Older adults 's hospitalizational costs and burden study in China--analysis from CHARLS data 2018.

Objective: The aging Chinese population is driving up health care costs, with hospitalizational accounting for a large portion of total health care costs. By 2012, hospitalization costs for people over 60 years of age exceeded outpatient costs, marking a change in the allocation of medical resources. Further research is needed on the factors influencing changes in hospitalizational costs and burden. This paper examines the costs and burden of hospitalization for older adults from a micro perspective, providing new evidence to explain how social, medical, family, personal, and geographic factors affect them. Methods: Utilizing data from the 2018 China Health and Retirement Longitudinal Study (CHARLS), a linear regression model was constructed to investigate the impact of various factors on the hospitalization costs and burden among the older adult in China. To ensure the heterogeneity of the results, the sample was divided into subgroups based on different regions for comparative analysis. Additionally, collinearity among the variables was examined. Results: The average hospitalization costs for the older adult are $1,199.24, with a burden score of 0.5. Residence, type of chronic diseases, region, family size, type of health service facility, received distance, smoke and alcoholic significantly affect the out-of-pocket expenses for older adult hospitalizations. In terms of the burden of hospitalization for the older adult, Residence, health insurance, education, type of chronic diseases, region, family size, ethnic, type of health service facility, received distance, smoke, alcoholic and pension significantly impact the hospitalization burden for the older adult. Conclusion: This paper provides a new perspective to explain the factors influencing hospitalizational costs and burden in China. The policy recommendations include expanding health insurance coverage and promoting commercial insurance to enhance the accessibility and financial security of healthcare services. Strengthening primary care is suggested to reduce the burden on hospitals and lower the overall cost of hospitalization. Policies aimed at addressing regional healthcare disparities are proposed, along with targeted support for vulnerable groups, including subsidies and culturally sensitive services.

Impact of health shocks on household consumption structure.

Introduction: In the aftermath of the pandemic, the impact of health shocks on household expenditure patterns has become a critical area of focus due to the heightened uncertainty surrounding consumers' expectations. Household medical expenditures have emerged as a key factor in the evolving consumption structure. Method: This research developed a practical framework to assess the influence of health shocks on family spending patterns, focusing on health shortfalls. Health emergencies were measured through randomized medical spending. Data was sourced from the 2010-2018 Wave 5 Statistical Report of the China Family Panel Studies (CFPS), which included a total of 25,809 participants. Results: The findings revealed that health shocks significantly increased the proportion of household spending on medical expenses. Concurrently, sub-expenditures such as food and education were reduced to varying degrees as households adjusted their consumption patterns to mitigate the impact of health shocks. The effects of these shocks were more pronounced in low-income households and those with health insurance. Discussions: The government should take steps to promote public health, reduce the burden of medical expenses resulting from health shocks, and unlock the consumption potential. Additionally, efforts should be made to boost economic growth and systematically upgrade household consumption patterns to effectively cushion the impact of health shocks.

Association of oral frailty with medical expenditure in older Japanese adults: The study of late-stage older adults in Tottori (START Tottori).

OBJECTS: This study aimed to determine the association between annual medical expenses and oral frailty in later-stage older adults (aged ≥ 75 years). No studies have investigated the association between medical costs and oral frailty, which would elucidate the association between oral frailty and the deterioration of mental and overall physical function. MATERIALS AND METHODS: In this cross-sectional study, 2190 adults (860 men and 1330 women aged 75-94 years) covered by the Medical System for the Elderly and residing in Tottori Prefecture, Japan, between April 2016 and March 2019, were included. Participants were classified into three groups: healthy, pre-orally frail or orally frail, based on dental health screening findings. The medical and dental expenses over the years, number of days of consultations and comorbidities were obtained from the Japanese Health Insurance Claims Database. RESULTS: The number of days of medical and dental consultations and annual medical expenses for outpatient care differed among the three study groups. A significant association was observed between oral frailty and high annual expenses for outpatient medical and dental care. Oral frailty was associated with higher medical expenses in participants with poor masticatory function. Higher and lower dental expenses were associated with subjective poor masticatory function and subjective impairment of swallowing function respectively. CONCLUSION: Medical and dental expenses for orally frail older adults are high, indicating that oral frailty may be related to the occurrence and severity of diseases other than oral health issues. Future studies should examine the mechanism by which oral weakness affects physical and mental functions.

The risk of free flap revision and subsequent medical costs in patients with hypopharyngeal cancer.

BACKGROUND: Few studies have examined the preoperative risks and healthcare costs related to free flap revision in hypopharyngeal cancer (HPC) patients. METHODS: A 20-year retrospective case-control study was conducted using the Chang Gung Research Database, focusing on HPC patients who underwent tumor excision and free flap reconstruction from January 1, 2001, to December 31, 2019. The impacts of clinical variables on the need for re-exploration due to free flap complications were assessed using logistic regression. The direct and indirect effects of these complications on medical costs were evaluated by causal mediation analysis. RESULTS: Among 348 patients studied, 43 (12.4%) developed complications requiring re-exploration. Lower preoperative albumin levels significantly increased the risk of complications (OR 2.45, 95% CI 1.12-5.35), especially in older and previously irradiated patients. Causal mediation analysis revealed that these complications explained 11.4% of the effect on increased hospitalization costs, after controlling for confounders. CONCLUSIONS: Lower preoperative albumin levels in HPC patients are associated with a higher risk of microvascular free flap complications and elevated healthcare costs, underscoring the need for enhanced nutritional support before surgery in this population.

The effect of outdoor activities on the medical expenditure of older people: multiple chain mediating effects of health benefits.

BACKGROUND: With the global aging population, attention to the health and medical issues of older adults is increasing. By analyzing the relationship between older people's participation in outdoor activities and medical expenditure, this study aims to provide a scientific basis for improving their quality of life and reducing the medical burden. METHODS: Data on outdoor activity participation, medical expenditures, and relevant variables were collected through questionnaires and databases. A multi-chain mediation effect model was established to analyze the impact of outdoor activities on the medical expenditure of older people, considering mediation effects and heterogeneity. RESULTS: Results revealed that increased participation in outdoor activities among older adults correlated with lower medical expenditures. Outdoor activities positively influenced their health by improving mental health, cognition, eating habits, and activities of daily living, resulting in reduced medical expenditures. Robustness tests confirmed the consistent effect of outdoor activities on older people's medical expenditure. CONCLUSION: These findings contribute to understanding the relationship between outdoor activities, health, and medical expenditure in older people, guiding policy formulation and interventions. Encouraging and supporting older adults in outdoor activities can enhance their quality of life and alleviate medical resource strain. The study's conclusions can also inform health promotion measures for other populations and serve as a basis for future research in this area.

Factors influencing medical expenditures in patients with unresolved facial palsy and pharmacoeconomic analysis of upper eyelid lid loading with gold and platinum weights compared to tarsorrhaphy.

There are no standards in diagnostic and therapeutic approaches to eye care in incomplete eyelid closure due to unresolved facial palsy (FP). Loading of the upper eyelid (UELL) with gold weights (GWs) or platinum chains (PCs) is a highly effective procedure for the correction of lagophthalmos. Despite this, the procedure is used infrequently in our country because of the relatively high price of the implant and the lack of reimbursement. The aim of this research was to assess the factors influencing medical expenditures in this group of patients and to analyze utility costs for the UELL procedure with the use of GW and PC compared to tarsorrhaphy.Material and methods The costs of 88 surgical procedures (40 GWs, 11 PCs and 37 tarsorrhaphies) and medical expenditures before and after surgery were calculated based on reporting of materials, staff salaries and the SF-36 questionnaire. Distribution quartiles of the cost per QALY measure (dependent variable) was assessed via an ordered logistic regression model with eight explanatory variables.Results The calculated total cost of the surgery was US$209 for tarsorrhaphy, US$758 for UELL with a GW and US$1,676 for UELL with a PC. Bootstrapped costs per QALY values (CUI) in 88% of cases were below the US$100,000 cutoff. Etiology and duration of facial palsy and presence of Bell's phenomenon were factors that significantly influenced the CUI. Patient gender and age, history of previous eyelid surgery, and presence of corneal sensation were found to be not significant (p > 0.1). Calculated ICER for GW was US$1,241.74/1QALY and ICER for PC was US$13,181.05/1QALY compared to tarsorrhaphy.Conclusions Eye protection in patients with FP should be a crucial element of health policy. Findings suggest UELL procedure with a GW or a PC to be a cost-effective procedure with GW being the most cost-effective.

Health care Utilization and Expenditures in Health Professional Shortage Areas.

Healthcare provider shortages are associated with adverse health outcomes, presumably stemming from the lack of access to primary care. This study examines the impact of Health Professional Shortage Areas (HPSAs) on healthcare utilization and spending across different types of care. Using the Medical Expenditure Panel Survey from 2002 to 2019, this study estimates the difference in healthcare utilization in HPSAs compared with non-HPSAs using a generalized random forest, which allows for more complex modeling of the outcome and a principled examination of heterogenous treatment effects. The results indicate HPSAs are associated with a 5% reduction in medical office visits, but no reduction in hospital-based care. These effects are concentrated in older persons living in urban areas, Black persons, and Medicaid beneficiaries. No statistically significant effects on annual spending were observed. These results offer insight into potential areas for further policy efforts aimed at reducing provider shortages.

The age-specific impact of COVID-19 vaccination on medical expenditures and hospitalization duration after breakthrough infection: The Vaccine Effectiveness, Networking, and Universal Safety (VENUS) Study.

OBJECTIVES: Although COVID-19 no longer constitutes a Public Health Emergency of International Concern, vaccination remains an important tool for reducing disease burden and mitigating future outbreaks. However, little is known about the impact of vaccination on medical expenditures and hospitalization duration after breakthrough infection. This study aimed to examine this impact during the Delta wave in Japan. METHODS: This retrospective study was conducted using medical care claims data, vaccination records, and COVID-19-related information. COVID-19 cases in three municipalities were categorized into two age groups: 20-64 years and ≥65 years. For each group, we constructed linear regression models with a generalized estimating equation. We calculated the risk ratios (RRs) and 95% confidence intervals (CIs) of COVID-19 vaccination for total medical expenditures and hospitalization duration after adjusting for sex, comorbidities, and municipality. RESULTS: We analyzed 618 cases aged 20-64 years (mean age: 38.4 years, women: 45.1%) and 208 cases aged ≥65 years (76.4 years, 53.8%). The RRs (95% CIs) of vaccination for total medical expenditures were 0.53 (0.44-0.64) in the 20-64 years age group and 0.51 (0.39-0.66) in the ≥65 years age group. Next, the RRs (95% CIs) of vaccination for hospitalization duration were 0.59 (0.42-0.83) in the 20-64 years age group and 0.69 (0.49-0.98) in the ≥65 years age group. CONCLUSIONS: COVID-19 vaccination was associated with lower total medical expenditures and hospitalization duration after breakthrough infection, with a more pronounced effect in older persons.

Patient Survey Regarding Non-Medical Burdens of Care at a Parental Fetal Care Center.

Recognizing the paucity of literature describing the non-medical effects of care at a tertiary parental fetal care center upon families, the purpose of the study was to better examine the potential barriers that our patients face related to care in a parental fetal care center. An anonymous survey was sent via email to patients who received care from 2015 to 2021. The survey included questions regarding demographics, fetal diagnoses, non-medical expenses related to care, and the impact of care on patient relationships, employment, and other children. 453 patients (15.9%) responded out of the 2684 emails sent. 58.3% of patients traveled >100 miles to reach our referral center, with 20% traveling >300 miles. 42.6% of patients reported non-medical expenditures exceeding $1000, with nearly 1 in 10 reporting expenditures of >$5000 (8.6%). Overall, 38.2% of women reported moderate to severe financial burdens related to receiving care at the parental fetal care center. This study illuminates the financial and social burdens that care at a tertiary parental fetal care center imposes upon families. By acknowledging these barriers, we can strive to minimize them to best provide equitable access to high-quality fetal care services.

Effects of the Implementation of Transport-Driven Poverty Alleviation Policy on Health Care-Seeking Behavior and Medical Expenditure Among Older People in Rural Areas: Quasi-Experimental Study.

BACKGROUND: Improving the rural residents' accessibility to and affordability of health care is recognized as a common target globally. The Health in All Policies approach, from the Declaration of Helsinki to the United Nations' Decade Of Healthy Ageing, strengthened the far-reaching effect of large-scale public policies on health care-seeking behavior; however, the effects of national transport policy on health care-seeking behavior is unclear. OBJECTIVE: This quasi-experimental study aimed to examine the effects of the implementation of transport-driven poverty alleviation (TPA) policy on health care-seeking behavior and medical expenditure among older adults in rural areas and the mechanism underlying these effects. METHODS: We designed a quasi-experiment to estimate the effects of TPA policy implementation on health care-seeking behavior and medical expenditure among older adults in rural areas through a difference-in-differences (DID) analysis based on data from the China Health and Retirement Longitudinal Study in 2011, 2013, 2015, and 2018. The underlying mechanism was analyzed and effect modification patterns were further investigated by poor households, health status, and age. RESULTS: Our findings validated a positive contribution of TPA policy on health care-seeking behavior among older adults in rural areas. After the implementation of TPA policy, the number of inpatient visits increased by annually 0.35 times per person, outpatient medical expenditure increased by 192% per month, and inpatient medical expenditure increased by 57% annually compared with those of older adults in rural areas without the implementation of TPA policy. Further, there was a significant modification effect, with a positive effect among poor households, healthier older adults, and those aged 60-80 years. Additionally, the policy improved the patients' capabilities to seek long-distance care (ß=23.16, 95% CI -0.99 to 45.31) and high-level hospitals (ß=.08, 95% CI -0.02 to 0.13), and increased individual income to acquire more medical services (ß=4.57, 95% CI -4.46 to 4.68). CONCLUSIONS: These findings validate the positive contribution of TPA policy on health care-seeking behavior among older adults in rural areas; however, the medical expenditure incurred was also high. Concerted efforts are needed to address health care-seeking dilemmas in rural areas, and attention must be paid to curbing medical expenditure growth for older adults in rural areas during TPA policy implementation.

Medications and medical expenditures for diabetic patients with osteoporosis in Beijing, China: A retrospective study.

AIMS: This study aimed to clarify the changes in treatment regimens and medical expenditures in diabetic patients with osteoporosis. METHODS: We recruited 2,853,036 diabetic patients from the Beijing medical insurance database between 2016 and 2018. Among them, 406,221 patients also had osteoporosis. Clinical characteristics, treatment regimens, and medical costs were investigated in diabetic patients with and without osteoporosis. RESULTS: Diabetes and osteoporosis were most prevalent in participants aged 45---84 years. Compared with diabetic patients without osteoporosis, those with osteoporosis were prone to developing comorbidities and diabetic complications. They often required multiple glucose-lowering drugs and had a higher rate of insulin use. Similarly, osteoporosis leads to an increased number of medications for non-hypoglycemia as well as higher healthcare costs. These medications and costs increased with the number of complications and comorbidities. Interestingly, from 2016 to 2018, although diabetic patients with osteoporosis took more drugs, medical costs were lower year by year. CONCLUSIONS: Osteoporosis might contribute to a worse condition in diabetic patients, and this population often requires more medications with higher medical costs.

The heterogeneous relationship between public health expenditures and household medical expenditures: evidence from relative poverty households in China.

Exploring the heterogeneous relationship between public health expenditures and household medical expenditures from the perspective of relative poverty has positive significance for improving the ability of relative poverty households to cope with the risk of large rigid expenditures and optimizing the public health resource allocation. This paper uses the China Family Panel Studies (CFPS) from 2016 to 2020 to identify relative poverty standard from the perspective of medical needs, analyzes the impact of public health expenditures on medical expenditures of different household types, and evaluates the effect of public health expenditures on ensuring the medical needs of relative poverty households. The panel threshold regression result shows that 19.36% of the provinces per capita disposable where the household is located is the identification standard of relative poverty households. Public health expenditures have a crowding-in effect on household medical expenditures and have a stronger impact on relative poverty households, an effect that is also confirmed by two-stage least squares regression. In addition, ensuring household medical needs through public health expenditures focuses on the level of basic medical needs, and the role of household healthcare expenditures that reflects high-level medical needs is not obvious. In the future, the government should establish a monitoring mechanism for relative poverty households, ensure the basic medical needs of relative poverty households, and clarify the heterogeneity among different types of households, provide targeted public health services.

Postacute Expenditures Among Patients Discharged Home After Stroke or Transient Ischemic Attack: The COMprehensive Post-Acute Stroke Services (COMPASS) Trial.

OBJECTIVES: The COMPASS (COMprehensive Post-Acute Stroke Services) pragmatic trial cluster-randomized 40 hospitals in North Carolina to the COMPASS transitional care (TC) postacute care intervention or usual care. We estimated the difference in healthcare expenditures postdischarge for patients enrolled in the COMPASS-TC model of care compared with usual care. METHODS: We linked data for patients with stroke or transient ischemic attack enrolled in the COMPASS trial with administrative claims from Medicare fee-for-service (n = 2262), Medicaid (n = 341), and a large private insurer (n = 234). The primary outcome was 90-day total expenditures, analyzed separately by payer. Secondary outcomes were total expenditures 30- and 365-days postdischarge and, among Medicare beneficiaries, expenditures by point of service. In addition to intent-to-treat analysis, we conducted a per-protocol analysis to compare Medicare patients who received the intervention with those who did not, using randomization status as an instrumental variable. RESULTS: We found no statistically significant difference in total 90-day postacute expenditures between intervention and usual care; the results were consistent across payers. Medicare beneficiaries enrolled in the COMPASS intervention arm had higher 90-day hospital readmission expenditures ($682, 95% CI $60-$1305), 30-day emergency department expenditures ($132, 95% CI $13-$252), and 30-day ambulatory care expenditures ($67, 95% CI $38-$96) compared with usual care. The per-protocol analysis did not yield a significant difference in 90-day postacute care expenditures for Medicare COMPASS patients. CONCLUSIONS: The COMPASS-TC model did not significantly change patients' total healthcare expenditures for up to 1 year postdischarge.

Rural pensions, intra-household bargaining, and elderly medical expenditure in China.

China's rural elderly spend less on medical expenditures as they age despite declining health, raising welfare concerns. This paper investigates the role of intrahousehold bargaining power on health expenditures of the elderly by evaluating the impact of cash transfers from a new social pension program. The program provided windfall payments to those above age 60, making it possible to employ a regression discontinuity design based on age of eligibility to estimate causal effects. Using data from the 2011 and 2013 waves of the China Health and Retirement Longitudinal Study, we find that receiving pension payments increases both the utilization of outpatient care and outpatient expenditures by the elderly who experienced illness. This result is robust to controlling for total household expenditures per capita, ruling out income effects as the main channel. Consistent with pensions increasing elderly bargaining power, we find that pensions significantly increase medical expenditures only for those elderly who co-reside with children or grandchildren but have no effect on those who live independently.

Is Fragmented Cancer Care Associated With Medical Expenditure? Nationwide Evidence From Patients With Lung Cancer Using National Insurance Claim Data.

Objectives: We aimed to investigate the association between fragmented cancer care in the early phase after cancer diagnosis and patient outcomes using national insurance claim data. Methods: We identified National Health Insurance beneficiaries diagnosed with lung cancer in South Korea from 2010 to 2014. We included 1,364 lung cancer patients with reduced immortal time bias and heterogeneity. We performed multiple regression analysis using a generalized estimate equation with a gamma distribution for medical expenditures. Results: Among the 1,364 patients with lung cancer, 12.8% had fragmented cancer care. Healthcare costs were higher in fragmented cancer care for both during diagnosis to 365 days and diagnosis to 1,825 days. Linear regression results showed that fragmented cancer care was associated with 1.162 times higher costs during the period from diagnosis to 365 days and 1.163 times the cost for the period from diagnosis to 1,825 days. Conclusion: We found fragmented cancer care is associated with higher medical expenditure. Future health policy should consider the limitation of patients' free will when opting for fragmented cancer care, as there are currently no control mechanisms.

Comparison of functional disabilities, place of death and end-of-life medical expenditures among centenarians and non-centenarians in China: a series of cross-sectional studies.

BACKGROUND: Long-term and end-of-life (EOL) care for older adults has become a global concern due to extended longevity, which is generally accompanied by increased rates of disability. However, differences in the rates of disability in activities of daily living (ADLs), place of death and medical expenditures during the last year of life between centenarians and non-centenarians in China remain unknown. This study aims to fill this research gap to inform policy efforts for the capacity-building of long-term and EOL care for the oldest-old, especially for centenarians in China. METHODS: Data from 20,228 decedents were derived from the 1998-2018 Chinese Longitudinal Healthy Longevity Survey. Weighted logistic and Tobit regression models were used to estimate differences in the prevalence of functional disability, rate of death in hospitals and EOL medical expenditures by age groups among oldest-old individuals. RESULTS: Of the 20,228 samples, 12,537 oldest-old individuals were female (weighted, 58.6%, hereafter); 3,767 were octogenarians, 8,260 were nonagenarians, and 8,201 were centenarians. After controlling for other covariates, nonagenarians and centenarians experienced a greater prevalence of full dependence (average marginal differences [95% CI]: 2.7% [0%, 5.3%]; 3.8% [0.3%, 7.9%]) and partial dependence (6.9% [3.4%, 10.3%]; 15.1% [10.5%, 19.8%]) but a smaller prevalence of partial independence (-8.9% [-11.6%, -6.2%]; -16.0% [-19.1%, -12.8%]) in ADLs than octogenarians. Nonagenarians and centenarians were less likely to die in hospitals (-3.0% [-4.7%, -1.2%]; -4.3% [-6.3%, -2.2%]). Additionally, nonagenarians and centenarians reported more medical expenditures during the last year of life than octogenarians with no statistically significant differences. CONCLUSION: The oldest-old experienced an increased prevalence of full and partial dependence in ADLs with increasing age and reported a decline in the prevalence of full independence. Compared with octogenarians, nonagenarians and centenarians were less likely to die in hospitals. Therefore, future policy efforts are warranted to optimise the service provision of long-term and EOL care by age patterns for the oldest-old population in China.

A Population-Based Study on Injury Risk and Disparities Among Children With ADHD.

OBJECTIVE: Impaired attention and inhibitory control put children with ADHD at potentially high risk of injury-one of the leading causes of disability in the general pediatric population. Existing research has yet to examine this important health risk using nationally representative samples. This population-based study aimed to address this gap. METHODS: National estimates of injury occurrences were generated from 66,236 children in the Medical Expenditures Panel Survey 2010-2019 datasets. Multiple logistic regression models further examined the impact of injury type, age, race/ethnicity, sex, parental education, income, marital and insurance status on injury prevalence. RESULTS: Compared to children without ADHD, those with ADHD have significantly higher injury prevalence (OR = 1.20, 95% CI [1.07, 1.33]) across injury types and most sociodemographic subgroups. CONCLUSIONS: Children with ADHD are more likely to experience injury. Future research should investigate mechanisms of injury disparities to inform future preventive efforts.

The relationship between subjective oral frailty and adverse health outcomes or medical and dental expenditures in the latter-stage older adult: A 6-year longitudinal study.

OBJECTIVES: The study aimed to investigate the relationship between subjective oral frailty and adverse health outcomes or medical and dental expenditures in the latter-stage older adult through a 6-year longitudinal study. METHODS: The participants enrolled in the cross-sectional study were 3564 Tokushima City residents aged 75, 80, 85, and 90 years old who received oral health examinations and who responded to a questionnaire on oral conditions and health behavior at baseline. The data for the occurrence of disability or mortality, and the monthly medical expenditures, dental expenditures, and total medical expenditure of each participant were obtained from the National Health Insurance Database. RESULTS: The total medical expenditure showed significant differences in participants who had difficulties in eating tough foods, difficulties in swallowing tea or soup, and dry mouth when compared to that of healthy participants, in addition to the current medical treatment against the general disease. The 6-year longitudinal study revealed that participants with subjective oral frailty symptoms, including difficulties in eating tough foods and difficulties in swallowing tea or soup at baseline, had significantly higher medical, dental, and total expenditures among 538 participants without certified nursing care. In addition, those with subjective oral frailty or with less than 19 teeth present were shown to have a higher possibility for the occurrence of disability or mortality by the cox proportional hazard analysis. Furthermore, it was found that medical and total expenditures in older adults with adverse health outcomes were higher than that of healthy participants. CONCLUSION: These results suggest that subjective oral frailty in the latter-stage older adult is related to subsequent adverse health outcomes and an increase in medical and dental expenditures.

Medical Expenditures Associated with Attention-Deficit/Hyperactivity Disorder Among Adults in the United States by Age, 2015-2019.

BACKGROUND: Attention-deficit hyperactivity disorder is a common disorder that affects both children and adults. However, for adults, little is known about ADHD-attributable medical expenditures. OBJECTIVE: To estimate the medical expenditures associated with ADHD, stratified by age, in the US adult population. DESIGN: Using a two-part model, we analyzed data from Medical Expenditure Panel Survey for 2015 to 2019. The first part of the model predicts the probability that individuals incurred any medical costs during the calendar year using a logit model. The second part of the model estimates the medical expenditures for individuals who incurred any medical expenses in the calendar year using a generalized linear model. Covariates included age, sex, race/ethnicity, geographic region, Charlson comorbidity index, insurance, asthma, anxiety, and mood disorders. PARTICIPANTS: Adults (18 +) who participated in the Medical Expenditure Panel Survey from 2015 to 2019 (N = 83,776). MAIN MEASURES: Overall and service specific direct ADHD-attributable medical expenditures. KEY RESULTS: A total of 1206 participants (1.44%) were classified as having ADHD. The estimated incremental costs of ADHD in adults were $2591.06 per person, amounting to $8.29 billion nationally. Significant adjusted incremental costs were prescription medication ($1347.06; 95% CI: $990.69-$1625.93), which accounted for the largest portion of total costs, and office-based visits ($724.86; 95% CI: $177.75-$1528.62). The adjusted incremental costs for outpatient visits, inpatient visits, emergency room visits, and home health visits were not significantly different. Among older adults (31 +), the incremental cost of ADHD was $2623.48, while in young adults (18-30), the incremental cost was $1856.66. CONCLUSIONS: The average medical expenditures for adults with ADHD in the US were substantially higher than those without ADHD and the incremental costs were higher in older adults (31 +) than younger adults (18-30). Future research is needed to understand the increasing trend in ADHD attributable cost.

Disparities in the medical expenditures of patients with cancer and concomitant mental disorder: analyzing the effects of diagnosis sequence order.

BACKGROUND: Cancer is the leading cause of death in Taiwan. Medical expenditures related to cancer accounted for 44.8% of all major illness insurance claims in Taiwan. Prior research has indicated that the dual presence of cancer and mental disorder in patients led to increased medical burden. Furthermore, patients with cancer and concomitant mental disorder could incur as much as 50% more annual costs than those without. Although previous studies have investigated the utilization of patients with both diseases, the effects of morbidity sequence order on patient costs are, however, uncertain. This study explored medical expenditures linked with the comorbidity of cancer and mental disorder, with a focus on the impact of diagnosis sequence order. METHODS: This population-based retrospective matched cohort study retrieved patients with cancer and mental disorder (aged ≥ 20 years) from the Ministry of Health and Welfare Data Science Center 2005-2015 database. 321,045 patients were divided based on having one or both diseases, as well as on the sequence of mental disorder and cancer diagnosis. Study subjects were paired with comparison counterparts free of both diseases using Propensity Score Matching at a 1:1 ratio. Annual Cost per Patient Linear Model (with a log-link function and gamma distribution) was used to assess the average annual cost, covarying for socio-demographic and clinical factors. Binomial Logistic Regression was used to evaluate factors associated with the risk of high-utilization. RESULTS: The "Cancer only" group had higher adjusted mean annual costs (NT$126,198), more than 5-times that of the reference group (e^ß: 5.45, p < 0.001). However, after exclusion of patients with non-cancer and inclusion of diagnosis sequence order for patients with cancer and concomitant mental disorder, the post-cancer mental disorder group had the highest expenditures at over 13% higher than those diagnosed with only cancer on per capita basis (e^ß: 1.13, p < 0.001), whereas patients with cancer and any pre-existing mental disorder incurred lower expenditures than those with only cancer. The diagnosis of post-cancer mental disorder was significantly associated with high-utilization (OR = 1.24; 95% CI: 1.047-1.469). Other covariates associated with high-utilizer status included female sex, middle to old age, and late stage cancer. CONCLUSION: Presence of mental disorder prior to cancer had a diminishing effect on medical utilization in patients, possibly indicating low medical compliance or adherence in patients with mental disorder on initial treatments after cancer diagnosis. Patients with post-cancer mental disorder had the highest average annual cost. Similar results were found in the odds of reaching high-utilizer status. The follow-up of cancer treatment for patients with pre-existing mental disorders warrants more emphasis in an attempt to effectively allocate medical resources.
