Early identification and intervention of hearing loss in children is critical for their academic and social development. A recent study titled Cost-effectiveness analysis of hearing screening program for primary school children in southern Iran, Shiraz provides compelling data on the benefits and cost-effectiveness of universal hearing screening programs.
Conducted over six years, the study screened an average of 22,853 children annually, identifying 260 true positive cases of hearing loss each year. The cost of screening per child was estimated at $30.32 Purchasing Power Parity (PPP), while the cost of not screening was $13.75 PPP per child. The study also calculated an averted Disability-Adjusted Life Year (DALY) of 7 years per child due to early intervention.
Key findings from the study include:
- Average annual true positive identification rate: 1.1% (260 out of 22,853 children)
- Cost of hearing screening per child: $30.32 PPP
- Cost of not screening per child: $13.75 PPP
- Averted DALY due to screening: 7 years per child
The study utilized a decision tree model to compare the costs and effectiveness of conducting versus not conducting hearing screenings. Despite higher initial costs, the screening strategy proved to be more cost-effective in the long run, with an Incremental Cost-Effectiveness Ratio (ICER) of $0.06 PPP per identified case and $2.37 PPP per averted DALY.
For practitioners, these findings underscore the importance of implementing universal hearing screening programs. Early identification allows for timely interventions, which are crucial for speech and language development, academic success, and overall quality of life. Additionally, the cost savings from reduced special education needs and improved social outcomes further justify the investment in such programs.
Encouraging further research in this area can help refine screening methods and improve the accuracy and efficiency of these programs. Practitioners are urged to advocate for and participate in research initiatives that explore the long-term benefits and potential improvements in hearing screening protocols.
