About this study
Official title: Effects of Comprehensive Care for Knee Osteoarthritis (OA)
We will study 300 people with knee osteoarthritis (OA) who receive their medical care from a large health maintenance organization (HMO) in Indianapolis. Our study will evaluate a comprehensive plan for treatment of knee OA by primary care physicians. Primary care physicians will provide standard care for knee OA to half of the study participants (150 people), and will use the comprehensive treatment plan guidelines to treat the other half. The comprehensive plan includes careful use of medications along with non-drug approaches such as patient education, exercise, and social support. People who participate in the study will receive care for knee OA for 1 year. We will measure the results (outcomes) of treatment at the start of the study and at 3 months, 6 months, and 12 months after patients join the study. The results we will measure include joint pain, physical function, drug side effects, quality of life, satisfaction with OA care, and the cost of medical care.
Read the detailed description
Anticipating trends toward generalism in medicine, the rheumatology community has begun to set forth guidelines for managing osteoarthritis (OA). These guidelines emphasize a comprehensive approach toward nondrug treatment (e.g., patient education, exercise, social support) and a conservative approach to drug management to minimize the side effects of nonsteroidal anti-inflammatory drugs (NSAIDs). Unfortunately, few primary care physicians provide conservative, comprehensive care for OA as promoted in the recent rheumatology literature. Also, although researchers have studied individual elements of a comprehensive approach to OA care and largely validated them in isolation, no research support exists to suggest that uniformly adopting OA care guidelines will result in better patient outcomes and/or reduced costs of care.
In this project, we will implement, in a controlled fashion, and evaluate a comprehensive plan for treating patients with knee OA by primary care physicians in a managed care environment. Comprehensive care for knee OA will be guided by a procedure designed to introduce and reinforce (a) an array of nondrug, self-care procedures intended to combat joint pain and preserve function and (b) a stepped protocol for drug management of knee pain that minimizes the risk of adverse side effects of NSAIDs.
Participants will be 300 patients with a confirmed clinical diagnosis of knee OA who receive their medical care in a large health maintenance organization (HMO) in Indianapolis, Indiana. We will randomly allocate geographically discrete offices of the HMOs to experimental (OA care by algorithm) or control (routine OA care) conditions (150 subjects/group). Patients who enroll in the study at each location will receive care for knee OA for 1 year under the guidelines specified by random assignment.
We will measure outcomes at baseline and 3 months, 6 months, and 12 months after enrollment, and outcomes will include joint pain, physical function, drug side effects, quality of life (i.e., general health status), satisfaction with OA care, and direct costs of medical care. We think that comprehensive care, as guided by our algorithms, will result in significant improvement in knee pain, physical function, and patient satisfaction, and lower direct costs compared to care delivered under routine circumstances.

The record says: finished, as of the sponsor's last update on 30 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00000404, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2013.
