Work-Related Upper Limb Symptoms in Hand-Intensive Health Care Occupations: A Cross-Sectional Study With a Health and Safety Perspective.

Research with physical therapists reveals high rates of work-related musculoskeletal injuries, especially low back pain, with early career onset. Less focus has been given to upper limb disorders (ULDs) in these professionals, who frequently perform repetitive arm/hand and precision finger motions during work. The objective was to estimate prevalence of body-site-specific upper limb (UL) symptoms and diagnosed ULDs in Irish chartered physical therapists, physiotherapists, and athletic therapists, with adjustment for leisure time injury, and document first onset of specific UL symptoms. The design was a cross-sectional survey (N=347) using random sampling (physiotherapists in private practice), proportionate cluster sampling (hospital-based physiotherapists), and all-population sampling (physical therapists and athletic therapists). The methods used were a postal questionnaire with annual, current, and incapacitating UL symptoms (neck, shoulders, elbows, wrists, fingers, thumbs) (Nordic Questionnaire); symptom onset; diagnosed UL disorders; and sociodemographics; prevalence with 95% CIs, and adjusted prevalence (general linear modeling). Adjusted annual prevalence of UL symptoms in at least 1 body site was 78.1% (95% CI = 71.4-82.2), and of incapacitating symptoms was 21.0% (95% CI = 16.4-27.0). Shoulder (53.2%, 95% CI = 47.9-58.7), neck (49.4%, 95% CI = 44.2-55.0), and thumbs (46.1%, 95% CI = 40.7-51.5) were mostly affected. Hospital-based therapists had a significantly higher prevalence of incapacitating symptoms compared with others (35.7% vs 23.3%). Respondents totaling 28.2% had at least 1 lifetime diagnosis of ULD, most commonly shoulder tendonitis (12.5%, 95% CI = 8.4-15.3) and overuse syndrome (11.8%, 95% CI = 8.4-15.3). First onset was mostly after 5 years working as a therapist; however, this differed by anatomical site. A cross-sectional study design limited interpretation of symptoms as work-related causes. The high prevalence of ULD and symptoms warrants attention from occupational health and safety personnel. Training in injury prevention and risk assessment should be provided during education and as part of continuing education.

Assessing risk through composite FMEA with pairwise matrix and Markov chains

PurposeFailure mode and effect analysis (FMEA) is an analysis technique for identifying and eliminating known and/or potential failures and problems from products, processes or systems. Notwithstanding its diffusion, traditional FMEA has several limitations. Lately, scientific research has been focused on improving said limitations, yet the process is still ongoing. The purpose of this paper is to support developments in this area.Design/methodology/approachThe paper improves the conventional FMEA by using the method of pairwise comparison to establish the relative importance of the input factors in risk priority number calculation, and Markov chains to calculate risk distributions in the long term.FindingsThe functioning and usefulness of the proposed methodology is demonstrated through an application to the construction industry, one of the world’s biggest industrial sectors, dogged by a high rate of work-related injuries and casualties.Originality/valueHaving demonstrated the applicability of the novel methodology to a real domain, the paper contributes to the process of overcoming traditional FMEA limitations.

Occupational Health and Safety Vulnerability of Recent Immigrants and Refugees.

Recent immigrants and refugees have higher rates of work-related injuries and illnesses compared to Canadian-born workers. As a result, they are often labelled as vulnerable workers. This study explored the factors that contribute to occupational health and safety (OHS) vulnerability of recent immigrants and refugees with a focus on modifiable factors such as exposure to hazards and access to workplace protections, awareness of OHS and worker rights, and empowerment to act on those rights. Eighteen focus groups were conducted with 110 recent immigrants and refugees about their experiences looking for work and in their first jobs in Canada. A thematic content analysis was used to organize the data and to identify and report themes. The jobs described by participants typically involved poor working conditions and exposure to hazards without adequate workplace protections. Most participants had limited knowledge of OHS and employment rights and tended to not voice safety concerns to employers. Understanding OHS vulnerability from the lens of workplace context can help identify modifiable conditions that affect the risk of injury and illness among recent immigrants and refugees. Safe work integration depends on providing these workers with information about their rights, adequate job training, and opportunities for participating in injury prevention.

Capital Market Frictions and Human Capital Investment: Evidence from Workplace Safety around Regulation SHO

Using Regulation SHO as natural experiment, we find that work-related injury and illness rates increase significantly at treated firms relative to the control group. The effect is more pronounced for firms in more competitive industries, firms in which labor has low negotiating power with management, and those that are more financially constrained or with poor corporate governance. Further, this effect is not explained by salient firm performance characteristics and is stronger for firms whose stock returns are less sensitive to injury rates. Overall, the results shed light on how capital market frictions impact firms’ investment in workplace safety.

Health effects of wind turbines in working environments - a scoping review.

Objectives The wind industry is a growing economic sector, yet there is no overview summarizing all exposures emanating from wind turbines throughout their life cycle that may pose a risk for workers` health. The aim of this scoping review was to survey and outline the body of evidence around the health effects of wind turbines in working environments in order to identify research gaps and to highlight the need for further research. Methods A scoping review with a transparent and systematic procedure was conducted using a comprehensive search strategy. Two independent reviewers conducted most of the review steps. Results Twenty articles of varying methodical quality were included. Our findings of the included studies indicate that substances used in rotor blade manufacture (epoxy resin and styrene) cause skin disorders, and respectively, respiratory ailments and eye complaints; exposure to onshore wind turbine noise leads to annoyance, sleep disorders, and lowered general health; finally working in the wind industry is associated with a considerable accident rate, resulting in injuries or fatalities. Conclusions Due to the different work activities during the life cycle of a wind turbine and the distinction between on- and offshore work, there are no specific overall health effects of working in the wind sector. Previous research has primarily focused on evaluating the effects of working in the wind industry on skin disorders, accidents, and noise consequences. There is a need for further research, particularly in studying the effect of wind turbine work on psychological and musculoskeletal disorders, work-related injury and accident rates, and health outcomes in later life cycle phases.

A pilot study to precisely quantify forces applied by sonographers while scanning: A step toward reducing ergonomic injury.

There is a significantly high rate of work-related musculsokeletal injuries in sonography professionals. To date, assessment of risk factors for work- related injuries in sonographers has been based primarily on surveys, subjective reports, and observational methods. There is a need to develop quantitative techniques to better understand risk factors and develop preventive interventions. We pilot tested a high-resolution force-measuring probe capable of precisely measuring forces applied through the transducer by sonographers and used this novel direct measurement technique to evaluate forces during abdominal imaging. Twelve sonographers with varied experience, ranging from 1-33 years, performed routine abdominal scans on 10 healthy volunteers who had varied body mass indices (BMI). Imaging was conducted using the force-measuring probe, which provided real-time measurement of forces, and angles. Data were compared by sonographer years of experience and subject BMI. In total, 47 abdominal examinations were performed as part of this study, and all images met standards for clinical diagnostic quality. The mean contact force applied across all exams was 8.2±4.3 Newtons (N) (range: 1.2-36.5 N). For subjects in the high BMI group (BMI>25, n = 4) the mean force was 10.5 N (range: 8.9-13.2 N) compared to 7.9 N (range: 5.9-10.9 N) for subjects with normal BMI (BMI = 18.5-25, n = 6). Similarly, the mean maximum force applied for subjects with high BMI (25.3 N) was significantly higher than force applied for subjects with normal BMI (17.4 N). No significant difference was noted in the amount of force applied by sonographers with more than 5 years of experience (n = 6) at 8.2 N (Range: 5.1-10.0 N) compared to less experienced sonographers (n = 6), whose forces averaged 8.1 N (Range: 5.8-10.0 N). It is feasible to directly measure forces applied by sonographers using a high-resolution force measurement system. Forces applied during abdominal imaging vary widely, are significantly higher when scanning subjects with high BMI, and are not related to sonographer years of experience. This force measurement system has the potential to provide an additional quantitative data point to explore the impact of applied forces on sonographer related musculoskeletal injury, particularly in conjunction with various body positions, exam types and force durations.

Determinants of occupational injury for US home health aides reporting one or more work-related injuries.

Home health aides (HHAs) work in a high-risk industry and experience high rates of work-related injury that have been significantly associated with reduction in workers and organisational productivity, quality and performance. The main objective of the study was to examine how worker environment and ergonomic factors affect HHA risk for reporting occupational injuries. We used cross-sectional analysis of data from the 2007 National Home Health and Hospice Aide Survey (NHHAS). The study sample consisted of a nationally represented sample of home health aides (n=3.377) with a 76.6% response rate. We used two scales 1 : a Work Environment Scale and 2 an Ergonomic Scale. Univariate and bivariate analyses were conducted to describe HHA work-related injury across individual, job and organisational factors. To measure scale reliability, Cronbach's alphas were calculated. Multivariable logistic regression was used to determine predictors of reported occupational injury. In terms of Work Environment Scale, the injury risk was decreased in HHAs who did not consistently care for the same patients (OR=0.96, 95% CI: 0.53 to 1.73). In terms of Ergonomic Scale, the injury risk was decreased only in HHAs who reported not needing any other devices for job safety (OR=0.30, 95% (CI): 0.15 to 0.61). No other Work Environment or Ergonomic Scale factors were associated with HHAs' risk of injury. This study has great implications on a subcategory of the workforce that has a limited amount of published work and studies, as of today, as well as an anticipated large demand for them.

Work-Related Accidents and Sharp Injuries in Paramedics-Illustrated with an Example of a Multi-Specialist Hospital, Located in Central Poland.

(1) Background: An analysis of work-related accidents in paramedics in Poland by presenting the model and trend of accidents, accident rates and by identifying causes and results of accidents; (2) Methods: A retrospective analysis of medical documentation regarding work-related accidents in a multi-specialist hospital, located in central Poland, in the period 2005–2015. The study group included paramedics who had an accident while being on duty; (3) Results: According to hospital records, 88 paramedics were involved in 390 accidents and 265 injuries caused by sharp instruments. The annual accident rate was 5.34/100 employed paramedics. Most of the accidents occurred at night. The most common reason for the accident was careless behaviour of the paramedic, which resulted in joint sprains and dislocations. Injuries accounted for a huge portion of the total number of events. As many as 45% of injuries were not officially recorded; (4) Conclusion: High rates of work-related accidents and injuries caused by sharp instruments in paramedics are a serious public health problem. Further studies should be conducted in order to identify risk factors of accidents, particularly injuries, and to implement preventative programmes, aiming to minimise rates of occupational hazards for paramedics.

Associations of Organizational Safety Practices and Culture With Physical Workload, Perceptions About Work, and Work-Related Injury and Symptoms Among Hospital Nurses.

The study aim was to examine the relationships of organizational safety practices with nurses' perceptions about job and risk and experiences of work-related injury and symptoms. Nursing professions report high rates of work-related injuries. Organizational safety practices have been linked to workers' safety outcomes and perceptions about work. This study analyzed data from a random sample of 280 California RNs in a cross-sectional statewide survey. Data were collected by both postal and online surveys. Higher perceptions of organizational safety practices (safety climate, ergonomic practices, people-oriented culture) were significantly associated with lower physical workload, lower job strain, higher job satisfaction, lower risk perception, and lower work-related injury and symptom experiences. Ergonomic practices and people-oriented culture were associated with less intention of leaving job. Organizational safety practices may play a pivotal role in improving positive perceptions about jobs, reducing injury risks, and promoting nurse retention.

OCCUPATIONAL HAZARDS IN CONSTRUCTION INDUSTRY: CASE STUDIES FROM HOUSING AND CONSTRUCTION WORKERS AT ADDIS ABABA, ETHIOPIA

The status of occupational injuries in workplaces in general is ill defined in Ethiopia. Pocket studies indicate that occupational injury due to an unsafe working environment is increasing. Construction industries are growing industries region wise that has higher rate of work-related injuries. Knowing the associated factors of work-related injuries can be a critical step for improving the working condition of workers in the sector.
 Objective: This mini research aimed to evaluate occupational hazards and to describe factors affecting its happening among construction workers’ in Addis Ababa housing and construction project sites.
 Institutional based cross-sectional study design was employed to assess occupational injuries among randomly selected construction workers from June 30 –July 20, 2014. A structured questionnaire based interviews, work environment observation were used to collect the data.
 The response rate of this study was 82.7%. The majority of respondents were male which account 74.7% and 60 (96.8%) respondents were not using personal protective devices all the time while they are on duty. Out of the total participants, 67.7% of the workers experienced occupational injuries at least once in the last 12 months. Moreover, the three leading cause of injuries were puncture (21.0%) followed by hand injury (11.3%), and back pain (9.7%).
 Increased rate of work related injury in construction workers was observed and implementation of basic occupational health and safety services is required together with regular supervision to ensure and promote work place safety. So Preventive measures concerning functional occupational health and safety programs are essential to safeguard the health and safety condition of workforce in construction industries.

Work-Related Unintentional Injuries Associated With Hurricane Sandy in New Jersey.

We aimed to evaluate the occurrence of work-related injuries after Hurricane Sandy potentially related to response and recovery. Emergency and hospital discharges (patients aged 18-65 years) with a diagnosis of unintentional injury were obtained from the New Jersey Department of Health. Work-related injuries were identified as those with a workers' compensation payer or other work-related codes. Counties were categorized as high-, medium-, or low-impact areas. Poisson regression analysis was used to compare the rate of work-related injury the year following Sandy landfall with the 3 previous years. Total work-related injuries declined the week immediately after Sandy (rate ratio [RR]: 0.85; 95% confidence interval [CI]: 0.69-1.05) and no overall increase was found in the year after Hurricane Sandy. However, high-impact counties showed an elevated risk of work-related injuries in the first and third quarters after Hurricane Sandy among men, especially for blacks and Hispanics. The greatest excesses occurred in the third quarter after the storm, May to July, for falls (RR: 1.30; 95% CI: 1.08-1.57), cut/pierce injuries (RR: 1.24; 95% CI: 1.09-1.40), struck-by injuries (RR: 1.17; 95% CI: 1.02-1.34), and overexertion (RR: 1.26; 95% CI: 1.10-1.44). Hospital data suggested an increase in injuries associated with rebuilding and recovery rather than with initial response. Future efforts aimed at prevention should evaluate the mechanisms and circumstances of injury in more detail. (Disaster Med Public Health Preparedness. 2016;10:394-404).

An analysis of permanent work disability among construction sheet metal workers.

Causes of permanent work disability in the sheet metal industry are not well characterized. Pension records were used to compare causes of disability among sheet metal workers and the U.S. working population. Subgroup analysis examined the major causes of sheet metal worker disability. Musculoskeletal disorders (MSDs), circulatory disease, and injuries were leading causes of sheet metal worker disability (47.2%, 13.7%, 10.9% of awards, respectively). Award distribution differed from the U.S. working population (P < 0.0001); MSDs and injuries accounted for higher proportions of sheet metal worker awards, particularly at spine, shoulder, and knee. Higher proportions of awards caused by MSD or injury among sheet metal workers may reflect higher rates of work-related injuries and MSDs, a high likelihood of disability with construction work given the same impairment, or higher prevalence of other conditions in the general population. Prevention requires task-specific ergonomic innovations and proven participatory interventions.

Experience Rating and Work-Related Health and Safety

In the area of Workers Compensation Insurance schemes, experience rating (ER) is a common incentive tool, in many countries. Premiums paid by firms are experience rated, which should encourage them to improve working conditions and reduce work-related injuries and disabilities. Using sectorial data for industry and construction sectors in 2005, this article provides empirical insights into the influence of ER on work-related health and safety in the context of the French jurisdiction. We examine the relationship between firm premium rate variations and adverse working conditions indicators, controlling for observables, assuming the hypothesis of an asymmetric firm response to premium increases and decreases. The results are consistent with the hypothesis that ER is a lever to improve working conditions and reduce work-related injury rates. Further investigation is needed to understand the influence of ER on firm behavior.

Push Forces on Vinyl and Carpet for Conventional Wheeled and Motor-Driven Floor-Based Lifts among Direct Care Staff in Long-Term Care

In response to high rates of work-related musculoskeletal injury (MSI) in long-term care (LTC), decision makers have implemented minimal-lift policies to reduce strain arising from resident transferring, often advocating the use of lifting devices. Floor-based lifts, in particular, are widely used in LTC, even though users are known to experience potentially injurious forces when pushing overweight or obese residents on carpet (Marras, Knapik &amp; Ferguson, 2009). Motivated by this, a European manufacturer has developed a motor-driven, floor-based lift to assist users with resident transferring (esense Rise, Active4Care, Enschede, NL). Despite the motor-driven lift’s promise as a strategy for improved workplace safety, no research has been published examining its ability to reduce external hand forces, or perceptions of ease among users, during pushing. Therefore, we compared external hand forces and subjective ratings of perceived ease when straight-line pushing a motor-driven versus conventional (manual wheeled) floor-based lift, under conditions of low (vinyl) and high (carpet) rolling resistance, and while transporting passengers of average (67 kg) and ninetieth percentile (90 kg) resident weight. We recruited fourteen female direct care staff from a partner LTC site in British Columbia, Canada. We collected external hand force data using a piezoelectric, triaxial load cell (model 9074C, Kistler, Winterthur, Switzerland), custom mounted between existing lift handholds and a cylindrical handlebar. We also collected information on exposure (frequency, distance) to pushing in LTC by questionnaire, and calculated participant-specific tolerance limits for initial and sustained forces using Snook and Ciriello’s (1991) Hazard Analysis Tool. We observed a significant interaction between lift type and floor surface on initial (p &lt; 0.001) and sustained (p &lt; 0.001) forces. On vinyl, the motor-driven lift required, on average, 35 N (34%) less initial force (p &lt; 0.001) and 14 N (27%) less sustained force (p &lt; 0.001) than the conventional lift, regardless of resident weight. On carpet, we observed larger differences in forces between lifts, with the motor-driven lift requiring, on average, 64 N (36%) less initial force (p &lt; 0.001) and 51 N (52%) less sustained force (p &lt; 0.001) than the conventional lift, regardless of resident weight. Furthermore, there was an interaction between lift type and floor surface on subjective ratings of perceived ease of pushing (p &lt; 0.001). On vinyl, subjective ratings did not differ between lifts (p = 0.32), with the majority of participants rating their ease of pushing as ‘very easy’ when pushing 90 kg passengers in both the conventional lift (n = 8, 57.1%) and the motor- driven lift (n = 12, 85.7%). On carpet, however, ratings were, on average, 1.8-points lower with the motor- driven lift (mean = 1.7; ‘somewhat easy’) than the conventional lift (mean = 3.5; ‘somewhat difficult’), independent of resident weight (p &lt; 0.001). No conditions involving the motor-driven lift imposed forces above tolerable limits, while three of fourteen (21.4%) direct care staff exerted forces above tolerable limits when using the conventional lift on carpet only. Our results did not demonstrate a clear need for a motor-driven lift to mitigate the biomechanical demands of linear pushing on vinyl, as no participants’ force values approached tolerable limits for either lift on vinyl. Subjective ratings were also no different between lifts on vinyl. We did, however, demonstrate that motor-driven lifts reduce the biomechanical demands associated with pushing floor-based lifts on carpet. This insight can be used to inform evidence-based practices to improve worker safety during resident transferring, which could lead to reductions in both the incidence and severity of work-related MSI in LTC.

Stretch breaks in the work setting improve flexibility and grip strength and reduce musculoskeletal complaints

AbstractThis study investigated the effect of a stretch break program (SBP) on the flexibility, strength and musculoskeletal complaints of storage (SW) and administrative (AW) sector workers. Twenty-six male workers were randomly selected: 16 workers from the storage sector and ten workers from the administrative sector. We applied the Physical Activity Questionnaire and Musculoskeletal Questionnaire and evaluated flexibility and grip strength before and after 6 months of the SBP. The SPB decreased the SW group members' complaints of paresthesias and numbness in the upper body and total body. The SPB reduced the AW group members' complaints of paresthesias and numbness in the upper body. Furthermore, the SPB improved cervical, trunk and left shoulder flexibility in the SW group and improved cervical and shoulder flexibility and grip strength in the AW group. The SBP contribute to improve flexibility and musculoskeletal complaints in the regions that are affected by higher rates of work-related injuries.

Social identity in the construction industry: implications for safety perception and behaviour

The construction industry has one of the highest frequency levels and rates of work-related injuries, yet the evidence for successful attempts to reduce injuries is generally lacking. The motivational and (safety) behavioural implications of social identification and social categorization among construction labourer work crews were investigated to ascertain how their interactions are affected by the social structure and organization of work. Semi-structured group interviews and mini interviews during work were carried out with 13 concrete work crews (totalling 53 persons) at five large construction sites. The organization of work fosters social identification within a crew, resulting in distancing from and social categorization of site management. Social identification influences safety behaviour in the crews, where worksite safety rules may meet resistance. Future safety initiatives at large construction sites should take into account the dynamics of social identification and categorization in the implementation of safety measures, e.g. by creating an alternative organization of work, thus making it easier for a work crew to identify themselves with the site management. Site/crew managers should consider how safety can become a salient and valued group norm by altering the social structure at the sites and/or fostering dual social identity.

Empowering employers in work-related injuries prevention: A pragmatic trial

ObjectivesInterest in work-related injury prevention is increasing, but evaluating workplace safety interventions poses a critical challenge on methodological approaches. The hypothesis has been made that safety training programmes targeting management executives could improve worksite safety. This study aimed to investigate the correlation between a training programme for employers and the rate of occupational injuries in a sample of wood processing industries. MethodsOne hundred forty worksites were randomly assigned to the intervention or the control arms of the study. The intervention consisted in a 6h training course for employers focusing on the benefits, feasibility, and cost-saving connected to safety in the workplace. The primary outcome was the rate of injuries assessed by means of the incidence rate difference (point estimates and 95% confidence interval) in the two arms of the study at the end of the follow-up period. ResultsThe rate of work-related injuries decreased in both groups, with an incidence rate after intervention of 3.35 and 3.91 (×10,000 working hours), respectively, in the study and control arms, for a difference of −0.56 (95% CI −1.56–0.45). The reduction in injuries from baseline to the end of the follow-up was comparable to that noted in other geographical areas. ConclusionsThe intervention programme did not appear to have any effect on the decrease in the rate of work-related injuries. We can hypothesize that the training course did not modify employers’ behavior to affect the incidence of occupational injuries.
