Inclusion criteria
Inclusion criteria: 1.Collect CRKP isolates identified in our hospital from January 1, 2026 to December 31, 2026. The isolates were identified using the VITEK 2 Compact automated microbial identification and antimicrobial susceptibility testing system. CRKP was defined as Klebsiella pneumoniae isolates that were resistant to at least one carbapenem antibiotic, including imipenem, meropenem, ertapenem, or doripenem. Antimicrobial susceptibility results were interpreted according to the CLSI 2021 M100 guidelines. Resistance criteria were defined as a minimum inhibitory concentration (MIC)>=4 µg/mL for either imipenem or meropenem, or MIC >=2 µg/mL for ertapenem. 2.Patients aged>=18 years. 3.Klebsiella pneumoniae was confirmed by microbiological culture, and infection was distinguished from colonization based on clinical diagnosis. 4.Complete clinical and related data were available.
Exclusion criteria
Exclusion criteria: 1.Patients aged <18 years. 2.Patients with Klebsiella pneumoniae colonization or infections caused by other bacteria. 3.Specimens with severe contamination or duplicate isolates from the same anatomical site of the same patient. 4.Patients with missing clinical or related data.
