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

ABSTRACT:

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.

Project description:BackgroundGuidance for the management of thermal injuries has evolved with improved understanding of burn pathophysiology. Guidance for the management of cold burn injuries is not widely available. The management of these burns differs from the standard management of thermal injuries. This study aimed to review the etiology and management of all cold burns presenting to a large regional burn centre in the UK and to provide a simplified management pathway for cold burns.MethodsAn 11-year retrospective analysis (1 January 2003-31 December 2014) of all cold injuries presenting to a regional burns centre in the UK was conducted. Patient case notes were reviewed for injury mechanism, first aid administered, treatment outcomes and time to healing. An anonymized nationwide survey on aspects of management of cold burns was disseminated between 13 July 2015-5 October 2015 to British Association of Plastic Reconstructive and Aesthetic Surgeons (BAPRAS) and Plastic Surgery Trainees Association (PLASTA) members in the UK. Electronic searches of MEDLINE, EMBASE and the Cochrane Library were performed to identify relevant literature to provide evidence for a management pathway for cold burn injuries.ResultsTwenty-three patients were identified. Age range was 8 months-69 years. Total body surface area (TBSA) burn ranged from 0.25 to 5 %. Twenty cases involved peripheral limbs. Seventeen (73.9 %)cases were accidental, with the remaining six (26.1 %) cases being deliberate self-inflicted injuries. Only eight patients received first aid. All except one patient were managed conservatively. One case required skin graft application due to delayed healing. We received 52 responses from a total of 200 questionaires. Ninety percent of responders think clearer guidelines should exist. We present a simplified management pathway based on evidence identified in our literature search.ConclusionsCold burns are uncommon in comparison to other types of burn injuries. In the UK, a disproportionate number of cold burn injuries are deliberately self-inflicted, especially in the younger patient population. Our findings reflect a gap in clinical knowledge and experience. We proposed a simplified management pathway for managing cold burn injuries, consisting of adequate first aid using warm water, oral prostaglandin inhibitors, deroofing of blisters and topical antithromboxane therapy.

Project description:BACKGROUND:There is increasing interest in the timely administration of concentrated sources of fibrinogen to patients with major traumatic bleeding. Following evaluation of early cryoprecipitate in the CRYOSTAT 1 trial, we explored the use of fibrinogen concentrate, which may have advantages of more rapid administration in acute haemorrhage. The aims of this pragmatic study were to assess the feasibility of fibrinogen concentrate administration within 45 minutes of hospital admission and to quantify efficacy in maintaining fibrinogen levels ??2 g/L during active haemorrhage. METHODS:We conducted a blinded, randomised, placebo-controlled trial at five UK major trauma centres with adult trauma patients with active bleeding who required activation of the major haemorrhage protocol. Participants were randomised to standard major haemorrhage therapy plus 6 g of fibrinogen concentrate or placebo. RESULTS:Twenty-seven of 39 participants (69%; 95% CI, 52-83%) across both arms received the study intervention within 45 minutes of admission. There was some evidence of a difference in the proportion of participants with fibrinogen levels ??2 g/L between arms (p?=?0.10). Fibrinogen levels in the fibrinogen concentrate (FgC) arm rose by a mean of 0.9 g/L (SD, 0.5) compared with a reduction of 0.2 g/L (SD, 0.5) in the placebo arm and were significantly higher in the FgC arm (p?<?0.0001) at 2 hours. Fibrinogen levels were not different at day 7. Transfusion use and thromboembolic events were similar between arms. All-cause mortality at 28 days was 35.5% (95% CI, 23.8-50.8%) overall, with no difference between arms. CONCLUSIONS:In this trial, early delivery of fibrinogen concentrate within 45 minutes of admission was not feasible. Although evidence points to a key role for fibrinogen in the treatment of major bleeding, researchers need to recognise the challenges of timely delivery in the emergency setting. Future studies must explore barriers to rapid fibrinogen therapy, focusing on methods to reduce time to randomisation, using 'off-the-shelf' fibrinogen therapies (such as extended shelf-life cryoprecipitate held in the emergency department or fibrinogen concentrates with very rapid reconstitution times) and limiting the need for coagulation test-based transfusion triggers.

Project description:Background:Nasal fractures present in 39% of patients with facial trauma. These patients are assessed in the emergency department followed by outpatient review in the senior house officer-led emergency ear, nose and throat (ENT) clinic. Inadequate treatment of nasal trauma can result in debilitating functional and aesthetic problems. Inexperienced junior doctors may be apprehensive in assessing nasal trauma resulting in time pressured clinics and suboptimal management. Measures:A retrospective review of clinical noting over 3 months was carried out to gauge the extent of the problem. Three baseline measurements for satisfactory quality of assessments included: (1) 3/5 key symptoms elicited by the clinician (epistaxis, rhinorrhoea, nasal airway obstruction, dental malocclusion and diplopia). (2) Presence/absence of 'septal haematoma' (SH) and 'deviated nasal septum' (DNS) documented. (3) Patient follow-up within 2 weeks after the initial injury. Three Plan-Do-Study-Act (PDSA) cycles were conducted with implementation of interventions (proforma, clinic poster, patient information leaflet and training) as visualised in our 'driver diagram'. Results:The quality of nasal trauma assessments improved following each intervention. There was an increase from 86% to 100% patients being seen within 2 weeks of the injury. There was an improvement in quality of assessments following the teaching as two-thirds (PDSA cycle 2) followed by 100% (PDSA cycle 3) of clinical documentation included 'rhinorrhoea' and 83% (PDSA cycle 2) to 100% (PDSA cycle 3) included 'nasal airway obstruction'. Similarly, two thirds (PDSA cycle 2) followed by 100% (PDSA cycle 3) examined and documented the presence/absence of SH and DNS. A 100% improvement in trainee confidence was reported. We are now conducting more comprehensive assessments of nasal trauma patients. Conclusion:The need to provide relevant training and support to ENT junior doctors is crucial in their development, as well as to ensure delivery of high-quality patient-centred care.

Project description:BackgroundStudies from countries such as Australia and South Africa have demonstrated a difference in the types of injury managed in rural hospitals compared to larger, urban hospitals and so conclude staff require a different skill-set to work in these environments. There is some evidence this attitude may be prevalent amongst UK surgical trainees, resulting in difficulty recruiting to rural settings. In addition, studies have compared mortality in paediatric trauma patients in rural and urban hospitals, but none have described types of injury or orthopaedic operations required.We hypothesise the distribution of operative, orthopaedic paediatric trauma in a rural district general and an urban major trauma centre will not differ significantly in terms of patterns and mechanism of injury, orthopaedic intervention or time to theatre.Materials/methodsAll operative paediatric patients (0-15yrs) seen during an acute orthopaedic take at a rural district general and an urban major trauma centre were included. Non-operative admissions were excluded. Patients were identified using daily trauma work lists from each site. Outcomes were age, injury type, operation, time to theatre, seasonality and mechanism.Results183 patients from the urban hospital and 103 from the rural were identified. There were no significant differences found in age of patient, seasonality or time to theatre between cohorts (p > 0.05). There were also broadly similar patterns of injury and operations performed in both groups, although k-wiring was more often employed in the rural cohort than the urban (27% vs 17% of total operations). There were more bicycle and shinty related injuries in the rural cohort, and equine related in the urban.ConclusionsPaediatric trauma admissions do not vary significantly between rural and urban trauma centres, although the types of procedure performed may be less conservative in a rural hospital. This may be due to geography or differences in ED practice.
