兵团基层不同层级医疗机构的肺功能指标差异特征分析OA

Objective To investigate the characteristics of pulmonary function indicators among medical institutions at different levels and populations in the base areas of the production and construction corps,and analyze the influencing factors on pulmonary function indicators.Methods A total of 5596 patients from 23 medical institutions in the selected corps were enrolled as study subjects.Patients were divided into Hami area group(n=1555)and the Northern Xinjiang region group(n=4041)based on their geographic location.Demographic data,core pulmonary function parameters,and pulmonary function test results were collected.Statistical analyses including Pearson correlation analysis and multivariate analysis of variance were employed to compare pulmonary function differences among groups and assess the correlation between variables.Results The abnormal rate of small airway indicators in the brigade branch hospitals was significantly higher than that in the division-affiliated hospitals at 25%,50%,and 75%predicted values(P<0.001).The forced expiratory volume in 1 second(FEV1)and FEV1/forced vital capacity(FVC)in Northern Xinjiang region group were higher than those in Hami area group,while the lung volume FVC in Hami area group was greater(P<0.001).Age showed a negative correlation with FEV1(β=-0.109,P<0.001).Conclusion There were significant differences in pulmonary function indices and small airway abnormality rates among medical institutions at different levels of medical institutions at the grassroots level of the corps,with quality control status and age being key influencing factors for pulmonary function.
