[Expert consensus on diagnosis, treatment and prevention of allergic diseases(Part Ⅲ)].

As the third part of the expert consensus on allergic diseases, this article includes efficacy evaluation, characteristics of allergic diseases in special populations, social and economic burden, psychological problems and prevention. The efficacy evaluation methods include symptom score, quality of life score and drug score. Allergic diseases of special populations have unique clinical characteristics and need special attention. The social and economic burden of allergic diseases is becoming heavier, which requires more attention. The three-level prevention of pollinosis can be completed through the "five in one" prevention and control strategies such as local vegetation survey, airborne pollen monitoring, epidemiological survey, standardized training of grassroots medical personnel, science popularization and academic lectures, which is more comprehensive and perfect than the "four in one" treatment strategy.本文为共识的第三部分，主要内容包括疗效评价、特殊人群过敏性疾病特点、社会和经济负担、心理学问题及预防。疗效评价方法包括症状评分、生活质量评分和药物评分。特殊人群的过敏性疾病有独特的临床特点，需要特别关注。过敏性疾病带来的社会和经济负担越来越重，需要高度重视。花粉症的三级预防可以通过当地植被调研、气传花粉监测、流行病学调查、基层医务人员规范化培训、科普及学术大讲堂等“五位一体”防控策略来完成，比“四位一体”的治疗策略更全面、更完善。.
