About Us


To improve the practice and delivery of healthcare by offering researched solutions surrounding the introduction and integration of information and decision technologies into the healthcare system. CHIDS’ research focuses on applications and processes that impact safety, quality, access, efficiency and return on investment.


The Center for Health Information and Decision Systems (CHIDS) at the Robert H. Smith School of Business, University of Maryland is an academia-led effort with collaboration from industry and government affiliates, designed to research, analyze, and recommend solutions to challenges surrounding the introduction and integration of information and decision technologies into the health care system.

Through mutually beneficial partnerships, CHIDS is structured as a research and development center with the goal of conducting rigorous research, disseminating information, managing knowledge, and coordinating collaborations among concerned stakeholders. In addition, CHIDS serves as a focal point for thought leadership around the topic of health information and decision systems. Since its inception in 2005, CHIDS has been creating intelligence around the design, implementation and use of information and decision technologies in the healthcare domain.

CHIDS draws on the expertise of the Decision, Operations and Information Technologies (DO &IT) department at the Smith School, the University of Maryland Medical System, School of Public Health, Behavioral and Social Sciences, and other assets in the University of Maryland network. CHIDS offers the benefit of a world-class staff with hundreds of published manuscripts related to technology implementation, adoption, assimilation, workflow design, decision sciences, and value of IT. The DO&IT department includes information systems, operations management, and management science disciplines and is staffed with over 30 professors and more than 30 PhD students and research assistants. The pool of talent, knowledge and expertise in D&IT is acknowledged by several publications as a Top-5 performer in research production worldwide. The Information Systems group is ranked in the top-10 worldwide in Business Week and U.S. News and World Report.

CHIDS' core team consists of faculty, fellows and students involved in the day-to-day operations and management of the center. In addition to the core team, CHIDS affiliated faculty, the advisory board, and Smith School staff members play key roles for the center in various activities. The CHIDS student fellows provide support in the research process and also lead independent research projects.
