TRAUMA RECEPTION AND RESUSCITATION

A Preliminary Trial of the Introduction of Computerized Decision Support to Assist Resuscitation of the Severely Injured in a Level 1 Trauma Centre in India

Injury from motor vehicle accidents remains a leading cause of death in India with increasing number of fatalities. Timely delivery of lifesaving interventions is critical for survival and in restoring physical functioning. As a part of the Australia India Trauma Systems Collaboration, the Trauma Reception and Resuscitation (TRR©)-computerized decision support system was implemented in a Level 1 Trauma Centre in India in order to determine whether this system would reduce the time in performing lifesaving interventions and improve vital sign data capture and documentation. This prospective cohort study at the Jai Prakash Narayan Apex Center, All India Institute of Medical Science, New Delhi, recruited a total of 106 participants into two groups: TRR© (76) and controls (30). During the first 30 min of resuscitation, the TRR© group recorded greater sets of vital signs in compared to the controls for medical records. More importantly, the real-time documentation of the vital signs for the TRR© group ensured accuracy for medical records. For lifesaving interventions, oxygen was administered in the TRR© group only if SpO2 < 93%, whereas oxygen was administered as standard of care in the controls. There was no statistical difference in the mean times to endotracheal intubation, intercostal catheter insertion or performance of emergency chest x-ray between the control and TRR© groups. Importantly however, these 3 comparable interventions were performed consistently within a smaller timeframe for patients receiving care with TRR© decision prompts. There was a greater variability in the time taken to perform lifesaving interventions in the control group in comparison to the clinicians assisted with computerized decision prompts. This preliminary study was not powered to measure difference in mortality and patient recruitment was limited to 8 am–5 pm when trained staff could attend to operating the TRR© system.

Development of an Instrument for Assessing Trauma Team Performance

Teamwork training is critical for patient safety and has been advocated for widespread application in many settings. A key challenge for evaluating teamwork training is measurement. Despite much effort, the team performance instruments reported thus far suffer from a variety shortcomings that prevent their wide application in assessing teams in real settings. Based on review of video recorded trauma team activities in real patient care, a multi-disciplinary research team developed an instrument based on observable behaviors (UMTOP). A set of video clips were reviewed by 6 subject matter experts who were requested to provide “descriptors” about the observed team activities. The 167 collated descriptors were combined to a reduced list, which was then sent to the subject matter experts for revision. The revised list was then categorized into 5 areas of team performance (task and clinical performance, leadership organization, teamwork organization, social environment, sterile precaution). UMTOP was developed to be a tradeoff among four criteria: ease of use, reliability, usefulness for team performance feedback, and speed of scoring. An initial assessment of reliability was conducted with surgeon and nursing reviewers.

Challenges developing evidence-based algorithms for the trauma reception and resuscitation project

A project based at the Alfred Emergency and Trauma Centre in Melbourne, Australia aimed to standardise trauma resuscitation, documentation and interventions by developing best practice algorithms. The primary study objective was to demonstrate a reduction in management errors using a real-time computer based algorithm (the study group) compared to the control group in an open randomised controlled interventional study. A baseline control group was also used for comparison with usual (current) practice. In order to examine the existing evidence and algorithms in trauma care, nine teams of emergency nurses and doctors were formed. Specific literature searches performed by each team revealed a paucity of evidence supporting clinical practice in the trauma setting for procedures. Subsequently, the multidisciplinary teams worked together and developed algorithms based on best practice. The process revealed three main areas of challenges in the development of algorithms: (i) clinical, (ii) research and (iii) nursing challenges. The completion of the project demonstrated benefits in the real-time computer based algorithm with a reduction in the error rate per patient from the baseline control group to the intervention study group (2.30 vs. 2.13, p=0.04) and error-free resuscitations increasing from 16% to 21.8% (p=.049). This project supported the implementation of a real-time computer based algorithm system with improved protocol compliance and reduced errors and morbidity.

The challenges of developing a trauma system for Indigenous people

Trauma systems have been shown to provide the best trauma care for injured patients. A trauma system developed for Indigenous people should take into account many factors including geographical remoteness and cultural diversity. Indigenous people suffer from a significant intentional and non-intentional burden of injury, often greater than non-Indigenous populations, and a public health approach in dealing with trauma can be adopted. This includes transport issues, prevention and control of intentional violence, cultural sensitization of health providers, community emergency responses, community rehabilitation and improving resilience. The ultimate aim is to decrease the trauma burden through a trauma system with which indigenous people can fully identify.

Problems and solutions arising during a study in visual semantics of the medical emergency team system

A study of the medical emergency team (MET) to explore communication within the team, leadership, handover, and MET resuscitation practice was performed using audiovisual recording in hospitals of Sydney South West Area Health Service, Sydney, Australia. In this article, we report on the process of data collection: the completion of 25 video recordings of MET calls across three of the six study hospitals. We describe how we gained entry into hospital environments to film events characterized by the unpredictability and uncertainties associated with resuscitating a patient and the strategies that we implemented during the fieldwork to develop and maintain rapport with both clinicians and managers. We describe how we addressed some of the practical constraints related to collecting audiovisual data at the point of acute care as well as their implications for the theoretical and methodological aspects of the study.

Survival following resuscitative thoracotomy for combined left ventricle and left atrium ruptures secondary to blunt trauma

Improvements in pre-hospital care and the development of integrated Trauma Systems have streamlined access for the severely injured to sophisticated, specialist Trauma Centre reception and resuscitation. We describe the initial care of a survivor of combined ruptures of the left ventricle and left atrium secondary to blunt injury. This case emphasises the contribution of such a Trauma System in achieving a favourable outcome for a severely injured trauma patient with injuries previously considered non-survivable.

Massive blood transfusion and trauma resuscitation

AIMS

To review the massive transfusion practice at a Level I adult Trauma Centre during initial trauma reception and resuscitation.

METHODS

All trauma patients presenting to The Alfred Emergency & Trauma Centre and receiving a transfusion of five units or more of packed red blood cells within 4h of presentation over a 26-month period were included in this study. Patient demographics, clinical characteristics, injuries, surgical management and volume of blood transfused were analysed with mortality as the primary endpoint. Initial clinical features and injuries predictive of massive transfusion were also analysed.

RESULTS

There were 119 patients who received a transfusion of five units or more of packed red blood cells (PRBCs) within 4h of presentation. The median Injury Severity Score of this group of patients was 34.0 (IQR 26-48) and mortality was 27.7%. The median number of packed red blood cell transfused was 8.0 (IQR 6-14) in the 1st 4h. Initial clinical features and injuries independently associated with a larger volume of blood transfused were initial hypotension, fractures of the pelvis, kidney injuries, initial acidaemia, and thrombocytopaenia. The Injury Severity Score, initial coagulopathy measured by APTT and the presence of head injuries were the independent predictors of mortality.

CONCLUSIONS

The volume of blood transfused during trauma resuscitation was not found to be an independent predictor of mortality. Prospective studies into transfusion practice and clinical features of patients during the trauma resuscitation phase requiring massive transfusion are needed to establish evidence-based guidelines for massive transfusion.
