“…There has been a growing interest and advocacy recently for creating equal opportunities for infants with hearing loss in developing countries through early detection and intervention programs [8], [18] and [35]. This has also become evident in South Africa where a growing interest is reflected in the dissemination of a Hearing Screening Position Statement by the Health Professions Council of South Africa [10], [12] and [36].…”

Summary ObjectiveEarly Hearing Detection and Intervention (EHDI) programs are being established as part of the public health systems in increasing numbers of countries. In developing countries, however, little progress has been made towards implementing NHS programs and South Africa's public and private health care sectors is no exception.The current study presents the first report on a hospital-based UNHS program conducted in the South African private health care sector to provide preliminary results towards advocating for and guiding future programs. MethodsA retrospective study of a UNHS program at a private hospital in urban Gauteng, South Africa over a 4 year period of time was performed. Screening was conducted with Transient Evoked Otoacoustic Emissions (TEOAE) with a rescreen recommended within 6 weeks if referred. Diagnostic audiological assessments were performed on those infants referring the rescreen. The discharge screening costs were subsidized through the hospital birthing package for the first 22 months of the program. openUP (September 2007) ResultsSix thousand two hundred and forty-one newborns were screened from 13,799 hospital births during the first 4 years. Ninety-four percent of these infants were from the well-baby nurseries. During the initial 22 months, whilst the service was subsidized as part of the hospital birthing package, coverage of 75% was attained compared to 20% during the subsequent 26 months. The overall referral rate for the screening program across the 4 years was 11.1% but referral rates decreased by between 2 and 4% for each year of program existence with a 5% rate in year 4. Only 32% of the rescreens were completed at the hospital and no data was available for the remaining infants because parents were provided a choice of follow up centers.Referral for a diagnostic assessment after the rescreens at the hospital was predictive of sensorineural hearing loss in one-third of cases and the estimated prevalence was 3 in every 1000. ConclusionsScreening coverage in the current study was not adequately high and can be attributed to insufficient parental knowledge to make an informed decision. Improvements in program efficiency over time also suggest that pilot programs must be monitored over sufficiently long periods of time to allow observations of optimal efficiency. Initial referral rates and prevalence data indicate a large hearing loss burden and the capacity to implement increasingly efficient programs in South Africa.

“…In developing countries, in contrast, the detection of HL remains a passive process and occurs as a result of concerns regarding observed speech and language delays or unusual behavior (Theunissen & Swanepoel, 2008;Swanepoel, Störbeck & Friedland, 2009;Olusanya, 2004). Although the WHO encourages countries to increase prevention efforts and improve access to Early Hearing Detection and Intervention (EHDI) (WHO, 2010), very few developing countries have any systematic NHS programs.…”

Abstract:Objective: To determine the status of early intervention services provided to children who are deaf or hard of hearing and their parents/caregivers from birth to five years of age at two main state hospitals in Riyadh, Saudi Arabia, based on their parents' perceptions. Method: A descriptive quantitative research design was used to determine the status of early intervention services for deaf or hard of hearing children in Saudi Arabia based on their parents' perceptions. Semistructured interviews based on a questionnaire were conducted with 60 research participants from two main state hospitals where early detection and intervention services are provided. A purposive sampling technique was employed. Descriptive and inferential statistical analyses were performed on the data collected. Results: The participants' children were diagnosed at a substantially late age, resulting in delayed ages for initial hearing aid fitting and enrollment in early intervention services. A significant relationship was found between the residential area of the participants and timely access to intervention services. The results indicated that participants residing in Riyadh were fitted with hearing aids and enrolled into EI services earlier than those living outside of Riyadh. The delivery of information also emerged as a weakness in the EI system for the majority of participants.

“…The preliminary guidelines for interpreting 1000 Hz tympanometry hold significant promise for accountable application of the technique in neonatal screening programmes but require further normative studies on significant numbers of subject samples. This demand for more normative data is becoming increasingly important with the implementation of widespread UNHS programmes in developed and developing countries [16][17][18][19] . This study therefore investigated middle ear functioning in a sample of neonatal ears in order to describe normative data for high frequency immittance measurements using a 1000 Hz probe tone.…”

Conclusion. High frequency immittance measurements demonstrate promise in clarifying middle ear status for neonates but age-and gender-specific norms should be consulted. Objective. To describe high frequency immittance measurements using a 1000 Hz probe tone for a sample of 278 neonatal ears (0-4 weeks of age) in order to compile normative tympanometric and acoustic reflex criteria. Subjects and methods. Assessment of neonatal ears included 1000 Hz probe tone immittance measurements (tympanograms and ipsilateral acoustic reflexes), and distortion product oto-acoustic emission (DPOAE) screening. Results were compared and normative values were compiled for immittance measures in ears controlled for normal middle ear functioning (n=250). Results. Comparison of immittance results to OAE screening outcome provides estimates of sensitivity and specificity for middle ear fluid with tympanometry of 57% and 95%, and 57% and 90% for acoustic reflex presence, and 58% and 87% for combined tympanogram and acoustic reflex results, respectively. Normative data indicate that static peak admittance values differ significantly across gender and age with the 5th percentile cut-off value for the entire sample at 1.4 mmho. The 90% range of tympanic peak pressure normative values increases with increasing age from 140 daPa for neonates 1 week of age to 210 daPa for neonates 2-4 weeks of age. Acoustic reflexes were elicited at 93±9 dB with a 90% normality range of 80-105 dB.
