The observation period for anaemia and erythropoiesis‐stimulating agent (ESA)/iron treatment was 1 January 2015 to 31 December 2018, and for HCRU and costs was 1 April 2016 to 31 March 2018.

The prevalence of patients prescribed an antihypertensive, antidiabetic, and/or antihyperlipidaemic medication generally increased with increasing baseline CKD stage. Proportions of no treatment for anaemia decreased while ESA treatment increased with increasing CKD stage; ESA treatment increased with decreasing baseline haemoglobin levels. Patients in the ESA treatment cohort generally had more frequent events associated with HCRU and higher costs from HCRU‐associated activities (e.g., inpatient and outpatient care, pharmacy).</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>As CKD severity increased, anaemia management changed from iron use or no treatment to ESA use; however, anaemia may be undertreated across all CKD stages.
