Or contact Direct Mail Works (see contact details above) by email, post, fax or phone. HTA on CD is currently free of charge worldwide.The website also provides information about the HTA programme and lists the membership of the various committees. Objectives: To investigate whether it is clinically effective and cost-effective to provide (i) a unilateral cochlear implant for severely to profoundly deaf people (using or not using hearing aids), and (ii) a bilateral cochlear implant for severely to profoundly deaf people with a single cochlear implant (unilateral or unilateral plus hearing aid). . Quality of life measured with generic and disease-specific instruments or by interview mostly showed significant gains or positive trends from using cochlear implants. The Markov model base-case analysis estimated that, for prelingually profoundly deaf children, the incremental cost-effectiveness ratio (ICER) for unilateral implantation compared with no implantation was £13,413 per quality-adjusted life-year (QALY). Assuming the utility gain for bilateral implantation is the same for adults and children, the ICERs for simultaneous and sequential bilateral implantation versus unilateral implantation were £40,410 and £54,098 per QALY respectively. For postlingually sensorineurally profoundly deaf adults, the corresponding ICERs were £14,163, £49,559 ...

Searching for a talking face: The effect of degrading the auditory signal.

“…A cochlear implant is an electronic device which restores partial hearing to people who are profoundly deaf. By stimulating the auditory nerve directly via an electrode array which has been surgically implanted into the inner ear (the cochlea), cochlear implantation restores the audibility of sounds (Bond et al, 2009). However, the signals that implantees receive are degraded spectrally (they receive fewer channel of information) and temporally (limited to slow fluctuations in amplitude over time).…”

Análisis de Beneficio de Incidencia: Implante coclear infantil en el Hospital Barros Luco Trudeau período 2003 a 2011

“…Si bien existen diversos estudios que reconocen la efectividad y la costo efectividad del implante coclear precoz en niños con hipoacusia sensorioneural severa y profunda [7][8][9][10] , un alto porcentaje de esta población infantil no accede a esta intervención, tanto por cobertura insuficiente en los servicios sanitarios [11][12][13] como por factores económicos y étnicos de exclusión social [13][14][15][16] .…”

Rapid Assessment of Bilateral Cochlear Implantation for Children in Kazakhstan

“…Of the remaining 37 abstracts, 32 were unrelated to comparison of bilateral and unilateral CI in children, or did not consider clinical effectiveness. Two HTA publications (4,5) and three systematic reviews that included comparison of bilateral and unilateral CI in children (6 -8) were used for the HTA report. No relevant high quality primary studies were found that had been published subsequent to material included in the reviews..…”
