Manning Criteria for Diagnosis of Irritable Bowel Syndrome (IBS)

Description

Calculates the Manning Score to estimate the likelihood of Irritable Bowel Syndrome (IBS). The score counts the number of positive symptoms out of six specific gastrointestinal complaints. Higher scores correlate with a higher specificity for IBS.

Usage

manning_ibs_criteria(pain_relieved_by_defecation, incomplete_bowel_movement,
                     mucus_in_stool, change_in_stool_consistency,
                     more_frequent_stool_with_pain, abdominal_distension)

Arguments

pain_relieved_by_defecation	Numeric (0 or 1). Abdominal pain relieved by defecation. (1 = Yes).
incomplete_bowel_movement	Numeric (0 or 1). Feeling of incomplete bowel movements. (1 = Yes).
mucus_in_stool	Numeric (0 or 1). Passage of mucus per rectum. (1 = Yes).
change_in_stool_consistency	Numeric (0 or 1). Change in stool consistency (looser stools) with onset of pain. (1 = Yes).
more_frequent_stool_with_pain	Numeric (0 or 1). More frequent bowel movements with onset of pain. (1 = Yes).
abdominal_distension	Numeric (0 or 1). Visible abdominal distension. (1 = Yes).

Value

A list containing:

Manning_Score	The total count of positive criteria (Range 0-6).
Interpretation	Diagnostic likelihood based on the number of criteria met.

Examples

# Example 1: High Likelihood
# Pain relief(1), Incomplete(1), Distension(1), Consistency(1)
# Score = 4

# Example 2: Low Likelihood
# Distension only
# Score = 1
manning_ibs_criteria(0, 0, 0, 0, 0, 1)
