Cost and outcome of a community-based paediatric hearing screening programme in rural India with application of tele-audiology for follow-up diagnostic hearing assessment

Objective: This study evaluated the cost and outcome of a community-based hearing screening programme in which village health workers (VHWs) screened children in their homes using a two-step DPOAE screening protocol. Children referred in a second screening underwent tele diagnostic ABR testing in a mobile tele-van using satellite connectivity or at local centre using broadband internet at the rural location. Design: Economic analysis was carried out to estimate cost incurred and outcome achieved for hearing screening, follow-up diagnostic assessment and identification of hearing loss. Two-way sensitivity analysis determined the most beneficial cost-outcome. Study sample: 1335 children under 5years of age underwent screening by VHWs. Results: Nineteen of the 22 children referred completed the tele diagnostic evaluation. Five children were identified with hearing loss. The cost-outcomes were better when using broadband internet for tele-diagnostics. The use of least expensive human resources and equipment yielded the lowest cost per child screened (Rs.1526; $23; Euro21). When follow-up expenses were thus maximised, the cost per child was reduced considerably for diagnostic hearing assessment (Rs.102,065; $1532; Euro1368) and for the cost per child identified (Rs.388,237; $5826; Euro5204). Conclusion: Settings with constrained resources can benefit from a community-based programme integrated with tele diagnostics.
