Le résumé fourni par la source

On July 27th and 29th, 2022, the Prevention and Safety of Care Department at Sahloul University Hospital was alerted to an outbreak of invasive infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). The infections were reported in three departments: Post Serious Operations (PSO), Surgical Resuscitation, and Orthopedics. This case study examines the outbreak, focusing on the epidemiological investigation, environmental The teaching approach involves a systematic methodology for conducting outbreak investigations and implementing infection control strategies in a university hospital. Students will describe cases by time, person, and place, and prepare synoptic charts. They will also evaluate adherence to standard hygiene precautions and interpret data from figures and tables, leading to recommendations for corrective actions. This epidemic involved three cases of patients with intrinsic (comorbidities) and extrinsic (invasive procedures: gastrostomy, vascular catheterization, urinary catheter) risk factors. The three isolated strains had the same antibiotype characterized by resistance to all antibiotics except Fosfomycin and colistin. The environmental survey didn´t monitor any Klebsiella pneumoniae in the three patients´ environments. From the six criteria of the standard hygiene precautions, 16 observations were tested in the audit, from which (10; 62.5%) were respected in the Surgical Resuscitation department, (8; 50%) in the PSO department and (2; 12.5%) in orthopedic department. This investigation highlights the need for a proactive surveillance system and strict adherence to infection control measures to prevent the spread of CRKP.
