Supplementary Material for: Effect of a Quality Improvement Program to Improve Guideline Adherence and Attainment of Clinical Standards in Dialysis Care: Report of Outcomes in Year 1

<p><b><i>Background:</i></b> Best practice in dialysis is synthesised in clear international guidelines. However, a large gap remains between the international guidelines and the actual delivery of care. In this paper, we report outcomes for the first year of a multifaceted dialysis improvement programme in our network. <b><i>Methods:</i></b> One year collaborative involving 3 haemodialysis units and a peritoneal dialysis (PD) programme involving 299 dialysis patients. Each unit addressed a different indicator (unit A - catheter-related bloodstream infection [CRBSI], unit B - pre-dialysis blood pressure [BP], unit C - dialysis dose, unit D - anaemia) with a shared aim to match the top 10% in the UK. Tailored multifaceted approaches include a modified collaborative methodology with an aim, framework, driver diagram, learning sessions, facilitated meetings, plan-do-study-act cycles and continuous measurement. Analysis of outcomes, costings, erythropoietin stimulating agent and iron use, and safety culture attributes. <b><i>Results:</i></b> Unit A reduced CRBSI from 2.65 to 0.5 per 1,000 catheter days (<i>p</i> = 0.02). Unit B improved attainment of target BP from 37.5 to 67.2% (<i>p</i> = 0.003). Unit C improved attainment of target urea reduction ratio from 75.8 to 91.4% (<i>p</i> = 0.04). PD unit D improved attainment of target haemoglobin from 45.5 to 62.7% (<i>p</i> = 0.01), with no significant change in the indicators in a non-intervention unit. Safety culture attributes improved. Costs associated with admission for fluid overload and infection, erythropoietin, iron and thrombokinase use decreased 36% (£415,620-£264,143). <b><i>Conclusions:</i></b> Units that took part in this collaborative improved guideline adherence compared both to their own pre-intervention performance and a non-intervention unit. Such multifaceted interventions are a useful methodology to improve dialysis care.</p>
