- Abstract
Health Care-Related Infections (HAI) occur more frequently in the Intensive Care Unit (ICU) due to the greater exposure of patients to invasive procedures and devices, weakened clinical status and their handling by the care team, requiring high use of antimicrobials, which can promote a risk of developing bacterial resistance to these, whose consequences may be difficult treatment, prolonged hospitalization, risk of death and higher associated costs. It aims to describe the IRAS relating the etiological agents and antimicrobial treatment in an ICU of a reference hospital in the mesoregion of Rio Grande do Norte. This is a descriptive, retrospective and cross-sectional study with a quantitative approach. A total of 1,682 patients admitted to the general ICU of the hospital studied between 2017-2020 were included. Data were collected from registration forms that were tabulated and analyzed in Microsoft Office Excel® and Statistical Package for the Social Sciences software using simple descriptive statistics with presentation of frequencies, trends and dispersion. The analysis of the results revealed a median age of 57 years, prevalence of males and the existence of comorbidities in 57.9% of cases, especially infection prior to admission to the ICU. The average length of stay in the ICU was 11.4 days and the mortality rate was 52%. As for invasive devices, the use of an indwelling urinary catheter (96.8%), mechanical ventilation (79.4%) and central venous catheter (83.7%) was observed. There were 790 IRAS in the ICU with bacterial growth in 21.67%. The main HAI incidence densities (DI)/1,000 patient-days were: IPCSL-CVC 1.8; PAV 27 and UTI-AC 22.3. As for antibiotics, a Length of therapy of 872.5/1,000 patient-days was observed, with the most prescribed being: vancomycin (N=633), meropenem (N=625), ceftriaxone (N=479), amikacin (N= 463) and polymyxin B (N=448). The highlighted values of Days of therapy/1000 patient-days: meropenem (N=305.7), amikacin (N=260.4), polymyxin B (N=256.4), vancomycin (N=229.3) and imipenem (N=165.3). The most isolated bacteria in cultures were: Acinetobacter spp., Pseudomonas spp. and Klebsiella spp., which showed resistance mainly to: Ceftazidime (51.5% - 87.3%); cefepime (61.6% - 85.3%); ciprofloxacin (56% - 84.6%) and meropenem (31.7% - 80.3%). Non-compliance was identified in the treatment with antibiotics in 455 patients, which mainly involve polymyxin B, vancomycin, meropenem and ceftriaxone. It is concluded that there are high levels of ICU length of stay and use of invasive devices, as well as high IRAS ID with microbiological identification of important bacteria, especially due to their accentuated resistance profile, with emphasis on antibiotics from the carbapenem class and cephalosporins from 3rd and 4th generation. Also noteworthy is the presence of non-compliance in the administration of antibiotics that may contribute to the selection of multidrug-resistant bacteria.
