Temporal variation in major trauma admissions.

ABSTRACT

INTRODUCTION: Trauma is a significant cause of morbidity and mortality in the UK. Since the inception of the trauma networks, little is known of the temporal pattern of trauma admissions. METHODS: Trauma Audit and Research Network data for 1 April 2011 to 31 March 2013 were collated from two large major trauma centres (MTCs) in the South East of England Brighton and Sussex University Hospitals NHS Trust (BSUH) and St George's University Hospitals NHS Foundation Trust (SGU). The number of admissions and the injury severity score by time of admission, by weekdays versus weekend and by month/season were analysed. RESULTS: There were 1,223 admissions at BSUH and 1,241 at SGU. There was significant variation by time of admission; there were more admissions in the afternoons (BSUH p<0.001) and evenings (SGU p<0.001). There were proportionally more admissions at the weekends than on weekdays (BSUH p<0.001, SGU p=0.028). There was significant seasonal variation in admissions at BSUH (p<0.001) with more admissions in summer and autumn. No significant seasonal variation was observed at SGU (p=0.543). CONCLUSIONS: The temporal patterns observed were different for each MTC with important implications for resource planning of trauma care. This study identified differing needs for different MTCs and resource planning should be individualised to the network.
