筛查问卷在慢性阻塞性肺疾病早期诊断中的应用进展

慢性阻塞性肺疾病（chronic obstructive pulmonary disease,COPD）是最常见的呼吸系统疾病之一，是全球第三大死亡原因，在我国40岁以上人群中发病率高达13.7%，给患者和社会带来沉重负担。对于COPD患者，早期诊断和早期干预是最重要的管理策略。目前COPD确诊依赖于肺功能检查，但由于肺功能检查成本较高，基层医疗机构常存在仪器缺少、技术人员培训不足等局限性，此时筛查问卷成为有效的补充诊断手段。本文对目前临床应用的各种筛查问卷进行综述，总结其优势和不足，为后续本土问卷的设计提供参考。

Advance of early identification of screening questionnaire for chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD), which performed as one of the most common respiratory diseases, is the third leading cause of death globally. In China, the morbidity of COPD in patients over 40 years old is as high as 13.7%, accompany with a heavy burden on patients and society. For patients with COPD, early diagnosis and intervention is the most important processing strategy. Pulmonary function test (PFT) is deemed as the gold standard of COPD diagnosis at present. However, PFT doesn''t seem to work for the high cost, the lack of equipment, and insufficient training of technicians in primary care settings. Questionnaire is a better tool for screening. This paper reviews several questionnaires, and compares their advantages and disadvantages, in further to evaluate the complication value of existing questionnaires and provide reference for our own questionnaire design.
