Some of frequent questions are below, but if you have any other questions about the eGFR-C study please contact the study team .

If a potential participant has a history of alcohol or drug abuse but it has stopped, are they excluded from the study?

No, if the alcohol or drug abuse is not a current problem then the patient can be included in the study.

When recording the time that the iohexol infusion is administered, what time should be used – the start or the finish?

The mid-point of the infusion should be recorded, although we will shortly add fields for recording both start and finish times on the CRF to automatically calculate the mid-point.

What should I do if our study blood pressure monitor has a problem?

The monitors are guaranteed until 17th February 2017. Before then it can be replaced – this should be arranged through Gillian Eaglestone, eGFR-C Lead Research Nurse ( geaglestone@nhs.net ).

Any operational queries can be individually telephoned or emailed to the dealer White Medical:

What is the latest time the iohexol assessments can start?

As long as the participant adheres to the guidelines on permitted food, then the iohexol assessment can be started at any time before 12pm - as long as the participant is prepared to stay until as late as 4pm.

What time should be recorded as the start of the iohexol assessment?

The mid-point of the iohexol infusion will be used as the start of the assessment. As soon as the change can be implemented, the CRFs will ask you to record the start and finish times of the iohexol infusion to calcuate the exact mid-point. Until then, please record the mid-point yourself.
