To describe the out-of-pocket burden on patients with coinsurance and assess its association with pharmaceutical competition, which increases payers' leverage to seek higher rebates. This retrospective cohort study used branded prescription drugs with US sales reported by publicly traded companies. The study included drugs with nonmissing, nonnegative rebates between 2014 and 2018 from SSR Health. Data analysis was conducted from June to December 2020. Level of branded and generic competition and calendar year. Retail price markup (ie, the ratio of rebate to net price) paid by patients at the point of sale and effective out-of-pocket share (ie, coinsurance multiplied by list price divided by net price) of a standard Part D plan. Trends in these outcomes were examined and then stratified by degree of competition. There were urden for patients paying coinsurance on drug list prices between 2014 and 2018, especially in markets with more pharmaceutical competition. Payers passing rebates through to patients at the point of sale could restore the benefits of competition and rebates. This study found substantial increases in cost-sharing burden for patients paying coinsurance on drug list prices between 2014 and 2018, especially in markets with more pharmaceutical competition. Payers passing rebates through to patients at the point of sale could restore the benefits of competition and rebates.Searching and reading relevant literature is a routine practice in biomedical research. However, it is challenging for a user to design optimal search queries using all the keywords related to a given topic. As such, existing search systems such as PubMed often return suboptimal results. Several computational methods have been proposed as an effective alternati
