Parents' views on accepting, declining, and expanding newborn bloodspot screening.

INTRODUCTION: The goal of newborn bloodspot screening (NBS) is the early detection of treatable disorders in newborns to offer early intervention. Worldwide, the number of conditions screened for is expanding, which might affect public acceptance. In the Netherlands, participation is high (>99%), but little is known about how parents perceive NBS. This study assessed parents' views on accepting, declining and expanding NBS. METHODS: A total of 804 of 6051 (13%) invited parents who participated in NBS in the Netherlands during the last two weeks of December 2019, and 48 of 1162 (4%) invited parents who declined participation in NBS in 2019 and 2020, completed a questionnaire. RESULTS: The most important reason for parents to participate in NBS was to prevent health complaints, whereas the most important reason to decline NBS was parents' viewpoint on life and the belief that the heel prick would be painful for the child. Compared to NBS participants, respondents who declined NBS were more actively religious, considered alternative medicine or lifestyle more important, were less inclined to vaccinate their child for infectious diseases, and reported more doubt about NBS participation (all differences p < .001). Informed choice was lower among respondents who declined NBS (44%) compared to participants in NBS (83%, p < .001), mostly due to insufficient knowledge. Of the NBS participants, 95% were positive about NBS expansion. Most NBS participants agreed to include conditions that could unintentionally reveal a diagnosis in the mother instead of the child (86%) or a condition that may not cause symptoms until later in the child's life (84%). CONCLUSION: Most participants made an informed decision to participate in NBS and are positive about screening for more conditions. Insights into parents' views on (non-)participation and expansion of NBS can help to ensure that NBS suits the population needs while safeguarding ethical principles for screening.

Parental perspectives on retention and secondary use of neonatal dried bloodspots: a Dutch mixed methods study.

BACKGROUND: Neonatal bloodspot screening (NBS) identifies conditions to offer early intervention and minimize irreversible damage. NBS policies guide a comprehensive system including processes for storage of neonatal dried blood spots (NDBS). NDBS retention and secondary use policies have been subject of public debates internationally, suggesting that the public's perceptions of NDBS policy are not always on par with existing policies. The current study aims to provide insight in relevant factors for new parents in the Netherlands regarding retention and secondary use of NDBS. These factors can be taken into account when developing or updating NDBS policies. METHODS: A mixed methods design was used combining an online survey (n = 753), focus groups (6 groups, 37 participants), and individual in-depth interviews (n = 7). The discussed topics included: parental information, obtaining informed consent, support for retention, and support for secondary use. The study population consisted of Dutch-speaking new parents: pregnant women (≥20 weeks) and/or their partner, and parents of at least one child (≤5 years). RESULTS: New parents expressed needs for easily accessible information, adequate communication on the retention and (potential) use of NDBS, clearly described safeguards for privacy, a more active consent process, regulation for the actors conducting NDBS research, and parental involvement in decisions on secondary use. Overall, participants were positive about prolonged retention and different types of secondary use if those needs were met. CONCLUSIONS: While parental involvement is a challenge, our study is an example of gauging parent's perspectives on NDBS policy and contributes to including these perspectives in the current policy discussion on longer retention. Prolonged retention could be a feasible option in the Netherlands if several prerequisites are met. Therefore, implementation studies involving parents are needed.
