辽宁省肺功能检查普及情况及COPD 患者对肺功能检查认知情况的调查分析

 目的了解肺功能检查（PFT）在辽宁省的普及情况及慢性阻塞性肺疾病（COPD）患者对肺功能检查的认知情况。方
法对辽宁省内129 家二级及以上综合性医院肺功能检查的普及情况电话及直接问卷调查。对206 例COPD患者进行肺功能
检查认知状况横断面调查。结果开展肺功能检查的医院占总数的51.2豫，肺功能检查在三级医院中的普及率高于二级医院，
分别为79.4%和24.2%。在206 例COPD患者中曾诊断过COPD 者53 例（25.73%），既往做过肺功能者100 例（48.5%）。在诊断
过慢性支气管炎的患者中曾被诊断为COPD 者仅33.8%，其确诊COPD 的时间是在慢性支气管炎诊断后的（11.79±10.96）年，且
诊断COPD 时多数患者已为Ⅲ、Ⅳ级。结论辽宁省肺功能检查的普及率偏低，尤其是二级综合性医院。慢性支气管炎患者进
行肺功能检查的比率低，COPD 的确诊时间晚。

Investigation of the Prevalence of Pulmonary Function Test in Liaoning Province and the Cognition of COPD Patients to the Test

Objective To survey the prevalence of the pulmonary function test in Liaoning province and investigate the cognition of chronic
obstructive pulmonary disease （COPD）patients to the test. Methods One hundred and twenty nine comprehensive hospitals of Grade
Three and Grade Two have been included to survey the prevalence of the pulmonary function test by telephone. A cross-sectional study was
carried out among 206 COPD outpatients to investigate their cognition to the pulmonary function test. Results The total prevalence of the
hospitals with the equipment and ability to do pulmonary function tests was only 51.2%. The prevalence of the hospitals of Grade Three
（79.4%）was higher than that of the hospitals of Grade Two（24.2%）. In 206 COPD patients，100 cases（48.5%）had been provided with
pulmonary function test，53 cases （25.73%）had been diagnosed as COPD in the past. The patients diagnosed as COPD accounted for
33.8% of all chronic bronchitis patients surveyed. The span during the diagnosis of chronic bronchitis and the definitive diagnosis of COPD
was 11.79±10.96 years. Conclusion The prevalence of pulmonary function test in Liaoning province is relatively low，especially in the
comprehensive hospitals of Grade Two. Few chronic bronchitis patients received pulmonary function test. Thus the time span from the diag-
nosis of chronic bronchitis to definitive diagnosis of COPD is long as well.
