Clinical Utility Evidence for TissueCypher®

N/ACompletedNCT05200325

Qure Healthcare, LLC280 enrolled

Overview

Cernostics has developed a new diagnostic test, and this study will measure how gastroenterologists and foregut surgeons make diagnostic and treatment decisions when presented with different information in the context of simulated clinical cases. 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 provided to all participating physicians and submitted to a national journal for publication. The study plans to enroll up to 249 physicians.

Outcomes

Primary Outcomes

Clinical Performance and Value (CPV)-measured change in physician behavior

Change in the overall and the diagnostic and treatment evidence-based quality scores in the CPV patient simulations: difference-in-differences regression analysis between the control and the intervention groups' diagnosis and treatment of risk progression in patients with Barrett's esophagus, 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.

Time frame: 4 months

CPV-measured evidence based management decisions

Evidence-based management decisions based on patient's TissueCypher® test result: Once the intervention group is exposed to the intervention, education materials on the TissueCypher (a validated diagnostic test for predicting risk progression of BE patients), the scores are measured, on a scale of 0% to 100% from round 1 (pre-exposure) to round 2 (post-exposure) and observe how the evidence-based TissueCypher results influence physicians' management decisions.

Time frame: 4 months

CPV-measured cost savings

Change in cost of BE-related care. (This cost is modeled in part by measuring differential rates of endoscopic work up/interventions/levels of care selected by each arm, and multiplying by average Medicare reimbursement rates for these workups/interventions/levels of care. The cost is also modeled by examining average per annum costs for patients suffering from BE, and multiplying by the percent of patients whose workup or therapeutic management is significantly reduced following the intervention.)

Time frame: 1 month

Secondary Outcomes

CPV-measured baseline levels of variation

Participants completing the simulated cases, or CPVs, receive scores, on a scale from 0% to 100%, 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. Baseline levels of variation will be measured in the surveillance, management and treatment of patients with Barrett's esophagus among all participants
