  We analyzed the relation between surgical service providers' network
structure and surgical team size with patient outcome during the operation. We
did correlation analysis to evaluate the associations among the network
structure measures in the intra-operative networks of surgical service
providers. We focused on intra-operative networks of surgical service
providers, in a quaternary-care academic medical center, using retrospective
Electronic Medical Record (EMR) data. We used de-identified intra-operative
data for adult patients who received nonambulatory/nonobstetric surgery in a
main operating room at Shands at the University of Florida between June 1, 2011
and November 1, 2014. The intra-operative dataset contained 30,211 unique
surgical cases. To perform the analysis, we created the networks of surgical
service providers and calculated several network structure measures at both
team and individual levels. We considered number of patients' complications as
the target variable and assessed its interrelations with the calculated network
measures along with other influencing factors (e.g. surgical team size, type of
surgery). Our results confirm the significant role of interactions among
surgical providers on patient outcome. In addition, we observed that highly
central providers at the global network level are more likely to be associated
with a lower number of surgical complications, while locally important
providers might be associated with higher number of complications. We also
found a positive relation between age of patients and number of complications.
