Chapter 1: UK RRT Incidence in 2009: National and Centre-Specific Analyses

Abstract

This chapter describes the characteristics of adult patients starting renal replacement therapy (RRT) in the UK in 2009 and the acceptance rates for RRT in Primary Care Trusts and Health Boards (PCT/HBs) in the UK. The basic demographics and clinical characteristics are reported on patients starting RRT from all UK renal centres. Late presentation, defined as time between first being seen by a nephrologist and start of RRT being <90 days was also studied. Age and gender standardised ratios for acceptance rates in PCT/HBs were calculated. In 2009, the incidence rate in the UK and England was 109 per million population (pmp). Acceptance rates in Scotland (104 pmp), Northern Ireland (88 pmp) and Wales (120 pmp) had all fallen although Wales still remained the country with the highest acceptance rate. There were wide variations between PCT/HBs with respect to the standardised ratios. The median age of all incident patients was 64.8 years (IQR 50.8, 75.1). For transplant centres this was 63.0 years (IQR 49.0, 74.2) and for non-transplanting centres 66.3 years (IQR 52.6, 75.9). The median age for non-Whites was 57.1 years. Diabetic renal disease remained the single most common cause of renal failure (25%). By 90 days, 69.1% of patients were on haemodialysis, 17.7% on peritoneal dialysis, 6.7% had had a transplant and 6.5% had died or stopped treatment. The mean eGFR at the start of RRT was 8.6 ml/min/1.73 m2 which was similar to the previous two years. Late presentation (<90 days) has fallen from 27% in 2004 to 19% in 2009. There was no relationship between social deprivation and presentation pattern. Acceptance rates have fallen in Northern Ireland, Scotland and Wales whilst they have plateaued in England over the last four years. Wales continued to have the highest acceptance rate of the countries making up the UK.
