Rural versus urban trauma: demographic influences on autopsy rates

Area of Science:

• Trauma Surgery
• Forensic Pathology
• Public Health

Background:

• Autopsies are crucial for quality assurance in trauma care.
• Research on autopsy rates in rural trauma centers is limited, despite higher injury death rates in rural areas.
• Rural trauma centers have distinct patient demographics and characteristics compared to urban centers.

Purpose of the Study:

• To characterize trauma patients at a rural trauma center (University of Iowa Hospitals and Clinics - UIHC) who underwent autopsy.
• To identify demographic differences between autopsied and non-autopsied trauma patients.
• To compare autopsy rates and patient demographics with urban trauma center data.

Main Methods:

• Demographic study of 496 trauma deaths from January 2002 to May 2007.
• Data collected included age, race, and length of hospital stay for autopsied (231) and non-autopsied patients.
• Univariate and multivariate linear regression models were used for analysis; comparisons were made with urban center reports.

Main Results:

• Autopsied patients were significantly younger (mean age 45 vs. 71 years) and had shorter hospital stays (1 vs. 4 days).
• Autopsy rates were lower for blunt trauma (42%) compared to penetrating (67%) or burn trauma (56%).
• The rural center had lower autopsy rates, a higher mean patient age, more blunt trauma cases, and fewer males compared to urban centers.

Conclusions:

• Rural trauma centers like UIHC have unique demographics (older patients, more blunt trauma, fewer males) contributing to lower autopsy rates.
• Older patients, those with longer hospital stays (>48 hours), and blunt trauma victims were less likely to receive an autopsy.
• The demographic profile of trauma patients undergoing autopsy in rural settings often mirrors that of urban populations, explaining variations in autopsy rates.
