Background and study aims
Computerised Tomography (CT) is a radiology test which takes cross-sectional images of the body using radiation (x-rays) and is vital for diagnosing (or excluding) cancer. To improve the visibility of internal organs and structures on these scans, an x-ray dye is injected into the bloodstream. This x-ray dye is commonly referred to as contrast media. In patients with reduced kidney function, the use of contrast media can cause complications. Guidelines published by the Royal College of Radiologists (RCR) recommend a blood test to measure kidney function should be available from the preceding three months for all patients referred for CT scans including contrast. There are a variety of pathways to ensure that a blood test is performed before the scan, some of which may delay imaging. The blood test allows patients with reduced kidney function to be identified, as there is a risk of Contrast Induced Acute Kidney Injury (CI-AKI). As the waiting time for imaging tests are reduced, it is important to identify how services can be streamlined. A national survey undertaken by the research team has demonstrated diversity in the current service delivery pathways for obtaining kidney function prior to cross-sectional imaging across the UK. A small number of sites offer point of care testing (PoCT) for kidney function in patients who have not had a recent blood test. However, the potential impact of their application is unknown. The aim of this study is to evaluate whether PoCT devices for determining kidney function levels can be used to streamline the patient pathway.
Who can participate?
Adult patients who are attending an appointment for a contrast-enhanced CT scan
What does the study involve?
When participants attend for their CT appointment they have an additional blood sample taken. The sample is then analysed using the PoCT device and is also sent to the lab so it can undergo standard testing to assess participant’s kidney function. Participants are asked to return for another study visit 2-3 days later for a follow up blood test which is analysed the same way.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating.

| Scientific title | Streamlining cross-sectional imaging pathways (SCIPs): A feasibility and economic modelling study of point of care creatinine testing in radiology |
| Study acronym | SCIPs |
| Study objectives | The aim of this study is to assess the feasibility of using a point of care blood test (PoCT) performed in radiology rather than the standard laboratory test. |
| Ethics approval(s) | Sheffield Research Ethics Committee, 09/01/2017, ref: 16/YH/0520 |
| Health condition(s) or problem(s) studied | Specialty: Renal disorders, Primary sub-specialty: Renal disorders; UKCRC code/ Disease: Renal and Urogenital/ Renal failure |
| Intervention | The intervention is a PoC creatinine test and a standard laboratory renal function blood test performed at the initial visit (CT scan appointment), this will take 5 minutes. This whole blood sample is processed on the point of care device according to manufacturer’s recommendations. The standard care blood sample is analysed in the laboratory on a Roche Cobas 8000 series, using an enzymatic creatinine method, according to standard operating procedures. Participants will be asked to return at 2-3 days post-contrast administration for a follow up blood test to be analysed on both the PoC device and in the laboratory. |

| Phase | |
| Drug / device / biological / vaccine name(s) | |
| Primary outcome measure | Renal function concordance measured as the difference between the serum creatinine value from PoCT and laboratory analysis at initial visit. |
| Secondary outcome measures | 1. Recruitment rate recorded as the number of eligible participants who consented to participate in the study at initial visit 2. Attrition rate recorded as the number of participants that return for follow up blood test at 2-3 days post-contrast administration 3. Failure rate recorded as the number of test analyses which do not produce a result from PoC and laboratory tests at initial and follow up visits 4. Screening questionnaire effectiveness measured as the number of patients with no risk factors who have a reduced renal function identified (eGFR <40) at initial visit 5. Renal function recorded as the concordance between serum creatinine and eGFR from the pre-scan result obtained within 3 months of scan and the renal function at initial visit 6. Rate of contrast-induced acute kidney injury (CI-AKI) recorded as the number of participants who have a ≥25% rise in serum creatinine on follow up blood test 2-3 days post-contrast administration |
