Associations among social needs, health and healthcare utilization, and desire for navigation services among US Medicaid beneficiaries with type 2 diabetes.
The purpose of this study was to determine the number and types of social needs experienced by Medicaid beneficiaries with type 2 diabetes and how these social needs are associated with key health indicators. Findings showed that having more social needs was associated with a wide range of indicators of poor health and well-being. Study participants with the greatest social need burden were most open to intervention.

Disruptions to the patient-provider relationship and patient utilization and outcomes: evidence from Medicaid managed care.
The patient-provider relationship is considered a cornerstone to delivering high-value healthcare. However, in Medicaid managed care settings, disruptions to this relationship are disproportionately common. In this paper, the researcher evaluated the impact of a primary provider's exit from a Medicaid managed care plan on adult beneficiary healthcare utilization and outcomes.

Association of Medicaid managed care drug carve outs with hepatitis C virus prescription use.
The purpose of this cross-sectional study was to explore the relationship between Medicaid-covered Hepatitis C Virus (HCV) medication fills and Medicaid managed care organization (MCO) carve outs of direct-acting antiviral HCV medications. The researchers assessed changes in fills of Medicaid-covered direct-acting antiviral HCV medications in 4 states (Indiana, Michigan, New Hampshire, and West Virginia) that carved out these drugs from Medicaid MCOs between 2015 and 2017. The study found that carve outs were associated with a mean quarterly increase of 22.1 HCV prescriptions per 100 000 Medicaid enrollees. This was a relative increase of 86.3% compared with synthetic control states. Compared with each state's respective synthetic control, HCV prescription fills were associated with an increase of 11.5 HCV prescription fills per 100 000 Medicaid enrollees per quarter in Indiana, 36.6 in Michigan, 20.7 in West Virginia, and 43.6 in New Hampshire. The researchers concluded that carve outs of direct-acting antiviral HCV medications from Medicaid MCO prescription drug coverage were associated with significant increases in HCV medication use.

Effects of forced disruption in Medicaid managed care on children with asthma.
The objective of this study was to evaluate the effect of a forced disruption to Medicaid managed care plans and provider networks on health utilization and outcomes for children with persistent asthma. The investigators concluded that while there was a decrease in the number of outpatient visits associated with forced disruption of Medicaid managed care plans for children with persistent asthma, there were no consistent associations with worse asthma quality performance or higher emergent health care utilization.

Timing of co-occurring chronic conditions in children with neurologic impairment.
Children with neurologic impairment (NI) are at risk for developing co-occurring chronic conditions, increasing their medical complexity and morbidity. In this study, the authors assessed the prevalence and timing of onset for those conditions in children with NI. They concluded that children with NI enrolled in Medicaid had substantial multimorbidity that developed early in life.

Using electronic health records in longitudinal studies: estimating patient attrition.
This study’s objective was to estimate overall and among adults with diabetes or hypertension: 1) patient attrition over a 3-year period at community health centers; and 2) the likelihood that patients with Medicaid switched their primary care source. Data was collected from the retrospective cohort study of 2012-2017 claims data Accelerating Data Value Across a National Community Health Center Network (ADVANCE) Clinical Data Research Network of community health centers. This study focused on Oregon Medicaid enrollees with a total of 232,891 patients aged 19-64 with a gap of 6 months or more following a claim for a visit billed to a primary care source. The authors theorized the reason was due to patients with Medicaid permanently changing their primary care source. They found that attrition over 3 years averaged 33.5% but patients with diabetes or hypertension was lower (25% or less). Among Medicaid patients the attrition rate 12% for community health center patients compared with 39% for single-provider practice patients.

Chronic medication use in children insured by Medicaid: a multistate retrospective cohort study.
This retrospective cohort study examined the use of chronic medication (CM) use in children insured by Medicaid. The cohort included children ages 1 to 18 years from 10 states in 2014. It was grouped by the annual number of CMs (0, 1, 2-4, 5-9, and >=10). Of the over 4.5 million subjects, 18.8% used CMs, and 44% in children with a complex chronic condition. The most common CM therapeutic class was neurologic (28.8%). For children prescribed only 1 CM, the most common class is amphetamine stimulants. For children with 10 or greater CMs prescribed, antiepileptics were the most common. Increased CM use was associated with increased hospitalization and emergency department use.

Medicaid expenditures among children with noncomplex chronic diseases.
This study analyzed Medicaid use by children with noncomplex chronic diseases (NC-CDs). The objective was to describe patient characteristics, expenditures, and use patterns. The researchers used the 2014 Truven Medicaid MarketScan Database to analyze claims from 11 states. Mental health conditions accounted for half of the inpatient diagnosis, with the expenditures high as well. One-percent of children with the highest expenditures accounted for 20% of the total Medicaid expenditures.

Practice style variation in Medicaid and non-Medicaid children with complex chronic conditions undergoing surgery.
With differential payment between Medicaid and Non-Medicaid services, researchers asked whether style-of-practice differs between similar Medicaid and Non-Medicaid children with complex chronic conditions (CCCs) undergoing surgery. They found that treatment style differences between Medicaid and Non-Medicaid children were small, suggesting little disparity with in-hospital surgical care for patients with CCCs operated on within Children's Hospitals.

Medicaid's impact on chronic disease biomarkers: a cohort study of community health center patients.
This study assessed changes in biomarkers of chronic disease among community health center (CHC) patients who gained Medicaid coverage with the Oregon Medicaid expansion (2008-2011). It found that patients with uncontrolled chronic conditions experienced objective health improvements over time. In two of three chronic disease cohorts, those who gained Medicaid coverage were more likely to achieve a controlled measurement than those who remained uninsured.

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.

Service use preceding opioid-related fatality.
The authors analyzed health service patterns before opioid-related death among nonelderly individuals in the Medicaid program, focusing on decedents with and without past-year diagnoses of non-cancer chronic pain. They found that persons dying of opioid-related causes, particularly those who were diagnosed with chronic pain conditions, commonly received services related to drug use disorders and mental disorders in the last year of life, though opioid use disorder diagnoses near the time of death were rare.

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.
