Abstract:

Objective To systematically search，evaluate，and summarize the relevant evidence of the use of support surface in long-term bedridden patients，so as to provide the basis for the clinical position management of long-term bedridden patients. Methods Clinical decisions，best practices，guidelines，expert consensus，systematic review and evidence summary were searched from domestic and foreign databases and websites according to literature quality assessment. The search period was up to July 20，2023. Results A total of 13 literatures were included，including two clinical decisions，four guidelines，five systematic reviews and two best evidence summaries. Finally，30 pieces of evidence were summarized into four aspects：patient evaluation，support surface selection，support surface placement and precautions. Conclusion This article summarized the prevention and treatment effects of supports with different functions，materials，shapes and surface coverings on stress injuries，and suggested that clinical nurses should be familiar with the functions and usage of various types of support surfaces，and evaluate the selection and placement of corresponding support surfaces for different patients，so as to effectively prevent the occurrence of stress injuries and improve patient comfort.
