Area of Science:

  • Occupational Health
  • Gerontology
  • Safety Science

Background:

  • Assessing occupational fall risk in older workers lacks user-friendly tools.
  • Older workers face unique challenges regarding workplace safety and fall prevention.

Purpose of the Study:

  • To develop and validate the Occupational Fall Risk Assessment Tool (OFRAT).
  • To assess the predictive validity and reliability of OFRAT in older workers.

Main Methods:

  • Developed OFRAT by summing risk factors: age, sex, fall history, physical work, diabetes, medications, vision, hearing, executive function, and stepping speed.
  • Assessed 1113 older workers (≥60 years) in Japan, followed for 1 year for occupational falls.
  • Evaluated test-retest reliability with 30 participants and predictive validity using regression models.

Main Results:

  • 112 participants experienced 214 falls during work.
  • Higher OFRAT grades significantly correlated with increased fall incidence (e.g., high risk: 6.12 times higher).
  • OFRAT demonstrated strong reliability (ICC=0.86) and validity (weighted kappa=0.74).

Conclusions:

  • The Occupational Fall Risk Assessment Tool (OFRAT) is a valid and reliable instrument.
  • OFRAT can aid occupational physicians in developing fall prevention strategies for older workers.
