Challenging the dogma of the healthy heterozygote: Implications for newborn screening policies and practices.

Heterozygous (carrier) status for an autosomal recessive condition is traditionally considered to lack significance for an individual's health, but this assumption has been challenged by a growing body of evidence. Carriers of several autosomal recessive disorders and some X-linked diseases are potentially at risk for the pathology manifest in homozygotes. This minireview provides an overview of the literature regarding health risks to carriers of two common autosomal recessive conditions on the Recommended Uniform Screening Panel: sickle cell disease [sickle cell trait (SCT)] and cystic fibrosis (CF). We also consider and comment on bioethical and policy implications for newborn blood screening (NBS). Health risks for heterozygotes, while relatively low for individuals, are often influenced by intrinsic (e.g., other genomic variants or co-morbidities) and extrinsic (environmental) factors, which present opportunities for personalized genomic medicine and risk counseling. They create a special challenge, however, for developing screening/follow-up policies and for genetic counseling, particularly after identification and reporting of heterozygote status through NBS. Although more research is needed, this minireview of the SCT and CF literature to date leads us to propose that blanket terms such as "healthy heterozygotes" or "unaffected carriers" should be superseded in communications about NBS results, in favor of a more nuanced paradigm of setting expectations for health outcomes with "genotype-to-risk." In the molecular era of NBS, it remains clear that public health needs to become better prepared for the full range of applied genetics.

Experience with Parent Follow-Up for Communication Outcomes after Newborn Screening Identifies Carrier Status.

OBJECTIVE: To conduct interviews with a multiyear sample of parents of infants found to have heterozygous status for sickle cell hemoglobinopathy or cystic fibrosis during newborn blood screening (NBS). STUDY DESIGN: Interviewers with clinical backgrounds telephoned parents, and followed a structured script that blended follow-up and research purposes. Recruiting followed several steps to minimize recruiting bias as much as possible for a NBS study. RESULTS: Follow-up calls were conducted with parents of 426 infant carriers of sickle cell hemoglobinopathy, and 288 parents of cystic fibrosis carriers (34.8% and 49.6% of those eligible). Among these, 27.5% and 7.8% had no recollection of being informed of NBS results. Of those who recalled a provider explanation, 8.6% and 13.0% appraised the explanation negatively. Overall, 7.4% and 13.2% were dissatisfied with the experience of learning about the NSB result. Mean anxiety levels were low but higher in the sickle cell hemoglobinopathy group (P < .001). Misconceptions that the infant might get the disease were present in 27.5% and 7.8% of parents (despite zero actual risk for disease). Several of these data were significantly predicted by NBS result, health literacy, parental age, and race/ethnicity factors. CONCLUSIONS: Patient-centered public health follow-up can be effective after NBS identifies carrier status. Psychosocial complications were uncommon, but harms were substantial enough to justify mitigation.

Vulnerable Child Syndrome and Newborn Screening Carrier Results for Cystic Fibrosis or Sickle Cell.

OBJECTIVES: To measure parental perceptions of child vulnerability, as a precursor to developing a population-scale mechanism to mitigate harm after newborn screening. STUDY DESIGN: Participants were parents of infants aged 2-5 months. Parental perceptions of child vulnerability were assessed with an adapted version of the Vulnerable Baby Scale. The scale was included in the script for a larger study of telephone follow-up for 2 newborn blood screening samples (carrier status for cystic fibrosis or sickle cell hemoglobinopathy). A comparison sample was added using a paper survey with well-baby visits to an urban/suburban clinic. RESULTS: Sample sizes consisted of 288 parents in the cystic fibrosis group, 426 in the sickle cell hemoglobinopathy group, and 79 in the clinic comparison group. Parental perceptions of child vulnerability were higher in the sickle cell group than cystic fibrosis group (P < .0001), and both were higher than the clinic comparison group (P < .0001). Parental perceptions of child vulnerability were inversely correlated with parental age (P < .002) and lower health literacy (P < .015, sickle cell hemoglobinopathy group only). CONCLUSIONS: Increased parental perceptions of child vulnerability seem to be a bona fide complication of incidental newborn blood screening findings, and healthcare professionals should be alert to the possibility. From a public health perspective, we recommend routine follow-up after incidental findings to mitigate psychosocial harm.

Does Lack of "Genetic-Relative Family Health History" Represent a Potentially Avoidable Health Disparity for Adoptees?

Many adoptees face a number of challenges relating to separation from biological parents during the adoption process, including issues concerning identity, intimacy, attachment, and trust, as well as (for older adopted children) language and other cultural challenges. One common health challenge faced by adoptees involves lack of access to genetic-relative family health history (GRFHx). Lack of GRFHx represents a disadvantage due to a reduced capacity to identify diseases and recommend appropriate screening for conditions for which the adopted person may be at increased risk. In this article, we draw out common features of traditionally understood "health disparities" in order to identify analogous features in the context of adoptees' lack of GRFHx.

The limits of traditional approaches to informed consent for genomic medicine.

This paper argues that it will be important for new genomic technologies to recognize the limits of traditional approaches to informed consent, so that other-regarding implications of genomic information can be properly contextualized and individual rights respected. Respect for individual autonomy will increasingly require dynamic consideration of the interrelated dimensions of individual and broader community interests, so that the interests of one do not undermine fundamental interests of the other. In this, protection of individual rights will be a complex interplay between individual and community concerns.

Effects of immediate telephone follow-up with providers on sweat chloride test timing after cystic fibrosis newborn screening identifies a single mutation.

OBJECTIVE: To assess whether reporting "possible cystic fibrosis (CF)" newborn screening (NBS) results via fax plus simultaneous telephone contact with primary care providers (PCPs) versus fax alone influenced 3 outcomes: undergoing a sweat chloride test, age at sweat chloride testing, and undergoing sweat testing before age 8 weeks. STUDY DESIGN: This was a retrospective cohort comparison of infants born in Wisconsin whose PCP received a telephone intervention (n = 301) versus recent historical controls whose PCP did not (n = 355). Intervention data were collected during a longitudinal research and quality improvement effort; deidentified comparison data were constructed from auxiliary NBS tracking information. Parametric and nonparametric statistical analyses were performed for group differences. RESULTS: Most infants (92%) with "possible CF" NBS results whose PCP lacked telephone intervention ultimately underwent sweat testing, underlining efficacy for fax-only reporting. Telephone intervention was significantly associated with improvements in the infants undergoing sweat testing at age ≤6 weeks and <8 weeks and a slight, statistically nonsignificant 3.5-day reduction in the infants' age at sweat testing. The effect of telephone intervention was greater for PCPs whose patients underwent sweat testing at community-affiliated medical centers versus those whose patients did so at academic medical centers (P = .008). CONCLUSION: Reporting "possible CF" NBS results via fax plus simultaneous telephone follow-up with PCPs increases the rate of sweat chloride testing before 8 weeks of age, when affected infants are more likely to receive full benefits of early diagnosis and treatment.

Community-recruited parent perspectives of concern dismissal by pediatric providers.

INTRODUCTION: Effective communication is a central tenet of family centered care, yet parent concerns are sometimes un- or underattended to by pediatric providers. This study aimed to explore the prevalence of, and factors related to, parental perceptions of concern dismissal by pediatric providers. METHOD: In Spring 2020, 270 community-recruited parents of children ages 6-12 years (74% White, 74% female, 69% married) responded to an online survey about perceived concern dismissal experiences with their children. Characteristics of concern dismissal, differences in concern dismissal occurrence by parent factors, and emotional and practical impacts were assessed and explored. RESULTS: Thirty-three percent reported having experienced concern dismissal, most often in pediatric primary care settings. Concern dismissal was reported more frequently among parents employed in health care settings than those without health care employment histories. Most dismissed concerns related to the child's physical health and many incidents were characterized by provider impoliteness or provision of less testing or treatment than expected or desired. Many parents expressed disappointment in the health care system after experiences of concern dismissal. DISCUSSION: Concern dismissal was found to be common and upsetting for community-recruited parents. Future research should incorporate child and provider perspectives with demographically diverse samples. Pediatric providers should continue to work toward implementation of family centered care to decrease the likelihood of perceived dismissal by thoroughly recognizing and responding to concerns presented by parents and caregivers of pediatric patients.

A qualitative secondary evaluation of statewide follow-up interviews for abnormal newborn screening results for cystic fibrosis and sickle cell hemoglobinopathy.

PURPOSE: The purpose of this qualitative analysis was to assess parental acceptability of large-scale, telephone follow-up regarding their infants' newborn screening (NBS) results, indicating carrier status for sickle cell hemoglobinopathy (SCH) and cystic fibrosis (CF). METHODS: Analysis of 195 interview transcripts focused on parents' responses to two open-ended questions: "What was your reaction to being called by me?" and "What do you think of the state NBS program having follow-up people calling parents like you?" Responses were coded using conventional content analysis procedures, and nonparametric tests were performed to analyze quantitative data. RESULTS: Most parents reported favorable opinions about the follow-up. Favorable opinions were associated with several emotional reactions to receiving follow-up (P <0.001) and three reasons why parents found the interview beneficial (P < 0.05): it provided information, clarified NBS results, and answered questions. Seventeen parents of SCH carriers reportedly had not been told their infant's NBS results and received them for the first time during the follow-up interview. CONCLUSION: Parents of CF and SCH carrier infants had favorable opinions and identified specific benefits to receiving follow-up contact. This analysis demonstrates an information deficit among carrier parents and illustrates the importance of NBS follow-up and need for comprehensive communication and counseling.

Effort required to contact primary care providers after newborn screening identifies sickle cell trait.

People with heterozygous status for sickle cell disease (also called sickle cell trait) are essentially healthy, but evidence of rare health problems has increased interest in screening adolescents and young adults prior to enlisting in athletics or military service. Ironically, almost everyone with sickle cell trait is already identified during routine newborn screening for sickle cell disease, but this identification may never reach the parents. As part of a larger statewide study of communication after newborn screening, we decided to document the amount of labor required to connect sickle cell trait screening results with primary care providers (PCPs). Case review methods examined records and call logs from the first 150 cases in a 42-month project. Our study procedures identified PCPs for 136 of 150 infants (90.6%); a total of 266 phone calls were needed. We identified 9 categories of experiences, ranging from incorrect baby names to restrictions on accepting Medicaid patients. Cases demonstrate that it is possible to connect with most PCPs after newborn screening despite warnings about difficulties with this population. Success was due to persistence, relationships with clinics and hospitals, and Internet search capabilities. If sickle cell trait identification is necessary to protect health, then only modest increases in effort will be needed to reduce disparities in service.

Parental Preferences about Policy Options Regarding Disclosure of Incidental Genetic Findings in Newborn Screening: Using Videos and the Internet to Educate and Obtain Input.

Our objective was to develop and test a new approach to obtaining parental policy guidance about disclosure of incidental findings of newborn screening for cystic fibrosis (CF), including heterozygote carrier status and the conditions known as CFTR-related metabolic syndrome (CRMS) and/or cystic fibrosis screen positive inconclusive diagnosis, CFSPID. The participants were parents of infants up to 6 months old recruited from maternity hospitals/clinics, parent education classes and stores selling baby products. Data were collected using an anonymous, one-time Internet-based survey. The survey introduced two scenarios using novel, animated videos. Parents were asked to rank three potential disclosure policies-Fully Informed, Parents Decide, and Withholding Information. Regarding disclosure of information about Mild X (analogous to CRMS/CFSPID), 57% of respondents ranked Parents Decide as their top choice, while another 41% ranked the Fully Informed policy first. Similarly, when considering disclosure of information about Disease X (CF) carrier status, 50% and 43% gave top rankings to the Fully Informed and Parents Decide policies, respectively. Less than 8% ranked the Withholding Information policy first in either scenario. Data from value comparisons suggested that parents believed knowing everything was very important even if they became distressed. Likewise, parents preferred autonomy even if they became distressed. However, when there might not be enough time to learn everything, parents showed a slight preference for deferring decision-making. Because most parents strongly preferred the policies of full disclosure or making the decision, rather than the withholding option for NBS results, these results can inform disclosure policies in NBS programs, especially as next-generation sequencing increases incidental findings.

Improving communication between doctors and parents after newborn screening.

BACKGROUND: Newborn screening (NBS) enables early treatment, and some consider it a natural vehicle for genetic screening. Bioethicists argue for caution since families of infants with carrier status can develop psychosocial complications. This paper describes the methods and feasibility of Wisconsin's statewide project for quality improvement of communication and psychosocial outcomes after NBS. METHODS: When NBS identifies carrier status for cystic fibrosis or sickle cell, we contact primary care providers (PCPs), answer questions, and invite them to rehearse informing the parents. Three months later, we telephone the parents, assess knowledge and psychosocial outcomes, provide counseling, and assist with self-referral to further resources. Afterward, evaluation surveys are provided to the parents, to be returned anonymously. RESULTS: Birthing facilities provided accurate PCP names for 73% of 817 infants meeting inclusion criteria; we identified PCPs for 21% more. We reached 47.3% of PCPs in time to invite a rehearsal; 60% of these accepted. We successfully called 50.2% of eligible parents; 61% recalled a PCP explanation, and 48.5% evaluated the explanation favorably. Evaluations by parents with limited health literacy were less favorable. CONCLUSION: It is feasible to follow parents for psychosocial outcomes after NBS. Preliminary data about communication is mixed, but further data will describe psychosocial outcomes and investigate outcomes' associations with communication.

Benefit of Report Card Feedback After Point-of-Care Assessment of Communication Quality Indicators.

PURPOSE: Communication is crucial for patient experience and biomedical outcomes. Training programs improve communication but are too resource-intensive for sustained use across an entire health care organization. This study demonstrates in a heterogeneous set of encounters the efficacy of quantitative feedback on two groups of physician communication behaviors: 1) jargon explanation, and 2) assessment of patient understanding. METHODS: We used a secure Internet application to audio-record conversations between primary care physicians and 54 patients. Transcripts were quantitatively abstracted using explicit-criteria definitions for assessments of understanding and jargon explanations. These data were conveyed to physicians using a previously tested report card. Finally, physicians were audio-recorded with 48 other patients and compared against their baseline. RESULTS: Baseline transcripts included an average of 15.5 unique jargon words. Many words were spoken more than once so the total jargon count averaged 25.1. Jargon explanations were infrequent (median of 2.6/transcript). The jargon explanation ratio (fraction of jargon words spoken after or alongside a jargon explanation for that word) averaged 0.26 out of 1.0. Assessments of understanding were found in 61.1% of transcripts, but most were "OK?" questions (median of 2.22/transcript) or close-ended assessments of understanding (median of 0.59/transcript). After the report card, use of jargon explanations improved to a median of 4.8/transcript (P<0.001), and the jargon explanation ratio improved to 0.37 (P<0.02). Assessments of understanding improved to 81.3% of transcripts (P<0.03), largely due to increased use of close-ended assessments of understanding to 1.08/transcript (P<0.006). CONCLUSIONS: It is feasible to audio-record at the point of care, abstract transcripts at a central office and improve physician-to-patient communication quality via a report card. A larger, multifaceted program may improve patient experience and biomedical outcomes.

Sources of ethical conflict in medical housestaff training: a qualitative study.

PURPOSE: Despite increased emphasis on medical ethics and professionalism in medical education, concern about unethical and unprofessional behavior by physicians is widespread. This study sought to identify and classify the range of work-related ethical conflicts experienced by medical house officers. METHODS: We performed a qualitative study using data from in-depth interviews conducted in 2001 with 31 internal medicine residents in one traditional and one primary care residency. Using the constant comparative method, we explored work-related experiences during housestaff training that involved ethical conflict with patients or colleagues. RESULTS: The interviews revealed five categories of ethical conflict: concern over telling the truth, respecting patients' wishes, preventing harm, managing the limits of one's competence, and addressing performance of others that is perceived to be inappropriate. Conflicts occurred between residents and attending physicians, patients or families, and other residents. Many of the conflicts were exacerbated by the function of the hierarchical structure in residency training. CONCLUSIONS: This study provides a classification of work-related ethical conflicts that houseofficers experience, which may be used to improve the working environment for residents and support their professional development. By attending to the challenges that residents face, particularly previously underemphasized conflicts concerning competence and performance, this framework can be used to enhance education in ethics and professionalism.

Linguistic markers of emotion in mothers of sickle cell carrier infants: what are they and what do they mean?

OBJECTIVE: The objectives were to examine emotion-related language in mothers' narratives about newborn screening, and test the correlations between language and self-reported emotion and behavior. METHODS: Transcripts of interviews with mothers of infant sickle cell carriers were analyzed with word count software for the prevalence of emotion-related words in narratives about newborn screening. Word counts were compared to population norms for spoken language using one-sample t-tests. Anxiety-related words were correlated with self-reported anxiety and avoidance of genetic testing. RESULTS: 187 transcripts were analyzed, in which there was a higher percentage of anxiety words (m=.38%) than population norms (m=.18%), t(186)=10.59, p<.001, CI=.16-.23. Anxiety-related word use was positively correlated with self-reported previous anxiety, rs(185)=.24, p=.001. Self-reported previous anxiety, but not word use, was correlated with mothers' avoidance of undergoing genetic testing themselves rs(152)=.25, p=.002. CONCLUSION: Mothers of sickle cell carrier infants reported anxiety upon learning their child's condition. Anxiety-related words in maternal narratives were correlated with their reports of past, but not present, emotions. PRACTICE IMPLICATIONS: Researchers and clinicians should use caution in assuming that word choices reflect state emotions. Self-report methods may be preferable for predicting behavioral outcomes.

Improving the quality of physician communication with rapid-throughput analysis and report cards.

OBJECTIVE: Problems with clinician-patient communication negatively impact newborn screening, genetics, and all of healthcare. Training programs teach communication, but educational methods are not feasible for entire populations of clinicians. To address this healthcare quality gap, we developed a Communication Quality Assurance intervention. METHODS: Child health providers volunteered for a randomized controlled trial of assessment and a report card. Participants provided telephone counseling to a standardized parent regarding a newborn screening result showing heterozygous status for cystic fibrosis or sickle cell disease. Our rapid-throughput timeline allows individualized feedback within a week. Two encounters were recorded (baseline and after a random sample received the report card) and abstracted for four groups of communication quality indicators. RESULTS: 92 participants finished both counseling encounters within our rapid-throughput time limits. Participants randomized to receive the report card improved communication behaviors more than controls, including request for teach-back (p<0.01), opening behaviors (p=0.01), anticipate/validate emotion (p<0.001) and the ratio of explained to unexplained jargon words (p<0.03). CONCLUSION: The rapid-throughput report card is effective at improving specific communication behaviors. PRACTICE IMPLICATIONS: Communication can be taught, but this project shows how healthcare organizations can assure communication quality everywhere. Further implementation could improve newborn screening, genetics, and healthcare in general.

Frequency of high-quality communication behaviors used by primary care providers of heterozygous infants after newborn screening.

OBJECTIVE: To examine the quality of communication likely to be experienced by parents when being first informed about how newborn screening identified heterozygous "carrier" status for cystic fibrosis or sickle cell disease. METHODS: Primary care providers (PCPs) of infants found to have carrier status were telephoned over a 48-month period, and asked to rehearse with a standardized patient how they would inform the infants' parent(s). 214 rehearsal transcripts were abstracted using explicit criteria methods to measure the frequency of five categories of high-quality communication behaviors. RESULTS: Overall, PCPs used large amounts of jargon and failed to use high quality communication behaviors. On average, PCPs used 18.6 total jargon words (8.7 unique words), but explained 2.4 jargon words. The most frequent assessment of understanding was the close-ended version, although it was only seen in 129 of 214 transcripts. The most common organizing behavior was importance emphasis (121/214). Precautionary empathy was rare; the most frequent behavior was "instruction about emotion" (33/214). CONCLUSION: The limited use of high-quality communication behaviors in rehearsals raises concern about parental understanding, decision-making, and psychosocial outcomes after newborn screening. PRACTICE IMPLICATIONS: Measurement of specific behaviors may help PCPs to improve communication, and thereby improve the patient experience.

Factors that influence parents' experiences with results disclosure after newborn screening identifies genetic carrier status for cystic fibrosis or sickle cell hemoglobinopathy.

OBJECTIVE: Newborn screening (NBS) identifies genetic carriers for sickle cell hemoglobinopathy and cystic fibrosis. We aimed to identify factors during initial NBS carrier results disclosure by primary care providers (PCPs) that influenced parents' experiences and reactions. METHODS: Open-ended responses from telephone interviews with 270 parents of carriers were analyzed using mixed-methods. Conventional content analysis identified influential factors; chi-square tests analyzed relationships between factors and parent-reported reactions. RESULTS: Parents reported positive (35%) or negative (31%) reactions to results disclosure. Parents' experiences were influenced by specific factors: content messages (72%), PCP traits (47%), and aspects of the setting (30%). Including at least one of five specific content messages was associated (p<0.05) with positive parental reactions; omitting at least one of four specific content messages was associated (p<0.05) with negative parental reactions. Parents reported positive reactions when PCPs avoided jargon or were perceived as calm. Parents reported negative reactions to jargon usage and results disclosure by voicemail. CONCLUSION: Parents identified aspects of PCP communication which influenced their reactions and results disclosure experiences. PRACTICE IMPLICATIONS: Our findings suggest ways PCPs may improve communication of carrier results. PCPs should provide specific content messages and consider how their actions, characteristics, and setting can influence parental reactions.

Child health providers' precautionary discussion of emotions during communication about results of newborn genetic screening.

OBJECTIVE: To demonstrate a quantitative abstraction method for Communication Quality Assurance projects to assess physicians' communication about hidden emotions after newborn genetic screening. DESIGN: Communication quality indicator analysis. SETTING: Standardized parent encounters performed in practicing physicians' clinics or during educational workshops for residents. PARTICIPANTS: Fifty-nine pediatrics residents, 53 pediatricians, and 31 family physicians. INTERVENTION: Participants were asked to counsel standardized parents about a screening result; counseling was recorded, transcribed, and parsed into statements (each with 1 subject and 1 predicate). Pairs of abstractors independently compared statements with a data dictionary containing explicit-criteria definitions. OUTCOME MEASURES: Four groups of "precautionary empathy" behaviors (assessment of emotion, anticipation/validation of emotion, instruction about emotion, and caution about future emotion), with definitions developed for both "definite" and "partial" instances. RESULTS: Only 38 of 143 transcripts (26.6%) met definite criteria for at least 1 of the precautionary empathy behaviors. When partial criteria were counted, this number increased to 80 of 143 transcripts (55.9%). The most common type of precautionary empathy was the "instruction about emotion" behavior (eg, "don't be worried"), which may sometimes be leading or premature. CONCLUSIONS: Precautionary empathy behaviors were rare in this analysis. Further study is needed, but this study should raise concerns about the quality of communication services after newborn screening.
