Actionability of commercial laboratory sequencing panels for newborn screening and the importance of transparency for parental decision-making.

ABSTRACT:

Background

Newborn screening aims to identify individual patients who could benefit from early management, treatment, and/or surveillance practices. As sequencing technologies have progressed and we move into the era of precision medicine, genomic sequencing has been introduced to this area with the hopes of detecting variants related to a vastly expanded number of conditions. Though implementation of genomic sequencing for newborn screening in public health and clinical settings is limited, commercial laboratories have begun to offer genomic screening panels for neonates.

Methods

We examined genes listed on four commercial laboratory genomic screening panels for neonates and assessed their clinical actionability using an established age-based semi-quantitative metric to categorize them. We identified genes that were included on multiple panels or distinct between panels.

Results

Three hundred and nine genes appeared on one or more commercial panels: 74 (23.9%) genes were included in all four commercial panels, 45 (14.6%) were on only three panels, 76 (24.6%) were on only two panels, and 114 (36.9%) genes were listed on only one of the four panels. Eighty-two genes (26.5%) listed on one or more panels were assessed by our method to be inappropriate for newborn screening and to require additional parental decision-making. Conversely, 249 genes that we previously identified as being highly actionable were not listed on any of the four commercial laboratory genomic screening panels.

Conclusions

Commercial neonatal genomic screening panels have heterogeneous content and may contain some conditions with lower actionability than would be expected for public health newborn screening; conversely, some conditions with higher actionability may be omitted from these panels. The lack of transparency about how conditions are selected suggests a need for greater detail about panel content in order for parents to make informed decisions. The nuanced activity of gene list selection for genomic screening should be iteratively refined with evidence-based approaches to provide maximal benefit and minimal harm to newborns.

Project description:A growing number of parents delay vaccinations or are deciding not to vaccinate their children altogether. This increases the risk of contracting vaccine-preventable diseases and disrupting herd immunity, and also impairs the trust in the capacities of health care systems to protect people. Vaccine hesitancy is related to a range of both psychological and demographic determinants, such as attitudes toward vaccinations, social norms, and trust in science. Our aim is to understand those determinants in parents, because they are a special group in this issue-they act as proxy decision makers for their children, who are unable to decide for themselves. The fact that deciding to vaccinate is a socially forced choice that concerns a child's health makes vaccine-related decisions highly important and involving for parents. This high involvement might lead to parents overemphasizing the potential side effects that they know to be vaccine-related, and by amplifying those, parents are more focused on the potential outcomes of vaccine-related decisions, which can yield specific pattern of the outcome bias. We propose two related studies to investigate factors which promote vaccine hesitancy, protective factors that determine parental vaccination decisions, and outcome bias in parental vaccination intentions. We will explore demographic and psychological factors, and test parental involvement related to vaccine hesitancy using an online battery in a correlation panel design study. The second study is an experimental study, in which we will investigate the moderating role of parents' high involvement in the specific domain of vaccination decision making. We expect that higher involvement among parents, compared to non-parents, will shape the pattern of the proneness to outcome bias. The studies will be conducted across eight countries in Europe and Asia (Finland, Germany, Hong Kong, the Netherlands, Serbia, Slovenia, Spain, and the United Kingdom), rendering findings that will aid with understanding the underlying mechanisms of vaccine hesitancy and paving the way for developing interventions custom-made for parents.

Project description:BackgroundPoor patient-provider communication, among other reasons, is a notable barrier to contraceptive decision-making among Latinas. Patient-centered approaches to contraceptive counseling that optimize communication align with shared decision-making (SDM) -which is associated with satisfaction and continued contraceptive use among various populations.ObjectiveTo examine associations of patient-provider communication and importance of SDM tenets with consistent contraceptive use among a population of Latinas.Patient involvementFormative work for this study included prior qualitative and quantitative research with Latinas who expressed the importance of patient-provider communication during contraceptive counseling and therefore were instrumental in problem definition.MethodsCross-sectional surveys were administered to Latinas ages 15-29 years. Patient-provider communication, patient-reported importance of specific SDM tenets, and consistent contraception use were measured and analyzed for associations.Results103 Latinas (mean age = 21.4) participated. 33% of participants<21 years were using contraception consistently vs. 67% for those ≥ 21 (p = 0.003). Among participants ≥ 21, consistent users reported higher communication scores compared to inconsistent users and non-users (p = 0.042). For participants< 21, consistent users were more likely than inconsistent users and non-users to report that 2 SDM tenets (discussion of contraceptive preferences and avoidance of race/ethnic-based judgement) are important (p = 0.052, 0.028, respectively).DiscussionPatient-provider communication was especially important for Latinas ≥ 21 while using an SDM approach during counseling was highly valued by those<21. Patient-centered approaches to contraceptive counseling provide opportunities to optimize healthcare delivery for this vulnerable population.Practical valueResults from this research demonstrate that patient-centered communication is highly valued by Latina study participants and is an important consideration in their contraceptive counseling. Clinicians should consider employing techniques such as SDM as they seek to provide patient-centered care during contraceptive counseling for this patient population.
