Comparison of Price Index Methods and Drug Price Inflation Estimates for Hepatitis C Virus Medications
The findings of this cross-sectional study indicate that the current product-level methods to estimate drug price inflation underestimated price increases for HCV drugs by failing to include the high launch prices of new market entrants. Using a class-level approach, the index captured higher spending on new products at launch. Prescription-level analyses, which did not consider shorter durations of treatment, overestimated price increases

Covid-19 and Hospital Financial Viability in the US
The results of this cross-sectional study suggest that although hospitals experienced a sizeable reduction in operating margins in 2020, their overall profit margins remained similar to those in prior years, suggesting that the COVID-19 relief fund effectively offset the financial losses for hospitals during the COVID-19 pandemic. Government, rural, and smaller hospitals, which were supported by some targeted fund allocations, generated higher ov…
Charity Care and Community Benefit in Non-Profit Hospitals
Policymakers are using different ways to measure the community benefit provided by non-profit hospitals because different policy makers have different policy objectives. We compare 3 commonly used measures of community benefit; examine the correlation across the 3 measures; examine how the distribution of community benefits varies across non-profit hospitals; and compare the factors associated with the level of community benefit for each definiti…

Untangling the Concepts of Disability, Frailty, and Comorbidity
Three terms are commonly used interchangeably to identify vulnerable older adults: comorbidity, or multiple chronic conditions, frailty, and disability. However, in geriatric medicine, there is a growing consensus that these are distinct clinical entities that are causally related. Each, individually, occurs frequently and has high import clinically. This article provides a narrative review of current understanding of the definitions and distingu…
