Background:
Hand-arm vibration syndrome (HAVS) is caused by prolonged occupational exposure to hand-transmitted vibration. Although HAVS is preventable, disease awareness and prevention knowledge are lacking in high-risk workplaces; this may contribute to under-diagnosis, delays in seeking care, and poor health outcomes. Posters may be used to increase awareness in the workplace.
Objective:
To conduct a pilot survey in workers with HAVS about poster use in their workplaces, their recommendations for poster campaigns and training programs, and their evaluation of HAVS awareness and prevention posters.
Methods:
All eligible HAVS patients in the Occupational Health Clinic at St. Michael's Hospital, in Toronto, Canada, were asked to complete a questionnaire on workplace poster use and to evaluate a set of HAVS posters.
Results:
Fifty workers participated; almost all were males, aged 50 and older, working in construction. Most indicated having non-HAVS specific awareness posters in their workplaces. There was a positive evaluation of the design, content, and potential usefulness of the posters. The poster depicting finger blanching stood out most. The poster depicting anti-vibration gloves rated highest for relatability and effectiveness at conveying disease importance.
Conclusions:
Participants supported the proposed use of industry-specific HAVS awareness posters in their workplaces. Future research should evaluate the effectiveness of these posters in the workplace.
