Emotional Exhaustion in Healthcare Workers: Moving Beyond Coping Skills to Improve Organizational Conditions

OBJECTIVE

Emotional exhaustion (EE)-the first stage of burnout-is related to preventable work environment exposures. We examined the understudied impact of organizational support for safety (OSS) and safety hazards (SH) on EE in a mixed licensed and unlicensed population of healthcare workers (HCWs).

METHODS

A work environment exposures survey was conducted in five US public healthcare facilities in 2018-2019. A total of 1059 questionnaires were collected from a predominantly female population of mixed HCWs.

RESULTS

Mean EE scores were higher among women, direct care workers, and younger subjects. In linear regression models, EE was positively associated with SH, emotional labor, psychological demands, physical demands, job strain, assault, and negative acts, while OSS was negatively associated. Safety hazard s both mediated and moderated the relationship between OSS and EE.

CONCLUSIONS

When perception of SH is high, OSS has less impact on reducing EE, suggesting a need to effectively put safety policies to practice for improving EE in HCWS.

Participatory ergonomics: What works for whom and why? A realist review

Participatory workplace interventions to improve workforce musculoskeletal health are infrequently analysed regarding why they work, for whom or under what circumstances. This review sought to identify intervention strategies which achieved genuine worker participation. In total, 3388 articles on participatory ergonomic (PE) interventions were screened; 23 were suitable to analyse within a realist framework identifying contexts, mechanisms of change, and outcomes. The interventions which succeeded in achieving worker participation were characterised by one or more of these contexts: workers' needs as a core starting point; a positive implementation climate; clear distribution of roles and responsibilities; allocation of sufficient resources; and managerial commitment to and involvement in occupational safety and health. Interventions that were organised and delivered in this way generated relevance, meaning, confidence, ownership and trust for the workers in an interrelated and multi-directional manner. With such information, PE interventions may be carried out more effectively and sustainably in the future.Practitioner summary: This review focuses on the question: which mechanisms support genuine worker participation, in what context and with which necessary resources, to reduce musculoskeletal disorders. Results emphasise the importance of starting with workers' needs, making the implementation climate egalitarian, clarifying the roles and responsibilities of all involved, and providing sufficient resources.Abbreviations: PE: participatory ergonomic(s); WMSD: Work-related musculoskeletal disorders; EU: European Union; MSD: Muskuloskeletal disorders; OSH: Occupational health and safety; C: context; M: mechanism; O: outcome; CMOCs: CMO configurations; NPT: Normalization process theory; OECD: The Organisation for Economic Co-operation and Development: EU-OSHA: European Occupational Safety and Health Agency.

Work-Family Conflict and Depression Among Healthcare Workers: The Role of Sleep and Decision Latitude

BACKGROUND

Healthcare workers report a higher incidence of depression than the general population. Work-family conflict is a risk factor, but the mechanisms explaining its association with depression are not well understood. This study examines the potential mediating and moderating role of sleep and decision latitude in translating work-family conflict into depression.

METHODS

In 2018, a cross-sectional survey was collected from healthcare workers (n = 1,059) in five public sector facilities in the northeast United States. The survey included questions on participants' work-family conflict, depression, sleep duration and disturbances, decision latitude, and other work environments and socio-demographic characteristics. Multivariable linear and Poisson regression modeling were used to examine associations among variables.

FINDINGS

There was a significant association between work-family conflict and depression (β = 2.70, p < .001). Sleep disturbances, although not short sleep duration, partially mediated this association. The association between work family-conflict and depression was stronger among workers with low decision latitude.

CONCLUSIONS

Depression was prevalent among healthcare workers and was associated with work-family conflict. Sleep disturbances served as a significant mediator, while decision latitude modified the strength of the association.

APPLICATION TO PRACTICE

Evidence-based interventions seeking to alleviate the effect of work-family conflict and improve healthcare workers' mental health should consider promoting employee sleep quality and improving employees' decision-making on the job.

Adherence to Mediterranean Diet and Depressive Symptomatology Among Boston Area Puerto Ricans

BACKGROUND

Higher Mediterranean diet (MeD) adherence has been linked with lower depressive symptomatology, but research examining this association is limited, especially among Latinos, including mainland U.S. Puerto Ricans. Hence, we examined cross-sectional and longitudinal associations between MeD adherence and self-reported depressive symptomatology in Boston area Puerto Rican adults.

METHODS

The Center for Epidemiologic Studies Depression Scale (CES-D) was used to evaluate depressive symptoms. Adherence to MeD was assessed at all 3 visits. We used multivariable linear regression for baseline cross-sectional analysis, and linear mixed effects modeling over 3 waves of follow-up for longitudinal analysis. We also assessed whether baseline MeD adherence affected 5y CES-D trajectory. We conducted sensitivity analyses among participants without diabetes, and among participants with complete MeD and CES-D measures at all visits.

RESULTS

MeD adherence was significantly associated with CES-D score at baseline (β = -2.0, 95% confidence interval [CI] -4.0, -0.04 for highest vs lowest tertile, p trend = .04) and across 3 waves (β = -1.9, 95% CI = -3.0, -0.8 for highest vs lowest tertile, p trend = .0005). Results were similar in analyses restricted to participants without diabetes, as well as among participants with complete CES-D and MeD scores at all visits.

CONCLUSIONS

While CES-D score was consistently lower in those with higher MeD adherence over 5 years of follow up, no relationship between baseline MeD adherence and 5y CES-D trajectory was observed.

Health Care Organization Policies for Employee Safety and COVID-19 Pandemic Response: A Mixed-Methods Study

OBJECTIVE

The coronavirus (COVID-19) pandemic impacted the well-being of health care workers. We examined the association between prepandemic perceptions of perceived organizational support for safety (using NOSACQ-50), safety hazards and the pandemic's impact on individual workers and institutions.

METHODS

Questionnaires from health care staff of five public health care facilities were collected in 2018 ( n = 1059) and 2021 ( n = 1553). In 2021, 17 workers were interviewed from the same facilities.

RESULTS

Interviewees reported that their organizations struggled to communicate due to changing guidelines, inadequate personal protective equipment, training, and infection control, early in the pandemic. Questionnaire reports of decreased staffing and increased workload during the pandemic were associated with lower baseline NOSACQ scores.

CONCLUSION

Survey findings predicted some variation in organizational response to the pandemic. Better organizational policies for employee safety and pandemic planning could improve health care institutions' preparedness.

Risk factors for surgically treated cervical spondylosis in male construction workers: a 20-year prospective study

BACKGROUND CONTEXT

Degenerative changes due to cervical spondylosis (CS) can detrimentally affect work ability and quality of life yet understanding of how physical exposure affects disease progression is limited.

PURPOSE

To assess the associations between occupational physical exposures and occurrence of surgically treated cervical spondylosis (ST-CS) and early exit from the labor market via disability pension.

STUDY DESIGN/SETTING

Prospective register study with 20 years follow-up period.

PATIENT SAMPLE

Swedish construction workers participating in a national health surveillance project conducted between 1971 and 1993.

OUTCOME MEASURES

Surgically treated cervical spondylosis (ST-CS) and early labor market exit at a minimum rate of 25% time on disability pension.

METHODS

Associations between occupational physical exposures (job exposure matrix) and subsequent ST-CS (National Hospital in-patient register) and early labor market exit via disability pension (Swedish Social Insurance Agency register) were assessed in a cohort of male construction workers (n=237,699).

RESULTS

A total of 1381 ST-CS cases were present and a 20 years incidence rate of 35.1 cases per 100,000 person years (95% confidence interval (CI) 33.2-36.9). Increased relative risk (RR) for ST-CS was found for workers exposed to non-neutral (RR 1.40, 95% CI 1.15-1.69), and awkward neck postures (1.52, 1.19-1.95), working with the hands above shoulder height (1.30, 1.06-1.60), and high upper extremity loading (1.35, 1.15-1.59). Increased risk was also present for workers who reported frequent neck (3.06, 2.18-4.30) and upper back (3.84, 2.57-5.73) pain in the 12 months prior to survey. Among workers with elevated arm exposure, higher risk was seen in those who also had more frequent neck pain. ST-CS cases took early retirement more often (41.3%) and at a younger age (53 years) than the total study cohort (14.8% and 56 years of age, respectively).

CONCLUSIONS

Occupational exposure to non-neutral neck postures, work with hands above shoulders and high loads born through the upper extremities increased the risk for ST-CS and early retirement due to disability. Decreasing postural and load exposure is salient for primary, secondary, and tertiary prevention of CS. Neck pain was shown to be a prognostic factor for ST-CS, which stresses the importance of acting early and taking preventative action to reduce workplace exposure, and the need for systematic medical check-ups within primary or occupational care to mitigate disease progression and early labour market exit due to disability.

Response to NIOSH Request for Information on Interventions to Prevent Work-Related Stress and Support Health Worker Mental Health

The root causes of health care worker strain and depression include excessive job demands, extended work schedules, little decision-making opportunity, assault, bullying, and fear of injury. Potential links between working conditions and opioid overuse have also been discussed, beginning with psychological job strain or with physical pain leading to medication use. Promising solutions have been identified and many would be cost-effective, as enhanced working conditions could improve workers' mental health, job satisfaction, retention, and patient outcomes. Considering the number of health care workers leaving work during the global COVID-19 pandemic, it is urgent to address preventable root causes. In 2021, the US Congress called for educating health workers and first responders on the primary prevention of mental health conditions and substance use disorders. The CDC issued a Request for Information; this submission summarized research from CPH-NEW, a NIOSH Center of Excellence in Total Worker Health®, supplemented by a selective literature review.

Using Participatory Ergonomics to Improve Health and Safety in Commercial Lobstering in the United States: 2 Case Studies

The lobster-harvesting industry has a high occupational injury incidence compared to land-based industries. Participatory ergonomics methods were used to partner with lobstermen to develop and implement ergonomic improvements. The model included training in ergonomics principles, a forum for ergonomics discussions, and a sequence of meetings planned to focus on problem identification, intervention, evaluation, and dissemination of findings. One crew initiated 3 specific actions: the introduction of a conveyor belt to assist material handling at a local lobstering pier, the installation of a star block at the space for hauling traps onto the boat, and the initiation of a design process for improved mechanical assistance for hauling traps onto the boat. The other crew took action to reduce force and postural exposures by creating a short video intended to disseminate ergonomic ideas to other lobstermen. The influence of important cultural norms was observed for future research and development in the community.

Use of a Mobile App for the Process Evaluation of an Intervention in Health Care: Development and Usability Study

BACKGROUND

Process evaluation measures the context in which an outcome was or was not achieved through the ongoing monitoring of operations. Mobile apps are a potentially less burdensome tool for collecting these metrics in real time from participants. Research-driven apps are not always developed while paying attention to their usability for target users. Usability testing uncovers gaps in researchers', developers', and users' mental models of what an efficient, effective, and satisfying product looks like and facilitates design improvement. Models may vary by user demographics.

OBJECTIVE

This study describes the development of a mobile app for collecting process evaluation metrics in an intervention study with health care workers that uses feedback at multiple stages to refine the app design, quantify usage based on workers' overall adoption of the app and the app's specific function, and compare the demographic and job characteristics of end users.

METHODS

An app was developed to evaluate the Center for Promotion of Health in the New England Workplace Healthy Workplace Participatory Program, which trains teams to develop solutions for workforce health obstacles. Labor-management health and safety committee members, program champions, and managers were invited to use the app. An accompanying website was available for team facilitators. The app's 4 functions were meeting creation, postmeeting surveys, project time logs, and chat messages. Google Analytics recorded screen time. Two stages of pilot tests assessed functionality and usability across different device software, hardware, and platforms. In stage 1, student testers assessed the first functional prototype by performing task scenarios expected from end users. Feedback was used to fix issues and inform further development. In stage 2, the app was offered to all study participants; volunteers completed task scenarios and provided feedback at deployment. End user data for 18 months after deployment were summarized and compared by user characteristics.

RESULTS

In stage 1, functionality problems were documented and fixed. The System Usability Scale scores from 7 student testers corresponded to good usability (mobile app=72.9; website=72.5), whereas 15 end users rated usability as ok (mobile app=64.7; website=62.5). Predominant usability themes from student testers were flexibility and efficiency and visibility of system status; end users prioritized flexibility andefficiency and recognition rather than recall. Both student testers and end users suggested useful features that would have resulted in the large-scale restructuring of the back end; these were considered for their benefits versus cost. In stage 2, the median total use time over 18 months was 10.9 minutes (IQR 23.8) and 14.5 visits (IQR 12.5). There were no observable patterns in use by demographic characteristics.

CONCLUSIONS

Occupational health researchers developing a mobile app should budget for early and iterative testing to find and fix problems or usability issues, which can increase eventual product use and prevent potential gaps in data.

Evaluation of the HearWell Pilot Program: A Participatory Total Worker Health® Approach to Hearing Conservation

Our objective was to pilot test HearWell, an intervention created to preserve hearing among highway maintainers, by using a participatory Total Worker Health^® (TWH) approach to designing, implementing and evaluating interventions. Regional maintenance garages were randomized to control (n = 6); HearWell (n = 4) or HearWell Design Team (n = 2) arms. Maintainer representatives from the HearWell Design Team garages identified barriers to hearing health and collaborated to design interventions including a safety leadership training for managers, a noise hazard management scheme to identify noise levels and indicate the hearing protection device (HPD) needed, and a comprehensive HearWell training video and protocol. These worker-designed interventions, after manager input, were delivered to the HearWell Design Team and the HearWell garages. Control garages received standard industry hearing conservation training. Periodic surveys of workers in all 12 garages collected information on the frequency of HPD use and a new hearing climate measure to evaluate changes in behaviors and attitudes over the study period and following interventions. An intention-to-treat approach was utilized; differences and trends in group HPD use and hearing climate were analyzed using a mixed-effects model to account for repeated measures from individual participants. The HearWell Design Team maintainers reported the highest frequency of HPD use. Hearing climate improved in each group 6 months following intervention implementation, with the largest increase and highest value for the HearWell Design Team workers. The HearWell pilot intervention showed promising results in improving HPD use through a participatory TWH approach to hearing conservation. Furthermore, results suggest that employee participation in hearing conservation programs may be necessary for maximal effectiveness.

1150Changes in job security and mental health over 14 waves of a working population survey

Background & Methods

We examined whether job security improvements were associated with improvements in mental health in a large Australian nationally representative panel study. We used both within-person fixed effects (FE) and random effects (RE) regression to analyse data from 14 annual waves covering calendar years 2002—2015 (19,169 persons, 106,942 observations). Mental Health Inventory-5 scores were modeled in relation to self-reported job security (categorical, quintiles), adjusting for age, year, education, and job change in the past year.

Results

Both FE and RE models showed stepwise improvements in MHI-5 scores with improving job security, with stronger exposure-outcome relationships in the RE models and for men compared to women. The RE coefficients for improvements in job security in males were 2.06 [1.67, 2.46] for one quintile, steadily increasing for two- (3.94 [3.54, 4.34]), three- (5.82 [5.40, 6.24]), and four- (7.18 [6.71, 7.64]) quintile improvements. The FE model for males produced slightly smaller coefficients, reaching a maximum of 5.55 [5.06, 6.05]. Supplementary analyses investigated whether six waves of cumulative exposure to job security (higher value = higher security) predicted MHI-5 score (improvement in mental health) in the seventh wave: results showed a strong dose-response (beta cumulative security was 0.60 [0.53-0.68]), with the difference between lowest and highest values of exposure corresponding to a 14-point increase in MHI-5 score.

Conclusions

These analyses, with improved causal inference over previous observational research, showed that improving job security is strongly associated with decreasing depression and anxiety symptoms.

Key messages

Policy and practice intervention to improve job security could benefit population mental health.

The Contribution of Occupation-Specific Factors to the Deaths of Despair, Massachusetts, 2005-2015

OBJECTIVES

In the USA, deaths from poisonings (especially opioids), suicides, and alcoholic liver disease, collectively referred to as 'deaths of despair', have been increasing rapidly over the past two decades. The risk of deaths from these causes is known to be higher among certain occupations. It may be that specific exposures and experiences of workers in these occupations explain these differences in risk. This study sought to determine whether differences in the risk of deaths of despair were associated with rate of occupational injuries and illnesses, job insecurity, and temporal changes in employment in non-standard work arrangements.

METHODS

Usual occupation information was collected from death certificates of Massachusetts residents aged 16-64 with relevant causes of death between 2005 and 2015. These data were combined with occupation-level data about occupational injuries and illnesses, job insecurity, and non-standard work arrangements. We calculated occupation-specific mortality rates for deaths of despair, categorized by occupational injury and illnesses rates and job insecurity. We calculated trends in mortality according to changes in non-standard work arrangements.

RESULTS

Workers in occupations with higher injury and illnesses rates and more job insecurity had higher rates of deaths of despair, especially opioid-related deaths. Rates of deaths of despair increased most rapidly for occupations with increasing prevalence of workers employed in non-standard work arrangements.

CONCLUSIONS

The findings suggest occupational factors that may contribute to the risk of deaths of despair. Future studies should examine these factors with individual-level data. In the meantime, efforts should be made to address these factors, which also represent known or suspected hazards for other adverse health outcomes.

Workplace Sexual Harassment and Vulnerabilities among Low-Wage Hispanic Women

Workplace sexual harassment is particularly widespread in industries with many low-wage jobs where Hispanic women are likely to work. This qualitative study examines the experiences of Hispanic women in low-income jobs to identify workplace sexual harassment situations, support seeking actions, barriers to report, and forms of retaliation. A qualitative research design with one-on-one structured interviews provided an in-depth understanding of the experiences of Hispanic women in low-wage jobs regarding workplace sexual harassment situations and potential contributing factors. Second, a conceptual framework is proposed to integrate the reported organizational factors and social vulnerabilities that interact, eroding the individual's ability to cope effectively with workplace sexual harassment. These include organizational resources for preventing and reporting, community and family resources for support, and health effects attributed to sexual harassment. Workplace sexual harassment was described by participants as escalating over time from dating invitations, sex-related comments, unwanted physical contact to explicit sexual propositions. Temporary workers reported being very often subject to explicit quid pro quo propositions. While these patterns might not differ from those reported by other groups, work organization factors overlap with individual and social characteristics of Hispanic women in low-income jobs revealing a complicated picture that requires a systems approach to achieve meaningful change for this vulnerable population.

A mixed-method approach to tailor the implementation of a participatory Total Worker Health® program

Purpose –

Total Worker Health^® (TWH) programs, which represent a holistic approach for advancing worker safety, health and well-being, require an employer to adapt programmatic coordination and employee involvement in program design and delivery. Organizational readiness for such measures requires competencies in leadership, communication, subject expertise and worker participation. In the absence of documented methods for TWH readiness assessment, the authors developed a process to prospectively identify implementation facilitators and barriers that may be used to strengthen organizational competencies and optimize the organizational "fit" in advance.

Design/methodology/approach –

The mixed-method baseline assessment instruments comprised an online organizational readiness survey and a key leader interview; these were administered with key organizational and labor leaders in five US healthcare facilities. Findings about organizational resources, skills available and potential implementation barriers were summarized in a stakeholder feedback report and used to strengthen readiness and tailor implementation to the organizational context.

Findings –

The research team was able to leverage organizational strengths such as leaders' commitment and willingness to address nontraditional safety topics to establish new worker-led design teams. Information about program barriers (staff time and communication) enabled the research team to respond with proactive tailoring strategies such as training on participant roles, extending team recruitment time and providing program communication tools and coaching.

Originality/value –

A new method has been developed for prospective organizational readiness assessment to implement a participatory TWH program. The authors illustrate its ability to identify relevant organizational features to guide institutional preparation and tailor program implementation.

Emotional Labor and Depressive Symptoms Among Healthcare Workers: The Role of Sleep

BACKGROUND

Depression is the second leading cause of disability worldwide. Health care workers report a higher prevalence of depressive symptoms than the general population. Emotional labor has contributed to poor health and work outcomes. However, the mechanism for the potential association between emotional labor and depressive symptoms has not been well studied. This study examines the relationship between emotional labor and depressive symptoms and whether sleep plays a role in explaining this relationship.

METHODS

In 2018, health care workers (n = 1,060) from five public sector facilities in the northeast United States participated in this cross-sectional survey. The survey included questions on participants' surface-acting emotional labor (masking one's feelings at work), depressive symptoms, sleep duration and disturbances, and socio-demographic characteristics. Multivariable linear and Poisson regression modeling were used to examine associations among variables.

FINDINGS

There was a significant association between emotional labor and depressive symptoms (β = 0.82, p < .001). Sleep disturbances, but not short sleep duration, partially mediated this association. Neither sleep variable moderated this association.

CONCLUSIONS/APPLICATION TO PRACTICE

Depressive symptoms were prevalent among health care workers and were associated with emotional masking. Sleep disturbances play an important intermediate role in translating emotional labor to depressive symptoms in these workers. Effective workplace programs are needed to reduce health care workers' emotional labor to improve their mental health. Sleep promotion should also be emphasized to mitigate the negative effect of emotional labor and promote mental wellbeing.

Feasibility of Virtual Focus Groups in Program Impact Evaluation

Focus groups are often used for qualitative investigations. We adapted a published focus group method for evaluating impact of an organizational intervention for virtual delivery using video conferencing. The method entailed convening small groups of three to five participants for a 2-hour facilitated workshop. We delivered the virtual workshops, adding qualitative evaluation with researchers and participants, to assess the effectiveness of the protocol. We address the questions of how to structure the data collection procedures; whether virtual delivery permits cross participant interactions about a studied intervention; and how easy and comfortable the experience was for participants. Participants were university faculty members who were the focus of an institutional diversity program. The results indicated that the virtually delivered focus group workshop could be successfully implemented with strong fidelity to the original protocol to achieve the workshop goals. The workshops generated rich data about the impacts of the institutional program as well as other events and conditions in the working environment that were relevant to consider along with the observed program outcomes. A well-planned virtual focus group protocol is a valuable tool to engage intervention stakeholders for research and evaluation from a distance. Video conferencing is especially useful during the current COVID-19 pandemic, but also whenever geography separates researchers and evaluators from program stakeholders. Careful planning of privacy measures for a secure online environment and procedures for structured facilitation of group dialogue are critical for success, as in any focus group. This article addresses a gap in the literature on feasibility and methodology for using video conference technology to conduct qualitative data collection with groups.

750 Sleep disturbances mediates the association between emotional labor and depressive symptoms among healthcare workers

Introduction

Depression is the second leading cause of disability worldwide. Healthcare workers report a higher prevalence of depressive symptoms than the general population. Emotional labor has contributed to poor health and work outcomes. However, the mechanism for the potential association between emotional labor and depressive symptoms has not been well studied.

Methods

In 2018, healthcare workers (n=1,060) from five public sector facilities in the northeast U.S. participated in this cross-sectional survey. The survey included questions on participants’ surface-acting emotional labor (masking one’s feelings at work), depressive symptoms, sleep duration and disturbances, and socio-demographics.

Results

Nearly a quarter (21.7%) of the participants reported depressive symptoms, over a half (53.6%) reported short sleep duration (≤6 hours per day), and nearly one third (32.2%) reported sleep disturbances. There was a significant association between emotional labor and depressive symptoms (β=0.82, p&lt;0.001) among these workers. Sleep disturbances, not short sleep duration, partially mediated this association by 17%. Both sleep disturbances and short sleep duration did not modify this association.

Conclusion

Depressive symptoms were prevalent among healthcare workers and were associated with emotional masking. Sleep disturbances play an important intermediate role in translating emotional labor to depressive symptoms in these workers. Effective workplace programs are needed to reduce healthcare workers’ emotional labor in order to improve their mental health. Sleep promotion should be emphasized to mitigate the negative effect of emotional labor and promote healthcare workers’ mental wellbeing.

Changes in Job Security and Mental Health: An Analysis of 14 Annual Waves of an Australian Working-Population Panel Survey

We examined whether job security improvements were associated with improvements in mental health in a large, nationally representative panel study in Australia. We used both within-person fixed effects (FE) and random effects (RE) regression to analyze data from 14 annual waves covering the calendar period of 2002-2015 (19,169 persons; 106,942 observations). Mental Health Inventory-5 scores were modeled in relation to self-reported job security (categorical, quintiles), adjusting for age, year, education, and job change in the past year. Both FE and RE models showed stepwise improvements in Mental Health Inventory-5 scores with improving job security, with stronger exposure-outcome relationships in the RE models and for men compared with women. The RE coefficients for improvements in job security in men were 2.06 (95% confidence interval (CI): 1.67, 2.46) for 1 quintile, steadily increasing for 2- (3.94 (95% CI: 3.54, 4.34)), 3- (5.82 (95% CI: 5.40, 6.24)), and 4-quintile (7.18 (95% CI: 6.71, 7.64)) improvements. The FE model for men produced slightly smaller coefficients, reaching a maximum of 5.55 (95% CI: 5.06, 6.05). This analysis, with improved causal inference over previous observational research, showed that improving job security is strongly associated with decreasing depression and anxiety symptoms. Policy and practice intervention to improve job security could benefit population mental health.

Promoting Opioid Awareness Through a Union-Based Peer Training Model

Work factors, including physical job demands, appear to be risk factors for opioid overdoses. We collaborated with unions representing workers in high-risk occupations and offered resources to develop tailored educational interventions for their members. An ironworkers' local, a statewide nurses' union, and a Teamsters local union participated, at levels higher than we had anticipated. The three unions trained 285 workers, including apprentices, stewards, and those nearing retirement. Short surveys assessed pre- and post-training knowledge, attitudes, confidence in helping others, and related domains. Seventy percent of respondents reported heavy or very heavy physical demands at work, and one-half had experienced work-related pain. After training, participants reported more knowledge about opioids, less concern about stigma related to help-seeking, and more ability to provide help to a co-worker struggling with opioids. Peers with recovery experience provided a unique contribution to training. Tailored job-specific and peer-delivered educational interventions may be able to reduce the potential impact of opioids on working people.

Serum Vitamin D and Depressive Symptomatology among Boston-Area Puerto Ricans

BACKGROUND

Low vitamin D status, assessed using serum 25-hydroxyvitamin D [25(OH)D] concentration, has been associated with depression, but research among minority populations, such as Puerto Ricans is limited. We examined the association between serum 25(OH)D and self-reported depressive symptomatology across 3 waves of follow-up in a cohort of Puerto Rican adults residing in Massachusetts.

OBJECTIVES

We evaluated the cross-sectional and longitudinal associations between serum 25(OH)D and self-reported depressive symptoms in the Boston Puerto Rican Health Study (BPRHS) cohort.

METHODS

Participants of the BPRHS were evaluated for depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CES-D). Serum 25(OH)D was measured at baseline (n = 1434), year 2 (n = 1218), and year 5 (n = 914). We categorized serum 25(OH)D concentration as sufficient (≥20 ng/mL), insufficient (12 to <20 ng/mL), and deficient (<12 ng/mL). Multivariable linear regression was used for cross-sectional analyses at baseline, and repeated measures mixed effects modeling was used over 3 waves of follow-up for longitudinal analyses. We conducted sensitivity analyses in vitamin D supplement nonusers and participants with complete data on baseline serum 25(OH)D and CES-D at all 3 visits.

RESULTS

Serum 25(OH)D concentration was not associated with CES-D score in cross-sectional analysis [β = -0.85; 95% CI: -2.80, 1.10 for deficient compared with sufficient 25(OH)D; P-trend = 0.59] or in longitudinal analyses over 5 y [β = -0.41; 95% CI: -1.95, 1.13 for deficient compared with sufficient 25(OH)D; P-trend = 0.93]. Results were similar in sensitivity analyses restricted to vitamin D supplement nonusers (n = 1371) and in analyses conducted in participants with complete measures of baseline serum 25(OH)D and CES-D score at all 3 visits (n = 887) [β = -0.12; 95% CI: -1.98, 1.74 for deficient compared with sufficient 25(OH)D; P-trend = 0.93].

CONCLUSIONS

We did not observe a significant association between serum 25(OH)D and depressive symptomatology in the BPRHS cohort.

A Corporate Wellness Program and Nursing Home Employees' Health

Background: Many employed Americans suffer from chronic conditions like obesity, diabetes, and cardiovascular diseases. Worksite wellness programs provide opportunities to introduce health promotion strategies. While there is evidence of the effectiveness of workplace health promotion, this is tempered by concern that benefits may be less available to low-wage workers with inflexible working conditions. Objective: The aim was to evaluate a workplace health promotion (WHP) in the long-term care sector (skilled nursing facilities). Methods: Nursing home employees from 18 facilities within a single company were surveyed by a standardized, self-administered questionnaire. A company-sponsored WHP program was offered to the facilities, which were free to take it up or not. We categorized the facilities by level of program adoption. Cross-sectional associations were estimated between program category and prevalence of individual-level worker health indicators, adjusting for center-level working conditions. Results: A total of 1,589 workers in 5 job categories completed the survey. Average levels of psychological demands and social support at work were relatively high. Supervisor support stood out as higher in centers with well-developed WHP programs, compared to centers with no programs. There were no differences among program levels for most health outcomes. Workers in centers with well-developed programs had slightly lower average body mass index and (unexpectedly) slightly lower prevalence of non-smoking and regular aerobic exercise. Conclusions: Only small health benefits were observed from well-developed programs and working conditions did not appear to confound the negative results. This low-intensity, low-resourced workplace health promotion program may have benefited a few individuals but seems to have had only modest influence on average levels of the measured health indicators. Many nursing home employees experience obstacles to health behaviors; approaches that provide more environmental and economic supports for healthy behaviors, such as Total Worker Health®, may yield larger health benefits.

Surface-acting emotional labor predicts depressive symptoms among health care workers over a 2-year prospective study

OBJECTIVE

Surface-acting emotional labor (SaEL) is the requirement to hide or suppress felt emotions to achieve acceptable job performance. It is a common feature of jobs featuring interactions with the public, such as customers or patients. Resulting emotional inauthenticity is associated with psychological strain, but there have been few prospective studies of mental health outcomes.

METHODS

A self-administered questionnaire was distributed in 24 skilled nursing facilities at baseline and 23 facilities 2 years later. Permanent full-time and part-time employees in all jobs were eligible to participate. Respondents in these analyses provided survey information on the frequency of SaEL at baseline and depressive symptoms on both occasions. Those without depression at baseline were deemed at risk. Multivariable logistic regression modeling estimated adjusted odds ratios (aOR) for SaEL, other job features, and demographic characteristics.

RESULTS

A total of 939 eligible participants had no depression at baseline; 15% developed depressive symptoms. About two-thirds were direct care providers, including 38% nursing and medical assistants. Adjusted for potential confounders, workers with intermediate and high SaEL had a higher risk (aORs around 2). Symptom onset was also predicted by high work-family conflict, younger age and low decision latitude at work.

CONCLUSIONS

In this prospective study of long-term care workers, those who reported experiencing high SaEL at the time of the baseline survey were at higher risk of developing depressive symptoms 2 years later. Both exposure and outcome could have suffered some misclassification. Future studies should examine a broader range of strategies for coping with emotional labor demands.

Safety and Health through Integrated, Facilitated Teams (SHIFT): stepped-wedge protocol for prospective, mixed-methods evaluation of the Healthy Workplace Participatory Program

BACKGROUND

Healthcare facilities are notorious for occupational health and safety problems. Multi-level interventions are needed to address interacting exposures and their overlapping origins in work organization features. Worker participation in problem identification and resolution is essential. This study evaluates the CPH-NEW Healthy Workplace Participatory Program (HWPP), a Total Worker Health® protocol to develop effective employee teams for worker safety, health, and wellbeing.

METHODS

Six public sector, unionized healthcare facilities are enrolled, in three pairs, matched by agency. The unit of intervention is a workplace health and safety committee, adapted here to a joint labor-management "Design Team" (DT). The DT conducts root cause analyses, prioritizes problems, identifies feasible interventions in light of the constraints and needs of the specific setting, makes business-case presentations to facility leadership, and assists in evaluation. Following a stepped-wedge (cross-over) design, one site in each pair is randomly assigned to "immediate intervention" status, receiving the full coached intervention at baseline; in the "lagged intervention" site, coaching begins about half-way through the study. Program effectiveness and cost-effectiveness outcomes are assessed at both organizational (e.g., workers' compensation claim and absenteeism rates, perceived management support of safety) and individual levels (e.g., self-rated health, sleep quality, leisure-time exercise). Targeted pre-post analyses will also examine specific outcomes appropriate to the topics selected for intervention. Process evaluation outcomes include fidelity of the HWPP intervention, extent of individual DT member activity, expansion of committee scope to include employee well-being, program obstacles and opportunities in each setting, and sustainability (within the available time frame).

DISCUSSION

This study aims for a quantitative evaluation of the HWPP over a time period long enough to accomplish multiple intervention cycles in each facility. The design seeks to achieve comparable study engagement and data quality between groups. We will also assess whether the HWPP might be further improved to meet the needs of U.S. public sector healthcare institutions. Potential challenges include difficulty in pooling data across study sites if Design Teams select different intervention topics, and follow-up periods too short for change to be observed.

Work Environment Factors and Prevention of Opioid-Related Deaths

Opioid use disorder (OUD) and opioid overdose deaths (OODs) are prevalent among US workers, but work-related factors have not received adequate attention as either risk factors or opportunities for OOD prevention. Higher prevalence of OOD in those with heavy physical jobs, more precarious work, and limited health care benefits suggest work environment and organizational factors may predispose workers to the development of OUD.Organizational policies that reduce ergonomic risk factors, respond effectively to employee health and safety concerns, provide access to nonpharmacologic pain management, and encourage early substance use treatment are important opportunities to improve outcomes. Organizational barriers can limit disclosure of pain and help-seeking behavior, and opioid education is not effectively integrated with workplace safety training and health promotion programs.Policy development at the employer, government, and association levels could improve the workplace response to workers with OUD and reduce occupational risks that may be contributing factors.

Association between extremely long working hours and musculoskeletal symptoms: A nationwide survey of medical residents in South Korea

OBJECTIVES

It has been reported that South Korea ranked as one of the longest-working nations among OECD countries. This study sought to examine the association between long working hours and musculoskeletal pain among Korean medical residents.

METHODS

We analyzed a cross-sectional survey of 1,077 medical residents in South Korea. Working hours per week were categorized as follows: <60, 60-79, 80-99, and ≥100. Musculoskeletal pains (ie, upper limb, lower limb, and low back pain) over the past 3 months were categorized into three groups: no pain, pain without interfering with work, and pain interfering with work. Multinomial logistic regression was used to examine the association between long working hours and musculoskeletal pains after adjusting for covariates.

RESULTS

We found that the average working hours of medical resident was 85.6 hours per week in South Korea. Compared to the medical residents working <60 hours, those working ≥100 hours per week were more likely to have upper limb pain (PR: 1.77, 95% CI: 1.37, 2.30) interfering with work or low back pain (PR: 2.15, 95% CI: 1.51, 3.06) interfering with work, whereas no statistically significant association was observed in the analysis of lower limb pain.

CONCLUSIONS

This study suggests that extremely long working hours are associated with upper limb and low back pain interfering with their work among Korean medical residents.

0778 Workplace Yoga Program Features and Associations With Shift Work and Sleep Among Nursing Staff

Introduction

Nursing staff are at risk for impaired sleep due to irregular schedules, long work hours, and other occupational stress. Yoga has demonstrated beneficial effects on sleep in healthy adults and patients with chronic diseases. However, yoga interventions are generally offered as 60-75-minute sessions; this long duration might not be suitable as a workplace program for nursing staff. The objective of this study is to examine workplace yoga program features and associations with shift work and sleep among nursing staff.

Methods

Online Qualtrics surveys were distributed among nurses and nursing assistants at a community hospital in the northeast U.S. Hypothetical workplace yoga program features were assessed including general interest, duration, frequency, timing with respect to work shift, and interest in home practice. Sleep duration and disturbances were assessed.

Results

Among the 541 participants (94% female; age 43±13y), over a third reported sleep ≤6hrs/day (38%) and sleep disturbances (38%), and 79% reported interest in workplace yoga. Among those reporting interest, after work (61%), 30min/session (73%), 3 sessions/week (56%), and interests in home practice (64%) were yoga features endorsed by nursing staff. Night or ≥12hr shift was associated with less interest in workplace yoga. Evening or ≥12hr shift was associated with less interest in yoga after work, while day or night shift was associated with less interest in yoga before work. Mild sleep disturbances were associated with more interest while severe disturbances were associated with less interest in yoga after work. Nursing staff with sleep≤6hrs/day reported less interest in yoga before work, but more interest in home yoga practice.

Conclusion

Nursing staff reported a high prevalence of short and disturbed sleep and interest in workplace yoga. Workplace yoga programs need to be designed according to nursing staff’s interest while considering the effect of shift work and sleep problems reported by nursing staff.

1024 Associations Of Low Back Pain And Sleep Among Nursing Staff

Introduction

Nursing is one of the top occupations suffering musculoskeletal disorders, especially low back pain (LBP). Nursing staff also experience short and disturbed sleep. Although there is a known relationship between pain and sleep, the specific associations between different aspects of LBP (e.g., duration, frequency, intensity) and sleep have not been studied. The objective of this study is to examine different aspects of LBP and their cross-sectional associations with sleep among nursing staff.

Methods

Online Qualtrics surveys were distributed among nurses and nursing assistants at a community hospital in the northeast U.S. LBP was assessed in terms of duration, frequency, intensity, and intensity change from before to after the work shift. Sleep duration and disturbances were assessed with validated scales.

Results

Among the 541 participants (94% female; age 43±13y), more than a third reported short sleep duration (≤6hrs/day; 38%) or sleep disturbances (38%), and more than half (60%) reported LBP in the past 6 months. Among those with LBP, 82% had ongoing pain for at least 6 months; 44% had ongoing pain for at least half the days in the past 6 months; 39% had LBP intensity ≥4 out of 10; and 79% reported post-shift LBP intensity increased of at least 1 level. Short sleep duration was associated with ongoing LBP for at least half the days in the past 6 months, intensity ≥4, and post-shift LBP intensity increase. Sleep disturbances were associated with prevalent LBP and intensity ≥4.

Conclusion

Nursing staff reported a high prevalence of LBP as well as short and disturbed sleep. Overall, poor sleep was associated with higher LBP prevalence, frequency, intensity, and post-shift increase. Future longitudinal studies are needed to clarify the causal directions of these relationships. Workplace interventions should address the widespread problems of LBP and sleep deficiency of nursing staff.

Defining 'Integration' for Total Worker Health®: A New Proposal

The effects of work and the conditions of employment on health behaviors and intermediate health conditions have been demonstrated, to the extent that these relationships should be addressed in efforts to prevent chronic disease. However, conventional health promotion practice generally focuses on personal risk factors and individual behavior change. In an effort to find solutions to the myriad of health challenges faced by the American workforce, the U.S. National Institute for Occupational Safety and Health (NIOSH) established the Total Worker Health® (TWH) program. Originally organized around the paradigm of integrating traditional occupational safety and health protections with workplace health promotion, TWH has evolved to a broader emphasis on workplace programs for enhancing worker safety, health, and well-being. Among the research programs and approaches developed by investigators at NIOSH Centers of Excellence for TWH and elsewhere, definitions of 'integration' in workplace interventions vary widely. There is no consensus about which organizational or individual outcomes are the most salient, how much to emphasize organizational contexts of work, or which program elements are necessary in order to qualify as 'Total Worker Health'. Agreement about the dimensions of integration would facilitate comparison of programs and interventions which are self-defined as TWH, although diverse in content. The specific criteria needed to define integration should be unique to that concept-i.e. distinct from and additive to conventional criteria for predicting or evaluating the success of a workplace health program. We propose a set of four TWH-specific metrics for integrated interventions that address both program content and process: (i) coordination and interaction of workplace programs across domains; (ii) assessment of both work and non-work exposures; (iii) emphasis on interventions to make the workplace more health-promoting; and (iv) participatory engagement of workers in pivotal ways during intervention prioritization and planning to develop self-efficacy in addressing root causes, skill transfer, building program ownership, empowerment, and continuous improvement. Thus we find that integration requires organizational change, both to engage two managerial functions with different goals, legal responsibilities, and (often) internal incentives & resources, and also to orient the organization toward salutogenesis. Examples from research activity within the Center for the Promotion of Health in the New England Workplace illustrate how these criteria have been applied in practice.

A Participatory Action Research Approach to Mental Health Interventions among Corrections Officers: Standardizing Priorities and Maintaining Design Autonomy

A central dilemma in Participatory Action Research (PAR) is to establish participant decision authority on interventions while adhering to rigorous research practices. We faced this dilemma as part of an ongoing multi-site field research project in the corrections sector, where semi-autonomous union-based Design Teams (DTs) address worker health issues and design interventions. Employee focus groups and surveys elicited areas of concern, pointing to four topics in particular: overtime and sleep, work-family balance, physical fitness, and mental health; these were later expanded to eight priority areas. Quantitative rankings were generated by focus groups of line-level employees and supervisors. A multi-level, iterative priority selection process averaged focus group ratings of topic importance and also difficulty to address separately. Areas of job stress and mental health had highest importance but were also considered most difficult to address. A labor-management steering committee reviewed and endorsed the rankings and transmitted these to newly formed DTs. In principle, each DT was free to establish a different topic for initial intervention but they all chose the most important and difficult to address topics. This structured multi-tiered participatory process preserved ownership by all parties. Balancing participant autonomy and efficient prioritization of topics among multiple interest groups in this PAR effort met research methods needs and also made it easier for DTs to focus on the difficult and stigmatized area of mental health in the correctional workforce.

Impact of a Safe Resident Handling Program in Nursing Homes on Return-to-Work and Re-injury Outcomes Following Work Injury

Purpose This study examined the impact of a Safe Resident Handling Program (SRHP) on length of disability and re-injury, following work-related injuries of nursing home workers. Resident handling-related injuries and back injuries were of particular interest. Methods A large national nursing home corporation introduced a SRHP followed by three years of training for 136 centers. Lost-time workers' compensation claims (3 years pre-SRHP and 6 years post-SRHP) were evaluated. For each claim, length of first episode of disability and recurrence of disabling injury were evaluated over time. Differences were assessed using Chi square analyses and a generalized linear model, and "avoided" costs were projected. Results The SRHP had no impact on length of disability, but did appear to significantly reduce the rate of recurrence among resident handling-related injuries. As indemnity and medical costs were three times higher for claimants with recurrent disabling injuries, the SRHP resulted in significant "avoided" costs due to "avoided" recurrence. Conclusions In addition to reducing overall injury rates, SRHPs appear to improve long-term return-to-work success by reducing the rate of recurrent disabling injuries resulting in work disability. In this study, the impact was sustained over years, even after a formal training and implementation program ended. Since back pain is inherently a recurrent condition, results suggest that SRHPs help workers remain at work and return-to-work.

O3E.3 Changes in job security and mental health: an analysis of 14 annual waves of an australian working population panel survey

Background

There is increasing recognition of job insecurity as an emerging issue in public health. We sought to examine whether job security improvements were associated with improvements in mental health in a large, working population-representative repeated-measures panel study.

Methods

We used both within-person fixed effects (FE) and random effects (RE) regression to analyse data from 14 annual waves of a national Australian survey (19 169 persons, 1 06 942 observations). Mental Health Inventory-5 scores (outcome) were modeled in relation to self-reported job security (categorical, quintiles), adjusting for age, year, education, and job change in the past year.

Results

Both FE and RE models showed stepwise improvements in MHI-5 scores with improving job security, with stronger exposure-outcome relationships in the RE models, and for men compared to women. All models showed roughly monotonic improvements in MHI-5 score by quintile of improvement in job security. The strongest relationship was observed in the RE model for males: for a one-quintile improvement in job security, beta=2.06 [1.67, 2.46], and the following for two- (3.94 [3.54, 4.34]), three- (5.82 [5.40, 6.24]), and four- (7.18 [6.71, 7.64]) quintile improvements. The FE model for males produced slightly smaller coefficients, reaching a maximum of 5.55 [5.06, 6.05] for a four-quintile improvement.

Conclusions

This Australian national panel study showed a strong dose-response relationship between job security and depression and anxiety symptoms. Stronger causal inference over previous observational research is supported by the dose-response finding and the relative consistency of the FE and RE results. Policy and practice intervention to improve job security could benefit population health.

Occupational biomechanical risk factors for radial nerve entrapment in a 13-year prospective study among male construction workers

Objectives

The aim was to assess the association between occupational biomechanical exposure and the occurrence of radial nerve entrapment (RNE) in construction workers over a 13-year follow-up period.

Methods

A cohort of 229 707 male construction workers who participated in a national occupational health surveillance programme (1971–1993) was examined prospectively (2001–2013) for RNE. Height, weight, age, smoking status and job title (construction trade) were obtained on health examination. RNE case status was defined by surgical release of RNE, with data from the Swedish national registry for out-patient surgery records. A job exposure matrix was developed, and biomechanical exposure estimates were assigned according to job title. Highly correlated exposures were summed into biomechanical exposure scores. Negative binomial models were used to estimate the relative risks (RR) (incidence rate ratios) of RNE surgical release for the biomechanical factors and exposure sum scores. Predicted incidence was assessed for each exposure score modelled as a continuous variable to assess exposure–response relationships.

Results

The total incidence rate of surgically treated RNE over the 13-year observation period was 3.53 cases per 100 000 person-years. There were 92 cases with occupational information. Increased risk for RNE was seen in workers with elevated hand-grip forces (RR=1.79, 95% CI 0.97 to 3.28) and exposure to hand-arm vibration (RR=1.47, 95% CI 1.08 to 2.00).

Conclusions

Occupational exposure to forceful handgrip work and vibration increased the risk for surgical treatment of RNE.

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.

"Working on Wellness:" protocol for a worksite health promotion capacity-building program for employers

Background

In the United States, worksite wellness programs are more often offered by larger employers. The Massachusetts Working on Wellness (WoW) program is an innovative, statewide capacity-building model designed to increase the number of smaller employers (200 or fewer workers) adopting health promotion initiatives. This article describes the WoW program design and approaches to recruitment, implementation, and evaluation.

Methods/design

WoW provides employer training, technical assistance and seed funding, utilizing a Wellness Program Development framework based on recognized good practices. For-profit employers with 200 employees or fewer are eligible for and encouraged to apply for a Massachusetts Small Business Wellness Tax Credit. During the phase described in this paper, employer organizations applied to the program and committed to designating a champion responsible for program implementation. Interventions were to include policy and environmental supports, as well as those targeting individual behavior change through raising awareness and education. Supports provided to employers included seed grants for qualifying activities (up to $10,000 with matching required), community linkages, data collection and organization-specific feedback tools, an on-line curriculum supplemented with technical assistance, and an expert webinar series. Data collection at multiple time points, from the initial application through program completion, provides information for evaluation of recruitment, planned and completed activities.

Discussion

This model is grounded in literature on good practices as well as in local knowledge about Massachusetts employers. It does not directly address the influence of working conditions, which can affect both worker participation and health behaviors. Implementation may be less successful with some organizations, such as those with many workers who are part-time or geographically distributed rather than in a centralized physical location. Program evaluation will assess the extent to which WoW achieves its goals. The data are expected to increase understanding of the needs of smaller employers and industries not traditionally implementing employee wellness programs.

The effect of strengthening health literacy in nursing homes on employee pain and consequences of pain ‒ a stepped-wedge intervention trial

Objective This study examined the effectiveness of a workplace health literacy intervention on pain intensity, bothersomeness of pain, and sickness absence. Methods The quasi-experimental stepped-wedge cluster trial evaluated an intervention with two elements: (i) courses for employees and management to organize a joint foundation of knowledge about pain prevention and management with communication tools, and (ii) structured dialogs between employee and supervisor, to develop action plans to prevent and reduce pain. Monthly measurements were taken of pain intensity (0-10 scale), bothersomeness (days/month), and pain-related absence (days/month). Results Six workplaces were recruited, and 88% of employees (509) participated in evaluations. At baseline, mean pain level was 4.0, mean bothersomeness was 3.8 days/month, and mean pain-related absence was 0.6 days/month. From linear mixed models, pain intensity was reduced by -0.28 [95% confidence interval (CI) -0.52- -0.04] corresponding to a 7% reduction. For employees with pain >3 at baseline, the reduction was -0.74 (95% CI -1.11- -0.38) or 12%. There was no significant mean change in bothersomeness or sickness absence among all employees. Conclusion This intervention was both feasible and effective in shifting the overall mean pain level downwards for the entire population by 7%, with an accentuated effect among employees with pain levels >3. Organizing health literacy in nursing homes might be a feasible and effective way to build work environment efforts targeting the needs of employees. Future studies should investigate whether organizing health literacy is effective in other workplace settings and for employees with other health challenges.

Nursing Home Employee and Resident Satisfaction and Resident Care Outcomes

BACKGROUND

Nursing home resident care is an ongoing topic of public discussion, and there is great interest in improving the quality of resident care. This study investigated the association between nursing home employees' job satisfaction and residents' satisfaction with care and medical outcomes.

METHODS

Employee and resident satisfaction were measured by questionnaire in 175 skilled nursing facilities in the eastern United States from 2005 to 2009. Facility-level data on residents' pressure ulcers, medically unexplained weight loss, and falls were obtained from the Centers for Medicare and Medicaid Services Long-Term Care Minimum Data Set. The association between employee satisfaction and resident satisfaction was examined with multiple and multilevel linear regression. Associations between employee satisfaction and the rates of pressure ulcers, weight loss, and falls were examined with simple and multilevel Poisson regression.

RESULTS

A 1-point increase in overall employee satisfaction was associated with an increase of 17.4 points (scale 0-100) in the satisfaction of residents and family members (p < 0.0001) and a 19% decrease in the incidence of resident falls, weight loss, and pressure ulcers combined (p < 0.0001), after adjusting for staffing ratio and percentage of resident-days paid by Medicaid.

CONCLUSION

Job satisfaction of nursing home employees is associated with lower rates of resident injuries and higher resident satisfaction with care. A supportive work environment may help increase quality of care in the nation's nursing homes.

Research Methodologies for Total Worker Health®: Proceedings From a Workshop

OBJECTIVE

There is growing interest in the NIOSH Total Worker Health program, specifically in the process of designing and implementing safer, health-promoting work and workplaces. A Total Worker Health (TWH) Research Methodology Workshop was convened to discuss research methods and future needs.

METHODS

Twenty-six experts in occupational safety and health and related fields reviewed and discussed current methodological and measurement issues and those showing promise.

RESULTS

TWH intervention studies face the same challenges as other workplace intervention studies and some unique ones. Examples are provided of different approaches and their applications to TWH intervention studies, and desired developments in the TWH literature.

CONCLUSIONS

This report discusses and outlines principles important to building the TWH intervention research base. Rigorous, valid methodologic, and measurement approaches are needed for TWH intervention as well as for basic/etiologic, translational, and surveillance research.

Knee pain in nursing home workers after implementation of a safe resident handling program

PURPOSE

Approximately 25-30% of nursing personnel experience knee pain (KP). We sought to identify physical and psychosocial work exposures, and personal factors related to prevalent, incident, and persistent KP 5-8 years after safe resident handing program (SRHP) implementation in nursing homes.

METHODS

Health and exposure information was obtained from worker surveys 5-6 years ("F5") and 7-8 years ("F6") post-SRHP implementation. Prevalent KP correlates were examined at F5; persistent and incident KP predictors were analyzed at F6, utilizing robust Poisson multivariable regression.

RESULTS

F5 KP prevalence (19.7%) was associated with combined physical exposures, and with either high job strain or low social support, in separate models. Two-year persistent KP was similarly associated with these psychosocial exposures. Being overweight was associated with KP in all analyses.

CONCLUSIONS

The SRHP program did not eliminate knee physical loading, which should be reduced to prevent nursing home worker KP. Workplace psychosocial exposures (high job strain, low social support) also appeared germane.

Occupational biomechanical risk factors for surgically treated ulnar nerve entrapment in a prospective study of male construction workers

Objectives The aim of this study was to determine the association between occupational biomechanical exposures and occurrence of surgically treated ulnar nerve entrapment (UNE). Methods A cohort of 229 689 male construction workers who participated in a national occupational health surveillance program (1971-1993) were examined prospectively over a 13-year case ascertainment period (2001-2013) for surgically treated UNE. Job title (construction trade), smoking status, height, weight and age were recorded on examination. Job titles were merged into occupational groups of workers performing similar work tasks and having similar training. Occupational biomechanical exposure estimates were assigned to each occupational group with a job exposure matrix (JEM) developed for the study. Negative binomial models were used to assess the relative risks for each biomechanical exposure and the sums of highly correlated biomechanical exposures. Surgical treatment of UNE was determined via a linkage with the Swedish Hospital Outpatient Surgery Register. Results There were 555 cases of surgically treated UNE within the cohort. Workers exposed to forceful hand-grip factors had a 1.4-fold higher relative risk (95% CI 1.18-1.63) of undergoing surgical treatment for UNE compared to unexposed workers. Occupational groups comprising workers exposed to forceful hand-grip work showed the highest risks for UNE and included concrete workers, floor layers, ground preparatory workers, rock blasters, and sheet-metal workers. Conclusion Forceful hand-grip work increases the risk for surgically treated ulnar nerve entrapment.

Ergonomic evaluation of slide boards used by home care aides to assist client transfers

Home care aides risk musculoskeletal injury because they lift and move clients; the body weight of most adults exceeds the NIOSH recommended limit for lifting. Methods to reduce manual patient lifting in institutional settings are often technically or economically infeasible in home care. Our goal was to identify suitable, safe, low-technology transfer devices for home care use. Sixteen experienced home care aides performed client transfers from wheelchair to bed (upward) and bed to wheelchair (downward) in a simulated home care environment (laboratory), using four different slide boards and by hand without a device. Aides' hand forces were measured during client transfers; aides also evaluated usability of each board. Hand forces exerted while using slide boards were mostly lower than in manual transfer, and forces were lower in downward versus upward transfers. Aides judged a board with a sliding mechanism easier to use than boards without a sliding mechanism. Practitioner Summary: This paper provides quantitative biomechanical measurements showing that slide boards reduced the hand forces needed by home care aides to transfer clients from bed to wheel chair and vice versa, compared to manual lifting. Using a semi-quantitative usability survey, aides identified boards with a sliding mechanism easiest to use.

Dissemination and Implementation Research for Occupational Safety and Health

The translation of evidence-based health innovations into real-world practice is both incomplete and exceedingly slow. This represents a poor return on research investment dollars for the general public. U.S. funders of health sciences research (e.g., NIH, CDC, NIOSH) are increasingly calling for dissemination plans, and to a lesser extent for dissemination and implementation (D&I) research, which are studies that examine the effectiveness of D&I efforts and strategies and the predictors of D&I success. For example, rather than merely broadcasting information about a preventable hazard, D&I research in occupational safety and health (OSH) might examine how employers or practitioners are most likely to receive and act upon that information. We propose here that D&I research should be seen as a dedicated and necessary area of study within OSH, as a way to generate new knowledge that can bridge the research-to-practice gap. We present D&I concepts, frameworks, and examples that can increase the capacity of OSH professionals to conduct D&I research and accelerate the translation of research findings into meaningful everyday practice to improve worker safety and health.

Injuries and Assaults in a Long-Term Psychiatric Care Facility: An Epidemiologic Study

The objectives of this study were to document the high rates of acute injuries and physical assaults among nurses and certified nursing assistants working in long-term psychiatric care facilities and to identify risk factors for assaults and injuries to inform prevention strategies. A mixed-design cohort study was conducted. Acute injury and physical assault data were obtained from administrative records. Using staff rosters and schedule records, incidence rates were calculated by job title, gender, shift, and floor. Rates were also reported by severity, body part, type, and nature. Targeted interviews with staff members provided measures of physical lifting and resident combativeness. Injury rates were calculated by degree of lifting and assault rates were calculated by degree of resident combativeness. Overall rates of injuries (55.6 per 100 person-years) and assaults (67.3 per 100 person-years) were substantially higher than expected. Predictably, injuries were associated with resident lifting and assaults were associated with contact with combative residents. A higher risk of assault was found among women and higher risks of injury and assault were observed among full-time employees compared to per diem or pool agency workers. In addition, weekend shifts were found to have a higher rate of injuries and a lower rate of assaults than weekday shifts. In similar longterm care facilities with psychiatric populations, efforts should be made to reduce lifting and avoid circumstances that agitate residents. Work organization factors should be taken into consideration when developing interventions.

Associations Among Health Care Workplace Safety, Resident Satisfaction, and Quality of Care in Long-Term Care Facilities

OBJECTIVE

We performed an integrated cross-sectional analysis of relationships between long-term care work environments, employee and resident satisfaction, and quality of patient care.

METHODS

Facility-level data came from a network of 203 skilled nursing facilities in 13 states in the eastern United States owned or managed by one company. K-means cluster analysis was applied to investigate clustered associations between safe resident handling program (SRHP) performance, resident care outcomes, employee satisfaction, rates of workers' compensation claims, and resident satisfaction.

RESULTS

Facilities in the better-performing cluster were found to have better patient care outcomes and resident satisfaction; lower rates of workers compensation claims; better SRHP performance; higher employee retention; and greater worker job satisfaction and engagement.

CONCLUSION

The observed clustered relationships support the utility of integrated performance assessment in long-term care facilities.

Predictors of Nursing Staff Voluntary Termination in Nursing Homes: A Case-Control Study

Workforce instability in the long-term care sector has raised wide attention about nursing staff turnover. Most attention has been devoted to understanding the relationship between facility’s characteristics and organizational turnover. This case-control study examined the contribution of work characteristics to individual staff turnover. Surveys were collected with nursing staff in 18 for-profit nursing homes on up to five occasions between 2006 and 2012. A list of nursing staff voluntarily terminating jobs was provided by the company. Cases and controls (628 of each) were selected from survey respondents by matching on age, job category, and survey occasion. Multiple predictor conditional logistic regression models showed that evening shift work (hazards ratio [HR] = 2.00, p < .01) and shift length > 8 hr (HR = 1.42, p < .05) were contributing factors to voluntary termination. This study provides different perspectives of nursing staff voluntary termination in nursing homes. Future qualitative research would be valuable to explore and understand nursing staff turnover in the health care industry.

Work-Family Conflict, Sleep, and Mental Health of Nursing Assistants Working in Nursing Homes

Work-family conflict is challenging for workers and may lead to depression, anxiety, and overall poor health. Sleep plays an important role in the maintenance of mental health; however, the role of sleep in the association between work-family conflict and mental health is not well-studied. Questionnaires were collected from 650 nursing assistants in 15 nursing homes. Multivariate linear regression modeling demonstrated that increased work-family conflict was associated with lower mental health scores (β = -2.56, p < .01). More work-family conflict was correlated with more job demands, less job control, less social support, and longer work hours. Poor sleep quality, but not short sleep duration, mediated the association between work-family conflict and mental health. Workplace interventions to improve nursing assistants' mental health should increase their control over work schedules and responsibilities, provide support to meet their work and family needs, and address healthy sleep practices.

Associations between safety climate and safety management practices in the construction industry

BACKGROUND

Safety climate, a group-level measure of workers' perceptions regarding management's safety priorities, has been suggested as a key predictor of safety outcomes. However, its relationship with actual injury rates is inconsistent. We posit that safety climate may instead be a parallel outcome of workplace safety practices, rather than a determinant of workers' safety behaviors or outcomes.

METHODS

Using a sample of 25 commercial construction companies in Colombia, selected by injury rate stratum (high, medium, low), we examined the relationship between workers' safety climate perceptions and safety management practices (SMPs) reported by safety officers.

RESULTS

Workers' perceptions of safety climate were independent of their own company's implementation of SMPs, as measured here, and its injury rates. However, injury rates were negatively related to the implementation of SMPs.

CONCLUSIONS

Safety management practices may be more important than workers' perceptions of safety climate as direct predictors of injury rates.
