Changes in Health Care Access, Behaviors, and Self-reported Health Among Low-income US Adults Through the Fourth Year of the Affordable Care Act.

ABSTRACT:

Background

Health care access increased for low-income Americans under the Affordable Care Act (ACA). It is unknown whether these changes in access were associated with improved self-reported health.

Objective

Determine changes in health care access, health behaviors, and self-reported health among low-income Americans over the first 4 years of the ACA, stratified by state Medicaid expansion status.

Design

Interrupted time series and difference-in-differences analysis.

Subjects

Noninstitutionalized US adults (18-64 y) in low income households (<138% federal poverty level) interviewed in the Behavioral Risk Factor Surveillance System 2011-2017 (N=505,824).

Measures

Self-reported insurance coverage, access to a primary care physician, avoided care due to cost; self-reported general health, days of poor physical health, days of poor mental health days, and days when poor health limited usual activities; self-reported health behaviors, use of preventive services, and diagnoses.

Results

Despite increases in access, the ACA was not associated with improved physical or general health among low-income adults during the first 4 years of implementation. However, Medicaid expansion was associated with fewer days spent in poor mental health (-1.1 d/mo, 95% confidence interval: -2.1 to -0.5). There were significant changes in specific health behaviors, preventive service use, and diagnosis patterns during the same time period which may mediate the relationship between the ACA rollout and self-reported health.

Conclusion

In nationally-representative survey data, we observed improvements in mental but not physical self-reported health among low-income Americans after 4 years of full ACA implementation.

Project description:Importance:Cancer survivors face ongoing health issues and need access to affordable health care, yet studies examining health care access and affordability in this population are lacking. Objectives:To evaluate health care access and affordability in a national sample of cancer survivors compared with adults without cancer and to evaluate temporal trends during implementation of the Affordable Care Act. Design, Setting, and Participants:We used data from the National Health Interview Survey from 2010 through 2016 to conduct a population-based study of 30?364 participants aged 18 years or older. We grouped participants as cancer survivors (n?=?15?182) and those with no reported history of cancer, whom we refer to as control respondents (n?=?15?182), matched on age. We excluded individuals reporting a cancer diagnosis prior to age 18 years and those with nonmelanoma skin cancers. Main Outcomes and Measures:We compared issues with health care access (eg, delayed or forgone care) and affordability (eg, unable to afford medications or health care services) between cancer survivors and control respondents. We also explored trends over time in the proportion of cancer survivors reporting these difficulties. Results:Of the 30?364 participants, 18?356 (57.4%) were women. The mean (SD) age was 63.5 (23.5) years. Cancer survivors were more likely to be insured (14?412 [94.8%] vs 13?978 [92.2%], P?<?.001) and to have government-sponsored insurance (7266 [44.3%] vs 6513 [38.8%], P?<?.001) compared with control respondents. In multivariable models, cancer survivors were more likely than control respondents to report delayed care (odds ratio [OR], 1.38; 95% CI, 1.16-1.63), forgone medical care (OR, 1.76; 95% CI, 1.45-2.12), and/or inability to afford medications (OR, 1.77; 95% CI, 1.46-2.14) and health care services (OR, 1.46; 95% CI, 1.27-1.68) (P?<?.001 for all). From 2010 to 2016, the proportion of survivors reporting delayed medical care decreased each year (B?=?0.47; P?=?.047), and the proportion of those needing and not getting medical care also decreased each year (B?=?0.35; P?=?.04). In addition, the proportion of cancer survivors who reported being unable to afford prescription medication decreased each year (B=0.66; P?=?.004) and the proportion of those unable to afford at least 1 of 6 services decreased each year (B?=?0.51; P?=?.01). Conclusions and Relevance:Despite higher rates of insurance coverage, cancer survivors reported greater difficulties accessing and affording health care compared with adults without cancer. Importantly, the proportion of survivors reporting these issues continued a downward trend throughout our observation period in the years following the implementation of the Affordable Care Act. Our findings suggest incremental improvement in health care access and affordability after recent health care reform and provide an important benchmark as additional changes are likely to occur in the coming years.

Project description:BackgroundIn 2014, only 26 states and the District of Columbia chose to implement the Patient Protection and Affordable Care Act (ACA) Medicaid expansions for low-income adults.ObjectiveTo evaluate whether the state Medicaid expansions were associated with changes in insurance coverage, access to and utilization of health care, and self-reported health.DesignComparison of outcomes before and after the expansions in states that did and did not expand Medicaid.SettingUnited States.ParticipantsCitizens aged 19 to 64 years with family incomes below 138% of the federal poverty level in the 2010 to 2014 National Health Interview Surveys.MeasurementsHealth insurance coverage (private, Medicaid, or none); improvements in coverage over the previous year; visits to physicians in general practice and specialists; hospitalizations and emergency department visits; skipped or delayed medical care; usual source of care; diagnoses of diabetes, high cholesterol, and hypertension; self-reported health; and depression.ResultsIn the second half of 2014, adults in expansion states experienced increased health insurance (7.4 percentage points [95% CI, 3.4 to 11.3 percentage points]) and Medicaid (10.5 percentage points [CI, 6.5 to 14.5 percentage points]) coverage and better coverage than 1 year before (7.1 percentage points [CI, 2.7 to 11.5 percentage points]) compared with adults in nonexpansion states. Medicaid expansions were associated with increased visits to physicians in general practice (6.6 percentage points [CI, 1.3 to 12.0 percentage points]), overnight hospital stays (2.4 percentage points [CI, 0.7 to 4.2 percentage points]), and rates of diagnosis of diabetes (5.2 percentage points [CI, 2.4 to 8.1 percentage points]) and high cholesterol (5.7 percentage points [CI, 2.0 to 9.4 percentage points]). Changes in other outcomes were not statistically significant.LimitationObservational study may be susceptible to unmeasured confounders; reliance on self-reported data; limited post-ACA time frame provided information on short-term changes only.ConclusionThe ACA Medicaid expansions were associated with higher rates of insurance coverage, improved quality of coverage, increased utilization of some types of health care, and higher rates of diagnosis of chronic health conditions for low-income adults.Primary funding sourceNone.
