  We examined 3,046,538 acute respiratory infection (ARI) encounters with 6,103 national telehealth physicians from January 2019 to October 2021. The antibiotic prescribing rates were 44% for all ARIs; 46% were antibiotic appropriate; 65% were potentially appropriate; 19% resulted from inappropriate diagnoses; and 10% were related to coronavirus disease 2019 (COVID-19) diagnosis.

• Cancer Drug Trastuzumab And Its Biosimilars Compete On Price For Market Share

  Using Medicare claims, we documented US prescribing patterns for originator biologic trastuzumab (Herceptin), a targeted cancer therapy, and five biosimilar entrants since 2019. The first biosimilar captured a dominant share, but over time, average sales prices of all products declined, and later entrants became dominant in some states. Despite strong brand loyalty to the first biosimilar, competitive pressure increased with subsequent entrants.

• Reforming the Medicare Part D Benefit Design: Financial Implications for Beneficiaries, Private Plans, Drug Manufacturers, and the Federal Government

  Journal of Health Politics Policy and Law · 2022-07-14

  articleOpen access

  CONTEXT: Reforming the Medicare Part D program-which provides prescription drug coverage to 49 million beneficiaries-has emerged as a key policy priority. METHODS: The authors evaluate prescription drug claims from a 100% sample of Medicare Part D beneficiaries to evaluate the current spending distribution across different payers for different types of beneficiaries across different benefit phases. They then model how these estimates would change under a proposal to redesign the Medicare Part D standard benefit. FINDINGS: Spending patterns differ for beneficiaries who do and do not qualify for low-income subsidies. Part D plans face limited liability for total spending under the current standard benefit design, amounting to 36% of total spending for beneficiaries who do not receive low-income subsidies and 28% of total spending for those who do. Proposed reforms would increase plan liability and significantly change the distribution of liability across plans, drug manufacturers, and the federal government. CONCLUSIONS: Though the original goal of the Part D program was to create a market of competing private plans that provide prescription drug coverage to Medicare beneficiaries, the standard benefit design that was included in the original legislation reflected significant political compromises. Reforming the standard benefit design to give plans more skin in the game could significantly affect competition in the market, with differential impact across drug classes and types of beneficiaries.
