P160: Electroconvulsive therapy for neuropsychiatric symptoms in dementia: survey among Dutch physicians

Objective:Neuropsychiatric symptoms (NPS) are common in people with dementia and have a negative effect. Commonly used pharmacological and psychosocial interventions are not always effective and NPS can become refractory. Electroconvulsive therapy (ECT) may be effective for (severe) agitation and aggression and is well tolerated. Nevertheless, its application seems limited in the Netherlands. We explored the application of and attitudes of physicians towards ECT for (severe) NPS in older people with dementia in the Netherlands.Methods:A survey study among geriatricians, elderly care physicians and old-age psychiatrists in the Netherlands in July 2020. An online invitation was included in the digital newsletter of the professional society or directly sent to the professional network of one of the authors (in case of old-age psychiatrists). The questionnaire included 20 closed- and open ended questions on demographic characteristics, experiences with (consideration of) referral for/application of ECT and attitudes towards ECT.Results:Sixty-one respondents completed the survey, eight had ever considered ECT. Two of these eight referred patient(s) for depressive behavior, sometimes combined with agitation. Lack of experience, ECT not being included in guidelines for this indication, unfamiliarity with possible (side) effects and risks, ethical and practical issues were the main reasons of the respondents for not considering ECT. Most respondents were open to referring patients with dementia for ECT to treat (severe) NPS, specifically in case of refractory symptoms.Conclusion:Respondents are not negative about ECT, yet rarely consider it due to lack of awareness and knowledge and the ethical and practical issues related to its application. Although the response to our survey was low and the number of respondents is limited, we do feel that ECT may be an alternative for palliative sedation, which is used incidentally in cases of refractory NPS in the Netherlands. Further exploring the support base and possibilities for application of ECT-treatment for refractory NPS might therefore be worthwhile.
