Is doctor google our best choice for healthcare information recommendations? A duty of care to improve processes
No full textLiving with a life-long medical condition or a serious disease requires a lot of research skills on how to access the best quality information to inform better decision-making of healthcare consumers. Relatives, friends, and carers are often sharing the stress and responsibility of looking after the healthcare of consumers. They feel personally responsible for meeting not only physical, but also information needs of people they care for. With the internet being almost a default source of a wide variety of information, and health information in particular, this interview-based chapter reflects on what are the opportunities and challenges for information and communication technology (ICT) researchers who aim to address the personalized needs for quality healthcare information provision. Professor Frada Burstein is a leading information technology researcher specializing in smart information portals in health care. Her research has contributed to the transformations in web-based information systems architecture to empower patients. She was named the ICT Educator of the Year for her pioneering work in knowledge management and ICT education. In this interview with Grant Meredith, she reveals how her intense experiences caring for her father led her to focus her intelligent systems research toward health care
Support for real-time decision making in Mobile Financial Applications
Get PDFMobile users making real-time decisions based on current information need confidence about their context been taken into consideration in producing recommendations. This chapter reviews current use of mobile technologies for decision support. Specifically, it describes a framework for assessing the impact of mobility in decision-making. The framework uses dynamic context representation of data quality to represent uncertainties in the mobile computing environment. This framework can be used for developing visual interactive displays for communicating to the user relevant changes in data quality when working in mobile environment. As an illustration, this chapter proposes a real-time decision support procedure that aims at providing on-the-spot assistance to the mobile consumer when choosing the best payment option to efficiently manage the user’s budget. The proposed procedure is based on multi-attribute decision analysis, scenario reasoning and a quality of data framework. Feasibility of the approach is demonstrated with a mobile decision support system prototype implementation

Knowledge management governance: a multifaceted approach to organizational decision and innovation support
No full textKnowledge management is a strategy to support enhanced decision making through effective control of organizational knowledge. This paper presents a preliminary investigation into the governance of strategies to manage knowledge and the relationship between such strategies and organizational structures. It finds that the federated information transfer model is the 'best fit' with a stakeholder model of governance which ensures accountability and responsibility for tasks meeting the needs of all organizational stakeholders. Further, the governance structure established may predicate the ability of the organization to effectively establish a strategy to manage their knowledge.Presented at: IFIP International Conference on Decision Support Systems; 2004 Jul 1-3; Prato, Italy. p. 889-899.Rights: Suzanne Zyngier, Judy McKay, Frada Burstein © 2004.

Mobile Decision Support for Time-Critical Decision Making
No full textThe wide availability of advanced information and communication technology has made it possible for users to expect a much wider access to decision support. Since the context of decision making is not necessarily restricted to the office desktop; decision support facilities have to be provided through access to technology anywhere; anytime; and through a variety of mediums. The spread of e-services and wireless devices has increased accessibility to data; and in turn; influenced the way in which users make decisions while on the move; especially in time-critical situations. For example; on site decision support for fire weather forecasting during bushfires can include realtime evaluation of quality of local fire weather forecast in terms of accuracy and reliability. Such decision support can include simulated scenarios indicating the probability of fire spreading over nearby areas that rely on data collected locally at the scene and broader data from the regional and national offices. Decision Support Systems (DSS) available on mobile devices; which triage nurses can rely on for immediate; expert advice based on available information; can minimise delay in actions and errors in triage at emergency departments (Cowie & Godley; 2006). Time-critical decision making problems require context-dependent metrics for representing expected cost of delaying an action (Greenwald & Dean; 1995); expected value of revealed information; expected value of displayed information (Horvitz; 1995) or expected quality of service (Krishnaswamy; Loke; & Zaslavsky; 2002). Predicting utility or value of information or services is aimed at efficient use of limited decision making time or processing time and limited resources to allow the system to respond to the time-critical situation within the required time frame. Sensitivity analysis (SA) pertains to analysis of changes in output due to changes in inputs (Churilov et al.;1996). In the context of decision support; traditionally SA includes the analysis of changes in output when some aspect of one or more of the decision model’s attributes change; and how these affect the final DSS recommendations (Triantaphyllou & Sanchez; 1997). In time-critical decision making monitoring; the relationship between the changes in the current input data and how these changes will impact on the expected decision outcome can be an important feature of the decision support (Hodgkin; San Pedro; & Burstein; 2004; San Pedro; Burstein; Zaslavsky; & Hodgkin; 2004). Thus; in a time-critical decision making environment; the decision maker requires information pertaining to both the robustness of the current model and ranking of feasible alternatives; and how sensitivity this information is to time; for example; whether in 2; 5; or 10 minutes; a different ranking of proposed solutions may be more relevant. The use of graphical displays to relay the sensitivity of a decision to changes in parameters and the model’s sensitivity to time has been shown to be a useful way of inviting the decision maker to fully investigate their decision model and evaluate the risk associated with making a decision now (whilst connectivity is possible); rather than at a later point in time (when perhaps a connection has been lost) (Cowie & Burstein; 2006). In this article; we present an overview of the available approaches to mobile decision support and specifically highlight the advantages such systems bring to the user in time-critical decision situations. We also identify the challenges that the developers of such systems have to face and resolve to ensure efficient decision support under uncertainty is provided. </jats:p
A decision support tool for supporting individuals living with long-term conditions make informed choices: LTC-Choices tool for continuous healthcare
Get PDFAn increasing number of individuals are now living with some form of chronic, long-term condition (LTC). The holistic perspective of LTCs makes it important to acknowledge that priorities and decisions are in fluctuation over the course of an individual’s life. The landscape of digital healthcare is full of information systems that capture individuals’ health data, clinical guidelines and/or advice on health conditions, which taken together can help create a comprehensive overview of suitable lifestyle choices to optimise health and well-being. Despite this, there is no evidence of existing frameworks to support individuals living with LTCs from a continuum of care perspective. In this paper, we propose such a multidimensional model for a decision support tool – LTC-Choices. This tool was developed from existing work conducted by the authors around use of multicriteria to support health decisionmaking. We illustrate how LTC-Choices can be implemented using the example of individuals living post-stroke
Developing group support systems for Indonesian culture at the pre-meeting stage of strategy formulation: A proposal and some initial requirements
No full textResearch about Group Support Systems and the design of these group support technologies mainly uses western culture as a point of reference. While the research reveals promising results on the effectiveness of these technologies, the research results and the technologies themselves may be less effective when applied directly to different cultures or cross-cultural situations. This paper aims to explore design requirements for technological support for groups engaged in strategy formulation in Indonesia, a national culture which has relatively high power distance, low individualism, and weak uncertainty avoidance (Hofstede, 1980),and high context (Hall and Hall, 1990). We suggest analysing a typical group meeting activity (strategy formulation) in Indonesia at the pre-meeting stage and propose a programme of research to design and develop supporting technologies in this cultural environment, and then evaluate them in the field. Some results from the early stage of the requirement determination including cultural issues are presented
An interpretive approach to investigating the facilitation of electronically supported distribution teamwork: Some preliminary results
No full textOver the last ten years there have been rapid developments in the electronic technologyavailable to support group work. This has included technology to support groups whosemembers are geographically separate. This electronic technology has been labelled groupsupport systems (GSS). GSS has been shown to provide a number of benefits to groupsarising out of features such as parallel processing, structured decision making processes andovercoming time barriers. Research into face-to-face GSS-supported teamwork has shownfacilitation is an important factor to the success of the interaction. It is likely this is also trueof GSS-supported distributed teamwork. Despite this importance there has been littleresearch into this area. This paper reports on a study which seeks to identify and evaluateinterventions that can facilitate distributed teamwork supported by GSS. The paperdiscusses how the research is based on an interpretive research approach and why this isparticularly effective for researching facilitation. It concludes with a discussion of somepreliminary findings which support the need for facilitation in a distributed environment andthe efficacy of an interpretive approach for facilitation researc
