Problem Construction work is hazardous and workers consistently rank in the top of all occupations and industries for illicit drug and heavy alcohol use. Methods Drug-testing programs were classified into three categories: no program, pre-employment/post-accident, and pre-employment/post-accident/random/ suspicion. We analyzed workers' compensation claims from 1,360 construction companies over a six-year period to assess the possible association of testing program with injury rate. Results Compared to no program, results respectively were RR = 0.85 (CI = 0.72 - 1.0) and RR = 0.97 (CI = 0.86 - 1.10) for all injuries, and RR = 0.78 (CI = 0.60 - 1.03) and RR = 1.01 (CI = 0.86 - 1.19) for lost-time injuries. Variability of results was exhibited across trade and union status, among other categories. Summary Drug-testing programs may be associated with lower, non-significant, injury rates in this population. Impact on Industry Drug-testing programs may be associated with lower injury rates, but care should be exercised to ensure accurate injury reporting, characterize underlying safety practices of a company, and to determine quality and consistency of testing.
