Prevalence of aggressive care among patients with cancer near the end of life: a systematic review and meta-analysis.

Background: Aggressive care near patients' end-of-life (EOL) entails limited therapeutic values, high costs, and compromised quality of life (QoL). In this study, we aimed to estimate the global prevalence of aggressive care in patients with cancer and explore potential subgroup differences. Methods: We searched PubMed, Embase, and the Cochrane Library from database inception to Feb 16, 2024. Eligible studies reported the prevalence of aggressive EOL care using at least one quantifiable measure. Random-effects models were used to derive the pooled prevalence and subgroup analyses were performed to investigate differences in the prevalence of aggressive care across regions, the country's level of economic development, tumor types, ages, and sample sizes. This review is registered with PROSPERO, number CRD42023467839. Findings: A total of 129 studies were included in this systematic review, of which 118 (91.5%) were from high-income countries. Studies were mostly conducted in the Americas (60, 46.5%), Europe (34, 26.4%), and Western Pacific (31, 24.0%). Measures of aggressive care were inconsistent across studies, with the most commonly used measure being the use of chemotherapy in the last 14 days of life (DOLs) (n = 87, 67.4%) and intensive care unit (ICU) stay in the last 30 DOLs (n = 87, 67.4%). The prevalence of the five claims-based measures of aggressive care, i.e., chemotherapy in the last 14 DOLs, ICU stay in the last 30 DOLs, repeated hospital admission in the last 30 DOLs, repeated emergency room (ER) visit in the last 30 DOLs, and hospice care <3 days before death were 11.6% (95% CI, 9.8%-13.4%), 14.4% (95% CI, 11.8%-17.0%), 17.9% (95% CI, 14.4%-21.4%), 14.8% (95% CI, 12.0%-17.6%), and 14.4% (95% CI, 11.2%-17.6%), respectively. Regional differences were statistically significant in the prevalence of ICU stay and repeated hospital admission in the last 30 DOLs (p < 0.01; p = 0.03). Patients with hematologic malignancies were more likely to receive aggressive care than those with solid tumors, as seen in their higher rates of chemotherapy in the last 14 DOLs (21.7% versus 11.6%; p = 0.03), ICU stay in the last 30 DOLs (25.5% versus 10.8%; p < 0.01), and hospice care <3 days before death (26.7% versus 14.2%; p < 0.01). In addition, the prevalence of chemotherapy in the last 14 DOLs (26.2%; p < 0.01) and repeated hospital admission in the last 30 DOLs (31.4%; p < 0.01) were highest among pediatric patients with cancer. Interpretation: This meta-analysis found that aggressive EOL care was common in patients with cancer, regardless of the definition used, and varied by regions and populations. It is necessary to be aware of the global burden of aggressive care for patients with cancer near their EOL and take prompt action to address it.

Sponsorship bias in published pharmacoeconomic evaluations of national reimbursement negotiation drugs in China: a systematic review.

BACKGROUND: China's National Reimbursement Drug List (NRDL) has become the primary route for drug reimbursement in China. More recently, the authority has made pharmacoeconomic evaluation an integral part of the application for NRDL inclusion. The underlying financial conflict of interests (FCOI) of pharmacoeconomic evaluations, however, has the potential to influence evidence generated and thus subsequent decision-making yet remains poorly understood. METHODS: We searched for studies published between January 2012 and January 2022 on the 174 drugs added to the 2017-2020 NRDLs after successful negotiation. We categorised the study's FCOI status into no funding, industry funding, non-profit funding and multiple fundings based on authors' disclosure and assessed the reporting quality of included studies using the Consolidated Health Economic Evaluation Reporting Standards 2022 checklist. We compiled descriptive statistics of funding types and study outcomes using t-tests and χ2 tests and conducted multivariate regression analysis. RESULTS: We identified 378 records and our final sample included 92 pharmacoeconomic evaluations, among which 69.6% were conducted with at least one funding source. More than half (57.6%) of the evaluations reached favourable conclusions towards the intervention drug and 12.6% reached a dominant result of the intervention drug over the comparison from model simulation. The reporting quality of included studies ranged from 19 to 25 (on a scale of 28), with an average of 22.3. The statistical tests indicated that industry-funded studies were significantly more likely to conclude that the intervention therapy was economical (p<0.01) and had a significantly higher proportion of resulting target drug economically dominated the comparison drug (p<0.05). CONCLUSION: The study revealed that FCOI bias is common in published pharmacoeconomic evaluations conducted in Chinese settings and could significantly influence the study's economical results and conclusions through various mechanisms. Multifaceted efforts are needed to improve transparency, comparability and reporting standardisation.

The impact of government reimbursement negotiation on targeted anticancer medicines use and cost in China: A cohort study based on national health insurance data.

Background: High prices of targeted anticancer medicines (TAMs) result in financial toxicity for patients and the health insurance system. How national price negotiation and reimbursement policy affect the accessibility of TAMs for cancer patients remains unknown. Methods: In this population-based cohort study, we used national health insurance claims data in 2017 and identified adult patients with cancer diagnoses for which price-negotiated TAMs were indicated. We estimated the half-month prevalence of price-negotiated TAMs use before and after the policy implementation in September 2017. We calculated direct medical costs, out-of-pocket (OOP) costs, and the proportion of OOP cost for each cancer patient to measure their financial burden attributable to TAMs use. We performed segmented linear and multivariable logistic regression to analyse the policy impact. Results: We included 39 391 of a total 118 655 cancer beneficiaries. After September 2017, the prevalence of price-negotiated TAMs use increased from 1.4%-2.1% to 2.9%-3.1% (P = 0.005); TAMs users' daily medical costs increased from US$261.3 to US$292.5 (P < 0.001), while median daily OOP costs (US$68.2 vs US$65.7; P = 0.134) and OOP costs as a proportion of daily medical costs persisted (28.5% vs 28.5%; P = 0.995). Compared with resident beneficiaries, the relative probability of urban employee beneficiaries on TAMs uses decreased after the policy (adjusted odds ratio (aOR) = 2.4 vs aOR = 2.2). Conclusions: The government price negotiation and reimbursement policy improved patient access to TAMs and narrowed disparities among insurance schemes. China's approach to promoting the affordability of expensive medicines provides valuable experience for health policy decision-makers.

The Impact of Prescribing Monitoring Policy on Drug Use and Expenditures in China: A Multi-center Interrupted Time Series Study.

BACKGROUND: A prescribing monitoring policy (PMP) was implemented in November 2015 in Anhui province, China, the first province to pilot this policy to manage the use and costs of select drugs based on their large prescription volumes and/ or costs in hospitals. This study evaluated the impact of PMP on the use and expenditures of different drugs in three tertiary hospitals in Anhui. METHODS: We obtained monthly drug use and expenditures data from three tertiary hospitals in Anhui (November 2014 through September 2017). An interrupted time series (ITS) design was used to estimate changes in defined daily doses (DDDs per month) and drug expenditures (dollars per month) of policy-targeted and non-targeted drugs after PMP implementation. Drugs were grouped based on whether they were recommended (recommended drugs) by any clinical guidelines or not (non-recommended drugs), or if they were potentially over-used (proton pump inhibitors, PPIs). RESULTS: After PMP, DDDs and costs of the targeted PPIs (omeprazole) declined while use of non-targeted PPIs increased correspondingly with overall sustained declines in total PPIs. The policy impact on recommended drugs varied based on whether the targeted drugs have appropriate alternatives. The DDDs and costs of recommended drugs that have readily accessible appropriate alternatives (atorvastatin) declined, which offset increases in its alternative non-target drugs (rosuvastatin), while there was no significant change in those recommended drugs that did not have appropriate alternative drugs (clopidogrel and ticagrelor). Finally, the DDDs and costs of non-recommended drugs decreased significantly. CONCLUSION: PMP policy impact was not the same across different drug groups. PMP did help contain the use and costs of potentially over-used drugs and non-recommended drugs. PMP did not seem to reduce the use of first-line therapeutic drugs recommended by clinical treatment guidelines, especially those lacking alternatives; such drugs are unlikely appropriate candidates for PMP.

Effect of the full coverage policy of essential medicines on medication adherence: A quasi-experimental study in Taizhou, China.

Objective: Different forms of full coverage policy of essential medicines (FCPEMs) have been adopted worldwide to lower medication expenditure and improve adherence. This study aims to analyse the effect of FCPEMs on patients' medication adherence in Taizhou city, China. Methods: This study was a quasi-experimental study and set treatment and control groups. We extracted Electronic Health Records (EHRs) for hypertension and diabetes 1 year before and after FCPEMs implementation and their medication adherence level assessed by physicians. We applied the propensity score matching (PSM) method to balance the bias between the two groups. Then, the descriptive analysis was used to compare the differences in the reported medication adherence. Using the Difference-In-Differences (DIDs) method, the fixed-effect model with the logistic regression was built to analyse the effects of FCPEMs. Results: 225,081 eligible patients were identified from the original database. In the baseline year, FCPEM covered 39,251 patients. After PSM, 6,587 patients in the treatment group and 10,672 patients in the control group remained. We found that the proportion of patients with high adherence in the treatment group increased by 9.1% (60.8 to 69.9%, P < 0.001) and that in the control group increased by 2.6% (62.5 to 65.2%, P < 0.001). The regression results showed that FCPEMs significantly increased patients' medication adherence (OR = 2.546, P < 0.001). Conclusion: FCPEMs significantly improved medication adherence. Socially disadvantaged individuals might benefit more from continuing FCPEM efforts. Expanding the coverage of FCPEMs to other medicines commonly used in patients with chronic diseases may be a promising strategy to manage chronic diseases and promote patient outcomes.

Prices and Clinical Benefit of National Price-Negotiated Anticancer Medicines in China.

BACKGROUND: High prices of anticancer medicines have increased the economic burden for both patients and health insurance systems. Since 2017, China has implemented national price negotiations for medicines, relying on evidence from health technology assessments. We aim to assess the relation between negotiated price and value of anticancer medicines listed in China's National Reimbursement Drug List (NRDL). METHODS: For all price-negotiated anticancer medicines and corresponding indications listed in the latest NRDL between 2017 and 2020, we collected their clinical outcomes data, including overall survival (OS) and progression-free survival (PFS), in supporting trials. Pearson correlation coefficient was calculated to estimate the association between the daily cost and clinical benefit of each indication. RESULTS: In total, 75 indications of 46 branded anticancer medicines were included for analysis. The median daily costs for the anticancer therapies that had gone through negotiation in 2017-2020 were US$87.6, US$71.8, US$58.9, and US$39.7, respectively. For indications supported by randomized trials, no correlation between daily costs and OS and PFS benefit of the price-negotiated cancer therapies was observed (N = 41, r = -0.05, and N = 49, r = 0.04, respectively). For cancer indications newly listed in NRDL in 2020, the association between their daily cost and OS benefit was -0.78 (N = 4, p = 0.221) and 0.01 (N = 8, p = 0.986) before and after the price negotiation. CONCLUSION: Though the negotiation policy decreased prices of anticancer medicines in China, no statistically significant correlation was observed between their daily costs and clinical benefits. A more transparent and credible pricing approach needs to be established to promote value-based anticancer medicines and healthcare system efficiency.

Clinical Outcome and Medical Cost of Originator and Generic Antihypertensive Drugs: A Population-Based Study in Yinzhou, China.

Background: The substitution of generic drugs can effectively alleviate the rapid growth of drug costs; however, the clinical effectiveness and medical costs of originator products and generics were barely studied in China. Objectives: To compare the effectiveness of antihypertensive drugs and hypertension-related medical costs between originator and generic initiators in Yinzhou, China. Methods: We conducted a population-based retrospective cohort study using the Chinese Electronic Health Records Research in Yinzhou (CHERRY), from July 1, 2011, to December 31, 2018. Hypertension patients initiating with originator products were compared with patients initiating with generic counterparts. We used 1:1 propensity score matching to pair the two groups based on sociodemographic, clinical, and health service utilization variables. Cox proportional regression was adopted to compare the rate of hospitalization for hypertension-related cardiovascular disease between matched originator and generic initiators. Wilcoxon matched-pairs signed-rank test was used to compare annual hypertension-related medical costs. Results: Matched pairs (10,535) of patients were included in the comparative study of originator products and generics, corresponding to seven antihypertensive drugs including amlodipine, felodipine, nifedipine, irbesartan, losartan, valsartan, and metoprolol. The average age of patients included in the analysis was around 60 years (originator vs. generics initiators: from 59.0 vs. 59.1 years in losartan to 62.9 vs. 63.6 years in nifedipine). Higher hospitalization rates among originator initiators were observed for three calcium channel blockers (hazard ratio[95% CI]: amlodipine, 3.18[1.43, 7.11]; felodipine, 3.60[1.63, 7.98]; and nifedipine, 3.86[1.26, 11.81]; respectively). The remaining four out of seven drugs of the clinical endpoint estimates showed comparable outcomes between originator products and generics (hazard ratio[95% CI]: irbesartan, 1.19[0.50, 2.84]; losartan, 1.84[0.84, 4.07]; valsartan, 2.04[0.72, 5.78]; and metoprolol, 1.25[0.56, 2.80]; respectively). Higher median annual hypertension-related medical costs were observed in originator initiators (all p < 0.001), except for metoprolol (p = 0.646). Conclusion: We observed comparable or even better clinical outcomes and less medical cost associated with the use of antihypertensive generics compared to originator counterparts. This could help increase patient and provider confidence in the efficacy of generic medicines to manage hypertension diseases.

Effects of the Full Coverage Policy of Essential Medicines on Inequality in Medication Adherence: A Longitudinal Study in Taizhou, China.

The full coverage policy for essential medicines (FCPEMs) was proposed and implemented in Taizhou city of Zhejiang Province, China, to promote equal access and adherence to medicines. This study aimed to examine the effects of FCPEMs on the income-related inequality in medication adherence among local patients with hypertension or diabetes. We collected electronic health records of patients with hypertension or diabetes of three districts of Taizhou from 2011 to 2016. As the implementation schedule of the FCPEMs varied across districts, we applied a retrospective longitudinal study design and assigned records from 1 year before to 3 years following the implementation of FCPEMs as baseline and follow-up data. We thus generated a dataset with 4-year longitudinal data. The concentration index (CI) and its decomposition method were employed to measure factors contributing to inequality in medication adherence and the role played by FCPEMs. The sample size rose from 264,836 at the baseline to 315,677, 340,512, and 355,676 by each follow-up year, and the proportion of patients taking free medicines rose from 17.6 to 25.0 and 29.8% after FCPEMs implementation. The proportion of patients with high adherence increased from 39.9% at baseline to 51.6, 57.2, and 60.5%, while CI decreased from 0.073 to -0.011, -0.029, and -0.035. The contribution of FCPEMs ranked at 2nd/13, 7th/13, and 2nd/13 after the implementation of FCPEMs. Changes in CI of medication adherence for every 2 years were -0.084, -0.018, and -0.006, and the contribution of FCPEMs was -0.006, 0.006, and 0.007, ranking at 2nd/13, 2nd/13, and 1st/13, respectively. Most changes in CI of medication adherence can be attributed to FCPEMs. The medication adherence of patients with hypertension or diabetes improved after the implementation FCPEMs in Taizhou, although inequality did not improve consistently. In general, FCPEMs could be a protective factor against income-related inequalities in access and adherence to medicines. Future research is needed to investigate the change mechanism and the optimal design of similar interventions.

Health technology assessment-informed pricing negotiation in China: higher negotiated price for more effective targeted anticancer medicines?

BACKGROUND: In China, health technology assessment (HTA) has recently been adopted in pricing negotiation for medicine listing in the National Reimbursement Drug List. At present, how HTA is applied to inform the decision-making process remains underreported. In order to explore how the adoption of HTA was translated into listing and price negotiation results in light of the confidential nature of the negotiating process, this study aimed to compare the negotiated price and the clinical benefit of selected targeted anticancer medicines (TAMs) involved in the 2019 negotiation. MAIN TEXT: Among 16 TAMs successfully negotiated, only four TAMs representing four indication groups had appropriate reference medicines for comparison and were, therefore, included in the analysis. The price and clinical benefit of the four TAMs were compared against one or two reference medicines with the same initial indications. The sales prices for nine TAMs before and after the negotiation were extracted from the centralized medication procurement system. Clinical benefits were evaluated based on evidence from published articles and clinical guidelines. The results suggested that, despite the application of HTA, both rational and irrational decisions had been made about the reimbursement of TAMs in the 2019 negotiation, warranting further investigation. CONCLUSION: While the development and adoption of HTA has seen significant progress in China, actions are needed to ensure that the adoption of HTA is effectively applied in decisions on the reimbursement of medicines.

Influence of Government Price Regulation on the Price, Volume and Spending of Antibiotics in China: A Controlled Interrupted Time Series Study.

BACKGROUND: Chinese government established maximum retail prices for antibiotics listed in China's National Reimbursement List in February 2013. This study aimed to analyze the impact of pharmaceutical price regulation on the price, volume and spending of antibiotics in China. METHODS: An interrupted time series design with comparison series was used to examine impacts of the policy changes on average daily cost, monthly hospital purchase volume and spending of the 11 price-regulated antibiotics and 40 priceunregulated antibiotics in 699 hospitals. One intervention point was applied to assess the impact of policy. RESULTS: After government price regulation, compared to price-unregulated antibiotics, the average daily cost of the price-regulated group declined rapidly (ß=-5.68, P<.001). The average hospital monthly purchase spending of priceregulated antibiotics also decreased rapidly (ß=-0.49, P<.010) and a positive trend change (ß=0.04, P<.001) in average hospital spending of price-unregulated antibiotics was found. CONCLUSION: Government regulation can reduce the prices and spending of price-regulated antibiotics. To control increasing expenditure, besides price caps regulation, factors determining drug utilization also need to be considered in policy designing.

Trends of Negotiated Targeted Anticancer Medicines Use in China: An Interrupted Time Series Analysis.

BACKGROUND: In order to relieve the financial burden of the patients in China, the Ministry of Health (MoH) conducted the first national price negotiation and successfully negotiated three expensive medicines including 2 targeted anticancer medicines (TAMs), icotinib and gefitinib. However, little evidence was available to demonstrate the impact of the national negotiation on TAMs use. The purpose of the study is to evaluate the implementation of the national price negotiation policy in China on TAMs use. METHODS: We used interrupted time series (ITS) design to examine the changes in the daily cost, the monthly hospital purchasing volume and spending of icotinib and gefitinib with pharmaceutical procurement data from 594 tertiary hospitals in 29 provinces of mainland China between January 2015 and July 2017. The period between May and July 2016 was applied to assess the impact of policy. RESULTS: The daily cost of icotinib and gefitinib decreased by 50.08% (P<.001) and 53.89% (P<.001) 12 months after the national negotiation, respectively. In terms of volume, the negotiation was associated with increases in the trend of the monthly hospital purchasing volume of icotinib and gefitinib by 4.87 thousand defined daily doses (DDDs) (P<.001) and 6.89 thousand DDDs (P<.001). However, the monthly hospital purchasing spending of icotinib and gefitinib decreased rapidly by US$0.51 million (P<.010) and US$0.82 million (P<.050) following policy implementation, respectively. CONCLUSION: The first national negotiation had successfully cut off the price of two negotiated TAMs and promoted TAMs use in China. In the future, government should conduct further price negotiations and include more medicines with clinical benefits into reimbursement schemes to alleviate patients' financial burden and promote their access to essential treatment.

Real-world Use of and Spending on New Oral Targeted Cancer Drugs in the US, 2011-2018.

Importance: Launch prices of new cancer drugs in the US have substantially increased in recent years despite growing concerns about the quantity and quality of evidence supporting their approval by the US Food and Drug Administration (FDA). Objective: To assess the use of and spending on new oral targeted cancer drugs among US residents with employer-sponsored insurance between 2011 and 2018, stratified by the strength of available evidence of benefit. Design, Setting, and Participants: In this cross-sectional study, dispensing claims for oral targeted cancer drugs first approved by the FDA between January 1, 2011, and December 31, 2018, were analyzed. The number of patients with drugs dispensed and the total payment for all claims were aggregated by calendar year, and these outcomes were arrayed according to evidence underlying FDA approvals, including pivotal study design (availability of randomized clinical trials) and overall survival (OS) benefit, as documented in drug labels. This study was conducted from July 17, 2019, to July 23, 2021. Main Outcomes and Measures: Annual and cumulative numbers of patients who had dispensing events, and annual and cumulative sums of payment for eligible drugs. Results: Of 37 348 patients who had at least 1 of the 44 new oral targeted drugs dispensed between 2011 and 2018, 21 324 were men (57.1%); mean (SD) age was 64.1 (13.1) years. Most individuals (36 246 [97.0%]) received drugs for which evidence from randomized clinical trials existed; however, a growing share of patients received drugs without documented OS benefit during the study period: from 12.7% in 2011 to 58.8% in 2018. Cumulative spending on all sample drugs totaled $3.5 billion by the end of 2018, of which 96.8% was spent on drugs that were approved based on a pivotal randomized clinical trial. Cumulative spending on drugs without documented OS benefit ($1.8 billion [51.6%]) surpassed that on drugs with documented OS benefit ($1.7 billion [48.4%]) by the end of 2018. Conclusions and Relevance: The findings of this cross-sectional study suggest that drugs used for treatment of cancer without documented OS benefits are adopted in the health system and account for substantial spending.

Outpatient Antibiotic Prescribing Patterns and Appropriateness for Children in Primary Healthcare Settings in Beijing City, China, 2017-2019.

(1) Background: Few studies have focused on antibiotic use and appropriateness in children in primary health institutions (PHIs). This study aimed to identify the patterns and appropriateness of antibiotic use for children in PHIs in Beijing, China. (2) Methods: Outpatient prescriptions of 327 PHIs from 2017 to 2019 for patients <18 years old were collected. Prescriptions were described using quantity indicators. Antibiotics were categorized according to ATC classification J01 and Access, Watch, Reserve grouping. Appropriateness was reviewed by experts using three subtypes of irrational prescriptions (irregular, inappropriate, and abnormal). (3) Results: 20,618 prescriptions were collected in total. The antibiotic prescription rate (APR) was 15.1% (N = 3113). Among antibiotic prescriptions, J01FA Macrolides were the most used (N = 1068, 34.9%). The Watch group constituted 89.0% (N = 2818) of total antibiotic use. Bronchitis (N = 1059, 35.2%) was the most common diagnosis. A total of 292 instances of irrational antibiotic use were identified, with inappropriate prescriptions being the most prevalent subtype (N = 233, 79.8%). (4) Conclusion: Although APR for children in PHIs in Beijing was relatively low, the pattern of antibiotic use differed from other countries. Further studies are needed to optimize antibiotic use for children in PHIs under different levels of economic development.

Antibiotic use and irrational antibiotic prescriptions in 66 primary healthcare institutions in Beijing City, China, 2015-2018.

OBJECTIVES: To identify the patterns of antibiotic use and irrational antibiotic prescriptions in primary healthcare institutions (PHIs) in Dongcheng District of Beijing, China. MATERIALS AND METHODS: All primary healthcare institutions (7 community healthcare centres and 59 community healthcare stations in total) in Dongcheng District were included in the study. Prescription data from January 2015 to December 2018 was derived from the Beijing Prescription Reviewing System of Primary healthcare institutions and analysed retrospectively. The antibiotic prescription rate was calculated and cases of irrational antibiotic prescriptions were identified. RESULTS: We extracted 11,166,905 prescriptions from the database. Only 189,962 prescriptions were included in the study, among which 9167 (4.8%) contained antibiotics. The antibiotic prescription rate fell from 5.2% in 2015 to 4.1% in 2018 while irrational antibiotic prescription rate increased from 10.4 to 11.8%. Acute Bronchitis was the most prevalent diagnosis (17.6%) for antibiotic prescriptions, followed by Unspecified Acute Respiratory Tract Infection (14.4%), Acute Tonsillitis (9.9%), and Urinary Tract Infection (6.4%). Around 10% of the prescriptions for the top 7 diagnoses identified were rated as irrational. Cephalosporins, fluoroquinolones, and macrolides were the most prescribed antibiotics, which accounted for 89.3% of all antibiotic prescriptions. Of all the antibiotic prescriptions, 7531 were reviewed, among which 939 (12.5%) were rated as irrational because of antibiotic use. Among all the irrational prescriptions, prescriptions with inappropriate antibiotic use and dosage accounted for the majority (54.4%). CONCLUSION: Although a relatively low level of antibiotic utilization was found in PHIs in Dongcheng District of Beijing, the utilization patterns differed considerably from developed countries and irrational prescriptions remained. Considering the imbalanced allocation of medical resources between primary healthcare setting and secondary and tertiary hospitals, there need to be more efforts invested in regions with different levels of economic development.

The impacts of government reimbursement negotiation on targeted anticancer medication price, volume and spending in China.

INTRODUCTION: New targeted therapies have changed cancer treatment in the past decades. However, high prices of targeted anticancer medications have increased economic burden for both patients and health insurance systems. In July 2017, China implemented combined medication price negotiation and mandatory reimbursement policies for 15 targeted anticancer medications. This study assesses effects of the policy on hospital procurement prices, volumes and spending. METHODS: Using a quasi-experimental interrupted time series design, we analysed procurement data from the Chinese Medical Economic Information of 789 public hospitals in 30 provinces between January 2016 and September 2018. The intervention group consisted of 15 targeted anticancer medications with negotiated prices in 2017. The comparison group consisted of six targeted anticancer medications without negotiated prices by 2018. The effective date of the policy was September 2017. RESULTS: After the implementation of the 2017 medication price negotiation and reimbursement policy, cost per defined daily dose (DDD) of the 15 targeted anticancer medications dropped US$71.21 on average from an average US$169.24/DDD before (p=0.000). Compared with what would have happened without the intervention, cost/DDD of price-negotiated medications decreased by 48.9% (p=0.000), procurement volumes increased by 143.0% (p=0.000) and hospital medication spending decreased by 6.9% (p=0.146). CONCLUSIONS: The 2017 medication price negotiation and reimbursement policy decreased targeted medication procurement costs per DDD, increased volumes procured and at least temporarily contained spending. These changes should result in better access to and affordability of targeted anticancer medications in China.

Physician patient-sharing relationships and healthcare costs and utilization in China: social network analysis based on health insurance data.

OBJECTIVES: Evidence on physician patient-sharing relationships from developing countries is limited. This study aimed to identify patient-sharing networks among physicians in China and explore the effect of attributes of physician networks on healthcare utilization and costs. METHODS: Retrospective analysis was undertaken based on healthcare claims from Urban Employee Basic Medical Insurance Data spanning the years 2015 to 2018. We identified patients with hypertension and modeled physician patient-sharing networks using social network analysis. Relationships among physicians were further quantified using network measures. We fitted a log-linear model to examine the association between networks and healthcare at the physician level. RESULTS: 29,321 patients, seen by 3,429 physicians from 57 hospitals in one eastern city of China were included. Physicians were connected to 21 other physicians (threshold = 1 shared patients) or 7 other physicians (threshold = 4, 6, or 8 shared patients). Degree and centrality measures of physicians at primary care facilities were significantly lower than those at secondary or tertiary hospitals (p < 0.001). The links between physicians at different hospital grades were weak and patients tended to flow among physicians at the same hospital grade. Compared with a low closeness centrality, a medium level was associated with fewer hospitalization costs and days, and high closeness centrality was accompanied by a sharper decrease (all P < 0.001). CONCLUSIONS: Primary care physicians were located in peripheral positions in China, and the links between primary care facilities and higher-grade hospitals were still weak. Characteristics of physicians' networks and the position of physicians in the network were associated with spending and utilization of services, but not all associations were in the same direction.

Can locally developed me-too drugs aid price negotiation? An example of cancer therapies from China.

Rapid growth in pharmaceutical expenditures and high prices have greatly hampered access to medicines, especially targeted anticancer medicines. Confronted with such difficulties, the Chinese government has put more effort into supporting local research and development of cancer medicines, resulting in locally developed me-too drugs. Since 2016, the government has implemented a central reimbursement-linked drug price negotiation policy aimed at reducing the prices of expensive medicines. Locally developed me-too drugs marketed at lower prices may inject price competition and help negotiate reduced prices of similar internationally-developed products. As an example, we selected 3 tyrosine kinase inhibitors (TKIs) developed for the therapy of advanced non-small cell lung cancer harboring mutations in the epidermal growth factor receptor (EGFR). Descriptive analysis was applied to data from the Chinese Medical Economic Information database to describe the impact on the price and utilization of three TKIs after the introduction of icotinib, a locally developed me-too TKI and two national negotiations regarding the price of EGFR-TKIs in China. After two national negotiations, the daily costs of all three EGFR-TKIs were reduced to around $30. From the first quarter of 2013 to the second quarter of 2016, the market share of the purchasing volume of icotinib, China's locally developed TKI, increased from 13% to 40%, while the market shares of two internationally developed TKIs decreased from 35% to 15% and from 52% to 45%, for erlotinib and gefitinib, respectively. The prices of EGFR-TKIs decreased and China's locally developed TKI accounted for a considerable proportion of market share. Locally developed me-too drugs aid price negotiation by injecting price competition and helping negotiate reduced prices of similar internationally-developed products. Through efforts to develop me-too drugs, combined with national drug price negotiation and reimbursement policies, developing countries might improve access to more affordable targeted cancer therapies.

Does the universal medical insurance system reduce catastrophic health expenditure among middle-aged and elderly households in China? A longitudinal analysis.

BACKGROUND: The Chinese government has made great progress in establishing the universal medical insurance system. This study aimed to analyze whether the universal medical insurance system protected middle-aged and elderly households from catastrophic health expenditure (CHE). METHODS: The data were obtained from the China Health and Retirement Longitudinal Study. We used household as our unit of analysis and CHE was measured as out-of-pocket expenditures ≥ 40% of nonfood household expenditures. Univariate analysis was deployed to examine the impacts of different medical insurance schemes on CHE, and the factors associated with CHE were estimated using a random-effects logit regression model. RESULTS: We identified 10,005, 10,370, and 11,567 households in 2011, 2013, and 2015, respectively, and found 12.9% (2011), 26.6% (2013) and 27.9% (2015) of the households experienced CHE. When compared with no insurance, households enrolled in New Rural Cooperative Medical Insurance Scheme (P = 0.023) were associated with a lower incidence of CHE, but other insurance schemes were not significant. Households with members older than 65 years (P < 0.001), members with chronic diseases (P < 0.001), members with poor self-reported health conditions (P < 0.001), and members receiving health care (P < 0.001) had a higher risk of CHE. Large household size (P < 0.001) and high household income per capita (P < 0.001) were major protective factors to CHE incidence. CONCLUSIONS: Despite China's great stride in the medical insurance coverage, it fell short to provide financial protection against medical expenditure burden. To reduce the risk of CHE, an integrated poverty and elderly-oriented medical insurance system could be put in place to address these problems.
