Aim:
To evaluate the safety, feasibility and acceptability of weighted blankets for patients with dementia who experience agitation in acute care.
Design:
Randomised controlled trial.
Methods:
Patients with dementia experiencing agitation at a single hospital were recruited between May 2023 and January 2024. Participants were randomly assigned to the intervention (weighted blanket) or control (standard care) group. Agitation scores, vital signs, skin integrity, pharmacological interventions and general observations were recorded at baseline and at 15-, 30-, 60- and 75-min (or 15-min post-blanket removal) post-baseline. Nursing staff completed a survey on the intervention's acceptability, appropriateness and feasibility.
Results:
There was a recruitment rate of 86.7%, 70% of patients tolerated the intervention for the full duration. Nursing staff agreed the intervention was appropriate (100%), acceptable (100%) and feasible (92.9%). The intervention reduced patient heart and respiratory rates. No significant impact on patient temperature, oxygen saturations, skin integrity or risk of falls was found. The intervention reduced agitation scores, pharmacological and non-pharmacological interventions.
Conclusion:
Weighted blankets in acute care settings are safe and have some effect on agitation and pharmacological use. Staff found the use of weighted blankets to be acceptable and most patients tolerated use of the blankets without increased risk of adverse events.
Implications For Profession/Patient Care:
This study provides evidence that weighted blankets may be used safely with the acceptance of patients with dementia and staff in hospitals.
Impact:
This study addressed the use of weighted blankets for persons with dementia who are experiencing agitation and found that they are safe and feasible for use in acute care. Future research is feasible and should focus on blanket weight dosing and the effect on agitation, pharmacological and non-pharmacological interventions.
Reporting Method:
Adheres to the CONSORT 2010 checklist for a feasibility trial.
Patient/Public Contribution:
Patients and public did not contribute to this study.
