Epidemiology, clinical profile, management, and two-year risk complications among patients with chronic kidney disease in Spain

Abstract

Objectives: To describe the epidemiology, clinical profile, treatments, and to determine cardiovascular and renal outcomes after two years of follow-up in a contemporary chronic kidneay disease (CKD) population in Spain. This was also analyzed among the DAPA-CKD-like population (patients who met most inclusion criteria of DAPA-CKD trial). Methods: Observational, retrospective, population-based study using BIG-PAC database. The CKD population was defined as patients >= 18 years, with at least one diagnostic code of CKD prior to the index date (January 1st, 2018). CKD was defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2(CKD-EPI), or albuminuria >30 mg/g. Results: We identified 56,435 CKD patients after exclusions (76.4 years, 52.2% men, urine-album into-creatinine ratio 390.8 mg/g, eGFR 49.7 mL/min/1.73 m(2)). CKD prevalence was4.91% and incidence 2.10 per 1000 patient-years. Regarding treatments, 69.2% were taking renin-angiotensin system inhibitors (only 4.2% at maximal doses) and 3.5% of diabeticpatients SGLT-2 inhibitors. During the two years of follow-up, rates of heart failure, all-cause death, myocardial infarction, stroke, and CKD were 17.9, 12.1, 7.2, 6.3, and 5.9 events per 100 patient-years, respectively. During this period, 44% of patients were hospitalized, and 6.8% died during hospitalization. Cardiovascular outcomes were more common in the DAPACKD-like population. Conclusions: In Spain, CKD population is older and comorbidities, including diabetes and heart failure, are common. Cardiovascular and renal outcomes are frequent. There is room for improvement in CKD management, particularly through the use of drugs with proven cardiovascular and renal benefit. (C) 2021 Sociedad Espanola de Nefrolog ' ia.
