Can Machine Learning Algorithms use Contextual Factors to Detect Unwarranted Clinical Variation from Electronic Health Record Encounter Data during the Treatment of Children Diagnosed with Acute Viral Pharyngitis

This study demonstrates that machine learning algorithms leveraging contextual electronic health record features can effectively detect absolute unwarranted clinical variation, specifically inappropriate antibiotic prescriptions for pediatric acute viral pharyngitis, offering a scalable and interpretable alternative to traditional statistical methods.

Real-world EHR-derived progression-free survival across successive lines of therapy informs metastatic breast cancer risk stratification

This paper presents a scalable framework that reconstructs metastatic breast cancer treatment lines from real-world EHR data using radiology-anchored progression evidence to generate individualized, interpretable progression-free survival estimates that enable robust risk stratification across diverse patient subgroups and successive lines of therapy.

AI-Generated Responses to Patient's Messages: Effectiveness, Feasibility and Implementation

This study evaluating the implementation of Epic's GenAI tool for patient messaging in a Dutch academic hospital found that while initial adoption was high and drafts were well-structured, the tool ultimately failed to improve clinical efficiency or well-being, leading to declining usage due to barriers such as limited time savings, content inaccuracies, and misaligned expectations.

Act or Defer: Error-Controlled Decision Policies for Medical Foundation Models

This paper introduces SO_SCPLOWTRATC_SCPLOWCP, a stratified conformal framework that enables the safe clinical deployment of medical foundation models by controlling false discovery rates for immediate actions and providing calibrated, coverage-guaranteed prediction sets for deferred cases, thereby optimizing healthcare resources and reducing costs in ophthalmology and neuro-oncology.

On the robustness of medical term representations in locally deployable language models

This study evaluates the representational robustness of 15 locally deployable large language models on neurological terminology, revealing that while performance generally scales with model size, neither size nor medical fine-tuning guarantees clinical reliability due to significant variations based on terminological complexity and subdomain.

Does the Sleep Regularity Questionnaire capture objective sleep-wake regularity? Evidence from wearable and sleep diary data.

This study finds that while the Sleep Regularity Questionnaire shows modest agreement with subjective sleep diary measures, it demonstrates only weak correspondence with objective smart ring data, suggesting it is best used as a complementary tool rather than a replacement for objective monitoring in healthy adults.
