Medicare expenditures among spouses of persons with dementia.

BACKGROUND: Spouses of persons living with dementia face intense strains on their well-being compared with similarly aged adults and spouses of partners with no dementia. This strain can impact spouses' health and healthcare needs, and therefore affect their healthcare utilization and expenditures. METHODS: Using data from the Health and Retirement Study linked with Medicare claims, we matched dyads of spouses and their partners with dementia (SPWD) to a comparison group of similar spouses and their partners with no dementia (SPWND). We then examined Medicare expenditures for spouses in the 5 years following their partner's dementia onset month using a two-part regression model. RESULTS: SPWD cumulative total Medicare expenditures were, on average, $60,043 in the 5 years post dementia onset, compared to $56,068 for SPWND. This difference ($3974, 95% CI = [-$3,199; $11,477]) was not significant. However, there were significant differences in the 5th year's total expenditures (+$2,748 [$321; $5,447]), driven by inpatient expenditures ($1,562 [$22; $3,277]). CONCLUSIONS: Despite the differences in partner's dementia status, we found no significant difference in the 5-year cumulative Medicare expenditures between SPWD and SPWND. Compared to previous studies, we likely captured an earlier stage of dementia more consistently for a broader population which may be less straining on spouses. Further research should examine patterns of expenditures in later years and around critical timepoints in caregiving, such as partner transitions to formal long-term care settings and death, to better understand healthcare expenditures for spouses of persons living with dementia.

Association between the nutritional quality of food purchases and household food at home expenditures in Mexico.

BACKGROUND: Poor-quality diets are a major risk factor for non-communicable diseases. Few studies in Mexico have tested whether higher expenditures are needed to purchase high quality food. OBJECTIVE: The objective of the study was to assess how dietary quality for food purchases was associated with household food at home expenditures. DESIGN: This study is a secondary analysis of cross-sectional data from the National Household Income and Expenditure Survey (ENIGH 2018). PARTICIPANTS/SETTING: The study includes 74,469 households with information on food and beverages purchases in Mexico in 2018. MAIN OUTCOME MEASURES: Quarterly household food expenditures by adult equivalent (AE) for all food groups that were scored in the Global Dietary Quality Score (GDQS) for food purchases expressed in dollars/quarterly/AE. STATISTICAL ANALYSES PERFORMED: Adjusted generalized linear models were used to evaluate the association between GDQS for food purchases (expressed in tertiles: low-, mid-, and high-), and quarterly food expenditures. The analyses were performed at the national level, by place of residence and income quintile. RESULTS: At the national level, the difference in food expenditures between the high- and the low-GDQS group was +$13.85 dollars/AE. By place of residence, the difference between the high- and the low-GDQS group was +$17.31 dollars/AE in urban and +$5.12 dollars/AE in rural areas. For income quintile 1 (lowest) there was statistical difference of -$4.79 dollars/AE and for quintile 5 (highest) +$43.25. CONCLUSIONS: Quality of food purchases can be associated with higher or lower expenditures depending on the specific food purchased. High GDQS is associated with lower expenditures among the lowest-income households as they purchase less expensive options compared to high-income households.

The Association between Short-Term Exposure to PM1 and Daily Hospital Admission and Related Expenditures in Beijing.

Ambient particulate matter (PM) pollution is a leading environmental health threat worldwide. PM with an aerodynamic diameter ≤ 1.0 µm, also known as PM1, has been implicated in the morbidity and mortality of several cardiorespiratory and cerebrovascular diseases. However, previous studies have mostly focused on analyzing fine PM (PM2.5) associated with disease metrics, such as emergency department visits and mortality, rather than ultrafine PM, including PM1. This study aimed to evaluate the association between short-term PM1 exposure and hospital admissions (HAs) for all-cause diseases, chronic obstructive pulmonary disease (COPD), and respiratory infections (RIs), as well as the associated expenditures, using Beijing as a case study. Here, based on air pollution and hospital admission data in Beijing from 2015 to 2017, we performed a time-series analysis and meta-analysis. It was found that a 10 µg/m3 increase in the PM1 concentration significantly increased all-cause disease HAs by 0.07% (95% Confidence Interval (CI): [0, 0.14%]) in Beijing between 2015 and 2017, while the COPD and RI-related HAs were not significantly associated with short-term PM1 exposure. Meanwhile, we estimated the attributable number of HAs and hospital expenditures related to all-cause diseases. This study revealed that an average of 6644 (95% CI: [351, 12,917]) cases of HAs were attributable to ambient PM1, which was estimated to be associated with a 106 million CNY increase in hospital expenditure annually (95% CI: [5.6, 207]), accounting for 0.32% (95% CI: [0.02, 0.62%]) of the annual total expenses. The findings reported here highlight the underlying impact of ambient PM pollution on health risks and economic burden to society and indicate the need for further policy actions on public health.

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.

[Main characteristics and historical evolution of China' s health financing transition].

OBJECTIVE: To comprehend the main characteristics and historical evolution of health financing transition in China. METHODS: Data were collected from various sources, including the Global Health Expenditure Database (GHED), China Health Statistics Yearbook, National Health Finance Annual Report, China ' s Total Health Expenditure Research Report, et al. Descriptive statistics and literature study was conducted. RESULTS: Since the beginning of the 21st century, most countries in the world had witnessed a transition of health financing, characterized by the expansion of health financing scale and the strengthening of public financing responsibility. Notably, China ' s health financing transition exhibited distinctive features. Firstly, there had been a more rapid expansion in health financing scale compared with global averages. Between 2000 and 2019, total health expenditure per capita experienced a remarkable increase of 816.6% at comparable prices, significantly surpassing average growth rates observed among other countries worldwide (102.1%). Secondly, greater efforts had been made to strengthen the responsibilities of public financing. From 2000 to 2019, there was a substantial decrease of 30.6 percentage points in the proportion of out-of-pocket health expenditure as a share of total health expenditure. This decline was significantly larger than the average reduction observed among other countries worldwide (5.6 percentage points). Thirdly, there had been a significant shift in government health expenditure allocation patterns, with an increased emphasis on "demand-side subsidies" surpassing "supply-side subsidies". Within the realm of "supply-side subsidies", funding directed towards hospitals had notably increased and surpassed that allocated to primary healthcare institutions and public health institutions. Based on these distinctive characteristics, this paper expanded China ' s health financing transition into three dimensions: Scale dimension, structure dimension and flow dimension. Using a comprehensive analytical framework, the history of China ' s health financing transition was roughly divided into four stages: The planned economy stage, the economic transition stage, the post-SARS stage and the new health system reform stage. The main features and evolutionary logic associated with each stage were analyzed. CONCLUSION: Above all, the health financing system should be enhanced in terms of vertical "embeddedness" and horizontal "complementarity". Moreover, the significance of health financing transition in preserving hidden value and mitigating public risk should be emphasized, and there is a need for an improved two-way trade-off mechanism that balances value and risk. Additionally, the ethical principles associated with health financing transition should be considered comprehensively, while optimizing budget decision-making within the government ' s actual governance model. Lastly, it is crucial to recognize the overall and profound impact of modern medicine development and explore long-term strategies and pathways for health financing transition in China.

The impact of the expanded health insurance coverage policy on healthcare spending: evidence from Korea.

BACKGROUND: South Korea's National Health Insurance (NHI) system pursues universal health coverage, but it has not been able to alleviate patients' financial burden owing to limited coverage and a high proportion of out-of-pocket expenses. In 2017, the government announced a plan to strengthen universality by providing coverage for all unincluded services, expanding coverage, and alleviating household financial burden. We aimed to evaluate the effect of "Moon Care" with a focus on changes in health expenditures following policy implementation, and to provide empirical evidence for future policies to strengthen the NHI system's universality. METHODS: Using data from the 2016 and 2018 Korea Health Panel (KHP), we established a treatment group affected by the policy and an unaffected control group; we ensured homogeneity between the groups using propensity score matching (PSM). Subsequently, we examined changes in NHI payments, non-payments, and out-of-pocket payments (OOP); we performed difference-in-differences (DID) analysis to evaluate the policy's effect. RESULTS: Following policy implementation, the control group had a higher increase than the treatment group in all categories of health expenditures, including NHI payments, non-payments, and OOP. We noted significant decreases in all three categories of health expenditures when comparing the differences before and after policy implementation, as well as between the treatment and control groups. However, we witnessed a significant decrease in the interaction term, which confirms the policy's effect, but only for non-payments. CONCLUSIONS: We observed the policy's intervention effect over time as a decrease in non-payments, on the effectivity of remunerating covered medical services. However, the policy did not work for NHI payments and OOP, suggesting that it failed to control the creation of new non-covered services as noncovered services were converted into covered ones. Thus, it is crucial to discuss the financial spending of health insurance regarding the inclusion of non-covered services in the NHI benefits package.

Comparative Interrupted Time Series Analysis of Medical Expenses in Patients with Intertrochanteric Fracture Who Underwent Internal Fixation and Hemiarthroplasty.

Purpose: The objective of this study was to assess postoperative direct medical expenses and medical utilization of elderly patients who underwent either hemiarthroplasty (HA) or internal fixation (IF) for treatment of a femoral intertrochanteric fracture and to analyze differences according to surgical methods and age groups. Materials and Methods: Data from the 2011 to 2018 Korean National Health Insurance Review & Assessment Service database were used. Risk-set matching was performed for selection of controls representing patients with the same sex, age, and year of surgery. A comparative interrupted time series analysis was performed for evaluation of differences in medical expenses and utilization between the two groups. Results: A total of 10,405 patients who underwent IF surgery and 10,405 control patients who underwent HA surgery were included. Medical expenses were 18% lower in the IF group compared to the HA group during the first year after the fracture (difference-in-difference [DID] estimate ratio 0.82, 95% confidence interval [CI] 0.77-0.87, P<0.001), and 9% lower in the second year (DID estimate ratio 0.91, 95% CI 0.85-0.99, P=0.018). Length of hospital stay was significantly shorter in the IF group compared to the HA group during the first two years after time zero in the age ≥80 group. Conclusion: A noticeable increase in medical expenses was observed for patients who underwent HA for treatment of intertrochanteric fractures compared to those who underwent IF over a two-year period after surgery. Therefore, consideration of such findings is critical when designing healthcare policy support for management of intertrochanteric fractures.

Association of surgeon's sex, and surgeon-patient dyad with financial outcomes among patients undergoing cancer surgery.

BACKGROUND AND OBJECTIVES: Surgeon sex has been associated with perioperative clinical outcomes among patients undergoing oncologic surgery. There may be variations in financial outcomes relative to the surgeon-patient dyad. We sought to define the association of surgeon's sex with perioperative financial outcomes following cancer surgery. METHODS: Patients who underwent resection of lung, breast, hepato-pancreato-biliary (HPB), or colorectal cancer between 2014 and 2021 were identified from the Medicare Standard Analytic Files. A generalized linear model with gamma regression was utilized to characterize the association between sex concordance and expenditures. RESULTS: Among 207,935 Medicare beneficiaries (breast: n = 14,753, 7.1%, lung: n = 59,644, 28.7%, HPB: n = 23,400, 11.3%, colorectal: n = 110,118, 53.0%), 87.8% (n = 182,643) and 12.2% (n = 25,292) of patients were treated by male and female surgeons, respectively. On multivariable analysis, female surgeon sex was associated with slightly reduced index expenditures (mean difference -$353, 95%CI -$580, -$126; p = 0.003). However, there were no differences in 90-day post-discharge inpatient (mean difference -$-225, 95%CI -$570, -$121; p = 0.205) and total expenditures (mean difference $133, 95%CI -$279, $545; p = 0.525). CONCLUSIONS: There was minor risk-adjusted variation in perioperative expenditures relative to surgeon sex. To improve perioperative financial outcomes, a diverse surgical workforce with respect to patient and surgeon sex is warranted.

Financial Toxicity in Relation to Childbirth.

OBJECTIVE: To measure change in financial toxicity from pregnancy to the postpartum period and to identify factors associated with this change. DESIGN: Repeated cross-sectional survey. SETTING: Obstetric clinics at an academic medical center in Massachusetts between May 2020 and May 2022. PARTICIPANTS: Obstetric patients who were 18 years of age or older (N = 242). METHODS: Respondents completed surveys that included the Comprehensive Score for Financial Toxicity tool during pregnancy and in the postpartum period. We collected additional medical record data, including gestational age, birth weight, and cesarean birth. We used paired t tests to assess changes in financial toxicity before and after childbirth and one-way analysis of variance to compare average change in financial toxicity by demographic and medical variables. RESULTS: The mean current financial toxicity score was significantly lower after childbirth (M = 19.0, SD = 4.6) than during pregnancy (M = 21.8, SD = 5.4), t(241) = 13.31, p < .001. Concern for future financial toxicity was not significantly different after childbirth (M = 8.5, SD = 2.9) compared to during pregnancy (M = 8.2, SD = 3.0), t(241) = -1.80, p = .07. Individual-level sociodemographic variables (e.g., racial/ethnic category, insurance, employment) and medical factors (e.g., cesarean birth, preterm birth) were not associated with change in financial toxicity. CONCLUSION: Among respondents, financial toxicity worsened after childbirth, and patients are at risk regardless of their individual socioeconomic and medical conditions.

Economic burden and dosing trends of buprenorphine buccal film and transdermal patch in chronic low back pain.

Aim: Exploring prescribing trends and economic burden of chronic low back pain (cLBP) patients prescribed buprenorphine buccal film (Belbuca®) or transdermal patches. Methods: In the MarketScan® commercial insurance claims (employees and their spouses/dependents, 2018-2021), the first film or patch prescription date was an index event. The observation covered 6-month pre-index and 12-month post-index periods. Results: Patients were propensity-score matched (708 per cohort). Buprenorphine initiation had stable cost trends in buccal film and increasing trends in transdermal patch cohort. Between-cohort comparisons of healthcare expenditures, cost trends and resource utilization showed significant differences, mostly in favor of buccal film. Buccal film also had higher daily doses and wider dosing range. Conclusion: Buprenorphine film is more cost-effective cLBP treatment with more flexible dosing.

What is this article about? This retrospective study included patients with chronic low back pain (cLBP) and commercial insurance in the USA. Only patients treated with Belbuca®, a buprenorphine buccal film, or a buprenorphine transdermal patch were included. Patients were observed 6 months prior to and 12 months after the first buprenorphine prescription. Healthcare costs, cost trends, resource use and buprenorphine treatment characteristics were explored.What were the results? Patients with cLBP on buccal film had lower costs, stable cost trends and less healthcare resources used. Also, they had higher buprenorphine daily doses.What do the results mean? The results imply that buccal film is less costly for cLBP patients than patches. The buccal film had more flexible dosing with higher daily doses, which might be associated with better pain control.

Eco-friendly revenues for healthcare: assessing the relationship between green taxation, public health expenditures, and life expectancy in China.

Introduction: The synergy of green taxation, public health expenditures, and life expectancy emerges as a compelling narrative in the intricate symphony of environmental responsibility and public well-being. Therefore, this study examine the impact of green taxation on life expectancy and the moderating role of public health expenditure on the said nexus, particularly in the context of China, an emerging economy. Methods: Statistical data is collected from the National Bureau of Statistics of China to empirically examine the proposed relationships. The dataset contains provincial data across years. Results: Using fixed-effect and system GMM regression models alongwith control variables, the results found a positive and statistically significant influence of green taxation on life expectancy. Moreover, public health expenditures have a positive and statistically significant partial moderating impact on the direct relationship. Discussion: These findings suggest that the higher cost of pollution encourages individuals and businesses to shift to less environmentally harmful alternatives, subsequently improving public health. Moreover, government investment in the health sector increases the availability and accessibility of health facilities; thus, the positive impact of green taxation on public health gets more pronounced. The findings significantly contribute to the fields of environmental and health economics and provide a new avenue of research for the academic community and policymakers.

Household Environments and Cognitive Decline Among Middle-Aged and Older Adults in China: Exploring Gender, Age, and Residential Variations.

This study examined the relationship between household environments and trajectories of cognitive function among middle-aged and older adults in China and its urban/rural, gender, and age variations. We estimated multi-level linear growth curve models using a representative sample of 16,111 respondents aged 45 years and over from the China Health and Retirement Longitudinal Study (2011-2018). Older people who lived with a spouse, but not with children, and those with higher living expenditures, better housing quality, and indoor clean fuels for cooking had a slower cognitive decline. Living arrangement more strongly predicted men's cognitive decline, while living expenditure, solid fuel use, and housing quality significantly predicted only women's cognitive decline. Only for older adults and rural residents, those living alone had significantly faster cognitive decline than those living with a spouse only. These findings underscore the importance of improving the living conditions of older adults to help alleviate their cognitive decline.

Modelling impacts of a salt and sugar tax on hypothetical intra-category food substitutions, BMI and environmental footprints in the UK population.

PURPOSE: Taxes on unhealthy foods can help improve population health in the United Kingdom (UK), but the health effects of food substitutions resulting from these taxes are often unclear. We investigated the potential impacts of a salt and sugar tax on hypothetical intra-category food substitutions, cost, body-mass index (BMI), and environmental footprints. METHODS: Purchase panel data from Kantar (2017) were used to determine the most popular foods high in salt or sugar within eight 'salt-intensive'/'sugar-intensive' food categories. Within food categories, the most popular lower salt (≤ 1.5 g salt/100 g product) and lower sugar (≤ 22.5 g sugar/100 g product) substitutes were also identified. Hypothetical swaps between high salt/sugar foods and lower salt/sugar substitutes were explored, focusing on changes to cost, caloric intake and BMI, and environmental impacts in the UK population. RESULTS: The suggested intra-category substitutions were largely like-for-like and did not accrue an added overall cost to consumers. The substitutions reduced calorie intake by about 200 kcal/day and lowered the prevalence of overweight and obesity in the UK from approximately 60-65% to about 40-45%. The proposed food substitutions led to a total reduction of -2.7Mt of greenhouse gases, ∼ -500.000 ha of land, -0.5km3 of blue water, -12km3 of scarcity weighted water, ∼ -12.000t of phosphorus, and nearly - 14.000t of sulphur dioxide over one year for the UK population due to reductions in calorie intake. CONCLUSION: Food substitutions following a tax on salt and sugar could lead to significant benefits for health and the environment, without necessarily resulting in major changes to people's expenditure on familiar salty and sugary snacks.

Characteristics and spending patterns of high-cost child patients: findings from Fujian in China.

BACKGROUND: The health condition during childhood has been shown to influence an individual's health and socioeconomic status in adulthood. Understanding the concentration and persistence patterns in children's healthcare expenditures is crucial for providing risk protection and promoting the well-being of children. Studies regarding the concentration and persistence of health expenditures have focused mainly on elderly individuals in developed regions. To gain insights into factors that contribute to childhood health expenditures, this article examined children with high costs (that is, in the top 10% of the expenditure distribution) and explored the characteristics and spending patterns that distinguished them from other patients in the context of the largest developing economy-China. METHODS: By using a unique individual-level administrative claims dataset over a 5-year observation period, this study identified spending concentrations and the proportion of children whose costs remained high over five years using a linear probability model and logit regression analysis. RESULTS: Teenagers from 12 to 17 years old were more likely to persist in the high-cost group than any other age groups in the study. Pediatric complex chronic conditions and other severe health ailments were predictive factors for entry into and persistence in the high-cost category. More than half of the total health expenditures were attributed to children in the top 10% expenditure group. In addition, risk protection and healthcare insurance support for high-cost children was found to be inadequate, particularly for children from low-income families. CONCLUSIONS: Healthcare support for children impacts individual development and family financial status. This study described the characteristics and spending patterns of children patients in the largest developing country. The fact that over half of total expenditures are concentrated toward 10% of patients makes it valuable to consider relevant support for this group, especially for families whose medical costs are higher than income.

Measurements of Impoverishing and Catastrophic Surgical Health Expenditures in Low- and Middle-Income Countries and Reduction Interventions in the Last 30 Years: A Systematic Review.

INTRODUCTION: Approximately 33 million people suffer catastrophic health expenditure (CHE) from surgery and/or anesthesia costs. The aim of this systematic review is to evaluate catastrophic and impoverishing expenditure associated with surgery and anesthesia in low- and middle-income countries (LMICs). METHODS: We performed a systematic review of all studies from 1990 to 2021 that reported CHE in LMICs for treatment of a condition requiring surgical intervention, including cesarean section, trauma care, and other surgery. RESULTS: 77 studies met inclusion criteria. Tertiary facilities (23.4%) were the most frequently studied facility type. Only 11.7% of studies were conducted in exclusively rural health-care settings. Almost 60% of studies were retrospective in nature. The cost of procedures ranged widely, from $26 USD for a cesarean section in Mauritania in 2020 to $74,420 for a pancreaticoduodenectomy in India in 2018. GDP per capita had a narrower range from $315 USD in Malawi in 2019 to $9955 USD in Malaysia in 2015 (Median = $1605.50, interquartile range = $1208.74). 35 studies discussed interventions to reduce cost and catastrophic expenditure. Four of those studies stated that their intervention was not successful, 18 had an unknown or equivocal effect on cost and CHE, and 13 concluded that their intervention did help reduce cost and CHE. CONCLUSIONS: CHE from surgery is a worldwide problem that most acutely affects vulnerable patients in LMICs. Existing efforts are insufficient to meet the true need for affordable surgical care unless assistance for ancillary costs is given to patients and families most at risk from CHE.

Healthcare utilization and expenditures among patients with venous thromboembolism following gastrointestinal cancer surgery.

BACKGROUND: We sought to assess healthcare utilization and expenditures among patients who developed venous thromboembolism (VTE) after gastrointestinal cancer surgery. METHODS: Patients who underwent surgery for esophageal, gastric, hepatic, biliary duct, pancreatic, and colorectal cancer between 2013 and 2020 were identified using the MarketScan database. Entropy balancing was performed to obtain a cohort that was well balanced relative to different clinical covariates. Generalized linear models were used to compare 1-year postdischarge costs among patients who did and did not develop a postoperative VTE. RESULTS: Among 20,253 individuals in the analytical cohort (esophagus [n = 518 {2.6%}], stomach [n = 970 {4.8%}], liver [n = 608 {3.0%}], bile duct [n = 294 {1.5%}], pancreas [n = 1511 {7.5%}], colon [n = 12,222 {60.3%}], and rectum [n = 4130 {20.4%}]), 894 (4.4%) developed VTE. Overall, most patients were male (n = 10,656 [52.6%]), aged between 55 and 64 years (n = 10,372 [51.2%]), and were employed full time (n = 11,408 [56.3%]). On multivariable analysis, VTE was associated with higher inpatient (mean difference [MD], $17,547; 95% CI, $15,141-$19,952), outpatient (MD, $8769; 95% CI, $7045-$10,491), and pharmacy (MD, $2811; 95% CI, $2509-$3113) expenditures (all P < .001). Furthermore, patients who developed VTE had higher out-of-pocket costs for inpatient (MD, $159; 95% CI, $66-$253) and pharmacy (MD, $122; 95% CI, $109-$136) services (all P < .001). CONCLUSION: Among privately insured patients aged <65 years, VTE was associated with increased healthcare utilization and expenditures during the first year after discharge.

Advance Care Planning (ACP) in Medicare Beneficiaries with Heart Failure.

BACKGROUND: Heart failure is a leading cause of death in the USA, contributing to high expenditures near the end of life. Evidence remains lacking on whether billed advance care planning changes patterns of end-of-life healthcare utilization among patients with heart failure. Large-scale claims evaluation assessing billed advance care planning and end-of-life hospitalizations among patients with heart failure can fill evidence gaps to inform health policy and clinical practice. OBJECTIVE: Assess the association between billed advance care planning delivered and Medicare beneficiaries with heart failure upon the type and quantity of healthcare utilization in the last 30 days of life. DESIGN: This retrospective cross-sectional cohort study used Medicare fee-for-service claims from 2016 to 2020. PARTICIPANTS: A total of 48,466 deceased patients diagnosed with heart failure on Medicare. MAIN MEASURES: Billed advance care planning services between the last 12 months and last 30 days of life will serve as the exposure. The outcomes are end-of-life healthcare utilization and total expenditure in inpatient, outpatient, hospice, skilled nursing facility, and home healthcare services. KEY RESULTS: In the final cohort of 48,466 patients (median [IQR] age, 83 [76-89] years; 24,838 [51.2%] women; median [IQR] Charlson Comorbidity Index score, 4 [2-5]), 4406 patients had an advance care planning encounter. Total end-of-life expenditure among patients with billed advance care planning encounters was 19% lower (95% CI, 0.77-0.84) compared to patients without. Patients with billed advance care planning encounters had 2.65 times higher odds (95% CI, 2.47-2.83) of end-of-life outpatient utilization with a 33% higher expected total outpatient expenditure (95% CI, 1.24-1.42) compared with patients without a billed advance care planning encounter. CONCLUSIONS: Billed advance care planning delivery to individuals with heart failure occurs infrequently. Prioritizing billed advance care planning delivery to these individuals may reduce total end-of-life expenditures and end-of-life inpatient expenditures through promoting use of outpatient end-of-life services, including home healthcare and hospice.

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.
