@grod11.bsky.social; @jlsalinas.bsky.social: Ending contact precautions for VRE did not increase transmission. Long-read genomics shows that mobile genetic elements circulate independently of strains, suggesting new priorities for prevention. doi.org/10.1017/ash....

Proud to be a co-author with @jlsalinas.bsky.social on this @nature.com paper on healthcare-associated E. faecium. Recent ISL3 expansion may accelerate adaptation to healthcare environments, with metabolic consequences that help explain its growing clinical burden. www.nature.com/articles/s41...

Proud to share the first installment of our exploration of wastewater-based epidemiology to understand AMR transmission. Many lessons learned re:feasibility, sustainability, and promise in real-world healthcare epidemiology. www.sciencedirect.com/science/arti...

Now open: the EUCIC Certificate in Infection Prevention and Control (2026–2028) 🌍 A 2-year advanced program for current and future IPC leaders! 🦠 🎓 Scholarships available. 🔗 www.escmid.org/education/eu...

A glimpse of how I used AI (LLMs) and spaced repetition to pass the ID boards! @ashejournal.bsky.social

New in ICHE from @grod11.bsky.social et al: Using secure AI agents integrated within the EMR for the evaluation of blood culture appropriateness LLM agents showed: ▶️ High sensitivity (77.4%) ▶️ Low specificity (36.1%) ▶️ framing, sycophancy, & semantic cues vital #IDSky 📄: doi.org/10.1017/ice....

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. Check out our CLABSI paper: pmc.ncbi.nlm.nih.gov/articles/PMC...

If you’re feeling sad that #IDWeek is coming to an end tomorrow, don’t worry, ESCMID Global is just around the corner! Abstract submissions are now open. It’s such a wonderful conference where I’ve met friends and collaborators from all over the world! www.escmid.org/congress-eve...

This study evaluated oral vancomycin primary prophylaxis effectiveness in preventing C. difficile infection (CDI) in BMT patients. Bayesian Meta-analysis showed reduced CDI incidence during hospitalization. We present an innovative approach to adjust for publication bias. doi.org/10.1017/ash....

Just realized — this is my first talk as a newly minted attending and hospital epidemiologist! Grateful to the Mile High APIC chapter for the opportunity!

Excited to share the podium with colleagues, collaborators, and my academic grand-mentor while presenting on AI in healthcare epidemiology at the APIC Mile High Colorado Chapter!

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

Colegas en México 🇲🇽: ESCMID busca campeones locales para difundir conocimiento en enfermedades infecciosas. Gran oportunidad para representar a México, unirse a grupos de trabajo internacionales y crecer profesionalmente. 👉 Postúlate aquí: www.escmid.org/about-us/net...

Denver Health is hiring: Medical Director of Antimicrobial Stewardship & ID physician (musculoskeletal + inpatient consults). IDSA Center of Excellence • 525-bed hospital • Univ. of Colorado training site. Details: denverhealth.wd1.myworkdayjobs.com/DHHA-Main/jo... — connect at #IDWeek!

📣Open call ESCMID is creating a brand-new #Vaccines Subcommittee. 💉 We are looking for a director to establish this new subcommittee including defining the strategic directives. Interested persons can review the call document: www.escmid.org/about...#Vaccines #IDSky #MedSky #clinmicro

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!

Proud of @grod11.bsky.social he gave two oral presentations on his molecular and wastewater-based hospital epidemiology work at #SheaSpring2025 @stanfordmedicine.bsky.social

@grod11.bsky.social talking about long-read WGS to discern pre/post contact precautions of transmission of VRE in blood 👏🏻👏🏻👏🏻 #SHEASpring2025

Excited to be appointed as the ESCMID Local Champion for the U.S. for the next three years! After many rewarding experiences, I look forward to promoting ESCMID Global and championing infectious diseases—especially the often-overlooked field of healthcare epidemiology!

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: doi.org/10.1128/jcm....

🆕💫Large scale multicenter study in US BC use was associated with unit type, hospital bed size & region Highest bld cx use: Medical ICUs Single blood culture & positive blood culture rates were below 10% across all 4 unit types( medical/surgical ICU/Ws) #idsky #EMIMCC jamanetwork.com/journals/jam...

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. doi.org/10.1017/ice....

@jlsalinas.bsky.social loving these approaches to test LLMs for IP&C! Very straightforward and very detailed. Love the supplement info

🆕 LLM for IP&C Inquiries: 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. @kbrustepi.bsky.social, @grod11.bsky.social, @jlsalinas.bsky.social #IDSky 📄: doi.org/10.1017/ice....

Bayesian reasoning is fun.

LLMs won’t take our jobs, but learning to work with them is the future. And no, not all LLMs are made equal! In this great collaboration, we tested LLMs for helping infection preventionists—GPT-4 outshined GPT-3.5, Microsoft Copilot, and OpenEvidence @jlsalinas.bsky.social doi.org/10.1017/ice....

Welcome to the new Stanford Infectious Disease fellowship class! Excited for you to learn, grow, and have fun in Silicon Valley

The readability of scientific articles went down over time. Should we thank "sounding important for the journal" for this trend? Or deeper niche-specialization? 📄Source: https://buff.ly/4hj40HI

Honored to be part of the Stanford Health Care team recognized with the Malinda Mitchell Award for Quality. Through collaboration, including blood culture stewardship I led with great support from @jlsalinas.bsky.social and others, we made a real impact on reducing CLABSI. Proud of our team’s work!

A picture is worth a 1000 words! My biggest pet peeve? Slides with a 1000 and zero images. Pro tip: I use ChatGPT to create visuals for my talks—no coding skills needed most of the time. Occasionally, I do need to tweak the code to improve the images!

A bit out of my comfort zone as a healthcare epidemiologist discussing novel therapeutics for resistant Gram-negative infections, but excited for the opportunity!

Stanford ID has an abundance of cool cases, great people, and, most importantly, food for the faculty, fellows, and trainees! 😝

We are happy to be expanding our reach into the wide open Bluesky! Be sure to follow us for all updates on our Society and on the upcoming #ESCMIDGlobal 2025. #IDsky #medsky

I came across this beautiful paper on aerosol generation (or lack thereof, haha) during routine patient care activities. Only nebulizations were linked to significant aerosol production. Interesting note: bronchoscopy without nebs showed no significant aerosols. doi.org/10.1093/cid/...

Feels nice to follow back people that follows me without worrying about bots

Ironically, my first peer-reviewed publication that wasn’t a case report was on the safety of the MMR vaccine using publicly available data—prompted by a rise in disinformation during a measles outbreak and selected as editor’s choice in OFID. academic.oup.com/ofid/article...

I’ll start highlighting our recent work on LLMs for CLABSI surveillance www.cambridge.org/core/journal...
