Doc, I’ve Got This Pain Steven M. Moskowitz, MD Senior Medical Director, Paradigm Key Take-Home Lessons on Chronic Pain By the end of this presentation, you should understand the importance of systematic management by physicians Objective assessment and criteria Careful Selection Avoid trial and error Measure effectiveness Withdraw treatments that are not effective Perspective and context 2 Chronic Pain Remains a Chronic Problem Despite innovation, chronic pain persists as one of the most chronic problems in the US. $100 billion estimated annual cost in the US of health care, lost income and lost productivity due to chronic pain according to the NIH1 76 million Americans suffer from chronic pain according to the NIH1 26% of Americans age 20 years and older—an estimated 76.5 million Americans—suffer from “chronic pain” 80% of physician office visits due to pain4 Pain medications are the 2nd most commonly prescribed drugs in the US5 Generic Vicodin is top medication prescribed Sources: 1.

According to Laxmaiah Manchikanti, CEO for the American Society of Interventional Pain Physicians. 4 Back Pain A Common Symptom Back Pain, All Pain, Is Often A Lifestyle Condition ■ 70-80% lifetime incidence. Up to 10% incidence per year ■ The CDC 2010 reported that 30% of people had LBP in the prior 3 months1. • Ages 18-24 (21%), 25-44 (27%), 45-54 (32%), 55-64 (33%), 65-74 (30%), >75 (34%) • Neck pain: less frequent by about 40-50% • Joint pain: Age 18-44 (21%), 45-64 (42%) • Hospice care patients symptoms at last hospice visit before death: Pain 33.3% ■ 250,000 lumbar surgeries are performed annually • 2006-2007 rates have kept steady since 1996-97 for 45-64 year old group, increased by 67% for those over 65 • For comparison, knee replacement has increased by over 100% and total hip replacement by just under 100% 1. CDC Health, United States 2020 5 Back Pain Back surgery is not a wise “last resort” ■ Having back surgery is a major risk factor for having more back surgery – 18.9% cumulative risk of additional back surgery in 9 years • Reoperations after lumbar disc surgery: a population-based study of regional and interspecialty variations1 – Patients with one reoperation after lumbar discectomy had a 25.1% cumulative risk of further spinal surgery in a 10-year follow-up • Risk of multiple reoperations after lumbar discectomy: a population-based study2 ■ Most benefits of surgery, for those who benefit from surgery, last 1-2 years compared to those not having surgery 1. 2.

The pain experience is both individual and complicated Pain Perception Nociception Somatosensory System Pain Neurological Interpretation Neuromodulation Cognitive Interpretation Emotional Influence and Response The Pain Experience Components of Clinical Pain Nociceptive Pain Pain sensation from damage, inflammation Neuropathic Pain Pain from nerve compression, damage Central Mechanisms Secondary impairments Complex central nervous system interpretation, regulation, sensitization Myofascial pain, stiffness, deconditioning, debilitation Psychosocial Component Factors that impact illness perception, adaptive coping, compliance 13 Chronic Pain is Not Acute Pain Acute pain typically resolves within a certain time frame. Pain lasting beyond this time is what we refer to as chronic pain. Treatment should differ from acute. Acute Pain Chronic Pain The clinical and claims approaches differ 14 Is All Chronic Pain The Same? Knowing the terminology can help. ■ Acute pain ■ Acute pain with psychological dysfunction ■ Chronic pain ■ Chronic Pain with psychological dysfunction ■ Chronic pain syndrome 15 Chronic Pain Chronic pain is a syndrome that emerges at variable speed. atrophy depression atrophy insomnia insomnia PAIN PAIN PAIN weight gain fear of movement medical issues addiction life roles Acute Pain (0-3 months) Transitional (3-6 months) Chronic Pain Syndrome (Greater than 6 months) 16 Psychological Factors .

How are the medications working? The Oxycontin is great, but I need more. How was that epidural steroid injection? I felt great for two days! We’d better get you an MRI and schedule an ESI and some facet injections. Doc, can I have a refill of my Oxycontin? I need a higher dose. And can I get validated parking for my truck? 25 Biopsychosocial Approach to Procedures Be systematic Clarify the Diagnosis Coordinated and Appropriate Treatment Clinical assessment Treatment criteria – Objective criteria for diagnosis Criteria for diagnostic testing – Clear reasons for this test Careful interpretation (Danger) – Common occurrence of incidental findings Behavioral factors – Catastrophizing, fear avoidance, self efficacy, secondary gain – Carefully selected Treatment effectiveness measures – Subjective and objective Clear intervention criteria – Increase or discontinue Behavioral interventions – Set realistic expectations, accountability, perspective 26 Case 2: New patient, Mr. Spinatus; Accepted shoulder claim Doc, I can’t lift my shoulder! ■ MD: I read your record and see that you are 43 years old, you are a carpenter and your shoulder has been hurting for 3 years. Is that correct ■ Patient: Yes it is horrible. When I was in Cabo last week, it hurt the whole time. I could hardly use it. ■ MD: I noticed you have quite a tan. Where is the pain exactly? The Case of the Disabled Beachcomber… ■ It starts at my shoulder and goes down my arm to here (he points to his wrist). ■ I see you are on the Fenatyl patch, does it help? ■ Patient: It takes the edge off. The OxyContin helps more. ■ MD: Are you working? If not, I bet you want to get back to work. ■ Patient: I am on Disability (Social Secruity). ■ MD does examination: calls out: normal muscle tone, decreased ROM, no sensory loss. I see your old MRI showed bulging discs. ■ MD: I think you may have a pinched nerve. Lets get a new MRI of your neck and an EMG. I recommend we get a UDS. I would like to schedule an epidural steroid. Here is some information on SCS to look at also. ■ Patient: Doc, UDS? What are you saying? 27 New Patient: Accepted Shoulder Claim You are 43 years old, a carpenter, and your shoulder has been hurting for 3 years. Is that correct? It’s horrible!

(World Health Organization, International Classification of Function) ■ Studies repeatedly show that when you uncouple pain and function, function can dramatically improve ■ Objective measures ■ Measurement that is not subjective, not dependent on effort ■ Blood pressure, temperature, pulse, range of motion, calf measurement, reflexes, strength, gait ■ Functional measures examples (ODG 2012) – Work Functions and/or Activities of Daily Living, Self Report of Disability (e.g., walking, driving, keyboard or lifting tolerance, Oswestry, pain scales, return-to-work, etc.) – Physical Impairments (e.g., joint ROM, muscle flexibility, strength, or endurance deficits) – Approach to Self-Care and Education (e.g., reduced reliance on other treatments, modalities, or medications, such as reduced use of painkillers) 35 The Business of Chronic Pain Buyer beware ■ Rush to market promoted by for-profit drug and technology companies ■ FDA approval does not = effective or safe ■ To get FDA approval, you only need to submit 2 studies showing it is better than placebo, no matter how many studies show it is not (1) ■ Rampant off label use; lack of careful selection ■ Shift in physician training opportunities to procedural opportunities-glut of providers ■ Physical Medicine and Rehabilitation experience ■ Direct marketing to patients ■ Lack of regulation seen in other areas of medicine ■ Compare to acute care, core measures (Diabetes management, CHF management) ■ Lack of outcome measures or expectations (acute care cardiac success rates, CEA, complication rates) 1.
