摘要:
目的 进行集中空调卫生监督量化评分指标筛选和权重赋值,构建集中空调卫生监督量化评分指标体系。 方法 采用德尔菲专家咨询法,对上海市集中空调领域15位专家进行两轮咨询,确定集中空调卫生监督量化评分一、二级指标、关键项及其权重。 结果 15位专家的两轮咨询表的积极系数均为100%。专家权威程度在0.71~0.97之间,均值为0.82。组织管理、检测情况管理、新风系统及机房管理、空气处理设施设备管理、风管管理、风口管理、冷却塔管理等7项一级指标,卫生管理组织及人员等33项二级指标的算术平均值均>4。7项一级指标变异系数均<0.25;33项二级指标中变异系数<0.25的指标占81.8%。第二轮咨询总体协调系数为0.330,经统计学检验,P<0.01。 结论 参与问卷调查的专家意见一致性好,德尔菲法构建的集中空调卫生监督量化评分指标体系有效。 Abstract:Objective To construct a quantitative evaluation index system for health supervision of central air conditioning through indicator selection and weight assignment. Methods A two-round Delphi consultation was held among 15 experts on central air conditioning in Shanghai to determine the first and the second order indicators, critical items, and index weights. Results The return rate of Delphi consultation tables was 100% in both rounds. The authority coefficient ranged from 0.71 to 0.97, and the mean value was 0.82. The mean values were greater than 4 in seven first order indicators (i.e. organizational management, test management, fresh air system and computer room management, air treatment equipment management, wind pipe management, air vent management, cooling tower management) and thirty-three second order indicators (such as organizations and personnel). The variability coefficients of the seven first order indicators were all less than 0.25, and 81.8% of the thirty-three second order indicators had variability coefficients less than 0.25. The total coordinate coefficient of the second round of consultation was 0.330 (P<0.01). Conclusion The findings indicate consensus achieved among the invited experts. The Delphi method is effective in constructing the quantitative evaluation index system for health supervision of central air conditioning.
