Nosocomial infections are a major burden on the health system of the whole world. We define them as infections that occur 48 hours after the start of the hospital stay or 14 days after discharge from the hospital, and are caused by multiresistant microorganisms. Intrahospital or nosocomial infections, as a result of their occurrence, cause an increase in mortality and treatment costs of patients and prolong the length of stay in the hospital. Intrahospital infections also include urinary tract infections associated with urinary catheters. Numerous guidelines have been issued as well as preventive measures in order to prevent frequent and costly healthcare infections, considering the clinical and financial consequences of u/s catheterization infections. In order to increase the quality of health care, it is necessary to constantly educate the medical staff and spread new knowledge. Precisely for this purpose, a cross-sectional survey was conducted in the period from April 6 to May 9, 2022, among nurses and technicians employed in the profession through an online questionnaire in the form of a Google form, by solving which the respondents agree to the research, and their participation is anonymous. The questionnaire consisted of 3 parts. In the first part, sociodemographic data were examined, then knowledge was examined through questions about indications for catheter insertion and measures to prevent urinary tract infections related to catheters. In the last part, attitudes about the prevention of infections of the same name were examined. The aim of the study was to examine the knowledge and attitudes of nurses/technicians about catheter-related urinary tract infections. 143 respondents, aged between 21 and 63, took part in the research. The most frequent places of work of the respondents were the intensive care unit, the surgery unit, the internal medicine unit and the emergency medicine unit. The largest share of participants was female (94.60%), having completed undergraduate studies in nursing (48.30%). In terms of seniority, respondents most often had 10 or more years of seniority (62.20%). During the previous month, the largest number of participants inserted a urinary catheter once or never (42.00%). Basically, all participants were familiar with the protocol for the care or prevention of catheter-related urinary tract infection (86.70%). Regarding additional workplace education about catheter-related urinary tract infections, the majority of participants stated that they did not receive additional education about the same (72.00%). In conclusion, the knowledge and attitudes of nurses and technicians play an important role in the prevention of catheter-related urinary tract infections, which is why the education of medical personnel is the most important link in the chain of prevention.
