Severe head injury in elderly: 6-year comparison of treatment and outcome between southern Finland and Navarra (Spain)
To compare the profile, treatment and outcome of elderly patients with severe traumatic brain injuries (TBI) between southern Finland and Navarra (Spain).
Data collected from, 2010 to 2015, in the Major Trauma Registry of Navarra (MTR-N) and the Helsinki Trauma Registry (HTR) were compared. Patients with New Injury Severity Score (NISS) ≥ 16 and age ≥ 65 with isolated severe TBI were considered. Patients who had been admitted to the hospital ≥ 24 h after the trauma, had been pronounced dead before hospital arrival, or had been injured by hanging, drowning or burns, were excluded. Outcome was defined by 30-day hospital mortality. The expected mortality was calculated using the Revised Injury Severity Classification score II (RISC II). Other compared data included demographics, injury mechanism, pre-hospital and hospital treatment, and time intervals.
A total of 305 (MTR-N) and 137 (HTR) patients were included in the outcome analysis. The standardized mortality ratio with 95% confidence interval was for MTR-N 1.4 (1.1–1.6) and for HTR 0.8 (0.6–1.1). Patients in Navarra were older (average 79.7 vs. 75.0) while in southern Finland the percentage of pre-hospital intubation in patients with GCS ≤ 8 (75.0% vs 50.0%) and ICU admission (72.2% vs 22.0%) were higher.
The better adjusted outcome of elderly patients with severe TBI in southern Finland in comparison to Navarra could be due to higher rate of pre-hospital intubation and/or higher rate of ICU admissions in southern Finland. Increasing number of elderly patients with severe TBI necessitate uniformly accepted protocols in pre- and in-hospital management.
