Can a global budget improve health care efficiency? Experimental evidence from China.

Health care in China suffers from substantial allocative inefficiency in the delivery system and technical inefficiency within hospitals. To ameliorate this problem in rural areas, the Analysis of Provider Payment Reforms on Advancing China's Health (APPROACH) project shifted the payment method of China's rural health insurance scheme for county hospitals from fee-for-service to a novel global budget. In particular, APPROACH global budget incentivized system-level allocative efficiency by reimbursing county hospitals at higher tariffs for gatekeeping and averting out-of-county (OOC) admissions among local patients they could treat. APPROACH conducted a large-scale randomized controlled trial of the global budget in 56 counties (22 million enrollees) of Guizhou province during 2016-2017. Applying randomization inference to claims data, we find a significant shift of inpatient utilization and expenditure from OOC hospitals to county hospitals. At county hospitals, average expenditure per admission and length of stay decreased, though not significantly. Effects on readmissions show no clear sign of compromised quality. We further find limited effect heterogeneity with respect to treatment and hospital characteristics. Overall, APPROACH global budget may offer a framework for improving health care efficiency without sacrificing quality.

Economic Burdens for Treatment of Patients With Type 2 Diabetes in North Thailand: A Hospital-Based Observational Study.

PurposeDiabetes and its complications pose an economic burden to healthcare systems, family, and society. Therefore, this study aimed to estimate the real-world financial burden of type 2 diabetes (T2D) treatment, complications, and cardiovascular death.Materials and MethodsAn electronic database of the largest university-affiliated hospital in the North of Thailand was retrieved for a 10-year period (2009-2019). We used the International Classification of Disease 10th Revision codes of diabetes and complications to obtain relevant patient records. All included records based on the inclusion and exclusion criteria were analyzed. Expenditures for diabetes treatment, complications, and cardiovascular death for two years were reported as mean, standard deviation, median, and interquartile range.ResultsOf a total of 9,161 patient records, the average age of patients was 57.8 ± 12.7 years. The average total outpatient cost was THB 22,874 ± 38,066 (US$ 759 ± 1,264) for the first year and THB 23,462 ± 34,441 (US$ 779 ± 1,143) for the second year. The average inpatient expenditure was THB 160,790 ± 411,607 (US$ 5,338 ± 13,666) for the first year and THB 181,804 ± 190,257 (US$ 6,036 ± 6,317) for the second year. Drug was the main component for outpatient expenditure while surgery was the main component for inpatient expenditure. Diabetes patients with complications incurred a greater cost of treatment than those without complications. Cardiovascular death led to about seven times higher cost of treatment than the average total cost of diabetes treatment. Heart failure complications (THB 846,345 ± 752,884 or US$ 28,099 ± 24,996) had the highest inpatient costs compared with other complications in the first year. Stroke complications (THB 71,927 ± 143,414 or US$ 2,388 ± 4,761) had the highest outpatient costs compared with other complications. In general, the first-year expenditure was higher than the second year for all complications.ConclusionsDiabetes incurs a substantial financial burden resulting from its complications. Effective management of diabetes with a multi-sectoral effort from government, providers, patients, and private is required.

Healthcare for Patients with Hepatitis B Virus: Analysis of 367 381 Inpatient Cases in China.

Hepatitis B virus (HBV) infection, which has been recognized as an international public health challenge, has caused significant morbidity for the entire world. This research focused on patients with HBV in China to examine health utilization and expenses. Patients hospitalized with HBV from 2017 to 2019 in tertiary hospitals in Hubei, a province located in central China, were selected as the study population. Healthcare information was collected from the provincial inpatient electronic system database. Univariate and regression analyses were performed to describe the basic situation of healthcare services and determine the influencing indicators of inpatient service expenditure. A total of 367 381 cases of HBV infection were identified in the study area. Most of these cases were patients who were married (90.2%) and males (63%). With the great efforts by the universal coverage of the basic medical insurance (BMI) in China, the increasing rate of inpatient hospitalization for HBV was 3.5 times higher than that of the total inpatient health service cases in the study area. The average age of this group was 52.84±14.10 years and 11.1% of patients paid for their own medical expenditures without insurance. The average length of stay (LOS) was 11.10 days, and the average cost per patient was 15 712.05 RMB. Both values were higher than the average level in study area. Gender, marital status, career, payment type, and kind of hospitals significantly influenced healthcare utilization. Males and the elderly might incur higher healthcare costs than their counterparts. The BMI operated by government has played a role in the utilization release of health services for HBV carriers. However, researchers must pay more attention to the continuing increase in the medical expenses of this group.

A prospective observational study exploring the association of comorbid chronic health conditions with total healthcare expenditure in people with mental health conditions in an Asian setting

BackgroundIt is pertinent to focus on chronic medical condition (CMC) comorbidity with mental health conditions (MHC) as their co-occurrence has significant cost and health implications. However, current evidence on co-occurrence of MHC with CMC is mixed and mostly from Western settings. Therefore, our study aimed to (i) describe the association between MHC and total healthcare expenditure, (ii) examine the association between CMC and total healthcare expenditure and (iii) examine determinants of total and different types of healthcare expenditure in respondents with and without MHC in an Asian setting.MethodsThe data from Singapore Mental Health Study (SMHS) 2016, a nationwide epidemiological survey, were linked with the National claims record (from 2017 to 2019). Multivariable Generalized Linear Models (GLM) were used to examine the association between MHC and total and different types of healthcare expenditure.ResultsA total of 3077 survey respondents were included in current analysis. Respondents with MHC had a lower mean age of 38.6 years as compared to those without MHC (47.1 years). MHC was associated with increased total healthcare expenditure after adjusting for covariates (b = 0.508, p < 0.05). In respondents with MHC, presence of CMC increased the total healthcare expenditure by 35% as compared to 40% increase in those without MHC. Interestingly, 35–49 years age group with MHC had almost 3 times higher total healthcare expenditure and 7.5 times higher inpatient expenditure as compared to the 18–34 years age group.ConclusionOur study highlights variations in association of CMC and age with total healthcare expenditure in those with versus without MHC in an Asian setting. Practical recommendations include appropriate planning and resource allocation for early diagnosis and management of MHC, proactive screening for CMC in those with MHC and addressing the dual issues of treatment gap and stigma to facilitate early help seeking and prevent episodic, costly healthcare utilization.

Number-dependent association of potentially inappropriate medications with clinical outcomes and expenditures among community-dwelling older adults: A population-based cohort study.

The aim of this study was to investigate the prevalence of potentially inappropriate medication (PIM) prescribing and its number-dependent association (PIM = 1, 2, ≥3) with all-cause hospitalizations, emergency department (ED) visits, and medication expenditures in Beijing, China. A retrospective cohort analysis was conducted to analyse PIM prescribing in community-dwelling older adults aged ≥65 years within the Beijing Municipal Medical Insurance Database (data from July to September 2016). The prevalence of PIMs was estimated based on the 2015 Beers Criteria. Logistic models were utilized to investigate the associations between PIM use and all-cause hospitalizations and ED visits. Generalized linear models with the logic link and gamma distribution were used to analyse associations between PIM use and medication expenditures. Among the 506 214 older adults, the prevalence of PIM was 38.07%. After adjusting for covariables, prescribing two and three or more PIMs was associated with increased risks of hospitalizations (PIM = 2: odds ratio [OR] 1.34, 95% confidence interval [CI]: 1.22-1.47; PIM ≥ 3: OR = 1.47, 95% CI: 1.32-1.63) and ED visits (PIM = 2: OR = 1.29, 95% CI 1.12-1.48; PIM ≥ 3: OR = 1.23, 95% CI: 1.04-1.44). Exposures to two and three or more PIMs were associated with higher medication expenditures for inpatient visits (PIM = 2: incidence rate ratio [IRR] = 1.08, 95% CI 1.01-1.16; PIM ≥ 3: IRR = 1.18, 95% CI: 1.08-1.28). Vasodilators were the most frequent PIM prescribing group among patients who were hospitalized or had to visit the ED. PIMs were prescribed at a high rate among community-dwelling older adults in Beijing. Two or more PIMs were associated with increased risks of hospitalizations, ED visits, and increased inpatient medication expenditures. Effective interventions are needed to target unnecessary and inappropriate medications in older adults.

Associations of Chinese diagnosis-related group systems with inpatient expenditures for older people with hip fracture

BackgroundHip fracture is frequent in older people and represents a major public health issue worldwide. The increasing incidence of hip fracture and the associated hospitalization costs place a significant economic burden on older patients and their families. On January 1, 2018, the Chinese diagnosis-related group (C-DRG) payment system, which aims to reduce financial barriers, was implemented in Sanming City, southern China. This study aimed to evaluate the associations of C-DRG system with inpatient expenditures for older people with hip fracture.MethodsAn uncontrolled before-and-after study employed data of all the patients with hip fracture aged 60 years or older from all the public hospitals enrolled in the Sanming Basic Health Insurance Scheme from January 1, 2016 to December 31, 2018. The ‘pre C-DRG sample’ included patients from January 1, 2016 to December 31, 2017. The ‘post C-DRG sample’ included patients from January 1, 2018 to December 31, 2018. A propensity score matching analysis was used to adjust the difference in baseline characteristic parameters between the pre and post samples. Data were analyzed using generalized linear models adjusted for the demographic, clinical, and institutional factors. Robust tests were performed by accounting for time trend, the fixed effects of the year and hospitals, and clustering effect within hospitals.ResultsAfter propensity score matching, we obtained two homogeneous groups of 1123 patients each, and the characteristic variables of the two matched groups were similar. We found that C-DRG reform was associated with a 19.51% decrease in out-of-pocket (OOP) payments (p < 0.001) and a 99.93% decrease in OOP payments as a share of total inpatient expenditure (p < 0.001); whereas total inpatient expenditure was not significantly associated with the C-DRG reform. All the sensitivity analyses did not change the results significantly.ConclusionThe implementation of C-DRG payment system reduced both the absolute amount of OOP payments and OOP payments as a share of total inpatient expenditure for older patients with hip fracture, without affecting total inpatient expenditure. These results may provide significant insights for policymakers in reducing the financial burden on older patients with hip fracture in other countries.

Characterizing Potentially Preventable Hospitalizations of High-Cost Patients in Rural China.

IntroductionHigh-cost patients are characterized by repeated hospitalizations, and inpatient cost accounts for a large proportion of their total health care spending. This study aimed to assess the occurrence and costs of potentially preventable hospitalizations and explore contributing factors among high-cost patients in rural China.MethodsWe examined a population-based sample of patients using the 2016 New Rural Cooperative Medical Scheme in Dangyang city, China. Eighteen thousand forty-three high-cost patients were identified. A validated tool and logistic regression analysis were used to determine preventable hospitalizations and their patient-level and supply-side factors.ResultsHigh-cost patients were older (average age of 54 years) than non-high-cost patients (50 years) and more likely to come from poverty-stricken families. The occurrence of preventable hospitalization was 21.65% among high-cost patients. The proportion of preventable inpatient cost in total inpatient and outpatient expenditure among high-cost patients (5.81%) was lower than that of non-high-cost patients (7.88%) but accounted for 75.87% of the overall preventable inpatient cost. High-cost patients with more hospitalizations were more likely to experience preventable hospitalization, and those with heart failure, COPD, diabetes and mixed conditions were at a higher risk of preventable hospitalization, while those with more outpatient visits were less likely to show preventable hospitalization.ConclusionsThe occurrence of preventable hospitalization among high-cost patients in rural China was sizeable. The preventable inpatient cost of the overall population was concentrated among high-cost patients. Interventions such as improving preventive care and disease management targeting high-cost patients within counties may improve patients' health outcomes and quality of life and reduce overall preventable inpatient cost.

Out-of-Pocket Health Care Expenditure and Poverty Impact in a Fragile Indian State of Assam

Out-of-Pocket (OOP) expenditure on health care is one of the debilitating factors in pushing households into poverty. Households, especially the lower income groups and which do not have security measures like medical insurance, are the worst sufferers when faced with health shocks. Conventional methods of poverty estimation do not take into account health care consumption expenditure, which might understate the poverty headcount. In this study, poverty headcount and impoverishing effects of OOP health care expenditure have been analysed. The data have been collected from Chirang district of Indian state of Assam. The state is a fragile state due to ethnic violence, militancy and natural calamities like flood that the region has been experiencing for decades. The recall period for the inpatient care is 365 days, and six months for outpatient care. The poverty headcount is the difference between post Hp and pre Hp. The pre-payment (i.e. pre-OOP) ‘poverty headcount’ is calculated by comparing household’s consumption expenditure gross of payments for health care with the poverty line defined by the planning commission of India (2001). The post-OOP payment ‘poverty headcount’ is computed by netting out health care payments from a household’s consumption expenditure and then comparing with the poverty line. The intensity of poverty has been estimated with the help of the methods introduced by Wagstaff and Doorslaer (2003). The higher income households make higher OOP expenditure than the lower income households. The burden of OOP is higher on the lower income households because the proportion of OOP expenditure to total income of households is higher amongst the poor households compared to higher income households. OOP expenditure pushed households into poverty. This is more serious with the inpatient care compared to the OOP expenditure on outpatient care. The poverty gap or the intensity of poverty of the overall OOP expenditure is Rs. 279.28, which varies between outpatient and inpatient OOP expenditure.

Expenditures in Young Adults with Hodgkin Lymphoma: NCI-Designated Comprehensive Cancer Centers versus Other Sites.

Outcomes among Hodgkin lymphoma (HL) patients diagnosed between 22 and 39 years are worse than among those diagnosed <21 years, and have not seen the same improvement over time. Treatment at an NCI-designated Comprehensive Cancer Center (CCC) mitigates outcome disparities, but may be associated with higher expenditures. We examined cancer-related expenditures among 22- to 39-year-old HL patients diagnosed between 2001 and 2016 using deidentified administrative claims data (OptumLabs Data Warehouse; CCC: n = 1,154; non-CCC: n = 643). Adjusting for sociodemographics, clinical characteristics, and months enrolled, multivariable general linear models modeled average monthly health-plan paid (HPP) expenditures, and incidence rate ratios compared CCC/non-CCC monthly visit rates. In the year following diagnosis, CCC patients had higher HPP expenditures ($12,869 vs. $10,688, P = 0.001), driven by higher monthly rates of CCC nontreatment outpatient hospital visits (P = 0.001) and per-visit expenditures for outpatient hospital chemotherapy ($632 vs. $259); higher CCC inpatient expenditures ($1,813 vs. $1,091, P = 0.001) were driven by 3.1 times higher rates of chemotherapy admissions (P = 0.001). Out-of-pocket expenditures were comparable (P = 0.3). Young adults with HL at CCCs saw higher health-plan expenditures, but comparable out-of-pocket expenditures. Drivers of CCC expenditures included outpatient hospital utilization (monthly rates of non-therapy visits and per-visit expenditures for chemotherapy). Higher HPP expenditures at CCCs in the year following HL diagnosis likely reflect differences in facility structure and comprehensive care. For young adults, it is plausible to consider incentivizing CCC care to achieve superior outcomes while developing approaches to achieve long-term savings.

Magnitude and determinants of inpatient health expenditure among the elderly in India.

As India is experiencing both the epidemiological and demographic transition, the grey population is expected to incur huge expenditure on health care, especially hospitalization expenditure, in the coming decades. The present study, thus, examines the magnitude of different types of inpatient health expenditure (medical, non-medical, total and out-of-pocket expenditure) and factors affecting them among the Indian elderly, using a health expenditure model empirically tested by the World Health Organization. Data were drawn from the 75th Round of the Health Survey conducted by the National Sample Survey Office, Government of India. In addition to basic descriptive statistics, the study employs a two-stage least square and a generalized linear model with log-link and gamma distribution to conduct the econometric analysis. The study finds that higher income, education, and household size, diseases like cancer, treatment involving surgery, poor physical mobility, and the elderly opting for packages involve higher inpatient health spending, while both private and social health insurance tends to reduce the same. So, a thrust on insurance-financed health systems may reduce health spending among the elderly. In this context, the study suggests that a disease-specific policy is required for the elderly along with ensuring state-of-the-art treatment facilities for them in public hospitals for critical ailments.

Impact of Informal Care on Health Care Utilization Among Older People in China

Population aging has become a challenge to long-term care and health care for the society. Using China as a case study, this paper assesses allocative efficiency of resources in informal care and health care, to explore the effectiveness of the policy, i.e., encouraging informal care as a more cost-effective way to reduce public health care spending. Drawing data from the 2011, 2014, and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey, this study examines the impact of informal care on utilization of health care as well as amount of health care expenditures among older people with functional limitations in China. Using random effects model with instrumental variable approach, our findings suggest that informal care significantly reduces the utilization of health care, primarily by reducing the utilization of outpatient care. However, informal care significantly increases the amount of inpatient care expenditures for inpatient care users. We do not observe significant association between informal care and amount of outpatient care expenditures for outpatient care users. This study highlights a pressing need for the Chinese government to support informal caregivers by taking economic values of informal caregiving into consideration, and to improve efficiency in inpatient care by a more integrated resource allocation mechanism

Multi-Layered Catastrophic Health Spending of Inpatient Women by Broad Group of Diseases in India

Healthcare for Indian women needs prioritizing, as they continue to face social and economic discrimination over their healthcare, often with high out-of-pocket payments. The study examines the amount inpatient women have to pay for treatment of major diseases, re-classified into four groups as infectious, reproductive, non-communicable diseases (NCDs), and disabilities &amp; injuries, across the country to comprehend the extent of catastrophic health spending (CHS) they experienced. The study is based on India’s 75th round of the National Sample Survey (NSS), i.e., Household Social Consumption: Health (2017-2018), consisting of 26,938 inpatient women aged 12 and above from India's urban and rural areas. We examine the prevalence of the four categories of diseases by individual, household, community, and healthcare characteristics. Expenditure estimates were derived from cross-tabulation, followed by binary logistic regression to assess the association between covariates and inpatient expenditures for the diseases. Indian women are more likely to be hospitalized for infectious diseases (43%), but the burden of CHS (overall) is highest for disabilities and injuries (INR 24,414), followed by NCDs (INR 23,053). Duration of hospitalization and possession of health insurance by women indicate maximum variation with medical spending. Almost 97% of women have incurred out-of-pocket expenditure on hospitalization, from which we identify three layers of CHS. A substantial proportion of women (23 to 50%) experienced CHS, i.e., up to 0-10%, 11-30%, and &gt;30%, which varies distinctively by place of residence and across the six regions. Covariates like age, economic status, and healthcare are highly significant and associated with disease-wise CHS thresholds. Women in India face divergent financial hardships for healthcare. Given the heterogeneity of morbidities and socio-economic characteristics, the need for women-sensitive public health services and interventions are evident.

Differentials in private and public healthcare service utilization in later life: do gender and marital status have any association?

ABSTRACT The present study investigates whether the differentials in private and public inpatient healthcare utilization are associated with marital status for men and women aged 60 years and above in India. Binary logistic regression was applied to examine the association of private and public inpatient healthcare utilization with the marital status of the elderly. The study found that widowed men and women generally used public healthcare for hospitalization, while married men and women preferred private healthcare. Our findings also indicated that private inpatient health services expenditure was higher for married elderly than widowed elderly. After controlling all covariates, widowhood was significantly associated with higher use of public healthcare services for women but not for men. India’s current health care policy and program may be required to focus on improving the infrastructure quality of current public healthcare systems. It also needs to be favorable for vulnerable sections of society, especially widowed women, to avail better treatment at an affordable cost.

Cost Control of Treatment for Cerebrovascular Patients Using a Machine Learning Model in Western China.

Background Cerebrovascular disease has been the leading cause of death in China since 2017, and the control of medical expenses for these diseases is an urgent issue. Diagnosis-related groups (DRG) are increasingly being used to decrease the costs of healthcare worldwide. However, the classification variables and rules used vary from region to region. Of these variables, the question of whether the length of stay (LOS) should be used as a grouping variable is controversial. Aim To identify the factors influencing inpatient medical expenditure in cerebrovascular disease patients. The performance of two sets of classification rules, and the effects of the extent of control of unreasonable medical treatment, were compared, to investigate whether the classification variables should include LOS. Methods Data from 45,575 inpatients from a Healthcare Security Administration of a city in western China were used. Kruskal–Wallis H tests were used for single-factor analysis, and multiple linear stepwise regression was used to determine the main factors. A chi-squared automatic interaction detector (CHAID) algorithm was built as a decision tree model for grouping related data. The intensity of oversupply of service was controlled step by step from 10% to 100%, and the performance was calculated for each group. Results The average hospitalization cost was 1,284 US dollars, and the total was 51.17 million US dollars. Of this, 43.42 million were paid by the government, and 7.75 million were paid by individuals. Factors including gender, age, type of insurance, level of hospital, LOS, surgery, therapeutic outcomes, main concomitant disease, and hypertension significantly influenced inpatient expenditure (P < 0.05). Incorporating LOS, the patients were divided into seven DRG groups, while without LOS, the patients were divided into eight DRG groups. More clinical variables were needed to achieve good results without LOS. Of the two rule sets, smaller coefficient of variation (CV) and a lower upper limit for patient costs were found in the group including LOS. Using this type of economic control, 3.35 million US dollars could be saved in one year.

The spillover effect of fiscal environmental protection spending on residents' medical and healthcare expenditure: evidence from China.

The Chinese government has not only been increasing investments in environmental protection, improving the quality of the ecological environment, but has also been focusing on curbing the excessive growth of medical and healthcare expenses so as to ease the economic burden of China's residents. Both aspects are significant concerns worldwide and have received much research attention individually, but the relationship between government environmental protection expenditure and residents' medical and healthcare expenditure remains unclear. Based on panel data from 31 provinces in China from 2007 to 2019, this paper empirically reveals that fiscal environmental protection expenditure is significantly negatively correlated with per capita medical and healthcare expenditure of residents (including outpatient expenditure and inpatient expenditure). This study shows that increasing the fiscal environmental protection expenditure can help curb the rising level of residents' medical and healthcare expenditure. In addition, the results of heterogeneity analysis indicate that the above relationship is stronger in provinces with a relatively low level of economic development or low proportion of the population over 65years old. Management implications are discussed.

Trends in healthcare expenditures and resource utilization among a nationally representative population with opioids in the United States: a serial cross-sectional study, 2008 to 2017

BackgroundPrevious reports on healthcare costs and expenditures associated with populations prescribed an opioid primarily focused on populations who chronically use opioids or have opioid use disorder. However, studies that characterize the healthcare and expenditures costs among the wider number of people prescribed opioids in a nationally representative population are unavailable. We sought to characterize the healthcare costs and expenditures associated with a population prescribed an opioid in the U.S. from 2008 to 2017.MethodsA serial cross-sectional design was used to compare the economic burden of adult household respondents who were prescribed and not prescribed an opioid using pooled data from the Medical Expenditure Panel Survey (MEPS) between 2008 and 2017. Respondents with an opioid prescription were matched to respondents without an opioid prescription using propensity score match methods with survey weights. Two-part generalized linear models were used to estimate the survey-weighted annual healthcare expenditures and resource utilization adjusting for multiple covariates. Additionally, 10-year trend comparisons between the groups were performed. Costs were adjusted to 2019 US dollars.ResultsThere was a weighted total of 31,696,671 respondents with an opioid and 31,536,639 respondents without an opioid after propensity score matching. The sample had a mean (SD) age of 50.63 years (18.03), 58.9% females, and 81.6% Whites. Total annual economic burden among RPOs was $524 billion. Annual total expenditures per respondent with and without an opioid were $16,542 and $7067, respectively (P < 0.001). Similarly, adjusted prescription, outpatient, emergency department, and inpatient expenditures were significantly higher for respondents with an opioid compared to respondents without an opioid. Average annual increases in expenditures were significantly greater among respondents with an opioid compared to respondents without an opioid for total (+$185; 95% CI: $37–$334) and prescription (+$78; 95% CI: $28–$128) expenditures. There were no differences in the average annual trends for outpatient, emergency department, and inpatient expenditures between respondents with and without an opioid.ConclusionsRespondents with an opioid prescription had higher healthcare expenditures and resource utilization compared to respondents without an opioid prescription from 2008 to 2017. Specifically, significant annual increases were observed for total and prescription expenditures. Additionally, 10-year trends in total and prescription expenditures were higher among respondents with an opioid than respondents without an opioid.

Payment mechanism and hospital admission: New evidence from Thailand healthcare reform

In 2007, Thailand's Civil Servant Medical Benefit Scheme (CSMBS), one of the three main public health insurers, adopted a new payment mechanism for hospital admission. There has been a shift from fee-for-service toward Diagnostic Related Group (DRG)-based payment that transfers financial risk from the government to health care providers. This study investigates the effects of this policy change on hospital admission, frequency of admission, length of stay (LOS), type of hospital admitted, and out-of-pocket (OOP) inpatient medical expenditure. By employing nationally representative micro-level data (Health and Welfare surveys) and difference-in-difference approach, this study finds a 1 percentage point decline in hospitalization, a 10% higher chance of admission at community hospitals (the lowest level inpatient public health care facility), and a 7% less chance of admission at higher level public health care facilities like general hospitals. No significant change was observed in LOS, frequency of admission, or OOP inpatient medical expenditure associated with the post-2007 payment mechanism change. Our results emphasize the effectiveness of a close-ended payment mechanism for health care in developing countries. This study also adds to the limited literature on using micro-level data to investigate payment mechanism change in the context of low- and middle-income countries.

Health costs of women with chronic overlapping pain conditions by opioid and complementary and integrative health use.

To estimate differences in average annual health care expenditures of adult women with chronic overlapping pain conditions (COPCs) by pain treatment modality as follows: (1) no long-term opioid or complementary and integrative health (CIH) use; (2) CIH only use; (3) long-term opioid only use; and (4) long-term opioid and CIH use. Cross-sectional Medical Expenditure Panel Survey data (2012-2016). We estimated differences between average annual expenditures of adult women with COPCs by their use of long-term opioids and CIH modalities. Generalized linear regression with a log link function was used to estimate adjusted marginal effects in annual expenditures. The distribution family was chosen based on Modified Park Tests. We controlled for pain severity, patient demographic characteristics, physical limitations, comorbidities, mental health, insurance status, physical therapy use, and census region. We also employed propensity-score based marginal mean weighting through stratification to balance our treatment groups on observed covariates. We identified adult women (>17 years) with one or more self-reported COPC using 3-digit International Classification of Diseases (ICD)-9/10-Clinical Modification (CM) codes (N= 9169) and categorized their use of CIH and long-term opioids. Compared to women without long-term opioid or CIH use, CIH only use was significantly associated with lower inpatient expenditures (-$947 [-$1699, -$196]; p-value < 0.01), higher office-based expenditures ($1345 [$944, $1746]; p-value < 0.001), and higher patient out-of-pocket expenditures ($628 [$409, $848]; p-value < 0.001). Long-term opioid use, alone or in combination with CIH, was significantly associated with higher expenditures (p-value < 0.05) in total and across all utilization categories compared to women without any long-term opioid or CIH use. Our results indicate that CIH treatment approaches for chronic pain have the potential to be utilized without increasing overall costs. Future research should further examine the role of CIH modalities in achieving cost-effective pain management that reduces avoidable opioid use.
