COACHing people with dementia to better self care
Researchers from Canada and Scotland studied an automated system designed to assist people with dementia get through activities of daily living –- in this case hand washing -– and reduce caregiver burden.
First, the details.
- 6 older adults with moderate-to-severe dementia participated.
- Hand washing was the target activity of daily living.
- They washed their hands once with the help of a caregiver and then alone.
- Washing was divided into 5 steps.
- The participants were monitored using real time video.
- Data from the video were analyzed using a computer.
- Missed washing steps triggered an audio and/or video prompt that guided the participant to correct the missed step.
And, the results.
- Using COACH, participants were able to complete 11% more hand washing steps independently.
- They required 60% fewer interactions with a human caregiver.
- 4 participants achieved complete or very close to complete independence.
- Interestingly, participants’ mini mental state exam (MMSE) scores did not appear to coincide with hand washing performance and/or responsiveness to COACH.
- 78% of COACH’s actions were considered clinically accurate.
The bottom line?
The authors concluded, “The COACH system shows promise as a tool to help support older adults with moderate-levels of dementia and their caregivers.”
One small step for COACH, but a potentially giant step for future caregivers.
