Clinical outcomes associated with speech, language and swallowing difficulties post-stroke.

BACKGROUND:  There is a lack of prospective research in South Africa's speech therapy private sector, specifically, in the acute stroke population. There is a need to understand the quality of speech therapy services and outcomes post-stroke in the private sector. OBJECTIVES:  This prospective cohort study investigated associations between speech, language, and swallowing conditions (i.e. dysarthria, apraxia of speech, aphasia, dysphagia), and outcomes post-stroke (i.e. length of hospital stay [LOS], degree of physical disability according to the Modified Rankin Scale [mRS], functional level of oral intake according to the Functional Oral Intake Scale [FOIS], dehydration, weight loss, aspiration pneumonia, mortality). METHOD:  A prospective design was used to determine the incidence of speech, language, and swallowing conditions post-stroke. Convenience sampling was used to select participants (N = 68). Various statistical tests were used and the alpha level was set at Bonferroni correction p  0.01. RESULTS:  Co-occurring speech, language, and swallowing conditions frequently occurred post-stroke (88%). Participants who were referred to speech therapy later than 24 h post-admission (52.94%) stayed in hospital for a median of 3 days longer than those who were referred within 24 h (p = 0.042). Dysphagia was significantly associated with moderate to severe physical disability (p  0.01). Dysphagia with aspiration was significantly associated with poor functional level of oral intake, at admission and at discharge (p  0.01). At discharge, aspiration pneumonia was significantly associated with severe physical disability (p  0.01, r = 0.70). CONCLUSION:  In South Africa's private sector, co-occurring speech, language, and swallowing conditions commonly occurred post-stroke, and dysphagia was strongly associated with physical disability and poor functional level of oral intake. Length of hospital stay was increased by delayed speech therapy referrals.Contribution: This article contributes data on speech therapy services, communication and swallowing disorders post-stroke, and outcomes in South Africa's private sector.

Vuvuzelas at South African soccer matches: risks for spectators' hearing.

South African Premier Soccer League (PSL) matches are known worldwide as some of the noisiest recreational events. Therefore, the objectives of this study were to i) measure noise levels during different PSL matches; ii) measure changes in auditory function after attending PSL matches; and iii) determine the factors that increase the risk of overexposure to noise during PSL matches. The study used a descriptive quantitative analytical pre- and post-exposure design. Participants (n = 19, and n = 10) attended two PSL matches. Each participant's auditory function was assessed using distortion product oto-acoustic emissions (DPOAEs) before and after attending a PSL match. Peak and equivalent continuous noise levels as well as noise dose were measured during each match. Noise levels recorded during the poorly attended Match 1 were lesser than those of the well-attended Match 2. Participants attending Match 2 had statistically significant reduction in their DPOAE amplitudes after the match (P = 0.003) than those attending Match 1. Vuvuzela blowers and participants seated within 1 m from them were most at risk of harm to their hearing with significant reduction in DPOAE amplitudes post the match (P = 0.002 and P = 0.008, respectively). It was therefore concluded that noise levels at well-attended South African PSL matches pose a significant risk to spectators' auditory function as shown by reduced DPOAE amplitude post match attendance. Three risk factors for overexposure to noise during the match were identified: blowing the vuvuzela, close proximity to the individual blowing the vuvuzela as well as spectator turnout at the match.

Contextually appropriate school entry hearing screening protocol for low- and middle-income countries: A scoping review.

BACKGROUND: In low- and middle-income countries (LMICs), where universal newborn hearing screening programmes are often not available, school entry hearing screening programmes serve as a safeguard for early detection and intervention for hearing loss in school learners. OBJECTIVE: To determine a contextually appropriate school entry hearing screening protocol for LMICs. METHODS: A scoping review was utilised to comprehensively search for relevant publications in the following electronic databases: Africa-Wide Information, CINAHL, Health Source: Nursing/Academic Edition, Cochrane Library, Pubmed, Scopus, and Web of Science. Studies included those that investigated school-based hearing screening protocols or programmes for LMICs among learners aged five to twelve years. The review was conducted and reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist. RESULTS: The search yielded 1863 studies, and after removing duplicates and ineligible studies, 19 studies were selected for data extraction. Pure tone audiometry screening was the most frequently used age-appropriate hearing screening test in the reviewed studies (n = 17). Conducting pure tone audiometry screening using 1, 2, and 4 kHz frequency combination resulted in referral rates ranging from 3.2% to 21%. In studies that included 0.5 kHz to the screening frequencies, referral rates ranged from 5.8% to 56%. Screening at 25 dB HL intensity level yielded referral rates ranging from 3.2% to 10.3%. Immediate rescreening reduced overall referral rates for learners referred for audiological diagnostic testing by up to 57%. Ambient noise levels were controlled by conducting screening in quiet rooms (n = 14) and utilising screening equipment that allows for monitoring and reducing environmental noise (n = 3). CONCLUSION: An ideal school entry hearing screening protocol in LMIC contexts could potentially utilise pure tone audiometry screening at 1, 2, and 4 kHz, using 25 dB HL screening intensity level with an immediate rescreen for learners with a refer result. School entry hearing screening should be conducted in a quiet room, preferably using hearing screening equipment capable of monitoring ambient noise levels to reduce false positive referrals.

A retrospective review of speech-language therapy services provided to adult inpatients at a central-level hospital in Gauteng, South Africa.

BACKGROUND: The quadruple burden of disease (BoD) and multimorbidity reflected in South Africa's public health sector challenges speech-language therapists (SLTs) to optimise patient management in this context. For planning and delivery of appropriate services, it is important to understand the profile of speech-language therapy (SLT) patients and the public healthcare services provided by SLTs. OBJECTIVES: This study aimed to describe the prevalence of inpatient adult speech, language and swallowing disorders associated with various medical conditions and South Africa's BoD, in addition to the target areas and duration of SLT interventions provided at a central public hospital. METHOD: A retrospective review was conducted on records of 2549 adult inpatients who received SLT services between January 2014 and December 2015 at Chris Hani Baragwanath Academic Hospital. Data, including demographics, medical and SLT diagnoses, and treatment recommendations, were analysed using descriptive and inferential statistics. RESULTS: Non-communicable diseases (NCDs) were most prevalent (77.48%), with multimorbidity of BoD categories in 29.27% of patients. Cerebrovascular disease (CeVD) comprised 52.45% patients, with CeVD, traumatic brain injury, other neurological conditions, cancer and burns comprising 88.74% patients. More than a third of the patients with CeVD were 56 years (n = 486; 36.35%). Dysphagia (48.96%), aphasia (30.95%) and dysarthria (23.62%) were the most common, with 44.68% of patients having multiple SLT diagnoses. The number of SLT sessions significantly correlated with SLT comorbidity (rs = 0.4200; p = 0.0000), but not BoD comorbidity (rs = 0.0049; p = 0.8058). CONCLUSION: Speech-language therapy patients reflected a heavy NCD burden and multimorbidity. Provision of SLT services should take into consideration a profile of increased complexity of medical conditions and SLT diagnoses.

Paediatric dysphagia within the context of South Africa's quadruple burden of disease, seen at a tertiary level hospital.

Purpose: To inform service provision, this study explored feeding and swallowing difficulties in children within the context of South Africa's quadruple burden of disease (BOD) (i.e. conditions characterised as communicable, non-communicable, maternal and/or perinatal and trauma).Method: A retrospective chart review of 1432 paediatric inpatients (under 12 years of age) who met the inclusion criteria of presenting with dysphagia and being referred for speech-language pathology services was conducted.Result: Participants with diagnoses within the maternal and/or perinatal BOD category were noted most frequently (61.2%), followed by non-communicable (59.7%), communicable (43.4%) and trauma (4.2%). The majority of participants were under 1 year of age (82.2%) and 56.2% presented with comorbidities in multiple BOD categories. Mortality was 5.9%, with a higher rate (67.7%) in more complex cases. Mortality was associated with non-communicable BOD (p = 0.001), and maternal and/or perinatal BOD (p = 0.003). Pharyngeal phase swallowing difficulties were a significant risk for mortality (OR = 2.96; 95% CI: 1.01-8.65, p = 0.047).Conclusion: The majority of children with dysphagia presented with multiple comorbidities and were at high risk for mortality. Education and service delivery models should be designed to improve health outcomes and reduce mortality rates.

The lived experience of mothers of children with chronic feeding and/or swallowing difficulties.

The purpose of this phenomenologic study was to describe the lived experiences of seven mothers who were providing home-based care for their children with feeding and/or swallowing difficulties. Data were collected using semistructured interviews and were analysed as per Colaizzi's method of inductive reduction. Results suggest that the mothers' experiences can be understood as two continuing journeys that were not mutually exclusive. The first, "Deconstruction: A journey of loss and disempowerment," comprised three essences: (1) losing the mother dream, (2) everything changes: living life on the margins, and (3) disempowered: from mother to onlooker. The second journey was "Reconstruction: Getting through the brokenness" with the essences of (4) letting go of the dream and valuing the real, (5) self-empowered: becoming the enabler, (6) facilitating the journey, and (7) the continuing journey: negotiating balance. The phenomenon of being the mother of a child with chronic feeding and/or swallowing difficulties continued to be a transformative experience in which personal growth emerged along with chronic sorrow and periodic resurgence of struggle and loss. Implications call for healthcare professionals to incorporate maternal meanings and needs in providing appropriate family-focused intervention.

The Prevalence of Speech and Language Disorders in French-Speaking Preschool Children From Yaoundé (Cameroon).

Purpose: The purpose of this study was to determine the prevalence of speech and language disorders in French-speaking preschool-age children in Yaoundé, the capital city of Cameroon. Method: A total of 460 participants aged 3-5 years were recruited from the 7 communes of Yaoundé using a 2-stage cluster sampling method. Speech and language assessment was undertaken using a standardized speech and language test, the Evaluation du Langage Oral (Khomsi, 2001), which was purposefully renormed on the sample. A predetermined cutoff of 2 SDs below the normative mean was applied to identify articulation, expressive language, and receptive language disorders. Fluency and voice disorders were identified using clinical judgment by a speech-language pathologist. Results: Overall prevalence was calculated as follows: speech disorders, 14.7%; language disorders, 4.3%; and speech and language disorders, 17.1%. In terms of disorders, prevalence findings were as follows: articulation disorders, 3.6%; expressive language disorders, 1.3%; receptive language disorders, 3%; fluency disorders, 8.4%; and voice disorders, 3.6%. Conclusion: Prevalence figures are higher than those reported for other countries and emphasize the urgent need to develop speech and language services for the Cameroonian population.

Clinical educators' experiences of facilitating learning when speaking a different language from both the student and client.

BACKGROUND: Worldwide there is an increasing responsibility for clinical educators to help students from different language backgrounds to develop the necessary skills to provide health care services to a linguistically diverse client base. This study describes the experiences of clinical educators who facilitate learning in contexts where they are not familiar with the language spoken between students and their clients. A part of the qualitative component of a larger mixed methods study is the focus of this paper. Semi-structured interviews were conducted with eight participants recruited from all audiology university programmes in South Africa. Thematic analysis allowed for an in depth exploration of the research question. Member checking was used to enhance credibility. It is hoped that the findings will inform training programmes and in so doing, optimize the learning of diverse students who may better be able to provide appropriate services to the linguistically diverse population they serve. RESULTS: Participants experienced challenges with fair assessment of students and with ensuring appropriate client care when they were unable to speak the language shared between the client and the student. In the absence of formal guidelines, clinical educators developed unique coping strategies that they used on a case-by-case basis to assess students and ensure adequate client management when they experienced such language barriers while supervising. Coping strategies included engaging other students as interpreters, having students role-play parts of a session in English in advance and requesting real-time translations from the student during the session. They expressed concern about the fairness and efficacy of the coping strategies used. CONCLUSIONS: While clinical educators use unique strategies to assess students and to ensure suitable client care, dilemmas remain regarding the fairness of assessment and the ability to ensure the quality of client care.

The occurrence of auditory dysfunction in children with TB receiving ototoxic medication at a TB hospital in South Africa.

OBJECTIVES: to describe the auditory dysfunction of children with tuberculosis receiving ototoxic medication at a residential TB hospital in the Cape Town metropolitan area. METHODS: A descriptive survey research design was adopted. The auditory status of participants was evaluated by otoscopy, immittance, audiometry or OAE and AABR (depending on the age). STUDY SAMPLE: 29 in-patients (7 months to 16.6 years). RESULTS: Fifty five percent of participants presented with middle ear abnormalities (n=16) and 48% (n=12) had sensorineural or mixed hearing loss. The degree of hearing loss ranged from mild to profound in 16% of the ears. The conventional pure-tone average of .5, 1, & 2 kHz did not allow for the determination of the degree of hearing loss in the remaining 18% which had high frequency hearing loss. CONCLUSIONS: The high occurrence of hearing loss necessitates the implementation of monitoring program for children receiving ototoxic medication. Consideration should be given to using the average of hearing thresholds at 4, 6 and 8 kHz to determine the classification of degree of hearing loss in cases of ototoxicity.

New graduates' perceptions of preparedness to provide speech-language therapy services in general and dysphagia services in particular.

BACKGROUND: Upon graduation, newly qualified speech-language therapists are expected to provide services independently. This study describes new graduates' perceptions of their preparedness to provide services across the scope of the profession and explores associations between perceptions of dysphagia theory and clinical learning curricula with preparedness for adult and paediatric dysphagia service delivery. METHODS: New graduates of six South African universities were recruited to participate in a survey by completing an electronic questionnaire exploring their perceptions of the dysphagia curricula and their preparedness to practise across the scope of the profession of speech-language therapy. RESULTS: Eighty graduates participated in the study yielding a response rate of 63.49%. Participants perceived themselves to be well prepared in some areas (e.g. child language: 100%; articulation and phonology: 97.26%), but less prepared in other areas (e.g. adult dysphagia: 50.70%; paediatric dysarthria: 46.58%; paediatric dysphagia: 38.36%) and most unprepared to provide services requiring sign language (23.61%) and African languages (20.55%). There was a significant relationship between perceptions of adequate theory and clinical learning opportunities with assessment and management of dysphagia and perceptions of preparedness to provide dysphagia services. CONCLUSION: There is a need for review of existing curricula and consideration of developing a standard speech-language therapy curriculum across universities, particularly in service provision to a multilingual population, and in both the theory and clinical learning of the assessment and management of adult and paediatric dysphagia, to better equip graduates for practice.

"By the end of this course you should be able to...": towards constructive alignment in the SLP curriculum.

This paper describes the way in which constructive alignment is being implemented in the Speech-language Pathology (SLP) programme at a South African university. We focus on one of the courses, Human Communication Development, that comprises the four year programme of study. A first year, first semester course that is attended by both SLP and Audiology students, it aims to introduce fundamentals of the communication process and its development at a pre-clinical level. We aim to show how theoretical principles from higher education can be implemented at a micro level in a course of the SLP Programme. The principles of constructive alignment are introduced and exemplified through description of the revision of this course. All academic and clinical staff involved in the programme contributed to the development of the course. A template for curriculum revision is presented which allows for the explicit alignment of intended learning outcomes, teaching and learning activities and criterion referenced assessment. Staff participants recorded reflections on their own learning in personal reflection logs. Through this journaling process parallels are drawn between the' teachers'v oyage of discovery and that of the students.
