Electroconvulsive Therapy: A Canadian Perspective

Abstract

Recent ECT practices in Canada are reviewed from a historical perspective with respect to specific criticisms. Utilization is decreasing; utilization rates vary widely between Provinces and between regions; disproportionate numbers of females have been receiving ECT; a substantial group of patients diagnosed as neurotic and schizophrenic continue to receive ECT; criteria and guidelines for its use are not consistently applied. Expected rates of ECT used are estimated, based on theory and practice as well as on published data on the epidemiology of affective disorders. Data on actual Canadian usage are reviewed and compared with an estimated minimum ratio of 30–45+ cases per year of non bi-polar depression per 100,000 population requiring ECT. Results show that there may be a substantial number of patients in some Provinces for whom ECT is the best available treatment and who are not receiving it. There is some ethical concern associated with possible under-use of ECT as the best therapy available for certain patient groups. Clinical cases and patterns of care should be reviewed at the hospital level to determine how best to effect improvements in the use of this treatment.
