Recommendations for uniform reporting of data following major trauma--the Utstein style. An International Trauma Anaesthesia and Critical Care Society (ITACCS) initiative

Utstein Style for emergency care - the first 30 years

BACKGROUND

Utstein Abbey near Stavanger in Norway, hosted a meeting in 1990 on guidelines for the uniform reporting of data from out-of-hospital cardiac arrest. In this paper we describe the last 30 years of the Utstein style.

METHODS

A systematic literature search identified publications from Utstein-style meetings or groups using the Utstein format.

RESULTS

30 outputs were found, describing primarily resuscitation structure, process and outcome measures. They originated from all over the world and from multiple medical disciplines. Some were co-published in multiple journals.

CONCLUSIONS

The meeting at Utstein Abbey in 1990 has had a sustained and far-reaching impact, particularly in resuscitation science, implementation and outcomes. The Utstein format will continue to evolve following the key principles from the original meeting and with the ultimate aim of improving patient care and outcomes.

Predictive Factors for Massive Transfusion in Trauma: A Novel Clinical Score from an Italian Trauma Center and German Trauma Registry

Early management of critical bleeding and coagulopathy can improve patient survival. The aim of our study was to identify independent predictors of critical bleeding and to build a clinical score for early risk stratification. A prospective analysis was performed on a cohort of trauma patients with at least one hypotensive episode during pre-hospital (PH) care or in the Emergency Department (ED). Patients who received massive transfusion (MT+) (≥4 blood units during the first hour) were compared to those who did not (MT−). Hemodynamics, Glagow Coma Score (GCS), diagnostics and blood tests were evaluated. Using multivariate analysis, we created and validated a predictive score for MT+ patients. The predictive score was validated on a matched cohort of patients of the German Trauma Registry TR-DGU. One hundred thirty-nine patients were included. Independent predictors of MT+ included a prehospital (PH) GCS of 3, PH administration of tranexamic acid, hypotension and tachycardia upon admission, coagulopathy and injuries with significant bleeding such as limb amputation, hemoperitoneum, pelvic fracture, massive hemothorax. The derived predictive score revealed an area under the curve (AUC) of 0.854. Massive transfusion is essential to damage control resuscitation. Altered GCS, unstable hemodynamics, coagulopathy and bleeding injuries can allow early identification of patients at risk for critical hemorrhage.

Template for uniform reporting of emergency department measures, consensus according to the Utstein method

OBJECTIVE

To develop a template for uniform reporting of standardized measuring and describing of care provided in the emergency department (ED).

METHODS

An international group of experts in emergency medicine, with broad experience from different clinical settings, met in Utstein, Norway. Through a consensus process, a limited number of measures that would accurately describe an ED were chosen and a template was developed.

RESULTS

The final measures to be reported and their definitions were grouped into six categories: Structure, Staffing and governance, Population, Process times, Hospital and healthcare system and Outcomes. The template for Utstein-style uniform reporting is presented.

CONCLUSION

The suggested template is intended for use in studies carried out in EDs to improve comparability and knowledge translation.

Prospective Evaluation of Cardiopulmonary Resuscitation Performed in Dogs and Cats According to the RECOVER Guidelines. Part 1: Prognostic Factors According to Utstein-Style Reporting

Factors associated with positive cardiopulmonary resuscitation (CPR) outcomes defined according to the veterinary Utstein-style CPR reporting guidelines have not been described since implementation of the Reassessment Campaign on Veterinary Resuscitation (RECOVER) CPR clinical guidelines in 2012. The aims of this study were to assess factors associated with positive CPR outcomes at a U.S. veterinary teaching hospital, to re-evaluate these factors since implementation of the RECOVER guidelines compared to reported factors prior to their publication, and to identify potential additional factors since guideline publication. One-hundred and seventy-two dogs and 47 cats that experienced cardiopulmonary arrest (CPA) and had CPR performed were prospectively included in this observational study. Supervising clinicians were asked to complete a data form on CPR events immediately following completion of CPR efforts. Multivariable logistic regression was used to evaluate the effect of twenty hospital, animal, and arrest variables on the three patient outcomes “any return of spontaneous circulation (ROSC),” “sustained ROSC,” and survival to hospital discharge. Cats had significantly higher odds to achieve any ROSC [OR (95%CI) 2.72 (1.12–6.61), p = 0.028] and survive to hospital discharge than dogs [OR (95%CI) 4.87 (1.52–15.58), p = 0.008]. Patients had significantly lower odds of achieving any ROSC if CPA occurred during nighttime hours [OR (95%CI) nighttime = 0.52 (0.27–0.98), p = 0.043], and higher odds if CPA was witnessed [OR (95%CI) 3.45 (1.57–7.55), p = 0.002], if less people were involved in CPR efforts [OR (95%CI) 0.8 (0.66–0.96), p = 0.016], if pulses were palpable during CPR [OR (95%CI) 9.27 (4.16–20.63), p < 0.0005], and if an IV catheter was already in place at the time of CPA [OR (95%CI) 5.07 (2.12–12.07), p = 0.0003]. Odds for survival to hospital discharge were significantly higher if less people were involved in CPR efforts [OR (95%CI) 0.65 (0.46–0.91), p = 0.013] and for patients of the anesthesia service [OR (95%CI) 14.82 (3.91–56.17), p = 0.00007]. Overall, factors associated with improved CPR outcomes have remained similar since incorporation of RECOVER guidelines into daily practice. Witnessed CPA events and high-quality CPR interventions were associated with positive patient outcomes, emphasizing the importance of timely recognition and initiation of CPR efforts. An optimal CPR team size has yet to be determined.

Effect of Pre-Hospital Intubation in Patients with Severe Traumatic Brain Injury on Outcome: A Prospective Cohort Study

Secondary injuries are associated with bad outcomes in the case of severe traumatic brain injury (sTBI). Patients with a Glasgow Coma Scale (GCS) < 9 should undergo pre-hospital intubation (PHI). There is controversy about whether PHI is beneficial. The aim of this study was to estimate the effect of PHI in patients after sTBI. A multicenter, prospective cohort study was performed in Switzerland, including 832 adults with sTBI. Outcomes were death and impaired consciousness at 14 days. Associations between risk factors and outcomes were assessed with univariate and multivariate Cox models for survival, and univariate and multivariate regression models for impaired consciousness. Potential risk factors were age, GCS on scene, pupil reaction, Injury Severity Score (ISS), PHI, oxygen administration, and type of admission to trauma center. Age, GCS on scene < 9, abnormal pupil reaction and ISS ≥ 25 were associated with mortality. GCS < 9 and ISS ≥ 25 were correlated with impaired consciousness. PHI was overall not associated with short-term mortality and consciousness. However, there was a significative interaction with PHI and major trauma. PHI improves outcome from patients with sTBI and an ISS ≥ 25.

Major trauma registry of Navarre (Spain): the accuracy of different survival prediction models

OBJECTIVE

To determine which factors predict death among trauma patients who are alive on arrival at hospital.

METHODS

Design prospective cohort study method. Data were collected on 378 trauma patients who were initially delivered by the emergency medical services of Navarre (Spain) with multiple injuries with a new injury severity score of 15 or more in 2011-2012. These data related to age, gender, presence of premorbid conditions, abbreviated injury score, injury severity score, new injury severity score (NISS), revised trauma score (RTS), and prehospital and hospital response times. Bivariate analysis was used to show the association between each variable and time until death. Mortality prediction was modeled using logistic regression analysis.

RESULTS

The variables related to the end result were the age of the patient, associated comorbidity, NISS, and hospital RTS. Two models were formulated: in one, the variables used were quantitative, while in the other model these variables were converted into dichotomous qualitative variables. The predictive capability of the two models was compared with the trauma and injury severity score using the area under the curve. The predictive capacities of the three models had areas under the curve of 0.93, 0.88, and 0.87. The response times of the Navarre emergency services system, measured as the sum of the time taken to reach the hospital (median time of 65 min), formulate computed tomography (46 min), and perform crucial surgery (115 min), when required, were not taken into account.

CONCLUSION

Age, premorbid conditions, hospital RTS, and NISS are significant predictors of death after trauma. The time intervals between the accident and arrival at the hospital, arrival at the hospital and the first computed tomography scan or the first crucial emergency intervention, do not appear to affect the risk of death.

Pediatric sedation: a global challenge

Pediatric sedation is a challenge which spans all continents and has grown to encompass specialties outside of anesthesia, radiology and emergency medicine. All sedatives are not universally available and local and national regulations often limit the sedation practice to specific agents and those with specific credentials. Some specialties have established certification and credentials for sedation delivery whereas most have not. Some of the relevant sedation guidelines and recommendations of specialty organizations worldwide will be explored. The challenge facing sedation care providers moving forward in the 21st century will be to determine how to apply the local, regional and national guidelines to the individual sedation practices. A greater challenge, perhaps impossible, will be to determine whether the sedation community can come together worldwide to develop standards, guidelines and recommendations for safe sedation practice.

A 5-year Profile of Trauma Admissions to the Surgical Intensive Care Unit of a Tertiary Hospital in Singapore

Introduction: This retrospective pilot study provides information on trauma admissions to the Surgical Intensive Care Unit (SICU) of a tertiary hospital in Singapore. The aim was to use the data collected to generate awareness and interest in this area. The authors also wish to use the information to advocate subsequent in-depth collection and analysis of data and the development of a Trauma Registry. As this was a pilot study, the data collected were by no means exhaustive and only descriptive analysis was applied. Materials and Methods: Trauma admissions to the SICU for the period between January 2001 and December 2005 were identified from the admissions logbook maintained in the unit. The physical case-notes or electronic-records for the identified cases were retrieved and the relevant data and parameters were entered into the data collection sheet. Descriptive analysis was applied to the data collected. Results: A total of 503 cases over the 5-year period fulfilled our criteria. Motor vehicle accidents were the greatest contributor of trauma admissions to the SICU (53%). The length of stay (LOS) in the unit ranged from 1 to 59 days. The anatomical area most frequently injured was the head (68%). Out of the 132 mortalities, male patients accounted for 84%. Two-thirds (67%) of injury-related mortality occurred in young patients aged less than 45 years. Motor vehicle accidents accounted for nearly half (47%) of injury-related mortality. Motorcyclists accounted for almost half (46%) of motor vehicle accident deaths. Conclusion: The preponderance of young people involved in motor vehicle accidents with head injuries has a large impact on society and on the hospital workload. The authors hope that this pilot study will generate awareness and interest in the area of trauma injuries. They recommend that a nationwide trauma registry be established to look closer into this “disease”, as other developed countries have done. Key words: Critical care, Data, Registry

The Toronto prehospital hypertonic resuscitation-head injury and multi organ dysfunction trial (TOPHR HIT)--methods and data collection tools

Background

Clinical trials evaluating the use of hypertonic saline in the treatment of hypovolemia and head trauma suggest no survival superiority over normal saline; however subgroup analyses suggest there may be a reduction in the inflammatory response and multiorgan failure which may lead to better survival and enhanced neurocognitive function. We describe a feasibility study of randomizing head injured patients to hypertonic saline and dextran vs. normal saline administration in the out of hospital setting.

Methods/Design

This feasibility study employs a randomized, placebo-controlled design evaluating normal saline compared with a single dose of 250 ml of 7.5% hypertonic saline in 6% dextran 70 in the management of traumatic brain injuries. The primary feasibility endpoints of the trial were: 1) baseline survival rates for the treatment and control group to aid in the design of a definitive multicentre trial, 2) randomization compliance rate, 3) ease of protocol implementation in the out-of-hospital setting, and 4) adverse event rate of HSD infusion.

The secondary objectives include measuring the effect of HSD in modulating the immuno-inflammatory response to severe head injury and its effect on modulating the release of neuro-biomarkers into serum; evaluating the role of serum neuro-biomarkers in predicting patient outcome and clinical response to HSD intervention; evaluating effects of HSD on brain atrophy post-injury and neurocognitive and neuropsychological outcomes.

Discussion

We anticipate three aspects of the trial will present challenges to trial success; ethical demands associated with a waiver of consent trial, challenging follow up and comprehensive accurate timely data collection of patient identifiers and clinical or laboratory values. In addition all the data collection tools had to be derived de novo as none existed in the literature.

Study designs and evaluation models for emergency department public health research

Abstract Public health research requires sound design and thoughtful consideration of potential biases that may influence the validity of results. It also requires careful implementation of protocols and procedures that are likely to translate from the research environment to actual clinical practice. This article is the product of a breakout session from the 2009 Academic Emergency Medicine consensus conference entitled "Public Health in the ED: Screening, Surveillance, and Intervention" and serves to describe in detail aspects of performing emergency department (ED)-based public health research, while serving as a resource for current and future researchers. In doing so, the authors describe methodologic features of study design, participant selection and retention, and measurements and analyses pertinent to public health research. In addition, a number of recommendations related to research methods and future investigations related to public health work in the ED are provided. Public health investigators are poised to make substantial contributions to this important area of research, but this will only be accomplished by employing sound research methodology in the context of rigorous program evaluation.

Pre-hospital trauma care

The chain of survival in outcome from major trauma is equally as important as its well established concept in survival from cardiac arrest. Preventive measures have been shown to be an effective means of reducing death from trauma, and the standard of pre-hospital care for those surviving the primary injury is improving in many trauma systems. The optimal pre-hospital interventions are still debated, but evidence suggests that patients with severe head injury in particular will benefit significantly from pre-hospital rapid-sequence intubation and field stabilization, whereas those with penetrating injury require rapid evacuation to hospital with minimal intervention. Pre-hospital asystole from trauma has a universally poor outcome. When delivering appropriate care, several helicopter-based systems have shown improvements in outcome compared with ground-based systems. The International Liaison Committee on Resuscitation recently published guidelines on resuscitation, with particular relevance to pre-hospital trauma care. The importance of bystander cardiopulmonary resuscitation, oxygenation, and the avoidance of iatrogenic morbidity are stressed.

Acute trauma with multiple injuries

Trauma with multiple injuries is a leading cause of death. It presents a diversity of challenges and requires many healthcare workers to care for its victims. Advances continue in the organization of pre-hospital care, the techniques of trauma surgery and critical care, and understanding the pathophysiology of traumatic injuries.

Assessing quality of care in a trauma referral center: benchmarking performance by TRISS-based statistics or by analysis of stratified ISS data?

BACKGROUND

Using prospectively collected data from Ulleval University Hospital in Norway, standard TRISS-based methods with case mix correction were compared with analysis based on ISS stratified data.

METHODS

Reference data were The Major Trauma Outcome Study (MTOS) controlled sites, used for calculation of AIS 90 based TRISS coefficients. Present TRISS convention requires RTS scoring on hospital admission, excluding many severely injured patients intubated before arrival. Therefore, all Ulleval patients were RTS scored using prehospital data if needed.

RESULTS

There was 6.6% of MTOS controlled sites patients (mortality rate 26.7%) that had been excluded before estimation of TRISS coefficients because of lack of data for Ps calculation. Analyses based on ISS stratified data included these patients and indicated significant better performance at Ulleval for blunt, but not for penetrating trauma. No TRISS-based analysis detected this difference.

CONCLUSIONS

The RTS convention should be changed to reduce patient exclusion. Presently, stratified ISS based data should also be analyzed.

The Trauma Registry as a Statewide Quality Improvement Tool

BACKGROUND

Trauma registries have been developed to describe the pattern of trauma and trauma workload, provide data for research, and to demonstrate changes in patient outcomes. Quality improvement using trauma registries at a system-wide level has been difficult to achieve. In Victoria, Australia, a statewide trauma system and trauma registry has been established to monitor and feedback the process of management and outcomes of major trauma patients across all healthcare providers.

METHODS

The development and implementation of the Victorian State Trauma Registry (VSTR), including its role as a quality monitoring tool and results from the first 2 years of operation, are provided.

RESULTS

More than 80% of major trauma patients are being managed at major trauma services and standardized death rates are comparable with international standards. Quality indicators identify some areas for improvement.

CONCLUSION

VSTR data indicate that the statewide trauma system is working well and provides a method for ongoing monitoring and trauma care feedback.

“Utstein style” spreadsheet and database programs based on Microsoft Excel® and Microsoft Access® software for CPR data management of in-hospital resuscitation

In 1997, The American Heart Association in association with representatives of the International Committee on Resuscitation (ILCOR) published recommended guidelines for reviewing, reporting and conducting in-hospital cardiopulmonary resuscitation (CPR) outcomes using the "Utstein style". Using these guidelines, we developed two Microsoft Office based database management programs that may be useful to the resuscitation community. We developed a user-friendly spreadsheet based on MS Office Excel. The user enters patient variables such as name, age, and diagnosis. Then, event resuscitation variables such as time of collapse and CPR team arrival are entered from a "code flow sheet". Finally, outcome variables such as patient condition at different time points are recorded. The program then makes automatic calculations of average response times, survival rates and other important outcome measurements. Also using the Utstein style, we developed a database program based on MS Office Access. To promote free public access to these programs, we established at a website. These programs will help hospitals track, analyze, and present their CPR outcomes data. Clinical CPR researchers might also find the programs useful because they are easily modified and have statistical functions.
