Sintilimab is an IgG4 anti-programmed cell death protein 1 (PD-1) antibody that has a high-affinity blocking interaction with PD-1 and its ligands. The updated ORIENT-11 study showed that sintilimab plus chemotherapy significantly prolonged progression-free and overall survival, compared with chemotherapy alone, in the first-line treatment of non-squamous non-small cell lung cancer (NSCLC). In China, it is uncertain whether sintilimab is a cost-effective alternative to standard immunotherapy.

A partitioned survival model with three health states (including progression-free survival, disease progression, and death) was constructed from the Chinese societal perspective using a three-week cycle with a lifetime horizon (16 years). Individual patient data were captured from the updated ORIENT-11 study, and high-risk and clinically severe adverse events were specifically added to the states. Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs) were the primary outcomes. Costs, health productivity losses, and utilities were derived from questionnaires and supplemented by expert opinion and literature review. All costs were expressed in 2021 USD, and costs and QALYs were discounted at an annual rate of five percent. Sensitivity analyses and scenario analyses considering the healthcare system perspective were performed to explore model uncertainty.

Patients receiving sintilimab plus chemotherapy incurred a mean total cost of USD67,727 and gained 2.5 QALYs during the lifetime period, compared with USD40,530 and 1.5 QALYs for patients receiving standard chemotherapy. The corresponding ICER was USD27,665 per QALY in China. At a willingness-to-pay threshold of three times the gross domestic product per capita in China (USD37,663), sintilimab plus chemotherapy was the optimal treatment in 84 percent of replications. Deterministic sensitivity analysis showed that the most significant driving determinant was the discount rate of costs and QALYs. An ICER of USD21,020 per QALY was obtained from the Chinese healthcare system, validating the robustness of the cost-effectiveness analysis.

Compared with standard chemotherapy, sintilimab plus chemotherapy is a cost-effective treatment regimen for non-squamous NSCLC in China. Thus, sintilimab may benefit Chinese patients and should be promoted by decision makers.

With the disease spectrum changing in China, type 2 diabetes mellitus (T2DM) has become the main chronic disease which affects people’s health severely, bring patients serious economic burden of disease. For T2DM patients, reliable quality of evidence in decision-making are significant, improving the efficiency of the adjustment of the National Reimbursement Drug List (NRDL). Based on the Consolidated Health Economic Evaluation Reporting Standards (CHEERS), we aimed to evaluate the quality of all published pharmacoeconomic evaluations on T2DM drugs in 2020 NRDL.

Because the 2020 NRDL came into effect on 1 March 2021, we searched all published pharmacoeconomic evaluations about T2DM drugs in 2020 NRDL before March 2021 in China National Knowledge Infrastructure (CNKI), Wan fang Data, China Science and Technology Journal Database (VIP), PubMed, and Web of Science. According to the criterion of inclusion and exclusion, all documents were screened and then relevant basic information of targeted documents was extracted. The quality was evaluated by calculating the final scores based on CHEERS. Two reviewers assessed each publication’s quality using the CHEERS instrument and summarized study quality.

A total of 910 papers were searched, and 24 papers were included. These involved six T2DM drugs, specifically IDegAsp, exenatide, liraglutide, lixisenatide, dapagliflozin and empagliflozin. The average score was 18.31, the standard deviation was 3.67, and the average scoring rate was 77.41 percent. Among all items, “characterizing heterogeneity” scored 0.04, least satisfied with requirements. “Setting and location”, “choice of health outcomes” and “assumptions” scored one, most satisfied with requirements. Among the average scores of all parts, “results” scored lowest at 0.55, and “methods” scored highest at 0.85. The Wilcoxon sum-rank tests showed that score rate which represented reporting quality of economic evaluation (EE) was significantly related to “journal type”, “EEs type”, “model choice” and “study perspective”.

The methodological quality of pharmacoeconomic evaluations about T2DM drugs in 2020 NRDL needs to be improved. Improving the quality of literature is the basic guarantee of scientific decision-making in national medical insurance negotiation.

According to the Healthy China 2030 Plan, children under 5 years is the main focus group to achieve universal health and sustainable development of China. To identify the major threats to children’s health, we analyzed and compared the burden of disease and risk factors among children under 5 years in China and other regions.

Indicators were gathered from the Global Burden of Disease 2019, which included the standardized rates and risk factors of mortality and DALYs of children under 5 years in China, Western Europe, North America and the world from 1990 to 2019. Paired t-test or Wilcoxon test were used to compare the rates based on gender. A joinpoint regression model was used to analyze the trend, and the Annual Percent of Change (APC) was calculated and statistically tested.

From 1990 to 2019, the all-cause mortality and DALYs of children under 5 years in China decreased from 1 153.81/100 000 to 160.39/100 000 and 104 426.40/100 000 to 16 479.01/100 000, respectively. The top 3 causes of both death and DALYs were neonatal preterm birth, congenital heart anomalies, lower respiratory infections. The top 3 risk factors of both death and DALYs were low birth weight, short gestation, child wasting. Unintentional injuries, behavioral and environmental risks posed greater threats to children compared with other regions. The rates of mortality and DALYs of the top 15 diseases and injuries in boys and girls showed a downward trend (p<0.05), and most of them were higher in boys than girls (p<0.05).

The burden of diseases among children under 5 years in China has decreased significantly from 1990 to 2019. Compared to other regions, it remains to strengthen the prevention and control of preterm birth, birth defects and unintentional injuries, and to adopt targeted gender-specific interventions. Promoting the parenting behavior and multiple social security may also affects children’s health status.
