Parameters:

(1) lower abdominal pain

(2) duration of history in hours

(3) pattern of pain

(4) guarding and rebound tenderness

(5) temperature

(6) pulse rate

(7) WBC count

clinical scoring index =

= SUM(points for all 7 parameters)

 

Interpretation:

• minimum index: 0

• maximum index: 7

• A score <= 2 was seen with acute appendicitis without perforation or gangrene.

• A score >= 3 was seen with perforation or gangrenous appendicitis.

 

Performance:

• The diagnostic accuracy was 89%.
