Abstract

INTRODUCTION: Psychiatric disorders are common during pregnancy, affecting up to 16% of pregnant women. Severe depression and anxiety have significant negative effects on the health of both the mother and the developing fetus. Electroconvulsive therapy (ECT) is considered a treatment option for pregnant women with severe psychiatric disorders when other treatments have been ineffective or pose risks to the fetus. Knowledge of the safety and efficacy of ECT during pregnancy, however, remains limited.

METHODS: Data were obtained from nationwide registries of pregnant women in Sweden who received ECT for a severe psychiatric disorder from January 2008 to December 2021. ECT-related outcomes in pregnant women were compared by... (More)

INTRODUCTION: Psychiatric disorders are common during pregnancy, affecting up to 16% of pregnant women. Severe depression and anxiety have significant negative effects on the health of both the mother and the developing fetus. Electroconvulsive therapy (ECT) is considered a treatment option for pregnant women with severe psychiatric disorders when other treatments have been ineffective or pose risks to the fetus. Knowledge of the safety and efficacy of ECT during pregnancy, however, remains limited.

METHODS: Data were obtained from nationwide registries of pregnant women in Sweden who received ECT for a severe psychiatric disorder from January 2008 to December 2021. ECT-related outcomes in pregnant women were compared by propensity score matching with a group of non-pregnant women who also received ECT. Pregnancy-related outcomes were compared with two additional control groups: one consisting of the same group of women who did not receive ECT during another pregnancy and the other composed of pregnant women admitted to inpatient psychiatric care but who did not receive ECT, matched based on propensity score.

RESULTS: Ninety-five pregnant women received ECT during the study period, accounting for 97 pregnancies. The response rate to ECT in pregnant women (n = 54) was similar to the matched control group of non-pregnant women (74% vs. 65%; OR 1.61; 95% CI 0.79-3.27). Rates of adverse events related to ECT were similar to those in the control group. There were no pre-term births or severe adverse outcomes related to the pregnancy, that were close in time to ECT. Therefore, no adverse outcomes related to pregnancy and childbirth could be directly attributed to ECT. The likelihood of premature birth and a 5-min Apgar score <7 in the newborn were both significantly higher in the ECT group, compared with the matched non-ECT group (OR 2.33, 95% CI 1.15-4.73, p = 0.008, and OR 3.68, 95% CI 1.58-8.55, p < 0.001, respectively). By contrast, no significant differences were observed when women in the pregnant ECT group were compared with the same group lacking ECT during another pregnancy.

CONCLUSIONS: ECT was associated with a positive treatment response in pregnant women with severe psychiatric disorders. The response rate to ECT was similar in pregnant and non-pregnant women. Nevertheless, the risks of premature birth and of a slightly poorer condition in newborns were higher in women who did than did not receive ECT, emphasizing the need for increased attention to severe psychiatric disorders during pregnancy.
