3rd Workshop on Data Mining for Medicine and Healthcare

April 26, 2014, Philadelphia, PA

To be held in conjunction with 14th SIAM International Conference on Data Mining (SDM 2014)

Overview

In virtually every country, the cost of healthcare is increasing more rapidly than the willingness and the ability to pay for it. At the same time, more and more data is being captured around healthcare processes in the form of Electronic Health Records (EHR), health insurance claims, medical imaging databases, disease registries, spontaneous reporting sites, and clinical trials. As a result, data mining has become critical to the healthcare world. On the one hand, EHR offers the data that gets data miners excited, however on the other hand, is accompanied with challenges such 1) the unavailability of large sources of data to academic researchers, and 2) limited access to data-mining experts. Healthcare entities are reluctant to release their internal data to academic researchers and in most cases there is limited interaction between industry practitioners and academic researchers working on related problems.

The objectives of this workshop are:

1. Bring together researchers (from both academia and industry) as well as practitioners to present their latest problems and ideas.

2. Attract healthcare providers who have access to interesting sources of data and problems but lack the expertise in data mining to use the data effectively.

3. Enhance interactions between data mining, text mining and visual analytics communities working on problems from medicine and healthcare.

SDM is a unique venue for this workshop as leading researchers and practitioners from academia and industry will be able to participate. A workshop where healthcare professionals can have an audience, present and discuss their problems, views and ideas on the field as well as pose research challenges will attract them to SDM. The organizers of this proposed workshop have continuous and in-depth contact with people working on healthcare applications of data mining and healthcare professionals in the US and Europe which will attract a broad and varied set of participants. We believe that this workshop will serve as a bridge between the traditional SDM community and healthcare professionals - two groups of participants that have a lot to learn from and share with each other.

Abstract:
Modeling Patient's Response in Acute Inflammation Treatment

Uncontrolled inflammation accompanied by an infection that results in septic shock is the most common cause of death in intensive care units and the 10th leading cause of death overall. In principle, spectacular mortality rate reduction can be achieved by early diagnosis and accurate prediction of response to therapy. This is a very difficult objective due to the fast progression and complex multi-stage nature of acute inflammation. Our ongoing DARPA DLT project is addressing this challenge by development and validation of effective predictive modeling technology for analysis of temporal dependencies in high dimensional multi-source sepsis related data. This lecture will provide an overview of the results of our project, which show potentials for significant mortality reduction in severe sepsis patients.

Abstract:
Harnessing Social Media to Empower Health Consumers and Discover Healthcare Knowledge 

The healthcare system is currently in the process of transforming from reactive care to proactive and preventive care. Patients are taking an active role in seeking health information to acquire a better understanding of their health conditions and the treatments or medications they are receiving. Patients often go online to search for authoritative information or to communicate with peers who have similar health conditions. Social media plays an important role in empowering patients to acquire healthcare knowledge. The latest sensor and mobile technologies also enable patients to track their health conditions ubiquitously.  In this talk, we’ll look at how the big data contributed by health consumers in social media and the increased connectivity between patients, caregivers, health professionals, and life science researchers are changing the way we conduct patient-centered research.

Abstract:
Learning from observational health data: Lessons from OMOP and OHDSI

Observational healthcare data, such as administrative claims and electronic health records, offer tremendous opportunities to explore the real-world effects of medical products in support of medical product safety surveillance and comparative effectiveness. However, statistical best practices have not yet been fully established for observational analyses. High-profile examples of conflicting results between observational studies and randomized trials or among epidemiologic studies, have caused concern and skepticism within the medical research community about the relative role of observational data in the hierarchy of evidence. Since 2009, the Observational Medical Outcomes Partnership (OMOP) has conducted methodological research experiments to empirically measure the performance of observational analysis approaches across a distributed network of administrative claims and electronic health records. OMOP demonstrated that traditional epidemiologic study designs, such as cohort, case-control, and self-controlled case series, can yield valuable insights about potential effects of exposure, but are all highly susceptible to biases of various sorts that can result in both false negative and false positive findings. OMOP proposed an approach through systematic evaluation and empirical calibration whereby observational study results could be interpreted in the context of their predictive accuracy and operating characteristics. Building on the lessons from OMOP, the Observational Health Data Sciences and Informatics (OHDSI, http://ohdsi.org) program was formed as a multi-stakeholder, interdisciplinary collaborative to create open-source solutions that bring out the value of observational health data through large-scale analytics. In this talk, we will discuss the opportunities and challenges for use of observational data in medical decision-making. We will highlight the progress toward establishing scientific best practices and standardized tools to enable the entire research community to improve the reliability of evidence from observational studies. We will also explore the emerging opportunities to use observational data to go beyond estimating average treatment effects to generating patient-level predictions that provide personalized evidence that’s tailored to the medical history of an individual.

Data Mining and Big Data in Pharma R&D – From disease to therapies

Data mining is used at every stage of drug discovery and development.  From understanding stages of disease to understanding the mechanism of action of drugs and their effects on patients and disease, data mining is an integral part of developing drugs.  As technological advances are enabling is to generate more and more data, we are becoming more dependent on data mining tools, approaches, and skills to help us derive knowledge from our data. Given the ever increasing volume, varieties, and velocity of data being generated today, we will explore the impact of data mining on drug development in this presentation and show examples of how data mining is enabling informed decision making in Pharma R&D and how big data is impacting drug development.

Abstract: 
Privacy Preserving and Knowledge Transfer approaches to Information Exchange in Healthcare

There had been significant efforts in the last few years to improve the accessibility of patient records between disparate health care information systems. In addition to the critical challenges associated with data transformation and data integration, inferring useful knowledge using such data from different sites can introduce several challenges in terms of preserving patient privacy and transferring potentially useful knowledge. This talk consists of two parts. In the first part, we will describe new ways to transfer knowledge between different healthcare systems under patient privacy constraints. In essence, our privacy-preserving predictive models provide a novel mechanism to share knowledge acquired from the multiple data repositories without revealing the actual individual patient-specific information. These models can be almost as accurate as the models built upon centralized data repositories where the entire patient data is revealed. In the second part of this talk, we will describe a new transfer learning approach based on constrained Elastic Net method that can inherently select the appropriate features to effectively transfer knowledge across multiple sites. This approach can also quantify the difference between patient data distributions conditioned upon the corresponding predictive models. Such a difference measure is extremely critical for making the knowledge transfer decisions especially to avoid negative and unsuccessful knowledge transfer. We will demonstrate the performance of the proposed models in two important healthcare problems related to lung cancer and diabetes. The data consists of several electronic health records collected from different states and regions within the U.S. The performance of both the models using various evaluation metrics will be demonstrated and compared with existing state-of-the-art methods.

Abstract:
Change-point models for detecting aberrant gene expression patterns in cancers

In cancer cells, the protein products of oncogenes can be overexpressed without alteration of the proto-oncogene but with shorter 3' untranslated regions (UTRs). During the past few years, RNA-seq has matured as a powerful tool for characterizing gene expressions because of its affordable cost and highly accurate digital resolution. For cancer study, the introduction of RNA-Seq technology, equipped with new analytic methods, makes it possible to capture aberrant shortening or lengthening expression patterns of oncogenes. 
Change-point models are a classical approach to determine whether a change has taken place and where the changes occur. This lecture will introduce change-point models for detecting aberrant gene expression patterns. We develop appropriate parametrical models for characterizing RNA-seq data. In the multiple-testing framework, we will introduce Type I error control and testing efficiency issues for pattern recognition. The numerical performances of the approaches will be illustrated using both simulation study and applications to real cancer data.
