Introduction: The use of adaptations for positioning in bed is relevant in the
hospitalization process, which among them are the support surfaces, as they have the
objective of relieving and/or redistributing the pressure in the body. Objective: Identify and
analyze scientific evidence about the effectiveness of support surfaces in preventing
pressure injuries in hospitalized patients. Method: This study is a systematic quantitative
review based on the PRISMA guidelines. Searches were performed in the Cochrane
Library, OTSeeker, PubMed and Embase databases, using the following combination of
terms: ‘‘Support surface’’ OR Mattresses AND ‘‘Pressure Ulcer’’ OR Bedsore OR
‘’Pressure Sore’’ OR ‘‘Decubitus ulcer’’ AND Hospital OR Hospitals. Texts in English
published between 2013 and 2022 were included. Two researchers performed the
literature searches and independently extracted data from the studies and the
concordance was submitted to Kappa analysis. The level of evidence and methodological
quality of the included studies were assessed using the PEDro scale and the Cochrane
risk of bias tool, respectively. Results: Studies evaluated alternating pressure air support
surfaces, reactive air, foam, motorized, gel and water . It was highlighted that the devices
have uncertain effectiveness in preventing pressure injury (PI). Conclusion: Alternating
pressure air surfaces and foam surfaces showed significant results in decreasing injury in
critically ill patients, that future studies may carry out a priority assessment and guide
professionals to make current clinical recommendations and assist in the development of
new types of devices.
