Value-based reimbursement under the inpatient prospective payment system in Japan: a review of Japan's diagnosis procedure combination/per-diem payment system.

Aim: The aim of this study is to review the influence of functional evaluation coefficient (FEC) II adjustments on reimbursement for hospitals in Japan operating under the diagnosis procedure combination/per-diem payment (DPC/PDPS) system.

Methods: Publicly available information was used to describe the FEC II adjustment system and to consider its influence on reimbursement for fiscal years (FY) 2018, 2020, and 2022. Moreover, descriptive statistics and multivariate regression analysis were used to consider how the adjustment differed based on hospital and treatment-related characteristics in FY 2022.

A pragmatic review of cost-effectiveness evaluations of reimbursed medical devices conducted for Japan.

Aims: The aim of this study is to examine the characteristics and quality of economic evaluations for reimbursed medical devices in Japan.

Materials And Methods: A pragmatic review of cost-effectiveness evaluations (CEA) and other economic evaluations for medical devices reimbursed in Japan published between January 2010 and December 2023 was conducted using the PubMed (Medline), Japan Medical Abstracts Society (ICHUSHI Web), and the Cost-Effectiveness Analysis Registry of the Tufts Medical Center databases-as well as Google Scholar. Evaluations for devices assessed under the health technology assessment system in Japan were also reviewed.

Analysis of factors associated with premiums for reimbursed medical devices in Japan.

Aims: The aim of this study is to examine factors that relate to receipt of a reimbursement premium in Japan, which is defined as an increase in the initially calculated reimbursement price based on certain criteria, or an increase in the operating profit ratio.

Materials And Methods: Reimbursement submissions and decisions for newly reimbursed medical devices in Japan from fiscal year (FY) 2015 to FY 2023 were reviewed to consider their characteristics. Moreover, the relationship between reimbursement submission characteristics, as well as other characteristics such as regulatory submission category, risk class, location of the manufacturer headquarters, etc.

Characterization of 37 enological tannins using a multiple technique approach: Linear sweep voltammetry as a rapid method both for classification and determination of antioxidant properties.

In this work, 37 enological tannins of different classes were studied to investigate whether linear sweep voltammetry (LSV) could be a method to determine the family of a sample and its antioxidant capacity. A "wholistic" approach was used, combining LSV data with nuclear magnetic resonance (NMR), polyphenol quantification (Folin-Ciocalteu method and gravimetric analysis), antiradical activity (DPPH assay), and reducing capacity (FRAP assay). Voltammetric data were processed with statistical techniques and the results show the clustering of tannins in three different classes: ellagitannins, gallotannins, and condensed tannins.
