Episode notes
EHRs Were Scaffolding Not The Solution
- Electronic health records were necessary scaffolding but failed to deliver useful intelligence for clinicians.
- ChatGPT-style models showed Wachter that real usable intelligence on top of EHRs is finally possible.
Start With Low-Risk AI To Win Trust
- Deploy AI scribes and chart summarization to reduce clerical work and humanize clinician–patient interactions.
- Start with low-risk tools to win clinicians' trust before moving to higher-stakes decision support.
Sepsis Alert Failure And Local Fix
- Epic rolled out a sepsis alert broadly without adequate real-world testing and triggered massive false alarms.
- University of Colorado retuned the model, routed alerts to specialized nurses, and built relationships to make the tool clinically useful.
