Introduction:

infections associated with health care (IACS) have a strong social and economic impact; likewise, they constitute an indicator of the quality of care in hospitals. Objective: to identify the risk factors that influence independently to acquire bacteremia associated with health care.

Methods:

an observational, analytical study of cases and controls was carried out, 48 cases and 144 controls were selected. With a ratio of 1:3. Univariate and multivariate statistical analysis was performed.

Results:

in the univariate analysis, comorbidity, the use of a nasogastric tube and a bladder catheter did not show a statistically significant influence, while the multivariate analysis showed that the most important independent factor was the use of a central venous catheter (OR 11,837 adjusted CI 95% 4,493-31,180), followed by the presence of septic shock on admission to the PICU (OR 4,908 adjusted 95% CI 1,152-20,907) and the presence of ostomies (adjusted OR 10.44 95% CI 2,806−17,836) in a similar way.

Conclusions:

comorbidity, the use of a nasogastric tube and the use of a bladder catheter did not contribute to the risk of acquiring healthcare-associated bacteremia. The presence of a central venous catheter, the presence of septic shock on admission to the PICU, and the presence of ostomies were the highest risk factors.
