Attitude dimension score distribution.

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
气压止血带（Pneumatic tourniquets, PTs）在骨科手术的止血操作中发挥着至关重要的作用。本研究旨在调查骨科手术室人员对气压止血带使用的认知、态度与实践（Knowledge, Attitudes and Practices, KAP）现状。
方法
本研究为横断面研究，于2023年7月至2023年8月开展。采用线上问卷的方式，收集杭州地区医院骨科手术室人员的人口统计学信息及KAP得分数据。
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%。认知得分的中位数为28.5（四分位距24~32），满分38分；态度得分中位数为31（四分位距28~35），满分35分；实践得分中位数为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）以及态度与实践（r=0.485, p<0.001）均存在显著关联。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）与更高的认知得分显著相关。更高的学历水平（OR=0.237, 95% CI: 0.093–0.608; p=0.003）与更优的实践得分相关。未接受过相关培训则与更低的认知得分（OR=0.312, 95% CI: 0.187–0.520; p<0.001）和实践得分（OR=0.325, 95% CI: 0.203–0.521; p<0.001）相关。
结论
本研究纳入的骨科从业人员在气压止血带的使用方面具备尚可的认知、态度与实践水平；补充相关培训与指导或可进一步提升其操作熟练度。
