3 5 Key Facts: All pain is real. Emotions drive the experience of chronic pain. Opioids often make pain worse. Treat to improve function. Expectations influence outcomes.

4 Pain Definition An unpleasant sensory and emotional experience associated with actual or potential tissue damage. The International Association for the Study of Pain (Mesky,1979)

6 How does acute pain become chronic pain? Sensitization Structural Remodeling Surgery or injury causes inflammation Peripheral Nociceptive Fibers Sustained currents Peripheral Nociceptive Fibers CNS Neuroplasticity Hyperactivity Transient Activation Sustained Activation ACUTE PAIN CHRONIC PAIN Woolf CJ, et al.

9 NORMAL PAIN RESPONSE

10 CENTRAL SENSITIZATION

11 Chronic Pain Syndrome Pain > 6 months. Depression, anxiety, anger, fear. Restriction in daily activities. Excessive use of medications and medical services. Multiple, non-productive tests, treatment, surgeries. No clear relationship to organic disorder.

12 Pain Assessment Scale: Clinical definition of pain: Whatever the patient says it is... unless proven otherwise

13 Reasonable Goals of Pain Management: Enhance Quality of Life!! Maintain function. Improve function. Reduce discomfort by 50%.

14 Pharmacologic Non-Opioid NSAIDs. Tricyclics and SNRIs. Anti-convulsants. Muscle Relaxants (AVOID SOMA/ carisoprodol). Topicals.

15 Simple Approach to Treating Non-Malignant Pain If it hurts.. If it hurts a lot If it REALLY hurts Give ibuprofen Give hydrocodone Give something stronger If it still REALLY hurts Give more Hmmm. Something is just not right. If it REALLY hurts for a long Keep giving more time. If it s getting worse no matter what I prescribe Discharge patient

16 Treating Chronic Pain with Opioids Clinical Trial. Ongoing Assessment. Need exit strategy.

17 Appropriate Opioid Prescribing Utilizing CDC Guidelines Never vs. Always vs. It depends? Should be part of a larger, comprehensive management program based on assessment, trust, relationship, and verification. Conscientious, judicious use. Balance risks and benefits. Informed consent and agreement. Communicate and connect. Assess and Document 5 A s -- Analgesia, ADL s, Adverse Side Effects, Aberrancy, Addiction. 17

18 CDC: #5 Use lowest effective dosage When opioids are started, clinicians should prescribe the lowest effective dosage. Clinicians should use caution when prescribing opioids at any dosage, should carefully reassess evidence of individual benefits and risks when considering increasing dosage to 50 morphine milligram equivalents (MME)/day, and should avoid increasing dosage to 90 MME/day or carefully justify a decision to titrate dosage to 90 MME/day. 18

19 High Opioid Dose and Overdose Risk * Overdose defined as death, hospitalization, unconsciousness, or respiratory failure. Dunn et al. Opioid prescriptions for chronic pain and overdose. Ann Int Med 2010;152:85-92.

20 CDC: #6 3-7 Day Guideline Long-term opioid use often begins with treatment of acute pain. Clinicians should prescribe the lowest effective dose of immediate-release opioids and should prescribe no greater quantity than needed for the expected duration of pain severe enough to require opioids. Three days or less will often be sufficient; more than seven days will rarely be needed. 20

21 Eyes open to the risks: Slippery Slope The longer you use opioids, the greater the risks and the risks seem to rise fast. Shah A, Hayes CJ, Martin BC. Characteristics of Initial Prescription Episodes and Likelihood of Long-Term Opioid Use United States, MMWR Morb Mortal Wkly Rep 2017;66: DOI: mmwr.mm6610a1 21

22 One- and 3-year probabilities of continued opioid use among opioid-naïve patients, by number of days supply* of the first opioid prescription United States,

23 CDC: #11 Avoid Benzodiazepine- Opioid Combination Clinicians should avoid prescribing opioid pain medication and benzodiazepines concurrently whenever possible. 23

24 CDC: EVIDENCE ABOUT OPIOID THERAPY Benefits of long-term opioid therapy for chronic pain not well supported by evidence. Short-term benefits small to moderate for pain; inconsistent for function. Insufficient evidence for long-term benefits in low back pain, headache, and fibromyalgia. 24

25

26 Problems with Opioids Side Effects. Tolerance and physical dependence. Loss of function. Perceive emotional pain as physical pain (chemical copers). Hyperalgesia.

54 This is a false dichotomy Aberrant drug use behaviors are common in pain patients 63% admitted to using opioids for purposes other than pain 1 Pain Patients VS Drug Abusers 35% met DSM V criteria for addiction 2 92% of opioid OD decedents were prescribed opioids for chronic pain. 1.
