You can also revisit our poster with great colleagues at the Veterans Affairs Health System! We analyzed 24-year national trends of resistant Enterobacterales and Pseudomonas in urine cultures from spinal cord injury patients. Proud of those maps I coded myself 😜 #IDWeek2025

If you’re still around at #IDWeek2025, stop by poster 1967! If not, here it is — a workflow using LLMs on real patient data showed limited performance compared to an ID expert in adjudicating blood culture appropriateness.

Couldn’t agree more! The criteria also fail to keep up with emerging molecular diagnostics, leading to unfair penalties!

Couldn’t ask for a better way to close out my trainee years than highlighting our work at #SHEASpring2025 — from idea generation to funding, to grabbing wastewater and running tests. Learned epi, IPC, comms, and more! Thanks to @jlsalinas.bsky.social for being the best mentor I could ask for!

Facing the blood culture shortage, we implemented an order alert and restricted repeat cultures within 72 hours to high-yield indications. Spearheaded by our incredible micro lab and supported by our 2-year stewardship initiative, details here:

Up to 79% of providers order blood cultures without evaluating the patient first—lots of room to improve! Honored to collaborate on this national study, led by Johns Hopkins, exploring blood culture practices across 8 US academic institutions.

Authors investigated four LLM AI tools’ accuracy. Most provided acceptable answers to IP&C questions. Their use to supplement IP&C consults should be further explored.

The readability of scientific articles went down over time.
Should we thank "sounding important for the journal" for this trend?
