Medical Data Sharing, Harmonization and Analytics

Description

Medical Data Sharing, Harmonization and Analytics serves as the basis for understanding the rapidly evolving field of medical data harmonization combined with the latest cloud infrastructures for storing the harmonized (shared) data. Chapters cover the latest research and applications on data sharing and protection in the medical domain, cohort integration through the recent advancements in data harmonization, cloud computing for storing and securing the patient data, and data analytics for effectively processing the harmonized data. Examines the unmet needs in chronic diseases as a part of medical data sharing Discusses ethical, legal and privacy issues as part of data protection Combines data harmonization and big data analytics strategies in shared medical data, along with relevant case studies in chronic diseases Cover......Page 1 Medical Data Sharing, Harmonization and Analytics ......Page 2 Copyright......Page 3 Preface......Page 4 9.1 Conclusions......Page 346 List of abbreviations......Page 9 1.1 Origin of medical data......Page 14 1.2 Toward medical data sharing and harmonization......Page 16 1.3 Distributed data processing architectures......Page 20 1.4 Scope and contribution to the state of the art......Page 23 1.5 Organizational structure......Page 26 References......Page 30 2 -
