Mortality from the Argentine Registry of Patients in Chronic Dialysis 2004-2005

Abstract

Argentina Mortality Rate in Chronic Dialysis for 2005 was 15.65 deaths per 100 patient-years at risk (p/yr), 12.72 in non-diabetic patients and 25.93 in diabetic patients (that falls to 22.03 when it is adjusted by age and sex) and SMR (standardized mortality ratio) is 1.73 in diabetic patients compared to non diabetic ones. Polycystic renal disease patients have the lowest adjusted mortality rate, followed by glomerulonephritis,
idiopathic and obstructive patients, all of them showing a meaningful lower mortality than standard.
From an indirect standardization we observe that 15 provinces (considering DC Center location) have a lower mortality rate than standard (Rate < 15.65 and SMR < 1.00); but only 3 of them are significantly lower: Río Negro, Chaco y Mendoza.
On the other hand, 9 provinces have a higher mortality than standard; but only Buenos Aires presents a significantly higher mortality (SMR 1.07, interval 1.01-1.13, Chi2=5.52).
Peritoneal dialysis, was adjusted with hemodialysis (HD) and raises its mortality from 12.99 (gross mortality) to 20.00 deaths per 100 p/yr showing 27% of higher mortality than HD (SMR 1.27), being this difference statistically significant (Chi2= 6.40).
In gross rates it is observed a higher mortality among public hospital patients, mortality for hospital patients raises up to 24.87 deaths per 100 (21.59-28.51) being SMR = 1.60 (1.39-1.83) with Chi2 = 45.5 (p<0.001).
47.6% of registered death causes are from cardiovascular origin and 24.6% from infectious origin.¨
