Cognitive Advances of Hospital Acquired Infection Prevention in the Department of Critical Care Medicine

Abstract

The department of critical care medicine has a high prevalence of hospital acquired infections, which are closely associated with prognosis of critically ill patients. With hospital acquired infections as the axis, the treatment of critically ill patients can be divided into three phases: management of the primary disease and support of organ function, treatment of various complications resulting from the primary disease, and control of further damage and new complications. The cycle of the last two phases may put the patient in a state of Persistent inflammation, Immunosuppression, and Catabolism Syndrome (PICS), which ultimately leads to a poor prognosis. Fine control of the above three stages to reduce the risk of hospital acquired infections is a non-negligible component of the critical care process. Therefore, how to understand, prevent and treat hospital acquired infections is a top priority in the current development of critical care medicine. This review provides a comprehensive overview of strategies for the prevention and management of hospital acquired infections in critical care, covering five areas: changing the perception of hospital acquired infections, standardizing specific prevention interventions, consolidating the theoretical basis, recognizing that hospital acquired infection prevention are treatments, and integrating treatment to quality assurance. The aim is to develop the concept of severe treatment based on the prevention and control of severe patients, reduce the risk of hospital acquired infections of severe patients and improve the quality of critical care.
