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.
ABSTRACT
Objective To build emergency specialist nurse training evaluation index system model.Methods By Delphi method,21 emergency care specialists participated in the consultation,using the Analytic Hierarchy Process (AHP)to build a hierarchical model,establishing judgment matrix,through statistical calculations to determine the indicators and weight coefficients of the index system of emergency specialist nurse training.Results Four first-level indicators,11 second-level indicators,31 third-level indicators emergency specialist nurse training evaluation system model were established.Conclusions Establishment of emergency nurse specialist training evaluation index system provides an effective method and reference to improve the overall capacity of the emergency specialist nursing team to ensure the quality of training of emergency nurse specialists.
