Committee opinion no. 616: Newborn screening and the role of the obstetrician-gynecologist

Women's Choices Regarding Use of Their Newborns' Residual Dried Blood Samples in Research

OBJECTIVE

To determine the proportion of informed choices women made about donating their newborns' blood samples for research.

DESIGN

A quantitative analysis of informed choice using data on women's knowledge and attitudes from a descriptive, cross-sectional survey.

SETTING

The state of Michigan.

PARTICIPANTS

Women (N = 69, ≥18 years old) who had (a) newborns 0 to 3 months of age, (b) yes or no decisions regarding use of the blood sample for research on file, (c) no evidence of an infant death in the state database, (d) completed the knowledge scale, (e) completed the attitude scale, and (f) recalled the decision (i.e., yes or no) about donating blood samples.

METHODS

We used the multidimensional measure of informed choice to calculate the proportion of informed choices in data on women's knowledge, attitudes, and decisions about biospecimen research.

RESULTS

Fifty-five percent (38/69) of participants made informed choices about donating newborn blood samples for research, and 45% made uninformed choices (31/69). Inadequate knowledge about biospecimen research contributed to 87% of uniformed choices (27/31). Participants who declined to donate their newborns' blood samples struggled with making decisions consistent with their values.

CONCLUSION

Nearly half of the participants made uninformed choices about donating the blood samples of their newborns for research. Women need more information about genetics and the storage and research use of newborns' blood samples to make informed choices. Nurses need to be made aware of the ethical, legal, and social implications of such research because they are primary sources of advocacy, information, and support for childbearing women and may be charged with overseeing or obtaining informed consent. Additional research with larger, more diverse samples is needed.

Perspectives of newborn hearing screening in resource constrained settings

Newborn hearing screening is an effective strategy for early identification of hearing loss in the newborn which result in early intervention and best outcome. However implementing universal screening strategy is a challenge in many resource constrained settings. There are various limitations towards successful implementation of hearing screening program in the developing countries. The cost effectiveness of the screening program also needs to be considered in a resource constrained settings. We attempt to provide a viewpoint that can be potentially helpful for the successful implementation of hearing screening in a resource constrained settings of the developing countries.

Lessons learnt from implementing change in newborn bloodspot screening processes over more than a decade: Midwives, genetics and education

OBJECTIVE

To explore midwives' roles and education requirements in newborn bloodspot screening (NBS) for genetic conditions, as programs and supporting education evolve over time.

BACKGROUND

NBS processes are evolving and will continue to evolve with new genetic and genomic technologies. Midwives have a critical role in facilitating NBS, as they are the primary healthcare professional to interact with parents at the time of collecting the bloodspot. As new consent processes and genomic technologies are incorporated into NBS, midwives need to stay up-to-date with these changes, so that parents can make an informed decision about having the test and future use of the DNA sample.

RESEARCH DESIGN/SETTING

We used a cross-sectional approach to analyse midwives' knowledge and behaviour in 2005/6 and 2016, with changes in NBS processes and education introduced in 2011.

FINDINGS

We found midwives' NBS knowledge improved in 8/18 areas after a 10-year period, mostly related to process changes, but there was also an increase in misconceptions regarding which conditions are screened. Areas of significant improvement were not consistently explained by participation in continuing professional development (CPD). We found midwives used official brochures and NBS collection cards to guide discussions with families. Changes to the NBS collection cards, together with the content of CPD materials, aligned with the significant improvements and deficits we observed. When considering potential changes to future maternity care that incorporates emerging genomic technologies, midwives indicated the main barrier was their lack of knowledge; the majority (60.3%) reported supervision support to attend genomics CPD.

KEY CONCLUSIONS

Changes in NBS practice should be implemented through multifaceted programs that include education sessions and procedural prompts. The NBS collection card should be seen not just as a legal consent document but also as an educational tool.

IMPLICATIONS FOR PRACTICE

As NBS programs evolve through the addition of conditions screened for or changes to technology or consent processes, multiple strategies should be applied to upskill midwives to ensure they can best support parents to make informed choices.

National Survey Assessment of the United States' Pediatric Residents' Knowledge, Attitudes, and Practices Regarding Newborn Screening

A pediatrician's approach to newborn screening (NBS) impacts patient care. Some physicians have reported not being well prepared to inform families about a positive NBS and recommend further follow-up. The knowledge and approach of categorical pediatric residents (RES) in the United States regarding NBS is not known. They were anonymously surveyed via listserv maintained by American Academy of Pediatrics. A total of 655 responses were analyzed. The mean composite knowledge score (CKS) was 17.7 (SD 1.8), out of maximum 21. Training level (p = 0.001) and completing NICU rotation (p < 0.001) predicted higher CKS. Most RES agreed that NBS is useful and pediatricians play an important role in the NBS process, however, only 62% were comfortable with counseling. Higher level RES were more likely to follow NBS results in clinic (p = 0.0027) and know the contact agency for results (p < 0.001). Most RES wanted more NBS training during residency and were not aware of clinical algorithms like ACTion sheets developed by American College of Medical Genetics. We concluded that although RES have sufficient knowledge about NBS, there is a need for earlier RES education on available tools for NBS to enhance their comfort level and improve practices such as educating parents about the NBS process.

Mothers' Decisions About Donating Newborns' Blood Spots for Research: A Qualitative Study

Residual dried blood spots from millions of newborns are being stored and used for research. The state of Michigan proactively developed a broad consent process for research use of newborns' blood spots. However, the extent to which mothers make informed choices about this research is unclear. A descriptive, qualitative study was conducted examining this issue. Twenty-nine observations of the consent process and 20 semistructured interviews were conducted with mothers on the postpartum unit of a large, academic hospital in Michigan. Content analysis of the transcripts was conducted. While most mothers agreed to donate the blood spots (n = 14/20; 70%), findings indicated that most decisions were uninformed (n = 16/20; 80%), as mothers lacked knowledge of biobanking research. Misunderstandings about anonymity, the consenter's credentials, and entity conducting the research seemed to influence decision making. Suggestions for improving the consent process include (1) changing the venue of blood spot education and consent from the postpartum period to the perinatal period, (2) strengthening the depth of information and delivery of information provided about the topic, including ethical and values clarification, and (3) increasing consenter education and training. Implementation may help increase the proportion of informed decisions.

Parental awareness of newborn bloodspot screening in Ireland

BACKGROUND

There is little known regarding how familiar parents are with the newborn bloodspot screening (NBS) test or how well parents of a child with a screen-detected condition understand that condition initially.

AIM

The study aim was to examine parental NBS awareness and conditions screened.

METHODS

Two studies were conducted: [1] Parents of children with cystic fibrosis (CF) detected via NBS and subsequently, diagnosed (n = 124) completed a telephone questionnaire regarding information they received at the time of NBS. [2] A cross-sectional study of women (n = 662 (58%) antenatal; n = 480 (42%) postnatal) attending three large maternity hospitals completed a questionnaire addressing NBS awareness.

RESULTS

Mothers incorrectly identified diabetes/asthma (35% postnatal; 70% antenatal) and sickle cell disease (26%) as conditions on NBS in Ireland. Phenylketonuria was correctly identified by 48/26%, CF by 82/64%, and congenital hypothyroidism by 35/13% postnatal and antenatal women respectively. Of parents of children screen-detected and subsequently, diagnosed with CF, only half (n = 63; 51%) reported awareness at the time of NBS that CF was included. These results should be used to improve the information provided to expectant mothers and to inform health professionals' initial discussions with parents about their child's diagnosis, building on parents' pre-existing knowledge.

Carrier screening for single gene disorders

Screening for genetic disorders began in 1963 with the initiation of newborn screening for phenylketonuria. Advances in molecular technology have made both newborn screening for newborns affected with serious disorders, and carrier screening of individuals at risk for offspring with genetic disorders, more complex and more widely available. Carrier screening today can be performed secondary to family history-based screening, ethnic-based screening, and expanded carrier screening (ECS). ECS is panel-based screening, which analyzes carrier status for hundreds of genetic disorders irrespective of patient race or ethnicity. In this article, we review the historical and current aspects of carrier screening for single gene disorders, including future research directions.

An evaluation of pregnant women's knowledge and attitudes about newborn bloodspot screening

OBJECTIVES

research suggests that information provided to parents about newborn bloodspot screening (NBS) can be inconsistent. The majority of international NBS programmes recommend that parents should receive information about NBS in the antenatal period, however prior studies have mostly focused on postnatal women's knowledge, with no quantitative study of women's knowledge in the antenatal period conducted to date. Thus, the aim of this study was to determine if antenatal women received information about NBS in the antenatal period and to evaluate their knowledge and attitudes about NBS.

DESIGN/PARTICIPANTS

we conducted a cross-sectional study among antenatal attendees at three maternity hospitals in Ireland. A total of 662 antenatal women (≥36 weeks gestation) were recruited into the study (279 primiparous, 368 multiparous). Women were asked to complete a self reported knowledge and attitude questionnaire about NBS.

FINDINGS

primiparity (OR 2.75; 95% CI 1.65, 4.59) lower educational status (OR 1.79; 95% CI 1.02, 3.15) and not having private health insurance (OR 1.84; 95% CI 1.19, 2.85) were independently associated with poor NBS knowledge. Fourteen per cent of antenatal women recalled receiving an information leaflet about NBS, yet over 87 % reported that they would like more information. Thirty four per cent of women agreed that they understand everything they need to know about NBS.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

the process of providing women with information about NBS in the antenatal period is inconsistent; consequently their awareness about NBS is limited. To make an informed choice about NBS women require information to be provided in a more structured format. There are many missed opportunities in the antenatal period for maternity care providers to provide women with information about NBS. Our study recommends that healthcare providers should have a more formal and structured approach with regard to the provision of information about NBS in the antenatal period. This could be achieved by incorporating NBS education into antenatal education classes or through multimedia while women are waiting in the antenatal clinic. Healthcare providers may need education about the importance and benefits of providing women with information about NBS in the antenatal period.

Prenatal Education of Parents About Newborn Screening and Residual Dried Blood Spots: A Randomized Clinical Trial

IMPORTANCE

Research clearly indicates that current approaches to newborn blood spot screening (NBS) education are ineffective. Incorporating NBS education into prenatal care is broadly supported by lay and professional opinion.

OBJECTIVE

To determine the efficacy and effect of prenatal education about newborn screening and use of residual dried blood spots (DBS) in research on parental knowledge, attitudes, and behaviors.

DESIGN, SETTING, AND PARTICIPANTS

A randomized clinical trial of prenatal educational interventions, with outcomes measured by survey at 2 to 4 weeks postpartum. Participants were recruited from obstetric clinics in Salt Lake City, Utah; San Francisco, California; and the Bronx, New York. Eligible women were English- or Spanish-speaking adults and did not have a high-risk pregnancy. A total of 901 women were enrolled. Participants who completed the follow-up survey included 212 women in the usual care group (70% retention), 231 in the NBS group (77% retention), and 221 women in the NBS + DBS group (75% retention). Those who completed the survey were similar across the 3 groups with respect to age, ethnicity, race, education, marital status, income, obstetric history, and language.

INTERVENTIONS

Participants were randomized into 1 of 3 groups: usual care (n = 305), those viewing an NBS movie and brochure (n = 300), and those viewing both the NBS and DBS movies and brochures (n = 296).

MAIN OUTCOMES AND MEASURES

Two to four weeks postpartum, women completed a 91-item survey by telephone, addressing knowledge, attitudes, and behavior with respect to opting out of NBS or DBS for their child.

RESULTS

A total of 901 women (mean age, 31 years) were randomized and 664 completed the follow-up survey. The total correct responses on the knowledge instrument in regard to NBS were 69% in the usual care group, 79% in the NBS group, and 75% in the NBS + DBS group, a significant between-group difference (P < .05). Although all groups showed strong support for NBS, the percentage of women who were "very supportive" was highest in the NBS group (94%), followed by the NBS + DBS group (86%) and was lowest in the usual care group (73%) (P < .001). The interventions were not associated with decisions to decline newborn screening or withdraw residual DBS. Nine women stated that they had declined NBS (all the usual care group; P < .001). With respect to DBS, 5 participants indicated that they contacted the health department to have their child's sample withdrawn after testing: 3 in the NBS + DBS group and 2 in the usual care group (P = .25).

CONCLUSIONS AND RELEVANCE

Educational interventions can be implemented in the prenatal clinic, using multimedia tools and electronic platforms. Prenatal education is effective in increasing postnatal knowledge and support for these programs. These results are relevant to other contexts in which residual clinical specimens and data are used for research purposes.

Current recommendations: Screening for Mendelian disorders

Over the last 50 years, screening for Mendelian disorders has progressed from screening of neonates for phenylketonuria (PKU) to screening of healthy individuals in the preconception or prenatal setting for more than 100 disorders. Traditional carrier screening has been based on ethnicity, and, as ethnic distinctions become less defined, the ability to screen effectively has become increasingly more limited. At the same time, advances in molecular technology have produced large screening panels without reliance on ethnicity. This article outlines the historical and traditional use of single gene carrier screening.
