Healthcare Resource Utilization, Costs, Clinical Events, and Treatment Patterns in Extreme High-Risk Patients for Cardiovascular Events Undergoing Lipoprotein Apheresis: A German Claims Data Analysis

Abstract Aim Insights into treatment patterns, clinical and economic burden of patients undergoing Lipoprotein apheresis (LA). 3 cohorts were characterized: newly treated [Cohort A], experienced [B], matched cohort [C, high CV risk without LA]. Method Clinical burden was assessed by cardiovascular-related hospitalizations and procedures. Economic and clinical outcomes were described over a 12-month baseline period up to 3 years after LA initiation. Results Absolute LA cases decreased from 1.7 to 1.1 per 100,000 patients. In Cohort A, rate of major cardiovascular hospitalizations decreased, while annual healthcare expenditure increased. Cohort B had significantly higher costs than C. Conclusion LA may be associated with a reduced frequency of myocardial infarction-related hospitalizations. However, it is expensive. Alternatives are needed to reduce its high economic burden.

Health Security of Unorganised Construction Workers Through Ayushman Bharat (PM-JAY) Special reference to the Haldwani Development Block

Purpose of the study – This study explores the Ayushman Bharat Scheme (PM-JAY) in the Haldwani Development Block of Uttarakhand, focusing on awareness, utilization, and impact among unorganized construction workers. It also assesses the scheme's accessibility in rural and urban areas within the study area. Design/methodology/approach – The present study is based on descriptive and analytical research design. The cross-sectional study was conducted within the rural and urban parts of the study area. The study is based on primary data and the data was collected through a close-ended interview schedule with the sample size of N = 384, which is determined through William Cochran’s methods for infinite population size. Statistical tool – Descriptive statistics has been used for summarizing the result of the study and in the inferential statistics Spearmen’s rank correlation, Chi-Square, one sample t-test and Likert Scale Analysis have been used. Conclusion - The study reveals that in the case of awareness, the schemes were successful but there is substantial gaps exist in the utilization of Ayushman Bharat Schemes (PM-JAY) among the unorganised construction workers. The researcher found a weak negative correlation coefficient between the level of education and awareness, enrollment and availing the benefits of the Ayushman Bharat schemes. Rural respondents have received more benefits than urban respondents. Enrolment in Ayushman Bharat leads to significant reductions in annual healthcare expenditure. This suggests that PM-JAY helps reduce out-of-pocket healthcare costs, making medical services more affordable to unorganised construction workers. On average, respondents reported a moderately positive perception regarding the shift of their healthcare utilization from informal to formal channels due to PM-JAY.

Air, land, and water pollutants and public health expenditures: Empirical data from selected EU countries in the transport sector

The increase in economic activity, particularly in transport, leads to a significant increase in emissions of pollutants, such as ammonia, arsenic and cadmium, at the European Union (EU) level. This can seriously impact human health and, consequently, public health spending. Based on data from 15 European Union countries from 1992 to 2020, a panel co-integration approach is used to study these pollutants’ short- and long-term co-movements and per capita health expenditure. The results show a long-term relationship between ammonia, arsenic and cadmium emissions and per capita health spending, as they are panel-cointegrated. Ammonia and cadmium emissions exert a statistically significant positive effect on health expenditure in the short run, and arsenic emissions have a statistically significant positive impact in the long run. The forecast assessment of reductions in health spending resulting from policies to reduce emissions of air, land and water pollutants, such as ammonia, arsenic and cadmium, from the transport sector supports investments in its policies that reduce pressure on health spending. The reduction in annual healthcare expenditure is greater when these reductions are made sooner and more severely. Indeed, varying the reduction in emissions for each pollutant by 10% and 100%, respectively, from the first year for all countries over a 3-year period results in an average annual reduction in health spending of 2.05% and 51.02%, respectively. However, if we wait until the third year, the annual reduction is only 0.77% and 17.63% respectively.

The Healthcare Cost of Air Pollution: Evidence from the World's Largest Payment Network

Abstract This paper exploits the universe of credit- and debit-card transactions in China during 2013-2015 and provides the first nationwide analysis of the healthcare cost of PM2.5 for a developing country. We leverage spatial spillovers of PM2.5 from long-range transport to generate exogenous variation in local pollution and employ a flexible distributed lag model to capture semiparametrically the dynamic response of pollution exposure. We find significant impacts of PM2.5 on healthcare spending in both the short and medium terms. A 10 μg/m3 decrease in PM2.5 would reduce annual healthcare spending by over $9.2 billion, about 1.5% of China's annual healthcare expenditure.

The highest-cost Medicaid enrollees with sickle cell disease had annual health care expenditures nearing $200 000.

Sickle cell disease (SCD) is a painful chronic blood disorder that causes serious complications and comorbidities, often leading to premature death. SCD impacts millions of people worldwide, including an estimated 100 000 in the United States, most of whom are Black or Latino. We analyzed Medicaid enrollment, claims, and encounter data via the Transformed Medicaid Statistical Information System (T-MSIS) to examine the 2021 health care utilization and spending of Medicaid enrollees with SCD. Our analysis found that Medicaid enrollees with SCD have high annual medical and pharmacy expenditures that are not evenly distributed across the population. Among the most severe enrollees with genotypes eligible for clinical trials, those in the top 5% of health care spending incurred, on average, nearly $200 000 per year for this chronic condition.

Sociodemographic and Clinical Predictors of Prolonged Length of Corneal Ulcer Hospitalizations

The length of stay (LOS) of hospitalizations may be a useful indicator of the burden of disease of corneal ulcers. Identifying variables associated with longer LOS may help to enhance delivery of care for high-risk patients. To investigate the sociodemographic, social, and clinical factors associated with LOS in hospitalizations for corneal ulcers in the US. This was a retrospective cross-sectional study of adult patients (aged >18 years) admitted with a primary diagnosis of corneal ulcer between quarter 4 of 2015 through 2020 and conducted using data from the National Inpatient Sample (NIS). Patients were stratified into 2 even cohorts based on LOS: LOS of 4 days or less and LOS greater than 4 days. Individual-level sociodemographic, social risk factors, and medical comorbidities associated with longer LOS were examined by multivariable regression. Data were analyzed from October 2015 to December 2020. Potential sociodemographics or medical comorbidities at hospital admission. The primary outcome of interest was factors associated with extended length of stay. The hypothesis being tested was formulated during data collection. A total of 1187 patients (mean [SD] age, 53.5 [20.9] years; 602 female [50.7%]) were included for analysis. The cohort with LOS greater than 4 days had higher total charges than the cohort with LOS of 4 days or less (mean [SD] charges, $79 504 [$86 719] vs $26 474 [$20 743]; P < .001). Sociodemographic variables associated with LOS greater than 4 days were Black race (adjusted odds ratio [aOR], 1.41; 95% CI, 1.03-1.92; P = .03), Medicare insurance (aOR, 1.42; 95% CI, 1.09-1.85; P = .009), and housing insecurity (aOR, 1.99; 95% CI, 1.29-3.06; P = .002). Medical comorbidities associated with LOS greater than 4 days were alcohol use (aOR, 1.50; 95% CI, 1.00-2.26; P = .05), dementia (aOR, 2.35; 95% CI, 1.36-4.07; P = .002), complicated diabetes (aOR, 1.75; 95% CI, 1.21-2.53; P = .003), uncomplicated diabetes (aOR, 1.57; 95% CI, 1.02-2.42; P = .04), drug misuse (aOR, 1.66; 95% CI, 1.08-2.57; P = .02), and legal blindness (aOR, 3.42; 95% CI, 1.19-9.82; P = .02). Based on NIS national estimates, corneal ulcers were estimated to have a direct annual health care expenditure of $35 819 590 in the US. Corneal ulcer hospitalizations represent a significant burden of disease for patients and health care systems. This study highlights sociodemographic and clinical factors that may help clinicians identify high-risk patients vulnerable to complications and morbidity due to corneal ulcers.

One-Year Medication Treatment Patterns, Healthcare Resource Utilization, and Expenditures for Medicaid Patients with Schizophrenia Starting Oral Atypical Antipsychotic Medication

Oral atypical antipsychotic (OAAP) medications are the most commonly prescribed treatment for the management of schizophrenia symptoms. This retrospective study, using Medicaid claims data (2016–2020), followed patients for 12 months after initiating OAAP therapy. Study outcomes included OAAP adherence, switching, augmentation, healthcare resource utilization (HRU), and expenditures. All-cause and schizophrenia-related HRU and expenditures were compared between adherent and nonadherent cohorts. Among 13,007 included patients (39.1 ± 12.8 years of age, 57.0% male, 36.1% Black, 31.8% White, 9.7% Hispanic), 25.7% were adherent to OAAPs (proportion of days covered [PDC] ≥ 0.8). During the 1-year follow-up period, Black individuals were in possession of an OAAP for an average of 166 days compared to 198 and 202 days for White and Hispanic patients, respectively. Approximately 16% of patients switched OAAP medications and 3.2% augmented therapy with an OAAP added to their index medication. Nearly 40% of patients were hospitalized during follow-up and 68.4% had emergency department (ED) visits. A greater proportion of nonadherent patients had all-cause inpatient (41.7% vs. 34.1%, p < 0.001) and ED visits (71.7% vs. 58.8%, p < 0.001) compared to adherent patients. Annual total healthcare expenditures were $21,020 per patient; $3481 higher for adherent versus nonadherent patients. Inpatient expenditures comprised 44.6% and 30.6% of total expenditures for nonadherent and adherent patients, respectively. Hospitalized patients’ total expenditures were $23,261 higher compared to those without a hospitalization. Adherence to OAAP medication is suboptimal and associated with increased utilization of costly hospital and ED resources. Efforts to improve therapies and increase medication adherence could improve clinical and economic outcomes among individuals with schizophrenia.

Real-World Amount of Clotting Factor Concentrates Dispensed and Annual Medical Expenditures for Japanese Patients with Hemophilia B.

Until extended half-life (EHL) factor IX (FIX) concentrates became available in Japan in 2010, patients with hemophilia B received intravenous FIX replacement therapy with standard half-life (SHL) FIX concentrates. To investigate the amount of factor dispensed and the associated medical expenditures for the treatment of hemophilia B in the real-world clinical setting in Japan. This retrospective study comprised patients with hemophilia B (N=197) who had filled prescriptions for FIX concentrates reported in Japan's Medical Data Vision database from 2015 to 2019. Patients were included if they had 2 or more prescriptions for the same FIX concentrates within the first 6 months of the study period and the interval between prescriptions was at least 2 weeks. Since 2015, there was a decrease in the proportion of patients using SHL FIX concentrates and a corresponding increase in international units of dispensed EHL FIX concentrates. Median annualized dispensed dosages (IU/kg body weight) of EHL FIX concentrates were lower than for SHL concentrates for outpatient use only. Annual total health care expenditures per patient and annual expenditures for prescribed FIX concentrates increased each year during the study period. Following a switch from an SHL to an EHL concentrate, the median amount of prescribed FIX concentrate decreased slightly, although median total health care expenditures and FIX concentrate expenditures increased. In the real-world setting in Japan, medical expenditures and the proportion of patients prescribed EHL FIX concentrates for the treatment of hemophilia B have increased.

Politician’s childhood experience and government policies: Evidence from the Chinese Great Famine

We analyze the impact of a politician’s childhood experience on their policy choices. By exploiting exogenous variations in exposure to China’s Great Famine, we find that a provincial leader’s childhood experience of the famine significantly increases the share of government expenditure allocated to health care during his term. This effect is observed only for those who were aged under five during the famine and is not found among older cohorts. The impact is substantial: our back-of-the-envelope calculation indicates that an increase of one standard deviation in exposure to the famine can lead to an increase of roughly 7.84 billion RMB (equivalent to about 1.19 billion US Dollars) in annual provincial health care expenditure for a province with average government spending in 2017. We provide evidence suggesting that this effect may be driven by a politician’s personal experience of negative health outcomes due to the famine. Furthermore, we observe that China’s political promotion system, which favors economic growth, incentivizes provincial leaders to counterbalance increased health care spending by reducing funding for less visible public services, particularly cultural activities. Such strategic allocations ensure the continuity of other policy areas that are more influential in their political career.

Comparing super-utilizers and lower-utilizers among commercial- and Medicare-insured adults with sickle cell disease

AbstractSickle cell disease (SCD) is a rare but costly condition in the United States. Super-utilizers have been defined as a subset of the population with high health care encounters or expenditures. Although super-utilizers have been described in other disease states, little is known about super-utilizers among adults with SCD. This study aimed to characterize the differences in expenditures, overall health care encounters, and pain episode encounters between super-utilizers (top 10% expenditures) and lower-utilizers with SCD (high, top 10%-24.9%; moderate, 25%-49.9%; and low, bottom 50% expenditures). A retrospective longitudinal cohort of adults with SCD were identified using validated algorithms in MarketScan and Medicare claim databases from 2016 to 2020. Encounters and expenditures were analyzed from inpatient, outpatient, and emergency department settings. Differences in encounters and expenditures between lower-utilizers and super-utilizers were compared using logistic regression. Among super-utilizers, differences in encounters and expenditures were compared according to incidences of pain episode encounters. The study population included 5666 patients with commercial insurance and 8600 with Medicare. Adjusted total annual health care expenditure was 43.46 times higher for super-utilizers than for low-utilizers among commercial-insured and 13.37 times higher in Medicare-insured patients. Among super-utilizers, there were patients with few pain episode encounters who had higher outpatient expenditures than patients with a high number of pain episode encounters. Our findings demonstrate the contribution of expensive outpatient care among SCD super-utilizers, in which analyses of high expenditure have largely focused on short-term care. Future studies are needed to better understand super-utilizers in the SCD population to inform the effective use of preventive interventions and/or curative therapies.

Health Care Expenditures for Black and White US Adults Living Under Similar Conditions

Evidence suggests that racial disparities in health outcomes disappear or diminish when Black and White adults in the US live under comparable living conditions; however, whether racial disparities in health care expenditures concomitantly disappear or diminish is unknown. To examine whether disparities in health care expenditures are minimized when Black and White US adults live in similar areas of racial composition and economic condition. This cross-sectional study used a nationally representative sample of 7062 non-Hispanic Black or White adults who live in 2238 of 2275 US census tracts with a 5% or greater Black population and who participated in the Medical Expenditure Panel Study (MEPS) in 2016. Differences in total health care expenditures and 6 specific categories of health care expenditures were assessed. Two-part regression models compared expenditures between Black and White adults living in the same Index of Concentration at the Extremes (ICE) quintile, a measure of racialized economic segregation. Estimated dollar amount differences in expenditures were calculated. All analyses were weighted to account for the complex sampling design of the MEPS. Data analysis was performed from December 1, 2019, to August 7, 2023. Self-reported non-Hispanic Black or non-Hispanic White race. Presence and amount of patient out-of-pocket and insurance payments for annual total health care expenditures; office-based, outpatient, emergency department, inpatient hospital, or dental visits; and prescription medicines. ICE quintile 5 (Q5) reflected tracts that were mostly high income with mostly White individuals, whereas Q1 reflected tracts that were mostly low income with mostly Black individuals. A total of 7062 MEPS respondents (mean [SD] age, 49 [18] years; 33.1% Black and 66.9% White; 56.1% female and 43.9% male) who lived in census tracts with a 5% or greater Black population in 2016 were studied. In Q5, Black adults had 56% reduced odds of having any health care expenditures (odds ratio, 0.44; 95% CI, 0.27-0.71) compared with White adults, at an estimated $2145 less per year, despite similar health status. Among those in Q5 with any expenditures, Black adults spent 30% less on care (cost ratio, 0.70; 95% CI, 0.56-0.86). In Q3 (most racially and economically integrated), differences in total annual health care spending were minimal ($79 annually; 95% CI, -$1187 to $1345). In this cross-sectional study of Black and White adults in the US, health care expenditure disparities diminished or disappeared under conditions of both racial and economic equity and equitable health care access; in areas that were mostly high income and had mostly White residents, Black adults spent substantially less. Results underscore the continuing need to recognize place as a contributor to race-based differences in health care spending.

Incidence, prevalence and characteristics of multimorbidity in different age groups among urban hospitalized patients in China

The aim of the study was to investigate the incidence, prevalence and characteristics of multimorbidity in urban inpatients of different age groups. This study used data from the National Insurance Claim for Epidemiology Research (NICER) to calculate the overall incidence, prevalence, geographic and age distribution patterns, health care burden, and multimorbidity patterns for multimorbidity in 2017. According to our study, the overall prevalence of multimorbidity was 6.68%, and the overall prevalence was 14.87% in 2017. The prevalence of multimorbidity increases with age. The pattern of the geographic distribution of multimorbidity shows that the prevalence of multimorbidity is relatively high in South East China. The average annual health care expenditure of patients with multimorbidity increased with age and rose rapidly, especially among older patients. Patients with cancer and chronic kidney disease have higher treatment costs. Patients with hypertension or ischemic heart disease had a significantly higher relative risk of multimorbidity than other included noncommunicable diseases (NCDs). Hyperlipidemia has generated the highest number of association rules, which may suggest that hyperlipidemia may be both a risk factor for other NCDs and an outcome of them.

Healthcare expenditure trends among adult stroke patients in the United States, 2011-2020

BackgroundIn the US, between 2018 and 2019, approximately $57 billion were expended on stroke and related conditions. The aim of this study was to understand trends in direct healthcare expenditures among stroke patients using novel cost estimation methods and a nationally representative database. MethodsThis study was a retrospective analysis of 193,003 adults, ≥18 years of age, using the Medical Expenditure Panel Survey during 2009-2016. Manning and Mullahy's two-part model were used to calculate adjusted mean and incremental medical expenditures after adjusting for covariates. ResultsThe mean (Standard Deviation) direct annual healthcare expenditure among stroke patients was $16,979.0 ($16,222.0- $17,736.0) and was nearly 3 times greater than non-stroke participants which were $5,039.7 ($4,951.0-$5,128.5) and were mainly spent on inpatient services, prescription medications, and office-based visits. Stroke patients had an additional healthcare expenditure of $4096.0 (3543.9, 4648.1) per person per year, compared to participants without stroke after adjusting for covariates (P<0.001). The total mean annual direct healthcare expenditure for stroke survivors increased from $16,142.0 (15,017.0-17,267.0) in 2007-2008 to $16,979.0 (16,222.0-17,736.0) in 2015-2016. ConclusionOur study showed that stroke survivors had significantly greater healthcare expenses, compared to non-stroke individuals, mainly due to higher expenditures on inpatient services, prescription drugs, and office visits. These findings are concerning because the prevalence of stroke is projected to increase due to aging population and increased survival rates.

Lifetime risk, life expectancy, loss-of-life expectancy and lifetime healthcare expenditure for Stevens-Johnson syndrome/toxic epidermal necrolysis in Taiwan: follow-up of a nationwide cohort from 2008 to 2019.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) not only cause acute, devastating mucocutaneous reactions but also have long-lasting implications on survivors' lives. To quantify the lifetime burden of SJS/TEN. The cumulative incidence rate (CIR), life expectancy (LE), loss-of-life expectancy (LoLE) and lifetime healthcare expenditure (HE) for SJS/TEN were estimated over the period from 2008 to 2019 using data from the National Health Insurance Research Database of Taiwan and life tables of vital statistics. In this nationwide cohort of 6552 incident SJS/TEN cases, a trend towards a decrease in the CIR was observed between 2008 and 2019. Compared with the general population, patients with SJS/TEN experience a tremendous loss of 9.43 (1.06) [mean (SEM)] years of LE after diagnosis of SJS/TEN. Male patients with SJS/TEN had higher LoLE [10.74 (1.22) vs. 7.69 (1.43) years] and annual HE than females. Younger age at diagnosis of SJS/TEN was associated with longer LE but greater LoLE and higher lifetime HE. Patients with intensive care unit admission on diagnosis, malignancy, diabetes mellitus, end-stage renal disease and SJS/TEN-associated sequelae experienced substantially greater LoLE and HE per life year. Patients with SJS/TEN suffer substantial loss-of-LE and HE, particularly young patients, compared with the general population. These data provide a reference estimate of the lifetime burden of SJS/TEN to help health authorities evaluate the cost-effectiveness of future preventive and treatment strategies to minimize the burden of SJS/TEN.

Association between non-pharmacological therapy and healthcare use and expenditure of patients with diabetes mellitus

This study explored the sociodemographic and clinical characteristics of patients with diabetes who incorporated two non-pharmacological therapies into their lifestyle and the association between non-pharmacological therapy and healthcare utilization and expenditure. In the USA, 26.4 million people were reportedly diagnosed with diabetes and treated with diet modification or physical activity in the 2019 Medical Expenditure Panel Survey. Physical activity was defined as moderate-to-vigorous physical exercise five times per week, whereas dietary modification involved healthy eating that reduced glucose levels. Only 4.8 million patients with diabetes did not integrate any non-pharmacological intervention into their therapy regimen. Those who did not include non-pharmacological interventions had higher annual total healthcare expenditures (M = $18,428) than those who incorporated either single (M = $17,058) or dual intervention (M = $15,134). A significant difference was observed in prescribed medicine utilization per year for those who did not include lifestyle modifications or non-pharmacological interventions. Propensity score-matched participants revealed significant differences in hospital stays, outpatient visits, and emergency department expenditures. Patients with diabetes who adhered to two non-pharmacological interventions showed significantly lower healthcare utilization. Being active and following a healthy diet can help prevent the progression of diabetes mellituscomplications and reduce the cost associated with diabetes.

Excess healthcare expenditure in adults treated for solid cancer in childhood: a cohort study in France.

Due to late effects, childhood cancer survivors (CCS) are more likely to have multiple chronic conditions than the general population. However, little is known about the economic burden of care of CCS in the long term. To estimate excess healthcare expenditure for long-term CCS in France compared to the general population and to investigate the associated factors. We included 5353 5-year solid CCS diagnosed before the age of 21years before 2000 from the French CCS cohort and obtained a random reference sample from the general population for each CCS, matched on age, gender and region of residence. We used the French national health data system to estimate annual healthcare expenditure between 2011 and 2018 for CCS and the reference sample, and computed the excess as the net difference between CCS expenditure and the median expenditure of the reference sample. We used repeated-measures linear models to estimate associations between excess healthcare expenditure and CCS characteristics. Annual mean (95% CI) excess healthcare expenditure was €3920 (3539; 4301), mainly for hospitalization (39.6%) and pharmacy expenses (17%). Higher excess was significantly associated with having been treated before the 1990s and having survived a central nervous system tumor, whereas lower excess was associated with CCS who had not received treatment with radiotherapy. Of the variables that influence excess healthcare expenditure, a lever for action is the type of treatment administered. Future research should focus on addressing the long-term cost-effectiveness of new approaches, especially those related to radiotherapy.

Economic burden of nonadherence to standards of diabetes care.

To evaluate the effect of nonadherence to American Diabetes Association (ADA) guidelines on health care expenditures for patients with type 2 diabetes (T2D). Retrospective cross-sectional cohort design, utilizing 2016-2018 Medical Expenditure Panel Survey data. Patients with a diagnosis of T2D who completed the supplemental T2D care survey were included in the study. Participants were categorized based on adherence to the 10 processes in the ADA guidelines into adherent (≥ 9 processes) and nonadherent (≤ 6 processes) categories. Propensity score matching was employed using a logistic regression model. After matching, total annual health care expenditure change from baseline year was compared using a t test. Further, imbalanced variables were controlled for in a multivariable linear regression model. A total of 1619 patients representing 15,781,346 (SE = 438,832) individuals met the inclusion criteria, among whom 12.17% received nonadherent care. After propensity matching, those who received nonadherent care had $4031 higher total annual health care expenditures compared with their baseline year, whereas patients who received adherent care had $128 lower total annual health care expenditures compared with their baseline year. Further, multivariable linear regression adjusted for the imbalanced variables indicated that nonadherent care was associated with a mean (SE) $3470 ($1588) increase in the change from baseline health care expenditure. Nonadherence to the ADA guidelines results in a significant increase in health care expenditures among patients with diabetes. The economic impact of nonadherent care for T2D is a significant and extensive issue that needs to be addressed. These findings emphasize the importance of providing care based on ADA guidelines.

EE267 Racial Disparity in Total Annual Healthcare Expenditure for Cervical Cancer Patients: A 6 Years (2014-2019) US National Study

Cervical cancer is the 4th most common malignancy among women. The aim of this study was to compare the total annual healthcare expenditure among patients diagnosed with cervical cancer between different racial groups in the United States.

Determinants of Healthcare Expenditures among People with Aphasia: Importance of Race, Sex, Residence, and Aphasia Type

ABSTRACT Introduction Roughly 30% of stroke survivors suffer from aphasia—a communication disorder that affects the ability to communicate effectively—but little is known about their healthcare expenditure or how it varies between aphasia subtypes. This study evaluates the relative differential in healthcare expenditure of anomic, Broca’s, Wernicke’s and Conduction aphasia and assesses expenditure between demographic cohorts Methods Individual level data from the 2010 Moss Aphasia Psycholinguistic Project Database was matched with the 2010 Medical Expenditure Panel Survey using a propensity score algorithm based on functional, health, and demographic characteristics. Multilevel, generalized, nonlinear regression models were applied to the resulting data set to assess the correlation between annual healthcare expenditure, time post onset (tpo), sex, race, family size, marital status, income, education, aphasia type, and region of residence. Results were used to predict expenditure by aphasia subtype, race, and sex. Multiple distributional specifications tested the sensitivity and ensured the robustness of estimates. Results Regression results indicate that individuals with Broca’s aphasia had statistically higher healthcare expenditures paying an average of $10,896.45 annually when compared to anomic ($7,927.60), Wernicke’s ($7,096.22), and Conduction ($9,447.19) aphasias. Additionally, healthcare expenditure increased with each year of age (β=0.004, SE=0.005), but decreased with each year after stroke (β=-0.002, SE=0.001). Females (β=0.358, SE=0.131) and Blacks (β=0.103, SE=0.200) paid significantly more annually compared to males and Whites, respectively. Neither region of residence, income, nor level of education were significantly correlated with healthcare expenditure. Conclusion This study showed that, while individuals with Broca’s aphasia had higher average healthcare expenditure than other subtypes, the differential was not statistically significant. Sex and race cohorts did, however, show statistically significant differences in healthcare expenditures. While causality is outside the scope of this analysis, additional work is needed to determine the best strategy to mitigate these disparities.
