1) To determine the adequacy energy and protein of patients intake with a seven day or more stay in the Intensive Care Unit comparing the effect of referral to the clinical nutrition team and without referral to the team.
2.) To show the mortality, changes in selected laboratory data, number of ventilator days, length of stay in the Intensive Care Unit, and length of hospital stay of these patients in relation to adequacy or inadequacy of energy and protein intake.


Design: retrospective cohort study
Participants: 1.) Adults ([>/=]18 years old and above) admitted in the Medical Intensive Care Unit of St. Luke's Medical Center Quezon City from January 2011 to June of 2012. 2.) Patient admitted in the Intensive Care Unit with an average stay of 7 days. 3.) Patients on enteral nutrition, parenteral nutrition or a combination of both feeding during the course of ICU stay.


Patients referred to the nutrition team were able to attained 76% of the calorie requirement and 77% of the protein requirement as compared to the non referred patients who consumed 61 % of the calorie requirements and 62% of the protein requirements. Based on statistical analysis using Chi-square, there is no significant difference between adequacy of calorie intake p=0.152 and adequacy of protein intake p=0.357. For the selected laboratory data, there is a significant decrease in WBC, TLC, platelet and creatinine among referred patients. For the length of mechanical ventilation and ICU stay, patients who are alive and adequately fed have longer mechanical ventilation and ICU days as compared to the inadequately fed alive patients, with the P<0.001. For the length of hospital stay, patients who are adequately fed and alive stayed longer in the hospital as compared to the inadequately fed counter parts with the P=0.002 using the statistical analysis Mann-Whitney U test.


Patients referred to the nutrition team have higher intake adequacy. They have better laboratory results, longer mechanical ventilation days, longer ICU days and longer length of hospital stay. This is because patients with inadequate intake tend to die early and discharged earlier than their adequately fed counterparts.
