Characterizing the structure of operating room staffing using social network analysis.

BACKGROUND: : Very little research has been focused on the interdisciplinary staffing characteristics of the operating room team, an essential component of providing safe patient care in a high-risk setting.
OBJECTIVES: : The aim of this study was to determine how the operating room staffing of two surgical specialties compares in terms of social network variables.
METHODS: : Staffing data from all general and neurosurgical procedures performed at a large Midwestern hospital were analyzed using Social Network Analysis methods. Network variables include centrality, team coreness, and the core/periphery network structure. Multidimensional scaling, correlation, and descriptive statistics were used for the analysis.
RESULTS: : The core/periphery network structure was characteristic of both surgical services. Team coreness, a measure of how often the team worked together, was associated with the length of the case (p < .001). Procedure start time predicts the team coreness measure, with cases starting later in the day less likely to be staffed with a high core team (p < .001). Registered nurses constitute the majority of core interdisciplinary team members in both groups. DISCUSSION: : Analysis of the core/periphery structure of specialty team staffing networks indicates that many procedures are staffed with individuals who are associated peripherally with the specialty. Registered nurses as core group members are in a position to take a leadership role in the communication of norms and process variations to noncore members. The effect of having late starting cases staffed with a lower core team should be studied further because it pertains to patient outcomes. Future work should strive to account for the complex and dynamic nature of team development.
