Resolving the Burden of Low Back Pain in Military Service Members and Veterans (RESOLVE): Protocol for a Multisite Pragmatic Clinical Trial

The Influence of Active, Passive, and Manual Therapy Interventions for Low Back Pain on Opioid Prescription and Health Care Utilization

OBJECTIVE

The aim of this study was to explore associations between the utilization of active, passive, and manual therapy interventions for low back pain (LBP) with 1-year escalation-of-care events, including opioid prescriptions, spinal injections, specialty care visits, and hospitalizations.

METHODS

This was a retrospective cohort study of 4827 patients identified via the Military Health System Data Repository who received physical therapist care for LBP in 4 outpatient clinics between January 1, 2015 and January 1, 2018. One-year escalation-of-care events were evaluated based on type of physical therapist interventions (ie, active, passive, or manual therapy) received using adjusted odds ratios.

RESULTS

Most patients (89.9%) received active interventions. Patients with 10% higher proportion of visits that included at least 1 passive intervention had a 3% to 6% higher likelihood of 1-year escalation-of-care events. Similarly, with 10% higher proportion of passive to active interventions used during the course of care, there was a 5% to 11% higher likelihood of 1-year escalation-of-care events. When compared to patients who received active interventions only, the likelihood of incurring 1-year escalation-of-care events was 50% to 220% higher for those who received mechanical traction and 2 or more different passive interventions, but lower by 50% for patients who received manual therapy.

CONCLUSION

Greater use of passive interventions for LBP was associated with elevated odds of 1-year escalation-of-care events. In addition, the use of specific passive interventions such as mechanical traction in conjunction with active interventions resulted in suboptimal escalation-of-care events, while the use of manual therapy was associated with more favorable downstream health care outcomes.

IMPACT

Physical therapists should be judicious in the use of passive interventions for the management of LBP as they are associated with greater likelihood of receiving opioid prescriptions, spinal injections, and specialty care visits.

Spinal magnetic stimulation to treat chronic back pain: a feasibility study in veterans

Aim: Chronic low back pain represents a significant societal problem leading to increased healthcare costs and quality of life. This study was designed to evaluate the feasibility and effectiveness of non-invasive spinal electromagnetic simulation (SEMS) to treat nonspecific chronic low back pain (CLBP). Methods: A single-site prospective study was conducted to evaluate SEMS in reducing pain and improving disability. A total of 17 patients received SEMS two to three sessions a week. The Numeric Rating Scale and the Modified Oswestry Disability Questionnaire were used to assess pain and disability. Results: Participants receiving SEMS exhibited statistically significant reductions in pain and disability. Conclusion: Current results suggest that non-invasive SEMS can be an effective treatment in reducing pain and improving disability associated with CLBP.

Intervention Fidelity in Pain Pragmatic Trials for Nonpharmacologic Pain Management: Nuanced Considerations for Determining PRECIS-2 Flexibility in Delivery and Adherence

Nonpharmacological treatments are considered first-line pain management strategies, but they remain clinically underused. For years, pain-focused pragmatic clinical trials (PCTs) have generated evidence for the enhanced use of nonpharmacological interventions in routine clinical settings to help overcome implementation barriers. The Pragmatic Explanatory Continuum Indicator Summary (PRECIS-2) framework describes the degree of pragmatism across 9 key domains. Among these, "flexibility in delivery" and "flexibility in adherence," address a key goal of pragmatic research by tailoring approaches to settings in which people receive routine care. However, to maintain scientific and ethical rigor, PCTs must ensure that flexibility features do not compromise delivery of interventions as designed, such that the results are ethically and scientifically sound. Key principles of achieving this balance include clear definitions of intervention core components, intervention monitoring and documentation that is sufficient but not overly burdensome, provider training that meets the demands of delivering an intervention in real-world settings, and use of an ethical lens to recognize and avoid potential trial futility when necessary and appropriate. PERSPECTIVE: This article presents nuances to be considered when applying the PRECIS-2 framework to describe pragmatic clinical trials. Trials must ensure that patient-centered treatment flexibility does not compromise delivery of interventions as designed, such that measurement and analysis of treatment effects is reliable.
