慢性阻塞性肺疾病常见证候要素对应症状的专家问卷调查研究

Expert questionnaire on corresponding symptoms to common syndrome factors of chronic obstructive pulmonary disease

目的运用专家问卷调查的方法初步确定慢性阻塞性肺疾病常见中医证候要素的主要对应症状。方法在前期研究结果的基础上,制订专家问卷,对全国8个省市20家医院及科研院所从事呼吸系统疾病工作的专家进行调查。问卷回收后,建立Epidata 3.1数据库管理数据,运用SPSS17.0统计软件分析数据,在分析专家对常见证候要素对应症状重要性程度评价的变异系数、均数、累积百分比的基础上,确定常见证候要素的主要对应症状。结果本次调查共发放问卷89份,收回89份,回收率为100%,均为有效问卷。根据专家对症状重要性程度评价情况及专家意见的集中程度、协调程度情况,将累积百分比≥70%和变异系数≤0.40作为确定常见证候要素主要对应症状的原则,初步确定慢性阻塞性肺疾病常见病位类证候要素主要对应症状24个,常见病性类证候要素主要对应症状79个。结论通过专家问卷调查,初步确定了慢性阻塞性肺疾病常见证候要素主要的对应症状,为进一步建立该疾病基于证候要素的辨证标准提供了依据。

Objective To determine initially the main corresponding symptoms to common TCM syndrome factors of chronic obstructive pulmonary disease （COPD） by using expert questionnaire. Methods On the base of previous research, an expert questionnaire was designed and with which a survey was carried out in the experts working in treatment of respiratory system diseases from 20 hospitals and institutes in 8 cities and provinces in the whole country. After the questionnaires were taken back, and the data were managed with Epidata3.1 database and analyzed by using SPSS17.0 statistical soltware. The coefficient of variation, mean value and cumulative percentage were analyzed alter the experts reviewed the importance of main corresponding symptoms to common TCM syndrome factors of COPD, and main corresponding symptoms were determined. Results The survey sent out 89 questionnaires and took back 96 that were all effective ones. The callback rate was 100%. According to the review on symptom importance by experts and concentration and coordination of their opinions, cumulative percentage being more than 75% and coefficient of variation being less or equal 0.40 were taken as the principle for determining the main corresponding symptoms to common TCM syndrome factors. There were 24 corresponding symptoms of syndrome factors related to disease locations and 79 related to diseases nature determined initially. Conclusion The main corresponding symptoms to common TCM syndrome factors of COPD were confirmed by expert questionnaire, which will provide the evidence for establishing TCM syndrome factor-based diagnosis criteria of COPD.
