The impact of health insurance expansion on physician treatment choice: Medicare Part D and physician prescribing.
Researchers tested the effect of the introduction of Medicare Part D on physician prescribing behavior using data on physician visits from the National Ambulatory Medical Care Survey (NAMCS). Subjects were patients aged 60-69. The researchers found a 32% increase in the number of prescription drugs prescribed or continued per visit and a 46% increase in the number of generic drugs prescribed or continued for the elderly after the introduction of Medicare Part D.

Price elasticity of demand for buprenorphine/naloxone prescriptions.
In this study, using the IBM MarketScan(R) Commercial Claims and Encounters Database for individuals with employer-sponsored private health insurance coverage, the researchers examined the relationship between cost sharing and the number of buprenorphine/naloxone prescription fills using enrollee-level longitudinal fixed effects models.

Quality measures for managing prescription of antipsychotic medication among youths: factors associated with health plan performance.
This study examined the performance of health plans on two Healthcare Effectiveness Data and Information Set (HEDIS) measures: metabolic monitoring of children and adolescents prescribed an antipsychotic and use of first-line psychosocial care for children and adolescents prescribed an antipsychotic for a nonindicated use. This study then identified key plan characteristics and other contextual factors associated with health plan performance on quality measures related to pediatric antipsychotic prescribing. Findings suggested that quality measures, in conjunction with policies such as prior authorization, can encourage better care delivery to vulnerable populations.

Prescription opioid use patterns, use disorder diagnoses and addiction treatment receipt after the 2014 Medicaid expansion in Oregon.
This study compared the prevalence of receipt of opioid prescriptions and opioid use disorder (OUD), along with time from OUD diagnosis to medication-assisted treatment (MAT) receipt between Oregon residents who had been continuously insured by Medicaid, were newly insured after Medicaid expansion in 2014 or returned to Medicaid coverage after expansion.

Public insurance expansions and smoking cessation medications.
The authors examined public insurance expansion on use of smoking cessation medications. The Affordable Care Act expanded coverage of these medications with financing with Medicaid. Data was analyzed from retail and online pharmacies from 2011 to 2017, and the expansion increased smoking cessation prescriptions by 24% in new medication use.

Out-of-pocket costs are on the rise for commonly prescribed neurologic medications.
The purpose of this study was to determine out-of-pocket costs for neurologic medications in 5 common neurologic diseases. The investigators concluded that out-of-pocket costs for neurologic medications have increased considerably over the last 12 years, particularly for those in high-deductible health plans. Out-of-pocket costs vary widely both across and within conditions. They assert that to minimize patient financial burden, neurologists require access to precise cost information when making treatment decisions.

Racial and ethnic disparities in medication adherence among privately insured patients in the United States.
The purpose of this study was to examine the association between socioeconomic status (SES) and racial and ethnic disparities in medication adherence for three widely prescribed therapeutic classes. The investigators concluded that racial/ethnic disparities in adherence were mitigated, but persisted after controlling for detailed socioeconomic measures. They suggest that interventions should focus more on improving medication adherence of existing users, particularly in treating asymptomatic conditions.

Buprenorphine coverage in the Medicare Part D program for 2007 to 2018.
This letter discusses a study which looked into coverage of buprenorphine for opioid use disorder (OUP) with Medicare. The majority of plans do cover the generic version. However, the number of plans which require previous authorization has increased over from 2007 to 2018. This may hamper treatment by primary care physicians.

Appropriateness of outpatient antibiotic prescribing among privately insured US patients: ICD-10-CM based cross sectional study.
This study used ICD-10 codes to determine the appropriateness of outpatient antibiotic prescriptions filled in privately insured patients in the US. Determinations were made based on diagnosis whether the prescriptions were “appropriate”, “potentially appropriate”, “inappropriate”, or no diagnosis code found. Among a cohort of over 19 million, only 12.8% were deemed appropriate, 23.2% were inappropriate, 35.5% potentially inappropriate, and 28.% not associated with a diagnosis code.

The effect of health insurance on prescription drug use among low-income adults: evidence from recent Medicaid expansions.
This study examined how subsidized coverage affected prescription drug utilization among low-income non-elderly adults. Among other results, the investigators found that within the first 15 months of new health insurance availability, aggregate Medicaid-paid prescriptions increased 19 percent, amounting to nearly 9 new prescriptions a year, per new enrollee. They also found no evidence of reductions in uninsured or privately-insured prescriptions, suggesting that new coverage did not simply substitute for other payment sources.
