Coffee and Conversation: A Genuine Dialogue on Authentic Professional Learning Between Genetic Counselor Educators

5.12.2023

Lifelong learning is a term frequently referred to in the training and continuing professional development of genetic counselors. It implies the ability to continuously engage in self-motivated reflection to identify knowledge gaps and develop a learning plan to address identified needs or interests. In contrast to this definition, the path to continuing professional development for most genetic counselors involves attendance at conferences; yet much data suggest that other forms of learning are more effective at leading to practice change and improved patient or quality outcomes. These conflicting ideas beg the question: what is professional learning? A dialogue between two genetic counselor educators, both with advanced training in health professional education, shares personal beliefs regarding lifelong learning in the genetic counseling profession. This discourse represents an authentic conversation that was audio-recorded and transcribed with minimal editing to improve clarity and readability. The views presented in this dialogue are highly personal, yet grounded in educational theory. References are provided to those that desire further reading on the topics discussed. Several authentic learning strategies are described, including communities of practice, peer supervision, and personal learning projects. The authors consider ways to increase knowledge acquisition from conference attendance and discuss how learning on the job becomes embedded in practice. As a result of this discourse, the authors hope to inspire genetic counselors to reflect over their continuing professional development and consider their job as a learning environment that presents rich, ongoing, and unique opportunities for growth. The authors invite and challenge readers to identify learning needs and set goals for themselves to address those needs. For those with interest in education, it is hoped that the conversation sparks new or invigorated interest that will lead to novel or more effective learning opportunities with improved outcomes for patients, students, and colleagues alike.

Healthcare Decision Makers' Perspectives on the Creation of new Genetic Counselor Positions in North America: Exploring the case for Psychiatric Genetic Counseling

5.12.2023

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).

Psychiatric Genetic Counseling: A Survey of Australian Genetic Counselors' Practice and Attitudes

5.12.2023

Genetic counseling plays a critical role in supporting individuals and their families' adaption to psychiatric conditions, addressing the multifactorial nature of these conditions in a personally meaningful and empowering way. Yet data related to the practice and attitudes of Australian genetic counselors about psychiatric genetic counseling (PGC) is limited. This survey investigated the practice of Australian genetic counselors, and their attitudes toward PGC. Genetic counselors (N = 393) were invited to participate in an anonymous online survey between March and May 2022. Forty-four genetic counselors (response rate = 11%) from Australia and New Zealand responded. No respondents practice in psychiatric genetics as their speciality area; most respondents do not see any patients where the primary indication is a personal and/or family history of psychiatric disorders (91%). Greater than half of respondents (56%) believed there was sufficient evidence to support PGC, and 64% enquire about personal and/or family history of psychiatric disorders, but only 25% provide genetic counseling on this topic. Most respondents do not feel confident providing risk assessments for psychiatric disorders (72%), while the majority expressed interest in attending specialist training (95%), and in incorporating PGC into future practice (77%). Australian genetic counselors would benefit from psychiatric genetic education and training, and establishment of specialized PGC services would address this gap in patient care, while providing opportunities for genetic counselors to gain skills and experience in PGC.

Exploring Parental Cystic Fibrosis Disclosure to Well Children

5.12.2023

Cystic fibrosis (CF), a genetic disease and chronic illness, affects multiple organ systems and requires exceptional medical care and treatment. Few studies have assessed the diagnosis disclosure process to well children when their sibling(s) have CF, and none have evaluated the association between parental knowledge of CF and the disclosure of CF. The objectives of this study were to assess parental understanding of CF, demonstrate the most commonly shared topics and their frequencies of discussion with well children, and identify associations between parental understanding of CF and aspects of the disclosure process to well children. Parents were recruited from CF support organizations and asked to complete an online, anonymous survey. Individuals were eligible to participate in the study if they had at least one living child with CF and at least one living child without CF. Completed surveys from 48 individuals revealed that most parents began discussing a sibling's diagnosis of CF with the first-born well child at 5.4 years old. Topics related to CF were discussed openly and as needed with their well children (n = 44). The most frequently discussed topic, and the topic ranked most important (1.93 of 5, SD: 1.17) by 40 participants (90.9%), was medical concerns and treatment for CF. Fewer parents (n = 18, 40.9%) reported discussing the financial impact of CF, and many ranked this as least important to share (4.64 of 5, SD: 0.75). The CF knowledge assessment revealed that participants were well-informed about CF, with a mean total score of 8.9/10 (SD: 0.91). There were no associations between CF knowledge assessment scores, education level, income, and the topics discussed with well children. These results can be utilized by genetic counselors and other healthcare specialists in discussion with parents about the disclosure process of a diagnosis of CF to well children.

BRCAShare—Assessment of an Animated Digital Message for Intrafamilial Communication of Pathogenic Variant Positive Test Results: A Feasibility Study

5.12.2023

While genetic testing for hereditary breast and ovarian cancer syndrome (HBOC) is well-established in the field of medicine, family members' uptake of cascade genetic testing for known familial pathogenic variants remains low. Probands often become responsible for initiating familial communication about their testing results, and barriers to communication may include difficulty in conveying information to relatives and a lack of communication resources for probands' use. In this study, we tested a two-minute animated digital message (ADM) intervention guided by the Health Belief Model (HBM) in an unselected sample to determine hypothetical individual perceptions of susceptibility and severity and behavioral intention to act on the information provided in the ADM. We recruited genetic testing naïve adults from the United States with no personal history of cancer through Amazon Mechanical Turk to participate in this study. Participants were presented a hypothetical scenario describing a relative's recent HBOC diagnosis, viewed the ADM, and answered a questionnaire assessing participants' perception of the HBM constructs in relation to the hypothetical scenario and participants' intentions to pursue cascade genetic testing, talk to a healthcare professional, or talk to family members after ADM viewing. Participants (n = 373) largely perceived HBOC as serious and believed that they could benefit from the information provided by genetic testing; 76% hypothetically intended to pursue genetic testing at a cost of $100 or less, and 90% intended to either pursue testing or talk to a healthcare provider or family members. This feasibility study in an unaffected population could mimic the experience of distant/less-engaged relatives in HBOC families after receiving unexpected information about cascade genetic testing. Most participants demonstrated behavioral intention toward cascade testing, at a rate higher than literature would suggest is typical in high-risk families, indicating that a theory-supported, simple to use intervention may be useful in clinical practice.

North American Genetic Counselors' Approach to Collecting and Using Ancestry in Clinical Practice

5.12.2023

Current guidelines from the National Society of Genetic Counselors (NSGC) recommend that patients' ancestry be obtained when taking a family history. However, no study has explored how consistently genetic counselors obtain or utilize this information. The goals of this study included assessing how genetic counselors collect their patients' ancestry, what factors influence this decision, and how they view the utility of this information. Genetic counselors working in a direct patient care setting in the US or Canada were recruited to participate in an anonymous survey via an NSGC email blast. Most participants (n = 115) obtain information about their patients' ancestry (96.5%), with the most common methods being directly asking the patient (91%) and utilizing intake forms (43.2%). Of participants who ask about ancestry directly, 50.5% always ask about the presence of Ashkenazi Jewish ancestry and 70.3% always ask about additional ancestries, suggesting that for most genetic counselors’ collection of ancestry is standard practice. However, the clinical utility of ancestry information is highly variable, with the impact on genetic testing choice being particularly low. A slight majority of participants support a reevaluation of current ancestry guidelines (51.3%), with many participants suggesting that the varying utility of ancestry in different clinical indications/specialties should be incorporated into guidelines. Despite being standard practice for most genetic counselors, no unified approach or standard for how ancestral information should be used in genetic counseling practice was identified.

Evaluating a Communication Aid for Return of Genetic Results in Families with Hypertrophic Cardiomyopathy: A Randomized Controlled Trial

5.12.2023

Genetic testing for hypertrophic cardiomyopathy (HCM) is considered a key aspect of management. Communication of genetic test results to the proband and their family members, can be a barrier to effective uptake. We hypothesized that a communication aid would facilitate effective communication, and sought to evaluate knowledge and communication of HCM risk to at-risk relatives. This was a prospective randomized controlled trial. Consecutive HCM patients attending a specialized clinic, who agreed to participate, were randomized to the intervention or current clinical practice. The intervention consisted of a genetic counselor-led appointment, separate to their clinical cardiology review, and guided by a communication booklet which could be written in and taken home. Current clinical practice was defined as the return of the genetic result by a genetic counselor and cardiologist, often as part of a clinical cardiology review. The primary outcome was the ability and confidence of the individual to communicate genetic results to at-risk relatives. The a priori outcome of improved communication among HCM families did not show statistically significant differences between the control and intervention group, though the majority of probands in the intervention group achieved fair communication (n = 13/22) and had higher genetic knowledge scores than those in the control group (7 ± 3 versus 6 ± 3). A total of 29% of at-risk relatives were not informed of a genetic result in their family. Communication among HCM families remains challenging, with nearly a third of at-risk relatives not informed of a genetic result. We show a significant gap in the current approach to supporting family communication about genetics. Australian New Zealand Clinical Trials Registry: ACTRN12617000706370.

Introduction of the Genetic Counseling Profession by Teachers in BIPOC-majority High Schools

5.12.2023

The field of genetic counseling is racially and ethnically (RE) homogenous, with 90% of genetic counselors identifying as white. As awareness of genetic counseling increases interest in the career, one proposed method to increase the profession's RE diversity is to introduce genetic counseling as a career option to Black, Indigenous, and people of color (BIPOC) students during high school. This study explores the knowledge, presentation, and perceptions of the genetic counseling profession by high school teachers at BIPOC-majority high schools in the United States (US). Science teachers working at public high schools in Massachusetts and New York where greater than 75% of the student body identifies as BIPOC were invited to participate in a survey and focus groups for this study. A total of 456 teachers participated in the survey and a total of seven teachers participated in two focus groups. The survey data revealed that most (91.8%) participating teachers presented genetic counseling, though BIPOC-identifying teachers were more likely to report never presenting genetic counseling than white-identifying teachers. In addition, teachers' knowledge of the genetic counseling career and frequency of presenting it were strongly associated, suggesting that increasing knowledge of genetic counseling among teachers, particularly those who are BIPOC-identifying, could lead to increased presentation to BIPOC students. Major themes that emerged through the focus groups included (1) teachers perceiving genetic counseling as novel and complex in comparison to other healthcare professions, (2) teachers sharing that multiple methods can and should be used when introducing genetic counseling to students, and (3) the notion that teachers could have an important role in introducing genetic counseling to their students. Considering findings from the survey and focus groups, recommendations from this study include increasing awareness of genetic counseling among BIPOC-identifying science teachers at BIPOC-majority high schools, gradually introducing genetic counseling topics to students beginning at a young age, and utilizing student-led teaching activities.

Clinical Geneticists' Views on and Experiences with Unsolicited Findings in next-generation Sequencing: “A Great Technology Creating New Dilemmas”

5.12.2023

Unsolicited findings (UFs) from diagnostic genetic testing are a subject of debate. The emerging consensus is that some UFs from genetic testing should be disclosed, but recommendations on UF disclosure generally leave room for variation in practice. This study aimed to explore clinical geneticists' views on and experiences with UFs during pretest counseling and UF disclosure. We interviewed 20 certified clinical genetics medical specialists and clinical genetics residents, working in 7 Dutch genetic centers. Participants indicated that discussing the probability of detecting UFs is an integral part of pretest counseling and informed consent. However, they expressed doubts about the degree to which this discussion should occur and about what information they should share with patients. They argued that the contents of their counseling should depend on the individual patient's capacity to understand information. These results endorse the importance of tailored pretest counseling alongside informed consent for optimal genetic consultations. While “medical actionability” is broadly accepted as an important criterion for the disclosure of UFs, participants experienced substantial uncertainty regarding this concept. This study underscores the need for further demarcation of what exactly constitutes medical actionability. Installation of an expert panel to help healthcare professionals decide what variants to disclose will support them when facing the dilemmas presented by UFs.

Australian Healthcare Professionals' Perspectives on the Ethical and Practical Issues Associated with Genomic Newborn Screening

5.12.2023

Newborn bloodspot screening (NBS) is a successful public health initiative that seeks to identify serious, treatable medical conditions. The increasing use of genomic sequencing (GS) in a wide range of medical settings has reignited the discussion on whether GS can and should be integrated into NBS. Yet, the perspectives of healthcare professionals (HCPs) in Australia on the ethical and practical issues associated with the implementation of genomic newborn screening (GNBS) are underexplored. To address this, we conducted semi-structured interviews with 16 Australian HCPs with clinical or policy experience in NBS and/or GS to explore their perspectives on the ethical, social, and practical issues raised by integrating GS into NBS. Interviews were analyzed using inductive content analysis. When asked whether GS should be incorporated into NBS, HCPs did not feel it was currently appropriate but there was a strong consensus it may be implemented within the next decade. However, HCPs had differing perspectives on what conditions should be included and how to best handle the volume of data generated from GNBS. Our findings have important implications for determining at what point and how genomics can be integrated into NBS. The differing views expressed amongst HCPs suggest that further research is needed to explore the reasons behind this. Importantly, our participants highlighted a potential role for genetic counselors in the implementation of GNBS on a larger scale by developing educational resources to facilitate obtaining informed consent and return of results.
