Chronic obstructive pulmonary disease (COPD) is a major health burden worldwide. Reasons for poor management include lack of awareness regarding COPD among healthcare providers and patients, insufficient use of diagnostic tests (such as spirometry), poor treatment decisions. Another major issue is poor doctor-patient communication which can lead to inaccurate assessment of a patient's clinical picture. The COPD Assessment Test (CAT) is a clinical tool which provides a quantitative measure of the severity of a patient's symptoms and their pulmonary health status. It is a brief patient-filled questionnaire that only takes a few minutes to fill out. This has the potential to help bridge deficiencies in the clinical history that may be left by any communication gap between the patient and the physician. Various studies have investigated the effectiveness of CAT in clinical settings. Herein we review these studies to examine the sensitivity, validity and reliability of the CAT as a clinical diagnostic and assessment tool in light of the existing literature.
慢性阻塞性肺疾病（COPD）是全球范围内的一个主要健康负担。管理不善的原因包括医疗保健提供者和患者对 COPD 的认识不足，诊断测试（如肺活量测定）使用不足，治疗决策不当。另一个主要问题是医患沟通不畅，这可能导致对患者临床情况的评估不准确。COPD 评估测试（CAT）是一种临床工具，可对患者症状的严重程度及其肺部健康状况进行定量评估。它是一份简短的患者填写的问卷，仅需几分钟即可填写完毕。这有可能有助于弥补患者与医生之间任何沟通差距可能导致的临床病史中的不足。多项研究已经调查了 CAT 在临床环境中的有效性。在此，我们回顾这些研究，以根据现有文献，检查 CAT 作为临床诊断和评估工具的敏感性、有效性和可靠性。
