Driven by Surging Prices, Patient Spend on Insulin Nearly Doubles Over 5 Years

Spending on insulin in the United States per patient nearly doubled over a 5-year period, driven primarily by price hikes that encompassed all insulin products and types, according to new data published by the Health Care Cost Institute (HCCI).1
 
Insulin affordability has increasingly become a serious concern as list prices for these life-saving medications continue to surge. The report investigated trends in health care spending on individuals with type 1 diabetes between 2012 and 2016.
 
Prescription drug prices have been under increasing scrutiny amid growing pressure from lawmakers. A House Committee recently sent letters to 12 drug companies seeking information on prescription drug pricing practices, promising to launch an investigation into price hikes. These companies included the top 3 insulin manufacturers: Eli Lilly, Novo Nordisk A/S, and Sanofi SA.2 
 
For the report, researchers analyzed commercial claims data for approximately 15,000 patients with type 1 diabetes annually who had at least 1 prescription for an insulin product during the year. They examined gross per-person spending by type of service–inpatient, outpatient, professional procedure, insulin, and non-insulin pharmacy–over 2012 to 2016. According to the data, insulin had the largest increase in gross spending across all categories, accounting for nearly half of the increase in total per-person spending over the 5-year period.1
 
Between 2012 and 2016, gross insulin spending per person increased by $2841, based on the data. In 2016, individuals with type 1 diabetes spent $5705 per person on insulin. The report also found that average daily insulin use by those with type 1 diabetes rose by just 3%. Despite this, prices increased steadily for all insulin products between 2012 and 2016, with the average point-of-sale price nearly doubling from $0.13 per unit to $0.25 per unit. According to the report, this price increase translates to a jump from $7.80 per day in 2012 to $15 per day in 2016 for someone using an average amount of insulin.1
 
The analysis also highlighted utilization trends among different insulin products over the time period. According to the findings, daily use of Humalog increased while Novolog decreased. Among basal insulins, daily use of Lantus/Toujeo declined, which was offset by an increase in use of Levemir and the adoption of Tresiba, which came to market in 2015.1
 
Price changes occurred in all products, indicating that increased spending was driven mostly by higher prices overall and not just a shift toward newer, more expensive insulins, the report concluded.
 
HCCI noted that the prices in the analysis do not reflect manufacturer rebates and coupons. To explore how this may affect spending, they included a case where rebates and coupons offset 50% of the gross cost of insulin each year. According to the report, the net increase in total spending per person would be $4606, with a $1421 increase in insulin spending. The report concluded the example indicates that spending on insulin would still be the largest out of the spending categories.1  
 
A previous white paper published by the American Diabetes Association Insulin Access and Affordability Working Group pointed to a need for more transparency in the insulin supply chain. The group noted that the complexity of the system is a concern due to the variety of stakeholders involved and the multiple transactions that occur between them. Overall, they recommended that providers and pharmacists communicate openly with patients regarding insulin costs and suggested that providers prescribe the lower price insulin required to effectively and safely achieve treatment goals.3
