Abstract: Background　Pulmonary function tests are key means for detecting respiratory diseases. The 13th Five-Year Plan on hygiene and healthcare （2016—2020） and Healthy China Action （2019—2030） plan issued by the State Council of the People's Republic of China proposed that pulmonary function tests shall be listed as the routine tests and pulmonary function detection capability in primary care shall be improved. However，according to relevant reports in 2002，pulmonary function tests have been used limitedly with regional imbalances in China. Objective　To investigate the application of pulmonary function tests in Guangdong Province，and problems that need to be improved in the process of development. Methods　This investigation was conducted in 2016. From 21 prefecture-level cities in Guangdong Province，771 hospitals（including 141 tertiary hospitals，327 secondary hospitals，137 primary hospitals and 166 ungraded hospitals ） were extracted，from which medical workers were selected to attend an on-site in-person interview by assistants of this project and medical consultant assistants qualified by uniform trainings. Results　 The investigation achieved a response rate of 100%. The results showed that pulmonary function tests had been implemented in 30.35%（234/771） of the hospitals，44.9% and 47.4% of which were secondary and tertiary hospitals. And the most widely implemented was pulmonary ventilation /perfusion test（100.0%），followed by bronchodilation test（79.1%），and bronchial provocation test（51.7%）. In terms of pulmonary ventilation /perfusion test，of the hospitals，64.5% often calibrated the spirometer，23.5% used the lower limit of normal for the FEV1/FVC ratio，58.1% used a five-level method（mild，moderate，moderate to severe，severe，very severe） to grade the test results，and 38.9% only printed the test data and graphics on the report sheet once. The workers performing pulmonary function tests in 43.3%（334/771） of the hospitals had received related trainings，82.6% and 17.4% of whom had received short-term training （1-5 days） and long-term training （1-3 months），respectively. Conclusion　The popularization rate of pulmonary function tests in Guangdong was low，with unbalanced development. Besides that，few primary care hospitals conducted such tests，and the types of tests carried out were also few. In addition，the methods used for pulmonary function tests，quality control，report format and interpretation of results were nonstandard. There is an urgent need to strengthen the standardized training for workers performing pulmonary function tests.

摘要： 背景　肺功能检查是呼吸系统疾病重要的检查手段之一，国务院在“十三五卫生与健康规划”和健康中国行动（2019—2030年）中均提出将肺功能检查纳入常规检查项目，并提高基层医疗机构的肺功能检查能力，但据2002年相关报道，肺功能在全国开展率低，发展不平衡。目的　了解广东省肺功能检查的应用现状及在发展过程中亟需改进的问题。方法　抽取2016年广东省内21个地级市不同级别的医疗机构771家，其中三级、二级、一级、未定级医院分别有141、327、137、166家，由课题科研助理和医学顾问助理组成的研究人员经过统一培训合格后亲自前往调查地点，对医务人员进行面对面访问。结果　771家医疗机构有效完成调查问卷，30.35%（234/771）的医院已开展肺功能检查，其中二、三级医院分别占44.9%、47.4%。开展项目主要有肺通气功能检查（100.0%）、支气管舒张试验（79.1%）、支气管激发试验（51.7%）。在通气功能检查方面：64.5%的医院经常对肺量计进行定标；23.5%的医院使用正常低限（LLN）为第1秒用力呼气末容积（FEV1）/用力肺活量（FVC）结果判断标准；58.1%的医院使用五分法进行结果分度评估；38.9%的医院仅在报告单上打印1次测试数据和图形。43.3%（334家）的医院肺功能工作人员曾参与肺功能相关培训，分别有82.6%和17.4%参与短期培训（1~5 d）和长期培训（1~3个月）。结论　广东省肺功能检查的普及率仍较低，开展仍不平衡，基层医院少，且开展项目单一。肺功能检查方法、质控、报告格式和结果解读均欠缺规范。肺功能从业人员亟待加强规范化培训。
