Brief Summary:
Point-of-care (POC) creatinine devices allow rapid measurement of creatinine levels and calculation of estimated glomerular filtration rate (eGFR) which give an indication of renal function. The focus of this assessment is to validate POC measurements to assess kidney function before intravascular iodinated contrast administration in patients with severe renal insufficiency (eGFR \< 30 ml/min/1.73m2). It will be evaluated whether discrepancies between POC measurement values and values obtained from standard laboratory assays lie within an acceptable range using Bland-Altman analysis.
Detailed Description:
Measurement of creatinine to determine eGFR before intravascular iodinated contrast administration is indicated to assess whether a patient is at risk of contrast-induced acute kidney injury (AKI). For patients with reduced eGFR intravenous hydration can be offered before the scan to reduce the risk of AKI. If no recent eGFR measurement is available, contrast procedures could be cancelled and rescheduled while a creatinine test is processed in the laboratory. Using POC creatinine tests before contrast-enhanced procedures could minimise the risk of kidney injury, and may reduce the number of cancelled scans. The question is whether POC creatinine assay is accurate and beneficial in this setting compared to the standard laboratory assay.
The i-STAT Alinity POC creatinine device is one of three devices which calculate estimated glomerular filtration rate (eGFR) recommended in clinical practice guidelines to assess kidney function to guide decisions on the use of intravascular iodinated contrast in adults. In the study, i-STAT Alinity POC measurements of creatinine will be performed using already available blood samples of patients with estimated eGFR\<30 ml/min/1.73m2 and mean difference between eGFR and serum creatinine measurements using POC and standard laboratory assays will be calculated. Results will be used to evaluate the agreement between of POC and laboratory assays on risk stratification (i.e., the percentage of patients with eGFR\<30 according to both laboratory and POC assays) and post-contrast acute kidney injury (AKI; i.e., the percentage of patients with post-contrast acute kidney injury according to both laboratory and POC assays). Finally, the number of elective procedures which are delayed (including delayed planning) or cancelled because a serum creatinine assay is required and unavailable will be prospectively evaluated for Maastricht UMC+ in this study.
