The first step in the hearing aid fitting and selection process is to determine the patient's hearing disability, motivation, lifestyle, finances, and cosmetic concerns. Most hearing impairments can be helped with a modern hearing aid. With a symmetric hearing loss, a binaural fitting provides the most benefit and should be attempted initially. The binaural fitting may not be successful in cases with large asymmetries in auditory function. The advances in electronic technology, such as the digital hearing aid, are moving faster than the research to determine which is the most effective signal processing method. The near future should yield more significant improvements in hearing aids that will provide a better quality of life of the hearing-impaired population.
The conceptual basis for intermediate outcomes has been established, and scientifically sound methods are available for assessment of these short-term outcomes. While modest intermediate outcomes research experience assessing imaging technology has accumulated in the literature, much more remains to be done, for the benefit of both patients and physicians. I would recommend that intermediate outcomes research become more focused on assessment earlier in the diffusion phase of imaging technology development. These studies should be based on traditional diagnostic accuracy studies, but these should be extended to include well-designed, high scientific quality treatment impact studies. Furthermore, such studies need to be multidisciplinary and multiinstitutional/multisite and include patient utility assessment components.
