Prognostic Model of Dupont et al for a Critically Ill Patient with Candida Peritonitis

Purpose: To evaluate a critically ill patient with Candida peritonitis using the prognostic model of Dupont et al.

Description

Dupont et al identified risk factors associated with mortality in critically ill patients who develop polymicrobial peritonitis containing a Candida species. This can help identify patients who may require more aggressive management. The authors are from University Hospital Bichat-Claude Bernard in Paris.


Parameters identified on multivariate analysis:

(1) APACHE II score

(2) respiratory failure

(3) source

(4) direct smear of peritoneal fluid

• A source cephalad to the mesocolon (stomach, duodenum, biliary tract) was considered upper gastrointestinal, else lower.

 

X =

probability of death =

= 1 / (1 + EXP((-1) * X))
