Blinding
In the proposed study, only the outcome assessor will be blinded to the group labels. Participants and interventionists are not possible to be blinded in this study. The group labels will not be known to the outcome assessors and will not appear on any documents that the outcome assessors can access. The participants, family members, and staff members of the LTCF are prohibited to disclose the group labels of the participants to the outcome assessors.
