Does community-wide chronic kidney disease management improve patient outcomes?

BACKGROUND: The number of patients starting renal replacement therapy (RRT) is increasing in England, as it is worldwide. Improvements in the management of chronic kidney disease (CKD) across communities to alter this trend are a public health priority. We have prospectively studied changes in the incidence and modality of treatment for end-stage renal disease following the introduction of a CKD management programme in the West Midlands region of England. METHODS: Nephrology service to approximately 700 000 adult population of mixed ethnicity in urban and suburban areas, many with social deprivation. The programme was introduced in stages between 2003 and 2006 and comprised primary care education and financial incentives, personal clinical reports written directly to patients following every consultation, routine laboratory estimated glomerular filtration rate (eGFR) reporting, eGFR graph surveillance to identify and monitor patients at risk, multidisciplinary pre-RRT care and conservative care. Prevalent patients: 10 552 with CKD and 8509 without CKD with diabetes. OUTCOMES: access to nephrology care, trends in RRT incidence and starting modality, place of death without RRT. Incident count was adjusted for changes in the local adult population recorded in national censuses. RESULTS: Ninety-one per cent of patients aged ≥75 years with incident CKD stage 5 were known to a nephrologist. The population-adjusted incident RRT rate peaked in 2005 and then declined; the proportion starting with transplant, peritoneal dialysis or haemodialysis by arterio-venous fistula increased to 63% by 2012 (P = 0.001 versus 2005). Fifty-two per cent of patients receiving planned conservative care without dialysis died out of hospital. CONCLUSIONS: Following the introduction of a community-wide systematic CKD management programme, the population-adjusted incidence of RRT reduced, modality of initiation of RRT improved and a majority of patients receiving planned conservative care without dialysis died out of hospital.

Efficacy of the accelerated hepatitis B vaccination schedule used in haemodialysis patients post-exposure to virus: a single-centre experience.

BACKGROUND: The hepatitis B (HB) vaccination regime currently recommended for use in the UK for both preventative and post-exposure purposes is the accelerated regime, although there have been no recent reports of its efficacy. This observational study reports on the response rate achieved and longevity of protection conferred with this regime in a large number of haemodialysis patients following an episode of HB exposure. METHODS: One-hundred and five patients received primary vaccination (vaccine administered at 0, 1 and 2 months). Eighty-six completed the regime, receiving a booster dose at month 12. Measuring antibodies to HB surface antigen (anti-HBS) 6 weeks after receiving the third and fourth doses assessed patients' response. Seventy-seven patients subsequently had anti-HBs measured at month 24. RESULTS: The response rate (anti-HBS >10 mIU/ml) to primary vaccination and the complete regime was 33 and 73%, respectively. Non-European patients responded better to primary vaccination than Europeans (P=0.014). Those receiving steroids responded less well to the complete vaccination regime (P=0.007). Patient's age, sex, renal diagnosis, diabetes mellitus, time on dialysis, dialysis adequacy, erythropoietin dose, hepatitis C or body weight did not affect response rates. By month 24, 24 responders (44%) had lost seroprotection. Antibody levels achieved with vaccination by transient responders was significantly lower than persistent responders. No patients became HB surface antigen positive during the 2-year study. CONCLUSION: Reserving the accelerated vaccination to the post-exposure scenario will expose many more patients to the risk of HB cross-infection than if used prophylactically. Regular monitoring is required if seroprotection is to be maintained.
