The incidence of profound hearing impairment by the age of 5, derived from a number of retrospective studies in the UK (population about 58 million ; birth rate 14/1000), is estimated to be about 300 per annual birth cohort in the 1990s.
This estimate includes 80 children who might be expected to acquire deafness in those first 5 years.
Projected to Europe as a whole (population 511 million ; birth rate 12/1000) this would mean a population who should be considered as potential cochlear implant patients of some 2268 children, given a variety of assumptions.
At a take-up rate of 25% for both congenital and acquired cases of profound hearing impairment this would imply a European-wide expenditure of the order of £17 m/p.a. on hardware and associated rehabilitation programmes.
The need for such programmes is explored, in the context of strategies of early identification of hearing impairments.
