Is sub-national healthcare social protection sufficient for protecting rare disease patients? the case of China.

Background: Failing to provide social support to cover healthcare costs for rare diseases would lead to great financial distress for the patients and their families. People from countries without a well-developed health safety-net are particularly vulnerable. Existing literature on rare diseases in China focuses on the unmet needs for care of the patients and the difficulties of caregivers and physicians. Very few studies examine the state of social safety-net, the unresolved issues and whether the current localized arrangements are sufficient. This study aimed to gain in-depth knowledge of the current policy system and make sense of the local varieties, which would be essential for developing strategies for future policy changes. Methods: This systematic policy review focuses on the provincial level policies on subsidizing the healthcare costs for people with rare diseases in China. The cut-off point for the policies was March 19, 2022. The researchers coded the healthcare cost reimbursement policies and identified the different provincial level models based on the usage of reimbursement components in each provinces reimbursement arrangements. Results: 257 documents were collected. Five provincial level models (Process I, II, III, IV and V) have been identified with the five components across the country: Basic Medical Insurance for Outpatient Special Diseases (OSD), Catastrophic Medical Insurance for Rare Diseases (CMIRD), Medical Assistance for Rare Diseases (MARD), Special Fund for Rare Diseases (SFRD) and Mutual Medical Fund (MMF). The local health safety-net in each region is a combination of one or more of the five processes. Regions vary greatly in their rare diseases coverage and reimbursement policies. Conclusion: In China, the provincial health authorities have developed some level of social protection for rare disease patients. However, there are still gaps regarding coverage and regional inequality; and there is room for a more integrated healthcare safety-net for people suffering from rare diseases at the national level.

Cost-effectiveness analysis of newborn screening by tandem mass spectrometry in Shenzhen, China: value and affordability of new screening technology.

BACKGROUND: Newborn screening (NBS) can prevent inborn errors of metabolism (IEMs), which may cause long-term disability and even death in newborns. However, in China, tandem mass spectrometry (MS/MS) screening has just started. This study aimed to assess the cost-effectiveness of NBS using MS/MS in Shenzhen under the nationally recommended program, as well as evaluate the value and affordability of introducing this new screening technology. METHODS: A Markov model was built to estimate the cost and quality-adjusted life-years (QALYs) of different screening programs. We compared PKU screening using traditional immunofluorescence (IF) with the other 11 IEMs not screened and all 12 IEMs screened using MS/MS, and the programs detecting different numbers of IEMs chosen from the national recommended program were also compared. A sensitivity analysis and budget impact analysis (BIA) were performed. RESULTS: The incremental cost-effectiveness ratio (ICER) of detecting all 12 IEMs in the national program is 277,823 RMB per QALY, below three times per capita GDP in Shenzhen. MS/MS screening in Shenzhen can be cost-effective only if at least three diseases (PKU, PCD and MMA) are covered and when the screening program covers five diseases (PKU, PCD, MMA, MSUD, IVA), the ICER closely approaches its critical threshold. The BIA indicated the implementation cost of the national program to be around 490 million RMB over 10 years and showed no difference in budget between programs detecting different numbers of IEMs. CONCLUSIONS: We conclude that the newborn screening using MS/MS in Shenzhen is cost-effective, and the budget affordable for the Shenzhen government. Two concepts for selecting the IEMs to be detected are also presented. One is to choose the most cost-effective screening programs detecting highest number of IEMs to achieve a minimal ICER. The other considers the curability and affordability of the disease as the basis of healthcare decisions to screen suitable IEMs, achieving an ICER under the threshold and close to the minimum value.
