Characteristics, utilization, and concentration of outpatient care for dual-eligible Medicare beneficiaries.
The purpose of this study was to describe the distribution of outpatient care for dual-eligible Medicare beneficiaries ("duals") and characterize the intensity of outpatient care utilization of duals vs non-dual-eligible beneficiaries ("nonduals"). The researchers assessed the distribution of outpatient care across physician practices and compared the use of different outpatient services between duals and nonduals. The study found that nearly 80% of outpatient visits for duals were provided by 35% of practices. Compared with low-dual and no-dual practices, high-dual practices served more patients, with morhe comorbidities. Duals had 2 less outpatient visits per year compared with nonduals with substantially fewer subspecialty care visits despite having more comorbidities.

Integrated care models and behavioral health care utilization: quasi-experimental evidence from Medicaid health homes.
This study provided the first population-level evidence on the effects of Medicaid health homes (HH) on behavioral health care service use. As of 2016, 16 states had adopted an HH for enrollees with serious mental illness and/or substance use disorder. Using data from the National Survey on Drug Use and Health, the authors found that HH adoption increased service use among enrollees and enrollee self-reported health improved post-HH.

Effects of Medicaid expansion on postpartum coverage and outpatient utilization.
Timely postpartum care is associated with lower maternal morbidity and mortality, yet fewer than half of Medicaid beneficiaries attend a postpartum visit. Using Medicaid claims data for 2013-2015 from Colorado, which expanded Medicaid under the Affordable Care Act, and Utah, which did not, the authors conclude that expansion may promote the stability of postpartum coverage and increase the use of postpartum outpatient care in the Medicaid program.

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.

Following uninsured patients through Medicaid expansion: ambulatory care use and diagnosed conditions.
The authors assessed ambulatory care use and diagnosed health conditions among a cohort of community health center (CHC) patients uninsured before enactment of the Affordable Care Act (ACA) and followed them after enactment. They found that, post-ACA, 20.9% of patients remained uninsured, 15.0% gained Medicaid, 12.4% gained other insurance, and 51.7% did not have a visit. The authors concluded that a significant percentage of CHC patients remained uninsured; that many who remained uninsured had diagnosed health conditions; and that one-half continued to have three or more visits to CHCs, which continue to be essential providers for uninsured patients.

Development and validation of the Pediatric Medical Complexity Algorithm (PMCA) Version 2.0.
The Pediatric Medical Complexity Algorithm (PMCA) was developed to stratify children by level of medical complexity. The researchers sought to refine PMCA and evaluate its performance based on the duration of eligibility and completeness of Medicaid data. They concluded that PMCA version 2.0 identifies children with C-CD with good sensitivity and very good specificity when applied to Medicaid data.

Outpatient parenteral antimicrobial therapy in pediatric Medicaid enrollees.
The study’s objective was to characterize outpatient parenteral antimicrobial therapy (OPAT) use and clinical outcomes for a large population of pediatric Medicaid enrollees treated with OPAT. It found that ceftriaxone and vancomycin were the most commonly prescribed antimicrobials. An emergency department visit or hospital admission occurred during 38 percent of OPAT episodes, among which 61 percent were OPAT-related.
