- BACKGROUND: Electroconvulsive therapy (ECT) is effective for unipolar depression but relapse and suicide are significant challenges. Lithium could potentially lower these risks, but is used only in a minority of patients.AimsThis study quantifies the effect of lithium on risk of suicide and readmission and identifies factors that are associate with readmission and suicide.METHOD: This population-based register study used data from the Swedish National Quality Register for ECT and other Swedish national registers. Patients who have received ECT for unipolar depression as in-patients between 2011 and 2016 were followed until death, readmission to hospital or the termination of the study at the end of 2016. Cox regression was used to estimate hazard ratios (HR) of readmission and suicide in adjusted models.RESULTS: Out of 7350 patients, 56 died by suicide and 4203 were readmitted. Lithium was prescribed to 638 (9%) patients. Mean follow-up was 1.4 years. Lithium was significantly associated with lower risk of suicide (P = 0.014) and readmission (HR 0.84 95% CI 0.75-0.93). The number needed to be treated with lithium to prevent one readmission was 16. In addition, the following factors were statistically associated with suicide: male gender, being a widow, substance use disorder and a history of suicide attempts. Readmission was associated with young age, being divorced or unemployed, comorbid anxiety disorder, nonpsychotic depression, more severe symptoms before ECT, no improvement with ECT, not receiving continuation ECT or antidepressants, usage of antipsychotics, anxiolytics or benzodiazepines, severity of medication resistance and number of previous admissions.CONCLUSIONS: More patients could benefit from lithium treatment.

- Objectives: The aims of the present study were to describe the short-term rate of subjective memory worsening (SMW) and identify factors of importance for SMW in a large clinical sample treated for depression with electroconvulsive therapy (ECT).Methods: This register-based study included 1212 patients from the Swedish National Quality Register for ECT. Subjective memory worsening was defined as a 2-point worsening on the memory item of the Comprehensive Psychopathological Rating Scale from before to within 1 week after treatment. Associations between patient characteristics and treatment factors were examined using logistic regression.Results: Subjective memory worsening was experienced in 26%. It was more common in women than in men (31% vs 18%; P < 0.001) and more common in patients aged 18 to 39 years than in patients 65 years or older (32% vs 22%; P = 0.008). Patients with less subjective memory disturbances before ECT had a greater risk of SMW. Patients in remission after ECT had a lower risk of SMW. A brief pulse width stimulus gave higher risk of SMW compared with ultrabrief pulse (odds ratio, 1.61; 95% confidence interval, 1.05-2.47).Conclusions: Subjective memory worsening is reported by a minority of patients. However, young women are at risk of experiencing SMW. Ultrabrief pulse width stimulus could be considered for patients treated with unilateral electrode placement who experience SMW. Each patient should be monitored with regard to symptoms and adverse effects, and treatment should be adjusted on an individual basis to maximize the clinical effect and with efforts to minimize the cognitive adverse effects.

- OBJECTIVES: Electroconvulsive therapy (ECT) is used in some cases of postpartum depression (PPD) and postpartum psychosis (PPP). The risk of relapse for PPD and PPP after ECT is unknown. This study compared the relapse rate after ECT between women who had been treated for PPD and/or PPP and women who had been treated for depression and/or psychosis outside the postpartum period.METHODS: The Swedish National Quality Register for ECT and the Swedish National Patient Register were used to identify women with PPD and/or PPP who had been treated with ECT within 6 months after delivery. For each case, a control (treated with ECT but not postpartum) patient was also selected. A Kaplan-Meier estimator was used to calculate the relapse rate (defined as rehospitalization or suicide) after ECT. Cox regression was used to identify variables associated with relapse.RESULTS: A total of 180 patients were included in each group. The proportions of patients who suffered relapse after 6 months, 1 year, and 2 years were 28%, 31%, and 40% for the postpartum group and 39%, 50%, and 55% for the nonpostpartum group. Treatment with benzodiazepines, several previous psychiatric admissions, and the absence of improvement after ECT were associated with relapse.CONCLUSIONS: The risk of relapse after ECT is lower for patients with PPD and/or PPP than for patients outside the postpartum period, but the risk is nonetheless substantial in both groups.

Predictors of Treatment Response to Electroconvulsive Therapy in Schizophrenia : A Nationwide Registry-Based Study

Tidskriftsartikel (refereegranskat)abstract
- Up to 30% of patients with schizophrenia respond insufficiently to antipsychotic drugs. Electroconvulsive therapy (ECT) has been reported to effectively augment the effects of antipsychotics in some of these patients. To date, there are few established predictors of treatment response to ECT in patients with schizophrenia. The primary aim was to determine the response rate to ECT in patients with schizophrenia. The secondary aim was to investigate predictors of treatment response. All patients admitted to any Swedish hospital for schizophrenia from 2011 to 2017, who were treated with ECT while in inpatient care, were included in the Swedish National Quality Registry for ECT (Q-ECT), and were assessed using the Clinical Global Impression – Improvement (CGI-I) scale after treatment were included. CGI-I scores of 1 or 2 were considered a response to treatment. Multiple national registries were used to obtain information on demographics and clinical variables. The study included 285 patients who were concurrently treated with antipsychotic drugs. The response rate to ECT was 73.0%. Among those patients with outcome data, treatment with long-acting injectable antipsychotics was predictive of a better response, whereas comorbid substance use disorders were predictive of a worse response. This study provides new evidence on predictors of who might respond among patients with schizophrenia treated by ECT. Additional studies of ECT in schizophrenia are needed.
