| Variable | OR (95% CI) | p value |
|---|---|---|
| ATLS 8th edition | 0.85 (0.47–1.53) | 0.60 |
| ATLS 9th edition | 0.66 (0.38–1.11) | 0.12 |
| PALS | 2.07 (1.32–3.26) | 0.001 |
| Previous IO device training | 4.02 (1.06–15.34) | 0.040 |
| Experience with IO devices for vascular access purposes | 1.80 (1.09–2.99) | 0.020 |
| Access to an IO device | 2.50 (0.61–10.26) | 0.20 |
ATLS = Advanced Trauma Life Support; CI = confidence interval; IO = Intraosseous; OR = odds ratio; PALS = Pediatric Advanced Life Support.
