Objective:To explore Operating Room nurses' behavioral intentions regarding the implementation of isolation techniques in tumor surgery based on the theory of planned behavior (TPB) .Methods:This study was a qualitative research. A purposive sampling method was used to select 14 Operating Room nurses from the Affiliated Hospital of Qingdao University for semi-structured interviews from July to October 2023. An interview outline was developed based on TPB, and the Colaizzi 7-step method was used for data organization and analysis.Results:Among the 14 Operating Room nurses interviewed, two were male and 12 were female, with work experience ranging from one to 36 years and ages between 23 and 59 years. Based on TPB's three dimensions, including behavioral attitude, subjective norm, and perceived behavioral control, eight themes were identified: positive evaluation, negative evaluation, pressure from Operating Room managers and colleagues, pressure from surgeons, pressure from patients, lack of cognitive and skill motivation, work-related stressors as barriers, and analysis of real-world difficulties.Conclusions:Operating Room nurses hold a positive evaluation of implementing isolation techniques in tumor surgery, and their behavioral intention is influenced by nursing managers, surgeons, colleagues, and patients. However, there are also barriers such as a lack of knowledge and skill motivation, multiple work-related stressors, and incomplete institutional processes and standards.
