Flozination: a rolling quality improvement programme

Abstract Background and Aims Sodium glucose linked transporter-2 inhibitors (SGLT2i) reduce renal and cardiovascular end points in people with chronic kidney disease (CKD), both with and without diabetes. Despite exciting data from the CREDENCE and DAPA-CKD trials, implementation of new evidence to every day clinical practice can be challenging. We present the results of a rolling quality improvement project regarding SGLT2i prescription. The aim of the project was to support clinicians in the evidence based prescribing of SGLT2i for CKD. Method Three renal units who share a single electronic clinical database agreed a joint protocol and staged implementation programme. These tertiary referral renal units cover a population of around 2.3 million people. The important timeline regarding SGLT2i licensing and interventions is shown in Figure 1. Interventions were as follows: 1. Identification of patients meeting the licensing criteria for prescription of canagliflozin for CKD with diabetes. 2. Addition of an alert to the electronic patient record. 3. SGLT2i protocol developed and advertised via poster in outpatient clinic sites. 4. Evaluation of clinician attitude to prescribing. 5. Measurement of number of patients meeting the licensing criteria for prescription of dapagliflozin for CKD with and without diabetes. Measurement of SGLT2i prescription was audited from the electronic record. Results In the first wave of the programme, 326 patients were identified as suitable under the initial licensing criteria for canagliflozin, and electronic alerts were added to the records of these patients. When measuring number of patients who may be suitable under the dapagliflozin licensing, there were 562 patients with diabetes and 5262 without diabetes. In a survey of clinician attitudes, 94% suggested they felt well equipped to prescribe SGLT2i. Prescribing of SGLT2i across time is shown in Figure 2. 1146 patients have been prescribed SGLT2i. Age was 64±13 years, and the majority were male (68%) with type 2 diabetes mellitus (61%). Most (73.6%) were treated with angiotensin converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB). More than half (54%) of patients live in areas with high levels of socio-economic deprivation (Scottish Index of Multiple Deprivation quintiles 1 or 2). Estimated glomerular filtration rate was 40.9±23.5ml/min/1.73 m2 and Kidney Failure Risk Equation (KFRE) 5 year risk of end stage kidney disease (ESKD) was 23.2±28.2%. In comparison with the general outpatient clinic population, the distribution of socioeconomic deprivation was similar, but a higher proportion were female (46%). Conclusion An iterative quality improvement project was designed around the evolving drug licensing of SGLT2i and capitalised on local strengths, including an effective and well used clinical electronic database shared across renal units. Clinicians have been supported in SGLT2i prescribing with highly visible clinical protocols, and electronic alerts to highlight candidate patients. A high level of SGLT2i prescribing has been achieved in a population at high risk of ESKD. Further interventions should focus on prescribing in groups where gaps have been identified – such as women and those without diabetes. Other units would be recommended to capitalise on existing strengths, exploit the use of clinical databases, and ensure protocols are inclusive and well-advertised in order to optimise evidence based treatment of CKD.
