Abstract

Objectives: The aims of this naturalistic study are to examine psychiatric rehospitalization rates in geriatric compared to nongeriatric patients who receive electroconvulsive therapy (ECT) and to characterize the sustained effectiveness of ECT for treatment of depression. Methods: Retrospective review of electronic medical records at a tertiary care center for patients with major depressive disorder who received an acute course of ECT at an index psychiatric hospitalization over a 5-year period. Data for subsequent psychiatric and primary care encounters were ascertained by chart review. Outcomes of interest included betweengroup differences in rates of psychiatric rehospitalization, time to rehospitalization, rates of other types of clinical follow-up care, and effect of demographic variables on clinical outcome. Results: Of 482 total patients, there were 210 (44%) geriatric patients (≥65 years). These patients experienced lower overall rates of psychiatric rehospitalization after ECT (6.2% vs 22%; P < 0.0001) compared to the nongeriatric group. Cox proportional hazard models indicated that older age, assessed both as a dichotomous and continuous variable, was associated with lower risk of rehospitalization. The majority (76.9%) of detected rehospitalizations among geriatric patients occurred within 6 months. In comparison, rates of outpatient primary care and psychiatric follow-up after ECT did not differ as a function of age. Conclusions: Our findings suggest that geriatric patients with major depression receive greater long-term benefit from an acute course of ECT than do nongeriatric patients. Much more research is needed on this topic to rigorously evaluate the long-termefficacy of ECTin geriatric populations.
