Cochlear implantation is a cost-effective solution for profound sensorineural hearing loss in South American children. This review highlights its clinical effectiveness and addresses challenges in providing this hearing rehabilitation in developing countries.
Area of Science:
- Otolaryngology
- Public Health
- Health Economics
Background:
- Profound sensorineural hearing loss in children presents significant challenges for hearing rehabilitation, particularly in developing nations.
- South America faces unique obstacles in providing effective cochlear implant care.
Purpose of the Study:
- To review and assess the effectiveness and cost-effectiveness of cochlear implantation for childhood profound sensorineural hearing loss in South America.
- To identify and discuss the challenges associated with cochlear implant programs in this region.
Main Methods:
- Systematic review of electronic databases, bibliographies, and references for published and unpublished studies.
- Sensitivity analysis to evaluate the impact of device cost, professional salaries, implant volume, and failure rates.
- Cost data collection from South American experts through estimations and known figures.
Main Results:
- Cochlear implantation demonstrated significant cost-effectiveness across all evaluated South American countries.
- Key challenges identified include high cochlear implant and deaf education costs, limited implant capacity, and the need for professional training.
- Despite data quality variations, the review confirms the clinical effectiveness and likely cost-effectiveness of unilateral cochlear implantation.
Conclusions:
- Unilateral cochlear implantation is a clinically effective intervention for childhood profound sensorineural hearing loss in South America.
- The procedure is likely to be cost-effective, offering a viable hearing rehabilitation strategy in developing countries.
- Addressing identified challenges is crucial for expanding access and improving outcomes.
