Abstract

Objectives: There is little research on the practice and effectiveness of electroconvulsive therapy (ECT) in Korea. This study investigated the practice pattern, effectiveness, and safety of ECT.
Methods: This chart review study included electronic medical records of 180 patients treated with ECT between January 2007 and December 2013 at the Asan Medical Center. Symptomatic improvement was assessed using Clinical Global Impression (CGI) scale. Treatment response was defined as CGI improvement scale score of 2 or less. Re-hospitalization was used as an indicator of recurrence. Safety was assessed by spontaneous reports from patients.
Results: One hundred and eighty patients underwent 1539 sessions of modified ECT. Their most frequent diagnosis was major depressive disorder (n=74, 41.1%). The most common indication for ECT was poor response to medication (n=177, 75.3%). Treatment response rate was 66.9% in acute phase group and 63.8% in the patients with poor response to medication. The recurrence rate at six months after the end of the course was 29.6%. Memory impairment or amnesia was the most common adverse effect.
Conclusion: There was a remarkable improvement following ECT in patients who responded poorly to medications, and most adverse effects were tolerable and temporary. The present study suggests that ECT could be a useful treatment option.
