The 1-year economic burden of community-acquired pneumonia (CAP) initially managed in the outpatient setting in the USA

Abstract

Aim: To assess the annual economic burden of community-acquired pneumonia (CAP) initially managed in the outpatient setting. Patients & methods: Patients with an outpatient diagnosis of CAP between January 2012 and December 2016 were identified from the IQVIA (Danbury, CT & Durham, NC, USA) Real-World Data Adjudicated Claims - US Database. All-cause and CAP-related healthcare resource utilization and costs were assessed over the 1-year follow-up. Generalized linear model examined adjusted total cost. Results: Among 256,916 patients with outpatient CAP, a tenth (10.6%) had ≥1 hospitalization and, of these, 18.7% had ≥1 CAP-related hospitalization. The mean total cost per patient was US$14,372; 10.9% was CAP-related and 26.1% was due to inpatient care. The adjusted mean total all-cause cost was US$13,788. Conclusion: Patients with outpatient CAP incurred a substantial annual economic burden.
