Brief 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.

Detailed Description

This study aims to reveal the crucial role of teamwork in surgical operations. Firstly, by calculating the degree of collaboration within the surgical team, we quantify the interactions, communication, and trust among team members, and subsequently analyze the impact of this collaboration on surgical team work efficiency indicators including pre-anesthesia preparation time, anesthesia induction time, and operation time, to identify optimal practices. Secondly, it analyzes how the degree of cooperation among surgical teams affects patient safety indicators such as intraoperative blood loss, the incidence of unplanned secondary surgeries, and the in-hospital mortality rate, thereby revealing the direct or indirect contribution of teamwork to patient safety. The impact of surgical team size, gender composition, and shift patterns on work efficiency and patient safety indicators was also analyzed.

Interventions

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.

Intervention Type: OTHER

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)."

Intervention Type: OTHER
