Cochlear implants and deafness: a global case study to increase policy awareness and action on an under-resourced health issue.

There has been a major growth in global health networks in recent decades to address health issues including tobacco use, alcohol abuse, and maternal mortality. Most conditions that incur high costs have provoked networks of advocates working to mitigate the impact, increase investment in research, and establish campaigns. Global health networks often work simultaneously across policy, knowledge creation, and advocacy. Until recently there has been limited activity in global health networks and advocacy addressing hearing loss and deafness which has contributed to its relatively low visibility with policymakers compared to other health conditions. This discussion paper reports on a global consultation that explored the views of advocacy groups and individuals on advocacy for the management of hearing loss, and cochlear implantation (CI). It focussed on stakeholders' views of current advocacy endeavours, opportunities and barriers, and the possible development of a global advocacy network to improve access to cochlear implantation and the supporting services. The subsequent development of a global health network, the Cochlear Implant International Community of Action (CIICA) is discussed and the conditions necessary for the successful development of health networks are explored. This paper will be of interest to those wishing to understand the factors influencing the development of health networks and advocacy.
