1 Easing the Pain Approaches to Managing Pain Associated with Serious Illness Christine S.Ritchie, MD, MSPH, FACP, FAAHPM Harris Fishbon Distinguished Professor Courtesy J Kutner 2 Definitions Acute pain: An unpleasant sensation and emotional response to that sensation Cut, bruise, bone fracture, tooth ache Chronic pain: Unpleasant sensation that continues for prolonged period of time beyond expected time of healing Pain on most days for more than 3 (or 6) months May or may not be associated with identified disease process 3 Pain---how common is it? Community-dwelling adults: 30-50% Nursing homes: 60-80% Among palliative care patients: 83% 25% have severe or overwhelming pain Pidgeon T, et al. BMJ Supportive & Palliative Care

2 Pain-- A complex experience Bio Disease-related mechanisms Biologic mechanisms of psychiatric illness Pain A complex experience Psycho Distress Anger Fear Traumatic life events Social Environmental stressors Close personal relationships 7Gatchel, Am Psychol, 2004; Gatchel, Psychol Bull, Sibille et al.

3 Pain-- Multimodal management Cognitions Emotions Behaviors Attention Psycho Bio Social Medication Exercise Surgery Sleep Healthcare Family Work Therapeutic Strategies for Pain Pharmacotherapy Nonpharmacologic: Rehabilitative approaches Behavioral approaches Complementary and alternative approaches Lifestyle changes 9 Pharmacotherapy: WHO 3-step Ladder 1 mild ASA Acetaminophen ± Adjuvants 2 moderate A/Codeine A/Hydrocodone A/Oxycodone A/Dihydrocodeine Tramadol ± Adjuvants 3 severe Morphine Hydromorphone Methadone Fentanyl Oxycodone ±Adjuvants Acetaminophen Safest pain medication on market Max allowable dose (4 grams over 24 hours) Most individuals take considerably less Safe for those over 70 to set limit at 3gm/day Need to read labels regarding presence of acetaminophen in other products Too much acetaminophen can cause liver damage Recommended first-line therapy 3

4 Non-Steroidals- NSAIDS (e.g. ibuprofen, naproxen) Most popular analgesic agents on market Significant safety issues > 100, 000 hospitalizations each year > 16,000 deaths each year Can precipitate heart failure episodes, worsen blood pressure, worsen kidney function Can increase risk of stroke/heart attack Frequent monitoring required Opioids (e.g. morphine, oxycodone, hydrocodone, fentanyl patch) Many side effects (constipation, lethargy, nausea, itching) Effective at treating pain Likely underused by older adults Many barriers to use Patient Physician Treatment Considerations Benefits Associated With NSAID/Opioid Use (Effect Sizes) History and Physical and Appropriate Evaluation Analgesia Improved function Improved quality of life Adverse effects Comprehensive Benefit to Harm Evaluation Overdose Abuse/Misuse patient or contact Addiction Drug-drug and drug-disease Interactions Physical dependence and tolerance Opioids 3 Oral 1 Topical 2 Pain reduction Physical 0.22? 0.43 functioning Sleep?? 0.87 improvement Quality of life???

6 Constipation: Management Softeners Docusate Cathartics Senna Biscadoyl (Dulcolox) Osmotic Laxatives Magnesium/aluminum salts Lactulose Sorbitol Enemas Fiber- usually not indicated in frail or end-of-life patients Sedation and Cognitive Impairment Discontinue non-essential medications. Evaluate and treat other potential causes. If analgesia satisfactory, decrease dose by 25%. If analgesia inadequate or symptoms persist despite dose reduction: trial of psychostimulant (if sedation) or neuroleptic (if delirium). switch to an alternative opioid. trial of other invasive/non-invasive approach to decrease systemic opioid requirements. When dose-limiting side effects occur with opioid pharmacotherapy... More aggressive treatment of adverse effect(s) Opioid-sparing strategies Analgesic adjuvants Alternate route (e.g. intraspinal) Anaesthetic/Neurolytic procedures PM&R approaches Cognitive therapy Complementary therapies e.g., acupuncture, massage, music therapy Opioid rotation Opioid Prescribing Over Past 16 Years Olfson et al.

8 Nonpharmacologic Approaches Behavioral Therapies Cognitive-Behavioral Therapy Replacing maladaptive cognitions, emotions, behaviors with more adaptive ones Increasing functional capacity through improved coping Other Behavioral Therapies Relaxation training Mindfulness based stress reduction Nonpharmacologic Therapies Cognitive Behavioral Therapy (CBT) Areas addressed by CBT: catastrophizing acceptance of the pain condition avoidance of activity due to unrealistic concerns about harm Your emotions Your thoughts CBT Your behaviors 30 Relaxation Training Mindfulness-based Stress Reduction 31 Deep breathing Guided imagery Progressive muscle relaxation Many tools online: on-guide h/stress/relaxation.htm Awareness and thinking as different capacities. awareness balances out inflammations of thought, emotional agitations and distortions Paying attention to one s pain 32 John Kabot Zin The Mindfulness Solution to Pain; 8

9 Mindfulness-based Stress Reduction Complementary and Alternative Approaches Body Scan- bringing awareness to each body part. Acupuncture Herbs: Feverfew Breathing- calming your mind and grounding your breath. Butterbur. Cayenne (capsaicin) Chamomile tea. Dandelion Ginger Distractions- games, conversations, reading a book 33 John Kabot Zin The Mindfulness Solution to Pain; 34 Gingko Stinging Nettle Willow Bark. Supportive Pain Management = Team Care Symptom management Follow-up Nutrition Support Supportive Care and Counseling Intake Review Tailored Plan of Care Spiritual Care Financial and Social Support Coordination Tailored Interdisciplinary Assessment &Treatment Plan Whole Person Approach 9

10 Summary Pain is common in the setting of serious illness Pain is a complex experience influenced by biology, environment and one s emotions and cognitions Many effective medicines for pain also have significant side effects A holistic approach includes pharmacologic and nonpharmacologic approaches to pain with input and support from an interdisciplinary team
