Feasibility and Acceptability of Using Weighted Blankets to Prevent and /or Mitigate Delirium

To examine the feasibility and acceptability of weighted blankets as a single component, nonpharmacologic strategy to prevent and/or mitigate delirium in an adult medicine critical care patient population. To examine the feasibility and acceptability of videoconferencing (VCU Health Zoom), EHR screening, and VCU and VCU Health infrastructure (REDCap, OnCore) for rural participant recruitment and research participation, remote HealthCare provider protocol training and research engagement, and remote research monitoring and support for rural patient population. To collect preliminary descriptive data and examine trends related to the use of weighted blankets to prevent and/or mitigate delirium to inform future efficacy trials in an adult medicine critical care patient population (e.g., Agitation, Delirium, ICU length of stay, number ventilator days, sedation/opioid medication usage).

Patient Inclusion Criteria:

• 18 years of age or older.
• Requiring ICU level of care.
• Have a primary medical diagnosis.
• Proficient in English.

Patient Exclusion Criteria:

• BMI less than 18.5.

• Known pregnancy.
• Prisoners.
• Presence of skin injury (e.g., surgical wound, pressure injury, moisture injury) in an anatomical location where additional weight/pressure of blanket could prevent healing and /or lead to an expansion of the injury.
• Patients with skin injuries to areas easily left uncovered by the blanket (e.g., hands, feet) can be enrolled with additional communication to clinical team to leave areas uncovered to prevent additional injury.
• Paralysis effecting an area the weighted blanket will cover.
• Current neuromuscular blocking agent.
• Presence of recent/unhealed fractures on an area the blanket will cover (e.g., lower limb long bone, rib, pelvis, spine).
