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.

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.

Multimorbidity and COPD Medication receipt among Medicaid beneficiaries with newly diagnosed COPD.
The aim of this study was to examine the association between multimorbidity and chronic obstructive pulmonary disease ( COPD) medication receipt among Medicaid beneficiaries with newly diagnosed COPD. It found that in this group 81.9 percen had at least one co-occurring chronic condition. After controlling for subject characteristics, adults with multimorbidity were less likely to receive COPD medications compared with those without any inflammation-related multimorbidity.

Racial disparities across provider specialties in opioid prescriptions dispensed to Medicaid beneficiaries with chronic noncancer pain.
The purpose of this study was to examine differences across providers’ specialties in prescriptions filled by white and black Medicaid beneficiaries with chronic noncancer pain (CNCP). It found that race-based differences in beneficiaries’ dispensed opioid prescriptions were more prominent among patients of specialists in obstetrics and gynecology and internal medicine, as well as general practitioners/family medicine physicians.

Do medical homes increase medication adherence for persons with multiple chronic conditions?
The goal of this study was to assess the association between medical homes and adherence to newly initiated medications among Medicaid enrollees with multiple chronic conditions (MCC). The researchers examined data from North Carolina Medicaid enrollees with MCC and found that adherence to new medications is greater for those enrolled in medical homes.
