Clinical Trial Summary

This study will collect high-quality data on how practicing primary care physicians across the U.S. currently manage patients experiencing chronic pain and how the results of Ethos Laboratories' test change clinical decision making. To do so, this study leverages simulated patient cases called Clinical Performance and Value vignettes (CPVs) in a proven methodology to rapidly measure physician care decisions.

Description:

This study will collect high-quality randomized controlled data from a nationally representative sample of practicing physicians, specifically primary care physicians and pain specialists, to determine how they currently manage patients with pain and how the results of Ethos' test change their clinical decision making. Data from this study will better illuminate the clinical use cases in which the Ethos test has the most significant impact on clinical decision making (and thus the largest clinical utility) and the physician characteristics (e.g., age, practice setting, training) associated with practice change.

The study is a prospective cohort trial with six steps:

1. Enrollment: The study will enroll an estimated 166 practicing primary care physicians who practice in the U.S. and are determined to be eligible by an eligibility screener.

2. Provider survey: Once providers are enrolled in the study, they will be asked to complete a questionnaire describing their practice and professional background.

3. Randomization: The 166 physicians will be randomized into equally-sized control and intervention arms.

4. CPVs (First Round): Physicians will complete three randomly-assigned CPV patient simulations. Cases will be identical across the intervention and control arms. All interactive cases are presented on an online platform, and are accessible via unique weblinks and any internet-connected computer.

5. Intervention education: Intervention-arm physicians will receive educational materials describing the clinical validation and use cases of the Ethos test. This material will replicate what physicians would receive as part of an actual marketing push introducing them to the Ethos test. These materials may be comprised of a slide deck, fact sheet, webinar, and/or case studies.

6. CPVs (Second Round): All participating physicians will then be asked to complete three additional CPV patient simulations. The cases are given to the doctors in a random order. Cases will be identical across the intervention and control arms, except that the intervention arm will receive Ethos test results at an appropriate point in each simulated case in the post-intervention round. Control arm physicians will continue to have access to standard of care diagnostic tools, but not the Ethos test results.

Related Conditions & MeSH terms

• Chronic Pain
• Pain
• Pain, Chronic

Intervention

Other:
• Experimental Arm
First, these providers will receive educational materials (e.g. a slide deck, mock test result and FAQ handout) meant to mimic what physicians will receive in the real-world market as they learn about the Ethos technology. Second, within each of their second-round cases, intervention-arm physicians only will receive simulated test results from the Ethos test at the clinically-appropriate point in each case.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	CPV-measured pre-/post-difference in quality score between intervention and control physicians	Physicians completing the simulated cases, or CPVs, receive scores based upon the quality of care they provide. This measure will assess the pre-/post-difference in these scores between control physicians using standard of care diagnostic tools and intervention physicians with access to Ethos test results, including by use case types	2-4 weeks
Primary	CPV-measured differences in evidence-based decisions made by intervention physicians and control physicians between rounds 1 and 2	Physicians completing the simulated cases, or CPVs, receive scores based upon the quality of care they provide. This measure will assess differences in evidence-based decisions made by intervention physicians and control physicians between rounds 1 and 2, including by use case types	2-4 weeks
Primary	CPV-measured cost difference	Difference in cost of care between control and intervention physicians, including by use case types. (Cost will be calculated by measuring differential rates of medical interventions/levels of care selected by each arm on their CPVs, and multiplying by Medicare reimbursement rates for these interventions, and/or by modeling the incidence of expected complications and calculating associated costs.)	2-4 weeks
Secondary	CPV-measured baseline variation	Physicians completing the simulated cases, or CPVs, receive scores based upon the quality of care they provide. This measure will assess the baseline levels of variation in the care of pain patients among all participants, including by use case types	1 week
