To assess the specific contribution to overall scale performance of each of the five items that constitute the Norton pressure ulcer prediction scale.
A comparison of statistical models based on cross-sectional surveys of hospitalized patients.
An urban teaching hospital in Geneva, Switzerland.
2373 hospitalized patients who were free of pressure ulcers on admission.
Norton scale items measuring activity, mobility, physical condition, mental condition, and incontinence on a 4-point scale were examined as predictors of stage 1 or greater pressure ulcers.
A total of 245 new pressure ulcers occurred between admission and patient observation. After adjustment for other independent predictors in proportional hazards models, only the activity and mobility items remained associated significantly with the risk of pressure ulcer. A simplified 2-item scale was more strongly associated with pressure ulcer risk than was the classic 5-item Norton scale.
Our study suggests that the activity and mobility items of the Norton scale are sufficient to express the risk of pressure ulcers in hospitalized patients. Confirmation of this finding in prospective studies is warranted.
评估构成诺顿压疮预测量表的五个项目中每个项目对整体量表性能的具体贡献。
基于对住院患者横断面调查的统计模型比较。
瑞士日内瓦的一家城市教学医院。
2373名入院时无压疮的住院患者。
以4分制测量活动、移动性、身体状况、精神状况和失禁情况的诺顿量表项目被作为1期或更严重压疮的预测指标进行研究。
在入院至患者观察期间共发生245例新发压疮。在比例风险模型中对其他独立预测因素进行调整后，只有活动和移动性项目仍与压疮风险显著相关。一个简化的2项量表比经典的5项诺顿量表与压疮风险的相关性更强。
我们的研究表明，诺顿量表的活动和移动性项目足以表达住院患者发生压疮的风险。有必要在前瞻性研究中证实这一发现。
