Does Telehealth Delivery of a Dyadic Dementia Care Program Provide a Noninferior Alternative to Face-To-Face Delivery of the Same Program? A Randomized, Controlled Trial

Abstract

ObjectiveThis study aimed to determine whether delivery of a dyadic intervention using telehealth was noninferior to delivery of the same program using traditional face-to-face delivery through home visits. DesignWe conducted a noninferiority randomized controlled trial. ParticipantsParticipants had a diagnosis of dementia, were living in the community, and had an informal caregiver who reported difficulties in managing activities of daily living or behavioral symptoms. InterventionParticipants were randomized to receive either telehealth or home visit delivery of the same intervention program. MeasurementsThe primary outcome was the Caregiving Mastery Index, secondary outcomes included caregiver's perceptions of change, activities of daily living function, and type and frequency of behavioral symptoms of persons living with dementia. Therapists delivering the intervention recorded the time spent delivering the intervention as well as travel time. ResultsSixty-three dyads were recruited and randomized. Both groups reported improvements for the primary outcome, however, these were not statistically significant. There were no significant differences between groups for the primary outcome (mean difference 0.09 (95% confidence interval −1.26 to 1.45) or the secondary outcomes at 4 months. Both groups reported significant improvements in caregiver's perceptions of change. The amount of time spent delivering the content of the program was similar between groups, however offering the intervention via telehealth significantly reduced travel time (mean 255.9 minutes versus mean 77.2 minutes, p <0.0001). ConclusionIt is feasible to offer dyadic interventions via telehealth and doing so reduces travel time and results in similar benefits for families.
