【摘要】 目的探讨建立区域性大型活动卫生保障餐饮安全、公共场所、饮用水卫生综合性风险评价指标体系,为开展区域性大型活动卫生保障工作提供科学依据。方法选择30名专家进行两轮Delphi专家咨询,根据指标重要性赋值得分,确定餐饮安全、公共场所、饮用水卫生综合性风险评价的指标及其权重。结果 30名咨询专家的平均工龄为(20.63±5.80)a,两轮的应答率均为100%,权威系数分别为0.86±0.06、0.89±0.06,Kendall协调系数分别为0.807(χ2=1 858.758,P<0.01)、0.869(χ2=2 018.723,P<0.01),确定了餐饮安全、公共场所、饮用水卫生综合性风险评价指标一级指标3项,二级指标13项,三级指标54项,以及各项指标的权重。其中餐饮安全的二级指标5项,三级指标22项;公共场所的二级指标5项、三级指标22项;饮用水卫生的二级指标3项,三级指标10项。餐饮安全、公共场所、饮用水卫生的平均权重分别为5.37,2.54,2.09。结论 Delphi专家咨询法是构建区域性大型活动卫生保障餐饮安全、公共场所、饮用水卫生综合性风险评价指标体系的有效方法,并将为进一步建立风险评价方法奠定基础。更多还原

【Abstract】 [Objective]To discuss the establishment of comprehensive risk assessment index system for catering food safety,public places and drinking water sanitary during the regional large-scale activities,and provide scientific evidence for its health security.[Methods]A 2-round Delphi consultation was held to choose suitable indicators and their weights of the comprehensive risk assessment for catering food safety,public places and drinking water sanitary during the regional large-scale activities by 30 experts.The suitable indicators were selected according to the importance recognized by the experts.[Results] The average length of service of the 30 experts was(20.63±5.80) years.And the response rates of the 2-round consultation from the experts were both 100%,the average coefficient of experts’ authorities were 0.86±0.06 and 0.89±0.06 respectively.And Kendall’ s coefficient were 0.807(χ2=1 858.758,P<0.01)and 0.869(χ2=2 018.723,P<0.01) respectively.Three first-class indicators,13 second-class indicators and 54 third-class indicators for comprehensive risk assessment of catering food safety,public places and drinking water sanitary were identified.And the weight of the indicator was established.Among which,5 second-class indicators and 22 third-class indicators for food safety,5 second-class indicators and 22 third-class indicators for public places and 3 second-class indicators and 10 third-class indicators for drinking water sanitary were identified.Moreover,the average weight of catering food safety,public places and drinking water sanitary were 5.37,2.54 and 2.09,respectively.[Conclusion]Delphi method is an effective method to establish the comprehensive risk assessment index system for catering food safety,public places and drinking water sanitary during the regional large-scale activities.Furthermore,it will lay the foundation of the establishment of comprehensive risk assessment method更多还原
