Clinical Scorecard: Selective Decontamination of the Digestive Tract (SDD) in Intensive Care: Legacy of Dr. Rick van Saene

At a Glance

Key Highlights

• SDD is a four-component intervention designed to prevent infections by selectively decontaminating the digestive tract.
• Over 45 years, SDD has been extensively researched with 73 randomized controlled trials and 16 meta-analyses supporting its efficacy and safety.
• SDD is included in the 2026 Surviving Sepsis Campaign international guidelines for sepsis and septic shock management.

Guideline-Based Recommendations

Diagnosis

• Identify critically ill patients at high risk of infection, particularly those with multiple trauma or sepsis.

Management

• Implement the four-component SDD strategy to control infections and reduce mortality in ICU patients.
• Incorporate SDD as part of standard care in intensive care units as recommended by the 2026 Surviving Sepsis Campaign guidelines.

Monitoring & Follow-up

• Track infection rates and patient outcomes to assess the effectiveness of SDD implementation.
• Critically evaluate emerging studies and meta-analyses related to SDD to ensure ongoing efficacy and safety.

Risks

• Be aware of initial controversies and opposition from traditional microbiology perspectives.
• Monitor for potential microbial resistance or unintended consequences, although studies support SDD safety.

Patient & Prescribing Data

Critically ill ICU patients, including those with multiple trauma and sepsis.

SDD has demonstrated a significant reduction in infection rates and mortality, supported by extensive randomized trials and meta-analyses.

Clinical Best Practices

• Adopt a multidisciplinary approach involving microbiologists and intensive care specialists for SDD implementation.
• Maintain rigorous scientific scrutiny and critical appraisal of all studies related to SDD.
• Educate and train ICU staff on the principles and application of the SDD strategy.
• Encourage ongoing research and collaboration to optimize SDD protocols and patient outcomes.
