We collected data from a large, tertiary care, multi-specialty urban hospital system. In these hospitals about 2450 patients were in a diabetes case management program and from this cohort we obtained the EMRs of 1,687 patients. We use a two-stage machine learning algorithm that combines structured and unstructured data to predict the transitions in patients\u2019 health states. We use a technique that we term \u2018Differential Parsing\u2019 where the output of the algorithm\u2019s first stage prediction is used to identify those instances where there are key information signals in unstructured data. We then use LDA algorithm to extract decision rules from unstructured data which then enter as inputs for the second stage of the prediction. We construct four ML algorithms and contrast these with regression-based models. We find that the use of unstructured data improves the prediction accuracy of ML algorithms and they outperform regression-based models.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Is That A Sugar High or High Sugar?
