A system for identifying and investigating unexpected response to treatment.

Ozery-Flato M, Ein-Dor L, Neuvirth H, Parush N, Kohn MS, Hu J, Aharonov R - AMIA Jt Summits Transl Sci Proc (2015)

Bottom Line: The new system was developed to help researchers uncover new features associated with reduced response to treatment, and to aid physicians in identifying patients that are not responding to treatment as expected and hence deserve more attention.The results provide comprehensive visualizations, both at the cohort and the individual patient levels.We demonstrate the utility of this system in a population of diabetic patients.

ABSTRACT
The availability of electronic health records creates fertile ground for developing computational models for various medical conditions. Using machine learning, we can detect patients with unexpected responses to treatment and provide statistical testing and visualization tools to help further analysis. The new system was developed to help researchers uncover new features associated with reduced response to treatment, and to aid physicians in identifying patients that are not responding to treatment as expected and hence deserve more attention. The solution computes a statistical score for the deviation of a given patient's response from responses observed individuals with similar characteristics and medication regimens. Statistical tests are then applied to identify clinical features that correlate with cohorts of patients showing deviant responses. The results provide comprehensive visualizations, both at the cohort and the individual patient levels. We demonstrate the utility of this system in a population of diabetic patients.
