(417) Temporal Changes in Injury Patterns and Outcomes in Obstetric Trauma at One Academic Center (1994–2023)

Wednesday, February 11, 2026
3:30 PM - 5:00 PM  
Objective:
Trauma is the leading cause of nonobstetric death among pregnant women. But management of obstetrical traumas can vary from the general population and require special attention. Trauma centers with readily available obstetrical services are ideal for the management of obstetrical patients with traumatic injuries. The objective of this study was to investigate long-term trends in mortality, mechanism of trauma, and rate of admissions in pregnant patients.

Study Design:
We conducted a retrospective analysis of obstetrical traumas at a single academic level one trauma center over 29 years (1994-2023). Demographic factors, injury characteristics, admitting service, age at time of trauma, and admitting service were examined for temporal trends over ten-year increments. Temporal changes in mechanism of injury, rate of admission, and admitting service were analyzed using logistic regression analysis in ten-year increments. Factors associated with independent temporal trends were analyzed using ordinal logistic regression modeling. 

Results:

During the study period, there were 1,688 encounters for obstetrical trauma, with a predominance of motor vehicle collisions (50.5%) and falls (29.7%). Trends were observed with increases in motor vehicle accidents (MVA) (p< 0.001) & all-terrain vehicle accidents (p< 0.003). Additional trends were noted with decreases in assaults (p< 0.002), falls (p< 0.00001), and deaths (p=0.3). 



Over the study period in ten-year increments, lower rates of admission to the hospital and admission to the obstetrical service was observed.  


Conclusion:
Throughout the decades, with advancement in science and changes in medical society guidelines; there has been a decrease in the amount of posttraumatic pregnant patients admitted and a statistically significant decrease in gravid patients admitted to the surgical service (general surgery or acute trauma care).
