RRID Study

In October and December 2015, Professor Maarten Taal, Consultant Nephrologist at Derby Teaching Hospitals NHS Foundation Trust (DHFT), hosted a series of patient feedback events at Pride Park in Derby to discuss the progress so far of the RRID study (Renal Risk In Derby).  

RRID is one of the largest single centre studies in the country and is led by Professor Taal, with support from Research Fellow, Dr Adam Shardlow and he has  also had assistance from a  team of very dedicated research staff.  The trial has been running since 2008 and has seen 1741 patients recruited to it. Although he did not see all the patients at the start of the study, Dr Shardlow has interviewed 1059 of the patients at the recent 5 year follow up stage so the feedback event was somewhat of a ‘reunion’ for him.


Aim of study

Describe patients with CKD stage 3 in   Primary Care and their treatment needs

Investigate risk factors for CKD progression

Investigate risk factors and mechanisms leading to increased heart and blood vessel problems

Develop risk prediction scores for kidney and heart/blood vessel outcomes


The story so far

Most people with CKD stage 3 can be looked after by their GPs but do need regular check-ups, particularly of their blood pressure

Body shape may be more important than BMI for predicting risk in CKD

New methods for predicting risk are showing promise e.g. arterial stiffness measurements

Most people with CKD consume too much salt

Reducing salt intake improves blood pressure and arterial stiffness 


So far, the feedback from the attendees has been overwhelmingly positive.   Originally, there was only going to be one event, but it proved so popular that Professor Taal hosted a second event in December for those who were unable to attend in October .  This was also well attended and the patients were very interested as they had lots of questions to ask. There was also feedback that they were very happy that the event took place.
