Prophylactic swallowing therapy for patients with head and neck cancer: A three-arm randomized parallel-group trial.

BACKGROUND: Intensive prophylactic swallowing therapy can mitigate dysphagia in patients with oropharyngeal (OP) SCC, however, presents service challenges. This trial investigated the clinical efficacy of three service models delivering prophylactic swallowing therapy during (chemo)radiotherapy ([C]RT). METHODS: Patients (n = 79) with OPSCC receiving (C)RT were were randomized to: (a) clinician-directed face-to-face therapy (n = 26); (b) telepractice therapy via "SwallowIT" (n = 26); or (c) patient self-directed therapy (n = 27). Swallowing, nutritional, and functional status were compared at baseline, 6-weeks, and 3-months post-(C)RT. Patients' perceptions/preferences for service-delivery were collated posttreatment. RESULTS: Service-delivery mode did not affect clinical outcomes, with no significant (P > .05) between-group differences or group-by-time interactions observed for swallowing, nutrition, or functional measures. Therapy adherence declined during (C)RT in all groups. SwallowIT and clinician-directed models were preferred by significantly (P = .002) more patients than patient-directed. CONCLUSIONS: SwallowIT provided clinically equivalent outcomes to traditional service models. SwallowIT and clinician-directed therapy were preferred by patients, likely due to higher levels of therapy support.

Experiences of communication changes following spinal cord injury: a qualitative analysis.

Purpose: Voice and communication changes can occur following cervical spinal cord injury due to dysfunction of the respiratory and phonatory subsystems. Few studies have explored the "lived experience" of communication changes post cervical spinal cord injury. Furthermore, the impacts of these changes on community activity/participation and requirements for psychosocial adjustment have not been well-elucidated. The current study explored the experience of communication changes in non-ventilated individuals following cervical spinal cord injury, using a biopsychosocial framework.Materials and Methods: Semi-structured interviews were conducted with 14 community-dwelling non-ventilated individuals with cervical spinal cord injury. Thematic analysis was undertaken using an inductive approach. Themes were subsequently coded against domains of the World Health Organization International Classification of Functioning Disability and Health model, using established linking rules.Results: Four main themes were identified: (1) how communication has changed; (2) difficulties getting the message across, (3) the multifactorial impact of communication changes on everyday life; and (4) strategies/support to adjust to communication changes. Communication changes had multifaceted effects on participants' functioning, and were represented equally across the Body Functions (12 codes), Activities/Participation (12 codes), and Environmental Factors (11 codes) domains of the model.Conclusions: Individuals with cervical spinal cord injury perceive and experience meaningful changes on communication function post-injury, with salient impacts to daily-living and social participation.IMPLICATIONS FOR REHABILITATIONAs a result of communication changes post-injury, individuals with cervical spinal cord injury experience several challenges across a variety of domains in daily lifeThe current study highlights the benefit of using a biopsychosocial framework, such as The International Classification of Functioning, Disability and Health (ICF), to consider the complex and diverse impact of communication changes on the functioning of individuals with cervical spinal cord injury, as well as the influence of environmental factors, on rehabilitation planningThe current data demonstrates the need for increased involvement of speech-language pathologists as core members of the multidisciplinary team, and for acute awareness by all health professionals of the potential impact of communication changes on rehabilitation and psychosocial adjustment in individuals with cervical spinal cord injury.

A prospective examination of mask anxiety during radiotherapy for head and neck cancer and patient perceptions of management strategies.

INTRODUCTION: Distress related to wearing an immobilisation mask for radiotherapy treatment (RT) is a common experience for the person undergoing RT for head and neck cancer (HNC). Described as 'mask anxiety', there is little known about the patterns of this distress through the course of the treatment or what strategies are being used by people to help alleviate mask anxiety. METHODS: The study used a prospective cohort design to examine the patterns of patient-reported mask anxiety during the course of RT, using a modified Distress Thermometer (DT) and a survey to explore strategies patients used to assist their mask anxiety. RESULTS: Thirty-five participants, who identified as experiencing mask anxiety, were followed throughout RT treatment. At baseline, females were more likely to experience higher mask anxiety (P = 0.03). Across the course of treatment, mask anxiety significantly (P < 0.001) reduced within the total cohort. In 72% of participants, the level of initial distress was found to reduce over time. Only 22% experienced mask anxiety that remained constant. Few (6%) experienced an increase in mask anxiety across the course of RT. Participants reported relying on intervention from health professionals, self-taught strategies, music, visualisation and medication to manage their mask anxiety. CONCLUSIONS: Due to its high prevalence and variable patterns over time, it is recommended that routine screening for mask anxiety be implemented as standard care throughout the course of RT for HNC. Multiple, diverse strategies are being used by patients and studies are needed to develop effective interventions for managing mask anxiety.

Practices, knowledge and inter-professional relationships between speech pathologists and radiation therapists managing patients with head and neck cancer.

INTRODUCTION: This study examined knowledge and practices of speech pathologists (SPs) and radiation therapists (RTs) regarding plan optimisation for head and neck cancer (HNC) patients, and the potential impacts on swallowing function. The secondary aim was to explore the level of interaction occurring between these professional groups within cancer centres. METHODS: Two electronic surveys, with matched questions for SPs and RTs, explored: service/institutional demographics; clinician awareness, practices regarding plan optimisation to swallowing structures and; relationships and interactions between SPs and RTs in the management of HNC patients. Participant recruitment occurred through specialist professional networks with additional snowball sampling. Data were analysed with descriptive statistics and thematic analysis. RESULTS: A total of 32 SPs and 41 RTs completed surveys. All SPs and 50% of RTs were aware of dose-dysphagia relationships, though SPs rarely used dosimetric information to inform patient management. Only 33% of RTs indicated that their centres actively constrain dose to swallowing structures, reporting that staffing skill mixtures and lack of prescription by the treating RO were restrictive factors. Both SPs and RTs acknowledged the importance of collaborating with colleagues (SPs/RTs) and felt they could assist their colleagues in devising patient management plans, though current collaboration/interaction was minimal. CONCLUSIONS: Levels of awareness were found to be higher in SP group. Despite high levels of awareness, limited use of swallowing structure dose constraints and hence dosimetric information specific to swallowing was rarely used to optimise/guide multidisciplinary HNC acute care. Opportunities for enhanced collaboration between SPs and RTs should be considered.

Dysphagia optimized radiotherapy to reduce swallowing dysfunction severity in patients undergoing treatment for head and neck cancer: A systematized scoping review.

This study involved a systematized scoping review to coalesce current evidence on dysphagia outcomes achieved through active sparing of the swallowing structures in patients receiving radiotherapy for head and neck cancer. Eligible publications between 2007 and 2017 were reviewed and synthesized regarding participant demographics, treatment regimens, swallowing structures chosen for optimization, dosimetric constraints, and dysphagia measures. Nine prospective cohort studies were included. Key structures routinely spared included pharyngeal constrictor muscles (PCMs), glottic larynx (GL), supraglottic larynx (SGL), and esophageal inlet muscle. Shorter enteral feeding times and reductions in Common Terminology Criteria for Adverse Event (CTCAE) grade 3 dysphagia toxicity were observed when dose to the larynx (GL and SGL) and PCMs was constrained to < 50 and < 60 Gy, respectively. Emerging evidence supports "active" sparing of the swallowing structures at the time of radiotherapy planning to reduce dysphagia severity, with no compromise to planning target volumes and locoregional control rates.

Impact of carbonation on neurogenic dysphagia and an exploration of the clinical predictors of a response to carbonation.

BACKGROUND: The need for effective compensatory strategies in neurogenic dysphagia management has led to the exploration of sensory enhancement strategies (SES), such as carbonated liquids. Despite some positive findings, evidence related to the efficacy of carbonation as an SES is limited. AIMS: To determine if carbonated thin liquids reduced dysphagia symptoms and to explore clinical factors associated with response to carbonation. METHODS & PROCEDURES: Participants (n = 29) with neurogenic dysphagia demonstrating deep penetration or aspiration on thin liquids during videofluoroscopic swallow studies (VFSS) completed a set protocol: discrete sips of non-carbonated thin fluids (DS-NC) followed by discrete sips of carbonated thin fluids (DS-C) and then consecutive sips of carbonated fluids (CS-C). The impact of carbonation was identified through changes to swallow physiology (videofluoroscopy dysphagia scale-VDS) and depth of airway compromise (penetration-aspiration scale-PAS). Demographic variables including genetic taste type, cranial nerve function and key results from the VDS were examined for association with carbonation response using both individual parameter analysis and exploratory cluster analysis. OUTCOMES & RESULTS: Significant (p < 0.05) improvements in PAS scores were noted in DS-C and CS-C conditions compared with DS-NC. Total VDS score was also significantly (p < 0.05) reduced (i.e., improved function) in the DS-NC condition. Individual variability in response to carbonation was noted and no clear clinical factors associated with carbonation response in the current set of parameters were identified. CONCLUSION & IMPLICATIONS: Findings support that carbonated thin fluids sometimes result in neurogenic dysphagia symptom reduction. However, identifying the clinical characteristics of patients who may benefit from trials of carbonation needs further investigation.

Economic Analysis of a Three-Arm RCT Exploring the Delivery of Intensive, Prophylactic Swallowing Therapy to Patients with Head and Neck Cancer During (Chemo)Radiotherapy.

Research advocates for the use of intensive, prophylactic swallowing therapy to help reduce the severity of dysphagia in patients receiving (chemo)radiotherapy ([C]RT) for head/neck cancer (HNC). Unfortunately, the intensity of this therapy, coupled with growing patient numbers and limited clinical resources, provides challenges to many international cancer facilities. Telepractice has been proposed as a potential method to provide patients with greater support in home-practice, whilst minimising burden to the health service. This study investigated the clinical and patient-attributable costs of delivering an intensive, prophylactic swallowing therapy protocol via a new telepractice application "SwallowIT" as compared to clinician-directed FTF therapy and independent patient self-directed therapy. Patients (n = 79) with oropharyngeal HNC receiving definitive (C)RT were randomised to receive therapy via a: clinician-directed (n = 26), patient-directed (n = 27), or SwallowIT-assisted (n = 26) model of care. Data pertaining to health service costs (service time, consumables, therapy resources), patient-attributable costs (travel and wages) and patient-reported health-related quality of life (QoL) (AQoL-6D) were collected. SwallowIT provided a cost-efficient model of care when compared to the clinician-directed model, with significant cost savings to both the health service and to HNC consumers (total saving of $1901.10 AUD per patient; p < 0.001). The SwallowIT model also proved more cost-effective than the patient-directed model, yielding clinically significantly superior QoL at the end of (C)RT, for comparable costs. Overall, when compared to the alternate methods of service-delivery, SwallowIT provided a financially viable and cost-effective method for the delivery of intensive, prophylactic swallowing therapy to patients with HNC during (C)RT.

Research Engagement and Activity in an Allied Health Workforce Insights into Departmental and Organisational Strategies.

OBJECTIVE: Clinical environments that support and encourage research assist the development of research capacity and engagement amongst staff. Unfortunately, little information exists regarding departmental- and organisational-level strategies being used to encourage research capacity building within the allied health (AH) workforce. The current study used a qualitative approach to examine the nature of research engagement and activity occurring across AH departments within a large Australian public hospital and health service. METHODS: Twenty-two AH departments from five sites/services provided details on research capacity building activities within their departments. Responses were aggregated and then examined thematically using an inductive approach. The number of departments reporting content against each theme category or subcategory was analysed descriptively. RESULTS: A culture of research engagement was identified in over 90% of departments, with over 80% producing research outputs. Content analysis identified key strategies being used to (a) stimulate active staff engagement with with/in research, (b) support research activity, and (c) conduct research within networks and partnerships. CONCLUSIONS: AH departments in the current study engaged in multiple strategies to help build the research capacity of their staff. The findings highlight structures, processes, and systems that can be employed by departments at an organisational level to help support AH research capacity building.

Exploring the prevalence and experience of mask anxiety for the person with head and neck cancer undergoing radiotherapy.

INTRODUCTION: While use of a thermoplastic mask during radiotherapy (RT) treatment for head and neck cancer (HNC) is an essential component of safe patient care, there is little understanding of the extent to which this evokes anxiety (i.e. "mask anxiety") for the person undergoing treatment. METHODS: A mixed method, convergent design was used to examine the prevalence and experience of mask anxiety using two clinical cohorts. In phase one, a cohort of 100 patients undergoing RT for HNC were assessed for self-perceived mask anxiety using a modified distress thermometer screening tool. In phase two, a separate cohort of 20 patients who identified as having mask anxiety participated in individual interpretative descriptive interviews to explore the nature of their experience. RESULTS: In phase one, 26% of participants self-identified as being anxious about the use of a thermoplastic mask. In phase two thematic analysis of the interviews revealed two over-arching themes relating to the person's experience of mask anxiety: contributors to the mask anxiety (vulnerability, response to experience and expectations); and how the person was going to manage the mask anxiety during treatment (strategies and mindset). CONCLUSIONS: Mask anxiety impacted a quarter of participants undergoing radiotherapy for HNC. In line with the themes elicited from the participants, implementation of routine screening to ensure early identification, and patient education to assist preparation for wearing the mask during RT are strategies that could improve current management of mask anxiety.

Application of telepractice for head and neck cancer management: a review of speech language pathology service models.

PURPOSE OF REVIEW: Head and neck cancer (HNC) is a complex and heterogeneous disease, requiring specialist intervention from a multidisciplinary team including speech language pathology (SLP). Unfortunately, multiple patient and service-related challenges exist which currently limit equitable access to SLP support for all individuals. This review highlights the existing evidence for different telepractice models designed to help patients and services optimize management of swallowing and communication disorders arising from HNC. RECENT FINDINGS: Emerging evidence exists for using computerized screening to enhance the identification of treatment-related toxicities and assist referrals to services, including SLP. Asynchronous telepractice applications are being used to assist delivery of intensive home-based dysphagia therapy, whereas videoconferencing can offer a feasible and effective method to support ongoing management for patients with limited access to local specialist SLP services. Patient and clinician satisfaction with all models has been high. SUMMARY: SLP services can be redesigned to incorporate a range of telepractice models to optimize clinical care at different stages of the HNC survivorship pathway. Early evidence supports telepractice can improve patient access to services, enhance outcomes, and optimize health service efficiency; however, further systematic research is needed into these models, particularly relating to large-scale implementation and costs/economic analyses.

Examining user perceptions of SwallowIT: A pilot study of a new telepractice application for delivering intensive swallowing therapy to head and neck cancer patients.

Consumer feedback and end-user perceptions provide important information regarding the clinical acceptability of new telepractice systems. This pilot investigation aimed to evaluate end-user perceptions of a new asynchronous telepractice application, ' SwallowIT', designed to support patients to remotely complete intensive swallowing therapy during curative chemoradiotherapy (CRT) treatment for head and neck cancer (HNC). Insights were sought from 15 patients with oropharyngeal cancer who used SwallowIT to complete supported home swallowing therapy. Perceptions were evaluated via structured questionnaires, completed following initial orientation to SwallowIT and on completion of CRT. Semi-structured phone interviews were conducted ≥3 months post-treatment. The majority of patients reported positive initial perceptions towards SwallowIT for comfort (87%), confidence (87%), motivation (73%) and support (87%). No statistically significant change in perceptions was observed from baseline to end of CRT ( p > 0.05). Thematic analysis of interviews revealed four main themes: the ease of use of SwallowIT, motivating factors, circumstances which made therapy difficult, and personal preferences for service-delivery models. These preliminary findings demonstrate that SwallowIT was well-perceived by the current group of HNC consumers and suggest that SwallowIT may be well-accepted as an alternate service-delivery model for delivering intensive swallowing therapy during CRT.

Adherence to a Prophylactic Swallowing Therapy Program During (Chemo) Radiotherapy: Impact of Service-Delivery Model and Patient Factors.

Intensive, prophylactic swallowing therapy programs have been developed to improve dysphagia outcomes for patients with head/neck cancer (HNC) receiving (chemo)radiotherapy ([C]RT). Across studies, variable therapy adherence rates have been reported. Preliminary research suggests that service-delivery mode and demographic factors may influence adherence. This study examined patient adherence to a prophylactic swallowing therapy protocol across three service-delivery models: (1) clinician-directed face-to-face therapy, (2) technology-assisted therapy using the telepractice application, SwallowIT and (3) independent patient-directed therapy. The secondary aim explored the impact of patient factors on adherence. Patients with oropharyngeal HNC receiving definitive (C)RT were randomised to receive the Pharyngocise exercise protocol via clinician-directed (n = 26), patient-directed (n = 27) or SwallowIT-assisted (n = 26) models. Adherence was calculated as the percentage of prescribed exercise completed. Multiple patient factors were recorded at baseline. Adherence across the 6 weeks in all groups was low (27%), and declined from week 4 of (C)RT. The clinician-directed model yielded significantly (p = 0.014) better adherence than patient-directed therapy in weeks 1-3. There was also a trend for higher adherence in the SwallowIT group compared to patient-directed in weeks 1-3 (p = 0.064). Multivariable linear modelling identified active smoking at baseline (p < 0.001) and concomitant chemotherapy (p = 0.040) as significant negative predictors of adherence, with baseline reduced motivation trending towards significance. Although (C)RT-related toxicities will impact adherence, adopting service-delivery models with greater structure/support and providing extra assistance to patients with known risk factors may help optimise therapy adherence to prophylactic therapy programs. Telepractice may provide an alternate model to support adherence where service constraints limit intensive clinician-directed therapy.

"ScreenIT": Computerized screening of swallowing, nutrition and distress in head and neck cancer patients during (chemo)radiotherapy.

BACKGROUND: In light of growing service demands, the use of computerized screening processes have been proposed to optimize patient triage and enhance the efficiency and synergy of multidisciplinary care practices. This study evaluated the accuracy of a novel system, ScreenIT, to detect swallowing, nutrition and distress status in HNC patients receiving (chemo)radiotherapy ([C]RT), and facilitate appropriate referrals for MDT management. MATERIALS AND METHODS: Patient-reported data obtained from ScreenIT was compared to blinded face-to-face assessment by speech pathology/dietetic clinicians across five domains: side-effects, swallowing/oral intake, nutrition, distress, and need for supportive care services. Agreement was analysed using percent exact and close agreement (PEA/PCA) and kappa statistics. RESULTS: Clinically acceptable agreement (PEA/PCA 80% or higher) was achieved for the majority of domains. In areas of discordance, ScreenIT demonstrated a higher sensitivity to patient-perceived concerns, particularly regarding distress. Management pathways generated by ScreenIT initiated clinically appropriate referrals for high and medium-risk patients for swallowing/nutrition and distress. CONCLUSION: Findings suggest that ScreenIT may provide an effective and efficient means of monitoring swallowing, nutrition and distress status during (C)RT, and facilitate clinically appropriate prioritization of MDT supportive care intervention.

Computer Literacy and Health Locus of Control as Determinants for Readiness and Acceptability of Telepractice in a Head and Neck Cancer Population.

Understanding end-user populations is required in designing telepractice applications. This study explored computer literacy and health locus of control in head/neck cancer (HNC) patients to inform suitability for telerehabilitation. Sixty individuals with oropharygneal cancer were recruited. Computer literacy was examined using a 10-question survey. The Multidimensional Health Locus of Control Scale Form C (MHLC-C) examined perceptions of health "control". Participants were mostly middle-aged males, from high socioeconomic backgrounds. Only 10% were non-computer users. Of the computers users, 91% reported daily use, 66% used multiple devices and over 75% rated themselves as "confident" users. More than half were open to using technology for health-related activities. High internal scores (MHLC-C) signified a belief that own behaviour influenced health status. HNC patients have high computer literacy and an internal health locus of control, both are positive factors to support telepractice models of care. This may include asynchronous models requiring heightened capacity for self-management.

Evaluation of a weekly speech pathology/dietetic service model for providing supportive care intervention to head and neck cancer patients and their carers during (chemo)radiotherapy.

PURPOSE: Dysphagia is a common and debilitating side effect for head and neck cancer (HNC) patients undergoing radiotherapy (RT) with or without chemotherapy ([C]RT) and is associated with nutritional and emotional comorbidities. Emotional sequelae and distress are also known to affect carers of HNC patients. A weekly, joint speech pathology/dietetic (SP/DN) service-delivery model has been employed to manage swallowing/nutritional and associated emotional issues during (C)RT. This study aimed to conduct a service evaluation of the weekly SP/DN clinical model. METHODS: Cross-sectional sampling of core service metrics and perceptions of key stakeholders (70 HNC patients, 30 carers, and 10 clinicians) were collated from the Metro South Radiation Oncology Service in Brisbane, Australia. Data from each source was examined separately and then triangulated. RESULTS: An average of 28 patients (SD = 5.54) attended SP/DN appointments per week, with 58% reporting swallowing and/or nutritional issues. Distress was reported by 27% of patients and 30% of carers. Clinicians felt able to adequately identify and manage swallowing and nutrition 90% of the time but only 10% of the time for distress. Seventy-six percent of scheduled SP/DN sessions were perceived as necessary by either patients, clinicians or both. CONCLUSIONS: Findings demonstrated a third of patients and their carers had a high level of distress during HNC [C]RT, supporting need for the provision of a weekly SP/DN service in a select cohort. However, the routine weekly SP/DN assessment model for all patients undergoing HNC treatment demonstrates the potential for over-servicing. Alternative service-delivery models warrant further evaluation.

Can human mannequin-based simulation provide a feasible and clinically acceptable method for training tracheostomy management skills for speech-language pathologists?

PURPOSE: Workplace training for tracheostomy management is currently recognized to be inconsistent and insufficient. A novel approach, using technology-enhanced simulation, may provide a solution to training tracheostomy management skills by providing a consistent, time-efficient, and risk-free learning environment. The current research evaluated clinicians' tracheostomy skills acquisition after training in a simulated learning environment and explored changes in clinicians' confidence and perceptions after the experience. METHOD: Forty-two clinicians with no or low levels of tracheostomy skill attended one of six, 1-day simulation courses. The training involved both part-task skill learning and immersive simulated scenarios. To evaluate clinicians' acquisition of manual skills, performance of core tasks during the scenarios was assessed by independent observers. Questionnaires were used to examine perceived outcomes, benefits, and perceptions of the learning environment at pre-, post-, and 4 months post-training. RESULTS: Only 1 clinician failed to successfully execute all core practical tasks. Clinicians' confidence increased significantly ( p < .05) from pre- to post-workshop and was maintained to 4 months post-workshop across most parameters. All clinicians reported positive perceptions regarding their learning outcomes and learning in a simulated environment. CONCLUSION: These findings validate the use of simulation as a clinical training medium and support its future use in tracheostomy competency-training pathways.

UK survey of clinical consistency in tracheostomy management.

BACKGROUND: Many speech and language therapists (SLTs) work with patients who have a tracheostomy. There is limited information about their working practices and the extent to which recent publications and research have influenced the speech and language therapy management of the tracheostomized patient. AIMS: This study reviews the current patterns of clinical practice for SLTs in the management of adult tracheostomized patients in the UK. METHODS & PROCEDURES: An online questionnaire was completed by 106 SLTs with prior experience in tracheostomy management. The information from this was explored to determine patterns of practice across various areas of speech and language therapy tracheostomy management including clinical roles and responsibilities, management of communication disorders, and assessment and management of dysphagia and decannulation. These clinical patterns were then examined with respect to the current literature, emerging patterns in evidence-based practice and national practice guidelines. OUTCOMES & RESULTS: The results indicate a moderate to high level of clinical consistency in the majority of areas evaluated across the scope of tracheostomy management in speech and language therapy. Consistency in practice areas such as increased utilization of instrumental assessments and conservative use of the Modified Evans Blue Dye Test indicate clinical application in line with current research. Limited clinical consensus or inconsistencies in evidence-based services were identified in aspects of practice that are supported by conflicting or emerging research evidence. Such areas include involvement in cuff deflation regimes, adoption of specific decannulation procedures and participation in multidisciplinary team management. CONCLUSIONS & IMPLICATIONS: SLTs in the UK provide a moderate to high level of consistent practice in tracheostomy management. This study identifies areas of tracheostomy management that require further research in order to establish clinical practice guidelines and to address discrepancies between research evidence and clinical implementation.

Physiological changes to the swallowing mechanism following (chemo)radiotherapy for head and neck cancer: a systematic review.

Emerging research suggests that preventative swallowing rehabilitation, undertaken before or during (chemo)radiotherapy ([C]RT), can significantly improve early swallowing outcomes for head and neck cancer (HNC) patients. However, these treatment protocols are highly variable. Determining specific physiological swallowing parameters that are most likely to be impacted post-(C)RT would assist in refining clear targets for preventative rehabilitation. Therefore, this systematic review (1) examined the frequency and prevalence of physiological swallowing deficits observed post-(C)RT for HNC, and (2) determined the patterns of prevalence of these key physiological deficits over time post-treatment. Online databases were searched for relevant papers published between January 1998 and March 2013. A total of 153 papers were identified and appraised for methodological quality and suitability based on exclusionary criteria. Ultimately, 19 publications met the study's inclusion criteria. Collation of reported prevalence of physiological swallowing deficits revealed reduced laryngeal excursion, base-of-tongue (BOT) dysfunction, reduced pharyngeal contraction, and impaired epiglottic movement as most frequently reported. BOT dysfunction and impaired epiglottic movement showed a collective prevalence of over 75 % in the majority of patient cohorts, whilst reduced laryngeal elevation and pharyngeal contraction had a prevalence of over 50 %. Subanalysis suggested a trend that the prevalence of these key deficits is dynamic although persistent over time. These findings can be used by clinicians to inform preventative intervention and support the use of specific, evidence-based therapy tasks explicitly selected to target the highly prevalent deficits post-(C)RT for HNC.
