Dysphagia (swallowing difficulty) is a complex condition associated with adverse clinical outcomes, including malnutrition, dehydration, aspiration pneumonia, prolonged hospitalisation and reduced quality of life. Effective dysphagia management requires person-centred, evidence-informed care delivered through coordinated multidisciplinary service models across acute, rehabilitation, long-term care, and community settings. Healthcare professionals (HCPs) play a central role in dysphagia service delivery. However, variability in training, resources, interprofessional collaboration, and organisational structures may influence care quality. A comprehensive synthesis of HCPs’ attitudes, and perceived barriers and enablers to dysphagia management is needed to inform workforce development and service improvement.
This mixed-methods systematic review will be conducted using the Joanna Briggs Institute (JBI) convergent integrated approach. Six bibliographic databases (PubMed, CINAHL, Embase, PsycINFO, Web of Science, and the Cochrane Library) will be searched for primary studies published between 1 January 2012 and 1 June 2025. Studies published in English, Maltese, Italian, French, and Polish will be eligible. Targeted organisational reports from the Royal College of Speech and Language Therapists (RCSLT), American Speech-Language-Hearing Association (ASHA), National Institute for Health and Care Excellence (NICE), World Health Organization (WHO), and European Society for Swallowing Disorders (ESSD) will also be searched. Two reviewers will independently screen, extract, and appraise studies. Methodological quality will be assessed using the Mixed Methods Appraisal Tool (MMAT). Quantitative data will be transformed into textual descriptions and integrated with qualitative findings to produce synthesised themes.
This review will provide an integrated understanding of professional-level and system-level influences on dysphagia service delivery. Findings are expected to inform workforce education, interprofessional collaboration, organisational policy, and person-centred care frameworks in dysphagia management.

Dysphagia is a multifactorial clinical condition that significantly affects nutritional status, respiratory health, and overall wellbeing.1 It may arise from neurological disorders (e.g., stroke, Parkinson’s disease, multiple sclerosis), structural abnormalities, head and neck cancer and its treatment, and age-related physiological changes. Dysphagia management typically spans screening and early identification,2 comprehensive assessment,3,4 implementation of compensatory and rehabilitative strategies,5–7 medical and nutritional interventions,8,9 and ongoing monitoring.
Service delivery models for dysphagia vary across healthcare systems10–14 due to differences in workforce structures, professional scope of practice, infrastructure, and policy environments.15 Management commonly involves speech and language therapists (SLTs),16 nurses,17 physicians,18 dietitians,19 occupational therapists,20 physiotherapists21 and pharmacists.22 Effective dysphagia care depends not only on clinical competence but also on adequate training, access to instrumental assessments, interdisciplinary communication, governance structures, and organisational resources. Furthermore, person-centred decision-making is essential, particularly where recommendations for example texture-modified diets23 or thickened liquids, may influence autonomy, quality of life, and patient experience.24
To enhance dysphagia care, it is essential to explore the perceptions and experiences of HCPs who work collaboratively to support individuals living with dysphagia.25 Given the collaborative nature of dysphagia management, it is critical to recognise the contributions of all HCPs involved in patient care.26 Gaining insight into these perspectives will help identify current practices, existing gaps in practice, improve multidisciplinary care and underscore the evolving role of SLTs in addressing dysphagia service delivery. Moreover, it can provide valuable information to inform strategies that can improve care quality and efficiency. The knowledge and perspectives of these professionals will offer a comprehensive understanding of the factors that influence service delivery, highlighting both shared and discipline-specific challenges.
Understanding HCPs attitudes, as well as perceived barriers and enablers to dysphagia management, is essential to strengthening service delivery.25 Mixed-methods synthesis enables integration27 of quantitative evidence describing patterns and prevalence with qualitative evidence that captures contextual and experiential dimensions. By synthesising current evidence, this review aims to identify modifiable workforce and system-level factors influencing dysphagia service delivery.28
This protocol was developed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P)29 statement. The completed PRISMA-P checklist and search strategies will be made available on OSF repository.
The systematic review is registered with PROSPERO (CRD42022323414). PROSPERO registration constitutes a registry record and does not represent publication or peer review.
A mixed-methods systematic review (MMSR) will be conducted using the Joanna Briggs Institute (JBI) convergent-integrated approach.27 This approach is appropriate where the review question can be addressed by both qualitative and quantitative evidence and where integrated findings are required.
Eligibility criteria were informed by the Population–Phenomenon of Interest–Context (PICo) framework.
Studies will be included if they:
• Are primary research (quantitative, qualitative, or mixed-methods);
• Include HCPs involved in dysphagia management;
• Report HCPs’ attitudes, perceived barriers, and/or enablers related to dysphagia management or service delivery;
• Are published after 1 January 2012
• Are available in English, Maltese, Italian, French, or Polish.
The eligibility window was selected to ensure relevance to contemporary dysphagia service delivery models, evolving professional roles, and current healthcare systems.
Studies will be excluded if they are:
• Reviews, overviews of reviews, editorials, letters, commentaries, or opinion pieces;
• Animal studies;
• Studies including only students;
• Studies focusing exclusively on patients or family caregivers without reporting HCP data;
• Studies not addressing attitudes, barriers, or enablers to dysphagia management.
The following databases will be searched:
Search strategies will combine controlled vocabulary and free-text terms related to dysphagia, healthcare professionals, attitudes, barriers, enablers, and service delivery.
In addition to bibliographic databases, targeted organisational reports will be searched to reduce publication bias and capture practice-relevant evidence. These will include resources and reports from:
• Royal College of Speech and Language Therapists (RCSLT)
• American Speech-Language-Hearing Association (ASHA)
• National Institute for Health and Care Excellence (NICE)
• World Health Organization (WHO)
• European Society for Swallowing Disorders (ESSD)
Reference lists of included studies will be screened for additional eligible records.
All identified records will be imported into Rayyan30 for screening. Two reviewers will independently screen titles and abstracts, followed by full-text screening. Disagreements will be resolved through discussion or consultation with a third reviewer. A PRISMA flow diagram will summarise the selection process.
A standardised extraction form will be developed and piloted. Extracted data will include:
• Study characteristics (author, year, country)
• Healthcare profession(s) and setting
• Study design and methods
• Sampling approach
• Key findings related to attitudes, barriers, and enablers
• Organisational and service delivery context
Data extraction will be conducted independently by two reviewers, with discrepancies resolved by consensus.
Risk of bias and methodological quality will be assessed using the Mixed Methods Appraisal Tool (MMAT),31 which enables the appraisal of qualitative, quantitative, and mixed-methods studies. Appraisal will be conducted at the study level. Two reviewers will independently assess methodological quality, with disagreements resolved through discussion or consultation with a third reviewer where necessary.
Quality appraisal results will be presented in tables and summarised narratively. Studies will not be excluded based on methodological quality. However, risk of bias assessments will inform interpretation of findings and the strength of conclusions drawn from the integrated synthesis, consistent with the JBI convergent integrated approach.
Potential meta-biases will be addressed through comprehensive search strategies across multiple databases and screening of reference lists of included studies. Grey literature will be considered where appropriate to reduce publication bias. Studies published in English, Maltese, Italian, French, and Polish will be included to minimise language bias. Selective reporting within studies will be considered as part of the methodological quality appraisal using the MMAT. Transparency in study selection and reporting will follow PRISMA guidance.
The review will follow the JBI convergent-integrated approach.32
Qualitative findings will be synthesised using thematic synthesis.33 Quantitative findings will be transformed into textual descriptions (“qualitised”) to enable integration with qualitative evidence.27 Integrated themes will be generated through iterative coding and collaborative review among the research team.
Synthesised findings will be organised to reflect individual, team-level, organisational, and system-level influences on dysphagia service delivery where supported by the data.
Confidence in the cumulative evidence will be assessed narratively, considering methodological quality (MMAT appraisal), consistency of findings across studies, and richness of qualitative and quantitative evidence contributing to each theme. Due to the mixed-methods design, formal grading approaches such as GRADE are not considered fully appropriate. Greater confidence will be attributed to findings supported by multiple studies of higher methodological quality and consistent evidence across study designs.
This protocol describes a mixed-methods systematic review to synthesise HCPs attitudes, and perceived barriers and enablers to dysphagia management across care settings. The review will generate an integrated understanding of workforce, organisational, and system-level determinants influencing dysphagia service delivery, as well as contextual factors shaping implementation within healthcare environments. A distinctive contribution is the application of the JBI convergent-integrated approach to combine qualitative and quantitative evidence, enabling identification of multi-level influences and theoretically informed insights that may guide evidence-based service improvement and implementation strategies in dysphagia care.
This review will provide the first comprehensive mixed-methods synthesis of HCPs attitudes, barriers, and enablers to dysphagia management across disciplines and care settings. Using the JBI convergent-integrated approach, it adopts a systems-oriented perspective to examine how individual, team, organisational, and structural factors influence dysphagia service delivery.
By integrating qualitative and quantitative evidence, the review will identify both the prevalence of reported determinants and the contextual mechanisms shaping practice. It recognises that dysphagia management is embedded within interconnected systems, including clinician knowledge and beliefs, interprofessional collaboration, organisational capacity, and broader policy environments.
Synthesising evidence across these levels will help identify priority targets for service improvement and inform theoretically grounded implementation strategies that are responsive to contextual variation across healthcare systems.
Findings from this review will extend beyond descriptive reporting of barriers and enablers to inform system service development. By mapping determinants across workforce, organisational, and structural domains, the review may support the design of implementation strategies that align with integrated care principles.
At the workforce level, findings may inform competency frameworks, targeted continuing professional development, and interprofessional education models that strengthen shared understanding of dysphagia risk management and person-centred decision-making.
At the organisational level, the review may identify modifiable structural factors, such as referral pathways, access to instrumental assessment, documentation standards, communication protocols, and governance mechanisms that influence service consistency and accountability.
At a policy level, findings may contribute to identifying enabling conditions for sustainable dysphagia service delivery, including protected clinical time, workforce planning, equitable resource distribution, and integration across acute and community care interfaces.
By situating dysphagia management within broader implementation and integrated care frameworks, the review may generate insights relevant to health system strengthening and quality improvement initiatives.
This synthesis will highlight key gaps in both theory and evidence. Future research may build on these findings by applying implementation science frameworks, such as the Consolidated Framework for Implementation Research (CFIR)34 or the Theoretical Domains Framework (TDF),35,36 to design and evaluate context-sensitive strategies aimed at strengthening dysphagia service delivery.
Subsequent studies may incorporate mixed-methods or prospective designs to examine the relationship between professional attitudes and measurable patient-level outcomes, including safety indicators, nutritional status, hospital utilisation, and patient-reported experience. Comparative international research may further clarify how contextual factors and underlying mechanisms interact to influence dysphagia management across different healthcare systems.
Dysphagia management is embedded within complex healthcare systems characterised by interprofessional interdependence, organisational constraints, and changing policy contexts. By synthesising healthcare professionals’ attitudes, barriers, and enablers through a theoretically informed mixed-methods approach, this review aims to generate actionable, system-sensitive insights that support implementation of consistent, person-centred, and equitable dysphagia service delivery.
