MUSIC trial will establish an infrastructure for communications (and therefore dissemination) by building a robust framework in which dialogue and interaction can take place. This applies equally to internal and external communication. These will be used to disseminate information about and solicit input into the Single-Port-Access Surgery project work. Contact can be maintained and facilitated by electronic mailing lists, through Internal Lists within the EAES members, and External Lists including stakeholders using several existing lists to communicate to the wider community.
