Medicines Use and Spending in the U.S.
A Review of 2016 and Outlook to 2021
About the Report
In this report we highlight various aspects of the market for medicines in the U.S—spanning aggregate spending, key medicine categories, volumes, patient cost exposure, as well as our outlook to 2021. The report seeks to provide appropriate context and perspective around the complex factors that drive the level of spending on medicines and their role in our healthcare system.
Spending on medicines totaled $450Bn in 2016, growing at less than half the rate seen in the last two years, based on invoice prices. Net spending was $323Bn, up 4.8% over 2015 levels, after adjusting for estimated rebates and other price concessions by manufacturers. In 2016, fewer than half the new medicines launched than in the prior two years, and this was coupled to a reduced level of spending on new medicines.
The usage of medicines by patients has continued to rise, in part due to many more patients having wider access to insurance and low cost generic medicines. However, a minority of patients still face substantial out-of-pocket costs and experience a dramatically different trend in their spending on medicines than other patients and the system overall.
The outlook for medicine spending through 2021 is for mid-single digit growth driven by further clusters of innovative treatments, offset by a rising impact from brands facing generic or biosimilar competition. Drug manufacturer responses to heightened market competition and scrutiny of drug pricing are expected to result in more modest levels of invoice (and net) price growth in the forecast period.
U.S. Medicines Growth Slowed by Half in 2016 to 4.8% on a Net Basis
- Spending grew 4.8% net of off-invoice discounts and rebates, as invoice-level growth slowed to 5.8%.
- Discounts, rebates and other price concessions on brands reduced absolute invoice spending by an estimated 28% to $323.1 billion
- Spending growth slowed in 2016 after two historically high years due to lower price increases for protected branded products, fewer new products launched and lower spending growth, specifically for hepatitis C treatments where spending declined in 2016.
- Net price increases averaged 3.5%, significantly lower than invoice price increases which averaged 9.2%, with 62% of growth from price on an invoice basis conceded after estimating net prices.
Real Net Per Capita Drug Spend Has Been Relatively Unchanged Over the Past Decade
- Medicine spending including both pharmacy and medicines dispensed in hospitals, clinics and other non-retail settings, has increased an average of 1.1% per year since 2006 when it was $805 per person, and has risen only 11% in ten years to $895 in 2016.
- Spending increased 5.8% in 2016 on an invoice basis and 4.8% on a net basis, but after accounting for population, economic growth and estimates of off-invoice concessions by manufacturers, spending increased 2.6% over the prior year.
- While manufacturer net revenues, adjusted in this way, have increased only modestly over the past decade, patient exposure to costs has increased dramatically, more in line with list prices.
Net Prices Continued to Increase More Slowly Than Invoice Prices
- Price increases for protected brands averaged 9.2% on an invoice-price basis while net price growth is estimated to have increased 3.5% in 2016 on average.
- Net price spending growth was driven by autoimmune, HIV and oncologic therapies while offset by large net price declines in hepatitis, MS and respiratory therapies.
- The increase in average net price growth from 2015 to 2016 reflects changes in the portfolio of large brands in the market and differential levels of price concessions.
- Invoice price increases were lower than prior years on average, but above average increases were observed in many individual markets and had the most impact on invoice-level spending in autoimmune, cholesterol, nervous system disorders (e.g., epilepsy, Parkinson’s), and erectile dysfunction.
Prescription Growth in Younger Patients is Driven by Usage, While Growth in Older Patients is Due to Population
- Patients over 65 had declining per capita usage of prescriptions from 2011 to 2016 while driving most of the population growth in the country as “baby boomers” reached retirement age and many continue to live longer.
- Adults aged 26-64 accounted for 99% of the 402Mn of incremental prescriptions from rising per capita usage, as both groups benefited significantly from Medicaid expansion and insurance exchanges under the ACA.
- Overall, the aging population is driving higher prescription usage. This is mainly occurring through population growth, with patients over 50 accounting for 682Mn of the 884Mn incremental prescriptions over the past five years, 70% of that from a rising share of the population, and 30% from higher usage, all from the 50-64 age group. Patients over 65 had declining usage.
Prescriptions Dispensed at Zero Patient Out-of-Pocket Cost Reached Thirty Percent in 2016
- 29.9% of prescriptions have been dispensed at zero patient out-of-pocket cost, including brands and generics, up 1.5% since 2015, all due to increased use of zero cost generics.
- The total share of prescriptions where patients paid some amount less than $50 declined by 1.3% to 67.8% in 2016.
- The proportion of claims with patient cost exposure greater than $50 increased also declined slightly from 2.5% to 2.3% in 2016.
Since 2013, Average Out-of-Pocket Costs for All Brand and Generic Prescriptions has Decreased by $1.19
- Average patient out of pocket costs declined from $9.66 in 2013 to $8.47 in 2016, with 2016 brand costs declining to $28.31 from $32.36 in 2013 and generics dipping to $5.54 from a high of $6.05 in 2013.
- The list prices of brands continue to be far higher than the average paid by patients, as few patients are exposed to those costs in their insurance plans.
- The average list price for brands averaged 12 times higher than the average out of pocket cost for patients in 2016 compared to 3 times higher for generics.
