Vascular-access interventions are necessary for the continuation of hemodialysis, and they are performed under X-ray guidance. During interventions, patients’ accidental falls from the bed are a serious problem, and spe-cialized fixation systems for hemodialysis patients to prevent their falls from the bed have been lacking. We developed a new fixation plate made of polypropylene homopolymer and tested its ability to prevent such falls retrospectively. This plate, which we named the ‘vascular-access intervention assistance plate,’ offers functional features such as the concurrent fixation of the body and either arm and an arm space with serrations for fixing a forearm strap. We performed computer simulations to examine the strength of the plate, and we evaluated the efficacy of fall prevention by reviewing patients’ medical records. The results demonstrated that the functional design of the plate provides good operability via accurate concurrent fixations of the body and arm. The com-puter simulation analysis results indicated the plate’s sufficient strength. The medical records analysis revealed three accidental falls before the plate’s introduction (401 patients, 1,437 interventions), and none after plate introduction (683 patients, 1,872 interventions). Accidental falls were significantly prevented by use of the plate (p < 0.05). The dementia rate and type of procedure were not significantly different between the patients who fell and those who did not. This vascular-access intervention assisted plate provides good operability and safety by preventing accidental falls among hemodialysis patients.
