A Quality Improvement Process to Increase and Sustain a Peritoneal Dialysis Programme in the United Kingdom

Peritoneal dialysis (PD) remains underutilised in the West. The proportion of patients in the UK starting renal replacement therapy (RRT) with PD fell from 7.2% in 2011 to 6.0% in 2016. At our centre, 8.4% of dialysis patients received PD in April 2014. Evidence suggests that home dialysis improves patient clinical outcomes; therefore, a target was agreed to achieve 25% of dialysis patients receiving PD by 2018.

A rapid improvement process was introduced, as a quality improvement tool, to increase and sustain the PD programme. With multidisciplinary team support for PD growth, a nephrologist was trained to insert PD catheters. Nurses were trained to provide patients with balanced pre-dialysis information and discuss alternative dialysis modalities with haemodialysis (HD) patients. The "Acceptance, Choice and Empowerment" project raised awareness of home therapy choices, using a peer educator model specifically for ethnic minority patients. Lean methodologies were used to ensure continuous quality improvement.

PD uptake increased from 37 to 84 patients, giving a PD penetration increase from 8.4% to 19.1% between April 2014 and March 2018. Catheter insertions increased from 94 at the end of QI Period 1 to 185 at the end of QI Period 2, representing a 97% increase, with the medical/surgical split remaining stable. Peritonitis rates remained stable, and PD drop off to HD reduced from 52% to 41% during the same period.

By implementing a rapid improvement process and embedding a quality improvement programme, the number of incidents and prevalent PD patients increased and was sustained.
