Microhardness of different thicknesses of bulk fill composites.

PURPOSE: To compare the microhardness values and bottom/top hardness ratios of different composites after being cured in 2 or 4 mm increments. METHODS: Two bulk fill composites, methacrylate-based and ormocer-based, and one conventional composite were tested. 36 cylindrical discs were prepared (n=12/composite, with six for 2 mm, and six for 4 mm thickness) by pressing each composite into a mold between two glass slides covered by Mylar strips. The top and bottom surfaces of each sample were evaluated using a Buehler hardness tester for Knoop microhardness, with a 50 g static load applied for 10 seconds at three different locations of the central part of each sample. The bottom/top hardness ratio was calculated for each sample. The Knoop microhardness data and bottom/top ratio percentages were analyzed using two-way repeated measures ANOVA and Holm-Sidak post hoc test, with significance at P< 0.05. RESULTS: The tested methacrylate-based bulk fill had the highest overall microhardness among the three tested composites. All three composite types showed a significant difference in microhardness between the top and bottom of the 4 mm discs. The bottom/top ratio percentages differed significantly for both tested bulk fill composites across different thicknesses. Both tested bulk fill materials had a bottom/top ratio of ≥ 80% at the deepest level of a 4 mm increment. CLINICAL SIGNIFICANCE: The type of material significantly affected both the bottom and top microhardness values under the experimental conditions used. While both tested bulk fill composites showed a decline in microhardness at the bottom of the 4 mm depth, they had clinically acceptable microhardness ratios at greater depths.

Comparative evaluation of subgingival scaling and polishing techniques on dental material surface roughness.

PURPOSE: To evaluate and compare the effects of different scaling and polishing techniques on the surface roughness of four different restorative materials. METHODS: 72 specimens were prepared, molded to a size of 8.0 by 2.0 mm, and cured according to the manufacturers' instructions. The specimens were stored at 37°C for 24 hours and then thermocycled for 5,000 cycles (from 55°C to 5°C) to simulate 6 months of clinical use. Surface roughness (Ra/average and Rz/max-overall heights) was calculated using a stylus profilometer by subtracting the simulated treatments of hand scaling, ultrasonic scaling, and air polishing from the baseline measurements. The difference in Ra and Rz data were compared independently for each measurement using a two-way ANOVA on Ranks and the Holm-Sidak test, with α< 0.05 used to determine significance. RESULTS: Irrespective of the scaling or polishing technique employed, flowable bulk fill demonstrated the lowest Ra and Rz values. Hand scaling exhibited the highest roughness and variability among the other techniques, regardless of the materials tested (P< 0.001). Air polishing with glycine resulted in the lowest roughness values across all tested materials, with the exception of the tested bioactive restorative material group. CLINICAL SIGNIFICANCE: Regarding surface roughness, air polishing with glycine may be an effective and safe intervention for periodontal maintenance of subgingival restorations compared to the other tested scaling methods.

Global citizenship and social justice among speech-language pathologists: A scoping review.

INTRODUCTION: This scoping review outlines the literature findings that relate to global citizenship and the interconnection between social justice among health professionals, specifically speech-language pathologists. The review aims to provide a synthesis of the relevant literature and thorough thematic identification of common themes. METHOD: Arksey and O'Malley's scoping review framework was used for the searching of critical databases, specifically CINAHL, Medline, the Cochrane Library and Google Scholar. Following the appraisal and synthesis process of the relevant literature, key themes were identified with particular reference to social justice among health professionals (especially speech-language pathologists). RESULTS: Four (4) key themes were identified, namely, (i) education and ongoing developmental support, (ii) ethical and moral obligations, (ii) cultural competency, and (iv) community engagement for intergroup empathy and helping. CONCLUSION: This review defines the parameters of a speech-language pathologists' practice as a global citizen interconnected with social justice and the accountabilities to enable impactful changes creating culturally sustaining practice.

Development and Pilot Testing of Telesimulation for Pediatric Feeding: A Feasibility Study.

Simulation enables learners to practice new skills in a supportive environment. Largely driven by the COVID-19 pandemic, simulation via telepractice, i.e., telesimulation, has emerged. Viable delivery of telesimulation requires consideration of the adaptations needed to conduct simulation via telepractice. The aim of this study was to design and pilot test the feasibility of using telesimulation to provide training in infant feeding management. An iterative process was used across four phases: (1) simulation design, (2) telesimulation adaptations, (3) user testing, feedback, and modifications, and (4) user testing of modified simulation, feedback, and final modifications. During Phases 1 and 2, team members worked together to design and test telepractice adaptations for a simulation experience. During Phases 3 and 4, the telesimulation was pilot tested with a group of speech pathologists, with feedback sought via open-ended survey questions and/or an optional focus group. Manifest content analysis was used to interpret user feedback. In Phase 2, several adaptations were explored to optimize telesimulation delivery and engagement, including Zoom® functions (e.g., 'spotlighting,' digital backgrounds) and supplementary video/auditory files. There were 11 participants across Phases 3 and 4. Specific feedback centered around simulation preparation and structure, session practicalities, supports for realism, Zoom® functions, group dynamics, participants' experiences, and future enhancements. An overall list of recommendations for telesimulation was generated. Telesimulation for feeding management was considered feasible and participant feedback was favorable. Further research is required to investigate if the learner outcomes of telesimulation are comparable to in-person simulation for infant feeding management.

The VOTIS, part 2: Using a video-reflexive assessment activity to foster dispositional learning in interprofessional education.

Effective interprofessional collaborative practice (IPCP) requires a new way of working characterized by distributed leadership skills, shared decision-making, and the adoption of uniprofessional and interprofessional identities. Health professional educators are tasked with preparing clinicians for IPCP through interprofessional education (IPE). Numerous IPE teaching interventions have been developed, ranging in length from hours to semesters, designed to introduce students to interprofessional ways of working - usually evaluated in terms of student satisfaction, perceptions of other disciplines and conceptual knowledge. However, working interprofessionally also requires integrating dispositional knowledge into one's emerging interprofessional habits and values. In this paper, we describe a learning activity, inspired by a new video-reflexive methodology, designed to foster dispositional learning of interprofessional skills using a video-based assessment tool: the Video Observation Tool for Interprofessional Skills (VOTIS). Based on focus group and interview data, we suggest the activity's usefulness in fostering conceptual, procedural and dispositional knowledge, as well as reflexive feedback literacy. Overall, our qualitative evaluation of the VOTIS suggests the merits of drawing on video-reflexive methodology and pedagogical theory to re-imagine IPE as a dynamic process, requiring the development of interprofessional skills that must be appropriated into students' emerging (inter)professional identities.

The VOTIS, part 1: development and pilot trial of a tool to assess students' interprofessional skill development using video-reflexive ethnography.

This paper explores the development and evaluation of the video Observation Tool for Interprofessional Skills (VOTIS). We describe the development of an authentic interprofessional assessment tool that incorporates video reflection and allows formative and summative assessment of individual learners' interprofessional skills within an authentic interprofessional context. We then investigate its validity and reliability. The VOTIS was developed using a modified Delphi technique. The tool was piloted with 61 students and 11 clinical educators who completed the VOTIS following team meetings where students interacted about their interprofessional clinical work. The following were calculated: internal consistency; students' proficiency levels; inter-rater reliability between students and clinical educators; and inter-rater reliability between clinical educators and an independent rater. Results indicate that the VOTIS has acceptable internal consistency and moderate reliability and has value in evaluating students' interprofessional skills. Study outcomes highlight the need for more explicit wording of tool content and instructions and further clinical educator training to increase the utility and reliability of the VOTIS as a learning and assessment tool.

A cost analysis of a 5-day simulation-based learning program for speech-language pathology student training.

Purpose: There is poor reporting of the cost of simulation and greater transparency is needed. The primary study aim was to conduct a financial analysis of the university/training institution costs associated with a 5-day simulation-based learning program for speech-language pathology students. The secondary aim was to consider the economic costs of the model.Method: Costs associated with the delivery of a 5-day simulation-based learning program for speech-language pathology students from six Australian universities were collected regarding: (a) pre-program training, (b) personnel, (c) room hire, (d) equipment, and (e) consumables. Both financial costs and economic costs (Australian dollar, at June 2017) were calculated per university site, and per student.Result: The simulation program was run 21 times involving 176 students. Average total financial cost per program ranged from $4717 to $11 425, with cost variation primarily attributed to local labour costs and various use of in-kind support. Average financial cost per student was $859 (range $683-$1087), however this was almost double ($1461 per student, range $857-$2019) in the economic cost calculation. Personnel was the largest contributing cost component accounting for 76.6% of financial costs. Personnel was also the highest contributing cost in the economic analysis, followed by room hire.Conclusion: This study provides clarity regarding financial and economic costing for a 5-day simulation-based learning program. These data can help universities consider potential up-front financial costs, and well as strategies for financial cost minimisation, when implementing simulation-based learning within the university context.

Do composite resin polishing systems damage enamel?

Finishing and polishing of composite resin restorations may cause damage to the bordering enamel. Although many studies have investigated the effect of polish on restorative materials, few have quantified the effect on bordering enamel. The objective of this study was to compare enamel loss surrounding composite restorations after finishing and polishing sequences. The null hypothesis was that there would be no difference in enamel loss between different finishing and polishing sequences. Class V preparations on the buccal and lingual surfaces of 15 extracted human molars were restored with a composite resin and assigned to 1 of 2 finishing and polishing sequences, so that each tooth underwent both sequences (n = 15 per sequence). In sequence 1, a tungsten carbide finishing bur and aluminum oxide polishing discs were used; in sequence 2, a diamond finishing bur, aluminum oxide-impregnated finishing cup, and diamond-impregnated polishing cup were used. Tooth surfaces were scanned with an optical scanner after preparation, finishing, initial polishing, and final polishing. The finishing and polishing scans were aligned to the preparation scan using Cumulus software. The depth of enamel surface loss was calculated and statistically analyzed (α = 0.05; paired t test). Most enamel loss (mean [SD]) resulted from the finishing step with the tungsten carbide bur (51.8 [21.3] µm) or diamond bur (43.3 [12.6] µm). Each polishing step increased mean enamel loss by only a few microns. There was no statistically significant difference between the 2 finishing and polishing sequences. The majority of enamel damage during finishing and polishing of composite resin restorations resulted from the finishing burs. Little enamel was removed by either of the tested composite resin polishing systems.

The perspectives of Australian speech pathologists in providing evidence-based practices to children with autism.

BACKGROUND: Bridging the research-practice gap in autism communication services is an identified priority for improving services. Limited research has investigated the views of practitioners regarding this research-practice gap. Investigation of the barriers experienced and facilitators used in clinical practice may assist to identify scalable and sustainable strategies to increase use of evidence-based practices (EBPs) in the delivery of communication services to children with autism. AIMS: To elucidate how Australian speech pathologists engage with external evidence and how communication outcomes are measured to demonstrate the effectiveness of service provision to children with autism. METHODS & PROCEDURES: A total of 15 Australian speech pathologists, with experience ranging from less than 1 to more than 16 years, participated in three focus groups. Data from focus groups were analysed using reflexive thematic analysis within an interpretive phenomenological paradigm. OUTCOMES & RESULTS: Seven themes were identified. Participants reported on the diversity of individuals with autism, their experiences of resource constraints, seeking collegial advice and accessing a diverse range of evidence sources, the role of clinical expertise in translating evidence to practice, the barriers experienced in outcome measurement and use of stakeholders to facilitate data collection to demonstrate outcomes. CONCLUSIONS & IMPLICATIONS: Individual practitioner skill and beliefs are facilitators to translating research to practice. Interventions to improve clinician use of EBP should address the skill and belief barriers, aiming to increase a clinician's EBP self-efficacy and increasing their expectation that investing in EBP activities will result in improved services for children with autism. Modelling and reflective practice are two strategies that may have an application as interventions to improve EBP use in clinical practice. WHAT THIS PAPER ADDS: What is already known on the subject Constrained resources, especially lack of time, is a barrier to routine uptake of best available evidence in clinical services for children with autism. What this paper adds to existing knowledge In this study, the perception that speech pathologists lacked time to engage in EBP activities was linked with the speech pathologist's research skill and their beliefs about the benefits of engaging in EBP. Speech Pathologists reported using a range of information sources, as "evidence" but also reported feeling uneasy when using evidence of disputable, or unknown quality. Accessibility and relevance to their individual client were highly prioritised in selecting evidence. Clinical expertise was an essential skill for research translation. What are the potential or actual clinical implications of this work? Interventions which target professional beliefs and research translation capability are requisite for motivating speech pathologists to improve their use of EBP. Modelling of EBP use, individual reflective practice and collegial active listening to facilitate reflective practice, might be useful strategies which target beliefs and capability of individual speech pathologists; thereby changing their EBP use.

Dual-cure dental composites: can light curing interfere with conversion?

Dual-cure composites used for dental restorations offer photo- and self-activation, promising unlimited curing depth. This study examined depth of cure with respect to light- and self-cure capabilities. Four dual-cure composites (BulkEZ; Activa; HyperFIL; Injectafil) were tested, with bulk fill (Tetric) and universal (TPH) light-cure composites as comparison. Composites were irradiated from one direction in molds. Additionally, dual-cure composites were left to self-cure without irradiation. Vickers hardness was measured up to 6 mm deep. Results were analyzed with two-way ANOVA and pairwise comparisons (α = 0.05). Hardness dropped significantly with depth in light- and dual-cured composites, except BulkEZ. Self-cured dual-cure composites achieved constant hardness throughout their depth. Only BulkEZ was unaffected by curing mode. Irradiation significantly decreased hardness in middle sections of Hyperfil and Injectafil compared with self-cured samples. Dual-cure composites cured substantially through 6 mm depths but curing behaviors differed. Whereas irradiation did not affect one dual-cure composite, in two other dual-cure composites low-density light levels interfered with the self-polymerization aspect.

Strength and stiffness of interim materials and interim fixed dental prostheses when tested at different loading rates.

STATEMENT OF PROBLEM: How the loading rate might affect the mechanical properties of interim materials and interim fixed dental prostheses is unclear. PURPOSE: The purpose of this in vitro study was to compare the material stiffness, material strength, and structural strength of interim 3-unit fixed dental prostheses fabricated from 3 interim materials when stressed at different loading rates. MATERIAL AND METHODS: Bar-shaped specimens and anatomically correct interim 3-unit fixed dental prostheses with a modified-ridge lap pontic were fabricated from polyethyl methacrylate resin (Trim) and 2 bis-acrylic composite resins (TempSmart; Integrity) (n=10). Flexural modulus and strength of the bar specimens, representing material stiffness and strength, were determined with a 4-point bend test in a universal testing machine. The structural strength of the prosthesis was assessed from the failure load from a vertical force applied on the occlusal surface of the pontic. Three loading rates, 0.5, 5, or 10 mm/min, were evaluated. Results were statistically analyzed with 2-way analysis of variance and multiple comparisons (α=.05). RESULTS: Loading rate and material significantly affected flexural modulus, flexural strength, and structural strength (P<.05). Increasing loading rate significantly increased the flexural modulus of all materials (P<.05), but the effect of loading rate on the flexural strength of bis-acrylic composite resins was mostly insignificant. Polyethyl methacrylate specimens did not fracture when loaded at 0.5 or 5 mm/min, and the interim fixed dental prostheses made from polyethyl methacrylate did not fracture at the 0.5 mm/min loading rate. Dual-polymerizing bis-acrylic composite resin had significantly higher flexural modulus and strengths than autopolymerizing bis-acrylic composite resin. CONCLUSIONS: Polyethyl methacrylate resin had the lowest stiffness among the interim materials tested and did not fracture but excessively deformed at the low loading rate. Dual-polymerizing bis-acrylic composite resin consistently had higher stiffness and material strength and provided higher structural strength than the autopolymerizing bis-acrylic composite resin. Loading rate significantly affected the mechanical properties of polyethyl methacrylate resin (P<.05), but the effect was indistinct for the bis-acrylic materials.

Student Perceptions of Simulation to Enhance Clinical Readiness for Assessment and Management of Adults With Voice Disorders.

BACKGROUND: Simulation is a safe, supported, and accessible learning method for students to gain skills and experience, especially in difficult to access range of practice areas such as voice. OBJECTIVE: The study aimed to explore change in students' perceptions of knowledge, confidence, anxiety, and clinical readiness for assessment and management of an adult with a voice disorder after participation in simulation-based learning activities. METHODS: Participants (N = 113) were students enrolled in a mandatory course dedicated to the voice and voice disorders. Students completed 32 hours of academic coursework which included lectures and tutorials and two 30-minute simulation-based learning activities with a standardized patient playing the role of an adult with a voice disorder. The impact of the simulation-based learning activities on student perceptions of their knowledge, confidence, anxiety, and clinical readiness for work within the area of voice were surveyed at three time points: (1) pre lectures, (2) post lectures but pre simulation, and (3) post simulation. Change across time was analyzed using repeated measures analysis of variance with post hoc Bonferroni adjustment. RESULTS: All students perceived significant (P ≤ 0.001) positive changes in knowledge and confidence across time points for all activities, except for writing an assessment report. Anxiety related to the management of a client with a voice disorder fluctuated significantly (P ≤ 0.001) throughout the program. Overall, the majority (>90%) of students agreed or strongly agreed that the simulation-based learning activities were useful and helped them to develop clinical skills, apply content taught in lectures, and gain confidence and interest in voice. CONCLUSION: This study supports incorporation of simulation-based learning as part of students' clinical preparation for the assessment and management of voice disorders.

Does a simulation-based learning programme assist with the development of speech-language pathology students' clinical skills in stuttering management?

BACKGROUND: Simulation-based learning can be used in university programmes to provide speech-language pathology students with essential clinical experiences. However, limited research has explored the use of simulation to support students' development of skills in clinical practice with people who stutter. AIMS: (1) To evaluate students' clinical skills in managing stuttering within a simulation-based learning programme; (2) to develop an assessment tool, the Standardised Patient Interview Rating Scale for Stuttering (SPIRS-Stuttering); and (3) to conduct a preliminary investigation of its validity in measuring students' performance. METHODS & PROCEDURES: Speech-language pathology students (n = 114) participated in a simulation-based stuttering programme in addition to academic coursework in fluency disorders. Students' clinical skills were assessed over two simulation sessions using the SPIRS-Stuttering tool, adapted from an earlier iteration of the SPIRS tool. Content validity, intra-rater reliability and internal consistency of the SPIRS-Stuttering tool were also explored. OUTCOMES & RESULTS: Students demonstrated a statistically significant improvement in stuttering clinical skills between sessions 1 and 4 of the simulation-based stuttering programme. Good content validity was achieved for the SPIRS-Stuttering tool with a low level of intra-rater reliability and variable internal consistency. CONCLUSIONS & IMPLICATIONS: This study identified that students' clinical skills in stuttering improved during participation in a simulation-based programme undertaken in conjunction with an academic course on fluency disorders. The results of this study support the inclusion of this learning modality in university programme curricula. Whilst the SPIRS-Stuttering tool enabled assessment of speech-language pathology students' clinical skills in stuttering management, further exploration of reliability is required. WHAT THIS PAPER ADDS: What is already known on this subject Within speech-language pathology, simulation-based learning is a teaching approach used in university clinical programme curricula. Simulation-based learning is used as an opportunity for students to gain specific clinical skills, particularly if clinical experiences are readily not available. Research in speech-language pathology has revealed that students value simulation because it provides a safe learning environment. What this study adds to existing knowledge There are fewer opportunities for students to gain clinical experience in the management of stuttering in adults. This study explored students' clinical skill development within a stuttering simulation-based learning programme. Additionally, it detailed the development and preliminary investigation of validity of the SPIRS-Stuttering, an assessment tool used in a simulation-based learning environment. What are the potential or actual clinical implications of this work? Students' clinical skills in the assessment and management of stuttering in adults, as measured by the SPIRS-Stuttering, improved during participation in the stuttering simulation-based learning programme. Further investigation of validity of the SPIRS-Stuttering tool is required to confidently measure students' performance. The stuttering simulation-based learning programme can be used to provide students with an opportunity to develop their clinical skills in stuttering, a practice area in speech-language pathology that is not always available to students.

Reflecting on culturally responsive goal achievement with indigenous clients using the Australian Therapy Outcome Measure for Indigenous Clients (ATOMIC).

INTRODUCTION: Appropriate evaluation of health services for First Australians demands culturally responsive goal setting tools that can be used by inter-professional teams. The Australian Therapy Outcome Measure for Indigenous Clients (ATOMIC) is a purpose-designed tool for measuring therapy outcomes for First Australians. The aim of this study was to establish the clinical utility of the ATOMIC by investigating its alignment with the practice perspectives of an inter-professional First Australian health service. METHODS: Using action research cycles, 12 occupational therapists and 8 speech pathologists applied two successive versions of the ATOMIC in practice. Focus group feedback after use of the first version (ATOMICv1) prompted adaptations to the tool (ATOMICv2). Therapists participated in four focus groups, two after using ATOMICv1 and two after using ATOMICv2. Focus group transcripts were analysed inductively using a qualitative description approach. RESULTS: Challenges in setting SMART goals early in therapy and defining specific measurement increments in ATOMICv1 led to therapists favouring skill-based goals that were easier to measure rather than broader daily life goals, thereby impacting on occupation- and client-centred practice. ATOMICv2 allowed goal setting at any point in therapy, evaluated goals using visual analogue scales, and gathered evidence for rating goal achievement throughout the therapy process. Therapists found the ATOMICv2 to be a culturally responsive tool that aligned with practice perspectives by foregrounding relationship building, facilitating clinical reasoning, documenting daily life changes, and providing integrated inter-professional care. CONCLUSION: The ATOMIC demonstrated good clinical utility in an inter-professional service for First Australian children. It aligned with a culturally responsive practice perspective and captured goal achievement in daily life contexts. Further research is needed to gain client perspectives across the lifespan and to investigate its application by other health professions.

The current practices of Australian speech-language pathologists in providing communication services to children with autism spectrum disorder.

PURPOSE: Evidence-Based Practice (EBP) is fundamental to speech-language pathology practice. Australian speech-language pathologists (SLPs) who treat communication disorders in children with autism spectrum disorder (ASD) face unique challenges in implementing EBP. Challenges may include selecting an intervention from a myriad of available interventions for use within a complex population. Identification of current practices of Australian SLPs in communication service provision to children with ASD will provide a baseline for use of EBP and may guide future efforts to engage in EBP. METHOD: A total of 109 Australian SLPs who provide communication services to children with ASD completed an online survey. Descriptive and inferential statistics were used to analyse service delivery and participant experiences of EBP. RESULT: The most common barrier to delivering EBP was inadequate resources. The most utilised strategy was discussing evidence with colleagues. Most participants reported using therapies which did not adhere to a standard protocol, such as eclectic approaches. The majority also reported use of outcome measures which they believe adequately represent functional communication changes for their client. CONCLUSION: Resource limitations may result in over-reliance on interventions lacking empirical support and over-reliance on subjective outcome measurement tools. Reflective practice and self-evaluation of communication services to children with ASD may support improved provision of EBP.

Speech-language pathology students' perceptions of simulation-based learning experiences in stuttering.

BACKGROUND: Research suggests that some speech-language pathologists are uncomfortable treating people who stutter. Accessing quality clinical education experiences in stuttering is difficult given the ongoing rise in students enrolled in speech-language pathology programmes and the limited number of stuttering-specific placements available. Simulation-based learning is a viable option for providing speech-language pathology students with practical experience in a safe learning environment. Whilst research has found that simulation-based learning experiences in stuttering assist in the development of students' clinical skills, students' perceptions of participating in stuttering simulation-based learning are yet to be explored. AIMS: To investigate speech-language pathology students' comfort, anxiety, knowledge and confidence in the management of stuttering at the commencement of an academic stuttering course and before and following participation in a stuttering simulation-based learning programme. METHODS & PROCEDURES: This study used a cross-sectional survey design. Participants were 105 undergraduate and graduate entry masters speech-language pathology students enrolled at an Australian university. Students engaged in a stuttering simulation-based learning programme embedded within an existing academic course on the management of stuttering. A purposefully developed survey was administered at three time points: pre-course (T1), pre-simulation (T2) and post-simulation (T3) in order to explore students' comfort and anxiety levels, and perceptions of their knowledge and confidence in stuttering management. Descriptive statistics were used to report the medians and range of students' responses. Changes across all time points and between each of the time points were determined using the Friedman test and the Wilcoxon signed rank test, respectively. OUTCOMES & RESULTS: Statistically significant differences (p < 0.001) were observed on all matched survey items (n = 96) across all time points. Between each time point, a significant difference in students' perceived knowledge levels was found with small to large effect sizes. However, there was no difference in students' perceived comfort and anxiety levels between the time points of pre-course and pre-simulation. Open-ended responses on the post-simulation survey revealed that students valued learning about stuttering within a simulation-based learning environment. CONCLUSIONS & IMPLICATIONS: Simulation-based learning experience in stuttering management was valued by students. When accompanied by theoretical content, participation in a stuttering simulation-based learning programme supported students to feel more comfortable and less anxious about working with people who stutter. This finding has implications for the development of clinical skills in the assessment and treatment of adults who stutter. WHAT THIS PAPER ADDS: What is already known on this subject Simulation is a teaching approach used within speech-language pathology to support the development of students' clinical skills. Simulation provides a safe learning environment for students, an opportunity for repeated practice and is valued by students. What this paper adds to existing knowledge This study explored students' perceptions of their comfort, anxiety, knowledge and confidence in working with people who stutter before and following participation in a simulation-based learning programme. It describes a stuttering simulation-based learning programme that can be embedded into speech-language pathology programme curricula. What are the potential or actual clinical implications of this work? The stuttering simulation-based learning programme detailed in this study can be applied and embedded in speech-language pathology curricula. It can be used to support the development of students' confidence in the assessment and management of stuttering.

Setting a prioritized agenda to drive speech-language therapy research in health.

BACKGROUND: Prioritized research agendas are viewed internationally as an important method for ensuring that health research meets actual areas of clinical need. There is growing evidence for speech-language therapy-prioritized research agendas, particularly in disorder-specific areas. However, there are few general research priority agendas to guide speech-language therapy research. AIMS: To collaboratively develop a prioritized research agenda for an Australian public health context with clinical speech-language therapists (SLTs), academic SLTs and consumers of speech-language therapy services. METHODS & PROCEDURES: An initial stimulus list of potential research areas for prioritization was collected from SLTs via an online survey. Two categories (service delivery and expanded scope of practice) were selected from this list for prioritization due to their relevance across multiple health services. The Nominal Group Technique (NGT) was used to develop a prioritized research agenda for each of the two categories. One NGT session was conducted with each of the three participant groups (clinical SLTs, academic SLTs, consumers) for each category (total NGT sessions = six). The prioritization data for each group within each category were summed to give a single, ranked prioritized research agenda for each category. OUTCOMES & RESULTS: Two prioritized research agendas were developed. Within each agenda, SLTs and consumers prioritized a need for more research in areas related to specific practice areas (e.g., Alternative and Augmentative Communication, Communication Partner Training), as well as broader professional issues (e.g., telehealth, working with culturally and linguistically diverse families). CONCLUSIONS & IMPLICATIONS: The current findings support the need for funding proposals and targeted projects that address these identified areas of need. WHAT THIS PAPER ADDS: What is already known on this subject Evidence-based practice is a critical component of SLT practice. There is often a disconnect between the research evidence generated and areas of clinical need, and in some areas a lack of evidence. Prioritized research agendas can help drive research in areas of clinical need. What this paper adds to existing knowledge A collaborative, prioritized SLT research agenda was developed using the NGT according to the views of clinical SLTs, academic SLTs and consumers of speech-language therapy services in a conglomerate of public health services. SLTs and consumers identified a need for further research in specific areas of SLT practice as well as broader emerging professional issues What are the potential or actual clinical implications of this work? Targeted research projects funded on a large scale are required to address these identified areas of need. Other health services around the world could replicate this prioritization process to drive research in areas of clinical need.

Simulation can replace part of speech-language pathology placement time: A randomised controlled trial.

PURPOSE: Simulation is increasingly used within speech-language pathology education. Research has primarily explored students' perceptions of learning in simulation. The aim of this study was to determine if speech-language pathology students achieved a statistically-equivalent level of competency when a mean of 20% of placement time was replaced with simulation compared to placements without a simulation component. METHOD: This non-inferiority randomised controlled trial involved students from six Australian universities. Students were randomised to either a simulation + traditional placement group attending 5 days of simulation prior to their traditional placement, or a traditional only placement group. Their end-placement clinical competency was assessed using Competency Assessment in Speech Pathology (COMPASS®). RESULT: Final data were available for 325 students: 150 students in traditional placements, 138 students in protocol-compliant simulation + traditional placements, and 37 students in non-protocol simulation + traditional placements. There were no statistically significant differences between groups (traditional vs protocol-compliant simulation + traditional Mann-Whitney-Wilcoxon z = 1.23, df = 286, p = 0.22; traditional vs intention-to-treat simulation + traditional Mann-Whitney-Wilcoxon z = 0.23, df = 323, p = 0.81). CONCLUSION: This research contributes to the evidence base which suggests that simulation can partially replace traditional placement time for speech-language pathology students without loss of competency, substantiating its value as an alternative placement model in speech-language pathology programmes.

Student perceptions of factors that influence clinical competency in voice.

PURPOSE: This study aimed to explore factors, perceived by students themselves, that help or hinder development of competency in voice. METHOD: Focus group interviews were conducted with a convenience sample of 14 speech pathology students (93% female, mean age 22 years). Interviews were transcribed verbatim and analysed using template analysis. RESULT: Students' perceptions of influencing factors were grouped into two major themes: (1) personal factors, and (2) educational factors. A key finding was that many participants perceived a student's own voice to be a major factor impacting their development and attainment of clinical competency in voice, and that mindsets towards the (un)changeability of students' own voices varied across participants. Students with a performance background were considered to be at an advantage in terms of performing vocal tasks and suitability to work with specific populations. Key facilitatory educational factors included access to and experience of demonstrations (face-to-face and video), additional training workshops, peer learning, and simulation. CONCLUSION: This study identified a number of personal and educational factors that students perceive to impact the development of competency in voice. Consideration of these holistic factors may assist speech-language pathology educators to deliver optimally effective voice-related curricula.
