Does early, guideline-true physical therapy cut back-pain costs?
Among 753,450 MHS adults with new LBP, early guideline-adherent PT (17,175 people) tracked less imaging, injections, surgery, and opioids and about 60% lower 2-year LBP-related costs.

Study at a glance
- Design
- Cohort — Retrospective Military Health System cohort of new primary-care LBP visits (2007–2009) with 2-year utilization/cost follow-up.
- N
- N=753450 · 753,450 unique patients 18–60 after exclusions; 122,723 (16.3%) used PT within 90 days; 17,175 early + guideline-adherent.
- Population
- MHS beneficiaries aged 18–60 with a new primary-care low-back-pain visit (no LBP care in prior 12 months).
- Outcome
- 2-year advanced imaging, lumbar injections, lumbar surgery, opioid use, and LBP-related costs by PT timing and guideline adherence.

What they did
Identified new primary-care LBP visits 2007–2009, classified PT within 14 days as early (vs 14–90 days delayed), scored PT content as guideline-adherent active care, and compared 2-year utilization (adjusted ORs, 99% CIs) and costs.
What they found
16.3% used PT. Early vs delayed PT: imaging AOR 0.52, injections 0.56, surgery 0.59, opioids 0.62; LBP costs $1,828 vs $3,031 (about $1,202 lower). Adherent vs non-adherent care also cut imaging/injections/surgery (AORs 0.72–0.85) but not opioids.
The limits
What it doesn't show
Observational claims cannot prove PT caused the savings—healthier or more motivated patients may get early adherent PT; RCTs are still needed before policy mandates.
Key terms
- Early PT
- Physical therapy within 14 days of the primary-care index LBP visit.
- Guideline-adherent PT
- PT content matching active-treatment recommendations (not passive-heavy care).
- Military Health System (MHS)
- US single-payer system for active duty, retirees, and dependents (~10 million).
- Delayed PT
- First PT visit 14–90 days after the index primary-care visit.
- LBP-related costs
- Two-year back-pain spending; ~60% lower with early adherent PT in this cohort.

Common questions
How large was the cohort?
753,450 unique patients aged 18–60.
How many used PT?
16.3% (n=122,723) within 90 days.
Early vs delayed imaging AOR?
0.52 (99% CI 0.50–0.54).
Can this prove causation?
No—authors call for RCTs before definitive policy.
