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 solution (480 mL) provides effective bowel preparation with significantly less volume than traditional PEG solutions, though taste acceptability remains a challenge due to its distinctive bitter flavor
• Patient characteristics may predict preference for low-volume OSS preparations, enabling nurses to provide more personalized pre-procedure counseling and preparation selection
• Understanding patient factors associated with OSS tolerance can help nurses better prepare patients for what to expect and provide targeted education to improve compliance
• Both OSS and PEG-ASC demonstrated comparable cleansing efficacy, giving nurses evidence-based options when discussing bowel preparation choices with patients and providers

Clinical Relevance

This research directly impacts pre-procedure patient education and counseling protocols in endoscopy units. As GI nurses frequently serve as the primary point of contact for bowel preparation instructions, understanding which patients may prefer or tolerate OSS solutions enables more individualized care. The identification of specific patient characteristics associated with OSS preference provides nurses with clinical indicators to guide preparation selection discussions with both patients and gastroenterologists. This personalized approach can potentially improve patient compliance and satisfaction while maintaining optimal cleansing outcomes.

From an operational standpoint, having evidence-based data on patient factors that predict OSS preference can streamline the preparation selection process and reduce last-minute preparation changes due to poor tolerance. Nurses can use these findings to develop more targeted patient education materials and counseling approaches, particularly focusing on taste expectations and volume benefits for appropriate patient populations. Additionally, this information supports quality improvement initiatives aimed at optimizing patient experience while maintaining the clinical standards necessary for successful colonoscopy completion.

The comparable efficacy between OSS and PEG-ASC preparations reinforces that nurses can confidently support either option based on patient-specific factors rather than concerns about cleaning effectiveness. This flexibility is particularly valuable in busy endoscopy practices where patient preferences and tolerance issues can significantly impact procedure scheduling and completion rates.

Bottom Line

This study provides GI nurses with evidence that 480-mL oral sodium sulfate offers effective bowel cleansing comparable to larger-volume PEG preparations, and identifies patient characteristics that may predict OSS preference, enabling nurses to provide more personalized pre-procedure counseling that balances the benefits of lower volume against taste considerations to optimize both patient satisfaction and preparation success.
