International Critical Care Nutrition Survey 2008 Defining Gaps in Practice Rupinder Dhaliwal, RD Project Leader Critical Care Nutrition, Clinical Evaluation Research Unit Kingston, Ontario, Canada
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 Knowledge Synthesis Knowledge Translation www.criticalcarenutrition.com
History of International Surveys 3 previous surveys in Canada 2001, 2003, 2004 N > 50 ICUs each year Extended to other countries in 2007 Focus on North America n=165 Repeated in 2008 Focus on Australasia
Objectives of International Survey To determine current nutrition practice in the adult critical care setting Illuminate gaps between best practice and current practice To identify interventions to target for quality improvement initiatives To determine what nutrition practices are associated with best clinical outcomes To determine factors associated with optimal provision of nutrition
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 hospital outcomes (e.g. mortality, length of stay)
Methods Eligibility Criteria ICU Site Patient >8 beds Availability of individual with knowledge of clinical nutrition to collect data Patient In ICU > 72 hours Mechanically ventilated within 48 hours

Strategies to Optimize EN Delivery: Feeding Protocol Characteristics Total n=157 Feeding Protocol Yes 125 (79.6%) Gastric Residual Volume Tolerated in Protocol Mean (range) 208 (100, 500) Algorithms included in Protocol Motility agents 83 (71.6%) Small bowel feeding 61 (52.6%) Withholding for procedures 57 (49.1%) HOB Elevation 93 (80.2%) Other 22 (19.0%)

638/2368 (26.9%) EVER had EN interrupted due to intolerance* Feeding Intolerance 638/2368 (26.9%) EVER had EN interrupted due to intolerance* 1399/17,438 (8.0%) patients days had EN interrupted due to intolerance This second number seems really low, please check * Presence of high gastric residual volumes / emesis / aspiration
Strategies to Optimize EN Delivery: Motility Agents
Strategies to Optimize EN Delivery: Small Bowel Feeding
% of patients received small bowel feeding before PN started EN in Combination with PN % of patients received small bowel feeding before PN started
Strategies to Optimize EN Delivery: Head of Bed Elevation
Use of Pharmaconutrients Total % Patients Ever on EN receiving formula Arginine-supplemented formulas 6.0%(0.0%-93.8%) Glutamine supplementation 7.6%(0.0%-88.9%) Fish oil enriched formula (All) 3.1% (0.0%-83.3%) Fish oil enriched (ARDS) 10.5% (0.0%-88.9%) Polymeric 90.5% (0.0%-100.0%) Please double check data
Strategies to Optimize PN Delivery: Use of IV Glutamine Use of PN glutamine in Patients receiving PN
Intensive Insulin Therapy In all critically ill patients, we recommend avoiding hyperglycemia (blood glucose > 10 mmol/l)
