Continued Relevance of Initial Temperature Measurement in Trauma Patients

Reliability of the safety threats and adverse events in trauma (STAT) taxonomy using trauma video review

PURPOSE

The STAT (Safety Threats and Adverse Events in Trauma) taxonomy was developed through expert consensus, and groups 65 identified trauma resuscitation adverse events (AEs) into nine distinct categories. It provides a framework for standardized analysis of trauma resuscitations and creates a foundation for targeted quality improvement and patient safety initiatives. This study aims to evaluate the reliability of the STAT taxonomy in identifying AEs during video-recorded trauma resuscitations.

METHODS

High-definition audiovisual data from 30 trauma resuscitations were reviewed. Videos were assessed and scored by four independent reviewers (two trainees and two staff). The STAT taxonomy was used to identify AEs based on binary responses: yes and no. Inter-rater reliability was calculated using Gwet's AC1. The frequencies of AEs were tallied and reported as counts and percentages.

RESULTS

The most common AEs identified in the videos were failure to measure temperature (86.7%) and inadequate personal protective equipment (86.7%), followed by inability to use closed-loop communication (76.7%). The agreement on all AEs between reviewers was 0.94 (95% CI: 0.93-0.95). The Gwet's AC1 agreement across the 9 AE categories was paramedic handover (0.82), airway and breathing (0.99), circulation (0.95), assessment of injuries (0.91), management of injuries (0.96), procedure-related (0.97), patient monitoring and IV access (0.99), disposition (0.98), team communication and dynamics (0.87).

CONCLUSION

The STAT taxonomy demonstrated excellent inter-rater reliability between reviewers and can be used to identify AEs in video-recorded trauma resuscitations. These results provide a foundation for adapting video review to objectively quantify and assess AEs in the trauma bay.

American Association for the Surgery of Trauma/American College of Surgeons Committee on Trauma: Clinical protocol for damage-control resuscitation for the adult trauma patient

ABSTRACT

Damage-control resuscitation in the care of critically injured trauma patients aims to limit blood loss and prevent and treat coagulopathy by combining early definitive hemorrhage control, hypotensive resuscitation, and early and balanced use of blood products (hemostatic resuscitation) and the use of other hemostatic agents. This clinical protocol has been developed to provide evidence-based recommendations for optimal damage-control resuscitation in the care of trauma patients with hemorrhage.

Prehospital Active and Passive Warming in Trauma Patients

OBJECTIVE

Hypothermia is common among trauma patients and can lead to a serious rise in morbidity and mortality. This study was performed to investigate the effect of active and passive warming measures implemented in the prehospital phase on the body temperature of trauma patients.

METHODS

In a multicenter, multinational prospective observational design, the effect of active and passive warming measures on the incidence of hypothermia was investigated. Adult trauma patients who were transported by helicopter emergency medical services (HEMS) or ground emergency medical services with an HEMS physician directly from the scene of injury were included. Four HEMS/ground emergency medical services programs from Canada, the United States, and the Netherlands participated.

RESULTS

A total of 80 patients (n = 20 per site) were included. Eleven percent had hypothermia on presentation, and the initial evaluation occurred predominantly within 60 minutes after injury. In-line fluid warmers and blankets were the most frequently used active and passive warming measures, respectively. Independent risk factors for a negative change in body temperature were transportation by ground ambulance (odds ratio = 3.20; 95% confidence interval, 1.06-11.49; P = .03) and being wet on initial presentation (odds ratio = 3.64; 95% confidence interval, 0.99-13.36; P = .05).

CONCLUSION

For adult patients transported from the scene of injury to a trauma center, active and passive warming measures, most notably the removal of wet clothing, were associated with a favorable outcome, whereas wet patients and ground ambulance transport were associated with an unfavorable outcome with respect to temperature.

Traumatisme et température

Le patient traumatisé est exposé à l’hypothermie. La mortalité des traumatisés hypothermes est multipliée par quatre ou cinq. Les interactions de l’hypothermie avec l’hémostase et le système cardiovasculaire sont délétères. Les effets sur la coagulation sont multiples et concourent directement à la surmortalité faisant de l’hypothermie une composante majeure de la « triade létale ». Les causes d’hypothermie chez le patient traumatisé sont multiples : 1) environnementales, le risque augmente quand la température ambiante diminue ; 2) cliniques, le risque augmente avec la gravité ; et aussi 3) thérapeutiques, par exemple par la perfusion de solutés à température ambiante. Une prise en charge optimale repose sur une mesure précoce et un monitorage continu de la température corporelle. L’objectif thérapeutique est de maintenir une température corporelle au moins égale à 36 °C. Limiter le déshabillage du patient, le protéger du froid avec une couverture de survie, l’installer rapidement dans une ambulance chauffée, recourir à des dispositifs de réchauffement actifs, perfuser des solutés réchauffés sont les éléments fondamentaux de la prise en charge d’un patient traumatisé, potentiellement hypotherme.
