Video-based decision aids (DA) show positive patient outcomes across various medical fields. Further research is needed to address knowledge gaps and improve generalizability for these valuable tools.
Area of Science:
- Health communication
- Medical informatics
- Patient engagement
Background:
- Video-based decision aids (DA) are increasingly evaluated for patient use.
- These tools aim to improve patient understanding and involvement in medical choices.
Purpose of the Study:
- To systematically review the literature on video-based patient DA.
- To identify medical areas, decisions, impacts, study locations, and publication trends.
Main Methods:
- Systematic literature review using multiple databases (Medline, Embase, CINAHL, PsychInfo, Pubmed).
- Inclusion of studies from inception to 2016, with reference and journal searches.
Main Results:
- 488 studies were analyzed, focusing on cancer screening, risk reduction, advance care planning, and adherence.
- Most studies were in the US, with small sample sizes, reporting generally positive outcomes.
- Publication rates have significantly increased since the 1990s.
Conclusions:
- Video-based DA represent largely positive interventions for patients.
- Knowledge gaps remain, particularly concerning generalizability across diverse populations.
