Associations of hypertension, diabetes and heart disease risk with body mass index in older Chinese adults: a population-based cohort study.

OBJECTIVE: Obesity is a well-established risk factor for disease. Controversy exists regarding the relative risk of morbidity and mortality in individuals who are overweight or underweight compared with individuals with a normal body mass index (BMI). In this study, we investigated the associations between BMI and three non-communicable diseases (hypertension, diabetes and heart disease) in older adults. DESIGN: Cohort study. SETTING: This study used data from the China Health and Retirement Longitudinal Study. The baseline survey was carried out in 2011, and follow-up surveys were conducted in 2013, 2015 and 2018. PARTICIPANTS: Participants who reported having no doctor-diagnosed chronic disease at baseline were included in this study. MAIN OUTCOME MEASURES: We analysed the association between baseline BMI and disease incidence using Cox proportional hazards models. Disease information included self-reported diagnosed conditions. BMI was categorised according to the standard Chinese criteria: underweight (<18.5 kg/m2), normal body weight (18.5-23.9 kg/m2), overweight (24.0-27.9 kg/m2) and obese (≥28.0 kg/m2). RESULTS: A total of 5605 participants were included at baseline. Based on the Kaplan-Meier estimation, the participants who were obese had the highest incidence of all three diseases. Compared with normal weight participants, overweight participants had a greater disease incidence (log-rank tests are p<0.01). Cox regression models showed that with increasing BMI, the HRs of diseases increased accordingly (eg, for hypertension, compared with the BMI group <18.5 kg/m2, the HRs for the BMI groups 18.5-23.9, 24.0-27.9 and ≥28.0 were 1.43 (95% CI 1.00 to 2.05), 2.19 (95% CI 1.51 to 3.18) and 2.89 (95% CI 1.91 to 4.36), respectively). CONCLUSION: A higher BMI was associated with an increased risk of hypertension, diabetes and heart disease in the population aged 45 years and older. Even within normal BMI ranges, a higher BMI was associated with an increased risk of disease. Actions are urgently needed at the population level to address the growing public health challenge of excess weight in the context of an ageing population.

Key Issues of Economic Evaluations for Health Technology Assessment in China: A Nationwide Expert Survey.

OBJECTIVES: Health technology assessment (HTA) is increasingly crucial in medicine price negotiations in China, yet prior appraisals revealed national discrepancies on key economic evaluation issues: willingness-to-pay (WTP) threshold, pricing models for multi-indication medicines, and comparator selection principles. This study aims to collect expert opinions on these issues for future HTA evaluations. METHODS: A nationwide anonymous web-based survey encompassing experts across academia, HTA, consultancy/contract research organization (CRO)/industry, service provider and payer. In 2023, a generic invitation containing a web link to the questionnaire was disseminated via WeChat using convenience and snowball sampling. Agreement rates for questionnaire views were analyzed using descriptive statistics. The relationship between participants' responses and demographics was examined using appropriate logistic models. RESULTS: 303 responses were received from experts in 34 cities. Key expert views include: a suggested base WTP threshold ranging from 0.5 to 1.5 times GDP (52.1% agreement); elevated thresholds for childhood diseases, rare diseases, end-of-life diseases, and first-in-class medicines (FICs) (>78.0% agreement); a single pricing model for multi-indication medicines (60.4% agreement); consideration of multiple medicines as comparators (79.9% agreement); and avoiding the use of centrally procured medicines as comparators for medicines with a time-to-market under three years (71.0% agreement). Participants who are service provider had lower odds of selecting higher thresholds (OR: 0.26; P<0.01) compared with responders from consultancy/CRO/industry. CONCLUSIONS: Expert views indicate the need for substantial changes in China's current HTA methods, highlighting the need for increased investment in HTA processes and expertise cultivation.

Alcohol Consumption Patterns for Excessive Drinkers in a Multi-Ethnic Society Short Running Title: Drinking Patterns and Health Education.

Objective: Culture and eating habits, which vary greatly across different ethnic groups, have a substantial impact on drinking behavior. This study aimed to examine whether the drinking patterns and reasons differ by ethnic groups, and provide useful insights for multi-ethnic areas that seek to cut down alcohol intake. Methods: We recruited excessive drinkers and collected the drinking patterns and motivations by questionnaire in a multi-ethnic society. Multiple linear regressions were used to evaluate the variations in drinking characteristics among different ethnic groups. Results: We recruited 1287 participants through convenience sampling (a non-probability sampling technique used in research where the researcher selects participants or units for a study based on their accessibility and proximity), among whom 439 excessive drinkers were eligible. The mean age was 38 years for the 439 participants, 92.9% were men, 36.0% were Han, and 64.0% were minorities mainly composed of the Yi. The majority of the participants were married (75.9%) and did physical work (58.1%). Ethnic minorities consumed more alcohol on a single occasion than Han people did (47.3 vs 41.8g/session) while drinking less frequently. For the minority and Han participants, 67% and 42% were not used to drinking with food, respectively. Peer pressure and fostering a good atmosphere were the most common drinking reasons for the minority and Han, respectively. Conclusion: We found substantial differences in drinking patterns and reasons between ethnic minorities and Han ethnicity, attributable to their culture and customs. Findings highlight the importance of drinking habits and motivations in exploring alcohol control education strategies in the context of ethnic integration and population immigration.

Temporal trends and disparities of population attributable fractions of modifiable risk factors for dementia in China: a time-series study of the China health and retirement longitudinal study (2011-2018).

Background: In China, dementia poses a significant public health challenge, exacerbated by an ageing population and lifestyle changes. This study assesses the temporal trends and disparities in the population-attributable fractions (PAFs) of modifiable risk factors (MRFs) for new-onset dementia from 2011 to 2018. Methods: We used data from the China Health and Retirement Longitudinal Study (CHARLS), covering 75,214 person-waves. We calculated PAFs for 12 MRFs identified by the Lancet Commission (including six early-to mid-life factors and six late-life factors). We also determined the individual weighted PAFs (IW-PAFs) for each risk factor. Subgroup analyses were conducted by sex, socio-economic status (SES), and geographic location. Findings: The overall PAF for dementia MRFs had a slight increase from 45.36% in 2011 to 52.46% in 2018, yet this change wasn't statistically significant. During 2011-2018, the most contributing modifiable risk was low education (average IW-PAF 11.3%), followed by depression, hypertension, smoking, and physical inactivity. Over the eight-year period, IW-PAFs for risk factors like low education, hypertension, hearing loss, smoking, and air pollution showed decreasing trends, while others increased, but none of these changes were statistically significant. Sex-specific analysis revealed higher IW-PAFs for traumatic brain injury (TBI), social isolation, and depression in women, and for alcohol and smoking in men. The decline in IW-PAF for men's hearing loss were significant. Lower-income individuals had higher overall MRF PAFs, largely due to later-life factors like depression. Early-life factors, such as TBI and low education, also contributed to SES disparities. Rural areas reported higher overall MRF PAFs, driven by factors like depression, low education, and hearing loss. The study also found that the gap in MRF PAFs across different SES groups or regions either remained constant or increased over the study period. Interpretation: The study reveals a slight but non-significant increase in dementia's MRF PAF in China, underscoring the persistent relevance of these risk factors. The findings highlight the need for targeted public health strategies, considering the demographic and regional differences, to effectively tackle and reduce dementia risk in China's diverse population. Funding: This work was supported by the PKU Young Scholarship in Global Health and Development.

Prescription medication use among patients with type 2 diabetes in the United States: 1999-2020.

AIMS: We aimed to examine trends in overall prescription medication use among patients with type 2 diabetes in the United States to provide insights for patient care. MATERIALS AND METHODS: We used nationally representative data from the National Health and Nutrition Examination Survey from 1999 to 2020 and included adult patients with type 2 diabetes. We examined the use of prescription drugs, overall and by drug class, polypharmacy (use of ≥5 medications), and number of medications attributed to specific classes. RESULTS: In the period 2015-2020, the mean patient age was 59.6 (51.0-70.0) years, with 46.8% (43.6-49.9) being female and 57.8% (52.8-62.8) being non-Hispanic White. Among 9489 adults with type 2 diabetes, the prevalence of polypharmacy was high and increased from 35.1% (31.6-38.6) in 1999-2002 to 47.2% (43.7-50.7) in 2003-2006, and further to 51.1% (48.3-53.9) in 2015-2020 (p for trend <0.001). Increasing trends of polypharmacy were found across all population subgroups and across the majority of therapeutic classes. Use of non-cardiometabolic medications was common. Among them, the most common were antidepressants (19.8%), proton pump inhibitors (19.0%) and analgesics (16.2%). Among patients with polypharmacy, approximately 40% of medication use was attributed to non-cardiometabolic medications. CONCLUSIONS: Prescription medication burden and complexity increased substantially among patients with type 2 diabetes, with more than 50% of patients with polypharmacy. Attention should be paid to this escalating medication use and regimen complexity, which requires multidisciplinary and coordinated care.

Health insurance and subjective well-being: evidence from integrating medical insurance across urban and rural areas in China.

Health insurance coverage and the risk protection it provides may improve enrollees' subjective well-being (SWB), as demonstrated, e.g. by Oregon Medicaid's randomized expansion significantly improving enrollees' mental health and happiness. Yet little evidence from low- and middle-income countries documents the link between insurance coverage and SWB. We analyse individual-level data on a large natural experiment in China: the integration of the rural and urban resident health insurance programmes. This reform, expanded nationally since 2016, is recognized as a vital step towards attaining the goal of providing affordable and equitable basic healthcare in China, because integration raises the level of healthcare coverage for rural residents to that enjoyed by their urban counterparts. This study is the first to investigate the impact of urban-rural health insurance integration on the SWB of the Chinese population. Analysing 2011-18 data from the China Health and Retirement Longitudinal Study in a difference-in-difference framework with variation in the treatment timing, we find that the integration policy significantly improved the life satisfaction of rural residents, especially among low-income and elderly individuals. The positive impact of the integration on SWB appears to stem from the improvement of rural residents' mental health (decrease in depressive symptoms) and associated increases in some health behaviours, as well as a mild increase in outpatient care utilization and financial risk protection. There was no discernible impact of the integration on SWB among urban residents, suggesting that the reform reduced inequality in healthcare access and health outcomes for poorer rural residents without negative spillovers on their urban counterparts.

Trends in Number and Appropriateness of Prescription Medication Utilization Among Community-Dwelling Older Adults in the United States: 2011-2020.

BACKGROUND: Contemporary data on the quantity and quality of medication use among older adults are lacking. This study examined recent trends in the number and appropriateness of prescription medication use among older adults in the United States. METHODS: Data from the National Health and Nutrition Examination Survey (NHANES) between 2011 and March 2020 were used, and 6 336 adult participants aged 65 and older were included. We examined the number of prescription medication, prevalence of polypharmacy (≥5 prescription drugs), use of potentially inappropriate medication (PIM), and use of recommended medications (angiotensin-converting enzyme inhibitor [ACEI]/angiotensin receptor blockers [ARBs] plus beta-blockers among patients with heart failure and ACEI/ARBs among patients with albuminuria). RESULTS: There has been a slight increase in the prevalence of polypharmacy (39.3% in 2011-2012 to 43.8% in 2017-2020, p for trend = .32). Antihypertensive, antihyperlipidemic, antidiabetic medications, and antidepressants are the most commonly used medications. There was no substantial change in the use of PIM (17.0% to 14.7%). Less than 50% of older adults with heart failure received ACEI/ARBs plus beta-blockers (44.3% in 2017-2020) and approximately 50% of patients with albuminuria received ACEI/ARBs (54.0% in 2017-2020), with no improvement over the study period. Polypharmacy, older age, female, and lower socioeconomic status were generally associated with greater use of PIM but lower use of recommended medications. CONCLUSIONS: The medication burden remained high among older adults in the United States and the appropriate utilization of medications did not improve in the recent decade. Our results underscore the need for greater attentions and interventions to the quality of medication use among older adults.

Hospitalization Costs for Patients with Acute Appendicitis: An Update Using Real-World Data from a Large Province in China.

Purpose: The aim of this study is to investigate the factors influencing hospitalization costs for patients diagnosed with acute appendicitis in China. Methods: We conducted a cross-sectional study using data from Provincial Health Statistics Support System Database from S Province in China. This dataset contained all hospital's electronic medical records from January 1, 2015 to December 31, 2018 including both public and private hospitals. The target population was identified based on the principal diagnosis of appendicitis (ICD-10: K35). To examine the impact of various factors on hospitalization costs, we conducted a multivariate linear regression analysis. Furthermore, we employed the Shapley value decomposition method to gain a more comprehensive understanding of the factors that influenced hospitalization costs and their respective levels of importance. Results: Our study comprised 317,200 cases. During the period from 2015 to 2018, the average hospitalization expenses for patients with acute appendicitis were estimated at approximately 7014 RMB (1061 USD), which accounts for a considerable 12% of China's per capita GDP. The results of this study demonstrate a significant correlation between various factors, such as the patient's age, gender, marital status, occupation, payment method, number of complications, treatment method, hospital tier, and ownership, and the total hospitalization costs and subcomponents of hospitalization costs. Notably, the treatment method employed had the most substantial impact on hospitalization costs. Conclusion: To the best of knowledge, this is one of the first studies to investigate the hospitalization costs of acute appendicitis incorporating both patient-level and hospital-level covariates, using a large sample size. To reduce the costs associated with acute appendicitis in China, it is recommended to consider suitable treatment options and explore the option of receiving medical care at lower-tier and privately-owned healthcare facilities.

Efficacy of personalised text message intervention in reducing smoking frequency and amount for non-abstinent smokers: A double-blind, randomised controlled trial.

Background: Emerging evidence supports the efficacy of mobile phone interventions for smoking cessation. However, behaviour changes of smokers who fail to reach abstinence and the related psychological mechanism are still understudied. We aimed to evaluate the efficacy of a behaviour change theory-based smoking cessation intervention delivered through personalised text messages from the perspective of smokers who fail to reach abstinence. Methods: We conducted a two-arm, double-blind, randomised controlled trial, with the intervention group receiving personalised text messages developed specifically for this study, and the control group receiving non-personalised ones related to smoking cessation. These messages were sent over a period of three months. We looked at three outcomes: changes in smoking frequency, in smoking amount, and in protection motivation theory (PMT) construct scores. Results: We obtained smoking cessation results for 722 participants who went through the randomisation process (intervention: 360, control: 362; block randomisation design). Overall, 32.3% of baseline daily smokers in the intervention group and 20.0% in the control group changed to weekly smokers during the follow-up period (P < 0.001), while 43.4% of consistent daily smokers in the intervention group and 32.8% in the control group continuously reduced their smoking amount (P < 0.001). We observed associations between the intrinsic rewards of smoking and changes from daily to weekly smoking, the perceived severity of smoking and reductions in smoking amount, as well as the self-efficacy of quitting and changes from daily to weekly smoking/reductions in smoking amount. Conclusions: We found that a personalised text message-based intervention was more likely to decrease the frequency and amount of smoking in smokers who failed to reach abstinence compared to a non-personalised one. We also explored the possible psychological mechanism of such positive effects. Here we provide evidence for countries to consider the promotion of smoking cessations using behaviour theory-driven personalised text messages, which may be more cost-effective than traditional approaches.

Efficacy and safety of Lianhua Qingwen capsules combined with standard of care in the treatment of adult patients with mild to moderate COVID-19 (FLOSAN): protocol for a randomized, double-blind, international multicenter clinical trial.

Background: Effective anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) drugs are not only the next defense after vaccines but also the key part of establishing a multi-tiered coronavirus disease 2019 (COVID-19) prevention and control system. Previous studies had indicated that Lianhua Qingwen (LHQW) capsules could be an efficacious Chinese patent drug for treating mild to moderate COVID-19. However, pharmacoeconomic evaluations are lacking, and few trials have been conducted in other countries or regions to evaluate the efficacy and safety of LHQW treatment. So, this study aims to explore the clinical efficacy, safety, and economy of LHQW for treating adult patients with mild to moderate COVID-19. Methods: This is a randomized, double-blind, placebo-controlled, international multicenter clinical trial protocol. A total of 860 eligible subjects are randomized at a 1:1 ratio into the LHQW or placebo group to receive two-week treatment and follow-up visits on days 0, 3, 7, 10, and 14. Clinical symptoms, patient compliance, adverse effects, cost scale, and other indicators are recorded. The primary outcomes will be the measured median time to sustained improvement or resolution of the nine major symptoms during the 14-day observation period. Secondary outcomes regarding clinical efficacy will be evaluated in detail on the basis of clinical symptoms (especially body temperature, gastrointestinal symptoms, smell loss, and taste loss), viral nucleic acid, imaging (CT/chest X-ray), the incidence of severe/critical illness, mortality, and inflammatory factors. Moreover, we will assess health care cost, health utility, and incremental cost-effectiveness ratio (ICER) for economic evaluation. Discussion: This is the first international multicenter randomized controlled trial (RCT) of Chinese patent medicine for the treatment of early COVID-19 in accordance with WHO guidelines on COVID-19 management. This study will help clarify the potential efficacy and cost-effectiveness of LHQW in the treatment of mild to moderate COVID-19, facilitating decision-making by healthcare workers. Registration: This study is registered at the Chinese Clinical Trial Registry, with registration number: ChiCTR2200056727 (date of first registration: 11/02/2022).

A validated survey to measure Chinese hospital management practices.

Surveys are widely used to assess hospital management with the aim of understanding differences in management practices. However, survey measures with prior notice can make hospitals change their routine practices and are unable to reflect the actual hospital management level. The World Management Survey (WMS) methodology has been developed to ameliorate these issues. It uses a double-blinded method and open-ended question design. The Chinese Hospital Management Survey (CHMS) project is the first to adapt the WMS methodology in China, which it uses to measure hospital management level in 510 hospitals. This paper provides an instrument to better measure actual management practices, which makes it possible to compare the management level of hospitals in China and other countries.

Development and Validation of the Disability Index Among Older Adults.

BACKGROUND: With the rapid population aging, the challenge to provide care for disabled older adults is becoming bigger. This study aims to develop the Disability Index (DI) to assess disability to indicate care needs, and we evaluated the reliability and validity of the DI among older adults aged 65-105. METHODS: A total of 12 559 older adults (54.0% women; mean age = 84.3; SD = 11.2) from 22 provinces in China were investigated in 2017-2018. We developed the 21-item DI covering 4 subdomains, including Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), physical performance, and cognitive function. Cronbach's alpha was used to determine internal consistency. The convergent and divergent validity were assessed by Spearman rank order correlation coefficients and Pearson correlation coefficients. The known-group validity was assessed by Mann-Whitney U tests. The concurrent validity was assessed by the area under the receiver operating characteristic curve (AUC). RESULTS: In the total sample, the internal consistency of the full DI and its subdomains were satisfactory with Cronbach's alpha ≥0.70; the convergent and divergent validity of the 4 subdomains were supported by all the alternative measures; the known-group validity of the full DI and its subdomains were supported by clear discriminative ability; and the concurrent validity of the full DI was supported with all the AUCs ≥0.70. The reliability and validity of the full DI and its subdomains were additionally supported by age subgroups and sex subgroups. CONCLUSIONS: The DI is a reliable and valid instrument to assess disability status among older adults.

Geographic Variation in Inpatient Care Utilization, Outcomes and Costs for Dementia Patients Aged 65 Years or Older - China, 2017-2019.

What is already known about this topic?: Dementia leads public health issues worldwide. China has the largest population of adults living with dementia in the world, imposing increasing burdens on the public health and healthcare systems. Despite improved access to health services, inadequate and uneven dementia management remains common. What is added by this report?: The report documents the provincial-level geographic patterns in healthcare utilization, outcomes, and costs for patients hospitalized for dementia in China. Regional patterns demonstrate gaps in equity and efficiency of dementia care and management for dementia patients. What are the implications for public health practice?: Public health policy and practices should consider geographic disparities in disease burden and healthcare provision to promote equitable allocation of resources for dementia care throughout China.

Cost-effectiveness of folic acid therapy for primary prevention of stroke in patients with hypertension.

BACKGROUND: For hypertensive patients without a history of stroke or myocardial infarction (MI), the China Stroke Primary Prevention Trial (CSPPT) demonstrated that treatment with enalapril-folic acid reduced the risk of primary stroke compared with enalapril alone. Whether folic acid therapy is an affordable and beneficial treatment strategy for the primary prevention of stroke in hypertensive patients from the Chinese healthcare sector perspective has not been thoroughly explored. METHODS: We performed a cost-effectiveness analysis alongside the CSPPT, which randomized 20,702 hypertensive patients. A patient-level microsimulation model based on the 4.5-year period of in-trial data was used to estimate costs, life years, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) for enalapril-folic acid vs. enalapril over a lifetime horizon from the payer perspective. RESULTS: During the in-trial follow-up period, patients receiving enalapril-folic acid gained an average of 0.016 QALYs related primarily to reductions in stroke, and the incremental cost was $706.03 (4553.92 RMB). Over a lifetime horizon, enalapril-folic acid treatment was projected to increase quality-adjusted life years by 0.06 QALYs or 0.03 life-year relative to enalapril alone at an incremental cost of $1633.84 (10,538.27 RMB), resulting in an ICER for enalapril-folic acid compared with enalapril alone of $26,066.13 (168,126.54 RMB) per QALY gained and $61,770.73 (398,421.21 RMB) per life-year gained, respectively. A probabilistic sensitivity analysis demonstrated that enalapril-folic acid compared with enalapril would be economically attractive in 74.5% of simulations at a threshold of $37,663 (242,9281 RMB) per QALY (3x current Chinese per capita GDP). Several high-risk subgroups had highly favorable ICERs < $12,554 (80,976 RMB) per QALY (1x GDP). CONCLUSIONS: For both in-trial and over a lifetime, it appears that enalapril-folic acid is a clinically and economically attractive medication compared with enalapril alone. Adding folic acid to enalapril may be a cost-effective strategy for the prevention of primary stroke in hypertensive patients from the Chinese health system perspective.

A taxonomy of Chinese hospitals and application to medical dispute resolutions.

Medical disputes can be viewed as a negative indicator of health care quality and patient satisfaction. However, dispute prevention from the perspective of systematic supervision is unexplored. This study examines hospital clustering based on diagnosis-related group (DRG) indicators and explores the association between hospital clusters and medical disputes. Health administrative data from Sichuan Province in 2017 were used. A twostep cluster analysis was performed to cluster hospitals based on DRG indicators. A multiple regression analysis was conducted to evaluate the relationship between clusters and the incidence/number of medical disputes. The 1660 hospitals were grouped into three DRG clusters: basic (62.5%, n = 1038), diverse (31.0%, n = 515), and lengthy (6.4%, n = 107). After adjusting for covariates, the diverse hospitals were associated with an increased probability of having medical disputes (OR 5.24, 95% CI 2.97-9.26), while the diverse and lengthy hospitals were associated with a greater number of medical disputes (IRR 10.67, 95% CI 6.58-17.32; IRR 4.06, 95% CI 1.22-13.54). Our findings highlighted that the cluster-level performance of hospitals can be monitored. Future studies could examine this relationship using a longitudinal design and explore ways to reduce medical disputes in hospitals.

Incorporating productivity loss in health economic evaluations: a review of guidelines and practices worldwide for research agenda in China.

INTRODUCTION: Productivity loss may contribute to a large proportion of costs of health conditions in an economic evaluation from a societal perspective, but there is currently a lack of methodological consensus on how productivity loss should be measured and valued. Despite the research progress surrounding this issue in other countries, it has been rarely discussed in China. METHODS: We reviewed the official guidelines on economic evaluations in different countries and regions and screened the literature to summarise the extent to which productivity loss was incorporated in economic evaluations and the underlying methodological challenges. RESULTS: A total of 48 guidelines from 46 countries/regions were included. Although 32 (67%) guidelines recommend excluding productivity loss in the base case analysis, 23 (48%) guidelines recommend including productivity loss in the base case or additional analyses. Through a review of systematic reviews and the economic evaluation studies included in these reviews, we found that the average probability of incorporating productivity loss in an economic evaluation was 10.2%. Among the economic evaluations (n=478) that explicitly considered productivity loss, most (n=455) considered losses from paid work, while only a few studies (n=23) considered unpaid work losses. Recognising the existing methodological challenges and the specific context of China, we proposed a practical research agenda and a disease list for progress on this topic, including the development of the disease list comprehensively consisting of health conditions where the productivity loss should be incorporated into economic evaluations. CONCLUSION: An increasing number of guidelines recommend the inclusion of productivity loss in the base case or additional analyses of economic evaluation. We optimistically expect that more Chinese researchers notice the importance of incorporating productivity loss in economic evaluations and anticipate guidelines that may be suitable for Chinese practitioners and decision-makers that facilitate the advancement of research on productivity loss measurement and valuation.

Effect of a brief intervention with small financial incentives on alcohol consumption in China: study protocol for a randomised controlled trial.

INTRODUCTION: Alcohol consumption is the seventh leading risk factor for disability-adjusted life years in the world, according to the Global Burden of Disease Study 2017. As the largest developing country, China has a substantial population of alcohol consumers who suffer from related health risks. Despite having made significant advancements in eradicating absolute poverty, many people still live in relative poverty, which suggests that the adverse health effects caused by alcohol consumption among vulnerable populations in China warrant more attention. This paper aims to provide an overview of alcohol consumption among ethnic populations in China and test the feasibility and efficacy of a brief advice intervention with a small financial incentive in reducing harmful drinking behaviours. METHODS: This study is a three-arm, single-blinded, pragmatic, individually randomised controlled trial with follow-ups at 1,2 and 3 months after randomisation. A total of 440 daily drinkers living in Xichang will be recruited and divided into three groups: brief intervention group, financial incentive group and control group. All participants will receive a urine ethyl glucuronide (EtG) test, which detects alcohol consumption in the past 80 hours. Additionally, participants in the brief intervention group will receive three free counselling sessions alongside multimedia messages on the topic of alcohol consumption after each session. The participants in the financial incentive group will receive the same interventions as well as cash incentives according to the results of the EtG test. The primary outcomes are the self-reported drinking quantity, binge drinking frequency, drinking intensity and the proportion of participants who pass the EtG test. ETHICS AND DISSEMINATION: This protocol was approved by the Peking University Health Science Center Institutional Review Board (IRB00001052-20049). Findings will be published in peer-reviewed journals and presented at local, national and international conferences to publicise and explain the research to key audiences. TRIAL REGISTRATION NUMBER: NCT04999371.

Policy Updates on Access to and Affordability of Innovative Medicines in China.

INTRODUCTION: In China, efforts to qualify innovative medical products for reimbursement used to be subject to substantial delays after regulatory approval due to fiscal and bureaucratic barriers. In this review, we surveyed the Chinese government's most recent initiatives to improve access to innovative medicines from both the regulatory and the reimbursement aspects, which not only accelerated the launching of drugs in the Chinese market but also expanded the reimbursement coverage of such products. We also provided a discussion of the current challenges. AREAS COVERED: We provided a comprehensive review of the updates in China's national reimbursement listing policies of medicines. EXPERT OPINION: As the most recognized regulatory shortcuts, priority and conditional approvals have expedited the authorization of many innovative medicines. In addition, the national negotiation process was institutionalized to enable timely access to innovative medicines through the National Reimbursement Drug List, leading examples of which were new anticancer drugs. Other impactful reimbursement policies in recent years included dynamic updates of the National Reimbursement Drug List, manufacturer-initiated reimbursement coverage applications, and parallel fund robustness tests and pharmacoeconomic analyses for price estimation. Recent administrative efforts have substantially improved the access to and affordability of innovative medicines in China. Nevertheless, standardized and transparent evidence appraisal processes need to be established for informed decision making in the future.

Rural population's preferences matter: a value set for the EQ-5D-3L health states for China's rural population.

PURPOSE: To develop an EQ-5D-3L social value set based on Chinese rural population's preferences using the time trade-off (TTO) method, and to compare the differences in preferences on health states between China urban and rural population. METHODS: Between Sep 2013 and Nov 2013, a total of 1201 participants were recruited from rural areas of five Chinese cities (Beijing, Chengdu, Guiyang, Nanjing, and Shenyang) using a quota sampling method. Each respondent valued 13 health states using the TTO, and a total of 97 EQ-5D-3L health states were directly valued for estimating the value set. Various models with different specifications were explored at both aggregate and individual levels. The final model was determined by a set of predefined selection criteria. FINDINGS: An ordinary least square model at the aggregate level included 10 dummy variables for specifying the level 2 and 3 for each dimension and an N3 term presenting any dimension on level 3 was selected as the final model. The final model provides a value set ranges from - 0.218 to 0.859. The predicted utility values were highly correlated with but consistently lower than that of the published Chinese EQ-5D-3L value set (for urban population). CONCLUSION: The availability of the China rural value set provides a set of social preferences weights for researchers and policy decision-makers for use in China rural area.
