Background:    

Sleep disturbance is a common but under-recognised feature of rheumatic diseases. It is important to recognise, as sleep disturbance has been demonstrated to impact function, mood, cognitive ability and morbidity. Patient reported outcome measures may help alert clinicians to sleep disturbance in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA).

Aims

To determine the prevalence of sleep disturbance in our cohort and to establish if this differs significantly between RA and PsA.

To examine the sensitivity and specificity of the sleep-disturbance components of the Multidimensional Health Assessment Questionnaire (MDHAQ) and the PROMIS 29 questionnaire to screen for significant sleep disturbance compared to the gold-standard PSQI questionnaire.

To determine the impact of co-morbid Fibromyalgia on self-reported sleep disturbance.

Methods:

This is a cross sectional observation study undertaken in the Rheumatology Outpatient Department of Liverpool Hospital, NSW, Australia. All patients attending the clinic were asked to complete the Multidimensional Health Assessment Questionnaire (MDHAQ), Patient Reported Outcome Measure Information System (PROMIS-29), Pittsburgh Sleep Quality Index (PSQI) and the Fibromyalgia Survey Questionnaire. Patients with a clinician diagnosis of Rheumatoid Arthritis or Psoriatic Arthritis were included in the study. Scores for the sleep disturbance component of the multidimensional questionnaires (MDHAQ and PROMIS-29) were compared to the scores on the PSQI. Patients were also stratified according to presence of fibromyalgia.

Results:

Among 159 study patients, 109 had rheumatoid arthritis and 50 had psoriatic arthritis. The median age of patients with Rheumatoid Arthritis was 59.1 years, and 78.9% were female. Of patients with Psoriatic Arthritis, the median age was 51.3 and 44.0% were female.

Sleep disturbance was present in in 77.1% of patients with Rheumatoid Arthritis, and 66.0% Psoriatic Arthritis, defined by a global PSQI score of > 5.

 

Further results will be presented at the meeting.
