Title of studentship

Changes in the prevalence and referral characteristics of advanced chronic kidney disease (CKD) in Northern Ireland from 2001-2007. Have CKD guidelines improved health?


Project outline

Chronic Kidney Disease (CKD) affects 5-8% of the UK population and is the pathway through which the vast majority of end-stage renal failure patients pass before needing dialysis. The majority of patients are identifiable many years beforehand. This proposed research aims to assess the characteristics of patients and practices with respect to late referral to renal services. What is novel in this study compared to our previous work is the linkage to the Northern Ireland Longitudinal Study, the use of eGFR classification for CKD and the detailed information now freely available on general practices from QoF performance. Specific aims are therefore to ascertain:

1) The proportion of patients with documented laboratory stage 4 or 5 CKD referred to renal units/nephrologists over time from 2001 through to 2007.

2) Characteristics of late referred patients (in 3 categories: >12 months, 3-12 months and <3 months) with respect to age, associated diabetes, anaemia, test source (specialty).

3) Characteristics of general practices that refer patients with respect to practice size, rurality, deprivation and practice performance in the 2004-2008 QoF indicators. Temporal changes in these features across the 2004-2008 timeframe will also be assessed.

4) Finally for the subset of patients with potential linkage to the Northern Ireland Longitudinal Study we would like to assess the role of cultural, demographic, economic, health, housing and social issues that may influence referral of chronic kidney disease to secondary care services.


This project will merge existing data in the Centre for Public Health using the recently expanded 6 years of laboratory data covering Northern Ireland in 2001-2007. Additional laboratory tests such as haemoglobin, lipids, CRP and bone parameters have been downloaded after the appropriate ethical and data protection steps. These patient level covariates will be used in conjunction with our detailed profile of all 360 general practices using the publicly available Quality and Outcomes Framework performance.
