Abstract: Objective　To explore the impact of the pre-anesthesia area (PAA) appointment process on the efficiency of preoperative anesthesia coordination, to compare the cooperation completion rate and average operation time before and after process optimization, and to evaluate the application value of an information-based closed-loop management system in enhancing surgical workflow integration. Methods　A retrospective controlled study was conducted. The data of 375 patients who underwent elective general anesthesia surgeries at First Affiliated Hospital of Sun Yat-sen University between May and June 2025 and required pre-anesthesia procedures in the PAA were collected. According to the implementation time of the optimized scheduling process, the patients were divided into a traditional scheduling group (May 2025; 188 cases) and an optimized scheduling group (June 2025; 197 cases). There were 102 males and 86 females in the traditional scheduling group who were (54.8±12.7) years old. There were 106 males and 91 females in the optimized scheduling group who were (55.3±11.9) years old. In the traditional scheduling group, the operating room nurses notified anesthesiologists of the required anesthesia procedures in paper form one day before surgery, with verbal communication of anesthesia operation needs on the day of surgery. The optimized scheduling group utilized an electronic mini-program for appointment booking, with anesthesiologists, pre-anesthesia nurses, and operating room nurses collaboratively managing patient transport and anesthesia procedures. The procedure cooperation frequencies, completion rates, and cooperation times were compared between the two groups. The enumeration data were analyzed using the chi-square test, and the measurement data the independent-sample t test. Results　The optimized scheduling group demonstrated a higher concentration of procedure types and significantly shorter mean times for the three most frequent pre-anesthesia procedures (all P<0.001): 197 procedures were completed in the optimized scheduling group, including femoral nerve block in 47 cases [88.68% and (16.5±2.1) min], internal jugular vein puncture in 134 cases [99.26% and (12.2±1.8) min], and radial artery puncture in 90 cases [100% and (9.5±1.2) min]; in the traditional scheduling group, 188 procedures were completed, including femoral nerve block in 36 cases [63.16% and (22.5±2.1) min], internal jugular vein puncture in 125 cases [96.15% and (19.2±1.8) min], and radial artery puncture in 83 cases [98.81% and (18.5±1.2)] min. The scores of information and education, procedural experience and safety, patient–clinician communication and responsiveness, and overall satisfaction in the optimized scheduling group were higher than those in the traditional scheduling group (15.66±2.15 vs. 14.89±2.32, 35.26±4.20 vs. 30.52±4.61, 20.97±3.72 vs. 15.04±2.29, and 81.79±5.82 vs. 70.28±6.01), with statistical differences (all P<0.001); there was no statistical difference in the score of perceived psychological support between the two groups (P=0.281). Conclusion　Optimization and implementation of the PAA appointment process significantly improves the timeliness of preoperative anesthesia cooperation, facilitates smoother surgical turnover, enables better allocation of recovery resources, and increases the efficiency of preoperative anesthesia coordination.
