Electroconvulsive therapy without consent from patients: One-year follow-up study

IntroductionNo previous study has been designed to analyze the reasons for electroconvulsive therapy (ECT) without patients' consent. In the present study we compared the clinical characteristics and one-year outcomes between patients with refusal to undergo ECT and patients without competency for ECT consent. MethodsIn a retrospective cohort study, 29 patients were treated with ECT without providing consent between 1 January 2006 and 31 August 2010. A surrogate family member gave informed consent for ECT to meet current legal requirements. Patients were assigned to one of two groups: a consent-refusal group comprising patients who refused to give consent for ECT and could clearly say no or argue with psychiatric staff about receiving ECT; and a consent-incompetent group comprising patients who were incompetent for consent but underwent ECT passively or reluctantly without argument. ResultsThe patients were clinically diagnosed with schizoaffective disorder (n=6), psychotic disorder (n=12), bipolar I disorder (n=8) and major depressive disorder with psychotic features (n=3). The consent-incompetent patients had longer hospital stays and more recurrence in one year than the consent-refusal patients, which may be because the former group had more psychotic disorders and fewer mood disorders. All patients improved rapidly and efficiently. However, remission was temporal in two-thirds of patients and the rehospitalization rate in one year was 66% (n=19). DiscussionECT can be applied early, emergently and successfully to patients who have a wide range of psychiatric disorders and life-threatening conditions without threat of lawsuits, even during their first hospitalization.
