Practice Expense Data Collection and Methodology: Phase II Final Report.

Each year, Medicare allocates tens of billions of dollars for indirect practice expense (PE) across services on the basis of data from the Physician Practice Information (PPI) Survey, which reflects 2006 expenses. Because these data are not regularly updated, and because there have been significant changes in the U.S. economy and health care system since 2006, there are concerns that continued reliance on PPI Survey data might result in PE payments that do not accurately capture the resources that are typically required to provide services. In this final phase of a study on PE methodology, the authors address how the Centers for Medicare & Medicaid Services (CMS) might improve the methodology used in PE rate-setting, update data that inform PE rates, or both. The authors conclude that this information is best provided by a survey; therefore, they focus on the advantages and disadvantages of survey-based approaches. They also describe the use of a lean model survey instrument, as well as partnering with another agency to collect data. Finally, the authors describe a virtual town hall meeting held in June 2021 to give stakeholders an opportunity to provide feedback on PE data collection and rate-setting. The system of data and methods that CMS uses to support PE rate-setting is complex; thus, CMS must take into account a number of competing priorities when considering changes to the system. With this in mind, the authors offer a number of near- and longer-term recommendations.

Trends In Hospital Prices Paid By Private Health Plans Varied Substantially Across The US.

Commercial health plans pay higher prices than public payers for hospital care, which accounts for more than 5 percent of US gross domestic product. Crafting effective policy responses requires monitoring trends and identifying sources of variation. Relying on data from the Healthcare Provider Cost Reporting Information System, we describe how commercial hospital payment rates changed relative to Medicare rates during 2012-19 and how trends differed by hospital referral region (HRR). We found that average commercial-to-Medicare price ratios were relatively stable, but trends varied substantially across HRRs. Among HRRs with high price ratios in 2012, ratios increased by 38 percentage points in regions in the top quartile of growth and decreased by 38 percentage points in regions in the bottom quartile. Our findings suggest that restraining the growth rate of HRR commercial hospital price ratios to the national average during our sample period would have reduced aggregate spending by $39 billion in 2019.

D-CARE: The Dementia Care Study: Design of a Pragmatic Trial of the Effectiveness and Cost Effectiveness of Health System-Based Versus Community-Based Dementia Care Versus Usual Dementia Care.

BACKGROUND/OBJECTIVES: Although several approaches have been developed to provide comprehensive care for persons living with dementia (PWD) and their family or friend caregivers, the relative effectiveness and cost effectiveness of community-based dementia care (CBDC) versus health system-based dementia care (CBDC) and the effectiveness of both approaches compared with usual care (UC) are unknown. DESIGN: Pragmatic randomized three-arm superiority trial. The unit of randomization is the PWD/caregiver dyad. SETTING: Four clinical trial sites (CTSs) based in academic and clinical health systems. PARTICIPANTS: A total of 2,150 English- or Spanish-speaking PWD who are not receiving hospice or residing in a nursing home and their caregivers. INTERVENTIONS: Eighteen months of (1) HSDC provided by a nurse practitioner or physician's assistant dementia care specialist who works within the health system, or (2) CBDC provided by a social worker or nurse care consultant who works at a community-based organization, or (3) UC with as needed referral to the Alzheimer's Association Helpline. MEASUREMENTS: Primary outcomes: PWD behavioral symptoms and caregiver distress as measured by the Neuropsychiatric Inventory Questionnaire (NPI-Q) Severity and Modified Caregiver Strain Index scales. SECONDARY OUTCOMES: NPI-Q Distress, caregiver unmet needs and confidence, and caregiver depressive symptoms. Tertiary outcomes: PWD long-term nursing home placement rates, caregiver-reported PWD functional status, cognition, goal attainment, "time spent at home," Dementia Burden Scale-Caregiver, a composite measure of clinical benefit, Quality of Life of persons with dementia, Positive Aspects of Caregiving, and cost effectiveness using intervention costs and Medicare claims. RESULTS: The results will be reported in the spring of 2024. CONCLUSION: D-CARE will address whether emphasis on clinical support and tighter integration with other medical services has greater benefit than emphasis on social support that is tied more closely to community resources. It will also assess the effectiveness of both interventions compared with UC and will evaluate the cost effectiveness of each intervention.

Accounting for the burden and redistribution of health care costs: Who uses care and who pays for it.

OBJECTIVE: To measure the burden of financing health care costs and quantify redistribution among population groups. DATA SOURCES: A synthetic population using data combined from multiple sources, including the Survey of Income and Program Participation (SIPP), Medical Expenditure Panel Survey (MEPS), Kaiser Family Foundation (KFF)/Health Research Educational Trust (HRET) Employer Health Benefits Survey, American Community Survey (ACS), and National Health Expenditure Accounts (NHEA). STUDY DESIGN: We estimate two dollar amounts for each individual in the synthetic population: (a) payments to finance health care services, which includes all payments by a household and their employers to finance health care, including premiums, out-of-pocket payments, federal and state taxes, and other payments; and (b) the dollar value of health care services received, which equals the amount paid to providers for those services. DATA EXTRACTION METHODS: We linked the nationally representative survey data using statistical matching. We allocated health care expenditures from the NHEA to individuals and households based on expenditures reported in the MEPS. PRINCIPAL FINDINGS: We show that higher-income households pay the most to finance health care in dollar amounts, but the burden of payments as a share of income is greater among lower-income households. CONCLUSIONS: Accounting for all sources of payments provides a clear picture of the burden of financing health care costs, and how that burden is spread under our current financing system.

Expanding Enrollment Without the Individual Mandate: Options to Bring More People into the Individual Market.

Issue: Recent changes to the Affordable Care Act, including elimination of the individual mandate penalty, the halting of federal payments for cost-sharing reductions, and expanded access to short-term plans, may reduce enrollment in the individual market. Goal: Analyze options to increase enrollment, accounting for recent policy changes. Methods: RAND's COMPARE microsimulation model is used to analyze six policies that would expand access to tax credits, increase their generosity, and fund a reinsurance program. Key Findings and Conclusions: The options would increase individual market enrollment by 400,000 to 3.2 million in 2020. Net increases in total enrollment (300,000 to 2.4 million) are smaller because of offsetting decreases in employer-sponsored insurance. The largest gains are possible through two options: large-scale investment in reinsurance, and extension of tax credits to higher-income people combined with increases in the generosity of existing tax credits. If funded through a fee on health plans, reinsurance could be implemented without increasing the federal deficit. Additional taxpayer costs would increase by $1 billion to $23 billion, depending on the policy. While enhanced tax credits for young adults would lead to small coverage gains, they would entail the lowest costs to taxpayers among the six options.

A Comprehensive Assessment of Four Options for Financing Health Care Delivery in Oregon.

This article describes four options for financing health care for residents of the state of Oregon and compares the projected impacts and feasibility of each option. The Single Payer option and the Health Care Ingenuity Plan would achieve universal coverage, while the Public Option would add a state-sponsored plan to the Affordable Care Act (ACA) Marketplace. Under the Status Quo option, Oregon would maintain its expansion of Medicaid and subsidies for nongroup coverage through the ACA Marketplace. The state could cover all residents under the Single Payer option with little change in overall health care costs, but doing so would require cuts to provider payment rates that could worsen access to care, and implementation hurdles may be insurmountable. The Health Care Ingenuity Plan, a state-managed plan featuring competition among private plans, would also achieve universal coverage and would sever the employer-health insurance link, but the provider payment rates would likely be set too high, so health care costs would increase. The Public Option would be the easiest of the three options to implement, but because it would not affect many people, it would be an incremental improvement to the Status Quo. Policymakers will need to weigh these options against their desire for change to balance the benefits with the trade-offs.

Extending Marketplace Tax Credits Would Make Coverage More Affordable for Middle-Income Adults.

ISSUE: Affordability of health coverage is a growing challenge for Americans facing rising premiums, deductibles, and copayments. The Affordable Care Act's tax credits make marketplace insurance more affordable for eligible lower-income individuals. However, individuals lose tax credits when their income exceeds 400 percent of the federal poverty level, creating a steep cliff. GOALS: To analyze the effects of extending eligibility for tax credits to individuals with incomes above 400 percent of the federal poverty level. METHODS: We used RAND's COMPARE microsimulation model to examine changes in insurance coverage and health care spending. KEY FINDINGS AND CONCLUSIONS: Extending tax-credit eligibility increases insurance enrollment by 1.2 million, at a total federal cost of $6.0 billion. Those who would benefit from the tax-credit extension are mostly middle-income adults ages 50 to 64. These new enrollees would be healthier than current enrollees their age, which would improve the risk pool and lower premiums. Eliminating the cliff at 400 percent of the federal poverty level is one policy option that may be considered to increase affordability of insurance.

What is Single-Payer Health Care? A Review of Definitions and Proposals in the U.S.

BACKGROUND: Single-payer systems have been proposed as a health care reform alternative in the United States. However, there is no consensus on the definition of single-payer. Most definitions characterize single-payer as one entity that collects funds and pays for health care on behalf on an entire population. Increased flexibility for state health care reform may provide opportunities for state-based single-payer systems to be considered. OBJECTIVE: To explore the concept of single-payer and to describe the contents of single-payer health care proposals. DESIGN: We compared single-payer definitions and proposals. We coded the proposal text for provisions that would change how the health care system functions and could impact health care access, quality, and cost. MAIN MEASURES: The share of proposals that include changes to the financing, pooling, purchasing, and delivery of health care; and possible impact on access, quality, and costs. KEY RESULTS: We identified 25 proposals for national or state single-payer plans from journal and legislative databases. The proposals typically call for wide-ranging reform; nearly all include changes across the financing, pooling, purchasing, and delivery of health care services. Many provisions aiming to improve access, quality, and cost containment are also included, but the proposals vary in how they plan to achieve these improvements. Common provisions are related to comprehensive benefits, patient choice of providers, little or no cost sharing, the role of private insurance, provider guidelines and standards, periodic reviews of the benefits package, electronic medical records and billing, prescription drug formulary, global budgets, administrative cost thresholds, payment reform and studies, and the authority to implement cost-containment strategies. CONCLUSIONS: Single-payer systems are heterogeneous. Acknowledgment of what is considered as single-payer and the characteristics that are variable is important for nuanced policy discussions on specific reform proposals.

The Medicare Access And CHIP Reauthorization Act: Effects On Medicare Payment Policy And Spending.

In 2015, Congress repealed the Sustainable Growth Rate formula for Medicare physician payment, eliminating mandatory payment cuts when spending exceeded what was budgeted. In its place, Congress enacted the Medicare Access and CHIP Reauthorization Act (MACRA), which established a two-track performance-based payment system that encourages physicians to participate in alternative payment models. MACRA could have huge effects on health care delivery, but the nature of those effects is highly uncertain. Using the RAND Corporation's Health Care Payment and Delivery Simulation Model, we estimated the effects of MACRA on Medicare spending and utilization and examined how effects would differ under various scenarios. We estimate that MACRA will decrease Medicare spending on physician services by -$35 to -$106 billion (-2.3 percent to -7.1 percent) and change spending on hospital services by $32 to -$250 billion (0.7 percent to -5.1 percent) in 2015-30. The spending effects are critically dependent on the strength of incentives in the alternative payment models, particularly the incentives for physicians to reduce hospital spending and physician responses to MACRA payment rates.

The Economic Incidence of Health Care Spending in Vermont.

In 2015, Vermont legislators may consider financing plans to implement Act 48, a law that aims to provide universal health care coverage to all Vermont residents starting in 2017. In this analysis, we estimate the economic incidence of payments for health care by Vermont residents and the value of health care benefits received by Vermont residents in 2012 and 2017, without the implementation of Act 48 reforms. The goal of the analysis was to understand how health care is currently paid for in Vermont, and to provide a baseline for understanding the possible effects of Act 48. We use data from the 2012 Vermont Household Health Interview Survey, the Vermont Health Care Uniform Evaluation and Reporting System, and administrative data on taxes to estimate payments in 2012. We then project these estimates forward to 2017, using the RAND COMPARE microsimulation to account for how health care coverage in Vermont will change as a result of the Affordable Care Act (ACA). We find that most Vermont residents receive more in health benefits than they pay for directly or through taxes. While lower-income individuals, on average, pay less than higher-income individuals, there is considerable variation across individuals in the level of payment for health care. Much of the current variation stems from the fractured nature of the health system, with some individuals receiving coverage through employers, some through the Exchange (i.e., the health insurance marketplace created by the ACA), and some through other sources. As Vermont considers health care reform, legislators may wish to consider options to reduce the degree of variation in payments made by individuals with similar income levels.

Specialty Payment Model Opportunities and Assessment: Gastroenterology and Cardiology Model Design Report.

Gastroenterology and cardiology services are common and costly among Medicare beneficiaries. Episode-based payment, which aims to create incentives for high-quality, low-cost care, has been identified as a promising alternative payment model. This article describes research related to the design of episode-based payment models for ambulatory gastroenterology and cardiology services for possible testing by the Center for Medicare and Medicaid Innovation at the Centers for Medicare and Medicaid Services (CMS). The authors analyzed Medicare claims data to describe the frequency and characteristics of gastroenterology and cardiology index procedures, the practices that delivered index procedures, and the patients that received index procedures. The results of these analyses can help inform CMS decisions about the definition of episodes in an episode-based payment model; payment adjustments for service setting, multiple procedures, or other factors; and eligibility for the payment model.

Specialty Payment Model Opportunities and Assessment: Oncology Model Design Report.

This article describes research related to the design of a payment model for specialty oncology services for possible testing by the Center for Medicare and Medicaid Innovation at the Centers for Medicare & Medicaid Services (CMS). Cancer is a common and costly condition. Episode-based payment, which aims to create incentives for high-quality, low-cost care, has been identified as a promising alternative payment model for oncology care. Episode-based payment systems can provide flexibility to health care providers to select among the most effective and efficient treatment alternatives, including activities that are not currently reimbursed under Medicare payment policies. However, the model design also needs to ensure that high-quality care is delivered and that beneficial treatments are not withheld from patients. CMS asked MITRE and RAND to conduct analyses to inform design decisions related to an episode-based oncology model for Medicare beneficiaries undergoing chemotherapy treatment for cancer. In particular, this study focuses on analyses of Medicare claims data related to the definition of the initiation of an episode of chemotherapy, patterns of spending during and surrounding episodes of chemotherapy, and attribution of episodes of chemotherapy to physician practices. We found that the time between the primary cancer diagnosis and chemotherapy initiation varied widely across patients, ranging from one day to over seven years, with a median of 2.4 months. The average level of total monthly payments varied considerably across cancers, with the highest spending peak of $9,972 for lymphoma, and peaks of $3,109 for breast cancer and $2,135 for prostate cancer.

Vitamin D and Calcium: A Systematic Review of Health Outcomes (Update).

BACKGROUND: In 2009, the Institute of Medicine/Food and Nutrition Board constituted a Dietary Reference Intakes (DRI) committee to undertake a review of the evidence that had emerged (since the 1997 DRI report) on the relationship of vitamin D and calcium, both individually and combined, to a wide range of health outcomes, and potential revision of the DRI values for these nutrients. To support that review, several United States and Canadian Federal Government agencies commissioned a systematic review of the scientific literature for use during the deliberations by the committee. The intent was to support a transparent literature review process and provide a foundation for subsequent reviews of the nutrients. The committee used the resulting literature review in their revision of the DRIs.In 2013, in preparation for a project the National Institutes of Health Office of Dietary Supplements (NIH/ODS) was undertaking related to evidence-based decisionmaking for vitamin D in primary care, based on the updated DRI report, the ODS and AHRQ requested an update to the 2009 systematic review to incorporate the findings of studies conducted since the 2009 evidence review on the relationship between vitamin D alone or vitamin D plus calcium to selected health outcomes and to report on the methods used to assay vitamin D in the included trials. PURPOSE: To systematically summarize the evidence on the relationship between vitamin D alone or in combination with calcium on selected health outcomes included in the earlier review: primarily those related to bone health, cardiovascular health, cancer, immune function, pregnancy, all-cause mortality, and vitamin D status; and to identify the vitamin D assay methods and procedures used for the interventional studies that aimed to assess the effect of vitamin D administration on serum 25(OH)D concentrations, and to stratify key outcomes by methods used to assay serum 25(OH)D concentrations. DATA SOURCES: MEDLINE; Cochrane Central; Cochrane Database of Systematic Reviews; and the Health Technology Assessments; search limited to English-language articles on humans. STUDY SELECTION: Primary interventional or prospective observational studies that reported outcomes of interest in human subjects in relation to vitamin D alone or in combination with calcium, as well as systematic reviews that met the inclusion and exclusion criteria. DATA EXTRACTION: A standardized protocol with predefined criteria was used to extract details on study design, interventions, outcomes, and study quality. DATA SYNTHESIS: We summarized 154 newly identified primary articles and two new systematic reviews that incorporated more than 93 additional primary articles. Available evidence focused mainly on bone health, cardiovascular diseases, or cancer outcomes. Findings were inconsistent across studies for bone health; breast, colorectal, and prostate cancer; cardiovascular disease and mortality; immune function; and pregnancy-related outcomes. Few studies assessed pancreatic cancer and birth outcomes. One new systematic review of observational studies found that circulating 25(OH)D was generally inversely associated with risk for cardiovascular disease. Methods used to assay serum 25(OH)D in studies reporting on key outcomes diverged widely. The current report also identified one new systematic review published since the original report that addressed whether a dose response relationship exists between dietary and supplemental vitamin D intake and serum 25(OH)D concentrations. The systematic review, based on 76 RCTs, reported widely varying increases in serum concentrations of 25(OH)D for similar doses of vitamin D, with a general increase in serum concentration with dietary intake. The RCTs identified for the current report found increases in serum 25(OH)D with supplementation; however, the findings varied by age group and health status of participants, baseline vitamin D status, dose, duration, and assay used to assess serum 25(OH)D. LIMITATIONS: Studies on vitamin D and calcium were not specifically targeted at life stages (except for pregnant and postmenopausal women) specified for the determination of DRI and were often underpowered for their intended outcomes. Studies vary widely in methodological quality and in the assays used to measure vitamin D status. CONCLUSIONS: In solid agreement with the findings of the original report, the majority of the findings concerning vitamin D, alone or in combination with calcium, on the health outcomes of interest were inconsistent. Associations observed in prospective cohort and nested case-control studies were inconsistent, or when consistent, were rarely supported by the results of randomized controlled trials. Clear dose-response relationships between intakes of vitamin D and health outcomes were rarely observed. Although a large number of new studies (and longer followups to older studies) were identified, particularly for cardiovascular outcomes, all-cause mortality, several types of cancer, and intermediate outcomes for bone health, no firm conclusions can be drawn. Studies identified for the current report suggest a possible U-shaped association between serum 25(OH)D concentrations and both all-cause mortality and hypertension and also suggest that the level of supplemental vitamin D and calcium administered in the Women's Health Initiative Calcium-Vitamin D Trial are not associated with an increased risk for cardiovascular disease or cancer among postmenopausal women who are not taking additional supplemental vitamin D and calcium. Studies suggest the method used to assay 25(OH)D may influence the outcomes of dose-response assessments. Beyond these observations, it is difficult to make any substantive statements on the basis of the available evidence concerning the association of either serum 25(OH)D concentration, vitamin D supplementation, calcium intake, or the combination of both nutrients, with the various health outcomes because most of the findings were inconsistent.
