Inclusion criteria
* Patients meeting the inclusion criteria of the ND-CRIS cohort (long-term follow-up in one of the centers participating in the research, with a GFR \<60mL/min /1.73m2) * Patients included in the ND-CRIS cohort on the date when the estimate of their GFR is strictly less than 30mL/min/1.73m2 and greater than or equal to 15mL/min/1.73m2 (MDRD equation). Patients should have at least two measurements of GFR \<30mL/min/1.73m2 to be included, at least one of them greater than or equal to 15mL/min/1.73m2. The date of the first GFR \<30mL/min/ 1.73m2 will be considered as the date of origin.
Exclusion criteria
* Patients with GFR ≥30mL / min / 1.73m2 or \<15mL / min / 1.73m2 * Patients who do not meet the inclusion criteria of ND-CRIS cohort (dialysis patients, transplant patients, unfollowed patients)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evolution of estimated Glomerular Filtration Rate (GFR) according to MDRD equation (modification of diet in renal disease) at each visit | up to 3 years | — |
| Time between inclusion and occurrence of the progression event | up to 3 years | progression: initiation of an extra-renal purification technique or reduction of GFR of at least 5 mL / min / 1.73m2 compared to inclusion in FAIR-PROGRESS |
