摘　　要：目的建立Kato-Katz法检测土源性线虫病现场评价体系,为Kato-Katz法的现场应用提供参考。方法通过文献查询、头脑风暴法和专家咨询法初步确定Kato-Katz法检测土源性线虫病现场评价指标体系;采用专家咨询法,通过3轮专家咨询完善评价指标体系并计算各指标权重,同时计算各轮专家咨询各指标的专家权威系数和协调系数。结果3轮专家咨询的问卷回收率分别为100.00%、100.00%和89.29%,各指标专家权威系数均>0.85。最终确定了包含4个一级指标和15个二级指标的评价体系。一级指标中"检测效果"和"投入经费"的加权均值分别为4.53和4.49,相对高于"投入人时"和"可操作性"(加权均值均为4.34);二级指标按重要性大小排序依次为"检测人员虫卵形态鉴别能力"、"村干部和村医配合度"、"检测人时"和"组织发动费用",其加权均值分别为4.74、4.43、4.39和4.17。第1~3轮专家咨询各指标协调系数范围分别为0.39~0.65、0.28~0.58和0.45~0.65,且3轮专家咨询各指标协调系数差异均有统计学意义(P均<0.05)。结论本研究建立了Kato-Katz法检测土源性线虫病现场评价体系。在该指标体系中,"检测人员虫卵形态鉴别能力"和"村干部和村医配合度"重要性加权均值最高。Objective To establish an evaluation system for the field assessment of the Kato-Katz technique in detecting soiltransmitted nematodes,so as to provide insights into the field application of the Kato-Katz technique.Methods The initial evaluation indicators were determined through literature search,brainstorming and expert consultation.The evaluation indicators were improved and the weight of each indicator was decided through three rounds of expert consultation by using the Delphi method.In addition,the expert authority coefficient and the coordination coefficient of each indicator were calculated at each round of expert consultations.Results The recovery rates of the questionnaire were 100.00%,100.00%and 89.29%at the first to the third round of the expert consultations,respectively,and the expert authority coefficients were all more than 0.85 at each round.The final evaluation system included 4 first-level indicators and 15 second-level indicators.In the first-level indicators,’’detecting effect’’and’’funds investment’’had the mean weighted value of 4.53 and 4.49,which were relatively higher than that of’’person-time investment’’and"operability’’(both 4.34).Among the second-level indicators under each first-level indicator,the four most significant indicators included’ability of personnel in egg discrimination’’,’’cooperation of village cadres and doctors’’,’’Person-time on testing’’and’’organizational start-up cost’’,with the mean weighted values of 4.74,4.43,4.39 and 4.17,respectively.The coordination coefficients were 0.39 to 0.65,0.28 to 0.58 and 0.45 to 0.65 at the first to the third round of the expert consultations,respectively,and there were significant differences in the coordination coefficients at all three rounds of the consultations(all P<0.05).Conclusion An evaluation system for the field assessment of the Kato-Katz technique in detecting soiltransmitted nematodes is successfully established,among which’’ability of personnel in egg discr
