脑卒中患者跌倒风险评估体系构建

Construction of Fall Risk Assessment System for Stroke Patients

目的构建脑卒中患者跌倒风险评估体系,为开发脑卒中患者跌倒风险预测模型提供依据。方法通过文献分析法和专家小组讨论法拟定指标条目池,经过两轮专家函询筛选指标,依据重要性评分算术平均数确定指标权重。结果最终构建包括6个一级指标和31个二级指标的脑卒中患者跌倒风险评估体系。两轮函询专家积极系数分别为86.67%和100%,专家平均权威系数为0.91,第二轮函询一级、二级指标Kendall’s W系数分别为0.203、0.344。结论评估体系具有一定科学性和可靠性,可为脑卒中患者跌倒风险评估提供科学、有效的工具。

Objective To construct an system of fall risk assessment for stroke patients,and to provide basis for the development of fall risk prediction model for stroke patients.Methods The index item pool was drawn up through literature analysis and expert group discussion.After two rounds of expert correspondence consultation,indicators were screened,and index weights were determined according to the arithmetic mean of importance scores.Results Finally,a fall risk assessment system for stroke patients was constructed,including 6 primary indexes and 31 secondary indexes.The positive coefficient of experts in the two rounds of correspondence consultation was 86.67%and 100%,and the average authority coefficient of experts was 0.91.Kendall's W coefficient of primary and secondary indicators in the second round of correspondence consultation was 0.203 and 0.344,respectively.Conclusion The evaluation system is scientific and reliable,and can provide a scientific and effective tool for the fall risk assessment of stroke patients.
