Abstract
Aim. To determine the feasibility of implementing a universal newborn hearing screening programme at National Women's Hospital (NWH), Auckland, New Zealand. Method. This feasibility study evaluates the potential for success of a Universal Newborn Hearing Screening (UNHS) Programme in a tertiary hospital setting. A review of the present provision of care for infants with congenital hearing loss and a clear description of the current environment and resources at National Women's Hospital was undertaken. By utilising the four key determinants of a feasibility study as described by Whitten, Bently & Dittman (2001) I was able to provide a clear description of the current position and explore the alternative solutions, ensuring an accurate and comprehensive study approach was undertaken. Results. A detailed analysis of the environmental setting and population at NWH identified the support required for implementing a UNHS programme. Findings also identified the acceptance by both staff and consumers in providing improved congenital hearing loss detection and intervention early in the newborn period. The evidence supported recommendations for two possible hearing screening protocols that are both practical and feasible in the National Women's Hospital setting for the detection of congenital hearing loss in the newborn population. Conclusion. Overall findings indicated that the implementation of UNHS at National Women's Hospital is feasible. The current method of detecting hearing loss in the newborn population is inadequate with unacceptable delays for diagnosis and appropriate intervention to improve outcomes for those identified with a congenital hearing loss. The protocols supported by this study are based on the research findings and are unique to the NWH environment and target population. They will ensure the infants with congenital hearing loss are detected and referred early (soon after birth) so formal audiological diagnosis and strategies for intervention can occur with treatment implemented by six months of age. This will improve the child's communication and learning skills, improving their level of education and long term learning ability. Further and regular audit of the programme, screeners and outcomes will be required to ensure its efficiency as a screening service for congenital hearing loss.
