the treatment can improve clinical outcomes. The results of this study were published in The Journal of Clinical Psychiatry.

The most common and incapacitating mental condition in the world, major depressive disorder, is a major contributor to disability on a global scale. These individuals are categorized as having depression that is challenging to treat and are potential candidates for electroconvulsive treatment. Previous electroconvulsive treatment response prediction models were mostly dependent on neuroimaging data, which prevented broad use for severe patients in practical clinical settings. As a result, the objectives of this study were to (1) develop a therapeutically viable prediction model for ECT remission using just clinical data, and (2) identify key elements in the prediction model.

Data from patients who got ECT at Keio University Hospital and had depression (unipolar major depressive disorder or bipolar disorder) diagnosed according to DSM-IV-TR criteria were gathered through a retrospective assessment of cases (recorded between April 2012 and March 2019). Candidate features were drawn from clinical traits. A light gradient boosting machine was utilized to make predictions, and our prediction model was validated using 5-fold cross-validation.
