About the U.S. Social Insurance Administration's (CMS) ACO New Model "LEAD" (March 13, 2026)
In December 2025, the Innovation Center of the U.S. Social Security Administration (CMS), which oversees Medicare, unveiled a new model for Accountable Care Organizations (ACOs), the Long-term Enhanced ACO Design (LEAD) model. Milliman was one of the first to introduce and announce the mechanism as a white paper. It will be the link below.
https://www.milliman.com/en/insight/cms-aco-lead-medicare-medicaid-integration-opportunity
ACOs are institutionalized as part of Obamacare in 2010 and are centered on U.S. family physicians, who are paid by CMS as bonuses if they can reduce health care costs below the benchmark without compromising the quality of care for the group of insured people they are responsible for. LEAD is a dual eligible. It is known that these people are a large part of the health care expenditure. The ACO model for such high-risk groups is likely to have a variety of intervention methods. The white paper also highlights LEAD as an experimental model for Medicare and Medicaid integration: payment integration, care integration, and data integration.
Regarding ACOs, it seems to give various hints when thinking about Japan's medical insurance system.

Milliman Newsletter Published a paper on the ROI of Nippon Life and Specific Health Guidance （March 11, 2026）
We have published the following papers co-authored with Nippon Life Insurance and Dr. Igarashi of the University of Tokyo. The content verified whether Japan's specific health guidance has a return on investment (ROI) from the perspective of reducing medical costs using real-world data derived from the health insurance association owned by Nippon Life.
The results showed that in motivational and active support, ROIs were 3.90 and 1.36, respectively, both above 1, suggesting that they were economically beneficial.

Milliman Newsletter: Burden of Depression and Alzheimer's Disease Using a General Equilibrium Model (December 16, 2025)
When we think of disease burden, we tend to think of medical expenses. Certainly, from the insurer's point of view, medical expenses (the part of insurance benefits excluding co-payments) are recognized as "burdens". However, from the standpoint of society, if "burden" is defined as something that reduces GDP, medical expenses do not necessarily fall under the burden of disease. This is because medical expenses are the income of doctors, medical institutions, and medical workers, so they are only income transfers from a macroeconomic point of view, and do not reduce GDP itself.
In order to assess the disease burden of society as a whole, it is necessary to distinguish between such income transfer and real production losses. For this purpose, the Computable General Equilibrium (CGE) model is effective. The CGE model quantifies the pure macroeconomic loss remaining in GDP based on the theorem that "health care costs do not reduce GDP, while inability to work and productivity decline due to disease reduce GDP."
Furthermore, the CGE model is characterized by its endogenous view of the impact of the CGE model on the entire economy, rather than the direct impact of productivity decline on individuals and specific industries. Specifically, the interdependence and general equilibrium effect between economic agents is considered, in which a decrease in the supply of labor affects wages, consumption, investment and inter-industrial transactions, which in turn feed back into productive activity. As a result, the impact of disease is evaluated not just as a build-up of productivity losses, but as macroeconomic losses, including synergies and multiplier effects on the economy as a whole.
The analysis based on this framework revealed the following points (Key findings):

Milliman Newsletter – The Position of NDB in Japan’s Policy Hierarchy and Its Strategic Role in Evidence-Based Policy Making (December 12, 2025)
We introduced our independent research using the Ministry of Health, Labour and Welfare’s National Database (NDBβ) in the July 1 issue of Social Insurance Weekly. This time, we reviewed major national policy documents related to the utilization of NDB, clarified its multi-layered and cross-cutting position within Japan’s policy framework, and examined the strategic role of evidence-based policy making (EBPM) leveraging NDB as a core information infrastructure in addressing challenges in Japan’s healthcare and social security systems.
Our paper on this topic was published in the December 11 issue of Social Insurance Weekly. If you are interested, please contact us at the address below.

Milliman Newsletter Paper "NDB Update: From an Actuary's Perspective" Published in JARIP BULLETIN (Nov. 20, 2025)
We are pleased to announce that the paper "Latest Developments in the NDB: An Actuary's Perspective" has been published in Volume 9, Issue 1 of the JARIP BULLETIN (Japan Association for Risk and Insurance Practice).
The National Database (officially named the "Anonymous Medical Insurance and Related Information Database," "NDB") is a database unique in the world, yet its recognition among insurance companies remains relatively low. Milliman has analyzed the NDB relatively early on, primarily in projects with pharmaceutical companies as clients. Recently, the situation has significantly improved, especially with the start of cloud-based provision.

Milliman Newsletter: Published a paper simulating the waiting period for lecanemab treatment.
Lecanemab is a disease-modifying drug for Alzheimer's disease. We are pleased to announce the publication of a paper co-authored by Milliman, which evaluated through simulation how the diagnostic process required for lecanemab treatment would change in Japan if a blood biomarker (BBM) test were introduced.

―Summary―
This project was conducted with Eisai as the client.
First, we investigated the Willingness-to-pay (WTP) for the test. We then estimated the total cost of the test, including non-monetary costs (waiting time, travel time, etc.). We assumed individuals would join the testing queue only if their WTP exceeded these total costs. Longer queues increase non-monetary costs and reduce the number of people willing to wait, necessitating dynamic simulation. Additionally, since the distance to hospitals with specialists and transportation costs vary by region, we conducted simulations using nationwide geographic data.
The results showed that introducing BBM reduces waiting times.

A Reflection Paper on Real-World Evidence Issued by EMA (October 20, 2025)
It’s a bit belated, but in March 2025 the European Medicines Agency (EMA) issued a Reflection Paper on the generation of real-world evidence from non-interventional studies (i.e., observational research rather than clinical trials), which I’d like to introduce.
First, a “Reflection Paper” is a document issued by the EMA to share its current thinking as a regulator on a particular area or new methodology. Unlike a guideline, it is not legally binding. However, in practice it functions as a de facto norm, because it is difficult for applicants (e.g., pharmaceutical companies) to ignore the views expressed in a Reflection Paper when preparing regulatory submissions.
The main structure of the paper is as follows:
Below are several points I found particularly interesting.
First, the study’s primary objective must be clearly identified as descriptive or causal at the outset. Descriptive objectives encompass studies that characterize prevalence, incidence, treatment patterns, healthcare resource utilization, and safety-signal detection—aimed mainly at understanding “what is happening.” Causal objectives evaluate whether a treatment is effective and safe, or how it compares with an alternative, with the goal of estimating treatment effects; this requires appropriate design choices, confounding control, and bias mitigation. ISPOR guidelines likewise propose first distinguishing Exploratory Treatment Effectiveness Studies from Hypothesis-Evaluating Treatment Effectiveness (HETE) Studies. In practice, the complexity of analyses differs markedly between these two types.
Next, regarding the active comparator. When comparing a treatment, the paper advises choosing as the control not “no treatment” or an “untreated” group, but rather another clinically appropriate therapy for the same disease/indication. This is very sensible operationally. For example, when conducting a longitudinal analysis comparing patients diagnosed with a disease to those without it, it is often more appropriate to align the index date in the “non-diseased” group with a healthcare encounter (for whatever reason) to create a better-matched comparison.
I also found the use of Negative/Positive Control Outcomes to be highly practical. Since confounding and bias can never be eliminated entirely, these controls are useful for demonstrating the robustness of results. A negative control outcome—an outcome believed to have no causal relation to the exposure (treatment)—can reveal residual confounding or bias if a spurious association appears. For instance, if the research question is whether SGLT2 inhibitors reduce heart failure in diabetes patients, then observing a significant difference in an event presumed unrelated to the drug (e.g., fractures) would suggest residual confounding in the study design. A positive control outcome is one with a well-established causal relationship to the exposure. For example, in a warfarin study, failing to observe an increased risk of bleeding would point to problems in the study design.
Lastly, the paper is critical of overreliance on p-values. Because p-values are highly dependent on sample size, very large datasets can yield statistical significance for clinically trivial differences. In other words, even if a p-value is significant, a small effect size may offer little clinical relevance. The paper recommends presenting point estimates with their 95% confidence intervals instead of relying on p-values.

We Presented Two Posters at the ISPOR RWE Summit
The Ministry of Health, Labour and Welfare’s National Database (NDB) is an extremely comprehensive database that covers Japan’s medical claims and health checkup data. While the NDB has long been available to the private sector for projects serving the public interest, the drawback has been the time and effort required before the data becomes usable.

I Tried Using NDBβ for the First Time
The Ministry of Health, Labour and Welfare’s National Database (NDB) is an extremely comprehensive database that covers Japan’s medical claims and health checkup data. While the NDB has long been available to the private sector for projects serving the public interest, the drawback has been the time and effort required before the data becomes usable.
Compared with the NDB, NDBβ lacks information on dates, regions, and providers, but it contains the same volume of data. Applications can be submitted through a simplified monthly review process, and once approved, access is granted within a few days. The system has been in operation since February of this year. We applied in February and conducted a pilot study. An article describing the process has been published in the July 1 issue of Shakai Hoken Junpo (Social Insurance Weekly Report).

This study shows the actual conditions of testing, diagnosis, and prescription of antiviral drugs for influenza patients in Japan using the Ministry of Health, Labor and Welfare's National Database (NDB).
Since NDB is a highly comprehensive database for all citizens, we took advantage of its characteristics to conduct sub-analyses from various perspectives, such as age, insurance type, facility size, and prefecture, and examined the impact.
In this study, we used specially extracted data that allows us to use all the information of the NDB, but the number of NDBs has recently increased, such as NDB-β, which has some limitations on the items of data provided but can be used quickly with a simple review.
Recently, it has become possible to use NDB using clouds. This requires the usual review, but since the researchers directly cut out the necessary data from the entire NDB and use it, the period from the end of the review to the start of data use will be significantly shortened compared to the specially extracted data so far.

A paper using NDB with Prof. Ikegami of Keio University and Prof. Igarashi of the University of Tokyo has been published (April 11, 2025)
We are pleased to announce that a paper by Dr. Naoki Ikegami of Keio University and Dr. Ataru Igarashi of the University of Tokyo entitled "The Actual Situation of Prescription of Therapeutic Drugs for Novel Coronavirus Infections under Insurance Treatment Based on National Database (NDB) Analysis" has been published in Social Insurance Junpo No. 2960 (April 11, 2025).
This paper examines the response to COVID-19 in Japan by showing the actual situation of drug prescription under insurance treatment for COVID-19 treatment from the beginning of the COVID-19 outbreak through an analysis of the NDB.
At the beginning of the outbreak of COVID-19, there were few drugs that were found to be effective, and guidelines and other drug candidates were presented including off-label use of drugs listed in the NHC, and the Ministry of Health, Labor and Welfare supported the prescription of such drugs. The NDB's analysis showed that such non-ineligible prescriptions were actually carried out under health insurance.
In this study, we used specially extracted data that allows us to use all the information of NDB, but the number of NDBs has recently increased, such as NDB-β, which has some limitations in the items of data provided but can be used quickly with simple screening.

We presented a poster at the Japanese Association for Mathematical Sociology Conference (March 14, 2025)
On March 13, 2025, we presented a poster titled “Topics in Films and Social Interest: An Analysis Using Topic Modeling” at the 78th Conference of the Mathematical Sociology Society.
This poster was developed under the guidance of Professor Yoshimichi Sato, Dean of the Faculty of Humanities at Kyoto University of Advanced Science. It aims to explore the evolution of societal values by analyzing the synopses of films from 1950 to 2000. Using topic modeling, we identified ten “topics,” each consisting of several keywords, and examined how the prevalence of these topics changed over time.
Indeed, the trend in the prevalence of the topic labeled “Personal Life” closely mirrored the trend in “Future Outlook” as surveyed by the Institute of Statistical Mathematics. This suggests that the other topics identified in the analysis may also reflect shifts in societal values.
If this is the case, it means we have conducted a study of past values that could not be achieved through traditional surveys.
For further details, please feel free to contact us.
We aim to analyze not only so-called real-world data but also various historical data.

Healthcare Embedded Value Accounting――Management Accounting for Health Service Evaluation and Decision-Making Support（February 3, 2025）
We would like to inform you that the above paper has been published in Social Insurance Bulletin No. 2953.
Currently, the most important challenge for health insurers in Japan is the effective and efficient management of health services.
However, current financial accounting does not map the cost and return of health services to time periods, making it difficult to capture the true outcomes of health projects. One approach to better understanding the outcomes of these projects is through "Healthcare Embedded Value Accounting (HEV Accounting)."
The HEV accounting mechanism is similar to the potential value accounting employed by life insurance companies, which consists of the insurer's net worth and the present value of future profits (the difference between the standard medical expenses if the health services were not carried out and the actual medical expenses if the health services were implemented). By comparing this to insurance business expenses, insurers can more accurately understand their return on investment (ROI).
One benefit of using HEV accounting is that it enables insurers to evaluate the effectiveness of their health services in a timely manner and effectively implement the PDCA cycle. This allows insurers to make better decisions based on detailed information that cannot be obtained through financial accounting alone.
We would like you to refer to this paper for more information on HEV accounting and invite you to contact us at the address below if you have any comments or questions.

A paper on the impact of climate change on winter mortality has been published (December 3, 2024)
We are pleased to announce that one of our offices has published a paper on the subject on our website.
Title of the paper：The impact of climate change on winter mortality: A complex phenomenon with an uncertain future
https://www.milliman.com/en/insight/the-impact-of-climate-change-on-winter-mortality
While there have been many previous studies on the effects of heat waves on the mortality rate of climate change, the impact of low temperatures on mortality has not been fully understood. In this study, we evaluated the impact of low winter temperatures on health and mortality and developed a model to predict the future effects of climate change on the human body.
The impact of low winter temperatures on mortality can be direct due to frostbite and hypothermia, or indirect, such as an increase in cardiovascular disease, respiratory disease, and infectious diseases. To analyze this effect, in addition to the traditional Lee-Carter model, the Distributed Lag Non-Linear Model (DLNM) is used to show the mortality data and incorporate the mortality rate due to winter weather conditions into the dynamic model. DLNM is a model that takes into account the lag of a factor when the effects of a factor appear gradually over time. This lag is nonlinear, so we need to model the nonlinear shape.

A causal model for climate change and inflation（20th Aug 2024)
Our London office has published a paper titled “Inflation as a major climate-related risk”, so I would like to introduce the summary.
The essence of climate change is that humans have used the Earth’s resources for free. For a sustainable future, we need to stop using them for free, which will cause inflation.
However, how climate change leads to inflation is complex, and Milliman has just created a framework for a causal model. This framework is shown in Figure 1 of this paper.
Compared to the conventional frequency-severity model, the causal model has the advantages of being possible without past data, of having a good understanding of the causal mechanism, and of being able to simulate various policies.
The next step is to estimate the probability of each transition within this causal model framework. After that, validation is performed.
