Abstract

in English, Spanish

Background:

Infections associated with health care, previously known as nosocomial infections, constitute one of the main causes of morbidity and mortality in hospital. The aim of this study is to estimate the lethality of HAI, as well as the risk of dying from HAI versus mortality by other causes.

Methods:

We analyzed the historical cohort of IAAS of the Epidemiology service of a tertiary-level hospital, from 2012 to 2017. The incidence analysis and the probability of death of IAAS were made against other causes, as well as the analysis of age, period-cohort of lethality of IAAS.

Results:

The incidence of IAAS ranged from 27.9 to 31.5 IAAS/1000 person-days between 2012 and 2017, the probability of having an IAAS in ICU is 3.51 (CI95%: 2.93-4.20), p < 0.01, NAVM lethality against any other causes of death had a relative risk (RR) of 6.06 (CI95%: 2.91-12.6) in 2016, RR was 4.01 (CI95%: 1.59-10.09) in ITUAC in 2015, no effect of age, cohort or period in the case of IAAS was identified.

Conclusions:

IAAS remain to be an important public health problem in our country, without excluding our medical unit, it is important to redirect efforts to reduce them in the medium term.
