Objective: To determine the fraction of patients with end-stage renal disease (ESRD) who received dialysis treatment in the city of São Paulo in 1991 and to investigate the influence of age in the access to dialysis.
Material and methods: All patients who received dialysis for ESRD in the city of São Paulo during 1991, and were registered in the Secretary of Health of São Paulo files were included in the study. In the same year, information was also collected on individuals who died having as basic cause of death a disease related to chronic renal failure. These data were obtained from death certificates files. Using simultaneously information from both data bases it was possible to ascertain the patients who died without receiving dialysis and to calculate the treated fraction in several age groups.
Results: Overall 25.6% of ESRD patients did not receive treatment. There was a progressive reduction in the fraction of patients treated for those older than 40 years. In children less or equal to 9 years of age the percentage of treatment was also reduced (29%). Individuals in the age groups 60-69 and 70-79 years had a chance about 5 and 11 times greater, respectively, of dying without receiving dialysis than those in the 20-29 years group.
Conclusions: We estimate that at least one fourth of the ESRD patients died in São Paulo in 1991 without receiving dialysis treatment. Age is a major factor of discrimination for acceptance in chronic dialysis programs.
