Objectives: The decision-making process for vaccination programs must be informed by cost-effectiveness analyses. This study was performed to quantify the medical expenditures for pneumococcal disease (PD) in Japan.
Methods: Surveillance data from the Japan Nosocomial Infections Surveillance program and insurance claims data were collected from community-acquired PD patients admitted to 29 hospitals in Japan. Patients with positive blood specimens were designated as having invasive PD (IPD). We estimated the medical expenditures incurred during the PD hospitalization episodes.
Results: The study sample comprised 1,358 PD patients from 28 hospitals between April 2015 and September 2017. Of these, 69 were IPD patients and 1,289 were non-IPD patients. The mean medical expenditures (standard deviation) for all PD patients, IPD patients, and non-IPD patients were estimated to be $6,610 ($13,133), $13,975 ($16,415), and $6,216 ($12,823), respectively.
Conclusion: This study is the first to quantify the medical expenditures for community-acquired PD in Japan.
