‍Episode 208 - Show Notes:

[00:00:07] Episode preview

[00:05:16] Why ICU medicine showed healthcare as a team sport powered by data, technology, and trust.

[00:05:44] How consumer AI like Netflix inspired Dr. Rojas to ask why predictive intelligence wasn’t helping critically ill patients.

[00:06:13] The fellowship project that sparked his informatics career: predicting ICU readmissions to prevent premature discharges.

[00:06:43] Why Dr. Rojas believes AI should function as “augmented intelligence,” supporting clinicians—not replacing them.

[00:08:05] Where AI performs best in healthcare: short-term, physiologic predictions like sepsis and ICU deterioration.

[00:08:51] Why human-driven outcomes like readmissions and length of stay break many predictive models.

[00:10:10] The case for evaluating AI like a drug or device—measuring real-world value, alert burden, and workflow impact.

[00:11:49] The hidden barrier to health equity analytics: inconsistent definitions of race, ethnicity, language, and gender.

[00:12:45] Why health system averages can hide disparities—and how stratified data reveals where care is failing.

[00:14:36] Inside Rush’s AI governance playbook: silent testing, local validation, and equity checks before deployment.

[00:17:34] How Rush uses AI to identify high-risk patients for social needs screening when data is incomplete.

[00:19:24] Why bias and/or imperfect data should not halt progress, as long as health systems actively work to improve fairness over time.

[00:22:37] How ignoring data bias is like skipping hand hygiene.

[00:26:57] Attribution as a major challenge in analytics and why agreeing on definitions before surfacing performance data is paramount.

[00:28:48] The informaticist as a bicycle frame between clinicians and data teams, translating needs across clinical and technical worlds.

[00:33:34] Recounting a failed AI rollout where overlapping scores created confusion, showing how trust and clarity matter more than model accuracy.

[00:37:37] Why AI adoption often fades over time, citing alert fatigue, workflow disruption, and unnoticed system changes that break models.

[00:43:22] Principles for localizing AI models, including silent testing, predefined success thresholds, and strong clinical champions.
