A DATA ANALYTICAL FRAMEWORK FOR IMPROVING REAL-TIME, DECISION SUPPORT SYSTEMS IN HEALTHCARE
In this dissertation we develop a framework that combines data
mining, statistics and operations research methods for improving
real-time decision support systems in healthcare. Our approach
consists of three main concepts: data gathering and preprocessing,
modeling, and deployment. We introduce the notion of offline and
semi-offline modeling to differentiate between models that are based on known baseline behavior and those based on a baseline with missing information. We apply and illustrate the framework in the context of two important healthcare contexts: biosurveillance and
kidney allocation. In the biosurveillance context, we address the
problem of early detection of disease outbreaks. We discuss integer
programming-based univariate monitoring and statistical and
operations research-based multivariate monitoring approaches. We
assess method performance on authentic biosurveillance data. In the kidney allocation context, we present a two-phase model that
combines an integer programming-based learning phase and a
data-analytical based real-time phase. We examine and evaluate our
method on the current Organ Procurement and Transplantation Network (OPTN) waiting list. In both contexts, we show that our framework produces significant improvements over existing methods
ISBIS 2016: Meeting on Statistics in Business and Industry
This Book includes the abstracts of the talks presented at the 2016 International Symposium on Business and Industrial Statistics, held at Barcelona, June 8-10, 2016, hosted at the Universitat Politècnica de Catalunya - Barcelona TECH, by the Department of Statistics and Operations Research. The location of the meeting was at ETSEIB Building (Escola Tecnica Superior d'Enginyeria Industrial) at Avda Diagonal 647.
The meeting organizers celebrated the continued success of ISBIS and ENBIS society, and the meeting draw together the international community of statisticians, both academics and industry professionals, who share the goal of making statistics the foundation for decision making in business and related applications.
