Introduction: The study of the knowledge and its application in medical practice makes it possible to reflect the scale and causes of the onset and spread of nosocomial infections. Achieving a safer hospital environment is a priority in the efforts to ensure a better quality of health care.

Aim: The aim of this article is to investigate the knowledge and its application in the medical standard for the prevention and control of in-hospital infections in medical institutions, training centers for nurses and midwives (Varna, Ruse) and non-bases (Dobrich), they do not have such functions. This article studies also the precautions needed for the safety of the staff in medical establishments: information about patients who have suffered viral hepatitis B, HbsAg carrier test, immunization against viral hepatitis B, use of personal protective equipment, disinfection, sterilization.

Materials and Methods: A questionnaire for assessing the level of knowledge of the medical standard for the prevention and control of in-hospital infections in medical practice, endorsed by the Ethics Committee in Varna in November 2017, with a declaration of informed consent, was used. The methods applied included a questionnaire in addition to statistical and graphical methods.

Results: A total of 7 262 people were interviewed (volunteers with guaranteed anonimity). The questionnaire contained 25 questions, of which two were open-ended and 23 were closed-ended. The study was conducted in the period February - May 2018. We established knowledge of the medical standard for prevention and control of nosocomial infections in the group of practicing nurses and midwives in the four medical establishments with the share of those aware of it being 89.31%. The share of those having the standard  was 4.58%, 17.55% had a look at it, 27.86% have read it, and 39.31% comply with the requirements in it.

Conclusion: The knowledge of the requirements and its application in practice is at a high level in the two groups of medical institutions. Team work is placed as most important with the percentages being as follows: Dobrich 98%, University Hospital of Rousse - 100%, Rousse Oncology Center – 66.66% , Varna 87.17%. The sterilization of instruments is done in a central sterilization unit in an average of 86.92% of the cases, dry sterilizer - in 1.92%, autoclave - in 5.76%, and there is no information provided for 5.38%.
