Background:
Major trauma (MT) is a significant cause of morbidity and mortality worldwide, with older adult patients facing unique challenges due to age-related vulnerabilities and higher risks of falls. This study aimed to investigate differences in trauma characteristics, injury mechanisms, and outcomes of older adults compared to all younger patients with MT on a national level.
Methods:
This retrospective cohort study analysed the national Major Trauma Audit data from 23,765 eligible patients with MT in Ireland of all ages and stratified into two age groups: those under 65 years (n = 12,620) and those aged 65 years or older (n = 11,145). The Major Trauma Audit follows the methodology of National Major Trauma Registry in the UK. Variables assessed included injury severity, comorbidities, length of stay (LOS), and mortality rates. Statistical comparisons were made between the two age groups.
Results:
Older adults represent 47 % of the total Irish patient population with MT, with a significantly higher proportion of females (56 %) compared to younger patients (31 %) (P<0.001). Falls of less than two meters were the leading mechanism of injury for older adults (82 %), while road traffic accidents (RTA) were more common among younger patients (25 %). Severe injuries were observed in 34 % of both age groups, but <10 % of older adults were received by a trauma team. Comorbidities were significantly more prevalent in older adults (75 %) compared to 39 % in younger patients, (P<0.001). Median hospital LOS was twelve days for older adults, compared to seven days for younger patients. Mortality rates were significantly higher among the older patient population, who were also more likely to be discharged to long-term care, (P<0.001).
Conclusion:
In comparison to younger patients, the present study highlights that older adults who experience major trauma are frequently under-triaged as suspected MT, leading to delays in care, inadequate treatment, or worse clinical outcomes.
