Micronutrient Levels and Nutritional Status in Critical Illness
- Conditions

- Registration Number
- NCT06119711
- Lead Sponsor
- Medical Centre Leeuwarden
- Brief Summary
Rationale: A significant proportion of patients admitted to the Intensive Care Unit (ICU) is unable to fully recover, even when the initial cause of their illness has been treated. Inadequate dietary intake prior to admission and during the recovery phase may leave patients in a frail physical state, limiting rehabilitation potential. Commonly used methods to assess nutritional intake and nutritional status are highly impacted by various disease-related confounders and reporting bias. We hypothesise that a combined assessment of biomarkers in plasma and urine may provide a more accurate overview of nutritional status at ICU-admission.
Objective:
Main: Assess nutrition-related biomarkers in plasma and urine samples at ICU admission
Secondary:
Identify the number of micronutrient deficiencies at ICU admission Compare biomarker profile and dietary intake of short and long-stay ICU patients at baseline Compare subjective dietary intake, nutritional status and muscle thickness between patients with and without micronutrient deficiencies at baseline Study design: Observational study
Study population: Adult patients admitted to the ICU. Two groups will be recruited: patients with a short length of stay (\<48 hours) and patients with a longer length of stay (≥48 hours).
Main study parameters: Biomarker status in blood and urine at ICU admission.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: In addition to standard care ICU treatment, the following measurements will be performed:
* Within 24 hours after admission blood and urine samples will be collected from existing venous line and urinary catheter
* Within 72 hours an ultrasound measurement of the upper leg will be performed.
* During ICU stay, when the patient is capable to do so, they will be asked to complete a retrospective dietary intake assessment.
The risks and negative effects of these tests are limited. However, this study asks for a time investment and physical and mental effort of the patients.
