The Risk Assessment Tools for Intraoperative Hypothermia in Adults: A Scope Review

AIMS: To review the global scope of inadvertent intraoperative hypothermia risk assessment tools and to provide a reference for standardising risk assessment. DESIGN: A scoping review. METHODS: Studies on inadvertent intraoperative hypothermia risk assessment tools were systematically searched in Chinese and English databases and guideline websites from their inception up to December 31, 2022. RESULTS: A total of 20 studies were included based on the inclusion and exclusion criteria. The inadvertent intraoperative hypothermia risk assessment tools were categorised into risk prediction models (n = 15), risk assessment tables (n = 4), and risk assessment systems (n = 1). Patient factors were reported in 20 articles, surgical factors were reported in 18 articles, anaesthetic factors were used for evaluation in 16 articles, and environmental factors were reported in 12 articles. Assessment components that were reported more than 10 times included age, body mass index, baseline body temperature, intraoperative fluid volume, surgical duration, anaesthesia duration, and room temperature. IMPACT: Patient and surgical factors are important components of inadvertent intraoperative hypothermia risk assessment tools. Several such tools have been developed, but their reliability and validity need evaluation through multi-center and large-scale clinical studies.
