Parental perceptions to new-born screening for hearing loss in Nigeria: A systematic review.

OBJECTIVE: To investigate the perceptions of parents towards universal new-born screening for hearing loss in Nigeria.

METHODS: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system. A comprehensive search was undertaken using multiple databases (National Library of Medicine, PubMed, Cochrane Library, Scopus, Google Scholar, and MEDLINE) published in English between 2009 and 2018. The sample size of 10 studies were retrieved by using a predefined inclusion and exclusion criteria, keywords, and Boolean operator search patterns. Data extraction and analysis and quality appraisal of the selected articles was carried out.

RESULTS: 80% of the identified studies indicated negative perceptions of Nigerian parents towards new-born hearing loss screening programmes. Possible reasons behind such negative perceptions were categorised into demographic factors, psychological factors, behavioural factors, and service-related factors. Specifically, barriers included low income, misconceptions, mode of delivery, fear of associated risk with screening procedure, preference for traditional medicines, inappropriately designed screening programmes, cost of screening programmes, resource-limited settings, lack of awareness about risk factors and their effects.

CONCLUSION: The research concluded that it is necessary to focus on the range of underlying factors (including awareness and education) contributing in shaping the above mentioned negative perceptions among Nigerian parents. The findings have great implications for the theoretical researchers for developing future research path as well as practical suggestion for authorities in policymaking in the healthcare sector in Nigeria.
