UK Renal Registry 16th annual report: chapter 11 blood pressure profile of prevalent patients receiving renal replacement therapy in 2012: national and centre-specific analyses.

INTRODUCTION There continues to be uncertainty in the literature about which blood pressure (BP) recordings in which time period associate best with long-term patient outcomes and therefore optimal target ranges. METHODS Patients receiving renal replacement therapy (RRT) on 31st December 2012 with a BP reading in either the fourth or third quarter of 2012 were included. Summary statistics were calculated for each renal centre and country. RESULTS Data completeness for BP measurements submitted to the UK Renal Registry (UKRR) for all modalities were improved from previous years: it was better for haemodialysis (HD) patients (75% for pre-HD measurements) than for peritoneal dialysis (PD) patients (51%) or transplant recipients (41%). In 2012, the median pre- and post-HD systolic blood pressures (SBPs) were 140 mmHg and 128 mmHg respectively. The median SBP of patients on PD was 137 mmHg. Transplant recipients had a median SBP of 134 mmHg. Median diastolic blood pressures (DBPs) were 71 mmHg (pre-HD), 67 mmHg (post-HD), 78 mmHg (PD) and 79 mmHg (transplant). Only 26% of PD patients achieved the Renal Association guideline of SBP <130 mmHg and DBP <80 mmHg. Amongst transplant patients, 27% achieved the Renal Association guideline of SBP <130 mmHg and DBP <80 mmHg. CONCLUSION In 2012 there continued to be significant variation in the achievement of BP standards between UK renal centres.
