The Waterlow pressure sore risk calculator is widely used in the UK but has not been found to display high levels of reliability and validity. Few evaluative studies have been carried out in the community. This study aimed to evaluate the Waterlow score when used by district nurses to assess elderly patients. The score was not found to display high levels of reliability, and suffered from a lack of operational definitions within risk categories. In line with other studies, it was found to over-predict pressure sore formation. The findings of this small study suggest that the Waterlow score should not be used as the sole basis for decisions concerning the use of pressure sore prevention resources. High Waterlow scores may be a predictor of ill health in elderly people and this hypothesis requires further examination. The findings also indicate that clarification of the role of risk calculators in general is needed, as many mediating factors appear to affect the ability of a tool to predict pressure sore formation.
沃特洛压疮风险评估量表在英国被广泛使用，但并未显示出高可靠性和有效性。社区中进行的评估研究很少。本研究旨在评估地区护士使用沃特洛评分来评估老年患者的情况。研究发现该评分未显示出高可靠性，且风险类别缺乏操作定义。与其他研究一致，发现它对压疮形成的预测过高。这项小型研究的结果表明，沃特洛评分不应作为决定使用压疮预防资源的唯一依据。高沃特洛评分可能是老年人健康状况不佳的一个预测指标，这一假设需要进一步研究。研究结果还表明，总体上需要明确风险评估量表的作用，因为许多中介因素似乎会影响工具预测压疮形成的能力。
