• Cost-Effectiveness Analysis of Fecal Immunochemical Test-based Versus Total Colonoscopy-Based Colorectal Cancer Screening in Japan: A Microsimulation Study

  Mori T., Shimohata N., Goto R.

  　概要を見る

  Objectives Colorectal cancer is a major public health concern with a high mortality rate. Fecal immunochemical tests (FIT) and total colonoscopy (TCS) are recommended screening methods; however, their cost-effectiveness varies by country. This study addressed the lack of comprehensive cost-effectiveness analyses comparing TCS with the current FIT-based screening in Japan. Methods We developed a microsimulation-based decision analytic model to compare FIT-based screening (current practice) with TCS-based screening (alternative) in a hypothetical cohort of 10 000 Japanese adults over a 60-year period. The analysis was conducted from the healthcare payer perspective, with both costs and health outcomes discounted annually by 2%. We adhered to the 2022 Consolidated Health Economic Evaluation Reporting Standards reporting guidelines and incorporated Japan-specific data on costs, participation rates, and disease progression. Results In the base-case analysis, FIT-based screening was more cost-effective than TCS-based screening. TCS-based screening also yielded fewer quality-adjusted life-years, making it the less favorable approach. Sensitivity analyses showed that FIT remained the dominant screening across most parameter variations. Conclusions In Japan, the current FIT-based colorectal cancer screening is more cost-effective than TCS-based screening. Efforts should focus on improving FIT program participation to achieve greater public health benefits, rather than transitioning to a costlier and less effective alternative.

• Organization-level factors associated with the adoption of care robots in long-term care providers: insights from a 3-year pooled cross-sectional study in Japan

  Tosaka Y., Funada S., Goto R.

  BMC Health Services Research 26 （ 1 ）  2026年12月

  　概要を見る

  Background: Care robots are expected to be useful in long-term care (LTC) settings to resolve several challenges associated with aging populations. However, their use is still limited and little is known about the factors associated with their adoption. This study aimed to identify the factors associated with the adoption of care robots, using a quantitative analysis of a large sample at the organizational level in Japan. Methods: We analyzed residential service providers using 3 years of pooled cross-sectional data from the Fact-Finding Survey on Long-term Care Work in Japan. In this survey, care robots were categorized as robots for “Transfer support,” “Mobility assistance,” “Toiletry support,” “Monitoring and Communication,” “Bathing support,” and “Support for LTC workers.” We defined “adoption of care robots” as LTC providers having adopted at least one of the care robots. To identify the characteristics of LTC providers associated with the adoption of care robots, we conducted a multivariable logistic regression comparing providers with and without care robots. Results: Of the 4,688 LTC providers, 1,250 (26.7%) adopted care robots. The characteristics of LTC providers that were found to be associated with the adoption of care robots were: information and communication technology (ICT) equipment adoption (adjusted odds ratio [aOR] 3.115, 95% confidence interval [CI] 2.453, 3.956), younger average age of care workers (aOR 0.958, 95% CI 0.945, 0.971), large number of employees (aOR 1.008, 95% CI 1.006, 1.010) and appointment of employment management supervisor (aOR 1.611, 95% CI 1.400, 1.853). The primary results were consistent across robot categories. Conclusions: Our findings suggest that care robot adoption is highly compatible with ICT equipment adoption, particularly among younger workers, and among large-scale providers and those with a high awareness of improving employment management indicated by the appointment of an employment management supervisor. To promote adoption, we suggest staff technology-literacy training (especially for senior employees), targeted financial incentives for small providers, and management-led integration of robots within employment-management improvements. This study identified the factors associated with the adoption of care robots at the organizational level and is expected to contribute to realizing the implementation of care robots.

  Reproductive Health 23 （ 1 ）  2026年12月

  　概要を見る

  Background: Women’s participation in the workforce not only promotes equal opportunity but also contributes to strengthening the social and economic development by addressing declining labour force participation rates linked to population ageing. Women have unique sexual and reproductive health needs, which can hinder their workplace participation and advancement. Therefore, understanding those needs is vital to make a work environment gender-responsive and equitable to ensure that all women can fully engage in social and economic activities. This study aims to provide evidence on the financial burden of productivity loss related to menstruation and menopause. Methods: To assess the financial impact of productivity loss due to menstruation- and menopause-related symptoms, we conducted an internet-based, cross-sectional survey in Japan in September 2022. The survey included 10,000 individuals with 4,950 women aged 25–59, of which we analysed 3,046 responses from those in paid work and with necessary information. Using the validated work productivity and activity impairment questionnaire, we assessed the financial burden of productivity loss, focusing on absenteeism and presenteeism, and estimated the national-level cost among working women aged 25 to 59. Results: Results show that approximately 7.0-8.8% of working women experienced absenteeism or reduced working hours because of the symptoms. Specifically, menstruation- and menopause-related absenteeism accounted for 2–3 days off and a reduction of 2–5 working hours in the preceding three months. Additionally, 79.7% of women reported that menstrual or menopausal symptoms impacted their work productivity. Our estimate suggests that the annual financial burden of productivity loss arising from the symptoms at the national level is approximately JPY 2,296.30 billion (USD 14.65 billion), comprising JPY 323.95 billion (USD 2.07 billion) from absenteeism and JPY 1,972.35 billion (USD 12.59 billion) from presenteeism. Discussion: This study highlights the potential of addressing menstruation- and menopause-related symptoms among working-age women in generating positive economic impacts. These findings underscore the need for workplaces to implement gender-responsive strategies that meet the sexual and reproductive health needs of women in order to ensure gender equality and women’s empowerment at workplace.

  　概要を見る

  Background: Intensive care is a cornerstone of modern health systems, yet it remains among the most resource-intensive and costly forms of care. While intensive care unit (ICU) costs represent a substantial portion of health care expenditures in many high-income countries, national-level data on ICU costs in Japan have been lacking. We aimed to estimate national ICU costs in Japan using administrative and hospital-level data, employing internationally comparable methods. Methods: We conducted a nationwide retrospective cohort study using the Diagnosis Procedure Combination Study Group database and the Hospital Bed Function Report during fiscal years 2018–2022. ICU costs were estimated using a bottom-up costing approach aligned with the method used in major international studies, and focused on certified adult and pediatric ICUs. Macroeconomic impact, temporal trends, and regional variation were assessed. We also analyzed the cost of intermediate care units (IMCU) and IMCU–ICU ratio. Results: A total of 1,453,929 ICU patients were identified in the DPC Study Group database from 2018 to 2022, which covers 68.2% of all ICU beds in Japan. The mean ICU cost per patient-day was ¥197,277 (approximately $1,793 USD), and the estimated national ICU cost over the 2018–2022 period was ¥1,785 billion (mean ¥357 billion per year). This represented 0.065% of nominal gross domestic product (GDP), 0.56% of total health expenditures, 1.42% of hospital expenditures, and 2.17% of inpatient expenditures. The macroeconomic impact of ICU care was stable from 2018 to 2022. The proportion of ICU costs relative to nominal GDP, total health expenditures, and hospital expenditures in Japan was substantially lower than in the United States, Canada, and Australia. Regional variation was pronounced, with up to a 7.5-fold difference across prefectures. The estimated national IMCU cost over the 2018–2022 period was ¥2,838 billion (mean ¥568 billion per year), approximately 1.5 times greater than ICU cost (IMCU–ICU ratio is approximately 1.59). Conclusions: This study provides the first comprehensive national estimates of ICU costs in Japan using internationally aligned methods. These findings indicate lower ICU spending in Japan than in other high-income countries.

  　概要を見る

  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.

  適正な医療資源の配分のためのエビデンスを提供することを目的として行われる医療経済評価では,異なった領域の介入の比較を容易にするため,アウトカム指標を質調整生存年(Quality-adjusted life year:QALY)とすることが原則とされている.QALYは生存期間にQOL(Quality of life)を0から1の値に換算したQOL値を重み付けして得られる.QALYにはその国の人々の選好による重みづけが反映されることが望ましいという観点から,QOL値は国内の調査結果を優先的に使用することが推奨されているが,以前から日本人のデータが乏しいことが指摘されていた.近年成人ではその蓄積が進みつつあるが,小児においてはその測定に多くの課題があり,日本ではほぼ行われていないのが現状である.医療経済評価でQOL値測定に用いられる尺度は選好に基づく尺度(Preference-based measure:PBM)である.PBMによってQOL値を得る過程は,評価したい健康状態の「測定」と「価値づけ」に分けられる.これを一度に行うものを直接法,別々に行うものを間接法と呼ぶ.直接法には評点尺度法,時間得失法,基準的賭け法があるが,小児では実施可能性,信頼性,妥当性はまだ十分に検討されていない.成人も含め一般的に現在主流となっている間接法では,multi attribute utility instruments(MAUIs)と呼ばれる尺度を用い,実際にその健康状態にある人(患者)に自らの健康について質問票に記入してもらった後,換算表を用いてQOL値を算出する.一般的に成人を対象に開発されたMAUIsは,小児で使用するにあたって質問の記述の仕方や内容が適していない,さらに換算表が成人の健康についての価値付けになっているなどの問題があり,小児には小児用のMAUIsの使用が望ましいとされる.近年小児用のMAUIsの開発が進んできたが,各国での翻訳や換算表の有無により,どの国でもこれらが使用できるわけではなく,3歳以下の年少児では使用できるものは現在ない.また,どの領域をどのように評価するべきか,誰が記入するべきかなどの「測定」に関する課題,換算表の作成にあたって誰の選好をどの視点を使用して明らかにし,反映するべきなのかという「価値付け」の課題があり,現在あるMAUIsが十分に小児の健康関連QOLをとらえられていない可能性もある.日本ではこれまで小児の使用を想定したMAUIsがなかったが,最近EuroQol 5-dimension Youth version(EQ-5D-Y)日本語版とその換算表が発表され,今後日本人小児のデータの蓄積が期待される.小児のQOL値の測定と解釈にあたっては,その課題や限界を十分に理解しておく必要がある.(著者抄録)
