    Preventing Dump Truck-Related Injuries and Deaths During Construction: Guidance for Employers
    National Institute for Occupational Safety and Health
    2023/06/01 | NIOSH Numbered Publications
    Injuries from dump trucks led to the deaths of 809 construction and extraction workers from 2011 to 2020. Those operating dump trucks or working nearby are at risk of multiple hazards including struck-by, tip-over from loss of vehicle control, crushing, electrical, and falls. This fact sheet gives employers and workers ways to recognize and avoid t ...

    Since the inception of high explosives as an industrial tool, significant efforts have been made to understand the flow of energy from an explosive into its surroundings to maximize work produced while minimizing damaging effects. Many tools have been developed over the past century, such as the Hopkinson-Cranz (H-C) Scaling Formula, to define blas ...

    Pelvic floor disorders affect 24% of US women, and elevated intra-abdominal pressure may cause pelvic injury through musculoskeletal strain. Activity restrictions meant to reduce pelvic strain after traumatic events, such as childbirth, have shown little benefit to patients. Reported high variability in abdominal pressure suggests that technique pl ...

    Promise and Perils of Leader-Employee Check-Ins in Reducing Emotional Exhaustion in Primary Care Clinics: Quasi-Experimental and Qualitative Evidence

    2023/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Objective: To analyze the role of short (<30 minutes) and frequent (quarterly) check-ins between clinic leaders and employees in reducing emotional exhaustion. Methods: Three interrelated studies were conducted: a 3-year repeated cross-sectional survey at 10 primary care clinics (n=505; we compared emotional exhaustion, perceived stress, and values alignment among employees of a clinic where check-ins were conducted vs 9 control clinics); interviews with leaders and employees (n=10) regarding the check-ins process and experiences; and interviews with leaders and employees (n=10) after replicating the check-ins at a new clinic. Results: Outcomes were similar at baseline. After a year, emotional exhaustion was lower at the check-ins compared with control clinics (standardized mean difference, d, -0.71 [P<.05]). After 2 years, emotional exhaustion remained lower at the check-ins clinic, but this difference was not significant. The check-ins were associated with an increment in values alignment (2018 vs 2017, d=0.59 [P<.05]; 2019 vs 2017, d=0.76 [P<.05]). There were no differences for perceived job stress. Interviews indicated that work-life challenges were discussed in the check-ins. However, employees need confidentiality and to feel safe to do so. The replication suggested that the check-ins are feasible to implement even amid turbulent times. Conclusion: Periodic check-ins wherein leaders acknowledge and address work-life stressors might be a practical tactic to reduce emotional exhaustion in primary care clinics.
