How genomic information is accessed in clinical practice: an electronic survey of UK general practitioners

Non-genetic physicians' knowledge, attitudes and behavior towards medical genetics

To examine the knowledge, behavior, and attitudes toward medical genetics among obstetrics and gynecology, pediatrics, and neurology residents and specialists, who encounter the highest number of patients with specific genetic disorders, in their everyday practice. The cross-sectional study involved 182 nongenetic residents and specialists in the Republic of Croatia, who completed a validated online questionnaire anonymously and voluntarily. The questionnaire consisted of five groups of questions: general information, knowledge, behavior in practice, attitude toward genetic testing, and additional education in medical genetics. The median score for overall knowledge of medical genetics was 70.2% among obstetrician-gynecologists, 80.5% among pediatricians, and 76.7% among neurologists (P < 0.001, lowest median in obstetrician-gynecologists). When asked about their behavior in daily practice, around 90% of respondents admitted the possibility of not recognizing patients with genetic disorders, which is why more than 90% emphasized the need for additional education in medical genetics. In addition, the respondents showed a positive attitude toward genetic testing, but they did not feel educated enough to interpret the results of genetic testing. The results highlight the need for further genetic education of non-genetic health professionals, which would lead to greater confidence and ability to recognize patients with genetic disorders, select the appropriate genetic testing method and achieve more efficient communication with patients.

Embedding genomics across the NHS: a primary care perspective

Primary care remains the point of access to the NHS as well as having key roles in care coordination and prescribing. Therefore, embedding of genomic medicine in the NHS relies on successful implementation into the primary care landscape. Primary care is currently facing considerable challenges, including increasing numbers of patients and consultations per GP, multiple health conditions and polypharmacy, all contributing to increasing workload within a resource-constrained system. Although genomic medicine has enormous potential to benefit patients, its successful implementation demands alignment with existing skills and working practices, development of underpinning informatics infrastructure, integration into care pathways with consideration of commissioning and leadership. Here, we set out current initiatives and future strategies to support primary care colleagues in the delivery of genomic medicine, covering issues of workforce development and education, primary care leadership, and data and digital considerations.

Educational needs in diagnosing rare diseases: A multinational, multispecialty clinician survey

Purpose

Recognizing rare diseases (RDs) and initiating appropriate investigation and referral is critical for timely diagnosis. Unfortunately, patients with RDs experience significant diagnostic delays, potentially leading to inappropriate or harmful testing or treatment and disease progression.

Methods

A 14-question survey assessing clinician knowledge, experience, and educational needs in RDs was emailed to US and European Union Medscape member clinicians. The survey was available from April 1, 2021, through August 2, 2021.

Results

The respondents included 978 clinicians across 16 specialties. Two-thirds of the respondents considered RDs to be 50 to 500 times rarer than standard European Union or US definitions, and despite a point prevalence of 3.5% to 5.9%, 59% said they never or rarely (1× or 2× per year) see patients with RDs. Although 87% have been involved in an RD diagnosis, only 19% were mostly or very confident in making a diagnosis. In addition, 38% to 44% reported diagnostic barriers such as knowledge of signs/symptoms, time to investigate, guideline availability, test access, and referrals. Highest RD education preferences included a comprehensive online learning platform with current education and resources and case-based, text-based, and short formats (≤15 minutes) taught by world-renowned clinicians.

Conclusion

This research study identified RD knowledge gaps, highlighting the need for education to shorten the diagnostic odyssey, which can enable earlier referral and treatment.

General practitioners' (GPs) experience, attitudes and needs on clinical genetic services: a systematic review

OBJECTIVE

The proliferation and growing demands of genetic testing are anticipated to revolutionise medical practice. As gatekeepers of healthcare systems, general practitioners (GPs) are expected to play a critical role in the provision of clinical genetic services. This paper aims to review existing literature on GPs' experience, attitudes and needs towards clinical genetic services.

DESIGN

A systematic mixed studies review of papers published between 2010 and 2022.

ELIGIBILITY CRITERIA

The inclusion criterion was peer-reviewed articles in English and related to GPs' experience, views and needs on any genetic testing.

INFORMATION SOURCES

The PubMed, PsycINFO, Cochrane, EMBASE databases were searched using Mesh terms, Boolean and wildcards combinations to identify peer-reviewed articles published from 2010 to 2022. Study quality was assessed using Mixed Methods Appraisal Tool. Only articles that fulfilled the inclusion criteria were selected. A thematic meta-synthesis was conducted on the final sample of selected articles to identify key themes.

RESULTS

A total of 62 articles were included in the review. Uncertainty over GPs' role in providing genetic services were attributed by the lack of confidence and time constraints and rarity of cases may further exacerbate their reluctance to shoulder an expanded role in clinical genetics. Although educational interventions were found to increasing GPs' knowledge and confidence to carry out genetic tasks, varied interest on genetic testing and preference for a shared care model with other genetic health professionals have resulted in minimal translation to clinical adoption.

CONCLUSION

This review highlights the need for deeper exploration of GPs' varied experience and attitudes towards clinical genetic services to better facilitate targeted intervention in the adoption of clinical genetics.

Introducing genetic testing with case finding for familial hypercholesterolaemia in primary care: qualitative study of patient and health professional experience

BACKGROUND

Familial hypercholesterolaemia (FH) is a common inherited condition causing elevated cholesterol, premature heart disease, and early death. Although FH can be effectively treated, over 80% of people with FH remain undetected.

AIM

To explore patient and health professional experiences of introducing genetic testing with case finding for FH in primary care.

DESIGN AND SETTING

Qualitative study in UK general practice.

METHOD

Semi-structured interviews with a purposeful sample of 41 participants (24 patients and 17 health professionals) from eight practices, using an electronic case-finding tool (FAMCAT) to identify patients with higher likelihood of having FH and who were then offered diagnostic genetic testing in primary care. Data were analysed thematically.

RESULTS

While prior awareness of FH was low, patients were unsurprised to be identified as being at risk, and positive about being offered genetic testing by their practice. Patients not found to have FH were relieved, although some felt frustrated that their high cholesterol lacked a clear cause. Those confirmed to have FH largely expected and accepted this outcome. Practitioners saw detection of FH as an important new opportunity for preventive care. They found the case-finding tool easy to apply and noted patients' high uptake of genetic testing. While they were comfortable referring appropriate patients for further specialist management, GPs sought clearer definition about responsibility for identification and long- term care of FH in future care pathways.

CONCLUSION

Introducing genetic testing with electronic case finding for FH in primary care was positively experienced by patients and practitioners. Further development of this approach could help improve detection of FH in the general population.

Pharmacogenomic testing to support prescribing in primary care: a structured review of implementation models

The application of pharmacogenomics could meaningfully contribute toward medicines optimization within primary care. This review identified 13 studies describing eight implementation models utilizing a multi-gene pharmacogenomic panel within a primary care or community setting. These were small feasibility studies (n <200). They demonstrated importance and feasibility of pre-test counseling, the role of the pharmacist, data integration into the electronic medical record and point-of-care clinical decision support systems (CDSS). Findings were considered alongside existing primary care prescribing practices and implementation frameworks to demonstrate how issues may be addressed by existing nationalized healthcare and primary care infrastructure. Development of point-of-care CDSS should be prioritized; establishing clinical leadership, education programs, defining practitioner roles and responsibilities and addressing commissioning issues will also be crucial.

An online compendium of treatable genetic disorders

More than 4,000 genes have been associated with recognizable Mendelian/monogenic diseases. When faced with a new diagnosis of a rare genetic disorder, health care providers increasingly turn to internet resources for information to understand the disease and direct care. Unfortunately, it can be challenging to find information concerning treatment for rare diseases as key details are scattered across a number of authoritative websites and numerous journal articles. The website and associated mobile device application described in this article begin to address this challenge by providing a convenient, readily available starting point to find treatment information. The site, Rx-genes.com (https://www.rx-genes.com/), is focused on those conditions where the treatment is directed against the mechanism of the disease and thereby alters the natural history of the disease. The website currently contains 633 disease entries that include references to disease information and treatment guidance, a brief summary of treatments, the inheritance pattern, a disease frequency (if known), nonmolecular confirmatory testing (if available), and a link to experimental treatments. Existing entries are continuously updated, and new entries are added as novel treatments appear in the literature.
