目的通过科学的研究方法,确立下肢深静脉血栓形成危险因素一、二级指标的权重.方法采用Delphi法对21名专家进行2轮问卷调查,根据专家意见,利用层次分析法(AHP)确定一级指标权重,利用专家重要性评分法确立二级指标权重.结果 3项一级指标血管内皮损伤、血液高凝状态、血流缓慢的归一化权重系数分别为0.3325、0.5278、0.1396,CR=0.0462,21项二级指标中组合权重赋值最高指标为血管外伤,尤其静脉损伤(0.0770),Kendall W=0.422,x2=346.239.结论通过定性与定量的科研方法得出的危险因素指标科学、可靠,为下肢深静脉血栓形成的预防提供了一定的参考依据.

Objective To establish the weights of risk factors indicators for lower limbs deep vein thrombosis through the scientific research methods.Methods 21 experts were consulted for two rounds of questionnaires survey with Delphi method,according to the experts'opinion,analytic hierarchy process (AHP) was used to calculate the weights of indicators in grade one and the experts'evaluation was used to calculate the weights of indicators in grade two.Results The weight coefficients of grade one including vascular endothelial injury,blood high condensation state and slow blood stream were 0.3325,0.5278 and 0.1396 respectively.The items with maximal weights of the 21 indicators in grade two was vascular trauma,in particular vein injury(0.0770).The Kendall's W of the indicators in grade two was 0.422.Conclusions Through qualitative and quantitative research methods,the risk factors indicators which provide the reference for the prevention of lower limbs deep vein thrombosis are scientific and reliable.
