本研究探讨了老年人皮肤生理指标与压疮之间的关系。研究对象是 55 名卧床不起的日本老年患者，中位年龄为 85 岁。使用非侵入性设备测量以下参数：皮肤表面温度、角质层含水量、真皮含水量、作为皮肤屏障功能指标的经表皮失水量、皮肤红斑和皮肤弹性。骶骨和两个脚后跟区域被观察为容易发生压疮的部位。在测量皮肤生理指标后的一个月内，我们根据医疗记录确认了国家压疮咨询小组分类II期或更严重的压疮。在 55 名患者中，有 4 名患者（7.3%）在 16 天内总共出现了 5 处压疮。仅皮肤红斑评分显着高于无压疮的患者 (p < 0.001)。我们进行了二元逻辑回归分析，并证实压疮发展与红斑水平之间存在显着关系（优势比=1.026；95%置信区间：1.011-1.042）。在发生压疮之前，皮肤红斑会增加。综上所述，我们的结果表明，高皮肤红斑评分可以作为压疮的预测指标。
This study examined the relationship between skin physiological indices and pressure ulcers in elderly people. The subjects were 55 bedridden elderly Japanese patients with a median age of 85 years. The following parameters were measured using non-invasive devices: skin surface temperature, moisture content in the stratum corneum, moisture content in the dermis, transepidermal water loss as an index of skin barrier function, skin erythema and skin elasticity. The sacral and 2 heel areas were observed as sites predisposed to pressure ulcers. Within one month after measuring the skin physiological indices, we confirmed pressure ulcers of National Pressure Ulcer Advisory Panel classification Stage II or worse based on medical records. Among the 55 patients, 4 (7.3%) prospectively developed a total of 5 pressure ulcers within 16 days. Only the skin erythema score was significantly higher with than without pressure ulcers (p < 0.001). We performed a binary logistic regression analysis and confirmed a significant relationship between pressure-ulcer development and the level of erythema (odds ratio=1.026; 95% confidence interval: 1.011-1.042). Skin erythema increased before the development of pressure ulcers. Taken together, our results show that the high skin erythema score can be a predictive indicator of pressure ulcers.
