Findings are reported on risk factors for hospital-associated VTE in critically ill children.
Risk factors identified were central line, length-of-stay ≥ 4 days, and significant infection.
These risk factors yield a novel risk score (total 15 points) for HA-VTE in critically ill children.
It is proposed that a score of 15 points would warrant pharmacological prophylaxis.
If prospectively validated, this score will inform the design of future pediatric VTE prevention trials.
