Association of dual Medicare and Medicaid eligibility with outcomes and spending for cancer surgery in high-quality hospitals.
The purpose of this study was to assess whether treatment at high-quality hospitals mitigates dual-eligibility-associated disparities in outcomes and spending for cancer surgery. Medicare beneficiaries 65 years or older who underwent colectomy, rectal resection, lung resection, or pancreatectomy were evaluated. The findings indicate that, even among the highest-quality hospitals, dual-eligibility patients had poorer outcomes and higher spending. Dually eligible patients were more likely to be discharged to a facility and thus incurred higher post-acute care costs. Although treatment at high-quality hospitals is associated with reduced differences in outcomes, dual-eligibility patients remain at high risk for adverse post-operative outcomes as well as increased readmissions and post-acute care use.

Medicaid Accountable Care Organizations and childbirth outcomes.
This study examined the impact of Accountable Care Organizations (ACOs) to childbirth outcomes. States that use Medicaid ACOs were compared with states that had not adopted ACO. Using HCUP data, the relationship between Medicaid ACO adoption and neonatal and maternal outcomes, and cost per birth was examined. Medicaid ACO implementation was associated with a moderate reduction in hospital costs per birth and decreased cesarean section rates with results varying by state. There was no association with other birth outcomes, including infant inpatient mortality, low birthweight, neonatal intensive care unit utilization and severe maternal morbidity.

Outcomes of Medicaid home- and community-based long-term services relative to nursing home care among dual eligibles.
This study measured the outcomes of dual-eligible recipients of Medicaid home- and community-based long-term services (HCBS) compared to nursing home residents. The authors used the 2005 and 2012 Medicaid Analytic eXtract (MAX) database, a national compilation of Medicaid claims which merges Medicare claims to identify hospital admissions. A cohort of 1,312,498 older adults dually enrolled in Medicaid and Medicare and using long-term care was tracked. HCBS users were found to have 10 percent points higher annual rates of hospitalization than their nursing home counterparts when selection bias is addressed. The differences persisted across races, dementia status, and intensity of HCBS spending.

Impact of long-term buprenorphine treatment on adverse health care outcomes In Medicaid.
The optimal, or even minimum, duration of medication treatment for opioid use disorder (OUD) needed to improve long-term outcomes has not been established empirically. As a result, health plans set potentially restrictive treatment standards to guide benefits and payment. To address this gap, the investigators used a National Quality Forum measure for OUD medication treatment duration (180 days) to examine the impact of longer treatment on health care outcomes within a key population of Medicaid enrollees.

Do Medicaid benefit expansions have teeth? The effect of Medicaid adult dental coverage on the use of dental services and oral health.
This article examines the effect of Medicaid adult dental coverage on use of dental care and dental health outcomes using state-level variation in dental coverage during 2000-2012. Its findings imply that dental coverage is associated with an increase in the likelihood of a recent dental visit, with the size of the effect increasing with Medicaid payment rates to dentists, and a reduction in the likelihood of untreated dental caries.

The effect of health insurance coverage on medical care utilization and health outcomes: evidence from Medicaid adult vision benefits.
The reserarchers examined 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. They found that Medicaid beneficiaries with vision coverage are 4.4 percentage points more likely to have seen an eye doctor in the past year,and 5.3 percentage points less likely to report needing but not purchasing eyeglasses or contacts due to cost.

Validity of maternal and infant outcomes within nationwide Medicaid data.
The researchers aimed to assess the validity of preeclampsia, congenital cardiac malformations, and persistent pulmonary hypertension of the newborn diagnoses in the U.S. Medicaid Analytic eXtract (MAX), a database that may be useful for perinatal research. The positive predictive values were conservative, particularly when restricting to infants not transferred to another facility shortly after birth because only records from a single hospitalization were reviewed.
