title: Children who could benefit from a cochlear implant: a European estimate of projected numbers, cost and relevant characteristics.
abstract: 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 pounds 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.
