This protocol describes a systematic scoping review of chronic respiratory disease surveys in low/middle-income countries (LMICs) undertaken as part of the Four Country ChrOnic Respiratory Disease (4CCORD) study within the National Institute for Health Research Global Health Research Unit on Respiratory Health (RESPIRE). Understanding the prevalence and burden of chronic respiratory disease (CRD) underpins healthcare planning. We will systematically scope the literature to identify existing strategies (definitions/questionnaires/diagnostics/outcomes) used in surveys of CRDs in adults in low-resource settings. We will search MEDLINE, EMBASE, ISI WoS, Global Health and WHO Global Health Library [search terms: prevalence AND CRD (COPD, asthma) AND LMICs, from 1995], and two reviewers will independently extract data from selected studies onto a piloted customised data extraction form. We will convene a workshop of the multidisciplinary 4CCORD research team with representatives from the RESPIRE partners (Bangladesh, India, Malaysia, Pakistan and Edinburgh) at which the findings of the scoping review will be presented, discussed and interpreted. The findings will inform a future RESPIRE 4CCORD study, which will estimate CRD burden in adults in Asian LMICs.

低/中等收入国家慢性呼吸道疾病调查方法的系统范围审查协议。


本议定书描述了对低/中等收入国家 (LMIC) 慢性呼吸道疾病调查的系统范围审查，作为国家卫生研究院全球健康呼吸健康研究单位四国慢性呼吸道疾病 (4CCORD) 研究的一部分（呼吸）。了解慢性呼吸道疾病 (CRD) 的患病率和负担是医疗保健规划的基础。我们将系统地界定文献范围，以确定资源匮乏地区成人 CRD 调查中使用的现有策略（定义/问卷/诊断/结果）。我们将搜索 MEDLINE、EMBASE、ISI WoS、Global Health 和 WHO Global Health Library [搜索术语：患病率 AND CRD（慢性阻塞性肺病、哮喘）和 LMIC，自 1995 年起]，两名审稿人将独立从选定的研究中提取数据到试点定制中数据提取表格。我们将召开多学科 4CCORD 研究团队与 RESPIRE 合作伙伴（孟加拉国、印度、马来西亚、巴基斯坦和爱丁堡）代表的研讨会，会上将介绍、讨论和解释范围界定审查的结果。这些发现将为未来的 RESPIRE 4CCORD 研究提供信息，该研究将估计亚洲中低收入国家成年人的 CRD 负担。
