Patient Characteristics Associated With Preference for 480-mL Oral Sodium Sulfate: A Prospective Clinical Study on Bowel Cleansing Efficacy and Taste Acceptability for Total Colonoscopy.

Key Takeaways for GI Nurses

• Oral sodium sulfate solutions (OSS) provide effective low-volume bowel preparation but present taste acceptability challenges due to their distinctive bitter flavor that may impact patient compliance
• Patient-specific factors influence preference for 480-mL oral sodium sulfate versus traditional polyethylene glycol plus ascorbate (PEG-ASC) preparations, requiring individualized assessment during pre-procedure education
• Understanding which patients are more likely to tolerate OSS can help nurses optimize bowel preparation selection and improve patient satisfaction while maintaining cleansing efficacy
• Both preparation types demonstrate comparable bowel cleansing effectiveness, allowing flexibility in choosing the most appropriate option based on patient characteristics and preferences

Clinical Relevance

This research directly impacts pre-procedure nursing assessment and patient education protocols in endoscopy units. As frontline educators, GI nurses play a crucial role in bowel preparation selection and patient counseling. Understanding that certain patient characteristics predict better tolerance of low-volume OSS preparations enables nurses to make more informed recommendations during pre-colonoscopy consultations. This knowledge can reduce preparation failures, improve patient compliance, and ultimately decrease the need for repeat procedures due to inadequate bowel cleansing.

The findings also have significant implications for unit workflow and patient satisfaction scores. When nurses can accurately identify patients who are good candidates for OSS based on specific characteristics, they can proactively address taste concerns and provide targeted support strategies. This personalized approach may reduce last-minute preparation changes, decrease patient anxiety, and improve overall procedural outcomes. Additionally, having evidence-based criteria for preparation selection supports nursing documentation and helps justify clinical decisions to patients, families, and physicians.

From a quality improvement perspective, this research provides valuable data for developing standardized protocols and decision-making tools. Endoscopy units can incorporate these patient characteristic guidelines into their pre-procedure assessment forms and nursing documentation systems, creating a more systematic approach to bowel preparation selection that optimizes both efficacy and patient experience.

Bottom Line

While oral sodium sulfate offers an effective low-volume alternative to traditional PEG-based preparations, its bitter taste remains a significant barrier that requires careful patient selection and targeted nursing intervention. GI nurses should use identified patient characteristics to guide preparation recommendations and provide enhanced support for patients receiving OSS, ensuring optimal cleansing results while minimizing tolerance issues that could compromise procedural success.
