Purpose Pharyngeal residue rating scales are often used to rate pharyngeal residue observed during flexible endoscopic evaluation of swallowing. Despite the widespread use of pharyngeal residue rating scales, there is no data that has systematically explored user experience. The aim of this scoping review was to investigate specific reporting of user experience, user centred design principles, and normative data in the development of pharyngeal residue rating scales. Method A scoping review was conducted across four electronic databases inclusive of all dates until June 2024. Grey literature searching occurred in March–April 2023 and was repeated in June 2024. This review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) protocol. Titles/abstracts, full texts, and data extraction were reviewed by two independent reviewers. Result A total of 22 sources were included, with 18 unique pharyngeal residue rating scales identified. Two studies referred to user experience, seven included at least one user centred design principle, and four studies reported on normative data. Conclusion The findings of this review highlight few pharyngeal residue rating scales include the experience of the intended user and establish normative data in the initial development phase. User experience, user centred design principles, and normative data may be useful considerations to optimise functionality.
