ObjectiveTo systematically review the diagnostic value of common screening questionnaires for chronic obstructive pulmonary disease (COPD). MethodsThe Cochrane Library, Web of Science, PubMed, EMbase, CNKI, WanFang Data and VIP databases were electronically searched to collect diagnostic studies on the effectiveness of COPD screening questionnaires from inception to January 31 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies,then network meta-analysis was performed by using Meta-disc 1.4 and Stata 15.0 software. ResultsA total of 28 studies involving 4 screening questionnaires were included. The results of the network meta-analysis showed that, sensitivity sorting was CDQ17 > LFQ > COPD-PS4 > CDQ20 > COPD-SQ > COPD-PS5, the specificity sorting was COPD-SQ > COPD-PS5 > CDQ20 > CDQ17 > COPD-PS4 > LFQ. Subgroup analysis showed the sensitivity of CDQ17 and specificity of CDQ20 were the highest in China, the sensitivity of LFQ and specificity of COPD-PS5 were the highest in foreign countries. ConclusionCurrent evidence suggests that CDQ and LFQ have high sensitivity but poor specificity, while COPD-SQ and COPD-PS have strong specificity but poor sensitivity. In China, CDQ is recommended for screening of COPD patients. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
