Background. The clinical response to ertapenem in community-acquired pneumonia (CAP) at the setting of routine hospital practice has been scarcely evaluated.
Methods. We retrospectively compared CAP cases treated with ertapenem or with other standard antimicrobials (controls) at a tertiary 1,434-bed center from 2005 to 2014.
Results. Out of 6,145 patients hospitalized with CAP, 64 (1%) ertapenem-treated and 128 controls were studied (PSI IV-V 72%, mean age 73 years.). A significant higher proportion of bedridden patients (41% vs. 21%), residence in nursing homes (19% vs. 7%), previous use of antibiotics (39% vs. 29%) and necrotizing (13% vs. 1%) or complicated (36% vs. 19%) pneumonia, was observed in the ertapenem vs. non-ertapenem patients. Initial treatment with ertapenem was independently associated with an earlier resolution of signs of infection. In patients aged 65 or older the independent risks factors for mortality were: PSI score (7.0, 95%CI 1.8-27.7), bedridden status (4.6, 95%CI 1.1-20.9) and Health Care Associated Pneumonia (HCAP) (4.6, 95%CI 1.3-16.5). First-line treatment with ertapenem was an independent protector factor in this subgroup of patients (0.1, 95%CI 0.1-0.7).
Conclusions. Ertapenem showed a superior clinical response in frail elderly patients with complicated community-acquired pneumonia, and it may be considered as a first-line therapeutic regimen in this setting.
