Plain English Summary
Background and study aims
Anaemia is a condition where a lack of iron in the body results in a lower than usual number of red blood cells. This means that there isn't as much oxygen being delivered to the organs and tissues. This can cause a number of problems, including tiredness, breathlessness, heart palpitations and even heart failure. Anaemia is common in people with chronic kidney disease (CKD) and is associated with poor health outcomes. This study aims to develop and test a step-wise model of intervention for treating anaemia in people with CKD in primary care. It is hoped that this treatment model will improve the health of people with CKD and anaemia.
Who can participate?
General practitioners (GP) and also adult CKD patients with anaemia.
What does the study involve?
The study has two phases.
In phase 1, GPs and patients are invited to take part in group discussions in order to explore what difficulties there are in managing anaemia in CKD patients and how best to run phase 2.
In phase 2, GP practices are randomly allocated into one of two groups. Those in group 1 (usual practice), treat their patients as usual. Those in group 2 (intervention) treat their patients according to the step-wise model of intervention. This includes confirming diagnosis, taking simple steps to improve the patients’ condition (such as stopping medications that may cause bleeding), giving patients iron tablets and, if their condition warrants it, intravenous iron or erythropoiesis-stimulating agents (medication that stimulates the production of red blood cells). Health outcomes for all participants are measured at the start of the study, 6 months later and then after a year.

Participant inclusion criteria
Phase 1: In-depth discussion
Practitioners and patients from four GP practices will be invited to take part in the in-depth discussions. These four GP practices will be purposefully selected on the following criteria:
1. Achievement of Quality Outcome Framework (QOF) points for CKD
2. At least the national average of people aged over 65 years (as CKD particularly affects older people)
Phase 2: Clustered Randomised Trial
Practice level:
1. GP Practices should be computerised and have had the same computer system for at least 3 years; they should have had laboratory-links (ensuring completeness of pathology results) for this period; and a practice computer system using 5-byte Read codes (commonest used in UK), or Clinical Terms Version 3 (CTv3).
2. Practices have space for the review clinic and consent to participate.
Patient level:
1. Adult patients registered with participating practices with CKD (stage 3 and 4) and anaemia (Hb=11g/dl), who are not under the care of a renal physician, and without an obvious other cause for their anaemia (i.e. overt cause of blood loss)

Target number of participants
Planned Sample Size: 24; UK Sample Size: 24; Description: The study will recruit 4 GP practices for diagnostic analysis in Phase 1 and 20 GP practices the cluster randomised trial in Phase 2 (a total of 24 GP practices).
Participant exclusion criteria
Practice level:
1. Practices with plans to change computer systems during the proposed 3-year study
2. Practices involved in the in-depth group discussions at Phase 1 will be excluded from taking part in Phase 2.
Patient level:
1. Patient under 18 years of age
2. Those unable to consent
3. Those receiving dialysis or who have had a renal transplant
4. Those with previous adverse reaction to iron
5. Those currently or previously treated with erythropoietin
6. Those who have expressed a wish to opt out of sharing electronic records to their GP (identifiable by the present of an 'Optout Read codes’: 93C1, or 'Refused consent for upload to local shared electronic record': 9Nd1 in the GP information systems).
