2 Key findings In Great Britain during 2014, there were 194,477 people injured or killed in a road traffic collision (RTC). Young males (aged 25 years or under) are almost three times more likely to be killed in a car crash than young females. Between April 2012 and March 2015 there were 37,295 Emergency Department (ED) attendances for RTCs across Merseyside and Cheshire. 3,132 attendances were made by residents of St Helens Local Authority (LA). Over this three year period, attendances by St Helens residents for RTCs fell by 50%. The majority of St Helens residents attended Whiston Hospital ED (83%), followed by Warrington Hospital ED (11%) and Aintree Hospital ED (3%). People aged 19 to 31 years accounted for the highest number of attendances, and, unlike other areas, females accounted for more attendances than males in this group. The rate of RTC attendance for people aged 15 to 29 years was 3.1 per 100 population compared to 1.5 for all other groups combined. Across the three years the highest rate of attendances was in July with an average of 10.2 attendances per day; Wednesday had the most RTC attendances overall with 16%; and, attendances peaked between 16:00 and 17:59 (14%). The highest proportion of attendances arrived by private transport (47%) followed by 41% who arrived by ambulance; the majority of attendees self-referred (67%); and, 56% of RTC attendees were discharged with no further treatment required. Road traffic injuries have been neglected from the global health agenda for many years despite being predictable and preventable. Rich and timely data from EDs, analysed by TIIG and applied by community partners may be invaluable in monitoring the prevalence and trends, and identifying those at the highest risk of suffering injuries as a consequence of RTCs. Road traffic collisions in St Helens Road traffic collisions (RTCs) are responsible for causing thousands of injuries and deaths every year. The World Health Organization (WHO, 2015) estimate that globally 1.25 million people die every year as a result of a RTC. Throughout Great Britain during 2014, there were 194,477 people injured or killed in a RTC (Department for Transport, 2015). The majority of individuals were slightly injured (169,895), while 49,164 were either seriously injured or killed. Public Health England s (PHE) Public Health Outcomes Framework (PHOF) indicator reported a rate of 39.7 per 100,000 resident population killed or seriously injured on England s roads across St Helens in (n=210; PHE, 2015). This figure represents a similar rate to the England (39.3) and North West (39.6) averages. WHO (2015) identify age as a potential risk factor for RTCs with road traffic injuries being the leading cause of death amongst those aged between 15 and 29 years. The road safety charity Brake estimate that drivers aged between 17 and 19 years only make up 1.5% of UK licence holders however they are involved in 12% of fatal and serious RTCs (Brake, 2014). WHO (2015) also identify males as more likely to be involved in RTCs than females with 73% of all road traffic deaths occurring amongst men. It is estimated that young males are more likely to be involved in RTCs with men aged under 25 years being almost three times more likely to be killed in a car crash than young females. Research has also been carried out looking at the link between RTCs and levels of deprivation which found that both area and person deprivation was linked to an increased risk of being involved in a serious injury collision (Hurst, 2011). St Helens is a town and metropolitan borough in Merseyside, in the North West of England. According to mid-2014 population estimates, St Helens has a population of 177,188 (ONS, 2015), of which 90,207 (51%) are female and 86,981 (49%) are male. Young men have been identified as being potentially at risk for being involved in RTCs and across St Helens 16,070 people are males aged between 15 and 29 years of age (9% of the whole population).

3 This Trauma and Injury Intelligence Group (TIIG) Local Authority Profile presents RTC injuries sustained by people in St Helens using ED recorded data between April 2012 and March This profile will contextualise ED data by providing an overview of the population, highlighting who is at increased risk of RTCs and describing the specific level of need in St Helens. This profile also provides recommendations for local government and commissioners in terms of the efficient use of resources, and to health and social care Figure 1 shows the majority of RTC attendances were made to Whiston Hospital (2,613; 83%), 11% attended Warrington Hospital (342), 3% University Hospital Aintree (99) and 1% Southport and Formby District General Hospital (32). There was 1% combined attendances from Leighton Hospital (13), Alder Hey Children s Hospital (10), Countess of Chester Hospital (10), Arrowe Park Hospital (9) and Royal Liverpool University Hospital (<5). providers in terms of delivering improved outcomes. Injuries across St Helens, April 2012 to March 2015 Figure 1. RTC attendances by St Helens residents by Emergency Department. For all age groups, between April 2012 and March 2015 there were 51,255 injury attendances made by St Helens residents to Emergency Departments (EDs) across Merseyside and Cheshire. During this period there were 3,132 RTC attendances by St Helens residents to Emergency Departments (EDs) across Merseyside and Cheshire. This figure represents 8% of the total number of attendances for RTCs across all Merseyside and Cheshire EDs (table 1). Between April 2012 and March 2015, attendances for RTCs by St Helens residents fell by 50%. Table 1.

10 Summary and Recommendations St Helens had the lowest number of RTCs in Merseyside and Cheshire, but an average overall rate of 1.9 per 100 population. Accidents were found to be clustered around St Helens town and the south of the LA. There was a substantial drop in RTCs between April 2012 and March 2015 (50%); this decrease was the largest of all LAs in Merseyside and Cheshire. Unlike other LAs, females accounted for more ED attendances than males for people aged 15 to 29 years but the difference was not substantial. Educational messages and road safety awareness campaigns should be particularly tailored to young adults (aged 15 to 29 years) since the RTC rate for this group was more than double other age and gender groups combined. There was an association between deprivation and RTC rate, which may require further exploration. St Helens LA may also consider further exploration of specific LSOAs identified as having high rates of RTCs. Consider mechanisms to enable the EDs in Cheshire and Merseyside to categorise further data items relating to RTCs. For example, whether the attendee was in a vehicle or was a pedestrian and, if in a vehicle, whether the attendee was the driver or the passenger, and whether the attendee was wearing a seatbelt or not. This can be achieved through multi-agency meetings and dialogue, primarily between the TIIG team and EDs. A potential barrier may be the IT systems used by EDs (and the costs involved in potentially changing them), which may be overcome with cooperative action and by highlighting the importance of such data in informing prevention strategies and road safety campaigns. Similarly consider improving the location details to include specific roads or streets in order to identify accident hotspot areas. Analysis of this data would be valuable in predicting where accidents are likely to occur and initiating safety measures and precautions. Road traffic injuries have been neglected from the global health agenda for many years (WHO, 2015), despite being predictable and largely preventable. Evidence from many countries shows that dramatic successes in preventing road traffic crashes can be achieved through concerted efforts that involve, but are not limited to, the health sector. Rich and timely data from EDs, analysed by TIIG and applied by community partners may be invaluable in monitoring the prevalence and trends, and identifying those at the highest risk of suffering injuries as a consequence of RTCs. This information can then be used to inform the targeting and planning of appropriate interventions across a range of behavioural risk factors including speed, drink driving, mobile phone use, seat belt and helmet use and child restraints (WHO, 2015). These recommendations are unlikely to be achieved without sustained working between cooperating agencies. However their implementation would be likely to reduce the number of RTCs in St Helens and the burden on EDs in Merseyside and Cheshire. Local Authority Profile St Helens Page 9
