title: The value of information for decision-making in the healthcare environment.
abstract: With their ever-growing importance and usability, the healthcare sector has been investing heavily in medical information systems in recent years, as part of the effort to improve medical decision-making and increase its efficiency through improved medical processes, reduced costs, integration of patients' data, etc. In light of these developments, this research aims to evaluate the contribution of information technology (IT) to improving the medical decision-making processes at the point of care of internal medicine and surgical departments and to evaluate the degree to which IT investments are worthwhile. This has been done by assessing the value of information to decision-makers (physicians) at the point of care by investigating whether the information systems improved the medical outcomes. The research included three steps (after a pilot study)--the assessment of the subjective value of information, the assessment of the realistic value of information, and the assessment of the normative value of information, the results of each step being used as the starting assumptions for the following steps. Following a discussion and integration of the results from the various steps, the results of the three assessment stages were summarized in a cost-effectiveness analysis and an overall return on investment (ROI) analysis. In addition, we tried to suggest IT strategies for decision-makers in the healthcare sector on the advisability of implementing such systems as well as the implications for managing them. This research is uniquely pioneering in the manner in which it combines an assessment of the three kinds of measures of value of information in the healthcare environment. Our aim in performing it was to contribute to researchers (by providing additional insight into the fields of decision theory, value of information and medical informatics, amongst others), practitioners (by promoting efficiency in the design of new medical IS and improving existing IS), physicians (by enhancing the efficient use of information resources), patients (by improving healthcare services) and policy decision-makers in the healthcare sector (regarding the advisability of investments in such systems and suggestions for managing them).
