    ISSN  00316903

    　View Summary

    <p>The innovation patterns and institutional environments of software as a medical device (SaMD) were empirically, comparatively, and institutionally analyzed as SaMD is attracting attention as innovative medical technology. Data were collected on SaMD products approved by the U.S. Food and Drug Administration (FDA) and medical providers (<i>n</i>=581 and 268, respectively). The relationships among SaMD use, the interaction of SaMD with existing medical devices, and company characteristics were structurally evaluated. The use of the current SaMDs as highly concentrated in the medical image processing field, with emerging information and communication technology companies producing many products. The relationship between SaMDs and hardware-type medical devices varied with their use purpose, based on which an innovation regime map for SaMDs was constructed. Next, the differences in reimbursement systems in Japan, the U.S., and Europe were comparatively analyzed, considering the policy implications for high-uncertainty technologies, such as SaMD and orphan drugs. We specifically focused on the cost-effectiveness-oriented reimbursement decision in Europe, the approval-for-reimbursement structure in Japan, and the range of individual decisions by payers in the United States. We summarized the actual state of price setting and payment models in each region (<i>e.g.</i>, performance-based payments, price caps, and rebates). A framework for risk allocation between manufacturers and insurers is required when the value of medical technology is uncertain, suggesting a need for flexible and data-linked evaluations in future system designs.</p>

  • Low-cost, high-volume healthcare services contribute the most to low-value care spending in Japan

    Miyawaki A., Mafi J.N., Fukui T., Kimura Y., Kobayashi D., Odawara S., Abe K., Goto R., Tsugawa Y.

    Health Affairs Scholar 3 ( 12 )  2025.12

    　View Summary

    Introduction High-income countries face the urgent task of reducing healthcare spending incurred by low-value care. However, evidence is limited as to whether high-cost or low-cost low-value care services contribute more to total unnecessary healthcare spending, especially outside the United States. Methods Using a claims database covering all age groups in Japan from April 2022 to March 2023 (approximately 2 million beneficiaries, or 2% of the total population), we examined 52 low-value care services using two versions of claims-based measures with different sensitivities and specificities (narrower and broader definitions). Results We identified 3.1 million (narrower) to 3.7 million (broader) episodes of low-value care services, accounting for 42.6-67.2 million USD, or 0.7%-1.0% of total healthcare spending. In the narrower definition, lower-cost services (<80 USD per service) contributed to virtually all episodes of low-value care and 67% of total unnecessary healthcare spending—far exceeding the 33% attributed to the higher-cost services (≥80 USD). Conclusion This finding suggests that compared with focusing solely on higher-cost low-value care services, targeting the reduction of frequently performed, lower-cost low-value care services may be a more effective and efficient strategy for reducing wasteful spending.

  • Difference in time and risk preferences: physicians and general population across genders

    Kasahara S., Kato H., Goto R.

    Health Economics Review 15 ( 1 )  2025.12

    　View Summary

    Background: The alignment of preferences between physicians and patients can cause variations in treatment decision-making, thereby affecting health outcomes. However, research on the differences in preferences between physicians and the general population is scarce. This study examines the risk and time preferences of physicians compared with those of the general population, exploring the influence of gender concordance on health outcomes and decision-making in healthcare. Methods: We conducted an online field experiment in October and November 2022 in Japan and analyzed the responses of 469 individuals, including physicians and the general population. The survey was stratified by age and gender to align with the demographics of physicians nationally. Participants’ preferences were measured across the health and monetary domains by using a modified multiple price list test format. Results: The findings revealed that physicians tended to be more risk-averse than the general population in the health and monetary domains, although no statistically significant differences were observed. Physicians were found to be statistically significantly future-oriented, particularly regarding their significant health or monetary gains. Furthermore, while the female general population was more risk-averse in both domains, a gender difference in the physician group was observed only in the monetary domain. Conclusion: The results affirm that preference differences between physicians and the general population exist in Japan and clarify the unique preference traits of female physicians.

  • The intergenerational health effects of child marriage bans

    Le D.D., Molina T., Ibuka Y., Goto R.

    Journal of Health Economics 104 2025.12

    ISSN  01676296

    　View Summary

    Using data from 17 countries, we investigate the effects of child marriage bans on child mortality in the next generation. We use within-country variation in mothers’ exposure to the ban across cohorts and in “treatment intensity,” calculated based on region-level child marriage prevalence and marriage age prior to the ban. We find that child marriage bans reduced under-5 mortality, with an effect of 19.7 percent corresponding to a one standard deviation change in treatment intensity. Increases in age at first marriage and first birth, which may have led to improved health-related decisions around the time of birth, appear to be the main drivers of the mortality reductions documented.

  • Cost-effectiveness comparison between blood biomarkers and conventional tests in Alzheimer's disease diagnosis

    Noda K., Lim Y., Goto R., Sengoku S., Kodama K.

    Drug Discovery Today (Drug Discovery Today)  29 ( 3 )  2024.03

    ISSN  13596446

    　View Summary

    Dementia management has evolved with drugs such as lecanemab, shifting management from palliative care to early diagnosis and intervention. However, the administration of these drugs presents challenges owing to the invasiveness, high cost and limited availability of amyloid-PET and cerebrospinal fluid tests for guiding drug administration. Our manuscript explores the potential of less invasive blood biomarkers as a diagnostic method, with a cost-effectiveness analysis and a comparison with traditional tests. Our findings suggest that blood biomarkers are a cost-effective alternative, but with lower accuracy, indicating the need for multiple specific biomarkers for precision. This underscores the importance of future research on new blood biomarkers and their clinical efficacy.

  • Health-related quality of life assessment in children for economic evaluation

    HONDA Kimiko, SHIROIWA Takeru, GOTO Rei, FUKUDA Takashi

    Journal of the National Institute of Public Health (National Institute of Public Health)  71 ( 3 ) 264 - 275 2022.08

    ISSN  1347-6459

    　View Summary

    <p>The use of quality-adjusted life year (QALY) as a measure of benefit is recommended in economic evaluation, which aims to provide evidence for the appropriate allocation of health care resources. This allows for an easier comparison of interventions' effects in different fields. A QALY value is calculated by weighting the life years (LYs) by the quality of life (QOL) score, which is determined by preference-based measure (PBM) and converted from 0 to 1. The QOL score should be obtained through domestic surveys because it reflects the value in the country's general population. In Japan, the data of the QOL scores for adults have been accumulated in recent years. However, few studies for children have been conducted due to various issues in evaluating pediatric health-related QOL (HRQOL). The PBM process for obtaining the QOL score can be divided into “measurement” and “valuation” of the health state to be evaluated. This process is implemented at once in direct methods, whereas it is carried out separately in indirect methods. Direct methods include the rating scale, the time trade-off, and the standard gamble, but children's feasibility, reliability, and validity must be thoroughly investigated. In indirect methods, which is currently the mainstream in general, multi-attribute utility instruments (MAUIs) are used, consisting of a questionnaire to measure the health state and a value set to value the measured health state. However, most MAUIs are designed for adult use and are not suitable for pediatric use because the questions are inappropriate, and the value set is intended to value adult health. In recent years, some MAUIs for pediatric use have been developed. Nevertheless, due to translations and the value set, these are not available in all countries. Additionally, there are no existing MAUIs available for children aged 3 years. Furthermore, issues concerning “measurement,” such as which domains should be assessed and how, and by whom, and issues concerning “valuation,” such as whose preferences should be reflected in developing the value set, and which perspectives should be used, remain. There have been no MAUIs for pediatric use in Japan, but the Japanese version of the EuroQol 5-dimension Youth version (EQ-5D-Y) and its value set have recently been published. It is necessary to fully understand the challenges and limitations in measuring and interpreting the QOL score in children.</p>
