The sustainability of JKN financial and the sustainability of the program is a concern, especially with the JKN deficit since 2014.In recent years, JKN expenditures have been greater than revenues, so there is a risk of financial sustainability. The JKN funding gap is predicted to increase if policymakers do not consider strategic options to improve the sustainability of JKN funding. Moreover, policies in the JKN program must support the improvement of service quality and the achievement of Universal Health Coverage. The COVID-19 pandemic has also been a challenge to ensure the sustainability of JKN financing.

Evidenced-based studies are needed to support appropriate policies for the health financing system. JKN financial modeling is expected to be an academic, scientific and rational process in the process of making policies related to the sustainability of JKN funding.

Center for Health Financing and Insurance of the Ministry of Health (PPJK) together with USAID Health Financing Activity (HFA) and Center for Health Economics and Policy Studies (CHEPS FKM UI) was conducted a half-day workshop "JKN Funding Modeling (JFM)". The purpose of this workshop is to present the methods and analysis of JKN financial modeling. In particular, this workshop serves as a forum to discuss the results of historical profile analysis and estimates of JKN revenues and expenditures based on actuarial modeling; to create supply and demand policy scenarios and their impact on JKN revenues and expenditures; and to generate simulations of the financial needs of various policies to strengthen JKN.

This workshop aims to disseminate the JKN modeling method that has been built and modified by considering the policy scenarios that will be implemented in JKN and to get feedback from stakeholders including experts and academics.

Specifically, this Workshop aims to:

1. Present the structure of the JKN funding model to generate key parameters in the estimation of JKN medical costs.
2. Identify types of policies on the supply and demand sides which are considered as not conflicting with the concepts, regulations, and philosophy of the social insurance program, and potentially capable of maintaining the sustainability of JKN program funding and service quality.
3. Present the utilization data analysis results and simulations of changes in rates and fees from several evidence-based policy options that affect the conditions of JKN funding and service quality.

The workshop held on September 23^rd , 2021 through Online meeting (zoom), started with an opening and introduction from CHEPS FKM UI and presentation of Overview JFM Protocol, Basic Model JFM and Extended Model JFM. Followed by discussion session with the invitees (stakeholders in JKN policies, academics, researchers and other participants). More than 100 participants join this session.

The discussion results from this workshop used to enriched the methods and applications of JKN Financial Modeling. JKN Financial Modeling is expected to become a joint product that can be institutionalized in the future, to produce estimates of medical costs, estimates of JKN funding profiles, identify types of policies on the supply and demand sides, and agree on policy option that can maintain the sustainability of JKN program funding.
