Introduction: Enteral feed is an important component of nutritional therapy in critically ill patients and underfeeding has been associated with adverse outcomes. The article developed an enteral feeding protocol and planed a before-and-after comparative trial to explore whether implementation of enteral feeding protocol was able to improve clinical outcomes.
Methods and analysis: The study will be conducted in intensive care units (ICUs) of ten tertiary care academic centers. Critically ill patients expected to stay in ICU for over 3 days and require enteral nutrition (EN) were potentially eligible. This is a before-and-after study comprising three phases: The first phase is the period without enteral feeding protocol; the second phase involves four-week training program, and the last phase is to perform the protocol in participating centers. We plan to enroll a total of 350 patients to provide an 80% power and 0.05 error rate to detect a 15% reduction of mortality. The primary outcome is 28-day mortality.
Ethics and dissemination: Ethical approval to conduct the research has been obtained from all participating centers. Additionally, the results will be published in peer-reviewed journal.
Trial registration: The study was registered at International Standard Registered Clinical/soCial sTudy Number (ISRCTN) registry (ISRCTN10583582).
