Education program on medical nutrition and length of stay of critically ill patients

Background & aims: To evaluate the impact of a multifaceted nutritional educational intervention on the quality of nutritional therapy and clinical outcomes in critically ill patients. Methods: We conducted a prospective, non-blinded study with a non-contemporaneous control group at a 16-bed intensive care unit (ICU) at the Hospital das Clinicas, Department of Gastroenterology, University of Sao Paulo Medical School in Sao Paulo, Brazil. There were three phases. Phase 1: the quality of NT was evaluated in 50 newly admitted intensive care unit patients in a pre-educational program (Pre-EP). Phase 2: nutritional protocols were created and an education program was implemented. Phase 3: another 50 patients were enrolled and observed in a post-educational program (Post-EP) using phase 1 methodology. Nutritional Therapy practice was evaluated through nutritional assessments, adequacy of energy requirements, duration of fasting, and use of early enteral nutrition. Intensive care unit length of stay and hospital length of stay were measured as primary end-points. Results: The pre-educational program and post-educational program groups did not differ in age, APACHE II score, gender, or nutritional assessment. The mean +/- SD duration of fasting decreased (Pre-EP 3.8 +/- 3.1 days vs. Post-EP: 2.2 +/- 2.6 days; p = 0.002), the adequacy of nutritional therapy improved (Pre-EP 74.2% +/- 33.3% vs. Post-EP 96.2% +/- 23.8%; p < 0.001), and enteral nutrition was initiated earlier than 48 h more commonly (Pre-EP 24% vs. Post-E 60%; p = 0.001). Median intensive care unit length of stay decreased (Pre-EP: 18.5 days vs. Post-EP: 9.5 days; p < 0.001) although hospital length of stay did not. Conclusion: Implementing a multifaceted nutritional educational intervention could improve the quality of nutritional therapy and may decrease intensive care unit length of stay in critically ill patients.
