This is epidemiological (observational) cross-sectional survey. Data for the research will be obtained from clinical records and patient´s questionnaires and transcribed into electronic case report forms (eCRF) by physician anonymized using subject ID.~This observational research will not impose any additional procedures, assessments, or changes in addition to the routine management of subjects.~The research does not aim to follow treatment with a single medicinal product. The management of patients will be described in general terms. Names of active substances will be collected rather than the names of individual products.
The decision making in the Czech nephrology offices depends on the local common practice which is likely to be heterogenous. In other words, the same patient would be indicated to different therapy and regimen at different sites. To date, the practices and treatment paths have not been described. The aim of the present epidemiological research is to characterize the population of CKD patients at the point of treatment choice and to outline the motivation of nephrologist to initiate particular therapy.
