Background: During 1980-1990, different programs were created in Chile in order to reduce chronic renal failure (CRF) morbimortality in children and adolescents. Objective: To describe CRF mortality and proportion of deaths in a period of 20 years. Method: CRF mortality rate and death proportion per year were calculated 1984-2003 in patients younger than 19 years-old. Temporal trends were analized comparing CRF risk of dying in the extreme trienniums (1984-1986 and 2001-2003); the same methodology was used to characterize CRF death temporal trend. Results: CRF risk of dying in the triennium 1984-1986 was 3.7 times greater than the triennium 2001-2003 (p = 0.01). The comparison of CRF death proportion did not differ among extreme trienniums (p = 0.68). Conclusion: CRF mortality rate decreased between 1984-2003, meanwhile CRF proportion of deaths remained stable. This behavior is explained by a proportional decrease of CRF mortality rate in relation to other causes of greater incidence (e.g. infectious diseases), as well as displacement of occurrence to older ages
