Boosting Exercise Adherence in Knee Osteoarthritis

Официальное название

Boosting Exercise Adherence in Knee Osteoarthritis (BOOST-OA)

Обзор

This project, conducted within the Department of Veterans Affairs Healthcare System (VHA), will test the effectiveness of an intervention to improve adherence to home exercise among Veterans receiving physical therapy (PT) for knee osteoarthritis (OA). The intervention, "Boosting Exercise Adherence in Knee Osteoarthritis" (BOOST-OA), has two phases. During the initiation phase (first 3 months of PT care), patients will receive tools and activities to address outcome expectations, action self-efficacy, goal-setting and monitoring. During the behavior maintenance phase (starting after PT care and continuing for 9 months), patients will receive health coaching calls that address satisfaction with outcomes, relapse prevention planning and independent monitoring. There are three main study aims: (1) examine improvements in patient outcomes, such as physical function, following BOOST-OA; (2) explore patient characteristics that lead to difference in reported improvements; and (3) interview participants and clinicians about their experience with BOOST-OA to inform future implementation.

Подробное описание

In this project, the investigators will test the effectiveness of a theoretically-informed, scalable intervention to enhance adherence to home exercise among Veterans receiving PT for knee OA. "Boosting Exercise Adherence in Knee Osteoarthritis" (BOOST-OA) includes components that address both exercise behavior initiation (conducted in conjunction with the PT episode of care) and maintenance (conducted after completion of PT care). Specifically, BOOST-OA includes: 1) Tools and activities woven into PT visits that address outcome expectations, action self-efficacy, goal-setting and monitoring (3-month behavior initiation phase) and 2) Health coaching calls that address satisfaction with outcomes, relapse prevention planning and independent monitoring (9-month behavior maintenance phase). This project is being conducted within the Department of Veterans Affairs Healthcare system (VHA). Specific aims are:

* Aim 1. Examine the effectiveness of BOOST-OA for improving physical function and other key outcomes among Veterans receiving outpatient PT for knee OA using a pragmatic cluster-randomized trial, with 8 VA PT clinics randomized to BOOST-OA vs. usual PT care (UC). Participants will be Veterans with symptomatic knee OA (n=360, 45 per site/180 per study arm). At BOOST-OA sites, behavior initiation components will be provided in conjunction with standard PT visits, and a health coach will deliver maintenance components via telehealth. * Aim 2. Explore patient characteristics associated with differential improvement following BOOST-OA via a machine learning approach using model-based recursive partitioning. All participant characteristics, social determinants of health (SDOH), and baseline levels of study outcomes will be included in these analyses. * Aim 3: Conduct qualitative analyses of Veteran and PT clinician experiences with BOOST-OA to inform future implementation. The investigators will conduct semi-structured interviews with Veterans (n=36 across BOOST-OA sites and a subset of UC sites) and PT clinicians delivering care to BOOST-OA participants (n=8-12) to understand acceptability, feasibility, and perceived efficacy of the program, as well as barriers and facilitators to program participation and implementation.

Вмешательства

• Поведенческое Usual PT Care (UC)
  UC will be delivered by trained clinicians at participating sites. The study team will provide clinicians with guidance and training to standardize core aspects of PT, aligned with best practice recommendations. Clinicians must provide enrolled Veterans with at least 4 PT visits, spaced at least weekly so that Veterans can practice home exercise and receive guidance in exercise progression. All PT visits must be completed within 3 months.
• Поведенческое BOOST-OA
  BOOST-OA includes components that are integrated into PT visits (concurrent), focused on behavior initiation, as well as components that occur after PT visits have ended (sequential), focused on behavior maintenance. Concurrent components will be delivered in conjunction with usual care PT visits. Clinicians must provide enrolled Veterans with at least 4 PT visits, spaced at least weekly. PT visits must be also completed within 3 months. Sequential components will be delivered by a health coach
