This paper examines the issue of prices, relative to value, for cancer drugs. The analysis focuses on the effects on manufacturer pricing incentives of insurance coverage, specifically, the effectiveness of patient cost sharing, incentives created by reimbursement rules for physician-dispensed drugs, and payer ability and incentives to negotiate discounts. For pharmacy-dispensed cancer drugs, both Medicare Part D prescription drug plans (PDPs) and private payers' pharmacy benefit managers are increasingly placing these drugs on specialty tiers that offer no leverage for negotiating discounts and imply often unaffordable cost sharing for patients who lack catastrophic coverage. Simulation analysis of financial risks faced by PDPs confirms their incentives to place costly drugs on specialty tiers if more preferred formulary placement would increase use, possibly because of adverse selection risk. Faced with largely price-insensitive consumers and payers, manufacturers would rationally charge high prices. This situation is exacerbated for physician-dispensed cancer drugs, where Medicare's average selling price plus 6% reimbursement rule favors high-priced drugs. Because U.S. payers do not require evidence on prices relative to value, U.S. data are unavailable to test whether prices are higher, relative to value, for cancer drugs than for other drugs. Evidence from the Canadian Common Drug Review on cost-utility values suggests that cancer drugs are relatively high priced, although conclusions are tentative because of very small samples and non-U.S. data. Making such outcomes-adjusted prices available in the U.S. would be helpful to physicians, payers, and patients and indirectly constrain pricing to align with value.

Drug overdoses involving opioid analgesics have increased dramatically since 1999, representing one of the United States' top public health crises. Opioids have legitimate medical functions, but improving access may increase abuse rates even among those not prescribed the drugs given that opioids are frequently diverted to nonmedical use. We have little evidence about the causal relationship between increased medical access to opioids and spillovers resulting in abuse. We use the introduction of the Medicare Prescription Drug Benefit Program (Part D) as a large and differential shock to the geographic supply of opioids. We compare growth in opioid supply and abuse rates in states with large 65+ population shares to states with smaller elderly population shares with a focus on abuse among the Medicare-ineligible population. Part D increased opioid utilization for the 65+ population, and we show that this increase in utilization led to significant growth in the overall supply of opioids in high elderly share states relative to low elderly share states. This relative expansion in opioid supply resulted in an escalation in opioid-related substance abuse treatment admissions and opioid-related mortality among the Medicare-ineligible population, implying meaningful spillovers to individuals who did not experience any change in prescription drug benefits. The evidence suggests that increased opioid supply is associated with economically-important levels of diversion for nonmedical purposes. Our estimates imply that a 10% increase in medical opioid distribution leads to a 7.4% increase in opioid-related deaths and a 14.1% increase in substance abuse treatment admission rates for the Medicare-ineligible population.
The toxicity and solubility of chromium(VI) can be decreased by certain microbes that reduce chromium(VI) to chromium(III). However, these bacteria do not escape unscathed from this process. Chromium(VI) reduction damages the essential macromolecules of living systems. Trehalose protects organisms from chemical stress but has not been tested in the context of bioremediation. We engineered bacteria to produce trehalose and found that they then reduced 1 mM chromium(VI) to chromium(III), whereas wild-type cells were only able to reduce half that amount. Thus, by providing bacteria with a biochemical defense against the side-effects of chromate reduction may be a new approach to cleaning up sites that are contaminated with high levels of chromate.
Wellness programs can be grouped into distinct configurations, which have different workplace health focuses. Although monetary incentives can be effective in improving employee participation, the magnitude and significance of the effect is greater for some program configurations than others.
Industry or regional characteristics are likely determinants of incentive use for wellness programs. Penalties appear to be effective, but attention should be paid to what types of employees they affect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
