A scoping review analyzed the research on communication between general practitioners and deaf patients, focusing on sign language use. The study aimed to identify gaps in the literature regarding communication in general practice. Researchers searched databases including CINAHL, PubMed, and Web of Science, reviewing 2,060 publications and examining 86 full texts. Ultimately, seven studies were included, with four using quantitative surveys targeting doctors and deaf patients, two qualitative studies focusing on deaf individuals and sign language interpreters, and one mixed-methods study involving deaf patients. Key findings highlighted five areas needing further research: perceived communication problems by deaf patients, general practitioners’ perspectives, strategies for enhancing communication, the role of sign language interpreters, and the effects of communication barriers. The literature indicates a lack of knowledge among general practitioners about effectively communicating with deaf patients. Strategies to address communication issues are often insufficient, and the use of qualified sign language interpreters in general practice is rare. Additionally, there is a significant lack of reliable statistics on interpreter usage in the German healthcare system, indicating a need for more research in this area.
