abstract = {BACKGROUND: Knowledge Translation (KT) plays a vital role in the modern health care community, facilitating the incorporation of new evidence into practice. Web 2.0 tools provide a useful mechanism for establishing an online KT environment in which health practitioners share their practice-related knowledge and experiences with an online community of practice. We have implemented a Web 2.0 based KT environment--an online discussion forum--for pediatric pain practitioners across seven different hospitals in Thailand. The online discussion forum enabled the pediatric pain practitioners to share and translate their experiential knowledge to help improve the management of pediatric pain in hospitals. OBJECTIVE: The goal of this research is to investigate the knowledge sharing dynamics of a community of practice through an online discussion forum. We evaluated the communication patterns of the community members using statistical and social network analysis methods in order to better understand how the online community engages to share experiential knowledge. METHODS: Statistical analyses and visualizations provide a broad overview of the communication patterns within the discussion forum. Social network analysis provides the tools to delve deeper into the social network, identifying the most active members of the community, reporting the overall health of the social network, isolating the potential core members of the social network, and exploring the inter-group relationships that exist across institutions and professions. RESULTS: The statistical analyses revealed a network dominated by a single institution and a single profession, and found a varied relationship between reading and posting content to the discussion forum. The social network analysis discovered a healthy network with strong communication patterns, while identifying which users are at the center of the community in terms of facilitating communication. The group-level analysis suggests that there is strong interprofessional and interregional communication, but a dearth of non-nurse participants has been identified as a shortcoming. CONCLUSIONS: The results of the analysis suggest that the discussion forum is active and healthy, and that, though few, the interprofessional and interinstitutional ties are strong},

abstract = {Providing patients with personalized educational messages can improve self-management of Cardiovascular Disease (CVD) risk factors. We present our compositional personalization approach that generates personalized educational material by dynamically selecting fine-grained information snippets, as per the patient profile, and then synthesizing them in a educational template to yield personalized patient education interventions. We apply our personalization approach in the PULSE system--Personalization Using Linkages of SCORE and behavior change readiness to web-based Education--that generates personalized patient education for CVD risk management. The PULSE framework involves the calculation of CVD risk assessment using the Systematic COronary Risk Evaluation (SCORE) algorithm, the estimation of readiness to change using the Transtheoretical Model (TTM) of intentional behavior change. The educational interventions were derived from evidence-based staged lifestyle modification materials and Canadian guidelines for CVD risk management.},

abstract = {The goal of this project is to augment clinician communication by connecting it to evidence-based research, providing explicit knowledge to corroborate the experiential knowledge shared between health care practitioners. The source of tacit knowledge sharing is the Pediatric Pain Mailing List (PPML), a forum for practicing clinicians to contact peers on the subject of pain in children. The messages, dating back to 1993, are processed for pertinent information and gathered together into threads. They are then parsed and connected to a set of MeSH keywords, which is used to search Pubmed and return a set of papers that correspond to the subject being discussed. The results are presented in an online forum, providing clinicians with an arena in which they can browse the archives of the PPML and connect those conversations to pertinent medical literature.},
