Public perspectives on healthcare professional-directed communication of hereditary genetic risks: a mixed-method...

Genetic testing has revolutionized the identification of individuals at increased risk for various hereditary conditions, enabling early intervention and preventive measures. However, effective cascade counseling and testing depends on successful intra-familial communication. This mixed-method systematic review aimed to explore the general population's perspectives and preferences regarding the communication of potential genetic risk information by healthcare professionals. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered in the International Prospective Register of Systematic Reviews database (CRD42024532829). A comprehensive search of six databases yielded 17,292 records. After removing duplicates and screening for relevance, nine studies were included in the final analysis, conducted across diverse Western countries using both qualitative and quantitative designs. Results indicated a preference for healthcare-mediated communication, particularly through formal methods as letters, valued for their clarity and reliability. The role of family-mediated communication is nuanced, influenced by interpersonal relationship quality and the emotional burden of disclosing sensitive information. Ethical and legal considerations highlighted public support for overriding confidentiality in treatable conditions, while emphasizing respect for individual privacy and autonomy in untreatable conditions. This review underscores the importance of understanding public preferences to develop tailored communication strategies that balance professional involvement with respect for individual and familial dynamics. Healthcare professionals should be trained to provide empathetic, clear, and accurate information, considering the specific needs and contexts of at-risk individuals.
