Abstract
BACKGROUND: Studies investigating mortality secondary to electroconvulsive therapy (ECT) are few.
AIMS: To assess the risk of mortality from natural and unnatural causes among ECT recipients compared with other psychiatric in-patients over a 25-year period.
METHOD: Register-based cohort study of all in-patients admitted to a psychiatric hospital from 1976 to 2000. Cause-specific mortality was analysed using log-linear Poisson regression.
RESULTS: There were 783 deceased in-patients who had received ECT compared with 5781 who had not. Patients who had received ECT had a lower overall mortality rate from natural causes (RR=0.82, 95% CI 0.74-0.90) but a slightly higher suicide rate (RR=1.20, 95% CI 0.99-1.47), especially within the first 7 days after the last ECT treatment (RR=4.82, 95% CI 2.12-10.95).
CONCLUSIONS: Further investigation of the effect of ECT on physical health and the observed increased suicide rate immediately following treatment are needed, although the last finding is likely to result from selection bias.
