Medicaid Expansion Produces Long-Term Impact on Insurance Coverage Rates in Community Health Centers
Journal of Primary Care & Community Health
Background:It is crucial to understand the impact of the Affordable Care Act (ACA). This study assesses changes in insurance status of patients visiting community health centers (CHCs) comparing states that expanded Medicaid to those that did not. Methods: Electronic health record data on 875,571 patients aged 19 to 64 years with ≥ 1 visit between 2012 and 2015 in 412 primary care CHCs in 9 expansion and 4 nonexpansion states. We assessed changes in rates of total, uninsured, Medicaid-insured, and privately insured primary care and preventive care visits; immunizations administered, and medications ordered. Results: Rates of uninsured visits decreased pre-to post-ACA, with greater drops in expansion (−57%) versus nonexpansion (−20%) states. Medicaid-insured visits increased 60% in expansion states while remaining unchanged in nonexpansion states. Privately insured visits were 2.7 times higher post-ACA in nonexpansion states with no increase in expansion states. Comparing 2015 with 2014: Uninsured visit rates continued to decrease in expansion (−28%) and nonexpansion states (−19%), Medicaid-insured rates did not significantly increase, and privately insured visits increased in nonexpansion states but did not change in expansion states. Conclusions: Medicaid expansion and subsidies to purchase private coverage likely increased the accessibility of health insurance for patients who had previously not been able to access coverage.

Medicaid expansion had great potential to affect community health centers (CHCs), particularly in rural areas, because their patients are predominantly low income and disproportionately uninsured. Using data for 2011-15 on all CHCs, we found that after two years Medicaid expansion was associated with an 11.44-percentage-point decline in the share of CHC patients who were uninsured and a 13.15-percentage-point increase in the share with Medicaid. Changes in quality and volume were consistently observed in rural CHCs in expansion states, which had relative improvements in asthma treatment, body mass index screening and follow-up, and hypertension control, along with substantial increases in volumes for eighteen of twenty-one types of visits-particularly those for mammograms, abnormal breast findings, alcohol-related disorder, and other substance abuse disorder. Similar relative gains were not observed in urban CHCs in expansion states. Repealing or phasing out Medicaid expansion could...

To determine the impact of Medicaid expansion on access to preventative care and non-emergent emergency department (ED) use for existing Medicaid enrollees. Study Design: The primary and secondary outcomes were receipt of annual preventive care visit and non- emergent emergency department (ED) visits, respectively. A logistic state-level, matched, difference in difference regression model was used for the primary analysis and a Poisson specification was used for the secondary analysis. Models controlled for patient characteristics and accounted for the complex longitudinal survey design.
Community Health Center Use After Oregon's Randomized Medicaid Experiment
The Annals of Family Medicine, 2015
PURPOSE There is debate about whether community health centers (CHCs) will experience increased demand from patients gaining coverage through Affordable Care Act Medicaid expansions. To better understand the effect of new Medicaid coverage on CHC use over time, we studied Oregon's 2008 randomized Medicaid expansion (the "Oregon Experiment"). METHODS We probabilistically matched demographic data from adults (aged 19-64 years) participating in the Oregon Experiment to electronic health record data from 108 Oregon CHCs within the OCHIN community health information network (originally the Oregon Community Health Information Network) (N = 34,849). We performed intent-to-treat analyses using zero-inflated Poisson regression models to compare 36-month (2008-2011) usage rates among those selected to apply for Medicaid vs not selected, and instrumental variable analyses to estimate the effect of gaining Medicaid coverage on use. Use outcomes included primary care visits, behavioral/mental health visits, laboratory tests, referrals, immunizations, and imaging. RESULTS The intent-to-treat analyses revealed statistically significant differences in rates of behavioral/mental health visits, referrals, and imaging between patients randomly selected to apply for Medicaid vs those not selected. In instrumental variable analyses, gaining Medicaid coverage significantly increased the rate of primary care visits, laboratory tests, referrals, and imaging; rate ratios ranged from 1.27 (95% CI, 1.05-1.55) for laboratory tests to 1.58 (95% CI, 1.10-2.28) for referrals. CONCLUSIONS Our results suggest that use of many different types of CHC services will increase as patients gain Medicaid through Affordable Care Act expansions. To maximize access to critical health services, it will be important to ensure that the health care system can support increasing demands by providing more resources to CHCs and other primary care settings.
Impact of community health centers and Medicaid on the use of health services
PubMed, 1980
The impact of improved access to health care through the Federal community health center (CHC) and Medicaid programs was examined in five urban low-income areas. Data on access to care and physician, hospital, and dental services utilization were collected by baseline and followup health surveys in the CHCs' services areas. There was a shift in use from hospital clinics to CHCs. Followup surveys indicated that 23 percent of the population reported CHCs as usual source of care. Travel time to source of care was reduced for users of CHCs. Medicaid coverage of the population in the survey areas increased from 16 to 37 percent between the baseline and followup surveys, an interval of 4 to 7 years. Increases occurred in the use of physicians and dental care between the baseline and followup surveys, but the rates scarcely kept pace with the national rates. Respondents who reported CHCs as their usual source of care, however, had a higher rate of physician visits and a lower rate of hospitalization compared with those using private physicians or hospital clinics as the usual source of care. Respondents with Medicaid coverage usually had higher physician and hospital use, irrespective of usual source of care. Both CHC and Medicaid programs contributed to increased use of dental care by providing financial and dental care resources. Although these two programs greatly facilitated the use of health services, disparity in physician and dental utilization remains between the five low-income areas and the averages for the nation.
Community Health Centers: Recent Growth and the Role of the ACA
2017
Community health centers are the nation’s largest source of comprehensive primary care for medically underserved communities and populations. Under the Affordable Care Act (ACA), increased patient revenues due to the expansion of Medicaid and private health insurance, along with substantially increased direct federal investment in the program, have led to growth in the number of health centers and their capacity to provide services. This brief draws on 2015 federal data on health centers and our 2016 Survey of Health Centers’ Experiences and Activities under the Affordable Care Act to provide a snapshot of health centers and their patients, analyze recent changes, and compare the experience of health centers in Medicaid expansion and non-expansion states. This information is germane to the impending debate on the ACA and the potential impact of changes on coverage and access to care for low-income Americans and financing for safety-net providers. Key findings include:
Community Health Centers: A 2013 Profile and Prospects as ACA Implementation Proceeds
2015
In 2013, more than 1,200 federally funded community health centers provided access to care for low-income populations living in medically underserved communities throughout the country. The Affordable Care Act made expansion of health centers a key part of its strategy for ensuring that these communities would realize the benefits of increased health insurance coverage for their residents. As health insurance coverage expands under the Affordable Care Act (ACA) and the demand for primary care increases, the role of health centers is likely to increase. A key question going forward is whether health centers' expanded capacity, developed over the past five years, will be sustained going forward.
Health-Related Outcomes among the Poor: Medicaid Expansion vs. Non-Expansion States
PloS one, 2015
States' decisions not to expand Medicaid under the Affordable Care Act (ACA) could potentially affect access to care and health status among their low-income residents. The 2010-2012 nationally representative Medical Expenditure Panel Survey data were analyzed in 2015 to compare 9755 low-income adults aged 18-64 years from Medicaid-expanding states with 7455 adults from nonexpanding states. Multivariate logistic regression models were fitted to evaluate the differences in access to care, receipt of preventive services, quality of care, attitudes about health and self-reported health status by Medicaid expansion status. The differences in care utilization and medical expenditures between the two groups were examined using a 2-part modeling approach. Compared to their counterparts in Medicaid expansion states, low income adults in the nonexpanding states were more likely to be black and reside in rural areas and were less likely to have a usual source of care (prevalence ratio[PR]...

• Recent federal proposals to use block grants or per capita caps to fund Medicaid would likely lead to cuts in Medicaid funding for health centers, which are an important source of care for Medicaid enrollees. • Recent Medicaid §1115 waivers are seeking to change state-level enrollment and eligibility requirements in ways that are expected to adversely affect health center revenues. • Proposed Medicaid funding cuts are expected to lead to reductions in service capacity across all health centers over the long term. • State policymakers should understand the likely impacts of proposed Medicaid program changes on health centers in their states and allocate funding to help offset lost federal financing.
