ScreenPlus: A Comprehensive, Flexible, Multi-disorder Newborn Screening Program

ScreenPlus is a consented, multi-disorder pilot newborn screening program implemented in conjunction with the New York State Newborn Screening Program that provides families the option to have their newborn(s) screened for a panel of additional conditions. The study has three primary objectives: 1) define the analytic and clinical validity of multi-tiered screening assays for a flexible panel of disorders, 2) determine disease incidence in an ethnically diverse population, and 3) assess the impact of early diagnosis on health outcomes. Over a five-year period, ScreenPlus aims to screen 100,000 infants born in nine high birthrate, ethnically diverse pilot hospitals in New York for a flexible panel of 14 rare genetic disorders. This study will also involve an evaluation of the Ethical, Legal and Social issues pertaining to NBS for complex disorders, which will be done via online surveys that will be directed towards ScreenPlus parents who opt to participate and qualitative interviews with families of infants who are identified through ScreenPlus.

Soon after birth, all babies born in the United States have a newborn screening (NBS) test to check for certain medical conditions. All babies are screened, even if they appear healthy, because most of these conditions have no obvious physical findings in a newborn and might otherwise be diagnosed only after the development of serious problems, such as brain damage, organ damage, or death. In fact, NBS has been an integral part of preventable health care for over five decades, ever since the discovery that phenylketonuria is an easily diagnosed, preventable cause of intellectual disability.

Over the past two decades, there have been dramatic advances in screening technology, with a resulting increase in the number and complexity of disorders on NBS panels. This enhanced ability to screen brings questions about what types of disorders are appropriate for NBS. To that end, the Advisory Committee on Heritable Disorders in Newborns and Children (ACHDNC) was established in 2003 to make evidence-based recommendations at the national level regarding the suitability of various disorders for NBS. At present, the Recommended Uniform Screening Panel, or the RUSP, includes 35 core disorders. The RUSP nomination process uses information about disease incidence and severity, natural history, benefits of early detection, safety and efficacy of treatment, analytic and clinical validity of the screening tests, as well as consideration of potential harms associated with screening and public health impact to determine whether a particular disorder is appropriate for NBS. However, there are many disorders for which this data is insufficient or missing. There are other disorders that challenge traditional NBS criteria by having predominantly later-onset phenotypes, poorly defined natural history, or unclear treatment outcomes. As these potentially life-threatening disorders might benefit from early detection, gathering and analyzing this data is both critical and timely. Accordingly, there is a great deal of interest in pilot NBS studies as a means to gather objective evidence about whether a disorder is appropriate for widespread screening.

ScreenPlus is a comprehensive, fluid, pilot NBS program that will screen 100,000 consented infants for specific disorders that are under consideration for universal NBS. This study will generate critical data about the validity of testing for these candidate disorders and provide estimates of disease incidence in a large, ethnically diverse population. The investigators will evaluate different consent and engagement models, including direct, in-person interaction and the use of a novel E-Consent framework to educate parents about pilot NBS. The investigators will also collect nuanced information about the ethical implications of NBS, by conducting qualitative interviews with parents of children who have received a positive or uncertain NBS result. Parents who are eligible to participate in ScreenPlus will also have the opportunity to complete a flexible set of surveys of parent opinions about expanded NBS, research using dried blood spots, and other relevant topics. Furthermore, newborns who screen positive will be followed by a ScreenPlus physician. Through thoughtful collaboration with disease experts, the investigators will help systematically collect disease specific measures through detailed long-term follow-up which will enable us to critically evaluate how affected children identified through ScreenPlus are faring, allowing objective assessment of the impact early diagnosis has on outcome.

The investigators will share this important data with the NBS community, including the ACHDNC, to help inform objective decision-making about widespread screening recommendations. The ScreenPlus panel is fluid and disorders may be added/removed as disorders satisfy the study inclusion criteria or are added to the RUSP and/or the New York State routine NBS panel. Additionally, recognizing that the NIH, advocacy groups, academics, and private industry all share a desire for clean, consented pilot NBS data, the investigators created a unique financial infrastructure. This investigator-driven arrangement permits all stakeholders to obtain aggregate data of interest in a mutually beneficial and cost-effective manner. ScreenPlus is guided by Scientific and Community Advisory Boards, who are comprised of rare disease experts, biochemistry specialists, physicians, bioethicists, and patient advocates. Overall, the investigators anticipate that ScreenPlus will become the premier consented pilot NBS program in the United States.

In sum, ScreenPlus will provide critical data about the appropriateness of NBS for candidate disorders, the feasibility and effectiveness of consented screening models, and parent informational needs and preferences as they relate to NBS for complex disorders.
