Preventing Surgeon Work-Related Musculoskeletal Disorders: A Pilot Study of the Comprehensive Operating Room Ergonomics (CORE) Program.

IMPORTANCE: Work-related musculoskeletal disorders (WMSDs) among surgeons are markedly increasing. Several proposed interventions to reduce WMSDs among surgeons have been studied, but few follow an occupational therapy-oriented approach addressing biomechanical, psychophysical, and psychosocial risk factors. OBJECTIVE: To design, implement, and assess the potential of the Comprehensive Operating Room Ergonomics (CORE) program for surgeons, a holistic evidence-based ergonomics and wellness intervention grounded in occupational therapy principles. DESIGN: Mixed-methods pilot study with the quantitative strand embedded in the qualitative strand. SETTING: University-affiliated hospital. PARTICIPANTS: Six laparoscopic surgeons. OUTCOMES AND MEASURES: CORE program outcomes were assessed using qualitative and quantitative data to indicate changes in posture, physical discomfort, sense of wellness, and operating room (OR) ergonomic performance. The Rapid Upper Limb Assessment (RULA) was used to quantify surgeons' WMSD risk level before and after intervention. RESULTS: There were 12 baseline observations (two for each participant), and two or three post-CORE implementation observations. A statistically significant difference, F(1, 6) = 8.57, p = .03, was found between pre- and post-occupational therapy intervention RULA scores. Thematic analysis of surgeon feedback, which was overwhelmingly positive, identified five themes: postural alignment, areas of commonly reported physical pain or discomfort, setup of the OR environment, surgical ergonomics training, and ergonomics in everyday life. CONCLUSIONS AND RELEVANCE: The CORE program effectively decreased ergonomic risk factors to optimize surgeons' occupational performance in the OR. This study demonstrates a potential solution to how occupational therapists can holistically support surgeons and health care providers who are at risk for WMSDs. Plain-Language Summary: By 2025, a surgeon shortage is expected, partly because of the increase in surgeons' work-related musculoskeletal disorders, which affect their health and job continuity. This pilot study shows that the Comprehensive Operating Room Ergonomics program effectively addresses these problems. The study also serves as a framework for occupational therapy professionals to work with health care providers on ergonomics, benefiting population health. Results suggest that this approach could enhance surgeons' work conditions, supporting the American Occupational Therapy Association's Vision 2025 to improve health and quality of life.

Ergonomics appraisals in operating rooms.

This document presents the ergonomic assessments carried out by Spanish surgeons on the materials used within an operating room. With the objective of disseminating and raising awareness of the importance of ergonomics, this working group has compiled information from a previously conducted survey on musculoskeletal disorders associated with surgical work from the year 2022, obtaining feedback from 131 surgeons from 17 distinct specialties. A noteworthy 80.2 % of surveyed surgeons reported having experienced forced postures during surgery, and 96.9 % believe that their physical discomfort is a result of the posture adopted during operations. Such postures can result in the development of pathologies and may have a direct impact on work performance and even in extreme cases, it can lead to sick leave or early retirement. By providing their insights on electronic devices, surgical furniture, and instrumentation, surgeons can help identify areas for improvement in the practice of their profession.

Operator syndrome: Nursing care and considerations for military Special Operators.

ABSTRACT: Operator syndrome is a common and predictable constellation of interrelated medical and psychiatric conditions and social and functional impairments experienced by special operations forces. Nurses in all settings should be aware of this emerging trend among veterans they encounter in practice so they may identify and intervene using evidence-based approaches and effect a positive outcome.

The implementation study of nurses' work related low back pain prevention and care guideline: A quasi-experimental study.

AIM: To understand the implementation process and outcomes of nurses' work related low back pain (WLBP) prevention and care guideline. BACKGROUND: WLBP is a common occupational injury for clinical nurses. We developed the first evidence-based guideline of nurses' WLBP prevention and care of its kind both at home and abroad, and it is necessary for us to explore its feasibility, appropriateness and effectiveness in practice. METHODS: Based on the model of the integrated Promoting Action on Research Implementation in Health Services, we performed a four-phase implementation study in a tertiary hospital. The study was a non-randomized concurrent controlled trial design，and multilevel measures were examined including implementation outcomes and clinical outcomes. RESULTS: For the implementation outcomes, the tailored recommendations of the guideline were found to be acceptable, appropriate, feasible, and well adopted both at the unit level and the hospital level. The clinical outcomes indicated that, compared with the control unit, nurses of the treatment unit performed better in awareness, knowledge, practice of WLBP prevention and care. CONCLUSIONS: The implementation study supports the successful application of the guideline, which can serve as a valuable evidence-based document to improve back health of nursing personnel.

An integrated approach for economic evaluation of environmental and health costs of occupational diseases in the oil industry.

The health sector is one of the components of development, social welfare and economic growth. The purpose of this study was to develop an economic evaluation model of the environmental and health costs of occupational diseases by hybrid approach. To achieve the study goal, a taxonomy of economic evaluation model of the environmental and health costs of occupational diseases has been developed. The Delphi method was used to identify health and environmental criteria and the analytic network process (ANP) method was used to weigh the sub-criteria. Finally, health and environmental cost were estimated based on the available information. Naft Subspecialty Hospital in Tehran, Iran (NSHT), was selected as the place of case study. In this study, eight and eleven sub-criteria were identified in the health and environmental sector, respectively. The ANP results indicated that the medicine and medical equipment cost criteria with a weight of 0.312 in the Medical sector, and the special and infectious waste cost criteria with a weight of 0.085 in the environmental sector were the most significant cost criteria in NSHT. Furthermore, the parametric model findings indicated that 99.84 and 0.16% of the total costs are associated with health and environmental costs, respectively. The findings indicated that 61.3% of the costs of the health sector were associated with the two sectors of medicine and medical equipment and the cost-of-service personnel, and 91.7% of the costs of the environmental sector are associated with wastewater treatment and the cost of electricity consumption. This study tried to present a quantitative model of the health and environmental costs of NSHT. Implemention of this integrated model can be a practical and effective step in allocating resources and prioritize interventions.

Social determinants and work-related musculoskeletal disorders in Brazil.

This study aimed to analyze the prevalence of work-related musculoskeletal disorders (WMSD) and their association with individual and contextual factors in the Brazilian population. This quantitative cross-sectional study used secondary data from the Brazilian National Health Survey from August 2013 to February 2014. The dependent variable included WMSD, and independent variables were analyzed as individual and contextual factors. WMSD was mostly prevalent in females, individuals aged 43 to 59 years, with chronic physical or mental disorders, reporting frequent sleep disorders, and performing integrative and complementary health practices, physical exercise or sports, and heavy physical activity or housework. Regarding contextual factors, high social classes and proportion of individuals with formal work were associated with a high prevalence of WMSD, whereas a high Gini index was associated with a low prevalence. Thus, a high prevalence of WMSD in the Brazilian population was associated with individual and contextual factors, which should be the target of health professionals for actions of promotion, prevention, and intervention at individual or collective care levels.

Symptoms and Risk Factors of Carpal Tunnel Syndrome among Schoolteachers in Al-Ahsa, Saudi Arabia: A Cross-sectional Study.

CONTEXT: Carpal tunnel syndrome (CTS) is caused by compression of the median nerve as it travels through the carpal tunnel into the wrist. It is the most common peripheral mononeuropathy and accounts for a large proportion of occupational upper extremity disorders. Teaching is an occupation associated with musculoskeletal disorders. AIMS: This study aimed to investigate the prevalence of CTS symptoms and related risk factors among schoolteachers in Al-Ahsa. SETTINGS AND DESIGN: A cross-sectional study was conducted on schoolteachers in Al-Ahsa, Saudi Arabia, during 2023. SUBJECTS AND METHODS: We distributed the Boston Carpal Tunnel Questionnaire to the teachers' groups through social media in the form of an online questionnaire, and we visited schools to encourage participation. STATISTICAL ANALYSIS USED: Data were analyzed using the Statistical Package for the Social Sciences. P < 0.05 was considered statistically significant. RESULTS: Our study included 619 schoolteachers. The syndrome symptoms were present in 71.1% of individuals, and functional disruption was present in 52.7%. The likelihood of exhibiting the symptoms is increased by being female, not participating in sports, having a chronic illness, writing for more than 4 h, and having symptoms in both hands. CONCLUSIONS: We found a comparatively high percentage (71.1%) of the syndrome symptoms among schoolteachers working in Al-Ahsa, Saudi Arabia, which suggests that any signs of CTS in schoolteachers should be evaluated to ensure proper diagnosis and treatment.

Résumé Contexte:Le syndrome du canal carpien (CTS) est causé par la compression du nerf médian lorsqu'il traverse le canal carpien jusqu'au poignet. Il s'agit de la mononeuropathie périphérique la plus courante et représente une grande proportion des troubles professionnels des membres supérieurs. L'enseignement est une profession associée aux troubles musculo-squelettiques.Objectifs:Dans une étude récente menée à Riyad, il y avait un pourcentage relativement élevé (40,0 %) de symptômes du syndrome chez les enseignants.Paramètres et conception:une étude transversale a été menée auprès d'enseignants à Al-Ahsa, en Arabie Saoudite, en 2023.Sujets et méthodes:nous avons distribué le questionnaire du canal carpien de Boston aux groupes d'enseignants via les médias sociaux sous la forme d'un questionnaire en ligne., et nous avons visité les écoles pour encourager la participation.Analyse statistique utilisée:Les données ont été analysées à l'aide du progiciel statistique pour les sciences sociales. P < 0,05 était considéré comme statistiquement significatif.Résultats:Notre étude a porté sur 619 enseignants. Les symptômes du syndrome étaient présents chez 71,1 % des individus et des troubles fonctionnels étaient présents chez 52,7 %. La probabilité de présenter ces symptômes est augmentée par le fait d'être une femme, de ne pas faire de sport, d'avoir une maladie chronique, d'écrire pendant plus de 4 heures et d'avoir des symptômes dans les deux mains.Conclusions:Nous avons trouvé un pourcentage relativement élevé (71,1 %) de symptômes du syndrome chez les enseignants travaillant à Al-Ahsa, en Arabie Saoudite, ce qui suggère que tout signe de SCC chez les enseignants doit être évalué pour garantir un diagnostic et un traitement appropriés.

Research progress on the pathogenesis and prediction of pneumoconiosis among coal miners.

Pneumoconiosis is the most common occupational disease among coal miners, which is a lung disease caused by long-term inhalation of coal dust and retention in the lungs. The early stage of this disease is highly insidious, and pulmonary fibrosis may occur in the middle and late stages, leading to an increase in patient pain index and mortality rate. Currently, there is a lack of effective treatment methods. The pathogenesis of pneumoconiosis is complex and has many influencing factors. Although the characteristics of coal dust have been considered the main cause of different mechanisms of pneumoconiosis, the effects of coal dust composition, particle size and shape, and coal dust concentration on the pathogenesis of pneumoconiosis have not been systematically elucidated. Meanwhile, considering the irreversibility of pneumoconiosis progression, early prediction for pneumoconiosis patients is particularly important. However, there is no early prediction standard for pneumoconiosis among coal miners. This review summarizes the relevant research on the pathogenesis and prediction of pneumoconiosis in coal miners in recent years. Firstly, the pathogenesis of coal worker pneumoconiosis and silicosis was discussed, and the impact of coal dust characteristics on pneumoconiosis was analyzed. Then, the early diagnostic methods for pneumoconiosis have been systematically introduced, with a focus on image collaborative computer-aided diagnosis analysis and biomarker detection. Finally, the challenge of early screening technology for miners with pneumoconiosis was proposed.

Therapeutic Interventions for Prevention of Musculoskeletal Pain Among Orthopedic Surgeons.

Orthopedic surgery is a physically demanding specialty. The factors contributing to musculoskeletal injury among surgeons often stem from positioning the patient, using non-ergonomic instruments, maintaining static postures, and performing repetitive movements. This article focuses on exercise techniques intended to combat the most common problematic static postures held during procedures. Each exercise explained in this article is organized into "preop," "intraop," and "postop" components. Preop includes strengthening movements, intraop provides postural recommendations, and postop focuses on mobilization and recovery. This article aims for efficient body conditioning, targeting the muscular posterior chain and supporting elements. [Orthopedics. 2024;47(4):e214-e216.].

[Mortality in an Italian factory producing tetraethyl lead]. / Mortalità alla SLOI di Trento, un'azienda che produceva piombo tetraetile.

The Società Lavorazioni Organiche Inorganiche (SLOI) in Trento (North-Eastern Italy) produced tetraethyl lead from 1941 to 1978, when it was closed following an explosion, luckily with no fatalities. Working conditions were very bad. During the 1960s, 325 acute lead intoxications were reported and over 100 workers were hospitalized for neurological conditions attributable to tetraethyl lead. At least 12 SLOI workers were hospitalized in the mental asylum (psychiatric wards).The present work describes the first formal epidemiological study ever carried out on SLOI workers. In the absence of any original SLOI employee registers, a list of 1,742 workers hired since factory startup was assembled using the files of the Italian National Social Security Agency (digitalized in 1974 and perused manually by one of the Authors for the previous period). To date, follow-up for mortality has been completed for the 580 male employees at work in 1961 or hired subsequently and who worked at SLOI for at least 12 months. Twenty-two (3.8%) were lost to follow-up. Mortality in this sub-cohort was compared with that of the population of the province of Trento, gathered since 1986 by the Institute of Statistics of the Trento Province. Excluding deaths occurring at age 90+ years, during the 1986-2016 period, deaths in the SLOI sub-cohort were 295 vs 229.0 deaths expected from age- and period-specific rates in the reference population (standardazied mortality ratio 1.29; 95%CI 1.15-1.44). In the absence of individual data, the possible contribution to the mortality excess by non-occupational risk factors cannot be estimated. Identification of causes of death is underway.

[Second Report on Italian Sea Workers: Activities and risk factors]. / Secondo rapporto sui lavoratori marittimi: attività e fattori di rischio.

This is a summary of the results of a research work, born from a collaboration between multiple Italian bodies and published by the Italian Workers' Compensation Authority (Inail) in March 2024: Second report on maritime workers. Activities and risk factors of sea workers.To disseminate the contents, the work offers a global overview of safety and health in the sector: with an analysis of accidents in the sector (which also involves some remarks on the event reporting form), workers' risk perception is examined and occupational diseases monitored through the MalProf system, managed by the Inail Research Sector and the local health authorities. Finally, an in-depth study is dedicated to exposure to asbestos on ships.

Zinc fever in a painter and varnisher: a case report.

BACKGROUND: Zinc fever is well described in medical literature, particularly in workers after handling zinc-containing materials at high temperatures e.g., in the welding of hot-dip galvanized steel sheets. It is not known whether zinc fever also occurs at low temperatures. CASE PRESENTATION: We present the case of a 33-year-old Caucasian atopic painter and varnisher with work-related dyspnea, sweating, as well as multiple occurrences of fever. He was sent to Institute for Prevention and Occupational medicine of the German Social Accident Insurance, Institute of the Ruhr-Universität Bochum (IPA) for the evaluation of isocyanate asthma, but an inhalative challenge with hexamethylene diisocyanate was negative. Since symptoms were closely related to the use of zinc coatings at room temperature without adequate protective measures, the diagnosis of zinc fever was made. After exposure cessation the worker immediately became symptom-free. The work as painter and varnisher may be associated with various exposures to hazardous substances. Besides solvents, epoxy compounds and isocyanates, which can cause obstructive respiratory diseases; additionally, zinc-containing agents should be considered as health hazards. CONCLUSIONS: This case demonstrates that zinc fever may occur also after application of zinc coatings by spray painting at low temperatures.

Low back pain frequency and the related risk factors in nurses and caregivers.

OBJECTIVES: The objective of this study is to investigate the frequency of low back pain and the relationship between low back pain and personal and occupational risk factors in hospital employees. METHODS: The study sample consisted of 270 nurses and 189 caregivers working in a university hospital. Demographic characteristics, low back pain history, and low back pain risk factors were queried by self-report questionnaires. The Biering-Sorensen Test was used to evaluate the endurance of trunk extensor muscles. Also, the Oswestry Disability Index (ODI) and Hospital Anxiety and Depression Scale (HADS) were used. RESULTS: Of the hospital employees included in the study, 56.5% had low back pain in the last month, and 81.9% had a his-tory of low back pain. The frequency of low back pain was significantly higher among those who work in a stressful working environment, stand for extended periods, lift patients or heavy subjects without using a lifting device, and transfer patients alone. In addition, it was determined that those who exercise regularly and are satisfied with their job had significantly less low back pain (p<0.05). The mean Biering-Sorensen test difference between the two groups was statistically significant (p<0.001). There was a significant difference between the groups with and without low back pain in terms of HADS-Anxiety and HADS-Depression subscale scores. CONCLUSION: The study findings indicated that being a hospital worker is a risk factor for low back pain, and the decrease in the strength and endurance of the lower back muscles increases the risk of low back pain.

Evaluating the categorisation of interventions in individual working practice aimed at preventing work-related musculoskeletal disorders: An international experts consultation.

In a previous scoping review, eight categories of interventions in individual work practice were defined. The aim of the present study is to evaluate the relevance and completeness of these eight categories and to increase the clarity of the nomenclature and definitions of each category. An international expert consultation has been carried out for this purpose. Thirty-eight experts from 13 countries participated. Data collection was conducted using a survey design comprising structured questions. Consensus was reached if 75% of the experts answered 'Strongly agree' or 'Agree' on a 5-point Likert scale. For the topic 'Relevance', there was consensus for six of the eight categories (range 78%-86%), the exceptions were the categories: 'Exercising' (72%) and 'Professional manners' (64%). With regard to the topic 'Nomenclature', consensus was reached for six categories and for the topic 'Definition' this was five categories. The present definitions have been improved based on the expert recommendations. With respect to the topic 'Completeness': although a limited number of suggestions were given, this did not lead to one or more categories being added to the existing eight categories. The final 'Nomenclature' for the categories is: 'Variation', 'Professional behaviour', 'Motoric skills', 'Vocational working techniques', 'Physical workplace', 'Physical training', 'Assistive devices and tools' and 'Task content and task organisation'. This expert consultation has provided a solid basis for endorsing the categorisation of interventions in IWP and is an important step in building a framework to develop and evaluate interventions in IWP.

Carcinogenicity of asbestos-free talc and talcum powder: A systematic review of the epidemiological evidence after the 2006 monograph of the International Agency for Research on Cancer.

BACKGROUND: in 2006, the International Agency for Research on Cancer (IARC) concluded that the evidence of carcinogenicity for asbestos-free talc was inadequate (group 3), whereas perineal use of talcum powder was classified as possibly carcinogenic (group 2B). OBJECTIVES: to assess whether later studies provide more solid information on the carcinogenic risk from asbestos-free talc and talcum powder and a better characterization of exposure. DESIGN: systematic review. METHODS: cohort studies of talc miners and millers exposed to asbestos-free talc, as well as cohort and case-control studies reporting cancer risk in talc powder consumers published from 2006 onwards were identified through PubMed and reference lists. Pooled analyses were included, but not reviews and meta-analyses. In the case of repeatedly reported studies, the article with the longest follow-up or the largest number of observed cases was selected for data abstraction. Notice was taken of studies which were both reported individually and included in pooled analyses. RESULTS: publications meeting inclusion criteria were: 2 cohort studies on talc miners and millers, 10 cohort studies on talcum powder users (4 of which estimated ovarian cancer risk), and 14 case-control studies (13 on ovarian and 1 on endometrial cancer) on the risk from talcum powder use. No excess cancer mortality has been reported among asbestos-free talc miners and millers. Case-control studies consistently led to estimates of ovarian cancer excesses associated with the use of perineal talcum powder (odds ratios up to 1.5). Most studies quantifying exposure also provided evidence of a dose-response relationship. Individual cohort studies estimated hazard ratios (HR) just above 1. In an analysis of pooled cohorts for a total of 3,112 cases, the HR for women with patent reproductive tract was 1.13 (95%CI 1.01-1.26) with a correlation between HR and frequency of use (p for trend 0.03). In all cohort studies, the perineal use of talcum powder was measured only once in the early phases of follow-up, thus producing an inaccurate measure of cumulative exposure. Results of epidemiological studies regarding cancer risk in other organs are limited and inconsistent. CONCLUSIONS: epidemiological studies updated or published after IARC 2006 evaluation indicate that: no increase in cancer risk is apparent among miners and millers of asbestos-free talc; risk for ovarian cancer increases following the perineal use of commercial talcum powder. A correlation between indicators of quantity of use and cancer risk is suggested by a number of studies. The composition of talcum powders considered in such studies is not known.

Are we straining to succeed? Prevalence of work-related musculoskeletal disorders among dentists in teaching hospitals.

OBJECTIVE: To determine the prevalence of work-related musculoskeletal disorders among dentists. METHODS: The cross-sectional study was conducted in Islamabad, Pakistan, from January to March 2023 after approval from the ethics review committee of the Islamic International Dental Hospital, Islamabad, and comprised dentists associated with 4 major dental teaching hospitals in the city. Data was collected using a self-administered questionnaire adapted from literature. Prevalence of work-related musculoskeletal disorders was explored along with its association with variables, like age, gender, experience, designation and history of injury. Data was analysed using SPSS 26. RESULTS: Of the 250 forms distributed, 188 (75.2%) were returned duly filled, while the remaining participants either did not respond or partially filled out the forms. Among the respondents, 64(34%) were males and 124(66%) were females, and the overall prevalence of work-related musculoskeletal disorders was 172(91.5%). There was no significant difference among the variables based on anatomic site-specific data, except the designation variable, with individuals having a history of injury to neck (p=0.027) or shoulder (p=0.001) and those designated as professor (p=0.040) were significantly at risk of developing pain due to work-related musculoskeletal disorders. CONCLUSIONS: A significantly high number of dentists were found to have some form of work-related musculoskeletal disorder.
