Association Between Malnutrition & Clinical Outcomes in the Intensive Care

Status Completed

Clinical Trial Summary

Previous studies have demonstrated the direct associations between malnutrition and hospital mortality as well as the length of stay in critically ill patients. However, the validity of these results may be limited by inappropriate diagnoses of malnutrition, small sample size, possible treatment bias, and sub-optimal statistical adjustment. This study aimed to further examine the aforementioned associations by addressing these limitations.

Clinical Trial Description

Design:

- Prospective cohort study

Setting:

- 35-bedded integrated intensive care/ high dependency unit in Ng Teng Fong General Hospital. Patients' status can be changed between ICU-status and HD-status within the same ICU-/ HD-bed

Participants:

- All adult patients who will be admitted to the unit between August-2015 to October-2016 for ≥ 24 hours

Intervention:

Nil. Given the observational nature of this study, no attempt will be made to standardize care, including nutritional practices.

Measurement:

- As per routine care, a validated nutritional assessment tool [7-point Subjective Global Assessment (7-point SGA)] will be used to determine patients' nutritional status within 48 hours of ICU admission

- The primary outcomes will be hospital mortality and ICU length of stay. To measure hospital mortality, all patients will be followed until hospital discharge or death for up to one year after ICU admission. For ICU length of stay (in days), duration will be measured from the date of the first ICU admission to the date of the first change in ICU-status to HD-status or discharge to the general ward

Analysis:

- Modified Cox regression model with robust variance and logistic regression will be used to determine the associations between nutritional status and hospital mortality. Analyses will be conducted in two ways: 1) presence versus absence of malnutrition, and 2) dose-dependent association for each 1-point decrease in the 7-point SGA

- Multiple linear regression will be applied to determine the associations between nutritional status and ICU length of stay ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
