Watch the Recording
Santiago Romero-Brufau, MD, PhD, is an Assistant Professor of Medicine and Healthcare Systems Engineering at Mayo Clinic, where he also serves as Principal Data Scientist for the Department of Medicine. His work focuses on the development and implementation of machine-learning models into clinical practice. He is also instructor in the Department of Biostatistics and in Health Data Science at the Harvard T.H. Chan School of Public Health.
Statement of Purpose
Physiological deterioration in the hospital is often unrecognized and can lead to increased patient mortality. To improve the identification and response to acute deterioration, more than 70 early warning scores have been developed. Some recent models have used machine learning to increase prediction accuracy for adult acute inpatient deterioration, but the value of nursing assessments and the incorporation of interaction variables has not been sufficiently explored. MC-EWS uses a machine learning approach and incorporates nursing assessments and clinically relevant interactions as predictors to achieve a higher predictive accuracy.
The target audience for this activity is professionals and students interested in health informatics.
The general learning objective for all of the JAMIA Journal Club webinars is that participants will
- Use a critical appraisal process to assess article validity and to gauge article findings' relevance to practice
After participating in this webinar, the listener should be able to:
- Measure the accuracy of predictive models using clinically-relevant metrics
- Incorporate clinically-relevant interaction variables into machine learning prediction models
- Recognize the predictive value of nursing assessments for the prediction of inpatient deterioration
