Understanding the potential of state-based public health genomics programs to mitigate disparities in access to clinical genetic services.

PURPOSE: State health agencies (SHAs) have developed public health genomics (PHG) programs that play an instrumental role in advancing precision public health, but there is limited research on their approaches. This study examines how PHG programs attempt to mitigate or forestall health disparities and inequities in the utilization of genomic medicine. METHODS: We compared PHG programs in three states: Connecticut, Michigan, and Utah. We analyzed 85 in-depth interviews with SHA internal and external collaborators and program documents. We employed a qualitative coding process to capture themes relating to health disparities and inequities. RESULTS: Each SHA implemented population-level approaches to identify individuals who carry genetic variants that increase risk of hereditary cancers. However, each SHA developed a unique strategy-which we label public health action repertoires-to reach specific subgroups who faced barriers in accessing genetic services. These strategies varied across states given demographics of the state population, state-level partnerships, and availability of healthcare services. CONCLUSION: Our findings illustrate the imperative of tailoring PHG programs to local demographic characteristics and existing community resources. Furthermore, our study highlights how integrating genomics into precision public health will require multilevel, multisector collaboration to optimize efficacy and equity.

Developing a genetic services assessment tool to inform quality improvement efforts in state genetic service delivery.

PURPOSE: The Institute of Medicine recommended the utilization of metrics to improve quality in health care, although they have rarely been used in genetics. This study developed and tested a set of metrics for a quality assessment tool for genetic services METHODS: A systematic review of literature, guidelines, and consensus statements identified candidate measures for a possible assessment tool. An expert panel conducted a modified Delphi technique to rank the metrics. Ratings were computed to generate a score for each metric, creating a set of metrics for consensus discussions, pilot testing, and feasibility testing in eight Midwestern states. RESULTS: The panel reduced 61 candidate metrics to 21 for pilot testing in two states, which further limited and refined the set to 16 metrics. These 16 were categorized into five domains: service capacity, access to care, data systems, performance reporting, and workforce. Further feasibility testing in one Regional Genetics Collaborative identified the tool's usefulness and barriers to implementation. CONCLUSIONS: These quality metrics for both clinical and public health genetics across the lifespan may help medical professionals and policymakers evaluate quality and cost-effectiveness of genetic services on a statewide basis and stimulate outcome-oriented, health services research in medical genetics and genomics.

Molecular and Clinical Opposite Findings in 11p15.5 Associated Imprinting Disorders: Characterization of Basic Mechanisms to Improve Clinical Management.

Silver-Russell and Beckwith-Wiedemann syndromes (SRS, BWS) are rare congenital human disorders characterized by opposite growth disturbances. With the increasing knowledge on the molecular basis of SRS and BWS, it has become obvious that the disorders mirror opposite alterations at the same genomic loci in 11p15.5. In fact, these changes directly or indirectly affect the expression of IGF2 and CDKN1C and their associated pathways, and thereby, cause growth disturbances as key features of both diseases. The increase of knowledge has become possible with the development and implementation of new and comprehensive assays. Whereas, in the beginning molecular testing was restricted to single chromosomal loci, many tests now address numerous loci in the same run, and the diagnostic implementation of (epi)genome wide assays is only a question of time. These high-throughput approaches will be complemented by the analysis of other omic datasets (e.g., transcriptome, metabolome, proteome), and it can be expected that the integration of these data will massively improve the understanding of the pathobiology of imprinting disorders and their diagnostics. Especially long-read sequencing methods, e.g., nanopore sequencing, allowing direct detection of native DNA modification, will strongly contribute to a better understanding of genomic imprinting in the near future. Thereby, new genomic loci and types of pathogenic variants will be identified, resulting in more precise discrimination into different molecular subgroups. These subgroups serve as the basis for (epi)genotype-phenotype correlations, allowing a more directed prognosis, counseling, and therapy. By deciphering the pathophysiological consequences of SRS and BWS and their molecular disturbances, future therapies will be available targeting the basic cause of the disease and respective pathomechanisms and will complement conventional therapeutic strategies.

Telegenetics: a systematic review of telemedicine in genetics services.

PURPOSE: Telemedicine is being increasingly used in many areas of health care, particularly to reduce the barriers that rural populations face in accessing health-care services. Telemedicine may also be effectively utilized in clinical genetics services-an application that has been termed "telegenetics." METHODS: A systematic review of the literature was conducted to identify studies of genetic consultations carried out through videoconferencing so as to determine whether conclusions can be drawn about the value of telegenetics. A total of 14 articles reporting data from 12 separate studies met the inclusion criteria. RESULTS: In a majority of these studies, patients received their telegenetics consultation at a local clinic or outreach center, from where they communicated via a synchronous video link with a genetics practitioner. All the studies reported high levels of patient satisfaction with telegenetics, and patients were generally more receptive to telegenetics than the genetics practitioners were. The studies had limitations of small sample sizes and lack of statistical analyses. CONCLUSIONS: This review suggests that telegenetics may be a useful tool for providing routine counseling and has the potential to evaluate pediatric patients with suspected genetic conditions. Prospective, fully powered studies of telegenetics that explore the accuracy of diagnoses and patient outcomes are needed to allow informed decisions to be made about the appropriate use of telemedicine in genetics service delivery.

It's about scientific secrecy, dummy: a better equilibrium among genomics patenting, scientific research and health care.

This paper offers a different pragmatic and patent-based approach to concerns regarding the negative effects of genetic-based patenting on advancing scientific research and providing adequate and accessible health care services. At the basis of this approach lies an explication of a mandatory provisional patented paper procedure (PPPA), designed for genetic-based patents and administered by leading scientific journals in the field, while officially acknowledged by the USPTO, and subsequently by other patent offices as well. It is argued that the uniqueness of PPPAs lies in subsequently mitigating the negative ramifications of genetic patents on scientific research and genetic-based health care services, while basing such mitigation on a patents' advocate viewpoint that neither discards the patent system nor jeopardizes its integrity.

[Personalized medicine: expectations, disappointments and hopes].

Impressive advances in the studies of human genome, identification of mutant genes of hereditary diseases and candidate genes of many chronic multifactorial diseases (MFD) laid the foundation of molecular medicine. Its characteristic features, such as the focus on individual prophylactic care, give reason to consider it as personalized predictive medicine (PPM). The fundamental concept behind PPM comprises the notion of genetic passport and its methodological basis is genetic testing (GT). Recent progress in PPM has been achieved due to the introduction of comprehensive genomic screening of associations. At the same time, the contribution of known individual genes to the development of MFD appears to be relatively insignificant which does not allow to identify the main causes of MFD. It gave rise to some scepsis as regards the value of genome as a source of information for practical medicine. Possibilities for the improvement of GT and conditions for the introduction of the available data into clinical practice are discussed. The necessity to attract clinicians to the work on PPM is emphasized. The development of unified MFD gene panels for clinical application and software for the evaluation and interpretation of GT results for doctors and patients is an indispensable condition for the use of PPM knowledge in the healthcare practice. The importance of solution of relevant ethical, juridical, and social issues is underscored.

Genetics in ophthalmology: equity in service provision?

BACKGROUND: Scientific advances in the understanding of the molecular biology of inherited eye conditions now allow more effective diagnosis and management for patients and families. For translation into clinical practice, it is vital that specialist services are developed with the necessary multi-disciplinary expertise, investigatory resources and organizational arrangements. We investigate the equity of specialist provision in the UK and make recommendations for service development. METHODS: A questionnaire survey was carried out of all providers of specialist genetic services in the UK. Results were analysed by provider, catchment population and Strategic Health Authority population. RESULTS: Nineteen specialist services were identified. Provision of annual out-patient clinics and medical consultant sessions varied widely with many small services lacking full multi-disciplinary teams. There was an 8-fold regional variation in patient activity. Across the UK, we estimated an annual shortfall of 1000 new patient referrals. CONCLUSIONS: There should be a national programme of strategic planning of specialist genetic ophthalmology services. Necessary elements will include service specifications and standards, overall number and configuration of services, models which maximize the efficiency of use of specialist genetics elements and education of specialist and general ophthalmologists in genetics elements of their specialty.

Quality genetic services for the population, now and in the future.

The possibilities for testing and screening for genes involved in inherited diseases or susceptibility to diseases have increased spectacularly. Combined with a revolution in the availability of sophisticated new technologies for testing, the question arises how will we be able to continue to provide quality services to our customers ? Who will provide these ? Will it be the centres, as we know them today, or will DTC take gradually over this service ? Will the quality criteria, as established today before tests are made available, still be applicable and how will these new services be able to contribute to an increasing and coordinated collection of global information on genetic diversity and on the pathogenic changes in the human genome? As stated in the Bioethics Convention of the European Council and explicited in the recent recommendations from the House of Lords of the UK on Genomic Medicine, we will need a major effort of the European Commission/of our governments, to implement a series of measures which will allow the correct and quality assured introduction into practice of the genetic knowledge that is being generated. Only then will all individuals and the scientific community be able to benefit from our services.

Rethinking the ethical principles of genomic medicine services.

Clinical genome and exome sequencing is currently used in only a small fraction of patients, yet large scale genomic initiatives are becoming more embedded in clinical services. This paper examines the ethical principles that should guide regulatory processes regarding consent and data sharing in this context. We argue that a genomic dataset administered by the health system carries substantial societal benefits, and that the collective nature of this initiative means that at least those patients who benefit from genome sequencing have an ethical obligation to share their health information. This obligation is grounded in considerations of fairness. Furthermore, we argue that the use of genomic data for the advancement of medical knowledge should be permitted without explicit consent and that international and other bodies should be granted access to these data, provided certain conditions are satisfied.

Quality in clinical genetics.

Application of quality improvement techniques to medical care has the potential to improve the quality of care, reduce variability in practice, and optimize medical and service outcomes and cost. While becoming more common in other specialties, clinical genetics is only beginning to address these issues. There are a number of challenges to the application of quality improvement to a specialty where rare and ultra-rare disorders are the rule rather than the exception. This article briefly reviews some of these challenges while introducing the articles in this issue of Seminars.

Identification and prioritization of quality indicators in clinical genetics: an international survey.

The range and demand for clinical genetic services will continue to grow, and now is an ideal time to assess current service quality. Based on the previous work of quality professional organizations such as the Institute of Medicine (IOM) and The Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) which is now known as The Joint Commission (TJC), an independent group of genetic and healthcare quality professionals (InheritQual) drafted and defined a list of potential quality indicators for clinical genetics. Perspectives on the appropriateness and the practicality of each indicator were surveyed and analyzed. The Quality Special Interest Group of the American College of Medical Genetics (ACMG) chartered the survey results. After measuring the degree of consensus, an expert panel was selected to review the quality indicators based on practicality and applicability. This expert panel comprised of members of the ACMG Quality Sig workgroup met for final consensus and developed a methodology to pilot these indicators.

Quality assurance in medical and public health genetics services: a systematic review.

As genetic services grow in scope, issues of quality assessment in genetic services are emerging. These efforts are well developed for molecular and cytogenetic testing and laboratories, and newborn screening programs, but assessing quality in clinical services has lagged, perhaps owing to the small work force and the recent evolution from a few large training programs to multiple training sites. We surveyed the English language, peer-reviewed literature to summarize the knowledge-base of quality assessment of genetics services, organized into the tripartite categories of the Donabedian model of "structure," "process," and "outcome." MEDLINE searches from 1990 to July 2008, yielded 2,143 articles that addressed both "medical/genetic screening and counseling" and "quality indicators, control, and assurance." Of the 2,143 titles, 131 articles were extracted for in-depth analysis, and 55 were included in this review. Twenty-nine articles focused on structure, 19 on process, and seven on outcomes. Our review underscored the urgent need for a coherent model that will provide health care organizations with tools to assess, report, monitor, and improve quality. The structure, process, and outcomes domains that make up the quality framework provide a comprehensive lens through which to examine quality in medical genetics.

Evidence-based medicine and practice guidelines: application to genetics.

The Professional Practice and Guidelines Committee of the American College of Medical Genetics has the responsibility of overseeing the development of guidelines for the practice of clinical genetics. In the past, most, if not all, guidelines were primarily based on expert opinion. However, recently the goal has become to develop guidelines that are more evidence-based, or at least, to recognize the level of evidence available to the authors of these documents. This article reviews the challenges that are faced by geneticists who are charged with the development of practice guidelines.

Statement on guidance for genetic counseling in advanced paternal age.

In 1996, a practice guideline on genetic counseling for advanced paternal age was published. The current document updates the state of knowledge of advanced paternal age effects on single gene mutations, chromosome anomalies, and complex traits.

Molecular genetic testing for ultra rare diseases: models for translation from the research laboratory to the CLIA-certified diagnostic laboratory.

Although the pace of gene discovery for rare genetic diseases has accelerated during the past decade, in part, due to the success of the Human Genome Project, translation of these discoveries to clinical utility has lagged behind. In particular, identification of the gene responsible for a Mendelian disorder immediately presents the opportunity for molecular genetics diagnostics to confirm clinical diagnoses, provide accurate genetic counseling information and recurrence risks, as well as carrier testing and prenatal diagnosis opportunities for families. To move these discoveries from a research setting to clinical utility, we describe two successful models for partnerships between research laboratories with Clinical Laboratory Improvement Amendments-certified clinical molecular diagnostic laboratories. Contrary to common misconceptions, molecular genetic testing for very rare diseases can be performed in a high-quality clinical setting in a financially self-sustaining or even profitable manner. Key elements to the success of these models include a Clinical Laboratory Improvement Act-certified diagnostic laboratory with a commitment to very rare genetic disease testing, active involvement of genetic counselors and clinical geneticists, and partnerships with research experts and patient support groups specific to each disease.

Consumer contribution to the delivery of genetic health services.

Clinical genetics services have been the focus of evaluation and guidelines since the 1970s. In this study we used consumer satisfaction as the evaluative measure with the aim being to seek feedback from consumers of a genetics service to inform quality measures for client-centered genetic services. In the first phase of the study issues were identified by consumers and health professionals around delivering genetics services and the priorities ranked into five themes: expectations, information, respect, privacy and logistics. These themes then formed the basis of a questionnaire that was distributed to consumers of a genetics service in Victoria, Australia. Three hundred ninety-seven out of 821 questionnaires were completed (49.8% response rate). More than 85% of consumers were satisfied in the theme of expectations, with the only issue being waiting times for genetic test results (68.6% satisfied). Over 83% of consumers were satisfied with the information received from the genetics service. The matter of interruptions during appointments was the only area in the theme of respect that rated less than 80% satisfactory (79.1%). In relation to privacy, consumers rated over 95% satisfaction. Logistics was the theme where satisfaction was lowest with ratings of less than 75% for issues such as availability of public transport to the clinic, parking and wheelchair access. Consumer satisfaction was related to the information received before and after consultations and also to the attitudes and behaviors of health professionals. These findings have implications for genetics services both in Australia and internationally and recommendations from the findings are outlined.

Ethical and legal issues in nutritional genomics.

Advances in the ability to study how common variations in genes affect the metabolism of drugs and foods suggest that genetic information about individuals is of increasing relevance to clinical practitioners, including registered dietitians. The acquisition, storage, and use of genetic information in nutrition counseling will pose difficult ethical and legal questions involving the maintenance of confidentiality, the right to privacy, and the risks of discrimination in decisions about insurance coverage and employment. In addition, genetic analysis of children poses new questions about the limits of parental authority. Although the field of nutritional genomics is in its infancy, it is appropriate for registered dietitians to begin now to fashion a code of conduct about the proper use of genetic information. Relevant legal topics, such as federal and state legislation and judicial decisions, are discussed.

The role of genetics in the provision of essential public health services.

States include genetics services among their public health programs, but budget shortfalls raise the question, is genetics an essential part of public health? We used the Essential Services of Public Health consensus statement and data from state genetics plans to analyze states' public health genetics programs. Public health genetics programs fulfill public health obligations: birth defects surveillance and prevention programs protect against environmental hazards, newborn screening programs prevent injuries, and clinical genetics programs ensure the quality and accessibility of health services. These programs fulfill obligations by providing 4 essential public health services, and they could direct future efforts toward privacy policies, research on communications, and rigorous evaluations.

A 'joint venture' model of recontacting in clinical genomics: challenges for responsible implementation.

Advances in genomics often lead healthcare professionals (HCPs) to learn new information, e.g., about reinterpreted variants that could have clinical significance for patients seen previously. A question arises of whether HCPs should recontact these former patients. We present some findings interrogating the views of patients (or parents of patients) with a rare or undiagnosed condition about how such recontacting might be organised ethically and practically. Forty-one interviews were analysed thematically. Participants suggested a 'joint venture' model in which efforts to recontact are shared with HCPs. Some proposed an ICT-approach involving an electronic health record that automatically alerts them to potentially relevant updates. The need for rigorous privacy controls and transparency about who could access their data was emphasised. Importantly, these findings highlight that the lack of clarity about recontacting is a symptom of a wider problem: the lack of necessary infrastructure to pool genomic data responsibly, to aggregate it with other health data, and to enable patients/parents to receive updates. We hope that our findings will instigate a debate about the way responsibilities for recontacting under any joint venture model could be allocated, as well as the limitations and normative implications of using ICT as a solution to this intractable problem. As a first step to delineating responsibilities in the clinical setting, we suggest HCPs should routinely discuss recontacting with patients/parents, including the new information that should trigger a HCP to initiate recontact, as part of the consent process for genetic testing.

DISCERN-Genetics: quality criteria for information on genetic testing.

Information currently available to the public is inadequate to support those deciding to consent to a genetic test. As genetic knowledge continues to evolve, more people will be forced to consider the complex issues raised by genetic testing. We developed and tested criteria to guide the production and appraisal of information resources produced for the public on genetic testing. Lay people with and without experience of a genetic condition, and providers and producers of health information appraised and listed the criteria they used to rate the quality of a sample of information on cystic fibrosis, Down's syndrome, familial breast cancer, familial colon cancer, haemochromatosis, Huntington's disease, sickle cell disease, and thalassaemia. These genetic conditions represent different populations, disease pathways, and treatment decisions. The information medium could be written, electronic, CD, audio or video. The quality criteria were tested iteratively (using the weighted kappa statistic) for the level of agreement between users applying successive drafts of the criteria to different samples of information. The final set of criteria consisted of 19 questions plus an overall quality rating. Chance corrected agreement (weighted kappa) among the appraisers for the overall quality rating was 0.61 (0.60-0.62). The criteria cover the scope of the information resources, information on the condition, the test procedure and results, decision making, and the reliability of the information. The DISCERN-Genetics criteria will guide the production and appraisal of information produced for the public, and will facilitate the involvement of the public in decisions around genetic screening and testing.
