“…Automated technologies may make universal screening for CP using GMA feasible. Newborn hearing screening [90] can be used as a precedence for universal screening. Although, it is recognized that considerable human resources would be required to relay assessment results compassionately if universal screening using GMA was implemented.…”

Since the 1800s, there have been calls in the literature for the early diagnosis of cerebral palsy (CP). However, diagnosis still often occurs late, from 12 to 24 months in high income countries and as late as 5 years in low resource settings. This is after the optimal timeframe for applying interventions which could harness neuroplastic potential in the developing brain. Multiple barriers exist which affect clinicians’ confidence in diagnosing CP early. These range from the lack of definitive biomarkers to a lack of curative treatments for CP. Further barriers to diagnosis are proposed including; (a) difficulty finding a congruent fit with the definition of CP in an infant, where expected activity limitations might not yet be apparent; and (b) differences in the presentation of motor type and topography classifications between infants and children. These barriers may affect a clinicians’ confidence using “pattern recognition” in the differential diagnosis process. One of the central tenets of this paper is that diagnosis and classification are different, involving different instruments, and are more accurately conducted separately in infants, whereas they are fundamentally interconnected in older children and inform therapeutic decisions. Furthermore, we need to be careful not to delay early diagnosis because of the low reliability of early classification, but instead uncouple these two processes. Ongoing implementation of best practice for early detection requires creative solutions which might include universal screening for CP. Implementation and accompanying knowledge translation studies are underway to decrease the average age of diagnosis in CP.

“…Existing NHS programmes have been compared in a number of studies. These studies differed in the methods used, the countries or regions included, and the scope of the study (World Health Organization 2009;White 2011;Sloot et al 2015;Vos et al 2016;Kanji, Khoza-Shangase, and Moroe 2018). These studies identified common screening sequences used across existing NHS programmes.…”

Objectives: Newborn hearing screening (NHS) varies regarding number and type of tests, location, age, professionals and funding. We compared the provision of existing screening programmes. Design: A questionnaire containing nine domains: demography, administration, existing screening, coverage, tests, diagnosis, treatment, cost and adverse effects, was presented to hearing screening experts. Responses were verified. Clusters were identified based on number of screening steps and use of OAE or aABR, either for all infants or for well and high-risk infants (dual-protocol). Study sample: Fifty-two experts completed the questionnaire sufficiently: 40 European countries, Russia, Malawi, Rwanda, India and China. Results: It took considerable effort to find experts for all countries with sufficient time and knowledge. Data essential for evaluation are often not collected. Infants are first screened in maternity wards in most countries. Human development index and health expenditure were high among countries with dual protocols, three screening steps, including aABR, and low among countries without NHS and countries using OAE for all infants. Nationwide implementation of NHS took 6 years, on average. Conclusion: The extent and complexity of NHS programmes are primarily related to health expenditure and HDI. Data collection should be improved to facilitate comparison of NHS programmes across borders.

“…1,5 Infants with congenital head and facial abnormalities involving the earlobe, ear canal, and temporal bone anomalies, hyperbilirubinemia requiring an exchange of blood transfusion, use of ototoxic drugs, meningitis, premature birth (< 37 weeks), Appearance, Pulse, Grimace, Activity, Respiration (APGAR) index below four in the first minute and less than six in the first five minutes, use of mechanical ventilation for more than five days, and syndromes associated with hearing loss Pendred, Usher, Waardenburg, neurofibromatosis is an indication of hearing screening before the age of 6 months. [5][6][7] Sensory Neural Hearing Loss related to hypoxia in newborns is mainly related to Persistent Pulmonary Hypertension (PPHN) and Extracorporeal Membrane Oxygenation (ECMO) being risk factors for hearing loss in newborns. 8 Newborns with hyperbilirubinemia are known to cause specific changes in ABR waveforms, which disappear after returning to normal bilirubin levels through exchange transfusions.…”

“…Stage one screening is performed on infants aged 2-3 days, using TEOAEs by providing a stimulus in the form of sequential clicking sounds with a frequency range of 1,5-4,5 kiloHertz (kHz) and a wave intensity of 70 decibels (dB) Sound Pressure Level (SPL). 6,9,10,11 Results are divided into three categories, namely infants without hearing risk factors with bilateral pass responses considered to have normal hearing and excluded from further analysis, information about progressive genetic hearing loss remains given to families. Infants without risk factors with one or both sides refer responses are advised to take the TEOAEs test again one week after discharge.…”

Hearing loss in newborns is a serious matter, if it is not quickly diagnosed and starts early intervention, a child will experience social, speech, language, cognitive, and academic impairments. There is a method of hearing screening in newborns, which is divided into two types, universal newborn hearing screening, and targeted newborn screening. Both of these methods use OAEs and ABR as objective examination tools. The hearing screening method varies in each country, this difference is based on the test equipment used, age, frequency, professionals involved in screening, referral procedures, funding, and coverage areas. Indonesia uses two stages of screening, while Italy, America, Nigeria, France, India, and Poland use two to five stages of screening. Hearing screening of newborns using OAEs and ABR has a sensitivity of 100% and specificity of 99,3%.
