Course Evaluation Survey

DIGEST: Optimizing GI Function and Nutrition in Critical Care is a comprehensive, practice-focused course designed to help clinicians confidently assess, initiate, and optimize nutrition in critically ill patients with gastrointestinal dysfunction. From differentiating functional ileus vs. mechanical obstruction to selecting the safest feeding route and monitoring tolerance, you’ll learn a stepwise, evidence-informed approach that translates directly to bedside decisions. The curriculum follows a clear DETERMINE–INITIATE–GIVE–EVALUATE–SUPPORT framework, guiding you from risk stratification and timing of feeds to calculating requirements, preventing complications, and tailoring pharmacologic support. You’ll master how to build decision matrices for when and what to feed, set up enteral and parenteral nutrition plans, place and maintain feeding tubes, and respond to intolerance using clinical signs, GRV trends, and POCUS insights. Engaging elements—including an interactive Pixel Quest scenario—reinforce core concepts and sharpen clinical reasoning. By course end, you’ll be equipped with protocols, checklists, and calculation shortcuts to streamline care, reduce complications, and improve outcomes for complex GI patients. Ideal for high-acuity settings, this course empowers you to protect the gut, preserve lean mass, and transition safely to voluntary intake with confidence.

            <p>Critical illness frequently precipitates complex gastrointestinal dysfunction, necessitating a sophisticated approach to assessment and risk stratification. This course, DIGEST: Optimizing GI Function and Nutrition in Critical Care, provides a comprehensive framework for analyzing the physiological mechanisms that predispose patients to functional ileus, mechanical obstruction, and gastroparesis. By identifying specific physiological markers and clinical signs of feeding intolerance, veterinary professionals can better determine the duration of acceptable anorexia and recognize the critical threshold for immediate nutritional intervention. Understanding the impact of prolonged fasting in hypermetabolic states is essential for mitigating the risks associated with malnutrition and ensuring the preservation of enterocyte health during acute illness.</p>

<p>Beyond initial assessment, the curriculum delves into the strategic development and implementation of nutritional plans tailored to the specific needs of the critically ill patient. Participants will explore the nuances of diet selection, Resting Energy Requirement (RER) calculations, and the mitigation of refeeding syndrome. The course further examines the technical aspects of route selection—comparing enteral and parenteral options—and provides detailed guidance on the placement and maintenance of various feeding tubes, from nasogastric to jejunostomy. Advanced monitoring techniques, including the use of Point of Care Ultrasound (POCUS) to evaluate gastric emptying and the interpretation of Gastric Residual Volume (GRV) trends, are emphasized to ensure tolerance. Finally, the integration of pharmacological support and systematic tracking of fecal output and weight gain will equip clinicians with the tools necessary to transition patients from assisted feeding to voluntary intake successfully.</p>
