Patient Out-of-Pocket Costs for Biologic Drugs After Biosimilar Competition.

Importance: Biologic drugs account for a growing share of US pharmaceutical spending. Competition from follow-on biosimilar products (subsequent versions that have no clinically meaningful differences from the original biologic) has led to modest reductions in US health care spending, but these savings may not translate to lower out-of-pocket (OOP) costs for patients.

Objective: To investigate whether biosimilar competition is associated with lower OOP spending for patients using biologics.

Patient Out-of-Pocket Costs Following the Availability of Biosimilar Versions of Infliximab.

After market exclusivity ends for biologic drugs, biosimilars-follow-on versions made by other manufacturers-can compete with lower prices. Biosimilars have modestly reduced prescription drug spending for US payers, but it is unclear whether patients have directly experienced any savings. In this study we assessed whether availability of biosimilar infliximab was associated with lower out-of-pocket (OOP) costs, using claims from a national data set of commercially insured patients from 2014 to 2018.

Hysteretic device characteristics indicate cardiac contractile state for guiding mechanical circulatory support device use.

Background: Acute heart failure and cardiogenic shock remain highly morbid conditions despite prompt medical therapy in critical care settings. Mechanical circulatory support (MCS) is a promising therapy for these patients, yet remains managed with open-loop control. Continuous measure of cardiac function would support and optimize MCS deployment and weaning.
