"11 CoPs are reported to ease knowledge management and learning, and foster sharing of tacit knowledge.9 CoPs can contribute to improving health care measured through cost savings, increased professional competencies, the reduction of geographical and organizational barriers and professional isolation, and the implementation of new processes and technologies.9,12 Virtual methods seem to be effective in supporting CoP knowledge sharing and communication among CoP members, notably through the use of virtual forums and electronic sharing of resources.9,12 http://ovidsp.tx.ovid.com.ezproxy.usherbrooke.ca/sp-3.21.1b/ovidweb.cgi Virtual CoPs (vCoPs) are comprised of three groups: the core, the active, and the peripheral members.13 Most members are peripheral, rarely participating actively, but gaining insight from reading discussions, whereas active members participate occasionally in the CoP but not to the extent of the core group.13 A common model in health care is to have a core group composed of a coordinator and clinical leaders, who act as facilitators, have content and resource expertise, and enable social processes (eg, create an engaging climate).14 Some evidence suggests that a face-to-face meeting of the vCoP members can be important before meeting through virtual methods, whereas other studies have demonstrated that groups, who met solely or largely in virtual environments, can also function quite effectively.…”
