Quality of evidence of assistive technology interventions for people with disability: An overview of systematic reviews

摘要

This overview summarizes the available evidence from systematic reviews of outcomes studies on various assistiventechnologies (AT) for persons with disabilities. Systematic reviews published between January 2000 and April 2010 werenidentified by comprehensive literature searches. Study selection, data extraction and methodological quality evaluation were donenby two authors independently. The quality of evidence was summarized by explicit methods. Types of disabilities, settings, andnAT interventions were recorded. Outcomes were mapped according to the Taxonomy of Assistive Technology Device Outcomes.nForty-four systematic reviews were included in this overview. High-quality evidence was found in single AT (positive effectsnof providing AT in connection with home assessment and hearing aids, no effects of hip protectors) for limited populationsn(older people at home, people with hearing loss, and older people in institutional care, respectively). Low-quality or unclearnevidence was found for the effectiveness of the other evaluated AT interventions. Current gaps in AT outcomes research werenidentified. Many frequently used devices have not been systematically reviewed. Well-designed outcomes research to informnclinical decision-making is urgently needed. The systematic review methodology seems to be feasible for summarising ATnoutcomes research, but methodological development for grading and for primary studies is warranted
