A survey on the correlation between patients'cognition with COPD caused by occupational exposure and the control of the disease
Objective The survey was designed to find,in Chinese cities,how well chronic obstructive pulmonary disease(COPD)is controlled and how the patients perceive it as a result of occupational exposure.Toprovide an analysis into the correlation between patients'cognition with COPD and the control of the disease in a way to provide the theoretical basis for better controlling the disease.Methods A total of 192 COPD patients were surveyed face-to-face in the form of questionnaire from January 2020 to June 2021.They were from three hospitals in Jinan,including a tertiary general hospital,a tertiary occupational hospital and a secondary general hospitalrespectively.Results Among the surveyed,98casesin the occupational exposure group,taking up 51％of the total;94cases in the non-occupational exposure group,taking up 49％.The effectiveness of COPD control was measured by two dimensions,one was the mMRC classification(0,1,2,3,4)which used to assess the difficulty of breathing,another was the COPD grouping(A,B,C,D)which used to assess the severity of the disease according to the guidelines in GOLD 2020 Report.Question 1 is that what COPDis.In the COPD assessment grouping,it was found that the constituent ratio of respondents who answered correctly was lower than that ofincorrect answer groupwithsignificantly difference(x2=12.582,P＜0.05).Question 2 aboutwhich is preferredin the treatment of acute COPD patients advised to use bronchodilators regularly on a daily basis?To only use a short-acting bronchodilator like ventolin or to use together with short-acting anticholinergic like ipratropium bromide.In the mMRC classification,it was found that the constituent ratio of respondents who answered correctlywas lower than that of incorrect answer group,with significantly difference(x2=18.471,P＜0.05).There were significant differences between the occupational exposure group and non-occupational exposure group in the question 5 about whether COPD caused by occupational irritant chemicals is a legal occupational disease,x2=8.265,P＜0.05.Conclusion The awareness rate of COPD is low in the patients.The patients have a serious lack of disease-related cognition of COPD caused by occupational exposure,and the disease control level is poor.Strengthening universal education of knowledge of COPD and occupational exposure,factors,to improve the overall disease control level of COPD.
