摘要
[目的]为了科学、合理地指导家用水质处理器在日常使用中的管理和维护,对家用水质处理器使用中的相关卫生状况指标进行筛选。[方法]采用改良德尔菲法,在收集文献资料的基础上,结合上海市家用水质处理器使用过程中的污染特点形成第一轮指标咨询表,以此对该市相关领域22位专家进行咨询,并根据咨询专家反馈的评分和意见加以调整,然后再次征询,待专家意见趋于一致时终止咨询,形成结果。[结果]经统计处理,两轮咨询表的积极系数均为100%,专家权威程度分别为0.80和0.81。第一轮的协调系数W=0.174(χ2=6.39,P>0.05),第二轮的协调系数W=0.835(χ2=19.89,0.05<P<0.10),形成的14项家用水质处理器卫生指标得到专家们的基本肯定,一致性相对较好。[结论]采用德尔菲法筛选监管家用水质处理器的卫生评价指标,方法可行。结果可纳入到最终评价家用水质处理器的卫生管理要求中,并应用于家用水质处理器日常使用的指导和管理之中。
[ Objective ] To sift through the hygienic indicators for better guidance in management and maintenance of household water purify systems. [ Methods ] The improved Delphi method was adopted to screen indicators. The first-round consultation form was based on literature review and pollution characteristics of household water purify systems in Shanghai. Twenty-two experts from relevant fields were invited to the consultation. The form content was adjusted according to the feedbacks and delivered to the experts again. Consultation stopped when experts reached a consensus. [ Results ] The responding rates of the 2 consultation rounds were both 100%, and the authoritative coefficients of experts were 0.80 and 0.81, respectively. The coordination coefficient of the first round was 0. 174 （X2= 6.39, P 〉 0.05）, and the final coordination coefficient was 0.835 （X2=19.89, 0.05 〈P〈0.10）. The concentration degree of engaged experts＇ views and the consensus for 14 indicators were considered at a high level. [ Conclusion ] The Delphi method is feasible to screen hygienic indicators for household water purify systems and the indicators obtained are acceptable in hygiene evaluation and daily management.
