Exploring psychological impact of hand-arm vibration syndrome (HAVS).

Abstract

Background: Hand-arm vibration syndrome (HAVS) is an occupational disease associated with long-term exposure to power tools leading to hand-transmitted vibration exposure. Prior research has focussed on physical manifestations with little known about the psychological impacts of HAVS.

Aims: To examine if HAVS severity and/or functional impairment is associated with psychological outcomes.

Methods: We conducted a cross-sectional study collecting data through a survey and retrospective chart review of workers being assessed for HAVS at an occupational medicine clinic. We collected information on demographics, work conditions, disease characteristics and physical and psychological outcomes as measured through validated instruments (SF-12, QuickDASH, GAD-2, PHQ-2). Descriptive statistics and bivariate analyses were followed by multivariable models to explore associations between mental health outcomes and predictor variables.

Results: Participants (N = 94; 56% response rate) were male with a mean age of 48.2 years. The majority (62%) worked in the mining sector, and 27% of participants reported feeling depressed and 35% reported showing little interest in or pleasure in doing things, while 28% reported clinically significant anxiety symptoms. In multivariable models, the QuickDASH, a measure of upper-extremity function and disability, was the only significant predictor of psychological outcomes.

Conclusions: Workers with HAVS have poorer mental health and physical functioning outcomes in comparison to the general population. Employers should consider tailored policies and interventions to address the mental health of workers with HAVS.
