Practice management guidelines for geriatric trauma: the EAST Practice Management Guidelines Work Group.

Abstract

Advanced age is a well-recognized risk factor for adverse outcomes after trauma. A substantial body of literature, much of it cited within this article, demonstrates increased morbidity and mortality in geriatric trauma patients compared with their younger counterparts. Whether this outcome difference is because of the decreased physiologic reserve that accompanies aging, a higher incidence of preexisting medical conditions in the geriatric patient, or other factors yet to be identified remains unclear. It is clear, however, that good outcomes can be achieved in this patient population when appropriately aggressive trauma care is directed toward geriatric patients with survivable injuries. Implicit in the above statement is the need to identify, as soon as possible after injury, those patients who will benefit from aggressive resuscitation, timely injury management, and posttrauma rehabilitation. It is equally important, however, to limit these intensive and expensive treatment modalities to patients whose injuries are not only survivable but also compatible with an acceptable quality of life. Our purpose in developing this guideline was to provide the trauma practitioner with some evidence-based recommendations that could be used to guide decision-making in the care of the geriatric trauma patient. We began this process by first developing a series of questions, the answers to which we hoped could be supported by the existing scientific literature. The initial set of questions were as follows: 1. Is age itself a marker of increased morbidity/ mortality? If so, what age should be used? 2. Is age instead a surrogate for increased preexisting conditions (PECs)? If so, which premorbid conditions are particularly predictive of poor outcomes? 3. Should age itself be a criterion for triage from the field directly to a trauma center, regardless of Glasgow Coma Scale (GCS) score, Trauma Score (TS), and so forth? If so, what age should be used? 4. Do trauma centers have better outcomes with geriatric trauma than nontrauma centers? 5. Are there specific injuries, scores (e.g., Injury Severity Score [ISS], TS, GCS score), or PEC/age combinations in geriatric trauma patients that are so unlikely to be survivable that a nonaggressive approach from the outset could be justified? 6. What resuscitation end-points should be used for the geriatric trauma patient? 7. Should all geriatric trauma patients receive invasive hemodynamic monitoring? If so, what specific types of monitoring should be used? If not, which geriatric patients benefit from invasive monitoring? Unfortunately, after examining the available literature, it is clear that evidence-based responses to all of the questions raised above are not possible. As the evidentiary tables demonstrate, there are few, if any, prospective, randomized, controlled trials that definitively address any of the above issues. Second, there is a lack of uniformity as to a specific age criterion for geriatric trauma. As shown in the evidentiary tables, geriatric trauma is variously defined in the literature as age greater than or equal to 55, 60, 65, 70, 75, and even 80 years of age. There is even literature support for increased mortality from trauma beginning at age 45! Furthermore, because age is a continuous variable, and not a dichotomous one, adverse outcomes associated with geriatric trauma are likely to increase in a continuous fashion with age as opposed to a stepwise leap as a given patient reaches a specific age. Third, there is no concise definition of a geriatric trauma patient. In some studies, all patients over a given age are included, whereas in others, patients with penetrating injuries, burns, and minor injuries, such as slip-and-falls, are excluded. Some studies include all patients regardless of hemodynamic instability or injury severity, whereas others impose strict entrance criteria or exclude patients who do not survive for a predetermined period of time after admission. Such lack of uniformity regarding inclusion criteria makes it Submitted for publication October 3, 2001. Accepted for publication September 16, 2002.
