Tursi et al reported the Diverticular Inflammation and Complications Assessment (DICA) for evaluating a patient with diverticulosis. The authors are from multiple institutions from around the world.
Patient selection: diverticulosis/diverticulitis
Examination: colonoscopy
Parameters:
(1) diverticulosis extension
(2) number of diverticular in each district
(3) signs of inflammation
(6) rigidity of colon
(7) stenosis of the colon
(8) pus
(9) bleeding

where:
• Scoring is ambiguous. It is unclear if both left and right are scored separately. The number of diverticuli is "per district" but district is undefined. The others are assumed to be scored once.
• Scoring of inflammation is based on Methods in Tursi et al (2019).
total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 1
• maximum score: 19 (for table above)
• The higher the score the more severe the diverticular disease.
