      https://bmjopen.bmj.com/content/bmjopen/8/9/e022464.full.pdf Objectives The aim of this study is to describe the demographics of reported traumatic cardiac arrest (TCA) victims, prehospital resuscitation and survival to hospital rate. Setting Helicopter Emergency Medical Service (HEMS) in south-east England, covering a resident population of 4.5million and a transient population of up to 8million people. Participants Patients reported on the initial 999 call to be in suspected traumatic cardiac arrest between 1 July 2016 and 31 December 2016 within the trust’s geographical region were identified. The inclusion criteria were all cases of reported TCA on receipt of the initial emergency call. Patients were subsequently excluded if a medical cause of cardiac arrest was suspected. Outcome measures Patient records were analysed for actual presence of cardiac arrest, prehospital resuscitation procedures undertaken and for survival to hospital rates. Results 112 patients were reported to be in TCA on receipt of the 999/112 call. 51 (46%) were found not to be in TCA on arrival of emergency medical services. Of the ‘not in TCA cohort’, 34 (67%) received at least one advanced prehospital medical intervention (defined as emergency anaesthesia, thoracostomy, blood product transfusion or resuscitative thoracotomy). Of the 61 patients in actual TCA, 10 (16%) achieved return-ofspontaneous circulation. In 45 (88%) patients, the HEMS team escorted the patient to hospital. Conclusion A significant proportion of patients reported to be in TCA on receipt of the emergency call are not in actual cardiac arrest but are critically unwell requiring advanced prehospital medical intervention. Early activation of an enhanced care team to a reported TCA call allows appropriate advanced resuscitation. Further research is warranted to determine which interventions contribute to improved TCA survival. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6129099/pdf/bmjopen-2018-022464.pdf This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.

    • Temporal and geographic patterns of stab injuries in young people: a retrospective cohort study from a UK major trauma centre

      https://bmjopen.bmj.com/content/8/10/e023114.long Objectives To describe the epidemiology of assaults resulting in stab injuries among young people. We hypothesised that there are specific patterns and risk factors for injury in different age groups. Design Eleven-year retrospective cohort study. Setting Urban major trauma centre in the UK. Participants 1824 patients under the age of 25 years presenting to hospital after a stab injury resulting from assault. Outcomes Incident timings and locations were obtained from ambulance service records and triangulated with prospectively collected demographic and injury characteristics recorded in our hospital trauma registry. We used geospatial mapping of individual incidents to investigate the relationships between demographic characteristics and incident timing and location. Results The majority of stabbings occurred in males from deprived communities, with a sharp increase in incidence between the ages of 14 and 18 years. With increasing age, injuries occurred progressively later in the day (r2 =0.66, p<0.01) and were less frequent within 5 km of home (r2 =0.59, p<0.01). Among children (age <16), a significant peak in injuries occurred between 16:00 and 18:00 hours, accounting for 22% (38/172) of injuries in this group compared with 11% (182/1652) of injuries in young adults. In children, stabbings occurred earlier on school days (hours from 08:00: 11.1 vs non-school day 13.7, p<0.01) and a greater proportion were within 5 km of home (90% vs non-school day 74%, p=0.02). Mapping individual incidents demonstrated that the spike in frequency in the late afternoon and early evening was attributable to incidents occurring on school days and close to home. Conclusions Age, gender and deprivation status are potent influences on the risk of violent injury in young people. Stab injuries occur in characteristic temporal and geographical patterns according to age group, with the immediate after-school period associated with a spike in incident frequency in children. This represents an opportunity for targeted prevention strategies in this population. https://bmjopen.bmj.com/content/bmjopen/8/10/e023114.full.pdf This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.

    • What is the most appropriate out-of-hospital opioid for adults with traumatic pain?

      Ellis, Pierre (2017-12-06)
      Methods: The literature search was carried out using multiple databases to identify relevant out-of-hospital research with additional grey literature to support. The main themes encountered were intravenous morphine compared to intravenous fentanyl, and the contrast between them. Discussion: There were no significant differences in effectiveness or adverse effects. Intranasal application was thought to be favoured where intravenous access was unobtainable. Conclusions: Further research is required to establish which is the most appropriate opioid. This could include a greater focus on the onset time, duration and optimal dose. Increased education and organisational focus would need to be addressed alongside a change in drug formulary for the out-of-hospital clinician. Abstract published with permission.
