Mirror-Image Study of Maintenance Electroconvulsive Therapy

Abstract

Objectives Electroconvulsive therapy (ECT) is a technique with proven efficacy in the treatment of severe psychiatric disorders. However, studies regarding its use as a maintenance therapy are scarce. The aim of the present study was to build knowledge in this area. Methods Data from 28 patients receiving maintenance ECT (M-ECT) were retrospectively collected and analyzed using a mirror-image design. Length of stay and readmissions were compared before M-ECT (control condition) and after M-ECT (experimental condition). Results Our results showed a decrease in both length of stay and number of readmissions after M-ECT, although the decrease in readmissions was moderated by a site effect. Conclusions The present study results reveal the potential benefit of M-ECT. Further studies are urgently needed to establish its usefulness as an alternative treatment for severe psychiatric disorders.
