A Survey of Accidental Hypothermia Knowledge among Navy Members in China and the Implications for Training

OBJECTIVES Accidental hypothermia (AH) is a potentially life-threatening condition that can lead to significant morbidity and life-long effects. Navy personnel are always at a greater risk of AH due to frequent outdoor work, wilderness exposure, prolonged immobility and exhaustion. The purpose of the survey was to assess Chinese Navy members' awareness of AH and to make recommendations with regard to better measures for improving it. METHODS 111 Navy members completed a written questionnaire that was subsequently analyzed. RESULTS 30.6% of the respondents have experienced AH and 64.9% rated their knowledge of AH as "low" or "none". Over half of them identified the initial symptom of AH as obvious shivering (69.4%) and apathy (45.0%). As for the aggravate symptoms, 60.9% chose the wrong answer of more obvious shivering instead of the right one-absence of shivering (5.4%). In the case of the treatment of mild AH, more than half of the respondents chose the wrong answers. CONCLUSIONS This study suggests that the basic skills of recognition and treatment of AH are inadequate in the Chinese Navy. Further work is required to develop a systematical, comprehensive and corresponding education method that would promote correct actions during AH.
