Health Policy Experts Voice Ways to Tame Rising Drug Costs, Protect Patients

Allison Inserro

Health policy experts laid out a series of proposals to bring down prescription drug costs, lower US healthcare spending, and protect patients in a series of 3 papers published recently as Health Affairs Policy Options Papers.

The papers, supported by the Commonwealth Fund, advocate for increasing competition, applying value-based purchasing, and protecting patients from high out-of-pocket costs.

The first 2 papers—one by Jonathan J. Darrow and Aaron S. Kesselheim, MD, JD, MPH; and the other by Steven D. Pearson, MD, and co-authors—propose 5 ways to increase competition, both among brand name manufacturers and through lower-cost generic drugs: In addition, Darrow and Kesselheim1 argue for Medicare, Medicaid, and other government payers to exclude coverage of low-value drugs altogether.

Pearson et al2 further propose allowing the government to make patent protection and other forms of market exclusivity for drugs contingent on manufacturers fairly pricing their products. Under such a system, higher-value drugs would be rewarded with longer periods of protection from competitors. They propose 4 additional ways to use value-based purchasing: The third paper, by Stacie Dusetzina, PhD, and colleagues,3 looked at how high prescription drug prices and a shift toward higher cost sharing by insurers interfere with the care of patients who need expensive specialty drugs. Both commercial insurers and Medicare Part D have moved away from co-payments and toward both coinsurance (where the patient pays a percentage of the drug’s total price) and higher deductibles.

However, when out-of-pocket costs become unaffordable, patients may stop taking necessary medicine. The authors propose instead that insurers charge co-payments for specialty drugs, rather than coinsurance.

Coinsurance is intended to make patients more cost sensitive, so they will “shop around” for better value. Coinsurance, however, serves little economic purpose in a market where patients cannot compare pricing because only 1 manufacturer sells each specialty drug.

Insurers also could give patients incentives to choose high-value drugs, perhaps by exempting them from deductibles or allowing lower cost sharing.

Policy makers could impose a limit on how much Medicare beneficiaries with Part D plans must spend out of pocket on prescription drugs.
