BackgroundIncreasing age and significant pre-existing medical conditions (PMCs) are independent risk factors associated with increased mortality after trauma. Our aim was to review all trauma deaths, identifying the cause and the relation to time from injury, ISS, age and PMCs.MethodsA retrospective analysis of trauma deaths over a 6-year period at the study centre was conducted. Information was obtained from the Trauma Audit and Research Network (TARN) dataset, hospital records, death certificates and post-mortem reports. The time and cause of death, ISS, PMCs were analysed for two age groups (<65 years and ≥ 65 years).ResultsPatients ≥ 65 years old were at an increased risk of death (OR 6.4, 95% CI 5.2-7.8, p < 0.001). Thirty-two patients with an ISS of >15 and died within the first 24 hours of admission, irrespective of age, from causes directly related to their injuries. Twelve patients with an ISS of <16, died after 13 days of medical conditions not directly related to their injuries (p = 0.01). Thirty four patients had significant PMCs, of which 11 were <65 years (34.4% of that age group) and 23 were ≥ 65 years (95.8% of that age group) (p = 0.02). The risk of dying late after sustaining minor trauma (ISS <16) is increased if a PMC exists (OR 5.5, p = 0.004).ConclusionElderly patients with minor injuries and PMCs have an increased risk of death relative to their younger counterparts and are more likely to die of medical complications late in their hospital admission.

England SUMMARYThe value of prophylactic antibiotics in7iie -treatment of animal bites is uncertain. A prospective double blind stratified trial was performed comparing a broad spectrum antibiotic amoxycillin/clavulanate with placebo in full thickness animal bite wounds in a series of 185 consecutive patients.In wounds less than 9 h old, no significant benefit was found with the antibiotic. In older wounds, presenting 9-24 h after injury, the infection rate was reduced significantly (P= 0-023), although the numbers were small. We recommend the use of such an antibiotic on wounds 9-24 h old and query its use in more recent injuries, unless tendons or joints are likely to be involved.

We describe the use of a specialist referral clinic and ultrasound assessment for all injuries to the ulnar collateral ligament of the metacarpophalangeal joint of the thumb presenting to an Accident and Emergency (A&E) department. Senior House Officers in the A&E department were able to correctly diagnose only 45% of the ruptures of the ulnar collateral ligament. The overall agreement between specialist clinic examination and ultrasound for injury to the ulnar collateral ligament was 85% (kappa 0.647). When compared with the operative finding ultrasound had a positive predictive value for rupture of 94%. An algorithm is presented for the assessment of injuries to the ulnar collateral ligament in A&E departments.
