🎙️ Out of the FHIR Podcast: Part 2 with Joshua Kelly – Highlights
🚀 What’s Joshua Excited About?
* Payer-to-Payer ExchangeA pivotal shift enabling payers to consume data—not just expose APIs—transforming how charts are transferred and reducing manual burden. Huge potential impact on chart chase inefficiencies and member onboarding.
* FHIR-Specific AI Model Evaluations (FIRE Evals)Joshua outlines Flexpa's work on evaluating LLMs for FHIR tasks like:
* Extracting structured data from FHIR resources
* Generating FHIR bundles from text
* Using reinforcement learning with verified rewards (not RLHF) to improve smaller, private models that outperform general LLMs in FHIR use cases
* FHIR validate operation as a reward signal in reinforcement learning, opening the door for better automated resource generation.
💡 Underrated Innovations
* Smart Health Cards & LinksJoshua sees these as massively underutilized. He envisions paper-based lab results with QR codes enabling seamless data transport—a simple but transformative workflow for patients and providers.
* Patient “Sneaker Net” as an Interop HackPatients as the natural transport layer—bringing their own data (e.g., via QR codes or printed links) could rival national HIE efforts in utility.
* ChatGPT for Patient InsightReal-world use: Eugene shares how he used GPT to interpret his child’s lab results. This is already happening—users are moving ahead of systems.
🏦 Financial Interop Lessons for Healthcare
* OAuth SuccessHealthcare learned from fintech, starting with OAuth, unlike fintech’s slow rollout.
* Why Plaid’s Model Doesn’t Fully Translate
* Fewer, more cohesive accounts in finance (e.g., Amex, Chase)
* Healthcare data is fragmented across insurers, providers, labs, often with confusing branding (e.g., the "Blue Cross problem")
* The Real Challenge? Data Locator ConfusionEven insiders can’t always identify where data lives. This limits the utility of personal health apps or wallets—too niche for mass adoption.
🔧 Tech That Needs More Love
* SQL-on-FHIRJoshua ranks this as his #2 underrated tech (after Smart Health Cards). While not truly “SQL,” it simplifies FHIR's nested structures into tabular formats—crucial when working with bulk FHIR data.
* Flexpa’s Open Resources
https://my.flexpa.com
* : Free tool to access your health plan data
* Flexpa's Payer Directory: Public directory of payer APIs, location access endpoints, etc.
🔚 Final Thoughts
* The promise of interoperability is not just connectivity—it’s actionable insight, better care, and easier access.
* More orgs should share implementation experiences like Flexpa does to reduce duplication across the FHIR ecosystem.
