Some influences on regional variation in frequency of prescription of electroconvulsive therapy.

A Republic of Ireland national survey of electroconvulsive therapy (ECT) showed wide inter-hospital variation in ECT rates. Psychiatric admission rates, professional attitudes, and patient turnover were found to predict these rates. No significant association was found between ECT rates and public/private care or other socio-economic factors. A limited examination of British admission data revealed a similar set of correlations, suggesting that the findings may apply in non-profit health-care systems outside the Republic of Ireland.
