Work-related injuries in a state trauma registry: Relationship
between industry and drug screening
Terry L. Bunn, PhD, Svetla Slavova, PhD, and Andrew C. Bernard, MD, Lexington, Kentucky
BACKGROUND: Work-related injuries exert a great financial and economic burden on the US population. The study objectives were to identify
the industries and occupations associated with worker injuries and to determine the predictors for injured worker drug
screening in trauma centers.
METHODS: Work-related injury cases were selected using three criteria (expected payer source of workers’ compensation, industry-related
e-codes, and work-related indicator) from the Kentucky Trauma Registry data set for years 2008 to 2012. Descriptive analyses
and multiple logistic regression were performed on the work-related injury cases.
RESULTS: The ‘‘other services’’ and construction industry sectors accounted for the highest number of work-related cases. Drugs were
detected in 55% of all drug-screened work-related trauma cases. Higher percentages of injured workers tested positive for
drugs in the natural resources and mining, transportation and public utilities, and construction industries. In comparison, higher
percentages of injured workers in the other services as well as transportation and public utilities industries were drug screened.
Treatment at Level I trauma centers and Glasgow Coma Scale (GCS) scores indicating a coma or severe brain injury were both
significant independent predictors for being screened for drugs; industry was not a significant predictor for being drug
screened. The injured worker was more likely to be drug screened if the worker had a greater than mild injury, regardless of
whether the worker was an interfacility transfer.
CONCLUSION: These findings indicate that there may be elevated drug use or abuse in natural resources and mining, transportation and public
utilities, as well as construction industry workers; improved identification of the specific drug types in positive drug screen
results of injured workers is needed to better target prevention efforts. (J Trauma Acute Care Surg. 2014;77: 280Y285.

ork-related injuries exert a great financial and economic
burden on the US population. In 2010, the total costs of
work injuries were estimated to be $176.9 billion, including
wage and productivity losses, medical costs, and administra-
tive costs.
1
According to the National Academy of Social In-
surance, workers’ compensation programs alone paid $57.5
billion in benefits and $28.1 billion in medical benefits asso-
ciated with work-related injuries in the United States in the
year 2010.
2
State trauma registry data have the potential to identify
worker injuries by industry and occupation since it contains an
indicator to ascertain work relatedness and have information on the
industry and occupation categories of the injured worker.
3
The
combination of the work-related indicator, workers’ compensation
as the expected payer, and work-related e-codes is associated with
high specificity in the surveillance of work-related injuries.

Data
from state trauma registries are also useful for the identification of
the presence of drugs and/or alcohol associated with injuries.
Approximately 9.3% of adolescent blunt trauma patients admitted
to two local Level I trauma centers had positive toxicology results
for drugs and alcohol.
5
In another study, trauma patients in an
academic Level I trauma center with positive drug and/or alcohol
screen results and penetrating trauma were more likely to have
arrived dead to the hospital compared with those with negative
drug and alcohol screen results.
6
The prevalence of illicit drug use in the workforce has
been estimated to be 14.1%, while the estimated prevalence of
illicit drug use in the workplace has been estimated at 3.1%.

The objectives of the present study were to identify the in-
dustries and occupations associated with worker injuries treated
in trauma centers and to determine the predictors for injured
worker drug screening in trauma centers.
PATIENTS AND METHODS
Trauma Registry Data
Data for the present study were obtained from the Kentucky
Trauma Registry database for years 2008 to 2012 and represent
the most severe traumatic injuries treated at Kentucky trauma
centers and reported to the Kentucky Trauma Registry. Trauma
registry data were collected according to recommended ele-
ments in National Trauma Data Standards (NTDS).
