We keep asking whether AI can outperform doctors. A new Nature Health study (May 1, 2026) flips the question: do PATIENTS perform differently when the listener is an AI?

In a preregistered, randomized, between-subjects experiment of 500 adults, participants who believed they were chatting with an AI chatbot — versus a human physician — produced symptom reports that were ~8% less suitable for an initial urgency assessment (Cohen's d = 0.34, P<0.001). Same prompts. Same conditions. Just a different perceived listener.

Clinical perspective: Self-triage AI is only as good as the history it gets. If patients withhold or compress information when they assume the other end is a machine, even a well-validated model will mis-triage. This is a behavioral failure mode that won't show up in benchmarks where the input data is curated. It's also a reminder that FDA clearance — and even strong model accuracy on vignettes — does not equal real-world clinical performance.

Strengths: preregistered, randomized, peer-reviewed, decent sample size. Limitations to weigh: simulated rather than real clinical encounters, GPT-5.2 used as the rater of report quality (LLM-as-judge), and a single recruitment platform. A useful signal, not a final answer.

The takeaway for clinicians and health-system leaders deploying patient-facing AI: design the front door for trust and disclosure. Coach patients on what to share. Audit what gets lost.

A new milestone in AI-guided cardiology just landed — and it deserves a closer look from clinicians.

On April 28, 2026, the U.S. FDA cleared (and CE Mark approved) Abbott's Ultreon™ 3.0 Software — the first optical coherence tomography (OCT) platform in the U.S. and Europe to integrate high-resolution intravascular imaging with AI-automated plaque analysis during percutaneous coronary intervention (PCI).

Why it's clinically meaningful:

• A single 1-second OCT pullback produces cross-sectional coronary images at higher resolution than IVUS — and with low-or-zero contrast, which matters for the ~25% of CAD patients who also have chronic kidney disease.

• AI characterizes plaque morphology and supports the interventionalist in selecting optimal stent size and landing zones, then performs a post-procedure assessment to confirm restored flow.

• With over 600,000 PCIs performed annually in the U.S. and 885,000+ in Europe, even modest gains in precision and consistency could translate into meaningful patient-level outcomes at scale.

The bigger story is one we're seeing across specialties: AI is moving out of "future tech" framing and into bedside decision support. Our job as physicians isn't to compete with these tools — it's to understand them well enough to deploy them wisely, recognize their limits, and keep the patient at the center.

I unpack tools like this — clinical use, workflow impact, and ethical trade-offs — on my YouTube channel. Search "AskDoctorAsh" on YouTube, or DM me.

From Immigrant Dreams to Resident of the Year: A Journey of Service, Resilience, and Purpose

Hey everyone!

I'm still trying to process what it means to hold the Resident of the Year and Guzman Award in my hands. These aren't just accolades—they're the weight of every sleepless night spent at a patient's bedside, every moment of doubt I pushed through, every small victory that reminded me why I chose this path. They carry the echoes of countless conversations with worried families, the quiet satisfaction of making a difference, and the overwhelming privilege of being trusted with human lives in their most vulnerable moments.

But these awards hold an even deeper significance for someone who never imagined they'd be possible. As an immigrant who arrived with dreams bigger than my suitcase and hope heavier than my fears, every step toward this moment felt like walking through fog—uncertain, sometimes lonely, but always moving forward. There were nights I questioned whether I belonged here, whether my accent would be understood, whether my differences would be seen as deficits. These awards are proof that our backgrounds don't limit our futures—they enrich them.
My heart has always been drawn to public health, to advocacy, to lifting others as I climb. These honors whisper what I've always hoped to be true—that showing up authentically, leading with empathy, and never forgetting where you came from isn't just enough, it's exactly what medicine needs. They remind me that every time I chose compassion over convenience, mentorship over personal gain, I was building something bigger than myself.

My voice breaks a little when I think about everyone who made this possible. To my mentors—you saw potential when I only saw obstacles. To my attendings—you pushed me to be better even when I thought I had nothing left to give. To my co-residents—you became the family I never knew I needed, sharing both the weight of our calling and the joy of small victories.

As I transition into my role as a hospitalist physician and educator, these awards serve not as endpoints but as waypoints—reminders of the responsibility we carry and the impact we can make when we lead with purpose, serve with humility, and never stop climbing toward our highest potential.

To anyone watching who feels like their dreams are too big, or their path too uncertain—keep going. Your background isn't a barrier; it's your superpower. Keep believing, keep serving, keep climbing.
The journey continues. 🩺
