Trauma facilities in Denmark - a nationwide cross-sectional benchmark study of facilities and trauma care organisation

[Composition of trauma room teams : Reality experienced in 12 transregional trauma centers]

BACKGROUND

The provision of specialized trauma teams for the care of severely injured patients is mandatory according to the requirements of the S3 guidelines polytrauma and the composition is determined by the White Book Medical Care of the Severely Injured (Weißbuch Schwerverletztenversorgung). In each level of care the basic resuscitation room team is composed of four disciplines: orthopedics and trauma surgery, anesthesia, radiology and emergency medicine in the emergency department.

MATERIAL AND METHODS

A prospective, multicenter observational study was conducted in 12 supraregional trauma centers in Germany and Switzerland, where a total of 3753 patients were treated in the emergency department following accidents. Amongst them 964 patients (26%) were treated after prior trauma team activation.

RESULTS

In 94.7% of the trauma room care instances all 4 required disciplines were present, with an average of 6.6 individuals involved in the trauma room care. The 48‑h mortality rate was 3% among patients receiving trauma room care. In all deceased patients, all four disciplines were present during the trauma room care. At least one or more high-risk criteria for serious injuries were present in 40.8% of the patients. In these cases, a complete team consisting of all 4 disciplines was involved in 97.7% of the care instances.

CONCLUSION

In nearly 98% of cases where high-risk criteria for serious injuries (category A activation criteria) all 4 required disciplines were present in the trauma room for patient care. This was associated with an average resource commitment of 6.6 individuals. The absence of one or more disciplines in trauma room care does not appear to significantly affect early mortality in the severely injured.

Pediatric trauma over a decade: demographics, mechanisms of injury, and mortality at a major Danish trauma center-a retrospective cohort study

BACKGROUND

In recent decades, the number of fatal accidents among children and adolescents has declined. Nevertheless, trauma remains a significant cause of death among children and adolescents in high-income countries, despite significant advancements in prevention and care. Pediatric trauma patients differ substantially from adults in terms of their physiology, anatomy, and daily activities; therefore, they show distinct injury patterns and require different care. The aim of this study was to investigate mortality from trauma in pediatric patients admitted by trauma team activation at the Aarhus University Hospital Trauma Center (AUH-TC) in a highly developed country with exceptionally low child mortality, where trauma is a leading cause of death in this age-group. By evaluating trends in demographics, mechanisms of injury, injury severity, and outcomes, this study aims to provide insights into trauma care and outcomes.

METHODS

This retrospective cohort study included 1,037 pediatric patients (< 18 years old) consecutively admitted by trauma team activation from 1 January 2011 to 31 December 2021. The pediatric patients accounted for 14% of the total trauma population, which consisted of 7307 patients in total. Data on demographics, Injury Severity Score (ISS), mechanism of injury, and 30-day mortality were analyzed. Descriptive statistics were reported.

RESULTS

Boys accounted for 58% of the patients (n = 595). Falls were the mechanism of injury in 47% (n = 308) of children under 13 years old, while traffic-related injuries accounted for 38% (n = 139) of adolescents aged 14-17 years. Severe injuries (ISS > 15) were associated with traffic accidents in 25% of cases. The number of traumas peaked on weekends (71%) and during the spring/summer (29%). The ISS was greater than 15 in 13% (n = 130) of the patients, and the overall 30-day mortality rate was 1.6% (n = 17).

CONCLUSIONS

This study found no significant change in pediatric trauma incidence at AUH-TC over a decade. In Denmark, the few children with an ISS above 15 are predominantly injured in traffic accidents, with risk increasing with age. There was a low incidence of patients with an ISS above 15, and mortality rates were lower than in similar studies. These findings on injury patterns and severity may aid in risk assessment, accident prevention, and hospital resource planning. Further research with extended follow-up is recommended to assess potential trends in trauma mechanisms over time.

Adherence to national trauma triage criteria in Norway: a cross-sectional study

BACKGROUND

Norwegian hospitals employed individual trauma triage criteria until 2015 when nationwide criteria were implemented. There is a lack of empirical evidence regarding adherence to Norwegian national criteria for activation of the trauma team (NTrC) and the decision-making processes regarding trauma team activation (TTA) within Norwegian trauma hospitals. The objectives of this study were to investigate institutional adherence to the NTrC and to investigate similarities and differences in the decision-making process leading to TTA in Norwegian trauma hospitals.

METHODS

A digital semi-structured questionnaire regarding adherence to criteria, TTA decision-making and criteria documentation was distributed to all Norwegian trauma hospitals (n = 38) in the spring of 2022. Contact details of trauma coordinators and registrars were provided by the Norwegian Trauma Registry secretariat. Follow-up telephone interviews were conducted at the investigator's discretion in cases of non-respondents or need to clarify answers.

RESULTS

Thirty-eight trauma hospitals were invited to answer the survey, where 35 hospitals responded (92%), making 35 the denominator of the results. Thirty-four (97.1%) hospitals stated that they followed NTrC. Thirty-three (94.3%) of the responding hospitals provided documentation of their criteria in use, of which twenty-eight (80%) of responding hospitals adhered to the NTrC. Three (8.6%) hospitals employed a tiered TTA approach with different sized teams. In addition four hospitals (11.4%) used specialized teams to meet the needs of defined patient groups (e.g. geriatric patients, traumatic brain injury). Twenty-one (60%) of the responding hospitals had written guidelines on who could perform TTA and in 18 hospitals (51.4%) TTA could be performed by pre-hospital personnel. Twenty-three (65.7%) of the hospitals documented which criteria that were used for TTA.

CONCLUSION

There is good adherence to the national criteria for activation of the trauma team among Norwegian trauma hospitals after implementation of national guidelines. Individual hospitals argue the use of certain local criteria and trauma team activation decision-making processes to increase their precision in specific patient populations and demographics. Further steps should be done to reduce the variation in TTA decision-making processes among hospitals and improve documentation quality.

The use of specific coordination behaviours to manage information processing and task distribution in real and simulated trauma teamwork: an observational study

Trauma teams handle severely injured patients under high temporal demands and need to coordinate and achieve collaborative decision-making and task execution through communication. Specific coordination and communication behaviours are taught in simulation training to enhance team performance. An examination of the role and nature of communication could increase the understanding of educational possibilities and assess the validity of in situ simulation on behalf of communication. Our study aim was to describe the relative use of communication within information and task management, the use of coordinating behaviours, and the use of talking to the room and closed-loop communication in in-real-life trauma assessment and in the simulated domain. We video-recorded all verbal communicative events in four real-world trauma teams and four teams during simulation training. The analysis showed that although the teamwork was task-oriented, information management dominated task management at 64% of all the utterances in-real-life and 68% during simulation. In-real-life, information management was dominated by the codes "request information" (24%) and "confirmation" (21%), whereas "task distribution" (43%) was most frequently used for task management. The only difference between domains was that "give information after request" represented a smaller proportion of the utterances in-real-life compared to simulation (p ≤ 0.001). Talking to the room was primarily used by the teams in both domains to provide information without request and to delegate tasks. Closed-loop communication was used at a low frequency, 3.6% in-real-life, but was significantly higher, 7.7%, in simulation training. We suspect that this outcome reflects the Hawthorne effect. In the simulations, greater information delivery was provided in response to questions, probably accounting for instructor information. Our results may be valuable for research on trauma team behaviour in a simulated environment to draw conclusions about similar activities in-real-life.

Traumatic cardiac arrest - a nationwide Danish study

BACKGROUND

Cardiac arrest following trauma is a leading cause of death, mandating urgent treatment. This study aimed to investigate and compare the incidence, prognostic factors, and survival between patients suffering from traumatic cardiac arrest (TCA) and non-traumatic cardiac arrest (non-TCA).

METHODS

This cohort study included all patients suffering from out-of-hospital cardiac arrest in Denmark between 2016 and 2021. TCAs were identified in the prehospital medical record and linked to the out-of-hospital cardiac arrest registry. Descriptive and multivariable analyses were performed with 30-day survival as the primary outcome.

RESULTS

A total of 30,215 patients with out-of-hospital cardiac arrests were included. Among those, 984 (3.3%) were TCA. TCA patients were younger and predominantly male (77.5% vs 63.6%, p =  < 0.01) compared to non-TCA patients. Return of spontaneous circulation occurred in 27.3% of cases vs 32.3% in non-TCA patients, p < 0.01, and 30-day survival was 7.3% vs 14.2%, p < 0.01. An initial shockable rhythm was associated with increased survival (aOR = 11.45, 95% CI [6.24 - 21.24] in TCA patients. When comparing TCA with non-TCA other trauma and penetrating trauma were associated with lower survival (aOR: 0.2, 95% CI [0.02-0.54] and aOR: 0.1, 95% CI [0.03 - 0.31], respectively. Non-TCA was associated with an aOR: 3.47, 95% CI [2.53 - 4,91].

CONCLUSION

Survival from TCA is lower than in non-TCA. TCA has different predictors of outcome compared to non-TCA, illustrating the differences regarding the aetiologies of cardiac arrest. Presenting with an initial shockable cardiac rhythm might be associated with a favourable outcome in TCA.

Models of acute care for injured older patients-Australia and New Zealand practice

INTRODUCTION

The epidemiology of injured patients has changed, with an increasing predominance of severe injury and deaths in older (65 years and above) patients after low falls. There is little evidence of the models of care that optimise outcomes for injured older patients. This study aims to describe clinician perspectives of existing models of acute care for injured older patients in Australia and New Zealand.

METHODS

This cross-sectional online survey of healthcare professionals (HCP) managing injured older patients in Australia or New Zealand hospitals was conducted between November 2nd and December 12th, 2020. Recruitment was via survey link and snowball sampling to professional organisations and special interest groups via email and social media. HCP were asked, using a Likert scale, how likely four typical case vignettes were to be admitted to one of twelve options for ongoing care. Additional questions explored usual care components.

RESULTS

Participants (n=157) were predominantly Australian medical professionals in a major trauma service (MTS) or metropolitan hospital. The most common age defining "geriatric" was aged 65 years and older (43%). HCP described variability in the models and components of acute care for older injured patients in Australia and New Zealand. As a component of care, cognitive, delirium and frailty screening are occurring (60%, 61%, 46%) with HCP from non-major trauma services (non-MTS) reporting frailty and cognitive impairment screening more likely to occur in the emergency department (ED). Access to an acute pain service was more likely in a MTS. Participants described poor likelihood of a geriatrician (highest 16%) or physician (highest 12%) review in ED CONCLUSION: Despite a low response rate, HCP in Australia and New Zealand describe variability in acute care pathways for injured older patients. Given the change in epidemiology of injury towards older patients with low force mechanisms, models of acute injury care should be evaluated to define a cost-effective model and components of care that optimise patient-centred outcomes relevant to injured older patients. HCP described some factors they perceive to determine care, and outcomes of variability, offering guidance for future research and resource allocation in the Australia and New Zealand trauma system.

Ten‐year trends of adult trauma patients in Central Denmark Region from 2010 to 2019: A retrospective cohort study

Background

Trauma causes significant economic and societal burdens, and the trauma patient population and their prognosis change over time. This study aims to analyze 10‐year trends of trauma patients at a major trauma center in Central Denmark Region.

Methods

Five thousand three hundred and sixty‐six patients aged ≥16 years with Injury Severity Score (ISS) > 0 admitted by trauma team activation at a major trauma center between January 1, 2010, and December 31, 2019, were included. An annual percent change with a 95% confidence interval was used to estimate trends in the mechanism of injuries. Multiple logistic regression with mortality as the outcome was adjusted for age, sex, and ISS. Admission year was used as continuous variable in logistic regressions.

Results

The median age increased from 37 in 2010 to 49 in 2019, and the proportion of patients aged ≥65 doubled. The annual incidence of minor injuries (ISS 1–15) decreased from 181.3/10⁵ inhabitants in 2010 to 112.7/10⁵ in 2019. Severe injuries (ISS > 15) increased from 10.1/10⁵ inhabitants in 2010 to 13.6/10⁵ in 2019. The proportion of patients with ISS > 15 increased from 18.1% in 2010 to 31.1% in 2019. Multivariable logistic regression indicates lower 30‐day mortality for all trauma patients over the study period when adjusting for age, sex, and ISS (odds ratio: 0.94, 95% CI: 0.90–0.99). The 30‐day mortality for severely injured patients with ISS > 15 seems to decrease during the study period when adjusting for age, sex, and ISS (Odds ratio: 0.92, 95% CI: 0.87–0.97). Fall injuries increased by 4.1% annually (95% CI: 2.3%–6.1%).

Conclusions

Ten‐year trends of trauma patients at a major trauma center show an increasing median age, injury severity, and number of fall injuries. The 30‐day mortality of trauma patients decreased slightly for both minor injuries and severe injuries when adjusting for age, sex, and injury severity.

Point-of-care ultrasound induced changes in management of unselected patients in the emergency department - a prospective single-blinded observational trial

Background

Point-of-Care ultrasound (POCUS) changes the management in specific groups of patients in the Emergency Department (ED). It seems intuitive that POCUS holds an unexploited potential on a wide variety of patients. However, little is known about the effect of ultrasound on the broad spectrum of unselected patients in the ED. This study aimed to identify the effect on the clinical management if POCUS was applied on unselected patients. Secondarily the study aimed to identify predictors of ultrasound changing management.

Methods

This study was a blinded observational single center trial. A basic whole body POCUS protocol was performed in extension to the physical examination. The blinded treating physicians were interviewed about the presumptive diagnosis and plan for the patient. Subsequently the physicians were unblinded to the POCUS results and asked to choose between five options regarding the benefit from POCUS results.

Results

A total of 403 patients were enrolled in this study. The treating physicians regarded POCUS examinations influence on the diagnostic workup or treatment as following: 1) No new information: 249 (61.8%), 2) No further action: 45 (11.2%), 3) Further diagnostic workup needed: 52 (12.9%), 4) Presumptive diagnosis confirmed 38 (9.4%), and 5) Immediate treatment needed: 19 (4.7%). Predictors of beneficial ultrasound were: (a) triage > 1, (b) patient comorbidities (cardiac disease, hypertension or lung disease), or (c) patients presenting with abdominal pain, dyspnea, or syncope.

Conclusion

POCUS was found to be potentially beneficial in 27.0% of all patients. High triage score, known cardiac disease, hypertension, pulmonary diseases, a clinical presentation with abdominal pain, dyspnea, or syncope are predictors of this. Future research should focus on patient-important outcomes when applying POCUS on these patients.

Trial registration

The trail was registered prior to patient inclusion with the Danish Data Protection Agency (https://www.datatilsynet.dk/ Case no: 1–16–02-603-14) and Clinical Trials (www.clinicaltrials.gov/ Protocol ID: DNVK1305018).

Improved medical treatment could explain a decrease in homicides with a single stab wound

Since the 1990s, there has been a reduction in the homicide rate in Denmark and other Western countries. Our hypothesis is that part of the decrease in the sharp force homicide rate can be explained by better and faster medical treatment over time, and we explore this via stab wound homicides, the largest group of homicides in Denmark. To investigate our hypothesis we undertook an epidemiological study of 428 stab wound homicides in Denmark 1992-2016 based on autopsy reports with registration of stab wounds, quantification of injury severity, treatment intensity and survival time. During 1992-2016, there was a significant reduction in the annual number of victims with a single stab wound, but no reduction in victims with multiple stab wounds. Victims with single stab wounds reached the hospital more often, survived longer and had less severe injuries (New Injury Severity Score (NISS)) than victims with multiple stab wounds. Higher NISS correlated with shorter survival time for all the stab wound victims and for the subgroup that underwent medical treatment. During the 25-year study period, the proportion of victims who underwent surgery before dying increased threefold. The victims in the first half of the study period had shorter survival times than the victims in the last half. We concluded that better and faster medical treatment could partly be responsible for the observed decrease in the number of single stab wound homicides and thereby possibly also in the total number of stab wound homicides.

Trauma Response Nurse: Bringing Critical Care Experience and Continuity to Early Trauma Care

Multitrauma patients can benefit significantly from specialized care. Prior to mid-2016, this hospital's trauma team did not include a surgical intensive care unit (SICU) nurse. As the value of bringing this expertise to the patient upon arrival was realized, the role of the trauma response nurse (TRN) was developed. The TRN role was designed to provide a dedicated SICU nurse to care for trauma patients from emergency department (ED) arrival through disposition. The integration of the TRN role into the trauma team sought to improve quality and safety, as well as communication and collaboration, and enhance continuity of care. The primary responsibilities of the TRN were to assist with clinical interventions, transport patients fromthe ED to tests and procedures, and assume care through disposition. Additional TRN duties included education, community outreach, and performance improvement. TRNs now respond to all trauma activations that occur on weekday day shift. This role has improved collaboration between nursing disciplines, improved the overall function of the trauma team, and enhanced the safety of trauma patients during transport. TRNs make valuable contributions to the education and outreach missions of the trauma program and ensure that patients are receiving the highest level of trauma care.
