Further Defining the Role of the Laboratory Genetic Counselor

ASCP explores the cancer biomarker testing navigator as a novel role to improve laboratory operations and workflows: A special report from the ASCP Biomarker Testing Navigator Project Team

OBJECTIVE

Cancer biomarker testing is a critical element in precision oncology, guiding treatment decisions and improving patient outcomes. However, the complexity and variability of biomarker testing processes present significant challenges for cancer centers, often leading to delays and inefficiencies that can compromise care quality. The American Society for Clinical Pathology explored the concept of a novel laboratory professional role: the cancer biomarker testing navigator (BTN).

METHODS

This study explored the feasibility and impact of the BTN role on laboratory operations and workflows through a 3-phase project consisting of a quantitative needs assessment, qualitative focus group discussions, and a short-term feasibility pilot conducted at 2 cancer centers.

RESULTS

The needs assessment revealed that many laboratories lack dedicated staff for coordinating biomarker testing, leading to operational inefficiencies. The roundtable discussions highlighted common challenges in biomarker testing and identified potential benefits of the BTN role, such as improved communication, better tracking of send-out tests, and enhanced task efficiency. The feasibility pilot demonstrated that BTNs could coordinate multigene next-generation sequencing panels and expedite key steps to ensure optimal preanalytical processes, reduce delays in testing, and smooth operations. The BTN role represents a feasible and beneficial addition to pathology laboratories that addresses key operational challenges in cancer biomarker testing and offers a promising solution to streamline laboratory operations, improve multidisciplinary communication, and enhance patient care coordination.

CONCLUSIONS

Further exploration is warranted to refine the BTN role and assess its long-term sustainability in and impact on diverse laboratory settings.

The impact of genetic counselor involvement in genetic and genomic test order review: A scoping review

PURPOSE

The increasing complexity of genetic technologies paired with more genetic tests being ordered by nongenetic health care providers, has resulted in an increase in the number of inappropriately ordered tests. Genetic counselors (GCs) are ideally suited to assess the appropriateness of a genetic test.

METHODS

We performed a scoping review of GC involvement in utilization management initiatives in order to describe the impact of having GCs involved in this process. Five databases (MEDLINE, EMBASE, CINHAL, EBM reviews, and Web of Science Core Collection) and gray literature were searched. We considered literature published in English since 2010.

RESULTS

A total of 51 studies were included. The most commonly evaluated outcomes included cancellation rate, economic efficiencies, impact on medical management, diagnostic rate, and time or triage efficiencies. Several studies also described GC impact on nongenetic health care providers.

CONCLUSION

Employment of GCs in the laboratory has been implemented widely as a solution to test misordering. These studies describe ways in which GCs can be integrated into testing workflows to reduce the number of inappropriate tests and have wider impacts on nongenetic health care providers' ordering practices and the patient experience.

Genetic counselor roles in the undiagnosed diseases network research study: Clinical care, collaboration, and curation

Genetic counselors (GCs) are increasingly filling important positions on research study teams, but there is limited literature describing the roles of GCs in these settings. GCs on the Undiagnosed Diseases Network (UDN) study team serve in a variety of roles across the research network and provide an opportunity to better understand genetic counselor roles in research. To quantitatively characterize the tasks regularly performed and professional fulfillment derived from these tasks, two surveys were administered to UDN GCs in a stepwise fashion. Responses from the first, free-response survey elicited the scope of tasks which informed development of a second structured, multiple-select survey. In survey 2, respondents were asked to select which roles they performed. Across 19 respondents, roles in survey 2 received a total of 947 selections averaging approximately 10 selections per role. When asked to indicate what roles they performed, respondent selected a mean of 50 roles (range 22-70). Survey 2 data were analyzed via thematic coding of responses and hierarchical cluster analysis to identify patterns in responses. From the thematic analysis, 20 non-overlapping codes emerged in seven categories: clinical interaction and care, communication, curation, leadership, participant management, research, and team management. Three themes emerged from the categories that represented the roles of GCs in the UDN: clinical care, collaboration, and curation. Cluster analyses showed that responses were more similar among individuals at the same institution than between institutions. This study highlights the ways GCs apply their unique skill set in the context of a clinical translational research network. Additionally, findings from this study reinforce the wide applicability of core skills that are part of genetic counseling training. Clinical literacy, genomics expertise and analysis, interpersonal, psychosocial and counseling skills, education, professional practice skills, and an understanding of research processes make genetic counselors well suited for such roles and poised to positively impact research experiences and outcomes for participants.

Analysis of the reported use of practice-based competencies by North American genetic counselors during the COVID-19 pandemic

Genetic counseling services changed due to the COVID-19 pandemic. Many genetic counselors (GCs) moved from in-person to telehealth services. Others were redeployed by choice or necessity, using their expertise to provide COVID-19 care and education. For some, their employment status changed due to budgetary constraints or decreasing referrals. This study surveyed North American GCs to assess the relative use of genetic counseling Practice-Based Competencies (PBCs) as a proxy for the skills used during the first wave of the pandemic, whether GCs were in their current role or in new or adjusted roles. A secondary aim was to determine whether GCs believe their training should be refocused in view of the workforce shifts posed by the pandemic. The survey comprised closed- and open-ended questions and was completed in full by 97 respondents. The study population was representative of the general genetic counseling workforce in terms of gender, race/ethnicity, age, and practice area when compared to the National Society of Genetic Counselors 2020 Professional Status Survey. Most participants (97.9%) indicated that the COVID-19 pandemic resulted in a change to their work, and 89.7% used at least one PBC at a different frequency than before the pandemic. The most significant change was the adaptation of genetic counseling skills for varied service delivery models: 83.5% of respondents indicated that their roles and responsibilities moved to a remote setting and/or utilized telehealth. The majority of participants felt competent using the PBCs during the pandemic. Major themes that emerged from the qualitative data were as follows: (a) adaptation of service delivery, (b) translation of genetic counseling skills, and (c) provision of psychosocial support. This study highlights practice changes for GCs due to the COVID-19 pandemic as well as the increased use of, and need for focused training in, varied service delivery models.

Adapting skills from genetic counseling to wearables technology research during the COVID-19 pandemic: Poised for the pivot

Genetic counselors have shown themselves to be adaptable in an evolving profession, with expansion into new sub-specialties, various non-clinical settings, and research roles. The COVID-19 pandemic caused a sudden and drastic shift in healthcare priorities. In an effort to contribute meaningfully to the COVID-19 crisis, and to adapt to a remote- and essential-only research environment, our workplace and thus our roles pivoted from genomics research to remote COVID-19 research using wearables technologies. With a deep understanding of genomic data, we were quickly able to apply similar concepts to wearables data including considering privacy implications, managing uncertain findings, and acknowledging the lack of ethnic diversity in many datasets. By sharing our own experience as an example, we hope individuals trained in genetic counseling may see opportunities for adaptation of their skills into expanding roles.

Genetic counseling student rotations in industry: How COVID-19 magnified the urgency for virtual learning options in diverse training settings

The COVID-19 pandemic created unprecedented challenges worldwide that required rapid adaptation and transformation across the entire healthcare system. Graduate medical training programs across all specialties have moved to rapidly adjust to the virtual landscape. This created a unique opportunity for genetic counselors who work in industry and within diagnostic laboratories to develop internship and rotation programs that can be offered virtually to meet the needs of genetic counseling training programs. Myriad Genetics, Inc., was contacted by numerous graduate programs in genetic counseling beginning in March 2020 requesting the opportunity for their students to participate in remote laboratory-based rotations. As a result of these requests, a working group of genetic counselors across Myriad came together to adapt existing experiences to fully remote formats and develop new remote-based opportunities for students. We describe our experience of expanding genetic counseling student rotations during the COVID-19 pandemic with the goal of providing examples of remote learning experiences that may be applicable to other diagnostic laboratory industry-based rotations for genetic counseling students. In 2020, a total of 59 second-year genetic counseling students, from 21 different genetic counseling training programs, participated in one of five different virtual experiences. Furthermore, two new rotation experiences were created to increase capacity and highlight diversity of industry roles. Genetic counselors in industry are uniquely positioned to provide both remote training opportunities for genetic counseling students and exposure to the variety of roles that genetic counselors can occupy. Increasing the exposure to these roles is important as the genetic counseling workforce continues to expand and diversify, and it is imperative among all programs to enable access to these opportunities.

The genetic counselor's role in management of patients with dyslipidemia

PURPOSE OF REVIEW

The role of genetic testing in diagnosis and management of dyslipidemias continues to grow. Consequently, it is increasingly important for patients to have access to clinicians who have expertise in medical genetics and the psychological implications related to this type of testing. Often a lipidologist has had limited training in this regard, and this review explores the role of the genetic counselor to fill this gap.

RECENT FINDINGS

Genetic counselors are key members of the healthcare team, and their specialized training in medical genetics and counseling allows them to fill this professional knowledge gap within the lipid clinic.

SUMMARY

With the continued emphasis on precision medicine, the utility of genetic testing for dyslipidemias will continue to grow. This will in turn increase the demand for provider expertise in medical genetics and counseling around these complex issues. Integrating a genetic counselor within the lipid clinic provides an ideal management scenario providing patients and families with access to not only medical information but also emotional support regarding their hereditary condition.

The current landscape of genetic test stewardship: A multi-center prospective study

Genetic counselors (GCs) play a pivotal role in selecting clinically appropriate and cost-effective genetic testing. Several single-institution reports over the past decade provide evidence of the value GCs bring to this stewardship role across diverse settings in healthcare, including hospital laboratories, commercial laboratories, and insurance companies. This multi-center, prospective, and quantitative study describes the outcomes of GC review of genetic test requests over a four-week period at six hospital laboratories and three commercial laboratories, thus expanding our understanding of this emerging specialty in the genetic counseling field. This study also highlights the added value of utilizing GC expertise in stewardship efforts, namely selecting the most appropriate genetic testing and realizing significant cost savings. GC review of genetic test requests led to an average order modification rate of 22%-25%. It also resulted in significant cost savings to institutions. The projected average annual savings after GC review of genetic test requests approximated $665,600 for hospital laboratories and $1,651,000 for commercial laboratories. These study findings demonstrate the significant value of GC-led genetic test stewardship programs, allow for comparisons across institutions currently performing genetic test stewardship, and support the implementation of a GC-led stewardship program at institutions who currently do not have one.

Characterization of genetic counselor practices in inpatient care settings

Rapid genomic testing is increasingly used in inpatient settings for diagnostic and treatment purposes. With the expansion of genetic testing in this setting, requests for inpatient genetics consultations have increased. There have been reports of genetic counselors working in inpatient care, though their specific roles are not well described. In this study, we characterized the roles of genetic counselors practicing in inpatient care settings in the United States and Canada. Genetic counselors were recruited via professional organization listservs to complete an online survey. The survey gathered information on participants' roles and workflow of inpatient genetics consultation services at their institution. Responses from 132 participants demonstrate that 50.4% of genetic counselors cover genetics consultations as needed or on a rotating schedule (34.6%). They practice in general pediatric (59.1%), neonatal (42.5%), cancer (28.3%), and/or prenatal (18.9%) specialties, among others. Participants reported working independently (16.1%) or with other providers (54.8%), including geneticists and other attending physicians. The workflow of genetics consultation services varies between institutions in the delivery of consults, members of the inpatient genetics consultation care team, and administrative support. Fifty percent of participants reported having no exposure to inpatients during graduate training, and 87.3% of participants reported receiving no institutional training for their inpatient role. This is the first study to describe roles of genetic counselors in inpatient care. It establishes a foundation for future research on inpatient genetic counseling and genetic counseling outcomes in inpatient services. As demand for genetics expertise in inpatient care grows, genetic counselors can be hired to serve inpatient populations alongside genetics and non-genetics providers.

Evolving Roles of Genetic Counselors in the Clinical Laboratory

Genetic counselors (GCs) possess several core competencies that provide direct benefit in the clinical laboratory setting. Communication with clients about complex information such as test methodology or results and the skills of facilitation and translation of complex information were recognized as important skills early in the establishment of GCs in laboratories. The clinical expertise of GCs serves as the background and experience from which they facilitate complex laboratory cases. Early roles for GCs in the laboratory also included result reporting, case management, and test development. The scope of roles has broadened to include management, business development, education, telemedicine, research, and variant interpretation. With increasing value being placed on genetic counseling skills both in and outside of a clinical laboratory, the roles and positions of GCs will likely continue to expand.

The composition and capacity of the clinical genetics workforce in high-income countries: a scoping review

As genetics becomes increasingly integrated into all areas of health care and the use of complex genetic tests continues to grow, the clinical genetics workforce will likely face greatly increased demand for its services. To inform strategic planning by health-care systems to prepare to meet this future demand, we performed a scoping review of the genetics workforce in high-income countries, summarizing all available evidence on its composition and capacity published between 2010 and 2019. Five databases (MEDLINE, Embase, PAIS, CINAHL, and Web of Science) and gray literature sources were searched, resulting in 162 unique studies being included in the review. The evidence presented includes the composition and size of the workforce, the scope of practice for genetics and nongenetics specialists, the time required to perform genetics-related tasks, case loads of genetics providers, and opportunities to increase efficiency and capacity. Our results indicate that there is currently a shortage of genetics providers and that there is a lack of consensus about the appropriate boundaries between the scopes of practice for genetics and nongenetics providers. Moreover, the results point to strategies that may be used to increase productivity and efficiency, including alternative service delivery models, streamlining processes, and the automation of tasks.

Variant interpretation is a component of clinical practice among genetic counselors in multiple specialties

PURPOSE

Genomic testing is routinely utilized across clinical settings and can have significant variant interpretation challenges. The extent of genetic counselor (GC) engagement in variant interpretation in clinical practice is unknown. This study aimed to explore clinical GCs' variant interpretation practice across specialties, understand outcomes of this practice, and identify resource and educational needs.

METHODS

An online survey was administered to National Society of Genetic Counselors members providing clinical counseling.

RESULTS

Respondents (n = 239) represented all major clinical specialties. The majority (68%) reported reviewing evidence documented by the laboratory for most (>60%) variants reported; 45.5% report seeking additional evidence. Prenatal GCs were less likely to independently assess reported evidence. Most respondents (67%) report having reached a different conclusion about a variant's classification than the testing laboratory, though infrequently. Time was the most commonly reported barrier (72%) to performing variant interpretation, though the majority (97%) indicated that this practice had an important impact on patient care. When presented with three hypothetical scenarios, evidence typically used for variant interpretation was generally applied correctly.

CONCLUSION

This study is the first to document variant interpretation practice broadly across clinical GC specialties. Our results suggest that variant interpretation should be considered a practice-based competency for GCs.

An exploration of novice genetic counselors' transitional challenges: Commencement is just the beginning

Although transitional challenges exist in many professions, no research has explicitly investigated challenges novice genetic counselors encounter as they enter the workforce. This qualitative study explored challenges genetic counselors face when transitioning from student to practicing counselor and their strategies for managing them. Fifteen novice genetic counselors (~1-2 years post-degree experience), recruited via the National Society of Genetic Counselors, participated in semi-structured phone interviews. Interview questions explored professional and personal challenges faced in their first 6 months, how challenges changed over time, strategies they used to manage these challenges, and resources they thought would have been helpful to have from the beginning. Inductive analysis of interview data yielded themes including: interpersonal challenges with colleagues (e.g. handling differences of opinion); intrapersonal challenges (e.g. lacking confidence, not feeling ready to 'go solo'); patient care challenges (e.g. being viewed as young/inexperienced); and logistical challenges (e.g. billing). Personal challenges included moving to a new location, preparing for boards, establishing a work-life balance, and factors associated with one's significant others. Strategies to address challenges included seeking support and guidance from experienced genetic counselors and peers, using peer supervision groups, and involvement in community activities. Participants recommended connecting with recent graduates through national and local programs to facilitate the transition from student to genetic counselor. Results suggest the 'transition years' pose a variety of professional and personal challenges. Support and guidance are key to evolving from student to practicing counselor. Creating venues to help novice counselors make connections with colleagues and other recent graduates may be beneficial.

Developing a genomics rotation: Practical training around variant interpretation for genetic counseling students

With the wide adoption of next-generation sequencing (NGS)-based genetic tests, genetic counselors require increased familiarity with NGS technology, variant interpretation concepts, and variant assessment tools. The use of exome and genome sequencing in clinical care has expanded the reach and diversity of genetic testing. Regardless of the setting where genetic counselors are performing variant interpretation or reporting, most of them have learned these skills from colleagues, while on the job. Though traditional, lecture-based learning around these topics is important, there has been growing need for the inclusion of case-based, experiential training of genomics and variant interpretation for genetic counseling students, with the goal of creating a strong foundation in variant interpretation for new genetic counselors, regardless of what area of practice they enter. To address this need, we established a genomics and variant interpretation rotation for Stanford's genetic counseling training program. In response to changes in the genomics landscape, this has now evolved into three unique rotation experiences, each focused on variant interpretation in the context of various genomic settings, including clinical laboratory, research laboratory, and healthy genomic analysis studies. Here, we describe the goals and learning objectives that we have developed for these variant interpretation rotations, and illustrate how these concepts are applied in practice.

An examination of the factors contributing to the expansion of subspecialty genetic counseling

In recent years, genetic counselors have moved into increasingly varied areas of patient care. Yet limited information is known about how these genetic counselors transitioned from more general clinical practice to subspecialized practice. This study was designed to answer three research questions: (1) What common factors establish a need for a genetic counselor in a subspecialty setting? (2) How do genetic counselors in subspecialties establish their positions? (3) Once established, how do the positions of these genetic counselors evolve as the subspecialty expands? Phone interviews with subspecialized genetic counselors led to the development of an online survey distributed through the National Society of Genetic Counselors ListServ. Sixty-eight of the 144 initial participants met eligibility criteria for participation as subspecialty genetic counselors in a clinical role. Physician interest in hiring a genetic counselor, clinical need, genetic counselor interest in subspecialty area, and available genetic testing were commonly reported as contributing factors to position creation. Most subspecialty genetic counseling positions were created as new positions, rather than evolved from a previous position. Over time, subspecialty positions drew more departmental funding and included increased clinical coordination or administrative responsibilities. The results of this study can encourage genetic counselors to collaborate with their medical institutions to utilize their skill-set in diverse areas of patient care.

Genetic counselling in the era of genomic medicine

BACKGROUND

Genomic technology can now deliver cost effective, targeted diagnosis and treatment for patients. Genetic counselling is a communication process empowering patients and families to make autonomous decisions and effectively use new genetic information. The skills of genetic counselling and expertise of genetic counsellors are integral to the effective implementation of genomic medicine.

SOURCES OF DATA

Original papers, reviews, guidelines, policy papers and web-resources.

AREAS OF AGREEMENT

An international consensus on the definition of genetic counselling. Genetic counselling is necessary for implementation of genomic medicine.

AREAS OF CONTROVERSY

Models of genetic counselling.

GROWING POINTS

Genomic medicine is a growing and strategic priority for many health care systems. Genetic counselling is part of this.

AREAS TIMELY FOR DEVELOPING RESEARCH

An evidence base is necessary, incorporating implementation and outcome research, to enable health care systems, practitioners, patients and families to maximize the utility (medically and psychologically) of the new genomic possibilities.

Readability of informed consent forms for whole-exome and whole-genome sequencing

Whole-exome and whole-genome sequencing (WES, WGS) can generate an unprecedented amount of complex information, making the informed consent (IC) process challenging. The aim of our study was to assess the readability of English IC forms for clinical whole-exome and whole-genome sequencing using the SMOG and Flesch-Kincaid formulas. We analysed 36 forms, most of which were from US providers. The median readability grade levels were 14.75 (the SMOG formula) and 12.2 (the Flesch-Kincaid formula); these values indicate the years of education after which a person would be able to understand a text studied. All forms studied seem to fail to meet the average recommended readability grade level of 8 (e.g. by Institutional Review Boards of US medical schools) for IC forms, indicating that the content of the forms may not be comprehensible to many patients. The sections aimed at health care professionals (HCPs) in the forms indicate that HCPs should be responsible for explaining IC information to the patients. However, WES and WGS may be increasingly offered by primary care professionals who may not (yet) have sufficient training to be able to communicate effectively with patients about genomics. Therefore, to secure an adequate, truly informed consent process, the task of developing good, legible examples of IC forms along with educating HCPs in genomics should be taken seriously, and adequate resources should be allocated to enable these tasks.

A Commentary on Opportunities for the Genetic Counseling Profession through Genomic Variant Interpretation: Reflections from an Ex-Lab Rat

The genetic counseling profession continues to expand and respond to the changing landscape of genomic medicine. "Non-traditional" genetic counseling roles have become more commonplace and the transferability of the genetic counselor skill set has been widely acknowledged, particularly in genetic laboratory settings. As these expanding roles continue to mature, all genetic counselors can benefit by learning and adopting clinically relevant skills, such as genomic variant interpretation, which can be applied to direct patient care. These skills can enrich our patients' understanding of their test results, help ensure quality patient care, and could be useful in positioning genetic counselors as critical members in the medical team as we continue to fully transition into the genomic medicine era.

A Commentary on Commercial Genetic Testing and the Future of the Genetic Counseling Profession

Commercial genetic testing laboratories are increasingly employing genetic counselors. As a result, the role of these or many genetic counselors is shifting from primarily direct patient counseling in clinics and hospitals to more laboratory-centered activities that involve case coordination, customer liaison, variant classification, marketing, and sales. Given the importance of these commercial entities to the genetic counseling profession, this commentary examines the current financial situation of four publicly traded, genetic testing companies. It also explores how the various roles of genetic counselors are likely to be affected by the financial pressures these companies face.

Movement of Genetic Counselors from Clinical to Non-clinical Positions: Identifying Driving Forces

A previous study of genetic counselors (GCs) in the state of Indiana identified movement out of clinical positions within the past 2 years. The aims of this study were to determine if this trend is nationwide and identify reasons why GCs are leaving their positions and factors that might help employers attract and retain GCs. An email was sent to members of the American Board of Genetic Counseling with a link to an online confidential survey. There were 939 responses (23.5% response rate). Overall, 52% of GCs report being highly satisfied in their current position, although almost two thirds think about leaving and one third had changed jobs within the past 2 years. Of those who had changed jobs (n = 295), 74.9% had been working in a hospital/clinic setting but only 46.3% currently do, demonstrating a major shift out of the clinic (p < 0.001). The top three reasons cited for leaving a position were work environment/institutional climate, salary/benefits, and a lack of feeling valued/recognized as a professional. These results confirm that GCs are moving out of clinical positions and document elements of job satisfaction. We suggest points for employers to consider when trying to recruit or retain GCs.

Direct-to-consumer genetic testing: where and how does genetic counseling fit?

Direct-to-consumer genetic testing for disease ranges from well-validated diagnostic and predictive tests to 'research' results conferring increased risks. While being targeted at public curious about their health, they are also marketed for use in reproductive decision-making or management of disease. By virtue of being 'direct-to-consumer' much of this testing bypasses traditional healthcare systems. We argue that direct-to-consumer genetic testing companies should make genetic counseling available, pre- as well as post-test. While we do not advocate that mandatory genetic counseling should gate-keep access to direct-to-consumer genetic testing, if the testing process has the potential to cause psychological distress, then companies have a responsibility to provide support and should not rely on traditional healthcare systems to pick up the pieces.
