Research around Carbapenem-resistant Enterobacterales (CRE) colonization’s role in subsequent systemic infection reveals important insight into the dilemmas facing infection prevention professionals. Accorded predominantly to the bacteria’s colonization, systemic CRE infections betray conventional understanding, necessitating a careful re-examination of decolonization regimens in clinical practice. However, such insights also expose the cracks in existing knowledge, particularly around whether decolonization should indeed be recommended. The situation in China specifically underscores a need to probe the linkage between CRE colonization and ensuing systemic infection in hospitalized patients.
This study, carried out as a cohort endeavor, focussed on the analysis of clinical features of inpatients with intestinal CRE colonization. To this end, 839 cases from inpatients were scrutinized and a risk prediction model for ensuing CRE infection was built and validated. The results shed light on the critical connection between CRE colonization and subsequent systemic infections. Particularly susceptible were those patients hosted under respiratory medicine, hematology, and intensive care unit departments. Secondary infections post intestinal CRE colonization intensified the duration of hospital stays, elevated treatment costs and worse, led to higher mortality rates.
The implications of this research are profound, bearing signs to enable the early identification of patients at risk, facilitating timely interventions, and contributing significantly to the prevention and control of CRE hospital-acquired infections. The rise of CRE infections worldwide, especially in vulnerable groups further implores a review of current containment measures.
In 2013, the Centers for Disease Control and Prevention (CDC) already underscored the gravity of CRE infections, tagging it as an ’emergency’ level drug-resistant bacteria. Today, more than ever, prevention, control, and treatment of such hospital-acquired infections offer unique challenges and an escalating public health threat.
Some healthcare professionals argue that decolonization therapy for CRE carries importance in preventing adverse effects from these fatal infections. Contrarily, excessive decolonization could lead to the misuse of medical resources and excessive antibiotic use. An agreement on the precise timing and scope of such therapy has yet to be agreed upon.
This study, therefore, plays an instrumental role, shedding light on the factors correlated to secondary infection rates in patients with CRE colonization, key for early identification of highly susceptible patients. Innovative solutions like the development of a risk prediction model contribute significantly towards effective decolonization interventions and the ultimate goal of CRE hospital infection prevention and control.
