Total Prehospital Time and Tractor Injuries: A Nebraska State Trauma Registry Analysis

Area of Science:

• Agricultural Safety
• Trauma Research
• Public Health

Background:

• Agriculture is a high-risk industry, with tractor incidents causing significant traumatic injuries and fatalities.
• Injuries often occur in remote locations, increasing prehospital time and potentially affecting patient outcomes.
• Understanding prehospital time's impact on outcomes is crucial for resource allocation in agricultural safety.

Purpose of the Study:

• To investigate the relationship between prehospital time and hospital length of stay and mortality in Nebraska tractor-related injuries.
• To inform resource allocation strategies for managing tractor-related trauma in agricultural regions.

Main Methods:

• A 10-year retrospective study using The Nebraska State Trauma Registry.
• Analysis of 100 adult tractor-injury cases, evaluating mortality and length of stay.
• Logistic regression and negative binomial distribution models, adjusting for age, arrival status, and Injury Severity Score.

Main Results:

• Extremity injuries were most common (44%), with most patients having low Injury Severity Scores.
• The majority of injuries affected individuals not operating the tractor.
• Adjusted analysis revealed no significant association between total prehospital time and facility length of stay or mortality.

Conclusions:

• Despite challenges in accessing care in rural areas, prehospital time was not a significant predictor of outcomes in this study.
• Findings suggest that other factors may be more influential in outcomes for tractor-related injuries.
• Future research should differentiate outcomes based on specific tractor accident types, such as rollovers versus collisions.
