Subgroup characteristics in care workers with low back pain: cluster analysis-based severity of central sensitivity syndromes and low back pain

PURPOSE

This multicentre, collaborative, cross-sectional study aimed to explore the characteristics of subgroups based on central sensitivity syndromes (CSSs) and low back pain (LBP) severity. Furthermore, we investigated the relationship between the classified subgroups and work status among the care workers.

PATIENTS AND METHODS

In 660 care workers, we assessed LBP intensity, pain duration, pain sites, CSS (using the central sensitization inventory-9), psychological factors (using the pain catastrophizing scale and pain self-efficacy questionnaire), and work status (interference, amount of assistance, frequency of assistance, and work environment). We used hierarchical clustering analysis to divide the participants into subgroups based on CSS and LBP severity. We further performed multiple comparison analyzes and adjusted the residuals (chi-square test) to reveal differences between clusters.

RESULTS

Care workers with LBP were divided into four subgroups (Cluster 1: no CSS and mild LBP, Cluster 2: mild CSS and severe LBP, Cluster 3: mild CSS and mild LBP, Cluster 4: severe CSS and moderate LBP). Cluster 4 tended to have a higher number of pain sites, severe pain catastrophizing, and poor pain self-efficacy. In addition, Cluster 4 showed a higher frequency of assistance and an inadequate working environment and equipment. By contrast, Cluster 2 tended to have low pain self-efficacy. In addition, Cluster 2 experienced the highest work-related interference compared with any of the subgroups.

CONCLUSION

Our findings suggested that the severe LBP and severe CSS subgroups had common and different characteristics concerning psychological factors and work status, including interference with work. Our results may help to improve the management of care workers with LBP.

Patient handling training interventions and musculoskeletal injuries in healthcare workers: Systematic review and meta-analysis

Workplace injuries are a serious issue for the health and social care industry, with the sector accounting for 20 % of all serious claims reported. The aim of this systematic review was to determine whether patient handling training interventions that included instruction on patient transfer techniques are effective in preventing musculoskeletal injuries in healthcare workers. Methods: Electronic databases MEDLINE (Ovid), EMBASE (Ovid), CINAHL (EBSCO) and Health and Safety Science Abstracts (ProQuest) were searched for controlled trials from January 1996-August 2022. Risk of bias was evaluated using the PEDro scale and overall certainty of evidence assessed using the Grading of Recommendations, Assessment, Development and Evaluation for each meta-analysis. Results: A total of nine studies (3903 participants) were included. There is moderate certainty evidence that could not conclude whether patient handling training affects the 12-month incidence of lower back pain (OR = 0.83, 95 % CI [0.59, 1.16]). There is low certainty evidence that patient handing training does not prevent lower back pain in health professionals without pre-existing pain (MD = -0.06, 95 % CI [-0.63, 0.52]) but may reduce lower back pain in those with pre-existing pain (MD = -2.92, 95 % CI [-5.44, -0.41]). The results also suggest that there may be a positive effect of training incorporating risk assessment on musculoskeletal injury rates; however the evidence is of very low certainty. There is low certainty evidence from a single study that training may have a short-term effect on sickness absences.) Conclusions: There is a lack of evidence to support patient handling training when delivered to all healthcare staff. Training in its current form may be an ineffective strategy for reducing musculoskeletal injuries and pain. High quality disinvestment studies or trials incorporating risk assessment strategies are warranted. Practical Applications: This review suggests health service managers question the effectiveness of current patient handling training practices and consider evaluating current practices before allocating resources to meet employee risk reduction obligations.

Nurses sustain manual handling risk assessment behaviours six-months after a training program to move patients safely: a pre-post study

PURPOSE

To determine if a patient manual handling training program focused on dynamic manual handling risk assessment for staff and patient safety, together with the patient's need for physical rehabilitation, can be transferred and sustained in clinical practice.

MATERIALS AND METHODS

Using a pre-post design, nurses (n = 72) from acute and rehabilitation wards participated in a 4-hour training session teaching dynamic manual handling risk assessment to safely move patients. Clinical observations audits of patient transfers were conducted prior to, and at 1-month and 6-months post training. Surveys determined experiences of training. Nurse musculoskeletal injuries and patient falls were measured 6-months after training.

RESULTS

Program patient handling skills were competently implemented 89% of the time 1-month following training and were sustained 6-months following training. There was no change in falls rates and staff injury rates were very low pre- and post-training. Training was well received and all nurses passed the competency assessment.

CONCLUSION

The patient handling training program taught nurses to better identify factors associated with risk to themselves and their patients and gave them improved skills to help patients move. Skills were incorporated safely into clinical practice and sustained at 6-months. It is uncertain whether training impacted musculoskeletal injuries.Implications for rehabilitationA dynamic manual handling risk assessment program for safely transferring and moving patients balances staff safety with the patient's need for physical rehabilitation.Nurses can be taught risk assessment skills to better identify factors associated with risk to themselves and their patients that can be translated to clinical practice.Thorough risk assessment at the point of the nurse-patient interaction can enable a patient to move at their highest level of function thus providing patients with opportunities to progress their rehabilitation at every interaction.

Interventions to prevent and reduce work-related musculoskeletal injuries and pain among healthcare professionals. A comprehensive systematic review of the literature

INTRODUCTION

Work-related musculoskeletal disorders (WMSDs) are among the main causes of injury and pain in healthcare professionals. Previous reviews provided a fragmented view of the interventions available for WMSDs. This review aims to provide a comprehensive description of interventions for preventing and reducing work-related musculoskeletal injuries and/or pain among healthcare professionals, and to assess the methodological quality of studies.

METHODS

A systematic literature review was performed, based on the Effective Public Health Practice Project process. A comprehensive search was conducted on six peer-reviewed databases and manually. The methodological quality of the studies included was rated as weak, moderate, or strong. The studies were organized based on the 2019 classification of the interventions by Oakman and colleagues.

RESULTS

Twenty-seven articles were included reporting individual (n = 4), task-specific (n = 4), work organization and job design (n = 2), work environment (n = 1), and multifactorial (n = 16) interventions. Overall quality rating was strong for 6 studies, moderate for 16, and weak for 5. Individual interventions such as neuromuscular and physical exercise were effective in reducing pain. Task-specific and work organization interventions could prevent certain injuries. Significant reduction of both injuries and pain resulted from multifactorial interventions, which were reported by the majority of strong (n = 5) and moderate (n = 10) quality articles.

CONCLUSIONS

This review provides healthcare professionals with evidence-based information to plan interventions targeted towards reducing WMSDs. In particular, more efforts are needed to implement and extend effective multifactorial interventions. Moreover, studies about each professional healthcare target group are needed.

PRACTICAL APPLICATION

Our results can guide policy-makers, healthcare managers and professionals to choose the best strategies to prevent and reduce WMSDs and to shape continuous education programs. This study prompts clinicians to develop inter-professional collaborations and to practice physical activities in order to reduce WMSDs.

Associations of Central Sensitization-Related Symptoms with Low Back Pain-Related Factors and Work Status in Caregivers

Low back pain (LBP) is associated with psychological factors and central sensitization-related symptoms (CSSs). The relationship between CSSs, LBP-related factors, and work status in caregivers remain unclear. This multicentre, collaborative, cross-sectional study aimed to determine the association between CSS severity, LBP-related factors, and work status in caregivers with LBP. We measured LBP intensity, pain duration, pain sites, CSSs (using the Central Sensitization Inventory-9: CSI-9), psychological factors (using the Pain Catastrophizing and Pain Self-Efficacy scales), and work status (interference, amount of assistance, frequency of assistance, and work environment) in 660 caregivers. CSS severity was categorised as no (CSI-9:0−9), mild (CSI-9:10−19), or moderate/severe (CSI-9:20−36). We further performed multiple comparison analyses and adjusted the residual chi-square to reveal differences between CSS severity groups. Caregivers with more severe CSSs tended to exhibit worse LBP intensity (p < 0.01), widespread pain (p < 0.01), catastrophic thinking (p < 0.01), and pain self-efficacy (p < 0.01), and they also tended to experience work interference (p < 0.01). Caregivers without CSSs tended to receive a smaller amount of assistance with a lower frequency (p < 0.05). The number of participants with an adequate environment and equipment was significantly less in the moderate/severe CSS group (p < 0.01). Thus, our findings may suggest that CSS severity is associated with LBP intensity, widespread pain, psychological factors, and work status in caregivers.

Translation and cross-cultural adaptation of the risk assessment instrument TilThermometer for a Swedish version – patient handling in the healthcare sector

Background

Work-related musculoskeletal disorders are common in the healthcare sector due to exposure of physical demanding work tasks. Risk assessment is necessary to prevent injuries and promote a safety culture. The TilThermometer has proved to be useful in the Netherlands for assessing healthcare workers’ physical exposure to patient handling. The aim of this study was to translate the risk assessment instrument TilThermometer from Dutch to Swedish, perform cross-cultural adaptation, and evaluate its linguistic validity to a Swedish healthcare context.

Methods

Translation and validation process was performed according to following eight steps: 1) Translation (two translators), 2) Synthesis, 3) Back-translation (two back-translators), 4) Synthesis, 5) Linguistic review (one bilingual reviewer), 6) fifteen experts in a panel review according to Delphi-method, 7) Semi-structured interviewing eleven informants, analyzed using qualitative content analysis and step 8) discussion and input from creators of the instrument.

Results

A new Swedish version, the TilThermometer, was provided through the translation process (steps 1–5). The linguistic validity and usefulness were confirmed thru step 6 and 7. Consensus was reached in the expert review after two rounds, comments were analyzed and grouped into five groups. The qualitative content analyses of the interviews emerged in to three categories: 1) “User-friendly and understandable instrument”, 2) “Further development”, and 3) “Important part of the systematic work-environment management”.

Conclusion

In this study, the cross-cultural adaption and translation performed of the Swedish version of TilThermometer assured linguistic validity. This is this first phase before further testing the psychometrics aspects, inter-rater reliability and feasibility of TilThermometer. In the second phase TilThermometer will be implemented and evaluated together with other measures in the Swedish healthcare sector.

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

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

Improving physical mobility is critical for wellbeing in people with severe impairment after an acquired brain injury: a qualitative study

OBJECTIVES

1) Understand the experience, and personal significance, of mobility skills for people with severe mobility impairment after brain injury 2) Determine how these evolve over time.

DESIGN

Longitudinal qualitative study.

PARTICIPANTS

Ten adults, unable to walk at 8 weeks post-injury.

METHODS

Participants were interviewed up to three times, at three-month intervals. Semi-structured interviews were transcribed and coded independently by two researchers, then themes developed. Codes were then reviewed longitudinally.

RESULTS

Initial analysis derived six themes: I lost everything overnight; It feels frustrating; Walking is absolutely the most important; I need help; I'm making progress; I can start doing things that I used to be able to do. Participants described overwhelming losses, with loss of mobility affecting many aspects of life. All participants described progress other than walking that was critical for their wellbeing, including assisted standing and transfers without a lifter. Themes from longitudinal analyses: My losses softened by progress; Walking means freedom; Control helps adjustment happen; Challenges keep coming. Over time, participants valued greater control within their lives and progress with mobility was key.

CONCLUSION

Participants saw mobility as crucial to recovering control of life. Mobility achievements other than independent walking matter to individuals after brain injury.

What Do We Know About Interventions to Prevent Low Back Injury and Pain Among Nurses and Nursing Students? A Scoping Review

STUDY BACKGROUND

Back injuries are common among nurses worldwide with lifetime prevalence of lower back pain ranging from 35% to 80%, making nursing a profession at great risk for back injuries.

PURPOSE

This systematic scoping review explored and mapped existing evidence regarding the prevention of low back injury and pain among nurses and nursing students.

METHODS

Using a scoping review methodology, six databases were searched initially in September 2017 and updated June 2020. Studies investigating interventions designed to reduce back injuries and pain among regulated nurses and student nurses, published in peer-review journals and written in English, were eligible for inclusion in this review. Quantitative, qualitative, and mixed methods studies of regulated nurses, nursing students, and nursing aides were included. Two independent reviewers screened, critically analysed studies using a quality appraisal tool, extracted data, and performed quality appraisals.

RESULTS

Two searches yielded 3,079 abstracts and after title, abstract and screening, our final synthesis was based on 48 research studies.

CONCLUSIONS

Forty years of research has demonstrated improvements in quality over time, the efficacy of interventions to prevent back injury and pain remains unclear, given the lack of high-quality studies. Further research, using multi-dimensional approaches and rigorous study designs, are needed.

A systematic review of work interventions to promote safe patient handling and movement in the healthcare sector

PURPUSE

The aim of this systematic review was to describe interventions which promote safe patient handling and movement (PHM) among workers in healthcare by reviewing the literature of their effectiveness for work and health-related outcomes.

METHODS

Data bases were searched for studies published 1997‒2018. Measures was operationalised broadly, capturing outcomes of work and health. Only Randomized controlled trials (RCTs) and cohort studies with control group were included. Quality was assessed using evidence-based checklists by Swedish Agency for Health Technology Assessment and Assessment of Social Services.

RESULTS

The systematic review included 10 RCTs and 19 cohort. Providing work equipment and training workers is effective: it can increase usage. Training workers to be peer coaches is associated with fewer injuries. Other effective strategies are participatory ergonomics and management engagement in collaboration with workers, facilitating safe PHM.

CONCLUSIONS

This systematic review suggests interventions for safe PHM with an impact of health-related outcomes should include access to work equipment, training as well as employer and employee engagement. The additional impact of multifaceted interventions is inconclusive.

PRACTITIONER SUMMARY

In clinical practice, there is a need for employers in healthcare to; 1) provide healthcare workers access to suitable work equipment. 2) provide training on how to use work equipment to prevent work-related injuries. Furthermore, the study also indicates that 3) training and appointing peer coaches can facilitate safe manual handling and movement (PHM) and, 4) It can be beneficial to involve workers in a participatory approach.

The prevalence of upper quadrants work-related musculoskeletal disorders and their predictors among registered nurses

BACKGROUND

Work-related musculoskeletal disorders (WMSDs) represent a significant health challenge facing nurses. However, very few studies investigated the prevalence of WMSDs among nurses and their predictors comprehensively using a valid and reliable set of standardized outcome measures.

OBJECTIVE

This study aimed to investigate the prevalence WMSDs of upper quadrants and their predictors among registered nurses in Jordanian hospitals.

METHODS

A cross-sectional study recruited 597 registered nurses from different hospitals in Jordan. A self-administered survey distributed in targeted hospitals wards. Outcome measures included Nordic Musculoskeletal Questionnaire (NMQ), Depression Anxiety Stress Scale (DASS), Pittsburgh Sleep Quality Index (PSQI), International Physical Activity Questionnaire (IPAQ), sociodemographic data, and manual handling and work habits. Prevalence of musculoskeletal complaints was reported using descriptive analysis. Logistic regression analyses were used to identify predictors of WMSDs at each upper quadrant body site.

RESULTS

Twelve-month WMSDs prevalence was the highest at the neck (61.1%), followed by the upper back (47.2%), shoulders (46.7%), wrist and hands (27.3%), and finally at the elbow (13.9%). Being a female, poor sleep quality, high physical activity level, poor ergonomics, increased workload, and mental stress were significant predictors of increased upper quadrant WMSDs among nurses.

CONCLUSIONS

Upper quadrant WMSDs among nurses in Jordan are highly prevalent. Identified significant predictors of these WMSDs should be given full consideration by clinicians and health policymakers. Future studies are needed to reveal the progressive nature of upper quadrant WMSDs and strategies to modify their risk factors.

Predictors and prevalence of lower quadrant work-related musculoskeletal disorders among hospital-based nurses: A cross-sectional study

BACKGROUND

Work-related musculoskeletal disorders (WMSDs) represent a significant problem for nurses. It is thus important to investigate nurses' WMSDs prevalence and comprehensive predictors including motor, mental, and lifestyle factors.

OBJECTIVES

To investigate the prevalence and predictors of lower quadrant WMSDs among Jordanian nurses.

METHODS

A cross-sectional design, using self-administered questionnaires, was utilized. Outcome measures included Nordic Musculoskeletal Questionnaire (NMQ), Depression Anxiety Stress Scale (DASS21), Pittsburgh Sleep Quality Index (PSQI), sociodemographic data, and self-reported work ergonomics. Descriptive analyses were used to determine lower quadrant WMSDs prevalence and regression analyses were used to assess their predictors.

RESULTS

A total of 597 nurses participated in the study. Twelve-month prevalence of lower quadrant WMSDs were 77.4% in lower back, 22.3% in hips, 37.5% in knees, and 28.5% in ankles and feet. Older age, longer years of experience, high workload, poor work habits and ergonomics, high physical activity level, availability of patient handling equipment, handling policies, stress, and anxiety were significant predictors (p< 0.05) of lower quadrant WMSDs.

CONCLUSIONS

Jordanian nurses have a high prevalence of lower quadrant WMSDs. Many modifiable risk factors of WMSDs were identified. Future studies need to design effective treatment and preventive strategies for nurses' WMSDs to improve their work efficiency and wellbeing.

Ergonomic Stressors Among Pregnant Healthcare Workers: Impact on pregnancy outcomes and recommended safety practices

Workplace environment can have a considerable impact on the physical, psychological and maternal health of pregnant healthcare workers. This article aimed to summarise the impact of work-related ergonomic stressors on pregnancy outcomes for healthcare workers, along with potential interventions to resolve these stressors. A narrative review analysis using the Pearl Growing Strategy was conducted between February 2019 and June 2020 to identify English-language articles published between 2000 and 2020. A total of 89 studies were identified from the SCOPUS (Elsevier, Amsterdam, Netherlands), MEDLINE® (National Library of Medicine, Bethesda, Maryland, USA) databases and Google Scholar (Google LLC, Menlo Park, California, USA). The results indicated that poor work-related ergonomics had detrimental effects on pregnancy outcomes, resulting in spontaneous abortions, preterm delivery, low birth weight babies and infertility. Policymakers and employers should conduct ergonomic assessments and implement appropriate practices to ensure the safety of pregnant healthcare workers.

Evaluation of Absenteeism, Pain, and Disability in Nurses With Persistent Low Back Pain Following Cognitive Functional Therapy: A Case Series Pilot Study With 3-Year Follow-Up

OBJECTIVE

Persistent low back pain (PLBP) is a common and costly health problem worldwide. Better strategies to manage it are required. The purpose of this study was to longitudinally evaluate absenteeism, pain, and disability in nurses with PLBP following a cognitive functional therapy (CFT) intervention.

METHODS

In this case series pilot study, 33 eligible nurses with PLBP were recruited. During the baseline phase (phase A; no intervention), outcome measures were collected on 2 occasions 6 months apart (A1 and A2). During phase B, participants received an individualized CFT intervention for 14 weeks. During phase C (no intervention), outcomes were measured immediately after the intervention, as well as 3, 6, 9, 12, and 36 months after the intervention (secondary outcomes only until 12 months). LBP-related work absenteeism, pain intensity (numerical pain rating scale) and disability (Oswestry Disability Index) were the primary outcomes. Health care seeking, a range of psychological and lifestyle variables, and global perceived effect were secondary outcomes.

RESULTS

Days of absenteeism due to LBP were significantly reduced in the first and second calendar years after the CFT intervention but not the third and fourth. Disability was significantly reduced immediately after (-4.4; 95% CI = -6.5 to -2.2) and at 3 months (-4.3; 95% CI = -6.6 to -2.0), 9 months (-6.0; 95% CI = -8.1 to -3.9), and 12 months (-4.9; 95% CI = -7.0 to -2.8) after the intervention. Pain was significantly reduced immediately after (-1.2; 95% CI = -1.7 to -0.8) and at 3 months (-1.5; 95% CI = -2.0 to -0.9), 9 months (-1.1; 95% CI = -1.9 to -0.3), and 12 months (-0.9; 95% CI = -1.5 to -0.2) after the intervention. Total health care seeking (consults and proportion of participants) was significantly reduced after the intervention. All psychosocial variables, except for 1, demonstrated significant improvements at all follow-up assessments.

CONCLUSIONS

This case series pilot study demonstrated significant reductions in LBP-related absenteeism, pain intensity, disability, health care seeking, and several psychological and lifestyle behaviors until the 1-year follow-up among nurses with PLBP following an individualized CFT intervention. Further evaluation of the efficacy of CFT in high-quality randomized clinical trials among nurses is recommended.

Injury rates before and after the implementation of a safe resident handling program in the long-term care sector

Manual resident handling (RH) tasks increase risk of musculoskeletal disorders (MSDs) for clinical staff in nursing homes. To reduce the incidence and cost of MSDs, a large healthcare corporation instituted a Safe Resident Handling Program (SRHP) comprising purchase of mechanical lifting equipment, worker training, and detailed usage/maintenance protocols. The program was initially administered by a third-party company; after three years, program responsibility shifted to individual centers. Workers' compensation claim rates were compared before and after SRHP implementation. Claims and FTEs were classified as "pre-SRHP," "first post period" (up to 3 years post-SRHP), or "second post period" (4-6 years post-SRHP), based on claim date relative to implementation date for each center. Complete data were available for 136 nursing homes with average annual employment of 18,571 full-time equivalents. Over the 8-year period, 22,445 claims were recorded. At each time period, the majority of RH claims affected the back (36% low, 15% other) and upper extremity (26%). Workers' compensation claims were reduced by 11% during the first post period and 14% during the second post period. RH-related claims were reduced by 32% and 38%, respectively. After six years, the rate for all claims had decreased in 72% of centers, and RH claim rates decreased in 82%. Relative risk for post-/pre-SRHP injury rates increased for centers with less developed wellness programs, unionized centers, and centers with higher LPN turnover pre-SRHP. Injury reduction among these nursing home workers is plausibly attributable to the introduction of mechanical lifting equipment within the context of this multi-faceted SRHP.

Occupational injuries of teachers and educational staff at special schools with multiple and severely handicapped children in Rhineland-Palatinate (Germany): results of a cross-sectional study

OBJECTIVES

The present study aimed to describe the prevalence, type, and influencing factors of occupational injuries of staff working at special schools with multiple and severely handicapped pupils in Southwestern Germany.

METHODS

This cross-sectional study was carried out between August 2010 and August 2012 at 13 special schools with focus on motoric and/or holistic development of handicapped pupils in Rhineland-Palatinate (Germany). Participants were interviewed using a written questionnaire.

RESULTS

There were 395 participants (response proportion: 59.7%) in our study, with 390 being eligible for statistical analysis. Respondents were on average 45 years old and mainly female (86.9%). The 12-month injury prevalence was 16.9%. Joint dislocations, sprains, and torn ligaments (41.6%) were the main types of injuries. Pupils (59.8%) and auxiliary equipment (12.2%) were identified as the main causes of injury by the respondents. Multivariable logistic regression analysis showed that washing pupils (using auxiliary equipment) (aOR, 3.93; 95% CI, 1.66-9.31) and daily physical strain due to unexpected conduct of pupils (aOR, 3.70; 95% CI, 1.20-11.37) were the main influencing factors for an occupational injury.

CONCLUSIONS

Almost one in five persons suffered an occupational injury in the previous 12 months. Nursing activities, including close contact with pupils, were identified as the most important factors for an injury. In order to prevent injuries at special schools, a multifaceted approach is necessary. This includes sufficient supply of auxiliary devices including proper technical maintenance. Furthermore, regular participation in training for manual handling of heavy loads and schooling on the technical use of auxiliary devices should be encouraged.

On physiological demands and sustainability in meat cutting

Meat cutters' work has been investigated by several researchers. However, knowledge about the physiological demands of meat cutting is almost lacking. The aim of this explorative study was to assess physiological demands in meat cutting, to compare them with International Labour Organization (ILO) recommendations for acceptable workload and to discuss the findings in relation to individual and work-related factors. In accordance with the ILO recommendations, work was categorised as sustainable or non-sustainable based on critical relative aerobic strain (RAS) levels. Twenty-one beef and pork cutters participated in the study, which included workload measurements, assessment of workplace and individual factors. Thirteen meat cutters were categorised as having non-sustainable and eight as having sustainable work. Results suggest that the workload is higher in beef cutting than in pork cutting, and that longer work experience is related to lower RAS. Other factors contributing to the physical workload are discussed.

PRACTITIONER SUMMARY

Meat-cutting work may exceed recommended physical workload levels. Beef cutting is physically more demanding than pork cutting. Furthermore, factors such as years in the profession, knife sharpness, work pace, wage system, working technique, maximum oxygen uptake level and muscular strength should be considered when planning actions regarding the workload for meat cutters.

Developing a comprehensive approach to risk management of musculoskeletal disorders in non-nursing health care sector employees

This study of selected jobs in the health care sector explored a range of physical and psychosocial factors to identify those that most strongly predicted work-related musculoskeletal disorders (WMSD) risk. A self-report survey was used to collect data on physical and psychosocial risk factors from employees in three health care organisations in Victoria, Australia. Multivariate analyses demonstrated the importance of both psychosocial and physical hazards in predicting WMSD risk and provides evidence for risk management of WMSDs to incorporate a more comprehensive and integrated approach. Use of a risk management toolkit is recommended to address WMSD risk in the workplace.

The Use of the Self-Standing Turning Transfer Device to Perform Bed-To-Chair Transfers Reduces Physical Stress among Caregivers of Older Patients in a Middle-Income Developing Country

Manual transfer of elderly patients remains commonplace in many developing countries because the use of lifting equipment, such as hoists, is often considered unaffordable luxuries. The aim of this study was, therefore, to evaluate the usage and potential benefits of a low-cost, mechanical turning transfer device among elderly patients and their caregivers on a geriatric ward in a developing country in South East Asia. Fifty-six inpatients, aged 66–92 years, on a geriatric ward, and their caregivers were recruited. Participants were asked to transfer from bed-to-chair transfer with manual assistance, and the task was repeated using the Self-standing Turning Transfer Device (STurDi). The time taken to perform manual transfers and STurDi-assisted transfers was recorded. Physical strain was assessed using the perceived physical stress-rating tool for caregivers with and without the use of the device. User satisfaction was evaluated using the usefulness, satisfaction, and ease of use questionnaire. There was a significant reduction in transfer-time with manual transfers compared to STurDi-assisted transfers [mean (SD) = 48.39 (13.98) vs. 36.23 (10.96); p ≤ 0.001]. The physical stress rating was significantly lower in STurDi-aided transfers compared to manual transfers, shoulder [median (interquartile range) = 0 (1) vs. 4 (3); p = 0.001], upper back [0 (0) vs. 5 (4); p = 0.001], lower back [0 (1) vs. 5 (3), p = 0.001], whole body [1 (2) vs. 4 (3), p = 0.001], and knee [0 (1) vs. 1 (4), p = 0.001]. In addition, majority of patients and caregivers definitely or strongly agreed that the device was useful, saved time, and was easy to use. We have therefore demonstrated in a setting where manual handling was commonly performed that a low-cost mechanical transfer device reduced caregiver strain and was well received by older patients and caregivers.

Interventions to reduce injuries when transferring patients: a critical appraisal of reviews and a realist synthesis

OBJECTIVES

There has been extensive investment in programmes to reduce injuries among health care staff caused by moving and handling patients or residents. Given conflicting evidence regarding the effectiveness of such programmes, the present paper conducted a critical appraisal of systematic reviews assessing the effectiveness of interventions in reducing back pain and injuries among healthcare staff. A realist synthesis was conducted on a second set of reports to identify best practices for moving and handling programmes.

DESIGN

A critical appraisal of systematic reviews and a realist synthesis to identify best practices for moving and handling programmes.

DATA SOURCES

A literature search of five databases (Medline, EMBASE, CINAHL, PsycINFO and ScienceDirect) located 150 reports assessing programme outcomes published in refereed journals between 2000 and 2013.

REVIEW METHODS

The critical appraisal included six systematic reviews. The realist synthesis included 47 studies that provided descriptive information about programme mechanisms.

RESULTS

Five of the six systematic reviews covered interventions involving either staff training or training and equipment supply. One review covered multi-component interventions. All concluded that training staff by itself was ineffective. There were differing conclusions regarding the effectiveness of training and equipment interventions and multi-component programmes. The reviews provided little information about the content of programme components. The realist synthesis noted the need for management commitment and support, and six core programme components; a policy requiring safe transfer practices, ergonomic assessment of spaces where people are transferred, transfer equipment including lifts, specific risk assessment protocols, adequate training of all care staff, and coordinators coaches or resource staff. These programme components are likely to be synergistic; omitting one component weakens the impact of the other components.

CONCLUSIONS

Five systematic reviews provided little information regarding the core components of effective programmes. Given the absence of experimental trials for multi-component programmes, the best available evidence for the effectiveness of multi-component programmes is from pre-post studies and large-scale surveys. The realist synthesis provided detailed information about the core components for effective programmes. Further studies, which include qualitative data, are needed to provide evidence about the specific mechanisms through which components contribute to effective patient handling programmes.

Improving meat cutters' work: changes and effects following an intervention

Meat cutters face higher risks of injury and musculoskeletal problems than most other occupational groups. The aims of this paper were to describe ergonomics changes implemented in three meat cutting plants and to evaluate effects related to ergonomics on the individual meat cutters and their work. Data was collected by interviews, observations, document studies and a questionnaire (n = 247), as a post intervention study. The changes implemented consisted of reducing knife work to a maximum of 6 h per day and introducing a job rotation scheme with work periods of equal length. Tasks other than traditional meat cutting were added. A competence development plan for each meat cutter and easy adjustment of workplace height were introduced. The questionnaire showed a reduction in perceived physical work load. In general, the changes were perceived positively. Figures from the company showed a positive trend for injuries and sick leave.

Changes in ergonomic exposures of nursing assistants after the introduction of a safe resident handling program in nursing homes

We evaluated the effect of a nursing home safe resident handling intervention on the ergonomic exposures of nursing assistants. The healthcare version of the Postures, Activities, Tools and Handling (PATH) method was used by 12 observers to examine postures, manual handling, and resident handling pre-intervention and at three months, 12 months, 24 months, and 36 months post-intervention. There were marked downward trends in proportion of work time spent repositioning and transferring residents, and an increased use of handling equipment in transferring (Cochran-Armitage tests: all p-values <0.001). While resident handling, nursing assistants were also more likely post-intervention to be in neutral trunk postures, walking rather than standing still, working with both arms below 60°, and less likely to lift loads greater than 22.7 kg. Lateral transfer devices were infrequently observed in use for repositioning; additional training on the use of this equipment is recommended to increase the benefits from the intervention program.

RELEVANCE TO INDUSTRY

The study describes reductions in postural and manual handling loads of nursing assistants in nursing homes resulting from increased use of resident handling equipment following equipment installation with training and administrative support.

It’s not about the hoist: A narrative literature review of manual handling in healthcare

The manual handling of people and objects is integral to the provision of nursing care to patients globally. Despite over 30 years of research intended to guide improvements for nurses’ safety, substantial rates of manual handling injuries persist internationally within the nursing profession. This paper reviews the contemporary international literature regarding manual handling interventions noting the unique context for injury prevention strategies within healthcare. The review includes the recognition of underlying assumptions inherent in the conceptualisation of manual handling and its management, and the preponderance of the post-positivist paradigm in this field.

The complexity of manual handling in healthcare has resulted in a theoretical shift from single factor interventions based on technique training towards an emerging multidimensional approach. However the key elements for sustainable solutions to reduce nurses’ manual handling injuries have not yet been identified and consensus is lacking regarding the implementation and appropriate evaluation of injury prevention programmes. Furthermore, whilst the literature is replete with data derived from surveys or insurance industry records of compensation claims, there is a dearth of literature exploring nurses’ manual handling experiences. The in-depth investigation of nurses’ perspectives on manual handling may uncover new knowledge critical to improvement of the manual handling issues.

Work-related activities associated with injury in occupational and physical therapists

OBJECTIVE

The purpose of this study was to examine work activities associated with work-related injury (WRI) in occupational and physical therapy.

PARTICIPANTS

1,158 occupational and physical therapists in Wisconsin responded to a mailed survey, from a total of 3,297 OTs and PTs randomly selected from the State licensure list.

METHODS

The study used a cross-sectional, survey design. Participants reported information about WRI they sustained between 2004 and 2006, including the activities they were performing when injured. Investigators analyzed 248 injury incidents using qualitative and quantitative analysis.

RESULTS

Data were examined across OT and PT practice in general, and also by practice area. Manual therapy and transfers/lifts were associated with 54% of all injuries. Other activities associated with injury were distinct to practice area, for example: floor work in pediatrics; functional activities in acute care; patient falls in skilled nursing facilities; and motor vehicle activities in home care.

CONCLUSIONS

Injury prevention activities must address transfers and manual therapy, but also must examine setting-specific activities influenced by environment and patient population.

A biomechanical assessment of floor and overhead lifts using one or two caregivers for patient transfers

This study investigated the differences in peak external hand forces and external moments generated at the L5/S1 joint of the low back due to maneuvering loaded floor-based and overhead-mounted patient lifting devices using one and two caregivers. Hand forces and external moments at the L5/S1 joint were estimated from ground reaction forces and motion capture data. Caregivers gave ratings of perceived exertion as well as their opinions regarding overhead vs. floor lifts. Use of overhead lifts resulted in significantly lower back loads than floor lifts. Two caregivers working together with a floor lift did not reduce loads on the primary caregiver compared to the single-caregiver case. In contrast, two-caregiver operation of an overhead lift did result in reduced loads compared to the single-caregiver case. Therefore, overhead lifts should be used whenever possible to reduce the risk of back injury to caregivers. The use of two caregivers does not compensate for the poorer performance of floor lifts.

Differences among nursing homes in outcomes of a safe resident handling program

A large nursing home corporation implemented a safe resident handling program (SRHP) in 2004-2007. We evaluated its efficacy over a 2-year period by examining differences among 5 centers in program outcomes and potential predictors of those differences. We observed nursing assistants (NAs), recording activities and body postures at 60-second intervals on personal digital assistants at baseline and at 3-month, 12-month, and 24-month follow-ups. The two outcomes computed were change in equipment use during resident handling and change in a physical workload index that estimated spinal loading due to body postures and handled loads. Potential explanatory factors were extracted from post-observation interviews, investigator surveys of the workforce, from administrative data, and employee satisfaction surveys. The facility with the most positive outcome measures was associated with many positive changes in explanatory factors and the facility with the fewest positive outcome measures experienced negative changes in the same factors. These findings suggest greater SRHP benefits where there was lower NA turnover and agency staffing; less time pressure; and better teamwork, staff communication, and supervisory support.

Implementation and adoption of mechanical patient lift equipment in the hospital setting: The importance of organizational and cultural factors

BACKGROUND

Work focused on understanding implementation and adoption of interventions designed to prevent patient-handling injuries in the hospital setting is lacking in the injury literature and may be more insightful than more traditional evaluation measures.

METHODS

Data from focus groups with health care workers were used to describe barriers and promoters of the adoption of patient lift equipment and a shift to a "minimal-manual lift environment" at two affiliated hospitals.

RESULTS

Several factors influencing the adoption of the lift equipment and patient-handling policy were noted: time, knowledge/ability, staffing, patient characteristics, and organizational and cultural aspects of work. The adoption process was complex, and considerable variability by hospital and across units was observed.

CONCLUSIONS

The use of qualitative data can enhance the understanding of factors that influence implementation and adoption of interventions designed to prevent patient-handling injuries among health care workers.

Objective measures of adoption of patient lift and transfer devices to reduce nursing staff injuries in the hospital setting

BACKGROUND

Interventions to reduce patient-handling injuries in the hospital setting are often evaluated based on their effect on outcomes such as injury rates. Measuring intervention adoption could address how and why observed trends in the outcome occurred.

METHODS

Unit-level data related to adoption of patient lift equipment were systematically collected at several points in time over 5 years on nursing units at two hospitals, including hours of lift equipment use, equipment accessibility, and supply purchases and availability.

RESULTS

Various measures of adoption highlighted the adoption process' gradual nature and variability by hospital and between units. No single measure adequately assessed adoption. Certain measures appear well-correlated.

CONCLUSION

Future evaluation of primary preventive efforts designed to prevent patient-handling injuries would be strengthened by objective data on intermediate measures that reflect intervention implementation and adoption.

Manual material handling advice and assistive devices for preventing and treating back pain in workers

BACKGROUND

Training and the provision of assistive devices are considered major interventions to prevent back pain and its related disability among workers exposed to manual material handling (MMH).

OBJECTIVES

To determine the effectiveness of MMH advice and training and the provision of assistive devices in preventing and treating back pain.

SEARCH STRATEGY

We searched CENTRAL (The Cochrane Library 2011, issue 1), MEDLINE, EMBASE, CINAHL, Nioshtic, CISdoc, Science Citation Index, and PsychLIT to February 2011.

SELECTION CRITERIA

We included randomised controlled trials (RCT) and cohort studies with a concurrent control group that were aimed at changing human behaviour in MMH and measured back pain, back pain-related disability or sickness absence.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted the data and assessed the risk of bias using the criteria recommended by the Cochrane Back Review Group for RCTs and MINORS for the cohort studies.We based the results and conclusions on the analysis of RCTs only. We compared these with the results from cohort studies.

MAIN RESULTS

We included nine RCTs (20,101 employees) and nine cohort studies (1280 employees) on the prevention of back pain in this updated review. Studies compared training to no intervention (4), professional education (2), a video (3), use of a back belt (3) or exercise (2). Other studies compared training plus lifting aids to no intervention (3) and to training only (1). The intensity of training ranged from a single educational session to very extensive personal biofeedback.Six RCTs had a high risk of bias.None of the included studies showed evidence of a preventive effect of training on back pain.There was moderate quality evidence from seven RCTs (19,317 employees) that those who received training reported levels of back pain similar to those who received no intervention, with an odds ratio of 1.17 (95% confidence intervals (CI) 0.68 to 2.02) or minor advice (video), with a relative risk of 0.93 (95% CI 0.69 to 1.25). Confidence intervals around the effect estimates were still wide due to the adjustment for the design effect of clustered studies.The results of the cohort studies were similar to those of the randomised studies.

AUTHORS' CONCLUSIONS

There is moderate quality evidence that MMH advice and training with or without assistive devices does not prevent back pain or back pain-related disability when compared to no intervention or alternative interventions. There is no evidence available from RCTs for the effectiveness of MMH advice and training or MMH assistive devices for treating back pain. More high quality studies could further reduce the remaining uncertainty.

Reported occupational injuries at Swedish recycling centres - based on official statistics

Swedish recycling centres are manned facilities for waste collection. There is no special category in the official injury statistics for employees at recycling centres, which precludes a straightforward analysis of reported occupational injuries. This study aimed at identifying the frequency of reported accidents and diseases and the type of events that contribute to such injuries at recycling centres, based on official injury statistics. The employees were identified as being affected by more than three to five times as many accidents compared with the total workforce in Sweden. The reported accidents had occurred during a wide range of situations, but most frequently during manual handling of waste. Reported work-related diseases were mostly associated with musculoskeletal disorders, mainly due to heavy lifting. A more detailed classification of sanitation professions and workplaces in the official injury statistics would facilitate future studies of injuries in a specific professional category, e.g. employees at recycling centres. Suggestions for prevention are given. STATEMENT OF RELEVANCE: The present article describes all reported work accidents and diseases among employees at recycling centres from 1992 to February 2005. It also highlights the problem of identifying new working groups in the official statistics and gives advice for a detailed classification to facilitate such future studies of injuries.

Nursing staff's movement awareness, attitudes and reported behaviour in patient transfer before and after an educational intervention

The objective was to evaluate changes after a two half-day patient transfer course regarding nursing staff's movement and body awareness, attitudes, reported behaviour, strain, disorder and sick leave. The course aimed at increasing staff's self-awareness of movements and body, and their communication competence, with the intention to promote the patient's independent mobility. Ninety-nine staff in an intervention group and 77 staff in two control groups answered a questionnaire before and after the intervention. After one year there was a significant increase in the number of instructions given and nursing staff's movement awareness in the intervention group compared to the control group. Reported physical disorders decreased significantly in the intervention group compared with both control groups. Increased movement awareness and frequent use of instructions during transfers may encourage patients to move independently and thereby reduce the strain in nursing staff.

Occupational safety and health interventions to reduce musculoskeletal symptoms in the health care sector

INTRODUCTION

Health care work is dangerous and multiple interventions have been tested to reduce the occupational hazards.

METHODS

A systematic review of the literature used a best evidence synthesis approach to address the general question "Do occupational safety and health interventions in health care settings have an effect on musculoskeletal health status?" This was followed by an evaluation of the effectiveness of specific interventions.

RESULTS

The initial search identified 8,465 articles, for the period 1980-2006, which were reduced to 16 studies based on content and quality. A moderate level of evidence was observed for the general question. Moderate evidence was observed for: (1) exercise interventions and (2) multi-component patient handling interventions. An updated search for the period 2006-2009 added three studies and a moderate level of evidence now indicates: (1) patient handling training alone and (2) cognitive behavior training alone have no effect on musculoskeletal health. Few high quality studies were found that examined the effects of interventions in health care settings on musculoskeletal health.

CONCLUSIONS

The findings here echo previous systematic reviews supporting exercise as providing positive health benefits and training alone as not being effective. Given the moderate level of evidence, exercise interventions and multi-component patient handling interventions (MCPHI) were recommended as practices to consider. A multi-component intervention includes a policy that defines an organizational commitment to reducing injuries associated with patient handling, purchase of appropriate lift or transfer equipment to reduce biomechanical hazards and a broad-based ergonomics training program that includes safe patient handling and/or equipment usage. The review demonstrates MCPHI can be evaluated if the term multi-component is clearly defined and consistently applied.

Working conditions at recycling centres in Sweden--physical and psychosocial work environment

The number of jobs at recycling centres are increasing, at the same time as there are indications of work environment problems. The aim of this paper was to investigate physical and psychosocial working conditions for employees at recycling centres in Sweden, to describe how they were perceived, to compare differences between subgroups, and further to identify proposals for improvement. Employees at 42 recycling centres (n=122) responded a postal questionnaire. Of these 32 employees from 16 recycling centres were interviewed, as also their employer (n=16). The work at recycling centres was reported to be a meaningful service job comprising many social interactions with users, but also substantial physical strain. There was a high frequency of injuries and minor injuries. Several risks were identified. There is a need for several preventive actions, e.g. better planning when building recycling centres, including better machines and equipment and more training, especially in handling hazardous waste.

Joint investigation of working conditions, environmental and system performance at recycling centres--development of instruments and their usage

Recycling is a new and developing industry, which has only been researched to a limited extent. This article describes the development and use of instruments for data collection within a multidisciplinary research programme "Recycling centres in Sweden - working conditions, environmental and system performance". The overall purpose of the programme was to form a basis for improving the function of recycling centres with respect to these three perspectives and the disciplines of: ergonomics, safety, external environment, and production systems. A total of 10 instruments were developed for collecting data from employees, managers and visitors at recycling centres, including one instrument for observing visitors. Validation tests were performed in several steps. This, along with the quality of the collected data, and experience from the data collection, showed that the instruments and methodology used were valid and suitable for their purpose.

Effects of a Multifaceted Minimal-Lift Environment for Nursing Staff: Pilot Results

Nursing staff are at risk for musculoskeletal injuries because of the physical nature of patient handling. The purpose of this study is to examine the effectiveness of a multifaceted minimal-lift environment on reported equipment use, musculoskeletal injury rates, and workers’ compensation costs for patient-handling injuries. The pilot study consists of a mixed measures design, with both descriptive and quasi-experimental design elements. The intervention consists of engineering (minimal-lift equipment), administrative (nursing policy), and behavioral (peer coach program) controls. The comparison nursing unit has received engineering controls only. The convenience sample includes nursing staff employed on two medical-surgical nursing units, who provide direct patient care at least 50% of the time. Nursing staff employed in a multifaceted lift environment report greater lift equipment use and experience less injury, with reduced worker’s compensation costs.

Little effect of transfer technique instruction and physical fitness training in reducing low back pain among nurses: a cluster randomised intervention study

The aim of this study was to evaluate the effect of a transfer technique education programme (TT) alone or in combination with physical fitness training (TTPT) compared with a control group, who followed their usual routine. Eleven clinical hospital wards were cluster randomised to either intervention (six wards) or to control (five wards). The intervention cluster was individually randomised to TT (55 nurses) and TTPT (50 nurses), control (76 nurses). The transfer technique programme was a 4-d course of train-the-trainers to teach transfer technique to their colleagues. The physical training consisted of supervised physical fitness training 1 h twice per week for 8 weeks. Implementing transfer technique alone or in combination with physical fitness training among a hospital nursing staff did not, when compared to a control group, show any statistical differences according to self-reported low back pain (LBP), pain level, disability and sick leave at a 12-month follow-up. However, the individual randomised intervention subgroup (transfer technique/physical training) significantly improved the LBP-disability (p = 0.001). Although weakened by a high withdrawal rate, teaching transfer technique to nurses in a hospital setting needs to be thoroughly considered. Other priorities such as physical training may be taken into consideration. The current study supports the findings of other studies that introducing transfer technique alone has no effect in targeting LBP. However, physical training seems to have an influence in minimising the LBP consequences and may be important in the discussion of how to prevent LBP or the recurrence of LBP among nursing personnel.

Nurses' Expectations, Experiences and Attitudes towards the Intervention of a ‘No Lifting Policy’

The aim of the study was to evaluate expectations and attitudes towards a No Lifting Policy programme, the "No Lift system", among nurses at hospitals where an introduction of the intervention was planned (PreNLS hospitals), and to make a comparison with nurses' experiences and attitudes at one hospital where the intervention had already been implemented (NLS hospital). A cross-sectional study of nurses at two PreNLS hospitals and one NLS hospital was performed. Most nurses at both the PreNLS hospitals and the NLS hospital were positive or very positive to the intervention. The expected and experienced obstacles differed between nurses at the PreNLS hospitals and the NLS hospital; however, there was more agreement concerning benefits. The most frequently expected obstacles at the PreNLS hospitals were organisational issues and obstacles related to the facilities, while most obstacles identified at the NLS hospital concerned specific transfers or were patient-related. A decrease in the number of injuries was the most often considered benefit among most nurses. Nurses at the NLS hospital rated their physical exertion as lower in seven out of nine specific patient transfers compared with nurses at the PreNLS hospitals. They also reported increased well-being at work and an improved ability to manage their daily work. The comprehensive approach and participatory design, including all levels of staff and extensive support from the nurses' own union and management, is probably one important explanation for the positive attitudes and successful introduction of the intervention.
