- Aims: The aim of the present study is to investigate the rate of regained occupational functioning among patients treated with electroconvulsive therapy (ECT) for major depression and to define predictors of time to regained occupational functioning.Methods: A nested cohort study was performed of patients treated by ECT for unipolar major depressive disorder registered in the Quality register for ECT and in the Swedish Social Insurance Agency registry. Predictive values of single clinical variables and their relative importance were tested with Cox regression analysis.Results: 394 patients were identified. Of those, 266 were on non-permanent sick leave and 128 on disability pension during ECT. Within 1 year post-ECT, 71% of the patients with non-permanent sick leave regained occupational functioning. Factors independently associated with a statistically significant increased time to regained occupational functioning were longer duration of sick leave pre-ECT, milder depression pre-ECT, less complete improvement with ECT, benzodiazepine treatment after ECT and co-morbid substance dependence.Conclusions: A large proportion of the patients do not return to work within several months post-ECT. Paradoxically, patients with more severe depression pre-ECT had a reduced time to regained occupational functioning, indicating a larger effect in this patients group of the treatment. Moreover, the period with sick leave compensation might be reduced if ECT is initiated within the first 3 months of sick leave.Clinical implications: Most patients on non-permanent sick leave regain occupational functioning after ECT. However, it usually takes a few months even in symptomatically improved patients.

- OBJECTIVESThe 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).METHODSThis 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.RESULTSSubjective 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).CONCLUSIONSSubjective 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.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Journal article (peer-reviewed)abstract
- Objective Electroconvulsive therapy (ECT) is used in patients with severe forms of bipolar depression. ECT is effective but not all patients respond. The aim of this study was to determine prognostic factors for response to ECT in patients hospitalized for bipolar depression. Methods Data were obtained from several national Swedish registers. All patients with bipolar depression treated with ECT in any hospital in Sweden between 2011 and 2016 for whom information about ECT response was available were included (n = 1251). Response was defined as a score on the Clinical Global Impression - Improvement scale of one or two. Univariate and multivariate logistic regression were conducted to investigate associations between socio-demographic and clinical factors and response. Results Response was achieved in 80.2% patients. Older age was associated with higher response rate to ECT. Patients with comorbid obsessive-compulsive disorder or personality disorder, and patients previously treated with lamotrigine had lower response rate. Conclusion Electroconvulsive therapy for bipolar depression was associated with very high response rates. The strongest prognostic factors were higher age, absence of comorbid obsessive-compulsive disorder or personality disorder, and less prior pharmacologic treatment.

Journal article (peer-reviewed)abstract
- Background Electroconvulsive therapy (ECT) is effective in bipolar depression, but relapse is common. The aim of the study was (i) to identify prognostic factors (ii) and to determine the impact of pharmacological approaches on the risk for rehospitalization or suicide. Methods This register study analyzed data from individuals treated with inpatient ECT for bipolar depression. Subjects were identified using the Swedish National Patient Register between 2011 and 2014 and the Swedish National Quality Register for ECT. Other national registers provided data on psychopharmacotherapy, socio-demographic factors, and causes of death. The endpoint was the composite of rehospitalization for any psychiatric disorder, suicide attempt or completed suicide (RoS). Cox regression was used to calculate hazard ratios in univariate and multivariate models. Results Data from 1255 patients were analyzed. The mean period of follow-up was 346 days. A total of 29%, 41%, and 52% of patients reached RoS at 3, 6, and 12 months post-discharge. A history of multiple psychiatric admissions, lower age, and post-discharge treatment with antipsychotics or benzodiazepines was associated with RoS. Limitations Indication bias may have affected the results. Conclusions A history of multiple hospital admissions and lower age are key predictors of the composite of rehospitalization or suicide in patients treated with ECT for bipolar depression. Lithium might be effective. By contrast, antipsychotics and benzodiazepines were associated with increased risk, but possibly this finding was influenced by indication bias. © 2017 The Authors

Improvement of postpartum depression and psychosis after electroconvulsive therapy: A population-based study with a matched comparison group
- 2018
-
In: Journal of Affective Disorders. - : Elsevier BV. - 0165-0327 .- 1573-2517. ; 235, s. 258-264
-
Journal article (peer-reviewed)abstract
- Introduction: Electroconvulsive therapy (ECT) is used to treat postpartum depression and psychosis based on clinical experience and small observational studies. Aims: The primary aim was to test the hypothesis that the response rate to ECT for depression and psychosis is higher during the postpartum period than outside this period. The secondary aim was to identify predictors of a response to ECT during the postpartum period. Materials and methods: Cases with postpartum depression and/or psychosis received ECT within 6 months of delivery. A matched comparison group with depression and/or psychosis (not within the postpartum period) was identified from the Swedish National Quality Register for ECT. The improvement 1 week after ECT was classified according to the Clinical Global Impressions Scale - Improvement scale (CGI-I) as responder (CGI-I score 1-2) or non-responder (CGI-I score 3-7). Results: 185 cases and 185 comparison group subjects were included (46% with psychosis in each groups). More cases (87.0%) than comparison group subjects (73.5%) responded to ECT (p = 0.001). Adjusted binary regression analysis revealed that more severe symptoms prior to treatment were the only statistically significant predictor of response. Conclusion: The response rate of those with postpartum depression and/or psychosis to ECT was high. The response rate of patients with psychosis or depression was higher during the postpartum period than outside it. This study supports the use of ECT for severe forms of postpartum depression and/or psychosis.

- 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.

Journal article (peer-reviewed)abstract
- OBJECTIVE: Although electroconvulsive therapy (ECT) is anti-suicidal, it is not known whether the presence of suicidal ideation (SI) at baseline predicts response and remission after ECT. The aim of the study was to analyze the impact of baseline SI on response and remission following ECT treatment in a large sample of patients with depression and to assess SI before and after ECT.METHODS: This population-based register study used data from the Swedish National Quality Register for ECT and the Swedish Patient Register. Patients aged 18 years or older who had received ECT for a unipolar or bipolar depressive episode between 2011 and 2018 were included in the study. SI was defined as a score of ≥ 4 on the last item of the Montgomery-Åsberg Depression Rating Scale - Self Assessment (MADRS-S). Using a logistic regression model, SI at baseline was used to predict response and remission following ECT, while controlling for depression severity, psychotic symptoms, presence of a comorbid personality disorder, age, sex, electrode position, unipolar or bipolar disorder, and number of previous suicide attempts at baseline.RESULTS: In patients who exhibited SI at baseline, 53.7% (N = 632) of cases showed a response to ECT, whereas 68.4% (N = 690) of patients without SI showed a response. In addition, 27.2% (N = 320) of cases with SI achieved remission, whereas 48.5% (N = 489) of cases without SI achieved remission. The odds of achieving response and remission for patients with SI were 0.75 and 0.58 times, respectively, those for patients without SI. Of the 1178 patients with pre-treatment SI, 75.64% (N = 891) exhibited no SI at the end of treatment. Moreover, in this subgroup, the presence of a personality disorder, higher MADRS-S-score, and younger age were associated with persistent SI.CONCLUSION: The presence of SI was associated with lower ECT response and remission rates. Nevertheless, depressive symptoms and SI were reduced in a large proportion of patients across both patient groups. Clinicians should be aware of the lower likelihood of achieving a successful outcome following ECT in younger patients who present with a non-psychotic depressive episode, SI, and (suspected) personality disorders. More research is warranted regarding if these patients can achieve similar or better results with other treatments.

Predictors of Treatment Response to Electroconvulsive Therapy in Schizophrenia : A Nationwide Registry-Based Study
- 2020
-
In: Schizophrenia Bulletin Open. - : Oxford University Press. - 2632-7899. ; 1:1
-
Journal article (peer-reviewed)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.
