Urinary tract infections caused by indwelling urinary catheters are one of the most common healthcare-associated infections. The catheterization procedure is considered a minor surgical intervention, and therefore the catheterization itself must be performed in aseptic conditions. With the introduction of a catheter, the risk of bacteriuria increases with the time since the catheter is present, with an average daily risk of up to about 10%. It is necessary to assess the patient's needs for urinary catheterization every day, and the catheter should be removed as soon as possible. The research part of the work was conducted on 160 nurses and technicians, of which 17 were men and 143 were women with different levels of professional education and different years of service. The formed survey questionnaire examined the knowledge of nurses and technicians through 13 questions, and in the second part of the survey, participants expressed their views through 6 stated statements. They expressed their views through five degrees of agreement or disagreement with the stated statement (1. complete disagreement, 2. disagreement, 3. neutrality, 4. agreement, 5. complete agreement). Based on the results of the conducted survey, it is established that there is no connection between the respondents' knowledge about the care of permanent urinary catheters with regard to their level of education. Likewise, there is no difference in the answers between the age of the respondents and the knowledge about infections of indwelling urinary catheters between the respondents depending on the age. The level of education is related to the level of knowledge about the aseptic conditions of insertion of a permanent urinary catheter, that is, nurses with a high school and professional education have a higher level of knowledge about the aseptic conditions of insertion of a permanent urinary catheter than nurses with a secondary education. Some further results of the survey point to a lack of education among nurses and technicians, and it is of great importance that education is carried out continuously in order to be able to prevent new urinary tract infections in a timely manner. A highly educated nurse/technician in the health system participates in the prevention of urinary tract infections through various forms of education, work on disease prevention, education about a healthy lifestyle, hygiene of the perineal region, etc. If an infection develops after the patient is discharged from the hospital, the nurse participates in the monitoring of the patient, provides assistance with the maintenance of the urinary catheter, takes care of its timely changes, etc. Due to the very nature of the disease and the placed urinary catheter, which partially impairs physical functioning and appearance, it also impairs social functioning, and thus leads to social isolation.
