Creation and beta testing of a "choose your own adventure" digital simulation to reinforce motivational interviewing skills in genetic counseling.

Standardized patients and/or role-playing are commonly used for practicing genetic counseling (GC) skills. Use of digital simulation, incorporating gamification elements, would require fewer resources to sustain than standardized patients. This manuscript reports steps taken and the lessons learned from creating a digital "Choose your own adventure" simulation in which students select preferred dialog for a genetic counselor who is seeing an adult patient to discuss genetic testing for the known pathogenic variant that caused familial adenomatous polyposis (FAP) in their father. The case has three endings, one of which is attained by selecting options that are mostly consistent with motivational interviewing counseling techniques. We conducted a preliminary evaluation of our beta version among nine GC students and one educator using a survey to assess acceptability and appropriateness as well as to elicit open-ended feedback. All participants agreed or strongly agreed with statements indicating the case was acceptable, appropriate, and fun. Users particularly appreciated the immediate feedback given throughout the case simulation. Many users wanted more options to select from and listed various other recommendations, including several which would require substantial resources to implement.

Factors that differentiate cancer risk management decisions among females with pathogenic/likely pathogenic variants in PALB2, CHEK2, and ATM.

PURPOSE: Following disclosure of pathogenic or likely pathogenic variants in hereditary cancer genes, patients face cancer risk management decisions. Through this mixed-methods study, we investigated cancer risk management decisions among females with pathogenic or likely pathogenic variants in PALB2, CHEK2, and ATM to understand why some patients follow National Comprehensive Cancer Network guidelines, whereas others do not. METHODS: Survey and interview data were cross-analyzed using a 3-stage approach. Identified factors were used to conduct coincidence analysis and differentiate between combinations of factors that result in following or not following guidelines. RESULTS: Of the 13 participants who underwent guideline inconsistent prophylactic surgery, 12 fit 1 of 3 unique patterns: (1) cancer-related anxiety in the absence of trust in care, (2) provider recommending surgery inconsistent with National Comprehensive Cancer Network guidelines, or (3) surgery occurring before genetic testing. Two unique patterns were found among 18 of 20 participants who followed guidelines: (1) anxiety along with trust in care or (2) lack of anxiety and no prophylactic surgery before testing. CONCLUSION: Health care provider recommendations and trust in care may influence whether individuals receive care that is congruent with risk levels conferred by specific genes. Interventions are needed to improve provider knowledge, patient trust in non-surgical care, and patient anxiety.

Healthcare decision makers' perspectives on the creation of new genetic counselor positions in North America: Exploring the case for psychiatric genetic counseling.

Mental illnesses are common and highly heritable. Patients and their families want and benefit from receiving psychiatric genetic counseling (pGC). Though the pGC workforce is among the smallest of genetic counseling (GC) specialties, genetic counselors (GCs) want to practice in this area. A major barrier to the expansion of the pGC workforce is limited availability of advertised positions, but it remains unclear why this is the case. We used a qualitative approach to explore drivers for and barriers to the creation of GC positions (including pGC) at large centralized genetic centers in the United States and Canada that offer multiple specialty GC services. Individuals with responsibilities for making decisions about creating new clinical GC positions were interviewed using a semi-structured guide, and an interpretive description approach was used for inductive data analysis. From interviews with 12 participants, we developed a theoretical model describing how the process of creating new GC positions required institutional prioritization of funding, which was primarily allocated according to physician referral patterns, which in turn were largely driven by availability of genetic testing and clinical practice guidelines. Generating revenue for the institution, improving physician efficiency, and reinforcing institutional mission were all regarded as valued outcomes that bolstered prioritization of funding for new GC positions. Evidence of patient benefit arising from new GC positions (e.g., pGC) seemed to play a lesser role. These findings highlight the tension between how institutions value GC (generating revenue, reacting to genetic testing), and how the GC profession sees its value (providing patient benefit, focus on counseling).

Knowledge and perceptions of the genetic counseling profession among a national cross-sectional sample of U.S. adults.

Awareness of the genetic counseling (GC) profession may influence access to genetic services, yet awareness among the U.S. population is unknown. A survey of U.S. adults was conducted using age- and sex-based quotas. Participants were asked if they had heard of the GC profession and to describe what genetic counselors (GCs) do. After reading a brief description of what GCs do, participants were asked the likelihood they would request to see a genetic counselor if they were concerned about a genetic condition. We used descriptive statistics to characterize the population, logistic regression to determine factors related to awareness of the GC profession, and ordinary least squares regression to identify which factors correlated with likelihood of seeking GC services. Thematic analysis was used to code open-ended responses. Among the final sample of 543, the majority were White individuals (79.7%) with an average age of 46.5 and median income between $60,000 and $69,999. Although 20% indicated they had heard of the GC profession, further analysis of the qualitative follow-up question suggested only 13.4% understood the role of GCs (CI 10.6%-16.3%). Factors positively and significantly correlated with knowledge of the GC profession included identifying as White or female and having higher educational attainment or higher science knowledge after controlling for income, age, and political views. Approximately 45% of respondents indicated they would likely or very likely seek GC if concerned about a genetic condition. Biological sex, age, religious affiliation, science knowledge, and awareness of the GC profession were significantly correlated with likelihood of seeking GC services while controlling for race, income, educational attainment, and political views. Curiosity/interest, the perception of benefits, and trust in GCs were all major themes that emerged to explain reasons for seeking an appointment with GCs. Lack of awareness, lack of perceived benefit, and lack of trust in GCs or greater trust in other healthcare providers were reasons for not wanting a GC appointment. Despite the 50-year existence of the GC profession, awareness remains low and negative attitudes exist.

Proposed outcomes measures for state public health genomic programs.

PURPOSE: To assess the implementation of evidence-based genomic medicine and its population-level impact on health outcomes and to promote public health genetics interventions, in 2015 the Roundtable on Genomics and Precision Health of the National Academies of Sciences, Engineering, and Medicine formed an action collaborative, the Genomics and Public Health Action Collaborative (GPHAC). This group engaged key stakeholders from public/population health agencies, along with experts in the fields of health disparities, health literacy, implementation science, medical genetics, and patient advocacy. METHODS: In this paper, we present the efforts to identify performance objectives and outcome metrics. Specific attention is placed on measures related to hereditary breast ovarian cancer (HBOC) syndrome and Lynch syndrome (LS), two conditions with existing evidence-based genomic applications that can have immediate impact on morbidity and mortality. RESULTS: Our assessment revealed few existing outcome measures. Therefore, using an implementation research framework, 38 outcome measures were crafted. CONCLUSION: Evidence-based public health requires outcome metrics, yet few exist for genomics. Therefore, we have proposed performance objectives that states might use and provided examples of a few state-level activities already under way, which are designed to collect outcome measures for HBOC and LS.

Evaluation of a theory-driven e-learning intervention for future oral healthcare providers on secondary prevention of disordered eating behaviors.

Oral healthcare providers have a clinical opportunity for early detection of disordered eating behaviors because they are often the first health professionals to observe overt oral and physical signs. Curricula regarding early recognition of this oral/systemic medical condition are limited in oral health educational programs. Web-based learning can supplement and reinforce traditional learning and has the potential to develop skills. The study purpose was to determine the efficacy of a theory-driven Web-based training program to increase the capacity of oral health students to perform behaviors related to the secondary prevention of disordered eating behaviors. Using the Reach, Effectiveness, Adoption, Implementation and Maintenance evaluation framework, a longitudinal group-randomized controlled trial involving 27 oral health classes from 12 oral health education programs in the United States was implemented to assess the efficacy of the Web-based training on attitudes, knowledge, self-efficacy and skills related to the secondary prevention of disordered eating behaviors. Mixed-model analysis of covariance indicated substantial improvements among students in the intervention group (effect sizes: 0.51-0.83) on all six outcomes of interest. Results suggest that the Web-based training program may increase the capacity of oral healthcare providers to deliver secondary prevention of disordered eating behaviors. Implications and value of using the Reach, Effectiveness, Adoption, Implementation and Maintenance framework are discussed.

Applying the framework for developing and evaluating complex interventions to increase family communication about hereditary cancer.

Objective: Evaluate an intervention to increase family communication (FC) of positive hereditary cancer test results using the Framework for Developing and Evaluating Complex Interventions (FDECI). Methods: We developed 'programme theory' during the FDECI development phase by aligning intervention components with behavior change techniques (BCTs) and theoretical factors expected to improve FC. During the feasibility phase, we obtained feedback from 12 stakeholder interviews. Results: Intervention components aligned with a total of 14 unique BCTs for which prior evidence links the BCT to theoretical factors that influence behavior change. Constructive stakeholder feedback included: more information desired, rewording to support autonomy by highlighting options, and improvements to navigation, visuals, and audio. Positive comments included: comprehensiveness of materials, modeling of conversations, and usefulness of the materials for helping a person prepare to share positive test results. Conclusion: The first FDECI phases were helpful for improving the intervention and planning our ongoing effectiveness and future implementation phases. Innovation: Our application of the FDECI is novel, including plans to test our 'programme theory' using coincidence analysis (CNA) to determine who accesses which intervention materials, how utilizing certain materials impact the aligned theoretical factors, and whether these in turn make a difference in the behavioral outcome.

DiGeorge anomaly in the absence of chromosome 22q11.2 deletion.

OBJECTIVE: To test the hypothesis that the prevalence of deletion 22q11.2 among individuals who meet criteria for DiGeorge anomaly (DGA) is lower than the 90% commonly cited. STUDY DESIGN: Participants were identified through retrospective chart reviews on all patients who underwent testing for deletion 22q11.2 and all patients with a diagnosis of "DiGeorge" or any of the major criteria associated with DGA at a large pediatric hospital over a period of 6 years. DGA was confirmed in 64 individuals, based on the presence of at least 2 of the following features: (1) cellular immune deficiency and/or absence of part or all of the thymus; (2) hypocalcemia and/or parathyroid deficiency; (3) congenital heart disease. RESULTS: Of the 64 individuals with DGA, 29 (45%) did not have a chromosome 22q11.2 deletion. Among this deletion-negative subset, diabetic embryopathy and other chromosome abnormalities were the most commonly recognized underlying etiologies. CONCLUSIONS: These findings challenge a widely held belief that nearly 90% of DGA is due to chromosome 22q11.2 deletion. This study also calls attention to the heterogeneity of DGA, highlights similarities and differences between those with and without a chromosome 22q11.2 deletion, and attempts to resolve some confusing features of conditions associated with DGA.

Views on abortion: a comparison of female genetic counselors and women from the general population.

While literature characterizing individual genetic counselors' abortion attitudes is sparse, the National Society of Genetic Counselors takes a clear stance for reproductive autonomy. To determine genetic counselors' views, this study compared (1) genetic counselors' abortion attitudes to those of women from the general population and (2) genetic counselors' professional abortion attitudes to their personal abortion attitudes. Genetic counselors were invited to complete an online survey. Response rate was 44.3% (709/1,601). Compared to women from the general population, female genetic counselors were significantly more likely to agree abortion should be an option in all cases (p < .001). Controlling for other possible confounders, regression analyses revealed that being a genetic counselor, religious service attendance and age were significantly predictive of abortion attitudes. Although the vast majority of genetic counselors agree that abortion should be available, they are significantly less likely to personally consider abortion under all circumstances presented (p < .001), and the percentage of genetic counselors who would consider terminating in the case of a severe birth defect is similar to studies of other women.

Genetic counselors' religiosity & spirituality: are genetic counselors different from the general population?

Although there is evidence that the religious beliefs of genetic counselors (GCs) can induce internal conflict in at least some genetic counseling scenarios, empirical research on the religiosity of GCs is limited. This study compares genetic counselors to a representative sample of the adult U.S. population on multiple religiosity measures. After controlling for several sociodemographic factors the percentage of GCs who report having a religious affiliation is similar to the general U.S., but GCs are less likely to affiliate with conservative Christian religions and are more likely to be Jewish. GCs are significantly less likely than the general U.S. population to: believe in god, attend religious services, pray, and believe in an afterlife even after controlling for relevant sociodemographic factors. Despite the lower levels of religiosity, a majority of GCs do report themselves to be moderately to highly spiritual. We explore potential reasons for religiosity differences as well as possible implications in the context of the GC scope of practice.

A success of a genetics educational intervention for nursing and dietetic students: A model for incorporating genetics into nursing and allied health curricula.

Allied health care professionals and nurses provide genetic-related client services, such as eliciting family medical history information and discussing the genetic component of health conditions. However, these professionals report a lack of confidence in their ability to perform genetic services and have little formal education in genetics. A barrier to incorporating genetics into allied health curricula includes the limited flexibility to expand curricula. This barrier was addressed by incorporating a Web-based tutorial on basic genetics and a lecture on the genetics of diabetes into preexisting undergraduate nutrition courses for nursing and dietetic students. The vast majority of students enrolled in these required courses participated in the intervention. Most participants agreed that genetics is important to their future career. Following the intervention, students' knowledge of genetics and confidence in their ability to provide genetic-related services increased significantly. Despite the short-term success and positive student evaluations, a single educational intervention does not appear to be sufficient for students to become proficient in performing the recommended genetic competencies for all health care professionals. Recommendations and resources for incorporating genetics into allied health curricula are included.

Developing and pretesting case studies in dental and dental hygiene education: using the diffusion of innovations model.

Case-based learning offers exposure to clinical situations that health professions students may not encounter in their training. The purposes of this study were to apply the Diffusion of Innovations conceptual framework to 1) identify characteristics of case studies that would increase their adoption among dental and dental hygiene faculty members and 2) develop and pretest interactive web-based case studies on sensitive oral-systemic health issues. The formative study spanned two phases using mixed methods (Phase 1: eight focus groups and four interviews; Phase 2: ten interviews and satisfaction surveys). Triangulation of quantitative and qualitative data revealed the following positive attributes of the developed case studies: relative advantage of active learning and modeling; compatibility with a variety of courses; observability of case-related knowledge and skills; independent learning; and modifiability for use with other oral-systemic health issues. These positive attributes are expected to increase the likelihood that dental and dental hygiene faculty members will adopt the developed case study once it is available for use. The themes identified in this study could be applied to the development of future case studies and may provide broader insight that might prove useful for exploring differences in case study use across dental and dental hygiene curricula.

Genotype-phenotype analysis in congenital adrenal hyperplasia due to P450 oxidoreductase deficiency.

CONTEXT: P450 oxidoreductase deficiency (PORD) is a unique congenital adrenal hyperplasia variant that manifests with glucocorticoid deficiency, disordered sex development (DSD), and skeletal malformations. No comprehensive data on genotype-phenotype correlations in Caucasian patients are available. OBJECTIVE: The objective of the study was to establish genotype-phenotype correlations in a large PORD cohort. DESIGN: The design of the study was the clinical, biochemical, and genetic assessment including multiplex ligation-dependent probe amplification (MLPA) in 30 PORD patients from 11 countries. RESULTS: We identified 23 P450 oxidoreductase (POR) mutations (14 novel) including an exonic deletion and a partial duplication detected by MLPA. Only 22% of unrelated patients carried homozygous POR mutations. p.A287P was the most common mutation (43% of unrelated alleles); no other hot spot was identified. Urinary steroid profiling showed characteristic PORD metabolomes with variable impairment of 17α-hydroxylase and 21-hydroxylase. Short cosyntropin testing revealed adrenal insufficiency in 89%. DSD was present in 15 of 18 46,XX and seven of 12 46,XY individuals. Homozygosity for p.A287P was invariably associated with 46,XX DSD but normal genitalia in 46,XY individuals. The majority of patients with mild to moderate skeletal malformations, assessed by a novel scoring system, were compound heterozygous for missense mutations, whereas nearly all patients with severe malformations carried a major loss-of-function defect on one of the affected alleles. CONCLUSIONS: We report clinical, biochemical, and genetic findings in a large PORD cohort and show that MLPA is a useful addition to POR mutation analysis. Homozygosity for the most frequent mutation in Caucasians, p.A287P, allows for prediction of genital phenotype and moderate malformations. Adrenal insufficiency is frequent, easily overlooked, but readily detected by cosyntropin testing.

Undetectable maternal serum uE3 and postnatal abnormal sterol and steroid metabolism in Antley-Bixler syndrome.

Antley-Bixler syndrome (ABS) is a rare condition characterized by radiohumeral synostosis, craniosynostosis, midface hypoplasia, bowing of the femora, multiple joint contractures, and urogenital defects. Several reports have implicated errors of steroid or sterol metabolism in the pathogenesis of ABS. Evidence for this has included association with maternal luteomas, fetal 21-hydroxylase deficiency, early pregnancy exposure to high-dose fluconazole, lanosterol 14-alpha-demethylase deficiency, and a unique urinary steroid profile consistent with apparent pregnene hydroxylation deficiency (APHD). We report two sibs with classic ABS. During both pregnancies, mid-trimester maternal serum screening demonstrated undetectable levels of uncongugated estriol (uE3). The brother had ambiguous genitalia and increased serum levels of progesterone and 17-alpha-hydroxyprogesterone. Postnatal tests performed on the sister demonstrated both the unique urinary steroid profile that defines APHD and evidence of impaired lanosterol 14-alpha-demethylase activity. Our results suggest that in at least some patients with ABS, the skeletal findings and altered steroidogenesis are not associated with genes specific to individual sterol or steroid pathways but rather are related to an element, such as NADPH cytochrome P450 reductase (CPR) or cytochrome b5 (CYb5), that is common to all of these pathways.

Biochemical diagnosis of Antley-Bixler syndrome by steroid analysis.

Antley-Bixler syndrome (ABS, MIM 207410) is a skeletal abnormality syndrome primarily affecting head and limbs. Little is known of the origin of the condition but inactivating mutations in the fibroblast growth factor receptor (FGFR2) has been found in some patients. Genital ambiguity is seen occasionally in this condition, suggesting possible disordered steroidogenesis in early pregnancy. We report the steroid excretion of eight patients diagnosed with the syndrome and one with a related condition, a mild phenotype of the disorder since skeletal and genital abnormalities were not evident. The steroid excretion pattern was consistent and very distinctive in all nine patients. Metabolites of the two primary precursors of steroid hormones, pregnenolone and progesterone, were elevated as were the classical diagnostic metabolites for 17- and 21-hydroxylase deficiencies. Cortisol production was typically within the normal range but generally had blunted response to ACTH. Androgen metabolite excretion tends to be low in patients over 2 months of age, but may be elevated in the newborn period. The metabolome suggested attenuated steroid hydroxylation (including 17,20-lyase activity) although underlying cause is yet to be established. Mutations in CYP17 and CYP21 have not been found and currently the prime suspect is an abnormality in an essential redox partner (P450 oxidoreductase). This paper proposes use of the distinctive steroid metabolome as the primary biochemical parameter for diagnosis of ABS, at least the form not associated with FGFR2 mutations.
