Lower extremity musculoskeletal disorders in nurses: A narrative literature review

The humanistic and economic burden of work-related musculoskeletal pain: a cross-sectional survey of workers in the United Kingdom

OBJECTIVE

The aim of this study was to evaluate the impact of work-related musculoskeletal (MSK) lower body pain on health-related quality of life (HRQoL) and work productivity in a large sample of workers in the United Kingdom, as well as evaluating the potential economic impact of MSK pain.

METHODS

Participants with self-reported work-related MSK pain were recruited from an online panel maintained by a third party (Qualtrics LLC). Participants completed three validated instruments online: the Brief Pain Inventory (BPI), the Assessment of Quality of Life Instrument (AQoL-4D), and the 6-item Work Productivity and Activity Impairment Questionnaire (WPAI). Sociodemographic details, work patterns and healthcare resource utilisation were also reported. One-way analysis of variance (ANOVA) and t-tests were used to explore differences between variables. Linear regression was applied to determine the impact of work-related MSK pain on HRQoL.

RESULTS

All 1035 recruited participants completed the survey (57.4% female; mean age 43.4 years). Participants reported spending all (25.2%) or most (53%) of their time at work on their feet. Mean pain severity was 4.63 (standard deviation: 2.07); mean pain interference was 4.37 (2.49). There was a linear relationship between length of shift, time on feet and pain. Mean AQoL-4D scores were 0.609 (0.254). A mean of 4.12 h was lost per week due to pain. Absenteeism (last 7 days) was 9.5% (20.7%), and presenteeism 33.3% (24.9%). An average 1.55 visits were made to family practitioners (total cost: £19,866) and 1 hospital visit (£37,320) due to work-related MSK pain.

CONCLUSION

This study demonstrated that work-related lower body pain has a significant impact in terms of individual HRQoL and as an economic societal burden.

Prevalence and Associated Factors of Ankle-Foot Pain Among Nurses Working in Surgical Units of Comprehensive Specialized Hospitals in Amhara Regional State, Northwest Ethiopia, 2022

Background

Ankle-foot pain is a serious public health concern among nurses and has a significant impact on the quality of the health care service delivery system. However, little is known about the prevalence and factors associated with ankle-foot pain among nurses working in surgical units in Ethiopia.

Purpose

The study aimed to assess the prevalence and associated factors of ankle-foot pain among nurses working in surgical units of comprehensive specialized hospitals in Amhara regional state, Northwest Ethiopia, 2022.

Participants and Methods

An institution-based cross-sectional study was conducted among 409 nurses working in surgical units of comprehensive specialized hospitals, from May 15 to June 7, 2022. A simple random sampling technique was employed. Data were collected by five BSc nurses using a structured self-administered questionnaire. The collected data were entered into Epi-data version 4.6 and exported to SPSS version 23 for analysis. The descriptive statistics and bivariable and multivariable logistic regression analyses were computed. Finally, variables were declared as statistically significant at P < 0.05 using the odds ratio and 95% CI.

Results

The prevalence of ankle-foot pain among nurses working in surgical units was 51.8% (95% CI = 46.9-57.5). More than 10 years of working experience [AOR = 3.48, 95% CI = 1.35-8.92], working 48 or more hours per week [AOR = 2.69, 95% CI = 1.27-6.00], prolonged standing [AOR = 5.72, 95% CI = 3.20-10.25], high physical job demand [AOR = 2.41, 95% CI = 1.53-3.80], and low job control [AOR = 2.34, 95% CI = 1.47-3.71] had statistically significant association with ankle-foot pain.

Conclusion

This study found that ankle-foot pain was common among nurses working in surgical units. Having more years of work experience, working more hours per week, prolonged standing, high physical job demand, and low job control were statistically associated with ankle-foot pain.

Musculoskeletal pain in health professionals at the end of their studies and 1 year after entry into the profession: a multi-center longitudinal questionnaire study from Switzerland

BACKGROUND

Musculoskeletal pain, especially back pain, is common among health care professionals (HP). For prevention purposes, it is important to know whether HP develop their symptoms before or after entering the health care workforce. Cross-sectional studies among HP cannot answer this question. This follow-up study measures the prevalence and individual course of musculoskeletal pain among full-time HP students at the end of their studies and one year after entering the health care workforce.

METHOD

Self-reported one-year prevalence for low back pain, neck/shoulder pain, pain in arms/hands, and pain in legs/feet was collected at two timepoints from 1046 participating HP using an online questionnaire. Participants were asked whether their musculoskeletal pain was related to study or work conditions. Generalized estimating equation (GEE) models of the binomial family with log link were used to estimate adjusted prevalence and corresponding normal based 95% confidence intervals were derived using the bootstrap method with 1000 replications.

RESULTS

The prevalence of low back pain as well as neck and shoulder pain was very high at baseline and follow-up in all full-time students and later HP. Prevalence for pain in arms/hands, legs/feet was low and there were significant differences between the professions. HP clearly associated their low back pain and neck/shoulder pain with study and work conditions; HP strongly associated pain in arms/hands, legs/feet only with work conditions.

CONCLUSION

Many HP suffer from back/neck/shoulder pain already as students before starting their professional career. The prevention of back/neck/shoulder pain must be part of the education of all health professions at universities. As an example of best practice, universities should incorporate ergonomic measures and exercises into the daily routine of training health professionals. The effects of physically demanding professional tasks on the upper and lower extremities need to be investigated in further studies to take preventive measures.

Foot and Ankle Disorders in Nurses Exposed to Prolonged Standing Environments: A Scoping Review

BACKGROUND

Prolonged standing environments constitute an occupational risk factor for nurses, particularly for developing foot and ankle disorders. The definitions and potential relationship to hours spent walking or standing are poorly understood. This scoping review aimed to synthesize the main disorders found on nurses' ankles and feet, their prevalence, the influence of hours spent walking or standing, and gender differences.

METHODS

This review followed a previously published protocol. Primary and secondary studies were retrieved from relevant databases from December 2020 to March 2021. Potential articles were collated to Mendeley, and two independent reviewers assessed the title and abstracts. Studies meeting inclusion criteria were included. Two researchers retrieved and reviewed the full text of these studies independently. A predetermined extraction tool was used to retrieve relevant data, summarized in a tabular and narrative format.

FINDINGS

The most common disorder was pain, followed by numbness, burning feet, bunions, structural deformities, and calluses. Prevalence differed among studies, depending on settings and specific local policies. Discussion: Various foot and ankle disorders and related variables have been found, with clear gaps that may be addressed in the future.

CONCLUSION/APPLICATIONS TO PRACTICE:

Few studies have focused on nurses' foot and ankle disorders. Mapping signs and symptoms may contribute to the future development of preventive interventions for nurses' workplaces.

Nurses’ experience with chronic foot pain and their job-the national science foundation foot health survey

Background

Chronic foot pain (CFP) impacts nurses' ability to provide care at the bedside. Treatment options for CFP were insufficient to address foot pain for nurses who stand or walk for prolonged periods while providing care to patients.

Aims

This study aimed to explore nurses' experience with CFP, current treatment options for foot pain, and the impact of foot pain on nurses' job performance.

Methods

This is secondary data from Individual interviews (n = 122) involving open-ended questions. Data were collected between April 2019-September 2020 while attending the National Science Foundation (NSF) I-Corps program comprising faculty and students among others in the United States. Multiple linear regression and multinomial/binary logistic regressions were conducted to assess what factors were associated with the pain and pain relief solutions.

Results

Nurses who worked at the bedside predominantly switched jobs and reported higher levels of foot pain than those who did not switch jobs (β = 0.19, p = .044). Longer working hours (β = 0.35, p < .001) were associated with higher levels of pain. Nurses who worked longer time were more likely to purchase new work shoes and socks (OR = 1.177, p = .025) to alleviate foot pain than changing shoes only.

Conclusions

Most nurses expressed interest in new products to relieve their CFP. Innovations are urgently needed to address CFP. Future longitudinal studies are required to further elucidate appropriate preventative strategies to prevent and treat CFP in nurses.

The Correlation of Frequency of Work-Related Disorders with Type of Work among Polish Employees

Musculoskeletal disorders have a significant negative impact on the quality of life of the population. These conditions, as well as other work-related disorders, generate costs associated with treatment and work absence, which makes it a growing problem in industrialized countries. Available data from studies on individual populations of workers indicate a higher incidence of certain symptoms in these groups. Due to the lack of studies on the general population, we aimed to perform the preliminary study evaluating the occurrence of pain and work-related conditions depending on the type of occupational work among Polish employees to identify further possible areas for research. Data was collected using an electronic self-administered questionnaire, which was distributed in groups bringing together various professionals. The data obtained from 379 participants have been analyzed and divided according to performed work into sedentary, forced posture, standing, physical and requiring physical activity. Our study reveals a correlation between the frequency of work-related disorders and type of work performed in the Polish population. A significant correlation between the type of occupational work and prevalence of ankle, knee and shoulder pain, as well as heavy legs or upper limb paresthesia was found. According to our findings, female employees may be more vulnerable to lower limb symptoms. A place of residence also seems to affect the prevalence of upper back pain and heavy legs. The analysis also showed a correlation between the occurrence of hip, knee and ankle pain and the level of education of the participants. Surprisingly, lower extremity paresthesia was significantly more common among participants undertaking additional physical activity, compared to non-physically active respondents.

Development and Effectiveness Testing of a Novel 3D-Printed Multi-Material Orthosis in Nurses with Plantar Foot Pain

Plantar foot pain is one of the most common musculoskeletal conditions affecting the foot. It is regularly experienced by the population with occupations that require prolonged standing hours, especially in nurses. The etiology of plantar foot pain remains unclear, but it is likely to be multi-factorial, with many associated risk factors including increased hours of standing. Orthoses and insoles are often recommended to plantar foot pain patients, however with minimal scientific advancements and limited customizations. In this study, a novel 3D-printed multi-material customized foot orthosis was developed, and its effectiveness on plantar foot pain reduction and functional ability improvement was studied in the nursing population. A total of thirty-six subjects were recruited and were randomized into two groups. The experimental group received the novel 3D-printed multi-material customized foot orthosis, whereas the control group received the standard-of-care (or traditional) intervention. Pre-test and the post-test scores of pains, functional ability and plantar pressure were observed using SPSS software. Improvements were observed in both of the groups; however, better improvements were seen in the experimental group. Overall, the novel 3D printing-based customized foot orthosis showed significant efficacy in reducing plantar foot pain and pressure, and also in increasing functional ability in the nursing population as compared to the traditional method.

Correlation between standing posture during work and low back and lower limb pain among cleaners and caregivers of older adults

ABSTRACT Maintaining a standing posture during work has been associated with musculoskeletal symptoms. Few studies, however, assess the standing time using objective measures. Thus, this study aimed to verify whether standing time at work is associated with lower back and lower limb pain in the last seven days and last 12 months in caregivers of older adults and cleaners. This is a cross-sectional study. Standing time at work was quantified using inclinometers attached to the workers’ thigh and spine. Musculoskeletal symptoms were assessed using the Nordic Musculoskeletal Questionnaire. Data were analyzed using the point-biserial correlation coefficient (rpb) between standing time at work and the presence of musculoskeletal symptoms. The analyses were performed using the SPSS software, adopting 5% significance level. Workers spend most of their time standing still (41.3%) or walking (39.3%). The presence of symptoms in the lower back was positively correlated with standing time (rpb=0.52; p<0.05). Walking time was negatively correlated with symptoms at the hip in the last 12 months (rpb=−0.53; p<0.05) and running time with symptoms at the hip, in the last seven days, (rpb=−0.43; p<0.05) and the lower back (rpb=−0.43; p<0.05). Longer standing time was correlated with the presence of symptoms in the lower back. Meanwhile, less time walking and running were correlated with the presence of musculoskeletal symptoms in the hips and lower back.

Correlação entre a postura em pé durante o trabalho e dor na coluna lombar e nos membros inferiores em trabalhadoras da limpeza e cuidadoras de idosos

RESUMO A postura em pé durante o trabalho tem sido associada a sintomas musculoesqueléticos. Entretanto, há poucos estudos que avaliam o tempo em pé utilizando medidas objetivas. Assim, o objetivo deste estudo foi verificar se o tempo em pé no trabalho está associado com dor na coluna lombar e nos membros inferiores nos últimos sete dias e 12 meses em cuidadoras de idosos e trabalhadoras da limpeza. Trata-se de estudo transversal, em que o tempo em pé no trabalho foi quantificado por meio de inclinômetros fixados na coxa e na coluna vertebral, e os sintomas musculoesqueléticos foram avaliados por meio do Questionário Nórdico de Sintomas Osteomusculares. Os dados foram analisados por meio da correlação ponto bisserial (rpb) entre o tempo em pé no trabalho e a presença de sintomas musculoesqueléticos. As análises foram realizadas por meio do software SPSS e o nível de significância adotado foi de 5%. Verificou-se que as trabalhadoras passam a maior parte do tempo em pé paradas (41,3%) ou andando (39,3%). Houve correlação positiva entre a presença de sintoma na lombar e o tempo em pé (rpb=0,52; p<0,05) e correlação negativa entre o tempo andando e sintomas no quadril (rpb=−0,53; p<0,05) nos últimos 12 meses e o tempo correndo e sintomas no quadril (rpb=−0,43; p<0,05) e na coluna lombar (rpb=−0,43; p<0,05) nos últimos sete dias. O maior tempo em pé foi correlacionado com a presença de sintomas na lombar; enquanto o menor tempo andando e correndo foram correlacionados com a presença de sintomas no quadril e na coluna lombar.

Baropodometric Assessment of the Podiatric Profile of Nursing Students in Clinical Settings: A Study Protocol

Introduction

Nursing students are exposed to increased risks of developing foot and ankle disorders due to prolonged standing and walking positions during clinical settings. This can lead to high dropout rates from nursing degree, thus contributing to a future shortage in nursing professionals. This protocol aims to develop a study to understand the influence of prolonged standing and walking positions on nursing students' foot health, and specifically to study the relationship between the podiatric profile (regional force and pressure exerted on the foot) and related signs and symptoms.

Methods and Analysis

A prospective observational cohort study will be conducted with 194 nursing students. Participants will be asked to walk through a baropodometric platform before and after a 5-month clinical training session. Assessment will focus on the change in podiatric profile, namely foot posture and foot function, at 5 months, and changes in foot health at 5 months. The study will start in January 2022 and it's expected to end by June 2022.

Discussion

The study aims to perform an innovative assessment of nursing students' podiatric profile, which will allow for a comprehensive description of foot/ankle changes and their relationship with prolonged standing and walking contexts.

Ethics and Dissemination

The study was approved by The Ethical Committee of the Health Sciences Research Unit: Nursing (UICISA: E), of the Nursing School of Coimbra (ESEnfC), with the approval code nr. P799_07_2021. The study was also recorded in ClinicalTrials.gov on the number NCT05197166. Findings will be used to publish articles in peer-review scientific journals and oral communications and posters at scientific meetings.

What sociodemographic and work characteristics are associated with musculoskeletal complaints in nursing students? A cross-sectional analysis of repeated measurements

Musculoskeletal complaints (MSCs) arise during nursing education. We examined cross-sectional associations between self-reported MSCs and both sociodemographic and workplace characteristics in different clinical placement settings. We included two observations among three cohorts of third-year Dutch nursing students (total N = 711) of the undergraduate nursing program of Rotterdam University of Applied Sciences. Questionnaire data on sociodemographic, physical and psychosocial work characteristics, and MSCs were used. Generalized estimating equation analysis for repeated measurements with backward elimination was used to examine associations with MSCs. In total, 79% of students experienced MSCs. Female sex (OR 0.37, 95% CI 0.22-0.62), lifting and bending (OR 1.01, 95% CI 1.00-1.03), physical job demands (OR 2.33, 95% CI 1.68-3.22) and need for recovery (OR 1.02, 95% CI 1.01-1.03), were statistically significantly associated with overall MSCs. Models for regional complaints are also presented in this article. Nursing school and clinical placement staff should consider these factors when dealing with nursing students with MSCs.

Prevalence of Work-Related Musculoskeletal Disorders: Psychological and Physical Risk Factors

Purpose—This study aimed to estimate the prevalence and risk factors of MSD pain in various anatomical regions among nurses. Method—A cross-sectional study involving a self-administered questionnaire by registered nurses with clinical experience. Data was collected using convenience sampling after obtaining informed consent. The results were drawn from a total of 300 nurses. Results—The nurses presented with occasional mental exhaustion (44.3%) and often physical exhaustion (44.0%). Almost all (97.3%) the nurses complained of having work-related pain during the last 12 months. Body parts with the most pain were the lower back (86.7%), ankles (86.7%), neck (86.0%), shoulders (85.0%), lower legs (84.7%) and upper back (84.3%). The pain frequency was rated as occasional pain for the neck and upper back, pain was often felt for the rest of the parts. Nurses complained of severe pain in the lower back (19.7%), right shoulder (29.7%) and left shoulder (30.3%). The frequency of having musculoskeletal symptoms in any body region was increased with age, lower education level, female gender, high BMI, job tenure and lifestyle. Conclusions—Nurses’ WRMSD complaints should be taken seriously to curb further risk and musculoskeletal hazards.

Foot Disorders in Nursing Standing Environments: A Scoping Review Protocol

Musculoskeletal disorders can be significantly disabling, particularly those related to work, when the underlying mechanisms and clinical variables are not well known and understood. Nurses usually remain in standing positions or walk for long periods, thus increasing the risk for the development of musculoskeletal disorders, particularly on the foot, such as plantar fasciitis or edema. This type of disorders is a major cause of sickness, absence from work, and also dropout ratios among nursing students, which contributes to the shortage of nursing professionals. This review will address foot disorders that arise from prolonged standing in nursing professionals and describe the main clinical parameters characterizing them, with exclusions for other health professions or disorders with other identified causes. English, French, Portuguese, and Spanish published studies from 1970 to the current year will be considered. The review will follow the JBI methodology, mainly though the PCC mnemonic, and the reporting guidelines for Scoping Reviews. The search will include main databases and relevant scientific repositories. Two independent reviewers will analyze the titles, abstracts, and full texts. A tool developed by the research team will aid in the data collection.

A Rasch analysis of the self-administered Foot Health Assessment Instrument (S-FHAI)

Background

Reliable and valid measurement is the foundation of evidence-based practice. The self-administered Foot Health Assessment Instrument (S-FHAI) was recently developed to measure patients’ evaluations of their own foot health. Evidence regarding the psychometric properties of the S-FHAI is limited. The aim of this study was to investigate those properties by using a Rasch analysis.

Methods

This methodological study analysed secondary data that was collected from nurses (n = 411) in 2015. The psychometric properties of the S-FHAI were evaluated using the Rasch model. Unidimensionality was analysed first, followed by item functioning, person misfit and differential item functioning (DIF).

Results

The S-FHAI demonstrated evidence of unidimensionality, with an acceptable item fit according to the Rasch model. Person fit and person separation were low, however, indicating restricted separation among different respondents. Item separation was high, demonstrating clear discrimination between the items. No DIF was detected in relation to gender, but significant DIF was demonstrated in relation to age for 6 of the 25 items.

Conclusions

The S-FHAI has potential for use in investigating self-reported foot health. The Rasch analysis revealed that the psychometric properties of the instrument were acceptable, although some issues should be addressed to improve the scale. In future, it may be beneficial to analyse the sensitivity of the items and to test the S-FHAI in more diverse patient populations.

Ankle and Foot Pain and Associated Factors Among Nurses at Ayder Comprehensive Specialized Hospital, Mekelle, Ethiopia: Cross-Sectional Study

Background

Ankle–foot pain is a significant public health problem in nurse professionals and has great burdens to the individuals, healthcare systems, and community at large. However, there is limited evidence on the prevalence of ankle–foot pain and its associated factors among nurses in Ethiopia. Thus, the finding of this study will help to address health problems resulting from ankle–foot pain among nurses.

Purpose

The aim of this study was to determine the prevalence and associated factors of ankle–s–foot pain among nurse working in Ayder Comprehensive Specialized Hospital, Tigray, Ethiopia.

Patients and Methods

An institutional-based cross-sectional study was conducted on a total of 366 nurses, and a simple random sampling technique was used to recruit study participants. Data were collected by using a self-administered adapted standardized Nordic questionnaire. Descriptive statistics and a bivariate logistic regression model were done to identify factors associated with ankle–foot pain. Those variables with a P-value less than 0.05 with 95% CI in multivariate model were taken as statistically significant. Finally, AOR with 95% confidence interval at a P-value of <0.05 was reported.

Results

The prevalence of self-reported ankle–foot pain among nurses was 43.7% (95% CI=38.5–49.1). Older age (AOR=7.669, 95% CI=2.316−25.390), low shoe comfort (AOR=4.215, 95% CI=2.031–8.745), multiple foot conditions (AOR=6.102 95% CI=1.959–19.008), working night shifts (AOR=2.047, 95% CI=1.098−3.816), high physical demand (AOR=3.487, 95% CI=1.988–6.116), and nurses working in the intensive care unit (AOR=2.402, 95% CI=1.219–4.732) showed a statistically significant association with ankle–foot pain.

Conclusion

This study indicated that the prevalence of ankle–foot pain is commonly reported among nurses working in Ayder Comprehensive Specialized Hospital. Therefore, awareness and prevention of ankle and foot pain in nurses should be prioritized to reducing risk factors. Nurses should give attention to comfortable footwear, and further longitudinal research is recommended.

Associations of objectively measured total duration and maximum bout length of standing at work with lower-extremity pain intensity: a 2-year follow-up of construction and healthcare workers

Background

Musculoskeletal disorders are among the major reasons for years lived with disability. Approximately one third of the European working population report lower-extremity discomfort and many attribute these discomforts to work-related factors. Employees in the healthcare and construction sectors reports high levels of lower-extremity pain and commonly relate the pain to their profession. These workers spend a large part of their workday standing. Periods of prolonged standing is suggested to increase lower-extremity symptoms, but this cannot be concluded on, since limited evidence is available from longitudinal studies using objective measures. This study aimed to determine possible associations between objectively measured total duration and maximum bout length of static- and dynamic standing at work and lower-extremity pain intensity (LEPi) among Norwegian construction- and healthcare workers.

Methods

One-hundred and twenty-three construction and healthcare workers wore two accelerometers for up to four consecutive days, to establish standing behavior at baseline. The participants reported LEPi (Likert scale 0–9) for the preceding 4 weeks at baseline and after 6, 12, 18, and 24 months. We investigated associations between standing at work and average and change in LEPi using linear mixed models with significance level p ≤ 0.05.

Results

Total duration of static- and dynamic standing showed weak associations with average LEPi, for the total sample and for construction workers. Maximum bout of static- and dynamic standing was associated with average LEPi in construction workers, but not in healthcare workers. Furthermore, we found no associations between standing and change in LEPi over the 2-year follow-up in any of our analyses.

Conclusions

This study indicate that objectively measured standing is associated with average LEPi over 2-years follow-up in construction workers, and that maximal bout of standing have a stronger association to LEPi than total duration. For every 10 min added to the maximal length of continuous standing during an average workday, we found approximately one unit increase in pain on a 0–9 scale. The lack of significant findings in analyses on healthcare workers suggest that the association between standing and LEPi depend on work-tasks, gender and/or other sector-specific factors.

A framework for studying risk factors for lower extremity musculoskeletal discomfort in nurses

Lower extremity musculoskeletal discomfort (MSD) is prevalent, but understudied, in nurses. A comprehensive, theoretical, aetiological model of lower extremity work-related MSD in hospital in-patient staff nurses was developed through a review of the literature to provide a framework for aetiological and intervention research. The framework informed the design of a survey of 502 hospital staff nurses. Symptom prevalence ranged from 32% in hip/thigh to 59% in ankle/foot regions. Logistic regression modelling using survey data showed that different work and personal factors were associated with discomfort in different regions of the lower extremity. Individual factors (e.g. older age, higher BMI or having any foot condition), physical factors (e.g. higher frequency of patient handling), psychosocial factors (e.g. lower job satisfaction) were associated with discomfort in one or more parts of the lower extremity. Future research should target these factors for intervention, to attempt to reduce occurrence of lower extremity discomfort in nurses. Practitioner Summary: Practitioners may find useful the illustrated, theoretical aetiological model of factors that could influence the prevalence of lower extremity discomfort in nurses. The model could guide conversations with nurses and observational analyses of nursing work. The model and survey results may provide ideas for intervention exploration.

Association between Health Problems and Turnover Intention in Shift Work Nurses: Health Problem Clustering

Shift work nurses experience multiple health problems due to irregular shifts and heavy job demands. However, the comorbidity patterns of nurses’ health problems and the association between health problems and turnover intention have rarely been studied. This study aimed to identify and cluster shift work nurses’ health problems and to reveal the associations between health problems and turnover intention. In this cross-sectional study, we analyzed data from 500 nurses who worked at two tertiary hospitals in Seoul, South Korea. Data, including turnover intention and nine types of health issues, were collected between March 2018 and April 2019. Hierarchical clustering and multiple ordinal logistic regressions were used for the data analysis. Among the participants, 22.2% expressed turnover intention and the mean number of health problems was 4.5 (range 0–9). Using multiple ordinal logistic regressions analysis, it was shown that sleep disturbance, depression, fatigue, a gastrointestinal disorder, and leg or foot discomfort as a single health problem significantly increased turnover intention. After clustering the health problems, four clusters were identified and only the neuropsychological cluster—sleep disturbance, fatigue, and depression—significantly increased turnover intention. We propose that health problems within the neuropsychological cluster must receive close attention and be addressed simultaneously to decrease nurse’s turnover intentions.

The Effects of Multifaceted Ergonomic Interventions on Musculoskeletal Complaints in Intensive Care Units

Working at intensive care units (ICUs) is considered a risk factor for developing musculoskeletal complaints (MSC). This study was conducted between January 2017 and June 2019 in two ICUs of a university hospital. It was designed as a pre- and post-assessment of the intervention group (IG) (N = 27) compared with a control group (CG) (N = 23) to determine the effects of a multifaceted ergonomics intervention program in reducing MSC. The IG (N: 35) received a multifaceted ergonomic intervention program, which was implemented by an ERGO team over an 18 month period. Four ergonomic interventions were planned as follows: individual level interventions such as training; stretching exercises and motivation meetings; administrative intervention such as a daily 10 min stretching exercises break; engineering interventions such as lifting and usage of auxiliary devices. The CG (N:29) did not receive any intervention. Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was used to assess MSC in both groups. At the start of the intervention, both groups were similar concerning the number of visits to doctors due to MSC, the number of sick leave days, and total CMDQ scores (p > 0.05 for all). Two factor repeated ANOVA measures were performed for between-groups and within-group analyses. The mean of the initial CMSDQ total scores in both groups increased significantly in the 18th month (p < 0.001). However, the interaction effect of group and time (between and within factors) was not significant (p = 0.992). Work-related MSC is a common occupational health problem among nurses. This study showed that individual-level interventions are not likely to succeed in eliminating manual patient lifting by nurses. Our results suggested that interventions without administrative measures might have limited success

Work- and stress-related musculoskeletal and sleep disorders among health professionals: a cross-sectional study in a hospital setting in Switzerland

Background

Musculoskeletal and sleep disorders have been reported to be very common among health care and hospital workers and particularly nurses. They are assumed or found to be a result of psychological stress and/or physical strain or pain. However, no other study so far – at least in a hospital setting and for Switzerland – has considered and investigated musculoskeletal as well as sleep disorders in consequence of or rather in association with both physical workload and psychological stress.

Methods

Cross-sectional survey data of 1232 health professionals were used and analysed. Data were collected in 2015/16 among the health care workforces of three public hospitals and two rehabilitation clinics in the German-speaking part of Switzerland. Musculoskeletal and sleep disorders were assessed by three items taken from the Swiss Health Survey, a 2-item measure of accumulated low back, back, neck and shoulder pain and a single-item measure of problems in getting to sleep or sleeping through. Stratified and adjusted bivariate logistic and multivariate linear regression analyses were performed to calculate measures of association (adjusted odds ratios, z-standardized beta coefficients), to control for potential confounders, and to compare different health professions (nurses, physicians, therapists, other).

Results

Almost every fourth of the studied health professionals reported severe or even very severe musculoskeletal disorders (MSDs) and nearly every seventh severe sleep disorders (SDs). These prevalence rates were significantly or at least slightly higher among nurses than among physicians and other health care workers. General stress, work stress, physical effort at work, and particularly a painful or tiring posture at work were found to be clear and strong risk factors for MSDs, whereas only general and work-related stress were found to be significantly associated with SDs. There was no or only weak association between MSDs and SDs.

Conclusions

This study found MSDs to be largely a result of physical workload or rather poor posture at work and only secondarily a consequence of (general) stress, whereas SDs were revealed to be primarily a consequence of stress on and particularly off the job. Preventive strategies therefore have to differentiate and combine measures for the reduction of both psychological stress and physical strain.

Development and testing of a new electronic foot health promotion programme on nurses' foot self-care

Background

Nurses form the largest professional group in health care, and they spend most of their working day on their feet. From the perspective of work well-being, healthy feet are important to tolerate the physical demands of nursing work. However, little is known about how nurses’ foot self-care practices can be promoted with computerised interventions. The aim of this study was two-fold: to explore the preliminary effects of the electronic Foot Health Promotion Programme (FHPP) on foot self-care in nurses and to examine the usability of the programme.

Methods

A single group pretest-posttest design was used. The FHPP was targeted at nurses working in the operating theatre. The FHPP lasted for 4 weeks and focused on improving nurses’ knowledge and awareness of foot self-care through self-directed learning tasks. The primary outcome was knowledge of foot self-care. The secondary outcomes were foot health and work ability. Thirty-seven participants completed the study. The outcomes were assessed at baseline (April–June 2017) and 4 weeks (August–September 2017) after the intervention ended. The data were analysed statistically.

Results

Participants’ knowledge of foot self-care and foot health improved; however, the changes were not statistically significant. The FHPP was considered to be usable and has potential as a tool to increase knowledge of foot self-care among nurses.

Conclusions

The FHPP developed in this study is a newly developed potential tool to increase nurses’ knowledge of foot self-care. Application of the FHPP as part of occupational health care may enhance nursing personnel’s foot self-care and lower extremity health.

Translation, adaptation and validation of the Nurse-Work Instability Scale to Brazilian Portuguese

OBJECTIVE

to translate, adapt and test the psychometric properties of the Brazilian Nurse-Work Instability Scale.

METHOD

this was a methodological study following the translation steps: synthesis, back-translation, specialist´s committee, semantics analysis, pretest, and psychometric tests. The committee was composed of 5 specialists. For the semantics analysis, 18 nursing workers evaluated the instrument and 30 pretested it. For the psychometric tests, the sample size was 214 nursing workers. The internal construct validity was analyzed by the Rasch model. Reliability was assessed using internal consistency, and concurrent validity with Pearson's correlation between the Nurse-Work Instability Scale, and the Work Ability Index, Job Stress Scale.

RESULTS

a Nurse-Work Instability Scale in Brazilian Portuguese with 20 items showed an adequate reliability (0.831), stability (p <0.0001), and an expected correlation with Work Ability Index (r = -0.526; P<0.0001) and Job Stress Scale (r = 0.352; p <0.0001).

CONCLUSION

the instrument is appropriated to detect work instability in Brazilian nursing workers with musculoskeletal disorders. Its application is fundamental to avoid long-term withdrawal from work by early identification of the work instability. Furthermore, the scale can assist the development of actions and strategies to prevent the abandonment of the profession of nursing workers affected by musculoskeletal disorders.

Does work-induced fatigue accumulate across three compressed 12 hour shifts in hospital nurses and aides?

Fatigue-related impairments in the nursing workforce contribute to a multitude of health, safety, and economic consequences at the individual, organizational and societal levels. Long and compressed work schedules are commonly worked in the healthcare industry, but more research is needed to understand the cumulative effects of multiple work shifts on physiology-based performance outcomes in nurses. The purpose of this study was to compare the effects of a single nursing work shift versus three compressed (one every 24 hours) 12 hour shifts on performance-based fatigue in nurses and aides. Twenty-six fulltime hospital working nurses and aides (age = 36.1 ± 13.3 years) reported to the lab for testing before, immediately after working a single 12 hour shift, and after working three 12 hour shifts in a 72 hour period. Outcome measures included vigilance-based reaction time, lapses of attention, and muscle function assessments (lower and upper body muscle strength, explosive strength and vertical jump performance). All variables except hand grip strength showed a significant decline following the three work shifts. The psychomotor vigilance reaction time and lapses of attention variables also generally showed a significant decline from the end of shift one to the end of shift three, indicting an accumulation of fatigue in these metrics with increasing number of shifts worked. Muscle function variables responded early in the duty cycle, showing a significant decline after a single work shift, but did no further decline by the end of the third shift. These findings use objective measures to substantiate that fatigue impairments occur from working a single 12 hour shift, and in several instances, increase further with more successive work shifts. Caution should be employed by personnel and administrators with work schedules involving multiple compressed 12 hour shifts. Fatigue management strategies may be used to improve risks and consequences from fatigue-related mishaps, and this study reports several variables that appear sensitive to identifying and tracking fatigue in this population.

Nurse-work instability and incidence of sick leave - results of a prospective study of nurses aged over 40

BACKGROUND

The Nurse Work Instability Scale (Nurse-WIS) is an occupation-specific instrument that ascertains "work instability," the interval before restricted work ability or prolonged sick leave occurs. The objective of the study was to assess if nurses with a high risk baseline-score in the Nurse-WIS take longer periods of sick leave due to musculoskeletal diseases and/or psychological impairments than other nurses.

METHODS

A total of 4500 nurses randomly selected from one of the largest health insurance funds in Germany (DAK-Gesundheit) were invited by letter to participate in the study. The participants answered a questionnaire at baseline and gave consent to a transfer of data concerning sick leave during the twelve months following completion of the questionnaire from the health insurance to the study centre. Sensitivity, specificity and positive and negative predictive values (PPV and NPV) for long-term sick leave were calculated. In order to analyze the association between the Nurse-WIS and sick leave during follow-up, a multiple ordinal logistic model (proportional odds model) was applied.

RESULTS

A total of 1592 nurses took part in the study (response 35.6%). No loss of follow-up occurred. The number of nurses with a high score (20-28 points) in the Nurse-WIS was 628 (39.4%), and 639 (40.1%) had taken sick leave due to musculoskeletal diseases or psychological impairment during the follow-up period. The odds ratio for sick leave in nurses with a high Nurse-WIS score was 3.42 (95%CI 2.54-4.60). Sensitivity for long-term sick leave (< 42 days) was 64.1%, specificity 63.4%, PPV 17.0% and NPP 93.8%.

CONCLUSION

The German version of the Nurse-WIS predicts long-term sick leave, but the PPV is rather low. Combining questionnaire data with secondary data from a health insurer was feasible. Therefore further studies employing this combination of data are advisable.

Exoskeleton robot control for synchronous walking assistance in repetitive manual handling works based on dual unscented Kalman filter

Prolong walking is a notable risk factor for work-related lower-limb disorders (WRLLD) in industries such as agriculture, construction, service profession, healthcare and retail works. It is one of the common causes of lower limb fatigue or muscular exhaustion leading to poor balance and fall. Exoskeleton technology is seen as a modern strategy to assist worker’s in these professions to minimize or eliminate the risk of WRLLDs. Exoskeleton has potentials to benefit workers in prolong walking (amongst others) by augmenting their strength, increasing their endurance, and minimizing high muscular activation, resulting in overall work efficiency and productivity. Controlling exoskeleton to achieve this purpose for able-bodied personnel without impeding their natural movement is, however, challenging. In this study, we propose a control strategy that integrates a Dual Unscented Kalman Filter (DUKF) for trajectory generation/prediction of the spatio-temporal features of human walking (i.e. joint position, and velocity, and acceleration) and an impedance cum supervisory controller to enable the exoskeleton to follow this trajectory to synchronize with the human walking. Experiment is conducted with four subjects carrying a load and walking at their normal speed- a typical scenario in industries. EMG signals taken at two muscles: Right Vastus Intermedius (on the thigh) and Right Gastrocnemius (on the calf) indicated reduction in muscular activation during the experiment. The results also show the ability of the control system to predict spatio-temporal features of the pilots’ walking and to enable the exoskeleton to move in concert with the pilot.

Nurses' Perceptions of Their Foot Health: Implications for Occupational Health Care

Nursing practice includes static standing and much walking causing strains to lower extremities. However, little is known about nurses' foot health and particularly their perceptions of their foot health. Therefore, in this study operating room nurses' perceptions of their foot health was investigated and promoting and hindering factors were identified. In total, 14 operating room nurses participated in in-depth interviews. The informants regarded foot health as part of general health and moreover a significant part of work well-being. Promoting factors for foot health were activity in sports and foot self-care as well as varying work conditions and seeing patients with severe foot conditions which served as a motivating factor to care for their own feet. On the contrary, hindering factors were unsuitable footwear, constant standing, and lack of motivation to care for their own feet. Based on this study, nurses' value their foot health which should be promoted. Nurses could benefit from annual foot health assessments and foot self-care education provided by occupational health professionals.

Lower limb pain among workers: a cross-sectional analysis of the fifth European Working Conditions Survey

OBJECTIVE

Develop a model to predict the prevalence of lower limb pain using indicators of high workplace exposures based on the fifth European Working Conditions Survey, evaluate its impact and explore its significance for work-related health problems.

METHOD

Cross-sectional interview data of 35,372 workers from 27 countries of the European Union in 2010 (EU27) were used to develop (20% sample) and validate (80% sample) a logistic regression model for lower limb pain. Independent variables included descriptions of working conditions, assessments of physical and psychosocial exposures at work, and demographic factors. The impact of the model was explored through the amount of lower limb pain cases attributable to work and estimating work absences correlated with lower limb pain.

RESULTS

The resulting logistic model included ten risks indicators and one preventive factor. The highest odds ratios (OR) corresponded to "tiring or painful positions" OR 2.0, 99% confidence interval (99% CI) 1.9-2.2, and "not satisfied with level of working conditions in the job" (OR 1.6, 99% CI 1.5-1.7). The prevalence of work-related lower limb pain was 16.5% for men and 15.8% for women for the 27 countries of the European Union. Estimates based on the developed model revealed more than 34 million cases of work-related lower limb pain, where four physical risks explained about 22 million cases. In addition, more than 3 million days of absence from work in 2010 could be attributed to lower limb pain.

CONCLUSION

Lower limb pain is highly prevalent among the European workforce and work exposures are a major contributing factor. Effective workplace interventions should aim at improving working conditions at workplaces with multiple risks.
