The facilitators and barriers to implementing virtual visits in intensive care units: A mixed‐methods systematic review

Abstract Background Visitation has a positive effect on patients and families, yet, it can disrupt intensive care unit (ICU) care and increase the risk of patient infections, which previously favoured face‐to‐face visits. The coronavirus disease 2019 (COVID‐19) pandemic has raised the importance of virtual visits and led to their widespread adoption globally, there are still many implementation barriers that need to be improved. Therefore, this review aimed to explore the use of ICU virtual visit technology during the COVID‐19 pandemic and the barriers and facilitators of virtual visits to improve virtual visits in ICUs. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines, six databases (CINAHL, China National Knowledge Infrastructure [CNKI], PubMed, Cochrane, VIP and Wang Fang databases) were searched for empirical studies published between 1 January 2020 and 22 October 2023. Studies that investigated and reported barriers to and facilitators of implementing virtual visits in ICUs during the COVID‐19 pandemic were included. Evidence from the included studies was identified and thematically analysed using Thomas and Harden's three‐step approach. Study quality was appraised with the Mixed‐Methods Appraisal Tool. Results A total of 6770 references were screened, of which 35 studies met the inclusion criteria after a full‐text review. Eight main barriers to virtual visits use were identified: technical difficulties; insufficient resources; lack of physical presence and nonverbal information; low technical literacy; differences in families' perceptions of visual cues; privacy and ethics issues; inequitable access and use of virtual visit technology; and lack of advance preparation. Four facilitating factors of virtual visit use were identified: providing multidimensional professional support; strengthening coordination services; understanding the preferences of patients and their families; and enhancing privacy and security protection. In the quality appraisal of 35 studies, 12 studies were rated as low, five as medium and 18 as high methodological quality. Conclusion This review identified key facilitating factors and barriers to ICU virtual visits, which can foster the development of infrastructure, virtual visiting workflows, guidelines, policies and visiting systems to improve ICU virtual visiting services. Further studies are necessary to identify potential solutions to the identified barriers.
