The Open-Fracture Patient Evaluation Nationwide (OPEN) study : epidemiology of open fracture care in the UK

AIMS

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

METHODS

Any patient admitted to hospital with an open fracture between 1 June 2021 and 30 September 2021 was included, excluding phalanges and isolated hand injuries. Institutional information governance approval was obtained at the lead site and all data entered using Research Electronic Data Capture. Demographic details, injury, fracture classification, and patient dispersal were detailed.

RESULTS

In total, 1,175 patients (median age 47 years (interquartile range (IQR) 29 to 65), 61.0% male (n = 717)) were admitted across 51 sites. A total of 546 patients (47.1%) were employed, 5.4% (n = 63) were diabetic, and 28.8% (n = 335) were smokers. In total, 29.0% of patients (n = 341) had more than one injury and 4.8% (n = 56) had two or more open fractures, while 51.3% of fractures (n = 637) occurred in the lower leg. Fractures sustained in vehicle incidents and collisions are common (38.8%; n = 455) and typically seen in younger patients. A simple fall (35.0%; n = 410) is common in older people. Overall, 69.8% (n = 786) of patients were admitted directly to an orthoplastic centre, 23.0% (n = 259) were transferred to an orthoplastic centre after initial management elsewhere, and 7.2% were managed outwith specialist units (n = 81).

CONCLUSION

This study describes the epidemiology of open fractures in the UK. For a decade, orthopaedic surgeons have been practicing in a guideline-driven, network system without understanding the patient features, injury characteristics, or dispersal processes of the wider population. This work will inform care pathways as the UK looks to the future of trauma networks and guidelines, and how to optimize care for patients with open fractures.Cite this article: Bone Jt Open 2022;3(10):746-752.

The association of hand and wrist injuries with other injuries in multiple trauma patients. A retrospective study in a UK Major Trauma Centre

BACKGROUND

Approximately 20,000 major trauma cases occur in England every year. However, the association with concomitant upper limb injuries is unknown. This study aims to determine the incidence, injury pattern and association of hand and wrist injuries with other body injuries and the Injury Severity Score (ISS) in multiply injured trauma patients.

METHODS

Single centre retrospective study was performed at a level-one UK Major Trauma Centre (MTC). Trauma Audit and Research Network (TARN) eligible multiply injured trauma patients that were admitted to the hospital between January 2014 and December 2018 were analysed. TARN is the national trauma registry. Eligible patients were: a trauma patient of any age who was admitted for 72 h or more, or was admitted to intensive care, or died at the hospital, was transferred into the hospital for specialist care, was transferred to another hospital for specialist care or for an intensive care bed and whose isolated injuries met a set of criteria. Data extracted included: age, gender, mode of arrival, location of injuries including: hand and/or wrist and mechanism of injury. We performed a logistic regression analysis to assess the association between hand/wrist injury to ISS score of 15 points or above/below and to the presentation of other injuries.

RESULTS

107 patients were analysed. Hand and wrist injuries were the second most common injury (26.2%), after thoracic injuries. Distal radial injuries were found in 5.6%, carpal/carpometacarpal in 6.5%, concurrent distal radius and carpometacarpal in 0.9%, phalangeal injuries in 4.7%, tendon injuries in 0.9% and concurrent hand and wrist injuries in 7.5% cases. There was a significant association between hand or wrist injuries and lower limb injuries (Odds Ratio (OR): 3.84; 95% confidence intervals (CI): 1.09 to 13.50; p = 0.04) and pelvic injuries (OR: 4.78; 95% CI: 1.31 to 17.44; p = 0.02). There was no statistical association between hand and wrist injuries and ISS score (OR: 0.80; 95% CI: 0.11 to 5.79; p = 0.82).

CONCLUSIONS

Hand and wrist injuries are prevalent in trauma patients admitted to MTCs. They should not be under-estimated but routinely screened for in multiply injured patients particularly those with a pelvic or lower limb injury.

Pelvic and acetabular fracture care in England: current workload and future directions

INTRODUCTION

Fractures of the pelvis and acetabulum (PAFs) are challenging injuries, requiring specialist surgical input. Since implementation of the major trauma network in England in 2012, little has been published regarding the available services, workforce organisation and burden of PAF workload. The aim of this study was to assess the recent trends in volume of PAF workload, evaluate the provision of specialist care, and identify variation in available resources, staffing and training opportunity.

METHODS

Data on PAF volume, operative caseload, route of admission and time to surgery were requested from the Trauma Audit and Research Network. In order to evaluate current workforce provision and services, an online survey was distributed to individuals known to provide PAF care at each of the 22 major trauma centres (MTCs).

RESULTS

From 2013 to 2019, 23,823 patients with PAF were admitted to MTCs in England, of whom 12,480 (52%) underwent operative intervention. On average, there are 3,971 MTC PAF admissions and 2,080 operative fixations each year. There has been an increase in admissions and cases treated operatively since 2013. Three-quarters (78%) of patients present directly to the MTC while 22% are referred from regional trauma units. Annually, there are on average 37 operatively managed PAF injuries per million population. Notwithstanding regional differences in case volume, the average number of annual PAF operative cases per surgeon in England is 30. There is significant variation in frequency of surgeon availability. There is also variation in rota organisation regarding consistent specialist surgeon availability.

CONCLUSIONS

This article describes the provision of PAF services since the reorganisation of trauma services in England. Future service development should take into account the current distribution of activity, future trends for increased volume and casemix, and the need for a PAF registry.

Pelvic fractures: experience of pelvic ring fractures at a major trauma centre

In this review, we discuss the imaging classification of pelvic ring fractures in the context of our experience of reporting trauma computed tomography (CT) in a major trauma centre. Pelvic ring fractures are potentially significant injuries with risk of significant haemorrhage and morbidity. This review details the use of classification systems in determining the mechanism and severity of injury, with discussion of the features of the Young and Burgess classification system. We demonstrate the different types of pelvic ring fracture with examples from trauma CT, and with reference to the distribution and frequency of these injuries in trauma patients. This review will allow the reader to assess trauma CT for significant pelvic ring injury and identify features of instability.
