Background:
There is a lack of knowledge regarding some basic differences between different electroconvulsive therapy (ECT) treatment schedules.
Objectives:
To examine differences, including ECT technical parameters and length of stay, between thrice- and twice-weekly ECT treatment schedules.
Methods:
Prospective audit of the changeover period of administering thrice- to twice-weekly ECT in a Dublin psychiatric hospital.
Results:
Twice-weekly ECT was associated with significantly lower total electricity dosage administered, a tendency toward shorter overall hospital stay and fewer ECT treatments compared to thrice-weekly ECT.
Conclusions:
Our results support the current international trend toward giving ECT twice weekly.
