All patients with truncal gunshot wounds deserve trauma team activation

Criteria for level 1 and level 2 trauma codes: Are pelvic ring injuries undertriaged?

AIM: To determine the association of unstable pelvic ring injuries with trauma code status.

METHODS: A retrospective review of all pelvic ring injuries at a single academic center from July 2010 to June 2013 was performed. The trauma registry was used to identify level 1 and level 2 trauma codes for each injury. The computed tomography scans in all patients were classified as stable or unstable using the Abbreviated Injury Scale. Pelvic injury classifications in level 1 and level 2 groups were compared. Patient disposition at discharge in level 1 and level 2 groups were also compared.

RESULTS: There were 108 level 1 and 130 level 2 blunt trauma admissions. In the level 1 group, 67% of pelvic injuries were classified as stable fracture patterns and 33% were classified as unstable. In the level 2 group, 62% of pelvic injuries were classified as stable fracture patterns and 38% were classified as unstable. level 1 trauma code was not associated with odds of having an unstable fracture pattern (OR = 0.83, 95%CI: 0.48-1.41, P = 0.485). In the level 1 group with unstable pelvic injuries, 33% were discharged to home, 36% to a rehabilitation facility, and 32% died. In the level 2 group with unstable pelvic injuries, 65% were discharged to home, 31% to a rehabilitation facility, and 4% died. For those with unstable pelvic fractures (n = 85), assignment of a level 2 trauma code was associated with reduced odds of death (OR = 0.07, 95%CI: 0.01-0.35, P = 0.001) as compared to being discharged to home.

CONCLUSION: Trauma code level assignment is not correlated with severity of pelvic injury. Because an unstable pelvis can lead to hemodynamic instability, these injuries may be undertriaged.

Trauma team activation criteria in managing trauma patients at an emergency room in Thailand

BACKGROUND

Trauma team activation (TTA) criteria were first implemented in the Emergency Department (ED) of Songklanagarind Hospital in 2009 to treat severe trauma patients.

PURPOSE

To determine the efficacy of the TTA criteria on the acute trauma care process in the ED and the 28-day mortality rate.

METHODS

A 1-year prospective cohort study was conducted at the ED. Trauma patients who were 18 years old and over who met the TTA criteria were enrolled. Demographic data, physiologic parameters, ED length of stay (EDLOS), and the injury severity score (ISS) were recorded. Multiple logistic regression was used to determine the factors affecting 28-day mortality. Institutional review board approval was obtained from the Prince of Songkla University.

RESULTS

A total of 80 patients (74 male and 6 female) were eligible with a mean age of 34.3 years old. Shock, penetrating torso injury, and pulse rate >120 beats per minute were the three most common criteria for trauma team consultation. At the ED, 9 patients (11.3 %) were non-survivors, 30 patients (37.5 %) needed immediate operation, and 41 patients (51.2 %) were admitted. All of the arrest patients died (p < 0.0001). The median time of EDLOS was 85 min: 68 min in the non-survivor group and 120 min in the survivor group (p = 0.028). The median ISS was 21.0 (1-75): 25.0 in the non-survivor group and 17.0 in the survivor group. When compared with pilot data prior to TTA implementation, the median time of EDLOS improved from 184 to 85 min and the 28-day mortality rate decreased from 66.7 to 46.3 %. The high ISS was a predictor of death.

CONCLUSION

The trauma team activation criteria improved acute trauma care in the ED which was demonstrated by the decreased EDLOS and mortality rate. A high ISS is the sole parameter predicting mortality.

Do pre-hospital trauma alert criteria predict the severity of injury and a need for an emergent surgical intervention?

OBJECTIVE

Efficient triage may have a major influence on mortality and morbidity as well as financial consequences. A continuous effort to improve this decision making process and update the trauma alert criteria is being made. However, criteria for determining the evacuation priority are not well developed. We performed a prospective study to evaluate which pre-hospital parameters identify major trauma victims with an emphasis on a need for emergent surgical procedures.

METHODS

A prospective cohort included 601 patients admitted to a level one trauma centre over a three months period. The pre-hospital trauma alert criteria were recorded and set as independent variables. All major surgical procedures were graded in real time as: emergent, urgent, or not urgent. The ISS was calculated after completion of all the diagnostic workup. Patients were classified as major trauma victims if their calculated ISS was 16 or greater, and those needed an urgent intervention or intensive care. The relative risks (RR) for major trauma and a need for an emergent operation were calculated.

RESULTS

243 (40%) patients were classified as having a major trauma. 39 (6.5%) patients required an emergent operative intervention: 24 for an active bleeding, 5 for a pericardial tamponade and 10 for an imminent cerebral herniation. Paramedic judgement and a penetrating injury to the trunk were the most common causes for over triage. However, a penetrating injury to the trunk had been the only clue that the victim needed an emergent operation in five cases. 128 patients had a pre-hospital Glasgow coma score (GCS) ≤ 12. Altered mental status was the most common and a significant predictor of both major trauma (RR of 3.00 with a 95% confidence interval (CI) of 1.98-4.53) and a need for an emergent operation (RR, 95% CI: 4.43, 2.28-8.58). Also, a systolic blood pressure ≤ 90 mmHg was highly associated with an emergent operation (RR, 95% CI: 11.69, 5.85-23.36).

CONCLUSION

For determining the evacuation priority, we suggest a triage system based on three major criteria: mental status, hypotension and a penetrating injury to the trunk. Overall, the set of trauma alert criteria system can be further simplified and enable better utilisation of resources.

Physiologically focused triage criteria improve utilization of pediatric surgeon-directed trauma teams and reduce costs

INTRODUCTION

Pediatric surgeon-directed trauma teams (STTs) provide lifesaving treatment but at a high cost. We used physiologically based criteria to improve STT utilization.

METHODS

We reviewed 152 consecutive STT activations at one center, comparing standard and physiologically focused criteria and 24-hour hospital costs/charges for overtriaged patients vs level 2 (emergency department managed) blunt trauma patients matched for age, Injury Severity Score (ISS), and necessity for operation.

RESULTS

Our cohort (73.0% male; 86.8% blunt; median age, 8.0 [interquartile range, 4.0-14.0] years) had 10 deaths (6.6%) and 18 (11.8%) emergent operations. Twenty-nine patients met neither standard nor physiologic criteria (group 1), 25 met standard but not physiologic criteria (overtriaged, group 2), and 98 met physiologic criteria (group 3). Group 3 had higher median ISS (19.0 [10.0-33.0] vs 10.0 [4.0-17.0] and 5.5 [5.0-16.75] for groups 1 and 2, P = .001), more intensive care unit admissions (67.2% vs 31.0% and 52.0%, P = .001), longer hospitalization (5.0 [3.0-9.25] days vs 3.0 [1.0-5.0] and 4.0 [2.0-5.0] days, P = .002), and all patients who died or required emergent operation (P < .001). Physiologic criteria maintained 100% sensitivity but improved specificity (49.2% vs 23.0%). Overtriaged patients (n = 18) had 78.2% higher charges ($4700; 95% confidence interval, 13.3%-180.1%; P = .013) and 53.4% higher costs ($800; 95% confidence interval, 1.8%-131.2%; P = .041) than level 2 patients (n = 259) after adjusting for age, ISS, and need for operation, largely because of computed tomography and emergency department charges (66% of overtriaged charges).

CONCLUSIONS

Physiologic STT activation criteria would have saved 25 activations, $20,000 in costs, and $120,000 in charges annually without compromising patient safety.

Precision of field triage in patients brought to a trauma centre after introducing trauma team activation guidelines

BACKGROUND

Field triage is important for regional trauma systems providing high sensitivity to avoid that severely injured are deprived access to trauma team resuscitation (undertriage), yet high specificity to avoid resource over-utilization (overtriage). Previous informal trauma team activation (TTA) at Ulleval University Hospital (UUH) caused imprecise triage. We have analyzed triage precision after introduction of TTA guidelines.

METHODS

Retrospective analysis of 7 years (2001-07) of prospectively collected trauma registry data for all patients with TTA or severe injury, defined as at least one of the following: Injury Severity Score (ISS) > 15, proximal penetrating injury, admitted ICU > 2 days, transferred intubated to another hospital within 2 days, dead from trauma within 30 days. Interhospital transfers to UUH and patients admitted by non-healthcare personnel were excluded. Overtriage is the fraction of TTA where patients are not severely injured (1-positive predictive value); undertriage is the fraction of severely injured admitted without TTA (1-sensitivity).

RESULTS

Of the 4,659 patients included in the study, 2,221 (48%) were severely injured. TTA occurred 4,440 times, only 2,002 of which for severely injured (overtriage 55%). Overall undertriage was 10%. Mechanism of injury was TTA criterion in 1,508 cases (34%), of which only 392 were severely injured (overtriage 74%). Paramedic-manned prehospital services provided 66% overtriage and 17% undertriage, anaesthetist-manned services 35% overtriage and 2% undertriage. Falls, high age and admittance by paramedics were significantly associated with undertriage. A Triage-Revised Trauma Score (RTS) < 12 in the emergency department reduced the risk for undertriage compared to RTS = 12 (normal value). Field RTS was documented by anaesthetists in 64% of the patients compared to 33% among paramedics.Patients subject to undertriage had an ISS-adjusted Odds Ratio for 30-day mortality of 2.34 (95% CI 1.6-3.4, p < 0.001) compared to those correctly triaged to TTA.

CONCLUSION

Triage precision had not improved after TTA guideline introduction. Anaesthetists perform precise trauma triage, whereas paramedics have potential for improvement. Skewed mission profiles makes comparison of differences in triage precision difficult, but criteria or the use of them may contribute. Massive undertriage among paramedics is of grave concern as patients exposed to undertriage had increased risk of dying.

Trauma team activation: simplified criteria safely reduces overtriage

BACKGROUND

Our current trauma triage system uses patient and scene variables within a 3-tiered trauma response system. Our purpose was to evaluate the accuracy of the current system and to identify the most reliable variables for trauma triage.

METHODS

This was a retrospective review at a level II trauma center. Multivariate logistic regression was used to identify independent predictors of the need for any urgent emergency department procedure or operative intervention. The current triage system was analyzed and compared with a proposed simplified system.

RESULTS

There were 1495 consecutive trauma admissions identified, the majority (88%) were blunt mechanism. Urgent emergency department interventions were required in 11%, and 4% required emergent surgery. Logistic regression demonstrated that prehospital Glasgow Coma Score <14 (odds ratio [OR] 9.7), hypotension (OR 3.3), altered respiratory effort (OR 4.6), and penetrating truncal injury (OR 10.8) independently predicted the need for urgent intervention (all P < .01). The current system undertriaged only 1% but overtriaged 51% of patients. A simplified triage system using these 4 variables significantly decreased overtriage and reliably identified patients with severe injury.

CONCLUSIONS

A simplified triage system using only highly predictive variables can safely decrease the high rate of overtriage of trauma patients.

[Personnel and structural requirements for the shock trauma room management of multiple trauma. A systematic review of the literature]

The aim of the study was the description of personal and structural preconditions essential for adequate diagnostic requirements and treatment in severely injured patients. Herein we give detailed information regarding both the composition and qualification of the trauma team and the activation criteria as well as instructions for the design of the emergency room and technical requirements. Clinical trials were systematically collected (MEDLINE, Cochrane, and hand searches) and classified into evidence levels (1 to 5 according to the Oxford system). The trauma team should consist of (trauma) surgeons, anesthesiologists, radiologists, and one to two nursing staff members of each department. The attending physician should be present within 20 min. Trauma team activation criteria are among others: high energy/velocity trauma, penetrating injuries, GCS < or =14, and intubation. The emergency room should be integrated in the emergency department with all technical equipment being permanently available for optimal diagnostic and therapeutic management. A CT scanner should be positioned nearby.Adequate management of severely injured patients requires optimal personal and structural conditions. High costs and additional personnel are justified by improved quality of treatment.
