Ceftaroline fosamil treatment patterns and outcomes in adults with community-acquired pneumonia: a real-world...

This multicentre, observational, retrospective chart review study assessed ceftaroline fosamil treatment patterns and outcomes in adults hospitalized with community-acquired pneumonia (CAP) in usual care settings.

Anonymized patient data were extracted from hospital records of adults with CAP who received ≥4 consecutive IV ceftaroline fosamil doses at sites in Brazil, Colombia, France, Greece, Italy, Russia and Spain.

The dataset included 185 patients (58.9% male; mean age 62.2 years), of whom 128 (69.2%) had severe CAP defined by CURB-65, PSI/PORT score or physician judgement. Streptococcus pneumoniae (n = 44; 23.8%) and Staphylococcus aureus [MSSA (n = 15) and MRSA (n = 14)] were the most frequently identified pathogens. Clinical response occurred in 151 (81.6%) patients overall, and in 104 (81.3%) severe CAP patients. Response within ≤4 and >4 days occurred in 79 (42.7%) and 62 (33.5%) patients (unknown, n = 10), respectively. Twenty (10.8%) patients required readmission within 30 days. Thirty-day all-cause mortality rates were 9.7% (n = 18) overall and 10.2% (n = 13) in severe CAP. In sensitivity analysis using ICU admission as a more objective marker of severe CAP (n = 75), clinical response and 30 day mortality occurred in 57 (76.0%) and 10 (13.3%) patients, respectively. Overall, clinical response to ceftaroline fosamil was associated with >60% shorter length of ICU stay (3.6 versus 9.2 days), and >30% lower hospital costs ($8449 versus $12 559) versus non-responders.

Ceftaroline fosamil was effective in treating adults with CAP, including severe CAP, in Europe and Latin America. Clinical response to ceftaroline fosamil was associated with reductions in healthcare resource use compared with non-responders.
