This is the protocol for a review and there is no abstract. The objectives are as follows.
Primary objective: The primary objective is to assess the effectiveness of interventions to improve patient identification, access to and utilisation of genetic and genomic counselling services when compared to: No intervention;Usual or current practice; andOther active intervention.
Secondary objective: The secondary objective is to explore the resource use and costs associated with interventions aimed at improving patient identification, access to and utilisation of genetic and genomic counselling services from studies meeting the eligibility criteria. We will report on factors that may explain variation in the effectiveness of interventions aimed at improving patient identification, access to and utilisation of genetic and genomic counselling services from studies meeting the eligibility criteria. Another secondary objective is to explore how interventions which target improved patient identification, access to and utilisation of genetic and genomic counselling services affect the subsequent appropriate use of health services for the prevention or early detection of disease. It is also possible that the genetic counselling interaction itself will contribute to the possible use of preventative services.
