Abstract

Abstract : Introduction: A considerable number of insomnia patients experience sleep disturbance even with long-term use of hypnotic medication. Previous studies have indicated that electroacupuncture (EA) could be an efficacious treatment for managing insomnia. However, few trials have been conducted to evaluate the effectiveness and safety of EA for treatment-resistant insomnia. This pilot study aims to explore the feasibility and preliminary effectiveness and safety of EA as an adjunct treatment for treatment-resistant insomnia. Methods and analysis: This is a multicentre, randomised, usual care controlled and assessor-blinded pilot study protocol. Fifty patients presenting with sleep problems who have been taking hypnotic medication for more than 3 months will be randomly allocated to either an EA group or a usual care group at a 1:1 ratio. The EA group will undergo 12 EA treatment sessions twice a week for 6 weeks whereas the usual care group will not receive EA treatment. All the participants will receive a brochure containing educational information on sleep hygiene. The primary outcome will be the measured mean change of the total score of the Insomnia Severity Index from the baseline to week 7. The secondary outcome regarding sleep quality will be measured using the Pittsburgh Sleep Quality Index, a sleep diary and actigraphy. Moreover, we will assess the quality of life, the direct and indirect cost of treating insomnia for economic evaluation. After 4 weeks, the subjects will visit the research sites for a follow-up assessment. Ethics and dissemination: Ethical approval of this study protocol was established by the institutional review boards of the each involved study site. All potential subjects will be provided written informed consent. The results of this study will be accessible in peer-reviewed publications and be presented at academic conference. Trial registration number: KCT0003235.
