title: Intensive care unit management of fever following traumatic brain injury.
abstract: Fever, in the presence of traumatic brain injury (TBI), is associated with worsened neurologic outcomes. Studies prior to the publication of management guidelines revealed an undertreatment of fever in patients with neurologic insults. Presently the adult TBI guidelines state that maintenance of normothermia should be a standard of care therefore improvement in management of fever in these patients would be expected. The specific aims of the study were to: (1) determine the incidence of fever (T>or=38.5 degrees C) in a population of critically ill patients with TBI; (2) describe what interventions were recorded by intensive care unit (ICU) nurses in managing fever; (3) ascertain the rate of adherence with published normothermia guidelines. Medical record review of available hospital records was conducted on patients admitted to a level I trauma center following severe TBI (N=108) from the parent study. Temperature data was abstracted and contemporaneous nursing documentation was examined for evidence of intervention for fever and adherence with published standards. Data analyses were performed that included descriptive statistics. Seventy-nine percent of TBI patients (85/108) had at least one recorded fever event while in the ICU. However in only 31% of events did the patient receive any documented intervention by nursing staff for the elevated temperature. The most frequently documented intervention was pharmacologic (358/1166 elevations). Other nursing actions (e.g. use of fan) accounted for a minority (<1%) of nursing interventions documented. Patients were more likely to have a high temperature that exceeded 40 degrees C (13%) than a temperature that was normothermic (5%). There continues to be an under treatment of fever in patients with TBI by critical care nurses despite our knowledge of its negative effects on outcomes. There remains a gap in translation between patient outcomes research and bedside practice that needs to be overcome, thus research efforts need to now focus on understanding nurses' decision-making processes and the best methods of fever reduction in patients with TBI.
