ST. LOUIS, April 22, 2013 /PRNewswire/ -- Express Scripts' (NASDAQ: ESRX) industry-leading prescription management programs drove down utilization of prescription drugs for workers' compensation payers last year even though overall drug trend rose, according to new research released today in the Express Scripts 2012 Workers' Compensation Drug Trend Report. (Logo: http://photos.prnewswire.com/prnh/20080827/EXPRESSSCRIPTSLOGO) Narcotic analgesics, which once again accounted for the highest spend among therapy classes in workers' compensation, saw utilization decline 2.7 percent. OxyContin ®, which accounted for nearly 10 percent of the total drug spend, had a 6.1 percent drop in utilization, although at $132.50, it still represents the highest average cost per user. Overall trend — a combination of spending on drugs and utilization of drugs — increased 2.9 percent in 2012, reversing two years of declines, driven primarily by a 10 percent increase in cost per user for antidepressants and dermatologicals, such as Lidoderm™, Flector™ and Voltaren™. Availability of new products or new product indications in the two classes greatly affected trend. Tim Pokorney, pharmacist, and clinical director of workers' compensation at Express Scripts, noted that the findings demonstrate the need for effective prescription-drug management programs for workers' compensation payers. "Payers need innovative solutions that help them drive the use of clinically equivalent, cost-effective generics that can help rein in their overall pharmacy spending," Pokorney said. "Express Scripts is uniquely positioned to offer payers better solutions by bringing together our complementary capabilities of the behavioral sciences, clinical specialization and actionable data." Programs that help control utilization include Oral Fentanyl Intervention and Long-Acting Narcotics outreach to physicians. Express Scripts also offers step therapy, narcotics education for injured workers and physicians, Drug Utilization Review, Physician Peer-to-Peer, and formulary management programs. One product that helps manage trend for clients is a communication program that encourages injured workers to use lower-cost generic equivalents. The product is based on the findings of an Express Scripts research pilot which demonstrated how injured workers who received a letter explaining how their prescription drug choices could help control the rising cost of healthcare were 60% more likely to choose a generic equivalent.
