P059 Sleep and Fibromyalgia: Identifying and Managing Sleep Disorders.

Abstract

Abstract Introduction Little is known about the presentation and management of sleep problems in patients with fibromyalgia [FMS]. This pilot study aims to 1) characterise sleep/wake patterns and sleep disorders in participants with FMS, and 2) assess changes in sleep and FMS symptoms with individualised sleep disorder treatment. Methods Women with FMS were recruited from the Rheumatology Unit at The Queen Elizabeth Hospital, South Australia. Participants recorded their sleep and activity for two-weeks using an under-mattress sleep sensor (Withings), sleep diaries and a wrist accelerometer. Questionnaires included Berlin Sleep Questionnaire (OSA); Epworth Sleepiness Scale; Flinders Fatigue Scale; Restless Legs Syndrome (RLS) Screener, Sleep Condition Indicator, and Fibromyalgia Impact Questionnaire. Results Preliminary data from 7 women (aged 49.3±12.8years, BMI 30.9±7.8kg/m2, average pain duration 14.1±9.4 years) were investigated. Sleep efficiency was low (65.9%±11.9). Five women were ‘high-risk’ for a sleep disorder (3 RLS, 3 OSA, 3 insomnia, 3 circadian rhythm disorders). Two were ‘high-risk’ for >2 sleep disorders. Two women had delayed, and one had advanced, circadian rhythms. Average self-reported sleep time in ‘high-risk’ women was shorter than the two women not at risk (6.2±1.1 vs 7.8±0.4hours). (6.2±1.1 vs 7.8±0.4hours). Fatigue Scores exceeded those commonly observed for respondents living with a medical condition (25.2±2.4 vs. 20.4 + 6.2). Participants are currently undergoing sleep disorder treatments and preliminary results will be reported. Conclusion Identifying and managing sleep disorders, using cognitive behavioural therapy for insomnia and chronotherapeutic approaches may be an important therapeutic target for FMS patients to improve sleep quality, daytime functioning, and FMS symptoms.
