Clinical Practice Guidelines for Neck and Low Back Pain in Outpatient Physical Therapy

Study Overview
=================
Brief Summary
-----------------
This study will investigate implementation of a process to enhance Clinical Practice Guideline (CPG) adherence to limit unwarranted variability in initial treatment decisions with high potential for providing more effective and efficient physical therapy management for patients with neck and low back pain.

Detailed Description
-----------------
Effective implementation of CPGs to augment initial clinical decision making during physical therapy management of patients with spine related musculoskeletal pain will have several important goals: 1) improve patient pain and disability outcomes, 2) limit over utilization of physical therapy services, and 3) increase adherence to limit unwarranted variation in clinical practice. This proposed pilot study proposal will test if a multifaceted intervention strategy for implementation of neck and low back CPG meets these goals and provide necessary data for larger system wide implementation efforts. Specific Aim 1: Determine if physical therapy clinics that receive neck and low back pain (LBP) clinical practice guideline (CPG) training are associated with improved patient outcomes compared to those that have not received training. Neck and LBP specific disability and pain intensity will be assessed at intake, on a weekly basis and at discharge (Specific Aim 1a). Secondary patient outcomes will consist of patient satisfaction scores (Specific Aim 1b). Statistical analyses will evaluate for temporal effects of training considering the stepped wedge study design. Specific Aim 2: Determine if multifaceted interventions for CPG implementation positively impacts physical therapist beliefs, attitudes, knowledge and behaviors over time. CPG adherence (by clinicians) will be indirectly assessed using quantitative and qualitative methods consisting of: 1) clinician checklists, 2) clinician questionnaires, 3) quality indicators, and 4) total proportion outcome measure assessments (Specific Aim 2).

Design Details

Primary Purpose: Health Services Research
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: cross-sectional stepped wedge design
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Physical Therapists - CPG<br>Cross-sectional stepped wedge design with 16 physical therapy clinics (including approximately 40 physical therapists) being allocated to one of 4 sequences that differ in CPG implementation time (each sequence consisting of 4 clinics). This proposed study will be conducted over 68 weeks, with the initial 12 weeks serving as a baseline washout phase (before any clinic has received training), then 4 clinics crossing over from standard care (control) to CPG and decision support tool implementation (intervention) approximately every 8 weeks until week 44 when all 4 sequences (16 clinics) have completed training. | Behavioral: Clinical Practice Guideline Implementation<br>* The Study team will use several methods from the implementation strategy taxonomy of the Effective Practice and Organization of Care (EPOC) classification system to improve our likelihood for successful neck and low back pain implementation consisting of: 1) educational materials, workshops and outreach visits from trainers; 2) external consultant testimonials; 3) iterative quality improvement processes (including ongoing analysis of clinician feedback to improve process); 4) routine collection of patient reported outcomes to engage discussion among clinician groups and outpatient division leaders) and 5) local organization consensus process (including feedback from key outpatient division stakeholders).<br>|
| Active Comparator: Physical Therapists - Control<br>This proposed study will be conducted over 68 weeks, with the initial 12 weeks serving as a baseline washout phase (before any clinic has received training), then 4 clinics crossing over from standard care (control) to CPG and decision support tool implementation (intervention) approximately every 8 weeks until week 44 when all 4 sequences (16 clinics) have completed training. | Other: Standard Care<br>* Considering the stepped wedge design with a 12-week washout phase, clinics will be providing standard physical therapy prior to receiving clinical practice guideline training.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Oswestry Disability Index (ODI) | The Oswestry Disability Index (ODI), which has 10 items that assesses how low back pain affects common daily activities. The ODI has a range of 0% no disability due to low back pain to 100% completely disabled due to low back pain, with higher scores indicating higher disability from low back pain. | 68 weeks | 
| Neck Disability Index (NDI) | The Neck Disability Index (NDI), which has 10 items that assesses how neck pain affects common daily activities. The NDI has a range of 0% no disability due to neck pain to 100% completely disabled due to neck pain, with higher scores indicating higher disability from neck pain. | 68 weeks | 
| Numeric Pain Rating Scale (NPRS) | Numeric Pain Rating Scale (NPRS) Pain intensity will be rated using a NPRS, ranging from 0 (no pain) to 10 (worst pain imaginable). Patients will be asked to rate their current pain intensity, as well as their best and worst level of pain intensity over the past 24 hours. These 3 pain ratings will averaged and used as the NPRS variable in this study. | 68 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rehabilitation Outpatient Division Patient Satisfaction Survey | To assess overall therapy experience and explanations provided by therapist. | 68 weeks | 
| Evidence-Based Practice Questionnaire (EBPQ) | The Evidence-Based Practice Questionnaire (EBPQ) to assess clinician beliefs, attitudes, knowledge and self-reported behaviors regarding evidence-based practice and clinical practice guidelines. Responses range from Strongly Agree to Strongly Disagree. | 68 weeks |
