PURPOSE: To evaluate and compare sleep quality in Rheumatoid Arthritis (RA) and Osteoarthritis (OA) patient populations.

METHODS: Consecutive RA and OA clinic patients were invited to participate in a self-administered questionnaire study which included the multi-domanin Pittsburgh Sleep Quality Index (PSQI), visual analogue scales for pain, fatigue, global functioning, modified Health Assessment Questionnaire (mHAQ), stress scores, the Centre for Epidemiologic Sudies-Depression (CES-D) score, the SF-36 quality of life measure, the Rheumatoid, Arthritis, Disease Activity Index (RADAI), the Berlin score for Obstructive Sleep Apnea (OSA) risk, and the International Restless Legs Syndrome Study Group (IRLSSG) diagnostic criteria.

RESULTS: No significant differences in PSQI global or domain scores were observed between patient groups. PSQI global scores were abnormal in 62% of 145 RA and 67% of 78 OA patients. Increased abnormalities in sleep assessment, sleep latency, sleep duration, sleep efficiency, daytime dysfunction and increased sleep aid medication use were observed in both populations. The most frequent abnormality reported was increased cumulative sleep disturbances in 44% of RA and 53% of OA patients. In RA patients the CES-D and global function scores were independent predictors for an abnormal PSQI global score. IRLSSG criteria were met by 27% of RA and 22% OA patients. 39% RA and 38% OA patients were high risk for OSA.

CONCLUSION: A high prevalence of abnormal sleep quality in both RA and OA patient populations was observed. The most common sleep abnormality was an increased cumulative sleep disturbance score. An increased prevalence of possible primary sleep disorders was also found.

CLINICAL IMPLICATIONS: Sleep quality abnormalities are common and may be clinically underestimated in rheumatic disease patients. Increased screening for sleep disturbances is suggested in the rheumatoid arthritis and osteoarthritis patient populations.
