Description

Dhir et al developed a nomogram for predicting perioperative mortality following the resection of a gastric malignancy. This can help to identify a patient who may benefit from more aggressive management or an alternative treatment. The authors are from the University of Nebraska.


 

Patient selection: age >= 18 year with malignant gastric tumor

 

Parameters:

(1) age in years

(2) gender

(3) congestive heart failure (CHF)

(4) cardiac arrhythmia

(5) renal failure

(6) “other” neurologic disorders (other than paralysis)

(7) coagulopathy

(8) COPD

(9) fluid and/or electrolyte disorder

(10) procedure type

(11) elective admission

total score =

= SUM(points for all 11 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 563

• The higher the score the greater the perioperative mortality.
