Masoomi et al identified a number of factors predictive of in-hospital mortality following colorectal surgery. These can help to identify patients who may benefit from more aggressive management. The authors are from the University of California at Irvine.


Patient selection: adult undergoing colorectal surgery


Risk factors with an odds ratio from 2.4 to 3.5:

(1) emergency surgery

(2) liver disease

(3) age > 65 years

(4) total colectomy

(5) chronic renal failure


Risk factors with an odds ratio from 1.8 to 2.0):

(1) malignant tumor

(2) open operation (vs laparoscopic)

(3) peripheral vascular disease

(4) diverticulitis


The more risk factors that are present the greater the risk of in-hospital mortality.


Factors associated with reduced mortality (odds rato 0.44 to 0.59):

(1) smoking

(2) proctectomy

(3) Crohn’s disease
