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

    Kasahara S., Kato H., Goto R.

    Health Economics Review 15 ( 1 )  2025年12月

     概要を見る

    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.

  • Primary Care Physician Characteristics and Low-Value Care Provision in Japan

    Miyawaki A., Mafi J.N., Abe K., Klomhaus A., Goto R., Kitajima K., Sato D., Tsugawa Y.

    JAMA Health Forum 6 ( 6 )  2025年06月

     概要を見る

    Importance: Evidence is limited regarding the physician characteristics associated with the provision of low-value services in primary care, especially outside of the US. Objective: To measure physician-level use of 10 low-value care services that provide no net clinical benefit and to investigate the characteristics of primary care physicians who frequently provide low-value care in Japan. Design, Setting, and Participants: This cross-sectional analysis used a nationwide electronic health record database linked with claims data in Japan to assess visits by adult patients (age ≥18 years) to a solo-practice primary care physician from October 1, 2022, through September 30, 2023. Data analysis was performed from June 2024 to February 2025. Main Outcomes and Measures: Multivariable-adjusted composite rate of low-value care services delivered per 100 patients per year, aggregated across 10 low-value measures, after accounting for case mix and other characteristics. Results: Among 2542630 patients (mean [SD] age, 51.6 [19.8] years; 58.2% female) treated by 1019 primary care physicians (mean [SD] age 56.4 [10.2] years; 90.4% male), 436317 low-value care services were identified (17.2 cases per 100 patients overall). Nearly half of these low-value care services were provided by 10% of physicians. After accounting for patient case mix, older physicians (age ≥60 years) delivered 2.1 per 100 patients (95% CI, 1.0-3.3) more low-value care services than those younger than 40 years; not board-certified physicians delivered 0.8 per 100 patients (95% CI, 0.2-1.5) more than general internal medicine board-certified physicians; physicians with higher patient volumes delivered 2.3 per 100 patients (95% CI, 1.5-3.2) more than those with low patient volumes; and physicians practicing in Western Japan delivered 1.0 per 100 patients (95% CI, 0.5-1.5) more than those in Eastern Japan. Conclusions and Relevance: The findings of this cross-sectional analysis suggest that low-value care services were common and concentrated among a small number of primary care physicians in Japan, with older physicians and not board-certified physicians being more likely to provide low-value care. Policy interventions targeting at a small number of certain types of physicians providing large quantities of low-value care may be more effective and efficient than those targeting all physicians uniformly.

     概要を見る

    Background: Surgical-site antisepsis is used to prevent surgical-site infections (SSIs). Although several guidelines have indicated the efficacy of antiseptics, such as chlorhexidine, povidone-iodine, and olanexidine, in reducing the SSI rate, an optimal recommendation is still not established. The aim of this study was to evaluate the efficacy of aqueous olanexidine compared with chlorhexidine-alcohol as the optimal antiseptic for preventing SSI in clean-contaminated surgery. Methods: This multicentre randomized trial for surgical skin antisepsis in clean-contaminated gastrointestinal and hepatobiliary-pancreatic surgeries in five hospitals evaluated the efficacy of olanexidine and chlorhexidine-alcohol. The primary endpoint was 30-day SSI. Secondary outcomes included the occurrence of SSI types, intervention-related toxicity, and reoperation caused by SSI. Results: Overall, 700 patients from five institutions underwent randomization; 347 received olanexidine and 345 received chlorhexidine-alcohol in the full analysis set. The 30-day SSI rate was 12.4% (43 of 347) in the olanexidine group and 13.6% (47 of 345) in the chlorhexidine-alcohol group (adjusted risk ratio (aRR) 0.911 (95% c.i. 0.625 to 1.327); P = 0.626). No significant differences were observed between the groups regarding the secondary outcomes, including the occurrence of superficial incisional SSI, deep incisional SSI, organ/space SSI, and reoperation caused by SSI. Overall adverse effects were seen in two patients (0.58%) in the olanexidine group and in three patients (0.87%) in the chlorhexidine-alcohol group (aRR 0.663 (95% c.i. 0.111 to 3.951)). Conclusion: Olanexidine did not significantly reduce the occurrence of overall SSI compared with chlorhexidine-alcohol. Nevertheless, these findings provide valuable insights for developing novel surgical SSI management protocols.

     概要を見る

    Objectives: We examined shifts in labor productivity and their economic ramifications among adult patients with long COVID in Japan. Methods: A total of 396 patients were categorized into three groups based on symptom progression: non-long COVID, long COVID recovered, and long COVID persistent. Patient-reported outcomes were assessed at three time intervals: 3, 6, and 12 months after COVID-19 diagnosis. Labor productivity was gauged through presenteeism and absenteeism, measured using the World Health Organization Health and Work Performance Questionnaire. Results: Long COVID was observed in 52.7% of patients, and 29.3% of all the patients continued to experience long COVID symptoms 1 year after diagnosis. At all three time points (3, 6, and 12 months after diagnosis), the long COVID persistent group showed a statistically significant difference in absolute presenteeism compared with the non-long COVID and long COVID recovered groups (P <0.01). Economic loss owing to decrease in labor productivity was calculated as $21,659 per year in the long COVID persistent group and $9008 per year in the long COVID recovered group (P <0.01). Conclusion: The study's results revealed a notable decline in labor productivity over time, underscoring the importance of early detection and intervention to mitigate the socio-economic repercussions of long COVID, in addition to its health implications.

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

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

     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.

  • 医療経済評価における小児のQOL値測定法とその課題

    本多 貴実子, 白岩 健, 後藤 励, 福田 敬

    保健医療科学 (国立保健医療科学院)  71 ( 3 ) 264 - 275 2022年08月

    ISSN  1347-6459

     概要を見る

    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)
