Previously healthy, critically injured survivors of serious trauma are at risk for developing pressure ulcers. A prospective, descriptive, clinical research study was designed to identify the factors associated with the incidence, number, stage, and location of pressure ulcers and to assess the predictive validity of the Braden Scale for Predicting Pressure Sore Risk in this population. A sample of 36 patients was assessed biweekly throughout hospitalization and showed a pressure ulcer incidence of 30.6%. The small sample size in this study precludes generalization of results. However, several findings have potential implications for clinical practice if they can be replicated in larger studies. Total Braden Scale scores were lower for all assessment points in all subjects who developed pressure ulcers. Subscale scores varied in predictive ability from 100% to 0%. Logistic regression using the first two assessment points produced a model that combined mobility and moisture subscale scores. This model correctly predicted 77.78% of those subjects who developed pressure ulcers.
先前健康的严重创伤危重伤者有发生压疮的风险。一项前瞻性、描述性临床研究旨在确定与压疮发生率、数量、分期和部位相关的因素，并评估Braden压疮风险预测量表在该人群中的预测效度。在整个住院期间，每两周对36例患者进行一次评估，结果显示压疮发生率为30.6%。本研究样本量较小，无法将结果推广。然而，如果能在更大规模的研究中得到重复，一些研究结果可能对临床实践具有潜在意义。所有发生压疮的受试者在所有评估点的Braden量表总分均较低。各子量表的预测能力从100%到0%不等。使用前两个评估点进行逻辑回归分析得出一个模型，该模型综合了活动能力和潮湿程度子量表得分。该模型正确预测了77.78%发生压疮的受试者。
