The goal of the study is to conduct a comparative randomized trial of electroconvulsive therapy (ECT) vs. ketamine for patients with treatment resistant depression (TRD) in a real world setting with patient reported outcomes as primary and secondary outcome measures.


Patients with treatment resistant depression who meet all inclusion criteria and do not meet any exclusion criteria will be randomized to either electroconvulsive therapy (ECT) three times per week or ketamine infusion two times per week. Patients will answer questionnaires about their symptoms prior to treatments. The acute treatment phase of the study will last three to five weeks. Depending on response to treatment, some patients will be followed for an additional six months.
