Mitigation of Respirable Aerosol Particles from Speech and Language Therapy Exercises

ABSTRACT: This data repository entry contains text files providing the data supporting the figures presented in: Mitigation of Respirable Aerosol Particles from Speech and Language Therapy Exercises Published in: Journal of Voice Abstract: Introduction: Phonation and speech are known sources of respirable aerosol in humans. Voice assessment and treatment manipulate all the subsystems of voice production, and previous work has demonstrated such activities can generate >10 times more aerosol than conversational speech and 30 times more aerosol than breathing. Aspects of voice therapy may therefore be considered aerosol generating procedures and pose a greater risk of potential airborne pathogen (e.g., SARS-CoV-2) transmission than typical speech. Effective mitigation measures may be required to ensure safe service delivery for therapist and patient. Objective: To assess the effectiveness of mitigation measures in reducing detectable respirable aerosol produced by voice assessment/therapy. Methods: We recruited 15 healthy participants (8 cis-males, 7 cis-females), 9 of whom were voice-specialist speech-language pathologists. Optical Particle Sizers (OPS) (Model 3330, TSI) were used to measure the number concentration of respirable aerosol particles (0.3 µm – 10 µm) generated during a selection of voice assessment/therapy tasks, both with and without mitigation measures in place. Measurements were performed in a laminar flow operating theatre, with near-zero background aerosol concentration, allowing us to quantify the number concentration of respiratory aerosol particles produced. Mitigation measures included the wearing of Type IIR fluid resistant surgical masks, wrapping the same masks around the end of straws, and the use of heat and moisture exchange microbiological filters (HMEFs) for a water resistance therapy (WRT) task. Results: All unmitigated therapy tasks produced more aerosol than unmasked breathing or speaking. Mitigation strategies reduced detectable aerosol from all tasks to a level significantly below, or no different to, that of unmasked breathing. Pooled filtration efficiencies determined that Type IIR surgical masks reduced detectable aerosol by 90%. Surgical masks wrapped around straws reduced detectable aerosol by 96%. HMEF filters were 100% effective in mitigating the aerosol from WRT, the exercise that generated more aerosol than any other task in the unmitigated condition. Conclusions: Voice therapy and assessment causes the release of significant quantities of respirable aerosol. However, simple mitigation strategies can reduce emitted aerosol concentrations to levels comparable to unmasked breathing.

Project description:BackgroundAphasia is an acquired language impairment following brain damage that affects some or all language modalities: expression and understanding of speech, reading, and writing. Approximately one third of people who have a stroke experience aphasia.ObjectivesTo assess the effects of speech and language therapy (SLT) for aphasia following stroke.Search methodsWe searched the Cochrane Stroke Group Trials Register (last searched 9 September 2015), CENTRAL (2015, Issue 5) and other Cochrane Library Databases (CDSR, DARE, HTA, to 22 September 2015), MEDLINE (1946 to September 2015), EMBASE (1980 to September 2015), CINAHL (1982 to September 2015), AMED (1985 to September 2015), LLBA (1973 to September 2015), and SpeechBITE (2008 to September 2015). We also searched major trials registers for ongoing trials including ClinicalTrials.gov (to 21 September 2015), the Stroke Trials Registry (to 21 September 2015), Current Controlled Trials (to 22 September 2015), and WHO ICTRP (to 22 September 2015). In an effort to identify further published, unpublished, and ongoing trials we also handsearched the International Journal of Language and Communication Disorders (1969 to 2005) and reference lists of relevant articles, and we contacted academic institutions and other researchers. There were no language restrictions.Selection criteriaRandomised controlled trials (RCTs) comparing SLT (a formal intervention that aims to improve language and communication abilities, activity and participation) versus no SLT; social support or stimulation (an intervention that provides social support and communication stimulation but does not include targeted therapeutic interventions); or another SLT intervention (differing in duration, intensity, frequency, intervention methodology or theoretical approach).Data collection and analysisWe independently extracted the data and assessed the quality of included trials. We sought missing data from investigators.Main resultsWe included 57 RCTs (74 randomised comparisons) involving 3002 participants in this review (some appearing in more than one comparison). Twenty-seven randomised comparisons (1620 participants) assessed SLT versus no SLT; SLT resulted in clinically and statistically significant benefits to patients' functional communication (standardised mean difference (SMD) 0.28, 95% confidence interval (CI) 0.06 to 0.49, P = 0.01), reading, writing, and expressive language, but (based on smaller numbers) benefits were not evident at follow-up. Nine randomised comparisons (447 participants) assessed SLT with social support and stimulation; meta-analyses found no evidence of a difference in functional communication, but more participants withdrew from social support interventions than SLT. Thirty-eight randomised comparisons (1242 participants) assessed two approaches to SLT. Functional communication was significantly better in people with aphasia that received therapy at a high intensity, high dose, or over a long duration compared to those that received therapy at a lower intensity, lower dose, or over a shorter period of time. The benefits of a high intensity or a high dose of SLT were confounded by a significantly higher dropout rate in these intervention groups. Generally, trials randomised small numbers of participants across a range of characteristics (age, time since stroke, and severity profiles), interventions, and outcomes.Authors' conclusionsOur review provides evidence of the effectiveness of SLT for people with aphasia following stroke in terms of improved functional communication, reading, writing, and expressive language compared with no therapy. There is some indication that therapy at high intensity, high dose or over a longer period may be beneficial. HIgh-intensity and high dose interventions may not be acceptable to all.

Project description:BACKGROUND:Few studies have analyzed gains in using computers in speech and language therapy interventions for children with speech and/or language disorders when compared to a control group, but virtual tutors and computer-based visual feedback have been gaining interest in the literature. Previous systematic reviews mainly focused on development technological details of computer-based speech training systems or the potential of integrating mobile technology into education and rehabilitation, but recent systematic reviews have also evaluated the efficacy of computer-based speech and language therapy for children and how digital technology can support different activities, at school or elsewhere. OBJECTIVE:This study aimed to analyze a continuous communication and joint team approach to develop solutions focused on the real needs of end users, which digitally emulate reliable and validated physical intervention materials for children with speech sound disorders (SSD). METHODS:The Table to Tablet (T2T) software was developed using a design-based research methodology, which included four phases: activities development; ethnographic pretesting with a sample from the target population; software development; and beta-testing. The technology used to develop the software, the method used to ensure satisfaction and replay ability of the intervention materials, and results from the ethnographic and beta-testing phases are presented. RESULTS:Nineteen activities were developed during the first phase, which were then tested, with 7 service users, using a physical prototype. The beta-test approach included extensive testing and reformulation, supported by direct, nonparticipant observation and data collection using a questionnaire designed for children. Feedback was used to improve the software and interaction with users. CONCLUSIONS:The use of T2T-based intervention programmes by speech and language therapists (SLTs) will allow these professionals to make a better and more effective communication intervention, based on proven methodologies, that coexists in a structured physical and a digital version. These versions provide a full, 6-week intervention program, with minimal effort in preparing the session by the SLTs while delivering a very consistent intervention, with high replay value. A continuous communication and joint team approach was beneficial to the project and to the development of a solution focused on the real needs of SLTs and children with SSD. All problems were approached as a team with different skills and expertise, which minimized errors (eg, the developer making choices that would save him from spending time doing something that would not be used) and time spent. To add to this, the importance of integrating the end users as testers and collecting their opinions and actions per session allowed the production of better-targeted activities.

Project description:Introduction: The UK's response to the COVID-19 pandemic presented multiple challenges to healthcare services including the suspension of non-urgent care. The impact on neurorehabilitation professions, including speech and language therapy (SLT), has been substantial. Objectives: To review the changes to SLT services triggered by the COVID-19 pandemic with respect to referral rates, service delivery and outcomes, as well as examining the contribution of SLTs to the neurorehabilitation of COVID-19 patients. Methods: Two surveys were distributed to Royal College of Speech and Language Therapists (RCSLT) members exploring experiences of service provision at 6 weeks and 22 weeks after the pandemic was declared in the UK. Responses to closed-ended questions, including questions regarding referral numbers were analyzed descriptively and compared at the two time-points. A database comprising routine clinical data from SLT services across the UK was used to compare information on patients receiving services prior to and during the pandemic. Data on COVID-19 patients was extracted, and findings are provided descriptively. Results: Referrals to SLT services during the acute COVID-19 period in the UK were substantially less than in the same period in 2019. A number of service changes were common including adopting more flexible approaches to provision (such as tele-therapy) and being unable to provide services to some patients. Database analysis suggests fewer patients have accessed SLT since the pandemic began, including a reduction in neurorehabilitation patients. For those who received SLT, the outcomes did not change. SLTs supported a range of needs of COVID-19 patients. Treatment outcomes for COVID-19 patients with dysphagia were positive. Discussion: The pandemic has affected neurorehabilitation and SLT services broadly: referral patterns are different, usual care has been disrupted and interventions have been modified affecting the impact on patient outcomes both positively and negatively. Some patients with COVID-19 require and benefit from SLT intervention.

Project description:IntroductionThe coronavirus disease 2019 (COVID-19) led to the worldwide closure of dental practices or reduction of dental services. By the end of April 2020, governments and professional organisations were publishing recommendations or guidance for the reopening/restructuring of dental services. The aim of this study was to assess how dental aerosol-generating procedures (AGPs) were defined in international dental guidelines, what mitigation processes were advised, and whether they were linked to COVID-19 epidemiology.MethodsElectronic searches of a broad range of databases, along with grey literature searches, without language restriction were conducted up to 13 July 2020. Recommendations for the use of face masks and fallow times with patients without COVID-19 were assessed against the deaths per 1 million population in the included countries and country income level using Pearson Chi-squared statistics.ResultsSixty-three guidance documents were included. Most (98%) indicated that AGPs can be performed with patients without COVID-19 with caveats, including advice to restrict AGPs where possible, with 21% only recommending AGPs for dental emergencies. Face masks were recommended by most documents (94%), with 91% also specifying the use of goggles or face shields. Fallow periods for patients without COVID-19 were mentioned in 48% of documents, ranging from 2 to 180 minutes. There were no significant differences in recommendations for face masks or fallow time in patients without COVID-19 by country death rate (P = .463 and P = .901) or World Bank status (P = .504 and P = .835). Most documents recommended procedural or environmental mitigations such as preprocedural mouthwash (82%) and general ventilation (52%). Few documents provided underpinning evidence for their recommendations.ConclusionsWhile the amount of high-quality direct evidence related to dentistry and COVID-19 remains limited, it is important to be explicit about the considered judgements for recommendations as well as generate new evidence to face this challenge.

Project description:ObjectiveThis study aimed to assess the cost-effectiveness of combined scalp acupuncture therapy with speech and language therapy for patients with Broca's aphasia after stroke.DesignA within-trial cost-effectiveness analysis.SettingsCommunity health centres.SubjectsA total of 203 participants with Broca's aphasia after stroke who had been randomly assigned to receive scalp acupuncture with speech and language therapy (intervention) or speech and language therapy alone (control).InterventionBoth groups underwent speech and language therapy (30 min per day, 5 days a week, for 4 weeks), while the intervention group simultaneously received scalp acupuncture.Primary outcomesAll outcomes were collected at baseline, and after the 4-week intervention and 12-week follow-up. Cost-effectiveness measures included the Chinese Rehabilitation Research Center Standard Aphasia Examination (CRRCAE) and Boston Diagnostic Aphasia Examination (BDAE). Cost-utility was evaluated using quality-adjusted life-years (QALYs). Incremental cost-effectiveness ratios were expressed, and sensitivity analysis was conducted.ResultsThe total cost to deliver the intervention was €4001.72, whereas it was €4323.57 for the control group. The incremental cost-effectiveness ratios showed that the intervention was cost-effective (€495.1 per BDAE grade gained; €1.8 per CRRCAE score gained; €4597.1 per QALYs gained) relative to the control over the 12 weeks. The intervention had a 56.4% probability of being cost-effective at the ¥50 696 (€6905.87) Gross Domestic Product (GDP) per capita threshold. Sensitivity analyses confirmed the robustness of the results.ConclusionsCompared with speech and language therapy alone, the addition of scalp acupuncture was cost-effective in Chinese communities. As the costs of acupuncture services in China are likely to differ from other countries, these results should be carefully interpreted and remain to be confirmed in other populations.Trial registration numberChiCTR-TRC-13003703.
