The future of haemodialysis in the UK RCP advanced medicine 2013 Cormac Breen Consultant Nephrologist Guy's and St Thomas' Hospitals London
Plan • Overview and demographics of haemodialysis • Description of technical challenges and opportunities of thrice weekly unit dialysis • Vascular access • Self-care • Haemodialysis at home. • Extended hours high-frequency for improving clinical outcomes and quality of life • Viewing dialysis in terms of cost and quality in relation to NHS funding

Demographics of RRT • Prevalence rate RRT All UK centres 51,835 • (Total UK population 62.3 million) • Prevalence rate All RRT (pmp) 832 (428-1408) • Prevalence rate HD 360 • Prevalence rate PD 64 • Prevalence rate dialysis 424 • Prevalence rate transplant 408

Centre-based haemodialysis • The vast majority of Haemodialysis delivered in dialysis centres (hospital and satellite) • Most have standard Haemodialysis (diffusive) • Smaller proportion have Haemodiafiltration (convective with infusion) • All new dialysis centres generate ultrapure water, much lower rates of contamination • Standardised treatment with improving outcomes

The quality challenges of Centre-based HD • Travel times and Scheduling • Treatment times • The 3 day gap • Inflexible approach to the therapy • Cost

Cost of Centre-based HD • Satellite unit Kent 80 patients (2011) • Total annual income £1,738,464 • Variable costs non-pay £591,840 (transport 20%) • Fixed costs non-pay £222,005 • Fixed costs pay £681,082 (91% nursing) • Opportunity to reduce costs mostly from reducing requirement on nursing staff and on transport
Provision of Haemodialysis facilities in flat cash NHS • Originally all dialysis units in main hospital centres • Growth of satellite Haemodialysis a mix of units built from NHS capital and units run by private providers with patient cohorts contracted • Wide variation in costs, per sqm, per dialysis chair • Little if any opportunity for NHS capital investment from now on • 2 options: contract capacity from private provider; make more use of home dialysis

Vascular access • All patients on haemodialysis dependent on stable circulatory access for good treatment • Options are for native arteriovenous fistula, PTFE graft, or percutaneous venous catheter • “Quality measure” AVF = AVG > catheter • Best practice tariff £159 > £128

Improved ‘modern’ approach to home HD • Address the quality gap • Improve cost efficiency • Reduce the dependence of dialysis facilities • Reduce the dependence on nurses • Move care out into the community • Improve clinical outcomes, quality of life

Getting the dialysis schedule right When we talk about survival with patients we need to be making meaningful comparisons

More dialysis vs more restrictions • Shorter gaps vs fluid gain & BP • Higher HD dose vs more pills • Recovery time quicker (min vs hrs) • More free time vs better free time Getting the dialysis schedule right 44
Getting the dialysis schedule right • Which clinical parameters matter most to patients? • Do our usual markers help us? • Should other blood values indicate more factors to the patient? • Keeping the patient well and free of complications matters most 45
More dialysis vs more restrictions • Shorter gaps vs fluid gain & BP • Higher HD dose vs more pills • Recovery time quicker (min vs hrs) • More free time vs better free time Getting the dialysis schedule right 46
Daily nocturnal HD compares favourably to first deceased donor Tx • No data for older, comorbid pts • No data for higher immunological risk pts • Should this be part of discussion of RRT choices? Transplantation or not Pauly et al 47
