Strength of the genetic counselor: patient relationship is associated with extent of increased empowerment in patients with arrhythmogenic cardiomyopathy

Applying theories, models, and frameworks to help genetic counselors and students achieve clinical and professional goals

Some genetic counselors (GCs) may find theories, models, and frameworks (TMFs) useful in clinical skills selection and when reflecting on or evaluating genetic counseling practice. This paper aims to demonstrate how TMFs can be used to postulate how different skills may impact patients'/clients' decisions, behaviors, and outcomes and consider how multiple TMFs can inform the use of various skills or strategies to achieve different goals. Additionally, we provide examples of TMFs that may help GCs in nonclinical aspects of their work, such as implementing and evaluating new interventions or service delivery models. To guide the selection of appropriate TMFs, we provide a set of questions to consider and include examples of skills and approaches that align with different TMFs. While TMFs provide a structured approach and valuable guidance that may help advance genetic counseling practice, they have certain limitations. Additional research is necessary to determine the effectiveness of using TMFs to guide clinical practice and improve patient/client outcomes.

Promise and Peril of a Genotype-First Approach to Mendelian Cardiovascular Disease

Precision medicine, which among other aspects includes an individual's genomic data in diagnosis and management, has become the standard-of-care for Mendelian cardiovascular disease (CVD). However, early identification and management of asymptomatic patients with potentially lethal and manageable Mendelian CVD through screening, which is the promise of precision health, remains an unsolved challenge. The reduced costs of genomic sequencing have enabled the creation of biobanks containing in-depth genetic and health information, which have facilitated the understanding of genetic variation, penetrance, and expressivity, moving us closer to the genotype-first screening of asymptomatic individuals for Mendelian CVD. This approach could transform health care by diagnostic refinement and facilitating prevention or therapeutic interventions. Yet, potential benefits must be weighed against the potential risks, which include evolving variant pathogenicity assertion or identification of variants with low disease penetrance; costly, stressful, and inappropriate diagnostic evaluations; negative psychological impact; disqualification for employment or of competitive sports; and denial of insurance. Furthermore, the natural history of Mendelian CVD is often unpredictable, making identification of those who will benefit from preventive measures a priority. Currently, there is insufficient evidence that population-based genetic screening for Mendelian CVD can reduce adverse outcomes at a reasonable cost to an extent that outweighs the harms of true-positive and false-positive results. Besides technical, clinical, and financial burdens, ethical and legal aspects pose unprecedented challenges. This review highlights key developments in the field of genotype-first approaches to Mendelian CVD and summarizes challenges with potential solutions that can pave the way for implementing this approach for clinical care.

2024 HRS expert consensus statement on arrhythmias in the athlete: Evaluation, treatment, and return to play

Youth and adult participation in sports continues to increase, and athletes may be diagnosed with potentially arrhythmogenic cardiac conditions. This international multidisciplinary document is intended to guide electrophysiologists, sports cardiologists, and associated health care team members in the diagnosis, treatment, and management of arrhythmic conditions in the athlete with the goal of facilitating return to sport and avoiding the harm caused by restriction. Expert, disease-specific risk assessment in the context of athlete symptoms and diagnoses is emphasized throughout the document. After appropriate risk assessment, management of arrhythmias geared toward return to play when possible is addressed. Other topics include shared decision-making and emergency action planning. The goal of this document is to provide evidence-based recommendations impacting all areas in the care of athletes with arrhythmic conditions. Areas in need of further study are also discussed.

Measuring the therapeutic bond in genetic counseling: Testing measurement error in the bond subscale of the Working Alliance Inventory

The therapeutic relationship is a key component of successful genetic counseling. In psychotherapy, a strong therapeutic relationship can improve patient health outcomes and a poor relationship can worsen psychological functioning. Investigation of the therapeutic relationship in genetic counseling has shown evidence for a similar pattern. Reliable measurement of the therapeutic relationship is necessary for consistency across studies in the genetic counseling context. One measure that has been adapted for use in genetic counseling is the Working Alliance Inventory (WAI). However, there have been no studies of the factor structure or item-level method bias analyses for the genetic counseling-adapted version of the WAI. The goal of this study was to test the factor structure of the WAI observer version (WAI-O) bond subscale and assess method bias in a genetic counseling context. We hypothesized that differences in factor structures would exist for items that were positively (n = 9) versus negatively (n = 3) worded (reverse coded). Secondary data analysis was performed on two data sets that utilized the WAI-O in genetic counseling contexts. Data set 1 used simulated genetic counseling sessions that were judged by analog clients recruited through crowdsourcing platforms (N = 861). Data set 2 was conducted with genetic counseling clients, and sessions were evaluated by a research team (N = 120). Principal axis factor analysis with oblique oblimin rotation supported a two-factor solution for the WAI-O bond subscale across data sets. Items factored based on wording, with the positively worded items loading together and the negatively worded items loading on the second factor. Confirmatory factor analyses supported the removal of all negatively worded items from the instrument across data sets. Results suggest that the negatively worded items on the WAI-O may be capturing a construct inconsistent with the positively worded items and support rewording and/or excluding them from use for a more reliable measure of the therapeutic bond.

Principles of Genetic Counseling in Inherited Heart Conditions

Cardiac genetic counseling is the process of helping individuals adapt to a personal diagnosis or family history of an inherited heart condition. The process is shown to benefit patients and includes specialized skills, such as counseling children and interpreting complex genetic results. Emerging areas include: evolving service delivery models for caring for patients and communicating risk to relatives, new areas of need including postmortem molecular autopsy, and new populations of individuals found to carry a likely pathogenic/pathogenic cardiac variant identified through genomic screening. This article provides an overview of the cardiac genetic counseling process and evolving areas in the field.

Evolving cardiovascular genetic counseling needs in the era of precision medicine

In the era of Precision Medicine the approach to disease diagnosis, treatment, and prevention is being transformed across medical specialties, including Cardiology, and increasingly involves genomics approaches. The American Heart Association endorses genetic counseling as an essential component in the successful delivery of cardiovascular genetics care. However, with the dramatic increase in the number of available cardiogenetic tests, the demand, and the test result complexity, there is a need not only for a greater number of genetic counselors but more importantly, for highly specialized cardiovascular genetic counselors. Consequently, there is a pressing need for advanced cardiovascular genetic counseling training, along with innovative online services, telemedicine, and patient-facing digital tools, as the most effective way forward. The speed of implementation of these reforms will be of essence in the translation of scientific advancements into measurable benefits for patients with heritable cardiovascular disease and their families.

Perceived self-efficacy and empowerment in patients at increased risk of sudden cardiac arrest

Background

The role of multidisciplinary clinics for psychosocial care is increasingly recognized for those living with inherited cardiac conditions (ICC). In Canada, access to healthcare providers differ between clinics. Little is known about the relationship between access to specialty care and a patient's ability to cope with, and manage their condition.

Methods

We leveraged the Hearts in Rhythm Organization (HiRO) to conduct a cross-sectional, community-based survey of individuals with ICC and their family members. We aimed to describe access to services, and explore the relationships between participants' characteristics, cardiac history and self-reported health status and self-efficacy (GSE: General Self-Efficacy Scale) and empowerment (GCOS-24: Genetic Counseling Outcome Scale).

Results

We collected 235 responses from Canadian participants in 10 provinces and territories. Overall, 63% of participants reported involvement of a genetic counsellor in their care. Access to genetic testing was associated with greater empowerment [mean GCOS-24: 121.14 (SD = 20.53) vs. 105.68 (SD = 21.69); p = 0.004]. Uncertain genetic test results were associated with lower perceived self-efficacy (mean GSE: uncertain = 28.85 vs. positive = 33.16, negative = 34.13; p = 0.01). Low global mental health scores correlated with both lower perceived self-efficacy and empowerment scores, with only 11% of affected participants reporting involvement of psychology services in their care.

Conclusion

Differences in resource accessibility, clinical history and self-reported health status impact the perceived self-efficacy and empowerment of patients with ICC. Future research evaluating interventions to improve patient outcomes is recommended.
