Description of intervention(s) / exposure
Enrolled patients will have 5ml of urine taken from the in situ catheter and analyzed on the point-of-care analyzer and sent for labratory analysis at SA pathology. Urine samples will be taken by a trained clinical researcher, whom is also trained and efficient with the point-of-care analyser being used.

Outcomes
Primary outcome [1] 304860 0
The primary outcome is measurement of agreement between the POC analyser and laboratory analysis of albumin/creatinine measurements,

Agreement between measures will be analysed by Lin’s concordance correlation coefficient with Bland-Altman plots including 95% confidence limits of agreement. References 1 and 2.

Timepoint [1] 304860 0
The timepoint of the primary outcome is the time at which a urine sample is taken for albumin/creatinine analysis.
Secondary outcome [1] 343397 0
The secondary outcome is a composite outcome to determine feasibility of using the POC analyser for routine use in the ICU setting. This will be determined by time efficiency and frequency of errors. Time efficiency will be calculated by reporting the time from urine sample acquisition to the POC result read out and by reporting the time from sending the urine sample to the central laboratory to time of reporting. The frequency of errors will be determined by the occurrence of errors resulting in no result readout. These errors are displayed as specific codes referring to a potential cause on the analyser screen.
Timepoint [1] 343397 0
At time of albumin/creatinine analysis following patient admission to ICU.

Summary
Brief summary
Serum/plasma (blood) is routinely used for measurement of albumin/creatinine in the critically ill. However, point-of-care (POC) urinary albumin/creatinine testing in patients admitted to the Intensive Care Unit (ICU) may be advantageous due to the rapid availability of results. To date, the accuracy of POC urinary albumin/creatinine compared to laboratory analysis in this population has not been evaluated. The anticipated outcome of this project is that if agreement is detected between POC and laboratory analysis, then POC testing may be a valuable methodology for measuring urinary albumin/creatinine in critically ill patients. This could have useful applicability for rapid assessment of results, therefore predicting prognosis and mortality in this population.
