Although increasing effort is being devoted to developing strategies to increase knowledge transfer and the uptake of health technology assessment (HTA) by various stakeholders, very little is known about the utilization and dissemination of HTA findings by patient and consumer organizations. The goal of this study is to understand how and why patient and consumer organizations use HTA findings within their organizations, and what factors influence how and when they communicate their findings to members or other organizations.
We examined the use and dissemination of four controversial HTA reports by sixteen patient and consumer organizations in Ontario and Quebec. We gathered data from semistructured interviews conducted between December 2006 and April 2007.
Although HTA findings are often used by the patient and consumer organizations, key differences were observed in exactly how the four HTA reports were used. Three types of use (instrumental, conceptual, and symbolic) are reported and illustrated. We highlight the importance of the organization's mission and knowledge base in explaining the types of use observed.
We contend that the use and dissemination of HTA reports by specific groups could help in widening the debate around controversial health technologies. The implications and opportunities for HTA agencies relate to the following: (i) identification of "lay" organizations that could help in disseminating results; (ii) acknowledgement of a "lay" audience for HTA findings; (iii) strategic inclusion of advocacy groups during the assessment process for highly controversial technologies; and (iv) contribution of these organizations to the push efforts of knowledge transfer.
"Finally, some definitions limit dissemination to specific audiences, such as individuals in clinical settings (Cronenwett, 1995; Montgomery et al., 2001), end-users who have the capacity to utilize the knowledge in their practice (Knott & Wildavsky, 1980; Scott et al., 2007; Wilson et al., 2010), or to an audience that the researchers want to influence (IHE, 2008). Other authors remain more general and rather suggest that the message be tailored to the specific audience targeted, notwithstanding if this audience relates to a clinical, research, community, or government setting (Brachaniec et al., 2009; Fattal & Lehoux, 2008; Kahn, 2009; Kobus et al., 2007; Lomas, 1993; Tetroe et al., 2008; Wilson et al., 2010). Given that the definitions of knowledge dissemination published in the literature vary significantly and seem to be influenced by the " object " to be disseminated, and given the purpose of the project at stake, which will be further described in the next section, knowledge dissemination is defined in this article as an active intervention that aims at communicating research data to a target audience via determined channels , using planned strategies for the purpose of creating a positive impact on the acquisition of knowledge, attitudes, and practice.

[Show abstract][Hide abstract] ABSTRACT: This literature review seeks to examine knowledge dissemination interventions (KDIs) implemented in health research and gauge their effectiveness on three kinds of outcomes: (a) knowledge acquisition, (b) changes in attitudes, and (c) changes in practice. MEDLINE and Cumulative Index to Nursing and Allied Health Literature databases from 2006 to 2011 were searched. Nineteen articles were retrieved. Most of the KDIs that were evaluated had a positive impact on knowledge acquisition and changes in attitudes, but a limited one on practice. KDIs are diverse in terms of knowledge, actors, contexts, and dissemination methods. They cannot be readily applicable to other projects.

[Show abstract][Hide abstract] ABSTRACT: Liquid Crystal on Silicon (LCoS) microdisplays is a viable technology for applications in projection and near-to-eye displays. As the performance of the microdisplay is related to the image quality, the characterization and understanding of the critical factors affecting the image quality need to be studied. The overall objective of this work is to establish a quantitative understanding of the functional performance of the tiled LCoS microdisplay as a function of thermal gradients and mechanical stress. The initial design calls for a three-tile configuration. Such a device needs to be assembled to very exacting tolerances, and must be able to undergo all of the assembly, and operating conditions without significant changes in the critical parameters, namely tile gap, cell gap and/or, silicon tile warpage. The ongoing work deals with the thermomechanical performance simulation of the 3-tile LCoS microdisplay during operating conditions. The focus of this work is to maintain the critical parameters, cell and tile gap, within the prescribed tolerances. Finite element analysis has been used for this purpose and three-dimensional quarter symmetry models have been built to conduct a thorough study of the effect of operating conditions on the critical parameters. The proposed initial design was further improved by conducting parametric studies on material and dimensional parameters. Further, the sub-modeling technique has been used to conduct convergence studies that are essential in finite element analysis.
