The ideal treatment of CNCP*
Why develop Guidelines?
• Recent guidelines ±10 years old• Advances in understanding FM
– Neurophysiologic– Treatments
• New diagnostic criteria (ACR 2010)*• Call for guidance & direction
– Requested by Canadian Pain Society*Wolfe at al. 2010. Arthritis Care and Research 62(5):600
The care gap…
• Prevalence of FM……2%• Delay in diagnosis…..5 yrs
• ↓ ↓ health care use after diagnosishealth care use after diagnosis• Improved health after diagnosisImproved health after diagnosis
m fitzcharles
Guidelines address three broad concepts in 46 recommendations
• Diagnosis and evaluation 12• Management 23• Patient trajectory and follow-up 11
new clinical concepts regarding FM have been incorporated into these guidelines.
The guide…diagnosis
DO NOT USE CRITERIA TO DIAGNOSE AN INDIVIDUAL PATIENTDO NOT USE CRITERIA TO DIAGNOSE AN INDIVIDUAL PATIENT
• FM is a clinical construct• Pain is the pivot + sleep problems, fatigue, cognitive changes etc
– 2/3 pain, 1/3 other• Patient must be examined
– To exclude other physical abnormality– Tender points not needed
• Simple blood testing only

Development of Chronic Widespread Pain over a 12 year period

Conclusions
Subjects move to and from chronic widespread pain (CWP) over time.
Predictive factors differ between subjects with no chronic pain (NCP) at baseline that develop CWP, and subjects that improves from CWP to NCP over a twelve year period.
The results suggest different pathogenesis in the two ends of the pain spectrum.Background
Chronic widespread pain (CWP) is often regarded as one end in a spectrum of more or less extensive pain distribution in the body. We have previously reported that subjects move to and from CWP over a three year period.
The aim of the study was to describe the multifactorial process of pain development over a 12 year period.Method
A baseline postal survey to 2425 subjects from the general population aged 20-74. Localisation of pain was reported by a drawing of the body. Subjects were classified as having no chronic pain (NCP; n=1466), chronic regional pain (CRP; n=588), or CWP (n=303). 68 subjects could not be classified. Pain development was followed over 12 years. The predictive values of baseline background factors (age, sex, education, smoking, alcohol consumption, immigrant, sleep structure) were analysed by multivariate logistic regression.
Results
1582 subjects (65%) responded at the 12 year follow up. Out of 959 subjects that had reported NCP at baseline, 66 (7%) reported CWP at follow up. Out of 192 subjects that had reported CWP at baseline, 35 (18%) reported NCP at follow up.
The development of CWP from NCP over 12 years was predicted by: -being aged 34-46 OR 2.5; 95% CI 1.2-5.4- low educational level OR 3.0; 95% CI 1.6-5.6- being an immigrant OR 2.4; 95% CI 1.1-5.1 - problems falling asleep OR 8.2; 95% CI 3.0-22.1
The improvement to NCP from CWP over 12 years was predicted by:- never being a smoker OR 3.8; 95% CI 1.4-10.0 - drinking alcohol weekly OR 3.5; 95% CI 1.1-11.4 - no nightly awakenings OR 4.5; 95% CI 1.1-17.9 NCP CRP CWP

swelling etcl
The guide…diagnosis cont.
• As early as possible (level 5)• Primary care is ideal setting (level 1) : early Primary care is ideal setting (level 1) : early
diagnosis reduces disease-related anxiety (major diagnosis reduces disease-related anxiety (major driver of healthcare utilization: THERE MUST BE driver of healthcare utilization: THERE MUST BE SOMETHING TERRIBLY WRONG WITH ME!)SOMETHING TERRIBLY WRONG WITH ME!)– Specialist referral only if (level 5)
• Atypical symptoms• Difficulties in management• eg. sleep specialist, psychologist

Treatment objectives
Think…………….Think…………….
• symptom based treatments
• mechanisms based treatments

• Aim to – symptoms– Maintain / improve function
The guide…management key points
• Self-management strategies are imperative (level 1)
• Internal locus of control– Patient active participant!! (level 1)– Multimodal approach (level 1)– Realistic goals, coping strategies (level 5)– Pacing, but continue normal life (level 4)
The guide….non pharma treatments
• Exercise (level 1)– Best available evidence – Any type
• aerobics, water based, stretching, etc.
• CAM – Insufficient evidence (level 1)– Encourage disclosure of use (level 5)
WHAT IS SELF MANAGEMENT?
“ The individual’s ability to manage the symptoms, treatment, physical and social
consequences and lifestyle changes inherent in living with a chronic condition”
Barlow 2002
Chronic Pain Self-Management*
* SLIDE CONTENT COURTESY OF DR SANDRA LEFORT, MEMORIAL UNIVERSITY
• Based on the Stanford Chronic Disease Self-Management Program (K Lorig)
• Active is better than passive• Keep Wellness in the foreground (no more PAIN
DIARIES!) • The patient is the “expert” who works in
partnership with their HCP• The patient takes responsibility for their own
health, uses their mind for pain management, uses pacing, problem-solving, action plans and goal-setting
http://patienteducation.stanford.edu/programs/cpsmp.html
• Develop nonjudgmental awareness of moment-to-moment experience within a context of openness, kindness, tolerance and acceptance of perceptible sensory, mental and emotional phenomena.
• Can improve coping and health-related quality of life in many chronic conditions including chronic pain.

The guide…. pharma treatments
• No perfect drug• Lowest dose, gradual increase (level 5)• Expect only a modest response• Consider combination drugs (level 5)• Be knowledgeable regarding drug mechanisms
(level 5)• Constant evaluation re risk vs. benefit (level 5)
Cautions re pharmacologic treatments
• Change 1 thing at a time
• Side effects often similar to symptoms of FM
• Caution re dependency on pills which fosters “passivity”
Symptom based management• Pain
– Analgesics (simple, mild NSAIDs, weak opioids)– Anticonvulsants (gabapentinoids)– Antidepressant group– Opioids– ??? Dopamine agonists
• Sleep– Gabapentinoids– TCA’s– Benzodiazepines– Cannabinoids,– Atypical agents…quietapine, trazadone, sodium oxybate
• Mood – Your best choice taking pt individual characteristics
• Fatigue– Bupropion, methylphenidate, modafinil
The art of FM pharmacotherapy
• Patient tailored treatment• Pain, fatigue & mood+++….SNRI• Pain & sleep++++…..anticonvulsant• TCA’s still have a place
• LOW, LOW doses of drugs
The guide…. pharma treatments cont.
• WHO step-up analgesic ladder (level 5)• NSAIDS – low dose, short use (level 5)• Tramadol – moderate/severe pain (level 2)• Strong opioids – discouraged (level 5)• Cannabinoid (pharma) – sleep (level 3)
Patients choice of medications
• Internet survey ..2500 FM patients USA• Most common medications
– Acetaminophen, ibuprofen, naproxen, cyclobenzaprine, amitriptyline, ASA
• Perceived as best– hydrocodone, aprazolam, oxycodone, zolpidem,
cyclobenzaprine, and clonazepam.
Pharmacologic treatments ….mechanism based
• Anticonvulsants– Gabapentinoids sensitization
• Antidepressants– norepinephrine– serotonin– dopamine
• ? Dopamine central

serotonin norepinephrine opioids cannabinoids
The guide…. pharma treatments cont.
• Anticonvulsants– Explain mechanism to patient (level 5)– Low dose (level 1)
• Antidepressants– Explain mechanism to patient (level 5)– TCAs, SSRIs & SNRIs can be used (level 1)– Choice – MD knowledge, Pt characteristics (level 5)
How low can you go?
• Amitriptyline: 10mg at bedtime• Duloxetine: 30mg in am with food*• Pregabalin: 25-50mg with supper*• Gabapentin: 100mg with supper
Consider polypharmacy (but no evidence)*I start even lower

Sleep and Fatigue
• Sleep: many have restless legspramiprexole (small studies: pathological gambling)
• Fatigue: exercise, activity, pacing
• ??? Stimulants
The guide…patient trajectory
• Follow-up time interval depends on MD judgment (level 5)
• New symptoms– Evaluate using clinical judgment (level 5)
• FM symptoms persist, wax and wane (level 3)• No value to dwell on past lifetime events, move
forward (level 5)• Empathetic and supportive relationship with PCP
is extremely important!
The guide…patient trajectory cont.
• Poor outcome when (level 5)– Passive patient– External locus of control– Untreated prominent mood disorder
• Outcome tools– Patient Global Impression of Change (level 3)– Goal attainment (level 5)– Do not use tender points for outcome (level 3)
The guide…work and cost
• Retention in workforce encouraged (level 3)• Rehab program if necessary (level 5)• Reduce costs by treating depression (level 3)
When do things go wrong?• MD
– Wrong diagnosis– Not attending to mood, sleep– Over treating….pills, investigations
• Patient– No goals, wants magic pill, unrealistic expectations– The passive, negative patient– Secondary gain
• Financial• Social support• Psychological support
Key points…• FMA is a condition resulting from maladaptive
neuroplasticity– Primary setting is recommended– Do not over medicalize patient
• Non-pharma strategies very important– Patient self management
• Symptom-based management– No ideal drug– Drugs show modest effects only
• Encourage retention in workforce• Relationship with a supportive PCP is crucial
True or False?
• Fibromyalgia is a diagnosis of exclusion. T/F
• Rheumatology referrals and/or extensive testing are required before one can make a definitive diagnosis of FMA. T/F
• I don’t have the time or skills to deal with Fibromyalgia patients. T/F
