Among the most contentious legal and ethical issues concerning the use of electroconvulsive therapy (ECT) are the criteria for obtaining a valid consent to treatment and its administration to involuntarily hospitalized patients, with or without consent. This paper reviews the consent process, in particular the assessment of competence, as it is affected by the symptoms and clinical circumstances, including civil status, of those patients for whom ECT is prescribed. The ECT caseload at one psychiatric facility was reviewed to determine the diagnosis and civil status of each patient and the source of consent for each course of ECT prescribed over a 10-year period. Significant differences were found in the diagnostic distribution and the source of consent by diagnostic group between the 1,042 courses administered to informal patients and the 249 courses to involuntary patients. The results are discussed in the context of relevant Ontario legislation and hospital policies. Recommendations are made for the improvement of procedural safeguards to protect the autonomy of all patients.
The mental status examinations of 63 patients with a hospital discharge diagnosis of dementia were reviewed. The examination and documentation of most areas of cognitive function were found to be incomplete in the majority of cases. The need for a complete examination of cognitive function is discussed in relation to the natural history of dementia and in the context of recent developments in the classification of organic mental disorders.
Contemporary standards of practice of electroconvulsive therapy with respect to the treatment procedure, clinical indications, and dosage (number of treatments per course) are summarized. The actual clinical practice at one psychiatric hospital over a 16-year period, comprising 22,647 treatments, was compared to those standards. The most significant findings in this series were the over-representation of patients with a diagnosis of schizophrenia and the absence of any clinically significant difference in the treatment dosage for schizophrenia and affective disorders. The significance of these findings is discussed with respect to their identification of patient subgroups that warrant case auditing. In addition, the results are used as a basis for a critical examination of the rationale for the presently recommended maximum treatment dosages.
