BACKGROUND/OBJECTIVES: Pressure injuries are a significant concern among older adults, particularly in community-based long-term care settings where prolonged immobility is prevalent. This study aimed to identify factors influencing sacral interface pressure in community-dwelling older adults, with an emphasis on support surface usage and clinical risk indicators.
A total of 210 participants aged 65 years and older, all receiving long-term care services in South Korea, were enrolled in this study. Sacral interface pressure was measured in the supine position using a portable pressure mapping device (Palm Q7). General characteristics, Braden Scale scores, Huhn Scale scores, and mattress usage were assessed. Data were analyzed using descriptive statistics, -tests, chi-square tests, and logistic regression.
Mattress non-use was identified as the strongest predictor of elevated sacral interface pressure (OR = 6.71, < 0.001), followed by Braden Scale scores indicating moderate risk (OR = 4.8, = 0.006). Huhn Scale scores were not significantly associated with interface pressure. These results suggest that support surface quality and skin condition have a stronger impact on interface pressure than mobility-related risk factors.
The findings highlight the importance of providing high-quality pressure-relieving mattresses and implementing standardized nursing assessments to reduce the risk of pressure injuries. Integrating smart technologies and expanding access to advanced support surfaces may aid in developing tailored preventive strategies for vulnerable older adults.
背景/目的：压疮是老年人中的一个重大问题，尤其是在社区长期护理环境中，长期卧床不动的情况很普遍。本研究旨在确定影响社区居住老年人骶部界面压力的因素，重点关注支撑面的使用情况和临床风险指标。
本研究共纳入了210名65岁及以上、在韩国接受长期护理服务的参与者。使用便携式压力映射设备（Palm Q7）在仰卧位测量骶部界面压力。评估了一般特征、Braden量表评分、Huhn量表评分和床垫使用情况。数据采用描述性统计、t检验、卡方检验和逻辑回归进行分析。
未使用床垫被确定为骶部界面压力升高的最强预测因素（OR = 6.71，P < 0.001），其次是表明中度风险的Braden量表评分（OR = 4.8，P = 0.006）。Huhn量表评分与界面压力无显著关联。这些结果表明，支撑面质量和皮肤状况对界面压力的影响比与活动相关的风险因素更大。
研究结果强调了提供高质量减压床垫和实施标准化护理评估以降低压疮风险的重要性。整合智能技术并扩大获得先进支撑面的机会可能有助于为脆弱的老年人制定量身定制的预防策略。
