Introduction:

Infections related to critical care settings are associated to high death risk and significant costs.

Objective:

Identify the germs most commonly found in cultures and their resistance to antimicrobials in the intensive care service of “Dr. Joaquín Albarrán” Provincial Clinical Surgical Hospital.

Methods:

A retrospective descriptive study was conducted at the intensive care service of Dr. Joaquín Albarrán Provincial Clinical Surgical Hospital from January 2015 to December 2018. The study universe was 1 847 cultures, from which 654 were selected in which growth was obtained. Data were processed with the statistical software SPPS 22.0.

Results:

Of the germs isolated, Klebsiella spp. were the most common (31%), followed by Staphylococcus spp. (24.5%) and E. coli (9.8%). Klebsiella spp. were frequent in sputum cultures (45.1%), Staphylococcus spp. in blood cultures (53.6%) and Candida in urine cultures (41.1%), followed by E. coli (27%). Among the antimicrobials used to treat Klebsiella spp., E. coli, Acinetobacter and Pseudomonas spp., the most recommended is colistin (0-25% resistance) and vancomycin for Staphylococcus spp. (1.8%).

Conclusions:

Gram-negative germs continue to be the most commonly isolated in cultures from intensive care patients, with a high level of resistance to most antibiotics.
