Building capacity for Total Worker Health in practice: Emerging from our landmark Oregon Total Worker Health® Alliance [OHWC’s home Institute, SAIF (Oregon workers’ compensation provider and NIOSH TWH Affiliate), and Oregon OSHA], our practitioner-focused trainings have continued to reach new audiences in our first year of the new cycle. We reached ~340 practitioners and held 14  sessions. Learn about the various TWH course offerings.

Testimonials from our course attendees:
WOW! THANK YOU! This training was on my Safety and Wellbeing bucket list! I was so thrilled to participate! I am going to hang this on my wall with pride!  I have truly believed in this approach for years because it makes so much sense!  I am so  looking forward to finding opportunities to share this with others! I know it will make positive impacts to help keep people safe and healthy!  I plan to recommend  this as a valuable tool when helping companies develop their Safety, Wellbeing, and Retention strategies.  I know it will be a win-win and now  just need to find these future partners! Linda S.

 Great stuff and as you stated, wonderful sharing and networking.  Looking forward to our next connection and the train the trainer in 2023. Jamal A.

This is a picture of our Summer Institute

Summer Institute: Total Worker Health® approaches in industry and academia: Key elements and implementation (July 19, 2022, 85 attendees). As research increasingly shows evidence for Total Worker Health® as an effective approach for worker well-being, we are faced with a growing need to educate and train students and industry professionals on TWH concepts and implementation. Our day-long 2022 Summer Institute highlighted current opportunities to learn and implement TWH concepts and strategies.  Welcoming attendees from academia and industry, the morning session included a workshop-style deep dive into the TWH approach by the Oregon Total Worker Health Alliance, and in the afternoon, a panel of industry professionals shared their experiences with implementing TWH strategies within their organization.  Watch recordings here.

Testimonials from our Summer Institute attendees:
This was a wonderful event. Everything that we learned can be applied to the workplace or at least the working knowledge of someone doing research.

New concepts that keep(s) resonating: WELL BEING HAZARDS. It truly captures all that needs to be prevented for TOTAL WORKER HEALTH.

This is a picture showing a group of people.

Expanding our industries and increasing our reach: OHWC’s research projects in 2021-2026 bring Total Worker Health to new worker populations as our research journey draws us toward unique issues and work experiences of firefighters, home care workers, healthcare workers, and utility and manufacturing workers. Through our Alliance-led trainings, we have reached practitioners across the United States and Europe. Dr. Emily Huang, who leads the Total Worker Health Climate Scale Study, shared her TWH Climate expertise with professionals in Malaysia and a construction site in Singapore. 

OHWC members have presented at a number of conferences thus far in our cycle. Some of these include the American Society of Safety Professionals (ASSP)’s Safety 21 Conference, Health Enhancement Research Organization (HERO) Forum, HERO’s Healthy Workplaces Healthy Communities committee, HERO’s Workplace Mental Health and Well-Being Committee, Fall Think Tank 2022 HERO Forum, Work and Family Researchers Network 2022, Northwest Occupational Health Conference, APA Work, Stress, and Health 2021, European Academy of Occupational Health Psychology, Oregon Public Health Association, NIOSH Extramural Community of Practice quarterly meeting, NIOSH’s all-extramural centers meeting, Region X Voluntary Protection Program Conference in Boise, ID, Occupational Health and Safety Magazine virtual summit, Blue Mountain Occupational Safety and Health Conference in Pendleton, OR, and the 2022 American Industrial Hygiene Conference in Nashville, TN.

Responding to the mental health crisis in our workforce and well-being needs of first responders: Three of OHWC’s four research projects in our 2021-2026 cycle are supported through NIOSH’s funding from the American Rescue Plan, which is addressing mental health in health care workers and first responders. Kicking off in FY22, these projects will lead us to examine shift schedules and health among firefighters (led by Dr. Nicole Bowles), adapt an intervention for pain management among home care workers (led by Dr. Ryan Olson), and develop an intervention to address burnout in healthcare workers (led by Drs. David Hurtado and Abigail Lenhart). Aside from research, OHWC’s Co-Director, Dr. Leslie Hammer has been called on to provide expert guidance on workplace mental health, advising the US Surgeon General, consulting for the American Psychological Association, and presenting for NIOSH. She has also published The Missing Link: The Role of the Workplace in Mental Health.

Growing our Diversity, Equity, and Inclusion (DEI) focus: We continue to make concerted efforts to meaningfully adopt a DEI-informed approach in OHWC’s planning, evaluation, research, and outreach activities. This takes shape in a number of ways at OHWC and our home, the Oregon Institute of Occupational Health Sciences. For example, we dedicate time during meetings to check in with each other following unsettling events around us, and discuss how it impacts us in our pursuit of worker well-being. We plan DEI-focused outreach and education events and continue to engage in a state-wide coalition called the Safe From Hate Alliance, which is focused on preventing harassment and prejudice among people of color in trade occupations and improving retention and safety across industries. Further, we continue to commit a standing item in our monthly Internal Steering Committee meetings that focuses on integrating DEI-informed strategies into our work – in this past year, we have discussed demographic data in our research, consent forms, race identity within Hispanic communities, equity in publishing, Public Psychology, the White House Climate and Economic Justice Screening Tool, and gender and sex in physiological measurements. We also presented with wellness and benefits professionals such as HERO on applying Total Worker Health approaches to develop inclusive workplace policies and practices with regard to gender identity and expression.

Celebrating awards, new members, and other news!  OHWC Co-Director, Dr. Leslie Hammer, received a Distinguished Faculty Award from our home institution, OHSU. Leslie’s award is a recognition of her outstanding applied research in a largely medical and bench sciences-driven institution and reflects her extensive contributions to the field of worker well-being. Dr. Hammer also took on an additional role as Associate Director of Applied Research at the Oregon Institute of Occupational Health Sciences. This new role complements her role as OHWC’s Co-Director. Finally, the Institute also welcomes a new Outreach Director, Dr. Erin Flynn. Erin leads the outreach team’s continued and evolving efforts toward increasing the public health impact of our worker safety, health, and well-being research. Read more about Erin on our blog.
