What is Value-based Drug Pricing?

 

The U.S. pays more for prescription drugs than any other country:

Drug prices also outpace general inflation. Between 2015 and 2016, pharmaceutical prices climbed 9.8 percent, while food and alcohol increased only 2.8 percent and clothing 5.7 percent.

The causes of high drug prices are complex, spanning patent law, third-party administration of pharmacies and lack of Medicare negotiation. Another key cost driver can be found in the relationship between price and value. For example, one treatment for Hepatitis C can run $1,000 per pill, despite controversy about its advantages over cheaper alternatives as well as its safety for patients coinfected with Hepatitis B.

Value-based pricing (VBP) of drugs is a proposed solution to these current challenges in drug affordability. An alternative to current payment models like fee for service (FFS), VBP is designed to improve accountability for treatments and align patient/plan payments accordingly.

Creating a model for value-based drug

pricing

The main question for VBP is how do we precisely define and measure “value”?  A basic definition might include a medication’s usefulness in resolving and/or controlling the conditions for which it is indicated. However, measurement of these results can be challenging.

The specific process will differ from one drug to the next, based on the duration of each drug’s treatment cycle and the demographics of its treated population. Stakeholders will have to make pivotal decisions about what data sources to use, what prices to use as benchmarks and how generics will affect their assessments of cost-effectiveness:

  • Different data sources can yield disparate results for the same treatment. Consider that  drug trial participants are often healthier and younger than real-world patients, and as such the two populations might respond differently.
  • Drug list prices are publicly available, but they are often much higher than what any insurer will ever actually pay. Information on the latter may be more useful for benchmarking purposes.
  • Generics cost less than original brands. The entry of less expensive medications could dramatically improve a substance’s cost-effectiveness, even if its efficacy stays the same, muddling any attempt at VBP study.

As we can see, assessing value is not always straightforward. Indeed, two separate value models for the asthma medication Omalizumab yielded conflicting results about the drug’s cost/benefit tradeoffs. What steps can be taken to produce clearer answers about drug value for VBP?

A viable model would evaluate drugs that have measurable outcomes (i.e., their use can be clearly tied to changes in indicated condition) and no generic alternatives (so that results reflect, as much as possible, efficacy instead of economy). Other ideal conditions for modeled VBP assessment include a competitive market with branded alternatives, a high potential sales volume and questions or concerns over efficacy that VBP could possibly resolve.

Current initiatives in VBP: What is in the works, and what challenges remain

 

The push for widespread, standardized VBP has gotten a recent boost from industry heavyweights such as the American Medical Association, which has endorsed it as a reprieve from “carte blanche” drug pricing. Payers have also set up value-based contracts with pharmaceutical makers to put VBP into practice:

  • Harvard Pilgrim and Amgen entered one such agreement for Repatha, a drug for treating cholesterol, under which the latter agreed to provide rebates to the former if  the medication did not meet predefined performance thresholds. For reference, Repatha costs more than $14,000 per year.
  • Cigna and Merck have also set up similar frameworks for the diabetes drugs Januvia and Janumet.
  • A May 2017 survey of health plans by Avalere found that 30 percent of them had one or more such contracts in the works.

 

Going forward, treatments for diabetes, high cholesterol and cancer, which should yield measurable results, are seen as prime candidates for these sorts of agreements. Value-based contracts could become widely adopted as part of a larger move to value-based reimbursement, the alternative to FFS that KPMG estimated was in use in half of U.S. health systems as of early 2017.

Granted, there are significant obstacles to VBP, including the challenges of establishing value and the complications of the “best price” rules of Medicaid, which help reduce federal spending
on drugs by billions each year. But a balance can likely be struck by payers and manufacturers as they forge partnerships to address VBP.

To that end, pharmacy benefit management (PBM) and drug utilization reviews (DUR) could be valuable tools for establishing VBP, as they aim to assess the value, necessity and appropriateness of prescription treatments. Healthcare organizations like Advanced Medical Reviews (AMR), an independent review organization, are one avenue for providing Group Health plans with a team of qualified specialists and physicians to examine the value of its non-formulary drugs. Whether through a PBM or DUR, these processes commonly involve a committee of physicians, nurse practitioners and pharmacists that review patient prescription data to make informed decisions accounting for issues such as interaction of multiple medications, over-prescription and appropriate opiate use.

Dan Perlow, VP of Enterprise Accounts at AMR, explains, “AMR can offer the bridge between best price and value with our expert panel of reviewers whose clinical judgment can shed insight into the areas of critical concern. A good example is a Hep C drug like Harvoni, as it is expensive, but extremely effective in a specific population over a shorter period of time compared to other similar medications. The challenge is that pricing for these drugs can be misleading. The actual price may vary greatly from the list price. Not only do different insurance companies negotiate separately with the manufacturer, but also manufacturer coupons and assistance from various foundations can affect the final price. Ultimately, curing Hepatitis C will save the healthcare system over time far more than the cost of the medications.”

All of these considerations figure into AMR’s reviews and how healthcare, as an industry, addresses the price of drugs. Concrete processes, such as PBM or DURs, ultimately support VBP and they support ensuring patients receive appropriate and quality healthcare.

As the cost of healthcare is addressed from multiple angles- healthcare reform, prescription drug cost and the adoption of new technology- tying cost to the treatment’s value to the patient will be an increasing part of every solution. How value is assessed and costs are determined may continue to be the challenging part of this new approach, but there is hope that continued collaboration between payers and providers will expand access to affordable and quality health care.
