Abstract

Big data technologies are nowadays providing health care with powerful instruments to gather and analyze large volumes of heterogeneous data collected for different purposes, including clinical care, administration, and research. This makes possible to design IT infrastructures that favor the implementation of the so-called “Learning Healthcare System Cycle,” where healthcare practice and research are part of a unique and synergistic process. In this paper we highlight how "big-data-enabled” integrated data collections may support clinical decision-making together with biomedical research. Two effective implementations are reported, concerning decision support in diabetes and in inherited arrhythmogenic diseases.

Keywords: big data, learning health care cycle, data warehouses, data integration, data analytics

Introduction

Following a broadly recognized definition, big data is data “whose scale, diversity, and complexity require new architecture, techniques, algorithms, and analytics to manage it and extract value and hidden knowledge from it.”[1] This definition embraces the multifactorial nature of this kind of data and the technological challenges implied. The integration of different sources of information, from primary and secondary care to administrative data, seems a substantial opportunity that big data provides to healthcare.[2][3][4][5][6] Such integration may allow depicting a novel view of patients' care processes and of single patient's behaviors while taking into account the multifaceted aspects of clinical and chronic care.

The interest in the collection of large and heterogeneous healthcare data sources finds a distinctive application in the definition of novel data-driven decision support systems.[7][8][9] Several authors[8][9][10] define two main fields where researchers should address their efforts to produce valuable results in this area: (i) the secondary use of data to create new evidence and glean important insights to make better clinical decision or to reshape health care organizational components; and (ii) the detection of novel correlations from asynchronous events to allow clinicians to promptly identify potential complications, timely adjust treatments, or help analyze similar manifestations in clinical diagnoses. To pledge better renewed decision making, and consequent successful clinical outcomes, big-data-enabled health care systems should effectively integrate advanced computational tools, including novel similarity measures for patients' stratification, and predictive analytics for risk assessment and selection of therapeutic interventions.[11][12][13][14]

The availability of new data sources is thus leading to the development of a novel model of healthcare, able to fully exploit the potentials of data-driven decision making. The main consequence is that big data will not only be an important enabler for research, but also for the clinical and organizational decision making. We will discuss this perspective within the context of the so-called “Learning Healthcare System Cycle” (LHSC).[15][16][17][18][19][20] We demonstrate the importance of leveraging on LHSC solutions in developing next-generation clinical and organizational decision systems, as follows: (i) we describe a possible formalization for the use of the learning healthcare aystem, proposing a conceptual solution based on state-of-the-art technologies for data production; and (ii) we present two systems implanted upon the LHSC as proof of concept of the validity of the formalized concepts in different clinical scenarios.
