Preoperative Score to Predict Postoperative Mortality of Le Manach et al (POSPOM): Total Score

Description

Le Manach et al developed the Preoperative Score to Predict Postoperative Mortality (POSPOM). This can help to identify a patient at greater risk for in-hospital mortality after surgery. The authors are from multiple institutions in Canada, Europe and South Africa.


Patient selection: age >= 18 years undergoing surgery

 

Outcome: in-hospital mortality

 

Parameters:

(1) subscore for age and comorbid conditions

(2) subscore for the operative procedure

 

total score =

= (subscore for age and comorbidity) + (subscore for operative procedure)

 

Interpretation:

• minimum total score: 0

• maximum total score: > 60 (a score above 45 is unusual)

• The higher the score the greater the risk of in-hospital mortality.
