Adolescents with implantable cardioverter defibrillators: a patient and parent perspective.

Background:  An implantable cardioverter defibrillator (ICD) is a device used in the treatment of individuals with life‐threatening cardiac conditions. These include genetic disorders such as long QT syndrome, hypertrophic cardiomyopathy, and Brugada syndrome, all of which have the propensity to cause sudden cardiac death. Adults with ICDs consistently report elevated levels of anxiety and depression, as well as negative lifestyle changes associated with the device. Compared to older ICD recipients, young patients face decades of life with the device and the long‐term impact and implications are important to consider. This research explores the experiences of adolescents living with an ICD. Parents of these adolescents were also included to explore the impact on them as the primary caregivers.

Newborn screening for mucopolysaccharidoses: opinions of patients and their families.

We have conducted a study to assess the opinions of parents of individuals with mucopolysaccharidoses (MPS) and adults with MPS regarding newborn screening (NBS) for this condition, as testing is now technically possible. A questionnaire including a number of hypothetical clinical scenarios about NBS for MPS was distributed to members of MPS support groups from United States and Australia. Questionnaires were returned by 249 members of the US (40% response) and Australian (38% response) support groups. Eleven respondents were adults with MPS and the rest were parents of individuals with MPS. Eighty‐six percent of respondents indicated that they would have wanted NBS for their own children. Ninety‐seven percent supported the use of NBS for MPS in situations where early treatment that favorably impacts on disease outcome is available, 87% supported NBS when a severe form of MPS was diagnosed, but no treatment is available that improves the long‐term outcome and 84% supported NBS for mild MPS where no disease‐modifying treatment is available. The most common reason cited in support of NBS was that NBS could avoid a delay in diagnosis and the accompanying distress that delayed diagnosis created. This study has identified strong support for the introduction of NBS for MPS from this group. Psychosocial benefits of screening may outweigh potential harms.

Educating Genetic Counselors in Australia: Developing an International Perspective

The demand for genetic counseling services is increasing worldwide. This paper highlights the Australian experience of genetic counselor education and the history of the profession. The relevance of local factors, including the healthcare system, the education system and the small population in the evolution of the 1-year training programs are considered as an alternative model for emerging programs. The development of the education and training processes compared to that of other countries namely the United States of America (USA), the United Kingdom (UK) and Canada is discussed. The importance of international collaborations between the programs, to facilitate academic discussion and possible curriculum innovations, and to maintain professional understanding between genetic counselors is emphasized. Core genetic counseling competencies have been published for the UK and USA and an Australian set is proposed. In conclusion future directions are considered, including international issues around genetic counseling certification, reciprocity, and the potential for an Australian role in training genetic counselors in South East Asia.

“Testing Times, Challenging Choices”: An Australian Study of Prenatal Genetic Counseling

In many countries pregnant women deemed to be at increased risk for fetal anomaly following a screening test may attend a genetic counseling session to receive information and support in decision-making about subsequent diagnostic testing. This paper presents findings from an Australian study that explored 21 prenatal genetic counseling sessions conducted by five different genetic counselors. All were attended by pregnant women who had received an increased risk result from a maternal serum screening (MSS) test and who were offered a diagnostic test. Qualitative methods were used to analyze the content and structure of sessions and explore the counseling interactions. Findings from this cohort demonstrate that, within these prenatal genetic counseling sessions, counselor dialogue predominated. Overall the sessions were characterized by: a) an emphasis on information-giving b) a lack of dialogue about relevant sensitive topics such as disability and abortion. Arguably, this resulted in missed opportunities for client deliberation and informed decision-making. These findings have implications for the training and practice of genetic counselors and all healthcare professionals who communicate with women about prenatal testing.

Impact of a Genetic Diagnosis of a Mitochondrial Disorder 5–17 Years After the Death of an Affected Child

This study used in-depth interviews to explore the experiences of parents who were re-contacted with new genetic results many years after the death of a child with a mitochondrial disorder. At the time of their child’s illness, parents had consented to a tissue sample being taken to help with diagnosis of a suspected mitochondrial disorder, and subsequently further DNA testing identified the genetic cause. Parents did not express negative feelings about being re-contacted with new information, and hoped that continuing research might help other families. Positive aspects included relief from feelings of guilt over the cause of the child’s disorder, and having accurate genetic information available for surviving children. Difficult emotional and psychosocial implications included contradictions to previous beliefs about inheritance, deciding how and when to communicate information to surviving children, and coping with new fears for the mother’s health if a gene located in the mitochondrial DNA was identified. In half of the families the new results significantly altered the parents’ understanding of the inheritance pattern. This study highlights the impact of new genetic information offered after a delay of several years, which has the potential to re-open feelings of grief and uncertainty and can present a new inheritance scenario for which research participants or their families are unprepared. Health professionals involved in conveying genetic research results can help to support families through this process.

It wasn't a disaster or anything: Parents' experiences of their child's uncertain chromosomal microarray result.

Chromosomal microarray is an increasingly utilized diagnostic test, particularly in the pediatric setting. However, the clinical significance of copy number variants detected by this technology is not always understood, creating uncertainties in interpreting and communicating results. The aim of this study was to explore parents’ experiences of an uncertain microarray result for their child. This research utilized a qualitative approach with a phenomenological methodology. Semi‐structured interviews were conducted with nine parents of eight children who received an uncertain microarray result for their child, either a 16p11.2 microdeletion or 15q13.3 microdeletion. Interviews were transcribed verbatim and thematic analysis was used to identify themes within the data. Participants were unprepared for the abnormal test result. They had a complex perception of the extent of their childs condition and a mixed understanding of the clinical relevance of the result, but were accepting of the limitations of medical knowledge, and appeared to have adapted to the result. The test result was empowering for parents in terms of access to medical and educational services; however, they articulated significant unmet support needs. Participants expressed hope for the future, in particular that more information would become available over time. This research has demonstrated that parents of children who have an uncertain microarray result appeared to adapt to uncertainty and limited availability of information and valued honesty and empathic ongoing support from health professionals. Genetic health professionals are well positioned to provide such support and aid patients’ and families’ adaptation to their situation as well as promote empowerment.

“It’s Challenging on a Personal Level”—Exploring the ‘Lived Experience’ of Australian and Canadian Prenatal Genetic Counselors

Prenatal genetic counselors work with clients who are at risk of having a child with a fetal anomaly, or who have been diagnosed with a fetal anomaly. This can raise challenging ethical, moral and legal issues for both clients and counselors. Few studies have explored whether this type of work impacts on genetic counselors themselves. Interviews were conducted with 15 prenatal genetic counselors, five from Toronto, Canada and ten from Melbourne, Australia. A qualitative approach was used to allow for an in-depth exploration of the experiences of genetic counselors working in the prenatal setting. While participants reported that working in a prenatal setting affected them in several ways, this paper focuses on one particular unanticipated finding—that of the impact experienced by counselors from both countries while working when pregnant.

Receiving Enzyme Replacement Therapy for a Lysosomal Storage Disorder: A Preliminary Exploration of the Experiences of Young Patients and Their Families

Medical intervention for lysosomal storage disorders becomes part of life, shaping the reality of the condition for affected individuals and families. Enzyme replacement therapy (ERT) is available to treat some lysosomal storage disorders. ERT is costly and time consuming, requiring frequent hospital visits to receive intravenous infusions. This qualitative study sought to explore the impact of receiving ERT for a lysosomal storage disorder on the health related quality of life (HRQoL) of young patients and their families. Fifteen semi–structured interviews were conducted with young people and parents and siblings of young people accessing ERT for Pompe disease, Gaucher disease or mucopolysaccharidosis types I or II living in Victoria, Australia. Interviews were transcribed then analyzed thematically. The biopsychosocial model assisted in interpreting themes. Findings revealed positive attitudes towards ERT, with noticed improvements in physical and psychosocial well-being. Participants prioritised intervention over other activities and provided suggestions for improving current service delivery. Communication with family members and professionals was deemed important, especially in respect to information provision. Participants described challenges associated with living with a lysosomal storage disorder and receiving ERT and coping strategies, such as positive thinking and ways to manage uncertainty. These findings provide valuable insights into the impact of living with a chronic genetic condition and receiving intensive treatment on HRQoL.

“There’s a Whole Different Way of Working with Adolescents”: Interviews with Australian Genetic Counselors About their Experiences with Adolescent Clients

Adolescence is a developmental period marked by unique physical, psychological and social changes. Guidelines about working with adolescents are available to health professionals in other fields, yet few resources are tailored specifically to genetic counselors. The current qualitative study explored the experiences of genetic counselors who work with adolescent clients to determine whether challenges exist and if further training and support are needed. Semi-structured interviews were conducted with 11 genetic counselors from Australia. Interview transcripts were analyzed using thematic analysis from which 7 key themes emerged: 1) Adolescents: A distinct client group? 2) Characteristics of adolescents; 3) Strategies for working with adolescents; 4) Confidentiality; 5) Parental involvement and presence in sessions; 6) Benefits of working with adolescents; and 7) The effectiveness of past training and education. The findings hold important implications for clinical practice and may inform future training programs and guidelines for genetic counselors internationally.

Genetic Counseling for Indigenous Australians: an Exploratory Study from the Perspective of Genetic Health Professionals.

Indigenous populations are thought to have particularly low levels of access to genetic health services, and cultural issues may be a contributing factor. This article presents the findings of the first study of genetic health service provision to Indigenous Australians. This qualitative study aimed to identify elements of culturally-competent genetic health service provision in Indigenous Australian contexts. Twelve semi-structured interviews were conducted with genetic counselors and clinical geneticists from around Australia who had delivered services to Indigenous Australians. Participants were asked to describe their experiences and identify any collective cultural needs of Indigenous clients, as well as comment on specific training and resources they had received or used. Interviews were audio-recorded and transcribed with thematic analysis conducted on the data. The findings show that participants were reluctant to generalize the needs of Indigenous peoples. Some participants asserted that Indigenous peoples have needs that differ from the general population, while others felt that there were no collective cultural needs, instead advocating an individualized approach. Being flexible and practical, taking time to build rapport, recognizing different family structures and decision-making processes, as well as socio-economic disadvantage were all identified as important factors in participants’ interactions with Indigenous clients. Indigenous support workers and hospital liaison officers were seen as valuable resources for effective service provision. The implications of this study for training and practice are discussed.
