General characteristics of study participants.

Introduction
Pneumatic tourniquets (PTs) play a crucial role in hemostasis during orthopedic surgery. This study aimed to investigate the current knowledge, attitudes, and practices (KAP) of orthopedic operating room personnel concerning the use of PTs.
Methods
This cross-sectional study was conducted from Jul. 2023 to Aug. 2023. An online questionnaire was used to collect demographic information and KAP score data of the orthopedic operating room personnel from Hangzhou Regional Hospitals.
Results
A total of 336 participants included orthopedic physicians (37.8%), orthopedic nurses (31.5%), anesthesiologists (8.9%), operating room nurses (19.9%) and medical students (1.8%). The median knowledge score was 28.5 (24, 32), with a maximum score of 38; the median attitude score was 31 (28, 35), of a maximum of 35; the median practice score was 41 (36, 44), of a maximum of 45. Correlation analysis showed links between knowledge and attitude (r = 0.388, p<0.001), knowledge and practice (r = 0.401, p<0.001), and attitude and practice (r = 0.485, p<0.001). Multivariate logistic regression analysis confirmed that female gender (OR = 0.294, 95% CI: 0.167–0.520; p<0.001), working in a specialized hospital (OR = 0.420, 95% CI: 0.219–0.803; p = 0.009), and occupation as a surgical anesthesiologist (OR = 3.358, 95% CI: 1.466–7.694; p = 0.004) were associated with better knowledge scores. A higher educational degree (OR = 0.237, 95% CI: 0.093–0.608; p = 0.003) was associated with better practice scores. No previous training was associated with lower knowledge (OR = 0.312, 95% CI: 0.187–0.520; p<0.001) and practice (OR = 0.325, 95% CI: 0.203–0.521; p<0.001) scores.
Conclusion
Orthopedic personnel in this study had acceptable knowledge, attitude, and practice concerning the use of PTs; additional training and guidance might enhance proficiency.

引言
气动止血带（Pneumatic tourniquets, PTs）在骨科手术止血过程中发挥关键作用。本研究旨在调查骨科手术室人员针对气动止血带使用的当前认知、态度与实践（Knowledge, Attitudes and Practices, KAP）现状。
方法
本横断面研究于2023年7月至2023年8月开展，采用在线问卷收集杭州区域医院骨科手术室人员的人口统计学信息及KAP评分数据。
结果
本研究共纳入336名参与者，其中骨科医师占37.8%、骨科护士占31.5%、麻醉医师占8.9%、手术室护士占19.9%，医学生占1.8%。认知评分中位数为28.5（四分位距：24~32），满分38分；态度评分中位数为31（四分位距：28~35），满分35分；实践评分中位数为41（四分位距：36~44），满分45分。相关性分析显示，认知与态度（r=0.388，p<0.001）、认知与实践（r=0.401，p<0.001）及态度与实践（r=0.485，p<0.001）之间均存在显著相关性。多因素logistic回归分析证实，女性（OR=0.294，95%CI：0.167~0.520；p<0.001）、在专科医院工作（OR=0.420，95%CI：0.219~0.803；p=0.009）以及职业为手术麻醉医师（OR=3.358，95%CI：1.466~7.694；p=0.004）与更高的认知评分显著相关。更高的学历水平（OR=0.237，95%CI：0.093~0.608；p=0.003）与更佳的实践评分相关。未接受过相关培训与更低的认知评分（OR=0.312，95%CI：0.187~0.520；p<0.001）及实践评分（OR=0.325，95%CI：0.203~0.521；p<0.001）显著相关。
结论
本研究中的骨科从业人员在气动止血带的使用方面具备可接受的认知、态度与实践水平；额外的培训与指导可进一步提升其操作熟练度。
