Objective: To examine perceived operating room (OR) ergonomics facilitators and barriers, with a focus on the interdisciplinary team. Background: Poor ergonomics causes musculoskeletal injuries affecting all OR staff with repercussions on patient care, outcomes, and sustainability. Lack of ergonomic awareness and education are risk factors. Methods: We conducted a self-administered web-based survey of OR nurses, surgeons, and anesthesiologists at a single center (n = 238). We developed a questionnaire through item generation and reduction, followed by reliability and validity testing. Results: Response rate was 53.8%. Respondents perceived that on average 80% of nurses, 70% of surgeons, and 40% of anesthesiologists experienced musculoskeletal (MSK) injuries, with no difference in professional groups’ perceptions. Guideline ergonomics interventions were rarely used (<25%) except for specialized clothing (33%), equipment repositioning (59%), and seating (37%), though perceived as beneficial by 80% to 90%. Reported barriers to optimal ergonomics were organizational/structural (lack of time, space, equipment, funding), whereas solutions were individual. Fear of unfavorable perceptions from others was a concern for 62%. Teams discussing, prioritizing, monitoring, or helping with ergonomics was indicated by <50%. Individual ergonomic adaptations were perceived as convenience by other staff. Conclusions: While structural/organizational issues are reported as barriers to ergonomics, solutions appear as individual responsibilities. Team dynamics did not prioritize nor support ergonomics. Education tools leveraging the interdisciplinary team are warranted. This work will be supplemented by interviews and live observations to build tailored educational tools for OR teams.

Abstract Background This study compared the ergonomics of surgeons during deep inferior epigastric perforator (DIEP) flap surgery using either baseline equipment (loupes, headlights, and an operating microscope) or an exoscope. Plastic surgeons may be at high risk of musculoskeletal problems. Recent studies indicate that adopting an exoscope may significantly improve surgeon postures and ergonomics. Methods Postural exposures, using inertial measurement units at the neck, torso, and shoulders, were calculated in addition to the surgeons' subjective physical and cognitive workload. An ergonomic risk score on a scale of 1 (lowest) to 4 (highest) was calculated for each of the postures observed. Data from 23 bilateral DIEP flap surgeries (10 baseline and 13 exoscope) were collected. Results The neck and torso risk scores decreased significantly during abdominal flap harvest and chest dissection, while right shoulder risk scores increased during the abdominal flap harvest for exoscope DIEP flap procedures compared with. Exoscope anastomoses demonstrated higher neck, right shoulder, and left shoulder risk scores. The results from the survey for the “surgeon at abdomen” showed that the usage of exoscopes was associated with decreased performance and increased mental demand, temporal demand, and effort. However, the results from the “surgeon at chest” showed that the usage of exoscopes was associated with lower physical demand and fatigue, potentially due to differences in surgeon preference. Conclusion Our study revealed some objective evidence for the ergonomic benefits of exoscope; however, this is dependent on the tasks the surgeon is performing. Additionally, personal preferences may be an important factor to be considered in the ergonomic evaluation of the exoscope.

Background Long surgical procedures with loupe magnification and microscopes may put microsurgeons at an increased risk of musculoskeletal discomfort. Identifying the prevalence and impact of work-related musculoskeletal discomfort may guide preventive strategies to prolong well-being, job satisfaction, and career duration. Methods An online 29-question survey was designed to evaluate work-related musculoskeletal discomfort. The survey was created and distributed electronically through a private survey research center and was sent to the members of the American Society for Reconstructive Microsurgery. Results There were 117 respondents (16.7% response rate): 80% were men; 69% were aged 31 to 50 years; and 68% were in academic practice. On a scale of 0 to 10 (0, no pain and 10, worst pain), the median for work-related musculoskeletal discomfort for surgery without loupes or microscope was 2; with loupes, 4; and with a microscope, 5. Pain was most common in the neck. Half of the surgeons reported pain within 4 hours of surgery, and 57% feared that pain would influence future surgical performance. Surgeon discomfort affected posture (72%), stamina (36%), sleep (29%), relationships (25%), concentration (22%), and surgical speed (19%). Tremor caused by the discomfort occurred in 8%. Medical treatment for discomfort was sought by 29%. Time off work for treatment occurred for 8%. Conclusion Work-related musculoskeletal discomfort can affect many aspects of a microsurgeon's life and has the potential to limit a surgeon's ability to operate. Therefore, more emphasis is needed in the surgical community on the important issues of occupational health and surgical ergonomics for microsurgeons.

Abstract Background Surgical performance, provider health, and patient safety can be compromised when workload demands exceed individual capability on the surgical team. The purpose of this study is to quantify and compare intraoperative workload among surgical team members. Methods Observations were conducted for an entire surgical day for 33 participating surgeons and their surgical team at one medical institution. Workload (mental, physical, case complexity, distractions, and case difficulty) was measured for each surgical team member using questions from validated questionnaires. Statistical analyses were performed with a mixed effects model. Results A total of 192 surgical team members participated in 78 operative cases, and 344 questionnaires were collected. Procedures with high surgeon mental and physical workload included endovascular and gastric surgeries, respectively. Ratings did not differ significantly among surgeons and residents, but scrub nurses physical demand ratings were 14–22 (out of 100) points lower than the surgeons, residents, and surgical assistants. Residents reported the highest mental workload, averaging 19–24 points higher than surgical assistants, scrub nurses, and circulating nurses. Mental and physical demands exceeded 50 points 28–45 % of the time for surgeons and residents. Workload did not differ between minimally invasive and open techniques. Conclusion The workload questionnaires are an effective tool for quantifying intraoperative workload across the surgical team to ensure mental and physical demands do not exceed thresholds where performance may decrease and injury risk increase. This tool has the potential to measure the safety of current procedures and drive design of workload interventions.
