Objective To evaluate the risk of pressure ulcer in patients with neurosurgical diseases more exactely, and to reduce the occurrence rate of pressure ulcer. Methods The risk factors of 500 patients with wneurosurgical diseases were evaluated using two scales(the self-designed pressure ulcer risk measuring scale and the Braden scale),and the reliability and validity were compared. Results The Cronbaeh'S α for self-made pressure ulcer measuring scale was 0.941,that for Braden scale was 0.743.The factor analysis showed both two measuring scale had good structural validity. When diagnose critical value for self-made measuring scale arrived to 16,the sensitivity was 89％ and the specificity was 78％.When diagnose critical value for Braden scale arrived to 18,the sensitivity was 78％and the specificity was 58％. Conclusions The two measuring scales bear good reliability, structural validity and predictive validity, but self-made pressure ulcer measuring scale is better than Braden scale in patients with neurosurgical diseases. Self-designed pressure ulcer measuring scale could be a suitable measuring tool in the prediction of pressure ulcer for patients with neurosurgical disease.%目的 更准确地评估神经外科患者发生压疮的危险性,降低压疮发生率.方法 采用两个评估量表(即自制神经外科压疮危险因素评估量表和Braden量表)评估500例神经外科患者的压疮危险因素,并进行信度和效度的比较.结果 自制神经外科压疮危险因素评估量表的Cronbach's α为0.941,Braden量表的Cronbach's α为0.743.因子分析结果显示,两个量表的结构效度与原设想的基本一致.预测效度显示,当自制神经外科压疮危险因素评估量表的诊断界值取16分时,灵敏度和特异度分别为89%和78%;当Braden量表取18分时,灵敏度和特异度分别为78%和58%.结论 两种量表均具有较好的内部一致性信度、结构效度和预测效度,但自制神经外科压疮危险因素评估量表优于Braden量表,是适合神经外科患者人群的压疮危险评估工具.
