P0799EPIDEMIOLOGY AND TREATMENT PATTERN OF HYPERKALAEMIA AMONG OUTPATIENTS IN CHINA: A DESCRIPTIVE STUDY USING AN ADMINISTRATIVE DATABASE IN CHINA

Abstract Background and Aims At present, the clinical burden and treatment pattern of hyperkalaemia among outpatients in China is not well characterized. The aim of this study was to evaluate the disease distribution and treatment pattern of hyperkalaemia among outpatients in China. Method Data were derived from Beijing Data Center for Rational Use of Drugs, which contains primary records of 157 hospitals, covering 30 provinces in China. Patients who accessed outpatients (aged >=≥18 years old) with record(s) of serum potassium (S-K) between 2015.1.1- 2017.12.31 were included. The laboratory test, diagnoses, and treatments were analyzed. Hyperkalaemia defined as S-K > 5.0 mmol/L. A hyperkalaemia episode was defined as one or more consecutive S-K > 5.0mmol/L measurement(s) within 7 days. If there was a return to S-K 5.0mmol/L), in which 28,254 patients (0.94%), experienced S-K ≥5.5mmol/L. In patients with chronic kidney disease, heart failure, hypertension, and diabetes mellitus, the proportions of patients who experienced hyperkalaemia were 22.89%, 12.54%, 7.11% and 6.51%, respectively. Composition proportion of who experienced S-K ≥ 5.5mmol/L, in the patients with CKD and HF, defined as the proportion of patients experienced S-K≥ 5.5mmol/L in all hyperkalaemia patients, were 39.27% and 32.16% respectively, higher than the g
