Abstract: 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.
