OBJECTIVE MEASUREMENT OF PRESSURE SORE RISK

随着医疗保健技术的复杂性和精确性的提高，重病和受伤患者的存活率也有所提高。压疮的搜身检查是这一人群的重要护理问题。全国PU处理的总费用估计超过13.35亿美元。准确的护理评估、护理诊断和及时的护理干预是认识和缓解压力的必要条件。在压力可以缓解的情况下，脓肿通常可以预防。目前的护理风险评估工具由主观风险量表组成，尚未被证明在人群中是可靠的。我的长期研究目标是开发一种对PU风险的客观测量方法，这种方法在人群中是可靠和有效的。本实验研究将测试两种有前景的无创测量方法——经皮血氧仪和皮肤表面温度——的精确性和准确性，以确定两组住院成年人的PU风险：有明显或轻微运动的和不动的。压力引起的短暂性循环障碍将通过将受试者置于床上仰卧位2小时来完成。收集到的数据将输入计算机，并使用SPSS for Windows （version 9.0）进行分析。

As health care technology increases in complexity and precision, survival rates among seriously ill and injured patients have increased. Frisk for pressure ulcers (PUs) is a significant nursing problem in this population. The total national cost of PU treatment has been estimated to exceed 1.335 billion dollars. Accurate nursing assessment, nursing diagnosis, and prompt nursing intervention are required for recognition and relief of pressure. In situations where pressure can be relieved, PUs can often be prevented. Current nursing risk assessment tools consist of subjective risk scales that have not been shown to be reliable across populations. My long-term research goal is to develop an objective measure of PU risk that is reliable and valid across populations. This experimental study will test the precision and accuracy of two promising noninvasive measures, transcutaneous oximetry and skin surface temperature, to identify PU risk in two contrasted groups of hospitalized adults: those who make gross or subtle movements and those who do not move. Pressure-induced, transitory circulatory impairment will be accomplished by placing the subject in the supine position in bed for 2 hours. Collected data will be entered into a computer and analyzed using SPSS for Windows (version 9.0)
