项目摘要

DESCRIPTION (provided by applicant): Pressure ulcers continue to be a serious secondary complication for people with impaired mobility and sensation. They affect older people and persons with many disabilities including spinal cord injury, multiple sclerosis, stroke, amputation and dementia. The cost in health care dollars to heal pressure ulcers, estimated to cost billions of dollars, is easily surpassed by the cost of ulcers measured in human terms, which can include loss of employment, independence and death. Pressure ulcers have been identified as a public health concern by the federal government via inclusion in Healthy People 2010 and by the National Quality Forum (NQF). Pressure ulcers develop in several ways, but their progression can be roughly grouped into two classes. Some ulcers begin superficially after ischemic damage to the epidermis and dermis. These ulcers begin as Stage I ulcers that are characterized by persistent erythema. Because erythema is hard to visualize in persons with dark skin, Blacks and dark skin Hispanics are at increased risk of ulcer development. The other type of pressure ulcer starts deep in tissue, typically at the level of an underlying bony prominence. This deep tissue injury goes undetected until it progresses toward the surface and presents as a bruising or discoloration. Both these etiologies of ulcers would greatly benefit from early detection. However, technology is currently unavailable to nurses and nurse assistants, who are typically charged with skin inspections. The overall goal of the project is the development and testing of imaging technology to be used in a clinically-affordable and portable device to identify incipient pressure ulcers and deep tissue injury. This erythema and deep tissue injury (E&DTI) detector will be used by healthcare practitioners who work with people who are at risk of developing pressure ulcers. The intended impact of the device is to enhance clinician visual assessment of skin to prevent the occurrence of pressure ulcers. A significant focus is on enhanced detection in people with darkly pigmented since, in whom visual inspection is problematic.

描述（由申请人提供）：压疮仍然是一个严重的继发性并发症的人与受损的流动性和感觉。它们影响老年人和患有多种残疾的人，包括脊髓损伤、多发性硬化症、中风、截肢和痴呆症。治疗压力性溃疡的医疗费用估计为数十亿美元，很容易被以人类为单位衡量的溃疡成本所超过，其中包括失业，独立和死亡。联邦政府通过纳入2010年健康人群和国家质量论坛（NQF），已将压疮确定为公共卫生问题。压力性溃疡的发展有几种方式，但它们的进展可以大致分为两类。有些溃疡开始于表皮和真皮缺血性损伤后的浅表。这些溃疡开始为以持续性红斑为特征的I期溃疡。因为红斑在深色皮肤的人中很难看到，黑人和深色皮肤的西班牙裔人患溃疡的风险增加。另一种类型的压力性溃疡开始于组织深处，通常在潜在的骨突起的水平。这种深层组织损伤在向表面发展并表现为瘀伤或变色之前不会被发现。溃疡的这两种病因都将大大受益于早期发现。然而，目前护士和护士助理无法获得这项技术，他们通常负责皮肤检查。该项目的总体目标是开发和测试成像技术，用于临床负担得起的便携式设备，以识别早期压疮和深部组织损伤。这种红斑和深层组织损伤（E&DTI）检测器将由与有压疮风险的人一起工作的医疗保健从业人员使用。该器械的预期影响是增强临床医生对皮肤的视觉评估，以防止发生压疮。一个重要的重点是增强检测的人与深色色素，因为在视觉检查是有问题的。
