Audiovisual aids in primary healthcare settings' waiting rooms. A systematic review.

BACKGROUND: Health promotion is part of GPs' commitments. Some waiting rooms have therefore been implemented with audiovisual aids (posters, pamphlets or screens) for health promotion purposes. Few studies have assessed the effect of audiovisual aids in primary care.

OBJECTIVES: To identify, describe and appraise studies that have investigated the effects of audiovisual aids on health promotion in primary healthcare waiting rooms. To determine which factors influence this impact through literature review.

METHODS: Systematic review. Two independent researchers using predefined keywords searched databases. Additional publications were extracted from the reference lists of the selected articles. The selection of the articles was performed on the title and abstract, followed by complete reading and assessment. Bias and level of evidence were analysed.

RESULTS: A total of 909 articles were collected. Most of them were not in primary care settings. Fourteen peer-reviewed articles fully meeting inclusion criteria were included and analysed. Good quality studies were scarce. Eight of these articles using videos or slideshows on TV screens or tablets indicated effects: three of them were significant on patient knowledge with acceptable evidence and three on health behaviour on surrogate endpoints. Audiovisual aids seem to be used or noticed by patients and can induce conversations with physicians. The relevant factors that might influence these effects (duration of exposure, conception quality, theme, target population and time spent in the waiting room) are insufficiently investigated.

CONCLUSION: Audiovisual aids broadcasting messages using screens (TVs, computers, tablets, and smartphones with Bluetooth® pairing) probably enhance patients' knowledge. A change in health behaviour remains controversial.
