IMP-ICDX: an injury mortality prediction based on ICD-10-CM codes

Table 3 Model performance: anatomic injury models augmented with age, gender, and injury mechanism

Model description	AUC (95% CI)	H-L stat (95% CI)	AIC
ISS	0.903 (0.899–0.908)	152 (106–202)	25,916
Single worst injury	0.915 (0.910–0.919)	37.4 (18.3–52)	21,970
IMP-ICDX	0.919 (0.914–0.923)	26.5 (11.2–41)	21,660

Although every model will be changed by the addition of more predictors, IMP-ICDX still shows superior model compared to the SWI and ISS models
