Systematic review of prediction models for post-traumatic hypothermia risk.

Summary: When someone gets severely injured, their body temperature can drop dangerously low. This is called "post-traumatic hypothermia." It happens to more than half of severely injured patients and makes it twice as likely they will not survive. Doctors use special checklists or "prediction models" to guess who is at the highest risk of getting too cold.

Researchers looked at 9 of these models to see how well they work. They found that things like cold weather, wet clothes, giving IV fluids, and severe injuries are big warning signs. While the models are pretty good at guessing who will get too cold, the studies behind them aren't perfect and have flaws. Doctors need bigger and better studies before they can fully trust these tools to save lives.
