Chief complaints associated with mortality involving civilian transport after Wen-chuan earthquake

Abstract

Objectives 

Previous studies have reported that civilian transport is a mortality risk factor in low-resource communities. Few studies have analyzed the chief complaints associated with mortality involving civilian transport after an earthquake.

Therefore, the present study was conducted to determine whether mortality resulting from medical professional transport differs from that involving civilian transport, and if so, the chief complaints associated with mortality involving civilian transport after the Wen-chuan earthquake.

Methods 

A hospital-based case–control study was conducted. Cases included all victims transported by civilians to West China Hospital from the disaster area (n=473). Controls included all victims transported by medical professionals to West China Hospital (n=1452). We further analyze six potential chief complaints of death to clarify the specific contributing chief complaints associated with mortality involving civilian transport.

Results 

Civilian transport is associated with significantly greater mortality compared with medical professional transport (Pearson’s χ²-test: P<0.05). Patients with altered mental status had the greatest risk of death [odds ratio (OR)=4.552, 95% confidence interval (CI)=2.165–9.572], followed by patients with trunk injury (OR=2.517, 95% CI=1.251–5.066), and finally patients with shortness of breath (OR=2.345, 95% CI=1.040–5.288).

Conclusion 

Altered mental status, trunk injury, and shortness of breath were the significant chief complaints associated with mortality involving civilian transport to the hospital after the Wen-chuan earthquake. Our data suggest that patients with any of these complaints should be transported by medical professionals, not civilians, to the nearest hospital for treatment.
