Establishing Clinical Utility Evidence for Chronic Disease Management Testing

Establishing Clinical Utility Evidence for Chronic Disease Management Testing (CDMT): A CPV® RandomizedControlled Trial

This is a national-level research study of primary care physicians. The purpose of this study is to assess the clinical evaluation and management (drug, procedures, counseling and other) of a subset of common patient care indications.

Study Overview

• Status: Completed
• Conditions: Cardiometabolic Syndrome
• Intervention / Treatment: Other: Educational Materials and Chronic Disease Management Test (CDMT)

Detailed Description

The results of this study could contribute to improved quality of care for patients by encouraging better care practices and adherence to evidence-based guidance. The data from this study will be submitted to a national journal for publication. The study plans to enroll up to 300 physicians.

Upon consenting and agreeing to participate in this study, participants will be asked to care for 3 simulated patient cases, known as Clinical Performance and Value Vignettes (CPV®). CPVs describe patients physicians typically encounter in their daily practice and are not meant to be difficult. In each vignette, physicians are asked to share their expected care through 5 domains: 1) history, 2) physical exam, 3) diagnostic workup, 4) diagnosis and 5) treatment and follow-up. Each case takes approximately 15-20 minutes to complete and we estimate the time commitment for each round of CPV administration to be approximately 45 - 60 minutes. All responses to the cases will be completed online and will be kept confidential. Over 2 CPV administration rounds, the total time to care for the simulated patients is estimated at 1.5-2 hours.

If physicians are randomized to an intervention group in this study, they will receive education materials on a diagnostic test currently available for use in the market after the first round of CPV administration. They are asked to review these materials before moving to the next CPV administration round. Time to review education materials is estimated to be approximately 15 minutes.

Depending on the results of this randomized controlled trial, there may be an opportunity for physicians to re-enroll into a follow-on study. If they choose to participate in this second study, they will be asked to identify and send de-identified records of patients in their practice that are similar to the simulated patients they previously cared for in this study.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: Control; These providers will complete two rounds of three simulated patient cases (CPVs). Control arm physicians will continue to have access to standard of care diagnostic tools, but not the CDMT test results.
Experimental: Educational Materials and CDMT Test Results (Intervention 1); Participants will care for the same set of CPV patients as the control arm, but will be educated on and will receive the CDMT test results whether they select it or not. Investigators will compare intervention participants' clinical recommendations to those in the control arm.	Other: Educational Materials and Chronic Disease Management Test (CDMT); Intervention-1- and Intervention-2-arm participants will receive educational materials duplicating what physicians would receive in the real-world market as they adopt the CDMT technology. These materials are comprised of a PowerPoint presentation. Intervention 1 participants only will receive the CDMT test results whether they select it or not, and Intervention 2 participants will receive the CDMT test results only if they select it during the second round of case simulations.
Experimental: Educational Materials and CDMT Test Results when Selected (Intervention 2); Participants will care for the same set of CPV patients as the control arm, but will be educated on and will receive the CDMT test results only if they select it. Investigators will compare intervention participants' clinical recommendations to those in the control arm.	Other: Educational Materials and Chronic Disease Management Test (CDMT); Intervention-1- and Intervention-2-arm participants will receive educational materials duplicating what physicians would receive in the real-world market as they adopt the CDMT technology. These materials are comprised of a PowerPoint presentation. Intervention 1 participants only will receive the CDMT test results whether they select it or not, and Intervention 2 participants will receive the CDMT test results only if they select it during the second round of case simulations.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
CPV-measured clinical score difference(drug, procedures, counseling and other)	Difference-in-differences regression analysis between the control and the intervention groups' diagnosis and treatment of chronic dyspnea, as measured by the participants diagnostic and treatment CPV case domain scores. In each domain of a CPV (history, physical exam, workup, diagnosis and treatment), participants' care recommendations are evaluated against evidence-based care scoring criteria which can sum from 0 to a high potential score of up to 100 percent in each domain, where higher scores mean better outcomes.	12 months
Test Adoption Rate	Rate of adoption of the CDMT test in Intervention 2 arm participants.	12 months
CPV-measured cost difference	Difference in expected cost of care between control and intervention participants. (Cost will be calculated by measuring differential rates of medical interventions/levels of care selected by each arm, and multiplying by Medicare reimbursement rates for these interventions, and/or by modeling the incidence of expected complications and calculating associated costs.)	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
CPV-measured clinical score differences by use case	Difference in the overall, and the diagnostic and treatment quality scores between control and intervention participants. Diagnostic and treatment scores are calculated as the percent correct on CPVs, and the overall score is a average score of the subcategory scores (percent correct). This will be examined for each of the use cases to determine in which case(s) CPV scores most improved.	12 months
CPV-measured cost differences by use case	Difference in expected cost of care between control and intervention participants. (Cost will be calculated by measuring differential rates of medical interventions/levels of care selected by each arm, and multiplying by Medicare reimbursement rates for these interventions, and/or by modeling the incidence of expected complications and calculating associated costs.) This will be examined for each of the use cases to determine in which case(s) cost metrics most improved.	12 months
CPV-measured baseline variation	Participants 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	12 months
