Background Genetic screening (GS), defined as the clinical testing of a population to identify asymptomatic individuals with the aim of providing those identified as high risk with prevention, early treatment, or reproductive options. Genetic screening (GS) improves patient outcomes and is accessible to the community. Family physicians (FPs) are ideally placed to offer GS. There is a need for FPs to adopt GS to address anticipated genetic specialist shortages. Objective To explore FP attitudes, perceived roles, motivators and barriers, towards GS; and explore similarities and differences between private and public sector FPs. Methods We developed a semi-structured interview guide using existing literature. We interviewed private and public sector FPs recruited by purposive, convenience and snowballing strategies, by telephone or video to theme saturation. All sessions were audio-recorded, transcribed and coded for themes by two independent researchers with an adjudicator. Results Thirty FPs were interviewed (15 private, 15 public). Theme saturation was reached for each group. A total of 12 themes (6 common, 3 from private-practice participants, 3 public-employed participants) emerged. Six common major themes emerged: personal lack of training and experience, roles and relevance of GS to family medicine, reluctance and resistance to adding GS to practice, FP motivations for adoption, patient factors as barrier, and potential solutions. Three themes (all facilitators) were unique to the private group: strong rapport with patients, high practice autonomy, and high patient literacy. Three themes (all barriers) were unique to the public group: lack of control, patients’ lower socioeconomic status, and rigid administrative infrastructure. Conclusion FPs are motivated to incorporate GS but need support for implementation. Policy-makers should consider the practice setting when introducing new screening functions. Strategies to change FP behaviours should be sensitive to their sense of autonomy, and the external factors (either as facilitators or as barriers) shaping FP practices in a given clinical setting.

ObjectiveThe proliferation and growing demands of genetic testing are anticipated to revolutionise medical practice. As gatekeepers of healthcare systems, general practitioners (GPs) are expected to play a critical role in the provision of clinical genetic services. This paper aims to review existing literature on GPs’ experience, attitudes and needs towards clinical genetic services.DesignA systematic mixed studies review of papers published between 2010 and 2022.Eligibility criteriaThe inclusion criterion was peer-reviewed articles in English and related to GPs’ experience, views and needs on any genetic testing.Information sourcesThe PubMed, PsycINFO, Cochrane, EMBASE databases were searched using Mesh terms, Boolean and wildcards combinations to identify peer-reviewed articles published from 2010 to 2022. Study quality was assessed using Mixed Methods Appraisal Tool. Only articles that fulfilled the inclusion criteria were selected. A thematic meta-synthesis was conducted on the final sample of selected articles to identify key themes.ResultsA total of 62 articles were included in the review. Uncertainty over GPs’ role in providing genetic services were attributed by the lack of confidence and time constraints and rarity of cases may further exacerbate their reluctance to shoulder an expanded role in clinical genetics. Although educational interventions were found to increasing GPs’ knowledge and confidence to carry out genetic tasks, varied interest on genetic testing and preference for a shared care model with other genetic health professionals have resulted in minimal translation to clinical adoption.ConclusionThis review highlights the need for deeper exploration of GPs’ varied experience and attitudes towards clinical genetic services to better facilitate targeted intervention in the adoption of clinical genetics.
