摘要:
目的 探讨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方法,为大型活动接待单位的事先遴选和开展卫生保障工作提供科学依据。 方法 采用Delphi专家咨询法研究确定餐饮安全、公共场所、饮用水卫生综合性风险评价指标体系及其权重;采用综合指数法建立线性综合评价模型。 结果 30名咨询专家的平均工龄为(20.63& #177;5.80)年,两轮的应答率均为100%,权威系数分别为0.86& #177;0.06、0.89& #177;0.06,Kendall协调系数分别为0.807(χ2=1858.758,P<0.01)、0.869(χ2=2018.723,P<0.01),经卡方检验均具有统计学意义;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、公共场所和饮用水卫生的平均权重分别为5.37、2.54、2.09;并建立了线性综合风险评价模型。 结论 大型活动卫生保障餐饮安全、公共场所和饮用水卫生线性综合风险评价模型的建立,将为大型活动接待单位的事先遴选和开展卫生保障工作提供科学依据,具有推广应用价值。 Abstract:Objective To discuss integrated quantitative risk evaluation of the safety of catering food, public places and drinking water in large-scale events in order to provide scientific basis for the selection of reception units as well as the work of hygiene security. Methods Delphi expert consultation method was used to establish the indicator system of the integrated risk evaluation of catering food, public place and drinking water safety, and to determine the weight of the indicators. Integrated index method was used to establish linear integrated risk evaluation model. Results The average length of service of the 30 experts was (20.63& #177;5.80) years. In two rounds of consultations, their response rates were both 100%, the average authoritative coefficients were 0.86& #177;0.06 and 0.89& #177;0.06, and Kendall's coefficient were 0.807 (χ2=1858.758, P<0.01) and 0.869 (χ2=2018.723, P<0.01). A total of 3 primary, 13 secondary and 54 tertiary indicators for integrated risk assessment were identified. Their weights were measured, and that of catering food, public place and drinking water hygiene were 5.37, 2.54 and 2.09, respectively. A linear integrated risk evaluation model was established. Conclusion The linear integrated risk evaluation model of catering food, public place and drinking water hygienic security in largescale events can provide scientific evidence and technical support for the security of public health and the selection of reception units.
