2008 International Nutrition Survey: Preliminary Results ANZICS/ Au. SPEN Conference Sydney, Australia November 1, 2008
Critical Care Nutrition. Mission Statement To improve practice of nutrition therapies in the critical care setting through knowledge generation, synthesis, and translation that ultimately leads to improved clinical outcomes for critically ill patients and improved efficiencies to our health care systems. Knowledge Generation • RCTs evaluating: - Acidified EN -Small bowel feedings -Cisapride - Immunonutrition - Feeding Algorithms • REDOXS Knowledge Synthesis • Over 40 systematic reviews • Internationally recognized clinical practice guidelines Knowledge Translation • Cluster RCT of guideline implementation strategies • Ongoing international practice audits • International attitudes & beliefs survey

Achieving Best Practice: Quality Improvement What ought to be done? RCTs, Systematic Reviews, and Evidence-based practice guidelines What is done? How to change? Survey results KT Strategies What do we need to do differently? Benchmarking; Best Achievable Practice
Objectives of International Audit • To determine current nutrition practice in the adult critical care setting (overall and subgroups) • Illuminate gaps between best practice and current practice • To identify interventions to target for quality improvement initiatives • To determine factors associated with optimal provision of nutrition • To determine what nutrition practices are associated with best clinical outcomes
Methods • Prospective observational cohort study • Start date: 14 May 2008 • 20 consecutive critically ill patients • Data included: – Hospital and ICU demographics – Patient baseline information (e. g. age, admission diagnosis, APACHE II) – Baseline Nutrition Assessment – Daily Nutrition data (e. g. type of NS, amount NS received) – 60 day outcomes (e. g. mortality, length of stay)
Methods Eligibility Criteria • ICU Site – >5 beds – Availability of individual with knowledge of clinical nutrition to collect data • Patient – In ICU > 72 hours – Mechanically ventilated within 48 hours

Future Directions Quality Improvement Initiatives • Inadequate EN delivery – early EN feeding protocols – small bowel feeding • Optimize Pharmaconutrition – use of glutamine, antioxidants, omega-3 FFA. • Tighten glycemic control • Withhold soy bean emulsion lipids • others?
Future Directions Hypothesis–generating Observations – Protocolized vs Non protocolized – Academic vs Community – Presence of dietitian and how much? – Subgroups • by BMI • by Case Mix (Trauma, Sepsis; Pancreatitis, etc. ) – others?
