Poor operative ergonomics can lead to muscle fatigue and injury. However, formal ergonomics education is uncommon in surgical residencies. Our study examines the prevalence of musculoskeletal (MSK) symptoms, baseline ergonomics knowledge, and the impact of an ergonomics workshop in general surgery residents.
An anonymous voluntary presurvey and postsurvey was distributed to all general surgery residents at a single academic residency, assessing resident characteristics, MSK symptoms, and ergonomic knowledge before and after an ergonomics workshop. The workshop consisted of a lecture and a personalized posture coaching session with a physiatrist.
The presurvey received 33/35 (94%) responses. Of respondents, 100% reported some degree of MSK pain. Prevalence of muscle stiffness and fatigue decreased with increasing height. Females reported higher frequencies of MSK pain (P = 0.01) and more muscle fatigue than males (100% versus 73%, P = 0.03). All residents reported little to no ergonomics knowledge with 68% reporting that ergonomics was rarely discussed in the operating room. The postsurvey received 26/35 (74%) responses. Of respondents, 100% reported the workshop was an effective method of ergonomics education. MSK symptom severity improved in 82% of residents. Reports that ergonomics was rarely discussed in the operating room significantly decreased to 22.8% of residents (P < 0.01).
Surgical resident ergonomics knowledge is poor and MSK symptoms are common. Resident characteristics are associated with different MSK symptoms. Didactic teaching and personalized posture coaching improve ergonomics knowledge and reduce MSK symptom severity. Surgical residencies should consider implementing similar interventions to improve resident wellbeing.
不良的手术操作姿势可能导致肌肉疲劳和损伤。然而，手术住院医师培训中很少有正式的人体工程学教育。我们的研究调查了普通外科住院医师的肌肉骨骼（MSK）症状、基本人体工程学知识以及人体工程学工作坊的影响。
在一个学术住院医师项目中，向所有普通外科住院医师分发了一份匿名自愿预调查和后调查，以评估住院医师的特征、MSK 症状以及在人体工程学工作坊前后的人体工程学知识。该工作坊由物理治疗师进行讲座和个性化姿势指导组成。
预调查收到 33/35（94%）的回复。在回答者中，100%报告存在某种程度的 MSK 疼痛。肌肉僵硬和疲劳的发生率随身高的增加而降低。女性报告的 MSK 疼痛频率高于男性（100%比 73%，P=0.01），且更易感到肌肉疲劳（100%比 73%，P=0.03）。所有住院医师报告称他们几乎没有人体工程学知识，68%的人报告说在手术室中很少讨论人体工程学。后调查收到 26/35（74%）的回复。在回答者中，100%的人表示工作坊是人体工程学教育的有效方法。82%的住院医师的 MSK 症状严重程度有所改善。报告称在手术室中很少讨论人体工程学的人数显著减少至 22.8%（P<0.01）。
外科住院医师的人体工程学知识较差，MSK 症状普遍存在。住院医师的特征与不同的 MSK 症状相关。教学和个性化姿势指导提高了人体工程学知识，并降低了 MSK 症状的严重程度。外科住院医师培训应考虑实施类似的干预措施，以提高住院医师的幸福感。
