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（由申请人提供）：与检测阶段I的难度相关的问题，由于这些人群中高级压力溃疡的发生率的增加，老年人和残疾人肤色较深的肤色溃疡变得越来越重要。较轻的肤色，可能是由于检测压力溃疡的延迟而引起的并发症，与晚期压力溃疡治疗相关的困难和成本以及预计的少数族裔人群的增长较深。在这项研究中，我们将：1-基于成像的I期压力溃疡检测方法，反对观察者样本的判断2-开发和评估低成本，易于使用的基于成像的I期压力溃疡探测器能够检测在具有深色皮肤色素沉着的受试者中的这种情况。该建议的目的是验证，开发和评估低成本的非接触系统，旨在在包括长期护理环境在内的不同环境中使用专业护理人员。紧急系统将易于使用，并且能够以实时显示的形式（即基于观察者）提供即时反馈。我们以前的研究和初步结果表明，当与图像增强（即使是在最黑暗的肤色中）结合时，可见光（例如红色/绿色）和窄带可见成像的宽带成像很大。如果成功的话，拟议的研究可能会导致一种可以减少健康差异并改善受影响少数群体的健康结果的工具，同时可能会降低护理成本。该提案的目的是验证，开发和评估低成本，非接触，基于Imaging阶段的I阶段压力溃疡检测系统，旨在在包括长期护理环境在内的不同环境中专业护理人员使用。紧急系统将易于使用，并且能够以实时显示的形式（即基于观察者）提供即时反馈。我们以前的研究和初步结果表明，当可见光（例如红色/绿色）和窄带可见成像与图像增强（即使是在最黑暗的肤色中）时，宽带成像的巨大希望。如果成功，拟议的研究可能会导致一种可以减少健康差异并改善受影响少数群体的健康结果的工具。该技术的影响包括降低护理成本的潜力。此外，该技术是一种具有评估和表征不同临床人群（包括老年人和残疾人）的不同类型红斑的工具，并评估干预措施的功效。
