Abstract

BACKGROUND: Pain is emerging as a clinical complication in COPD, but the clinical impact of this comorbidity and the measurement properties of instruments used to assess pain require evaluation. METHODS: Electronic searches of fi ve databases were performed up to September 2014 for the two phases of this review. To be included in phase 1, studies reported the clinical associations of pain and prevalence in individuals with COPD. To be included in phase 2, studies reported measurement properties of an instrument assessing pain in COPD. Two independent reviewers rated the quality of quantitative and qualitative evidence (phase 1) and the measurement properties using the four-point Consensus]Based Standards for the Selection of Health Status Measurement Instruments (COSMIN) checklist (phase 2). RESULTS: Of the 358 studies identifi ed in the literature, nine met the inclusion criteria for phase 1 and fi ve for phase 2. Th e mean (SD) quality score (of 16) for the quantitative studies was 13.1 (1.7). Th e pooled prevalence of pain in moderate to very severe COPD was 66% (95% CI, 44%-85%). Higher pain intensity was associated with increased dyspnea, fatigue, poorer quality of life, and a greater quantity of specifi c comorbidities. Of the two identifi ed instruments (Brief Pain Inventory and McGill Pain Questionnaire), the measurement properties analyzed were construct validity, internal consistency, and criterion-predictive validity, with variable fi ndings based on gfairh or gpoorh quality studies. CONCLUSIONS: In people with COPD, pain has negative clinical associations with symptoms and quality-of-life measures. Further research exploring the measurement properties of instruments assessing pain is required.
