Understanding Osteoarthritis

Prevalence

  • An estimated one in five adults in the United States has been diagnosed with arthritis.1
  • OA is the most common form of arthritis and ranks among the top three health conditions causing disability.2,3

Clinical Manifestations of OA

  • OA involves the release of inflammatory mediators by cartilage, bone, and synovium, and has been linked to many health conditions, including increased risk for cardiovascular disease.4-6
  • Symptoms include pain, swelling, and stiffness in the affected joints.

The Vicious Cycle of OA

  • Patients with OA often experience reduced mobility and challenges performing activities of daily living.
  • Patients often become sedentary and gain weight. 
  • Worsening mobility impairs patient function and further contributes to undesirable health conditions.
  • Physical impacts may include cardiovascular disease, diabetes, and some types of cancer.
  • Mental and psychological impairments may include depression, anxiety, and decreasing cognitive function.7
Connecting Patients with Treatment

In addition to having difficulty with function and mobility, patients with OA may have challenges with treatment, including:

  • Identifying and accessing appropriate treatment options.
  • Understanding the risks and benefits of pain medications.
  • Adhering to a pain management treatment plan.
  • Being at risk for the misuse or abuse of pain medications.

Research has found that involving pharmacists in the care of patients with OA can improve utilization of treatments, function, pain, and quality of life for their patients.8 Pharmacists can help patients:

  • Navigate treatment options.
  • Establish and attain functional goals.
  • Minimize factors that may lead to poor health outcomes.
  • Adhere to treatment recommendations.
Improving the Approach to Pain Management in Patients With OA

As a chronic painful condition, OA often requires a multifaceted approach that addresses a range of patient needs to maintain function and mobility. Components of treatment may include:

  • Appropriate pain management to attain goals of improved function, health, and quality of life.
  • Exercise to help control weight and maintain balance and mobility.
  • Weight loss, which is particularly beneficial for patients with OA because it reduces strain on weight-bearing joints, and obesity itself is a cause of inflammation that can contribute to OA.6
  • Educational programs and ongoing support.9

Many tools and resources are available to provide education and support for patients with OA. For example, links to useful resources from the Arthritis Foundation are available at www.arthritis.org/toolkits/arthritis-pain. Additionally, pharmacists can use motivational interviewing (MI) strategies to guide patients toward engaging in behaviors that will help them achieve their treatment goals.

Methods for Support: Motivational Interviewing

MI uses a patient-centered approach that acknowledges the patient’s expertise about his or her problems and empowers the patient to develop intrinsic motivation.10 Self-motivation is crucial when considering the importance of exercise and weight-loss in care plans for OA. Examples of MI strategies that pharmacists can use are shown in Table 1.

MI takes practice. The following resources provide additional guidance on this impactful method of communication:

Treatment Options for OA
OA should be managed through a holistic approach that considers patient comorbidities, medications, and risk factors. Early recognition and treatment with nonpharmacologic approaches can slow disease progression and lessen the need for long-term medications. The most appropriate interventions will depend on the joints affected, symptom severity, and other individual patient factors. Evidence-based nonpharmacologic recommendations include:11-17
  • Self-management programs and education
  • Weight loss, if body mass index ≥25
  • Joint protection (splinting)
  • Range of motion exercises
  • Low-impact aerobic exercise, including aquatic exercise
  • Strength training
  • Appropriate footwear
  • Physical therapy
  • Walking aids/assistive devices
  • Balneotherapy/thermal agents
  • Acupuncture
If nonpharmacologic treatments alone do not provide sufficient efficacy, pharmacologic treatments may be appropriate to help reduce pain and enable patients to maintain mobility, engage in physical activity, and break the vicious cycle of worsening pain and declining function. Table 2 provides guidance on pharmacologic treatments for OA, including their role in therapy, important counseling points, and which treatments should be used with increased caution.
