Background: Cape Town Minstrel Carnival is one of the oldest and most authentic indigenous New Year's customs in South Africa. Musicians who perform at this carnival are exposed to excessively loud music and therefore at a risk of acquiring noise-induced hearing loss (NIHL).

Objectives: This study aimed to determine patterns of exposure to loud music and prevalence of hearing loss amongst Cape Town Minstrel Carnival musicians.

Method: A descriptive, observational exploratory survey design was used and 43 participants (21 males and 22 females; mean age, 21 ± 9 years) took part in this study. Sound level measurements were conducted to assess musicians' sound exposure during rehearsals and performances. All participants underwent the following audiological test battery at least 2 h before music exposure: Case history, otoscopic examination, tympanometry, pure tone audiometry and distortion products otoacoustic emission (DPOAE).

Results: Average noise levels recorded were 86 dBA during rehearsals and 98.7 dBA at performances and average durations of exposure were 240 and 10 min at rehearsals and performances, respectively. One out of 43 (1/43) participants presented with sensorineural hearing loss. Audiometric results of the remaining participants were normal and did not show a pattern suggestive of NIHL. A high proportion of participants (21/43) reported experiencing tinnitus.

Conclusion: Despite being exposed to high levels of noise, there was a low prevalence of hearing loss amongst these musicians. However, a high proportion of them reported tinnitus, which could be an indication that they were at a high risk of NIHL from the music that they played.

Background: The absence of best practice guidelines on informational counselling, has caused lack of clarity regarding the information audiologists should provide to parents and caregivers following the diagnosis of a hearing loss. Research shows that informational counselling provided by audiologists is limited and often biased, with little evidence of how parents experience this service.

Objectives: To explore the nature and practice of informational counselling by audiologists.

Method: This study was descriptive in nature and adopted a survey design to obtain information on the current practices of informational counselling from the perspective of parents and primary caregivers. Ninety-seven face-to-face semi-structured interviews were conducted across KwaZulu-Natal province of South Africa. Descriptive statistics and thematic analysis using Nvivo software were conducted.

Results: The majority of the parents reported receiving some form of informational counselling. However, the information provided by audiologists was considered to be biased as it included a favoured communication option, school and rehabilitative technology. There was a lack of information related to aural rehabilitation and family-centred intervention. The provision of all communication options, school options and rehabilitative technology were identified as gaps that contribute to an unfavourable decision-making process.

Conclusion: There are inefficiencies experienced by families of deaf and hard of hearing children during informational counselling. However, this understanding, together with the identified gaps by parents, can help address the professional response to caring for families with deaf and hard of hearing children.

Background: Factors that influence various professionals to pursue postgraduate studies have been investigated. However, there is a dearth of evidence of factors that influence South African speech language pathologists (SLPs) and audiologists (As) to pursue their postgraduate studies.

Objective: Therefore, this study aimed to determine factors that influence the decision of South African SLPs and As to pursue postgraduate studies and potential barriers to this pursuit.

Method: A quantitative survey research methodology with a cross-sectional research design was adopted, where a 21-item web-based survey was used to survey 127 speech therapists, As and speech therapists and As from across the country. All participants were qualified and registered with the Health Professionals Council of South Africa (HPCSA). Ethical clearance and permission from relevant stakeholders were obtained. Data were analysed descriptively.

Results: The findings suggested that over half of the participants pursued their postgraduate studies to fulfil a personal goal and improve their knowledge, whilst others did it to develop expertise and for job opportunities. Participants highlighted that a lack of time and funding, heavy workloads and bad experiences during their undergraduate studies were the main barriers to pursuing postgraduate studies. Whilst community service was not a barrier per se, participants felt that it delayed them from beginning their postgraduate studies immediately.

Conclusion: The findings of this study highlighted the urgent need for institutions of higher learning, government and other stakeholders to provide the necessary support for SLPs and As in South Africa to pursue postgraduate studies.

Background: Children from under-served communities are at risk for delayed spoken language and literacy development. Under-served preschools frequently contend with lack of resources, especially with regard to access to age-appropriate storybooks and/or print resources. Environmental print is a cost-effective material that can be used to stimulate emergent literacy skills. In the context of under-served communities, a collaborative approach and mentorship between preschool teachers and Speech-Language Therapists (SLTs) promote language and literacy development.

Objectives: This article's purpose is two-fold; firstly, to discuss the use of environmental print as a stimulus material to promote emergent literacy in preschoolers in under-served preschools. Secondly, to promote the SLT's involvement in such education initiatives.

Method: A mixed-method, comparative intervention research design, was reported in this article. A pre- and post-test design was employed, with data collected before and after a teacher-based intervention.

Results: Participants in the intervention group displayed increased scores on the Concepts About Print (CAP) assessment, participants in the comparison group showed no change in scores using the same assessment over the same time period.

Conclusion: A short-term, teacher-based intervention using environmental print with SLT mentoring and collaboration promoted preschool children's emergent literacy skills. Implications include the value of using environmental print as a teaching material and the positive impact of collaboration between SLTs and teachers to promote emergent literacy in preschool children.

Background: Age-Related Hearing Loss (ARHL) is the most widespread sensory disorder in the elderly. Poor audiological support within retirement homes is one of the fundamental issues impacting the Quality of Life (QoL).

Objectives: The objectives of this study were to: (1) Identify the presence of hearing impairment through a hearing screening test battery in a sample of elderly participants residing in three retirement homes. (2) Determine the psychological, communication-related and social impact of the hearing impairment on the QoL in a sample of elderly participants residing in retirement homes.

Method: A prospective cross-sectional research design with quantitative methods of data analysis was used to obtain data from 70 elderly participants (mean age = 79 years, 79% were female). Ten of them used hearing aids. Hearing screening was conducted using otoscopy, tympanometry and air conduction screening (500 Hz-4 kHz). The World Health Organization Quality of Life (WHOQoL) questionnaire was adapted and utilised for the present study.

Results: Findings revealed that 77% of the sample obtained a refer result from the hearing screening protocol indicating a high presence of hearing impairment. Twenty-nine per cent (n = 16) of the participants felt depressed, worried and anxious because of their hearing loss and 20% of participants felt unaccepted by their significant others as a result of their hearing impairment. Hearing difficulties were significantly associated with a reduced QoL (p = 0.045). Eight of the 10 participants who wore hearing aids reported an overall improvement in QoL since receiving and utilising their hearing aids and 20% (n = 2) of hearing aid users reported challenges with maintaining their hearing aids.

Conclusion: The findings of this study emphasised the need for an increased role for audiological services provided by audiologists within retirement homes, thereby contributing to an improved QoL.

Background: SARS-CoV-2 (COVID-19) has had a significant impact on every South African but more specifically healthcare professionals, including speech-language pathologists (SLPs). In response to the COVID-19 pandemic, South Africa implemented a nationwide lockdown as confirmed cases continued to rise. Understanding the impact of COVID-19 on SLPs has a three-fold purpose: to re-evaluate service provision, service delivery platforms and to identify the need for support to SLPs during a time of crisis. It is also crucial in guiding how policies and interventions need to be modified.

Objectives: The study aimed to better understand how the workspace of SLPs in hospitals was impacted by COVID-19, how they experienced this process and the implications for them as healthcare professionals in both the private and public sector throughout South Africa.

Methodology: An exploratory cross-sectional study design was used to meet the aims of the study. Thirty-nine SLPs from different provinces in South Africa, working in government and private hospitals during COVID-19, responded to the online survey. Results were analysed using descriptive statistics and thematic content analysis.

Results: SLPs' roles, responsibilities and service delivery were impacted by COVID-19. It was necessary for typical outpatient therapy services to be modified; there were changes to the role of the SLP in the hospital and inpatient services were curtailed.

Conclusion: This study provides insightful information to SLPs employed in hospitals to know that they are experiencing similar challenges. It also confirms the resilience of healthcare professionals, including SLPs, when faced with novel and unprecedented situations.

Background: The Health Professions Council of South Africa (HPCSA) issued early hearing detection and intervention guidelines, which has universal newborn hearing screening (UNHS) as one of the important goals. Despite established evidence of the importance of UNHS globally, there has been no mandated formalised and standardised implementation as yet in South Africa.

Objectives: The aim of this study was to describe the outcomes of newborn hearing screening (NHS) in an academic secondary level hospital in Johannesburg, South Africa.

Methods: This was a prospective non-experimental feasibility study over a 3-month period, involving conducting hearing screening of 121 neonates. Audiologists conducted a risk factor assessment, otoscopic examinations and distortion product otoacoustic emissions (DPOAEs) screening on each neonate, with follow-up appointments for re-screening and diagnostic audiological assessments for all neonates with refer findings. Data were analysed using STATA intercooled version 11©, through both descriptive and inferential statistics (Fisher's exact test), with significance established where p-values less than 0.05 were considered statistically significant.

Results: Of the 121 neonates screened, the majority (75%) were screened in the first 24 h of life. A high refer rate (47%) of the total sample was found on DPOAE screening. No maternal or neonatal risk factors were found to be significantly associated with refer findings.

Conclusion: Findings contribute towards the existing evidence base that raises implications for successful implementation of NHS programmes in public healthcare in South Africa. Screening protocols need to consider the timing of screening, the measures and procedures adopted in the screening protocols, as well as the follow-up strategies.

Background: Ototoxicity linked to medications used to treat tuberculosis (TB) remains a global challenge.

Objectives: The aim was to describe the audiological function in a group of adults with drug-resistant tuberculosis (DR-TB) on bedaquiline (G-BDQ) treatment attending a TB hospital in South Africa and compare this with patients on kanamycin (G-KCIN).

Methods: A quantitative paradigm was adopted within a non-experimental retrospective record review design. The sample consisted of 30 records of adults with DR-TB between the ages of 18 and 50 years, recruited from a Tropical Diseases Hospital in South Africa. Data were analysed through both descriptive and inferential statistical measures.

Results: Clear and statistically significant differences in the audiological function were found between the two groups. The group receiving G-KCIN presented with ototoxicity that was clearly demonstrated by sensorineural hearing loss of high-frequency worsening of thresholds in over 73% of the records, which was statistically (p 0.05) and clinically significant, over the three testing sessions, demonstrating the cumulative effects of dosage. Increased evidence of tinnitus was also found in this group. The group receiving G-BDQ presented with neither statistically (p 0.05) nor clinically significant changes in hearing thresholds across all frequencies over the same monitoring timeframe. Additionally, only one report (7%) of tinnitus was found in this group.

Conclusion: The results indicating that bedaquiline does not cause hearing loss when compared with G-KCIN highlight the need for increased availability of bedaquiline for the treatment of DR-TB within the South African context, to preserve both the quantity and quality of life of those infected.

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.
