Prescription Pain Medication DiversionPrescription Pain Medication Diversion

Event:A. Increased prescribing of opioids for pain

Event:A. Increasing reports of non-medical use

Causal Attribution:A. Diversion is due primarily to increased availability

to patients for pain managementB. Prescribers and patients are to blame

– Increased stigmatization

C. Safety of prescription opioids is questionedFallacyFallacy

Prescription Pain Medication DiversionPrescription Pain Medication Diversion

Increased monitoring of prescribersTightening prescription requirements

Imposing undue limits on legitimate prescribing

Increased scrutiny of patientsPublicize risks of pain medicines

But...

What if there are non-medical diversion sources?

If attribution is correct,Then the main solutions are:

ConclusionsConclusions

Medical use of pain medications has increased contemporaneously with non-medical use, with little understanding of the relationship

Efforts to reduce pain medication abuse and diversion historically has focused on the prescriber/patient relationship

A comprehensive approach has been slow to come

The U.S. government has recently issued a comprehensive strategy to reduce abuse/diversion

More evidence is needed to guide interventions

Action Steps:A Critical Need for More Information

Action Steps:A Critical Need for More Information

Target multiple sources of diversion Are there non-medical diversion sources? Is diversion only/mostly the result of increased prescribing

for pain?

Quantify amounts diverted and motivations for use

Evaluate effectiveness of interventions attempted Improving prescribing and dispensing practices Improving monitoring and coordination Improving treatment of people who use non-medically Limit adverse impact on medical availability

Epidemiological understanding
