Providing Genetic Risk Information to Parents of Newboms with Sickle Cell Trait: Role of the General Practitioner in Neonatal Screening

摘要

Purpose: In 2007, the neonatal screening program in the Netherlands was expanded to include hemoglobinop-athies. Newborns with sickle cell disease (SCD), as well as SCD carriers are identified. The benefit of reporting SCD carriers includes detection of more couples at risk (both parents are carriers) who can be informed about future reproductive choices, a responsibility of their general practitioner (GP). We evaluated knowledge, ideas, and actions of GPs after reporting SCD carriers and explored and analyzed potential barriers. Methods: A questionnaire study. Results: A total of 139 GPs responded to our questionnaire (49%). Ninety GPs (90%) stated they informed parents of the test result. In only 23 cases (23%) both parents had themselves tested for hemo-globinopathies. Eighty-one GPs (64%) stated that they did not have enough clinical experience with SCD. Almost half of the GPs indicated that they did not experience any barriers in counseling patients (n=60, 48%). Conclusion: At the moment, the goal of the neonatal screening for SCD carriers has not been achieved as the majority of parents were not tested for hemoglobinopathies after disclosure of carrier status in their newborn. With GPs reporting few barriers in counseling parents and only indicating a lack of knowledge and clinical experience, more effort is required to provide better information to GPs to help facilitate their work.
