Impact of Rewarming Rate on the Mortality of Patients with Accidental Hypothermia

Impact of Rewarming Rate on the Mortality of Patients with Accidental Hypothermia

In this study, we found that overall, in-hospital mortality rates increase with each 0.5 °C/h decrease in rewarming rate (RR). However, judging from the results of subgroup analyses, the safest RR might differ according to the patient status or rewarming methods.

During the study, 572 patients were registered in the J-Point registry, and 481 patients were included in the analysis.

The median body temperature on arrival to the hospital was 30.7°C.

This was a multicentre chart review study of patients with accidental hypothermia (AH) visiting the emergency department of 12 institutions in Japan from April 2011 to March 2016.

We retrospectively registered patients using the International Classification of Diseases, Tenth Revision code T68: “hypothermia”.

We excluded patients whose body temperatures were unknown or ≥ 35°C, who could not be rewarmed, whose rewarmed temperature or rewarming time was unknown, those aged < 18 years, or who or whose family members had refused to join the registry.
