Risk Factors of Kadri et al for In-Hospital Mortality for a Patient with Smoke Inhalation and Acute Lung Injury (ALI)

Patient selection: adult (age >= 18 years) burn patient with smoke inhalation and acute lung injury (ALI, ICD-9 508.2)

Risk factors for in-hospital mortality:

(1) age > 60 years

(2) >= 20% total body surface area burned

(3) initial vasopressor use

(4) DRG-based risk of mortality extreme (based on the 3M APR-DRG admission risk of mortality classification scale from minor to extreme)

(5) lower hospital bed capacity (< 500 beds)

where:

• Burn center status was not significant in the analysis. This could have an interaction with hospital bed capacity.

A model developed on these 5 risk factors performed better than a model based on age and burn surface area alone.
