Abstract：
OBJECTIVE: This study assesses musculoskeletal ultrasound (MSUS) knowledge, attitudes, and practices among young rheumatologists in Mexico, aiming to identify barriers and facilitators to its clinical use.
METHODS: An online survey distributed to a network of young rheumatologists captured demographics, institutional, and personal MSUS information. Multivariable analysis identified factors associated with positive MSUS attitudes.
RESULTS: Ninety-six rheumatologists (39.18% national response rate) completed the survey. Of respondents (54.2% females, median age 35.1 years), 81.2% deemed MSUS necessary in clinical rheumatology. The main barriers included limited training access (56.2%) and required training time (54.1%). Lack of scientific evidence was not a major barrier (60.4%). Positive MSUS attitudes were associated with learning from conferences (p = 0.029) and colleagues (p = 0.005), formal (p = 0.043), and in-person training (p = 0.020), MSUS use in practice (p = 0.027), and use by radiologists in their institute (p < 0.001). Interest in learning MSUS (88.5%) was significantly higher in those with positive attitudes (94.4%, p < 0.001). Elastic net analysis identified key drivers, including learning MSUS from conferences, colleagues, and in residency; using MSUS in practice; respondent-performed MSUS; and MSUS use by radiologists. Statistically significant associations were found with using MSUS for synovitis/inflammatory joint disease (OR = 1.43, 95% CI 1.00-2.05) and MSUS use by radiologists in respondent\'s institutes (OR = 1.70, 95% CI 1.20-2.90).
CONCLUSIONS: Most young rheumatologists in Mexico recognize the necessity of MSUS in clinical practice. By addressing identified barriers, encouraging rheumatologist-radiologist collaboration, and establishing a regulatory body to certify rheumatologist\'s MSUS experience, there is an opportunity to empower them with the necessary skills for effective MSUS use, ultimately benefiting patient care.

摘要：
目的：本研究评估肌肉骨骼超声（MSUS）知识，态度，以及墨西哥年轻风湿病学家的实践，旨在确定其临床使用的障碍和促进因素。
方法：发布给年轻风湿病学家网络的在线调查记录了人口统计学，机构,和个人MSUS信息。多变量分析确定了与积极MSUS态度相关的因素。
结果：96位风湿病专家（全国应答率39.18%）完成了调查。在受访者中(54.2%是女性，中位年龄35.1岁)，81.2%认为临床风湿病需要MSUS。主要障碍包括有限的培训机会（56.2％）和所需的培训时间（54.1％）。缺乏科学证据不是主要障碍（60.4%）。积极的MSUS态度与会议（p=0.029）和同事（p=0.005）的学习有关，形式(p=0.043)，和面对面培训(p=0.020)，MSUS在实践中使用（p=0.027），并由放射科医生在他们的研究所使用（p<0.001）。持积极态度的人对学习MSUS的兴趣（88.5%）明显更高（94.4%，p<0.001)。弹性网络分析确定了关键驱动因素，包括从会议中学习MSUS，同事们,和住院医师；在实践中使用MSUS；受访者执行的MSUS；以及放射科医生使用MSUS。使用MSUS治疗滑膜炎/炎性关节病（OR=1.43，95%CI1.00-2.05）和放射科医生使用MSUS在应答者机构（OR=1.70，95%CI1.20-2.90）之间存在统计学显著关联。
结论：墨西哥大多数年轻风湿病学家认识到MSUS在临床实践中的必要性。通过解决已确定的障碍，鼓励风湿病学家和放射科医生合作，并建立一个监管机构来证明风湿病学家的MSUS经验，有机会赋予他们有效使用MSUS的必要技能，最终有利于患者护理。
