Patient and Provider Education Fails to Improve Osteoarthritis Outcomes

A randomized trial of 537 knee osteoarthritis (OA) patients in the Duke Healthcare system has shown that patient- and provider interventions were no better than the usual standard of care.

Specifically, they compared a program of telephone-based patient intervention (weight management, physical activity, and cognitive behavioral pain management) to provider intervention (electronic delivery of patient-specific osteoarthritis treatment recommendations to providers who treat knee OA).

No intervention, whether patient-based, provider-based, or a combination of the two, provided improvements over usual care for patients with knee osteoarthritis. These findings contradict conclusions from an earlier study suggesting that a combined intervention provided modest improvements in function and activity compared with usual care. These results are published in Annals of Internal Medicine.

Managing pain and function associated with hip or knee osteoarthritis requires both medical and behavioral strategies, but recommended therapies are underused. A single-site study conducted in a Department of Veterans Affairs medical center showed that a combined patient and provider intervention improved outcomes for patients with knee osteoarthritis, but it did not assess separate effects of the interventions.

To examine whether patient-based, provider-based, and patient–provider interventions improve osteoarthritis outcomes, researchers randomly assigned 537 outpatients with symptomatic hip or knee OA treated in community-based primary care clinics to receive care using one of the three interventions - patient intervention, provider intervention or a combination of both approaches.

At 12 months, there were no significant improvements in WOMAC score for any of the intervention groups compared with usual care.

The authors note that the intervention was low-intensity. The authors suggest that higher-intensity interventions are needed to make more meaningful improvements in outcomes.

Should We Screen Younger Postmenopausal Women for Osteoporosis?

Do postmenopausal women, under age 65 years, need a baseline BMD testing? A JAMA Insights review suggests that the absolute risk of fracture is low in this group and that USPSTF guidelines should be considered - that we should be screening women younger than 65 years who are at increased risk of osteoporosis and we should be using a formal risk assessment tool to identify candidates for bone density testing.

Genicular Artery Embolization to Treat Osteoarthritis Knee Pain

A study from the Journal of Vascular and Interventional Radiology has shown that  knee pain secondary to osteoarthritis (OA) may be effectively treated by selective vascular interruption (embolization) showing efficacy and safety in a small pilot trial. 

ACR-Arthritis Foundation Treatment Guidelines for Osteoarthritis

Today, the American College of Rheumatology (ACR), in partnership with the Arthritis Foundation (AF), released the 2019 ACR/AF Guideline for the Management of Osteoarthritis of the Hand, Hip and Knee. The ACR periodically updates guidelines to reflect any advances in management added to the literature since the last publication, which in this case was 2012.

Short-term Benefit with Prednisolone in Hand Osteoarthritis

Lancet reports that prednisolone 10 mg daily for 6 weeks can effectively control the pain of hand osteoarthritis (OA), according to results from the Hand Osteoarthritis Prednisolone Efficacy (HOPE) study. This was a double-blind, randomized, placebo-controlled trial aimed to assess the short-term effects of prednisolone in painful hand OA and synovial inflammation. Patients were required to have hand OA and signs of inflammation in their distal and proximal interphalangeal (DIP/PIP) joints and > 4 DIP/PIP osteoarthritic nodes and at least one DIP/PIP joint with soft swelling/erythema or evidence of synovitis on power Doppler ultrasound. The primary endpoint was finger pain.
