Pre- and post-operative voice therapy (PaPOV): Development of an intervention for patients with benign vocal fold lesions.

BACKGROUND: Pre- and post-operative voice therapy may improve voice and quality-of-life outcomes for patients undergoing phonosurgery to remove benign vocal fold lesions (BVFLs). However, what constitutes voice therapy in this population is poorly described, resulting in a poor evidence base, lack of clinical guidelines and unwarranted variation in management. In order to develop the evidence base, a robust, iterative process of intervention development work should precede feasibility testing and effectiveness studies. METHODS & PROCEDURES: Guidance for developing complex interventions, drawing on evidence, theory and modelling, was used to inform the development of a pre- and post-operative voice therapy intervention entitled 'PaPOV'. Data from four sources of evidence were synthesized using a published triangulation protocol. Data from a systematic review, national survey of current practice, expert interview study, and patient and public involvement conversations were used to populate a triangulation matrix, outlining components of a PaPOV. Data were coded to reflect areas of agreement, dissonance and silence with each component of the intervention. Based on this evidence, an assessment of convergence for each intervention component could be made. OUTCOMES & RESULTS: In total, 61 components of the PaPOV intervention were explored. Of these, 27 were categorized as having stability of consensus according to a priori criteria. A total of 34 failed to meet the criteria. This was more frequently due to silence (27) rather than dissonance (seven) in the data. By evidencing areas of agreement and stability of consensus across data sources, the validity of individual findings has been enhanced. Furthermore, the study has exposed specific areas of the intervention that lack consensus and require exploration through further intervention development studies. CONCLUSIONS & IMPLICATIONS: This systematic triangulation process has contributed to the development of a PaPOV intervention for patients with BVFLs. Exploration of specific components relating to the intervention will allow outstanding questions to be answered in preparation for feasibility testing. WHAT THIS PAPER ADDS: What is already known on the subject BVFLs cause dysphonia by preventing vocal fold closure, impacting on vibratory characteristics and increasing compensatory muscle tension. Management for these patients is variable with them being offered phonosurgery, voice therapy, pharmacological management or a combined approach. Pre- and post-operative voice therapy may improve both voice and quality-of-life outcomes. This patient group has unique complexities when considering voice therapy, including surgical preparation, wound healing and epithelial mobilization. What this paper adds to existing knowledge This study uses a robust triangulation process to synthesize current evidence and patient experiences in order to inform the development of a PaPOV. It outlines some of the key components and considerations when delivering pre- and post-operative voice therapy to adults with BVFLs. Furthermore, it serves as a methodological example for intervention development in complex interventions, highlighting key guidance and recommended processes for developing and evaluating complex interventions. What are the potential or actual clinical implications of this work? The 61 components discussed as potential 'ingredients' for a PaPOV enable clinicians to reflect on key considerations when planning and delivering voice therapy to adults with BVFLs. This study highlights the pitfalls both clinically and in research of failing to describe interventions adequately and the benefits of using accurate, specific and agreed terminology in clinical practice, such as that outlined in the Rehabilitation Treatment Specification System (TRSS).

Factors that influence development of speech pathology skills required for videofluoroscopic swallowing studies.

BACKGROUND: Perceptual, cognitive and previous clinical experience may influence a novice Videofluoroscopic Swallowing Study (VFSS) analyst's trajectory towards competency. Understanding these factors may allow trainees to be better prepared for VFSS training and may allow training to be developed to accommodate differences between trainees. AIMS: This study explored a range of factors previously suggested in the literature as influencing the development of novice analysts' VFSS skills. We hypothesised that knowledge of swallow anatomy and physiology, visual perceptual skills, self-efficacy and interest, and prior clinical exposure would all influence VFSS novice analysts' skill development. METHODS & PROCEDURES: Participants were undergraduate speech pathology students recruited from an Australian university, who had completed the required theoretical units in dysphagia. Data assessing the factors of interest were collected-the participants identified anatomical structures on a still radiographic image, completed a physiology questionnaire, completed subsections of the Developmental Test of Visual Processing-Adults, self-reported the number of dysphagia cases they managed on placement, and self-rated their confidence and interest. Data for 64 participants relating to the factors of interest were compared with their ability to accurately identify swallowing impairments following 15 h of VFSS analytical training, using correlation and regression analysis. OUTCOMES & RESULTS: Success in VFSS analytical training was best predicted by clinical exposure to dysphagia cases and the ability to identify anatomical landmarks on still radiographic images. CONCLUSIONS & IMPLICATIONS: Novice analysts vary in the acquisition of beginner-level VFSS analytical skill. Our findings suggest that speech pathologists who are new to VFSS may benefit from clinical exposure to dysphagia cases, sound foundational knowledge of anatomy relevant to swallowing and the ability to see the anatomical landmarks on still radiographic images. Further research is required to equip VFSS trainers and trainees for training, to understand differences between learners during skill development. WHAT THIS PAPER ADDS: What is already known on the subject The existing literature suggests that no vice Video fluoroscopic Swallowing Study (VFSS) analysts training may be influenced by their personal characteristics and experience. What this study adds This study found that student clinicians, clinical exposure to dysphagia cases and their ability to identify anatomical landmarks relevant to swallowing on still radiographic images prior to training best predicted their ability to identify swallowing impairments after training. What are the clinical implications of this work? Given the expense of training health professionals, further research is required into the factors that successfully prepare clinicians for VFSS training, including clinical exposure, foundational knowledge of anatomy relevant to swallowing and the ability to identify the anatomical landmarks on still radiographic images.

Interventions and strategies aimed at clinical academic pathway development for nurses in the United Kingdom: A systematised review of the literature.

AIMS AND OBJECTIVES: To review interventions and strategies designed to progress UK clinical academic career pathways in nursing and identify barriers and facilitators to aid wider implementation. BACKGROUND: For over a decade, the UK political agenda has promoted the entry of nurses into clinical academic roles. Partnerships between the National Health Service and academia are known to increase nursing recruitment, retention and quality of care. However, there remains a lack of nurses working in these partnership roles. DESIGN: A systematised review was conducted. An electronic database search was carried out in PubMed, CINAHL, the British Nursing Database and PsychInfo for articles published between September 2006 to June 2020. A narrative approach to data synthesis was used, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. RESULTS: Ten papers were included in the review. The authors reported a range of programmes, pathways and toolkits. Pathway outcome measures included numbers of nurses recruited onto clinical academic programmes, clinical academic programmes completed, nursing research outputs, impact on clinical practice and impact on nursing recruitment. Barriers and facilitators to pathway development included funding, clinical and research time constraints, infrastructure, strong and strategic clinical academic leadership and effective partnership working. The quality of the included studies was mixed; more high-quality, evidence-based programmes need to be developed and rigorously evaluated. CONCLUSIONS: The findings can inform nursing clinical academic research pathway development internationally, by identifying key drivers for success. Sustained and cohesive implementation of clinical academic research pathways is lacking across the UK. RELEVANCE TO CLINICAL PRACTICE: Strong, strategic leadership is required to enable progression of clinical academic nursing research pathway opportunities. Clinical nursing practitioners need to collaborate with external partners to enable development of clinical academic pathways within the nursing profession; this can lead to improvements in patient care and high-quality clinical outcomes.

COVID-19 and ENT SLT services, workforce and research in the UK: A discussion paper.

BACKGROUND: The COVID-19 pandemic and the UK government's subsequent coronavirus action plan have fundamentally impacted on every aspect of healthcare. One area that is severely affected is ear, nose and throat (ENT)/laryngology where speech and language therapists (SLTs) engage in a diverse range of practice with patients with a range of conditions, including voice disorders, airway problems, and head and neck cancers (HNCs). A large majority of these patients are in high-risk categories, and many specialized clinical practices are vulnerable. In addition, workforce and research issues are challenged in both the immediate context and the future. AIMS: To discuss the threats and opportunities from the COVID-19 pandemic for SLTs in ENT/laryngology with specific reference to clinical practice, workforce and research leadership. METHODS & PROCEDURES: The relevant sections of the World Health Organisation's (WHO) health systems building blocks framework (2007) were used to structure the study. Expert agreement was determined by an iterative process of multiple-group discussions, the use of all recent relevant policy documentation, and other literature and shared documentation/writing. The final paper was verified and agreed by all authors. MAIN CONTRIBUTION: The main threats to ENT/laryngology SLT clinical services include increased patient complexity related to COVID-19 voice and airway problems, delayed HNC diagnosis, reduced access to instrumental procedures and inequitable care provision. The main clinical opportunities include the potential for new modes of service delivery and collaborations, and harnessing SLT expertise in non-instrumental assessment. There are several workforce issues, including redeployment (and impact on current services), training implications and psychological impact on staff. Workforce opportunities exist for service innovation and potential extended ENT/SLT practice roles. Research is threatened by a reduction in immediate funding calls and high competition. Current research is affected by very limited access to participants and the ability to conduct face-to-face and instrumental assessments. However, research opportunities may result in greater collaboration, and changes in service delivery necessitate robust investigation and evaluation. A new national set of research priorities is likely to emerge. CONCLUSIONS & IMPLICATIONS: The immediate impact of the pandemic has resulted in major disruption to all aspects of clinical delivery, workforce and research for ENT/laryngology SLT. It is unclear when any of these areas will resume operations and whether permanent changes to clinical practice, professional remits and research priorities will follow. However, significant opportunity exists in the post-COVID era to re-evaluate current practice, embrace opportunities and evaluate new ways of working. What this paper adds What is already known on the subject ENT/laryngology SLTs manage patients with a range of conditions, including voice disorders, airway problems and HNCs. The diverse scope of clinical practice involves highly specialized assessment and treatment practices in patients in high-risk categories. A large majority of active research projects in this field are patient focused and involve instrumental assessment. The COVID-19 pandemic has created both opportunities and threats for ENT SLT clinical services, workforce and research. What this paper adds to existing knowledge This study provides a discussion of the threats and opportunities from the COVID-19 pandemic for ENT/laryngology SLT with specific reference to clinical practice, workforce and research leadership. What are the potential or actual clinical implications of this work? The COVID-19 pandemic has resulted in major disruption to all aspects of clinical delivery, workforce and research for ENT/laryngology SLT. Changes to clinical practice, professional remits and research priorities are of indeterminant duration at this time, and some components could be permanent. Significant clinical practice, workforce and research opportunities may exist in the post-COVID era.

Behavioural interventions to treat drooling in children with neurodisability: a systematic review.

AIM: To review the evidence for behavioural interventions to reduce drooling in children with neurodisability. METHOD: A detailed search in eight databases sought studies that: (1) included participants aged 0 to 18 years with neurodisability and drooling; (2) provided behavioural interventions targeting drooling or a drooling-related behaviour; and (3) used experimental designs. Two reviewers extracted data from full-text papers independently. Results were tabulated for comparison. The Risk of Bias assessment in N-of-1 Trials scale for single case experimental designs (SCEDs) and the Cochrane risk of bias assessment tool for randomized controlled trials (RCTs) were applied. RESULTS: Of an initial yield of 763, seven SCEDs and one RCT were included. Behavioural interventions included the use of reinforcement, prompting, self-management, instruction, extinction, overcorrection, and fading. Each assessed body functions or structures' outcomes (drooling frequency and severity); three included activity outcomes (mouth drying, head control, eye contact, and vocalizations) and none assessed participation or quality of life. While each study reported positive effects of intervention, risk of bias was high. INTERPRETATION: Low-level evidence suggests behavioural interventions may be useful for treatment of drooling in children with neurodisability. Well-designed intervention studies are urgently needed to determine effectiveness. WHAT THIS PAPER ADDS: Behavioural interventions used to treat drooling included reinforcement, prompting, self-management, extinction, overcorrection, instruction, and fading. Interventions targeted body structures and function-level outcomes and activity-level outcomes. Low-level evidence supports the use of behavioural intervention to treat drooling.

Communication changes with laryngectomy and impact on quality of life: a review.

PURPOSE: Patients with throat cancer at later stages often undergo total laryngectomy, a procedure that removes the larynx (voice box) and directly impacts the patient's ability to produce natural voice and communication. This narrative review aimed to explore how changes to communication following laryngectomy may impact quality of life (QoL) for patients. METHODS: Literature searches were conducted using CINAHL, MEDLINE and PsychInfo databases for studies published between 2007 and 2018. The search terms (and derivatives) of laryngectomy AND communication AND quality of life were used. A synthesis and appraisal of the studies was conducted. RESULTS: Twelve studies met the inclusion criteria and were included in this review. The two main themes identified relating to changes in communication and impact on QoL were changes in communication competency (immediate changes and communication option used) and adaptation to change (e.g. self-related factors and relationships with others). Regardless of the type of communication option used, participants in all studies reported negative changes in their communication competency and QoL post-laryngectomy. Voice-related factors and aesthetics of the communication option used were noted to influence self-ratings of QoL for the participants, rather than how well others understood them. Participants using tracheoesophageal speech (TES) consistently showed the highest self-reported QoL across the majority of studies. A model incorporating the findings from this review has been proposed which outlines how changes in communication post-laryngectomy may lead to an impact on QoL. Here, the factors of changes in communication competency, self-perception and social engagement impact each other and are also influenced by adaptation to change. CONCLUSION: This review has highlighted the complex nature of changes faced by patients following laryngectomy in relation to communication and QoL. The model linking communication changes to QoL may become a useful tool for researchers and clinicians in supporting the management of patients post-laryngectomy.

Vocal nodules management.

Vocal fold nodules present the voice clinic team with a number of clinical dilemmas which are not as simple as previously thought. The definition, aetiology, prevalence and diagnosis are all poorly understood. Furthermore, treatment evidence for both behavioural and surgical approaches is weak. This paper reviews the published evidence pertaining to all of these aspects. Specific areas of uncertainty that remain include poorly defined nomenclature, the natural history of paediatric vocal nodules, the establishment of criteria to measure successful treatment, optimal configuration of speech therapy regimens and the rationale for surgical intervention. The authors suggest the development of evidence-based guidelines for UK practice.

Head and neck cancer patients' perceptions of swallowing following chemoradiotherapy.

PURPOSE: The study aims to describe patients' experiences of swallowing difficulties following (chemo)radiotherapy for head and neck cancer and to explore any changes over time. METHODS: A purposive sample of patients with swallowing difficulties was selected at a range of time points, from 3 to 18 months following treatment. Ethnographic observations of 12 patients were conducted in their own homes, over a mealtime situation. Nine new patients were interviewed about changes to their eating and drinking from pre- to post-treatment. Thematic analysis was used to code and analyse the data. RESULTS: Patients' reports of swallowing function were divided into four time zones: pre-treatment, during radiotherapy, early (0-3 months) and late (6-18 months) time points following treatment. The majority reported minimal problems at diagnosis, but marked impairment during and after radiotherapy, without a return to pre-treatment functioning. The focus was on severe physical side effects and changes to food preparation during radiotherapy and in the early phase of recovery. By 6 months, side effects began to subside, but swallowing was still difficult, leading to major changes to family life, socialisation and lifestyle. CONCLUSIONS: Swallowing problems after (chemo)radiotherapy are multi-faceted and highly individualised and restrict lives in the long term. Swallowing ability may improve in time, but does not appear to return to pre-treatment function. Further work is required to find ways of being able to best support patients living with this long-term condition.

"Trust people you've never worked with" - A social network visualization of teamwork, cohesion, social support, and mental health in NHS Covid personnel.

Background: The unprecedented rapid re-deployment of healthcare workers from different care pathways into newly created and fluid COVID-19 teams provides a unique opportunity to examine the interaction of many of the established non-technical factors for successful delivery of clinical care and teamwork in healthcare settings. This research paper therefore aims to address these gaps by qualitatively exploring the impact of COVID work throughout the pandemic on permanent and deployed personnel's experiences, their ability to effectively work together, and the effect of social dynamics (e.g., cohesion, social support) on teamwork and mental health. Methods: Seventy-five interviews were conducted across the UK between March and December 2021 during wave 2 and 3 of COVID-19 with 75 healthcare workers who were either permanent staff on Intensive Care/High Dependency Units used as COVID wards, had been rapidly deployed to such a ward, or had managed such wards. Work Life Balance was measured using the WLB Scale. Interview transcripts were qualitatively coded and thematic codes were compared using network graph modeling. Results: Using thematic network analysis, four overarching thematic clusters were found, (1) teamwork, (2) organizational support and management, (3) cohesion and social support, and (4) psychological strain. The study has three main findings. First, the importance of social factors for teamwork and mental health, whereby team identity may influence perceptions of preparedness, collaboration and communication, and impact on the collective appraisal of stressful events and work stressors. Secondly, it demonstrates the positive and negative impact of professional roles and skills on the development of teamwork and team identity. Lastly the study identifies the more pronounced negative impact of COVID work on deployed personnel's workload, mental health, and career intentions, exacerbated by reduced levels of social support during, and after, their deployment. Conclusion: The thematic network analysis was able to highlight that many of the traditional factors associated with the successful delivery of patient care were impeded by pandemic constraints, markedly influencing personnel's ability to work together and cope with pandemic work stressors. In this environment teamwork, delivery of care and staff well-being appear to depend on relational and organizational context, social group membership, and psycho-social skills related to managing team identity. While results hold lessons for personnel selection, training, co-location, and organizational support during and after a pandemic, further research is needed into the differential impact of pandemic deployment on HCWs mental health and teamwork.

Developing novice analysts' videofluoroscopic swallowing study skills in speech-language pathology: A randomised control trial comparing blended and online training approaches.

PURPOSE: This research investigates the relative effectiveness of independent online and blended learning approaches for novice analysts' development of videofluoroscopic swallowing study (VFSS) analytical skills. The secondary aims were to explore the impact of training on decision-making and to describe learners' perspectives of training outcomes. METHOD: Undergraduate speech-language pathology students (n = 74) who had completed the dysphagia academic curriculum in an undergraduate speech-language pathology program were recruited for a randomised control trial. The ability to identify swallowing impairments in adults was compared pre- and post-training across three conditions: independent online (n = 23), peer-supported (n = 23), and expert-facilitated training (n = 28). The training comprised online VFSS training and practice with a commercially available digital video disc (DVD). RESULT: The three training approaches were equal in improving novice analysts' identification of impairments on VFSS. Participants' analysis improved pre- to post-training (p = <.001), with no statistical difference amongst training conditions (p = .280). However, the expert facilitation condition resulted in better decision-making skill for novice analysts, as well as higher levels of confidence and greater engagement in the learning. CONCLUSION: Well-designed independent online methods are appropriate to prepare novice analysts for VFSS analytical training. Expert facilitation and peer-supported environments may have benefits for more advanced skill development and engagement, and should be investigated in future studies.

Pre- and post-operative voice therapy for benign vocal fold lesions: protocol for a non-randomised, multicentre feasibility trial with embedded process evaluation.

BACKGROUND: Management of benign vocal fold lesions (BVFLs) is variable with individuals receiving surgery, voice therapy, or a combination of these approaches. Some evidence suggests that the best outcomes may be achieved when patients are offered pre- and post-operative voice therapy in addition to phonosurgery, but what constitutes pre- and post-operative voice therapy is poorly described. The pre- and post-operative voice therapy (PAPOV) intervention has been developed and described according to the TIDieR checklist and Rehabilitation Treatment Specification System (RTSS) for voice. The PAPOV intervention is delivered by specialist speech and language therapists trained in the intervention and comprises 7 essential and 4 additional components, delivered in voice therapy sessions with patients who are having surgery on their vocal folds for removal of BVFLs. STUDY DESIGN: Non-randomised, multicentre feasibility trial with embedded process evaluation. METHOD: Forty patients from two sites who are due to undergo phonosurgery will be recruited to receive the PAPOV intervention. Measures of feasibility, including recruitment, retention, and adherence, will be assessed. The feasibility of gathering clinical and cost effectiveness data will be measured pre-treatment, then at 3 and 6 months post-operatively. An embedded process evaluation will be undertaken to explain feasibility findings. DISCUSSION: This study will assess the feasibility of delivering a described voice therapy intervention protocol to patients who are undergoing surgery for removal of BVFLs. Findings will be used to inform the development and implementation of a subsequent effectiveness trial, should this be feasible. TRIAL REGISTRATION: This trial has been prospectively registered on ISRCTN (date 4th January 2023), registration number 17438192, and can be viewed here: https://www.isrctn.com/ISRCTN17438192 .

Pre and Post-operative Voice Therapy Intervention for Benign Vocal Fold Lesions: A Systematic Review.

Benign vocal fold lesions cause dysphonia by preventing vocal fold closure, causing irregular vibration and increasing compensatory muscle tension. Voice therapy delivered in addition to phonosurgery may improve voice and quality of life outcomes but the evidence base is lacking and what constitutes voice therapy for this population is not defined. The purpose of this systematic review is to critically evaluate the evidence for pre and post-operative voice therapy to inform the development of an evidence based intervention. STUDY DESIGN: Systematic Review. METHODS: Electronic databases were searched using key terms including dysphonia, phonosurgery, voice therapy and outcomes. Eligible articles were extracted and reviewed by the authors for risk of bias and for information regarding the content, timing and intensity of any pre and post-operative voice therapy intervention. RESULTS: Of the 432 articles identified, 35 met the inclusion criteria and were included in the review. 5 were RCTs, 2 were individual cohort studies, 1 was a case control study and 26 were case series. There was considerable heterogeneity in participant characteristics. Information was frequently lacking regarding the content timing and intensity of the reported voice therapy intervention, and where present, interventions were highly variable. CONCLUSION: Reporting in relevant literature is limited in all aspects of content, timing and intensity of intervention. Further intervention development work is required to develop a robust voice therapy treatment intervention for this population, before effectiveness work can commence.

Pre- and Postoperative Voice Therapy for Benign Vocal Fold Lesions: An International Electronic Delphi Consensus Study.

INTRODUCTION: Voice therapy management of benign vocal fold lesions (BVFLs) is variable and there are currently no clinical guidelines. Poor descriptions of voice therapy interventions lead to unwarranted variation in treatment. Triangulation of the current evidence identifies a number of potential best practice elements, but also a number of outstanding questions to be explored. The aim of this study was to refine and gain global consensus on "best practice" for a pre- and postoperative voice therapy intervention for adults with BVFLs. METHODS: An international sample of expert voice therapists (n = 42) were recruited to take part in this three-round electronic modified Delphi study. Participants were presented with statements concerning a pre- and postoperative voice therapy intervention. Statements were developed from previous research and based on the TIDieR checklist (eg, why, when, what, how?) Participants rated the extent to which they agreed or disagreed with a statement and gave comments to support their response. Consensus was defined as >75% of participants agreeing or strongly agreeing with a given statement. If consensus was not reached, participant comments were used to generate new statements and were rated in the next round. Stability of consensus between rounds was assessed. RESULTS: The 42 international experts achieved consensus on 33 statements relating to components of a best practice pre- and postoperative voice therapy intervention for patients with BVFLs. Consensus on statements ranged from 81% to 100%. These statements were explicitly mapped to the TIDieR checklist to ensure that all aspects of the intervention were considered and the questions of "why, what, how, when and individual tailoring" were addressed. CONCLUSIONS: This study has significantly enhanced our understanding of what should be in a best practice pre- and postoperative voice therapy intervention. It is important to now test these findings for acceptability and feasibility, prior to considering effectiveness research.

Pre- and Postoperative Voice Therapy for Benign Vocal Fold Lesions: Factors Influencing a Complex Intervention.

OBJECTIVES: (1) To describe factors influencing the content, timing, and intensity of pre- and postoperative voice therapy for patients undergoing phonosurgery for benign vocal fold lesions. (2) To understand experts' rationale for decisions made. (3) To critically analyze factors influencing intervention in relation to the wider literature in order to contribute to the development of a complex intervention. DESIGN: Qualitative interview study. SETTING: Multidisciplinary voice clinics in England. PARTICIPANTS: Ten expert voice therapists with a mean of 22 years experience. MAIN OUTCOME MEASURES: Participants were asked to describe factors influencing their current practice and views on optimum treatment for patients undergoing phonosurgery for benign vocal fold lesions. Data were analyzed using the Framework Method of thematic analysis. RESULTS: Factors influencing intervention related to four key themes. Pathophysiological, Patient, Therapist, and Service factors influenced the content, timing, and duration of the voice therapy provided. Consensus on core elements included delivering indirect and direct therapy preoperatively to manage underlying causative factors and address patient expectations. Postoperative intervention focused on indirect therapy to facilitate wound healing and direct therapy to improve vibratory characteristics of the vocal fold. Elements of therapy were highly individualized within participants according to the four themes above, but similarity between participants on broad parameters of intervention was high. CONCLUSIONS: Expert voice therapists use direct and indirect methods pre- and postoperatively to treat patients with benign vocal fold lesions. Optimizing wound healing and mobilization of the epithelium postoperatively are concerns for expert voice therapists which distinguish postoperative patients from other dysphonic patients. This study provides an insight into the factors influencing clinician's intervention provision which can contribute to the development of an optimal pre- and postoperative voice therapy intervention. Further research to refine and test the effectiveness of an intervention is now required.

Pitch Discrimination Testing in Patients with a Voice Disorder.

Auditory perception plays an important role in voice control. Pitch discrimination (PD) is a key index of auditory perception and is influenced by a variety of factors. Little is known about the potential effects of voice disorders on PD and whether PD testing can differentiate people with and without a voice disorder. We thus evaluated PD in a voice-disordered group (n = 71) and a non-voice-disordered control group (n = 80). The voice disorders included muscle tension dysphonia and neurological voice disorders and all participants underwent PD testing as part of a comprehensive voice assessment. Percentage of accurate responses and PD threshold were compared across groups. The PD percentage accuracy was significantly lower in the voice-disordered group than the control group, irrespective of musical background. Participants with voice disorders also required a larger PD threshold to correctly discriminate pitch differences. The mean PD threshold significantly discriminated the voice-disordered groups from the control group. These results have implications for the voice control and pathogenesis of voice disorders. They support the inclusion of PD testing during comprehensive voice assessment and throughout the treatment process for patients with voice disorders.

Understanding teamwork in rapidly deployed interprofessional teams in intensive and acute care: A systematic review of reviews.

The rapid increase of acute and intensive care capacities in hospitals needed during the response to COVID-19 created an urgent demand for skilled healthcare staff across the globe. To upscale capacity, many hospitals chose to increase their teams in these departments with rapidly re-deployed inter-professional healthcare personnel, many of whom had no prior experience of working in a high-risk environment and were neither prepared nor trained for work on such wards. This systematic review of reviews examines the current evidence base for successful teamwork in rapidly deployed interprofessional teams in intensive and acute care settings, by assessing systematic reviews of empirical studies to inform future deployments and support of rapidly formed clinical teams. This study identified 18 systematic reviews for further analysis. Utilising an integrative narrative synthesis process supported by thematic coding and graphical network analysis, 13 themes were found to dominate the literature on teams and teamwork in inter-professional and inter-disciplinary teams. This approach was chosen to make the selection process more transparent and enable the thematic clusters in the reviewed papers to be presented visually and codifying four factors that structure the literature on inter-professional teams (i.e., team-internal procedures and dynamics, communicative processes, organisational and team extrinsic influences on teams, and lastly patient and staff outcomes). Practically, the findings suggest that managers and team leaders in fluid and ad-hoc inter-professional healthcare teams in an intensive care environment need to pay attention to reducing pre-existing occupational identities and power-dynamics by emphasizing skill mix, establishing combined workspaces and break areas, clarifying roles and responsibilities, facilitating formal information exchange and developing informal opportunities for communication. The results may guide the further analysis of factors that affect the performance of inter-professional teams in emergency and crisis deployment.

The Relationship Between Pitch Discrimination and Acoustic Voice Measures in a Cohort of Female Speakers.

BACKGROUND: Evidence across a range of musically trained, hearing disordered and voice disordered populations present conflicting results regarding the relationship between pitch discrimination (PD) and voice quality. PD characteristics of female speakers with and without a musical training background and no self-reported voice disorder, and the relationship between PD and voice quality in this particular population, have not been investigated. AIMS: To evaluate PD characteristics in a cohort of female participants without a self-reported voice disorder and the relationship between PD and acoustic voice measures. METHOD: One hundred fourteen female participants were studied, all of whom self-reported as being non-voice disordered. All completed the Newcastle Assessment of Pitch Discrimination which involved a two-tone PD task. Their voices were recorded producing standardized vocal tasks. Voice samples were acoustically analyzed for frequency-domain measures (fundamental frequency and its standard deviation, and harmonics-to-noise ratio) and spectral-domain measures (cepstral peak prominence and the Cepstral/Spectral Index of Dysphonia). Data were analyzed for the whole cohort and for musical and non-musical training backgrounds. RESULTS: In the whole cohort, there were no significant correlations between PD and acoustic voice measures. PD accuracy in musically trained speakers was better than in non-trained speakers and correlated with fundamental frequency standard deviation in prolonged vowel tasks. Vocalists demonstrated superior PD accuracy and fundamental frequency standard deviation in prolonged vowels compared to instrumentalists but did not show significant correlations between PD and acoustic measures. The Newcastle Assessment of Pitch Discrimination was a reliable tool, showing moderate-good prediction value in differentiating musical background. CONCLUSIONS: There was little evidence of a relationship between PD and acoustic measures of voice quality, regardless of musical training background and superior PD accuracy among the musically trained. These data do not support ideas concerning the co-development of perception and action among individuals identified as having voice quality measures within normal ranges. Numerous measures of voice quality, including measures sensitive to pitch, did not distinguish across musically and non-musically trained individuals, despite individual differences in pitch discrimination.

Training for videofluoroscopic swallowing analysis: A systematic review.

PURPOSE: To synthesise the available evidence relating to best practice in training videofluoroscopy and barium swallow analysts. METHOD: The review was conducted according to the PRISMA statement and registered in PROSPERO (CRD42017053744). Data were extracted from nine databases. Studies were included if they described training approaches for clinicians or students of any profession learning to interpret videofluoroscopic (VFSS) or barium swallow studies and were written in English. The methods were heterogeneous and a metanalysis was not possible; a narrative review is presented. RESULT: Sixteen studies were eligible, including those designed to evaluate the influence of training as well as those that described training as part of validating an assessment tool or method. The quality of the studies was assessed with the Hawker scale and assigned an NHMRC rating. While the evidence was low quality (NHMRC level IV), training consistently improved the accuracy and reliability of clinicians and students conducting VFSS. No studies reported the outcome of training for barium swallow analysis. There was significant variability in the dose, method, and setting of training. CONCLUSION: To elucidate best practice in VFSS analysis to ensure training is cost effective and results in accurate diagnosticians requires further research.

Evaluation of an intensive voice treatment to reduce anterior drooling in children with cerebral palsy: Protocol for a concurrent multiple-baseline, single case experimental design study.

Anterior drooling is common in children with cerebral palsy (CP) and poses significant risks to the child's health. Causes of drooling include oro-motor dysfunction, inefficient swallowing and reduced sensation in the orofacial musculature. Behavioural interventions are frequently recommended to reduce drooling; however, this is in the absence of high-quality research evidence. This paper describes a protocol for evaluating the effectiveness of the Lee Silverman Voice Treatment LOUD (LSVT LOUD®) in reducing drooling; and optimising speech and swallowing in a group of children with CP. A structured and systematic visual analysis supplemented with statistical analyses will be used to analyse the data. The risk of bias in n-of-1 trials (RoBiNT) Scale [1] guided the design and implementation of the study.

Lansoprazole for persistent throat symptoms in secondary care: the TOPPITS RCT.

BACKGROUND: Persistent throat symptoms are commonly attributed to 'laryngopharyngeal reflux'. Despite a limited evidence base, these symptoms are increasingly being treated in primary care with proton pump inhibitors. OBJECTIVE: To assess the value of proton pump inhibitor therapy in patients with persistent throat symptoms. DESIGN: This was a double-blind, placebo-controlled, randomised Phase III trial. SETTING: This was a multicentre UK trial in eight UK ear, nose and throat departments. PARTICIPANTS: A total of 346 participants aged ≥ 18 years with persistent throat symptoms and a Reflux Symptom Index score of ≥ 10, exclusive of the dyspepsia item, were recruited. INTERVENTION: Random allocation (1 : 1 ratio) to either 30 mg of lansoprazole twice daily or matched placebo for 16 weeks. MAIN OUTCOME MEASURE: Symptomatic response (i.e. total Reflux Symptom Index score after 16 weeks of therapy). RESULTS: A total of 1427 patients were screened and 346 were randomised. The mean age was 52 years (standard deviation 13.7 years, range 20-84 years); 150 (43%) participants were male and 196 (57%) were female; 184 (53%) participants had a mild Reflux Symptom Index minus the heartburn/dyspepsia item and 162 (47%) had a severe Reflux Symptom Index minus the heartburn/dyspepsia item. A total of 172 patients were randomised to lansoprazole and 174 were randomised to placebo. MAIN OUTCOMES: A total of 267 participants completed the primary end-point visit (lansoprazole, n = 127; placebo, n = 140), of whom 220 did so between 14 and 20 weeks post randomisation ('compliant' group); 102 received lansoprazole and 118 received placebo. The mean Reflux Symptom Index scores at baseline were similar [lansoprazole 22.0 (standard deviation 8.0), placebo 21.7 (standard deviation 7.1), overall 21.9 (standard deviation 7.5)]. The mean Reflux Symptom Index scores at 16 weeks reduced from baseline in both groups [overall 17.4 (standard deviation 9.9), lansoprazole 17.4 (standard deviation 9.9), placebo 15.6 (standard deviation 9.8)]. Lansoprazole participants had estimated Reflux Symptom Index scores at 16 weeks that were 1.9 points higher (worse) than those of placebo participants (95% confidence interval -0.3 to 4.2; padj = 0.096), adjusted for site and baseline severity. SECONDARY OUTCOMES: Ninety-five (43%) participants achieved a Reflux Symptom Index score in the normal range (< 12) at 16 weeks: 42 (41%) in the lansoprazole group and 53 (45%) in the placebo group. A total of 226 participants completed the end-of-trial follow-up visit (lansoprazole, n = 109; placebo, n = 117), of whom 181 were 'compliant'. The mean Reflux Symptom Index scores at 12 months reduced from baseline in both groups [lansoprazole 16.0 (standard deviation 10.8), placebo 13.6 (standard deviation 9.6), overall 14.7 (standard deviation 10.2)]. A total of 87 (48%) participants achieved a Reflux Symptom Index score in the normal range at 12 months: 33 (40%) in the lansoprazole group and 54 (55%) in the placebo group. Likewise, the Comprehensive Reflux Symptom Score and Laryngopharyngeal Reflux - Health Related Quality of Life total scores and subscales all showed very similar changes in the lansoprazole and placebo cohorts at both 16 weeks and 12 months. LIMITATIONS: Drop-out rate and compliance are issues in pragmatic clinical trials. The Trial Of Proton Pump Inhibitors in Throat Symptoms (TOPPITS) aimed to detect clinically relevant difference with 90% power. The 346 randomised participants reduced to 283 at the primary end point; 267 completed the primary outcome measure, 220 within the protocol time scale. Despite this, the powers to detect the clinically relevant difference in Reflux Symptom Index score at 16 weeks were 82% (compliant comparison) and 89% (pragmatic comparison). The lack of difference between lansoprazole and placebo is generalisable across NHS clinics. CONCLUSIONS: Participants on lansoprazole did not report significantly better outcomes than participants on placebo on any of the three patient-reported outcome tools (Reflux Symptom Index, Comprehensive Reflux Symptom Score and Laryngopharyngeal Reflux - Health Related Quality of Life). This multicentre, pragmatic, powered, definitive Phase III trial found no evidence of benefit for patients by treating persistent throat symptoms with lansoprazole.

BACKGROUND: One of the commonest reasons for patients attending hospital throat or voice clinics is persistent throat symptoms, which include a feeling of a lump in the throat, a cough or a hoarse voice. Over time, more of these patients are being treated with proton pump inhibitors to suppress stomach acid in the belief that stomach acid entering the throat causes the symptoms, but there is little evidence that these medications work. STUDY AIM: The aim of this study is to explore whether or not having a 16-week course of proton pump inhibitors has any impact on throat symptoms. We also tested the usefulness of three different questionnaires in measuring throat symptoms, explored side effects and whether or not patients adhere to treatment, and measured patients' quality of life. METHODS: Patients with persistent (lasting for more than 6 weeks) throat symptoms who agreed to participate were randomised to receive either the proton pump inhibitor lansoprazole or a placebo. Participants took lansoprazole or placebo for 16 weeks. Symptoms and quality of life were measured before patients were randomised and at 4 and 12 months after randomisation. RESULTS: The total number of participants was 346. The mean Reflux Symptom Index outcome score (higher scores meaning worse symptoms) was 22 before the 4-month course of capsules, 16 after 4 months and 15 after 12 months. Participant-reported throat symptoms and quality of life in all participants improved over the 12 months of the study. There was no difference in the symptom improvement experienced by proton pump inhibitor and placebo participants. CONCLUSIONS: This study shows that proton pump inhibitors do not benefit patients with persistent throat symptoms. Future research should focus on other available therapies.
