Pre-coffee delivery, post-coffee convictions: Open-source infrastructure deployed across the country is quietly doing more for real public health than most AI press releases. i2b2 is now being deployed statewide in Massachusetts to power Mass CPR for cost-effective, accurate surveillance—including pathogen readiness. By linking EHR data with environmental signals like wastewater, we’re finally doing national-scale population health instead of one-off dashboards. Under the hood is an ontology that actually harmonizes clinical vocabularies across 100 institutions worldwide. And SHRINE has already shown that federated queries can work at scale—up to 60 hospital systems—without centralizing data. This is the unglamorous infrastructure public health should have built decades ago.
