Biomechanical Evaluation of Friction-Reducing Devices for Lateral Patient Transfers

Purpose: To evaluate the efficacy of friction-reducing devices used for lateral patient transfers.

Methods: A mannequin used to represent a dependent patient was transferred laterally from bed to stretcher. One male investigator repeated this transfer task using eleven comparable lateral transfer aids or techniques. Applied force was measured using a Chatillon dynamometer; postural analysis was prepared from still photography.

Results: Mean applied force, spinal forces, and population strength capabilities were calculated, based on which Lateral Transfer Aid by Phil-e-Slide was deemed to be Best-in-Class.

Conclusion: The most efficacious mechanism for lateral patient transfers provided extendable pull straps, low friction material and optimal location of handles on the device.

Clinical Relevance:
Findings of this study aid caregivers in the selection of appropriate technologies to be used during lateral transfer of patients. These devices improve patient safety, while also affording a lesser risk of back injury to the caregiver.
