Recommendations for effective newborn screening communication: results of focus groups with parents, providers, and experts

Stakeholder attitudes towards the role and application of informed consent for newborn bloodspot screening: a study protocol

INTRODUCTION

Newborn bloodspot screening (NBS) involves testing a small sample of blood taken from the heel of the newborn for a number of serious and life-limiting conditions. In Canada, newborn screening programmes fall under provincial and territorial jurisdiction with no federal coordination. To date, we know very little about the underlying beliefs around different consent practices or how terminology is interpreted by different individuals. Differences in attitudes may have important healthcare consequences. This study will provide empirical data comparing stakeholder opinions on their understanding of consent-related terminology, the perceived applicability of different consent approaches to newborn screening, and the requirements of these different approaches.

METHODS AND ANALYSIS

Parents, healthcare professionals and policymakers will be recruited in the provinces of Ontario and Newfoundland and Labrador. Parents will be identified through records held by each provincial screening programme. Healthcare professionals will be purposively sampled on the basis of engagement with newborn screening. Within each province we will identify policymakers who have policy analysis or advisory responsibilities relating to NBS. Data collection will be by qualitative interviews. We will conduct 20 interviews with parents of young children, 10 interviews with key healthcare professionals across the range of appropriate specialties and 10 with policymakers at each site (40 per site, total, N=80). The examination of the transcripts will follow a thematic analysis approach. Recruitment started in June 2014 and is expected to be complete by June 2015.

ETHICS AND DISSEMINATION

This study received ethics approval from the Ottawa Health Science Network Research Ethics Board, the Children's Hospital of Eastern Ontario Research Ethics Board (both Ontario), and the Health Research Ethics Authority (Newfoundland and Labrador).

RESULTS

These will be reported in peer-reviewed publications and conference presentations. The results will have specific application to the development of parent education materials for newborn screening.

Education and parental involvement in decision-making about newborn screening: understanding goals to clarify content

A challenge in designing effective education for parents about newborn screening (NBS) has been uncertainty about appropriate content. Arguing that the goals of education may be usefully tied to parental decision-making, we sought to: (1) explore how different ways of implementing NBS differ in their approaches to parental engagement in decision-making; (2) map the potential goals of education onto these "implementation models"; and (3) consider the content that may be needed to support these goals. The resulting conceptual framework supports the availability of comprehensive information about NBS for parents, irrespective of the model of implementation. This is largely because we argue that meeting parental expectations and preferences for communication is an important goal regardless of whether or notparents are actively involved in making a decision. Our analysis supports a flexible approach, in which some educational messages are emphasized as important for all parents to understand while others are made available depending on parents' preferences. We have begun to define the content of NBS education for parents needed to support specific goals. Further research and discussion is important to determine the most appropriate strategies for delivering the tailored approach to education that emerged from our analysis.

What parents want to know about the storage and use of residual newborn bloodspots

Many state newborn screening programs retain residual newborn screening bloodspots for a variety of purposes including quality assurance, biomedical research, and forensic applications. This project was designed to determine the information that prospective parents want to know about this practice. Eleven focus groups were conducted in four states. Pregnant women and their partners and parents of young children (N = 128) were recruited from the general public. Focus group participants viewed two educational movies on newborn screening and DBS retention and use. Transcripts were analyzed with qualitative methods and the results were synthesized to identify key information items. We identified 14 categories of information from the focus groups that were synthesized into seven items prospective parents want to know about residual DBS. The items included details about storage, potential uses, risks and burdens, safeguards, anonymity, return of results, and parental choice. For those state programs that retain residual dried bloodspots, inclusion of the seven things parents want to know about residual dried bloodspots in educational materials may improve parental understanding, trust, and acceptance of the retention and use of stored bloodspots.

Benefits and burdens of newborn screening: public understanding and decision-making

In this article we review the literature regarding the public understanding of the potential benefits and burdens of expanded newborn bloodspot screening. We draw attention to broadened notions of benefit that go beyond early identification of asymptomatic individuals and interventions to reduce morbidity or mortality, and include benefits gained by families through knowledge that may facilitate life choices, as well as gains generated by avoiding diagnostic delays. We also reflect on burdens such as increasing false-positive results and parental anxiety, together with risks of overdiagnosis when the natural history of a condition is poorly understood. We conclude that expanded notions of benefit and burden bring with them implications for parental consent and confidentiality and the secondary use of bloodspots.

Parents' responses to receiving sickle cell or cystic fibrosis carrier results for their child following newborn screening

Universal newborn screening for sickle cell disorders and cystic fibrosis aims to enable the early identification and treatment of affected babies. Screening can also identify infants who are healthy carriers, with carrier results being the commonest outcome for parents and professionals to discuss in practice. However it is unclear what the effect will be on parents on being informed of their baby's carrier result. Semi-structured face-to-face interviews were conducted with a purposeful sample of 67 family members (49 mothers, 16 fathers, 2 grandparents) of 51 infants identified by universal newborn screening as carriers of cystic fibrosis (n=27) and sickle cell (n=24), across all health regions in England. Data were analysed by thematic analysis with subsequent respondent validation. Untoward anxiety or distress among parents appeared influenced by how results were conveyed, rather than the carrier result per se. Parents who had more prior awareness of carrier status or the possibility of a carrier result assimilated the information more readily. Being left in an information vacuum while awaiting results, or before seeing a professional, led some parents to fear that their child had a serious health condition. Parental distress and anxiety appeared mostly transient, subsiding with understanding of carrier status and communication with a professional. Parents regarded carrier results as valuable information and sought to share this with their families and to inform their children in the future. However parents needed greater support after communication of results in considering and accessing cascade testing, and negotiating further communication within their families.

Legislation impacting audiology and the provision of audiological services: a review of legislation across the United States

PURPOSE

The purpose of this review was to investigate the legislation about the provision of audiology services. Specifically, the goal of the review was to investigate the similarities and differences in legislation regarding the identification of, and audiology services provided to, children with hearing loss.

METHOD

A systematic review was conducted to collect state-specific legislation regarding the audiology licensure requirements, requirements about the identification and management of children with hearing loss, and insurance coverage regulations. Compiled data were analyzed for similarities and differences between state regulations and legislature.

RESULTS

All states require audiologists to hold licensure; however, many differences exist between the requirements of acquiring and maintaining the license. Some states regulate the identification and management of children with hearing loss, whereas others do not. Additionally, states differ in their regulation of services provided to children with hearing loss, who can provide these services, and what is covered by insurance.

CONCLUSION

It is critical for audiologists to understand the requirements of their state in the provision of audiology services. Specifically, it is important for audiologists to understand how the laws may impact the services they provide to children with hearing loss.

Considering consent: a structural equation modelling analysis of factors influencing decisional quality when accepting newborn screening

INTRODUCTION

Newborn bloodspot screening (NBS) programs generate an ethical tension between promoting the uptake of effective public health measures and facilitating informed consent from individuals.

AIM

To explore the factors that affect parental perceptions of decision quality when accepting NBS METHODS: Survey of parents with children screened in 2008 (n = 154, 32% response rate). Questions were based on previous research and existing measures. The primary outcome was decision quality. Predictors were latent constructs of Attitudes to medicine, Perceived knowledge, Attitudes to screening, and Perceived choice. Responses were analysed using structural equation modelling.

RESULTS

Increases in perceived choice and positive attitudes towards screening improved decision quality. Perceived knowledge had a significant and positive relationship with attitudes to screening (0.375, p < 0.01) as did perceived choice on perceived knowledge (0.806, p < 0.01). Attitudes to screening were also significantly influenced by attitudes to medicine, although less so than the effect of perceived knowledge. The model had good fit on all indices (χ(2) = 61.396, df = 48, p = 0.093; CFI = 0.979; RMSEA = 0.043).

CONCLUSIONS

Our results implicate the presentation of screening as a key determinant of decision quality both in terms of the immediate information regarding the potential benefits and risks, but also the way in which consent processes are managed. If we want to better understand parent decision-making we need to go beyond analyses of information content, or parental recall of this, but consider the context in which screening is provided.

Informing children of their newborn screening carrier result for sickle cell or cystic fibrosis: qualitative study of parents' intentions, views and support needs

Newborn screening for cystic fibrosis and sickle cell disease enables the early identification and treatment of affected children, prolonging and enhancing their quality of life. Screening, however, also identifies carriers. There are minimal or no health concerns for carriers. There are, however, potential implications when carriers reach reproductive age, and thus research attention has been given to how best to convey information about these implications in a meaningful, balanced way which does not raise undue anxieties. Most research focuses on the communication from health professional to parent, yet ultimately this information is of greatest significance to the child. This study examines parents' intentions to inform their child of newborn screening carrier results. Semi-structured interviews with 67 family members explored their intentions to inform the child, and related views and support needs. Parents almost unanimously indicated they planned to inform the child themselves. Health professionals were expected, however, to provide guidance on this process either to parents through advice and provision of written materials, or directly to the child. Although parents initially stated that they would convey the result once their child had developed the ability to understand the information, many appeared to focus on discrete life events linked to informed reproductive decision making. The results highlight ways in which health care providers may assist parents, including providing written material suitable for intergenerational communication and ensuring that cascade screening is accessible for those seeking it. Priorities for further research are identified in light of the results.

Residual newborn screening samples for research: parental information needs for decision-making

PURPOSE

The purpose of this research was to identify what types of information expectant parents want to make a decision about the use of their babies' residual dried blood specimens for research.

DESIGN AND METHODS

Three focus groups were conducted with pregnant women and their partners and one focus group with prenatal healthcare providers and educators.

RESULTS

Eleven categories of information needs were identified within each focus group.

PRACTICE IMPLICATIONS

Providing sufficient information for parents to make informed choices will be essential to future research with residual dried blood specimens and to maintain public trust with the growing applications of this important public health program.

Technical report: Ethical and policy issues in genetic testing and screening of children

The genetic testing and genetic screening of children are commonplace. Decisions about whether to offer genetic testing and screening should be driven by the best interest of the child. The growing literature on the psychosocial and clinical effects of such testing and screening can help inform best practices. This technical report provides ethical justification and empirical data in support of the proposed policy recommendations regarding such practices in a myriad of settings.

Retention and research use of residual newborn screening bloodspots

The storage and use of residual newborn screening dried blood specimens has generated significant controversy in the past 5 years, primarily because of public concerns over the lack of parental knowledge and consent for these activities. State policies addressing the management of these specimens vary widely, and there is currently little guidance to aid new state policy development to address the concerns of program professionals, investigators, and the general public. This article offers guidance for state policy based on multiple sources of data, including public attitudes, professional statements, state experience, and an analysis of the ethical, social, legal, and biomedical issues from a multidisciplinary group of scholars. This guidance will be useful for state programs that seek to develop policies that are informed by a contemporary analysis of the key ethical, legal, and social aspects of this practice. This article represents the work of the authors and does not represent American Academy of Pediatrics policy.

Lessons that newborn screening in the USA can teach us about biobanking and large-scale genetic studies

The intent in establishing newborn screening programs was not to create and sustain a large-scale genetic biobanks. Instead, newborn screening programs were designed as a public health program. As such, they have successfully screened millions of asymptomatic newborns for disease that, undiagnosed and untreated, would cause disability or death. However, historical decisions on retention of residual samples and technological innovation have forced these programs and their proponents to confront the prospect of biobanking and the conduct of large-scale genetic studies. We suggest that the challenges facing newborn screening can provide important lessons for other biobanking and large-scale genetic testing endeavors.

Informed choice for newborn blood spot screening in the United Kingdom: a survey of parental perceptions

OBJECTIVE

In the United Kingdom, newborn blood spot screening proceeds on the basis of consent based on an informed choice. However, little is known about parent experiences of this process. This study was intended to explore parents' understanding of newborn screening and their experience of the consent process using a structured survey.

METHODS

A mail survey exploring key components of consent was sent to parents whose children had been screened in the year before the study. A descriptive analysis of responses together with logistic regression was performed to identify variables that predicted parental likelihood to agree that they had made an informed choice to screening.

RESULTS

Most parents indicated they understood why the heel prick was done, but only a third understood how conditions would be dealt with if found. Almost a third of parents reported that they did not feel they had a choice to decline screening, yet >70% felt they had made an informed choice. Logistic regression indicated previous children, understanding why the heel prick was done, having time to make a decision, and feeling they had a choice were significant predictors of feeling an informed choice had been made.

CONCLUSIONS

The findings support previous studies that screening may be seen as a fait accompli. Analyses indicated that allowing time to make a decision (eg, by providing information during pregnancy, emphasizing the decision-making aspect, and clearly articulating the reasons behind screening) may help parents feel that they have made an informed choice.

Newborn screening and the obstetrician

Newborn screening is the largest genetic screening program in the United States with approximately four million newborns screened yearly. It has been available and in continuous development for more than 50 years. Each state manages, funds, and maintains its own individual program, which encompasses newborn screening as well as the diagnosis and coordination of care for affected infants and children. The ideal disorder for screening is one in which newborn intervention prevents later disabilities or death for infants who may appear normal at birth. There are 31 core conditions that are currently recommended for incorporation into state screening programs. To obtain a sample, several drops of blood are collected from the newborn's heel and applied to filter paper. Although testing for core disorders is fairly standardized, more extensive screening varies by state and the rigorous evaluation of new disorders for inclusion in state screening panels is ongoing. As genomic medicine becomes more accessible, screening newborns for chronic diseases that may affect their long-term health will need to be addressed as well as the use of the residual blood spots for research. Obstetric providers should, at some time during pregnancy, review the basic process of newborn screening with parents to prepare them for this testing in the neonatal period. This information can be reviewed as it best suits incorporation in an individual's practice; verbal discussion and the distribution of written materials with resources for further information are encouraged.

Factors associated with knowledge of and satisfaction with newborn screening education: a survey of mothers

Purpose:

Effective parental education about newborn blood-spot screening may facilitate prompt follow-up, reduce psychosocial harms, and promote trust in screening programs. However, little is known about the aspects of education delivery and content that are of most importance for fostering understanding and meeting parental expectations. We aimed to identify elements of newborn blood-spot screening education and their associations with mothers' knowledge and satisfaction levels.

Methods:

We conducted a survey (by mail) of 1,712 mothers who were residing in Ontario, Canada, and whose infants had recently undergone newborn blood-spot screening.

Results:

We received 750 completed questionnaires (response rate 47%). Factors associated with respondents' higher knowledge of newborn blood-spot screening were higher level of education (odds ratio = 2.79), English being spoken at home (odds ratio = 1.96), receiving an information sheet at the time of newborn blood-spot screening (odds ratio = 1.57), and receiving information about how to interpret the results (odds ratio = 2.65). Factors associated with being satisfied were: receiving information prenatally (odds ratio = 2.35), from a health-care professional (odds ratio = 4.54), or from an information sheet at the time of newborn blood-spot screening (odds ratio = 1.72); and receiving messages about the purpose of screening (odds ratio = 3.78), the communication process (odds ratio = 2.57), the interpretation of the results (odds ratio = 4.19), and sample-handling methods (odds ratio = 3.13).

Conclusion:

Promoting mothers' understanding and meeting their expectations with respect to education about newborn blood-spot screening may require greater engagement with prenatal providers. It also calls for a greater emphasis on communicating with mothers about how blood samples are handled and about the meaning of the test results.

Use of social support during communication about sickle cell carrier status

OBJECTIVE

To examine the use of social support behaviors by primary care providers during delivery of positive newborn screening results for Sickle Cell Anemia carrier status.

METHODS

Transcripts from 125 primary care providers who conveyed Sickle Cell Anemia carrier status to standardized parents were content analyzed using categories derived from Cutrona and Suhr's social support taxonomy. Frequencies and cross-tabulation matrices were calculated to study providers' social support utilization.

RESULTS

Results showed most primary care providers (80%) incorporate social support behaviors into delivery of Sickle Cell Anemia carrier results and most frequently employed social network (61.6%) and informational support (38.4%) behaviors. Providers used tangible aid (8%), esteem (1.6%), and emotional support (9.6%) behaviors less frequently.

CONCLUSION

Cutrona and Suhr's taxonomy may be a useful tool for assessing supportive communication during the delivery of Sickle Cell Anemia carrier status and could be incorporated into population scale assessments of communication quality assurance.

PRACTICE IMPLICATIONS

Primary care providers may need training in how to adapt supportive behaviors to parents' needs during communication of Sickle Cell Anemia carrier status. They also may benefit from specific training about how to use esteem and emotional support.

Newborn screening for metabolic disorders: parental perceptions of the initial communication of results

Positive newborn screening (NBS) results cause significant parental distress, but little is known about how parents find out about children's screening results and what they are told. This qualitative, exploratory study reports on parents' perceptions of the initial communication of NBS results. Participants included the parents of 75 infants referred to a metabolic clinic in California over a 3-year period (2007-2010). Parents provided information about the initial communication of NBS results during audiotaped clinical encounters and open-ended interviews. Transcripts were analyzed inductively using thematic coding. Responses fell into 3 primary themes: sources of news delivery, providing information, and mitigation strategies. The findings suggest that health care providers have access to a range of communicative resources to buffer the impact of positive screening results that may be mobilized in future interventions. Recommendations for improving the communication process and future research directions are discussed.

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.

The impact of false-positive newborn screening results on families: a qualitative study

PURPOSE

Newborn screening leads to improved treatment and disease outcomes, but false-positive newborn screening results may cause distress for parents. The purpose of this study was to describe the experiences of families who receive a false-positive newborn screening result in an attempt to discover ways to help improve the newborn screening communication process for families.

METHODS

This was a qualitative study using two methods of data collection: in-depth, semistructured interviews and focus groups. Participants (N = 27) were parents whose children (ages 6-16 months) underwent follow-up testing after newborn screening and whose follow-up test results indicated that the newborn screening result was a false-positive.

RESULTS

Our analysis found that parents who have a false-positive newborn screening result experience five distinct stages. Most parents did not report long-term negative impacts of the experience, but some experienced some residual worry. Participants described effective provider communication as key in mitigating stress. Some parents identified the experience as leading to positive outcomes.

CONCLUSION

Identifying best practices for communication between the health care providers and parents is an essential component in improving the newborn screening process. Further research is needed to discover best practices for communication to minimize potential harm and maximize the benefits of newborn screening.

Ethical issues with newborn screening in the genomics era

Continued technological advances have made the prospect of routine whole-genome sequencing (WGS) imminent. To date, much of the discussion about WGS has focused on its application and use in clinical medicine. Relatively little attention has been paid to the potential integration of WGS into newborn screening programs. Given the structure and scope of these programs, it is possible that the early applications of WGS will occur in state-run newborn screening programs. Assessment of the pressing ethical issues currently facing the newborn screening community will provide insight into the challenges that lie ahead in the genomics era.

Parental information use in the context of newborn bloodspot screening. An exploratory mixed methods study

The aim of this study was to investigate how parents select and use information sources when considering newborn bloodspot screening. Mixed methods approach using semi-structured interviews (n = 18) and a self-completion postal questionnaire (n = 154) conducted with parents of children who had undergone newborn bloodspot screening. Qualitative data was assessed using a thematic analysis approach with quantitative data analyzed using multinomial logistic regression. Parents used a limited range of information. In the UK, maternity services are largely delivered by the midwife and the healthcare practitioner was the main information source for parents, with only half of parents using official health service leaflets. Barriers included the provision of information post-natally and with other non-healthcare materials. Neither number of children, age group, education level, nor income were significantly associated with the number of information sources used. Nor were they associated with the information source indicated as most important. The midwife is well placed to act as a gatekeeper for parents seeking information about newborn bloodspot screening. Even when additional sources are used, the midwife remains a prominent source of information. Furthermore, the use of written materials is dependent upon appropriate delivery and consequently delivery is essential to information use.

Public attitudes regarding the use of residual newborn screening specimens for research

BACKGROUND AND OBJECTIVES

Many state newborn screening (NBS) programs retain residual NBS bloodspots after the completion of screening. Potential uses for residual specimens include laboratory quality assurance, biomedical research, and, rarely, forensic applications. Our objective was to evaluate public opinion about the policies and practices relevant to the retention and use of residual bloodspots for biomedical research.

METHODS

A total of 3855 respondents were recruited using 3 methods: focus groups (n = 157), paper or telephone surveys (n = 1418), and a Knowledge Networks panel (n = 2280). Some participants (n = 1769) viewed a 22-minute movie about the retention and use of residual specimens while other participants were provided only written information about this practice. All participants were surveyed using a 38-item questionnaire.

RESULTS

A diverse set of participants was recruited. Respondents were very supportive of NBS in general and accepting of the use of residual bloodspots for important research activities. Respondents were evenly divided on the acceptability of NBS without parental permission, but the majority of respondents supported the use of an "opt-in" process for parental permission for residual bloodspot retention and use. Viewing the educational movie was associated with greater support for bloodspot retention and use.

CONCLUSIONS

Our results show that the general public surveyed here was supportive of NBS and residual sample retention and research use. However, there was a clear preference for an informed permission process for parents regarding these activities. Education about NBS was associated with a higher level of support and may be important to maintain public trust in these important programs.

Caregiver opinions about fragile X population screening

PURPOSE

We sought to determine caregiver perceptions about population screening for fragile X and to examine factors potentially associated with support for screening.

METHODS

We asked 1,099 caregivers of a child with fragile X syndrome or a fragile X carrier to rate whether free, voluntary screening should be offered preconception, prenatally, neonatally, or when problems occur. Caregivers chose a preferred time for screening, reported whether screening would affect parent-child bonding, indicated preferences for carrier detection, and gave reasons for their choices.

RESULTS

Caregivers endorsed all forms of screening, but prenatal screening was less strongly endorsed than preconception or postnatal screening. Most (79%) preferred preconception carrier testing, allowing more options when making reproductive decisions. Most thought that screening should also disclose carrier status and believed a positive screen would not negatively affect parent-child bonding. Maternal education, caregiver depression, family impact, and severity of disability were not associated with screening opinions, but parents who only had carrier children were less likely to endorse prenatal screening.

CONCLUSION

Caregivers of children with fragile X widely endorse screening. However, because different parents will make different choices, screening may need to be offered at multiple times with careful consideration of consent and informed decision-making.

Newborn screening education on the internet: a content analysis of North American newborn screening program websites

The Internet is a potentially important medium for communication about public health programs including newborn screening. This study explores whether the information available on official newborn screening program websites is consistent with existing guidelines regarding educational content for parents. We conducted a systematic search of the public websites of newborn screening programs in the US and Canada, identifying web pages and downloadable brochures that contained educational information. Two researchers independently reviewed all documents to determine the extent to which they included 14 key recommended educational messages. We identified 85 documents containing educational information on 46 US and 6 Canadian newborn screening program websites. The documents contained from 1 to 14 of the recommended messages. The majority of identified materials emphasized the importance and benefits of screening. The differences between US and Canadian materials were related to the importance of parental involvement in follow-up and issues of consent and storage of blood spots. Our findings are consistent with studies of non-web-based newborn screening education materials. The results emphasize the need for further evaluation of newborn screening education, including internet-based resources, particularly in terms of the impact of particular messages on parental attitudes and behaviors.

Parental views on informed consent for expanded newborn screening

BACKGROUND

An increasing array of rare inherited conditions can be detected as part of the universal newborn screening programme. The introduction and evaluation of these service developments require consideration of the ethical issues involved and appropriate mechanisms for informing parents and gaining consent if required. Exploration of parental views is needed to inform the debate and specifically consider whether more flexible protocols are needed to fit with the public perception of new developments in this context.

OBJECTIVE

This study has been undertaken to explore perceptions and attitudes of parents and future parents to an expanded newborn screening programme in the United Kingdom and the necessary information provision and consent processes.

DESIGN AND PARTICIPANTS

A mixed methods study involving focus groups (n = 29) and a web-survey (n = 142) undertaken with parents and future parents.

RESULTS AND CONCLUSIONS

Parents want guaranteed information provision with clear decision-making powers and an awareness of the choices available to them. The difference between existing screening provision and expanded screening was not considered to be significant enough by participants to warrant formal written, informed consent for expanded screening. It is argued that the ethical review processes need to be more flexible towards the provision of information and consent processes for service developments in newborn screening.

Parents' experiences of expanded newborn screening evaluations

OBJECTIVE

Abnormal results of newborn screening for common metabolic diseases are known to create substantial distress for parents. We explored parents' perceptions during diagnostic evaluations for newer disorders that are less well understood.

METHODS

Thirty families completed 48 open-ended interviews before and/or after parents received confirmatory test results for their infants. Qualitative content analysis was used to analyze the data.

RESULTS

Parents were shocked by the notification of the abnormal test result. Their urgent and often frustrating searches for information dominated the early phase of the screening process. Treatment center personnel were mainly informative and reassuring, but waiting for results exacerbated parents' distress. Equivocal results from diagnostic testing created uncertainties for parents regarding their infants' long-term health. After counseling, some parents reported inaccurate ideas about the disorders despite exposure to large amounts of information. Regardless of the challenges and anxieties of the evaluation, nearly every parent thought newborn screening was an important program for infant health.

CONCLUSIONS

The evaluation of a newborn for an abnormal screening result was highly stressful for parents. To help reduce parents' distress, improvements in communications and clinical services are needed. Recommendations of useful Internet sites and discussions of this information may benefit parents. Tailoring counseling to meet the needs of culturally and educationally diverse families is needed. Families and infants with equivocal results are a new group of patients who merit comprehensive clinical follow-up.

Genetic screening

Current approaches to genetic screening include newborn screening to identify infants who would benefit from early treatment, reproductive genetic screening to assist reproductive decision making, and family history assessment to identify individuals who would benefit from additional prevention measures. Although the traditional goal of screening is to identify early disease or risk in order to implement preventive therapy, genetic screening has always included an atypical element-information relevant to reproductive decisions. New technologies offer increasingly comprehensive identification of genetic conditions and susceptibilities. Tests based on these technologies are generating a different approach to screening that seeks to inform individuals about all of their genetic traits and susceptibilities for purposes that incorporate rapid diagnosis, family planning, and expediting of research, as well as the traditional screening goal of improving prevention. Use of these tests in population screening will increase the challenges already encountered in genetic screening programs, including false-positive and ambiguous test results, overdiagnosis, and incidental findings. Whether this approach is desirable requires further empiric research, but it also requires careful deliberation on the part of all concerned, including genomic researchers, clinicians, public health officials, health care payers, and especially those who will be the recipients of this novel screening approach.

Parental understanding of newborn screening for cystic fibrosis after a negative sweat-test

BACKGROUND

Newborn screening for cystic fibrosis (CF) in Illinois uses an immunoreactive trypsinogen/DNA methodology; most false-positive results identify unaffected carriers.

METHODS

Parents whose child received a negative result from the sweat test after a positive newborn screening for CF were surveyed ≥ 6 weeks later by telephone. All parents received genetic counseling while waiting for the sweat-test results.

RESULTS

A total of 90 parents participated. Overall knowledge of CF was high (78%), but the ability to understand the CF screening results was mixed. Although 94% of the parents understood that their child did not have CF, only 79% (62 of 78) of participants whose child had a mutation knew their child was definitely a carrier, and only 1 of 12 parents whose child had no mutation understood that the child may be a carrier. Respondents stated that most relatives were not interested in genetic testing. Both parents had been tested in only 13 couples. Fewer than half (36 of 77 [47%]) of the untested couples expressed interest in genetic testing. Although most participants were satisfied with the process, parents expressed frustration because of the lack of prospective newborn screening discussions by prenatal and pediatric providers and lack of knowledge and sensitivity by those who initially notified them of the abnormal newborn screening results. Speaking to a genetic counselor when scheduling the sweat test decreased anxiety for many parents (53 of 73 [73%] were "very worried" at notification versus 18 of 73 [25%] after scheduling; P < .001).

CONCLUSIONS

Parental knowledge about CF is high, but confusion about the child's carrier status and the concept of residual risk persist despite genetic counseling. Relatives express low interest in carrier testing.

Newborn screening: ethical, legal, and social implications

Newborn dried blood spot screening (NBS) is a core public health service and is the largest application of genetic testing in the United States. NBS is conducted by state public health departments to identify infants with certain genetic, metabolic, and endocrine disorders. Screening is performed in the first few days of life through blood testing. Several drops of blood are taken from the baby's heel and placed on a filter paper card. The dried blood, on the filter cards, is sent from the newborn nursery to the state health department laboratory, or a commercial partner, where the blood is analyzed. Scientific and technological advances have lead to a significant expansion in the number of tests-from an average of 6 to more than 50--and there is a national trend to further expand the NBS program. This rapid expansion has created significant ethical, legal, and social challenges for the health care system and opportunity for scholarly inquiry to address these issues. The purpose of this chapter is to provide an overview of the NBS programs and to provide an in-depth examination of two significant concerns raised from expanded newborn screening, specifically false-positives and lack of information for parents. Implications for nursing research in managing these ethical dilemmas are discussed.

Parental attitudes toward ethical and social issues surrounding the expansion of newborn screening using new technologies

AIMS

This study assessed parent knowledge of newborn screening (NBS) and parent attitudes toward NBS for untreatable conditions, NBS for late-onset disorders and informed consent in NBS.

METHODS

Seventeen qualitative focus groups were held in Alaska, California, Hawaii, and Washington with mothers of children 10 years old or younger.

RESULTS

Most participants did not recall receiving information about NBS, and all wanted this information prenatally. In addition, most felt that the current system of 'informed dissent' was adequate, provided they were told about NBS prior to delivery. All women supported NBS for conditions that occur in infancy without a proven treatment. However, they disagreed about NBS for disorders that manifest in late childhood or adulthood.

CONCLUSIONS

The results show a general consensus among the focus group participants about issues that cause dissent among public health and health care professionals. Parent attitudes differ from those of many professional communities with regard to timing of NBS education, informed consent, NBS for disorders that lack an effective treatment, and predictive testing of children for late-onset disorders. The results highlight the need to further research parent opinions about expanded NBS using new technologies and to include parents in the development of NBS policies.

Newborn Screening System Performance Evaluation Assessment Scheme (PEAS)

Newborn screening (NBS) reaches approximately all of the 4 million newborns in the United States each year and has been effective in significantly reducing the morbidity and mortality that results from certain congenital conditions. The comprehensive NBS system can be divided into preanalytic (education and screening), analytic (laboratory testing), and postanalytic (reporting, short-term follow-up/tracking, diagnosis, treatment/management, ancillary services, and outcome evaluation) activities. To monitor and improve the screening system, there has been increasing emphasis on evaluation models. Federal sponsorship of a model performance evaluation and assessment scheme (PEAS) has resulted in a comprehensive listing of quality indicators for system self-assessment. We review the PEAS evolution process in an effort to illustrate the necessary infrastructure considerations in a well-functioning NBS system. Readers are encouraged to identify their role in the system and to interact appropriately at the local level. The comprehensive PEAS indicator list is provided as an Appendix.

Policy issues and stakeholder concerns regarding the storage and use of residual newborn dried blood samples for research

Newborn screening is an important public health programs in the United States. Over 4 million infants are screened each year for a number of conditions. There is a growing need for more explicit state policies governing the storage and research use of residual newborn samples. This paper provides an overview of newborn screening and issues related to policies of residual newborn samples as well as attitudes and opinions from stakeholders. Three groups (n = 21) were conducted with stakeholders: an African American group, a Pediatrician group and a Mothers of young children group. Despite the differences between these groups, consistent themes emerged from all groups that may be relevant for policy development governing the storage and use of residual newborn samples. The data from this exploratory study suggest that future policy developments with the newborn screening program warrant further public input on these topics.

Maternal knowledge and attitudes about newborn screening for sickle cell disease and cystic fibrosis

Illinois introduced mandatory newborn screening (NBS) for sickle cell disease (SCD) in 1989 and for cystic fibrosis (CF) in 2008. We examined maternal understanding of NBS for SCD and CF, and their knowledge of the genetics, symptoms, and treatments of both conditions. Our methods consisted of conducting interviews of inpatient post-partum women (>18 years and English speaking). Our results showed that of the 388 eligible participants, 34 self-identified as sickle cell carriers, 1 with SCD and 1 as a CF carrier. Almost 3/4 were African American (282/387). Although all but 5 women had prenatal care, only 35% (133/378) recalled their prenatal care provider mentioning NBS, and only 56% (217/388) of participants recalled nursery staff mentioning NBS. There was more self-reported familiarity with SCD (3.32/5) than CF (1.97/5, P < 0.001). Over 2/3 (260/388) of participants could not answer CF knowledge questions because they had never heard of CF. Among those who had heard of the conditions, mean knowledge scores were 66% for SCD (n = 372) and 63% for CF (n = 128). Bivariate analysis identified education, age, race, marital status, and insurance status as statistically significant. After linear regression education remained significant for both conditions. We conclude that in a sample of predominantly African American post-partum women, we found poor understanding of NBS, greater familiarity with SCD, and significant knowledge gaps for both SCD and CF. There are many missed educational opportunities for educating parents about NBS and specific conditions included in NBS panels in both the obstetric clinics and the nursery.

Parental understanding of infant health information: health literacy, numeracy, and the Parental Health Literacy Activities Test (PHLAT)

OBJECTIVE

To assess parental health literacy and numeracy skills in understanding instructions for caring for young children, and to develop and validate a new parental health literacy scale, the Parental Health Literacy Activities Test (PHLAT).

METHODS

Caregivers of infants (age <13 months) were recruited in a cross-sectional study at pediatric clinics at 3 academic medical centers. Literacy and numeracy skills were assessed with previously validated instruments. Parental health literacy was assessed with the new 20-item PHLAT. Psychometric analyses were performed to assess item characteristics and to generate a shortened, 10-item version (PHLAT-10).

RESULTS

A total of 182 caregivers were recruited. Although 99% had adequate literacy skills, only 17% had better than ninth-grade numeracy skills. Mean score on the PHLAT was 68% (standard deviation 18); for example, only 47% of caregivers could correctly describe how to mix infant formula from concentrate, and only 69% could interpret a digital thermometer to determine whether an infant had a fever. Higher performance on the PHLAT was significantly correlated (P < .001) with education, literacy skill, and numeracy level (r = 0.29, 0.38, and 0.55 respectively). Caregivers with higher PHLAT scores were also more likely to interpret age recommendations for cold medications correctly (odds ratio 1.6, 95% confidence interval 1.02, 2.6). Internal reliability on the PHLAT was good (Kuder-Richardson coefficient of reliability = 0.76). The PHLAT-10 also demonstrated good validity and reliability.

CONCLUSIONS

Many parents do not understand common health information required to care for their infants. The PHLAT and PHLAT-10 have good reliability and validity and may be useful tools for identifying parents who need better communication of health-related instructions.

Impact of false-positive newborn metabolic screening results on early health care utilization

PURPOSE

To analyze the association between false-positive newborn screening results and health care utilization.

METHODS

We surveyed parents regarding their children's health care utilization. Parents of children who received false-positive newborn screening results were primarily enrolled by a screening laboratory in Pennsylvania. Parents of children with normal results were recruited through the Massachusetts birth registry. We used bivariate tests and multivariate regression to assess the association between newborn screening results and primary care utilization, emergency room use, and hospitalization by the age of 6 months.

RESULTS

Our sample included 200 children with false-positive results and 137 with normal results. Variation in recruitment strategies led to sample children with false-positive results being more likely to be non-white, have unmarried parents, and be of lower socioeconomic status. After adjusting for significant covariates, such as age, race, and socioeconomic status, there were no significant associations between newborn screening results and child health care utilization.

CONCLUSIONS

Despite the reported negative psychosocial effects of false-positive results, our study found no impact on early health care utilization. These results may assist in economic analyses of newborn screening as they suggest that medical costs associated with false-positive results are limited to the cost of diagnostic testing and follow-up.

Health literacy and child health promotion: implications for research, clinical care, and public policy

The nation's leading sources of morbidity and health disparities (eg, preterm birth, obesity, chronic lung disease, cardiovascular disease, type 2 diabetes, mental health disorders, and cancer) require an evidence-based approach to the delivery of effective preventive care across the life course (eg, prenatal care, primary preventive care, immunizations, physical activity, nutrition, smoking cessation, and early diagnostic screening). Health literacy may be a critical and modifiable factor for improving preventive care and reducing health disparities. Recent studies among adults have established an independent association between lower health literacy and poorer understanding of preventive care information and poor access to preventive care services. Children of parents with higher literacy skills are more likely to have better outcomes in child health promotion and disease prevention. Adult studies in disease prevention have suggested that addressing health literacy would be an efficacious strategy for reducing health disparities. Future initiatives to reduce child health inequities should include health-promotion strategies that meet the health literacy needs of children, adolescents, and their caregivers.

Newborn screening: an appeal for improved parent education

OBJECTIVE

The purpose of this study, which was part of a larger investigation of newborn screening (NBS) for cystic fibrosis (CF), was to learn how parents were informed about NBS and obtain their suggestions for improving the process of educating parents about NBS.

METHOD

Qualitative study using directed and summative content analyses was conducted on 100 interviews with 193 parents of 100 newborns recruited from 4 clinical populations including parents of infants with (1) a CF diagnosis, (2) one CF mutation and therefore CF carriers, (3) congenital hypothyroidism, and (4) normal screening results.

RESULTS

Parents described much inconsistency in the timing of and methods used to inform them about NBS. Mothers with higher income were 3.69 times more likely to receive information before their infants' births than mothers with lower income. Parents recommended improving verbal and written communication with parents about NBS at multiple junctures from preconception to the infant's first few days of life. Parents suggested that providers take time to explain the purpose and importance of NBS, which diseases are included in testing, and when parents can expect results.

CONCLUSION

These findings suggest a need to establish evidence-based guidelines for informing parents about NBS.

Informing parents about expanded newborn screening: influences on provider involvement

OBJECTIVE

Expanded newborn screening (NBS) identifies some disorders for which clinical benefit is uncertain, as well as "incidental" findings (eg, carrier status), thus enhancing the need to inform parents about NBS before sample collection.

METHODS

A self-complete survey was sent to a cross-sectional, stratified, random sample of 5 provider groups in Ontario (obstetricians, midwives, family physicians, pediatricians, and nurses). Univariate and multivariate analyses were used to investigate the effects of core beliefs, perceived barriers, and demographic characteristics on the reported frequency of informing parents about NBS before sample collection.

RESULTS

Virtually all of the midwives and almost half of the nurses reported discussing NBS with parents, whereas less than one sixth of the physicians did so. Providers who perceived a responsibility to inform parents were 3 times more likely to report doing so than those who did not perceive this responsibility (odds ratio: 2.9 [95% confidence interval: 2.1-4.1]). Those who lacked confidence to inform parents were 70% less likely to discuss NBS with parents compared with those who did not experience this cognitive barrier (odds ratio: 0.3 [95% confidence interval: 0.2-0.4]). Controlling for these covariates, family physicians and obstetricians were more likely than pediatricians to inform parents.

CONCLUSIONS

These results provide guidance for capacity building among providers who are positioned to inform parents about NBS before sample collection. Our findings call for targeted educational interventions that consider patterns of provider practice related to prenatal and NBS care, seek to redress confidence limitations, and engage key provider groups in the importance of this professional responsibility.

Ethical, legal, and social concerns about expanded newborn screening: fragile X syndrome as a prototype for emerging issues

Technology will make it possible to screen for fragile X syndrome and other conditions that do not meet current guidelines for routine newborn screening. This possibility evokes at least 8 broad ethical, legal, and social concerns: (1) early identification of fragile X syndrome, an "untreatable" condition, could lead to heightened anxiety about parenting, oversensitivity to development, alterations in parenting, or disrupted bonding; (2) because fragile X syndrome screening should be voluntary, informed consent could overwhelm parents with information, significantly burden hospitals, and reduce participation in the core screening program; (3) screening will identify some children who are or appear to be phenotypically normal; (4) screening might identify children with other conditions not originally targeted for screening; (5) screening could overwhelm an already limited capacity for genetic counseling and comprehensive care; (6) screening for fragile X syndrome, especially if carrier status is disclosed, increases the likelihood of negative self-concept, societal stigmatization, and insurance or employment discrimination; (7) screening will suggest risk in extended family members, raising ethical and legal issues (because they never consented to screening) and creating a communication burden for parents or expanding the scope of physician responsibility; and (8) screening for fragile X syndrome could heighten discrepancies in how men and women experience genetic risk or decide about testing. To address these concerns we recommend a national newborn screening research network; the development of models for informed decision-making; materials and approaches for helping families understand genetic information and communicating it to others; a national forum to address carrier testing and the disclosure of secondary or incidental findings; and public engagement of scientists, policy makers, ethicists, practitioners, and other citizens to discuss the desired aims of newborn screening and the characteristics of a system needed to achieve those aims.

Imparting carrier status results detected by universal newborn screening for sickle cell and cystic fibrosis in England: a qualitative study of current practice and policy challenges

BACKGROUND

Universal newborn screening for early detection of children affected by sickle cell disorders and cystic fibrosis is currently being implemented across England. Parents of infants identified as carriers of these disorders must also be informed of their baby's result. However there is a lack of evidence for most effective practice internationally when doing so. This study describes current or proposed models for imparting this information in practice and explores associated challenges for policy.

METHODS

Thematic analysis of semi-structured interviews with Child Health Coordinators from all English Health Regions.

RESULTS

Diverse methods for imparting carrier results, both within and between regions, and within and between conditions, were being implemented or planned. Models ranged from result by letter to in-person communication during a home visit. Non-specialists were considered the best placed professionals to give results and a similar approach for both conditions was emphasised. While national guidance has influenced choice of models, other factors contributed such as existing service structures and lack of funding. Challenges included uncertainty about guidance specifying face to face notification; how best to balance allaying parental anxiety by using familiar non-specialist health professionals with concerns about practitioner competence; and extent of information parents should be given. Inadequate consideration of resource and service workload was seen as the main policy obstacle. Clarification of existing guidance; more specific protocols to ensure consistent countrywide practice; integration of the two programmes; and 'normalising' carrier status were suggested as improvements.

CONCLUSION

Differing models for communicating carrier results raise concerns about equity and clinical governance. However, this variation provides opportunity for evaluation. Timely and more detailed guidance on protocols with clarification of existing recommendations is needed.

Facilitating behavior change with low-literacy patient education materials

OBJECTIVE

To describe a process for developing low-literacy health education materials that increase knowledge and activate patients toward healthier behaviors.

METHODS

We developed a theoretically informed process for developing educational materials. This process included convening a multidisciplinary creative team, soliciting stakeholder input, identifying key concepts to be communicated, mapping concepts to a behavioral theory, creating a supporting behavioral intervention, designing and refining materials, and assessing efficacy.

RESULTS

We describe the use of this process to develop a diabetes self-management guide.

CONCLUSIONS

Developing low-literacy health education materials that will activate patients toward healthier behaviors requires attention to factors beyond reading level.
