Objective: Colorectal cancer(CRC) causes a substantial burden of disease in China and the evidence of economic burden triggered is fundamental for priority setting. The aim of this survey was to quantify medical expenditures and the time trends for CRC diagnosis and treatment in China.Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 13 provinces across China. For each eligible CRC patient diagnosed from 2002 to 2011, clinical information and expenditure data were extracted using a uniform questionnaire. All expenditure data were reported in Chinese Yuan(CNY)using 2011 values.Results: Of the 14,536 CRC patients included, the average age at diagnosis was 58.2 years and 15.8% were stageI cases. The average medical expenditure per patient was estimated at 37,902 CNY [95 % confidence interval(95%CI): 37,282-38,522], and the annual average increase rate was 9.2% from 2002 to 2011(P for trend <0.001), with a cumulative increase of 2.4 times(from 23,275 CNY to 56,010 CNY). The expenditure per patient in stages Ⅰ, Ⅱ, Ⅲ and Ⅳ were 31,698 CNY, 37,067 CNY, 38,918 CNY and 42,614 CNY, respectively(P<0.001). Expenditure significantly differed within various subgroups. Expenses for drugs contributed the largest proportion(52.6%).Conclusions: These conservative estimates illustrated that medical expenditures for CRC diagnosis and treatment in tertiary hospitals in China were substantial and increased rapidly over the 10 years, with drugs continually being the main expense by 2011. Relatively, medical expenditures are lower for CRC in the earlier stages. These findings will facilitate the economic evaluation of CRC prevention and control in China. 展开更多

We sought to clarify regional differences in medical expenditures by analyzing the relationship between the specific health examination coverage and medical care expenditure by prefecture of Japan. <strong>Methods:</strong> We used data from the National Database of Health Insurance Claims and Specific Health Checkups (NDB) Open Data Japan (2015) and Overview of 2015 National Medical Expenses to compare medical care expenditure per capita and proportions of persons receiving specific health examination between Japan nationally and individual prefectures. <strong>Results: </strong>National medical expenditures were 42.3 trillion Japanese yen (JPY) (3851 hundred million dollars), with a national per capita rate of JPY347,219 (USD3156). Per capita medical expenditure rates by prefecture ranged from JPY290,900 (USD2645) in Saitama Prefecture to JPY 444,000 (USD4036) in Kochi Prefecture. The proportion of persons receiving specific health examinations was 49.0% for Japan overall and ranged from 39.3% in Hokkaido Prefecture to 63.4% in Tokyo Prefecture. We observed a significant negative correlation between per capita medical expenditures and the proportion of persons receiving specific health examinations (R = 0.553, p < 0.001).<strong> Conclusion: </strong>We found a significant negative correlation between per capita medical expenditures and the proportion of persons receiving health examinations: prefectures with lower expenditures tended to have higher rates of medical examinations. Interventions to increase the proportion of persons receiving specific health examinations by prefecture could reduce per capita medical expenditures and reduce prefectural disparities in expenditures. 展开更多

The intervention of behaviors, including physical activity (PA), has become a strategy for many hospitals dealing with patients with chronic diseases. Given the limited evidence available about PA and healthcare use with chronic diseases, this study explored the association between different levels of PA and annual hospital service use and expenditure for inpatients with coronary heart disease (CHD) in China. We analyzed PA information from the first follow-up survey (2013) of the Dongfeng-Tongji cohort study of 1460 CHD inpatients. We examined factors such as PA exercise volume and years of PA and their associations with the number of inpatient visits, number of hospital days, and inpatient costs and total medical costs. We found that the number of hospital days and the number of inpatient visits were negatively associated with intensity of PA level. Similarly, total inpatient and outpatient costs declined when the PA exercise volume levels increased. Furthermore, there were also significant associations between the number of hospital days, inpatient costs or total medical costs and levels of PA years. This study provides the first empirical evidence about the effects of the intensity and years of PA on hospital service use and expenditure of CHD in China. It suggests that the patients' PA, especially the vigorous PA, should be promoted widely to the public and patients in order to relieve the financial burden of CHD. 展开更多

This study was undertaken to investigate clothing expen-diture patterns of families in Shanghai, and especially the relationship between age of the family and the expendi-tures . Interview data from 292 families in Shanghai were used in analysis. Families were divided into three groups, including the young, middle - aged, and old families. Descriptive analysis and regression were em-ployed. Major findings concern total expenditures of family members as well as the entire family, and expen-ditures on different categories of clothing. Factors which had impacts on clothing expenditures were also investi-gated. It was concluded that age of the families had an impact on expenditures, and the three groups of families had different patterns of clothing consumption. 展开更多

Overweight and obese individuals are at increased risk for many diseases and health conditions, including but not limited to the following: hypertension;osteoarthritis;dyslipidemia;type 2 diabetes;coronary heart disease and stroke. Consequently, individuals who are obese are more likely to use health services and are more likely to use costly health services than non-obese individuals. Between 1987 and 2001, growth in obesity related health expenditures accounted for 27 percent of the growth in inflation-adjusted per capita health care spending. Researchers, popular press and the television news media have paid considerable attention to the effect that farm subsidies have on dietary habits and obesity. Prominent researchers in the field have concluded that US farm subsidies have had a negligible impact on obesity. However, even small increases in obesity rates are associated with higher health care expenditures. The primary intent of this study is to break down the linkages from farm subsidy to health expenditure and shed light on the unintended implications of the farm subsidy program. We find that agricultural subsidies have the potential to influence health care expenditures. 展开更多

In this paper, we analyzed length of stay (LOS) in hospitals and medical expenditures for type 2 diabetes patients. LOS was analyzed by the power Box-Cox transformation model when variances differed among hospitals. We proposed a new test and consistent estimator. We rejected the ho-moscedasticity of variances among hospitals, and then analyzed the LOS of 12,666 type 2 diabetes patients hospitalized for regular medical treatments collected from 60 general hospitals in Japan. The variables found to affect LOS were age, number of comorbidities and complications, introduced by another hospital, one-week hospitalization, 2010 revision, specific-hospitalization-period (SHP), and principal diseases E11.5, E11.6 and E11.7. There were surprisingly large differences in ALOS among hospitals even after eliminating the influence of characteristics and conditions of patients. We then analyzed daily medical expenditure (DME) by the ordinary least squares methods. The variables that affected DME were LOS, number of comorbidities and complications, acute hospitalization, hospital’s own outpatient, season, introduced by another hospital, one-week hospitalization, 2010 revision, SHP, time trend, and principal diseases E11.2, E11.4 and E117. The DME did not decrease after the SHP. After eliminating the influences of characteristics and conditions of patients, the differences among hospitals were relatively small, 12% of the overall average. LOS is the main determinant of medical expenditures, and new incentives to reduce LOS are needed to control Japanese medical expenditures. Since at least 99% of patients require medical care after leaving the hospital, systems that take proper care of patients for long periods of time after hospitalization are absolutely necessary for efficient treatment of diabetes. 展开更多

Background:Missed clinic appointments negatively impact clinic patient flow and health outcomes of people living with HIV(PLHIV).PLHIV likelihood of missing clinic appointments is associated with direct and indirect expenditures made while accessing HIV care.The objective of this study was to examine the relationship between out-of-pocket(OOP)health expenditures and the likelihood of missing appointments.Method:Totally 618 PLHIV older than 18 years attending two HIV care and treatment centres(CTC)in Northern Tanzania were enrolled in the study.Clinic attendance and clinical characteristics were abstracted from medical records.Information on OOP health expenditures,demographics,and socio-economic factors were self-reported by the participants.We used a hurdle model.The first part of the hurdle model assessed the marginal effect of a one Tanzanian Shillings(TZS)increase in OOP health expenditure on the probability of having a missed appointment and the second part assessed the probability of having missed appointments for those who had missed an appointment over the study period.Results:Among these 618 participants,242(39%)had at least one missed clinic appointment in the past year.OOP expenditure was not significantly associated with the number of missed clinic appointments.The median amount of OOP paid was 5100 TZS per visit,about 7%of the median monthly income.Participants who were separated from their partners(adjusted odds ratio[AOR]=1.83,95%confidence interval[CZ]:1.11-8.03)and those aged above 50 years(AOR=2.85,95%CI:1.01-8.03)were significantly associated with missing an appointment.For those who had at least one missed appointment over the study period,the probability of missing a clinic appointment was significantly associated with seeking care in a public CTC(P=0.49,95%CI:0.88-0.09)and aged between>25-35 years(P=0.90,95%CI:0.11-1.69).Conclusion:Interventions focused on improving compliance to clinic appointments should target public CTCs,PLHIV aged between>25-35 years,above 50 years of age and those who are separated from their partners. 展开更多

A more resilient livelihood is increasingly recognized as an efficient way to improve vulnerable households’food security and optimize their dietary decisions.This study quantifies rural household resilience in western China,identifies the three pillars(absorptive capacity,adaptive capacity,and transformative capacity)contribution to resilience,and then establishes the estimated Resilience Capacity Index(RCI)linked with food security and dietary diversity supported by the multiple indicator multiple cause(MIMIC)model.Results show that,despite geographical heterogeneity,the RCI consistently increased from 2015 to 2021.Households with a higher RCI inheriting better capacity to deal with risk and shocks are significantly and positively correlated with increasing food expenditure and diversifying food choices.It can be because resilient households will allocate more money to food expenditure instead of saving for livelihood uncertainty.Thus,policymakers can provide more incentives for rural households to adopt more dynamic and effective risk management strategies.This,in turn,could yield positive spillover effects by preventing human capital loss associated with dietary-related chronic diseases and mortality. 展开更多

Background: Investigate into the medical expenditures of chronic kidney disease (CKD) patients through path analysis method of three consecutive years within a Grade-A tertiary hospital in Beijing to conduct the main influencing factors in diagnosis-related groups (DRGs) grouping of the diagnosis, and reassess the present grouping process to provide information and reference on cost control for hospitals and medical management departments. Methods: Eight hundred and fifty-five inpatient cases whose first diagnosis were defined as CKD in the year 2014-2016 within the hospital were selected as the sample of the study, multiple linear regression and path analysis method were adopted in DRGs grouping process to investigate the main influencing factors of total medical expenditures and DRGs grouping process. Results: The maximum proportion of the medical costs within CKD patients was the costs on treatment, with the highest of 35.3% on the year 2014, the second was the costs on drug, which accounted for 〈30% during consecutive years, and the third was the costs on examination, which accounted for about 20% on average. The main influencing factors of medical expenditures included the type of dialysis, length of hospitalization, the admission of Intensive Care Unit (ICU), and so on. The coefficients toward the effect for total costs were 0.416, 0.376, and 0.094. respectively. Conclusions: It is suggested that the type of dialysis and the admission of ICU were the major influencing factors of inpatient medical expenditures on CKD patients, and should be taken into consideration into the reassessment of DRGs grouping process to realize the localization and generalization of prospective payment system based on DRGs within the regional area and promote the implementation of medical cost control measures to reduce the economic burdens among patients and the society. 展开更多

Rivers are important habitats for wintering waterbirds.However,they are easily influenced by natural and human activities.An important approach for waterbirds to adapt to habitats is adjusting the activity time and energy expenditure allocation of diurnal behavior.The compensatory foraging hypothesis predicts that increased energy expenditure leads to longer foraging time,which in turn increases food intake and helps maintain a constant energy balance.However,it is unclear whether human-disturbed habitats result in increased energy expenditure related to safety or foraging.In this study,the scan sample method was used to observe the diurnal behavior of the wintering Spot-billed Duck(Anas poecilorhyncha) in two rivers in the Xin’an River Basin from October 2021 to March 2022.The allocation of time and energy expenditure for activity in both normal and disturbed environments was calculated.The results showed that foraging accounted for the highest percentage of time and energy expenditure.Additionally,foraging decreased in the disturbed environment than that in the normal environment.Resting behavior showed the opposite trend,while other behaviors were similar in both environments.The total diurnal energy expenditure of ducks in the disturbed environment was greater than that in the normal environment,with decreased foraging and resting time percentage and increased behaviors related to immediate safety(swimming and alert) and comfort.These results oppose the compensatory foraging hypothesis in favor of increased security.The optimal diurnal energy expenditure model included river width and water depth,which had a positive relationship;an increase in either of these two factors resulted in an increase in energy expenditure.This study provides a better understanding of energy allocation strategies underlying the superficial time allocation of wintering waterbirds according to environmental conditions.Exploring these changes can help understand the maximum fitness of wintering waterbirds in response to nature and human influences. 展开更多

Objectives Understanding past trends and forecasting future changes in health spending is vital for planning and reducing reliance on out-of-pocket(OOP)expenses.The current study analyzed health expenditure patterns in India and forecasted future trends and patterns until 2035.Methods Data on health expenditure in India from 2000 to 2019 was collected from the Organisation for Economic Co-operation and Development(OECD)iLibrary and National Health Accounts 2019 databases.Gross domestic product(GDP)data from the World Bank was also utilized.Descriptive statistics analyzed the composition and pattern,while the exponential smoothing model forecasted future health expenditures.Results The findings revealed that expenditure made by OOP is the primary health financing source,followed by government and pre-paid private spending.The percentage of GDP allocated to total health expenditure remains stable,while the per capita health expenditure fluctuates.Variations in expenditure among states are observed,with Karnataka relying heavily on pre-paid private coverage.Future projections suggest a decline in per capita and total health expenditure as a share of GDP,with a slight increase in the government’s share.Pre-paid private expenditure per capita and OOP health expenditure as a share of the total is projected to remain relatively constant but still high in absolute terms.Conclusion The study highlights variations in health spending in India,characterized by high OOP spending,limited public coverage,and a need for investments,and reforms to improve healthcare access and equity. 展开更多

In recent years, there has been global interest in meeting targets relating to energy affordability and security while taking into account greenhouse gas emissions. This has heightened major interest in potential investigations into the use of supercritical carbon dioxide (sCO2) power cycles. Climate change mitigation is the ultimate driver for this increased interest;other relevant issues include the potential for high cycle efficiency and a circular economy. In this study, a 25 MWe recompression closed Brayton cycle (RCBC) has been assessed, and sCO2 has been proposed as the working fluid for the power plant. The methodology used in this research work comprises thermodynamic and techno-economic analysis for the prospective commercialization of this sCO2 power cycle. An evaluated estimation of capital expenditure, operational expenditure, and cost of electricity has been considered in this study. The ASPEN Plus simulation results have been compared with theoretical and mathematical calculations to assess the performance of the compressors, turbine, and heat exchangers. The results thus reveal that the cycle efficiency for this prospective sCO2 recompression closed Brayton cycle increases (39% - 53.6%) as the temperature progressively increases from 550˚C to 900˚C. Data from the Aspen simulation model was used to aid the cost function calculations to estimate the total capital investment cost of the plant. Also, the techno-economic results have shown less cost for purchasing equipment due to fewer components being required for the cycle configuration as compared to the conventional steam power plant. 展开更多

This paper examines the individual financial risk of health care expenditures over time in urban China, .using longitudinal health expenditure data from 2005 to 2007 in Kunshan City, Jiangsu Province, China. We find that the stochastic process of log total health care expenditures is well represented by the sum of an AR(3) process and white noise process. Simulating this model, we find that the urban health insurance system protects enrollees from the risk of catastrophic health care expenditures by bearing the majority of the health care expenditures. However, out-of-pocket health care expenditures represents a considerable risk to an individual's financial status. 展开更多

Background: Renal cell carcinoma (RCC) is the most common type of malignant renal tumors with a growing incidence in tile recent years. This study aimed to investigate the influencing factors and variation trend of hospitalization expenditures among RCC patients in a single-centered hospital in Beijing during 5 consecutive years and to find the major cost items and fluctuation tendency of inpatient medical expenditures. Methods: The inlbrmation of medical expenditures among RCC patients in a Grade-A tertiary hospital during the years 2012-2016 was investigated to find the main cost items and changes affecting the medical cost structure. Gray correlation method was adopted in quantitative analysis to analyze the composition of medical expenditures, and the variation of hospitalization expense structure during tile five years was studied by analyzing the degree of structural variation. Results: The cost item constitution of the hospitalization expenditures among RCC patients was relatively stable in the sample hospital during the past five years. To be specific, drug costs accounted for tile largest proportion of medical expenditures each year, with the highest of 37.81% in 2012, and showed a slowly declining tendency in the coming years. The cost item with the highest correlation degree ~as drug costs, with the value of 1.0000; followed by the costs of surgeries, 0.8423. Furthermore, drug costs shared the largest proportion (40.95%) of structural variation, followed by the costs of surgeries (18.35%). Conclusions: Drug costs are the major influencing factors of the hospitalization expenditures among RCC patients. Thus, reasonable control on excessive drugs as well as the standardization of the diagnosis and treatment behaviors is conducive in reducing medical expenditures as well as easing patients' economic burdens. Besides, the positive growth on surgery costs suggests that the labor value of medical staffs has been gradually recognized. 展开更多

Aiming to control rising medical expenditures and help improve China's healthcare systems, this study examined whether a cap-based medical insurance scheme with shared financial interest between the insurance and healthcare providers is effective in containing hospitals' C-section medical expenditures. We used 6547 caesarean delivery case records from a teaching tertiary-level general public hospital located in Wuxi, China (2004-2013), and used the Chow test to investigate the possibility of significant variation in mean medical expenditures for caesarean deliveries pre- and post-reform. We also used paired sample t-tests and linear regression models to compare the mean medical expenditures between insured and uninsured women undergoing caesarean delivery during the post-reform period. After the scheme's implementation, medical expenditures for caesarean deliveries declined and the medical expenditures of women covered by the scheme were significantly lower than those of uninsured patients. These findings indicated the scheme's effectiveness in minimizing caesarean delivery expenditures. The cap-based medical insurance scheme with shared financial interest between insurance and healthcare providers would likely steer healtbcare providers' behaviors in a more cost-effective direction. 展开更多

Objective: Cervical squamous intraepithelial lesion(SIL) and cervical cancer are major threats to females' health and life in China, and we aimed to estimate the economic burden associated with their diagnosis and treatment.Methods: A nationwide multicenter, cross-sectional, hospital-based survey was conducted in 26 qualified hospitals across seven administrative regions of China. We investigated females who had been pathologically diagnosed with SIL and cervical cancer, and included five disease courses(“diagnosis”, “initial treatment”,“chemoradiotherapy”, “follow-up” and “recurrence/progression/metastasis”) to estimate the total costs. The median and interquartile range(IQR) of total costs(including direct medical, direct non-medical, and indirect costs), reimbursement rate by medical insurance, and catastrophic health expenditures in every clinical stage were calculated.Results: A total of 3,471 patients in different clinical stages were analyzed, including low-grade SIL(LSIL)(n=549), high-grade SIL(HSIL)(n=803), cervical cancer stage ⅠA(n=226), ⅠB(n=610), ⅡA(n=487), ⅡB(n=282), Ⅲ(n=452) and Ⅳ(n=62). In urban areas, the estimated total costs of LSIL and HSIL were $1,637.7(IQR:$956.4-$2,669.2) and $2,467.1(IQR:$1,579.1-$3,762.3), while in rural areas the costs were $459.0(IQR:$167.7-$1,330.3) and $1,230.5(IQR:$560.6-$2,104.5), respectively. For patients with cervical cancer stage ⅠA,ⅠB, ⅡA, ⅡB, and Ⅲ-Ⅳ, the total costs were $15,034.9(IQR:$11,083.4-$21,632.4), $19,438.6(IQR:$14,060.0-$26,505.9), $22,968.8(IQR:$16,068.8-$34,615.9), $26,936.0(IQR:$18,176.6-$41,386.0) and $27,332.6(IQR:$17,538.7-$44,897.0), respectively. Medical insurance covered 43%-55% of direct medical costs for cervical cancer patients, while the coverage for SIL patients was 19%-43%. For most cervical cancer patients, the expense was catastrophic, and the extent of catastrophic health expenditure was about twice large for rural patients than that for urban patients in each stage.Conclusions: The economic burden of SIL and cervical cancer in China is substantial, with a significant proportion of the costs being avoidable for patients with LSIL. Even for those with medical insurance, catastrophic health expenditures are also a major concern for patients with cervical cancer, particularly for those living in rural areas. 展开更多

The overly rapid expansion of fiscal expenditure is an issue the government should take seriously.There are two major causes for the expansion of fiscal expenditure--stress caused by the demand for public goods and stress caused by the features of the administrative system.The influence of the administrative system on fiscal expenditure is demonstrated through the following aspects--the definition of government functions,the development concept of government as well as hierarchies and department setting of governments.The features of China’s administrative system strongly boost the expansion of fiscal expenditure.It is displayed through the concept of rapid development at all government levels,relatively broad definition of government functions,the manifold departments and multi-level settings in the government.The Chinese governments should attach great importance to this issue and take proper measures to relieve the conflict.Some suggested measures include weaving appropriate capital restrictions into government planning,improving the methods of setting targets in planning,building a coordination mechanism for departmental budgets,practicing expenditure budget performance evaluation and releasing the results,as well as adjusting the hierarchical setting of governments. 展开更多

Facing rapid social and economic transformation,China has taken steps to extend and strengthen the Minimum Living Standard Scheme(MLSS).The MLSS is a social assistance programme which initially focused on urban poverty,but later will extend to the rural inhabitants.As the extension of the MLSS,the questions how many poor there are and how much MLSS will cost arise immediately.In line with the data from National Bureau of Statistics(NBS)and Ministry of Civil Affairs(MOCA),this paper estimates different types of poor and reckons how much Chinese government will expenditure.The author also outlines the government financial capabilities on MLSS and discusses the related lessons. 展开更多
