CAT量表与稳定期COPD患者健康状态的关系

The COPD assessment test and the health status of COPD patients in stable stage

目的:探讨稳定期慢性阻塞性肺病(COPD)患者健康状态与CAT量表(COPD assessment test)的相关性。方法:采用横断面调查的方法,对104例稳定期COPD患者进行一般资料、CAT评分、Charlson合并症指数、mMRC评分的调查及6MWD和肺功能的检查,采用相关分析和回归分析。结果:CAT评分与FEV1%pred、6MWD、mMRC评分间均呈显著相关性(P<0.01)。逐步回归模型为:CAT评分=30.11+3.00×mMRC呼吸困难评分+0.002×急性加重频率-0.03×6MWD(r2=0.67,P<0.001)。结论:CAT量表可以客观真实地反映COPD患者的健康状态,急性加重频率严重影响患者的健康状态。

Objective：To explore the clinical application of the CAT scale in the evaluation of the health status of chronic obstructive pulmonary disease （COPD） patients in stable stage. Methods：A simple sampling survey of 104 cases of COPD patients in stable stage was enrolled. All participants were examined with CAT score, dyspnea index （mMRC）, 6-minute-walk test and pulmonary function test. Analysis on the correlation between CAT score and these test results was executed by Pearson correlation, and stepwise regression. Results：The associations between CAT score and FEV1%pred,6MWD,mMRC score were significant （P 〈 0.01）. Using stepwise regression, CAT score = 30.11 ＋ 3.00 ×mMRC dyspnoea score ＋ 0.002 × exacerbation -0.03 × 6MWD （r2 = 0.67,P 〈 0.001）. Conclusion： The CAT scale is reliable for the assessment of the quality of life and the frequency of exacerbations can seriously impact the patients＇ health status.
