基于百度指数的公众对慢性阻塞性肺疾病的关注情况分析

Public awareness for chronic obstructive pulmonary disease based on Baidu Index

目的通过分析公众及媒体对“慢性阻塞性肺疾病”网络关注的习惯及特点,了解及探讨目前国内慢性阻塞性肺疾病(COPD)低公众知晓率的原因。方法以2011年1月1日到2018年12月31日为时间范畴,使用百度指数大数据分析工具,以“慢阻肺”、“慢性阻塞性肺疾病”、“肺气肿”、“慢性支气管炎”、“COPD”为5个关键词,以“周”为时间单位记录“搜索指数”和“媒体指数”数据,季度汇总,产生数据并进行二次分析。结果8年间,公众对COPD的关注度还是在逐渐增加的,但在与COPD相关的5个相关关键词中,公众更多选择“肺气肿”作为检索关键词,搜索指数的累计增长绝对值最高,且“肺气肿”在各年度的搜索指数均高于其余4个关键词(P<0.001);媒体对于COPD的关注度逐年降低且与公众关注不同的是,媒体指数中是关键词“慢阻肺”显著高于其他各关键词(P<0.001)。结论为改善公众和COPD患者对于COPD的疾病认知,临床医务工作者应在患者教育及疾病宣传过程中阐明“慢阻肺”和“肺气肿”、“慢性支气管炎”的关系;还应强化媒体对于疾病信息的正确传递。

Objective Through analyzing the habits and characteristics of the public and the media on the network of chronic obstructive pulmonary disease(COPD),this paper aims to realize and explore the reasons for the low public awareness rate of COPD in China.Methods Taking the period from January 1,2011 to December 31,2018 as the time range into consideration,we used the big data analysis tool of Baidu Index and took“chronic bronchitis and emphysema”,“chronic obstructive pulmonary disease”,“emphysema”,“chronic bronchitis”and“COPD”as the five key words,as well as took“week”as the measuring unit of time to record the“search index”and“media index”data,and all information were summarized quarterly to generate the final data which was carried out for secondary analysis.Results During the past eight years,the public′s attention on COPD had been increasing gradually.However,among the five key words related to COPD,the public preferred to choose“emphysema”as the key word for web searching,and the absolute value of cumulative growth for the search index was on the highest level.And the“emphysema”in the search index was higher than the other four key words(P<0.001)in each year.The media′s attention on chronic bronchitis and emphysema had been declining year by year.The key words"chronic bronchitis"and"emphysema"in the media index were significantly higher than the other key words(P<0.001).Conclusion In order to improve the COPD cognitive awareness of the public and the patients,the clinical medical workers should clarify the relationship among the key words of“COPD”,“emphysema”and“chronic bronchitis”in the process of the patient education and disease information.Meanwhile,the media should be strengthened to deliver disease information correctly.
