Improving Current General Practitioners Care: Feasibility and Effectiveness of a Simple Educational Intervention. Knee Osteoarthritis Care: a Quality Improvement in General Practice

In Belgium, referral rates to physiotherapy of patients with knee osteoarthritis are low. A surveys shows that only 11% of the patients with knee osteoarthritis are referred for physiotherapy in an early stage of the disease process. Referral to physiotherapy is common after arthroplasty for revalidation, but not in early stage of the disease process. The aim of this study is to increase the referral rate for physiotherapy in an early stage of the disease process.

One to three times a year, a large part of Belgian GPs receive an academic detailing visit by an independent medical visitors of Farmaka. Farmaka is a non-profit organization, which is sponsored by the government. Each year, three medical and medication-related themes are developed to provide evidence-based and independent information for primary care management. A visit takes about 20 minutes.

The medical visitors of Farmaka will spend 5 minutes of their standard visit to inform GPs about the evidence-based conservative management of knee osteoarthritis with physiotherapy. The information will focus on the referral of patients with knee osteoarthritis to a physiotherapist in an early stage of the disease. To optimize the effect of the referral to physiotherapists, GPs are asked to specify their prescription by adding a clear therapy description 'exercise therapy with aerobic, muscle strengthening and functional exercises'.

This information will be summarized on a flyer. This flyer will be distributed to the GPs at the end of the academic detailing visit. The flyer gives more extended information about the approach and treatment of knee osteoarthritis. The information and flyer will only be distributed to the intervention group.

For the sample size calculation we want to optimize the referral rate to physiotherapists with 15%.
