Abstract

Background: Sleep problems are common in patients with Chronic Obstructive Pulmonary Disease (COPD) but the validity of Patient Reported Outcome Measures (PROMs) that measure sleep dysfunction has not been evaluated. We have reviewed the literature to identify disease-specific and non-disease specific sleep PROMs that have been validated for use on COPD patients. The review also examined the psychometric properties of identified sleep outcome measures and extracted point and variability estimates of sleep instruments used in COPD studies. Methods: The online databases EMBASE, MEDLINE, PsycINFO and SCOPUS for all years to May 2014 were used to source articles for the review. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Criteria from the Medical Outcomes Trust Scientific Advisory Committee guidelines were used to evaluate the psychometric properties of all identified sleep PROMs. Results: One COPD-specific and six non-COPD specific sleep outcome measures were identified and 44 papers met the review selection criteria. We only identified one instrument, the COPD and Asthma Sleep Impact Scale that has been developed specifically for use in COPD populations. 90% of identified studies used one of two non-disease specific sleep scales; The Pittsburgh Sleep Quality Index and/or the Epworth Sleep Scale, although neither has been tested for reliability or validity on people with COPD. Conclusions: The results highlight the need for existing non-disease specific instruments to be validated in COPD populations and also the need for new disease-specific measures to assess the impact of sleep problems in COPD
