(Batesville, IN, USA).Head-of-bed (HOB) elevation is a common clinical practice in hospitals causing the patient's body to slide down in bed because of gravity. This migration effect likely results in tissue shearing between the sacrum and the support surface, which increases the risk for pressure injuries. StayInPlace (HillRom Inc.) is a commercial migration-reduction technology (MRT) incorporated in intensive care bedframes. Yet, the effects of migration-reduction on tissue shear stresses during HOB elevation are unknown. We analysed relationships between migration and resulting sacral soft tissue stresses by combining motion analysis and three-dimensional finite element modelling of the buttocks. Migration data were collected for 10 subjects, lying supine on two bedframe types with and without MRT, and at HOInternational wound journal631-640https://www.ebi.ac.uk/biostudies/studies/S-EPMC7217162biostudies-literatureHow patient migration in bed affects the sacral soft tissue loading and thereby the risk for a hospital-acquired pressure injury.PMC7217162Gefen ALustig MWiggermann NfalseHow patient migration in bed affects the sacral soft tissue loading and thereby the risk for a hospital-acquired pressure injury.Head-of-bed (HOB) elevation is a common clinical practice in hospitals causing the patient's body to slide down in bed because of gravity.
