About

Delirium is highly associated with adverse clinical outcomes of intensive care unit (ICU) patients, including increased cognitive impairment, duration of intubation, ICU length of stay, mortality, physical dependence, and health care costs. This randomised controlled study will firstly develop a family-supported sensory stimulation package based on the literature review as well as the findings of the cross-sectional survey and the in-depth interview. The intervention effects than will be evaluated using outcomes including delirium incidence, delirium duration, delirium severity, ICU patients' consciousness and cognitive function as well as family members' satisfaction and anxiety. This study is expected to provide evidence of the effectiveness of family-supported sensory stimulation on preventing delirium among ICU patients.

152 participants in 2 patient groups

Sensory stimulation

Experimental group

Description:

Participants allocated to the intervention group will receive a model-based sensory stimulation intervention, which is aimed at providing visual and auditory stimulation to ICU patients with additional support from family caregivers.

Treatment:

Other: Sensory stimulation

Usual care

No Intervention group

Description:

Participants in the control group will receive usual care routine that they are receiving or planning to receive. The registered ICU nurses will provide the same nursing care as previously, including but not limiting to the use of sedation, analgesia, spontaneous breathing trial, indwelling catheter, feeding, and bowel care.
