Do health service waiting areas contribute to the health literacy of consumers? A scoping review

Health service waiting areas commonly provide health information, resources and supports for consumers; however, the effect on health literacy and related outcomes remains unclear. This scoping review of the literature aimed to explore the use of waiting areas as a place to contribute to the health literacy and related outcomes of consumers attending health appointments. Articles were included if they focussed on health literacy or health literacy responsiveness (concept) in outpatient or primary care health service waiting areas (context) for adult consumers (population) and were published after 2010. Ten bibliographic databases, one full-text archive, dissertation repositories and web sources were searched. The search yielded 5095 records. After duplicate removal, 3942 title/abstract records were screened and 360 full-text records assessed. Data were charted into a standardized data extraction tool. A total of 116 unique articles (published empirical and grey literature) were included. Most articles were set in primary and community care (49%) waiting areas. A diverse range of health topics and resource types were available, but results demonstrated they were not always used by consumers. Outcomes measured in intervention studies were health knowledge, intentions and other psychological factors, self-reported and observed behaviours, clinical outcomes and health service utilization. Intervention studies overall demonstrated positive trends in health literacy-related outcomes, although the benefit declined after 3-6 months. Research on using waiting areas for health literacy purposes is increasing globally. Future research investigating the needs of consumers to inform optimal intervention design is needed.
