Quad bike related trauma in Ireland.

INTRODUCTION: A quad bike or an all-terrain vehicle is a four-wheeled powered vehicle generally designed for off-road use. They are widely used for farm-related work and more recently for recreational purposes. The potential for serious injury and death with quad bike use is a growing public health concern. There is an inherent instability in their design and they are typically used on rugged terrain characterised by dangerous driving surfaces. This study examines quad bike related trauma in Ireland using a national trauma registry to identify patient demographics, injury mechanism and type, treatments received and outcomes. METHODS: All quad bike related trauma cases recorded on the Major Trauma Audit (MTA), National Office of Clinical Audit in Ireland for the period 2014-2019 were gathered and analysed. RESULTS: There were 69 cases identified and 63 (91 %) of these were male. The median (IQR) age was 27 (19 - 49.1). There were 25 % (n = 17) aged 0-18 years, 64 % (n = 44) aged 19-65 and 12 % (n = 8) aged greater than 65 years. The median injury severity score (ISS) was 10 (IQR 9-22). The most severely injured body region was the head (n = 21, 30 %). No helmet use was recorded in 50 % (n = 34) of cases. October recorded the highest number of cases (n = 9, 13 %), and Sunday was the most common day (n = 17, 25 %). The median length of hospital stay was five days (IQR 3-9). One patient died after arrival to hospital. CONCLUSION: Quad bike related trauma predominantly affects a young male cohort with serious injury characteristics. A sizeable proportion of patients are under 18 years of age. This data can better inform national policies and public awareness campaigns targeting this trauma subset. The head was the most common severely injured body region, highlighting the potential need for legislative intervention regarding mandatory helmet use. A large cohort of patients required transfer for definitive care which has implications for trauma care pathways and advocates for the development of an integrated trauma system in Ireland.

Is the increased use of intramedullary nailing over DHS for intertrochanteric hip fractures justified? - A review of the Irish hip fracture database 2016 -2020.

PURPOSE: Intertrochanteric hip fractures are significant and costly injuries and there remains controversy within the orthopaedic literature over the best method of fixation. The Irish Hip Fracture Database (IHFD) was established in 2012 to drive improvements in clinical outcomes and the quality of hip fracture care. This paper will review the outcomes of dynamic hip screw (DHS) versus intra-medullary nailing (IMN) in the treatment of intertrochanteric hip fractures in Ireland. METHODS: Eligible cases for this study include patients >60 years of age with trochanteric hip fractures treated by DHS or IMN between January 2016 and December 2020. Outcomes recorded and compared include length of stay, inpatient mortality, mobilisation on post-operative day 1 (POD 1), and discharge destination. RESULTS: 5668 hip fractures treated with DHS or IMN were identified. There was no significant difference between inpatient mortality, re-operation rate or length of stay between the two groups. Females and patients with a high ASA grade (IV and V) were more likely to receive IMN. Patients receiving DHS were more likely to be mobilised day 1 post-operatively and be discharged directly home. It was noted that the use of IMN increased from 42% of cases in 2016 to 70% in 2020. CONCLUSION: IMN use for intertrochanteric fractures continues to increase. However, patients treated with DHS were more likely to mobilise early post-operatively and to go directly home. Notwithstanding the limitations of national registry data research, the dramatic rise in the use of IMN for these fractures appears unsupported by the evidence.

Intracapsular hip fractures: A comparative study of cemented and uncemented hemiarthroplasties in the Irish hip fracture database.

BACKGROUND: The aim of this study was to analyse the association between use of cement for stem fixation in hip hemiarthroplasty and the outcomes of mobility, mortality, and discharge destination. METHODS: The Irish Hip Fracture Database was examined from 2016 to 2020 to assess for any difference in post op mobility, 7-day, 14-day and inpatient mortality, and discharge destination. RESULTS: A total of 7109 hemi-arthroplasties were identified from 2016 to 2020. 71.6 % were cemented (n = 5,172), with 28.4 % uncemented (1,937). There was no difference in day 1 post op mobilisation (79.7 % vs 80.9 %) or cumulative ambulatory score on discharge (2.5 vs 2.4). The mortality rate was equivocal at all time points between the cemented and uncemented groups (7 day (.9 % vs 1.2 %), 14 day (1.9 % vs 2.3 %), inpatient (4 % vs 5.1 %)). There was no difference in length of stay (11 vs 12 days) or discharge to home directly (21 % vs 27 %). CONCLUSION: The use of cement did not have any significant difference on post op mortality, mobility or discharge destination.

Patient and hospital-level factors associated with time to surgery after hip fracture in Ireland: Analysis of national audit data 2016-2020.

INTRODUCTION: In hip fracture care, time to surgery (TTS) is a commonly used quality indicator associated with patient outcomes including mortality. This study aimed to identify patient and hospital-level characteristics associated with TTS in Ireland. METHODS: National data from the Irish Hip Fracture Database (IHFD) (2016-2020) were analysed along with hospital-level characteristics obtained from a 2020 organisational survey. Generalised linear model regression was used to explore the association of TTS with case-mix, surgical details, hospital-level staffing and specific protocols recommended to expedite surgery. RESULTS: A total of 14,951 patients with surgically treated hip fracture from 16 hospitals were included (Mean age= 80.6 years (SD=8.8), 70.4% female). Mean TTS was 40.9 h (SD=60.3 h). Case-mix factors associated with longer TTS were male sex and higher American Society of Anaesthesiologists (ASA) grade. Other factors found to be associated with longer TTS included low pre-morbid mobility, inter-hospital transfer, weekday presentation, pre-operative medical physician assessment, intracapsular fracture type, arthroplasty surgery, general anaesthesia, consultant grade of surgeon and lower hospital-level orthopaedic surgical capacity. The oldest age-group and pre-fracture nursing home residence were associated with shorter TTS when adjusted for other case-mix factors. None of four explored protocols for expediting surgery were associated with TTS. CONCLUSION: Patients with more comorbidity experience longer surgical delay after hip fracture in Ireland, in line with international research. Low availability of senior orthopaedic surgeons in Ireland may be delaying hip fracture surgery. Pathway of presentation, including via inter-hospital transfer or hospital bypass, is an important factor that requires further exploration. Further research is required to identify successful system-level protocols and interventions that may expedite hip fracture surgery within this setting.

Long-term outcome collection after hip fracture in Ireland: a systematic review of traditional and grey literature.

This review aimed to describe the methods and results from recent Irish research about post-acute hip fracture outcomes. Meta-analyses estimate the 30-day and 1-year mortality rate at 5% and 24% respectively. There is a need for standardised recommendations about which data should be recorded to aid national and international comparisons. PURPOSE: Over 3700 older adults experience hip fracture in Ireland annually. The Irish Hip Fracture Database national audit records acute hospital data but lacks longer-term outcomes. This systematic review aimed to summarise and appraise recent Irish studies that collected long-term hip fracture outcomes and to generate pooled estimates where appropriate. METHODS: Electronic databases and grey literature were searched in April 2022 for articles, abstracts, and theses published from 2005 to 2022. Eligible studies were appraised by two authors and outcome collection details summarised. Meta-analyses of studies with common outcomes were conducted where the sample was generalisable to the broad hip fracture population. RESULTS: In total, 84 studies were identified from 20 clinical sites. Outcomes commonly recorded were mortality (n = 48 studies; 57%), function (n = 24; 29%), residence (n = 20; 24%), bone-related outcomes (n = 20; 24%), and mobility (n = 17; 20%). One year post-fracture was the most frequent time point, and patient telephone contact was the most common collection method used. Most studies did not report follow-up rates. Two meta-analyses were performed. The pooled estimate for one-year mortality was 24.2% (95% CI = 19.1-29.8%, I2 = 93.8%, n = 12 studies, n = 4220 patients), and for 30-day mortality was 4.7% (95% CI = 3.6-5.9%, I2 = 31.3%, n = 7 studies, n = 2092 patients). Reports of non-mortality outcomes were deemed inappropriate for meta-analysis. CONCLUSION: Hip fracture long-term outcomes collected in Irish research are broadly in line with international recommendations. Heterogeneity of measures and poor reporting of methods and findings limits collation of results. Recommendations for standard outcome definitions nationally are warranted. Further research should explore the feasibility of recording long-term outcomes during routine hip fracture care in Ireland to enhance national audit.

Development of a Frailty Index in the Irish Hip Fracture Database.

INTRODUCTION: In older people, hip fracture can lead to adverse outcomes. Frailty, capturing biological age and vulnerability to stressors, can indicate those at higher risk. We derived a frailty index (FI) in the Irish Hip Fracture Database (IHFD) and explored associations with prolonged length of hospital stay (LOS ≥ 30 days), delirium, inpatient mortality and new nursing home admission. We assessed whether the FI predicted those outcomes independently of age, sex and pre-operative American Society of Anaesthesiology (ASA) score. MATERIALS AND METHODS: A 21-item FI was constructed with 17 dichotomous co-morbidities, three 4-level ordinal pre-morbid functional variables (difficulty with indoor mobility, outdoor mobility, and shopping) and nursing home provenance (yes/no). The FI was computed as the proportion of items present and divided into tertiles (low, medium, high risk). Independent associations between FI and outcomes were explored with logistic regression, from which we extracted adjusted Odds Ratios (aOR) and Areas Under the Curve (AUC). RESULTS: From 2017 to 2020, the IHFD included 14,615 hip fracture admissions, mean (SD) age 80.4 (8.8), 68.9% women. Complete FI data were available for 12,502 (85.5%). By FI tertile (low to high risk), prolonged LOS proportions were 5.9%, 16.1% and 23.1%; delirium 5.5%, 13.5% and 17.6%; inpatient mortality 0.6%, 3.3% and 10.1%; and new nursing home admission 2.2%, 5.9% and 11.3%. All associations were statistically significant (p < 0.001) independently of age and sex. AUC analyses showed that the FI score, added to age, sex, and ASA score, significantly improved the prediction of delirium and new nursing home admission (p < 0.05), and especially prolonged LOS and inpatient mortality (p < 0.001). CONCLUSIONS: A 21-item FI in the IHFD was a significant predictor of outcomes and added value to traditional risk markers. The utility of a routinely derived FI to more effectively direct limited orthogeriatric resources requires prospective investigation.

Increasing hip fracture volume following repeated lockdowns: an Irish multicentre study of periods pre-Covid, during Covid lockdown and following vaccination.

BACKGROUND: Older age groups were identified as a high-risk cohort for Covid-19 and thus were a focus of lockdown measures enacted internationally. Resultant decreased social mobility and physical activity levels are associated with sarcopenia, which may lead to increased risk of hip fracture upon resuming social integration and physical activities after easing of lockdown restrictions. AIMS: Our aim was to compare the incidence of hip fractures during the period following vaccination with subsequent relaxation of restrictions, to those prior to and during the Covid pandemic. METHODS: A multicentre retrospective cohort study was performed consisting of all patients presenting with a "hip" fracture to 3 regional trauma units over the relevant time periods in 2019, 2020 and 2021. Tallaght, Galway and Waterford University Hospitals are large academic teaching hospitals with a combined mixed urban and rural catchment of over 1 million people. FINDINGS: Four-hundred-fourteen patients in total were included in the final analysis, with 133 eligible hip fractures observed proceeding to operative treatment across the study period in 2019, 132 in 2020 and 149 in 2021, representing a 12.88% increase. Demographic data revealed similar patient cohorts with respect to age and gender, fracture pattern and treatment. CONCLUSIONS: An increase in hip fracture volume was observed during the period post vaccination with subsequent relaxation of restrictions and increased social mobility, compared to those prior to and during the Covid pandemic. These findings have implications for hospital planning and orthopaedic resourcing as we navigate our way forward past the Covid-19 Pandemic.

A retrospective review of patients who sustained traumatic brain injury in Ireland 2014-2019.

INTRODUCTION: Traumatic brain injury (TBI) is the most significant cause of death and disability resulting from major trauma. The aim of this study is to describe the demographics of TBI patients, the current pathways of care and outcomes in the Republic of Ireland from 2014 to 2019. METHODS: We performed a retrospective review of all TBI patients meeting inclusion criteria in Ireland's Major Trauma Audit (MTA) from 2014 to 2019. Severe TBI was defined as an abbreviated injury scale (AIS) ≥3 and GCS ≤8. RESULTS: During the study period, 30,891 patients sustained major trauma meeting inclusion criteria for MTA, of which 7,393 (23.9%) patients met the inclusion criteria for TBI; 1,025 (13.9%) were classified as severe. The median age was 60.6 years (IQR 36.9-78.0), 54.3 years (32.8-73.4) for males and 71.7 years (50.0-83.0) for females (p<0.001). Of patients with severe TBI, 185 (18.0%) were brought direct to a neurosurgical centre, 389 (37.9%) were transferred to a neurosurgical centre and 321 (31.3%) had a neurosurgical intervention performed. In patients sustaining severe TBI, older patients (Adjusted OR, 0.96,95% CI 0.95-0.97) and patients requiring another surgery (OR 0.31, 95%CI 0.18-0.53) were less likely to be secondarily transferred to a neurosurgical centre. There were 47 (4.6%) patients with severe TBI discharged to rehabilitation. The 30-day mortality in Ireland was 11.6% in all TBI patients and 45.5% in severe TBI patients. Older patients and patients with higher ISS had a higher chance of death. Male patients, patients treated in neurosurgical centre, patients who had neurosurgery or non-neurosurgical surgery had a higher chance of survival. CONCLUSION: This population-based study bench marks the 'as is' for patients with TBI in Ireland. We found that presently in Ireland, the mortality rate from severe TBI appears to be higher than that reported in international literature, and only a minority of severe TBI patients are brought directly from the incident to a neurosurgical centre. The new major trauma system should focus on providing effective and efficient access to neurosurgical, neuro-critical and neuro-rehabilitative care for patients who sustain TBI.

Developing a minimum common dataset for hip fracture audit to help countries set up national audits that can support international comparisons.

AIMS: The aim of this study was to explore current use of the Global Fragility Fracture Network (FFN) Minimum Common Dataset (MCD) within established national hip fracture registries, and to propose a revised MCD to enable international benchmarking for hip fracture care. METHODS: We compared all ten established national hip fracture registries: England, Wales, and Northern Ireland; Scotland; Australia and New Zealand; Republic of Ireland; Germany; the Netherlands; Sweden; Norway; Denmark; and Spain. We tabulated all questions included in each registry, and cross-referenced them against the 32 questions of the MCD dataset. Having identified those questions consistently used in the majority of national audits, and which additional fields were used less commonly, we then used consensus methods to establish a revised MCD. RESULTS: A total of 215 unique questions were used across the ten registries. Only 72 (34%) were used in more than one national audit, and only 32 (15%) by more than half of audits. Only one registry used all 32 questions from the 2014 MCD, and five questions were only collected by a single registry. Only 21 of the 32 questions in the MCD were used in the majority of national audits. Only three fields (anaesthetic grade, operation, and date/time of surgery) were used by all ten established audits. We presented these findings at the Asia-Pacific FFN meeting, and used an online questionnaire to capture feedback from expert clinicians from different countries. A draft revision of the MCD was then presented to all 95 nations represented at the Global FFN conference in September 2021, with online feedback again used to finalize the revised MCD. CONCLUSION: The revised MCD will help aspirant nations establish new registry programmes, facilitate the integration of novel analytic techniques and greater multinational collaboration, and serve as an internationally-accepted standard for monitoring and improving hip fracture services.

Impact of COVID-19 on hip fracture care in Ireland: findings from the Irish Hip Fracture Database.

PURPOSE: To describe the impact of COVID-19 on hip fracture care during the first 6 months of the pandemic. METHODS: A secondary analysis of 4385 cases in the Irish Hip Fracture Database from 1st June 2019 to 31st August 2020 was conducted. RESULTS: Hip fracture admissions decreased by 15% during the study period (p < 0.001). Patient characteristics were largely unchanged as the majority of cases occurred in females over 80 years admitted from home. Adherence to many of the Irish Hip Fracture Standards (IHFS) changed following the COVID-19 pandemic. There was an increase in patients admitted to an orthopaedic ward from Emergency Department (ED) within 4 h from 27 to 36% (p < 0.001). However, the proportion of patients reviewed by a geriatrician reduced from 85% pre-COVID to 80% (p < 0.001). Fewer patients received a bone health assessment [90% from 95% (p < 0.001)] and specialist falls assessment [(82% from 88% (p < 0.001)]. No change was seen in time to surgery or incidence of pressure injuries. There was a significant decrease in length of stay from 18 to 14 days (p < 0.001). There was an increase in patients discharged home during the COVID-19 period and a decrease in patients discharged to rehabilitation, convalescence or nursing home care. There was no statistically significant change in mortality. CONCLUSION: Healthcare services were widely restructured during the pandemic, which had implications for hip fracture patients. There was a notable change in compliance with the IHFS. Multidisciplinary teams involved in hip fracture care should be preserved throughout any subsequent waves of the pandemic.

Tranexamic acid for major trauma patients in Ireland.

BACKGROUND: The Clinical Randomisation of an Anti-fibrinolytic in Significant Hemorrhage-2 (CRASH-2) is the largest randomized control trial (RCT) examining circulatory resuscitation for trauma patients to date and concluded a statistically significant reduction in all-cause mortality in patients administered tranexamic acid (TXA) within 3 hours of injury. Since the publication of CRASH-2, significant geographical variance in the use of TXA for trauma patients exists. This study aims to assess TXA use for major trauma patients with hemorrhagic shock in Ireland after the publication of CRASH-2. METHODS: A retrospective cohort study was conducted using data derived from the Trauma Audit and Research Network (TARN). All injured patients in Ireland between January 2013 and December 2018 who had evidence of hemorrhagic shock on presentation (as defined by systolic blood pressure [SBP] <100 mmHg [1 mmHg=0.133 kPa] and administration of blood products) were eligible for inclusion. Death at hospital discharge was the primary outcome. RESULTS: During the study period, a total of 234 patients met the inclusion criteria. Among injured patients presenting with hemorrhagic shock, 133 (56.8%; 95% confidence interval [CI] 50.2%-63.3%) received TXA. Of patients that received TXA, a higher proportion of patients presented with shock index >1 (70.68% vs.57.43%) and higher Injury Severity Score (ISS >25; 49.62% vs. 23.76%). Administration of TXA was not associated with mortality at hospital discharge (odds ratio [OR] 0.86, 95% CI 0.31-2.38). CONCLUSIONS: Among injured Irish patients presenting with hemorrhagic shock, TXA was administered to 56.8% of patients. Patients administered with TXA were on average more severely injured. However, a mortality benefit could not be demonstrated.

IMPACT of COVID-19 on hip fracture services: A global survey by the International Multicentre Project Auditing COVID-19 in Trauma & Orthopaedics.

INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) pandemic resulted in major disruption to hip fracture services. This frail patient group requires specialist care, and disruption to services is likely to result in increases in morbidity, mortality and long-term healthcare costs. AIMS: To assess disruption to hip fracture services during the COVID-19 pandemic. METHODS: A questionnaire was designed for completion by a senior clinician or service manager in each participating unit between April-September 2020. The survey was incorporated into existing national-level audits in Germany (n = 71), Scotland (n = 16), and Ireland (n = 16). Responses from a further 82 units in 11 nations were obtained via an online survey. RESULTS: There were 185 units from 14 countries that returned the survey. 102/160 (63.7%) units reported a worsening of overall service quality, which was attributed predominantly to staff redistribution, reallocation of inpatient areas, and reduced access to surgical facilities. There was a high rate of redeployment of staff to other services: two thirds lost specialist orthopaedic nurses, a third lost orthogeriatrics services, and a quarter lost physiotherapists. Reallocation of inpatient areas resulted in patients being managed by non-specialised teams in generic wards, which increased transit of patients and staff between clinical areas. There was reduced operating department access, with 74/160 (46.2%) centres reporting a >50% reduction. Reduced theatre efficiency was reported by 135/160 (84.4%) and was attributed to staff and resource redistribution, longer anaesthetic and transfer times, and delays for preoperative COVID-19 testing and using personal protective equipment (PPE). CONCLUSION: Hip fracture services were disrupted during the COVID-19 pandemic and this may have a sustained impact on health and social care. Protection of hip fracture services is essential to ensure satisfactory outcomes for this vulnerable patient group.

Paediatric major trauma in the setting of the Irish trauma network.

BACKGROUND: The construction of a new tertiary children's hospital and reconfiguration of its two satellite centres will become the Irish epicentre for all paediatric care including paediatric trauma. Ireland is also currently establishing a national trauma network although further planning of how to manage paediatric trauma in the context of this system is required. This research defines the unknown epidemiology of paediatric major trauma in Ireland to assist strategic planning of a future paediatric major trauma network. METHODS: Data from 1068 paediatric trauma cases was extracted from a longitudinal series of annual cross-sectional studies collected by the Trauma Audit and Research Network (TARN). All paediatric patients between the ages of 0-16 suffering AIS ≥2 injuries in Ireland between 2014-2018 were included. Demographics, injury patterns, hospital care processes and outcomes were analysed. RESULTS: Children were most commonly injured at home (45.1%) or in public places/roads (40.1%). The most frequent mechanisms of trauma were falls <2 m (36.8%) followed by RTAs (24.3%). Limb injuries followed by head injuries were the most often injured body parts. The proportion of head injuries in those aged <1 year is double that of any other age group. Only 21% of patients present directly to a children's hospital and 46% require transfer. Consultant-led emergency care is currently delivered to 41.5% of paediatric major trauma patients, there were 555 (48.2%) patients who required operative intervention and 22.8% who required critical care admission. A significant number of children in Ireland aged 1-5 years die from asphyxia/drowning. The overall mortality rate was 3.8% and was significantly associated with the presence of head injuries (p < 0.001). CONCLUSION: Paediatric Trauma represents a significant childhood burden of mortality and morbidity in Ireland. There are currently several sub-optimal elements of paediatric trauma service delivery that will benefit from the establishment of a trauma network. This research will help guide prevention strategy, policy-making and workforce planning during the establishment of an Irish paediatric trauma network and will act as a benchmark for future comparison studies after the network is implemented.

Trauma on Farms in the Republic of Ireland.

BACKGROUND: Farming is the most dangerous occupation in high-income countries worldwide. However, there is a lack of descriptive literature in this area. Injuries on farms are increasing, at a time when the cohort of trauma patients generally has become older and more medically complex. Farmers continue to work late in life when other industry workers would be retired. This study describes major trauma occurring on farms in the Republic of Ireland, the demographics of patients and treatments they received. METHODS: Data was gathered from the National Office of Clinical Audit Major Trauma Audit (MTA) 2014 to 2016. Patients were included and excluded based on Trauma Audit and Research Network(TARN) inclusion criteria. RESULTS: There were 430 patients included in this study. The median age was 54.5 years (range 1-93). There were 6.3%(n=27) paediatric patients, and 27%(n=116) over 65-year olds. Patients had predominantly low Charlson Comorbidity Index scores (median 0). Patients >65 years had more comorbidities (p<0.001). The median ISS was 9(IQR 9-17). The most common mechanism of injury was blow from animal (n=126,29%) followed by low fall (n=115,27%). Summer was the most common season of injury (n=128,30%) and most patients presented to a hospital between 8am-12am(n=412,96%). There were 11 patients (2.6%) who died after arrival to hospital - most commonly due to head injury (n=5,45%). The median length of stay was six days; older patients stayed longer than younger patients (6 vs 12 days,p<0.001). The most common body area injured was limbs (n=139,32%), followed by chest (n=89,21%), spine (n=67,16%) and head injuries (n=64,15%). There were 84 patients (19.5%) who underwent operative intervention, and 77(18%) required intensive care unit (ICU) admission. Farm trauma patients were more likely to arrive by helicopter than other MTA patients. CONCLUSIONS: A substantial proportion of trauma on Irish farms involves older men who have co-morbidities and complexity of medical need. Farm trauma occurs in rural and remote locations with longer journey times to trauma centres and trauma units-this has implications for trauma care education and mode of EMS transport. Older patients who suffer trauma on farms require longer hospital stays and may not return to independent living.

Early mobilisation reduces the risk of in-hospital mortality following hip fracture.

PURPOSE: Hip fractures are associated with considerable morbidity, excess mortality, and significant healthcare expenditure. There are approximately 3700 hip fractures in Ireland per annum and this figure is set to rise in the next decade in parallel with the ageing population. Approximately 5% of patients who sustain a hip fracture will die in hospital, with less than half of survivors regaining their pre-operative level of function. The authors aimed to identify the determinants of in-hospital mortality post-hip fracture in Ireland 2013-2017. METHODS: A secondary analysis of 15,603 patients in the Irish Hip Fracture Database (IHFD) was conducted. Both descriptive and analytical statistics were produced. Univariate and multivariate logistic regression was carried out. RESULTS: 31% (n = 4796) of patients were male and 69% (n = 10,807) were female. Mean age for males was 75 years (SD 13.5) and 79 years for females (SD 10.5). Median in-hospital mortality was 4.7% (n = 711) (range 2.7-6.2). Univariate logistic regression revealed 11 statistically significant predictors of in-hospital mortality; however, only four remained statistically significant on multivariate analysis [not mobilised day of/after surgery (OR 1.46, 95% CI 1.25-1.70, p < 0.001), independent mobility pre-fracture (OR 0.84, 95% CI 0.79-0.89, p < 0.001), female gender (OR 0.56, 95% CI 0.41-0.76, p < 0.001), and older age (OR 1.05, 95% CI 1.03-1.06, p < 0.01)]. CONCLUSION: Older males with poor pre-fracture mobility who were not mobilised on the day of/after surgery had the highest risk of in-hospital mortality. This research supports the adoption of early mobilisation (day of/after surgery) as a new formal hip fracture standard in keeping with best international practice.

Cycling related major trauma in Ireland.

INTRODUCTION: Cycling as a means of transport or recreational activity is increasing in popularity in Ireland. However, increasing numbers of cyclists may lead to an increased number of bicycle collisions and fatalities. The Road Safety Authority is the statutory body for road safety in Ireland but uses police data alone to collate cycling collision statistics. This may lead to an underestimation of cycling injuries in Ireland. Using hospital statistics may provide a greater understanding of cycling trauma in Ireland. OBJECTIVE: The present study examines cycling related trauma in Ireland using the Major Trauma Audit (MTA) data collected via the Trauma and Research Network (TARN) from hospitals in Ireland for the period 2014 to 2016. The database was interrogated for demographics, mechanism of injury, injury characteristics and patient outcomes. RESULTS: There were 410 cycling collisions recorded in the TARN database which represented 4.4% of trauma captured by TARN for the study period. Of this cohort 79% were male compared with 58% in the overall (TARN) trauma cohort (p < 0.001) and the median (IQR) age was 43.8 years (31.0, 55.7) which is younger than the median (IQR) of 58.9 (36.2, 76.0) years for the overall trauma cohort (p < 0.001). Cycling collisions had a median (IQR) injury severity score (ISS) of 10 (9, 20) which was higher than the overall trauma cohort ISS of 9 (9, 17). Of the mechanisms observed for cycling trauma, 31.7% (n = 130) had a collision with a motor vehicle. Of those who did not wear a helmet, 52.2% (n = 47) sustained a head injury compared with 27.5% (n = 44) in the group who were wearing a helmet (p < 0.001). CONCLUSION: The TARN data presented in this paper builds a more complete overview of the burden of cycling collisions in Ireland. Particular points of focus are that serious cycling injuries occur in a predominantly male population, and that only around 30% of cases are recorded as involving a motor vehicle, with the majority having an unknown mechanism of injury. There was an association between helmets and head injuries in this study, but there are likely other contributing factors such as mechanism of injury, velocity or cycling infrastructure. Using hospital data such as the MTA provides valuable information on the injuries sustained by cyclists, but more prospective studies to capture injury mechanism and contributing factors are needed.
