Ergonomic practices within patient care units are associated with musculoskeletal pain and limitations

Who do you ask? predicting injury rates from survey responses

BACKGROUND

Few studies have addressed whether using manager or worker perceptions of safety policies and practices alone predict reported injury rates less accurately than using both.

OBJECTIVE

This study provides an example and describes a method that can be used to address this issue with survey instruments designed to measure safety climate, policies, or practices.

METHODS

Using multilevel logistic regression, we estimated the relationship between worker and manager perceptions of a given exposure and the odds of worker injury during the post-survey year for three safety scales. We tested whether surveying both workers and managers provides additional predictive value compared with surveying just one group.

RESULTS

Injury in the year following the survey was significantly associated with worker scores on two of the three scales. Manager responses were not significantly associated with injury and did not significantly improve injury rate prediction when added to a model with only worker survey responses.

CONCLUSIONS

The capacity of manager-only or worker-only perceptions of safety policies and practices to predict worker injuries should be established before choosing to survey just one or the other. The approach and findings in this paper can be applied to other survey instruments and in other settings to help make this choice.

The Tech4Rest Randomized Controlled Trial: Applying the Hierarchy of Controls to Advance the Sleep, Health, and Well-being of Team Truck Drivers

OBJECTIVE

The aim of the study was to evaluate the effectiveness of interventions to improve sleep, reduce fatigue, and advance the well-being of team truck drivers.

METHODS

In a randomized controlled trial ( k = 24 teams; N = 49 drivers; 61.3% of planned sample), intervention teams were exposed to baseline (3-4 weeks), cab enhancements (active suspension seat, therapeutic mattress; 3-4 weeks), and cab enhancements plus a behavioral sleep-health program (1-2 months). Control teams worked as usual during the same period.

RESULTS

Trends in sleep-related outcomes favored the intervention. Large and statistically significant intervention effects were observed for objectively measured physical activity (a behavioral program target). The discussion of results addresses effect sizes, statistical power, intervention exposure, and work organization.

CONCLUSIONS

Trends, effect sizes, and significant findings in this rare trial provide valuable guidance for future efforts to improve working conditions and outcomes for team drivers.

Underreporting of work-related low back pain among registered nurses: A mixed method study

BACKGROUND

Identifying and addressing work-related health problems early is crucial, but workers often perceive barriers in reporting these to management. This study aimed to investigate the factors associated with nurses' reporting of work-related low back pain to their managers and explored the reasons why nurses with patient handling injuries did not report them.

METHODS

This study is a concurrent mixed-method analysis of data from two statewide cross-sectional surveys of California registered nurses conducted in 2013 and 2016. The reporting of work-related low back pain to management (n = 288) was examined for associations with individual, occupational, and organizational factors. For qualitative analysis, the reasons for not reporting patient handling injuries were explored using open-ended responses (n = 42).

RESULTS

Reporting was associated with BIPOC (Black, Indigenous, and People of Color) men (adjusted odds ratio [AOR]: 1.31, 95% confidence interval [CI]: 1.07-1.59) compared to non-Hispanic White women; being a non-US educated nurse (AOR: 0.90, 95% CI: 0.80-1.01); experiencing greater low back pain (AOR: 1.07, 95% CI: 1.02-1.12); missing work (AOR: 1.38, 95% CI: 1.21-2.62); perceiving high physical workload (AOR: 0.89, 95% CI: 0.81-0.98); perceiving high people-oriented culture (AOR: 1.14, 95% CI: 1.04-1.25); and perceiving high ergonomic practices (AOR: 0.89, 95% CI: 0.81-0.98). Identified themes on the reasons for not reporting injuries included organizational-culture attitudes toward work-related injuries and injury characteristics of musculoskeletal disorders.

CONCLUSIONS

The findings indicate a need for management to remove structural barriers and improve organizational practices, and for a culture that promotes trust and open communication between workers and management.

COMMunity of Practice And Safety Support for Navigating Pain (COMPASS-NP): study protocol for a randomized controlled trial with home care workers

BACKGROUND

Chronic pain is a prevalent and costly problem that often has occupational origins. Home care workers (HCWs) are at high risk for work-related injuries, pain, and disability. Current treatments for chronic pain emphasize medications, which are an inadequate stand-alone treatment and can produce significant adverse effects.

METHODS

In this translational study, we will adapt an established work-based injury prevention and health promotion program (COMmunity of Practice And Safety Support: COMPASS) to address the needs of HCWs experiencing chronic pain. COMPASS employs peer-led, scripted group meetings that include educational content, activities, goal setting, and structured social support. The translated intervention, named COMPASS for Navigating Pain (COMPASS-NP), will be delivered in an online group format. Safety protections will be strengthened through an ergonomic self-assessment and vouchers for purchasing ergonomic tools. Educational content will integrate a self-management approach to chronic pain using proven cognitive-behavioral therapy (CBT) principles. We will use a mixed-methods hybrid type 2 evaluation approach to assess effectiveness and implementation. A cluster-randomized waitlist control design will involve 14 groups of 10 HCWs (n = 140) recruited from Washington, Oregon, and Idaho. Half of the groups will be randomly selected to complete the intervention during the first 10 weeks, while the waitlist groups serve as controls. During weeks 10-20, the waitlist groups will complete the intervention while the original intervention groups complete a follow-up period without further intervention. Our primary hypothesis is that COMPASS-NP will reduce pain interference with work and life. Secondary outcomes include injury and pain prevention behaviors, pain severity, changes in medication use, risk for opioid misuse, well-being, physical activity, and sleep. Qualitative data, including phone interviews with group facilitators and organizational partners, will evaluate the implementation and guide dissemination.

DISCUSSION

The results will advance the use and knowledge of secondary prevention interventions such as ergonomic tools and cognitive behavior therapy, to reduce injury, pain, and disability and to encourage appropriate uses of analgesic medications among HCWs.

Course Design and Learning Outcomes of a Practical Online Ergonomics Course for Surgical Residents

OBJECTIVE

Course content was designed and the learning outcomes assessed for an online ergonomics course for surgical residents. This course could fulfill an optional Surgical Council on Resident Education (SCORE) curriculum on Surgical Ergonomics.

DESIGN

The online course included five 5-minute modules within the residents' learning system, each ending with an ungraded knowledge question, and a final 5-question multiple-choice retention quiz that allowed infinite attempts. The course was designed by ergonomists and surgeons at a quaternary academic hospital system. Participants were given two weeks to complete the modules. An electronic survey with questions assessing ergonomics knowledge and understanding on a 5-point Likert scale (strongly disagree - strongly agree) was distributed both before and after the course. The post-course survey included three additional questions to elicit feedback regarding learning experience and course design. Descriptive statistics and nonparametric paired comparisons were used to evaluate learning outcomes.

SETTING

General surgery residency program at an academic medical center in the U.S.

PARTICIPANTS

Twenty-two general surgery post graduate year 1 residents (PGY1s) were recruited to participate and completed the pre-course survey. Eight out of the 22 participants (36%) completed the online course and quiz; seven (32%) completed the course, quiz, and the post-course survey.

RESULTS

Participants had high pre-course awareness of the importance of surgical ergonomics, benefits of work-related musculoskeletal disorder (WMSD) prevention, as well as awkward intraoperative postures being an WMSD risk factor. Participants' confidence increased significantly from pre- to post-course in ability to assess risk (p = 0.021), but not in ability or willingness to mitigate risky surgical postures. Participants who completed the quiz answered a median of 4 (IQR: [4, 5]) questions correctly. All participants indicated that they would recommend this course to other residents.

CONCLUSIONS

These short practical ergonomics online learning modules increased surgical residents' confidence in assessing surgical WMSD risks.

Evaluating the Current State of Ergonomics Education Offered to Students in US Medical Students

BACKGROUND

The high rate of work-related musculoskeletal disorders (WMSD) among surgeons is well-documented and found to factor into medical students' interest in surgical specialties. Ergonomic techniques can reduce musculoskeletal pain in surgeons. Access to ergonomics education in residency is minimal and the ergonomics education offered in medical school has not been characterized.

METHODS

An anonymous, online survey was distributed to 210 administrators in medical education and curriculum at all accredited US allopathic medical schools. They were asked about their knowledge of ergonomics, assessment of potential benefits of ergonomics education to their students, and the ergonomics education offered at their institution.

RESULTS

A total of 71 surveys were completed (33.8% response rate). 82% of schools reported familiarity with the study of ergonomics and 81% thought it would be beneficial to the future careers of their students to receive ergonomics education. Respondents estimated 43% of surgeons experience WMSDs and those that did not think ergonomics education would be beneficial to their students' future careers had a statistically significantly lower estimate of WMSD burden amongst practicing surgeons. Only one respondent reported that students at their institution receive greater than three hours of ergonomics education, while 98% reported their students will receive less than three hours. Considering this, 81% of respondents reported that students do have access to other resources that encourage ergonomic practices, such as gym access, yoga classes, and surgical simulation labs.

DISCUSSION

Medical schools should increase access to ergonomics education and integrate it into their curriculum as early as possible.

Does Postural Feedback Reduce Musculoskeletal Risk?: A Randomized Controlled Trial

Background: There is a high prevalence of musculoskeletal disorders among personnel working in the healthcare sector, mainly among nursing assistants and orderlies. Objective: The objective is to analyze the effectiveness of a multi-component intervention that included postural feedback in reducing musculoskeletal risk. Method: A total of 24 nursing assistants and orderlies in a hospital setting were randomly assigned to an intervention group or a control group. After collecting sociodemographic information, a selection of tasks was made and assessed using the REBA (rapid entire body assessment) method. A multi-component intervention was designed combining theoretical and practical training, including feedback on the postures performed by the professionals involved, especially those involving high musculoskeletal risk. This program was applied only to participants in the intervention group. Subsequently, eight months after the first assessment and intervention, the second assessment was carried out using the same method and process as in the first evaluation. Results: The results indicate that the musculoskeletal risk in the second assessment in the intervention group was significantly reduced. However, no significant changes were observed in the control group. Conclusion: The multi-component intervention applied can significantly reduce the musculoskeletal risk of nursing assistants and orderlies. In addition, it is a low-cost intervention with great applicability.

The active workplace study: Protocol for a randomized controlled trial with sedentary workers

OBJECTIVES

Sedentary behavior is pervasive in the workplace and is harmful to health. Research on the effectiveness of comprehensive workplace interventions to reduce sedentary behavior and improve worker health and safety is crucial as sedentary jobs become more common.

METHODS

We developed a Total Worker Health intervention targeting sedentary behavior in call centers, and are evaluating intervention effectiveness in a randomized controlled trial. Four worksites will be randomly assigned to an intervention or control condition. The intervention condition includes the provision of active workstations along with programs and procedures at environmental, organizational, and individual levels. Control worksites will receive active workstations with no additional support, following common organizational practices.

RESULTS

Outcomes include objectively measured physical activity, biological markers of health, and self-report survey data at baseline, after the 6-month intervention or control period, and at a 12-month follow-up.

CONCLUSIONS

The aims of the study are to determine whether a Total Worker Health intervention has stronger impacts on workplace sedentary behavior, uninterrupted bouts of sitting, and worker health and safety compared to a usual practice control condition. The study will inform future workplace sedentary behavior intervention and dissemination research, along with organizational best practices for reducing sedentary behavior in the workplace.

Assessing the potential for "undesired" effects of passive back-support exoskeleton use during a simulated manual assembly task: Muscle activity, posture, balance, discomfort, and usability

Back-support exoskeletons (BSEs) are wearable systems designed to reduce physical demands on the back, but which could have undesired effects beyond this design intention. Participants (n = 18) used two commercial BSEs to complete a brief (~15-20 s) simulated manual assembly task in varying conditions, with outcome measures that included: working posture, activity levels in "secondary" muscle groups (shoulders and thighs), perceived balance, discomfort, and usability. Using a BSE led to small and inconsistent changes in working postures (e.g., < ~14° change in lumbar flexion), muscular activity in the secondary muscle groups (<±2% of maximum voluntary isometric contractions), or perceived balance. Limitations in movement were reported for both BSEs, however, along with moderate levels of discomfort. Task-specific responses were evident for all outcome measures, though these depended on the specific BSE used and differed between genders in many cases. Future work should focus on interactions between a given user, BSE design, and task conditions.

Safe patient handling legislation and changes in programs, practices, perceptions, and experience of musculoskeletal disorders by hospital characteristics: A repeated cross-sectional survey study

BACKGROUND

Safe patient handling legislation has been enacted in 11 states in the United States to protect healthcare workers from patient handing injuries. Implementations and outcomes may vary across hospitals by the characteristics of the institution.

OBJECTIVES

This study was to investigate the changes in safe patient handling programs in hospitals, and nurses' perceptions, work practices, and musculoskeletal symptoms by hospital characteristics after the passage of California's safe patient handling legislation.

DESIGN

Repeated cross-sectional surveys.

SETTINGS

Two statewide surveys of registered nurses were conducted in California, where a safe patient handling law became effective in 2012. Random samples were selected from the lists of the California Board of Registered Nurses (2000 nurses in 2013 and 3000 nurses in 2016).

PARTICIPANTS

Among survey respondents (26% in 2013 and 20% in 2016), the study sample included 254 nurses in 2013 and 281 nurses in 2016, who met the eligibility for this study: nurses employed in a hospital and had direct patient care or patient handling duties.

METHODS

Data were collected by postal and on-line surveys. Data were compared by hospital size, geographic area, hospital teaching status, and ownership (for-profit, non-profit, government).

RESULTS

Between 2013 and 2016, nurses' reports showed improvements in safe patient handling policies and programs across the different characteristics of hospitals. In 2016, nurses in large, teaching, non-profit, and rural hospitals reported slightly better scores for safe patient handling program variables than their counterparts; however, changes in the use of mechanical lifting devices and experiences of musculoskeletal symptoms and injury were not significantly different by hospital characteristics. Overall, teaching hospitals consistently showed greater improvements than non-teaching hospitals for both hospital-level (safe patient handling programs and organizational practices) and individual-level (perceptions and symptoms) variables.

CONCLUSIONS

Our findings indicate overall improvements of safe patient handling programs in California hospitals after the passage of safe patient handling legislation. Positive changes appear to be greater among teaching, non-profit, and rural hospitals. However, greater positive changes in safe patient handling programs shown in certain hospital characteristics were not necessarily linked to more improvements in nurses' safe work practices and experiences of musculoskeletal symptoms or injuries.

Challenging Aggressive Behaviors Experienced by Personal Support Workers in Comparison to Home Care Workers: Relationships between Caregiver Experiences and Psychological Health

Personal support workers (PSW) are caregivers for children and adults with intellectual and developmental disabilities (IDDs) or adults experiencing mental illness or other behavioral health conditions. The work can be very meaningful, but many PSWs must prepare for, monitor, and manage challenging behaviors, including aggression. This study was designed to estimate the prevalence of aggression experienced by PSWs in Oregon, and compare it to a previous sample of Oregon home care workers (HCWs). This comparison included an analysis of relationships between exposures to aggression and psychological health factors. PSWs in Oregon (N = 240) were surveyed electronically at a single time point. PSWs generally reported higher rates of exposure to aggression compared to HCWs. Experiences with aggression were positively associated with fatigue and weakly associated with depression, but not stress. PSWs' self-reported lost work time injury rate was elevated compared to the US average, but it was comparable to previous self-reported injury rates from HCWs. Physical demands of work were the most prevalent reported primary safety concern, followed by challenging behaviors (including aggression). Developing tailored training to help PSWs understand, plan for, minimize, and manage challenging behaviors is a social priority.

The Current State of Surgical Ergonomics Education in U.S. Surgical Training: A Survey Study

OBJECTIVE

The aim of this study was to characterize the current state of surgical ergonomics education in the United States.

BACKGROUND

The burden of work-related musculoskeletal disorders (MSDs) in surgeons is high and no overarching strategy for redress exists. Twelve distinct specialties describe an unmet need for surgical ergonomics education (SEE). This study aimed to define the current state of SEE in U.S. surgical training programs.

METHODS

We performed a descriptive analysis of a 20-item questionnaire of ACGME-certified program directors from 14 surgical and interventional medical specialties. Formal SEE was defined as any organized education module that reviewed the occupation-specific burden of common work-related MSDs and described a framework for prevention via occupation-specific applied ergonomics. Program directors were queried regarding SEE provision, characteristics, and perceived trainee attitude toward the education.

RESULTS

Questionnaires were received from 130 of 441 (29.5%) program directors. Two (1.5%) provided formal SEE and 33 (25.4%) provided informal SEE, which consisted of unstructured intraoperative directives and isolated lectures. Two programs previously provided SEE but discontinued the effort due to lack of an evidence-based framework and instructors. Trainees appeared to think that learning surgical ergonomics skills was a worthwhile time investment in 100% and 76.7% of current formal and informal SEE, respectively.

CONCLUSION

SEE is rarely provided in any capacity (25.4%), let alone in a consistent or evaluable fashion (1.5%). Impediments to sustainable SEE include lack of an evidence-based framework for education and instructors. An evidence-based, reproducible, and accreditation council-compliant SEE module would be a valuable resource for the surgical and interventional medical communities.

Comparison of lift use, perceptions, and musculoskeletal symptoms between ceiling lifts and floor-based lifts in patient handling

Lifting equipment can reduce the risk of injury from patient handling, but limited availability and adoption have been a persistent problem. Data from statewide surveys of California nurses (N = 389) in 2013 and 2016 were analyzed to evaluate lift use, perceptions about lifts and injury risk, and musculoskeletal symptoms by type of available lifts. Nurses with ceiling lifts (23%) were significantly more likely to use lifts and had more positive perceptions about lifts, regarding worker safety, patient safety and comfort, ease of use, access, and storing, than nurses with only floor lifts (77%). Nurses with ceiling lifts reported less low back pain and shoulder pain. Our study findings suggest that providing ceiling lifts can result in superior outcomes to floor-based lifts in multiple aspects, including better acceptance and use by nurses for patient handling, as well as being associated with reduced work-related musculoskeletal symptoms in the low back and shoulders.

Total Worker Health® Intervention for Construction Workers Alters Safety, Health, Well-Being Measures

OBJECTIVE

The aim of this study was to evaluate the effectiveness of a 14-week Total Worker Health (TWH) intervention designed for construction crews.

METHODS

Supervisors (n = 22) completed computer-based training and self-monitoring activities on team building, work-life balance, and reinforcing targeted behaviors. Supervisors and workers (n = 13) also completed scripted safety and health education in small groups with practice activities.

RESULTS

The intervention led to significant (P < 0.05) improvements in family-supportive supervisory behaviors (d = 0.72). Additional significant improvements included reported frequency of exercising 30 minutes/day and muscle toning exercise (d = 0.50 and 0.59), family and coworker healthy diet support (d = 0.53 and 0.59), team cohesion (d = 0.38), reduced sugary snacks and drinks (d = 0.46 and d = 0.46), sleep duration (d = 0.38), and objectively-measured systolic blood pressure (d = 0.27).

CONCLUSION

A TWH intervention tailored for construction crews can simultaneously improve safety, health, and well-being.

Literature Review of Policy Implications From Findings of the Center for Work, Health, and Well-being

OBJECTIVE

To review the publications of a Total Worker Health Center of Excellence, the Harvard T.H. Chan School of Public Health Center for Work, Health, and Well-being, in order to identify research findings relevant to either organizational or public policies.

METHODS

Two researchers independently reviewed 57 publications from 2011 to 2019 to identify cross-cutting themes that focus on working conditions or related health outcomes and their organizational and public policy implications.

RESULTS

Twelve cross-cutting themes were identified with their respective organizational and public policy implications. Several policy implications cut across work-related themes.

CONCLUSIONS

Policy implications of TWH research will aid in setting priorities to translate this from research into practice in future studies and help identify gaps that we and others can use to plan future TWH research.

Paradoxical Impact of a Patient-Handling Intervention on Injury Rate Disparity Among Hospital Workers

OBJECTIVES

To test whether a comprehensive safe patient-handling intervention, which successfully reduced overall injury rates among hospital workers in a prior study, was differentially effective for higher-wage workers (nurses) versus low-wage workers (patient care associates [PCAs]).

METHODS

Data were from a cohort of nurses and PCAs at 2 large hospitals in Boston, Massachusetts. One hospital received the intervention in 2013; the other did not. Using longitudinal survey data from 2012 and 2014 plus longitudinal administrative injury and payroll data, we tested for socioeconomic differences in changes in self-reported safe patient-handling practices, and for socioeconomic differences in changes in injury rates using administrative data.

RESULTS

After the intervention, improvements in self-reported patient-handling practices were equivalent for PCAs and for nurses. However, in administrative data, lifting and exertion injuries decreased among nurses (rate ratio [RR] = 0.64; 95% confidence interval [CI] = 0.41, 1.00) but not PCAs (RR = 1.10; 95% CI = 0.74,1.63; P for occupation × intervention interaction = 0.02).

CONCLUSIONS

Although the population-level injury rate decreased after the intervention, most improvements were among higher-wage workers, widening the socioeconomic gap in injury and exemplifying the inequality paradox. Results have implications for public health intervention development, implementation, and analysis.

Claim Costs, Musculoskeletal Health, and Work Exposure in Physical Therapists, Occupational Therapists, Physical Therapist Assistants, and Occupational Therapist Assistants: A Comparison Among Long-Term Care Jobs

BACKGROUND

Patient/resident-handling tasks are physically demanding and associated with musculoskeletal disorders (MSDs) among nursing personnel. The routine performance of such tasks by physical therapists and occupational therapists during treatment can cause similar problems.

OBJECTIVE

This study characterized the magnitude of MSDs and the risk factors for MSDs in physical therapists, occupational therapists, physical therapist assistants, and occupational therapist assistants (collectively called "therapy personnel" for this study) and compared them with those of other nursing home workers, especially nursing staff.

DESIGN

This was a cross-sectional study.

METHODS

Workers' compensation claim (WCC) data from 1 year of experience in a long-term care company were used to compute claim rates by body region, nature, and cause of injury, and the costs per case and per full-time-equivalent employee. Data regarding musculoskeletal symptoms, use of patient/resident-lifting equipment, and perceived physical and psychological job demands were obtained from a concurrent cross-sectional survey of workers from 24 long-term care facilities.

RESULTS

About 80% of the WCCs were related to musculoskeletal incidents in nursing aides and therapy personnel. WCC costs paid per case for therapy personnel were more than twice those for nursing staff for both ergonomic and resident-handling incidents. Prevalence of low back pain in therapy personnel was the same as in nursing aides (48%) but involved more chronic, milder pain. About half of therapy personnel reported "never" or "rarely" using patient/resident-lifting equipment. Therapy personnel, nursing aides, and housekeeping/dietary/maintenance personnel reported the highest physical job demands.

LIMITATIONS

Causal inference cannot be determined due to the cross-sectional nature of the survey data. Study findings are relevant only to therapy work in long-term care settings because exposures vary in other health care settings (hospitals, outpatient, and others).

CONCLUSIONS

MSD prevalence and claim costs in therapy personnel are high enough to deserve more attention. The low use of patient/resident-lifting equipment in therapy could increase the risk for MSDs. Future studies with comprehensive ergonomic analysis of therapist tasks and recommendations to reduce injuries are warranted.

The relationship between organizational policies and practices and work limitations among hospital patient care workers

OBJECTIVE

We examined relationships between organizational policies and practices (OPPs) (safety practices, ergonomic practices, and people-oriented culture) and work limitations in a sample of hospital workers.

METHODS

We used the 6-item Work Limitations Questionnaire (WLQ) to assess workers' perceptions of health-related work limitations. Self-reported OPPs and the WLQ were collected from workers in Boston, Massachusetts (n = 1277). We conducted random-intercept multi-level logistic regression models for each OPP using stepwise selection of covariates.

RESULTS

As the unit-average ergonomic practice score increased by one, the odds of a worker reporting work limitations decreased by approximately 39% (P-value = 0.018), adjusted for job title, age, and body mass index. A similar relationship existed for people-oriented culture (P-value = 0.038). The association between safety practices and work limitations was similar, but not statistically significant.

CONCLUSIONS

This study demonstrated the importance of workplace OPPs. OPPs that promote positive and supportive environments and that foster improvements in ergonomics may help reduce work limitations.

Do Technical Aids for Patient Handling Prevent Musculoskeletal Complaints in Health Care Workers?-A Systematic Review of Intervention Studies

The physical load ensuing from the repositioning and moving of patients puts health care workers at risk of musculoskeletal complaints. Technical equipment developed to aid with patient handling should reduce physical strain and workload; however, the efficacy of these aids in preventing musculoskeletal disorders and complaints is still unclear. A systematic review of controlled intervention studies was conducted to examine if the risk of musculoskeletal complaints and disorders is reduced by technical patient handling equipment. MEDLINE®/PubMed®, EMBASE®, Allied and Complementary Medicine Database (AMED), and Cumulative Index of Nursing and Allied Health Literature (CINAHL®) were searched using terms for nursing, caregiving, technical aids, musculoskeletal injuries, and complaints. Randomized controlled trials and controlled before-after studies of interventions including technical patient handling equipment were included. The titles and abstracts of 9554 publications and 97 full-texts were screened by two reviewers. The qualitative synthesis included one randomized controlled trial (RCT) and ten controlled before-after studies. A meta-analysis of four studies resulted in a pooled risk ratio for musculoskeletal injury claims (post-intervention) of 0.78 (95% confidence interval 0.68-0.90). Overall, the methodological quality of the studies was poor and the results often based on administrative injury claim data, introducing potential selection bias. Interventions with technical patient handling aids appear to prevent musculoskeletal complaints, but the certainty of the evidence according to GRADE approach ranged from low to very low.

Nurses' but not supervisors' safety practices are linked with job satisfaction

AIMS

To test the associations of safety practices as reported by nurses and their respective unit supervisors with job satisfaction.

BACKGROUND

Psychosocial workplace factors are associated with job satisfaction; however, it is unknown whether nurses and supervisors accounts of safety practices are differentially linked to this outcome.

METHODS

Cross-sectional study design including nurses (n = 1052) nested in 94 units in two hospitals in Boston (MA, USA). Safety practices refer to the identification and control of occupational hazards at the unit. Safety practices were measured aggregating nurses' responses per unit, and supervisory levels. Individual's job satisfaction for each nurse was the response variable.

RESULTS

Supervisors assessed safety practices more favourably than their unit nursing staff. Adjusted random intercept logistic regressions showed that the odds of higher job satisfaction were higher for nurses at units with better safety practices (OR: 1.67, 95% CI: 1.04, 2.68) compared with nurses at units that averaged lower safety practices. Supervisors' reports of safety practices were not correlated with the job satisfaction of their staff.

CONCLUSIONS

Adequate safety practices might be a relevant managerial role that enhances job satisfaction among nurses.

IMPLICATIONS FOR NURSING MANAGEMENT

Nursing supervisors should calibrate their safety assessments with their nursing staff to improve nurses' job satisfaction.

An Inspection Tool and Process to Identify Modifiable Aspects of Acute Care Hospital Patient Care Units to Prevent Work-Related Musculoskeletal Disorders

A dearth of practical resources is available for evaluating ergonomic risk factors in dynamic health care work environments. Of particular need are tools for inspecting patient care environments for hazards. The goal of this study was to describe the development and application of an inspection tool and a process for identifying hazards inherent in the modifiable aspects of the physical environment to reduce injury risk to hospital workers. Through an iterative and participatory process, the tool and inspection process were developed with three purposes in mind: (a) create a framework for the inspection of physical work environments and physical conditions of work associated with injury risk (hazards), (b) document the physical conditions, and (c) provide feedback to decision makers. The tool and process were used by an ergonomics researcher on four patient care units as part of the Be Well, Work Well Total Worker Health® intervention. The resulting inspection process provided a structured method for recognizing hazards in the dynamic modifiable physical work environment and reporting both observations and recommendations to decision makers. The development and implementation of the inspection tool provided guidance to modify the physical work environment by implementing ergonomic solutions. The tool allowed the organization to plan and prioritize ergonomic hazard abatement (e.g. resource allocation and tracking trends). Within a Total Worker Health® framework, this tool can measure work practices which can then be used to inform organizational programs and policies within a health care setting.

Lifting and exertion injuries decrease after implementation of an integrated hospital-wide safe patient handling and mobilisation programme

OBJECTIVE

With increasing emphasis on early and frequent mobilisation of patients in acute care, safe patient handling and mobilisation practices need to be integrated into these quality initiatives. We completed a programme evaluation of a safe patient handling and mobilisation programme within the context of a hospital-wide patient care improvement initiative that utilised a systems approach and integrated safe patient equipment and practices into patient care plans.

METHODS

Baseline and 12-month follow-up surveys of 1832 direct patient care workers assessed work practices and self-reported pain while an integrated employee payroll and injury database provided recordable injury rates collected concurrently at 2 hospitals: the study hospital with the programme and a comparison hospital.

RESULTS

Safe and unsafe patient handling practice scales at the study hospital improved significantly (p<0.0001 and p=0.0031, respectively), with no differences observed at the comparison hospital. We observed significant decreases in recordable neck and shoulder (Relative Risk (RR)=0.68, 95% CI 0.46 to 1.00), lifting and exertion (RR=0.73, 95% CI 0.60 to 0.89) and pain and inflammation (RR=0.78, 95% CI 0.62 to 1.00) injury rates at the study hospital. Changes in rates at the comparison hospital were not statistically significant.

CONCLUSIONS

Within the context of a patient mobilisation initiative, a safe patient handling and mobilisation programme was associated with improved work practices and a reduction in recordable worker injuries. This study demonstrates the potential impact of utilising a systems approach based on recommended best practices, including integration of these practices into the patient's plan for care.

Integrating worksite health protection and health promotion: A conceptual model for intervention and research

There is increasing recognition of the value added by integrating traditionally separate efforts to protect and promote worker safety and health. This paper presents an innovative conceptual model to guide research on determinants of worker safety and health and to inform the design, implementation and evaluation of integrated approaches to promoting and protecting worker health. This model is rooted in multiple theories and the premise that the conditions of work are important determinants of individual safety and health outcomes and behaviors, and outcomes important to enterprises such as absence and turnover. Integrated policies, programs and practices simultaneously address multiple conditions of work, including the physical work environment and the organization of work (e.g., psychosocial factors, job tasks and demands). Findings from two recent studies conducted in Boston and Minnesota (2009-2015) illustrate the application of this model to guide social epidemiological research. This paper focuses particular attention on the relationships of the conditions of work to worker health-related behaviors, musculoskeletal symptoms, and occupational injury; and to the design of integrated interventions in response to specific settings and conditions of work of small and medium size manufacturing businesses, based on a systematic assessment of priorities, needs, and resources within an organization. This model provides an organizing framework for both research and practice by specifying the causal pathways through which work may influence health outcomes, and for designing and testing interventions to improve worker safety and health that are meaningful for workers and employers, and responsive to that setting's conditions of work.

Safety and Health Support for Home Care Workers: The COMPASS Randomized Controlled Trial

OBJECTIVES

To determine the effectiveness of the COMmunity of Practice And Safety Support (COMPASS) Total Worker Health intervention for home care workers.

METHODS

We randomized 16 clusters of workers (n = 149) to intervention or usual-practice control conditions. The 12-month intervention was scripted and peer-led, and involved education on safety, health, and well-being; goal setting and self-monitoring; and structured social support. We collected measures at baseline, 6 months, and 12 months, which included workers' experienced community of practice (i.e., people engaged in a common activity who interact regularly for shared learning and improvement). Implementation occurred during 2013 and 2014 in Oregon.

RESULTS

In an intent-to-treat analysis, relative to control, the intervention produced significant and sustained improvements in workers' experienced community of practice. Additional significant improvements included the use of ergonomic tools or techniques for physical work, safety communication with consumer-employers, hazard correction in homes, fruit and vegetable consumption, lost work days because of injury, high-density lipoprotein cholesterol, and grip strength. Consumer-employers' reports of caregiver safety behaviors also significantly improved.

CONCLUSIONS

COMPASS was effective for improving home care workers' social resources and simultaneously impacted both safety and health factors.

Implementing an Integrated Health Protection/Health Promotion Intervention in the Hospital Setting: Lessons Learned From the Be Well, Work Well Study

OBJECTIVE

This study reports findings from a proof-of-concept trial designed to examine the feasibility and estimates the efficacy of the "Be Well, Work Well" workplace intervention.

METHODS

The intervention included consultation for nurse managers to implement changes on patient-care units and educational programming for patient-care staff to facilitate improvements in safety and health behaviors. We used a mixed-methods approach to evaluate feasibility and efficacy.

RESULTS

Using findings from process tracking and qualitative research, we observed challenges to implementing the intervention due to the physical demands, time constraints, and psychological strains of patient care. Using survey data, we found no significant intervention effects.

CONCLUSIONS

Beyond educating individual workers, systemwide initiatives that respond to conditions of work might be needed to transform the workplace culture and broader milieu in support of worker health and safety.

The COMPASS pilot study: a total worker Health™ intervention for home care workers

OBJECTIVE

To develop a team-based Total Worker Health™ (injury prevention + health promotion) intervention for home care workers and estimate intervention effects on workers' well-being and health and safety behaviors.

METHODS

Home care workers (n = 16) met monthly in teams for education and social support using a scripted, peer-led approach. Meeting process measures and pre-/postintervention outcome measures were collected.

RESULTS

Knowledge gains averaged 18.7% (standard deviation = 0.04), and 62.0% (standard deviation = 0.13) of participants reported making safety or health changes between meetings. Workers' well-being improved significantly (life satisfaction, d = 0.65, P < 0.05; negative affect, d = 0.64, P < 0.05), and the majority of other safety and health outcomes changed in expected directions.

CONCLUSIONS

COMPASS is a feasible intervention model for simultaneously preventing injuries and promoting health among home care workers.

Physical activity levels at work and outside of work among commercial construction workers

OBJECTIVE

Characterize the number of minutes of moderate and vigorous physical activities at work and outside of work during seven consecutive days, in a sample of 55 commercial construction workers.

METHODS

Workers wore accelerometers during work and outside-of-work hours for seven consecutive days and completed brief survey at the seventh day of data collection.

RESULTS

From the directly measured physical activity, the average number per participant of moderate minutes of occupational physical activity and physical activity outside of work obtained in short bouts were 243 minutes (65%) and 130 minutes (35%), respectively. Directly measured minutes of vigorous occupational physical activity were significant and positively correlated with self-reported fatigue.

CONCLUSIONS

Among commercial construction workers, physical activity from work contributes significantly, approximately two thirds, toward a worker's total amount of weekly minutes of moderate physical activity.

Impact of organizational policies and practices on workplace injuries in a hospital setting

OBJECTIVE

This study aimed to assess relationships between perceptions of organizational practices and policies (OPP), social support, and injury rates among workers in hospital units.

METHODS

A total of 1230 hospital workers provided survey data on OPP, job flexibility, and social support. Demographic data and unit injury rates were collected from the hospitals' administrative databases.

RESULTS

Injury rates were lower in units where workers reported higher OPP scores and high social support. These relationships were mainly observed among registered nurses. Registered nurses perceived coworker support and OPP as less satisfactory than patient care associates (PCAs). Nevertheless, because of the low number of PCAs at each unit, results for the PCAs are preliminary and should be further researched in future studies with larger sample sizes.

CONCLUSIONS

Employers aiming to reduce injuries in hospitals could focus on good OPP and supportive work environment.

The COMmunity of Practice And Safety Support (COMPASS) Total Worker Health™ study among home care workers: study protocol for a randomized controlled trial

BACKGROUND

Home care workers are a high-risk group for injury and illness. Their unique work structure presents challenges to delivering a program to enhance their health and safety. No randomized controlled trials have assessed the impact of a Total Worker Health™ program designed for their needs.

METHODS/DESIGN

The COMPASS (COMmunity of Practice And Safety Support) study is a cluster randomized trial being implemented among Oregon's unionized home care workers. Partnering with the Oregon Home Care Commission allowed recruiting 10 pairs of home care worker groups with 8 participants per group (n = 160) for balanced randomization of groups to intervention and control conditions. Physiologic and survey evaluation of all participants will be at enrollment, 6 months and 12 months. Primary outcomes are to increase health promoting (for example, healthy nutrition and regular physical activity) and health protecting (that is, safety) behaviors. In addition to assessing outcomes adjusted for the hierarchical design, mediation analyses will be used to deconstruct and confirm the program's theoretical underpinnings and intervention processes. Intervention groups will participate in a series of monthly 2-hour meetings designed as ritualized, scripted peer-led sessions to increase knowledge, practice skills and build support for healthy actions. Self-monitoring and individual and team level goals are included to augment change. Because generalizability, reach and achieving dissemination are priorities, following initial wave findings, a second wave of COMPASS groups will be recruited and enrolled with tailoring of the program to align with existing Home Care Commission educational offerings. Outcomes, process and mediation of those tailored groups will be compared with the original wave's findings.

DISCUSSION

The COMPASS trial will assess a novel program to enhance the safety and health of a vulnerable, rapidly expanding group of isolated caregivers, whose critical work allows independent living of frail seniors and the disabled.

Worker assessments of organizational practices and psychosocial work environment are associated with musculoskeletal injuries in hospital patient care workers

BACKGROUND

Hospital patient care (PC) workers have high rates of workplace injuries, particularly musculoskeletal injuries. Despite a wide spectrum of documented health hazards, little is known about the association between psychosocial factors at work and OSHA-recordable musculoskeletal injuries.

METHODS

PC-workers (n = 1,572, 79%) completed surveys assessing a number of organizational, psychosocial and psychological variables. Associations between the survey responses and injury records were tested using bivariate and multivariate analyses.

RESULTS

A 5% of the PC-workers had at least one OSHA-recordable musculoskeletal injury over the year, and the injuries were significantly associated with: organizational factors (lower people-oriented culture), psychosocial factors (lower supervisor support), and structural factors (job title: being a patient care assistant).

CONCLUSIONS

The results show support for a multifactorial understanding of musculoskeletal injuries in hospital PC-workers. An increased focus on the various dimensions associated with injury reports, particularly the organizational and psychosocial factors, could contribute to more efficient interventions and programs.

The impact of workplace factors on filing of workers' compensation claims among nursing home workers

Background

Injuries reported to workers’ compensation (WC) system are often used to estimate incidence of health outcomes and evaluate interventions in musculoskeletal epidemiology studies. However, WC claims represent a relatively small subset of all musculoskeletal disorders among employed individuals, and perhaps not a representative subset. This study determined the influence of workplace and individual factors on filing of workers’ compensation claims by nursing home employees with back pain.

Methods

Surveys were conducted in 18 skilled nursing facilities in four U.S. states. Self-administered questionnaires obtained information on demographic characteristics, working environment, and health behaviors/status. Employees who reported low back pain at least once in four questionnaire surveys were included. WC claims from the same facilities were obtained from the employer’s workers compensation insurer and matched by employee name. The dichotomous dependent variable was filing of back-related worker’s compensation claim. Association with predictors of interest, including pain severity, physical job demand, job strain, social support, schedule control, and safety climate, was assessed using multivariate regression modeling. Individual characteristics were tested as potential confounders.

Results

Pain severity level was significantly associated with filing low-back related claims (odds ratio (OR) = 1.49, 95% CI = 1.18 – 1.87). Higher physical demands at work (OR = 1.07, 95% CI = 1.01 – 1.14) also increased the likelihood of claim filing. Higher job strain (OR = 0.83, 95% CI = 0.73 – 0.94), social support at work (OR = 0.90, 95% CI = 0.82 – 0.99), and education (OR = 0.79, 95% CI = 0.71 – 0.89) decreased the likelihood of claim filing.

Conclusions

The results suggest that the WC system captured the most severe occupational injuries. Workplace factors had additional influence on workers’ decision to file claims, after adjusting for low back pain severity. Education was correlated with worker’s socioeconomic status; its influence on claim filing is difficult to interpret because of the possible mixed effects of working conditions, self-efficacy, and content knowledge.

Results of a pilot intervention to improve health and safety for health care workers

OBJECTIVE

To test the feasibility of a multicomponent pilot intervention to improve worker safety and wellness in two Boston hospitals.

METHODS

A 3-month intervention was conducted on seven hospital units. Pre- (374 workers) and postsurveys (303 workers) assessed changes in safety/ergonomic behaviors and practices, and social support. Wellness outcomes included self-reported pain/aching in specific body areas (musculoskeletal disorders or MSDs) and physical activity (PA).

RESULTS

Pain was reported frequently (81%), and PA averaged 4 hours per week. There was a postintervention increase in safe patient handling (P < 0.0001), safety practices (P = 0.0004), ergonomics (P = 0.009), and supervisor support (P = 0.01), but no changes in MSDs or PA.

CONCLUSIONS

Safe patient handling, ergonomics, and safety practices are good targets for worker safety and wellness interventions; longer intervention periods may reduce the risk of MSDs.

Effect of systematic ergonomic hazard identification and control implementation on musculoskeletal disorder and injury risk

OBJECTIVES

This study aimed to examine the effect of an ergonomic hazard control (HC) initiative, undertaken as part of a company ergonomics standard, on worker injury risk.

METHODS

Using the company's ergonomic hazards database to identify jobs with and without ergonomic HC implementation and linking to individual job and injury histories, injury risk among person-jobs with HC implementation (the HC group) was compared to those without HC (NoHC group) using random coefficient models. Further analysis of the HC group was conducted to determine the effect of additional ergonomic hazards controlled on injury risk.

RESULTS

Among 123 jobs at 17 plant locations, 347 ergonomic hazards were quantitatively identified during the study period. HC were implemented for 204 quantified ergonomic hazards in 84 jobs, impacting 10 385 persons (12 967 person-jobs). No HC were implemented for quantified ergonomic hazards in the remaining 39 jobs affecting 4155 persons (5046 person-jobs). Adjusting for age, sex, plant origin, and year to control for any temporal trend in injury risk, the relative risk (RR) for musculoskeletal disorder (MSD) was 0.85 and the RR for any injury or MSD was 0.92 in the HC compared to NoHC group. Among the HC group, each ergonomic hazard controlled was associated with risk reduction for MSD and acute injury outcomes (RR 0.93).

CONCLUSION

Systematic ergonomic HC through participatory ergonomics, as part of a mandatory company ergonomics standard, is associated with MSD and injury risk reduction among workers in jobs with HC implemented.

Psychosocial stress and multi-site musculoskeletal pain: a cross-sectional survey of patient care workers

The aim of this study was to assess the relationship between psychosocial factors at work and multi-site musculoskeletal pain among patient care workers. In a survey of 1,572 workers from two hospitals, occupational psychosocial factors and health outcomes of workers with single and multi-site pain were evaluated using items from the Job Content Questionnaire that was designed to measure psychological demands, decision latitude, and social support. An adapted Nordic Questionnaire provided data on the musculoskeletal pain outcome. Covariates included body mass index, age, gender, and occupation. The analyses revealed statistically significant associations between psychosocial demands and multi-site musculoskeletal pain among patient care associates, nurses, and administrative personnel, both men and women. Supervisor support played a significant role for nurses and women. These results remained statistically significant after adjusting for covariates. These results highlight the associations between workplace psychosocial strain and multi-site musculoskeletal pain, setting the stage for future longitudinal explorations.

Association between work-family conflict and musculoskeletal pain among hospital patient care workers

BACKGROUND

A growing body of evidence suggests that work-family conflict is an important risk factor for workers' health and well-being. The goal of this study is to examine association between work-family conflict and musculoskeletal pain among hospital patient care workers.

METHODS

We analyzed a cross-sectional survey of 1,119 hospital patient care workers in 105 units in two urban, academic hospitals. Work-family conflict was measured by 5-item Work-Family Conflict Scale questionnaire. Multilevel logistic regression was applied to examine associations between work-family conflict and self-reported musculoskeletal pain in the past 3 months, adjusting for covariates including work-related psychosocial factors and physical work factors.

RESULTS

In fully adjusted models, high work-family conflict was strongly associated with neck or shoulder pain (OR: 2.34, 95% CI: 1.64-3.34), arm pain (OR: 2.79, 95% CI: 1.64-4.75), lower extremity pain (OR: 2.20, 95% CI: 1.54-3.15) and any musculoskeletal pain (OR: 2.45, 95% CI: 1.56-3.85), and a number of body areas in pain (OR: 2.47, 95% CI: 1.82-3.36) in the past 3 months. The association with low back pain was attenuated and became non-significant after adjusting for covariates.

CONCLUSIONS

Given the consistent associations between work-family conflict and self-reported musculoskeletal pains, the results suggest that work-family conflict could be an important domain for health promotion and workplace policy development among hospital patient care workers.

Relationship of sleep deficiency to perceived pain and functional limitations in hospital patient care workers

OBJECTIVE

Health care workers are at high risk of developing musculoskeletal symptoms and pain. This study tested the hypothesis that sleep deficiency is associated with pain, functional limitations, and physical limitations that interfere with work.

METHODS

Hospital patient care workers completed a survey (79% response rate) including measures of health, sociodemographic, and workplace factors. Associations of sleep deficiency with pain, work interference due to this pain, and functional limitations were determined.

RESULTS

Of 1572 respondents (90% women; mean age, 41 years), 57% reported sleep deficiency, 73% pain in last 3 months, 33% work interference, and 18% functional limitation. Sleep deficiency was associated with higher rates of pain, work interference, and functional limitation controlling for socioeconomic, individual, and workplace characteristics.

CONCLUSIONS

Sleep deficiency is significantly associated with pain, functional limitation, and workplace interference, suggesting modifiable outcomes for workplace health and safety interventions.
