QUALITY STANDARDS OF QUALITY STANDARDS OF SCREENING PROTOCOLSSCREENING PROTOCOLS
• Quality standards are still lacking for
the various screening protocols.
• Only very few screening devices have been clinically validated in large scale trials aimed at evaluating the performances of the new automatic algorithms.
FUTURE RESEARCHFUTURE RESEARCH
• optimize screening technologies
• screening criteria for well- and at-risk babies
• strategies/technologies for early assessment (particularly methods for diagnostic ABR)
• strategies for early fitting
• criteria for implantation in very young infants (how young? bilateral? Brainstem?)
FUTURE OF EHDI SYSTEMS IN THE FUTURE OF EHDI SYSTEMS IN THE EUEU
• Successful implementation of EHDI systems will crucially depend on availability of a new generation of professionals
• This is not surprising because EHDI systems were an undemanded need (Adrian Davis)
