Impairment Rating for an Anal Disorder

Purpose: To determine the level of physical impairment associated with an anal disorder based on the rating scale of Baik et al.

Baik et al listed criteria for rating impairment in a patient with an anal disorder. This was one several rating systems developed by the Korean Academy of Medical Sciences.


Disorder

Percent Physical Impairment

severe constipation requiring periodic enema or colonic irrigation, OR perineal descent syndrome causing continuous anal pain and/or constipation

0 to 9%

intermittent fecal incontinence of gas or liquid stool

10 to 19%

chronic anal fistula OR intermittent fecal incontinence of formed stool requiring continual treatment

20 to 35%

continuous fecal incontinence of formed stool associated with a disorder of the anal sphincter muscles
