Employers continue to struggle with controlling rising health care costs and providing employees with affordable and quality care options. Of particular concern is the high costs associated with specialty drugs. The specialty drug industry has grown from a few available drugs in the 1990s to more than 300 specialty drugs today. For most employer-sponsored health plans, the cost of specialty drugs is their fastest-growing expense. As these treatments become more widely available, employers will likely be forced to address even higher specialty drug costs.
