Score of Gorter et al for Predicting Complex Appendicitis

Description

Gorter et al developed a score for predicting complex appendicitis in children. The authors are from Emma Children's Hospital AMC & VU University Medical Center Amsterdam, Red Cross Hospital in Beverwijk, IJsselland Hospital in Capelle and the Academic Medical Centre Amsterdam in The Netherlands.

Patient selection: child with acute appendicitis

Parameters:

(1) temperature in °C

(2) duration of abdominal pain in days

(3) signs of complex appendicitis on ultrasound (free fluid, abscess, contained phlegmon, distended bowel)

(4) diffuse abdominal guarding

(5) C-reactive protein (CRP) in mg/L

Parameter	Finding	Points
temperature in °C	<= 37.5 °C	0
	> 37.5°C	1
duration of abdominal pain	<= 1 day	0
	> 1 day	2
signs of complex appendicitis	absent	0
	present	2
diffuse abdominal guarding	absent	0
	present	3
CRP	<= 38 mg/L	0
	> 38 mg/L	2

total score =

= SUM(points for all 5 parameters)

Interpretation:

• minimum score: 0

• maximum score: 10

• A score >= 4 was associated with complex appendicitis.

Performance in the derivation set:

• The sensitivity was 89% and specificity 88%.

• The area under the ROC curve was 0.91.
