Significant numbers of patients will improve Use Internet and written resources and other members of a multidisciplinary team to educate patients Menu Following this module, participants will be able to: Assess motivation in patients with fibromyalgia (FM) Use simple strategies to increase patients’ readiness to incorporate non-pharmacologic and lifestyle Give evidence-based, non-pharmacologic interventions as treatment for FM Recognize the role of an interdisciplinary team in FM management Objectives Case Study Patty is a 32-year-old patient in your practice who was diagnosed with FM that appeared to start after she slipped on some ice. Patty was advised to attend a local “new movement class” targeting de-conditioned patients to increase physical activity. She was also prescribed a medication that would target pain – her most disabling symptom. Video 1 Questions 1. What non-pharmacologic interventions have been shown to help with FM? 2. How might you help to motivate Patty? 3. How could your interdisciplinary team (your own team or resources in your community) assist in the management of patients with FM? Take the time to answer each of the questions Management of FM: Recommended Treatment Approach Multidisciplinary therapy individualized to patients’ symptoms and presentation is recommended A combination of non-pharmacologic and pharmacologic therapies may benefit most patients Non-pharmacologic Aerobic exercise Cognitive behavioral therapy (CBT) Patient education Strength training Acupuncture* Biofeedback* Balneotherapy* *Limited evidence for efficacy exists Balneotherapy: treatment of disease or health conditions by bathing Goldenberg et al.

Video 2 Video de-brief Summary Non-pharmacologic therapies are an important first-line treatment for patients with FM Compliance to lifestyle interventions can be increased by assessing and intervening with motivational interviewing techniques The use of multidisciplinary resources can improve outcomes and facilitate time-efficient treatment Menu Following this module, participants will be able to: Link the medications useful in treatment of fibromyalgia (FM) Match medication properties and side effects with therapeutic targets for patients with FM Articulate safety issues with medications commonly used to treat FM Objectives Case Study Patty is a 32-year-old patient in your practice who was diagnosed with FM that appeared to start after she slipped on some ice. She presented with a typical symptom complex: generalized pain, fatigue, non-restorative broken sleep and mental fogging. You asked her after the first visit to review medication options with a pharmacist who works as part of your interdisciplinary team. Exercise Complete the worksheet with your partner For each class of medication, indicate what is the effect of each symptom, using -, +, ++ or +++, and describe the most common side effects.

Medical Management of FM: Considerations (cont’d) Use opioids with caution; keep doses low Refer to the new Canadian practice guideline on use of chronic opioid therapy for non-cancer pain Always augment with non-medical therapy Polypharmacy may be necessary, but keep doses low and be mindful of side effects and function Polypharmacy Often necessary for symptom control May exacerbate or cause some of the target symptoms of FM (cognitive impairment, sleep disturbance, fatigue) Be aware of drug interactions (e.g., serotonin syndrome) Best Evidence: Medication Options in FM (alphabetical order) Medication Mechanism of Action Amitriptyline (desipramine, doxepin, nortriptyline) TCA (NE > 5HT) Duloxetine SNRI Gabapentin Efficacy in Overall FM Management Effect on Major Symptoms Off/OnLabel Indication Pain, sleep, anxiety (poor long term) Off +++ Pain, depression, anxiety On 2 binding: ↓neuronal excitation ++ Pain, sleep, anxiety Off Pregabalin 2 binding: ↓neuronal excitation +++ Pain, sleep, anxiety On Tramadol Opioid agonist SNRI ++ Pain Off + +++: strong evidence for use/efficacy; ++: moderate evidence use/efficacy; +: some evidence use/efficacy; -: no evidence for use/efficacy GABA, γ-aminobutyric acid; NE, norepinephrine; SNRI, serotonin-norepinephrine reuptake inhibitor; TCA, tricyclic antidepressant Some Evidence: Medication Options in FM (alphabetical order) Effect on Major Symptoms Off/onLabel Indication Comments ± Sleep Off Open label study CB 1 receptor agonist + Sleep Off Lack of effectiveness in FM pain Cyclobenzaprine Muscle relaxant (NE) + Pain, sleep (poor long term) Off Pramipexole Dopamine agonist + Pain, fatigue Off Limited population studied Sertraline SSRI ± Pain, depression Off Compared versus physical therapy Venlafaxine SNRI > SSRI + Pain, depression, anxiety Off Limited FM study Medication Mechanism of Action Atypical antipsychotics Dopamine Cannabinoids Efficacy in Overall FM Management +++: strong evidence for use/efficacy; ++: moderate evidence use/efficacy; +: some evidence use/efficacy; -: no evidence for use/efficacy SSRI, selective serotonin reuptake inhibitor No Evidence: Medication Options in FM (alphabetical order) Medication Mechanism of Action Rationale for Use Concern for Use Benzodiazepines GABA increase Anxiety Addiction Side effects NSAIDs Prostaglandin inhibition Analgesia NSAID-related side effects Opioids Opioid receptor agonists Analgesia Addiction Side effects Stimulants (dextroamphetamine, methylphenidate) NE Dopamine Fatigue Diversion Abuse Zopiclone GABA Sleep +++: strong evidence for use/efficacy; ++: moderate evidence use/efficacy; +: some evidence use/efficacy; NSAID, non-steroidal anti-inflammatory drug -: no evidence for use/efficacy Video 2 Video de-brief Summary Establish realistic treatment goals Important to manage patient expectations Chose medications that target the most troublesome symptoms Start low, go slow – reassure Use polypharmacy with care Opioids are controversial Menu Following this module, participants will be able to: Differentiate the concepts of functional remission versus full symptom remission Establish realistic therapeutic goals with patients Use interdisciplinary team resources to manage patients with fibromyalgia (FM) Objectives Case Study Patty is a 32-year-old patient in your practice who was diagnosed with FM that appeared to start after she slipped on some ice. After communicating the diagnosis to her, you referred her to a local FM lifestyle program. She was also started on a medication targeting sleep restoration, her most debilitating symptom at presentation. She presents for a follow-up visit. Video 1 Questions 1. How do you monitor the effectiveness of treatments? 2. What is the realistic endpoint of therapy for FM? Is full remission of symptoms a reasonable goal? 3. How do you explain or negotiate therapeutic goals to patients? 4. How could you use an interdisciplinary team (your own team or resources in your community) to manage your patients with FM? Take the time to answer each of the questions Monitoring Treatment Currently, there is no currently validated acceptable tool for assessing response to treatment Consider evaluation of patients with FM in these dimensions: Pain Fatigue Sleep Functionality (physical and psychological) Mood Functional versus Symptom Remission Symptomatic remission is resolution of all symptoms associated with the condition Functional remission is improvement of symptoms to the point where patients can maximize function (vocational, interpersonal, social) Although most patients with FM will not attain full symptom remission in the short term, the natural history of FM is more positive Fate of Patients with FM Reassure patients that FM is not progressive and that symptoms remain stable over time1 50% were moderately to greatly improved (3 year follow-up)2 • The baseline predictors for a favorable outcome: younger age and less sleep disturbance2 Successful management requires an upbeat, optimistic approach and EARLY initiation of effective, individualized therapy 1.
