项目摘要
DESCRIPTION (provided by applicant): Traumatic brain injury (TBI) is a leading cause of death and disability, contributing to one third of all injury- related deaths in the U.S. There has
been an increased awareness of TBI as the "signature wound" of current military conflict. Despite best-care practices based on published guidelines, many patients have poor outcomes due to secondary injuries. Secondary injuries occur after the primary trauma. Failure to treat secondary injury leads to lengthened intensive care unit and hospital stays and increased mortality. Identification of strategies that can prevent or minimize secondary injuries results in improved health of individuals, families, communities, and populations. Temperature management is one method to reduce secondary injury. However, the optimal goal for body temperature following TBI has not been identified. The purpose of this secondary data analysis of 456 patients is to examine the association between body temperature and neurologic outcome as measured by Extended Glasgow Outcome Scale (GOS-E) in patients ages 16 years and older after blunt moderate or severe TBI. We propose that features of body temperature over 96 hours after injury predict 6-month GOS-E adjusting for confounders. The aims of this training proposal are to: 1) Characterize the severity and duration of time the patien experiences abnormal body temperature during the first 96 hours after moderate or severe TBI; 2) Determine if aberrant temperature exposure during this period predicts neurologic outcome adjusting for confounders; 3) Determine if rate of aberrant temperature correction during this period predicts neurologic outcome adjusting for confounders; and 4) Gather an interdisciplinary panel to validate findings and identify potential implications for future research nursing practice Multiple ordinal regression analysis will be used to estimate the relative contribution of IMPACT variables (age, GCS motor score, pupillary reaction, hypoxia, hypotension, initial head CT classification, traumatic subarachnoid hemorrhage or epidural mass on CT, serum glucose, and serum hemoglobin) in predicting GOS- E. Proportion of variation in GOS-E explained by IMPACT variables will be estimated. Temperature volume will be added to the model and change in variance of GOS-E explained by the addition of temperature volume will be estimated. Then, the rate of change in temperature across the 96-hour period will be added and change in variance of GOS-E explained by the addition of the rate of change in temperature will be estimated. Meeting these study aims, we may develop a more useful predictive model, which is readily translatable to nursing practice. We seek to build the scientific foundation for nursing
practice. As nurses monitor, document and treat patient body temperature, this research has the potential to influence rewarming rates in trauma resuscitation with TBI, temperature management goals after TBI, and timing of interventions to prevent/minimize fever after TBI. Finally, temperature management following TBI may improve outcomes at a relatively low cost.
PUBLIC HEALTH RELEVANCE: This proposal has high impact given the prevalence and societal effect of traumatic brain injury. Traumatic brain injury contributes to one third of all injury-related deaths in the U.S. Despite best-care practices based on published guidelines, many patients have poor outcomes due to secondary injuries. Nurses are in an excellent position to intervene to manage body temperature. New discoveries from this research may help to prevent and/or minimize disability and death by reducing secondary injury resulting from abnormal body temperature.
描述(由申请人提供):创伤性脑损伤 (TBI) 是导致死亡和残疾的主要原因,占美国所有伤害相关死亡的三分之一。
人们越来越认识到创伤性脑损伤是当前军事冲突的“标志性伤口”。尽管根据已发布的指南采取了最佳护理实践,但许多患者由于继发性损伤而预后不佳。继发性损伤发生在原发性损伤之后。未能治疗继发性损伤会导致重症监护室和住院时间延长以及死亡率增加。确定可以预防或尽量减少继发伤害的策略可以改善个人、家庭、社区和人群的健康。温度管理是减少二次伤害的方法之一。然而,TBI 后的最佳体温目标尚未确定。对 456 名患者进行二次数据分析的目的是检查 16 岁及以上钝性中度或重度 TBI 后患者的体温与神经系统结果之间的关联,神经系统结果是通过扩展格拉斯哥结果量表 (GOS-E) 测量的。我们建议,受伤后 96 小时内的体温特征可以预测 6 个月的 GOS-E 对混杂因素的调整。本培训计划的目的是: 1) 描述患者在中度或重度 TBI 后的前 96 小时内经历体温异常的严重程度和持续时间; 2) 确定在此期间的异常温度暴露是否可以预测针对混杂因素进行调整的神经系统结果; 3) 确定在此期间的异常温度校正率是否可以预测针对混杂因素调整的神经系统结果; 4) 组建一个跨学科小组来验证研究结果并确定对未来研究护理实践的潜在影响 多重序数回归分析将用于估计 IMPACT 变量(年龄、GCS 运动评分、瞳孔反应、缺氧、低血压、初始头部 CT 分类、CT 上的创伤性蛛网膜下腔出血或硬膜外肿块、血清葡萄糖和血清血红蛋白)在预测中的相对贡献 GOS-E。将估计 IMPACT 变量解释的 GOS-E 变化比例。温度体积将被添加到模型中,并且将估计由温度体积的添加所解释的 GOS-E 方差的变化。然后,将添加 96 小时内的温度变化率,并估计由添加温度变化率解释的 GOS-E 方差变化。满足这些研究目标,我们可以开发一种更有用的预测模型,该模型很容易转化为护理实践。我们致力于建立护理的科学基础
实践。由于护士监测、记录和治疗患者体温,这项研究有可能影响 TBI 创伤复苏的复温率、TBI 后的体温管理目标,以及预防/减少 TBI 后发烧的干预措施的时机。最后,TBI 后的温度管理可以以相对较低的成本改善结果。
公共卫生相关性:鉴于创伤性脑损伤的普遍性和社会影响,该提案具有很大影响。在美国,创伤性脑损伤占所有伤害相关死亡的三分之一。尽管根据已发布的指南采取了最佳护理实践,但许多患者由于继发性伤害而预后不佳。护士可以很好地进行干预以控制体温。这项研究的新发现可能有助于通过减少体温异常造成的继发性伤害来预防和/或最大限度地减少残疾和死亡。
