Effect of the Medicaid primary care rate increase on prenatal care utilization among Medicaid-insured women.
The purpose of this study was to evaluate the effect of the 2013-2014 ACA Medicaid Primary Care Rate Increase on Medicaid-insured women's prenatal care utilization, overall and by race and ethnicity. The investigators concluded that the Medicaid "fee bump" improved prenatal care utilization for non-Hispanic Black and White women. They suggest that policymakers may consider reinstating higher Medicaid reimbursements to improve access to care for disadvantaged populations.

Where do Oregon Medicaid Enrollees seek outpatient care post-Affordable Care Act Medicaid expansion?
The purpose of this study was to understand where Oregon Medicaid beneficiaries sought care after the Patient Protection and Affordable Care Act Medicaid expansion (emergency department, primary care, or specialist) and the interaction between primary care establishment and outpatient care utilization. Results showed that most newly and returning-insured Medicaid enrollees sought primary care rather than emergency department services and most became established with primary care, suggesting that both insurance and primary care continuity play a role in where patients seek health care services.

Changes in hospital service demand, cost, and patient illness severity following health reform.
This study examined the effects of expanded Medicaid coverage and the health insurance exchange on the number of hospital inpatient and emergency department (ED) utilization rates, cost, and patient illness severity. There was a significant drop in uninsured inpatient discharges and ED visits in states where Medicaid was expanded. For all by young females, uninsured inpatient discharge rates fell by 39% or greater. In nonexpansion states, the rates remained unchanged or increased slightly. Changes in all-payer and private insurance rates were not as dramatic, as was inpatient costs per discharge and all-payer inpatient costs.

Cervical and colorectal cancer screening prevalence before and after Affordable Care Act Medicaid expansion.
This study assessed changes in the prevalence of cervical and colorectal cancer screening from before and after the Affordable Care Act in Medicaid expansion and non-expansion states among patients seen in community health centers. Results showed that, despite increased prevalences of cervical and colorectal cancer screening in both expansion and non-expansion states across all race/ethnicity groups, rates remained suboptimal for this population of socioeconomically disadvantaged patients.

Two-state comparison of total joint arthroplasty utilization following Medicaid expansion.
The aim of this study was to determine whether Medicaid expansion was associated with increased utilization rates of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Illinois (which expanded Medicaid) relative to Missouri (which did not expand Medicaid). The investigators concluded that their study demonstrated that Medicaid expansion in Illinois was associated with increased utilization of THA and TKA. They suggested that further study is needed to understand the impact of Medicaid expansion in other states and for other procedures.

Does a transition to accountable care in Medicaid shift the modality of colorectal cancer testing?
This study investigated whether Medicaid expansion due to the Affordable Care Act (ACA) increased the number of patients who tested for colorectal cancer (CRC). Results in Oregon showed that there was an increased in statewide fecal testing mainly in Coordinated Care Organizations (CCOs).

Association between Medicaid adult nonemergency dental benefits and dental services use and expenditures.
AHRQ researchers compared nonemergency dental services use in states with and without Medicaid adult nonemergency dental benefits. Dental use increased in states with the Medicaid dental benefit. Out-of-pocket expenses decreased approximately 19 percent in covered states.

The effect of health insurance on prescription drug use among low-income adults: evidence from recent Medicaid expansions.
This study examined how subsidized coverage affected prescription drug utilization among low-income non-elderly adults. Among other results, the investigators found that within the first 15 months of new health insurance availability, aggregate Medicaid-paid prescriptions increased 19 percent, amounting to nearly 9 new prescriptions a year, per new enrollee. They also found no evidence of reductions in uninsured or privately-insured prescriptions, suggesting that new coverage did not simply substitute for other payment sources.

Preventive care use among justice-involved and non-justice-involved youth.
The objective of this study was to determine how rates of well-child (WC) and emergency department visits, as well as public insurance enrollment continuity, differed between youth involved in the justice system (JIY) and youth who have never been in the system (NJIY). It found that JIY had lower use rates of WC visits and higher use rates of emergency services in comparison with NJIY. JIY had more and longer gaps in Medicaid coverage compared with NJIY.

Recent health care use and Medicaid entry of Medicare beneficiaries.
The purpose of this study was to examine the relationship between Medicaid entry and recent health care use among Medicare beneficiaries. Although recent health care use predicted greater likelihood of Medicaid entry, half of new Medicaid participants used no hospital or nursing home care during the study period.

What factors are associated with Medicaid patients' use of health centers?.
This study identified patient and neighborhood factors associated with health center (HC) use. Dually eligible patients and those with high chronic disease burden had lower odds of HC use. Temporary Assistance for Needy Families participants and Hispanic beneficiaries had higher odds. Local HC presence predicted higher HC use.

Impact of comorbidities among Medicaid enrollees with chronic obstructive pulmonary disease, United States, 2009.
Researchers quantified the cost of Medicaid-insured patients with chronic obstructive pulmonary disease (COPD) co-diagnosed with other chronic disorders. They concluded that comorbidities markedly increased health services use among people with COPD insured with Medicaid, although ED visits in this study were predominantly unrelated to COPD. Acute care, hospital bed days, and total Medicaid-reimbursed costs increased as the number of comorbidities increased.
