The aim of this study is to evaluate the effects of using the GUSS-ICU Safe Nutrition Program after extubation in Intensive Care Unit patients. This randomized controlled trial will be conducted in the Anesthesia Intensive Care Unit of Bakırköy Dr. Sadi Konuk Training and Research Hospital. Eligible participants will be randomly assigned to either the control group (usual care/routine follow-up group) or the intervention group (GUSS-ICU patients). Patients undergoing GUSS-ICU assessment will continue the nutritional program, as directed by the scale, for four days. Data are recorded on the first and last day. The data will then be evaluated in conjunction with the control group data.

The aim of this study is to evaluate the effects of using the GUSS-ICU Safe Nutrition Program after extubation in intensive care patients. This randomized controlled trial will be conducted in the Anesthesia Intensive Care Unit of Bakırköy Dr. Sadi Konuk Training and Research Hospital. Patients who meet the criteria will be randomized into either an intervention group or a control group. Patients in the control group will receive routine post-extubation care, follow-up, and a nutrition plan. On day 1, baseline data will be collected using the m-NUTRIC score, APACHE-II, SOFA, Charlson Comorbidity Index (CCI), Scored Patient-Generated Subjective Global Assessment (PG-SGA), and a patient data form. Routine follow-up and nutrition plans will be continued. At the end of day 4, the m-NUTRIC score, APACHE-II, SOFA, Charlson Comorbidity Index (CCI), Scored Patient-Generated Subjective Global Assessment (PG-SGA), and a patient data form will be completed. Patients in the intervention group undergo a GUSS-ICU assessment within the first 4 hours after extubation. Nutrition planning is based on the assessment scores. On day 1, baseline data includes the m-NUTRIC score, APACHE-II, SOFA, Charlson Comorbidity Index (CCI), Scored Patient-Generated Subjective Global Assessment (PG-SGA), and a patient data form. Nutritional monitoring and follow-up are continued for 4 days. At the end of day 4, the m-NUTRIC score, APACHE-II, SOFA, Charlson Comorbidity Index (CCI), Scored Patient-Generated Subjective Global Assessment (PG-SGA), and a patient data form are completed. The data will then be evaluated in conjunction with the control group data.
