Survival of patients with chronic renal failure

Abstract

Introduction:

Chronic kidney disease is among the twenty leading causes of life years potentially lost worldwide.

Objective:

To estimate global survival 5 years after the diagnosis of chronic kidney disease.

Methods:

A descriptive observational investigation of a series of case was carried out in patients diagnosed with chronic renal failure, during the five-year period
2009-2013 in two hospitals in Santiago de Cuba. The population study it was made up of the 153 patients diagnosed with the disease. The variables studied were: age, sex, clinical stage at diagnosis, renal function replacement therapy, and causes of end-stage chronic kidney disease. Absolute frequency and percentage measures and central tendency measures were used for statistical processing to estimate survival times.

Results:

The age group from 40 to 59 years predominated for 52.9%, 51% were male. The diagnosis in stage five prevailed in
70 % and 52.4% did not receive replacement treatment. The main cause of chronic renal failure was arterial hypertension in 54.3%. The median survival time was 23.5 %. Age, clinical stage at diagnosis, as well as renal function replacement therapy, had statistical significance, and intervened in the probability of survival in the predetermined time.

Conclusion:

The global survival achieved does not exceed half of the maximum time lived, in these patients it was well below the levels reached in Cuba and in the world.
