The role of health insurance on treatment for opioid use disorders: Evidence from the Affordable Care Act Medicaid expansion

We estimate the effect of health insurance coverage on opioid use disorder treatment utilization and availability by exploiting cross-state variation in effective dates of Medicaid expansions under the Affordable Care Act. Using a difference-in-differences design, we find that aggregate opioid admissions to specialty treatment facilities increased 18% in expansion states, most of which involved outpatient medication-assisted treatment (MAT). Opioid admissions from Medicaid beneficiaries increased 113% without crowding out admissions from individuals with other health insurance. These effects appeared to be driven by market entry of select MAT providers and by greater acceptance of Medicaid payments among existing MAT providers. Moreover, effects were largest in expansion states with comprehensive MAT coverage. Our findings suggest that Medicaid expansions resulted in substantial utilization and availability gains to clinically efficacious and cost-effective pharmacological treatments, implying potential benefits of expanding Medicaid to non-expansion states and extending MAT coverage.

Effects of health insurance coverage on risky behaviors.

Prior to implementation of the Patient Protection and Affordable Care Act, dependent health insurance coverage was typically available only for young adults under the age of 19. As of September 2010, the Affordable Care Act extended dependent health insurance coverage to include young adults up to the age of 26. I use the National Health Interview Survey for the sample period from 2011 to 2013 to analyze the causal relationship between the expansion of dependent coverage and risky behaviors including smoking and drinking as well as preventive care. I employ a regression discontinuity design to estimate the causal effect of health insurance coverage and overcome the endogeneity problem between insurance status and risky behaviors. When young adults become 26years old, they are 7 to 10 percentage points more likely to lose health insurance than young adults under the age of 26. Although young adults over the age of 26 are generally aged out of insurance coverage, presence or absence of health insurance does not affect their smoking and drinking behaviors and their access to preventive care.

Breast cancer screening among women in Namibia: explaining the effect of health insurance coverage and access to information on screening behaviours.

Breast cancer contributes substantially to morbidity and mortality in Namibia as is the case in most countries in Sub-Saharan Africa (SSA). However, there is a dearth of nationally representative studies that examine the odds of screening for breast cancer in Namibia and SSA at large. This paper aims to fill this gap by examining the determinants of breast cancer screening guided by the Health Belief Model. We applied hierarchical binary logit regression models to explore the determinants of breast cancer screening using the 2013 Namibia Demography and Health Survey (NDHS). We accounted for the effect of unobserved heterogeneity that may affect breast cancer, testing behaviours among women cluster level. The NDHS is a nationally representative dataset that has recently started to collect information on cancer screening. The results show that women who have health insurance coverage (odds ratio (OR) = 1.62, p ≤ 0.01), maintain contact with health professionals (OR = 1.47, p = 0.01), and who have secondary (OR = 1.38, p = 0.01) and higher (OR = 1.77, p ≤ 0.01) education were more likely to be screened for breast cancer. Factors that influence women's perception of their susceptibility to breast cancer such as birthing experience, age, region and place of residence were associated with screening in this context. Overall, the health belief model predicted women's testing behaviours and also revealed the absence of relevant risk factors in the NDHS data that might influence screening. Overall, our results show that strategies for early diagnosis of breast cancer should be given major priority by cancer control boards as well as ministries of health in SSA. These strategies should centre on early screening and may involve reducing or eliminating barriers to health care, access to relevant health information and encouraging breast self-examination.

Why Health Insurance Matters-and Why Research Evidence Should Too.

In the current debate over the future of the Affordable Care Act (ACA), research evidence on the impact of the law and the effects of health insurance coverage in general is critical. Studies of health insurance expansion over the past decade have demonstrated that coverage expansions can produce significant reductions in mortality-particularly among minorities, those living in poorer areas, and those with chronic conditions potentially treatable with timely medical care. More recent studies of the ACA in particular demonstrate that the law has produced historically large reductions in the uninsured rate, with resulting improvements in access to care, perceived quality of care, and self-reported health. Yet much of the general public and many policy makers remain unaware of this evidence. Researchers and clinicians in academic medicine have a role to play in ensuring that critically important health policy decisions are made using rigorous evidence to best protect the interests of our patients.

The effects of access to health insurance: Evidence from a regression discontinuity design in Peru

In many countries large parts of the population do not have access to health insurance. Peru has made an effort to change this in the early 2000s. The institutional setup gives rise to the rare opportunity to study the effects of health insurance coverage exploiting a sharp regression discontinuity design. We find large effects on utilization that are most pronounced for the provision of curative care. Individuals seeing a doctor leads to increased awareness about health problems and generates a potentially desirable form of supplier-induced demand: they decide to pay themselves for services that are in short supply.

The effect of health insurance coverage and the doctor-patient relationship on health care utilization in high poverty neighborhoods.

African Americans have higher rates of mortality than whites who are the same age and sex. We hypothesize that in low socioeconomic status neighborhoods, having health insurance coverage and a regular health care provider increases the likelihood of receiving diagnostic tests for cardiovascular disease and diabetes. We use data from a random two-stage cluster sample of 230 adults living in high poverty census tracts to examine the effects of insurance coverage and having a regular doctor on the likelihood receiving diagnostic tests for high cholesterol, high blood sugar, and blood pressure. We find that health insurance coverage increases the odds of having a regular health care provider (p < 0.05) and of receiving the diagnostic tests (p < 0.05). Having a regular doctor mediates the effect of insurance coverage on the likelihood of receiving the tests, especially when the participant can report the physician's name.

The impact of health insurance on maternal health care utilization: evidence from Ghana, Indonesia and Rwanda.

While research has assessed the impact of health insurance on health care utilization, few studies have focused on the effects of health insurance on use of maternal health care. Analyzing nationally representative data from the Demographic and Health Surveys (DHS), this study estimates the impact of health insurance status on the use of maternal health services in three countries with relatively high levels of health insurance coverage—Ghana, Indonesia and Rwanda. The analysis uses propensity score matching to adjust for selection bias in health insurance uptake and to assess the effect of health insurance on four measurements of maternal health care utilization: making at least one antenatal care visit; making four or more antenatal care visits; initiating antenatal care within the first trimester and giving birth in a health facility. Although health insurance schemes in these three countries are mostly designed to focus on the poor, coverage has been highly skewed toward the rich, especially in Ghana and Rwanda. Indonesia shows less variation in coverage by wealth status. The analysis found significant positive effects of health insurance coverage on at least two of the four measures of maternal health care utilization in each of the three countries. Indonesia stands out for the most systematic effect of health insurance across all four measures. The positive impact of health insurance appears more consistent on use of facility-based delivery than use of antenatal care. The analysis suggests that broadening health insurance to include income-sensitive premiums or exemptions for the poor and low or no copayments can increase use of maternal health care.

The Influences of Health Insurance and Access to Information on Prostate Cancer Screening among Men in Dominican Republic.

Objectives. Although research demonstrates the public health burden of prostate cancer among men in the Caribbean, relatively little is known about the factors that underlie the low levels of testing for the disease among this population. Study Design. A cross-sectional study of prostate cancer testing behaviours among men aged 40–60 years in Dominican Republic using the Demographic and Health Survey (2013). Methods. We use hierarchical binary logit regression models and average treatment effects combined with propensity score matching to explore the determinants of prostate screening as well as the average effect of health insurance coverage on screening. The use of hierarchical binary logit regression enabled us to control for the effect of unobserved heterogeneity at the cluster level that may affect prostate cancer testing behaviours. Results. Screening varied significantly with health insurance coverage, knowledge of cholesterol level, education, and wealth. Insured men were more likely to test for prostate cancer (OR = 1.65, p = 0.01) compared to the uninsured. Conclusions. The expansion and restructuring of Dominican Republic universal health insurance scheme to ensure equity in access may improve health access that would potentially impact positively on prostate cancer screening among men.

EPSDT Care and Emergency Department Visits for Non-Urgent Care: Hispanic vs. Non-Hispanic Children in a Border Community

Objectives: We examine the use of emergency departments for non-urgent care, comparing children who received recommended EPSDT services to those who do not, analyzing differences between Hispanic and Non-Hispanic children, controlling for differences in their characteristics. Methods: A retrospective, longitudinal study of a cohort of approximately 6,000 children during the years from 1999-2009 using data from hospital and emergency department (ED) claims, paediatric office visits and claims data from Medicaid (AHCCCS) and SCHIP. Three different versions of an econometric model are presented. The estimates also include the effects of health insurance coverage and the lack thereof by evaluating the records of all children age 0-19 in Yuma County who met any of the following criteria: insured by Medicaid or SCHIP at any time; or used the emergency department (ED) or any other participating provider during the ten years; or were immunized. We test if the provision of recommended EPSDT services by age two, affected the subsequent number of nonurgent care visits to hospital’s ED. Results: Children without continuous health insurance coverage are twice as likely as continuously insured children to use and ED for non-urgent care. Controlling for health insurance coverage and demographics, the receipt of recommended EPSDT care by age two significantly reduces non-urgent care visits to the ED for Hispanic children. In some instances the likelihood of such visits is cut in half. Conclusion: The results suggest that the provision of EPSDT services to the growing number of Hispanic children can yield significant benefits.

The effect of health insurance coverage on medical care utilization and health outcomes: Evidence from Medicaid adult vision benefits

Increasing the proportion of adults that have regular, comprehensive eye exams and reducing visual impairment due to uncorrected refractive error and other common eye health problems are federal health objectives. We examine the effect of vision insurance on eye care utilization and vision health outcomes by taking advantage of quasi-experimental variation in Medicaid coverage of adult vision care. Using a difference-in-difference-in-difference approach, we find that Medicaid beneficiaries with vision coverage are 4.4 percentage points (p<0.01) more likely to have seen an eye doctor in the past year, 5.3 percentage points (p<0.01) less likely to report needing but not purchasing eyeglasses or contacts due to cost, 2.0 percentage points (p<0.05) less likely to report difficulty seeing with usual vision correction, and 1.2 percentage points (p<0.01) less likely to have a functional limitation due to vision.

Poverty, Health Insurance Status, and Health Service Utilization Among the Elderly

Research on health service utilization among the elderly is unambiguous in finding that those who are the most heavily insured use the most health services. What is less clear, however, is whether the favorable effect of health insurance coverage holds for low-income populations. As such, this study uses data from the Rand version of the Health Retirement Study spanning the years 2002 to 2010 to examine the extent of heterogeneous use of health services within the population of elderly poor and the degree to which health insurance status moderates the effect of poverty on health service utilization.

Spillovers from health insurance to the US underground economy

Employing recent data on the prevalence of the underground economy across states in the United States, this article uniquely studies the nexus between health insurance coverage and the underground economy. We find a positive effect of health insurance coverage on the spread of the underground sector. Upon disaggregation, while private health coverage promotes the underground sector, government health insurance has the opposite effect.

Effect of health insurance coverage on labor allocation: evidence from US farm households.

In the past three decades, farm families have relied on government payments and off-farm income to reduce income risk and increase total household income. Many studies have analyzed the role of government payments; however, little is known about the impact of health insurance coverage on labor allocation. This study builds on previous literature by using copulas to test for dependence in the labor allocation, addressing the importance of fringe benefits to the farm household, and determining how these considerations affect our knowledge of the impact of fringe benefits on off-farm labor. The results indicate that the off-farm hours worked by the operator and spouse are jointly determined; health insurance coverage is an endogenous variable. Using the predicted probability of insurance coverage and joint estimation techniques, we find a positive and highly significant relationship with the hours worked off-farm. Further, we find that both coupled and decoupled payments are negatively correlated with the hours worked off-farm.

The effect of health insurance coverage on the reported health of young adults

We exploit a sharp change in the likelihood that an individual is covered by health insurance when he/she turns 19 years of age to study how health insurance affects reported health status. We find that an individual is 6 percentage points less likely to have health insurance when he/she turns 19. Using a fuzzy regression discontinuity design, we find that having health coverage significantly increases the likelihood of reporting excellent health among young adults.

Source of Health Insurance Coverage and Employment Survival Among Newly Disabled Workers: Evidence from the Health and Retirement Study

The onset of a work-limiting disability sets in motion a sequence of events that for a growing number of workers ends in early retirement from the labor force, SSDI application and, ultimately, long-term program participation. Exactly how this sequence of events plays out is not well understood. While there exist large bodies of literature that address the effects of health insurance coverage on a wide range of outcomes, few papers have sought to examine how source of health insurance coverage generally and employer sponsored health insurance (ESHI) specifically affect the employment trajectory following onset of disability. The authors use the nationally representative, longitudinal data from the Health and Retirement Study (HRS) to observe individuals before and after they experience a self-reported work limiting disability. To estimate the effect of ESHI on labor supply and disability claiming, they compare individuals covered by ESHI with no other employer-sponsored option (i.e., spousal coverage) with individuals covered by ESHI but whose spouses are offered coverage from their own employer. They find evidence of an “employment lock” effect of ESHI only among the 20 percent of individuals whose disabilities do not impact their immediate physical capacity but are associated with high medical costs. They do not find any evidence of differential disability insurance application rates between those with ESHI and the comparison group. With the passage of the Affordable Care Act, there is concern that disability insurance applications may swell because the incentive to remain employed will diminish for disabled workers reliant on ESHI. Their results suggest that the availability of non-employment-based health insurance may cause disabled workers with high cost/low severity conditions to leave the workforce but it will not necessarily lead to increased disability insurance application among individuals with ESHI.

The Effects of Health Insurance Coverage on the Math Achievement Trajectories of School Children in Yuma County, Arizona: Implications for Education Accountability Policy

U.S. Federal and state education policies place considerable emphasis on assessing the effects that schools and teachers have on student test score performance. It is important for education policy makers to also consider other factors that can affect student achievement. This study finds that an exogenous school factor, discontinuous health insurance coverage, leads to a deficit in math achievement over time. A sample of Yuma County, Arizona public school students who experienced an illness or injury and whose health insurance coverage status was known were selected for inclusion into the study over five consecutive school years (1999 – 2003). The longitudinal math achievement trajectory of students who had private health insurance coverage was compared to students who had discontinuous coverage. Net of a student’s poverty status and other background characteristics the findings suggest that students who experienced a health event when they had no healthcare insurance had the same growth rate but lower overall math achievement. The average achievement gap was a constant -8.84 scale score points. However, separate analyses for specific types of illness/injury suggest the achievement deficit varied considerably and is typically larger.Other important findings from the study suggest that students who maintained continuous health insurance coverage through the SCHIP/Medicaid program had steeper, positive achievement gains than either those with private coverage or those who experience coverage gaps.

Efficiency of health care delivery systems: effects of health insurance coverage

Health insurance expansions may increase the demand for care-creating incentives for health systems to increase input consumption. The possibility remains that added capacity and personnel will have little effect on health outcomes, decreasing the technical efficiency of health care delivery systems. We estimate that a 1 percentage point increase in health insurance coverage decreases the technical efficiency of health care delivery by 1.3 percentage points, translating into approximately 50 billion dollars in additional health expenditures. This finding uncovers a previously unexplored consequence of changes in health insurance on the supply side of health care markets suggesting one avenue through which health care costs growth may occur.

Health insurance for the poor decreases access to HIV testing in antenatal care: evidence of an unintended effect of health insurance reform in Colombia

Prevention of mother-to-child transmission of HIV was added to standard antenatal care (ANC) in 2000 for Colombians enrolled in the two national health insurance schemes, the ‘subsidized regime’ (covering poor citizens) and the ‘contributory regime’ (covering salaried citizens with incomes above the poverty threshold), which jointly covered 80% of the total Colombian population as of 2007. This article examines integration of HIV testing in ANC through the relationship between ordering an HIV test with the type of health insurance, including lack of health insurance, using data from the nationally representative 2005 Colombia Demographic and Health Survey. Overall, health-care providers ordered an HIV test for only 35% of the women attending ANC. We regressed the order of an HIV test during ANC on health systems characteristics (type of insurance and type of ANC provider), women’s characteristics (age, wealth, educational attainment, month of pregnancy at first antenatal visit, HIV knowledge, urban vs. rural residence and sub-region of residence) and children’s characteristics (birth order and birth year). Women enrolled in the subsidized regime were significantly less likely to be offered and receive an HIV test in ANC than women without any health insurance (adjusted odds ratio = 0.820, P < 0.001), when controlling for the other independent variables. Wealth, urban residence, birth year of the child and the type of health-care provider seen during the ANC visit were significantly associated with providers ordering an HIV test for a woman (all P < 0.05). Our findings suggest that enrolment in the subsidized regime reduced access to HIV testing in ANC. Additional research is needed to elucidate the mechanisms through which the potential effect of health insurance coverage on HIV testing in ANC occurs and to examine whether enrolment in the subsidized regime has affected access to other essential health services.

The Affordable Care Act and Reproductive Health: Potential Gains and Serious Challenges

After nearly a century of failed or incomplete legislative efforts, the Patient Protection and Affordable Care Act (PPACA), enacted by Congress in March 2010, establishes the principle that every American is entitled to affordable and effective health insurance coverage regardless of income or health status. Although many aspects of the act have received broad attention, its impact on reproductive health has received considerably less scrutiny, except when debated through the specific lens of particularly polarized ideological concerns. If fully implemented as planned, the PPACA has the potential to improve reproductive health in the United States in at least three ways: increasing the number of women and men with insurance coverage; increasing the value of insurance coverage for addressing reproductive health needs; and improving access to reproductive health services and information more generally. Several PPACA provisions stand out as having particular importance for reproductive health, including Medicaid family planning expansions, standards for an essential health benefits package, expanded coverage for contraception and other clinical preventive services, and teen pregnancy prevention programs. All these potential gains, however, are threatened by political, economic, and logistical challenges to the PPACA and by flaws in the legislation itself.

The Effect of Health Insurance Coverage on the Use of Medical Services

Substantial uncertainty exists regarding the causal effect of health insurance on the utilization of care. We exploit a sharp change in insurance coverage rates that results from young adults “aging out” of their parents' insurance plans to estimate the effect of insurance coverage on the utilization of emergency department (ED) and inpatient services. Aging out results in an abrupt 5 to 8 percentage point reduction in the probability of having health insurance. We find that uninsured status leads to a 40 percent reduction in ED visits and a 61 percent reduction in inpatient hospital admissions. (JEL G22, I11, I18)
