The U.S. healthcare delivery system has developed through a ✓ Solved

The U.S. healthcare delivery system has developed through a long history of legislation that aimed to expand access, stabilize financing, and improve the quality of care. As Shi and Singh (2022) explain, the system functions as a loosely coordinated patchwork that has evolved through major policy milestones rather than through a single integrated plan. This post evaluates three legislative acts that significantly influenced cost, quality, access, and the shift toward value-based care: the Social Security Amendments of 1965, the Patient Protection and Affordable Care Act (PPACA) of 2010, and the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015. Prior to 1965, health insurance coverage was tied mainly to employment, which left older adults, people with disabilities, and many low-income families uninsured.

Rising costs, high levels of poverty among older adults, and limited access to hospitals and physicians created a significant need for reform (Shi & Singh, 2022). According to the Centers for Medicare & Medicaid Services (2021), Medicare and Medicaid were enacted to address gaps in access and reduce financial barriers. These programs expanded coverage to millions who previously relied on inconsistent charity care and public hospitals. The Social Security Amendments improved access immediately, but they were built on fee-for-service payment structures that emphasized volume over value. Shi and Singh (2022) note that while the legislation expanded access, it did not initially address rising costs or quality variations.

Over time, however, Medicare and Medicaid provided the federal platform that allowed future value-based reforms to develop. The Commonwealth Fund (n.d.) highlights that these programs eventually became central to the introduction of accountable care organizations (ACOs) and alternative payment models, which are now key components of value-based care. By 2010, the United States faced a high uninsured rate, inconsistent quality of care, and rapidly rising healthcare costs. Many individuals were denied coverage due to preexisting conditions, and millions lacked affordable insurance options. Shi and Singh (2022) explain that the ACA was created in response to these access and affordability challenges.

The legislation expanded Medicaid eligibility, created subsidized insurance marketplaces, and implemented consumer protections. The ACA also directly promoted value-based care. The Commonwealth Fund (n.d.) reports that the ACA established ACOs, bundled payments, the Hospital Value-Based Purchasing Program, and penalties for excess readmissions. These initiatives tied provider reimbursement to quality and outcomes rather than service volume. KFF (n.d.) further notes that ACA reforms led to increased preventive service use and reduced financial barriers to care.

Because of these changes, administrators were incentivized to focus on care coordination, population health, and reducing hospital-acquired conditions. Before MACRA, Medicare physician payment was governed by the Sustainable Growth Rate (SGR) formula, which repeatedly threatened significant payment cuts and increased uncertainty for providers (Shi & Singh, 2022). MACRA eliminated the SGR and replaced fragmented reporting systems with the Quality Payment Program (QPP). The QPP includes the Merit-based Incentive Payment System (MIPS) and Advanced Alternative Payment Models (APMs). CMS (2021) explains that these models tie clinicians’ Medicare payments directly to quality, cost, and data reporting requirements.

MACRA significantly advanced the value-based care movement. The Federal Register (n.d.) notes that APMs encourage providers to assume financial and clinical accountability for patient outcomes. Participation in risk-bearing models rewards organizations that invest in care coordination, health information technology, and preventive care. Although early evaluations indicate mixed results and increased administrative burden, MACRA continues to reinforce the expectation that clinicians must participate in some form of value-driven reimbursement (Shi & Singh, 2022). These three legislative acts collectively reveal how U.S. health policy transitioned from basic access expansion to full-scale value-based reform. - The Social Security Amendments of 1965 expanded access dramatically but did not control cost or quality initially.

They created the national infrastructure for later reforms (Shi & Singh, 2022; CMS, 2021). - The ACA addressed high uninsurance rates and rising costs while embedding value-based models into Medicare and Medicaid (Commonwealth Fund, n.d.; KFF, n.d.). - MACRA transformed physician payment and accelerated the adoption of alternative payment models tied to outcomes (CMS, 2021; Federal Register, n.d.). Overall, these acts shifted healthcare delivery toward improved access, greater accountability, and payment structures that emphasize outcomes and population health. For healthcare administrators, these policies continue to shape organizational strategy by promoting investments in quality improvement, data analytics, care coordination, and programs that support long-term value-based performance.

Colleague 2 Asharia Golding Historical Developments in Healthcare Delivery and Value-Based Care Healthcare delivery in the United States has evolved through a series of significant legislative milestones that sought to remedy gaps in access, control rising costs, and improve quality. Each landmark statute emerged from distinct historical pressures and produced downstream effects that reshaped the organization, financing, and incentives of the health system. This discussion examines three pivotal laws—the Social Security Amendments of 1965 (establishing Medicare and Medicaid), the Patient Protection and Affordable Care Act (2010; ACA), and the Medicare Access and CHIP Reauthorization Act (2015; MACRA)—and evaluates their historical context and impact across cost, quality, access, and the shift toward value-based care.

Social Security Amendments of 1965 (Medicare and Medicaid) Historical circumstances and need By the early 1960s, a growing public concern had focused on the inability of many elderly and low-income Americans to afford healthcare. Before 1965, a substantial portion of older Americans lacked insurance and faced catastrophic medical costs; private market coverage was uneven, and many hospitals and physicians were financially inaccessible to the poor and elderly (Berkowitz, 2005). Political momentum—shaped by the advocacy of presidents, social reformers, and demographic changes such as increased longevity—made national health insurance for the elderly and for low-income families a pressing public policy agenda culminating in the Social Security Amendments of 1965 (National Archives, 2022).

Effects on cost, quality, and access The Medicare and Medicaid programs substantially expanded access. Medicare provided near-universal hospital and physician insurance for those aged 65 and older, and Medicaid provided federal-state matching funds for poor and disabled populations. Access improved dramatically; hospital utilization among the elderly increased, and previously uninsured populations gained access to care (CMS, 2022). Cost effects were complex: federal healthcare expenditure rose sharply as coverage expanded, contributing to growth in national healthcare spending, while out-of-pocket spending for beneficiaries fell relative to pre-1965 levels (Berkowitz, 2005). Quality considerations included the enforcement of civil rights and hospital standards.

Medicare's financing incentives encouraged hospital modernization and contributed to the desegregation of hospitals, as federal funds were conditioned on nondiscriminatory practices (Medicare Rights, 2025). Reported implications and influence on value-based delivery The 1965 programs established a dominant federal purchaser whose payment policies significantly influenced provider behavior for decades. Initially, the programs reinforced fee-for-service incentives and stimulated increased service volume and institutional capacity (for example, hospital expansions and more physician training). Over time, however, Medicare's size and data flows created the administrative capacity and policy leverage necessary to test alternative payment models that would later become the core of value-based efforts (Shi & Singh, 2022; CMS, 2022).

Thus, while Medicare/Medicaid of 1965 did not itself establish value-based payment, it established the federal platform and scale required for later reforms that link payment to quality and cost efficiency. Patient Protection and Affordable Care Act (2010; ACA) Historical circumstances and need By the late 2000s, the U.S. faced a persistent uninsured population, rising employer and household premiums, and growing concern about the sustainability of healthcare spending and poor health outcomes compared with other high-income countries. The 2008 financial crisis also heightened attention to healthcare costs and the instability of coverage. The political consensus around expanding insurance access and restraining cost growth culminated in the passage of the ACA in 2010, which sought comprehensive reform addressing coverage, consumer protections, and new payment and delivery incentives (Blumenthal & Collins, 2015).

Effects on cost, quality, and access The ACA had its most apparent effects on access, as millions of Americans gained insurance through Medicaid expansion in participating states and through subsidized individual market exchanges. The ACA also substantially reduced the uninsured rate (Glied et al., 2017; NEJM analyses). Access to primary and preventive services improved for newly insured populations, and financial barriers to care were reduced for many (Commonwealth Fund, 2017). Effects on cost were mixed: the ACA included multiple cost-containment elements (Medicare payment reforms, payment demonstration projects, emphasis on preventive care), and slowed the historical growth rate of national health expenditures in some years, but the long-term impact on aggregate spending has been modest and contested (Feldman, 2015).

Quality initiatives embedded in the ACA—such as expanded support for patient-centered medical homes, Accountable Care Organizations (ACOs), and CMS value-based programs—motivated measurement and reporting on quality, but heterogeneity in results persisted across programs and settings (McDonough, 2015; Annual Reviews, 2020). Reported implications and influence on value-based delivery Significantly, the ACA accelerated federal commitment to value-based delivery. The law explicitly authorized and funded models that tied payment to outcomes (e.g., the Center for Medicare and Medicaid Innovation), incentivized care coordination through ACOs, and pushed providers toward alternative payment models. The ACA thus shifted policy emphasis from simply expanding coverage to experimenting with payment reform and delivery redesign aimed at "better care, smarter spending" (NEJM, 2019).

Implementation challenges—measurement complexity, provider administrative burden, and uneven uptake across regions—limited immediate transformative effects, but the ACA institutionalized mechanisms (data infrastructure, demonstration authority, quality metrics) are central to the ongoing transition toward value-based care (Commonwealth Fund; Annual Reviews, 2020). Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 Historical circumstances and need MACRA emerged from longstanding dissatisfaction with physician payment under Medicare's Sustainable Growth Rate (SGR) formula, which created instability and frequent temporary "doc fixes." Policymakers sought a permanent solution that would realign incentives toward performance and value rather than volume.

In 2015, Congress passed MACRA to replace the SGR and to provide a new framework—the Quality Payment Program (QPP)—that rewards clinicians for high-quality and cost-efficient care through two tracks: the Merit-based Incentive Payment System (MIPS) and Advanced Alternative Payment Models (APMs) (CMS, 2024). Effects on cost, quality, and access MACRA's direct objective was to change clinician payment incentives to promote quality and cost control. The QPP emphasized performance measurement, reporting, and participation in APMs that assume financial risk tied to outcomes. Evidence to date shows mixed effects: MACRA accelerated measurement and nudged many clinicians toward reporting quality metrics, but administrative burden and program complexity have been critiqued; early evaluations find modest associations with improved process measures but limited evidence of broad, sustained improvements in population health or cost reductions in the short term (Cheng et al., 2020; Paragon Institute critique).

Access impacts are indirect: by incentivizing care coordination and APM participation, MACRA can support the system's capacity to manage populations; however, concerns remain about provider consolidation and potential access implications in underserved areas if risk-bearing models deter smaller providers. Reported implications and influence on value-based delivery MACRA represents a formal shift within Medicare from volume-based payments to a value-based payment approach. By creating MIPS and APM pathways, MACRA aimed to scale up alternative payment models and encourage clinicians to accept accountability for cost and quality. However, program design—characterized by the complexity of measures, risk adjustment concerns, and the voluntary nature of APM participation—has limited the speed and uniformity of the transition (Cheng et al., 2020; Annual Reviews, 2020).

Nonetheless, MACRA institutionalized the concept that clinician payment should be tied to performance and contributed to the proliferation of value-based payment approaches, including bundled payments, shared-savings ACO models, and population-based contracts. Comparative analysis across the three acts: cost, quality, access, and value Each statute addressed a distinct problem set yet collectively contributed to the health system's shift toward value. The 1965 amendments prioritized access for vulnerable populations, creating a large federal payer and dramatically expanding demand for services; this expansion increased public expenditures but laid the administrative and data groundwork for future payment experimentation (Berkowitz, 2005; CMS, 2022).

The ACA (2010) targeted gaps in access and introduced policies and infrastructure to facilitate delivery reform and payment innovation, achieving meaningful gains in insurance coverage and embedding explicit mechanisms to test value-based models (Blumenthal & Collins, 2015; Commonwealth Fund, 2017). MACRA (2015) sought to "operationalize" the payment side of value by directly changing clinician reimbursement toward measured performance and alternative payment models, thereby attempting to realign provider incentives (CMS, 2024; Cheng et al., 2020). In terms of cost, the 1965 programs increased federal health spending while reducing individual financial burden; the ACA moderated uninsured rates and introduced modest cost-saving mechanisms but did not eliminate spending growth pressures; MACRA focused on cost containment through value incentives but has, so far, shown modest systemic savings and variable impact across measures.

Quality improvements have generally followed from greater measurement and reporting (ACA, MACRA) and from increased access to necessary care (Medicare/Medicaid); however, translating process gains into consistent outcome and population health improvements have proven difficult and uneven. Access improved most dramatically from the 1965 programs and from the ACA's coverage expansions; MACRA's effects on access are indirect and depend on whether value-based payment models are designed and implemented in ways that preserve or expand provider participation in underserved areas. Evaluation and implications for current value-based transformation Taken together, these three laws represent a trajectory from the expansion of coverage (1965) to comprehensive coverage reform and infrastructure for delivery reform (ACA) to explicit payment redesign for clinicians (MACRA).

The federal government's evolving role—from payer of last resort to active architect of payment innovations—has been central to the shift toward value. However, persistent challenges remain measurement complexity and administrative burden, misaligned incentives across payers, incomplete risk adjustment, provider consolidation and market power, and uneven state-level adoption (Annual Reviews, 2020; Paragon Institute, 2022). For value-based care to realize its full potential, policy must continue to refine outcome-focused measures, reduce the reporting burden, align incentives across public and private payers, and foster support for smaller and rural providers to participate in APMs. References: Annual Reviews.
