Primary Outcome Measures:
  • Pain [ Time Frame: Baseline and 12-month follow-up ]
    Arthritis Impact Measurement Scales-2 (AIMS2), which consists of five items assessing typical pain, pain severity, and pain during specific times of the day, using a 5-point Likert scale ("all days" to "no days"). The possible range of scores is 0-10, with higher scores indicating more severe pain.

Secondary Outcome Measures:
  • AIMS 2 Physical Function [ Time Frame: Baseline and 12-month follow-up ]
    The AIMS2 physical function subscale includes 28 items that measure aspects of mobility, walking and bending, hand and finger function, arm function, self-care, and household tasks. All items on the AIMS2 physical function subscale are measured on a 5-point Likert scale ("all days" to "no days"). Scores can range from 0-10, with higher scores indicating worse function.

  • AIMS 2 Affect [ Time Frame: Baseline and 12 months ]
    The AIMS2 affect subscale includes ten items that encompass mood and tension. All items on the AIMS2 affect subscale are measured on a 5-point Likert scale ("all days" to "no days"). Scores can range from 0-10, with higher scores indicating worse affect.

  • Arthritis Self Efficacy [ Time Frame: Baseline and 12 months ]
    The Arthritis Self-Efficacy Scale measures how certain patients are they can perform 8 specific activities or tasks, related to arthritis. Items are scored on a Likert Scale (1=very uncertain to 10=very certain), with total scores ranging from 1-10. Higher scores indicate greater arthritis self-efficacy.

Experimental: Osteoarthritis Self-Management
Osteoarthritis Self-Management
Behavioral: Osteoarthritis Self-Management
12-month intervention consisting of monthly phone calls about topics related to self-care for osteoarthritis. Also includes written educational materials on these topics. Participants set goals and action plans, with assistance from health educator, about managing their osteoarthritis.

Detailed Description:
Background / Rationale: Osteoarthritis (OA) is the one of the most common chronic conditions among veterans, and over half of VA health care users with OA report being limited in their daily activities because of joint symptoms. However, studies have not examined interventions to improve outcomes or quality of care among the large and growing number of veterans with OA. Telephone-based self-management interventions may be a cost-effective way to improve pain, physical function, and other outcomes in this patient population. Objective: The purpose of this study is to examine the effectiveness of a one-year telephone-based self-management intervention for veterans with hip or knee OA. The primary hypothesis is that the self-management intervention will result in a greater reduction in pain as compared to both usual care and attention control conditions. Methods: This will be a randomized control trial of 519 veterans at the Durham VAMC who have radiographic evidence and a physician diagnosis of OA of the hip or knee. Participants will be equally allocated to self-management, attention control, and usual care groups. The self-management intervention is designed to provide participants with key information about OA and its treatment and to enhance participants' self-efficacy for managing OA-related symptoms. This intervention will involve provision of written, audio, and video educational materials, as well as monthly telephone calls by a nurse. The nurse will guide participants in developing personal OA-related goals, as well as specific plans for meeting these goals. Other strategies for enhancing self-efficacy will include modeling and mastery of self-management behaviors, persuasion to adopt these behaviors, and reinterpretation of OA symptoms. The attention control group will receive written materials on health screening related topics (not OA-related), and the nurse will call participants on a monthly basis to discuss these materials. The primary outcome measure for this study will be self-reported pain (Arthritis Impact Measurement-2 (AIMS2) subscale), and secondary outcomes will be self-reported function (AIMS2 subscale), affect (AIMS2 subscale), and arthritis specific self-efficacy. Outcomes will be measured at baseline and following the one-year study period. Analysis of covariance will be used to compare primary and secondary outcomes between the intervention group and each of the control groups, adjusting for baseline measures, participant demographic and clinical characteristics. We will also examine the cost-effectiveness of the intervention. Impact: This study is significant because it examines a highly prevalent but understudied chronic illness among veterans. In addition, this OA self-management program will contribute to the VA health care system's specific mission to improve pain management through patient education and participation. The proposed self-management intervention will be low-cost and easy to disseminate within the VA health care system. Therefore it may be an important tool for improving outcomes, especially pain, among many veterans with OA.
