Effect of laparoscopic handle size on surgical performance: A randomized crossover trial. Med Eng Phys 2024; 127:104165. [PMID: 38692768 DOI: 10.1016/j.medengphy.2024.104165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 03/02/2024] [Accepted: 04/02/2024] [Indexed: 05/03/2024]
Abstract
Laparoscopic instrument handles design and dimensions are crucial to determine the configuration of surgeons' hand grip and, therefore, can have a deleterious effect on overall surgical efficiency and surgeons' comfort. The aim of this study is to investigate the impact of laparoscopic handle size and hand surface area on surgical task performance. A single-blind, randomized crossover trial was carried out with 29 novice medical students. Participants performed three simulated tasks in "black box" simulators using two scissor-type handles of different sizes. Surgical performance was assessed by the number of errors and time required to complete each task. Hand anthropometric data were measured using a 3D scanner. Execution time was significantly higher when cutting and suturing tasks were performed with the smaller handle. In addition, hand surface area was positively correlated with peg transfer task time when performed with the standard handle and was correlated with cutting task time in small and standard handle groups. We also found positive correlations between execution time and the number of errors executed by larger-handed participants. Our findings indicate that laparoscopic handle size and hand area influence surgical performance, highlighting the importance of considering hand anthropometry variances in surgical instrument design.

A Tubular-Mounted Digital Camera Versus Optical Surgical Microscope for Minimally Invasive Lumbar Decompression Surgery: The Impact on Operative Times, Ergonomics, and Workflow. World Neurosurg 2024; 184:e65-e71. [PMID: 38218447 DOI: 10.1016/j.wneu.2024.01.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 01/04/2024] [Accepted: 01/05/2024] [Indexed: 01/15/2024]
Abstract
OBJECTIVE Understanding ergonomic impact is foundational to critically evaluating value and safety of enabling technologies in minimally invasive spine surgeries. This study assessed the impact of a tubular-mounted digital camera (TMDC) versus an optical surgical microscope (OSM) in single-level minimally invasive spine surgeries on operative times, durotomy rate, surgeon ergonomics, safety, and operating room workflow. METHODS This retrospective study compared consecutive single-level minimally invasive lumbar decompression surgeries in a TMDC cohort (September 2021-June 2022) with an historical OSM cohort (January 2020-July 2021). Data included patient demographics, operative times, durotomy incidence, surgeon ergonomics (Rapid Entire Body Assessment scores), and equipment impact via staff surveys. Operative times were assessed by t test, while Pearson χ2 test compared sex. Age, body mass index, and Charlson Comorbidity Index comparisons were made by Wilcoxon rank sum tests, and survey results were analyzed with Wilcoxon signed rank tests. RESULTS TMDC and OSM groups included 74 and 82 patients, respectively. Age, sex, and Charlson Comorbidity Index did not significantly differ between groups. The TMDC group had a higher body mass index (29.6 ± 5.1) than the OSM group (29.0 ± 7.5) (P = 0.04). The TMDC group had significantly shorter operative times (57.3 ± 16.6 minutes) than the OSM group) (66.7 ± 22.5 minutes) (P = 0.004), with no difference in durotomy rates (P = 0.42). TMDC use yielded lower Rapid Entire Body Assessment scores compared with OSM (4.1 ± 0.77) (P < 0.001). Surveys indicated improved safety, setup time, and workflow with TMDC (P < 0.001). CONCLUSIONS TMDC in single-level minimally invasive lumbar decompression surgery improved surgeon ergonomics, reduced operative times, and maintained durotomy rates, enhancing operating room efficiency. Evaluating ergonomic impact of technology is vital for safety and value assessment.

Prevalence of disability secondary to work-related musculoskeletal injuries among orthopaedic surgeons. J Clin Orthop Trauma 2024; 51:102402. [PMID: 38751749 PMCID: PMC11092878 DOI: 10.1016/j.jcot.2024.102402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 04/08/2024] [Indexed: 05/18/2024] Open
Abstract
Background Orthopaedic surgeons encounter many work-place hazards that can lead to musculoskeletal injuries (MSI) and their clinical sequelae. This study aims to evaluate musculoskeletal injuries among orthopaedic surgeons and compare their rates of disability claims and time off work. Additionally, this study provides a perspective on the financial impact of work-related injuries among orthopaedic surgeons. Methods An electronic survey was developed to assess work-place hazards among orthopaedic surgeons. The survey included questions on demographics, musculoskeletal injuries, and disabilities. Electronic surveys were emailed to all current members of the American Academy of Orthopaedic Surgeons (AAOS) between March and April 2021 in the United States. Descriptive statistics were run for all variables and chi-squared and t-tests when applicable. Results 1645 members of the AAOS completed the survey (7.03 % response rate), and 243 (14.9 %) reported a work-related injury to their place of employment at some point during their career. Of the respondents, 1129 (76.4 %) reported having active disability insurance, and 61 (3.7 %) orthopaedic surgeons filed a disability claim secondary to a work-related injury at some point during their career. Of the surgeons that claimed disability, 39 (66.1 %) returned to work, and 20 (33.9 %) had an early retirement. Foot/ankle injuries led to the highest rates of early retirement overall (62.5 %). Conclusion This study captures the prevalence of disability claims made by orthopaedic surgeons due to work-place hazards. To our knowledge, this is the first study to broadly compare disability claims amongst orthopaedic surgeons. This data should be used to implement changes in the orthopaedic community to decrease injuries and disability claims.

Gender differences in ergonomics during simulated ureteroscopy. Am J Surg 2024:S0002-9610(24)00130-2. [PMID: 38443269 DOI: 10.1016/j.amjsurg.2024.02.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 01/25/2024] [Accepted: 02/20/2024] [Indexed: 03/07/2024]
Abstract
BACKGROUND Female urologists report higher rates of work-related physical discomfort compared to male urologists. We compared ergonomics during simulated ureteroscopy, the most common surgery for kidney stones, between male and female urologists. METHODS Surface electromyography was used to measure muscle activation during common ureteroscopic tasks in urology trainees and staff with different surgeon positions and ureteroscopes. Subjective workload was assessed using the NASA Task Load Index (NASA-TLX). Paired t-tests, Wilcoxon rank-sum tests, and multivariate regressions were used to compare muscle activation by gender for each trial condition. RESULTS There was no difference in age or distribution of training level between genders, though men had larger glove sizes. Across all conditions, women required greater muscle activation in multiple muscle groups and had greater NASA-TLX scores compared to men. CONCLUSIONS There may be gender differences in ergonomics during ureteroscopy based on muscle activation and subjective workload, suggesting potential for personalizing surgical ecosystems.

Abstract
OBJECTIVE The main objective of this study was to develop and evaluate the feasibility and effectiveness of a novel exoskeleton system designed to provide ergonomic assistance to surgeons while preserving or improving the quality of endoscopic sinus and skull base surgical procedures. METHODS To evaluate the functionality and ergonomic characteristics of the device, five experiments were conducted in different and increasingly realistic scenarios: silicone model of the nasal cavity, freshly frozen cadavers and finally in a real surgery. Each volunteer's task was recorded and timed. The National Aeronautics and Space Administration Task Load Index (NASA-TLX) rating scale was used to estimate the surgeons' workload while performing the tasks. RESULTS Twenty-five volunteers took part in the experiments. Volunteers perceived more comfort and less fatigue and pain when using the armrest than when not using the device (3.3, SD 1.75 vs. 5.9 SD 1.49; p = 0.02). Participants found the device intuitive, comfortable, and improving accuracy and stability with endoscope use. CONCLUSION A new system that provides ergonomic assistance to surgeons was tested in simulation surgery with acceptable usability. Initial results in terms of pain and fatigue reduction and efficiency were excellent, justifying further research into this technology. LEVEL OF EVIDENCE NA Laryngoscope, 134:79-86, 2024.

Abstract
BACKGROUND AND OBJECTIVES Radical prostatectomy (RP) is a definitive surgical therapy for localized prostate cancer. Evidence suggests that the poor ergonomics of surgeons during RP may lead to work-related musculoskeletal disorders and loss of productivity. Since each surgery modality has its physical demands, we compared the ergonomic risk between laparoscopic (LRP) and robotic-assisted (RARP) radical prostatectomy. METHODS The study assessed the posture of 10 urological surgeons during LRP and RARP surgeries with the Rapid Entire Body Assessment (REBA) scale. RESULTS We found that the RARP approach resulted in lower REBA scores over the LRP procedure. CONCLUSIONS Robotic surgery improves body posture for the urological surgeon like in other medical specialties. However, the surgeons display harmful postures in both surgeries.

Abstract
Objective Endoscopic transnasal skull base surgery is a valuable technique used in the surgical treatment of various skull base pathologies. In such surgeries, the reconstruction of the skull base is crucial for surgical success and minimizing complications. This study presents a new side-support surgical tray designed to improve the exposure of the lateral femoral surgical area during surgery, enhancing surgical efficiency and reducing the risk of surgical complications. The study compared this innovative tray stand with the conventional double-sided support tray stand to evaluate its impact on surgical procedures and complications. Materials and methods The study prospectively analyzed 248 endoscopic transnasal skull base surgeries requiring lateral femoral autologous tissue harvesting. One hundred fifty-eight cases were performed using the side-support surgical tray stand (experimental group), while 90 cases used the conventional double-sided support tray stand (control group). Various parameters were evaluated, including satisfaction scores of surgeons, circulating nurses, instrument nurses, and anesthetists, as well as objective outcomes such as surgical duration and the incidence of complications. Results Surgeons in the experimental group expressed higher satisfaction with the surgical field exposure and the portability of the surgical tray stand compared to the control group. Likewise, circulating nurses in the experimental group reported greater satisfaction with the installation and portability, surpassing that of the control group (p< 0.01). Although the stability of instrument nurses in the experimental group was slightly less than that of the control group, it had no discernible impact on surgical cooperation. Anaesthesiologists in the experimental group exhibited higher satisfaction regarding the convenience of intraoperative monitoring and management than their counterparts in the control group. The average duration required for intraoperative autologous tissue harvesting in the experimental group was significantly shorter than in the control group (p < 0.01). Furthermore, the incidence of postoperative wound infections and intracranial infections in the experimental group was notably lower than in the control group (would infections, p = 0.046; intracranial infection, p = 0.025). Conclusion The novel side-support surgical tray stand effectively improves surgical exposure, convenience, and safety while reducing the risk of surgical site and intracranial infections. It also shortens surgical duration and lowers complication rates, making it a suitable choice for clinical application.

Abstract
Background Surgical fatigue syndrome (SFS) is a frequent, but underestimated, entity that occurs during laparoscopic surgeries. It could impair surgical outcomes, patient safety, and surgeon health. Furthermore, current surgical education lacks effective interventions to avoid it. Discomfort represents the most common manifestation and includes musculoskeletal fatigue, numbness, or frank pain. The most common affected sites are the back neck, dominant hand shoulder, and high or low back. We propose an integral intervention (surgeon posture, instruments/devices design & use and discomfort improvement) that prevents or mitigates SFS. Methods An experimental study was conducted on 57 general surgery residents and general surgeons. Participants in the experimental and control group executed standardized laparoscopic knots in a simulator and knowledge, body discomfort, and posture/ergonomic risk was evaluated before and after intervention application. Results A statistically significant decrease in discomfort intensity was found in the experimental group. Also, discomfort presentation by the anatomic site diminishes and surgical performance improves. Conclusions Intervention prevents or mitigates discomfort associated with muscle-skeletal component of SFS. ACGME competency Practice Based-Learning and Improvement.

Abstract
Worker and work-related musculoskeletal symptoms are prevalent among surgeons operating on human patients. Despite incidence rates for accidents among veterinarians and their staff being 2.9 times higher than that of general practitioners of human medicine, little is known about musculoskeletal symptoms among veterinary surgeons. In this study, 212 board-certified members of the American College of Veterinary Surgeons responded to a survey regarding various work-related activities and their experience with musculoskeletal symptoms in 10 different body regions. Across all body regions, reported pain increased from before to after a typical day of surgery (p <.01). Gender, weight, age, and years performing surgery were worker factors that were related to pain (p <.05), while number of procedures, practice focus, and proportion of minimally invasive surgery were work factors related to pain (p <.05). Our findings suggest that musculoskeletal symptoms are prevalent among veterinary surgeons and may help provide evidence for guidelines for minimising musculoskeletal injuries in veterinary surgery.Practitioner summary: Little is known about the risk factors for musculoskeletal symptoms (MSS) among veterinary surgeons. This cross-sectional survey of veterinary surgeons investigates worker and work factors related to MSS. We show that MSS are prevalent and identify key factors providing evidence that MSS are a concern in veterinary surgery.

Abstract
The aim of the study was to examine the factors which may influence suboptimal ergonomic surgeon hand positioning during robotic colorectal surgery (RCS). An observational study of 11 consecutive RCS cases from June 2022 to August 2022 was performed. Continuous video footage of RCS cases was analysed concurrently with video recordings of surgeon's hand positions at the console. The outcome studied was the frequency with which either hand remained in a suboptimal ergonomic position outside the predetermined double box outlines, as marked on the surgeon's video, for >1 min. Situations which resulted in poor upper limb ergonomics were dissection in the peripheral operating field location, left-hand use, use of the stapler, dissection of the main mesenteric blood vessels, and multi-quadrant surgery. Being aware of situations when suboptimal ergonomic positions occur can allow surgeons to consciously compensate by using the clutch or pausing to take a rest break. What does this paper add to the literature? The study is important because it is the first to look at factors which may influence poor upper limb ergonomics during non-simulated RCS. By recognizing these factors and compensating for them, it may improve surgeon ergonomics with resultant better performance.

Abstract
The recent development of high-resolution, heads-up, 3D visualization microscopy systems has provided new technical and visualization options for ophthalmic surgeons. In this review, we explore the evolution of microscope technologies, the science behind modern 3D visualization microscopy systems, and the practical benefits (as well as disadvantages) that these systems provide over conventional microscopes for intraocular surgical practice. Overall, modern 3D visualization systems reduce the requirements for artificial illumination and provide enhanced visualization and resolution of ocular structures, improving ergonomics, and facilitating a superior educational experience. Even when considering their disadvantages, such as those related to technical feasibility, 3D visualization systems have an overall positive benefit/risk ratio. It is hoped these systems will be adopted into routine clinical practice, pending further clinical evidence on the benefits they may provide on clinical outcomes.

Abstract
INTRODUCTION Our prototype wireless full-HD Augmented Reality Head-Mounted Display (AR-HMD) aims to eliminate surgeon head turning and reduce theater clutter. Learning and performance versus TV Monitors (TVM) is evaluated in simulated knee arthroscopy. METHODS 19 surgeons and 19 novices were randomized into either the control group (A) or intervention group (B) and tasked to perform 5 simulated loose-body retrieval procedures on a bench-top knee arthroscopy simulator. A cross-over study design was adopted whereby subjects alternated between devices during trials 1-3, deemed the "Unfamiliar" phase, and then used the same device consecutively in trials 4-5, to assess performance in a more "Familiarized" state. Measured outcomes were time-to-completion and incidence of bead drops. RESULTS In the unfamiliar phase, HMD had 67% longer mean time-to-completion than TVM (194.7 ± 152.6s vs 116.7 ± 78.7s, P < .001). Once familiarized, HMD remained inferior to TVM, with 48% longer completion times (133.8 ± 123.3s vs 90.6 ± 55s, P = .052). Cox regression revealed device type (OR = 0.526, CI 0.391-0.709, P < .001) and number of procedure repetitions (OR = 1.186, CI 1.072-1.311, P = .001) are significantly and independently related to faster time-to-completion. However, experience is not a significant factor (OR = 1.301, CI 0.971-1.741, P = .078). Bead drops were similar between the groups in both unfamiliar (HMD: 27 vs TVM: 22, P = .65) and familiarized phases (HMD: 11 vs TVM: 17, P = .97). CONCLUSION Arthroscopic procedures continue to be better performed under conventional TVM. However, similar quality levels can be reached by HMD when given more time. Given the theoretical advantages, further research into improving HMD designs is advocated.

Abstract
Purpose To study the prevalence of musculoskeletal disorder (MSD) and the associated occupational risk factors among Indian ophthalmologists, including residents and fellows. Methods A cross-sectional survey was conducted among ophthalmologists in India using a semi-structured questionnaire in a web-based survey. The questionnaire was prepared in English after extensive literature research and consulting with subject experts. It was pretested on ten ophthalmologists and after confirming that there were no ambiguities, the questionnaire was circulated. After providing informed consent online and ensuring the confidentiality of information, respondents could fill out the questionnaire containing questions to assess demographic details, risk factors, and musculoskeletal symptoms. Results We received 551 valid responses, out of which 74.77% reported musculoskeletal symptoms since starting practice in ophthalmology. We found a statistically significant association of work-related MSD with greater hours of practice, a higher number of hours of surgery, and a larger patient load. The self-reported symptoms were maximum in lower back (56.55%), followed by neck (49.03%), upper back (38.59%), and shoulder (23.79%). As a remedial measure, 58.98% resorted to rest while only 8.98% consulted orthopedist. Only 46% were aware of good ergonomic practices. Surgery (74.5%), indirect ophthalmoscopy (51.69%), and slit-lamp examination (50.73%) were reported as the major culprits. Respondents declared an interference with personal life (39.56%), with work (33.74%) as well as having caused psychological stress (43.2%) due to work-related MSD. Conclusion A vast majority of our respondents reported work-related MSD. Major risk factors were hours of practice, hours of surgery, higher body mass index, sedentary lifestyle, and higher patient load. The awareness of ergonomic practices was low.

Abstract
OBJECTIVE The comparative postural health of surgeons performing endoscopic and microscopic otologic surgeries has been a topic of active debate, with many nascent or anecdotal reports suggesting the latter encourages suboptimal ergonomics. Using inertial body sensors to measure joint angles, this study sought to objectively evaluate and compare the ergonomics of surgeons during endoscopic and microscopic otologic surgeries. STUDY DESIGN Prospective pilot trial. SETTING Large, multicenter, academic hospital system. Performed 21 otologic operations (10 endoscopic and 11 microscopic) in November 2020 and January 2021. All attendings were fellowship trained in otology/neurotology. SUBJECTS Eight otolaryngologists (four attendings and four residents) performing 21 otologic surgeries (11 microscopic and 10 endoscopic). INTERVENTION Approach to otologic surgery: endoscope or microscope. MAIN OUTCOME MEASURES Surgeons' neck and back angles while wearing ergonomic sensors affixed to either side of each major joint, mental and physical burdens and pain after each surgery (via modified NASA Task Load Index). RESULTS Residents' necks (9.54° microscopic vs. -4.79° endoscopic, p = 0.04) and backs (16.48° microscopic vs. 3.66° endoscopic, p = 0.01) were significantly more flexed when performing microscopic surgery than when performing endoscopic surgery, although attending neck and back flexion were comparable during microscopic and endoscopic surgeries. Attendings reported significantly higher pain levels after operating microscopically than after operating endoscopically (0.13 vs. 2.76, p = 0.01). CONCLUSIONS Residents were found to operate with significantly higher risk back and neck postures (as defined by the validated ergonomic tool, Rapid Entire Body Assessment) when operating microscopically. Attendings reported significantly higher levels of pain after operating microscopically versus endoscopically, suggesting that the suboptimal microscopic postures adopted earlier in training may pose an indelible risk later in a surgeon's career.

Patients with DQT between 2001 and 2017 from the Taiwan National Health Insurance Research Database were the DQT cohort. The 1:1 propensity score matching method was applied for creating control cohort. The primary outcome was defined as new-onset of AC at least 1 year after the date of confirmed diagnosis of DQT. In total, 32,048 patients with mean age 45.3 years were included. DQT was significantly positively associated with risk of new-onset AC after adjustment for baseline characteristics. Furthermore, severe DQT requiring rehabilitation was positively associated with risk of new-onset AC. In addition, male gender and age under 40 may be additional risk factors for new-onset AC, compared to female gender and age over 40. Cumulative incidence of AC after 17 years was 24.1% among patients with severe DQT requiring rehabilitation and was 20.8% among patients with DQT without rehabilitation. This is the first population-based study to demonstrate an association between DQT and new-onset AC. The findings recommend that preventive occupational therapy, including active modification for the shoulder joint and adjustments to daily activities, may be necessary for patients with DQT to reduce their risk of developing AC.

Abstract
BACKGROUND The prevalence of work-related musculoskeletal disorders (WRMD) is increasing among all surgical specialties. OBJECTIVE Results of a cross-sectional survey of hair transplant surgeons were analyzed, with the aims to (1) determine the prevalence of WRMD, (2) assess risk factors associated with musculoskeletal (MSK) symptoms, and (3) identify mitigation measures. MATERIALS AND METHODS A survey pertaining to demographics, MSK-related symptoms and its impacts, and pain mitigation measures taken, if any, were distributed to 834 hair transplant surgeons. Risk factors associated with pain severity were assessed using linear regression. RESULTS Overall, 78.5% (73 of 93) respondents had experienced pain when performing surgery. Musculoskeletal symptoms were most severe in the neck, followed by upper/lower back, and extremities. Number of grafts performed per session of follicular unit extraction positively correlated with pain severity; female surgeons and surgeons aged >71 years were at higher risk. A majority expressed concern that WRMD may limit their career and agreed to a need for improved workplace education. Strength training and ergonomic improvements of surgical procedure were not commonly adopted. CONCLUSION In sum, WRMD can be debilitating in health care professionals. Workplace ergonomic adjustments and physical exercise programs may be warranted to better mitigate MSK symptoms.

A narrative review of ergonomic problems, principles, and potential solutions in surgical operations. Surgery 2023:S0039-6060(23)00177-0. [PMID: 37202309 DOI: 10.1016/j.surg.2023.04.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 04/03/2023] [Accepted: 04/05/2023] [Indexed: 05/20/2023]
Abstract
BACKGROUND Ergonomic development and awareness are critical to the long-term health and well-being of surgeons. Work-related musculoskeletal disorders affect an overwhelming majority of surgeons, and various operative modalities (open, laparoscopic, and robotic surgery) differentially affect the musculoskeletal system. Previous reviews have addressed various aspects of surgical ergonomic history or methods of ergonomic assessment, but the purpose of this study is to synthesize ergonomic analysis by surgical modality while discussing future directions of the field based on current perioperative interventions. METHODS pubmed was queried for "ergonomics," "work-related musculoskeletal disorders," and "surgery," which returned 124 results. From the 122 English-language papers, a further search was conducted via the articles' sources for relevant literature. RESULTS Ninety-nine sources were ultimately included. Work-related musculoskeletal disorders culminate in detrimental effects ranging from chronic pain and paresthesias to reduced operative time and consideration for early retirement. Underreporting symptoms and a lack of awareness of proper ergonomic principles substantially hinder the widespread utilization of ergonomic techniques in the operating room, reducing the quality of life and career longevity. Therapeutic interventions exist at some institutions but require further research and development for necessary widespread implementation. CONCLUSION Awareness of proper ergonomic principles and the detrimental effects of musculoskeletal disorders is the first step in protecting against this universal problem. Implementing ergonomic practices in the operating room is at a crossroads, and incorporating these principles into everyday life must be a priority for all surgeons.

Psychological Stress and Hand Eczema in Physicians and Dentists: A Comparison Based on Surgical Work. Behav Sci (Basel) 2023; 13:bs13050379. [PMID: 37232616 DOI: 10.3390/bs13050379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 04/17/2023] [Accepted: 04/26/2023] [Indexed: 05/27/2023] Open
Abstract
BACKGROUND This research looks at the connection between psychological stress and the prevalence of hand eczema (HE) among physicians and dentists (surgeons, non-surgeons). METHODS This cross-sectional field study involved 185 participants: physicians (surgeons, non-surgeons), dentists (surgeons, non-surgeons) and controls. Hand lesions were examined using the Osnabrueck Hand Eczema Severity Index (OHSI), and participants answered the Nordic Occupational Skin Questionnaire (NOSQ) and Perceived Stress Scale (PSS). Patch tests were performed using commercial contact allergens. RESULTS The estimated prevalence of HE (self-reported) was 43.9% (physicians 44.6%; dentists 43.2%). HE was significantly more reported by surgeons than controls (p < 0.004; V = 0.288). Degrees of perceived stress (PSS) did not differ significantly between the groups, though physicians non-surgeons most exhibited high stress (50%), and physicians surgeons most exhibited low stress (22.5%). High stress was associated with 2.5 higher odds for self-reported HE (p = 0.008). Low stress was greater among physicians/dentists who did not report eczema (41.0% vs. 24.6%); moderate stress was more common among those who reported eczema (72.3% vs. 51.8%; p = 0.038; V = 0.210). CONCLUSIONS Since high stress levels may negatively influence physicians'/dentists' work and quality of life, measures to decrease stress could be introduced into the treatment of healthcare workers who are prone to it.

Abstract
Musculoskeletal pain and disorders (MSDs) constitute a well-recognised occupational hazard to the dental community. Fortunately, they are preventable. Dental office ergonomics plays a key role in addressing these musculoskeletal challenges. An ergonomic improvement project based on Kotter's eight-step change model management theory was implemented within a dental practice. The project provided valuable evidence-based ergonomic interventions to prevent or reduce MSDs. The task force motivated staff to engage in strategies and interventions to enact an ergonomic vision. This case study represents an action plan to guide this ergonomic change. The key results of this project were an evidence-based ergonomics health promotional brochure, reduced sick leave attributable to MSDs, and workplace ergonomic checkpoints. The ergonomic change model represents an ongoing process where innovative trends and evaluative methods can be supported. Research limitations and practical implications were acknowledged.

Knowledge, Attitudes, and Practices Regarding Ergonomic Hazards Among Healthcare Workers in a Saudi Government Hospital. J Multidiscip Healthc 2022; 15:1771-1778. [PMID: 36042943 PMCID: PMC9420414 DOI: 10.2147/jmdh.s371361] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Accepted: 08/10/2022] [Indexed: 11/24/2022] Open
Abstract
Background Musculoskeletal disorders (MSDs) affecting healthcare workers (HCWs) must be considered and addressed as a serious issue. Thus, it is important to incorporate ergonomics into clinical practice to prevent MSDs. The objectives of this study were to investigate HCWs’ knowledge, attitudes, and practices regarding ergonomics in a large governmental healthcare facility. Methods A cross-sectional study was conducted in which the participants were interviewed to complete a validated four-section questionnaire (demographic data, knowledge, attitudes, and practice information related to ergonomics). The questionnaire was newly self-developed based on a literature review and was pilot tested after development. Results This study included 273 HCWs. Their average knowledge score regarding ergonomics was 2.6, or “fair to good.” Overall, the participants reported good attitude scores, with a total average score of 1 and 2, or “agree to strongly agree.” The findings also indicated that appropriate ergonomics practices were often not implemented, as the average practice score was 1 to 2, or “always to sometimes engaging in bad practice.” The risk factors of being Saudi, being a woman, and having low academic achievement were associated with poor knowledge, attitudes, and practices related to ergonomics among HCWs. Conclusion This study showed that the majority of the participants had fair knowledge and good attitudes toward ergonomics at work while practicing. However, the practice of ergonomics at work was not implemented. It is important to apply ergonomics at work to prevent MSDs; therefore, ergonomic principles should be included in the undergraduate health curriculum for all HCWs, with emphasis on practicing ergonomics in their routine clinical work. ![]()

Abstract
Neck pain is identified as the ache, irritation and discomfort in the area below your head up to third Thoracic vertebrae. It can radiate to shoulders, arms and fingers also. The presenting complaints of cervical patients include headache, stiff neck, stress, muscle pain, fever, and tenderness, radiating pain, weakness in the arm and difficulty in lifting or gripping activities. Patients may also present with numbness, tingling and weakness of the arm. Objective: To determine the prevalence of neck and back pain among gynecologists and obstetrics in different tertiary care hospitals of Lahore. Methods: The cross-sectional study included 310 gynecologist and obstetrics that were recruited using non-probability convenience sampling. The cases of the neck pain were recruited from the obstetrics and gynecology department of different hospitals including: Fatima Memorial Hospital, Shalimar Hospital, Services Hospital, Mayo Hospital and Sir Ganga Ram Hospital, Lahore. Research was completed within six months from 23 October 2021 to 30th April 2022. Results: Among 310 participants, 196 (63.2%) reported neck pain among which; 153 (44.4%) gynecologists reported pain two times per week. Out of total, 306 (98.7%) reported fatigue especially on long days. Results regarding pain area showed that 196 (63.2%) had neck pain, 64 (24.6%) had back pain and 50 (16.1%) had shoulder pain. Results regarding frequency of pain showed that out of 310 (100%), 153 (49.4%) had pain 2 times per week and 105 (33.9%) had pain 0-2 times per month. Conclusions: Prevalence of low back pain was 20.65% whereas prevalence of neck pain in gynecologists was 63.23%. The study suggests that neck pain and fatigue were common in gynecologists and obstetrics. They lack of postural awareness and don’t follow ergonomics principles during surgical procedures.

Abstract
In this report, the authors examine the integration of teaching anatomical science with clinical implications in minimally invasive surgery. The authors hypothesized that implementation of integrated laparoscopic simulation during undergraduate medical education would improve student learning of anatomical structures from in situ, laparoscopic orientations; and subsequently improve student preparation for clinical rotations and clerkships. During the fall of 2020 and 2021, 260 (130 students/year) second year medical students at the University of Nebraska Medical Center participated in a six‐week gastrointestinal curriculum. Following a traditional anatomy dissection experience, students completed a laparoscopic event consisting of narrated laparoscopic videos and hands‐on laparoscopic simulation. To examine the integrated curricular event, outcome measures focused on technical performance using grasping forceps, anatomical knowledge, and perception of the educational innovation. Outcomes were analyzed via timed performance and a pre and post assessment that was designed to assess student anatomical knowledge and perception. Completion of the technical performance assessment ranged from 1 min, 17 s to 6 min. Student knowledge of anatomical structures from in situ, laparoscopic orientations following the laparoscopic simulation sessions was significantly improved (53.3% pre vs 81.0% post), and almost all students (98.9%) agreed that the simulation sessions improved their understanding of laparoscopic anatomy and procedures. This report demonstrates the implementation of a multidisciplinary, integrated simulation that satisfied basic science anatomy teaching objectives, while enhancing student enthusiasm for the content. Future studies will examine the subsequent impact of the innovation on student preparedness for clinical rotations and clerkships.

Abstract
BACKGROUND: Minimally invasive surgery (MIS) has many advantages for patients, however, it places surgeons at risk for Work-related musculoskeletal disorders (WMSD). Recently, the importance of prevention of such injuries and improvement of the ergonomics of the operating room is increasing. OBJECTIVES: To assess the prevalence of WMSD among minimally invasive surgeons in Israel, discuss the contributing factors and the overall awareness for ergonomic training. In addition, a review of the literature on the topic was conducted. METHODS: An online questionnaire was sent to the members of the Israeli Society of Endoscopic Surgery. The results were analyzed and summarized. For literature review, PubMed was used to search for English-language publications related to the issue. RESULTS: Of 83 respondents, the majority (77%) have considerable experience in MIS (more than 10 years). The prevalence of WMSD was 12% before beginning the practice of laparoscopy compared to 78% after 15–20 years of practice. Injury sites included back pain, neck and upper extremity (shoulder pain, tennis elbow and carpal tunnel syndrome) in 41%, 25% and 34% respectively. More than two thirds of responders unaware of possible ergonomic solutions and didn’t consider adopting any appropriate preventive measures. CONCLUSIONS: The incidence of WMSD among MIS surgeons is high and underestimated. There is a desperate need to prevent such morbidity among surgeons by increasing awareness and providing the means to improve their work environment. Surgeons should adhere to ergonomic recommendations for positioning of monitors, table height, posture, foot pedal placement and laparoscopic devices use.

Abstract
UNLABELLED Operation-related musculoskeletal injury (ORMI) among surgeons is a well-described phenomenon. Our study aimed to determine the prevalence of self-reported ORMI among surgeons of various subspecialties and preliminarily investigate the role of gender. METHODS An anonymous survey, querying information pertinent to ORMIs, was distributed online through the American College of Surgeons community membership forum. Nonparametric univariate analysis and a multivariate regression model were conducted. A P value of 0.05 determined significance. RESULTS A total of 624 male and female surgeons responded to the survey, with 50.8% reporting having an injury related to operating. Among the entire cohort, the prevalence of ORMI was significantly higher among female surgeons than male surgeons (P = 0.01), although there was no significant difference among the genders in ORMI prevalence when stratifying by age group (all P > 0.05). CONCLUSION Female surgeons are more likely to report an ORMI, although the impact of confounding variables such as age, operative case volume, and surgical subspecialty remain to be fully elucidated.

Abstract
Musculoskeletal disorders are often found in various types of work, including surgeons. Standing working position is immobile and rigid when performing surgical operations. The equipment used is less ergonomic which is the main parameter. The surgeon profession belongs to the category of the high-risk profession and has the potential to experience musculoskeletal disorders. Surgeons who suffer musculoskeletal disorders sense disease start from mild-to-severe due to the muscles receiving static loads frequently in the long-term. The emergence of musculoskeletal disorders can be caused by working environment conditions and standing position while working, causing injury to joints, vertebral discs, nerves, cartilage, tendons, and muscles. This paper describes in extensive the potential for reducing musculoskeletal problems with the use of a chairless chair for surgeons in carrying out operations. Musculoskeletal problems in surgery and the use of chairless chairs have been further explored to close the existing research gap.

Abstract
In the pelvis, anatomic complexity and difficulty in visualization and access make surgery a formidable task. Surgeons are prone to work-related musculoskeletal injuries from the frequently poor design and flow of their work environment. This is exacerbated by the strain of surgery in the pelvis. These injuries can result in alterations to a surgeons practice, inadvertent patient injury, and even early retirement. Human factors examines the relationships between the surgeon, their instruments and their environment. By bridging physiology, psychology, and ergonomics, human factors allows a better understanding of some of the challenges posed by pelvic surgery. The operative approach involved (open, laparoscopic, robotic, or perineal) plays an important role in the relevant human factors. Improved understanding of ergonomics can mitigate these risks to surgeons. Other human factors approaches such as standardization, use of checklists, and employing resiliency efforts can all improve patient safety in the operating theatre.

Abstract
PURPOSE This study aimed to analyze the relationship between work-related lumbar posture (sitting, standing, walking, alternating posture) and LBP in workers. METHODS This is a retrospective study comprising 529 records of adult workers from a database of a private company. Predominant work-related lumbar posture was classified based on time spent in each posture. A total of 22 personal, occupational, clinical, and psychosocial covariates were evaluated. LBP symptoms in the last 12 months and during the last 7 days were the outcomes of the study. The multivariate analysis model evaluated the independent relationship between the work-related lumbar posture classification and other potential exposure factors with LBP. RESULTS The adjusted logistic regression model indicated that predominant walking reduced the likelihood to report LBP during the last 12 months when compared to standing (OR = 0.54; 95% CI 0.30, 0.99; p = 0.048), but there is no association between work-related postures and recent LBP. The adjusted analyses also revealed an association between LBP during the last 12 months and female sex, blue-collar task, frequently feeling tiredness, pain at any other body region previous 12 months, previous LBP, and monotonous work. Recent LBP was associated with female sex, pain at any other body region last 7 days, and previous LBP. CONCLUSIONS Standing posture increases the likelihood to report LBP during the last 12 months when compared to walking. LBP over previous year and during the previous 7 days was associated with personal and clinical factors.

Abstract
Since its advent, robotic surgery has redefined the operating room experience. It directly addressed and resolved many of the shortcomings of laparoscopic methods while maintaining a minimally invasive approach that brought benefits in cosmesis and healing for patients but also benefits in ergonomics and precision for surgeons. This new platform has brought with it changes in surgical training and education, principally through the utilization of virtual reality. Accurate depictions of human anatomy seen through augmented reality allow the surgeon-in-training to learn, practice and perfect their skills before they operate on their first patient. However, the anatomical knowledge required for minimally invasive surgery (MIS) is distinct from current methods of dissection and prosection that inherently cater towards open surgery with large cuts and unobstructed field. It is integral that robotic surgeons are also equipped with accurate anatomical information, heralding a new era in which anatomists can work alongside those developing virtual reality technology to create anatomical training curricula for MIS. As the field of surgery and medicine in general moves to include more and more technology, it is only fitting that the building blocks of medical education follow suit and rediscover human anatomy in a modern context.

Abstract
OBJECTIVES/HYPOTHESIS Suboptimal ergonomics during endoscopic sinus surgery can lead to considerable physical discomfort and fatigue for the surgeon. The purpose of this pilot study is to objectively evaluate the ergonomic positions of trainee and attending surgeons while performing functional endoscopic sinus surgery (FESS). STUDY DESIGN Pilot prospective trial. METHODS Six surgeons (two attendings and four trainees) performed FESS while wearing 11 inertial measurement units (IMUs) affixed to either side of each major joint. Screen placement was standardized to be 1 m directly in front of the surgeon and on the patient's left, 0-15° declined from the surgeons' eyes. Bed height was standardized such that the workspace was 0 to 10 cm below the elbows. IMU data were analyzed to calculate joint angles. Ideal joint angles (i.e., <10° for neck and trunk) were determined by the validated Rapid Entire Body Assessment tool. Subjects subsequently completed a modified National Aeronautics and Space Administration Task Load Index to assess cognitive and physical burden and pain. Student's t-test was employed to detect differences between groups. RESULTS Trainees adopted positions involving significantly greater neck flexion (9.90° vs. -6.48°, P = .03) and reported significantly higher frustration levels (3.04 vs. 1.33, P = .02) while operating than attendings. For both cohorts, increased operative time was significantly correlated with greater back flexion (r = 0.90, P = .02; r = 0.55, P = .04, respectively). CONCLUSIONS Our data suggest that trainees operate with higher risk neck postures than do attendings. These data indicate high-risk operative postures may be borne of inexperience and present an opportunity for postural interventions at an early stage of training.

Abstract
BACKGROUND The objective of this study was to examine whether an exercise program and standardized operating room positioning protocol (EOPP) would improve surgeon muscle workload and/or surgeon perception of mental/physical workload for nipple-sparing mastectomy (NSM). METHODS This prospective study analyzed muscle workload by EMG of four surgeons performing NSM before and after an EOPP. Surveys were administered assessing surgeon perception of mental/physical workload. EMG data were analyzed using repeated-measures ANOVA, controlling for surgeon, first assistant, duration and difficulty of procedure, left or right side, and sequence of the procedure. RESULTS A total of 56 NSM cases performed by 3 surgeons were analyzed. One surgeon was excluded because of muscle injury and undergoing active physical therapy during the study period. After implementation of the EOPP, the left (P = 0.005) and right (P = 0.020) upper trapezii muscles had a significant decrease in overall ergonomic workload but there was no significant change in overall ergonomic workload for the bilateral cervical erector spinae, anterior deltoid, and lumbar erector spinae muscle groups. When analyzing muscle group exertion by surgeon, there was significant variability in all muscles except the left cervical erector spinae. Following the EOPP, surgeons reported that the procedures were more physically (P = 0.01) and mentally (P = 0.002) demanding and visualization (P = 0.04) was worse. The breast laterality and sequence did not affect muscle exertion. CONCLUSIONS An EOPP decreased the overall ergonomic workload of one muscle group for surgeons performing NSM but did not impact surgeon perception of mental/physical workload. Further investigation is needed to improve surgeon ergonomics.

Lithotomy versus Prone Position for Perianal Surgery: A Randomized Controlled Trial. Ann Coloproctol 2021; 38:117-123. [PMID: 34098632 PMCID: PMC9021856 DOI: 10.3393/ac.2020.12.16] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Accepted: 12/16/2020] [Indexed: 11/09/2022] Open
Abstract
Purpose Studies objectively comparing lithotomy and prone positions regarding surgeon comfort, ergonomics, patient comfort, and position related complications are scarce. Methods The patients posted for surgery of either fistula in ano, hemorrhoids, or were included in this study. Subjective Mental Effort Questionnaire (SMEQ) and Local Experienced Discomfort (LED) scale were used to score the level of mental and physical stress among the operating surgeon, assistants, and the scrub nurse. Other parameters studied were the exposure of the operative site, patient comfort level, and position-related complications. Results Thirty patients were operated in each position. Mean ± standard deviation of jackknife prone vs. lithotomy surgeon SMEQ score (15.6 ± 10.4 vs. 107.0 ± 11.5, P < 0.05) and LED score (1.8 ± 1.5 vs. 6.7 ± 0.5, P < 0.05) were found to be statistically significant. Prone vs. lithotomy assistant SMEQ score (29.1 ± 13.1 vs. 100.6 ± 8.7, P < 0.05) and LED score (4.6 ± 1.1 vs. 7.4 ± 0.8, P < 0.05) were also found to be statistically significant. SMEQ (10.0 ± 0.0 vs. 20.6 ± 2.5, P < 0.05) and LED scores (1.1 ± 0.3 vs. 3.3 ± 0.5, P < 0.05) of scrub nurses and LED scores (2.5 ± 0.5 vs. 6.3 ± 0.7, P < 0.05) of patients were also statistically significant. Exposure of the operative site was significantly better in the prone position (5.0 vs. 2.1, P < 0.05). Conclusion Significantly better SMEQ, LED, and exposure score suggests the superiority of jackknife prone position over the lithotomy in terms of significantly less mental and physical stress to the operating surgeon, assistant, and scrub nurse; better ergonomics, and excellent exposure.

Abstract
Background: In this study, we promote a global approach to occupational risk perception in order to improve occupational health and safety training programs. The study investigates the occupational risk perception of operating room healthcare workers using an Analytic Hierarchy Process approach. Methods: A pilot study was carried out through a cross-sectional survey in a university hospital in Southern Italy. An ad hoc questionnaire was administered to enrolled medical post-graduate students working in the operating room. Results: Fifty medical specialists from seven fields (anaesthetists, digestive system surgeons, general surgeons, maxillofacial surgeons, thoracic surgeons, urologists, and gynaecologists) were questioned about perceived occupational risk by themselves. Biological, ionizing radiation, and chemical risks were the most commonly perceived in order of priority (w = 0.300, 0.219, 0.210). Concerning the biological risk, gynaecologists unexpected perceived this risk as less critical (w = 0.2820) than anaesthesiologists (w = 0.3354), which have the lowest perception of the risk of ionizing radiation (w = 0.1657). Conclusions: Prioritization methods could improve risk perception in healthcare settings and help detect training needs and perform sustainable training programs.

Feasibility of Wearable Display Glasses for Medical Students in the Endoscopy Room. Clin Endosc 2021; 54:694-700. [PMID: 33715343 PMCID: PMC8505181 DOI: 10.5946/ce.2020.246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 12/01/2020] [Indexed: 11/24/2022] Open
Abstract
Background/Aims Several attempts have been made to incorporate smart glasses in the medical field. We applied wearable display glasses to show the position of an observer during endoscopy and compared students’ responses between the conventional and new methods.
Methods We surveyed 28 medical students regarding the use of wearable display devices. The students used wearable display glasses to observe an endoscopic procedure and answered the prepared questionnaire. Their collected responses were analyzed for statistical correlations between each variable.
Results The survey of medical students revealed disadvantages including dizziness (dissatisfied and very dissatisfied: 21.5%) and eye fatigue (25% dissatisfied) and advantages including concentration (satisfied and very satisfied: 57.2%) and securing patient rights (71.4%). The students showed more positive than negative reviews regarding the new devices (32.1% vs. 21.5%).
Conclusions We investigated the advantages and disadvantages of viewing the endoscope image with new wearable display glasses compared to the conventional method using the survey to record user experience. The results revealed relatively positive responses from the medical students in the survey. If the new device compensates for some shortcomings, its use in the endoscopy room will be feasible.

Abstract
Lack of ergonomic training and poor ergonomic habits during the operation leads to musculoskeletal pain and affects the surgeon’s life outside of work. The objective of the study was to evaluate the severity of ergonomic hazards in the surgical profession across a wide range of surgical subspecialties. We conducted intraoperative observations using Rapid Entire Body Assessment (REBA) score system to identify ergonomic hazards. Additionally, each of the ten surgical subspecialty departments were sent an optional 14 question survey which evaluated ergonomic practice, environmental infrastructure, and prior ergonomic training or education. A total of 91 surgeons received intraoperative observation and were evaluated on the REBA scale with a minimum score of 0 (low ergonomic risk <3) and a maximum score of 10 (high ergonomic risk 8–10). And a total of 389 surgeons received the survey and 167 (43%) surgeons responded. Of the respondents, 69.7% reported suffering from musculoskeletal pain. Furthermore, 54.9% of the surgeons reported suffering from the highest level of pain when standing during surgery, while only 14.4% experienced pain when sitting. Importantly, 47.7% stated the pain impacted their work, while 59.5% reported pain affecting quality of life outside of work. Only 23.8% of surgeons had any prior ergonomic education. Both our subjective and objective data suggest that pain and disability induced by poor ergonomics are widespread among the surgical community and confirm that surgeons rarely receive ergonomic training. Intraoperative observational findings identified that the majority of observed surgeons displayed poor posture, particularly a poor cervical angle and use of ergonomic setups, both of which increase ergonomic risk hazards. This data supports the need for a comprehensive ergonomic interventional program for the surgical team and offers potential targets for future intervention.

Practice Longer and Stronger: Maximizing the Physical Well-Being of Surgical Residents with Targeted Ergonomics Training. JOURNAL OF SURGICAL EDUCATION 2020; 77:1024-1027. [PMID: 32763097 DOI: 10.1016/j.jsurg.2020.04.001] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 04/02/2020] [Accepted: 04/04/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVE Pain and disability among surgeons can lead to practice restrictions, early retirement, and physician burnout. This project sought to address the physical well-being of surgical residents by teaching ergonomic principles, a "microbreaks" model, and stretching exercises aimed at targeting the four anatomical areas identified as most problematic for surgeons. DESIGN Three modules, led by physical therapists, were presented to surgical residents over the course of the 2018-2019 academic year. These modules targeted specific problem areas for surgeons according to current literature. A perioperative micro-break model was also presented. Pre- and post-lecture surveys were administered to document pain, applicability of lecture content and effectiveness for use in the operating room (OR), and were reviewed retrospectively. SETTING Jackson Memorial Hospital, DeWitt Daughtry Family Department of Surgery, Division of General Surgery, Miami, Florida RESULTS: A large number of participants reported pain in one or more body part (87%) prior to beginning this ergonomic training and 39% indicated that this pain was performance-limiting. The majority of residents (93%) who attended Module #3 reported that learning the targeted exercises and microbreaks model would help them physically perform better in the OR and, in fact, after practicing these exercises during this Module, 85% of residents reported decreased pain, especially in the areas of the cervical and lumbar spine. CONCLUSIONS Preliminary data indicate that this novel curriculum was perceived as valuable by surgical residents and that practicing these targeted exercises reduced pain, particularly in the neck and lower back. Further research is needed to determine the longitudinal effects of this ergonomics curriculum on surgical resident well-being and whether these exercises will be effective in reducing pain and enhancing performance in the OR setting.

Improving ergonomics in the operating room for orthopaedic surgeons in order to reduce work-related musculoskeletal injuries. Ann Med Surg (Lond) 2020; 56:133-138. [PMID: 32637088 PMCID: PMC7327029 DOI: 10.1016/j.amsu.2020.06.020] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 06/13/2020] [Accepted: 06/14/2020] [Indexed: 02/06/2023] Open
Abstract
Introduction Orthopaedic surgery is characterized by surgical tasks that are physical, repetitive and require some degree of stamina from the surgeon. Occupational injuries are alarmingly common in orthopaedic surgery with two-thirds of all surgeons reporting a work-related musculoskeletal (MSK) injury during their career. One of the leading causes of the high level of MSK injuries among orthopaedic surgeon is lack of ergonomics of the operating room. Implementing an ergonomic process has been shown to be effective in reducing the risk of developing MSK disorders in other high-risk industries. We reviewed well-established and effective ergonomic guidelines from the industrial workplace and determined the pertinent principles that could be transferred to the operating room to help reduce the number and severity of common orthopaedic work-related MSK injuries. Methods We reviewed the ergonomic guidelines, primarily from the Occupational Safety and Health Administration (OSHA), that specifically address minimizing the risk of these work-related injuries and that are transferable to the operating room. In addition, the ergonomic guidelines from the Canadian Center for Occupational Health and Safety (CCOHS), the National Institute for Occupational Safety and Health (NIOSH) and the Centers for Disease Control and Prevention (CDC) were reviewed. Results Many of the guidelines to avoid work-related injuries in industry are transferable to the operating room. The pertinent guidelines clearly indicated how to adjust the height of the operating table, the proper design of hand and power tools and the modifications to the operating room environment that can help prevent injury. These guidelines from industry include maintaining a neutral posture and joint alignment, working with the appropriate hand tools and minimizing the lower extremity fatigue by using the proper footwear and floor mats. Discussion Optimizing the occupational environment and utilizing well-established ergonomic principle from industry is both feasible and practical in the operating room to decrease the incidence of musculoskeletal injuries among this high-risk profession. These guidelines are simple, effective and are easy to implement by orthopaedic surgeons in order to minimize their risk of sustaining a work-related injury.
