Discussion
This is the first study to evaluate parent and caregiver utilization of
educational YouTube videos in pediatric HSCT. We found, that on average,
40-70% of each video is viewed. The average watch percentage can
provide insight into what happens once viewing begins. The difference in
watch percentage between the languages concerned as well as non-English
videos (Spanish and Arabic) had a lower mean watch percentage than their
English equivalents. Non-English versions of videos are typically
longer, and the correlation between video length and average watch time
is negative, but also weak (-0.352), suggesting that other factors are
likely contributing to their poor performance.
We can ask important questions about our system by using views per
patient data as a proxy metric for our education delivery processes. Are
we seeing the number of views we would expect given the number of
transplants we perform? Is there a system-level reason why video topic
or language differences exist?
In next steps, our team will examine our video delivery processes to
ensure system reliability and survey our patients and families to
identify barriers to watching the current videos. We anticipate that
these efforts will present change opportunities both in the system and
content areas.
Limitations:
Exactly what YouTube records as a “view” isn’t technically known to
the public to discourage attempts to inflate view counts. Estimating
viewers from view counts is inexact. A video’s view count would be the
same if 50 people watched once or 25 people watched twice. We also do
not know if the person watching the video is a patient or family member.
While the videos are not searchable or recommended on YouTube, links to
the videos are posted on our public website enabling access to those
other than our patients and families.
