Abstract

Background:

Work-related injuries in the U.S. have steadily declined over the past three decades.

Objective:

The aim of this study was to compare trends of the most frequently injured body parts from a beverage company over an 8-year study period (2008 to 2015).

Method:

Work-related injury claims with more than 3 days of missed work (N = 20,203) were classified into body part groups, including low back, knee, shoulder, and all other(s). Descriptive statistics and linear models were used to evaluate trends over time.

Results:

The total number of injuries decreased from 6.57 per 100 to 3.79 per 100 employees from 2008 to 2015. Proportion of low back injuries decreased from 22.0% to 15.4% (P < 0.001) over the study period. Proportionally, knee(s), shoulder(s), and all other injuries increased, but the changes did not reach statistical significance.

Conclusion:

Low back injuries decreased at a faster rate than knee, shoulder, and all other injuries.
