Ear and Hearing: December 2007 - Volume 28 - Issue 6 - p 773-777 doi: 10.1097/AUD.0b013e318157f06c Buy Metrics AbstractIn Brief This is the final article in a series of five review articles and one editorial that summarizes the proceedings of the National Institute on Deafness and Other Communication Disorders workshop on Outcomes Research in Children with Hearing Loss held December 12 and 13, 2006. The purpose of this article is to highlight the recommendations that emerged during the workshop, addressing the developmental needs of children with hearing impairment. The information in this summary is based on the National Institute on Deafness and Other Communication Disorders workshop minutes available at http://www.nidcd.nih.gov/funding/programs/hb/outcomes/recommendations.htm. General research issues focus on funding mechanisms, access to a sufficient population, experimental cohorts and control groups, research methods and outcomes, standardization of testing across agencies and intervention programs, and facilitating access to data. Discussion of those issues is followed by an outline that presents future needs in outcomes research, including research design, sources of variance, research needs and gaps, and development of measurement tools. This final review summarizes the recommendations of the NIH-NIDCD Workshop identifying and prioritizing the developmental needs of children with mild to severe sensorineural hearing impairment. The information in this summary is based on the NIDCD Workshop minutes available at http://www.nidcd.nih.gov/funding/programs/hb/outcomes/recommendations.htm. An outline draws attention to future research needs and gaps in outcomes research, particularly in terms of research design, sources of variance, and development of measurement tools. Some recommendations emphasize the importance of studies that quantify outcomes in this understudied population through prospective, longitudinal research. © 2007 Lippincott Williams & Wilkins, Inc.
