Total Worker Health® Intervention Research Employs the Hierarchy of Controls

Friday January 11, 2019 at 11:00 AM PT, 2:00 PM ET


The US National Institute for Occupational Safety and Health (NIOSH) has redefined occupational safety and health for the US as safety, health and well-being, which it has termed Total Worker Health® (TWH). It has adapted the traditional Hierarchy of Controls, a prioritization strategy validated over decades of safety interventions, to apply to TWH efforts. A literature review identified TWH interventions and categorized them according to the controls used from the adapted Hierarchy of Controls.

You wil learn

  • ​Rationale for a Total Worker Health (TWH) intervention
  • Restatement of the hierarchy of controls by NIOSH to reflect the TWH definition
  • The range of TWH interventions that have had a positive impact on workplaces and workforces
  • Which types of controls are used most frequently in TWH interventions
  • How some TWH interventions used multiple controls while others used only one

Take-home messages

  • TWH intervention tactics from each Hierarchy level have produced measurable, positive changes in the workplace
  • The majority of TWH interventions have employed control tactics or methods classified as Educate, the least preferred tactic
  • Most interventions used more than one control strategy from the Hierarchy of Controls
  • Most interventions were aimed at employees, often combined with supervisors​​
