Learning objectives
• Understand the etiology & consequences of the U.S. prescription opioid epidemic.
• Understand rationale for & methods to:
• Risk assess patients prior to treating pain with opioid medications.
• Monitor benefit & risk associated with pain management using opioid medications.
• Refer or discontinue opioid medications.

Where are all these meds coming from?•Legitimate Provider Rxs (acute &
chronic pain): •common source misused/diverted opioids
•Doctor shopping:•Drug Users
•~ 0.7% of pts legitimately prescribed opioids.
•a/w ↑ mortality. •Drug dealers also obtain Rx’s from physicians.
•Opioid Rx’s from ED & Day surgery (incl. Dental & Podiatry) for acute pain- major source

• 30% Tennessee population filled opioid Rx each year.

Wait, wait…. How did we get here?• Historically, under-treatment of disorders appropriate for opioid
therapy: cancer pain, pain at the end-of-life, & acute pain
• Small, non-RCT studies of safety & efficacy of opioids for chronic non-cancer pain (CNP) suggesting
moderate effectiveness.• Treatment of pain in general prioritized (5th Vital sign: American
Pain Society in 1995, JACHO, 1999)• Aggressive marketing of opioids for CNP citing these studies.• Use of opioids to treat CNMP increased & incorporated into
clinical guidelines becoming an accepted, but non-evidence-based standard of care.• Portenoy & Foley, 1986; Nyswander & Dole, 1986) • “The Tragedy of Needless Pain”, (Melzack, 1990)
• Many of the original medical proponents have been investigated for industry ties and conflicts of interest.
• Finally as overdoses and addiction explode – the clothes of the emperor are being critically considered.
14
Critical research gaps in treatment of chronic non-cancer pain using opioids
• Lack of effectiveness on long-term benefits in context of known harms of opioids (incl. drug abuse, addiction, & diversion)
• Insufficient evidence for optimal approaches to risk stratification, monitoring, or initiation & titration of opioid therapy
• No evidence on: • Utility of informed consent & opioid management plans• Utility of opioid rotation• Benefits & harms of methadone or high dose opioids• treatment of patients with chronic non-cancer pain at
higher risk for drug abuse or misuse.Chou R J Pain. 2009
Chronic Pain and the Unexpected• 66 yo ♂ here for follow-up Primary Care.• Hx: Longstanding T2DM, HTN, OSA and Severe diabetic
neuropathy confirmed by Neurology.• Ibuprofen & Acetaminophen tried with no or limited effect.• Pt still requesting treatment for lower extremity pain.• New meds prescribed:
• Oxycodone (5 mg) / APAP (325 mg). 1 tab po qid X 28 days; Disp: #112.
• Gabapentin 300 tid (tapered start).• FU visit in 1 month.• 12 days later patient calls:
• Out of pain medication & requesting oxycodone refill. • Took more pills than Rx’d b/o inadequate pain relief.• Pain is 12/10.• Not taking gabapentin because “Doesn’t do anything”.

Goals
•Goal 1: Avoid / Mitigate this situation. • Set expectations - Informed consent
• Assess for risk.
•Goal 2: Maximize Benefit (Safety & Quality of Care).
• Pain management plan.
•Goal 3: Minimize risk.
• Prepare for the unexpected.
• Establish monitoring plan.
16
Case
Setting expectations - Informed consent
Set Expectations: • “Pain free” is not a realist expectation. • Treatment as a “Trial” – Reserving the right to stop
the medications if response is inadequate or unsafe.
Patient Responsibilities:• Communication if unacceptable levels of post-operative
pain, Medication Disposal, No sharing.
Discuss Benefits & Risks Opioids (Focus: Safety)• Benefits
• Pain relief, Increased function, Quality of Life.
• Risks • Side effects: physical dependence; sedation.• Misuse, abuse, addiction, overdose, death.• Drug interactions.

"for instance because of the experience or feeling it caused"

Pain management planning• Non-opioid pain medications
• Adjunct Medications to Opioids.• Acetaminophen / NSAIDS (Naprosyn).• Tylenol with Codeine.• Adjunct analgesics: Gabapentin, Amitriptyline.• Local measures (heat / cold / massage, etc.).
• Non-medication based Therapies.• Physical Therapy / Counseling / Optimize transportation
& housing.
• Plan for unexpected outcomes• Develop & implement policies.• Discuss policy pre-operatively with patient when
consenting.• Instruct patient when, how, & who to contact.
• Establish specific strategies for:• Treatment escalation.• Dealing w/ aberrant medication taking behaviors.

Case
“Ran out meds early” is a symptom. 1.It happens - it’s a risks of using
opioid medications - first talk with the patient.
• Review treatment agreement & clinic policy.• Reset expectations.
2.Figure it out & make a Diagnosis.• Unfounded patient expectations? • Inadequate pain-management? • Progression of disease?• New disease process? • Misuse? Addiction? Diversion?

4 yrs later: Managing chronic pain• Pt (70 yo) stable on MS Contin 60 mg bid. (~3.5 ys.).
• Today: Monthly Follow-up visit for refills. • Patient reports:
• Pain manageable. (PEG = 5 → 5).• Feeling more anxious (PEG = 3 → 7).• Less active. (PEG = 4 → 9).• Increasingly forgetful. • Recently fell & hit head.
• Despite repeated attempts, unable to taper opioid - Pt states “its the only thing that works”.

Case
Aberrant medication-taking behaviors
o Requests for increase opioid dose.o Requests for specific opioid by name, “brand name
only”.o Non-adherence w/other recommended therapies
(e.g., PT).o Running out early (i.e., unsanctioned dose
escalation).o Resistance to change therapy despite AE (eg. over-
sedation).o Deterioration in function at home and work.o Non-adherence w/monitoring (e.g. pill counts,
UDT).o Multiple “lost” or “stolen” opioid prescriptions.o Illegal activities – forging scripts, selling opioid
prescription.

Urine Drug Testing (UDT): Key to opioid prescribingWhy to do it:
• Provides objective information supporting safety (patient & public).
• Demonstrates med adherence. Is patient using the Rx?• Shows substances that patient shouldn’t be using?• Helps prevent abuse if pts know drug tests will occur.
How to Discuss UD Testing with Patients:• Some providers feel awkward discussing UDT’ing.• Frame as a personal & public health safety issue.• Remind patients that:
• Opioid are dangerous & Providers can’t tell which pts will develop problems.
• Its the Standard of care for treatment with these medications.
• You monitor all your patients: Universal Precautions (No singling out).
When to Perform Urine Drug Testing:• No clear standard: Regular scheduled basis vs. Random.• Implement when concerns arise (e.g. aberrant behavior).

Urine Drug Testing is ComplicatedC
ase
When to refer•Possible addiction or misuse.
• Addiction Specialist.• Substance Abuse Treatment Program.
•Assistance with or discomfort with prescribing high levels of chronic opioids.• Pain Specialist.
•Assistance w/ tapering / discontinuing high doses of opioid.• Addiction Specialist.• Substance Abuse Treatment Program.
31
Case
When to discontinue: Risks > Benefits
DO NOT have to prove diversion/addiction to stop opioid therapy.
Absolute Indications for Stopping Opioid Therapy.• No benefit identified. • Harms from treatment. • Cannot keep medications safe. • Unable / unwilling to comply w/ required monitoring.• Active addiction (unstable).• Illegal activity / medication diversion. • Violent / abusive behaviors → practice staff/clinicians.
Relative Indications for stopping opioid therapy• Based on clinical judgment (in absence of an absolute
indication).• Risks of opioid treatment outweigh potential benefits.

Summary• Universal Precautions:
• Screen & assess risk for risk of substance misuse / abuse.
• Define the etiology of the pain.• Provide informed consent
• Discuss Risks/Benefits of Opioid Therapy
• Set expectations - establish realistic Goals of Care.• Consider & use all modes of pain management
• Opioids may not be of benefit and not be indicated.
• Start Low / Go Slow• Use an outcomes-oriented trial-based mindset.
• Never stop monitoring.• Functional Goals / Use the PEG.• Urine Drug Testing & Pill Counts (Scheduled & Random).
• Make a diagnosis when the unexpected occurs.• Discontinue opioids when Risks > Benefits.• Access resources a/o ask for help. 36
