FEASIBILITY OF A LONGITUDINAL AUDIOVISUAL OBSERVATION PROTOCOL TO CHARACTERIZE LUCIDITY IN ADVANCED AD/ADRD

Abstract Episodes of lucidity (EL) among individuals with advanced dementia, which are predominantly reported near end life, clinically and potentially epidemiologically significant events. Audiovisual observation offers a valuable approach to studying EL, providing opportunities characterize verbal/non-verbal features EL as well their surrounding contexts. Approaches capturing characterizing audiovisual data potential indicators life lacking. We determined the acceptability feasibility multi-faceted observational study protocol people dementia incorporating longitudinal observation, informant field interviews/logs, case review high likelihood Five eligible were enrolled, yielding 100% enrollment/retention rate, 54 observations/140 hours across participants. Task load usability ratings indicate procedures iterative refinements feasible; surveys qualitative appraisal from participants staff endorse rates feasibility.
