Abstract:
Objective To investigate the cause of a suspected outbreak of carbapenem-resistant Klebsiella pneumoniae infection(CRKP)in the neurological ICU,to find out the reason for infection and the way of transmission to provide evidence for the prevention and control of nosocomial infection.Methods Four patients with CRKP infection in the department of neurological ICU of a hospital from Au-gust 4 to August 20,2020 were investigated epidemiologically and environmental hygiene monitoring of the ward was carried out.Compre-hensive measures were taken to control the outbreak.Results All four CRKP infection cases were hospital-acquired,and the isolated strains showed consistent drug susceptibility test results,indicating they were the same clone.Environmental hygiene monitoring revealed the presence of the same clone in samples from patient bedside items,suction devices,oxygen therapy equipment,and personal belongings of healthcare workers.After implementing comprehensive corrective measures,no new cases of CRKP infection occurred,and subsequent surface sampling did not isolate any CRKP strains.Conclusion Environmental surface contamination in the neurointensive care unit and inadequate disinfection procedures were likely the main causes of the suspected outbreak of CRKP infection.Prompt identification of the outbreak,activation of emergency response plans,and implementation of corrective measures are crucial for controlling the outbreak of multidrug-resistant bacterial infections in hospitals.After adopting comprehensive measures,there were no new CRKP infection cases.
