Expanding Roles: A Survey of Public Health Genetic Counselors

International genetic counseling: What do genetic counselors actually do?

We conducted an exploratory survey of genetic counselors internationally to assess similarities and differences in reported practice activities. Between November 2018 and January 2020 we conducted a mass emailing to an estimated 5600 genetic counselors in different countries and regions. We obtained 189 useable responses representing 22 countries, which are included in an aggregate manner. Data from countries with 10 or more responses, comprising 82% of the total (N = 156), are the primary focus of this report: Australia (13), Canada (26), USA (59), UK (17), France (12), Japan (19) and India (10). Twenty activities were identified as common (≥74%) across these countries, encompassing most subcategories of genetic counseling activity. Activities with most frequent endorsement include: reviewing referrals and medical records and identifying genetic testing options as part of case preparation; taking family and medical histories; performing and sharing risk assessment; and educating clients about basic genetic information, test options, outcomes and implications, including management recommendations on the basis of the test results. Genetic counselors also consistently establish rapport, tailor the educational process, facilitate informed decision making and recognize factors that may impact the counseling interaction. The least endorsed activities were in the Medical History category. Notable differences between countries were observed in the endorsement of 33 activities, primarily in the Contracting and Establishing Rapport, Family History, Medical History, Assessing Patients Psychosocially and Providing Psychosocial Support categories. Generalizations about international practice patterns are limited by the low response rate. However, this study is, to our knowledge, the first to systematically compare the clinical practice and specific activities of genetic counselors working in different countries.

The genetic counselor workforce in inherited retinal disease clinics: a descriptive assessment

BACKGROUND

Genetic counselors (GCs) have practiced in Inherited Retinal Disease (IRD) clinics for several decades. In this small subspecialty of genetic counseling, GCs are critical for patient understanding of genetic information, which can have prognostic, systemic, family planning and therapeutic implications. Recently, both access to genetic testing for IRDs and the number of genes associated with IRDs (>350) has increased dramatically. However, the practice models and roles of IRD GCs have not been previously described.

MATERIALS AND METHODS

GCs working in academic IRD clinics were surveyed to assess their experience, clinical practices, and roles performed. The collected data was compared to the broader genetic counseling profession and to other specialties using publicly available data on GC professional practices.

RESULTS

While roles of IRD GCs were overlapping with those of the overall genetic counseling profession, all survey respondents reported diverse roles that included both clinical and non-clinical duties, spending up to half their time on research and educational responsibilities. Most respondents (89%) felt that their clinic's MD to GC ratio was too high, while clinical load varied. IRD GCs report varying degrees of prior genetic counseling and ophthalmology-specific experience but unanimously desire additional subspecialty-specific training.

CONCLUSIONS

This descriptive assessment of a small subspecialty suggests a need for growth in the number of GCs practicing in IRD clinics and could help to inform development of new GC positions in IRD centers. It also highlights the desire for additional GC-specific education and may be relevant to curriculum development within GC programs.

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.

The Relationship Between Burnout and Occupational Stress in Genetic Counselors

Burnout represents a critical disruption in an individual's relationship with work, resulting in a state of exhaustion in which one's occupational value and capacity to perform are questioned. Burnout can negatively affect an individual's personal life, as well as employers in terms of decreased work quality, patient/client satisfaction, and employee retention. Occupational stress is a known contributor to burnout and occurs as a result of employment requirements and factors intrinsic to the work environment. Empirical research examining genetic counselor-specific burnout is limited; however, existing data suggests that genetic counselors are at increased risk for burnout. To investigate the relationship between occupational stress and burnout in genetic counselors, we administered an online survey to members of three genetic counselor professional organizations. Validated measures included the Maslach Burnout Inventory-General Survey (an instrument measuring burnout on three subscales: exhaustion, cynicism, and professional efficacy) and the Occupational Stress Inventory-Revised (an instrument measuring occupational stress on 14 subscales). Of the 353 respondents, more than 40 % had either considered leaving or left their job role due to burnout. Multiple regression analysis yielded significant predictors for burnout risk. The identified sets of predictors account for approximately 59 % of the variance in exhaustion, 58 % of the variance in cynicism, and 43 % of the variance in professional efficacy. Our data confirm that a significant number of genetic counselors experience burnout and that burnout is correlated with specific aspects of occupational stress. Based on these findings, practice and research recommendations are presented.

Emerging Genetic Counselor Roles within the Biotechnology and Pharmaceutical Industries: as Industry Interest Grows in Rare Genetic Disorders, How are Genetic Counselors Joining the Discussion?

Traditionally, the biotechnology and pharmaceutical industry (BPI) has focused drug development at the mass-market level targeting common medical issues. However, a recent trend is the development of therapies for orphan or rare disorders, including many genetic disorders. Developing treatments for genetic disorders requires an understanding of the needs of the community and translating genomic information to clinical and non-clinical audiences. The core skills of genetic counselors (GCs) include a deep knowledge of genetics and ability to communicate complex information to a broad audience, making GCs a choice fit for this shift in drug development. To date there is limited data defining the roles GCs hold within this industry. This exploratory study aimed to define the roles and motivation of GCs working in BPI, assess job satisfaction, and identify translatable skills and current gaps in GC training programs. The authors surveyed 26 GCs working in BPI in the United States; 79 % work for companies focused on rare disorders. GC positions in BPI are growing, with 57 % of respondents being the first GC in their role. GCs in BPI continue to utilize core genetic counseling competencies, though 72 % felt their training did not fully prepare them for BPI. These data suggest opportunities for exposure to BPI in GC training to better prepare future generations of GCs for these career opportunities. GC satisfaction was high in BPI, notably in areas traditionally reported as less satisfying on the National Society for Genetic Counselors Professional Status Survey: salary and advancement opportunities. BPI's growing interest in rare disorders represents a career opportunity for GCs, addressing both historic areas of dissatisfaction for GCs and BPI's genomic communication needs.

The role of the genetic counsellor: a systematic review of research evidence

In Europe, genetic counsellors are employed in specialist genetic centres or other specialist units. According to the European Board of Medical Genetics, the genetic counsellor must fulfil a range of roles, including provision of information and facilitation of psychosocial adjustment of the client to their genetic status and situation. To evaluate the extent to which genetic counsellors fulfil their prescribed roles, we conducted a systematic review of the published relevant scientific evidence. We searched five relevant electronic databases (Medline, CINAHL, SocIndex, AMED and PsychInfo) using relevant search terms and handsearched four subject-specific journals for research-based papers published in English between 1 January 2000 and 30 June 2013. Of 419 potential papers identified initially, seven satisfied the inclusion criteria for the review. Themes derived from the thematic analysis of the data were: (i) rationale for genetic counsellors to provide care, (ii) appropriate roles and responsibilities and (iii) the types of conditions included in the genetic counsellor caseload. The findings of this systematic review indicate that where genetic counsellors are utilised in specialist genetic settings, they undertake a significant workload associated with direct patient care and this appears to be acceptable to patients. With the burden on genetic services, there is an argument for the increased use of genetic counsellors in countries where they are under-utilised. In addition, roles undertaken by genetic counsellors in specialist genetic settings could be adapted to integrate genetic counsellors into multi-disciplinary teams in other specialisms.

Obstetrician and gynecologists' population-based screening practices

BACKGROUND

The ability to obtain genetic information can now be accomplished in far greater detail, and more quickly than in the past. It is important to understand obstetrician-gynecologists' (ob-gyns) screening practices as these changes occur.

METHODS

Cross-sectional survey was performed by mailing paper surveys to Fellows of the American College of Obstetricians and Gynecologists and a subset of Fellows who belong to the Collaborative Ambulatory Research Network (CARN).

RESULTS

Response rates were 57% for the CARN network. Almost all responders (92%) offer population-based genetic screening in the prenatal period and almost all (93%) conduct counseling prior to the provision of genetic testing. Almost all (92%) counsel patients when the result is positive, with 46% being the primary counselor and 55% calling the patient themselves. When results are negative, 73% counsel with 58% indicating they are the primary counselor and 17% call patients themselves. A total of 72% have received continuing medical education (CME) on genetics within 5 years, with 79% receiving CME at conferences and 21% receiving CME online.

CONCLUSION

Ob-gyns have a large role in providing patients new genetic screening technologies. This role requires a significant knowledge base, some of which can be obtained by online modules; however, our study suggests online education is underutilized as a means for CME on genetic screening among ob-gyns.

Genetic counselors and health literacy: the role of genetic counselors in developing a web-based resource about the Affordable Care Act

The Western States Genetic Services Collaborative (WSGSC) recognized the need for clear and understandable information about the Affordable Care Act (ACA) for families throughout the life course. The genetic counselors working in the WSGSC developed, tested, and implemented a web resource ( http://www.westernstatesgenetics.org/ACA_home.htm ) to help families navigate information about the ACA tailored to their life situation. The training and experience of genetic counselors provide the skills needed to translate complicated information, like that of the ACA, into formats that the general public can comprehend. The website went public in October 2013, and it has been positively received. The development of this website is a good case study in how genetic counseling skills can be applied to public health education and improving health literacy.

A qualitative inquiry of the financial concerns of couples opting to use preimplantation genetic diagnosis to prevent the transmission of known genetic disorders

Preimplantation genetic diagnosis (PGD) is an innovative prenatal testing option because the determination of whether a genetic disorder or chromosomal abnormality is evident occurs prior to pregnancy. However, PGD is not covered financially under the majority of private and public health insurance institutions in the United States, leaving couples to decide whether PGD is financially feasible. The aim of this qualitative study was to understand the role of finances in the decision-making process among couples who were actively considering PGD. In-depth, semi-structured interviews were completed with 18 genetic high-risk couples (36 individual partners). Grounded theory guided the analysis, whereby three themes emerged: 1) Cost is salient, 2) Emotions surrounding affordability, and 3) Financial burden and sacrifice. Ultimately, couples determined that the opportunity to avoid passing on a genetic disorder to a future child was paramount to the cost of PGD, but expressed financial concerns and recognized financial access as a major barrier to PGD utilization.

Looking back and moving forward: an historical perspective from laboratory genetic counselors

Despite a consistent increase in genetic counselors who report working in laboratory positions, there is a relative dearth of literature on laboratory genetic counseling. Semi-structured interviews were completed with nine laboratory genetic counselors to document how positions were created and have changed with time. Interview transcriptions were analyzed for emerging themes. Several common themes were identified, including that early positions were often part-time, laboratory-initiated and had a lack of job definition. Laboratory genetic counselors commented on their evolving roles and responsibilities, with their positions becoming more technical and specialized over time and many taking on managerial and supervisory roles. All genetic counselors surveyed reported using core genetic counseling skills in their positions. The expansion of diagnostic testing and quickly evolving technology were common themes in regards to the future of laboratory genetic counselors, and participants commented on laboratory genetic counselors having expanding roles with data management, result interpretation and reporting, and guidance of other healthcare providers. Other comments included the impact of competition among laboratories and how training programs can better prepare genetic counseling students for a career in the laboratory setting. This study describes the emergence, and subsequent evolution, of laboratory genetic counseling positions as a significant subspecialty of genetic counseling.

Allocation of work activities in a comprehensive cancer genetics program

Hereditary cancer programs that provide risk assessment, genetic education, and counseling services are becoming increasingly common. This article describes one possible approach to providing comprehensive cancer genetics care by a credentialed genetics advanced practice nurse. In addition to the description of the program, data from a recently conducted time study are included to provide insight into work allocation of different program components. Findings from the study indicate that about 41% of the time is spent in direct clinical time with patients and families, including initial visit counseling, phone consultation, and follow-up visits. The rest of the time is spent in other indirect care activities, including previsit activities, risk calculation, clinical trials enrollment, correspondence, teaching, and administrative duties. For those developing or expanding a cancer genetics program, considering all activities that will occur and the time allocated to each activity is important.

Survey of European clinical geneticists on awareness, experiences and attitudes towards direct-to-consumer genetic testing

BACKGROUND

The advent of direct-to-consumer (DTC) genetic testing (GT) has sparked a number of debates regarding the scientific validity of tests, their broad health and ethical implications for society as well as their legal status. To date, relatively few empirical studies have been published regarding this phenomenon. We conducted a survey of European clinical geneticists to gauge their awareness of, experiences with, and attitudes towards DTC GT.

METHODS

We invited 300 clinical geneticists from 28 European countries to complete an online questionnaire. Statistical analyses of closed-ended questions were performed using the STATISTICA software package. Answers to open-ended questions were analysed for recurring themes.

RESULTS

One hundred and thirty-one clinical geneticists answered our survey (response rate, 44%). Eighty-six percent (110/128) of respondents were aware of DTC GT, and over one-third had been contacted by at least one patient regarding these services. The majority (84%) of respondents did not agree with telephone medical supervision outside of an established doctor-patient relationship. The majority of clinical geneticists also found it unacceptable to provide non-face-to-face medical supervision for: (i) a presymptomatic test for a condition with very high penetrance; (ii) a predictive test for a condition that has a 'medium' penetrance of 50% to 60%; and (iii) carrier testing. For conditions that are neither treatable nor preventable and for disorders with serious health consequences, clinical geneticists were almost unanimous in expressing the unacceptability of offering such genetic tests outside of the traditional healthcare setting, without an established physician-patient relationship and without face-to-face medical supervision.

CONCLUSION

A high percentage of European clinical geneticists are aware of DTC GT and the majority do not agree with the model of provision used by many commercial companies for certain severe or actionable health conditions. Despite this disagreement with the DTC model of provision, >85% of respondents said that they would offer genetic counselling to patients who asked for a consultation after having undergone DTC genetic testing. The understanding of the views and opinions of this expert stakeholder group should be considered in the attempts to shape responsible policy and guidelines for these services.

Giving and withholding of information following genomic screening: challenges identified in a study of primary care physicians in Estonia

The use of predictive genomic information to improve medical care remains a contentious topic. However, it is generally agreed that the potential of genomics to improve medicine relies on medical care providers' ability to effectively communicate and put in context the meaning of test results. As the amount of information available increasingly outstrips providers' ability to offer qualified judgments on what the information means, consumers inevitably will be faced with test results of uncertain significance, as well as difficult questions about what they do or do not wish to know. Results of this survey of 64 primary care doctors in Estonia suggests that it may be inherently difficult for physicians to withhold genetic information obtained by genome scans or sequencing, even when they believe that having that information is not in the best interests of their patient. The descriptive data suggest introducing genomic medicine through primary care physicians, as proposed by the Estonian Genome Center of the University of Tartu, will require further genetics education as well as a carefully developed set of guidelines for determining where, when and how to use test results.
