Wexner Score for Obstructed Defecation Syndrome (ODS)

Description

Calculates the Wexner Constipation Score (also known as the Agachan-Wexner Score) for evaluating the severity of constipation and Obstructed Defecation Syndrome. The score ranges from 0 to 30 (though often modified versions like the ODS-specific subset sum to 20 or similar, this function assumes standard item summation as per the original validation for constipation severity).

                 abdominal_pain, time_per_attempt_minutes,
                 assistance_needed_per_attempt, unsuccessful_attempts_per_24h)
