In this issue of JointHealth™ monthly, we take a closer look at the most current research and models of care around three types of autoimmune arthritis—rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA)—through a new Canadian research study called
Ankylosing spondylitis is an inflammatory arthritis that affects up to 1 in 200 people. It primarily affects the spine, but can also involve the hips, knees, shoulders, and rib cage. Long-term back pain and spinal stiffness often occur with AS. AS is often misdiagnosed as ordinary "low back pain".
Ankylosing spondylitis is now considered to be one of two types of axial spondyloarthritis (axSpA). The other is non-radiographic axial spondylitis (nr-axSpA). The latter disease is considered to be an earlier form of AS (even though it may not become AS later) before structural changes to the sacroiliac joints show up on an X-ray. Otherwise, the signs and symptoms of the two diseases are similar. Clinically, the distinction is recognized; however, provincial medication formularies have not yet caught up with the new definition.
Rheumatoid arthritis is an autoimmune disease where the body's immune system mistakenly attacks its own healthy joints. The disease process causes swelling and pain in and around joints and can affect the body's organs including the eyes, lungs, and heart. Other joints that are commonly affected by RA are the hands and feet, elbows, shoulders, neck, jaw, ankles, knees, and hips. Approximately 300,000, or 1 in 100 Canadians live with RA.
Psoriatic arthritis is a form of inflammatory arthritis which causes swelling and pain in and around joints, as well as a scaly rash on the skin. The joints most commonly affected are the fingers, wrists, toes, knees, shoulders, elbows, and ankles. PsA also affects the tendons and ligaments around the joints.
It all started last summer in Vancouver with research stakeholder roundtable discussions on how inflammatory diseases including rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis can lead to complications such as heart attacks, strokes, lung clots, infections leading to hospitalization, osteoporotic hip fractures, specific malignancies, diabetes mellitus, and chronic obstructive pulmonary disease.
Roundtable participants spoke about how it is becoming increasingly clear that individuals with chronic inflammatory conditions display significantly shorter life expectancy and suffer from severe complications, chief among them heart attacks, strokes, lung clots.
At the roundtables, researchers and informed patients theorized that improving treatment of inflammatory disease could lead to reduced patient morbidity and mortality, and healthcare costs. These discussions gave birth to the formation of a multi-disciplinary team and research project called "PRECISION: Preventing Complications from Inflammatory Skin, Joint, and Bowel Conditions."
What sets PRECISION apart is that most previous research has treated arthritis complications as though they were comorbidities (the presence of one or more diseases, or disorders, in addition to a primary disease), rather than the direct result of chronic inflammation. Instead, the PRECISION study treats complications in a new way–that is, by seeing them as caused by inflammation. If correct, then complications are potentially avoidable, and researchers can begin to design programs to reduce or eliminate their occurrence.
The PRECISION project will study more than 600,000 (of the 5 million) Canadians with any of the following eight chronic inflammatory disease: psoriasis, rheumatoid arthritis, systemic autoimmune rheumatic disease, ankylosing spondylitis, gout, osteoarthritis, Crohn's disease and ulcerative colitis. The aims of the project are to:
- Evaluate and prevent inflammatory complications.
- Assess the exact role of inflammation in causing various complications.
- Test pilot health interventions to reduce or prevent complications using pharmacists, primary care physicians (PCPs) and case managers (a person who helps to identify available resources within the healthcare system, with the goal of enabling clients to lead a healthy life in the context of their chronic disease).
- Develop tools to improve patient self-management by monitoring physical activity through wearable digital technology, like fitness wristbands or bracelets.
- How common and how costly complications from inflammatory disease may be.
- What predicts which patients will develop a complication from these diseases.
- The effectiveness of new ways to diagnose and treat inflammatory diseases.
- Why Aboriginal communities have a higher chance of developing arthritis and why the severity of disease is more severe.
- Why women have a greater risk of developing chronic inflammatory conditions/diseases.
- Which types of physical activity help people with inflammatory diseases.
Arthritis Consumer Experts (ACE) is a proud collaborator of the PRECISION study. One of our first activities was to conduct a PRECISION survey to obtain an arthritis consumer viewpoint on arthritis, inflammatory bowel disease, and skin diseases. People living with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, lupus and lupus-like diseases, gout, osteoarthritis, inflammatory bowel disease (Crohn’s and ulcerative colitis), or skin diseases (psoriasis) responded to the PECISION survey. In a span of three three weeks, there were a total of 636 respondents.
Most respondents were women and had arthritis or other forms of chronic inflammatory disease. Below is a breakdown of disease representation within the survey respondents:
When it comes to managing their disease, most respondents took more than one medication and worried about side effects. Eighty-four percent of the respondents preferred to manage their disease with a healthy lifestyle. In comparison, only 16 percent preferred to manage their disease with medications.
It is important to remember that the survey respondents' responses were related to their concerns about potential side effects from a medication, not ones they were currently experiencing themselves. Also, we remind our readers that depending on the severity of a person's disease and their doctor's diagnosis, maintaining a healthy lifestyle may not be sufficient on its own and medication may be required to treat and manage their disease.
97.5 % of respondents believed it was important to invest in research on medications for decreasing heart attacks, leg clots or premature death, all of which are consequences of chronic inflammatory diseases.
Although medication adherence is a key factor in chronic disease management, nearly 58% of respondents were not interested in ways to help them remember taking medications as prescribed or on time.
Whether it is voluntary or involuntary, whether it is not filling a prescription to begin with, skipping doses, missing refills, or discontinuing medications altogether, patients not taking medications properly happens every day. This can result in negative outcomes such as unnecessary worsening of symptoms or progression of the condition, increased healthcare visits, the need for more medications or hospitalizations, and even an increased risk of death. Studies have shown that non-adherence to long-term therapy contributes to an increased burden on healthcare. According to a World Health Organization (WHO) report entitled "Adherence to long-term therapies: evidence for action 2003", the findings include:
- Adherence levels can fall quickly after starting therapy.
- Adherence to long-term therapy for chronic illnesses in developed countries averages only 50%.
- Non-adherence wastes resources, represents a missed opportunity for therapeutic benefit, and is associated with poorer patient outcomes.
- Non-adherence is a leading cause of preventable morbidity, mortality, and cost.
Dr. De Vera cites numbers that are truly scary:
- $7 - 9 billion: the estimated annual cost of non-adherence in Canada in 1995.
- $300 billion: more recent cost estimates from the United States.
- 69%: the proportion of medication-related hospitalizations due to non-adherence.
- 125,000: the number of unnecessary deaths per year due to non-adherence.
According to Dr. De Vera, "Medication non-adherence is truly an epidemic and as a pharmacoepidemiologist, my research program is focused on moving toward multi-disciplinary approaches to understanding and solving this health problem. It will take engaging patients, physicians, pharmacists, other healthcare professionals, and policy makers to build multi-disciplinary teams and provide unique perspectives to the problem. It will take involving not just patients but their support network. It will take borrowing tools from other disciplines and bringing them together. It will take the willingness to create new knowledge."
An exciting piece of the PRECISION study is the piloting of interventions to reduce the burden of complications from chronic inflammatory disease such as rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis. The PRECISION team will look at three pilot interventions:
- For pharmacists to educate and follow up with patients to increase medication compliance.
- For primary care physicians to increase screening of complications using digital technology such as e-reminders.
- For case managers in Aboriginal communities to facilitate integrated care of people with chronic inflammatory conditions.
