PROTOCOL: Utilisation of Genetics and Genomics in Primary Care: Protocol for an Evidence and Gap Map

This protocol describes a Campbell evidence and gap map designed to visually map existing evidence on the application of genetic and genomic testing in primary care. Beyond outlining the rationale and motivation, this protocol details the methodological steps and rigorous criteria that will guide its development. These include: 1) conducting a systematic search to identify published literature on the use of genetic and genomic testing in primary care; 2) summarising and visually mapping the available evidence; and 3) identifying gaps in the current evidence base to inform future research priorities and policy directions. The resulting map is expected to provide a rigorous yet accessible tool for researchers, practitioners, and policymakers seeking to assess the current evidence landscape and identify opportunities to integrate genetics and genomics into routine healthcare delivery.
