Early Prediction for Prognosis of Colorectal Perforation (EPPoC) Score of Matsuoka et al

Description

Matsuoka et al reported a score for predicting short-term mortality for a patient undergoing surgery for colorectal perforation based on perioperative factors. This score can help to identify a patient who may benefit from more aggressive management. The authors are from Saiseikai Utsunomiya Hospital, Keio University and Jichi Medical University in Japan.

Patient selection: colorectal perforation

Outcome: in-hospital and 30-day mortality

Parameters:

(1) hemodialysis

(2) percent reduction in platelet count (time of diagnosis vs immediate post-operative)

(3) age in years

(4) cause for perforation

(5) serum albumin in g/dL

percent change in platelet count =

= ((count at diagnosis) - (count after surgery)) / (count at diagnosis) * 100%

Parameter	Finding	Points
hemodialysis	no	0
	yes	3
percent reduction in platelet count	< 25%	0
	>= 25%	3
age in years	< 75 years	0
	>= 75 years	2
cause of perforation	diverticulitis	0
	colon cancer	0
	other (ischemia, fecal impaction)	1
serum albumin	> 2.5 g/dL	0
	<= 2.5 g/dL	1

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 10

• A score >= 5 was associated with a risk of mortality >= 25%.

Performance:

• The area under the ROC curve is 0.89.

• The area under the ROC curve for major postoperative complications was 0.78.
