RESUMEN
OBJECTIVE: This systematic review appraises, synthesises, and presents the published evidence on the effect of patient education videos in modifying medication-related health behaviours. METHODS: A systematic literature review was conducted across 12 databases. Title, abstract and full-text screening was done independently using PICOS. Data extraction results were mapped directly to the Behaviour Change Intervention Functions. Results are reported in accordance with PRISMA 2020. RESULTS: Out of 583 studies 12 articles from 4 countries were included. Interventions focus on improving patient's knowledge. Modelling, Enablement, Persuasion, and Training are used in video education development. PASS analysis showed very few well designed studies that allow the reliable determination of behaviour changes. CONCLUSIONS: A reliable or sustained effect of patient education videos in modifying medication-related health behaviours could not be reported due to a lack of robust study design. Modelling, Enablement, Persuasion, and Training are all intervention designs used to target behaviour change often resulting either in a narrative (real people acting) or practice (demonstrating) presentation format. PRACTICE IMPLICATIONS: With the increased use of health education technology, robust, theoretically underpinned studies are urgently needed to evaluate the effectiveness of these interventions in the context of their impact on patient medication-related behaviour change.
