Objective: To assess the 1-year economic burden among patients hospitalized for community-acquired pneumonia (CAP) in the US.
Methods: Adult patients hospitalized for CAP between 1/2012 and 12/2016 were identified from the IQVIA hospital charge data master (CDM) linked to the IQVIA Real-World Data Adjudicated Claims – US Database (date of admission = index date). Patients had continuous enrollment 180-days pre- and 360-days post-index, and empiric antimicrobial treatment (monotherapy [EM] or combination therapy [EC]) and chest x-ray on the index date or day after. All-cause and CAP-related healthcare resource utilization and cost were assessed over the 1-year follow-up. Generalized linear models (GLM) examined adjusted total cost.
Results: The cohort comprised 1624 patients hospitalized for CAP (mean age 50.3; 52.8% female). The majority (78.2%) initiated EC, most frequently with beta-lactams + macrolides (30.4%). The index hospitalization was associated with a mean length of stay (LOS) of 5.7 days and mean cost of $17,736; 22.7% had a transfer to the intensive care unit (ICU). All-cause readmission rates at 30- and 180-days were 8.8% and 20.1%, respectively. Mean annual all-cause total cost was $61,928; one-third (33.8%, $20,954) was related to CAP. The primary cost driver was inpatient care, which accounted for more than half (56.0%) of total all-cause cost and 94.3% of total CAP-related cost. Mean total inpatient cost was significantly higher among EC versus EM patients ($37,106 versus $25,999, p = .0399). Adjusted mean total all-cause cost was $55,391.
Conclusions: Patients hospitalized for CAP incurred a significant annual economic burden, driven substantially by the high cost of hospitalizations. Additional information Acknowledgements
