The PRESAM Study (Predialysis Survey of Anaemia Management) is a retrospective epidemiological survey with the chief aim of evaluating the management of anaemia in patients with chronic renal insufficiency during the year preceding dialysis.

As a secondary objective, PRESAM focuses on:
- The clinical trajectory of the patient prior to the first visit to a dialysis centre
- Comorbidity profiles
- Intervening clinical events in the year preceding dialysis
- Medical treatments

Inclusion Criteria
All patients in participating dialysis centres who were started on haemodialysis or peritoneal dialysis (including those after a graft failure) between 1.9.99 and 30.11.99.

The total number of participants was 4333 patients. 74 patients from Israel participated in the survey.
