Inter-regional Newborn Hearing Screening via Telehealth in Ghana

Abstract

Background: Newborn hearing screening is a vital aspect of the Early Hearing Detection and Intervention program, aimed at detecting hearing loss in children for prompt treatment. In Ghana, this kind of pediatric hearing service is available at only one health care facility located in the Greater Accra Region. The current practice in effect has virtually cut-off infants in the other regions from accessing hearing screening and other pediatric audiological services. This has prompted a study into alternative methodologies to expand the reach of such services in Ghana. The present study was designed to assess the feasibility of using telehealth to deliver newborn hearing screening across Ghana. Purpose: To assess the feasibility of using telehealth to extend newborn hearing screening services across the ten regions of Ghana. Research Design: A correlational study was designed to determine the extent of association between test results of telehealth and the conventional on-site methods (COMs) for conducting newborn hearing screening. The design also allowed for testing duration between the two methods to be compared. Study Sample: Fifty infants from the Brong-Ahafo Regional Hospital (BARH) were enrolled. The infants aged between 2 and 90 days were selected through convenience sampling. There were 30 males and 20 females. Procedure: Newborn hearing screening using distortion product otoacoustic emissions were performed via telehealth. By adopting the synchronous telehealth model, an audiologist located at the Korle-Bu Teaching Hospital conducted real-time hearing screening tests over the internet on infants who were at the BARH. The former and latter hospitals are located in the Greater Accra and the Brong-Ahafo Regions, respectively. As a control, similar hearing screening tests were conducted on the same infants at BARH using the conventional face-to-face on-site hearing screening method. Data Collection and Analysis: The test results and testing duration of the telehealth method and the conventional on-site approach were compared and subjected to statistical analysis. Here, the Spearman?s correlation coefficient (r s) was used to determine the level of correlation between the test results, whereas the paired t-test statistic was used to test the level of significance between the testing duration of the two methods. Results: Analysis of the test results showed a significantly high positive correlation between the telehealth and the COMs (r s = 0.778, 0.878, 0.857, 0.823, p < 0.05 @ 2.0, 3.0, 4.0, and 5.0 kHz respectively). Also, the difference in testing duration of the two methods was not statistically significant [t (99) = 1.309, p > 0.05]. The mean testing duration (in seconds) of telehealth was 27.287 (standard deviation = 27.373) and that of the COM was 24.689 (standard deviation = 27.169). Conclusion: The study showed the feasibility of establishing an interregional network of newborn hearing screening services across Ghana using telehealth. It is more efficient to deploy telehealth for...

Can SARS-CoV-2 positive pregnant women affect the hearing of their newborns: A systematic review

“…Over the last decade, Tele-audiology (including remote HL) has grown significantly as the technological landscape has altered [43] . Ameyaw et al reported that using distortion product otoacoustic emissions to screen newborn hearing over the Internet was comparable to the traditional face-to-face on-site HS approach [44] . The ongoing omicron pandemic has had a tremendous impact on society because of its incredible spread and intrinsic severity [45] .…”

Evidence-Based Implementation of the Family-Centered Model and the Use of Tele-Intervention in Early Childhood Services: A Systematic Review

“…Both the study by du Plessis et al and Ameyaw et al [ 52 , 67 ] focused on the detection and diagnosis of deafness or hearing loss. The first study involved the establishment of an interregional network with the ultimate aim of conducting a comparative analysis between two hearing screening techniques, carrying it out remotely and face to face.…”

“…Along the same lines, studies more focused on early detection have implemented this technology to collect information based on developmental milestones or standard values of typical development. Thus, in the case of detecting any kind of deviation, this entails notifying the primary caregiver [ 50 , 53 , 67 ] and suggesting that they request an appointment with their referral center [ 50 , 53 ], enabling them to address it early.…”

Tele-Audiology: Current State and Future Directions

“…Monica et al ( 57 ) conducted remote synchronous audiometric and DPOAE screenings in school-aged children ( n = 31) in India using teachers as facilitators and found results similar to traditional, in-person testing. Ameyaw et al ( 58 ) examined remote synchronous DPOAE screenings in a group of newborn infants ( n = 50) in Ghana. Screenings were completed in-person and remotely by an audiologist via the internet with real-time audio, video, and text messaging between the facilitator and audiologist.…”
