Lessons From an Exploratory Qualitative Survey on Simulation Opportunities for Clinical Education in Speech-Language Pathology and Audiology in South Africa.

Phenomenon: This study explored experiences of simulation-based clinical education in the Speech-Language Pathology and Audiology professions in South Africa, a Global South context where research on this topic is limited. In this context, the COVID-19 pandemic brought simulation to the forefront of clinical education as a training solution when in-person encounters were impossible. As these simulation-based training approaches gain traction, with continued use post-pandemic, it is important to understand how they are currently being used so that appropriate support can be offered to ensure their efficiency and success in the future. Approach: We distributed a survey to South African university departments offering Speech-Language Pathology and Audiology training, inviting participation from students across years of study and clinical educators. Data were collected between October 2022 and February 2023. Twelve responses were received: three from clinical educators and nine from students. We analyzed the responses using descriptive statistics and a domain summary approach. Findings: Simulated activities were implemented as options for clinical education in South African Speech-Language Pathology and Audiology (SLP/A) programs during the pandemic, albeit in a somewhat haphazard way depending on available resources, often with limited preparation or guidance. Some universities have continued using aspects of simulation training post-pandemic. Insights: Our findings, although preliminary, are somewhat consistent with Global North literature, particularly regarding barriers and challenges to implementing these approaches in clinical education. We offer suggestions for enhancing the support of simulation-based clinical education in our context.

Audiology Students' Clinical Communication During Simulated Peer Role Play Consultations: An Exploratory Study.

PURPOSE: The objectives of this study were to describe the clinical communication practices of student audiologists during case history taking and feedback giving using simulated peer role play consultations and to explore whether clinical communication skills outcomes can be achieved through simulated peer role play. METHOD: An exploratory, qualitative research design was used for this pilot study. A total of four simulated peer role play consultations were video-recorded, comprising two adult diagnostic audiology case scenarios. Eight online interviews were conducted with the student participants following the simulated audiological consultation. Analysis of the video-recorded sessions incorporated an interactional sociolinguistic focus, and interviews were analyzed using inductive thematic analysis. RESULTS: Findings from the video analysis and interviews were triangulated, with a specific focus on establishing commonalities in terms of communication skills of student clinicians, reflections of their own skills, and the simulated peer patient's reflections on the student clinician's skills. Although variation was noted in terms of case history taking skills, feedback giving was similar among all student clinicians. These communication practices are consistent with findings from related literature on consultations with real patients. Student clinicians reflected on feedback giving as more challenging than case history taking, with room for improvement suggested by the simulated peer patients. CONCLUSIONS: Our findings highlight key questions regarding the use of peer simulation in facilitating the development of communication skills for audiological consultations among student audiologists. We discuss some considerations for using this approach to clinical training more effectively. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.25492804.

Experiences of parents of children with cochlear implants in South Africa: an exploratory study.

PURPOSE: Cochlear implantation is a well-established option for early intervention. Children with hearing impairment and their parents are users of intervention services, with parents being more suited to provide insight into their experiences. The purpose of the current study was to describe the experiences of parents of children with cochlear implants (CIs) in the South African context. METHODS: A qualitative research design was employed. Non-probability, purposive sampling was used. Seven, online semi-structured interviews were conducted with parents of children with CIs. Data were analysed using inductive thematic analysis. RESULTS: Participants expressed feelings of certainty and assurance in the CI journey. Participants extended gratitude to the healthcare professionals involved in their children's CI journey. Feelings of doubt and stress were noted when coming to terms with the decision of cochlear implantation and financial stressors were noted as a challenge. Many participants found it challenging transitioning their children into school. CONCLUSIONS: Parents conveyed having no regrets with their decision of cochlear implantation for their child and were grateful for the support provided by healthcare professionals. However, financial, and educational challenges remain. Findings suggest the need for more financial support for cochlear implantation in South Africa, and for adequate inclusive educational settings.

Parental involvement and family-centred care are important to the success of cochlear implantation in children.Parents do report positive experiences with regard to cochlear implantationFinancial stressors and schooling remain a challenge for parents to navigate through the CI journey.Counselling, provision of information, and ongoing support by healthcare professionals is recommended to assist parents in making informed decisions regarding cochlear implantation and schooling.

Roles and reported practices of paediatricians in the early identification and monitoring of hearing impairment in high-risk newborns and infants.

BACKGROUND: The paediatrician is often the first professional who provides care for the infant and their families, hence having a vital role in the early identification and intervention of hearing impairment. OBJECTIVE: This study aimed to identify the role and reported practices of paediatricians in the early identification and monitoring of hearing impairment in high-risk newborns and infants. METHODS: The sample comprised 30 paediatricians in South Africa. Data were collected by means of an online survey and analysed using descriptive statistics. RESULTS: Variability was noted in the early identification protocols, with most participants conducting objective measures. Although most participants refer newborns and infants for audiological evaluation when hearing impairment is suspected, there is variability with regard to the age at which they are referred. Approximately 98% of participants believe that they form part of the multidisciplinary team; however, only 69% reported that they have actually been part of a multidisciplinary team. CONCLUSIONS: Paediatricians had sufficient knowledge regarding the assessment of hearing impairment and their role in the early hearing detection and intervention programme. There is however a need for information sharing regarding appropriate hearing screening measures.

A Systematic Review of Ethics Knowledge in Audiology Literature: A Follow-Up Study (2011-2020).

PURPOSE: This systematic review aimed to update and explore the extant literature (2011-2020) regarding ethics knowledge in audiology and to compare the findings to an earlier study (2001-2010). METHOD: This systematic review employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RESULTS: MEDLINE, CINAHL, ERIC, MasterFILE Premier, E-Journals, Africa-Wide information and Academic Search Premier electronic databases, and non-peer-reviewed papers in Seminars in Hearing yielded a total of 63 papers. Following systematic screening using inclusion and exclusion criteria, a total of 12 full-text papers were included in this review. Pertinent data and findings from the review were tabulated and analyzed using a qualitative, deductive approach. Results showed that the 12 papers were published in nine peer-reviewed journals with a predominantly social scientific approach. This differs from the earlier review that reported only five papers with a predominantly philosophical approach. However, both the current and earlier studies focused on the rehabilitation/management role of the audiologist. In the earlier study, the focus was on moral judgment (as one of the components of moral behavior), whereas this was the focus of only half of the papers identified in this study, with the remaining papers focusing on moral sensitivity and moral motivation. CONCLUSIONS: The focus of papers had evolved and continued to include more elements related to the multiple perspectives used to analyze and describe ethics research. The body of knowledge of ethics in audiology specifically expanded in the area of social scientific research, focusing on beneficence and nonmaleficence, including moral motivation and basing research on moral judgment with the emphasis on the rehabilitation/management and education/research/administration role of audiologists.

Students' Reflections During Training Workshops on Communication and Information Exchange in Audiology Consultations: An Exploratory Qualitative Study.

PURPOSE: This clinical focus article outlines various communication challenges and scenarios related to information giving encountered by a group of audiology students, as reflected on during a series of communication skills workshops. METHOD: We held two online training workshops during which students reflected on their clinical communication experiences and asked questions related to clinical scenarios. Third-year audiology students from a South African university participated in the workshops (17 in the first, 15 in the second). We analyzed these reflections using thematic analysis. RESULTS: Students' reflections related to four themes: (a) balancing information giving, (b) managing shared decision making, (c) managing linguistic differences, and (d) relating bad news. The first theme was heavily prioritized in students' reflections. Providing students with time to practice skills introduced in the initial communication skills workshop enabled further reflection in the subsequent workshop. We discuss these themes using specific examples raised by students. CONCLUSIONS: Our findings suggest that students first need to master basic information giving skills before they can move on to more advanced skills such as managing shared decision making, linguistic differences, and relating bad news. This study confirms that reflective skills need to be developed with students in an explicit manner, rather than as part of a hidden curriculum. Our approach to providing communication training and encouraging reflection on clinical experiences offers a starting point for clinical educators to support students in developing these skills.

Professional Guidelines and Reported Practice of Audiologists Performing Fall Risk Assessment With Older Adults: A Systematic Review.

PURPOSE: This systematic review aimed to explore the recommended fall risk assessment practices in audiology, identify audiologists' reported practices in fall risk assessment, and recognize the barriers and facilitators affecting fall risk assessment in clinical practice. METHOD: This systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RESULTS: CINAHL, PubMed, and gray literature yielded 262 articles. A total of 27 full-text articles were included in this review article. An additional 16 scope of practice and guideline documents were also reviewed. Pertinent data and findings from the review were tabulated and analyzed using a qualitative, inductive approach. CONCLUSIONS: Results revealed that despite fall risk assessment measures and protocols being mentioned, discussed, and reportedly implemented clinically in audiology literature, many audiologists are not conducting fall risk assessments clinically. The main challenges presented appear to be due to limited guidance within audiology documentation and inadequate training and knowledge of audiologists on fall risk factors and measures. This review article highlighted that all audiologists have an important role to play in reducing the global crisis of falls in older adults. However, without further research to aid in the development of standardization of documentation and training programs, we may continue to see a lack of awareness and education on fall risk and on the audiologist's role in the screening and early detection hereof.

Newborn and infant hearing screening at primary healthcare clinics in South Africa designated as National Health Insurance pilot sites: An exploratory study.

BACKGROUND: Primary healthcare (PHC) is the first point of entry, providing basic services to individuals. South Africa is in the process of re-engineering its PHC as part of National Health Insurance (NHI) plans to ensure universal healthcare coverage. AIM: This study aimed to establish whether newborn and infant hearing screening (NIHS) could be integrated into the re-engineering process of the PHC as part of the NHI framework. SETTING: The NHI pilot clinics in five provinces in South Africa. METHODS: A non-experimental, descriptive, cross-sectional survey research design was adopted. Questionnaires were sent to nursing managers, unit managers or acting managers at PHC facilities. Nineteen of these self-administered questionnaires were completed. Data were analysed using descriptive statistics. RESULTS: Immunisation services were the most common type of service offered at the clinics. Over a quarter of the respondents indicated that NIHS services were offered at their facility in the form of universal NIHS. Equipment was limited with a lack of valid and reliable screening measures. Only 2 (11%) respondents indicated budgetary resources. Follow-up and referral pathways were reported by 10 (53%) respondents, which did not include an audiologist. CONCLUSIONS: There is a need for careful and systematic planning in terms of early hearing detection programmes at PHC level. Planning needs to commence with considerations of who will perform NIHS, training of these personnel by audiologists and the role of the audiologist within the teams outlined in the NHI Bill.

The Impact of Pass/Refer Criteria in the Use of Otoacoustic Emission Technology for Newborn Hearing Screening.

Purpose The current study aimed to compare the specificity of transient evoked otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) in isolation and in combination, with varying pass/refer criteria for DPOAE technology. Method A longitudinal, repeated-measures design was employed. The current study sample comprised 91 of the initial 325 participants who returned for the repeat screening and diagnostic audiological assessment within a risk-based newborn hearing screening program. Results TEOAE screening had the highest specificity in comparison to DPOAE screening at the initial and repeat screening, irrespective of differences in DPOAE pass/refer criteria. DPOAE screening had a slightly higher specificity, with a three out of six rather than the four out of six frequency pass criteria. Conclusions Pass/refer criteria alone do not influence referral rates and specificity. Instead, consideration of other factors in combination with these criteria is important. More research is required in terms of the sensitivity and specificity of OAE screening technology using repeated-measures and diagnostic audiological evaluation as the gold standard.

What are the current practices employed by audiologists in early hearing detection and intervention in the South African healthcare context?

BACKGROUND: Universal access to early hearing detection and intervention (EHDI) forms part of the audiology community's goal. Evidence on current practices employed by South African audiologists in EHDI in order to ensure this universal access and success for children with hearing impairment is therefore required, hence this study. METHODS: A quantitative survey research methodology with a cross-sectional design was employed. An online survey was completed by 49 qualified audiologists and dually qualified speech therapists and audiologists. Data were analysed using descriptive statistics. RESULTS: Results identified gaps in the implementation of EHDI within the South African context. A total of 83.7% of the participants were involved in newborn hearing screening (NHS), with over half adopting the targeted screening approach instead of universal NHS services (UNHS). Capacity versus Demand challenges play a significant role in the lack of successful implementation of NHS with over 60% of the audiologists in the sample reporting that NHS is and should only be conducted by audiologists only; with minimal evidence of task shifting found. No standardised screening protocol was found, with challenges around budget allocation for EHDI revealed. CONCLUSIONS: Although progress has been noted, a) gaps between public and private healthcare sector resources allocations and availability, b) limited contextually responsive strategic planning, as well as c) lack of translation of knowledge, policies and guidelines into practice, are glaring areas that require attention by the South African audiology community.

Risk factors for hearing impairment in neonates in South Africa: scoping the context for newborn hearing screening planning.

PURPOSE: The current study aimed to describe the medical case history factors in a group of neonates admitted to high care and Kangaroo Mother Care wards at two hospitals in Gauteng, South Africa and to explore the relationship between specific case history factors and audiological outcomes. METHODS: This study was part of a bigger study titled "Early detection of hearing loss: exploring risk-based hearing screening within a developing country context" where all case history data were recorded from participant medical files at the time of an initial hearing screening, through the use of a case history form that was developed for this study. Results were analyzed using descriptive statistics. The relationship between case history factors and audiological outcomes was analyzed using Fisher's exact test. RESULTS: Findings revealed that, of all the case history data, preterm birth (95.7%), exposure to ototoxic medication (87.7%), neonatal jaundice (NNJ) (80.6%), and birthweight below 1500 g (66.7%) were the most frequently occurring case history factors in this South African sample. No statistically significant association was found between these frequently occurring case history factors and the repeat hearing screening outcomes in this sample. CONCLUSIONS: Risk factors for hearing impairment cannot be viewed in isolation but should be considered in relation to their interaction with multiple other risk factors. Contextually understanding the profile of high risk has implications for medical intervention, as well as for the field of Audiology where planning for early identification and intervention services for hearing impairment is vital. Such contextually relevant evidence allows for a snap shot of how this population presents, what their needs and requirements are, and their possible future requirements; hence, raising important planning implications for the department of health and for targeted newborn hearing screening as well as early childhood intervention within the South African context.

An Integrative Review of Current Practice Models and/or Process of Family-Centered Early Intervention for Children Who Are Deaf or Hard of Hearing.

Over the past few decades, there has been an increasing shift toward emphasizing the importance of the child's family taking an active role in the habilitation process through family-centered early intervention (FCEI) programs. Accordingly, the Health Professions Council of South Africa recommends that early intervention services following confirmation of hearing loss must be family-centered within a community-based model of service delivery that is culturally congruent. The aim of this study was to explore and document current evidence reflecting trends in FCEI for children who are deaf or hard of hearing (DHH) by identifying and describing current practice models and/or processes of FCEI for these children. This study describes our first steps in formulating a framework for FCEI for children who are DHH in South Africa. An integrative literature review was conducted. Sage, Science Direct, PubMed, and Google Scholar databases were searched for studies published in English between January 2009 and January 2019 reporting on FCEI programs for children who are DHH. Studies that focused on the following were excluded from the study: speech and language outcomes of children, youth, and adults who are DHH; education for children who are DHH; universal newborn hearing screening; professionals' roles in early hearing detection and intervention; diagnosis of hearing loss; and sign language. Kappa statistics were performed to determine agreement between reviewers. Twenty-two studies were included in the review. Cohen's kappa revealed a substantial agreement (κ = 0.8) between reviewers for data extraction and synthesis in terms of the articles that met the criteria for inclusion in the review. Findings were discussed under 5 themes: caregiver involvement; caregiver coaching/information sharing; caregiver satisfaction; challenges with FCEI; and telehealth. Generally, there is sufficient evidence for FCEI, with caregivers indicating the need for full involvement in their children's care. Methods of caregiver involvement involving caregiver coaching/information sharing need to be culturally and linguistically appropriate, with sensitivities around time and manner. This increases caregiver satisfaction with intervention programs and improves outcomes for children who are DHH. Challenges identified by the studies raise implications for early hearing detection and intervention programs, as well as Departments of Health and Social Welfare. These included logistical challenges, professional-related challenges, and caregiver-related challenges. Various aspects of FCEI have been reported in the review. Findings of these studies have significant implications for the formulation of quality FCEI programs to ensure contextually relevant and contextually responsive care of children who are DHH.

"What's Going on With My Ears?": Some Reflections on Managing Uncertainty in the Audiology Consultation.

Purpose Feedback sessions after audiology consultations predominantly involve information counseling or patient education, where the patient is informed about their hearing status and possible management options. Effective communication is vital to ensure that information about the hearing impairment, recommendations, and/or management options is appropriately provided and understood by patients and that patient needs and expectations from the session are met. This research note reports on an exploratory study that sought to describe communication in follow-up audiological consultations within a context where ototoxicity monitoring is routine practice. Method Six interactions between patients and audiologists were video-recorded at an in-patient treatment facility for drug-resistant tuberculosis in Johannesburg and analyzed using a sociolinguistic approach. Semistructured interviews were also conducted with participants and analyzed using content analysis. Results These interactions differed considerably to other audiology consultations we have analyzed in terms of aspects such as the length of the interaction and the type of information given to patients. We observed a substantial amount of mitigative, vague, and exaggerated language in these interactions. Conclusions In this research note, we offer some reflections on this data set using a lens of uncertainty management theory and explore factors within the broader context that may contribute to the interactional features observed in the current study. Overall findings suggest the need for clinicians to be trained to embrace and address uncertainty rather than avoid it within challenging clinical encounters.

Communication and school readiness abilities of children with hearing impairment in South Africa: A retrospective review of early intervention preschool records.

BACKGROUND:  The national prevalence of hearing impairment in South Africa is estimated to be four to six in every 1000 live births in the public health care sector. An undetected hearing impairment in childhood can lead to delayed speech and language development as well as put the child at risk of not achieving the necessary school readiness abilities that will enable them to achieve academic success. However, through early hearing detection and intervention services, children with hearing impairment can develop communication and school readiness abilities on par with children with normal hearing. OBJECTIVE:  The aim of the study was to describe communication and school readiness abilities of children who were identified with hearing impairment and enrolled in early intervention (EI) preschools in Gauteng. METHODS:  Within a descriptive research study design, a retrospective record review was conducted on files of eight children, ranging in age from 9 years and 7 months to 12 years and 7 months, identified with a hearing impairment and enrolled in EI preschools in Gauteng, South Africa. Descriptive statistics were used to analyse the data, using frequency distribution and measures of central tendency. RESULTS:  Current findings revealed that children with hearing impairment who were enrolled in EI preschools in Gauteng were identified late. This consequently led to delayed ages at initiation of EI services when compared to international benchmarks and the Health Professions Council of South Africa's (HPCSA) guidelines of 2018. Consequently, participants presented with below average communication and school readiness abilities, which are characteristic of hearing impairment that is identified late. CONCLUSIONS:  Transference of current contextually relevant research findings into practice by both the Department of Health and the Department of Basic Education forms part of future directions from this study. This conversion of research findings into service delivery must be conducted in a systematic manner at all levels in these two sectors to facilitate achievement of Early Hearing Detection and Intervention (EHDI), resulting in better communication and school readiness outcomes.

Hearing impairment detection and intervention in children from centre-based early intervention programmes.

The study aimed to describe ages at identification and initiation of early intervention (EI) services for children enrolled in centre-based EI programmes in Gauteng, as well as to describe the nature of EI services that the children received. The researchers conducted retrospective record reviews of the EI programme files. In addition, caregivers of eight children identified with hearing impairments and enrolled in centre-based EI programmes in Gauteng completed a newly constructed questionnaire. The caregiver questionnaire produced data pertaining to the child's family demographics, background information and schooling history. Descriptive statistics were used to analyse the data, using frequency distribution and measures of central tendency. None of the children received newborn hearing screening services, thus they were identified late following maternal suspicion of hearing impairment. Late identification of the hearing impairment resulted in suboptimal initiation of EI services. All the children received aural habilitation and/or speech-language therapy services. These findings indicate that there is a great need for the establishment of widespread early hearing detection and intervention programmes that will lead to earlier identification of infant and childhood hearing impairment and timely initiation of EI services.

Noise-induced hearing loss: what South African mineworkers know.

PURPOSE: The current study aimed to investigate the knowledge of mineworkers regarding noise-induced hearing loss in the South African gold and non-ferrous mining subsectors. METHOD: A descriptive research design was adopted. Semi-structured interviews were conducted with 90 participants who comprised managers, supervisors and miners. Data were analysed qualitatively. RESULTS: The majority of participants (97%) acknowledged working in a noisy environment and demonstrated knowledge of the consequences of this exposure on their hearing function. Although all but one participant indicated having known the importance of using hearing protection devices (HPDs), less than 50% reported consistent use of HPDs. This highlights gaps in education and training, as well as implementation monitoring. All participants reported knowledge regarding the importance of hearing monitoring, but a lack of understanding of their test results. CONCLUSIONS: Current findings contribute towards evidence regarding internal barriers to effective application of best practice in hearing conservation programmes (HCPs). Findings highlight the important role of occupational audiologists in South African mines and the need for individualized education during medical surveillance to enhance efficacy of HCPs. Comprehensive education and training programmes regarding noise exposure and exposure measurements with consistent HPD efficiency assessments are recommendations emanating from these findings.

Audiological follow-up in a risk-based newborn hearing screening programme: An exploratory study of the influencing factors.

BACKGROUND:  Follow-up return rate in Early Hearing Detection and Intervention (EHDI) programmes is of specific importance as it ensures that benchmarks are met and that no child with suspected hearing loss is left unidentified. OBJECTIVES:  The aim of this study was to determine the factors influencing audiological follow-up of high-risk infants in a risk-based newborn hearing screening programme. METHOD:  A non-experimental, exploratory, qualitative research design was employed. Purposive sampling was used. The study was conducted at a secondary level hospital in the public health care sector in South Africa. Participants comprised 10 caregivers (age range 26-40 years) of infants who had been enrolled in a risk-based newborn hearing screening programme, and returned for follow-up appointments. Data were collected using semi-structured interviews. Responses were recorded by the researcher and a colleague to ensure rigour and trustworthiness of findings. Data were analysed using thematic analysis for open-ended questions and descriptive statistics for the closed-ended questions. RESULTS:  The most common positive contributors that facilitated participants' attendance at follow-up appointments were: having friendly audiologists; a clear line of communication between caregiver and audiologist and a reminder of the appointment. The most significant perceived challenge that participants described in returning for the follow-up appointment was living in far proximity from the hospital. CONCLUSION:  Findings of the study revealed that influencing factors on follow-up return rate are demographic, socio-economic, and interpersonal in nature and further suggested the need for an all-inclusive appointment day. It may be of importance to not only look at what is being done to improve the follow-up return rate but also how it should be done in terms of professional-to-patient communication and interactions.

Newborn hearing screening protocols and their outcomes: A systematic review.

OBJECTIVE: To conduct a review of the most current research in objective measures used within newborn hearing screening protocols with the aim of exploring the actual protocols in terms of the types of measures used and their frequency of use within a protocol, as well as their outcomes in terms of sensitivity, specificity, false positives, and false negatives in different countries worldwide. METHODS: A systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Electronic databases such as PubMed, Google Scholar and Science Direct were used for the literature search. A total of 422 articles were identified, of which only 15 formed part of the current study. The 15 articles that met the study's criteria were reviewed. Pertinent data and findings from the review were tabulated and qualitatively analysed under the following headings: country; objective screening and/or diagnostic measures; details of screening protocol; results (including false positive and negative findings, sensitivity and/or specificity), conclusion and/or recommendations. These tabulated findings were then discussed with conclusions and recommendations offered. RESULTS: Findings reported in this paper are based on a qualitative rather than a quantitative analysis of the reviewed data. Generally, findings in this review revealed firstly, that there is a lack of uniformity in protocols adopted within newborn hearing screening. Secondly, many of the screening protocols reviewed consist of two or more tiers or stages, with transient evoked otoacoustic emissions (TEOAEs) and automated auditory brainstem response (AABR) being most commonly used. Thirdly, DPOAEs appear to be less commonly used when compared to TEOAEs. Lastly, a question around routine inclusion of AABR as part of the NHS protocol remains inconclusively answered. CONCLUSIONS: There is sufficient evidence to suggest that the inclusion of AABR within a NHS programme is effective in achieving better hearing screening outcomes. The use of AABR in combination with OAEs within a test-battery approach or cross-check principle to screening is appropriate, but the inclusion of AABR to facilitate appropriate referral for diagnostic assessment needs to be systematically studied.

Objective Hearing Screening Measures: An Exploration of a Suitable Combination for Risk-Based Newborn Hearing Screening.

BACKGROUND: The ideal hearing screening measure is yet to be defined, with various newborn hearing screening protocols currently being recommended for different contexts. Such diverse recommendations call for further exploration and definition of feasible and context-specific protocols. PURPOSE: The aim of the study was to establish which combinations of audiological screening measures provide both true-positive (TP) and true-negative (TN) results for risk-based hearing screening, at and across time. RESEARCH DESIGN: A longitudinal, repeated-measures design was employed. STUDY SAMPLE: Three-hundred and twenty-five participants comprised the initial study sample. These participants comprised newborns and infants who were discharged from the neonatal intensive care unit and high care wards to "step down" wards at two public sector hospitals within an academic hospital complex. DATA COLLECTION AND ANALYSIS: Transient evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic emissions (DPOAEs), and automated auditory brainstem response (AABR) were conducted at the initial and repeat hearing screening. Diagnostic audiological assessments were also conducted. Results from combinations of audiological screening measures at the initial and repeat hearing screening were analyzed in relation to the final diagnostic outcome (n = 91). Participants were classified as presenting with an overall "refer" if the outcome for any one test was "refer." The overall screening outcomes for different test combinations were compared using McNemar's test for paired data. Proportions across different test combinations were compared by the z-test for proportions. RESULTS: Because of the absence of participants with hearing loss in the current study sample, analysis could only be conducted in relation to TN findings (specificity) and not TP findings (sensitivity). The percentage of TN findings was highest at the repeat hearing screening using any test or combination of tests when compared with findings from the initial hearing screening. TEOAE combined with AABR (TEOAE/AABR) (p < 0.0001), DPOAE combined with AABR (DPOAE/AABR) (p < 0.0001), and the combination of all three screening measures (p < 0.0001) yielded the highest percentage specificity at the repeat hearing screening when compared with the initial hearing screening. CONCLUSIONS: The best specificity was noted at the repeat hearing screening. Within a resource stricken context, where availability of all screening measures options may not be feasible, current study findings suggest the use of a two-stage AABR protocol or TEOAE/AABR protocol.

Early hearing detection and intervention: Reflections from the South African context.

For researchers and clinicians in developing contexts like South Africa, the establishment of universal newborn hearing screening (UNHS) programmes is something which we have strived to achieve. However, we need to ask the question as to whether we have attempted to view our ultimate goal of achieving mandated UNHS programmes from the perspective of the South African healthcare system as a whole. The current manuscript is aimed at providing an overview of audiological services within a broader context, with reflections from a South African perspective, and a suggestion to consider alternatives to UNHS, particularly in the South African public health care sector.
