ST. PAUL, Minn., Feb. 16, 2015 /PRNewswire/ -- In the past decade, drug overdose deaths have more than doubled and over 50 percent Prime Therapeutics LLCwere related to prescription drugs.1 To help curb this growing epidemic, Prime Therapeutics LLC (Prime) uses a controlled substance (CS) score that identifies high risk CS drug use. Through analysis of the CS score, Prime found a significant association between CS scores and health outcomes (hospitalizations and emergency room visits), CS drug costs, and total cost of care.

"Controlled substance abuse is an ongoing problem in this country," said Cathy Starner, PharmD, BCPS, principal health outcomes researcher for Prime. "We developed our CS score to help health plans identify and intervene with high risk members. Validating the CS score association with health care use and costs helps quantify the potential value of an intervention."

The CS score is determined using three months of a member's CS claims. The score includes the number of CS claims, number of health care professionals who prescribed the CS drugs, number of pharmacies that filled the CS prescriptions, and the rate of CS drug use. For this study, Prime reviewed claims from 11 million commercially insured members. Prime then analyzed a group of nearly 1 million of those members who were continuously enrolled in all of 2012 and 2013 with a CS score of 2.5 or higher (range 2.5 to 21). In terms of health care use and cost, Prime found that a one point increase in CS score is associated with:

  • $1,488 higher total cost of care
  • $235 higher controlled substance drug cost
  • 0.9% increase in hospitalization rate
  • 1.5% increase in emergency room visit rate

Helping doctors spot and stop abuse is an effective way to lower CS scores. Prime's previous research demonstrated a 1.4 point reduction in members' CS scores associated with a prescriber letter intervention.2 Compared to a concurrent control group, this change was statistically significant. This new research suggests that such a letter program could help a 10,000 life insured population potentially avoid $40,800, or about 34 cents per member per month (based on a 0.2 percent member identification rate).

Full results of the study will be presented at the Alliance to Prevent the Abuse of Medicines/U.S. Chamber of Commerce Prescription Drug Abuse Event, Feb. 23 in Washington, D.C. and at Pharmacy Benefit Management Institute's (PBMI) 2015 conference, March 2-4 in San Antonio.
