Creating an effective and efficient publicly sponsored health care delivery system

An effective and efficient publicly sponsored health care delivery system can increase access to care, improve health care outcomes, and reduce spending. A publicly sponsored health care delivery system can be created by integrating services that are already federally subsidized: community health centers (CHCs), public and safety-net hospitals, and residency training programs. The Patient Protection and Affordable Care Act includes measures that support primary care generally and CHCs in particular. A publicly sponsored health care delivery system combining primary care based in CHCs with safety-net hospitals and the specialists that serve them could also benefit from incentives in the Patient Protection and Affordable Care Act for the creation of accountable care organizations, and reimbursement based on quality and cost control.     

Insurance coverage and access: implications for health policy.

Data are presented from a recent survey of the United States population comparing the characteristics and levels of access to medical care of persons under 65 years who have group or individual private health insurance, public health insurance, or no third-party coverage. The uninsured group appeared to fall between the privately insured and publicly insured groups on measures of social and economic status. Persons with publicly subsidized forms of insurance coverage utilized services at the highest rates, and uninsured persons used them at the lowest rates. Neither of these groups was as satisfied with the convenience or the quality of the care it obtained as the privately insured group. Implications of these findings for national health insurance and other health policy initiatives are discussed.     

Local access to care programs (LACPs): new developments in the access to care for the uninsured

Context: New, locally based health care access programs are emerging in response to the growing number of uninsured, providing an alternative to health insurance and traditional safety net providers. Although these programs have been largely overlooked in health services research and health policy, they are becoming an important local supplement to the historically overburdened safety net. Methods: This article is based on a literature review, Internet search, and key actor interviews to document programs in the United States, using a typology to classify the programs and document key characteristics. Findings: Local access to care programs (LACPs) fall outside traditional private and publicly subsidized insurance programs. They have a formal enrollment process, eligibility determination, and enrollment fees that give enrollees access to a network of providers that have agreed to offer free or reduced‐price health care services. The forty‐seven LACPs documented in this article were categorized into four general models: three‐share programs, national‐provider networks, county‐based indigent care, and local provider–based programs. Conclusions: New, locally based health access programs are being developed to meet the health care needs of the growing number of uninsured adults. These programs offer an alternative to traditional health insurance and build on the tradition of county‐based care for the indigent. It is important that these locally based, alternative paths to health care services be documented and monitored, as the number of uninsured adults is continuing to grow and these programs are becoming a larger component of the U.S. health care safety net.     

Type of health insurance and the quality of primary care experience

OBJECTIVES: This study examined the association between type of health insurance coverage and quality of primary care as measured by its distinguishing attributes--first contact, longitudinality, comprehensiveness, and coordination. METHODS: The household component of the 1996 Medical Expenditure Panel Survey was used for this study. The analysis primarily focused on subjects aged younger than 65 years who identified a usual source of care. Logistic regressions were used to examine the independent effects of insurance status on primary care attributes while individual sociodemographic characteristics were controlled for. RESULTS: The experience of primary care varies according to insurance status. The insured are able to obtain better primary care than the uninsured, and the privately insured are able to obtain better primary care than the publicly insured. Those insured through fee-for-service coverage experience better longitudinal care and less of a barrier to access than those insured through health maintenance organizations (HMOs). CONCLUSIONS: While expanding insurance coverage is important for establishing access to care, efforts are needed to enhance the quality of primary health care, particularly for the publicly insured. Policymakers should closely monitor the quality of primary care provided by HMOs.     

Limits to the safety net: teaching hospital faculty report on their patients' access to care

Many major teaching hospitals might not be able to offer adequate access to specialty care for uninsured patients. This study found that medical school faculty were more likely to have difficulty obtaining specialty services for uninsured than for privately insured patients. These gaps in access were similar in magnitude for public and private institutions. Initial treatment of uninsured patients at academic health centers (AHCs) does not guarantee access to specialty and other referral services, which suggests that there are limits to relying on a health care safety net for uninsured patients. AHCs and affiliated group practices should examine policies that limit access for uninsured patients.     

Availability of safety net providers and access to care of uninsured persons

OBJECTIVE: To understand how proximity to safety net clinics and hospitals affects a variety of measures of access to care and service use by uninsured persons. DATA SOURCES: The 1998-1999 Community Tracking Study household survey, administered primarily by telephone survey to households in 60 randomly selected communities, linked to data on community health centers, other free clinics, and safety net hospitals. STUDY DESIGN: Instrumental variable estimation of multivariate regression models of several measures of access to care (having a usual source of care, unmet or delayed medical care needs, ambulatory service use, and overnight hospital stays) against endogenous measures of distances to the nearest community health center and safety net hospital, controlling for characteristics of uninsured persons and other area characteristics that are related to access to care. The models are estimated with data from a nationally representative sample of uninsured people. PRINCIPAL FINDINGS: Shorter distances to the nearest safety net providers increase access to care for uninsured persons. Failure to account for the endogeneity of distance to safety net providers on access to care generally leads to finding little or no safety net effects on access. CONCLUSIONS: Closer proximity to the safety net increases access to care for uninsured persons. However, the improvements in access to care are relatively small compared with similar measures of access to care for insured persons. Modest expansion of the safety net is unlikely to provide a full substitute for insurance coverage expansions.     

Effects of changes in incomes and practice circumstances on physicians' decisions to treat charity and Medicaid patients

CONTEXT: The decline over the past decade in the percentage of physicians providing care to charity and Medicaid patients has been attributed to both financial pressure and the changing practice environment. Policymakers should be concerned about these trends, since private physicians are a major source of medical care for low-income persons. This study examines how changes in physicians' practice income, ownership, and size affect their decisions to stop or start treating charity care and Medicaid patients. METHODS: This study uses panel data from four rounds of the Community Tracking Study Physician Survey. The dependent variables are the likelihood of physicians' (1) dropping charity care, (2) starting to provide charity care, (3) no longer accepting new Medicaid patients, and (4) starting to accept new Medicaid patients. The primary independent variables are changes in physicians' practice income, ownership, and practice type/size. Multivariate analysis controls for the effects of other physician practice characteristics, health policies, and health care market factors. FINDINGS: A decline in physicians' income increased the likelihood that a physician would stop accepting new Medicaid patients but had no effect on his or her decision to provide charity care. Those physicians who switched from being owners to employees or from small to larger practices were more likely to drop charity care and to start accepting Medicaid patients, and physicians who made the opposite practice changes did the reverse. CONCLUSIONS: Changes in their income and practice arrangements make physicians less willing to accept Medicaid and uninsured patients. Moreover, physicians moving into different practice arrangements treat charity and Medicaid patients as substitutes rather than as similar types of patients. To reverse these trends, policymakers should consider raising Medicaid reimbursement rates and subsidizing organizations that encourage private physicians to provide charity care.     

Public or private providers? U.S. women's use of reproductive health services

CONTEXT: U.S. women receive contraceptive and reproductive health services from a wide range of publicly funded and private providers. Information on trends in and on patterns of service use can help policymakers and program planners assess the adequacy of current services and plan for future improvements. METHODS: Women who reported in the 1995 National Survey of Family Growth that they had obtained any contraceptive or other reproductive health service in the past year were classified by their primary source of care, and the services they received, their characteristics and their primary source of care were analyzed. Logistic regression was used to test which factors predict women's use of publicly subsidized family planning clinics and of specific types of services. RESULTS: The percentage of women of reproductive age who obtained family planning services increased slightly between 1988 and 1995, primarily among women aged 30 and older. Nearly one in four women who received any contraceptive care visited a publicly funded family planning clinic, as did one in three who received contraceptive counseling or sexually transmitted disease (STD) testing and treatment. Women whose primary source of reproductive care was a publicly funded family planning clinic received a wider range of services than women who visited private providers; moreover, the former were significantly more likely to report obtaining contraceptive care or STD-related care, even after the effects of their background characteristics were controlled. Young, unmarried, minority, less-educated and poor women were more likely than others to depend on publicly subsidized family planning clinics. Source of health insurance was one of the most important predictors of the use of public family planning clinics: Medicaid recipients and uninsured women were 3-4 times as likely as women with private insurance to obtain clinic care. CONCLUSIONS: Publicly funded family planning clinics are an important source of contraceptive and other reproductive health care, providing millions of U.S. women with a wide range of services. Since women's need for reproductive care and for publicly subsidized care is not likely to diminish, clinics may be financially challenged in their efforts to continue delivering this broad package of services to growing numbers of uninsured or disenfranchised women.     

The Resilience of the Health Care Safety Net, 1996–2001

Objective .  To determine how the capacity and viability of local health care safety nets changed over the last six years and to draw lessons from these changes.
Data Source .  The first three rounds (May 1996 to March 2001) of Community Tracking Study site visits to 12 communities.
Study Design .  Researchers visited the study communities every two years to interview leaders of local health care systems about changes in the organization, delivery, and financing of health care and the impact of these changes on people. For this analysis, we collected data on safety net capacity and viability through interviews with public and not-for-profit hospitals, community health centers, health departments, government officials, consumer advocates, academics, and others. We asked about the effects of market and policy changes on the safety net and how the safety net responded, as well as the impact of these changes on care for the low-income uninsured.
Principal Findings .  The safety net in three-quarters of the communities was stable or improved by the end of the study period, leading to improved access to primary and preventive care for the low-income uninsured. Policy responses to pressures such as the Balanced Budget Act and Medicaid managed care, along with effective safety net strategies and supportive conditions, helped reinforce the safety net. However, the safety net in three sites deteriorated and access to specialty services remained inadequate across the 12 sites.
Conclusions.  Despite pessimistic predictions and some notable exceptions, the health care safety net grew stronger over the past six years. Given considerable community variation, however, this analysis indicates that policymakers can apply a number of lessons from strong and improving safety nets to strengthen those that are weaker, particularly as the current economy poses new challenges.     

Health reform holds both risks and rewards for safety-net providers and racially and ethnically diverse patients

The Affordable Care Act of 2010 creates both opportunities and risks for safety-net providers in caring for low-income, diverse patients. New funding for health centers; support for coordinated, patient-centered care; and expansion of the primary care workforce are some of the opportunities that potentially strengthen the safety net. However, declining payments to safety-net hospitals, existing financial hardships, and shifts in the health care marketplace may intensify competition, thwart the ability to innovate, and endanger the financial viability of safety-net providers. Support of state and local governments, as well as philanthropies, will be crucial to helping safety-net providers transition to the new health care environment and to preventing the unintended erosion of the safety net for racially and ethnically diverse populations.     

Private health care in Canada: savior or siren?

In canada, health care is publicly insured and available to all at no charge. Recently, financial pressures have threatened the system and led to considerable debate about how to save it. One proposal is to permit privately funded health care alongside the public system, resulting in what is popularly called a two-tiered system. This paper presents some of the arguments for and against two-tiered health care. Using as an example cataract surgery-a procedure that is available both publicly and privately-the authors look at some common beliefs about private health care in Canada. They conclude that the growth in private sector cataract surgery does not appear to be related to cutbacks or rationing, that private access does not necessarily shorten waiting times, and that, contrary to popular belief, it is not only the well-to-do who pay for private surgery in Canada.     

The contribution of insurance coverage and community resources to reducing racial/ethnic disparities in access to care

OBJECTIVE: To examine the extent to which health insurance coverage and available safety net resources reduced racial and ethnic disparities in access to care. DATA SOURCES: Nationally representative sample of 11,692 African American, 10,325 Hispanic, and 74,397 white persons. Nonelderly persons with public or private health insurance and those who were uninsured. STUDY DESIGN: Two cross-sectional surveys of households conducted during 1996-1997 and 1998-1999. DATA COLLECTION: Commonly used measures of access to and utilization of medical care were constructed for individuals. These measures include the following. (1) percent reporting unmet medical needs, (2) percent without a regular health care provider, and (3) no visit with a physician in the past year. FINDINGS: More than 6.5 percent of Hispanic and African Americans reported having unmet medical needs compared to less than 5.6 percent of white Americans. Hispanics were least likely to see the same doctor at their usual source of care (59 percent), compared to African Americans (66 percent) and whites (75 percent). Similarly, Hispanics were less likely than either African Americans or whites to have seen a doctor in the last year (65 percent compared to 76 percent or 79 percent). For Hispanics, more than 80 percent of the difference from whites was due to differences in measured characteristics (e.g., insurance coverage, income, and available safety net services). Differences in measured characteristics between African Americans and whites explained less than 80 percent of the access disparities. CONCLUSION: Lack of health insurance was the single most important factor in white-Hispanic differences for all three measures and for two of the white-African American differences. Income differences were the second most important factor, with one exception. Community characteristics generally were much less important, with one exception. The positive effects of insurance coverage in reducing disparities outweigh benefits of increasing physician charity care or access to emergency rooms.     

Safety-Net Providers In Some US Communities Have Increasingly Embraced Coordinated Care Models

Safety-net organizations, which provide health services to uninsured and low-income people, increasingly are looking for ways to coordinate services among providers to improve access to and quality of care and to reduce costs. In this analysis, a part of the Community Tracking Study, we examined trends in safety-net coordination activities from 2000 to 2010 within twelve communities in the United States and found a notable increase in such activities. Six of the twelve communities had made formal efforts to link uninsured people to medical homes and coordinate care with specialists in 2010, compared to only two communities in 2000. We also identified key attributes of safety-net coordinated care systems, such as reliance on a medical home for meeting patients' primary care needs, and lingering challenges to safety-net integration, such as competition among hospitals and community health centers for Medicaid patients.     

Strained local and state government finances among current realities that threaten public hospitals' profitability

This study demonstrates that some safety-net hospitals-those that provide a large share of the care to low-income, uninsured, and Medicaid populations-survived and even thrived before the recent recession. We analyzed the financial performance and governance of 150 hospitals during 2003-07. We found, counterintuitively, that those directly governed by elected officials and in highly competitive markets were more profitable than other safety-net hospitals. They were financially healthy primarily because they obtained subsidies from state and local governments, such as property tax transfers or supplemental Medicaid payments, including disproportionate share payments. However, safety-net hospitals now face a new market reality. The economic downturn, slow recovery, and politics of deficit reduction have eroded the ability of local governments to support the safety net. Many safety-net hospitals have not focused on effective management, cost control, quality improvement, or services that attract insured patients. As a result, and coupled with new uncertainties regarding Medicaid expansion stemming from the recent Supreme Court decision on the Affordable Care Act, many are likely to face increasing financial and competitive pressures that may threaten their survival.     

The effect of the availability of charity care to the uninsured on the demand for private health insurance

The economic reasons why some people do not obtain health insurance are unclear. In this paper, I test the hypothesis that the availability of charity care to the uninsured reduces the likelihood of obtaining private coverage. I utilize variation in the availability of charity care across the different markets in the Community Tracking Study's Household Survey (CTS-HS) using an "access to care" measure of the uninsured's cost-related difficulties in obtaining medical care, to both aggregate across the various "safety net" providers and control for its potentially endogenous supply. I find evidence supporting this hypothesis for low-income people, in both the individual market and the employment-based group market. I also estimate a joint model of offer and take-up decisions for the group market sample and find that the availability of charity care reduces low-income workers' offer rates but not their take-up rates.     

Accounting for uncertainty in policy decision making: Improving access to pediatric dental care

ObjectiveTo introduce a statistical inference framework for policy decision making on access to pediatric dental care.Data SourcesSecondary data were collected for the state of Colorado for year 2019.Study DesignThe access model was an optimization model, matching the demand (patients) and supply (providers) of dental care. Sampling distributions of model inputs were specified using hierarchical Bayesian models, with hyperparameters informed by prior information derived from multiple data sources. Simultaneous inference was applied to identify areas for access improvement. The model was applied to make inference on the pediatric dental care in Colorado, accounting for financial access, differentiated into public (Medicaid and CHIP), private (commercial and out‐of‐pocket), and without financial access.Data Collection/Extraction MethodsMultiple data sources informed the access measurement approach including: 2017 American Community Survey, 2019 Colorado Dental Board, and 2019 National Provider Plan and Enumeration System, 2019 InsureKidsNow.gov among others.Principal FindingsThe median access measure (travel distance) was greater than the Colorado access standards in 16.9% and 65.1% of census tracts for children with private financial access and publicly insured, respectively. Accounting for uncertainty (confidence level 99%), these percentages decreased to 14.6% and 25.6%, respectively, with mostly suburban and rural tracts failing to meet the standards. The median disparity for Medicaid and CHIP versus private financial access was greater than 5 miles in 84.5% and 81.6% of census tracts, respectively. Accounting for uncertainty (confidence level 99%), these percentages declined to 19.5% and 10.5%, respectively, with significant disparities around the metropolitan areas.ConclusionsWhile many communities failed to meet access standards, when accounting for uncertainty, most urban ones did not fail. Disparities in spatial access between publicly and privately insured were most acute in urban communities. Medicaid insured experienced higher disparities than CHIP insured; those differences were not identified when not accounting for uncertainty.     

Private sector contributions and their effect on physician emigration in the developing world

The contribution made by the private sector to health care in a low- or middle-income country may affect levels of physician emigration from that country. The increasing importance of the private sector in health care in the developing world has resulted in newfound academic interest in that sector’s influences on many aspects of national health systems. The growth in physician emigration from the developing world has led to several attempts to identify both the factors that cause physicians to emigrate and the effects of physician emigration on primary care and population health in the countries that the physicians leave. When the relevant data on the emerging economies of Ghana, India and Peru were investigated, it appeared that the proportion of physicians participating in private health-care delivery, the percentage of health-care costs financed publicly and the amount of private health-care financing per capita were each inversely related to the level of physician expatriation. It therefore appears that private health-care delivery and financing may decrease physician emigration. There is clearly a need for similar research in other low- and middle-income countries, and for studies to see if, at the country level, temporal trends in the contribution made to health care by the private sector can be related to the corresponding trends in physician emigration. The ways in which private health care may be associated with access problems for the poor and therefore reduced equity also merit further investigation. The results should be of interest to policy-makers who aim to improve health systems worldwide.     

Wyoming physicians are significant providers of safety net care

BACKGROUND: This study describes the contributions of family and general practice physicians from Wyoming to the health care safety net. METHODS: We surveyed family and general practice physicians in Wyoming about provider demographics, practice composition, and policies for treating the underinsured or uninsured. Two-tailed chi(2) tests and limited logistic regressions were used to test for differences among characteristics of safety net providers. RESULTS: From a 50% response rate, 61% made less than the national mean family physician income (USD$130,000), and women are less likely than men to make this mean income, even when controlling for hours worked (OR, 0.09; CI, 0.009, 0.862). Close to two thirds claimed bad debt of over USD $10,000, and 29.3% noted forgiven debt of over USD $10,000. Physicians with less income than the prior year were more likely to decrease their charity care. CONCLUSIONS: Wyoming family and general practice physicians provide significant amounts of informal safety net care, which is threatened by income loss. Thoughtful public policy is needed to ensure that vulnerable rural Americans have access to care that is not tied to the financial well being of their health care providers.     

Spillovers and vulnerability: the case of community uninsurance

This paper studies the uninsured as a vulnerable population. We contend that reducing the size of the uninsured population yields important spillover benefits to the insured population, benefits that go beyond a lower charity care burden. Evidence presented in this paper reinforces studies in the literature that show that problems of health services quality and access facing insured people increase when the proportion of uninsured people in their local communities is greater. The size of such spillover benefits is reduced if the local market is large enough to be segmented based on insurance status.     

Crowd-Out and Emergency Department Utilization

When consumers gain Medicaid, their cost of healthcare changes. The direction of this change determines how utilization changes. The previously uninsured see a stark decrease in the price of primary care after gaining public insurance. Due to charity care, they may face an increase in the price of emergency department care. The previously insured see a reduction in emergency department prices and decreased access to primary care. We examine the impact of the prior insurance status of the newly publicly insured on substitution between healthcare. We base our identification on California’s LIHP and ACA Medicaid expansions. One challenge we face is estimating crowd-out. We use machine learning techniques to predict prior insurance status based on observable covariates in cross-sectional data. We find an increase in emergency department utilization caused entirely by those crowded-out whose access to primary care has decreased. We find the opposite utilization patterns for the previously uninsured.
