The Socrates Project for Difficult Diagnosis at Northwestern Medicine

We recognize several important limitations to our care model that may represent barriers to establishing, maintaining, and evaluating a similar service at other institutions. For example, there are limitations and benefits of the CMR as point person for managing our consultations. While they are admittedly junior colleagues with limited experience, CMRs tend to be among the best-read and up-to-date clinicians in the hospital by virtue of their recent general-medicine training and identification as a top clinician and leader. Moreover, in their role with the Socrates Project, CMRs have more time to think, talk with patients, and review the medical record than other clinicians, who may be under pressure to see an increasing number of patients while billing at higher levels. Indeed, the Socrates Project CMRs have, on a number of occasions, been the team members who find the piece of data that no one else thought relevant.

Another factor that may limit establishment of a similar team at other institutions is our volunteer-based model. The Socrates Project members volunteer because they love clinical medicine and serve on the team without remuneration for professional effort. With the CMR role as a notable exception, pressure from achieving relative value unit targets, obtaining grant funding, and publishing primary research publications in their field may limit this care model, particularly when shifting from a clinical-only activity to one that also formally investigates the service’s process and outcomes.

Beyond our clinical objective, we hope that the Socrates Project will further the discovery and description of previously unrecognized disease processes. To that end, we are pursuing an institutional review board-approved protocol to perform a rigorous assessment of the Socrates Project’s process and outcomes, including a cataloging of case archetypes and the time to definitive diagnosis if a diagnosis is established. As we continue to collect data, increasing our referral network may also lead to refinement and improvement in diagnostic processes and outcomes. Over time, we expect that the diagnostic resources available to us will evolve. Utilizing collective intelligence has been shown to improve diagnostic accuracy,⁶ and emerging artificial intelligence technologies may improve diagnostic performance as well.^7,8 Most importantly, through this endeavor, we hope to serve less as an oracle and more as a humble Socratic consultant for clinicians working to reduce diagnostic uncertainty for their patients.
