Public health classics Screening criteria over the past 40 years Anne Andermann et al.

Background: With advances in genetic and genomic medicine, the optimal integration of genetic services into the health care system remains of major concern in many countries. Objectives: To review the current organisation of genetic services, mostly in Europe, North America and Australia, explore emerging service delivery models, and probe challenges inherent in the transition process. Methods: We conducted a literature review of genetics in clinical practice: testing, diagnosis, counselling, and treatment. We examined the basic structures of genetic services, examples of integrated networks, and existing professional resources. We investigated services belonging traditionally in medical genetics as well as those developed for more common diseases. Results: Multidisciplinary specialist clinics and coordinated services appeared to be key to delivering proper care in rare genetic disorders. For oncogenetics, neurogenetics and cardiogenetics, interprofessional collaboration between geneticists and other specialists seemed to be favoured. On the other hand, there was also a tendency toward the integration of genetic services directly into primary care. Among the most pressing challenges was the morphing of paediatric care into adult care. Conclusion: The coordination of activities between professionals in first-, second-, and third-line medical care is a primary objective calling for the reconfiguration of professional roles and responsibilities. This entails the forging of new relationships as well as an enhanced sharing of expertise and genetic information, including information regarding services. Barriers to overcome include the redistribution of roles, sharing of data and databases, and the lack of preparedness of non-genetics professionals and of the health care system in general.

With the ever-widening gap between what is technologically possible and services available, jurisdictions around the world are faced with complex decisions regarding the introduction and expansion of genetic screening programs. A series of literature reviews and consultations with stakeholders and experts led to the development of a decision support guide for genetic screening policy-making. This involved establishing a preliminary list of core criteria synthesized from the growing literature on genetic screening, which was then transformed through a series of consultations into a more elaborate decision guide. Although certain perennial challenges in genetic screening policy-making remain, the decision support guide aims to promote a fair and evidence-informed process that makes explicit the ethical dilemmas often inherent to such policy decisions.
