Official title
More Than a Number: Why Daily Fluid Balance Alone Should Not Guide Clinical Decision-Making in the ICU: A Prospective Observational Study
Overview
Daily Fluid Balance vs Weight Change
Detailed description
The daily fluid balance will be compared to 24hour weight change in critical care patients. The design will be prospective observational study. The data will be gathered using Linet automatic built in weight in Linet beds and for fluid balance will be used standard nurse charting method. The main outcome will be limit of agreement between daily fluid change and 24hour weight change.
Interventions
- Other Daily Weight and fluid balance change
In all enrolled patients, both 24-hour body weight change and cumulative 24-hour net fluid balance will be assessed over identical 24-hour intervals by nursing personnel. Fluid balance will be recorded using a standardized 24-hour fluid balance chart and calculated as the difference between total fluid intake and urine output and fluid output to drains. Body weight measurement will be performed once daily. Body weight will be measured using the integrated weighing system of the ICU bed.
Primary outcome measures
- Agreement between 24hour fluid balance and daily weight change [Time frame: 24 hours from enrollment]
