International Total Worker Health: Applicability to Agribusiness in Latin America

The Total Worker Health® (TWH) approach: a systematic review of its application in different occupational settings

BACKGROUND

The National Institute for Occupational Safety and Health (NIOSH), in 2011, developed the "Total Worker Health®" (TWH) as a holistic approach to protect and promote the workers' safety, health, and well-being. After over ten years from the TWH development, the aim of the present systematic review is to provide a comprehensive overview of the worldwide TWH initiatives.

METHODS

PubMed, Scopus and ISI Web of Science were searched for TWH studies published up to the 31st of July 2023, and 43 investigations could be included. The review was registered on the International prospective register of systematic reviews PROSPERO with the reference number CRD42023416972.

RESULTS

Issues that emerged as relevant for the TWH operationalization were the awareness about the TWH approach and fundamentals, the leadership commitment, and a participatory engagement of the workforce: these aspects all contributed to acceptable and effective setting oriented TWH plans, specifically tailored on the peculiarities of the workplace, including small enterprises and multiemployer worksites. Evaluation and continual improvement were reported as fundamental for the successful implementation of TWH initiatives. Limited resources for safety and health initiatives, in terms of time, people, and funds, together with difficulties in the identification of safety and health priorities and a poor participatory culture were recognized as obstacles to the TWH application. Training resulted the core component of the TWH leadership and workforce preparedness, with beneficial results in terms of safety culture and adoption of preventive measures.

CONCLUSIONS

Although interesting aspects emerged from our review, future longitudinal investigations should confirm the effectiveness, easy integration, and long-term sustainability of TWH models in different workplaces, in order to effectively support safe and health-enhancing works able to improve innovation and productivity.

Feasibility of a Capacity Building Organizational Intervention for Worker Safety and Well-being in the Transportation Industry: Pivoting to Address the COVID-19 Pandemic and Social and Political Unrest in Chile

OBJECTIVE

This study developed, implemented, and evaluated the feasibility of executing an organizational capacity building intervention to improve bus driver safety and well-being in a Chilean transportation company. Method: Through an implementation science lens and using a pre-experimental mixed methods study design, we assessed the feasibility of implementing a participatory organizational intervention designed to build organizational capacity. Result: We identified contextual factors that influenced the intervention mechanisms and intervention implementation and describe how the company adapted the approach for unexpected external factors during the COVID-19 pandemic and social and political unrest experienced in Chile. Conclusions: The intervention enabled the organization to create an agile organizational infrastructure that provided the organization's leadership with new ways to be nimbler and more responsive to workers' safety and well-being needs and was robust in responding to strong external forces that were undermining worker safety and well-being.

Integration of Total Worker Health ® Training for Occupational Health and Safety Professionals With Efforts to Promote Worker Health, Safety, and Well-being in Mexico

OBJECTIVE

We sought to test whether a 2-week Total Worker Health (TWH) training mapped to TWH education competencies could be administered to a Mexican audience of occupational safety and health professionals and could lead to positive changes to knowledge and behaviors.

METHODS

This study used robust program evaluation methods collected before and after each of the nine training days and at the end of the course.

RESULTS

Overall course quality received a mean score of 4.6 (SD = 0.6) and 98.8% of participants agreed that their TWH knowledge increased. All participants intended to make at least one change to their professional practice, most frequently helping companies assess their organizational culture to support health, safety, and well-being.

CONCLUSIONS

This TWH training was well received and led to positive self-reported increase in knowledge and abilities to influence workers' health, safety, and well-being.

Work Ability and Well-Being Management and Its Barriers and Facilitators in Multinational Organizations: A Scoping Review

The aim of this scoping review was to identify effective workplace programs for work ability and well-being management and its barriers and facilitators in multinational organizations. The PubMed, Embase, and Web of Science databases were searched from 1974 through February 2023 to identify quantitative and qualitative studies on the management of work ability and well-being, and related outcomes including presenteeism, absenteeism, productivity loss, and healthy practices, conducted in a multinational organization or company. The titles and abstracts of over 11,000 publications were screened, and 10 studies fulfilling the inclusion criteria were included in the review. The management of work ability and well-being in multinational companies requires leadership support and commitment, effective communication, employee health awareness and engagement, comprehensive personalized health risk and condition assessments, and the management of risk factors and occupational and non-occupational health conditions. Financial constraints, high workloads, competing priorities, a lack of effective communication, a lack of worksite managers' motivation, employees' language barriers, high worksite managers' turnover, and a decline in the support of senior managers are considered as barriers, and the presence of existing participatory practices is considered as a facilitator of participation in workplace health and well-being interventions in multinational companies. This review suggests that the management of work ability and well-being in multinational companies should go beyond health promotion and include comprehensive personalized health risk and health condition assessments and management.

Automation, Climate Change, and the Future of Farm Work: Cross-Disciplinary Lessons for Studying Dynamic Changes in Agricultural Health and Safety

In this review, we first assess the state of agricultural health and safety research as it pertains to the dynamic challenges facing automating agriculture on a warming planet. Then, we turn to social science fields such as rural sociology, science and technology studies, and environmental studies to leverage relevant insights on the introduction of new technologies, environmental risks, and associated workplace hazards. Increased rates of automation in agriculture alongside new risks associated with climate change create the need for anticipatory governance and adaptive research to study novel mechanisms of worker health and safety. The use of the PRISMA framework led to the 137 articles for our review. We identify three themes in the literature on agricultural health and safety: (1) adoption outcomes, (2) discrete cases of health risks, and (3) an emphasis on care and wellbeing in literature on dairy automation Our review led to the identification of research gaps, noting that current research (a) tends to examine these forces separately, instead of together, (b) has not made robust examination of these forces as socially embedded, and (c) has hesitated to examine the broad, transferable themes for how these forces work across industries. In response to these gaps, we suggest that attention to outside disciplines may provide agricultural health and safety research with a toolset to examine needed inquiry into the multiplicity of experiences of rural stakeholders, the industry specific problems arising from automation and climate change, and the socially embedded aspects of agricultural work in the future.

Occurrence of Occupational Injuries and Within Day Changes in Wet Bulb Temperature Among Sugarcane Harvesters

OBJECTIVE

Climate change has implications for human health worldwide, with workers in outdoor occupations in low- to middle-income countries shouldering the burden of increasing average temperatures and more frequent extreme heat days. An overlooked aspect of the human health impact is the relationship between heat exposure and increased risk of occupational injury. In this study, we examined the association between occupational injury occurrence and changes in outdoor temperatures through the workday among a cohort of Guatemalan sugarcane harvesters.

METHODS

Occupational injuries recorded for the 2014/2015 to 2017/2018 harvest seasons were collected from a large agribusiness employing male sugarcane harvesters in Southwest Guatemala. Wet Bulb Globe Temperature (WBGT) for the same period was collected from the El Balsamo weather station. We used a logistic mixed effects model to examine the association between injury occurrence and (1) the average WBGT during the hour injury was recorded, (2) the average WBGT during the hour prior to the injury being recorded, and (3) the change in the hourly average WBGT prior to the injury being recorded.

RESULTS

There were 155 injuries recorded during the study period. Injuries were recorded most often between 14:00 and 16:00 (n = 62, 40%) followed by 8:00 and 10:00 (n = 56, 36%). There were significant differences in the average hourly WBGT and the hour in which injuries were recorded (p-value <.001). There were no observable associations between average hourly WBGT (OR: 1.00, 95%CI: 0.94, 1.05; p-value: 0.87), lagged average hourly WBGT (OR: 1.01, 95%CI: 0.97, 1.05; p-value: 0.71), or change in average hourly WBGT (OR: 0.96, 95%CI: 0.89, 1.04; p-value: 0.35) and recorded occupational injury.

CONCLUSIONS

This is the first study that has examined how changes in WBGT throughout the day are related to occupational injury among agricultural workers. Although this study did not demonstrate an association, there is a need for future research to examine how various measurements of WBGT exposure are related to occupational injury in agricultural worker populations.

Workers and Climate Change: The Need for Academic–Industry Partnerships to Improve Agricultural Worker Health, Safety, and Wellbeing

Climate change will have negative consequences for human health worldwide. Agricultural workers are especially vulnerable to the health consequences of climate change. This communication demonstrates how a Total Worker Health® approach is utilized to protect Guatemalan agricultural workers from the negative health effects of climate change. DrPH researchers work alongside local partners to develop, implement, and evaluate climate adaptation strategies and other interventions to improve agricultural worker health, safety, and wellbeing. Training in public health ethics, communications, and leadership gives DrPH researchers the tools to help create successful academic–industry partnerships that increase local capacity and have sustainable public health impact.

Small + Safe + Well: lessons learned from a Total Worker Health® randomized intervention to promote organizational change in small business

BACKGROUND

Leadership commitment to worker safety and health is one of the most important factors when organizations develop and implement a Total Worker Health® approach. We aimed to assess the effectiveness of a Total Worker Health ("TWH") leadership development program that targeted owners and other senior-level leadership positions on changing organizational and worker outcomes from baseline to one-year later.

METHODS

The Small + Safe + Well study included small businesses from a variety of industries in the state of Colorado, USA that were participating in Health Links™. We designed a randomized waitlisted control comparison design (RCT) to evaluate the added benefit of a TWH leadership development program. An employer assessment tool was used to assess TWH policies and programs, and an employee health and safety survey was used to assess safety leadership and health leadership practices, safety climate and health climate, safety behaviors and health behaviors, and well-being. We used a linear mixed model framework with random effects for business and employee to assess the impact of intervention on the outcomes of interest.

RESULTS

Thirty-six businesses (37% retention) and 250 employees (9% retention) met the RCT study inclusion criteria and were included in the analysis. Businesses improved their TWH policies and programs score from baseline to one-year later, regardless of leadership intervention group assignment. Neither intervention group demonstrated improvements in employee-reported outcomes.

CONCLUSIONS

This study sought to address a gap in the literature regarding small business senior leadership development for TWH. Our study demonstrates many of the challenges of conducting studies focused on organizational change in workplaces, specifically in small businesses. When designing TWH intervention studies, researchers should consider how to best engage small business leaders in interventions and implementations early on, as well as methods that are well matched to measuring primary and secondary outcomes longitudinally. Future research is needed to test the feasibility and sustainability of TWH interventions in small business.

TRIAL REGISTRATION

The trial was retrospectively registered with ClinicalTrials.gov ( ID U19OH011227 ).

Attitudes of Company Executives toward a Comprehensive Workplace Health Management-Results of an Exploratory Cross-Sectional Study in Germany

Workplace health management (WHM) in Germany aims at maintaining and increasing the health and well-being of employees. Little is known about company executives’ attitudes toward WHM. To gain more insight, we conducted a large-scale survey in companies in the German county of Reutlingen in 2017. We sent a standardized questionnaire to 906 companies, containing inter alia 26 self-constructed declarative statements depicting company executives’ opinions on various WHM aspects; 222 questionnaires could be evaluated. By exploratory factor analysis we assigned the 26 items to six factors reflecting different attitudes toward WHM. Factor values were standardized to a scale from 0 to 10. The attitude ‘positive view of general health services in the company’, for example, achieved by far the lowest mean agreement (3.3 points). For the attitude ‘general skepticism toward WHM’, agreement and disagreement were balanced (5.0 points). Using multiple regression analyses, we searched for variables that could partially explain respondents’ agreement with attitudes. In conclusion, a general WHM skepticism was widespread, but not dominant. The idea that general health services should be offered in companies was predominantly rejected. Older respondents and respondents from smaller companies and craft enterprises were more skeptical than average about WHM and its possible extensions.

Dissemination and Implementation Science Approaches for Occupational Safety and Health Research: Implications for Advancing Total Worker Health

Total Worker Health^® (TWH), an initiative of the U.S. National Institute for Occupational Safety and Health, is defined as policies, programs, and practices that integrate protection from work-related health and safety hazards by promoting efforts that advance worker well-being. Interventions that apply the TWH paradigm improve workplace health more rapidly than wellness programs alone. Evidence of the barriers and facilitators to the adoption, implementation, and long-term maintenance of TWH programs is limited. Dissemination and implementation (D&I) science, the study of methods and strategies for bridging the gap between public health research and practice, can help address these system-, setting-, and worker-level factors to increase the uptake, impact, and sustainment of TWH activities. The purpose of this paper is to draw upon a synthesis of existing D&I science literature to provide TWH researchers and practitioners with: (1) an overview of D&I science; (2) a plain language explanation of key concepts in D&I science; (3) a case study example of moving a TWH intervention down the research-to-practice pipeline; and (4) a discussion of future opportunities for conducting D&I science in complex and dynamic workplace settings to increase worker safety, health, and well-being.
