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:
- Defining disease-specific clinical treatment “decision points” that can be automatically extracted from the longitudinal patient EHR data and used for modeling and analysis
- Identifying appropriate confounding variables for patient similarity matching based on both knowledge-driven clinical guidelines and data-driven feature selection from EHR data
- Dynamically constructing a precision cohort of patient events that are clinically similar to the current state of the index patient for analysis
- Presenting the patient-specific analysis to the clinician at the point-of-care within the EHR.
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:
- 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)
