Variation between centres in access to renal transplantation in UK: longitudinal cohort study

To assess whether equity exists in access to renal transplantation in the UK after adjustment for case mix in incident patients with end stage renal disease.

Longitudinal cohort study.

UK Renal Registry and UK Transplant Registry.

All incident renal replacement treatment patients (n=16 202) from 65 renal centres submitting data to the UK Renal Registry between 1 January 2003 and 31 December 2005, followed until 31 December 2008 (or until transplantation or death, whichever was earliest).

Proportion of incident dialysis patients at each renal centre who were registered on the national transplant list; time taken to achieve registration; and proportion of patients subsequently transplanted.

We found that recipients' age, ethnicity, and primary renal diagnosis were associated with the likelihood of accessing the waiting list or receiving a transplant. After adjustment for case mix, significant inter-centre variability existed in access to the transplant list (change in -2LogL=89.9, df=1, P<0.001), in the time taken to register patients on the waiting list (change in -2LogL=247.4, df=64, P<0.001), in receipt of a renal transplant from a donor after brain stem death (change in -2LogL=15.1, df=1, P=0.001), and in receipt of a renal transplant from a living donor or a donor after cardiac death (change in -2LogL=46.1, df=1, P<0.001).

Significant variation in access to renal transplantation exists between centres within the UK that cannot be explained by differences in case mix.
