 Results of needs assessment
 Burden of arthritis
 Approach to arthritis
 Polyarthritis

Acute vs. chronic

The Arthritis Expert Program:
Why?
 Many communities in SW Ontario are underserviced
in terms of arthritis care
 Arthritis Experts (AEs) will better support local health
teams in their delivery of complex medical care
 Comprised of nurses, nurse practitioners and family
physicians who frequently refer patients to
rheumatologists at St. Joseph’s Health Care (SJHC) in
London
The Arthritis Expert Program:
What?
 Will occur over 18 months, with monthly sessions
 Participants may attend sessions at SJHC or attend
monthly telemedicine conferences via computer
 At the end of the program, we expect that participants
will able to:
 Identify and triage rheumatologic complaints
 Confidently treat some complaints
 Co-manage chronic arthritic complaints in conjunction
with rheumatologists at SJHC
Course Curriculum
 Teleconferences / Broadcasting from Telehealth, to be
archived for use for those who can’t attend live
 Knowledge assessments – at the beginning and
throughout the program
 Preceptorships and rounds in some regions – also
telecast
 Case of the month – each month a case related to the
learning will be posted with each candidate giving the
answers, and then answers are posted and discussion
can occur
Course Curriculum
 Internet discussion board
 Chart audit –10 MSK patients sometime in first 6
months, with data extraction tool, to be done 3 times
over the course
 Attendance at the Education Day (live or via broadcast
/ DVD) once over the course – offered at various times,
usually on a Thursday, scheduled well in advance
 Opportunity to do advanced training preceptorship in
London (not mandatory)

General Arthritis Statistics in
Canada
 4 million Canadians have some form of arthritis (1 in 6
people).
 2/3 are women
 3 in 5 are <65 years old
 By 2026, 6 million Canadians will have arthritis.
 One of the top 3 most common chronic conditions
(with non-food allergies and back problems).

The Burden of Arthritis
 Major outcome of arthritis:



chronic pain
reduced mobility
decreased level of function
 Impact on quality of life: mobility, communication,
schooling & employment.
 Cost of arthritis was over $4 billion (1998) in health care
expenses and loss of productivity.
 In 1998, medication accounted for $270 million, or 6% of
total arthritis cost. This will increase with the use of
biologics.
The Arthritis Society of Canada. Arthroscope. An Ongoing Challenge, 2004.
A Chronic and Disabling Disease
 Compared to patients with other chronic conditions,
those with arthritis:
 Experienced more pain, activity restrictions & long-term
disability
 Were more likely to need help with daily activities
 Reported worse self-rated health, more disrupted sleep
and depression
 Have more contacts with healthcare professionals

Common Comorbidities in
Rheumatic Disease
• CVD & Atherosclerosis
• Metabolic Syndrome
• Fibromyalgia
• Peridontal Disease
• Effects of Smoking
Impact of Comorbidities
 Poorer outcomes (response, remission)
 Higher morbidity
 Increased mortality (e.g., CVD)
 Potential for drug interactions

Degenerative vs. Inflammatory
 The problem with inflammatory arthritis is in the
lining (synovium) of the joint
 The problem with degenerative arthritis is in the
cartilage
Approach To Polyarthritis
 What is polyarthritis? How is it different from
polyarthralgia?
 Polyarthritis: swelling, tenderness and warmth of >4
joints, demonstrated by physical examination
 Polyarthralgia: pain in >4 joints without demonstrable
inflammation on physical examination

What do you want to do?
 Aspirate the joint (i.e. take a sample of fluid from
the joint)
 IF THE JOINT IS RED, THE TUBES GET FED!
What do you send the fluid for?
 The 3 C’s
 Cell Count: A couple of hours
 Culture & Sensitivity: 24-48 hours
 Crystals: A couple of hours
 Gram Stain
Septic Arthritis
Acute Bacterial Arthritis
Medical emergency!!
Importance Of Diagnosis

Failure to recognize and appropriately treat
bacterial septic arthritides may lead to
significant rates of morbidity and even
mortality

Specifically, debilitating destruction of the
joint
Importance Of Diagnosis

Failure to recognize and appropriately treat
bacterial septic arthritides may lead to
significant rates of morbidity and even
mortality

Specifically, debilitating destruction of the
joint
Historical Features


Acute onset of joint pain (may be
superimposed on chronic pain)
History of trauma




Remember iatrogenic  joint aspiration
Monoarticular vs. polyarticular
Extra-articular symptoms
IV drug use/presence of intravenous
catheters
Historical Features


Exposure to STDs
Conditions that may decrease patient’s
immunity

Liver disease, DM, cancer, complement
deficiencies, hypogammaglobulinemia,
immunosuppressive medication
Historical Features


Classically, present with complaints of low
grade fever (40-60%), pain (75%) and
decreased ROM, evolving over days or
weeks
Sometimes difficult to distinguish from the
presentation of crystal arthropathies

Tend to have spiking fevers and chills, rigors
Historical Features


If prosthetic joint infection, course usually
low-grade with gradually increasing pain
Usually no significant swelling or fever



S. aureus associated with a fulminant course
Devitalized tissues (i.e. hematomas) more
susceptible to bacterial multiplication
Course usually more muted in case of
bacteremic spread
Historical Features

Tuberculous arthritis has indolent features

Usually negative PPD, no signs of past or
present pulmonary TB
Physical Findings

Most commonly involved joints: knee
(50%), hip (20%), shoulder (8%), ankle
(7%), wrists (7%)

Elbow, interphalangeal, sternoclavicular, SI
joints 1-4% cases
Physical Findings






Erythema and swelling in 90% of cases
Warmth and tenderness also essential for
diagnosis
Usually an obvious effusion
Marked limitation of PROM and AROM
Beware of locations where difficult to find: spine,
hip, shoulders
Physical findings muted in elderly,
immunocompromised, IVDU and especially those
with RA
Differential Diagnosis




Crystals (gout, pseudogout)
RA
Seronegative disease (PsA, enteropathic
arthritis)
Reactive arthritis
Rheumatic fever
Drug-induced arthritis
Diagnosis: Acute Gout
 The Disease of Kings
 Acute inflammatory arthritis
caused uric acid crystal
deposition in the joint
Who gets Gout?
 First attack in men between the ages of 35 and 50.
 In women it starts after menopause as estrogen
has a protective effect on the excretion of uric
acid.
Clinical Features of the Attack
 Starts quickly and very intensely – over a few hours
 Very painful (Can’t stand the bed sheets touching it)
 Swollen, warm, and red
 May feel unwell and have an associated fever
 i.e. it can look just like an infected joint!
What Joints does it affect?
 Usually a single joint in the
lower extremity
 First metatarsophalangeal
(MTP) joint (i.e. the big toe) is
affected in 50% of cases
Common Risk Factors for Gout
 Impaired renal function
 Diuretics: Lasix & hydrochlorothiazide
 Excessive Alcohol Intake
 Family history
 Male Sex
Other Disease Associations
“A Disease of Plenty”
 Obesity
 Hypertension (high blood pressure)
 Diabetes
 Hyperlipidemia (high lipids)
What “triggers” the Attack?
SMARTS
 Surgery
 Mechanical Injury
 Alcohol
 Recent Illness
 Travel / dehydration
 Start/Stop Allopurinol
How to Confirm the Diagnosis
 Must aspirate the joint and find urate crystals to
prove diagnosis (needle shaped)
 Urate crystals negatively birefringent in polarized
light
What Blood Tests Should I Order?
 Complete Blood Count (CBC)
 May see elevated WBC
 May see reactive thrombocytosis (increased platelets)
 Creatinine (measure renal function)
 Uric Acid
 Levels may be normal during an acute attack
 Fasting Glucose
 Fasting Lipid Levels
 Tryglycerides & cholesterol
A Word About Uric Acid
 There are lots of people walking around with elevated
uric acid levels (hyperuricemia)
 Many of these people will not get gout
 Hyperuricemia CANNOT be used to make a diagnosis
of gout!
 Do not treat isolated hyperuricemia
Treatment: Non-Pharmacologic
 Rest, ice, and elevate the Joint
 Dietary modification
 Meat & seafood are Bad
 Vegetables & low-fat dairy are good
 Reduce alcohol intake
 Good hydration
Pharmacologic
 Intra-articular corticosteroids
 Inject the affected joint
 Oral NSAIDs or COXIBs
 Indomethacin 50 mg PO TID
 Oral colchicine
 0.6 mg PO q8h
 Oral prednisone
 50 mg po x 7 days
When To Consider Allopurinol
1.
2.
3.
4.
Recurrent acute episodes of gout affecting lifestyle;
Patients at risk from complications of treatments
required for acute attacks;
Patient acceptance of the need for lifelong
medication compliance;
Uric acid tophaceous deposits
Allopurinol
 Do not start during an acute attack
 Prophylaxis with an NSAID/Colchicine
 Reduce uric acid to lower limit of laboratory reference
range
Xanthine
Uric Acid
Xanthine Oxidase
ALLOPURINOL
inhibits
Diagnosis: Acute Pseudogout

Acute inflammatory
arthritis caused by calcium
pyrophosphate crystals
Who gets Pseudogout?
 Older individuals
 Often have associated osteoarthritis
Clinical Features of the Attack
 Starts quickly and very intensely
 Tends to be less intense than gout and takes longer to
reach peak than acute gout
 Very painful
 Swollen, warm, and red
 May feel unwell and have an associated fever
 i.e. it can look just like an infected joint!
What Joints Does it Affect?
 Usually a single joint in the
lower extremity
 Knee is the most common
How to Confirm the Diagnosis
 Must aspirate the joint and find intracellular
calcium pyrophosphate crystals to prove diagnosis
(rhomboid shaped)
 CPP crystals positively birefringent in polarized
light
Non-Pharmacologic Treatment
 Rest, ice, and elevate the joint
 Good hydration
Pharmacologic
 Intra-Articular
Corticosteroids
 Inject the affected joint
 Oral NSAIDs or COXIBs
 Indomethacin 50 mg PO TID
 Oral Prednisone
 50 mg po od x 7 days
Summary
 We hope to increase teamwork between NPs, FPs and
rheumatologists
 Co-management of chronic disease
 Continuing education
