  3. 1Define and Characterize Diversion

  4. Definition of Diversion “The transfer of a controlled substance from a lawful to an unlawful channel of distribution or use.” Section 309, Diversion Prevention and Control Uniform Controlled Substances Act National Conference of Commissioners on Uniform State Laws, 1994 “means manufacture, possession,delivery or use of a controlled substance by a person or in a manner not specifically authorized by law.” Section 3302.(12) of the New York State Public Health Law

  5. Diversion Examples Diversion Sharing Selling, buying Stealing Prescription forgery Doctor shopping Illegal internet Rx Criminal prescribing Not Diversion Using your own legitimately prescribed medication to get high (~20% of NMU)

  6. 2What is Known About Sources of Diverted Prescription Opioids

  7. Source of Pain Relievers by Past Year Users Aged ≥12: 2006 Totals may not =100% because of rounding or because suppressed estimates not shown “Other” includes: “Wrote fake prescription,” “Stole from doctor’s office/clinic/hospital/pharmacy,” & “Some other way. 68% from docs

  8. 5 Most Common Sources of Misused Prescription Opioids: By Population Percentage *For free & bought; †Own prescription, 1 doctor, & >1 doctor ‡Stolen, stole from friend/family, theft, & forged prescription

  9. Sources of Diverted Dosage Units Distribution System Primary Diversion 2007 Total Doses Manufacturers Theft from Manufacturers 3,251,539 Distributors Theft from Distributors 706,558 2,633,098 Pharmacies Theft from Pharmacies Hospitals/Clinics Theft from Hospitals/Clinics ?

  10. Criminal Prescribing: 1 case “The board investigator presented evidence that Brown was the single leading prescriber of OxyContin in the entire state, with his prescriptions accounting for 288,859 of the 922,985 OxyContin tablets sold through pharmacies in 2004.” For a 30-month period, Brown was the state's second largest prescriber of OxyContin

  11. Schedule II Opioid Rx Dispensed to Individuals Showing Questionable Activity* 6 5 4 63,000 scripts Estimated percentage 3 3.5 million doses 2 1 0 96 98 99 00 01 02 03 04 05 97 Fiscal yr *Questionable activity = obtained Schedule II opioid prescriptions from ≥4 pharmacies & ≥4 physicians during the specified yr

  12. Quantifying Diversion: Research Agenda Clean up NSDUH data: Break down “non-medical use” data How many dosage units ingested How many dosage units acquired through different sources* Update drug picture cards Clean up DEA Form 106 Database Compile Internet diversion data Compile criminal prescribing data; validate algorithms for identifying criminal prescribing Compile doctor shopping data; validate algorithms for identifying inappropriate doctor shopping

  13. 3Speculate About the Role of Dentists in Prescription Opioid Diversion

  14. Top SpecialtiesPrescribing Immediate-Release Opioids,1998 vs. 2002(WITH Hydrocodone & Oxycodone Combination Products) 2002 1998 Dentists likely prescribe about a billion doses per year of opioids, mostly immediate-release combination products 14 • Source: IMS Health, National Prescription Audit PlusTM, Year 1998 to 2002, Excluding Long-Term Care & Mail Order Channels, Data Extracted August 2003.

  15. Speculations About Role of Dentists in Prescription Opioid Diversion • Dentists prescribe large volumes of drugs most commonly abused by adolescents and others • The extent to which opioids are prescribed in greater quantities than necessary is unknown but probably considerable • Anecdotal evidence suggests that adolescents use opioids non-medically that they or family members obtain from dentists • Dentists rarely screen for opioid abuse risk factors or doctor shopping, monitor pts, educate them on risks of controlled substances or med storage/disposal, etc. • It is not clear how well dentists understand the basic pharmacotherapy of pain and the appropriate role of opioids

  16. 4Potential Solutions

  17. FDA, Opioids, and REMS FDAAA September 2007 RISK EVALUATION AND MITIGATION STRATEGIES (REMS) REQUIREMENTS Title IX, Subtitle A, Section 901 of the Food and Drug Administration Amendments Act of 2007 (FDAAA) amends the Federal Food, Drug, and Cosmetic Act (FDCA) to authorize FDA to require the submission of a REMS for an approved drug if FDA becomes aware of new safety information and determines that such a strategy is necessary to ensure that the benefits of the drug outweigh the risks (section 505-1(a)). This provision took effect on March 25, 2008.
