From previous work serum albumin is predictive of pressure ulcers over and above the Waterlow score. However the sub-scores of the Waterlow score were not available, and the accuracy of calculation of the total score was poor. This study has used sub-scores and is an order of magnitude larger.
To compare serum albumin with Waterlow score as a predictive measure for pressure ulcers.
Retrospective analysis of hospital information support system.
A district general hospital in Staffordshire.
Adult non-elective in-patients.
Logistic regression and receiver operating characteristic.
The sub-scores of the Waterlow score were explored. While they constitute a multi-dimensional dataset, many were not found relevant to pressure ulcer risk in this population (non-elective in-patients). Some sub-scores were not recorded correctly, and body mass index (BMI) was particularly badly reported. Age was found to be as predictive of pressure ulcer as the more complex Waterlow score. Serum albumin was at least as good as the Waterlow score in risk assessment of pressure ulcers. Matching patients with pressure ulcers to patients with none, who had identical Waterlow sub-scores, confirmed serum albumin as a robust predictive value in pressure ulcers.
Risk assessing patients based on their age is as good as the more complex Waterlow score. Additional risk information can be gained from knowing the serum albumin value.
既往研究表明，血清白蛋白水平可预测压疮的发生，且优于 Waterlow 评分。然而，Waterlow 评分的子项评分并不完整，且总分的计算准确性较差。本研究使用了子项评分，且样本量更大。
比较血清白蛋白和 Waterlow 评分作为压疮预测指标的准确性。
医院信息支持系统的回顾性分析。
斯塔福德郡的一家地区综合医院。
成年非择期住院患者。
逻辑回归和受试者工作特征曲线。
对 Waterlow 评分的子项评分进行了探索。虽然它们构成了一个多维数据集，但在本研究人群（非择期住院患者）中，许多子项评分与压疮风险无关。一些子项评分记录不正确，且体重指数（BMI）的报告尤其不准确。年龄与 Waterlow 评分一样，对压疮的预测能力较强。血清白蛋白在压疮风险评估中的准确性至少与 Waterlow 评分相当。将患有压疮的患者与具有相同 Waterlow 子项评分但无压疮的患者进行匹配，进一步证实了血清白蛋白是压疮的一个可靠预测指标。
基于年龄评估患者的风险与更为复杂的 Waterlow 评分一样准确。了解血清白蛋白值可提供额外的风险信息。
