Recent years have
seen significant advances in the technological content and flexibility
of amplification devices and these developments pose new challenges for
clinical practice. Matching technical solutions to the needs of hearing
impaired listeners requires an understanding of the many dimensions of
candidature, including impaired psychoacoustic function, listening demands
of different auditory lifestyles, and non-auditory aspects such as expectation,
motivation, psychology and cognitive function. As the available options
expand, an increasing emphasis is evident on measures of outcome with
proof of validity, reliability and clinical utility. This presentation
documents the ways in which the technological content and rehabilitative
context of services for hearing impaired people can be used to substantially
alleviate disability and handicap. Where resources are not sufficiently
elastic to allow unfettered access to unlimited technology and rehabilitation,
a targeted candidature regime is advocated (as an alternative to simple
rationing or universal low cost, low effectiveness provision). This presentation
takes examples from the current status of resources (hardware and rehabilitative)
within the United Kingdom National Health Service and demonstrates, at
individual and group levels, the ways in which a set of routinely available
outcome measures can be used to assess the clinical effectiveness and
cost effectiveness of protocols to match management options to the needs
of listeners, and to optimise those protocols. It is argued that the set
of general principles of using outcome measures to maximise clinical effectiveness
and cost effectiveness are of general applicability. |
