Background A pilot injury data collection exercise at the emergency departments (EDs) of Oxford University Hospitals National Health Service (NHS) Foundation Trust (OUH) ran from 2012 to 2014 to inform the current development of the new NHS England emergency care data set.
Methods Data collected at the EDs of OUH 1 January 2012 to 30 March 2014 analysed for Oxford City and Cherwell District Council areas. Data completeness and quality checked against Hospital Episode Statistic (HES) returns.
Results Of the 63 877 injury attendances recorded at the 2 sites, 26 536 were unintentional with a home postcode within Oxford City or Cherwell District Council areas. The most frequent location, mechanism, activity and diagnosis were home (39.1% of all unintentional injuries (UIs)), low-level falls (47.1%), leisure (31.1%) and ‘injuries to unspecified part of trunk, limb or body region’ (20.5%), respectively. The most deprived quintile of the population (Index of Multiple Deprivation (IMD) 1) had the highest European Age Standardised Rate (EASR) for all UIs and IMD 5 had the lowest, 54.4 (95% CI 52.3 to 56.5) and 32.2 (31.4 to 33.0) per 1000 person-years, respectively. There was a significant association between increasing levels of deprivation and an increasing incidence rate ratio (IRR) for all UIs, for those in the home, for low-level fall UIs and for non-sport leisure UIs with a particularly sharp increase in the IRR for IMD 1 compared with IMD 5. Sport-related injuries were inversely related to deprivation apart from football.
Conclusions This pilot has demonstrated both the feasibility and importance of prioritising the collection of a national injury data set.
