OBJECTIVES:

To determine the frequency of nosocomial infections due to Acinetobacter baumannii and to identify the characteristics influencing the probability of these infections.

MATERIAL AND METHOD:

An analytical cross-sectional design was carried out, including all patients with a positive culture report for Acinetobacter in the General Hospital of Ticoman, Mexico City, from January 2016 to December 2017. SPSS and Graphpad Prism 0.7 software were used for statistical analysis with x 2 homogeneity, survival analysis with Kaplan-Meier estimate, OR and Mann Whitney U test.

RESULTS:

An analysis of 80 patients was performed, 2 groups were formed: dead (n = 40) and alive (n = 40) with Acinetobacter infection. Mean age was 52 ± 16 years, 61.3% were male; mean hospital stay was of 28 ± 19 days, the most frequent infectious focus was pulmonary (72%); 76% required mechanical ventilatory support, a cut-off was performed based on ventilation days < 7 days and > 7 days, obtaining p value = 0.0013. The survival analysis with Kaplan-Meier concluded that the stay in Internal Medicine increased mortality (p = 0.012).

CONCLUSION:

Survival decreases in patients with ventilatory support for > 7 days and pulmonary infectious focus.
