Pharmacist-initiated Intervention Trial in OsteoArthritis (PhIT-OA)

Osteoarthritis (OA) is a major public health concern. Currently, there are at least 3 million Canadians afflicted with this condition with a 50% increase predicted by 2020. It is estimated that 85% of Canadians are afflicted with OA by age 70. As such, using the current health care structure, it is doubtful that the health system can keep pace with this increasing demand. Alternative health care delivery strategies must be investigated.

The purpose of this study is to assess if a pharmacist-initiated intervention for individuals with knee pain with a high likelihood of knee OA will lead to an improvement in the quality of care for these individuals.

We are hopeful that results of this study will show better management of knee osteoarthritis by a pharmacist-initiated intervention (which means that it is the pharmacist who will start the process for an intervention that includes exercise and an educational program when compared to no intervention. If this is the case, by implementing the proposed intervention program, subjects could be diagnosed earlier, the burden of illness on individuals could be diminished through an appropriate intervention program, and economic savings could be embraced.

Hypothesis: Community pharmacists can identify patients with likely knee OA and initiate a multidisciplinary intervention that will improve quality of care and outcomes.

About this study

This will be a pilot study of a multidisciplinary intervention for individuals with knee pain with a high likelihood of knee OA that could be a model for other chronic diseases. The intervention will be multidisciplinary such that it will be initiated by community pharmacists with referral to a comprehensive OA treatment program at the provincial arthritis center involving physiotherapists. In addition, formal communication will be initiated with their family doctor. Those in the usual care group will receive an educational OA pamphlet. The primary objective of this pilot project is to determine the proportion of patients who meet the Arthritis Foundation's Quality Indicator Set for osteoarthritis in the treatment arm compared to those in the usual care arm. Specifically, this indicator set focuses on health service provision within the first few months of diagnosis which includes physical examination, radiographs, education, exercise, weight loss, assistive devices and pharmacologic therapy.

Treatment and study plan

Pharmacist-Initiated Intervention in OsteoArthritis (PhIT-OA)

Procedure

See Detailed Description.

Primary outcomes

  1. The primary outcome will be the difference in proportion of patients who receive ≥ 5 of the Arthritis Foundation's quality indicators during the six months of the study.

    Time frame: 6 months

  2. (Baseline, months 2 and 6 )

    Time frame: Months 2 and 6

Secondary outcomes

  1. There are four secondary outcome measures that will be compared between intervention and usual care subjects at baseline, months 2 and 6:

    Time frame: Months 2 and 6

  2. The difference in change of physical functioning (using the mean score from 17 questions from the WOMAC that are directed towards this construct) between intervention and usual care. This outcome has been used in recent, well-designed trials of OA.

  3. The difference in knee pain (as assessed by five questions on the WOMAC);

  4. The difference in Health Utilities Index Mark 3 (HUI3); and

  5. The direct medical resource utilization using a questionnaire validated for use in musculoskeletal diseases.
