The Boston Bowel Preparation Scale is a commonly used scale to assess the efficacy of bowel preparation prior to colonoscopy. It evaluates the clarity of the liquid contents, presence of solid material, and adequacy of mucosal visualization on a 0-3 point scale. A score of 0 indicates clear liquid without solid material and excellent mucosal visualization, while a score of 3 represents opaque liquid with abundant solid material and poor mucosal visualization.
