The Effects of a Model-based Sensory Stimulation Intervention on Preventing Delirium Among Intensive Care Unit Patients: A Randomised Controlled Trial

Sensory stimulation can be formed in different aspects, and the most important ones are visual stimulation and auditory stimulation. Visual stimulation interventions involved providing a calendar, clock or familiar objects such as photographs of family caregivers; while auditory stimulation included calling the name of patients, helping to orientate the time and location, introducing hospital information, the ICU surrounding and treatment, and communicating with patients, who could not talk due to artificial airway, through a blackboard and use of gestures.
