简介:AbstractThe treatment of severe trauma, especially multiple injuries, requires multidisciplinary collaboration. The current study aims to highlight the challenges of consultation mode for severe trauma in general hospitals and emphasizes the need to create a new temporary-sustainable team. It suggests developing an information consultation mode and enforcing the fine management to improve the quality and safety of the medical treatment. The management mode of a temporary-sustainable team will reduce the cost and improve the treatment efficiency. Overall, a temporary-sustainable team has significant advantages over a traditional multidisciplinary team for severe trauma treatment.
