Key result
Hospital Shock Index ≥1.0 linked to ~18-fold higher odds of ruptured AAA and greater mortality.
Why the study?
A ruptured abdominal aortic aneurysm is life-threatening with high mortality, and the predictive and prognostic value of the Shock Index for suspected rAAA was unclear.
Does a Shock Index ≥ 1.0 predict the presence of a ruptured abdominal aortic aneurysm, need for packed cells, and mortality in patients with suspected rAAA?
Observational (n=313)
No
Does a Shock Index ≥ 1.0 predict the presence of a ruptured abdominal aortic aneurysm, need for packed cells, and mortality in patients with suspected rAAA?
Odds Ratio: 18.2 (95% CI 5.83–56.73)
A Shock Index ≥ 1.0 is a useful prehospital and hospital predictive tool for identifying ruptured abdominal aortic aneurysms and predicting higher mortality and transfusion needs.

SI ≥1.0 was associated with rAAA confirmation and transfusion needs; leaves open prehospital triage utility pending prospective studies.
Dirks et al. (2020) conducted an observational in Suspected rupture of abdominal aortic aneurysms (rAAA) (n=313). Shock Index ≥ 1.0 vs. Shock Index < 1.0 was evaluated on Presence of a ruptured abdominal aortic aneurysm (hospital Shock Index) (OR 18.2, 95% CI 5.83-56.73). A hospital Shock Index ≥ 1.0 was strongly associated with the presence of a ruptured abdominal aortic aneurysm (OR 18.2; 95% CI 5.83-56.73) and higher in-hospital mortality (68.0% vs 39.0%).
