Genetic and genomic practices are now central to modern healthcare. As next-generation sequencing becomes more affordable and accessible, demand for genetic services is rising rapidly. However, there is a critical shortage of clinical geneticists and genetic counsellors. As a result, nurses and allied health professionals (AHPs) must step into expanded roles. A recent systematic review published in the European Journal of Human Genetics examines strategies to help these professionals integrate genetics into everyday practice.
Why Genetic Literacy Matters for Allied Health Professionals
Allied health professionals — including nurses, speech-language pathologists, occupational therapists, audiologists, physiotherapists, and optometrists — interact with patients before genetic specialists do. They observe early signs of genetic conditions. Furthermore, they support families after a genetic diagnosis is made. Yet many of these professionals lack confidence and knowledge in genetics.
A study of 3,600 American AHPs found that 70% had already discussed the genetic basis of health concerns with patients. Despite this, significant gaps in training and resources remain across the profession. Addressing these gaps is not optional. It is essential for improving patient outcomes through early identification and personalised care.
The Role of Next-Generation Sequencing
Next-generation sequencing, including whole genome and exome sequencing, has transformed diagnostics. It offers faster results, lower costs, and greater clinical access. Consequently, genetic data now informs diagnosis, prognosis, and targeted therapies. Non-genetic clinicians must understand how to interpret and act on this information in their daily practice.
Key Barriers to Genetics Integration in Clinical Practice
Multiple barriers prevent AHPs and nurses from fully engaging with genetic practices. Understanding these barriers is the first step toward effective solutions.
Lack of knowledge and training ranks as the most commonly reported barrier. Many professionals want to learn more about genetics. However, they cannot access reliable resources tailored to their discipline. Additionally, genetics training is often absent from undergraduate and postgraduate curricula.
Uncertainty about professional roles also creates hesitation. Professionals are often unsure whether discussing genetics falls within their scope of practice. This uncertainty leads to missed opportunities for genetic referral or counselling.
Limited support systems further compound the problem. Many AHPs lack access to collaborative networks, expert guidance, or institutional frameworks that could support genetics engagement. Without such systems, even willing professionals find it difficult to act confidently.
Emotional concerns present another challenge. Professionals worry about the potential psychological impact of delivering genetic diagnoses to patients and families. This fear discourages open genetic conversations.
Empirical Strategies That Support Genetic Practices
The systematic review analysed 28 studies published from 2020 onward, drawing from six major databases. Several tested strategies showed positive results in improving genetic integration among nurses and AHPs.
Education and Online Learning
Web-based learning tools and online platforms were among the most widely used strategies. Seven studies used digital education to improve genetic literacy. These platforms provided flexible access to content, supporting professionals across different practice settings. Moreover, they allowed self-paced learning, which suits busy clinical schedules.
Workshops and Case-Based Learning
Workshops offered practical, interactive learning experiences. Case-based learning approaches proved especially effective. They allowed professionals to apply genetic knowledge directly to clinical scenarios. Three studies demonstrated that case-based methods improved both theoretical understanding and practical application of genetics.
Curriculum Development
Updating undergraduate and postgraduate curricula to include genetics is another proven strategy. Three studies found that curriculum reform led to measurable improvements in genetic competencies among nursing students and faculty. Integrating genetics into standard educational pathways ensures that future professionals enter practice better prepared.
Leadership Development
Leadership support plays a critical role in driving change. Involving senior staff and nurse leaders in genomics integration helps build a culture that values genetics. One study demonstrated that leadership development programs directly contributed to broader adoption of genetic practices across clinical teams.
Conceptual Strategies for Genomic Literacy
Beyond tested methods, the review identified a wide range of conceptual strategies. These are proposed approaches that have not yet been formally evaluated, but offer promising directions for future development.
Interdisciplinary Collaboration
Nine studies proposed interdisciplinary collaboration as a key strategy. Cross-professional teamwork helps share knowledge, build confidence, and reduce professional silos. Bringing together nurses, AHPs, and genetic specialists creates richer learning environments and better patient care.
Tailored Educational Resources
Generic training rarely meets the needs of specific professional groups. Tailored resources — designed for audiologists, occupational therapists, or speech pathologists — address role-specific knowledge gaps. Four studies highlighted this approach as a priority, particularly for professions with limited genetics exposure.
Professional Development and Policy Advocacy
Professional development opportunities, genomic literacy toolkits, and evaluation tools were frequently recommended across studies. In addition, policy advocacy emerged as a key driver. Aligning institutional and national strategies with genomics goals secures funding, standardises expectations, and promotes systemic change. Five studies emphasised advocacy efforts, including financial investment and alignment with international genomic frameworks.
Mapping Strategies to the Theoretical Domains Framework
The Theoretical Domains Framework (TDF) identifies 14 domains that influence behaviour change. Researchers mapped both empirical and conceptual strategies onto the TDF to understand which behavioural areas received the most attention — and which did not.
Most Represented Domains
Knowledge was the most frequently targeted domain across both strategy types (empirical: 10 studies; conceptual: 12 studies). This reflects the field’s strong focus on education as a primary intervention.
Social/Professional Role and Identity and Social Influences were also well represented. Strategies targeting these domains included peer mentoring, genomic champions, leadership involvement, and interprofessional training.
Environmental Context and Resources received moderate attention, primarily through the provision of online tools, toolkits, and accessible learning platforms.
Underrepresented Domains
Critically, several TDF domains received little to no attention in current strategies. These include Intentions, Reinforcement, Optimism, Emotion, and Goals. These domains relate to motivation, emotional responses, and personal values — all of which drive lasting behaviour change. Their absence signals a major gap in the current approach to genetics integration.
Gaps and Future Research Directions
The review reveals that most implementation strategies focus narrowly on knowledge. While education is important, behaviour change requires a broader, multi-domain approach. Addressing motivation, emotions, and professional identity alongside knowledge is essential for sustainable change.
Moreover, many conceptual strategies lack evaluation. Without rigorous testing, it is impossible to know what works. Future research must therefore assess the feasibility and effectiveness of these proposed approaches. It should also explore underrepresented TDF domains to produce more comprehensive and impactful interventions.
Additionally, most included studies focused on nurses, with fewer covering AHPs such as occupational therapists, optometrists, and speech pathologists. Broadening research to encompass all relevant professions will ensure no group is left behind in the push toward genetic literacy.
Conclusion
Integrating genetics into allied health and nursing practice is both urgent and achievable. This systematic review confirms that education, leadership, and interdisciplinary collaboration can drive meaningful change. Nevertheless, current strategies remain incomplete. They overlook key behavioural domains and many proposed approaches await formal testing. Closing these gaps will require targeted research, updated curricula, tailored resources, and strong policy support. Together, these efforts will build a healthcare workforce ready to meet the genetic challenges of modern medicine.
