Description
Summary:INTRODUCTIONInfections caused by carbapenemase-producing Enterobacteriaceae (CPE) are dramatically increasing worldwide, with an important impact on surgical patients. Our aim was to assess the clinical profile, outcomes, treatment, mortality and costs of CPE-related surgical site infection (SSI) in patients with abdominal surgery. METHODSReview of CPE-related SSI in patients with abdominal surgery from January 2013 to December 2018. Patient factors and interventions present previously to the SSI identification were recorded, and a mortality analysis was also performed in patients with abdominal surgery and CPE-related organ/space SSI. RESULTSFifty patients were included: superficial incisional SSI 50%, deep incisional SSI 28%, organ/space SSI (or intra-abdominal infection) 70%. Klebsiella pneumoniae OXA-48 was present in 84%, and the most frequent were colorectal surgery (40%) and pancreatic surgery (20%). The antimicrobial susceptibility was: ceftazidime-avibactam 100%, amikacin 91.7%, tigecycline 89.1%, colistin 70.8%, meropenem 62.8%, imipenem 52.1%. An appropriate definitive antimicrobial treatment was administered in 86%, using a combined scheme in 76%. Global 30-day mortality rate for intra-abdominal infection was 20%, and mortality-related factors were: solid tumour (P=.009), solid metastasis (P=.009), septic shock (P=.02), blood transfusions (P=.03). Median global stay was 45 (IQR 26-67) days. Median global cost of hospitalization was €29,946 (IQR 15,405-47,749). CONCLUSIONSThe clinical profile of patients with CPE-related SSI associates several comorbidities, interventions, prolonged stay and elevated costs. Mortality-related factors in intra-abdominal infection are solid tumour, metastasis, septic shock or blood transfusions.
