Background

Numerous studies have focused on bus drivers’ occupational diseases; however, limited data consider the realm of bus operators’ work-related injuries and associated risk factors. Thus, this study addresses unintentional injury among bus operators in Minnesota and exposures that increase their risk.

Methods

Demographic, work-related, and injury information was obtained from a transit company for a five-year period (Dec 1, 2006 to Dec 31, 2011). Estimates of rates, per 100 Full Time Equivalents (FTEs) and adjusted Hazard Ratios (HRs), with associated 95% Confidence Intervals (C.I.), were generated, using Generalized Estimated Equations and Cox Proportional Hazards models, respectively.

Results

A total of 2,095 bus operators were included in this study. The overall unintentional injury rate with 95% C.I. was 17.8 [16.1, 19.7] per 100 FTEs. Multivariable analysis identified increased risks for operators who were: female, compared to male (HR=2.4 [2.0, 2.8]); worked less than seven, compared to seven to less than 12 hours per day (HR=4.6 [3.8, 5.5]); and drove less than seven compared to seven to less than 12 hours per day (HR=3.2 [2.7, 3.8]). Operators who worked split, versus straight shifts, demonstrated a suggestive increased risk (HR=1.2 [1.0, 1.4]). Bus operators also tended to have an increased risk when driving limited versus regular bus routes (HR=1.36 [1.0, 1.8]).

Conclusions

Results of this study serve as a basis for further studies and can inform the development of targeted intervention strategies to reduce occupational injuries relevant to bus operators.
