Ma A, O'Shea R, Wedd L, Wong C, Jamieson RV, Rankin N. What is the power of a genomic multidisciplinary team approach? A systematic review of implementation and sustainability. Eur J Hum Genet 2024; 32:381-391. [PMID: 38378794 PMCID: PMC10999446 DOI: 10.1038/s41431-024-01555-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 12/07/2023] [Accepted: 01/26/2024] [Indexed: 02/22/2024] Open
Abstract
Due to the increasing complexity of genomic data interpretation, and need for close collaboration with clinical, laboratory, and research expertise, genomics often requires a multidisciplinary team (MDT) approach. This systematic review aims to establish the evidence for effectiveness of the genomic multidisciplinary team, and the implementation components of this model that can inform precision care. MEDLINE, Embase and PsycINFO databases were searched in 2022 and 2023. We included qualitative and quantitative studies of the genomic MDT, including observational and cohort studies, for diagnosis and management, and implementation outcomes of effectiveness, adoption, efficiency, safety, and acceptability. A narrative synthesis was mapped against the Genomic Medicine Integrative Research framework. 1530 studies were screened, and 17 papers met selection criteria. All studies pointed towards the effectiveness of the genomic MDT approach, with 10-78% diagnostic yield depending on clinical context, and an increased yield of 6-25% attributed to the MDT. The genomic MDT was found to be highly efficient in interpretation of variants of uncertain significance, timeliness for a rapid result, made a significant impact on management, and was acceptable for adoption by a wide variety of subspecialists. Only one study utilized an implementation science based approach. The genomic MDT approach appears to be highly effective and efficient, facilitating higher diagnostic rates and improved patient management. However, key gaps remain in health systems readiness for this collaborative model, and there is a lack of implementation science based research especially addressing the cost, sustainability, scale up, and equity of access.

Abstract
Genetic testing is increasingly used in clinical practice in the neonatal period, including in NICUs. This testing may have psychological consequences for parents. To best support families, neonatal clinicians should be aware of the various ways in which parents view and respond to genetic testing. In this review, we summarize research on the parental experience of having a newborn infant undergo genetic testing.

Clinical utility of early rapid genome sequencing in the evaluation of patients with differences of sex development. Am J Med Genet A 2024; 194:351-357. [PMID: 37789729 DOI: 10.1002/ajmg.a.63377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 08/08/2023] [Accepted: 08/09/2023] [Indexed: 10/05/2023]
Abstract
Establishing an early and accurate genetic diagnosis among patients with differences of sex development (DSD) is crucial in guiding the complex medical and psychosocial care they require. Genetic testing routinely utilized in clinical practice for this population is predicated upon physical exam findings and biochemical and endocrine profiling. This approach, however, is inefficient and unstandardized. Many patients with DSD, particularly those with 46,XY DSD, never receive a molecular genetic diagnosis. Rapid genome sequencing (rGS) is gaining momentum as a first-tier diagnostic instrument in the evaluation of patients with DSD given its ability to provide greater diagnostic yield and timely results. We present the case of a patient with nonbinary genitalia and systemic findings for whom rGS identified a novel variant of the WT1 gene and resulted in a molecular diagnosis within two weeks of life. This timeframe of diagnosis for syndromic DSD is largely unprecedented at our institution. Rapid GS expedited mobilization of a multidisciplinary medical team; enabled early understanding of clinical trajectory; informed planning of medical and surgical interventions; and guided individualized psychosocial support provided to the family. This case highlights the potential of early rGS in transforming the evaluation and care of patients with DSD.

[PMID: 37795501 PMCID: PMC10547469 DOI: 10.1212/cpj.0000000000200192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 07/07/2023] [Indexed: 10/06/2023]
Abstract
Background and Objectives Global developmental delay/intellectual disability (GDD/ID) are among the most common neurologic conditions evaluated by child neurologists in the United States. No recent neurology-specific guidelines for GDD/ID diagnostic evaluation exist, which could lead to practice variability. We assessed current practices in GDD/ID diagnostic evaluation among US child neurologists, including drivers of exome sequencing (ES). Methods A 19-item online anonymous survey was distributed between April 2021 and September 2021 to 953 eligible child neurologists by email and/or online platforms through the American Academy of Neurology and Child Neurology Society. Multinomial logistic regression was used to determine the predictors of sending ES as a part of GDD/ID diagnostic evaluation. Results Of 172 unique respondents, 69.2% reported almost always obtaining a chromosomal microarray while 10.5% reported almost always pursuing ES. However, 65.1% identified ES as a first-tier diagnostic test for GDD/ID. Clinical practice demographics independently associated with a higher likelihood of pursuit of ES were more years of experience (p = 0.002) and more people with GDD/ID in one's practice (p < 0.001). Inclusion of brain MRI, EEG, and metabolic laboratory values as part of GDD/ID diagnostic evaluation varied widely. Modalities to screen for treatable disorders (ES or metabolic laboratory values) were reported to be consistently used by only 24.8% of respondents. Respondents identified key barriers to the pursuit of ES including the need for genetics referral/genetic counseling and insurance coverage/out-of-pocket cost. Discussion Among US child neurologists, there is marked practice variability in GDD/ID diagnostic evaluation across multiple types of testing, raising concern for disparities in care. There is a widespread lack of screening for treatable causes of ID, which may lead to missed diagnoses and avoidable morbidity. Despite most respondents' support for ES as a first-tier diagnostic test for GDD/ID, only a small minority routinely pursue ES as a part of their evaluation. Provider-level factors (years of experience, percent of patients with GDD/ID) and system-level barriers (access to genetics expertise, lack of insurance coverage) were determinants of the frequency of use of ES. These findings suggest the need for updated consensus guidelines and advocacy/education to improve child neurologists' ability to pursue ES for GDD/ID.

Abstract
In the last few decades, medical genetics has undergone a revolution because of the development of technologies and informatics approaches that can generate and analyze large amounts of genomic data. Pediatricians have been hugely affected by these changes. The early age of presentation for birth defects and neurocognitive disorders, together with a shortage of trained genetics professionals, has increased consultations for conditions with a genetic cause, not only in pediatric practice but also in other subspecialties. In the future, genetic testing in childhood is likely to include pediatricians, who can initiate testing in partnership with trained genetics professionals.

Abstract
Molecular diagnosis of paediatric inborn errors of immunity (IEI) influences management decisions and alters clinical outcomes, through early use of targeted and curative therapies. The increasing demand for genetic services has resulted in growing waitlists and delayed access to vital genomic testing. To address this issue, the Queensland Paediatric Immunology and Allergy Service, Australia, developed and evaluated a mainstreaming model of care to support point-of-care genomic testing for paediatric IEI. Key features of the model of care included a genetic counsellor embedded in the department, state-wide multidisciplinary team meetings, and variant prioritisation meetings to review whole exome sequencing (WES) data. Of the 62 children presented at the MDT, 43 proceeded to WES, of which nine (21%) received a confirmed molecular diagnosis. Changes to treatment and management were reported for all children with a positive result, including curative hematopoietic stem cell transplantation (n = 4). Four children were also referred for further investigations of variants of uncertain significance or additional testing due to ongoing suspicion of genetic cause after negative result. Demonstrating engagement with the model of care, 45% of the patients were from regional areas and on average, 14 healthcare providers attended the state-wide multidisciplinary team meetings. Parents demonstrated understanding of the implications of testing, reported minimal decisional regret post-test, and identified benefits to genomic testing. Overall, our program demonstrated the feasibility of a mainstreaming model of care for paediatric IEI, improved access to genomic testing, facilitated treatment decision-making, and was acceptable to parents and clinicians alike.

Abstract
BACKGROUND Emerging studies suggest that whole genome sequencing provides additional diagnostic yield of genomic variants when compared with chromosomal microarray analysis in the etiologic diagnosis of infants and children with suspected genetic diseases. However, the application and evaluation of whole genome sequencing in prenatal diagnosis remain limited. OBJECTIVE This study aimed to evaluate the accuracy, efficacy, and incremental yield of whole genome sequencing in comparison with chromosomal microarray analysis for routine prenatal diagnosis. STUDY DESIGN In this prospective study, a total of 185 unselected singleton fetuses with ultrasound-detected structural anomalies were enrolled. In parallel, each sample was subjected to whole genome sequencing and chromosomal microarray analysis. Aneuploidies and copy number variations were detected and analyzed in a blinded fashion. Single nucleotide variations and insertions and deletions were confirmed by Sanger sequencing, and trinucleotide repeats expansion variants were verified using polymerase chain reaction plus fragment-length analysis. RESULTS Overall, genetic diagnoses using whole genome sequencing were obtained for 28 (15.1%) cases. Whole genome sequencing not only detected all these aneuploidies and copy number variations in the 20 (10.8%) diagnosed cases identified by chromosomal microarray analysis, but also detected 1 case with an exonic deletion of COL4A2 and 7 (3.8%) cases with single nucleotide variations or insertions and deletions. In addition, 3 incidental findings were detected including an expansion of the trinucleotide repeat in ATXN3, a splice-sites variant in ATRX, and an ANXA11 missense mutation in a case of trisomy 21. CONCLUSION Compared with chromosomal microarray analysis, whole genome sequencing increased the additional detection rate by 5.9% (11/185). Using whole genome sequencing, we detected not only aneuploidies and copy number variations, but also single nucleotide variations and insertions and deletions, trinucleotide repeat expansions, and exonic copy number variations with high accuracy in an acceptable turnaround time (3-4 weeks). Our results suggest that whole genome sequencing has the potential to be a new promising prenatal diagnostic test for fetal structural anomalies.

Abstract
INTRODUCTION As routine genomic testing expands, so too does the opportunity to look for additional health information unrelated to the original reason for testing, termed additional findings (AF). Analysis for many different types of AF may be available, particularly to families undergoing trio genomic testing. The optimal model for service delivery remains to be determined, especially when the original test occurs in the acute care setting. METHODS AND ANALYSIS Families enrolled in a national study providing ultrarapid genomic testing to critically ill children will be offered analysis for three types of AF on their stored genomic data: paediatric-onset conditions in the child, adult-onset conditions in each parent and reproductive carrier screening for the parents as a couple. The offer will be made 3-6 months after diagnostic testing. Parents will have access to a modified version of the Genetics Adviser web-based decision support tool before attending a genetic counselling appointment to discuss consent for AF. Parental experiences will be evaluated using qualitative and quantitative methods on data collected through surveys, appointment recordings and interviews at multiple time points. Evaluation will focus on parental preferences, uptake, decision support use and understanding of AF. Genetic health professionals' perspectives on acceptability and feasibility of AF will also be captured through surveys and interviews. ETHICS AND DISSEMINATION This project received ethics approval from the Melbourne Health Human Research Ethics Committee as part of the Australian Genomics Health Alliance protocol: HREC/16/MH/251. Findings will be disseminated through peer-review journal articles and at conferences nationally and internationally.

Abstract
Rapid genomic testing (rGT) enables genomic information to be available in a matter of hours, allowing it to be used in time-critical settings, such as intensive care units. Although rGT has been shown to improve diagnostic rates in a cost-effective manner, it raises ethical questions around a range of different areas, including obtaining consent and clinical decision-making. While some research has examined the perspectives of parents and genetics health professionals, the attitudes of intensive care clinicians remain under-explored. To address this gap, we administered an online survey to English-speaking neonatal/paediatric intensivists in Europe, Australasia and North America. We posed two ethical scenarios: one relating to obtaining consent from the parents and the second assessing decision-making regarding the provision of life-sustaining treatments. Descriptive statistics were used to analyse the data. We received 40 responses from 12 countries. About 50-75% of intensivists felt that explicit parental consent was necessary for rGT. About 68-95% felt that a diagnosis from rGT should affect the provision of life-sustaining care. Results were mediated by intensivists' level of experience. Our findings show divergent attitudes toward ethical issues generated by rGT among intensivists and suggest the need for guidance regarding ethical decision-making for rGT.

Abstract
Ultra-rapid genomic sequencing (urGS) is increasingly used in neonatal and pediatric intensive care settings (NICU/PICU), demonstrating high diagnostic and clinical utility. This study aimed to explore the perspectives of healthcare professionals (HPs) and the challenges raised by urGS, particularly when making treatment decisions. Four focus groups and two interviews were conducted with HPs who had experience using urGS in NICU/PICU. Inductive content analysis was used to analyze the data. Nineteen HPs participated overall (eight clinical geneticists, nine genetic counselors, and two intensivists). One challenging area of practice identified by HPs was setting realistic expectations for outcomes of urGS among HPs and families. HPs reported modifying pre-test counseling to include life-limiting diagnoses as a possible test outcome and felt concerned about the timing of the test and its impact on parent-child bonding. UrGS results of uncertain prognostic significance posed considerable challenges. Moral distress arose when families and HPs were misaligned regarding treatment goals following the urGS diagnosis. We identified areas of practice that remain ethically challenging for HPs using urGS in the NICU/PICU. HPs experiences of using urGS in the NICU/PICU could inform specialized training in withdrawal of treatment decision making for the genomics workforce.

Abstract
Rare genetic disorders affect as many as 3%-5% of all babies born. Approximately 10,000 such disorders have been identified or hypothesized to exist. Treatment is supportive except in a limited number of instances where specific therapies exist. Development of new therapies has been hampered by at least two major factors: difficulty in diagnosing diseases early enough to enable treatment before irreversible damage occurs, and the high cost of developing new drugs and getting them approved by regulatory agencies. Whole-genome sequencing (WGS) techniques have become exponentially less expensive and more rapid since the beginning of the human genome project, such that return of clinical data can now be achieved in days rather than years and at a cost that is comparable to other less expansive genetic testing. Thus, it is likely that WGS will ultimately become a mainstream, first-tier NBS technique at least for those disorders without appropriate high-throughput functional tests. However, there are likely to be several steps in the evolution to this end. The clinical implications of these advances are profound but highlight the bottlenecks in drug development that still limit transition to treatments. This article summarizes discussions arising from a recent National Institute of Health conference on nucleic acid therapy, with a focus on the impact of WGS in the identification of diagnosis and treatment of rare genetic disorders.

Abstract
The clinical utility of rapid genome sequencing (rGS) in critically unwell infants has been consistently demonstrated, and there are calls for rGS to be implemented as a first-line test in the NICU. A diagnosis from rGS can enable rapid initiation of precision treatment, making it potentially lifesaving. However, in many patients rGS leads to the diagnosis of severe and life-limiting conditions, prompting discussion with families about withdrawal of life-sustaining treatment. The complexity of information about rGS, together with the heightened emotions of parents in the NICU, poses significant challenges for informed decision making in this context. We present a case where both parents are unable to provide informed consent, and the treating team must decide whether to proceed with rGS. Our discussion highlights the important differences between genome sequencing and other types of genetic testing, and the crucial role played by pre-test counseling in facilitating informed consent and preparing parents for a range of possible outcomes. We then discuss the consent paradigms at play in NICUs; whereas admission generally comes with an understanding that the treating team will perform interventions thought to be in the best interest of the child, rGS is substantially different because of its long-term implications for patients and family members. Finally, we look at the ethical interplay between parental consent and the interests of the child. We conclude by showing how cases like this are resolved at our tertiary center and how they may be resolved differently in future.

Abstract
The delivery of rapid genomic sequencing (rGS) to critically unwell children in intensive care occurs at a time of immense pressure and stress for parents. Contact with families after result disclosure, particularly after hospital discharge, presents an opportunity to meet their psychological, medical and information needs as they evolve. This study explores the preferences and perspectives of health professionals and parents of genetics follow up after rGS. Semi-structured interviews were conducted with 30 parents, seven genetic counsellors (GCs) and four intensive care physicians with experience in rGS. Transcripts were analysed using reflexive thematic analysis. Current practices surrounding genetics follow up after rGS were highly variable, resulting in some families not receiving the ongoing care they needed. Reasons identified by families for wanting follow-up care represented only a subset of those identified by health professionals. While GCs routinely provided their details to allow parents to initiate further contact, this was not always sufficient for follow-up care. Health professionals identified both organisational and psychosocial barriers to conducting follow up. As rGS transforms the diagnostic pathway in rare disease, there is a need for a co-designed, standardised but flexible model for follow-up care with genetics professionals so that families' evolving needs are met.

Abstract
BACKGROUND Rapid genome-wide sequencing (rGWS) is being increasingly used to aid in prognostication and decision-making for critically ill newborns and children. Although its feasibility in this fast-paced setting has been described, this new paradigm of inpatient genetic care raises new ethical challenges. OBJECTIVE A scoping review was performed to (1) identify salient ethical issues in this area of practice; and (2) bring attention to gaps and ethical tensions that warrant more deliberate exploration. METHODS Data sources, Ovid Medline and Cochrane Central Register of Controlled Trials, were searched up to November 2021. Articles included were those in English relating to rGWS deployed rapidly in a critical care setting. Publications were examined for ethical themes and were further characterized as including a superficial or in-depth discussion of that theme. New themes were inductively identified as they emerged. RESULTS Ninety-nine studies, published in 2012 or thereafter, met inclusion criteria. Themes identified elaborated upon established ethical principles related to beneficence and nonmaleficence (ie, clinical utility, medical uncertainty, impact on family, and data security) autonomy (ie, informed consent), and justice (ie, resource allocation and disability rights). Many themes were only narrowly discussed. CONCLUSIONS The application of rGWS in neonatal and pediatric acute care is inherently tied to ethically charged issues, some of which are reported here. Attention to the ethical costs and benefits of rGWS is not always discussed, with important gaps and unanswered questions that call for ongoing focus on these ethical considerations in this next application of acute care genomics.

Abstract
Advances in prenatal diagnosis have made medical, psychological, and ethical issues regarding the diagnosis of fetal anomalies a crucial topic of research. This study identified the needs of parents of unborn babies with fetal anomalies and their views regarding the services of interdisciplinary team members in charge of assisting them. The sample consisted of 30 parents and 40 team members from a women's health education and research hospital. Data were collected through face-to-face interviews and were qualitatively analyzed using the phenomenological method of interpretation. The results showed that parents' physical, psychological, social, and spiritual needs during pregnancy, childbirth, and postpartum were not fully met after their unborn babies were diagnosed with fetal anomalies. The results also showed that team members needed a structured program, legal regulations, and training to provide holistic care.

Abstract
Rapid genomic sequencing (rGS) is being increasingly used in neonatal and paediatric intensive care units. While there is emerging evidence of clinical utility and cost-effectiveness, concerns have been raised regarding the impact of delivering genomic results in an acute care setting. To help investigate these concerns, we analysed survey data collected from caregivers whose children had received rGS through a national rapid genomic diagnosis program. The impact of rGS on families was assessed through the PedsQL2.0 Family Impact Module and the State-Trait Anxiety Inventory (STAI-6). Sixty-one parents/carers completed the survey during the study period (response rate 48%; 61/128). Mean parent and family functioning was reduced in this sample, reflecting the stressful conditions facing families with critically unwell children. We found caregivers whose children had received a diagnostic result through rGS reported a reduced family relationships score compared to caregivers of children who did not receive a diagnosis. These findings have implications for genetic counselling practice in this setting.

Abstract
Background: The UK 100,000 Genomes Project was a transformational research project which facilitated whole genome sequencing (WGS) diagnostics for rare diseases. We evaluated experiences of introducing WGS in Northern Ireland, providing recommendations for future projects. Methods: This formative evaluation included (1) an appraisal of the logistics of implementing and delivering WGS, (2) a survey of participant self-reported views and experiences, (3) semi-structured interviews with healthcare staff as key informants who were involved in the delivery of WGS and (4) a workshop discussion about interprofessional collaboration with respect to molecular diagnostics. Results: We engaged with >400 participants, with detailed reflections obtained from 74 participants including patients, caregivers, key National Health Service (NHS) informants, and researchers (patient survey n = 42; semi-structured interviews n = 19; attendees of the discussion workshop n = 13). Overarching themes included the need to improve rare disease awareness, education, and support services, as well as interprofessional collaboration being central to an effective, mainstreamed molecular diagnostic service. Conclusions: Recommendations for streamlining precision medicine for patients with rare diseases include administrative improvements (e.g., streamlining of the consent process), educational improvements (e.g., rare disease training provided from undergraduate to postgraduate education alongside genomics training for non-genetic specialists) and analytical improvements (e.g., multidisciplinary collaboration and improved computational infrastructure).

Abstract
Importance Infants with hypotonia can present with a variety of potentially severe clinical signs and symptoms and often require invasive testing and multiple procedures. The wide range of clinical presentations and potential etiologies leaves diagnosis and prognosis uncertain, underscoring the need for rapid elucidation of the underlying genetic cause of disease. Observations The clinical application of exome sequencing or genome sequencing has dramatically improved the timely yield of diagnostic testing for neonatal hypotonia, with diagnostic rates of greater than 50% in academic neonatal intensive care units (NICUs) across Australia, Canada, the UK, and the US, which compose the International Precision Child Health Partnership (IPCHiP). A total of 74% (17 of 23) of patients had a change in clinical care in response to genetic diagnosis, including 2 patients who received targeted therapy. This narrative review discusses the common causes of neonatal hypotonia, the relative benefits and limitations of available testing modalities used in NICUs, and hypotonia management recommendations. Conclusions and Relevance This narrative review summarizes the causes of neonatal hypotonia and the benefits of prompt genetic diagnosis, including improved prognostication and identification of targeted treatments which can improve the short-term and long-term outcomes. Institutional resources can vary among different NICUs; as a result, consideration should be given to rule out a small number of relatively unique conditions for which rapid targeted genetic testing is available. Nevertheless, the consensus recommendation is to use rapid genome or exome sequencing as a first-line testing option for NICU patients with unexplained hypotonia. As part of the IPCHiP, this diagnostic experience will be collected in a central database with the goal of advancing knowledge of neonatal hypotonia and improving evidence-based practice.

Abstract
Rapid genomic testing in critically ill neonatal and paediatric patients has transformed the paradigm of rare disease diagnosis, delivering results in real time to inform patient management. More than 20 studies totalling over 1500 patients from diverse healthcare settings worldwide have now been published, forming a compelling evidence base for healthcare system implementation. We review the reported diagnostic and clinical outcomes, as well as broader evaluations of family and professional experiences, cost effectiveness, implementation challenges and bioethical issues arising from rapid testing. As rapid genomic testing transitions from the research to the healthcare setting to become a 'standard of care' test, there is a need to develop effective service delivery models to support scalability at both the laboratory and clinical level and promote equity of access, prompt test initiation, integrated multidisciplinary input and holistic family support. Harnessing the high level of professional engagement with rapid genomic testing programmes will continue to drive innovation and adoption, while close integration with emerging precision medicine approaches will be necessary to deliver on the promise of reduced infant and child mortality.

Abstract
Genomic testing is becoming routine for diagnosing rare childhood genetic disease. Evidence underlying sustainable implementation is limited, focusing on short-term endpoints such as diagnostic yield, unable to fully characterize patient and family valued outcomes. Although genomic testing is becoming widely available, evidentiary and outcomes uncertainty persist as key challenges for implementation. We examine whether the current evidence base reflects public tolerance for uncertainty for genomics to diagnose rare childhood genetic disease. We conducted focus groups with general population parents in Vancouver, Canada, and Oxford, United Kingdom, to discuss expectations and concerns related to genomic testing to diagnose rare childhood genetic disease. Applying a purposive sampling technique, recruitment continued until thematic saturation was reached. Transcripts were analysed using thematic analysis. Thirty-three parents participated across four focus groups. Participants valued causal diagnoses alongside management strategies to improve patient health and wellbeing. Further, participants valued expanding the evidence base to reduce evidentiary uncertainty while ensuring security of information. Willingness to pay out of pocket for testing reflected perceived familial health benefit. Diagnostic yield fails to fully capture valued outcomes, and efforts to resolve uncertainty better reflect public priorities. Evaluations of genomic testing that fully integrate valued endpoints are necessary to ensure consistency with best practices and public willingness to accept the uncertain familial benefit.

Parents' experiences of decision making for rapid genomic sequencing in intensive care. Eur J Hum Genet 2021; 29:1804-1810. [PMID: 34426661 DOI: 10.1038/s41431-021-00950-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 06/20/2021] [Accepted: 08/12/2021] [Indexed: 01/14/2023] Open
Abstract
The clinical utility of rapid genomic sequencing (rGS) for critically unwell infants and children has been well demonstrated. Parental capacity for informed consent has been questioned, yet limited empirical data exists to guide clinical service delivery. In an Australian nationwide clinical implementation project offering rGS for critically unwell infants and children, parents made a decision about testing in under a day on average. This study reports parents' experiences of decision making for rGS within this rapid timeframe to inform pre-test counselling procedures for future practice. A nationwide sample of 30 parents, whose children were amongst the first to receive rGS, were interviewed. We found that framing and delivery of rGS require careful consideration to support autonomous decision making and avoid implicit coercion in a stressful intensive care setting. Many parents described feeling 'special' and 'lucky' that they were receiving access to expensive and typically time-consuming genomic sequencing. Thematic analysis revealed a spectrum of complexity for decision making about rGS. Some parents consented quickly and were resistant to pre-test counselling. Others had a range of concerns and described deliberating about their decision, which they felt rushed to make. This research identifies tensions between the medical imperative of rGS and parents' decision making, which need to be addressed as rGS becomes routine clinical care.

Exome and genome sequencing for pediatric patients with congenital anomalies or intellectual disability: an evidence-based clinical guideline of the American College of Medical Genetics and Genomics (ACMG). Genet Med 2021; 23:2029-2037. [PMID: 34211152 DOI: 10.1038/s41436-021-01242-6] [Citation(s) in RCA: 214] [Impact Index Per Article: 71.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 05/26/2021] [Accepted: 05/26/2021] [Indexed: 01/22/2023] Open
Abstract
PURPOSE To develop an evidence-based clinical practice guideline for the use of exome and genome sequencing (ES/GS) in the care of pediatric patients with one or more congenital anomalies (CA) with onset prior to age 1 year or developmental delay (DD) or intellectual disability (ID) with onset prior to age 18 years. METHODS The Pediatric Exome/Genome Sequencing Evidence-Based Guideline Work Group (n = 10) used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence to decision (EtD) framework based on the recent American College of Medical Genetics and Genomics (ACMG) systematic review, and an Ontario Health Technology Assessment to develop and present evidence summaries and health-care recommendations. The document underwent extensive internal and external peer review, and public comment, before approval by the ACMG Board of Directors. RESULTS The literature supports the clinical utility and desirable effects of ES/GS on active and long-term clinical management of patients with CA/DD/ID, and on family-focused and reproductive outcomes with relatively few harms. Compared with standard genetic testing, ES/GS has a higher diagnostic yield and may be more cost-effective when ordered early in the diagnostic evaluation. CONCLUSION We strongly recommend that ES/GS be considered as a first- or second-tier test for patients with CA/DD/ID.

Eur J Hum Genet 2021; 29:930-939. [PMID: 33637888 PMCID: PMC8187681 DOI: 10.1038/s41431-021-00834-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 02/10/2021] [Indexed: 12/14/2022] Open
Abstract
Unsolicited findings (UFs) in clinical exome sequencing are variants that are unrelated to the initial clinical question the DNA test was performed for, but that may nonetheless be of medical relevance to patients and/or their families. There is limited knowledge about the impact of UFs on patients' lives. In order to characterise patient perceptions of the impact of an UF, we conducted 20 semi-structured face-to-face interviews with patients and/or their relatives to whom an UF predisposing to oncological disease (n = 10) or predisposing to a cardiac condition (n = 10) had been disclosed. We have identified a psychological, physical and financial aspect of the perceived impact of UF disclosure in exome sequencing. Actionability, understanding, patients' pre-test health and social context were influencing factors, according to our participants. Although most expressed considerable psychological impact initially, all but one participant would choose to undergo genetic testing again, knowing what they know now. These novel findings provide insight in patients' perspectives on the impact of UF disclosure. Our study highlights the value of incorporating patients' perceptions in UF disclosure policy.

Learning from scaling up ultra-rapid genomic testing for critically ill children to a national level. NPJ Genom Med 2021; 6:5. [PMID: 33510162 PMCID: PMC7843635 DOI: 10.1038/s41525-020-00168-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Accepted: 12/15/2020] [Indexed: 12/25/2022] Open
Abstract
In scaling up an ultra-rapid genomics program, we used implementation science principles to design and investigate influences on implementation and identify strategies required for sustainable “real-world” services. Interviews with key professionals revealed the importance of networks and relationship building, leadership, culture, and the relative advantage afforded by ultra-rapid genomics in the care of critically ill children. Although clinical geneticists focused on intervention characteristics and the fit with patient-centered care, intensivists emphasized the importance of access to knowledge, in particular from clinical geneticists. The relative advantage of ultra-rapid genomics and trust in consistent and transparent delivery were significant in creating engagement at initial implementation, with appropriate resourcing highlighted as important for longer term sustainability of implementation. Our findings demonstrate where common approaches can be used and, significantly, where there is a need to tailor support by professional role and implementation phase, to maximize the potential of ultra-rapid genomic testing to improve patient care.

Abstract
AbstractGenomics is rapidly being integrated into the routine care of children and families living with renal disease, principally as a diagnostic tool but also to direct therapy, identify at-risk relatives, and facilitate family planning. However, despite significant progress in understanding the genetic heterogeneity of inherited renal disease, the impact of genetic testing on parents and families of affected children is not well understood. This study aimed to investigate the experiences of families undergoing genetic testing, the psychosocial impact of receiving a genetic test result, and parent information and support needs. In-depth semistructured interviews were conducted with 26 parents of pediatric patients (<18 years of age) who had undergone genomic investigation for a suspected genetic renal disease at two tertiary pediatric nephrology services. Interviews were transcribed verbatim, coded, using NVivo software, and thematic analysis was undertaken. Key themes included emotional adjustment to a genetic diagnosis, the importance of parent-provider relationships, empowerment through social connection, and the value of family-centered care. Results highlighted the wide-ranging psychosocial impact of genetic testing on parents, as well as the importance of patient-support networks in enabling parents/families to cope and adapt. Targeted approaches to enhance communication of genetic information and the development of tailored resources to address parents' genetics and health service needs may lead to more satisfactory experiences of genetic testing.
