- Brief Summary
This study will examine the impact of a new clinical decision support tool for rehabilitation after total knee arthroplasty (TKA). Typically, TKA rehabilitation is generic with most patients receiving the same dosage and contents of rehabilitation despite notable diversity among patients who undergo TKA. The investigators clinical support decision tool is designed to help physical therapists tailor rehabilitation treatments and dosages to the individual needs, goals, and preferences of Veterans recovering from TKA. This study has the potential to improve Veterans' functional recovery after TKA, while simultaneously reducing the average number of physical therapy visits Veterans attend after surgery by tailoring rehabilitation dosage based upon need. This will ensure the Veterans Health Administration (VHA) has the resources and capacity to provide adequate rehabilitation to every Veteran seeking TKA in the VHA system. Additionally, if successful, this clinical decision support tool could be used to improve outcomes and access for additional patient populations in the future.
- Detailed Description
Rehabilitation after total knee arthroplasty (TKA) is typically generic and inefficient; most patients receive the same contents and dosage of rehabilitation regardless of the patients individual needs, preferences, or expectations. This generic treatment paradigm will be unsustainable in the Veterans Health Administration (VHA) as the demand for TKA surgery and postoperative care increase exponentially in the near future. Without new strategies to improve the efficiency of TKA rehabilitation, organizations like the VHA will struggle to meet and pay for this surging demand, and Veterans may be denied timely access to the postoperative care they need for optimal recovery. The investigators have developed an innovative new clinical decision support (CDS) tool to optimize efficiency in TKA rehabilitation. Using the actual recovery data of similar historical patients, the tool can predict the recovery trajectory for new patients after TKA. This allows clinicians to (1) allocate rehabilitation resources based upon individual need, (2) identify Veterans at risk for suboptimal outcomes early after surgery, (3) tailor treatment strategies to Veterans' unique goals and clinical presentation, and (4) monitor Veterans' recovery relative to expected throughout postoperative rehabilitation. In this project, the investigators propose to expand the CDS tool's capabilities by establishing utilization guidelines based upon individual Veteran's predicted recovery (Aim 1). These guidelines will be established by expert consensus in a three round Delphi process. Subsequently, the investigators will test the CDS tool's impact on Veteran's functional recovery and rehabilitation utilization in four VHA outpatient physical therapy clinics using a pre-post design (Aim 2). The investigators will compare patient-reported function (Lower Extremity Functional Scale) and physical therapy visit utilization between cohorts of Veterans treated with and without the CDS tool. Additionally, the investigators will gather data from participating VHA clinicians and Veterans regarding the translation of the investigators tool into clinical practice to assess its readiness for dissemination throughout the VHA (Aim 3). This will include qualitative data from participant focus groups and quantitative process data regarding the tool's utilization. Ultimately, the investigators expect this study will serve as a template for expanding the investigators tool's capabilities into numerous VHA populations in rehabilitation and beyond.

Group Intervention Description Intervention cohort Clinical decision support tool (CDS tool) The investigators will implement the clinical decision support tool in all participating clinic locations. We will collect outcomes for 100 Veterans treated in rehabilitation with use of the clinical decision support tool. Data collection for these Veterans will occur after data collection is complete for the Control cohort.
- Primary Outcome Measures
Name Time Method Outpatient Physical Therapy Visit Utilization Postoperative day 90 The total outpatient physical therapy visits used in the first 90 postoperative days by each Veteran participant will be extracted from the electronic health record after the Veteran is formally discharged from outpatient rehabilitation. Any visits that occur prior to a Veteran's surgery or in the hospital setting will not count toward the total visit number. We chose postoperative day 90 as our primary endpoint because it corresponds with the average discharge timeframe for outpatient rehabilitation after total knee arthroplasty. Visit utilization will also be assed at at 30, 60, and 180 days after TKA surgery.
Knee Injury and Osteoarthritis Outcome - Joint Replacement (KOOS, JR) Change in KOOS Jr from preop (baseline) to postop (90 days after TKA surgery) The KOOS-JR is a patient-reported measure of physical function developed specifically for patients with total knee arthroplasty. It can be completed quickly (only 7 items) and has established validity, reliability, and responsiveness. KOOS JR will also be assessed at 30, 60, and 180 days after TKA surgery. We will use the interval scoring method for the KOOS JR which ranges from 0 (total knee disability) to 100 (perfect knee health)
- Secondary Outcome Measures
Name Time Method Lower Extremity Functional Scale (LEFS) Change in LEFS from preop (baseline) to postop (90 days after TKA surgery). The LEFS is a generic scale of lower extremity physical function that has established validity, reliability, and sensitivity to change for patients with total knee arthroplasty. LEFS will also be assessed at 30, 60, and 180 days after TKA surgery. The LEFS scale ranges from 0 (lowest function) to 80 (highest function).
Knee range of motion (ROM) Change in knee ROM from preop (baseline) to postop (90 days after TKA surgery) Knee ROM will be measured manually by goniometry which is a valid and reliable technique for measuring knee mobility. Recovery of knee ROM after TKA is necessary for many functional activities and is emphasized in rehabilitation after total knee arthroplasty. ROM will also be assessed at 30 and 60 days after TKA surgery.
Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) Pain subscale Change in WOMAC pain subscale from preop (baseline) to postop (90 days after TKA surgery) The WOMAC pain subscale is a valid, reliable, and responsive measure of patient-reported pain for individuals with osteoarthritis of the knee. WOMAC pain subscale will also be assessed at 30 and 60 days after TKA surgery. The WOMAC pain subscale scores range from 0 (lowest pain) to 20 (highest pain).
Timed Up and Go (TUG) Change in TUG from preop (baseline) to postop (90 days after TKA surgery) The TUG is a basic measure of mobility and balance which consists of rising from a seated position, walking three meters, and pivoting and returning to the original seated position. The TUG is responsive to change with adequate reliability in the acute recovery period after total knee arthroplasty. TUG will also be assessed at 30 and 60 days after TKA surgery.
