“…As for CFUs, it was found that the approval rate in Stage 1 was only 12.5% for the toilet flush handle surface; in Stage 3 that same surface had a 25% approval. Most bacterial populations, regardless of context (environmental, food or medical), tend to form clusters of diverse species constituting a community of microorganisms, i.e., plaques [23,24]. Thus, we cannot overlook the fact that the microbial load on surfaces can be reduced by routine cleaning of the environment, mitigating the contamination [25,26].…”

We aimed to evaluate the impact of an educational intervention on the surface cleaning and disinfection of an emergency room. This is an interventional, prospective, longitudinal, analytical and comparative study. Data collection consisted of three stages (Stage 1—baseline, Stage 2—intervention and immediate assessment, Stage 3—long term assessment). For the statistical analysis, we used a significance level of α = 0.05. The Wilcoxon and the Mann–Whitney test tests were applied. We performed 192 assessments in each stage totaling 576 evaluations. Considering the ATP method, the percentage of approval increased after the educational intervention, as the approval rate for ATP was 25% (Stage 1), immediately after the intervention it went to 100% of the approval (Stage 2), and in the long run, 75% of the areas have been fully approved. Stage 1 showed the existence of significant differences between the relative light units (RLU) scores on only two surfaces assessed: dressing cart (p = 0.021) and women’s toilet flush handle (p = 0.014); Stage 2 presented three results with significant differences for ATP: dressing cart (p = 0.014), women’s restroom door handle (p = 0.014) and women’s toilet flush handle (p = 0.014); in step III, there was no significant difference for the ATP method. Therefore, conclusively, the educational intervention had a positive result in the short term for ATP; however, the same rates are not observed with the colony-forming units (CFU), due to their high sensitivity and the visual inspection method since four surfaces had defects in their structure.

“…The use of medical devices such as urinary catheters are associated with CAUTI (Anjos et al 2020), often linked to the female gender, due to the anatomical characteristics that facilitate the ascension of microorganisms and the colonization of the vagina by members of the fecal microbiota (Conover et al 2019;Malinovski & Estorillo 2021), with the duration of catheterization being a determining risk factor for infection (Kranz et al 2020;Batista et al 2018).…”

Catheter-associated urinary tract infections continue to be of concern, given the growth of epidemiological data, costs, bacterial resistance, and complications and morbidity. Bioprospection of plants as a strategy to control pathogenic microorganisms has gained space in the literature, due to the wide diversity existing in the Brazilian flora, which allows the exploration of endophytic fungi and various compounds, to be used in planktonic cells or to inhibit the formation of biofilms. This review aims to address the formation of biofilm in bladder catheters and perspectives with endophytic fungi, secondary metabolites and bioactive compounds against pathogenic microorganisms. The present data demonstrate a favorable use of endophytic fungi in the control of gram-positive and gram-negative microorganisms. The metabolites extracted from endophytic fungi with antibacterial action can be categorized especially among the class of phenolic compounds. In addition, they can be used to control the formation of biofilms in medical devices, such as indwelling bladder catheters, which are very susceptible to microbial colonization, being responsible for severe and persistent infections.

“…The presence of biofilm in invasive devices, such as urinary catheters, is still an unmanaged threat. We highlight the importance of structural and organizational biofilm research in order to understand the most intrinsic cellular and molecular characteristics during its development (BATISTA et al, 2018;SANTOS-JUNIOR et al, 2018).…”

To map the scientific production about biofilms formation and prevention on urinary catheters. It is a bibliometric, exploratory, and descriptive research performed in Web of Science™, in three stages, and utilizing HistCite™ software. In this regard, descriptors “Biofilm*” AND “Urinary Catheter*” were utilized within the period between 1945 and 2016. A total of 329 articles about biofilm on urinary catheter were found from 1985 to 2016. These articles were written by 1,262 authors from 452 institutions located in 50 countries. The relation among the 15 selected articles, the most impacting ones, evidences the existence of experimental researches; most of them was in vitro. The control of biofilm formation on urinary catheters remains as a major challenge in the health area, because new ways are necessary to improve the prevention and minimization of this phenomenon.
