Association between physician age and patterns of end-of-life care among older Americans.

BACKGROUND: End-of-life (EOL) care patterns may differ by physician age given differences in how physicians are trained or changes associated with aging. We sought to compare patterns of EOL care delivered to older Americans according to physician age. METHODS: We conducted a cross-sectional study of a 20% sample of Medicare fee-for-service beneficiaries aged ≥66 years who died in 2016-2019 (n = 487,293). We attributed beneficiaries to the physician who had >50% of primary care visits during the last 6 months of life. We compared beneficiary-level outcomes by physician age (<40, 40-49, 50-59, or ≥60) in two areas: (1) advance care planning (ACP) and palliative care; and (2) high-intensity care at the EOL. RESULTS: Beneficiaries attributed to younger physicians had slightly higher proportions of billed ACP (adjusted proportions, 17.1%, 16.1%, 15.5%, and 14.0% for physicians aged <40, 40-49, 50-59, and ≥60, respectively; p-for-trend adjusted for multiple comparisons <0.001) and palliative care counseling or hospice use in the last 180 days of life (64.5%, 63.6%, 61.9%, and 60.8%; p-for-trend <0.001). Similarly, physicians' younger age was associated with slightly lower proportions of emergency department visits (57.4%, 57.0%, 57.4%, and 58.1%; p-for-trend <0.001), hospital admissions (51.2%, 51.1%, 51.4%, and 52.1%; p-for-trend <0.001), intensive care unit admissions (27.8%, 27.9%, 28.2%, and 28.3%; p-for-trend = 0.03), or mechanical ventilation or cardiopulmonary resuscitation (14.2, 14.9%, 15.2%, and 15.3%; p-for-trend <0.001) in the last 30 days of life, and in-hospital death (20.2%, 20.6%, 21.3%, and 21.5%; p-for-trend <0.001). CONCLUSIONS: We found that differences in patterns of EOL care between beneficiaries cared for by younger and older physicians were small, and thus, not clinically meaningful. Future research is warranted to understand the factors that can influence patterns of EOL care provided by physicians, including initial and continuing medical education.

Percutaneous Microaxial Ventricular Assist Device Versus Intra-Aortic Balloon Pump for Nonacute Myocardial Infarction Cardiogenic Shock.

BACKGROUND: Evidence on the comparative outcomes following percutaneous microaxial ventricular assist devices (pVAD) versus intra-aortic balloon pump for nonacute myocardial infarction cardiogenic shock is limited. METHODS AND RESULTS: We included 704 and 2140 Medicare fee-for-service beneficiaries aged 65 to 99 years treated with pVAD and intra-aortic balloon pump, respectively, for nonacute myocardial infarction cardiogenic shock from 2016 to 2020. Patients treated using pVAD compared with those treated using intra-aortic balloon pump were more likely to be concurrently treated with mechanical ventilation, renal replacement therapy, and blood transfusions. We computed propensity scores for undergoing pVAD using patient- and hospital-level factors and performed a matching weight analysis. The use of pVAD was associated with higher 30-day mortality (adjusted odds ratio, 1.92 [95% CI, 1.59-2.33]) but not associated with in-hospital bleeding (adjusted odds ratio, 1.00 [95% CI, 0.81-1.24]), stroke (adjusted odds ratio, 0.91 [95% CI, 0.56-1.47]), sepsis (OR, 0.91 [95% CI, 0.64-1.28]), and length of hospital stay (adjusted mean difference, +0.4 days [95% CI, -1.4 to +2.3]). A quasi-experimental instrumental variable analysis using the cross-sectional institutional practice preferences showed similar patterns, though not statistically significant (adjusted odds ratio, 1.38; 95% CI, 0.28-6.89). CONCLUSIONS: Our investigation using the national sample of Medicare beneficiaries showed that the use of pVAD compared with intra-aortic balloon pump was associated with higher mortality in patients with nonacute myocardial infarction cardiogenic shock. Providers should be cautious about the use of pVAD for nonacute myocardial infarction cardiogenic shock, while adequately powered high-quality randomized controlled trials are warranted to determine the clinical effects of pVAD.

Cardiac Reoperation or Transcatheter Mitral Valve Replacement for Patients With Failed Mitral Prostheses.

BACKGROUND: Evidence is limited regarding patient outcomes comparing redo surgical mitral valve replacement (redo SMVR) vs transcatheter mitral valve replacement (TMVR) for failed prostheses. OBJECTIVES: The goal of this study was to compare the outcomes of redo SMVR vs TMVR in patients with failed prostheses, as well as evaluate the association between case volume and outcomes. METHODS: Medicare beneficiaries aged ≥65 years who underwent redo SMVR or TMVR for failed mitral prostheses between 2016 and 2020 were included. The primary endpoint was mid-term (up to 3 years) major adverse cardiovascular events (MACE), including all-cause death, heart failure rehospitalization, stroke, or reintervention. Propensity score-matched analysis was used. RESULTS: A total of 4,293 patients were included (redo SMVR: 64%; TMVR: 36%). TMVR recipients were older, with a higher comorbidity burden. In matched cohort (n = 1,317 in each group), mid-term risk of MACE was similar (adjusted HR: 0.92; 95% CI: 0.80-1.04; P = 0.2). However, landmark analysis revealed a lower risk of MACE with TMVR in the first 6 months (adjusted HR: 0.75; 95% CI: 0.63-0.88; P < 0.001) albeit with a higher risk beyond 6 months (adjusted HR: 1.28; 95% CI: 1.04-1.58; P = 0.02). Increasing procedural volume was associated with decreased risk of mid-term MACE after redo SMVR (P = 0.001) but not after TMVR (P = 0.3). CONCLUSIONS: In this large cohort of Medicare beneficiaries with failed mitral prostheses, outcomes were similar between redo SMVR and TMVR at 3 years, with TMVR showing a lower initial risk but a higher risk of MACE after 6 months. These findings highlight the importance of striking a balance between surgical risk, anticipated longevity, and hospital expertise when selecting interventions.

Changes in Site of Death Among Older Adults Without a COVID-19 Diagnosis During the COVID-19 Pandemic.

BACKGROUND: Understanding how the coronavirus disease 2019 (COVID-19) pandemic affected site of death-an important patient-centered outcome related to end-of-life care-would inform healthcare system resiliency in future public health emergencies. OBJECTIVE: To evaluate the changes in site of death during the COVID-19 pandemic among older adults without a COVID-19 diagnosis. DESIGN: Using a quasi-experimental difference-in-differences method, we estimated net changes in site of death during the pandemic period (March-December 2020) from the pre-pandemic period (January-February 2020), using data on the same months in prior years (2016-2019) as the control. PARTICIPANTS: A 20% sample of Medicare Fee-for-Service beneficiaries aged 66 years and older who died in 2016-2020. We excluded beneficiaries with a hospital diagnosis of COVID-19. MAIN MEASURES: We assessed each of the following sites of death separately: (1) home or community; (2) acute care hospital; and (3) nursing home. KEY RESULTS: We included 1,133,273 beneficiaries without a hospital diagnosis of COVID-19. We found that the proportion of Medicare beneficiaries who died at home or in the community setting increased (difference-in-differences [DID] estimate, + 3.1 percentage points [pp]; 95% CI, + 2.6 to + 3.6 pp; P < 0.001) and the proportion of beneficiaries who died (without COVID-19 diagnosis) in an acute care hospital decreased (- 0.8 pp; 95% CI, - 1.2 to - 0.4 pp; P < 0.001) during the pandemic. We found no evidence that the proportion of deaths in nursing homes changed during the pandemic. CONCLUSIONS: Using national data on older adults without a COVID-19 diagnosis, we found that site of death shifted toward home or community settings during the COVID-19 pandemic. Our findings may inform clinicians and policymakers in supporting end-of-life care during future public health emergencies.

Association between physicians' geriatric training and patterns of end-of-life care delivered to persons with dementia.

BACKGROUND: Geriatric training is designed to prepare physicians to meet the complex needs of older adults, including persons with dementia at the end-of-life (EOL) stage. We sought to compare patterns of EOL care delivered to persons with dementia between physicians with versus without geriatric training. METHODS: We conducted a cross-sectional study of a 20% random sample of fee-for-service Medicare beneficiaries with dementia who died in 2016-2018 (n = 99,631). We attributed beneficiaries to a physician who had the largest number of primary care visits during the last 6 months of life and determined whether the physician was trained in geriatrics. Our outcome measures included: (i) advance care planning (ACP) and palliative care (e.g., ACP, hospice enrollment in the last 90 days of life), and (ii) high-intensity EOL care (e.g., emergency department visits or hospital admissions in the last 30 days of life). RESULTS: Beneficiaries with dementia under the care of physicians with geriatric training had a higher proportion of ACP (adjusted proportion, 15.8% vs. 13.0%; p < 0.001 after accounting for multiple comparisons), palliative care counseling (22.4% vs. 20.9%; p = 0.01), and hospice enrollment (63.7% vs. 60.6%; p < 0.001). Geriatric training was also associated with a lower proportion of emergency department visits (55.1% vs. 59.1%; p < 0.001), hospital admissions (48.8% vs. 52.3%; p < 0.001), ICU admissions (24.9% vs. 27.4%; p < 0.001), use of mechanical ventilation (11.2% vs. 13.0%; p < 0.001), and use of cardiopulmonary resuscitation (2.1% vs. 2.4%; p = 0.03) in the last 30 days of life. There was no evidence that the placement of feeding tubes differed between the two groups. CONCLUSIONS: Physicians' geriatric training was associated with the receipt of more ACP and palliative care and less intensive EOL care among persons with dementia. Provision of geriatric training for physicians may have the potential to improve the quality of EOL care delivered to persons with dementia.

Timing and setting of billed advance care planning among Medicare decedents in 2017-2019.

BACKGROUND: The Centers for Medicare & Medicaid Services (CMS) began to reimburse clinicians for advance care planning (ACP) discussions, effective January 1, 2016. We sought to characterize the timing and setting of first-billed ACP discussions among Medicare decedents to inform future research on ACP billing codes. METHODS: Using a random 20% sample of Medicare fee-for-service beneficiaries aged 66 years and older who died in 2017-2019, we described the timing (relative to death) and setting (inpatient, nursing home, office, or outpatient with or without Medicare Annual Wellness Visit [AWV], home or community, or elsewhere) of the first-billed ACP discussion for each beneficiary. RESULTS: Our study included 695,985 decedents (mean [SD] years of age, 83.2 [8.8]; 54.2% female); the proportion of decedents who had at least one billed ACP discussion increased from 9.7% in 2017 to 21.9% in 2019. We found that the proportion of first-billed ACP discussions held during the last month of life decreased from 37.0% in 2017 to 26.2% in 2019, while the proportion of first-billed ACP discussions held more than 12 months before death increased from 11.1% in 2017 to 35.2% in 2019. We also found that the proportion of first-billed ACP discussions held in the office or outpatient setting along with AWV increased over time (from 10.7% in 2017 to 14.1% in 2019), while the proportion held in the inpatient setting decreased (from 41.7% in 2017 to 38.0% in 2019). CONCLUSIONS: We found that with increasing exposure to the CMS policy change, uptake of the ACP billing code has increased; first-billed ACP discussions are occurring sooner before the end-of-life stage and are more likely to occur with AWV. Future studies should evaluate changes in ACP practice patterns, rather than only an increasing uptake in ACP billing codes, following the policy implementation.

Life satisfaction among persons living with dementia and those without dementia.

BACKGROUND: Despite possible major adverse cognitive, physical, social, and behavioral consequences, little is known about how persons living with dementia perceive satisfaction with life, a key component of well-being. We sought to examine (i) whether persons living with dementia perceive a lower level of satisfaction compared to their peers without dementia and (ii) whether the associations between individual characteristics and life satisfaction are different between persons living with and without dementia. METHODS: Using a nationally representative sample of community-dwelling older adults aged ≥70 years in the U.S. from the Health and Retirement Study, we compared scores on the Satisfaction with Life Scale (SWLS), a self-reported 5-item scale ranging from 1 to 7 (more satisfaction), between persons with probable dementia (n = 341) and those without (n = 5530), adjusting for individual characteristics. We also tested whether the associations between the individual characteristics and SWLS differ by dementia status. RESULTS: Scores on SWLS did not differ between persons with probable dementia and those without when adjusting for individual characteristics including limitations in activities of daily living (ADL) (adjusted difference, -0.09; 95% CI, -0.33 to +0.15; p-value, 0.45). However, dementia status was associated with lower life satisfaction through the mediation of limitations in ADL (total effect, -0.29; bootstrapped 95% CI, -0.47 to -0.12). Most individual characteristics associated with lower life satisfaction were similar in the two groups, including younger age, more limitations in ADL, and depression. Less wealth was associated with lower satisfaction among persons without dementia but not among those with probable dementia. CONCLUSIONS: Dementia status was only modestly associated with lower life satisfaction through the mediation of limitations in ADL among participants who were able to provide response. Future research is warranted to determine whether life satisfaction can be used as a meaningful outcome when evaluating well-being among persons living with dementia.

Geriatric fracture program centering age-friendly care associated with lower length of stay and lower direct costs.

OBJECTIVE: To evaluate outcomes associated with an integrated inpatient and outpatient program aimed at optimizing the care of geriatric fracture patients in a mixed community and academic health system setting. DATA SOURCES AND STUDY SETTING: This study took place at a tertiary-care, 886-bed hospital system. The Geriatric Fracture Program (GFP) was designed in 2018 using the 4Ms Framework (What Matters, Medication, Mentation, and Mobility). Patients ≥65 years old with non-spine fractures managed by orthopedic faculty surgeons and participating hospitalist groups were included. A fracture liaison team educated patients regarding bone health and ensured ambulatory geriatrics follow-up. Outpatient geriatric visits focused on mobility, fall risk, bone health imaging, and medications. STUDY DESIGN: We compared GFP-enrolled patients (n = 746) to patients seen by non-GFP-participating physicians (n = 852) and used a generalized estimating equations approach and Poisson models to analyze associations between participation in the GFP program and four inpatient outcomes (time to surgery, length of stay, Vizient length of stay index, and total direct costs). We examined outcomes across all fractures and also stratified them by fracture type (hip vs. non-hip). We descriptively examined post-discharge care outcomes: fall, gait, and balance assessments; bone health imaging; and medications. DATA COLLECTION/EXTRACTION METHODS: We collected data through chart reviews/electronic health record extracts from July 2018 to June 2021. PRINCIPAL FINDINGS: GFP-enrolled patients with all fracture types had a significantly lower length of stay (marginal effect [ME]: -2.12, 95%CI: -2.61, -1.63), length of stay index (ME: -0.33, 95%CI: -0.42, -0.25), and total direct costs (ME: -$5316, 95%CI: -$6806, -$3826); the magnitude of the effects was greater for non-hip fractures. There was no significant difference in time to surgery. Of 746 GFP patients, 170 (23%) had a post-discharge visit with a participating geriatrician ≥6 months. CONCLUSIONS: A systematic approach to improving care for older adults with fractures improved length of stay and total direct costs.

Changes in Blood Pressure Outcomes Among Hypertensive Individuals During the COVID-19 Pandemic: A Time Series Analysis in Three US Healthcare Organizations.

BACKGROUND: The COVID-19 pandemic may have negatively affected medical care for and self-management of chronic hypertension. We sought to examine the impact of the pandemic on blood pressure (BP) among individuals with hypertension. METHODS: Using an interrupted time series analysis, we compared the level and trend (slope) of BP outcomes before the public health emergency declaration (prepandemic period: August 2018 through January 2020) versus after the stay-at-home orders (pandemic period: April 2020 through November 2020) among adults with hypertension followed at 3 large health systems (n=137 593). Outcomes include systolic and diastolic BP recorded in electronic health records and the proportion of individuals with BP <140/90 mm Hg. RESULTS: The number of BP measurements substantially dropped early in the pandemic and then gradually increased. During the pandemic period, systolic and diastolic BP increased by 1.79 mm Hg (95% CI, 1.57-2.01; P<0.001) and 1.30 mm Hg (95% CI, 1.18-1.42; P<0.001), respectively, compared with the prepandemic period. Similarly, the proportion of patients with controlled BP decreased by 3.43 percentage points (95% CI, -3.97 to -2.90; P<0.001). A trend showing increasing control in the prepandemic period (+3.19 percentage points per year [95% CI, +2.96 to +3.42]; P<0.001) flattened during the pandemic period (+0.27 percentage points per year [95% CI, -0.81 to -1.37]; P=0.62). CONCLUSIONS: The first 8 months of the pandemic were associated with worsening BP outcomes among individuals with hypertension. Opportunities to ensure ongoing access to health care with telemedicine and home BP monitoring may mitigate adverse impacts on BP control for future disasters/emergencies.

Trends in advance care planning and end-of-life care among persons living with dementia requiring surrogate decision-making.

BACKGROUND: Previous studies have demonstrated positive impacts of advance care planning (ACP) on end-of-life (EOL) care. We sought to examine trends in ACP and EOL care intensity among persons living with dementia who required surrogate decision-making in their final days of life. METHODS: We analyzed the participants of the Health and Retirement Study (HRS), a nationally representative longitudinal panel study of U.S. residents, with dementia 70 years and older who required surrogate decision-making in the final days of life and died between 2000 and 2014. Based on surrogate reports after the death of a participant, our study measured the completion of three specific types of patient-engaged ACP (written EOL care instructions, assignment of a durable power of attorney for healthcare, patient engagement in EOL care discussions) and four measures of EOL care in the final days of life (death in hospital, receipt of life-prolonging treatments, limiting or withholding certain treatments, and receipt of comfort-oriented care). All analyses accounted for the complex survey design of HRS. RESULTS: Among 870 adults (weighted N = 2,812,380) with dementia who died in 2000-2014 and required surrogate decision-making at EOL, only 34.8% of patients participated in all three aspects of ACP, and there was not a significant increase in ACP completion between 2000 and 2014. The receipt of life-prolonging treatments in the final days of life has increased over time (adjusted change per year, 1.4 percentage points [pp]; 95% CI, 0.5 to 2.2 pp; P-for-trend = 0.002), while the percentage of death in hospital, limiting or withholding certain treatments, or comfort-oriented care did not change. CONCLUSIONS: Our findings suggest that the rates of ACP completion have not increased over time despite its potential benefits and life-prolonging treatments are still common among PLWD who require surrogate decision-making, a population who might benefit greatly from early ACP.

Comparison of Advance Care Planning and End-of-Life Care Intensity Between Dementia Versus Cancer Patients.

BACKGROUND: While advanced care planning (ACP) is recommended in dementia and cancer care, there are unique challenges in ACP for individuals with dementia, such as the insidious onset and progression of cognitive impairment, potentially leading to high-intensity care at the end of life (EOL) for this population. OBJECTIVE: To compare ACP completion and receipt of high-intensity care at the EOL between decedents with dementia versus cancer. DESIGN: Retrospective longitudinal cohort study. PARTICIPANTS: Participants of the U.S. Health and Retirement Study who died between 2000 and 2014 with dementia (n = 2099) and cancer (n = 1137). MAIN MEASURES: Completion of three types of ACP (living will, durable power of attorney for healthcare [DPOAH], discussions of preferences for EOL care) and three measures of EOL care intensity (in-hospital death, intensive care unit [ICU] care in the last 2 years of life, life support use in the last 2 years of life). KEY RESULTS: Use of living will was lower in dementia than in cancer (adjusted proportion, 49.9% vs. 56.9%; difference, - 7.0 percentage points [pp, 95% CI, - 13.3 to - 0.7]; p = 0.03). Use of DPOAH was similar between the two groups, but a lower proportion of decedents with dementia had discussed preferences compared to decedents with cancer (53.0% vs. 68.1%; - 15.1 pp [95% CI, - 19.3 to - 10.9]; p < 0.001). In-hospital death was higher in dementia than in cancer (29.5% vs. 19.8%; + 9.7 pp [95% CI, + 5.9 to + 13.5]; p < 0.001), although use of ICU care was lower (20.9% vs. 26.1%; - 5.2 pp [95% CI, - 9.8 to - 0.7]; p = 0.03). Use of life support was similar between the two groups. CONCLUSIONS: Individuals with dementia complete ACP less frequently and might be receiving higher-intensity EOL care than those with cancer. Interventions targeting individuals with dementia may be necessary to further improve EOL care for this population.

Economic evaluation of quality improvement interventions to prevent catheter-associated urinary tract infections in the hospital setting: a systematic review.

BACKGROUND: Hospitals have implemented diverse quality improvement (QI) interventions to reduce rates of catheter-associated urinary tract infections (CAUTIs). The economic value of these QI interventions is uncertain. OBJECTIVE: To systematically review economic evaluations of QI interventions designed to prevent CAUTI in acute care hospitals. METHODS: A search of Ovid MEDLINE, Econlit, Centre for Reviews & Dissemination, New York Academy of Medicine's Grey Literature Report, WorldCat, IDWeek conference abstracts and prior systematic reviews was conducted from January 2000 to October 2020.We included English-language studies of any design that evaluated organisational or structural changes to prevent CAUTI in acute care hospitals, and reported programme and infection-related costs.Dual reviewers assessed study design, effectiveness, costs and study quality. For each eligible study, we performed a cost-consequences analysis from the hospital perspective, estimating the incidence rate ratio (IRR) and incremental net cost/savings per hospital over 3 years. Unadjusted weighted regression analyses tested predictors of these measures, weighted by catheter days per study. RESULTS: Fifteen unique economic evaluations were eligible, encompassing 74 hospitals. Across 12 studies amenable to standardisation, QI interventions were associated with a 43% decline in infections (mean IRR 0.57, 95% CI 0.44 to 0.70) and wide ranges of net costs (mean US$52 000, 95% CI -$288 000 to $392 000), relative to usual care. CONCLUSIONS: QI interventions were associated with large declines in infection rates and net costs to hospitals that varied greatly but that, on average, were not significantly different from zero over 3 years. Future research should examine specific practices associated with cost-savings and clinical effectiveness, and examine whether or not more comprehensive interventions offer hospitals and patients the best value.

Association Between Trust in Government and Practice of Preventive Measures During the COVID-19 Pandemic in Japan.

BACKGROUND: Research suggests that preventive measures are critical to reducing the spread of coronavirus disease 2019 (COVID-19), but evidence regarding the association between trust in government and the practice of preventive measures is limited. OBJECTIVE: To examine whether the practice of preventive measures against COVID-19 differs by one's level of trust in government. DESIGN: A cross-sectional analysis using the Japan COVID-19 and Society Internet Survey (JACSIS) conducted in August and September 2020. PARTICIPANTS: A nationally representative sample of Japanese individuals aged 15 through 79 years. MAIN MEASURES: The primary outcome was the composite score for COVID-19 preventive measures, defined as the percentage of preventive measures an individual reported to be practicing (out of nine measures: social distancing, wearing masks, avoiding closed spaces, avoiding crowded spaces, avoiding close contact settings, hand washing, avoiding touching one's face, respiratory hygiene, and surface disinfection). The secondary outcomes were (1) support for stay-at-home requests, (2) use of a contact-tracing app, and (3) receipt of the influenza vaccine in the previous season. KEY RESULTS: Our analysis included a total of 25,482 individuals. After adjusting for potential confounders, we found that individuals with high trust in government were likely to practice preventive measures more frequently compared to those with low trust (adjusted composite scores, 83.8% for high- vs. 79.5% for low-trust individuals; adjusted difference, +4.3 percentage points [pp]; 95% CI, +2.4 to +6.2pp; P<0.001). We also found that high trust in government was associated with higher likelihoods of support for stay-at-home requests, use of a contact-tracing app, and receipt of the influenza vaccine in the previous season. CONCLUSIONS: High trust in government was associated with a higher intensity of practicing COVID-19 preventive measures among Japanese individuals at the national level. Our findings may provide useful information to develop and design effective public health interventions.

Comparison of the Quality of Chronic Disease Management Between Adults With and Without Dementia.

Importance: Adults with dementia may experience poorer quality of chronic disease management because of the difficulty in reporting symptoms and engaging in shared decision-making associated with cognitive impairment. Objective: To compare the quality of chronic disease management received by adults with and without dementia. Design, Setting, and Participants: For this cross-sectional study, nationally representative data from noninstitutionalized patients 65 years or older were obtained from the 2002-2015 Medical Expenditure Panel Survey. The control group comprised adults of similarly limited life expectancy without dementia comprised . Data analysis was performed in June 2020. Exposures: Dementia diagnosis. Main Outcomes and Measures: Quality of chronic disease management based on 14 individual quality indicators. The association between dementia status and the quality of chronic disease management (3 composite categories: preventive care, diabetes care, and medication treatment) was examined using multivariable linear regression models. Survey weights, sampling strata, and primary sampling unit variables were used to produce national estimates adjusted for nonresponse. Results: This study included 2506 adults (mean [SD] age, 81.4 [4.7] years; 1259 [49.3%] female; 1243 [50.7%] male), of whom 1335 (53.3%) had a diagnosis of dementia and 1171 (46.7%) did not have a diagnosis of dementia. After adjusting for potential confounders, adults with dementia received lower-quality preventive care compared with adults of similar life expectancy without dementia (adjusted absolute difference [aAD], -6.1 percentage points [pp]; 95% CI, -9.7 to -2.5 pp; P = .001). We found no evidence that the quality of care differed in diabetes care (aAD, 1.7 pp; 95% CI, -4.5 to 7.9 pp; P = .59) and medication treatment (aAD, 1.0 pp; 95% CI, -5.0 to 7.0 pp; P = .75). Conclusions and Relevance: In this cross-sectional study, the quality of chronic disease management for adults with dementia was not substantially different from that for those without dementia despite potential barriers. Future studies are warranted to gain a better understanding of the underlying mechanism of these findings for preventive care.

The Affordable Care Act's Insurance Marketplace Subsidies Were Associated With Reduced Financial Burden For US Adults.

Research suggests that the Affordable Care Act (ACA) Medicaid expansions improved financial protection for the poor. However, evidence is limited on whether subsidies offered through the ACA Marketplaces, the law's other major coverage expansion, were associated with reduced financial burden. Using national survey data from the period 2008-17, we examined changes in household health care spending among low-income adults eligible for both Marketplace premium subsidies and cost-sharing reductions (139-250 percent of the federal poverty level) and middle-income adults eligible only for premium subsidies (251-400 percent of the federal poverty level), using high-income adults ineligible for subsidies (greater than 400 percent of the federal poverty level) as controls. Among low-income adults, Marketplace subsidy implementation was associated with 17 percent lower out-of-pocket spending and 30 percent lower probability of catastrophic health expenditures. In contrast, middle-income adults did not experience reduced financial burden by either measure. These findings highlight the successes and limitations of Marketplace subsidies as debate continues over the ACA's future.

Association Between the ACA Medicaid Expansions and Changes in Cardiovascular Risk Factors Among Low-Income Individuals.

BACKGROUND: Evidence is limited as to whether the introduction of the Affordable Care Act (ACA)'s Medicaid expansions was associated with improvements in cardiovascular risk factors at the population level. OBJECTIVE: To examine the association between the ACA Medicaid expansions and changes in cardiovascular risk factors among low-income individuals during the first 3 years of the implementation of the ACA Medicaid expansions at the national level. DESIGN: A quasi-experimental difference-in-differences (DID) analysis to compare outcomes before (2005-2012) and after (2015-2016) the implementation of the ACA Medicaid expansions between individuals in states that expanded Medicaid and individuals in non-expansion states. PARTICIPANTS: A nationally representative sample of individuals aged 19-64 years with family incomes below 138% of the federal poverty level from the 2005-2016 National Health and Nutrition Examination Survey (NHANES). INTERVENTION: ACA Medicaid expansions. MAIN MEASURES: Cardiovascular risk factors included (1) systolic and diastolic blood pressure, (2) hemoglobin A1c (HbA1c) level, and (3) cholesterol levels (low-density lipoprotein cholesterol, triglyceride, and high-density lipoprotein cholesterol). KEY RESULTS: A total of 9177 low-income individuals were included in our analysis. We found that the ACA Medicaid expansions were associated with a lower systolic blood pressure (DID estimate, - 3.03 mmHg; 95% CI, - 5.33 mmHg to - 0.73 mmHg; P = 0.01; P = 0.03 after adjustment for multiple comparisons) and lower HbA1c level (DID estimate, - 0.14 percentage points [pp]; 95% CI, - 0.24 pp to - 0.03 pp; P = 0.01; P = 0.03 after adjustment for multiple comparisons). We found no evidence that diastolic blood pressure and cholesterol levels changed following the ACA Medicaid expansions. CONCLUSION: Using the nationally representative data of individuals who were affected by the ACA, we found that the ACA Medicaid expansions were associated with a modest improvement in cardiovascular risk factors related to hypertension and diabetes during the first 3 years of implementation.

Out-of-pocket spending and financial burden among low income adults after Medicaid expansions in the United States: quasi-experimental difference-in-difference study.

OBJECTIVE: To examine the association between expansion of the Medicaid program under the Affordable Care Act and changes in healthcare spending among low income adults during the first four years of the policy implementation (2014-17). DESIGN: Quasi-experimental difference-in-difference analysis to examine out-of-pocket spending and financial burden among low income adults after Medicaid expansions. SETTING: United States. PARTICIPANTS: A nationally representative sample of individuals aged 19-64 years, with family incomes below 138% of the federal poverty level, from the 2010-17 Medical Expenditure Panel Survey. MAIN OUTCOMES AND MEASURES: Four annual healthcare spending outcomes: out-of-pocket spending; premium contributions; out-of-pocket plus premium spending; and catastrophic financial burden (defined as out-of-pocket plus premium spending exceeding 40% of post-subsistence income). P values were adjusted for multiple comparisons. RESULTS: 37 819 adults were included in the study. Healthcare spending did not change in the first two years, but Medicaid expansions were associated with lower out-of-pocket spending (adjusted percentage change -28.0% (95% confidence interval -38.4% to -15.8%); adjusted absolute change -$122 (£93; €110); adjusted P<0.001), lower out-of-pocket plus premium spending (-29.0% (-40.5% to -15.3%); -$442; adjusted P<0.001), and lower probability of experiencing a catastrophic financial burden (adjusted percentage point change -4.7 (-7.9 to -1.4); adjusted P=0.01) in years three to four. No evidence was found to indicate that premium contributions changed after the Medicaid expansions. CONCLUSION: Medicaid expansions under the Affordable Care Act were associated with lower out-of-pocket spending and a lower likelihood of catastrophic financial burden for low income adults in the third and fourth years of the act's implementation. These findings suggest that the act has been successful nationally in improving financial risk protection against medical bills among low income adults.

Association Between the ACA Medicaid Expansions and Primary Care and Emergency Department Use During the First 3 Years.

BACKGROUND: Evidence is limited and mixed as to how the Patient Protection and Affordable Care Act (ACA) Medicaid expansions affected the utilization of primary care physicians (PCPs) and emergency departments (EDs) at the national level. OBJECTIVE: To examine the association between the ACA Medicaid expansions and changes in the utilization of PCP and ED visits at the national level during the first 3 years (2014-2016) of the implementation. DESIGN: A difference-in-differences analysis to compare outcomes between individuals in 32 states that expanded Medicaid versus individuals in 19 non-expansion states. PARTICIPANTS: A nationally representative sample of US-born individuals 26-64 years old with family incomes lower than 138% of the federal poverty level from the 2010-2016 Medical Expenditure Panel Survey. INTERVENTION: ACA Medicaid expansions MAIN MEASURES: We examined PCP-related outcomes ((i) whether a participant had any PCP visit during a year and (ii) the annual number of PCP visits per person) and ED-related outcomes ((i) whether a participant had any ED visit during a year and (ii) the annual number of ED visits per person). KEY RESULTS: A total of 17,803 participants were included in our analysis. We found that the proportion of individuals with any PCP visit during a year marginally increased (difference-in-differences estimate, + 3.6 percentage points [pp]; 95% CI, - 0.4 pp to + 7.6 pp; P = 0.08) following the Medicaid expansions, without any change in the annual number of PCP visits per person. We found no evidence that ED utilization (both the proportion of individuals with any ED visit during a year and the annual number of ED visits per person) changed meaningfully after the Medicaid expansions. CONCLUSION: Using the nationally representative data of individuals who were affected by the ACA, we found that the ACA Medicaid expansions were associated with a modest improvement in access to PCPs without an increase in ED use.
