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 diagnosis of chronic bronchitis to definitive diagnosis of COPD is long as well.
