Emergency department physicians can easily underestimate the severity of damage underlying the innocuous looking high-pressure injection injuries. These work-related injuries lead to significant lifelong morbidity as functionality is compromised in most cases, even after recovery due to high rates of amputation. Hence it is important to consider all high-pressure injection injuries as surgical emergencies. A detailed case history including pressure of the instrument, nature of the material, volume injected, angle of injection and time since injury should guide the treatment. Immediate debridement, antibiotic therapy and postoperative care are essential in all cases. Success of the treatment largely depends on early initiation of the therapy. Relying exclusively on non-surgical interventions may not be favorable in most cases as the injected material will continue damaging the internal tissues. Patients have to undergo a long recovery period with physiotherapy to regain the functionality of the affected region. However, the sensory and motor functions will never be returned to normal levels in these injuries.

Background: Cardiac injury is uncommon, but it is important to diagnose, in order to prevent subsequent complications. Extended focused assessment with sonography in trauma (eFAST) allows rapid evaluation of the pericardium and thorax. The objective of this study was to describe cardiac injuries presenting to a major trauma centre and the diagnostic performance of eFAST in detecting haemopericardium as well as broader cardiac injuries. Methods: Data of patients with severe injuries and diagnosed cardiac injuries (Injury Severity Score >12 and AIS 2008 codes for cardiac injuries) were extracted from The Alfred Trauma Registry over a four-year period from July 2010 to June 2014. The initial eFAST results were compared to those of the final diagnosis, which were determined after analysing imaging results and intraoperative findings. Results: Thirty patients who were identified with cardiac injuries met the inclusion criteria. Among these, 22 patients sustained injuries under the scope of eFAST, of which a positive eFAST scan in the pericardium was reported in 13 (59%) patients, while nine (41%) patients had a negative scan. This resulted in a sensitivity of 59% (95% CI: 36.7%–78.5%). The sensitivity of detecting any cardiac injuries was lower at 43.3% (95% CI: 26.0–62.3). Conclusions: The low sensitivities of eFAST for detecting cardiac injuries and haemopericardium demonstrate that a negative result cannot be used in isolation to exclude cardiac injuries. A high index of suspicion for cardiac injury remains essential. Adjunct diagnostic modalities are indicated for the diagnosis of cardiac injury following major trauma.

Background: Over 85% of chest injuries requiring surgical intervention can be managed with tube thoracostomy/intercostal catheter (ICC) insertion alone. However, complication rates of ICC insertion have been reported in the literature to be as high as 37%. Insertional complications, including the incorrect identification of the safe zone chest wall location for ICC placement, are common issues, with up to 41% of insertions occurring outside of this safe area. A new biometric approach using the patient's proportional skeletal upper limb anatomy to allow correct identification of the chest wall skin site for ICC insertion may reduce complications. Aim: The aim of this study was to examine the performance of the mid-arm point (MAP) method in identifying the safe zone for ICC insertion. Methods: Thirty healthy volunteers were recruited from The Alfred Hospital, a Level I Adult Trauma Centre in Melbourne, Australia. Blinded investigators used the MAP to measure the mid-point of the adducted arm of each volunteer bilaterally. A skin marking was placed on the anterior axillary line of the adjacent chest wall, and with the arm then abducted to 90 degrees, the underlying intercostal space was identified. Results: Using the MAP method, all of the 120 measurements fell within the ‘safe zone’ of the fourth to sixth intercostal spaces bilaterally. The median intercostal space identified was the fifth space, with investigators finding this in 86% of measurements independent of age, sex, height, weight or side. Conclusion: A simple technique using the MAP is a reliable marker for the identification of the safe zone for ICC insertion in healthy volunteers. The clinical utility for patients undergoing pleural decompression and drainage needs prospective evaluation.

Aim: The purpose of this study was to provide an overview of the evolution of emergency medical services (EMS) in Saudi Arabia to describe its history, organisational service providers, governance, EMS statistics and the educational development of the field with the disparity of educational approaches. Background: The EMS is an important part of the healthcare system as it is often the first point of contact for medical emergencies. The EMS in Saudi Arabia has seen a number of positive changes over the past decade, some of which include the development of several university and college programs dedicated to teaching EMS, the evaluation of the profession from a post-employment first aid model into a pre-employment bachelor's degree model, the generous governmental scholarship grants overseas and the official accreditation of EMS as a profession. It has been approximately nine years since the first EMS bachelor's degree programs were developed in Saudi Arabia, some of which were directly adopted from universities in developed countries such as Australia. Despite these positive changes, the current EMS system in Saudi is faced with many challenges, both organisational and educational, including the lack of research, community involvement, the educational status of practitioners and the inconsistencies of statistics relating to response time and rate of transfer. This paper describes the history of EMS in Saudi Arabia with a specific focus on identifying the disparity in the educational outcomes and approaches adopted by colleges and universities in the Kingdom. Methods: The data utilised for the research of the EMS profession in Saudi Arabia were obtained from the literature using search tools such as MEDLINE, Google Scholar, Saudi health journals, Saudi university websites, government reports and statistics. Conclusion: The EMS profession in Saudi Arabia has advanced greatly in the past 12 years. Yet there is still scope for considerable improvement, especially with regards to developing empirically identified core competencies for EMS bachelor's degree graduates. There is also the need for providing more outreach to the public to improve awareness of current services and available training, building more collaboration between the industry employers and academic institutions and investing further in EMS research through the development of Saudi-based postgraduate master's and PhD EMS degrees. This paper is the first to provide an overview of the EMS service in Saudi Arabia, for institutions and researchers to gain a better understanding of the history and current standing of the service from an educational and operational perspective.

Background: Prevention of secondary spinal injury via spinal protection measures is a standard component of trauma management, and a high-quality spinal clearance process is imperative in achieving this aim. To evaluate the current practice with a view to achieving best practice, we sought to examine the spinal clearance process and outcomes at a regional Australian referral hospital, which services a large geographical catchment area. Methods: A retrospective review of medical records of all patients with major trauma who presented to an Australian regional hospital during 2014 was conducted. The primary outcome measure was missed or delayed diagnosis of spinal injury. Secondary outcome measures included compliance with internationally accepted spinal clearance process measures, timing and choice of appropriate imaging modalities, rates of spinal injury and documentation of spinal clearance. Results: Of the 112 patients with major trauma who met the study eligibility criteria and were discharged from hospital during the study period from 1 January to 31 December 2014, 11 spinal injuries were missed or delayed in diagnosis. The injuries occurred in 3.6% of patients and all were thoracolumbar spine (TLS) injuries. The predominant reasons for missed or delayed diagnosis were reduced sensitivity of plain X-ray compared with computed tomography for spinal injury screening and incomplete full spinal imaging to detect non-contiguous fractures. Conclusion: Evidence-based clinical decision rules are imperative in ascertaining the need for imaging in the TLS and would be enhanced by an internationally recognised definition of clinical significance based on injury morphology rather than clinician management decision alone. In addition, regional hospitals may have limited capacity to achieve spinal clearance, and other trauma quality assurance standards commensurate with national and international benchmarks without the valuable performance feedback provided by state trauma registries, as is currently the case in Queensland.

Background: Healthcare costs associated with the diagnosis of benign paroxysmal positional vertigo (BPPV) alone approach $2 billion per year in the United States. Post-traumatic BPPV (t-BPPV) is well recognized, and can be managed with simple bedside physical maneuvers. Despite the availability of literature and clear guidelines supporting this approach, physical maneuvers are underutilized. The aim of this study was to explore the reasons for this practice disagreement. Methods: A cross-sectional survey of emergency physicians (EP) and non-emergency physicians (Non-EPs) managing head injury patients was conducted. The survey questions were aimed to explore the attitude of these frontline healthcare providers towards the diagnosis and management of t-BPPV in head injury patients. Results: A total of 102 physicians completed the survey. Of them, male physicians constituted 87.2%, and the majority were working as emergency physicians (80.4%). Although nearly three-fourths (72.5%; n = 74) of the participants admitted that it is important to explore the possibility of t-BPPV in patients with head injury, only one-fifth of the participating physicians (20.6%; 21 of 102) confirmed that they would investigate for t-BPPV. A lack of knowledge about t-BPPV in more than half of the study participants (55.9%; n = 57) was the main reason for them not probing the possibility of t-BPPV. Conclusion: To close the gap between available evidence-based guidelines and actual clinical practice, there is a need for raising awareness about this condition. Addressing the training needs of frontline healthcare providers to use physical maneuvers such as Dix–Hallpike (DHM) and canalith repositioning (CRP) maneuvers in the management of t-BPPV is an important step that needs to be taken.

Objectives: Standard emergency department (ED) operation goals include minimization of the time interval between patients' initial ED presentation and initial emergency physician (EP) evaluation. Following up on previous work defining factors influencing the “time to physician” (tMD) in a busy ED, the current study was undertaken to evaluate whether tMD was adversely impacted by the ED's partial replacement of specialist-grade EPs with emergency medicine (EM) trainees (at the resident and fellow level). Methods: This retrospective study was conducted for four months (September–December 2015) using an ED administrative database (EDAD) in an urban academic tertiary ED with an annual census of approximately 500,000; during the four study months, the ED census was 165,969. To minimize confounding by time of day and related factors, data analysis focused solely on the “day shift” (0600–1400) of each of the study period's 122 days. EDAD data were combined with EP rostering data to generate a multivariate linear regression model that assessed the dependent variable tMD, for significant changes associated with increasing proportion – not necessarily always the same as increasing the absolute number of trainees (i.e., summed residents and fellows as a total percent of all on-duty EPs). There were trainees in the study ED throughout the study, but the trainee numbers as a proportion of the overall physician staffing fluctuated, thus providing a basis for analysis. The model adjusted for covariates previously demonstrated to impact tMD at the study center. Analyses were conducted with Stata 14MP, with statistical significance defined at p < 0.05 and confidence intervals (CIs) reported at the 95% level. Results: In an acceptable regression model that adjusted for multiple parameters influencing tMD, the introduction of a covariate representing the proportion of on-duty trainee physicians was very small in magnitude (β estimate 0.07, 95% CI − 0.16 to 0.30) and not statistically significant (p = 0.53). Conclusions: A multivariate analysis adjusting for variables contributing to tMD showed no indication of adverse tMD impact from partial replacement of board-certified specialist-grade EPs with EM trainees given adequate supervision by properly trained faculty.

Background: Helicopter emergency medical services (HEMS) and ground EMS (GEMS) are both integral parts of out-of-hospital transport systems for patients with ST-elevation myocardial infarction (STEMI) undergoing emergency transport for primary percutaneous coronary intervention (PPCI). There are firm data linking time savings for PPCI transports with improved outcome. A previous pilot analysis generated preliminary estimates for potential HEMS-associated time savings for PPCI transports. Methods: This non-interventional multicenter study conducted over the period 2012–2014 at six centers in the USA and in the State of Qatar assessed a consecutive series of HEMS transports for PPCI; at one center consecutive GEMS transports of at least 15 miles were also assessed if they came from sites that also used HEMS (dual-mode referring hospitals). The study assessed time from ground or air EMS dispatch to transport a patient to a cardiac center, through to the time of patient arrival at the receiving cardiac unit, to determine proportions of patients arriving within accepted 90- and 120-minute time windows for PPCI. Actual times were compared to “route-mapping” GEMS times generated using geographical information software. HEMS' potential time savings were calculated using program-specific aircraft characteristics, and the potential time savings for HEMS was translated into estimated mortality benefit. Results: The study included 257 HEMS and 27 GEMS cases. HEMS cases had a high rate of overall transport time (from dispatch to receiving cardiac unit arrival) that fell within the predefined windows of 90 minutes (67.7% of HEMS cases) and 120 minutes (91.1% of HEMS cases). As compared to the calculated GEMS times, HEMS was estimated to accrue a median time saving of 32 minutes (interquartile range, 17–46). The number needed to transport for HEMS to get one additional case to PPCI within 90 minutes was 3. In the varied contexts of this multicenter study, the number of lives saved by HEMS, solely through time savings, was calculated as 1.34 per 100 HEMS PPCI transports. Conclusions: In this multicenter study, HEMS PPCI transport was found to be appropriate as defined by meeting predefined time windows. The overall estimate for lives saved through time savings alone was consistent with previous pilot data and was also generally consistent with favorable cost-effectiveness. Further research is necessary to confirm these findings, but judicious HEMS deployment for PPCI transports is justified by these data.
