Dyspnoea and pain are symptoms of chronic obstructive pulmonary disease (COPD). This review focused upon pain and dyspnoea during hospital admissions for acute exacerbations of COPD (AECOPD), with the aim of examining prevalence, assessment, clinical associations, and researcher-reported implications of these symptoms. Four electronic databases were searched from inception to 31 May 2021. Full text versions of studies were assessed for methodological quality and data were extracted independently by two reviewers. Where data permitted, pooled prevalence of pain and dyspnoea were calculated by meta-analysis. Four studies were included. The pooled prevalence of pain and dyspnoea was 44% (95% confidence interval (CI) 35%-52%) and 91% (95% CI 87%-94%) respectively. An array of instruments with varying focal periods were reported (pain: six tools, dyspnoea: four tools). Associations and clinical implications between the two symptoms at the time of hospital admission were rarely reported. Few studies reported prevalence of pain and dyspnoea during an AECOPD. A greater understanding into the prevalence, intensity and associations of these symptoms during AECOPD could be furthered by use of standardised assessment tools with clearly defined focal periods. |
