Our Research

Our lab specializes in analysis of temporal data, development of clinical software, and clinical trials. One central question underlies our work: How can new technology enable emergency care that is safer, more effective, and more efficient?

For our recent publications, please see Dr. Reisner's Catalyst page.

Trauma

Trauma is a leading cause of death in young adults. Our team has studied hundreds of trauma patients to characterize patterns of vital-sign abnormalities caused by life-threatening hemorrhage (i.e., bleeding); developed “artificial intelligence” software to automatically identify patients with life-threatening hemorrhage (the software was successfully tested on-board Boston MedFlight); and developed computer simulations to understand how dehydration hurts patients with hemorrhage.

Blood Pressure

Circulatory shock is a life-threatening condition involving poor blood circulation, often treated in an ICU with powerful medications to maintain safe blood pressure. We have developed techniques to predict when critically ill patients will develop worse blood pressure; and when they require a change in medication dosage. Starting 2025 our team has started a number of hypertension projects -stay tuned for more info.

Spine

Spinal Cord Injury

After acute spinal cord injury, patients better recover neurological function if blood pressure is maintained within specific ranges. But blood pressure varies through time and frequently falls out of the goal range. Our lab developed the VIGORIS software system which uses artificial intelligence to guide ideal blood pressure management, and we are conducting clinical trials, funded by the Massachusetts Spinal Cord Injury Cure Research Program.

Sepsis

Sepsis is a leading cause of death in US hospitals. Our team developed a sepsis management protocol that significantly reduced antibiotic delays at MGH; addressed a serious risk that is inherent in too many automated sepsis detection algorithms; and developed a novel methodology to interpret sepsis data with improved validity.

Society of Critical Care Medicine (SCCM) Presentation: Improving ICU Blood Pressure Control Through Clevidipine Dosing

Our team presented new findings on factors influencing blood pressure control during clevidipine infusion in ICU patients. Results show that faster dose titration and fewer failed weaning attempts are strongly associated with improved blood pressure control. These insights highlight actionable strategies for optimizing hypertension management in critical care. Download Presentation Here

New Publication! Advancing Personalized Care with a Novel Predictive Modeling Framework

Our team co-authored a new report describing a predictive model that begins with a population-level approach and dynamically transitions to a personalized model as patient-specific data becomes available. This adaptive framework enables more accurate, individualized predictions over time, with potential to improve clinical decision-making. Thanks to Prof. Jin-Oh Hahn and Richard Kao for leading this effort! Click here to read the article.

New England Journal of Medicine AI Publication: FDA-Cleared Algorithm for Hemorrhage Risk Prediction

Our team co-authored a publication in NEJM AI detailing the development and FDA clearance of APPRAISE-HRI, an AI-enabled clinical decision support tool for assessing hemorrhage risk in trauma patients. This work represents a major milestone as one of the first FDA-cleared AI software systems for real-time risk stratification in acute care. The algorithm leverages vital sign data to help clinicians rapidly identify patients in need of urgent intervention.

Neurocritical Care Society Presentation: Faster Clevidipine Titration Reduces Time to Target Blood Pressure

Our team presented a neurocritical care study examining how clevidipine dosing strategies impact time-to-target blood pressure. We found that faster titration was strongly associated with significantly shorter time to reach goal blood pressure. These findings highlight the importance of rapid dose adjustment in optimizing hypertension management in neurocritical ICU patients. Download Poster Here
