An ergonomic assessment of using laterally-tilting operating room tables and friction reducing devices for patient lateral transfers

The compatibility of exoskeletons in perioperative environments and workflows: an analysis of surgical team members' perspectives and workflow simulation

Surgical team members in perioperative environments experience high physical demands. Interventions such as exoskeletons, external wearable devices that support users, have the potential to reduce these work-related physical demands. However, barriers such as workplace environment and task compatibility may limit exoskeleton implementation. This study gathered the perspectives of 33 surgical team members: 12 surgeons, four surgical residents, seven operating room (OR) nurses, seven surgical technicians (STs), two central processing technicians (CPTs), and one infection control nurse to understand their workplace compatibility. Team members were introduced to passive exoskeletons via demonstrations, after which surgical staff (OR nurses, STs, and CPTs) were led through a simulated workflow walkthrough where they completed tasks representative of their workday. Five themes emerged from the interviews (workflow, user needs, hindrances, motivation for intervention, and acceptance) with unique subthemes for each population. Overall, exoskeletons were largely compatible with the duties and workflow of surgical team members.

Composite Medical Tabletops Made of CFRP with Different Cross-Sections: Numerical Analysis and Laboratory Testing

This paper presents the results of laboratory tests of CFRP (carbon fiber-reinforced polymer) laminates, which allowed the development of numerical material models. The obtained data were used in a further stage to perform numerical simulations of four variants of medical tabletops, differing, among other features, in the shape of the cross-section. Maximum deflections and effort in the composite material were analyzed. The final step was to perform a laboratory test for one of the tabletop versions, the results of which confirmed the correctness of the numerical calculations. This work is aimed at both researchers and designers involved in the practical application of fiber-reinforced polymer matrix composites.

Efficacy of Interventions in Reducing the Risks of Work-Related Musculoskeletal Disorders Among Healthcare Workers: A Systematic Review and Meta-Analysis

BACKGROUND

Work-related musculoskeletal disorders (WMSDs) are prevalent among healthcare professionals, including nurses, therapists, doctors, and paramedics, due to the potential injuries incurred during patient transfer and handling. This review aimed to assess the effectiveness of existing interventions in reducing the risks of WMSDs in this population.

METHODS

Four databases including PubMed/MEDLINE, Web of Science, Scopus, and ScienceDirect were searched to identify randomized and nonrandomized controlled trials, as well as studies with pre-post design. Two reviewers independently extracted data and assessed the quality of the included studies using the Effective Public Health Practice Project criteria. A meta-analysis was performed to obtain quantitative results.

RESULTS

A total of 40 studies were included in the review. Among the interventions, motorized assistive devices showed the most significant relative reduction in WMSD risks (p < .0000; standardized mean difference [SMD] = -3.32, 95% confidence interval [CI] = [-4.53, -2.12]), followed by combined interventions of cognitive and exercise (p < .0001; SMD = -0.62, 95% CI = [-0.91, -0.33]), combined intervention of cognitive and assistive device intervention (p = .02; SMD = -0.77, 95% CI = [-1.42, -0.12]), nonmotorized assistive device (p = .02; SMD = -0.63, 95% CI = [-1.15, -0.12]), cognitive intervention (p < .0001; SMD = -0.62, 95% CI = [-0.91, -0.33]), and physical exercise (p = .06; SMD = -0.16, 95% CI = [-0.32, 0.00]) intervention.

CONCLUSION

The overall evidence indicates that interventions have a significant effect in reducing the risk of WMSDs among healthcare workers, with motorized assistive devices showing the most promising results. The findings from this review can provide valuable guidance for hospital administrators, policymakers, and other experts in implementing effective strategies to prevent WMSDs among healthcare professionals.

Effectiveness of Safe Patient Handling Equipment and Techniques: A Review of Biomechanical Studies

OBJECTIVE

This review aimed to evaluate all studies that have evaluated the biomechanical effects when using assistive devices.

INTRODUCTION

The physical demands of patient handling activities are well known. One safety strategy for the reduction of the physical risks is use of assistive devices.

METHOD

The search process identified articles published in English-speaking journals through Google Scholar, Medline, and ISI Web of Science. The included 56 studies contained a biomechanical assessment of a patient handling activity with assistive devices.

RESULTS

The biomechanical effects included four groups: changes in body posture (spinal, other joints), subjective assessment (force, effort, discomfort), measured force (hand force, ground reaction force, spine force, joint torque), and physiological measures. The evidence showed caregivers benefited from using lift hoists, air-assisted devices, and to a lesser extent friction reducing devices for lateral transfers and repositioning, while floor and ceiling lifts were most effective for patient transfers. Some gaps were noted in the evidence and other handling tasks such as sit-to-stand, turning patient in bed, limb lifting, and repositioning and some more high hazard activities like supporting people with limited balance and those that fall need to be investigated with respect to biomechanical outcomes.

CONCLUSION

There is a growing level of biomechanical evidence to support the use of assistive devices for many patient-handling tasks, but the benefits of equipment use in some transfers remain uninvestigated.

PRACTICAL APPLICATION

Evidence indicates the best way to lift patients safely is with floor or ceiling lifts, and air-assisted devices for lateral and repositioning tasks.

The effects of patient transfer devices on the risk of work-related musculoskeletal disorders (WMSDs): a systematic review

Objectives. This study aimed to evaluate the efficacy of patient transfer assistive devices in reducing the risk of work-related musculoskeletal disorders (WMSDs) among nurses. Methods. PubMed, Scopus, Google Scholar and the Cochrane Database of Systematic Reviews were searched to identify studies with a quantitative assessment of the efficacy of patient transfer assistive devices on the incidence and injury claims of WMSDs as compared to the manual lifting of patients. A health impact analysis of the pre-post intervention of assistive device implementation was performed. The percentage of the reduction of forces, incidence of WMSDs, number of missed workdays and injury compensation claims were calculated, pooled and presented as boxplots. Results. A total of 25 studies met the inclusion criteria. The best post-intervention outcomes of assistive devices deployment in the healthcare setting included a reduction in WMSD incidence by 59.8%, missed workdays by 90.0% and workers' compensation claims by 95.0%. Additionally, hand force declined by 71% (p < 0.05) and 70% (p < 0.05) with the use of air-assisted devices and ceiling lifts respectively. Conclusions. Overall, the evidence suggests that patient transfer assistive devices, notably ceiling lifts and air-assisted devices, are effective in reducing the risk of WMSDs among nurses.

A Multidisciplinary Focus Review of Musculoskeletal Disorders Among Operating Room Personnel

Musculoskeletal disorder is one of the major health issues and is recognized as the second most common occupational disease. The aim of the present study was to investigate the different aspects of musculoskeletal disorders in operating room personnel. The present study was conducted to evaluate the prevalence of MSDs among operating room personnel, in January 2020. In this study, the authors explored 30 articles from five databases including Medline/PubMed, ProQuest, Scopus, Embase, and Google Scholar. The present study found that physical, psychological, and demographic characteristics including age, gender, work experience, and smoking were the most important risk factors for these disorders. Musculoskeletal disorders were also prevalent in different areas of the body, with the highest prevalence being in the lumbar region. In addition, regular exercise and physical activity, the use of stretching and gentle exercise to reduce physical pressure, regard to the principles of ergonomics in the workplace, regular physical examinations, and awareness of the risk factors for these disorders. Therefore, operating room officials need to promote operating room programs focused on reducing musculoskeletal disorders and increase the awareness of the personnel about the risk factors by conducting training courses.
