Paul Tang, MD, MS
Internist, Palo Alto Medical Foundation 
Adjunct Professor
Clinical Excellence Research Center
Stanford University
Stanford, CA

Paul Tang, MD, MS is an adjunct professor in the Clinical Excellence Research Center at Stanford University and an internist at the Palo Alto Medical Foundation. He was formerly vice president, chief innovation and technology officer at the Palo Alto Medical Foundation and vice president, chief health transformation officer at IBM Watson Health. He has over 25 years of executive leadership experience in health information technology within medical groups, health systems, and corporate settings. 
Most recently, he led the creation, development, deployment, and evaluation of an AI-based clinical decision support application integrated within an electronic health record system. He also led a corporate enterprise-wide design team.

Dr. Tang has chaired numerous federal and private sector advisory and professional association groups related to health information technology and policy. He is an elected member of the National Academy of Medicine, and has served on numerous NAM study committees, including a patient-safety committee he chaired that published two reports: Patient Safety: A New Standard for Care, and Key Capabilities of an Electronic Health Record System. He is a member of the Health and Medicine Division committee of the National Academies of Science, Engineering, and Medicine. Dr. Tang was co-chair of the federal Health Information Technology Policy committee from 2009-2017.  He has served as board chair for several health informatics professional associations, including the American Medical Informatics Association (AMIA). He received his B.S. and M.S. in Electrical Engineering from Stanford University and his M.D. from the University of California, San Francisco.

Statement of Purpose

Machine learning methods have been applied to clinical data from electronic health records (EHRs), primarily in the inpatient and intensive-care settings. We applied machine-learning techniques to support outpatient personalized management of three common chronic diseases by creating precision cohorts of similar patients in similar clinical situations. We presented our dynamic population analysis of treatment outcomes for the index patient’s relevant precision cohort at the point-of-care, integrated within the EHR. We also applied the same precision-cohort analysis to the organization’s entire patient population for each disease. The reports calculate the organization’s potential clinical performance if the best-practice personalized treatments were adopted for each patient.

Our methods focused on developing a repeatable workflow that can be applied to each chronic disease. The workflow includes: (1) defining disease-specific clinical treatment “decision points” that can be automatically extracted from the longitudinal patient EHR data and used for modeling and analysis, (2) identifying appropriate confounding variables for patient similarity matching based on both knowledge-driven clinical guidelines and data-driven feature selection from EHR data, (3) dynamically constructing a precision cohort of patient events that are clinically similar to the current state of the index patient for analysis, and (4) presenting the patient-specific analysis to the clinician at the point-of-care within the EHR.

Target Audience

The target audience for this activity is professionals and students interested in health informatics.

Learning Objectives

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:

  • Understand limitations of applying RCT results in clinical practice
  • Learn a method for analyzing observational data to create precision cohorts of patients similar to an index patient in a similar clinical situation
  • Formulate an approach to visualize and integrate observational data analysis in clinicians’ EHR workflow to inform clinical decisions at the point-of-care
  • Apply analysis of precision cohorts within an organization to derive best practices for common chronic conditions (precision population analytics) 

Accreditation Statement

The American Medical Informatics Association is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians.
