Study Arms:
- Stratified Care (Type: EXPERIMENTAL): In three Participating Sites from Family Medicine sites, the Keele STarT Back Screening Tool will be administered to patients with acute and chronic low back pain and based on patients' responses, patients will be stratified into one of three risk groups: low, medium or high-risk. Patients in the medium- and high-risk groups will be referred to physical therapy for a matched physical therapy (PT) intervention based on the risk strata. Patients in the low-risk group will be managed in Family Medicine with an intervention that includes advice, reassurance, patient education, and NSAIDs (with no referral for imaging or specialist care).
- Current Care (Type: ACTIVE_COMPARATOR): In three Comparator Sites from Family Medicine, providers will give the current care at The University of Vermont Medical Center for patients with acute and chronic low back pain.

Based on this trial design, predict the completion outcome and termination type (if applicable).
