DESCRIPTION (provided by applicant): Problems associated with the difficulty in detecting Stage I pressures ulcers in elderly and disabled patients with darker skin tones are becoming more important due to the increasing disparity in the incidence of advanced pressure ulcers in these populations compared to populations with lighter skin tones, the complications that can arise from the delay in detecting pressure ulcers, the difficulty and cost associated with treatment of advanced pressure ulcers, and the projected growth in minority populations with darker skin tones. In this study we will: 1- Validate Imaging-Based Stage I Pressure Ulcer Detection methods against the judgment of a sample of observers 2- Develop and evaluate a low-cost, easy to use imaging-based Stage I Pressure Ulcer Detector capable of detecting such a condition in subjects with dark skin pigmentation. The purpose of this proposal is to validate, develop, and evaluate a low cost, non-contact system intended for use by professional caregivers in different settings including long-term care settings. The emergent system would be easy to use and capable of providing immediate feedback in the form of a real-time display, i.e. observer-based. Our previous research and preliminary results showed great promise for broadband imaging in the visible (e.g., red/green) and narrow-band visible imaging when coupled with image enhancement, even in the darkest skin tones. If successful, the proposed study can result in a tool that can reduce health disparity and improve health outcomes for affected minority populations, while likely reducing the cost of care.

The impacts of this technology include the potential of reducing the cost of care. In addition, the technology is a tool that has the potential to assess and characterize different types of erythema in diverse clinical populations, including the elderly and the disabled, and to evaluate the efficacy of interventions.

描述（申请人提供）：与在具有较深肤色的老年和残疾患者中检测I期压疮的困难相关的问题变得更加重要，这是由于与具有较浅肤色的人群相比，这些人群中晚期压疮的发生率的差异越来越大，可能由检测压疮的延迟引起的并发症，与晚期压疮治疗相关的困难和成本，以及肤色较深的少数群体的预计增长。在本研究中，我们将：1-根据观察者样本的判断，开发并评估一种低成本、易于使用的基于成像的I期压疮检测器，该检测器能够检测具有深色皮肤色素沉着的受试者的这种状况。本提案旨在确认、开发和评价一种低成本、非接触式系统，供专业护理人员在不同环境（包括长期护理环境）中使用。该紧急系统将易于使用，并能够以实时显示的形式提供即时反馈，即基于任何人。我们以前的研究和初步结果表明，在可见光（例如，红/绿色）和窄带可见光成像，即使在最暗的肤色中也是如此。如果成功，拟议的研究可以产生一种工具，可以减少健康差距，改善受影响少数群体的健康结果，同时可能降低护理成本。本提案的目的是确认、开发和评价一种低成本、非接触、基于成像的I期压疮检测系统，该系统预期由专业护理人员在不同环境（包括长期护理环境）中使用。该紧急系统将易于使用，并能够以实时显示的形式提供即时反馈，即基于任何人。我们以前的研究和初步结果表明，在可见光（例如，红/绿色）和窄带可见光成像，即使在最暗的肤色中也是如此。如果成功，拟议的研究可以产生一种工具，可以减少健康差距，改善受影响少数群体的健康结果。这项技术的影响包括降低护理成本的潜力。此外，该技术是一种工具，有可能评估和表征不同临床人群（包括老年人和残疾人）中不同类型的红斑，并评估干预措施的有效性。
