This study demonstrates the effectiveness of multidisciplinary approaches in controlling and treating infections caused by CRE and ESBL producers in a major tertiary healthcare setting in Egypt. The incidence rate of CRE and ESBL producers decreased after the implementation of multimodal infection control interventions. The highest resistance pattern was observed in CRE towards all tested beta-lactams and aminoglycosides, while both CRE and ESBL producers showed high susceptibility to colistin and tigecycline.
The current rise of multidrug-resistant (MDR) Gram-negative Enterobacteriaceae including the extended-spectrum beta-lactamase (ESBL)-producing organisms and carbapenem-resistant Enterobacteriaceae (CRE) has been increasingly reported worldwide, posing new challenges to health care facilities. Accordingly, we evaluated the impact of multimodal infection control interventions at one of the major tertiary healthcare settings in Egypt for the aim of combating infections by the respective pathogens. During the 6-month pre-intervention period, the incidence rate of CRE and ESBL-producing clinical cultures were 1.3 and 0.8/1000 patient days, respectively. During the post-intervention period, the incidence of CRE and ESBL producers continued to decrease, reaching 0.5 and 0.28/1000 patient days, respectively. The susceptibility rate to carbapenems among ESBL producers ranged from 91.4% (ertapenem) to 98.3% (imipenem), amikacin (93%), gentamicin (56.9%), and tobramycin (46.6%). CRE showed the highest resistance pattern toward all of the tested beta-lactams and aminoglycosides, ranging from 87.3% to 94.5%. Both CRE and ESBL producers showed a high susceptibility rate (greater than 85.5%) to colistin and tigecycline. In conclusion, our findings revealed the effectiveness of implementing multidisciplinary approaches in controlling and treating infections elicited by CRE and ESBL producers.
