Study: $15 in return for each dollar invested in hearing care

The economic benefits of globally investing in hearing care interventions are huge, a study finds. Money invested will return manyfold.
Study: $15 in return for each dollar invested in hearing care

To address the growing prevalence of hearing loss, the WHO has identified a series of key evidence-based ear and hearing care interventions to be included within countries’ universal health coverage packages.

To assess the cost-effectiveness of these interventions and their budgetary effect for countries, a study has analysed the investment required to scale up services from baseline to the recommended levels and the return to society for every US$1 invested in the interventions.

$3.3 trillion in return

The study found that scaling up ear and hearing care interventions to 90% requires an overall global investment of US$238.8 billion over 10 years. Over a 10-year period, this investment promises substantial health gains with more than 130 million DALYs (Disability-Adjusted Life Years) averted.

These gains translate to a monetary value of more than US$1.3 trillion. In addition, investment in hearing care will result in productivity benefits of more than US$2 trillion at the global level by 2030. In total, the gains are US$3.3 trillion. Together, these benefits correspond to a return of nearly US$15 for every US$1 invested.

The WHO interventions

The proposed set of WHO interventions are:

  • Hearing screening and intervention for new-born babies and infants, pre-school and school-age children, older adults and adults at higher risk of hearing loss
  • Ear disease prevention and management
  • Access to technologies such as hearing aids, cochlear implants or hearing assistive technologies
  • Rehabilitation service provision

The study, "Global return on investment and cost-effectiveness of WHO’s HEAR interventions for hearing loss: a modelling study", was published in the Lancet.
