National pressure ulcer prevalence surveys have found a higher proportion of severe pressure ulcers among dark skinned hospital patients than among Caucasians. The National Pressure Ulcer Advisory Panel has identified early detection of erythema in people with darkly pigmented skin to be a major clinical problem. We propose developing tools to assist nursing personnel in identifying erythema in darkly pigmented skin and better categorize it in people with all types of skin pigmentation. During phase l research we will develop and test a simple and inexpensive device, similar in shape to a fat thimble, that can be worn on a gloved or ungloved finger to indicate the degree of erythema and the "blanchability" of skin beneath it, independent of skin pigmentation. In phase 2, we will refine the human interface and manufacturability of this basic system and evaluate its utility in a variety of health care settings. We will also develop and test a more sophisticated hand held instrument to quantitatively differentiate between several degrees of blanchable and non-blanchable erythema that cannot currently be distinguished. We will conduct trials to determine if there is clinical utility for these additional skin assessment functions. This technology is especially applicable to the needs of our aging minority populations. PROPOSED COMMERCIAL APPLICATIONS: This instrument will confirm or deny a diagnosis of stage l pressure ulcer for people with darkly pigmented skin. Currently, failure to recognize such stage l ulcers leads to the high incidence of full skin thickness pressure ulcers in minority patients with dark skin. Our easy to use, thimble shaped erythema detector will save hospitals and nursing homes money by reducing the currently high incidence of advanced pressure ulcers in Hispanics and African Americans.

全国压疮患病率调查发现，深色皮肤的医院患者中严重压疮的比例高于白种人。国家压疮咨询小组已确定深色皮肤人群红斑的早期发现是一个主要的临床问题。我们建议开发工具来帮助护理人员识别深色皮肤中的红斑，并更好地对所有类型皮肤色素沉着的人进行分类。在第一阶段研究中，我们将开发和测试一种简单且廉价的设备，其形状类似于胖顶针，可以戴在戴手套或不戴手套的手指上，以指示红斑程度及其下方皮肤的“变白程度”，与皮肤色素沉着无关。在第二阶段，我们将完善这一基本系统的人机界面和可制造性，并评估其在各种医疗保健环境中的实用性。我们还将开发和测试一种更复杂的手持式仪器，以定量区分目前无法区分的几种程度的漂白和非漂白红斑。我们将进行试验以确定这些额外的皮肤评估功能是否具有临床实用性。这项技术特别适用于我们老龄化少数民族人口的需求。拟议的商业应用：该仪器将确认或否认深色皮肤人群的 I 期压疮的诊断。目前，由于未能识别这种I期溃疡，导致少数深色皮肤患者全皮压疮的发生率很高。我们易于使用的顶针形红斑检测仪将通过减少目前西班牙裔和非裔美国人中晚期压疮的高发病率来节省医院和疗养院的资金。
