Severe maternal morbidity and mortality risk at the intersection of rurality, race and ethnicity, and Medicaid.
Using maternal discharge records from childbirth hospitalizations in the HCUP National Inpatient Sample, 2007-15, researchers examined differences in rates of severe maternal morbidity and mortality by rural or urban geography, race and ethnicity, and clinical factors among Medicaid-funded births and privately insured hospital births. The highest rate of severe maternal morbidity and mortality occurred among rural Indigenous Medicaid-funded births; births among Black rural and urban residents and among Hispanic urban residents also experienced elevated rates. The researchers concluded that heightened rates of severe maternal morbidity and mortality among Medicaid-funded births indicate an opportunity for state and federal policy responses to address the maternal health challenges faced by Medicaid beneficiaries, including Black, Indigenous, and rural residents

Risk factors for discontinuation of buprenorphine treatment for opioid use disorders in a multi-state sample of Medicaid enrollees.
The purpose of this study was to examine duration of buprenorphine treatment for opioid use disorder (OUD) following the initiation of treatment in order to identify risk factors for early discontinuation. Researchers analyzed insurance claims from the MarketScan multi-state Medicaid database for 2013 through 2015; their sample included adults aged 18-64 years who had an OUD diagnosis 6 months before initiating buprenorphine treatment. More than 1/4 of the sample discontinued buprenorphine in the first month of treatment, and most of the sample discontinued before 180 days. Risk factors for discontinuation were associated with significantly lower odds of treatment retention for at least 180 days. The study concludes that there is need to implement treatment models that address barriers to treatment retention more effectively.

Suicide after deliberate self-harm in adolescents and young adults.
This study’s objective was to identify risk factors for repeated nonfatal self-harm and suicide death among adolescents and young adults, using a national cohort of patients in the Medicaid program who were followed for up to 1 year after initial self-harm. Data on cause of death was obtained from the National Death Index. The results of the study indicated that adolescents and young adults showed a markedly elevated risk of suicide after nonfatal self-harm. The 12-month suicide standardized mortality rate ratio after self-harm was significantly higher for adolescents than young adults. Hazards of suicide after self-harm were also higher for American Indians and Alaskan natives than for non-Hispanic white patients and for those self-harm patients who initially used violent methods, particularly firearms. The authors conclude that these results underscore the importance of follow-up care to help ensure the safety of self-harm patients.

Hospital characteristics associated with risk-standardized readmission rates.
This national study using Medicare data examined the independent association of 8 hospital characteristics with hospital-wide 30-day risk-standardized readmission rate (RSRR). Overall, larger, urban, academic facilities had modestly higher RSRRs than smaller, suburban, community hospitals, although there was a wide range of performance. The strong regional effect suggests that local practice patterns are an important influence.

Morbid obesity and use of second generation antipsychotics among adolescents in foster care: evidence from Medicaid.
The researchers examined the association between receiving a morbid obesity diagnosis and second generation antipsychotics (SGAs) prescriptions among adolescents in foster care. They found that the risk increases with age. Quetiapine and clozapine increased the risk of a morbid obesity diagnosis more than 2.5 times, and two or more psychotropic drugs (polypharmacy) increased the risk fivefold.

Understanding patient, provider, and system factors related to Medicaid readmissions.
This study was undertaken to understand the complexity of Medicaid readmission issues at the patient, provider, and system levels. It found that significant risk factors for Medicaid readmissions included financial stress, high prevalence of mental health and substance abuse disorders, medication nonadherence, and housing instability. Lacking awareness on Medicaid patients' high risk, a sufficient business case, and proven strategies for reducing readmissions were primary barriers for providers.
