Effectiveness of an educational video in older adults' perception about falling risks: a randomized clinical trial.
Guilherme Guarino de Moura Sá, Ana Maria Ribeiro Dos Santos, Khelyane Mesquita de Carvalho and 3 others
PMID 35420624WHAT IT FOUND
Verbal nurse guidance raised older adults' fall-risk perception more than an educational video, but the difference was small and not clinically important.
Both groups improved.
Key findings
01Verbal nurse guidance produced a higher post-test fall-risk perception score than the educational video, but the between-group effect size was small and not clinically important.
02Both the video and verbal guidance groups had a statistically significant increase in mean fall-risk perception scores from pre-test to post-test.
03At post-test, the groups differed significantly on only three questionnaire items and were similar on 29 items.

What it does not show
Only fall-risk perception was measured, not actual falls, injury, or behavior change. Follow-up was only 30 days, so longer-term effects are unknown. Participants and the nurses delivering the interventions were not blinded, which may have influenced responses. 22 of 160 allocated participants did not complete the post-test, and the analysis followed per-protocol principles. The sample came from a Brazilian city and Primary Health Care users, so it may not apply to institutionalized older adults or private health services. The between-group difference was statistically significant but small and not clinically important.
The easy way to misread this
Do not conclude that the educational video failed to increase fall-risk perception. Both groups improved, and the difference between video and verbal guidance was small and not clinically important. The study measured perception, not actual falls.
