Insights into the Clinical Management of Carbapenem-Resistant Gram-Negative Infections: An Italian Retrospective Clinical Chart Review.

There is a lack of consensus regarding management of infections with carbapenem- resistant Gram-negative (CR-GN) pathogens. This study comprised a medical chart review to assess patient management in a high CR prevalence setting. Data was collated retrospectively from medical records of patients hospitalized between November 1, 2015 and October 31, 2016. Of 29 patients, 66% had respiratory tract infections. Median duration of hospitalization was 28 days and ~50% of patients were admitted to the intensive care unit, with 77% remaining for >2 weeks. Median time to obtain respiratory culture results was 5 days. Isolation of patients with diagnosed CR-GN infection took ≥5 days in >50% of patients. A majority (76%) of patients received ≥1 antibiotic before providing a specimen for culture; a total of 17 antibiotic treatments were used. Overall, 72% of patients, and 68% of those with respiratory infections, were discharged alive; 38% were discharged without further antibiotics. The difficulties in achieving effective management in patients with CR-GN infections are largely due to complex co-morbidities, a history of prior antibiotic treatment, and multiple referrals across health care facilities.
