The Paradox of Network Inequality: Differential Impacts of Status and Influence on Surgical Team Communication.

INTRODUCTION

Introduction: Healthcare is a dynamic and complex system predisposed to adverse events caused by human and technical errors. The ability of multidisciplinary clinicians to effectively communicate clinical information influences healthcare quality. Authority gradients, culture, and organizational hierarchy frequently constrict communication and contribute to surgical adverse events. Hierarchy is especially pronounced in military medicine, where military status, rank, and professional roles potentially create barriers to communication.

METHODS

We used an exploratory, prospective, cross-sectional design to determine how the social structure of military surgical teams influences group (network) communication effectiveness. Using a social network questionnaire, we surveyed members of surgical teams concerning their close-working relationships with other team members and perceptions of their communication effectiveness. We addressed the following research question: In surgical teams, how do the status (indegree) and influence (outdegree) of its individual members impact communication within the team?

RESULTS

We surveyed 50 surgical teams comprised of 45 clinicians and found that for close-working relationship networks communication effectiveness improved with lower concentrations of status and higher concentrations of influence. Network indegree (i.e., status) (β=-0.893, p=.019) had a larger impact than outdegree (i.e., influence) (β=0.617, p=.015), indicating status had a larger effect on communication effectiveness than influence. Put simply, our results show communication improves when there is more equality of status in the surgical team. Paradoxically, communication improves when there are higher concentrations of network influence among surgical team members.

CONCLUSIONS

Inequality in surgical team networks has paradoxical effects on communication effectiveness. The impact of network structure on organizational behavior is of high interest to the military and provides essential insights into clinicians' ability to communicate in a highly complex and task-based environment. Communication will likely improve in surgical teams through methods to foster equality of team member status and promote surgical leadership. Military medical policies could both amplify the positive effects and mitigate the negative effects of network inequality.
