Mortality of people with chronic renal failure, at the Instituto Salvadoreño del Seguro Social 2000-2016

Abstract

Objective. Define chronic renal failure (CRF) patients clinical evolution in the Salvadoran Social Security Institute (ISSS) hospitals.
Methodology. Multivariate cross section secondary sources analysis, estimated sample for finite populations: 375 cases (Conf.95, alpha 5%), Collection and processing: EXCEL and STATA 14.0.
Results. 65.3% was men, average age: 57 +/- 17, 68.5% was 50 years or older, 23.7% has high blood pressure (HBP) 16% diabetes mellitus (DM) and 8.8% chronic heart disease, death rate was 21.8%, Direct causes of death: Chronic Renal Failure (CRF): 63.6%, infections: 14%, cardiovascular events: 10.9%, estimated years of potential life lost (YLL): 877 (60.5% in men). The 50.1% of the patients had CRF since the first hospital discharge, one-year survival: 93% and 71% at 10 years, co morbid (Log Rank / p)HBP 12.3 / 0.0005, diabetes: 4.9 / 0.027 (together: 16.6 / 0.0008), Chronic obstructive pulmonary disease (COPD): 6.45 / 0.011, age over 50: 5.45 / 0.019, more than 2 co morbidities: 14.26 / 0.0065. The death risk was increased by COPD (HR / 95% CI / p): 3.92 / 1.23-12.6 / 0.055, HBP: 2.16 / 1.38-3.38 / 0.0012, diabetes: 1.79 / 1.05-3.07 / 0.0043 and age over 50: 1.83 /1.1-3.09/0.016.
Conclusions. CRF affected men older than 50 years, they generated most years of potential life lost, major etiologies: high blood pressure, DM and chronic heart disease, was the main direct cause of death, half of people already had CRF since their first hospital discharge, 10-year survival was 70%, mortality due CRF with HBP, DM, COPD and age> 50 years old is greater than when they do not present them and increase the risk of dying.
