• Chronic pain is a serious public health issue1, 2
• Patients with chronic pain, clinicians, payers, employers, and the government, are confronted by two dual interrelated issues1:
• Poor understanding and often inappropriate treatment of pain, including prescription therapy
• Misuse, abuse, and diversion of medications intended to treat pain, namely opioids
• These challenges must be addressed in parallel to ensure that concerns about abuse and misuse of opioids do not preclude clinically appropriate opioid therapy for patients who need it3,4
• There needs to be R&D investment in new non-opioid chronic pain treatments and models of care, which could potentially help to address these challenges5

Chronic Pain Is a Serious Public Health Burden
$560–635billion
• Exceeds costs of cardiovascular disease ($444B), diabetes ($174B), and cancer ($125B)
• High health care costs globally, although estimates vary
~100million
• 23 million report ‘being in substantial’
pain
• Exceeds prevalence of cardiovascular disease (~27M), diabetes (~26M), and cancer (~12M) in US population
• Similar prevalence estimates globally1. IOM. Relieving Pain in America: A Blueprint for Transforming Prevention, Care, Education, and Research. Washington, DC: The National Academies Press; 20112.

CNS and Peripheral Pain Signaling Pathways
Descending tracts
play a role in pain modulation via the midbrain periaqueductal gray
matter and nucleus raphe
Ascending tracts
(e.g., spinothalamic) convey pain signals to the brain, where they are
processed by the thalamus

Chronic Pain Is a Biological, Psychological,and Social Phenomenon1
• For many patients with chronic pain, effective assessment and treatmentis multimodal and multidisciplinary, taking into account:• Biological factors (mix of symptoms,
type of pain, etc.)• Psychological, emotional and cognitive
factors (anxiety, depression, anger, fear of movement, catastrophizing)
• Social factors (social and financial circumstances)

Multimodal Chronic Pain Management1
• For many patients with chronic pain, effective assessment and treatmentis multimodal and multidisciplinary
• Nonpharmacologic intervention that can be chosen based on the patient’s profile and treatment availability• Psychological therapies, such as cognitive-behavioral therapy, relaxation, biofeedback• Rehabilitative/physical therapies, such as stretching, exercise, massage• Other complementary alternative medicine, such as yoga, acupuncture• Patient self-management, such as pacing of activity, brief planned rests
• Pharmacological interventions
• Interventional Techniques (i.e., for chronic spinal pain)• Spinal interventional techniques (Diagnostic & therapeutic interventional techniques)• Cervical, thoracic, and lumbar interventional techniques (i.e., facet joint, epidurals,
decompression, neurotomy)• Implantables (i.e., Spinal Cord Stimulators, Implantable Intrathecal Drug Administration)

Comprehensive Pain Assessment Involves the Evaluation of Three Elements
Identify and document potential underlying
cause of pain1
• Evaluate health status, medical history, comorbid illnesses, prior and current medications, family history, etc
• Assess duration, location, and the likely source of pain
• Use advanced diagnostic techniques for certain patients
Record pain severity,
impact on function,
mood, and sleep1
• Assess and record pain severity, eg, using VAS
• Evaluate impact on function, sleep, mood
At present, rarely done in primary care setting, and rarely (if ever) included in available EMR modules
Identify and documenttype(s) of pain
pathophysiology1-5
• Evaluate pain descriptors, presence of allodynia, hyperalgesia1
• Use tools to help determine the type of pain pathophysiology:
ID Pain® screening tool (6-item scale to identify non-nociceptive pain)2
PainDETECT (detects neuropathic pain in low back pain patients)3
Wolfe FM Questionnaire4
or FM Survey Questionnaire5

ID Pain® screening tool (6-item scale to identify non-nociceptive pain)
• Score of ≥ 3 was shown to indicate the presence of a neuropathic component of pain
• ID-Pain consists of 5 sensory descriptor items and 1 item relating to whether pain is located in the joints (used to identify nociceptive pain)
• Developed in 586 patients with chronic pain of nociceptive, mixed or neuropathic etiology, and validated in 308 patients with similar classifications as determined by pain specialist diagnoses
• In the validation study, 22% of the nociceptive group, 39% of the mixed group, and 58% of the neuropathic group scored above the cutpoint score of 3

When prescribing an opioid, employ risk mitigation strategies, such as: assess patient risk, use abuse-deterrent opioids, prescribe lowest effective dose, and monitor for abuse, misuse

Why Are Opioids Overprescribed?
• Opioids may be perceived as an easy choice since they can provide relief for various types of pain
• The prescriber may not consider etiologies/pathophysiology of pain or differential diagnosis
• Payers may provide greater access to generic opioids vs branded non-opioid medicines for pain or branded abuse-deterrent opioids
• Clinicians often underestimate patient risk for prescription opioid abuse1
• Even when a patient is identified as being high risk, there is limited use of opioid risk reduction strategies2
Assessing risk for misuse and abuse, and detecting such behaviors in
patients already receiving opioids is difficult.3 Therefore, risk reduction
strategies should be applied universally with every patient.

Adopting These Principles May Help Clinicians Achieve Better Outcomes in Chronic Pain• There are significant public health problems that must be addressed in
parallel• Poor understanding and often inappropriate treatment of pain• Misuse, abuse, and diversion of opioid medications• Development of new non-opioid chronic pain treatments and new models of care
• Clinical considerations• Consider psychological and social risk factors• Establish the pathophysiologic pain type(s) using available screening tools • Document pain assessments to enable effective management and monitoring • Use the pathophysiologic pain type(s) to help guide 1st line treatment selection• Consider opioid medications second line, unless contraindicated• Employ universal precautions to opioid prescribing• Set treatment goals with follow-up reevaluation of pain type and severity, impact,
medication management and referrals to specialists, when appropriate
