ABSTRACT: Background: To drill down into why per capita health expenditures vary
between the US and Japan, this exploratory

inpatients for two procedures in an academic hospital in the US, and one in
Japan. Methods: Detailed analysis of the amount reimbursed and services
delivered was made from claims data for 449 acute myocardial infarction treated
with coronary stents placed by percutaneous coronary intervention (PCI) and
115 heart valve dysfunction with heart valve replacement (HVR) cases in
Johns Hopkins Hospital (JHH) Baltimore, Maryland, and 34 PCI and 21 HVR cases
in Keio University Hospital (KUH), Tokyo. Results: After making appropriate adjustments, the reimbursed amount per discharge at JHH was significantly higher (Wilcoxon ranksum test, p Conclusion: Detailed analysis of the reimbursed amount and the
utilization of services are needed to understand
international variations in healthcare spending.
