Data Mining for Medical Informatics (DMMI) is a series of workshops that focus on the use of data mining techniques to address today's challenges in health informatics. The 2015 Workshop on Data Mining for Medical Informatics provides an opportunity for participants to discuss state-of-the-art data mining techniques and review how such techniques can be applied to clinical data. The main theme this year is predictive analytics, which focuses on computational techniques for predicting clinical outcomes under uncertainty, such as risk assessment, diagnosis, prognosis and treatment effects. Predictive analytical methods are currently subject to intense debate in scientific and applied communities for various reasons:

Invited talk abstract:
Predictive analytics to face precision medicine challenges: integrating and fusing data, re-engineering methods and technologies
The long-term goals of the precision medicine initiative aims at predicting optimal therapies for patients and optimal health interventions for citizens by exploiting all available biomedical information, ranging from molecular to clinical variables, and from behavioral to environmental measurements. Predictive modeling is a key component in this scenario, providing methods and tools to derive actionable decision rules of wide clinical applicability.
Starting from a number of projects currently running at the University of Pavia, the talk will present current challenges and potential solutions in predictive modeling to help accomplishing the precision medicine agenda. Modeling issues related to “big data” integration and fusion will be discussed, and ideas to re-engineer existing methods and tools for the joint handling of genomics, clinical and exposomics data will be presented.

Invited talk abstract:
Clinical Alerting of Unusual Care that Is Based on Machine Learning from Past EMR Data
Medical errors remain a significant problem in healthcare. Electronic medical records (EMRs) have shown great promise in helping health care providers to identify and reduce medical errors. Computer-based monitoring and alerting systems play a key role in this effort. We have developed a method for alerting that is based on machine learning from EMRs. In particular, the method uses data in an EMR system to learn a probabilistic model of the usual care of past patients. For a current patient, it derives the probability of each clinical care action that the patient has recently received (e.g., the administration of a given medication). A care action that has a very low probability will trigger a clinical alert that the action is anomalous. We hypothesize that anomalous actions correspond to medical errors often enough to make such alerting worthwhile. This approach has the advantage that it provides broad coverage of clinical care, is completely data driven, can readily adapt to new clinical environments and locations, and can be continually updated over time. This talk discusses the implementation and laboratory evaluation of a version of this system that sends alerts on patients in the intensive care unit (ICU). The results support that this approach is promising.

Invited talk abstract:
Application of Predictive Analytics in Health Care Delivery
The opportunities to apply data mining and medical informatics to clinical care data seem limitless, especially in guiding clinical decision making, facilitating patient management, and improving patient outcomes. In this presentation, Buzz will focus, in particular, on use of electronic health record data and cover: 1) areas of application for predictive analytics and performance requirements; 2) the diversity of data and challenges with using these data, including dominant sources of noise; 3) data driven versus knowledge driven approaches to modeling; 4) considerations in testing models for use in clinical practice; and 5) barriers to translating models to clinical practice.

Invited talk abstract:
Predictive Analytics: The Promise and Problems of Change
New technologies introduce new capabilities but also often highlight difficulties that are unanticipated. Our ability to make statistical predictions from huge data sets enables new scoring, warning and decision support systems. Yet we are mostly unsure of what to predict, how to present those predictions to users, how accurate our predictions need to be, how they can work into the workflow of health care, or whether they will in fact improve outcomes. I will review our successful methods of building predictive models, highlight some needed improvements, and speculate on how we can most positively impact health care.
