Dear Dr Arora,
This results for this patient have reviewed as part of our departments system for monitoring chronic kidney disease
using cumulative graphs of eGFR. Based on our criteria, agreed with the renal medicine department, this patient has
been identified as at increased risk of progression to end-stage kidney disease.
If you requirefurther advice or information for the management of this patient please contact Dr Hugh Rayner at
Birmingham Heartlands Hospital.
Email [email protected] for a copy of 'CKD Made Easy'.
Please quote this patient's NHS number.
GP feedback (n=36)
• 30% usually looked at only the last few results
• 74% found the graphical eGFR report useful
• 41% had changed patient management in response to the report
• Average ease of use of the graphs = 8 out of 10 (10 = easiest)
GP feedback
“I would be grateful for your advice regarding
the above 91 year old lady.
My query is in regards to her deteriorating eGFR
which has been made clear by a graph that had
been sent to me.”
