Real Clinical Practice Register of AlbUminuRia Detection in Patients With Previously undiAgnosed Chronic Kidney Disease

This register was sponsored and organized by the Association "Eurasian Association of Internal Medicine". It is a multicenter non-interventional register of real clinical practice. The database will include patients aged 40 years and older without pre-existing nephrological disease who are available for a dipstick test for albuminuria. The subjects will be identified by screening all patients who meet inclusion/exclusion criteria during routine outpatient and hospital follow-up. The register does not include follow-up (cross-sectional design). Patients eligible for the register should be enrolled and documented. The procedure for obtaining informed consent for the collection and analysis of the retrospective data must comply with the local legislation. If necessary, patients will be asked to sign an informed consent document. All study sites will use standardized electronic CRFs. The Electronic Data Capture (EDC) system should be validated in accordance with current standards and legal requirements. The investigators will log into this system using individual usernames and passwords. Data may only be entered and corrected by the investigator or other authorized study site personnel.
