“…On average, caregivers suspected hearing loss by 11.3 months of age, with a delay of 5.3 months until eventual diagnosis. In spite of the age of parental suspicion corresponding with a Nigerian sample [61], this study's results indicate ages of suspicion and diagnosis much earlier than recent South African reports [23][24][25]. Children with profound hearing losses are however known to be identified at earlier ages than children with less severe degrees of hearing loss, since the symptoms of profound hearing loss are more apparent and may prompt parents to seek audiological evaluation sooner [34].…”

“…A recent study by Butler et al [1] found that the median age of diagnosis of congenital hearing loss (CHL) in a public sector tertiary referral hospital was 3.71 years. This is in sharp contrast to the Health Professions Council of South Africa (HPCSA) recommendation [2] that diagnosis of hearing loss be achieved by 4 months of age (for clinic-based hearing screening programmes) and the international standard recommendation of 3 months of age (for hospital-based hearing screening programmes).…”

Age of diagnosis of congenital hearing loss: Private v. public healthcare sector

et al. 2015

Corresponding author: I Butler (butlerirt@ufs.ac.za)Background. The age of diagnosis of congenital hearing loss is one of the most important determinants of communication outcome. A previous study by the lead author had evaluated the performance of the public health services in Bloemfontein, South Africa (SA), in this regard. This study aimed to examine whether the private health services in the same city were any better. Objective. To determine whether the age of diagnosis of congenital hearing loss (CHL) in children seen in the private healthcare sector in Bloemfontein, Free State Province, SA, was lower than that in the public healthcare system in the same city. Methods. A comparative study design was utilised and a retrospective database review conducted. Data obtained from this study in the private healthcare sector were compared with data from a previous study in the public healthcare sector using the same study design.Results. Forty-eight children aged <6 years with disabling hearing impairment (DHI) were identified in the private healthcare sector during the study period; 33/47 (70.2%) did not undergo hearing screening at birth. The median age of diagnosis of DHI in the private healthcare sector was 2.24 years, and this was statistically significantly lower than the median age of diagnosis of 3.71 years in the public healthcare sector (p<0.0001; 95% confidence interval (CI) 0.99 -2.0). The median age of diagnosis of CHL in the private healthcare sector was 3.01 years in children who were not screened at birth, and 1.25 years in those who were screened at birth. This difference was statistically significant (p<0.01; 95% CI 0.72 -2.47). We also compared the median age of diagnosis of CHL in children from the private healthcare sector who were not screened at birth (median 3.01 years) with that in children in the public healthcare sector (median 3.71 years). This difference was statistically significant (p<0.01; 95% CI 0.41 -1.56). Conclusions. Children in the Free State are diagnosed with CHL at a younger age in the private healthcare sector than in the public healthcare sector. With the social and economic benefits of early intervention in cases of DHI well established internationally, SA healthcare providers in both the public and private sectors need to develop screening, diagnostic and (re)habilitation services for children with hearing impairment.

Objective: Postnatal visits at community-based midwife obstetric units (MOUs) have been proposed as an alternative primary healthcare screening platform in South Africa. This study evaluated the outcomes of distortion product otoacoustic emissions (DPOAEs) and automated auditory brainstem response (AABR) screening conducted by a dedicated nonprofessional screener at a community-based MOU in the Western Cape, South Africa.Methods: Universal newborn hearing screening (UNHS) at a community-based MOU was evaluated over a 16-month period. A dedicated non-professional screener was trained to follow a two-stage screening protocol targeting bilateral hearing loss. A two group comparative design was used alternating AABR (Maico MB11 BERAphone TM) and DPOAE (Bio-logic AuDX I) technology on a daily basis. Infants referring the initial screen received a follow-up appointment in two days' time and were rescreened with the same technology used at their first screen.Those referring the second stage were booked for diagnostic assessments.Results: 7452 infants were screened including 47.9% (n=3573) with DPOAE and 52.1% (n=3879) with AABR technology. Mean age at first stage screen was 6.1 days. The initial bilateral referral rate was significantly lower for AABR (4.6%) compared to DPOAE (7.0%) and dropped to 0.3% and 0.7% respectively following the second stage screenings. First rescreen and initial diagnostic follow-up rates of 90% and 92.3% were obtained for the DPOAE group and 86.6% and 90% for the AABR group. Follow-up rates showed no significant difference between technology groups. Diagnostic assessment revealed a higher prevalence rate for bilateral sensorineural hearing loss among the AABR group (1/1000) compared to the DPOAE group (0.3/1000). Screening technology had no significant influence on daily screening capacity (23 AABR/day; 24 DPOAE/day). 3Conclusions: Postnatal visits at community-based MOUs create a useful platform for hearing screening and follow-up. AABR technology with negligible disposable costs provides opportunity for AABR screening to be utilised in community-based programmes. AABR screening offers lower initial referral rates and a higher true positive rate compared to DPOAE.
