Insights
Urban trauma center admissions reveal key demographic and injury patterns. Understanding these trends in trauma care is crucial for system design and resource allocation.
Area of Science:
- Trauma Surgery
- Public Health
- Emergency Medicine
Background:
- Trauma admission and hospitalization patterns significantly impact urban trauma care systems.
- Analyzing these patterns is essential for effective system organization and utilization.
Purpose of the Study:
- To identify and analyze admission and demographic patterns in an urban Level I trauma center.
- To provide data for the utilization, modification, and future design of trauma systems.
Main Methods:
- Retrospective review of 2029 trauma admissions to a Level I trauma center from 1993 to 1996.
- Analysis of patient demographics, mechanisms of injury, admission timing, length of stay, and mortality.
Main Results:
- Most patients were young males; motor vehicle accidents and falls were leading injury mechanisms.
- Admissions peaked during evenings, weekends, and summer/fall months.
- A decrease in overall admissions was driven by reduced penetrating trauma; pediatric penetrating trauma incidence mirrored adults.
Conclusions:
- Identified demographic and admission patterns offer insights into urban trauma care.
- Distinct patterns in early (penetrating) and late (blunt) trauma mortality were observed.
- Findings can inform trauma system planning, resource allocation, and operational adjustments.
Abstract:
Because trauma admission and hospitalization patterns have profound effects on the organization and utilization of urban trauma-care systems, the objective of this study was to identify and analyze these patterns. As an example, admissions to an urban Level I trauma center were reviewed. Retrospective review of all 2029 trauma admissions to a Level I trauma center was conducted from 1993 to 1996. The result was that most trauma patients were young (40% < 30 years of age) and male (74%). Mechanisms of injury were motor vehicle accident (36%), fall (27%), gunshot (17%), stab (7%), assault (6%), and swimming or diving accident (3%). Half of the patients were directly admitted from the scene. Injury Severity Score, length of stay, and mortality were 14.1 +/- 0.3, 10.5 +/- 0.3 days, and 5.1%, respectively. Admissions tended to occur more frequently between 4:00 PM and midnight (46%), between Friday and Sunday (52%), and between July and October (41%). The following patterns were identified: admissions per year decreased (-21%) because of reduced penetrating trauma (-43%, P < .01); pediatric patients (< 15 years) had similar incidence of penetrating trauma as adults (ages 15-45). Length of stay for all mechanisms of injury was not statistically different; most mortalities occurred within the first day (33%, P < .01) or after 6 days (36%, P < .01); early mortality was mainly due to penetrating injury (74%, P < .01), whereas late mortality was related to blunt trauma (92%, P < .01). The conclusion was that admission and demographic patterns were identified, which may be useful in the utilization, modification, and future design of trauma systems.
