KEYWORDS 2 chronic kidney disease, drug therapy, quality indicators, inappropriate prescribing, general practice, quality use of medicine, primary care 3 Abstract Background: Drugs are commonly used in patients with chronic kidney disease (CKD) to treat an underlying cause, or its numerous complications and comorbidities. The objective of this study was to examine the quality of prescribing in patients with CKD in Australian general practice from February 01, 2016 and June 01, 2016, using

We used 16 internationally validated prescribing quality indicators focused on medication need, choice and safety in patients with CKD, and we compared results for patients using clinical and sociodemographic factors. Results: Among 44,259 patients with evidence of CKD stages 3-5, 13,263 (30%) had documentation of a diagnosis of diabetes. Less than half of all patients (40.8%) with CKD stages 3-5 and aged 50 to 65 years were prescribed a statin. The use of an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) was higher in patients with concomitant diabetes (64.1%) compared with those without diabetes (51.5%; P<0.001), yet only 69.9% of the patients with diabetes and microalbuminuria were receiving an ACEI or ARB. There were 7,426 patients (16.8%) with CKD stages 3-5 potentially receiving non-steroidal anti-inflammatory drugs (NSAIDs), including 14.3% of those patients with an estimated glomerular filtration rate (eGFR) below 30 mL/min/1.73 m2. Potentially inappropriate medication use was more common in CKD patients living in relatively disadvantaged socioeconomic areas, as well as in regional and remote areas. Conclusions: We identified areas for possible improvement in the prescribing of preventive medications, as well as deprescribing of potentially nephrotoxic medication, in patients with CKD stages 3-5. Australian programs working to improve quality use of medication need to focus on improving the appropriate prescribing of recommended preventive medications in patients with CKD, such as an ACEI/ARB and statin, and deprescribing of NSAIDs in patients with concurrent ACEI/ARB therapy.
