A study investigated the relationship between shared communication links and the process of organizational innovation in a privately owned medical clinic providing comprehensive medical care to children and adults. Participants were the physicians and physician assistants employed at the clinic. Data were collected through questionnaires before and after the introduction of the innovation. The study hypothesized that the type and strength of communication links between individuals may determine the likelihood with which an individual will adopt an innovative idea. The hypothesis was not supported; several reasons may account for the lack of significant findings: (1) the innovation introduced was not salient for all members of the organization; (2) innovations are not championed in health care settings; (3) the clinic, like many health care settings, can be classified as a loosely coupled system and characterized as decentralized with a relative lack of coordination; and (4) participants in the study were unable to identify the primary content of their conversation with others and therefore could not identify multiplex links.
