Abstract： Objective:To explore the implementation status and influencing factors of enhanced recovery after surgery (ERAS) in perioperative management of patients undergoing total hip arthroplasty.Methods:This study was a cross-sectional study. From May to December 2022, purposive sampling was used to select 186 orthopedic nurses from 9 ERAS pilot hospitals in Beijing as the research subject. A self-designed questionnaire was used to investigate the implementation status of ERAS. Pearson correlation was used to analyze the correlation between Nurse ERAS Implementation Status Questionnaire scores and ERAS Behavioral Intention Questionnaire scores. Multiple linear regression was used to analyze the influencing factors of ERAS in perioperative nursing of patients undergoing total hip arthroplasty.Results:A total of 186 questionnaires were distributed and 186 valid questionnaires were collected, with an effective response rate of 100.00% (186/186). The total score of the Nurse ERAS Implementation Status Questionnaire was (116.49±20.71), and the standardized scores for each dimension from high to low were follow-up management (80.22±20.44), intraoperative period (78.98±15.17), preoperative period (74.72±14.09), and postoperative period (69.77±15.94). The total score of the ERAS Behavioral Intention Questionnaire was (77.39±15.08), and the standardized scores of each dimension from high to low were subjective norm (79.93±19.01), behavioral intention (77.69±19.61), behavioral attitude (74.19±15.77), and perceived behavioral control (64.41±14.69). The nurse's professional title, familiarity with ERAS, ERAS training, and subjective norm were the influencing factors of the specific implementation status score of ERAS ( P<0.05), explaining 40.9% of the total variance. Conclusions:Nurses should strengthen training on ERAS, increase their familiarity with knowledge, and adopt various incentive measures to further enhance the implementation of ERAS programs in clinical practice.
