Knowledge and attitude of parents/caregivers towards hearing loss and screening in newborns - a systematic review

Sociodemographic Factors Affecting Loss to Follow-Up After Newborn Hearing Screening: A Systematic Review and Meta-Analysis

OBJECTIVE

Universal newborn hearing screening (NBHS) has been widely implemented as a part of early hearing detection and intervention (EHDI) programs worldwide. Even with excellent provider knowledge and screening rates, many infants do not receive definitive hearing testing or intervention after initial screening. The objective of this study was to identify sociodemographic factors contributing to loss of follow-up.

DATA SOURCES

PubMed, Scopus, and CINAHL.

REVIEW METHODS

Per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the databases were searched from the date of inception through December 28, 2021. Studies containing sociodemographic information on patients who were referred to NBHS were included. Meta-analysis of odds ratios (ORs) was performed comparing rates of sociodemographic variables between patients adherent and nonadherent to follow-up.

RESULTS

A total of 169,238 infants from 19 studies were included. Low birth weight (OR 1.6 [95% confidence interval, CI 1.2-2.2, p < .001), racial minority (OR 1.4 [95% CI 1.2-1.6], p < .001), rural residence (OR 1.5 [95% CI 1.1-1.9], p = .005), lack of insurance (OR 1 [95% CI 1.4-2.5], p < .001), and public or state insurance (OR 1.7 [95% CI 1.2-4.2], p = .008) were associated with missed follow-up after referred NBHS. Associated maternal factors included low maternal education (OR 1.8 [95% CI 1.6-2.0], p < .001), young maternal age (OR 1.5 [95% CI 1.5-1.6], p < .001), unmarried maternal status (OR 1.5 [95% CI 1.1-1.9], p = .003), and current or former maternal smoking status (OR 1.8 [95% CI 1.4-2.2], p < .001).

CONCLUSION

Both infant and maternal sociodemographic factors influence follow-up compliance after referred NBHS. Focused efforts should be made by medical providers and policymakers to address these factors to ensure appropriate newborn hearing care and interventions are achieved.

Predictors of Parental Recall of Newborn Hearing Screening Program in Saudi Arabia

Hearing impairment is a prevalent disabling condition among children; all newborns should undergo a universal newborn hearing screening (UNHS). Unfortunately, many newborns who fail the screening test are lost to follow-up. Our study aims to evaluate parents' perceptions of UNHS and to identify predictors for newborn hearing screening recall in Saudi Arabia. A cross-sectional study involving Saudi parents with 0-to-18-year-old children born in Saudi Arabia was conducted. Descriptive statistics and binary logistic regression were used to describe the participants' characteristics and to identify UNHS recall predictors. A total of 1533 parents were surveyed. Overall, 29.9% of them recalled a hearing screening at birth, while 22.2% reported no hearing screening, and 47.8% were unable to remember. Only (6.9%) participants reported a failed hearing screening, of which 75.9% recalled a follow-up recommendation. Females, parents aged 30-34 years, consanguineous parents, and parents of newborns who were treated with antibiotics were more likely to recall hearing screening compared to others. This study highlights inadequate awareness of UNHS among parents. Our findings support the need to improve the reporting system of UNHS results and implement educational programs to increase parents' recall of hearing test results and ensure early follow-ups for neonates with failed test results.

Knowledge and attitudes of female caregivers in Samoa to childhood hearing loss and hearing services

OBJECTIVES

To assess the knowledge and attitudes of 150 female caregivers in Samoa to childhood hearing loss and hearing services, and to compare findings between urban (n = 100) and rural-dwelling (n = 50) caregivers.

METHODS

A semi-structured interview using a 26-item questionnaire was administered to participants in the Samoan language. Participants were required to respond "yes", "no", or "unsure".

RESULTS

Highest awareness of aetiology of childhood hearing loss was found for otitis media (88.7%), followed by noise exposure (64.7%) and family history (38%). Highest awareness of public health measures that may prevent/reduce otitis media was found for routine childhood immunizations (74.7%) and breast-feeding for first 6 months of life (69.3%). Overall, 40% of Samoan caregivers agreed that curses may cause childhood hearing loss. There was overwhelming support for community-based hearing services for newborns/infants (98%) and school students (97.3%).

CONCLUSIONS

There is positive support for community-based hearing health services for children among female caregivers of Samoa. There was high awareness of otitis media as a major cause of childhood hearing loss, as well as good knowledge of public health measures that reduce/minimise the risk of otitis media.

Prevalence of Hearing Impairment in High-Risk Neonates at Kalaburagi Region of Northern Karnataka: A Hospital-Based Cross-Sectional Study

The study estimated the prevalence of hearing impairment in high-risk neonates and effect of high-risk factors on the hearing. A hospital-based cross sectional study was conducted on 327 neonates with high-risk factors. All the high-risk babies were screened using TEOAE and AABR followed by diagnostic ABR testing. Six (2%) of high-risk neonates were found to have bilateral severe sensorineural hearing loss. Risk factors associated with hearing impairment include multiple risk factors of Preterm delivery, hyperbilirubinemia, congenital anomalies, neonatal sepsis, viral or bacterial infection, positive family history of hearing loss and prolonged NICU stay. Further, the inclusion of AABR along with TEOAE has been shown to be a useful tool in reducing false-positive rates and identifying hearing loss.

Universal Newborn Hearing Screening: An Indian Experience of Conceptualizing and Testing a Comprehensive Model

There have been isolated attempts to implement newborn hearing screening at various setups across India. However, none of these attempts has followed a holistic model comprising of multiple components. Therefore, a need was felt to design and implement a comprehensive universal newborn hearing-screening model to, improve follow-up, and provide practically implementable solutions for developing economies. The model was conceptualized after a detailed preliminary planning level. Separate protocols for newborns from well-baby nursery and neonatal intensive care unit were implemented. Measures were implemented to improve follow-up. Knowledge, attitude, and practices survey followed by a sensitization program was carried out to highlight the importance of newborn hearing screening among the healthcare providers. A knowledge and attitude survey was also carried out among mothers. The estimated prevalence rate was 8.78 per 1000. Measures enabled an improved follow-up rate that lead to a reduced age of identification to 6 months. The surveys among mothers and healthcare providers helped to identify the lacunae in knowledge levels, which need to be filled in order to improve their attitudes. Thus, this was a successful model for universal newborn hearing screening comprising of two-stage screening, separate protocols, steps to improve follow-up, improving awareness among parents, sensitization programs, and surveys among mothers as well as healthcare providers.

Effectiveness of Neonatal Hearing Screening System: A 12-Year Single Centre Study in the Czech Republic

PURPOSE

The study aims to evaluate the number of examined newborns and the results of screening for twelve years (2008-2019) and to assess the effectiveness of the established system of neonatal hearing screening.

DESIGN AND METHODS

The study was designed as a retrospective longitudinal data analysis. The data included all the children (19,043) born in the hospital and also children (74) transferred from other healthcare facilities. A total of 19,117 children were included in the research group.

RESULTS

In the first three years, a higher number of children did not pass the hearing screening, which was followed by a declining trend in the following years. After the first year of screening (2008), there was an improvement in diagnosis linked with a decrease in false-positive screening results (from 9.4% to 6.4%; p = 0.002). From 2008 to 2015, the ratio of children with positive screening to those with negative screening had a steady or declining trend.

CONCLUSIONS

The results showed a reduction in false-positive results after the first year of the screening program, probably due to improved care management and a gradual increase in the skills of the nurses performing the screening.

PRACTICE IMPLICATIONS

The cornerstones of neonatal hearing screening are a sufficient number of trained neonatology nurses, their mutual substitutability and the availability of a hearing screening device in the newborn ward every day. The results imply the importance of periodic evaluation of the obtained data, enabling early detection of possible deficiencies in the hearing screening system.

Emerging Data from a Newborn Hearing Screening Program in Sharjah, United Arab Emirates

Objectives

Newborn hearing screening (NHS) plays a critical role in early identification of hearing loss and subsequent early habilitation. Active parental involvement influences the success of NHS, particularly the initial NHS and follow-up. The current study reports the results of an NHS program in a cohort of babies born in a tertiary care hospital in Sharjah, United Arab Emirates (UAE). Further, it explores a two-stage NHS model to reduce false responses, thereby alleviating parental anxiety.

Methods

Retrospective observational study was conducted for a period of five years from January 2017 to December 2020. NHS was done as a two-stage model. All the healthy newborn babies were screened using Automated Auditory Brainstem Response (AABR) by trained audiology professionals. Babies who failed the first NHS were followed up after two weeks. Further, babies that failed the follow-up NHS were sent for diagnostic hearing evaluation and intervention as necessary.

Results

A total of 1821 newborn babies were screened during the study period. Eighty-one percent of babies passed the initial NHS. Four hundred and twenty-three (23.22%) babies were referred on the first NHS and were followed up after 2 weeks. Among these babies, 7.03% (24) failed second NHS. Nine (37.50%) of the 24 babies were confirmed to have hearing loss in both ears. The incidence of hearing loss in our cohort was 4.94 per 1000. Confirmed hearing loss was statistically higher in boys than girls (p < 0.05).

Conclusion

Current study was an attempt to report the emerging NHS data as part of the implementation of an NHS program. The study findings emphasize the need for a two-stage model of NHS to rule out false responses.

The role of health promotion in the development of ear and hearing health services in the Pacific Islands : A literature review

The Pacific Islands have among the highest rates of ear disease and hearing loss in the world. Ear and hearing health services are limited in this region; however, a significant proportion of avoidable hearing loss and disability may be addressed through public health promotion activities. In order to develop appropriate hearing health education campaigns and promotion initiatives, knowledge and attitude studies among target population groups are vital. This review aimed to summarize the research literature on knowledge and attitude to ear disease and hearing loss in the Pacific Islands in order to develop appropriate health promotion campaigns for our context in Samoa. PubMed and ScienceDirect databases were searched for relevant journal articles. Key search terms were ‘Pacific Islands’, ‘ear disease’, ‘hearing loss’, ‘knowledge’, ‘attitudes’, and their relevant synonyms. There was no limit on the date of publication. Only one journal article met the review criteria. Parental knowledge and attitude to childhood hearing loss and hearing services in the Solomon Islands was overwhelmingly positive (96%–99.3%). There was high parental awareness of ear disease as a cause of hearing loss among children (94%) and high parental awareness of public health initiatives aimed at reducing ear disease and hearing loss such as routine childhood immunizations (84%) and breastfeeding (76%). Knowledge and attitude studies among key stakeholders are needed to develop appropriate health promotion activities to reduce the preventable causes of hearing loss in the Pacific Islands. Health promotion activities should prioritize major public health issues of ear disease and noise-induced hearing loss.

Parents' satisfaction with a trial of a newborn hearing screening programme in Jordan

OBJECTIVE

This study examines parents' satisfaction level toward a trial of a newborn hearing screening programme (NHSP) that was applied in King Abdullah II University Hospital (KAUH) in Jordan over one year. This is the first study that investigated parents' satisfaction toward a hearing screening programme in the Arab countries, and the results will improve any future screening programmes in the Arabian region.

METHOD

The main tool for this study was a questionnaire that was translated and modified from the original version of the Parental Satisfaction with the Newborn Hearing Screening Programme (PSQ-NHSPs1). The questionnaire consisted of 19 items covering five main aspects of the NHSP. The parents' responses were not anonymously given where the parents whose children had undergone the hearing screening were contacted by phone using the data record of the hospital.

RESULTS

The majority of the parents were very satisfied with the programme overall and showed great support and appreciation for the effort in testing their babies and increasing their awareness. The satisfaction levels varied among the specific aspects of the programme. Good portion of the parents did not receive the brochure containing information about the screening, and almost half of them did not know the results of the hearing screening.

CONCLUSION

Parents were overall satisfied with neonatal hearing screening programme that was conducted at KAUH. However, parents were less satisfied with information related to the test procedure and results. Parents' responses in this study could be used to improve any future hearing screening program in Jordan or in the Arab countries.

Who misses the newborn hearing screening? Five years' experience in Friuli-Venezia Giulia Region (Italy)

INTRODUCTION

Permanent hearing impairment is the most common sensory disorder in newborns. The Universal Newborn Hearing Screening (UNHS) is widely adopted as a cost-effective procedure to achieve early identification and treatment of congenital hearing impairment, with the final goal of an improved linguistic and cognitive outcome for hearing impaired children. The Italian Ministry of Health has recently comprised UNHS in the Essential Level of Health Assistance. Nevertheless, programs still vary both across and within Italian Regions in terms of coverage, testing, referral and tracking protocols. In Friuli-Venezia Giulia region the program for the early identification of newborn and childhood hearing impairment is operative since 2012. In order to minimize the lost to follow-up cases, UNHS and childhood hearing surveillance activities have been organized in close collaboration among birth centres, paediatric audiology services, territorial Family Paediatricians and the sole regional centre for paediatric hearing loss management.

MATERIAL AND METHODS

We performed a five years' retrospective analysis of the UNHS experience in Friuli-Venezia Giulia comparing the UNHS activity of year 2013 and year 2017. The focus of the study concerns the "missing" cases. Three different typologies of "miss" cases ("documentation-miss", "access-miss" and "pathway-miss") have been defined in correspondence with main reasons for their occurrence.

RESULTS

Births in Friuli-Venezia Giulia were 9465 and 8432, respectively in 2013 and 2017. International quality indicators improved with a gain of efficiency in 5 years' experience. However, "missing" cases were 486 in 2013 and 321 in 2017, mainly due to the lack of an efficient documentation system.

CONCLUSION

UNHS programs have proven to be valuable and cost-effective in Friuli-Venezia Giulia and other Italian regions. New resources and efforts are required to achieve a complete standardization and informatisation of the UNHS data to avoid documentation gaps. A possible strategy would point to the opportunity to unify data management systems for all the ongoing newborn screening programs (metabolic, hearing and visual), linking the integrated IT system with the regional repository of current datasets.

Mapping the content of mothers' knowledge, attitude and practice towards universal newborn hearing screening for development of a KAP survey tool

Understanding mother’s knowledge, attitude and practice (KAP) of permanent childhood hearing impairment (PCHI) is essential for the success of universal newborn hearing screening (UNHS) as poor compliance and follow-up remains a global challenge. To determine content area for a questionnaire that measures PCHI-related KAP in rural mothers, we trained moderators who interviewed 145 pregnant women (17 groups) from 5 ante-natal clinics. Interviews were recorded, transcribed, summarised and analysed using thematic framework analysis. Four knowledge themes were identified: 1) PCHI was perceived as the malfunction of hearing leading to disability; 2) a poorly-responsive/communicative child may have PCHI; 3) lifestyle, hereditary and environmental factors are significant causes of PCHI; 4) medical management of PCHI was doubted, with some advocating birth and ancestral rituals. Two themes were identified for attitude: 1) beliefs that PCHI was emotionalised due to the negative lifelong impact on the child and family; 2) UNHS processes were favourable though some preferred other belief systems. Three themes were identified for practice: 1) doctors were the first choice followed by traditional healers; 2) willingness to continue follow-up although challenges exist; 3) minimal family support during consultation. The contextualised KAP of women regarding UNHS processes and PCHI provided content area for the design of a KAP tool.

Systematic review of knowledge of, attitudes towards, and practices for newborn hearing screening among healthcare professionals

INTRODUCTION

The success of newborn hearing screening programs lies in the timely identification, diagnosis, and management of children with hearing loss accomplished via a multidisciplinary newborn hearing screening (NHS) team. The team is typically comprised of various healthcare professionals who act as decision makers as well as facilitators for different stages in the screening process. Team members' knowledge of, attitudes towards, and practices for early hearing detection and intervention programs are critical for success and prevention of loss to follow up. In this context, it becomes crucial to understand their knowledge of, attitudes towards, and practices for towards newborn hearing screening.

METHODS

A systematic review was conducted on the following databases; PubMed/Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, Web of Science, Science Direct and Cochrane Library. This search was carried out using various keywords such as practitioners, newborn hearing screening, knowledge, attitudes, and practices in different combinations. The review was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-analyses statement guidelines.

RESULTS

A total of 271 hits were obtained of which 20 articles were found suitable for inclusion in the final review. Overall, similar results were found regarding team members' knowledge of NHS programs, regardless of country of origin. Similarly, attitudes toward NHS programs were positive. Team members' experiences with NHS programs varied from country-to-country and across healthcare professionals. Results consistently showed gaps in team members' knowledge suggesting the need for outreach and professional education programs on NHS.

CONCLUSION

NHS teams members from different countries, healthcare systems, and early hearing detection and intervention programs show gaps in critical knowledge warranting outreach and educational programs.

Knowledge and attitude of mothers regarding infant hearing loss in Changsha, Hunan province, China

OBJECTIVE

The objective of this study was to explore the knowledge and attitude among mothers of newborns regarding infant hearing loss (HL) in Changsha, Hunan province, China.

DESIGN

A questionnaire including 18 items was given to mothers.

STUDY SAMPLE

A total of 115 mothers participated in the study.

RESULTS

Seven risk factors for hearing loss were identified correctly by above 60% of respondents and the top three were prolonged noise (88.7%), high fever (82.6%) and ear discharge (82.6%). Poor knowledge was demonstrated on risk factors jaundice (20.0%), measles (22.6%), convulsion (33.0%) and traditional Chinese medicine (39.1%). Maternal knowledge scores in identification and intervention (2.68 ± 0.31) was slightly higher than the score in risk factors (2.47 ± 0.34). Ninety-nine per cent of the mothers expressed the willingness to test baby's hearing soon after birth and concern about hearing.

CONCLUSIONS

Mothers were concerned about baby's hearing and the attitude was positive. However, the correct recognition rate towards some risk factors for HL was low. Action needs to be taken to raise awareness about ear and hearing care, prevent HL caused by preventable causes and prompt early identification, early diagnosis and intervention of HL.
