Caracterización bacteriana de superficies inertes en unidades móviles de atención pre hospitalaria posterior a la desinfección de la ciudad de Cuenca 2023

Abstract

Introduction: Ambulance units play a crucial role in providing prehospital care and transporting patients with serious conditions. However, they can be a source of cross-contamination, primarily bacteria, which can compromise patient health and put medical personnel at risk. This risk is further heightened if adequate disinfection protocols are not established. Objective: To characterize the bacteria present on inert surfaces after disinfection processes, in order to corroborate whether the disinfection process is adequate. Methodology: The research approach was qualitative, non-experimental, cross-sectional, analytical, and field-based. The study universe consisted of inert surfaces of the mobile pre-hospital care units. Once the suspected bacteria were analyzed, they were identified using the Vitek 2 technique, and antibiotic susceptibility tests were also performed. Results: Growth was found in 15 of the 60 sites analyzed. However, suspected bacteria were analyzed and identified: Staphylococcus hominis, Pseudomonas aeruginosa, and Bacillus spp. These strains are considered potentially pathogenic in areas of high handling. Additionally, antibiotic susceptibility tests show both sensitivity and resistance to specific antibiotics. Conclusion: It is concluded that contamination in the units is a serious issue due to its importance during transfers in critical situations. However, it can originate from various sources, putting the health of staff and patients at risk. Therefore, it is essential to maintain rigorous attention to the protocols of cleaning and optimal disinfection.
