National evaluation of US newborn screening system components

Newborn screening has existed as a state-based public health service since the early 1960s. Every state and most territorial jurisdictions have comprehensive newborn screening programs in place, but in the United States a national newborn screening policy does not exist. This results in different administrative infrastructures, screening requirements, laboratory and follow-up services, medical management approaches, and related activities across the country. Federal initiatives and support have contributed to limited evaluations of various aspects of individual newborn screening programs at the national level, but funding is an issue. The national evaluation strategies have taken various forms, all with the intent of improving the screening system through review of actions taken and suggestions for future improvements. While participation in the national evaluation effort for newborn screening laboratory practices includes all US programs, and this has aided in improving quality and harmonizing protocols, other national evaluation activities have been only moderately successful. National data reporting of quality indicators for various program elements must be comprehensive and timely, and the elements must be universally accepted in order to meet the evaluation and improvement needs of the national newborn screening system. A comprehensive real time national evaluation activity will likely require additional resources and enforcement incentives. Limited federal actions through grant incentives and selected reporting requirements provide a possible means of stimulating programs to participate in national harmonization efforts.     

Design and Evaluation of a Decision Aid for Inviting Parents to Participate in a Fragile X Newborn Screening Pilot Study

The major objectives of this project were to develop and evaluate a brochure to help parents make an informed decision about participation in a fragile X newborn screening study. We used an iterative development process that drew on principles of Informed Decision Making (IDM), stakeholder input, design expertise, and expert evaluation. A simulation study with 118 women examined response to the brochure. An independent review rated the brochure high on informational content, guidance, and values. Mothers took an average of 6.5 min to read it and scored an average of 91.1 % correct on a knowledge test. Most women rated the brochure as high quality and trustworthy. When asked to make a hypothetical decision about study participation, 61.9 % would agree to screening. Structural equation modeling showed that agreement to screening and decisional confidence were associated with perceived quality and trust in the brochure. Minority and white mothers did not differ in perceptions of quality or trust. We demonstrate the application of IDM in developing a study brochure. The brochure was highly rated by experts and consumers, met high standards for IDM, and achieved stated goals in a simulation study. The IDM provides a model for consent in research disclosing complicated genetic information of uncertain value.
