Team Familiarity and Perioperative Outcomes in Non-Cardiac Surgery
Sponsor: Zhongda Hospital
Summary
The goal of this retrospective observational study is to quantify the impact of team collaboration on work efficiency in operating room and patient safety outcomes in non-cardiac surgical teams. The main purpose is to answer: How does team collaboration affect work efficiency in operating room and patient safety outcomes during/after surgery? The data will be obtained from the Hospital Electronic Medical Record Information System, participants already finished all the planned surgeries.

Surgical team familiarity
Surgical team familiarity: the degree of collaboration within the surgical team is statistically described based on data regarding team personnel and composition, which is used to calculate the Intraoperative Familiarity Score (IFS)-the core component of this study. The specific methodology includes IFS=（X1+X2+X3+X4+X5+X6…）/ N N=nCr=n!/r!(n-r)! Here, X represents the number of times a pair of team members has worked together over a specified period (this process is repeated for all possible pairings in the team), and N is the total number of possible pairwise combinations in the team.
Composition and Dynamics of the Surgical Team
Basic indicators reflecting surgical team personnel and composition: 1. Number of surgical, anesthesia, and nursing team members participating in procedures: are obtainable via the Anesthesia Information Management System (AIMS). 2. Shift changes among surgical, anesthesia, and nursing teams during individual procedures: can be tracked through the AIMS. 3. Gender ratio within surgical, anesthesia, and nursing teams: will be derived from the Hospital Information System (HIS)."
