Development of newborn screening connect (NBS connect): a self-reported patient registry and its role in improvement of care for patients with inherited metabolic disorders.

BACKGROUND: Newborn Screening Connect (NBS Connect) is a web-based self-reported patient registry and resource for individuals and families affected by disorders included in the newborn screening panel. NBS Connect was launched in 2012 by Emory University after years of planning and grassroots work by professionals, consumers, and industry. Individuals with phenylketonuria (PKU), maple syrup urine disease (MSUD) or tyrosinemia (TYR) have been recruited through distribution of outreach materials, presentations at parent organization meetings and direct recruitment at clinic appointments. Participants complete online profiles generating data on diagnosis, treatment, symptoms, outcomes, barriers to care, and quality of life. Resources such as education materials, information on the latest research and clinical trials, recipes, interactive health tracking systems, and professional support tools are described. In addition, to examine the ability of NBS Connect to generate data that guides hypothesis-driven research, data pertaining to age at diagnosis, bone health, and skin conditions in individuals with PKU were assessed. The objective of this paper is to describe the development of NBS Connect and highlight its data, resources and research contributions. RESULTS: In September 2016, NBS Connect had 442 registered participants: 314 (71%) individuals with PKU, 68 (15%) with MSUD, 20 (5%) with TYR, and 40 (9%) with other disorders on the NBS panel. Age at diagnosis was less than 4 weeks in 285 (89%) of 319 respondents to this question and between 1 month and 14 years in 29 (9%) individuals. Of 216 respondents with PKU, 33 (15%) had a DXA scan in the past year. Of 217 respondents with PKU, 99 (46%) reported at least one skin condition. CONCLUSIONS: NBS Connect was built and refined with feedback from all stakeholders, including individuals with inherited metabolic disorders. Based on patient-reported data, future studies can be initiated to test hypotheses such as the relationship between PKU and skin conditions. Patient registries like NBS Connect can inform hypothesis-driven research, contributing to knowledge generation and following the current trend in moving from traditional medicine towards evidence-based practice. NBS Connect will help clinicians understand long-term outcomes of rare disorders, contributing to better patient care and quality of life.

The role of evidence analysts in creating nutrition management guidelines for inherited metabolic disorders.

RATIONALE, AIMS AND OBJECTIVES: Evidence and consensus-based guidelines for nutrition management of maple syrup urine disease (MSUD) were developed as part of a project to create nutrition guidelines for inherited metabolic disorders identified through newborn screening. The objective of this study was to describe and evaluate the role of evidence analysts in the systematic review phase of guideline development to improve quality of process and output and inform future guideline development projects. METHODS: Recruitment, training and output of evidence analysts were documented throughout the MSUD project. The role of analysts was to critically review and rate the scientific quality of published literature and abstract pertinent information using quality checklists and abstraction worksheets. A secure, web-based application was developed to standardize the process and establish permanent documentation. Analysts completed a post-project survey on perceptions of their role, training and the evidence analysis process. RESULTS: Of 23 recruits, 65% (15) completed evidence analyst training; 73% of those (11) participated in the analysis of 98 literature articles. Analysts reviewed a median of four articles (range 1-16) with median productivity of 1.1 articles per month. All analysts surveyed (n = 9) understood their role and agreed that training was adequate; 100% agreed that analyst involvement was critical in developing guidelines for MSUD. CONCLUSION: Evidence analysts played a key role in appraising and abstracting evidence to develop nutrition guidelines for MSUD. With critical improvements to the process, particularly more stringent and systematic evaluation and documentation of analyst performance related to productivity and quality, we will continue to recruit, train and support evidence analysts in evidence-based guideline development projects.
