OBJECTIVE
Epidemiological data about the treatment of patients with end-stage renal disease in the Great Sao Paulo, Brazil, are presented.


METHODS
Patients on dialysis in the city of Sao Paulo and surroundings, distributed in 15 Regional Offices of Health (ERSAs), during 1991, were studied. Data were collected by the Secretary of Health of the State of Sao Paulo.


RESULTS
There was an increase of 18.6% in the number of alive patients on dialysis from January 1 to December 31 (n = 2,425 to 2,875). Patients were treated in 40 dialysis centers, of which 24 were located in the ERSAs 1, 2 and 3. Depending on the ERSA, a percentage of patients varying from 37% to 88% did not live in the same region where they received treatment. At the end of the year, 79% of the patients were on hemodialysis, 15% on continuous ambulatory peritoneal dialysis and 6% on intermittent peritoneal dialysis. The diagnoses more frequently reported of primary disease were non-determined, glomerulonephritis, hypertension and diabetes (36%, 27%, 17% and 8%, respectively). New cases (1,483) initiated dialysis during the year, corresponding to an incidence rate of 83 patients per million population (pmp). The prevalence of patients on dialysis was 148 pmp. The annual fatality rate was 17.2% (range in the ERSAs: 12.0-3.5). The actuarial one year survival for the patients who started treatment in 1991 was 80.2%. 246 patients received transplantation, corresponding to 14 patients pmp.


CONCLUSIONS
Dialysis treatment provided in the Great Sao Paulo is satisfactory.(ABSTRACT TRUNCATED AT 250 WORDS)
